How to clean the automatic dispensing machine How to use the dispensing machine

Keep the speed dispenser clean If the downtime is long, clean it immediately (not ask you to use water) The air source should be kept dry, and it is best to install an air filter, because the air source contains moisture, which will shorten the life of the controller for a long time.

The three-axis dispensing machine is not much different from the four-axis dispensing machine, and the four-axis dispensing machine has graphic elements such as drawing points, straight lines, polylines, three-dimensional arcs (spatial arcs), circles, ellipses, runways, distances, spirals, coatings, automatic fillets, irregular three-dimensional spline curves, etc., and fully realizes 360-degree rotation dispensing.

There will always be a time to change the rubber type during the use of the automatic dispensing machine, how to clean the feeding parts of the automatic dispensing machine is a very important technology, and the maintenance of the dispensing machine is also very important, only three points need to be done: such as.

1.To replace the rubber seed, the pipeline needs to be cleaned. At this time, close the feeding valve first, open the discharge valve, discharge the remaining rubber in the rubber barrel, close the discharge valve, open the feeding valve, pour the cleaning solvent into the rubber storage barrel, activate the body, and press out the solvent for flushing according to the usual operation mode.

2.If the air pressure intake is abnormal and there is water vapor, please remove the water vapor in the pressure regulator filter or check whether the air pressure source is abnormal. 3.Please wipe the machine part regularly to increase the service life.

Do you clean **? Whether you use a syringe for glue or a pressure bucket for glue.

The dispenser is to put the integrated block or other components to be applied on the substrate after gluing, and fix it after drying!

Truth be told, every dispenser is different, and you have to ask the manufacturer who bought the dispenser for instructions to know how to use it, or ask the manufacturer to send someone to train you.

1. Check whether the automatic dispensing machine is clean, water vapor and other problems that directly affect the normal operation of the machine before starting.

2. It is not allowed to touch the dispensing head, needle nozzle, guide chain and other moving parts under the working state to prevent pinching accidents.

3. If you find a special situation, you can press the red emergency button in front of the fuselage to stop the machine immediately.

4. When the equipment needs to be moved, the gas path and power supply must be cut off before it can be carried out.

5. Don't pile too many things next to the machine to avoid improper operation.

6. It is necessary to wear gloves during operation, and try not to expose the **, so as not to get the glue on the body and have bad factors.

7. When operating the glue, you should have an understanding of the glue, the use of the situation, how to use it normally, so that it can be operated normally.

8. Regularly test the safety performance of the automatic dispensing machine.

9. Don't put anything on the workbench and keep it clean.

10. In the case of non-use for a long time, cut off the power supply.

The first step is to send compressed air to a syringe or a plastic bottle. Before that, it is necessary to ensure that the syringe or plastic bottle is clean and free of contamination. In daily dispensing operations, care should be taken not to mix different glues in one container.

If there is a requirement for mixing and dispensing, the cartridge should be cleaned in time after mixing. After using the glue, place the glue in a cool, ventilated and dry place that is not easy to touch. Tighten the rubber cap to prevent colloid leakage.

When there is a large amount of leakage, it can be cured with water and then scraped off.

The next step is how to press the glue into the feed pipe connected to the piston chamber. In the compression process, the scope of compression, the specification of the style, and the requirements for the surface all directly affect the quality of the lamination. The relevant variables should be strictly controlled to ensure the quality of dispensing.

In the glue lamination process, the glue is pressed into the pipeline, and the needle flows out in a state or spot shape according to the dispensing requirements for a short stay in the pipeline. When the piston is in the upstroke, the piston chamber is filled with pre-added glue. When the piston is pushed down on the dispensing needle, the glue is squeezed and pressed out of the nozzle.

The final process is glue discharge. In the process of dispensing, there is often a phenomenon that the size of the glue is inconsistent or the glue is not smooth. At this time, it is necessary to check and confirm the four links.

The first is the glue ratio, many times, the glue is not smooth due to the glue is too silky. Another thing to check is the working air pressure, which should be maintained appropriately and steadily. The third thing to pay attention to is the patency of the pipeline.

The last thing to pay attention to is whether the temperature of the mating device is normal. It needs to be pointed out.

Yes, the amount of glue dripping is determined by the distance the piston is downstroked and can be adjusted manually or programmed.

Of course, the choice of dispensing machine still needs to be based on the actual needs of the product, you can consult the manufacturer's technical personnel first. Suzhou Qunlida dispensing machine will answer for you!

Dispensing machine: It is to apply the glue to the product according to the preset path to achieve the purpose of bonding, fixing, waterproof, anti-vibration and so on. It is divided into several parts: dispensing machine hardware, dispensing software, dispensing valve and controller, and glue.

Dispensing is to dispense and coat UV glue, conductive glue, heat dissipation glue, and AB glue to the designated position of the workpiece through the dispensing device.

There are three modules involved:

Dispensing hardware: dispensing machine (manual, automatic, and some machines with visual, light source, height measurement module) Dispensing software: industrial control system, dispensing system, 3D glue detection system glue:

Waterproof adhesive, special adhesive, heat dissipation silicone, UV glue, conductive glue, heat dissipation glue, AB glue and so onHere's how it worksThrough the cooperation of the above three modules, the dispensing hardware moves according to the preset path, the glue is dispensed according to the proportion, and the dispensing software is designed and the path is taken.

Collaborate on dispensing. Composition dispensing machine.

The automatic dispensing machine is to pre-point a special glue at the position on the PCB board that needs to be patched to fix the SMD components, and then go through wave soldering after curing. Dispensing is done automatically according to the program. Tubular rotary dispensing control; Normal, digital time controller.

The dispensing pen head is equipped with a micro-touch switch, which is easy to operate; No air pressure is required, and it can work when connected to the power supply.

On the one hand, the working principle of the Archimedean dispensing pump is that compressed air is fed into the plastic bottle (syringe), which is pressed into the feed pipe, and the glue flows through a screw that rotates at a fixed time and at a specific speed. The rotation of the screw creates a shear force on the adhesive, which makes the adhesive flow down the thread, and the rotation of the screw continuously pressurizes the adhesive to make it flow out of the tip of the dispensing needle.

And it has the flexibility to have no fixed dot size. It can be adjusted by software. However, when dripping large glue dots, the screw rotation time is long, which will reduce the output of the whole machine.

In addition, the viscosity and flow characteristics of the adhesive can affect its stability.

On the other hand, the non-contact dispensing pump works on the principle that compressed air is fed into the bottle (syringe) and pressed into the feed pipe connected to the piston chamber, where it is heated and the temperature is controlled to achieve the best possible stickiness. Using a ball structure, the glue fills the gaps left by the retraction of the ball from the seat.

When the ball returns, the force generated by acceleration breaks off the gel flow, causing it to eject from the tip of the dispensing needle and drip onto the plate to form a glue dot. It not only eliminates the glue tip tailing produced by traditional methods, but also eliminates the wear and tear of the dispensing needle, the problem of interference from other parts and the damage of the nozzle.

Beijing Shenlong Technology Co., Ltd. is designed and customized on demand, and the two-component glue filling machine and automatic gluing robot are widely used and are well recognized by customers.

Add methylene chloride to dissolve in the solution, remove all glue-stained dispenser benches, and soak in the solution. After some time, the glue will dissolve naturally. After dissolving, a final wash is carried out with hydrogen peroxide.

After cleaning, wipe with a dry cloth. Because methylene chloride is cleaned thoroughly and the cost of use is not high, but this chemical is volatile, and large amounts of use may cause air pollution, the use of this liquid should be minimized.

Cleaned with a high-pressure water gun, this square pisson is only suitable for cleaning when the glue has not yet fully solidified. That is, when the glue has just stuck to the surface of the dispenser, it should be cleaned immediately. Otherwise, even if the glue is washed with high-pressure water after it has set, the adhesive will not be completely eliminated.

This method has low cost, obvious effect and good cleaning effect. However, this method can be a waste of water resources and can cause water pollution if not done properly.

The use of environmentally friendly solvents can be cleaned, this method is also highly advocated by our users, this method is not only environmentally friendly, but also more thorough, and there will be no pollution.

The above are the above three methods for removing residual glue on the workbench of the automatic dispensing machine, which shows that the third method is a more practical method at present. Of course, we should find a method that really works for us based on the actual situation.

There are two types of dispensing methods, one is contact dispensing and the other is non-contact dispensing. Contact dispensing is mainly a syringe pressure type, so that the dispensing tip is in contact with the surface of the product as much as possible for dispensing operations; Non-contact dispensing is jetting.

No glue or uneven dispensing: first check the storage barrel of the dispensing machine, whether the material is sufficient, whether there is a foreign body blocked in the transmission pipeline, whether the air pressure is normal, and whether there is a problem with the dispensing valve.

Dispensing position: Normally, desktop dispensers have a dispensing positioning accuracy of up to mm. If the dispensing position is off, then we go to check whether the needle position is correct, and then whether there is any problem when setting the program.

The problems encountered by the automatic dispensing machine in dispensing are: the dispensing valve is blocked, which is because the curing time of the glue is short, or it is not used for a long time, and it is not cleaned up in place after use. The dispensing speed is slow, the amount of glue is inconsistent, and the dispensing is due to glue interruption or bubbles.

The constant control system of Ruidexin automatic dispensing machine controls the problem of glue.

Problems such as blocked dispensing valves and inability to supply materials often occur.
