Crimping hole glue injection accelerating and cleaning device for PCBA board with signal interference prevention function

Abstract

The invention relates to the field of PCBA boards, in particular to a crimping hole glue injection accelerating and cleaning device for a PCBA board with a signal interference prevention function. According to the technical problem, the crimping hole glue injection accelerating and cleaning device for the PCBA board with the signal interference prevention function is provided. According to the technical scheme, the crimping hole glue injection accelerating and cleaning device for the PCBA board with the signal interference prevention function comprises a glue dripping and conveying mechanism, a glue pushing and cleaning mechanism, an edge glue processing mechanism and the like; the glue pushing and cleaning mechanism is arranged on the side surface of the glue dripping and conveying mechanism; and the glue pushing and cleaning mechanism is connected with the edge glue processing mechanism. According to the device, glue injection of a crimping hole of the PCBA board can be accelerated, residual glue on the inner ring face and the edge of the crimping hole of the PCBA board can be effectively cleaned away while a production period is shortened, it can be ensured that the PCBA board is not damaged during cleaning, and the signal interference resistance of the PCBA board is ensured.

Description

technical field [0001] The invention relates to the field of PCBA boards, in particular to a device for accelerating glue injection and cleaning of crimping holes of PCBA boards for accelerating the prevention of signal interference. Background technique [0002] PCBA board, also known as printed circuit board, printed circuit board, often uses the English abbreviation PCB, is an important electronic component, a support for electronic components, and a provider of circuit connections for electronic components. Because it is made using electronic printing techniques, it is called a "printed" circuit board. Before the appearance of printed circuit boards, the interconnection between electronic components relied on the direct connection of wires to form a complete circuit. Now, the circuit breadboard only exists as an effective experimental tool, and the printed circuit board has become an absolute dominant position in the electronics industry. [0003] At present, various h...

Problems solved by technology

[0005] In order to overcome the long period of the process when scraping the glue on the plastic sheet into the crimping hole of the PCBA board, and because the hole diameter of the plastic sheet is larger than the crimping hole of the PCBA board, it is easy to make the glue remain in the Around the upper edge of the crimping hole of the PCBA board, and because the thickness of the colloid in the crimping hole of the PCBA board is 0.2 to 0.4mm, there will be residual colloid on the inner ring surface of the crimping hole of the PCBA board, which will seriously affect the access of the connector, thus Affect the quality of the finished product, weaken the anti-signal interference ability of the finished product, and the colloid remains around the upper edge of the crimping hole of the PCBA board, and the flatness of the PCBA board is greatly affected, resulting in a decline in the later use performance. The technical problem of the present invention is: to provide A PCBA board crimping hole glue injection and cleaning device for accelerating anti-signal interference
