Requirements for sensor dispensing

With the development of electronic computer and information technology, the demand for sensors is increasing rapidly, and it is becoming more and more important in mobile phones and other electronic devices. Most distance sensors used in mobile phones and other electronic products need to be finished by dispensing. Dispensing is to eliminate the clutter of sensors, eliminate interference, avoid sensor misjudgment, and achieve a high accuracy In order to meet the needs of the market, the performance of relevant manufacturing equipment such as dispenser and dispenser needs to be further improved.

The sensor in the application of dispensing process needs to meet what requirements, at the same time, what problems and difficulties will appear, I will explain for you.

Dispensing application requirements

① No more glue, less glue and overflow

② Do not deviate

③ Do not splash glue

④ No lack of glue

⑤ The thickness should be consistent

Problems and difficulties encountered in dispensing process

1、 Polyglutinate

Cause analysis:

1, not switched to single point injection.

2. Too many dispensing points in flight.

3. The nozzle diameter is too large.

4. Valve opening time is too long.

2、 Less glue

Cause analysis:

1. It is not switched to single point injection;

2. Too many dispensing points in flight;

3. The nozzle diameter is too large;

4. Valve opening time is too long.

3、 Glue splashing

Cause analysis:

1. The stroke of the striker is too large;

2. The glue spraying height is too high.

4、 Lack of glue

Cause analysis:

1. The marking speed is too fast;

2. Glue.

5、 Overflow

Cause analysis:

1. The level of the middle part clamp is not adjusted well, and it is crooked;

2. The programming is not well programmed, which leads to more spurt and more crooked;

3. The nozzle is not clean and glue is hung.
