Is the dispensing amount always inaccurate? Wrong glue? Poor
Release date：2021-08-24 08:56 Views： 1. Check whether the air pressure is normal. When the air pressure is unstable, there will be wrong points and leakage points. At this time, a pressure regulator can be equipped or the pressure of the rubber valve can be controlled to stabilize the rubber output.
2. Also check the dispensing time. The longer the dispensing time, the more stable the dispensing will be.
3. When the fluidity of glue is weak, wire drawing occurs because of the use of high viscosity glue. The remedy is that there is glue between the glue outlet of the glue head and the glue valve. It will be delayed for a period of time until the glue runs out.
4. The lifting height is that when the dispensing of one track is completed, move to the space at the starting point of the next track, lift the rubber head a little higher at the end point to ensure that the rubber head is safe from collision, and then move to the starting point of the next track.
Formal operation skills:
1. The dispensing effect directly affects the dispensing quality of the dispensing machine. How to control the dispensing amount is the key to the success of dispensing.
2. The effect of glue output control is not only related to the set parameters, but also related to the maintenance of automatic dispensing machine.
There are several reasons for poor control of glue output of automatic dispensing machine
1、 The air pressure of the air pipe is not enough, so the effect of glue output control is not obvious
2、 Leakage and too small glue output occur
3、 The dispensing needle is blocked due to the secondary use of the dispensing needle. The air pressure of automatic dispensing should be controlled within an appropriate range. Overpressure and low air pressure are not allowed. If the air pressure is not within the required range, it is easy to cause poor glue output. The main reason is that the problem of insufficient air pressure occurs only when the air pressure tank of the dispensing machine is unstable. The air inlet gauge should be adjusted to about 11 to 14 psi, The air pipe pressure should be above the glue output control of the automatic dispensing function.

The main reason for dripping during dispensing is that the glue concentration is not enough, resulting in the glue flowing down the needle during dispensing. As long as the vacuum suction function is added, a certain amount of pressure difference between the interior of the dispensing valve and the external atmospheric pressure can be used to close the dispensing valve to control the glue output, In order to improve the control of glue output, it is necessary to maintain the dispensing machine. If it is necessary to use the automatic dispensing machine to complete the special arc dispensing, in addition to controlling the glue output, it is also necessary to complete the arc path programming through the dispensing controller to improve the dispensing quality. The repetition accuracy will be affected after the arc path dispensing for a long time. Therefore, the maintenance and adjustment of the automatic dispensing machine can improve the quality of arc dispensing.
