Description

Technical Field

[0001] The invention relates to the field of circuit board processing, and in particular to a circuit board fixing device. Background Art

[0002] PCB, Chinese name for printed circuit board, also known as printed circuit board, is an important electronic component, the support of electronic components, and the carrier of electrical connection of electronic components. Printed boards have developed from single-layer to double-sided, multi-layer and flexible, and still maintain their own development trends. Due to the continuous development towards high precision, high density and high reliability, the continuous reduction of volume, reduction of cost and improvement of performance, the printed board still maintains a strong vitality in the development of future electronic equipment. During the processing of PCB boards, they have to go through multiple processes such as printing, etching, drilling, etc. In the process of transferring from one process to the next, the PCB board needs to be stored on a fixed bracket.

[0003] Patent application number: CN201920339187.6 discloses a PCB board fixing bracket, including a bottom plate and a bolt, a slide groove is provided on the bottom plate, two vertical plates are provided above the bottom plate, and one-piece fixed blocks are provided on both sides of the vertical plates, and a through hole through which the bolt passes is provided on the fixed block, and the bolt passes through the aforementioned through hole and is threadedly fixed to the slider below the aforementioned slide groove, and a fixing groove I is provided on the opposite surfaces of the two vertical plates, and a screw rod is fixed on all sides of the upper end surface of the bottom plate, and a pressing plate is also provided above the bottom plate, and a through hole through which the screw rod passes is provided on the pressing plate at a position corresponding to the screw rod on the aforementioned bottom plate, and a nut is provided on the screw rod above the pressing plate, and a fixing groove III is provided on the lower end surface of the pressing plate, and a fixing groove II is provided on the upper end surface of the bottom plate to cooperate with the aforementioned fixing groove III to fix the PCB board. Place the PCB board in the fixing groove II of the bottom plate, adjust the position of the two vertical plates, fix the left and right sides of the PCB board, slide the pressing plate down along the screw rod, contact the upper end surface of the PCB board, tighten the nut, and fix the pressing plate. Thus, the circuit board is fixed. However, this type of fixing bracket fixes the circuit board and then transfers it to the next process. When taking out the circuit board in the next process, the four nuts need to be removed first, and after the nuts are removed, the pressure plate needs to be removed from the screw rod. Only after the pressure plate is removed can the circuit board be taken out, which makes it very troublesome to take out the circuit board, seriously affecting the processing efficiency of the circuit board.
