PCB (printed circuit board) positioning and blowing jig

Abstract

The invention discloses a PCB (printed circuit board) positioning and blowing jig which comprises a base and an air compressor. The PCB positioning and blowing jig is characterized in that a boss is arranged on the base, each rotary retaining plate is arranged at the top of the boss and comprises a retaining strip, a movable shaft sleeve and a positioning shaft, each retaining strip is connected on the corresponding positioning shaft through the corresponding movable shaft sleeve in a sleeved manner and can rotate around the positioning shaft, blowing holes are arranged on a boss area formed by surrounding of the rotary retaining plates, an air inlet is arranged on the side face of the base and connected with an air outlet of a blowing electromagnetic valve, and an air inlet of the blowing electromagnetic valve is connected with the air compressor. By the PCB positioning and blowing jig, the problems that a lot of dust and sweeps can be left on a PCB, using effect of a PCB can be affected, damage to the PCB is caused, service life of the PCB is shortened, and blowing effect is affected due to the fact that the PCB is prone to moving during blowing are solved; the PCB positioning and blowing jig is stable and motionless in processing and capable of quickly removing the dust and the sweeps left on the PCB.

Description

technical field [0001] The invention relates to a fixture, in particular to a PCB board positioning air blowing fixture. Background technique [0002] The Chinese name of PCB board is printed circuit board, also known as printed circuit board and printed circuit board. It is an important electronic component, a support for electronic components, and a provider of electrical connections for electronic components. Because it is made using electronic printing, it is called a "printed" circuit board. After the PCB board is soldered with electronic components, a lot of dust and waste will remain on the PCB board, which will greatly affect the use effect of the PCB board, cause damage to the PCB board, and shorten the service life of the PCB board. At the same time, when the PCB board is blowing, it is easy to move due to the large air flow, which affects the actual use effect and cannot effectively remove dust and waste.

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problem of soldering electronic components on the PCB board in the prior art, a lot of dust and waste will remain on the PCB board, which will affect the use effect of the PCB board, cause damage to the PCB board, and shorten the service life of the PCB board. It is easy to move when blowing air, which affects the blowing effect. The invention provides a simple structure, stable processing without movement, and can quickly remove residual dust and waste on the PCB board, ensure the use effect, and prolong the service life of the PCB board.
