Description

A PCBA board crimping hole injecting glue and cleaning device for accelerating prevent signal interference
Technical Field
The invention relates to the field of PCBA boards, in particular to a PCBA board crimping hole glue injection and cleaning device for accelerating signal interference prevention.
Background
PCBA boards, also known as printed circuit boards, are often referred to by the acronym PCB, are important electronic components, are supports for electronic components, and are providers for the wiring connections of electronic components. It is called a "printed" circuit board because it is fabricated using electronic printing techniques. Before the appearance of printed circuit boards, interconnections between electronic components are made by direct connection of wires to complete the circuit. Circuit boards are now only available as an effective experimental tool, while printed circuit boards have become an absolute dominant place in the electronics industry.
At present, various hardware boards are generally integrated with a plurality of electronic components through a PCB substrate to form a PCBA board, so that the integration level of the electronic components is improved, the space occupation is reduced, for connectors with a large number of devices installed on the PCBA, in order to improve the installation efficiency, the prior art generally completes batch installation through a crimping process, namely crimping control is performed on the PCB, then the corresponding connectors are crimped and installed in crimping holes, however, more external electromagnetic signals exist on the back surface of the crimping holes and enter the connectors through the external electromagnetic signals, thereby influencing the connectors, leading the signal interference resistance of the finished PCBA board to be weaker and the operation performance to be reduced, therefore, the prior art provides the PCBA board capable of preventing the signal interference, when carrying out the colloid to this anti-signal interference's PCBA board crimping hole, through pasting flourishing offset plate on the PCBA board, then pour the colloid on flourishing offset plate, then scrape the colloid on flourishing offset plate into PCBA board crimping hole, this process cycle is longer, and because flourishing offset plate opens the hole diameter and is greater than PCBA board crimping hole, consequently make the colloid remain around PCBA board crimping hole top edge easily, and because colloid thickness son is 0.2 to 0.4mm in the PCBA board crimping hole, therefore PCBA board crimping hole ring face portion can exist and remain the colloid, seriously influence the access of connector, thereby influence the finished product quality, weaken the anti-signal interference ability of finished product, and the colloid remains around PCBA board crimping hole top edge, the roughness influence of PCBA board is great, lead to later stage performance to decline.
Therefore, a need has arisen for a device that can accelerate the injection of glue into the crimp holes of the PCBA board, reduce the production cycle, and effectively clean the annulus and the residual colloid at the edges in the crimp holes of the PCBA board, and ensure the anti-signal interference capability of the PCBA board without damaging the PCBA board during cleaning.
