Description

Technical Field

[0001] The utility model relates to the technical field of diode processing, in particular to a multi-station light emitting diode glue dispensing device. Background Art

[0002] A diode, also known as a crystal diode, or simply a diode, is an electronic device that conducts current in one direction. There is a PN junction and two lead terminals inside the semiconductor diode. This electronic device has the ability to conduct current in one direction according to the direction of the applied voltage. Currently, in order to bond a diode to a circuit board, it is necessary to first apply glue to the diode, and then bond the diode to the circuit board.

[0003] When the existing dispensing device is in use, glue flows out from the dispensing head to dispense glue on the diode. After the dispensing is completed, the electric valve inside the dispensing head is closed. However, after the dispensing head is closed, some glue will still remain inside the lower end of the dispensing head, and then harden when in contact with the outside air, causing the dispensing head to be blocked. At this time, it takes time for manual labor to wipe and clean it with alcohol before it can be used, resulting in the diode dispensing processing device cannot be used in time. Therefore, in response to the above problems, we propose a multi-station light-emitting diode dispensing device. Utility Model Content
