Description

Technical Field

[0002] The glue dispensing device is a mechanism that uses an air source to push the glue in the glue dispensing tube and apply it to the product. It is widely used in the processing of semiconductor PCB boards. That is, during the processing of PCB boards, after the electronic components on the board are fixed, the connecting pins of the electronic components on the board are sealed with glue for protection by glue dispensing.
