Description

Technical Field

[0001] The utility model relates to the technical field of PCB circuit boards, and particularly relates to a PCB circuit board defect detection device. Background Technique

[0002] In the electronics industry, a PCB (Printed Circuit Board) is a basic component used to support and connect electronic components and is a core component of almost all electronic devices. With the continuous popularization and complication of electronic products, the quality and reliability requirements for PCBs are also getting higher and higher. Therefore, in order to ensure the quality of PCBs, defect detection has become an indispensable part of the electronic manufacturing process. PCB manufacturing usually includes processes such as printing, soldering, and assembly. The manufacturing process of printed circuit boards involves processes such as lithography, etching, and drilling. In these processes, various defects may occur, such as open circuits, short circuits, poor soldering, via holes, etc. If these defects are not detected and repaired in time, it will lead to a decline in product performance or even failure.

[0003] Chinese Patent CN214622942U discloses a PCB circuit board defect batch detection device, including a workbench and support columns. The top of the workbench is fixedly connected with a backboard, the top of the backboard is fixedly connected with a top board, the bottom of the top board is fixedly connected with support columns, the bottom of the top board is fixedly connected with a second hydraulic cylinder, and the bottom of the second hydraulic cylinder is fixedly connected with a second telescopic rod. This PCB circuit board defect batch detection device solves the problem of being inconvenient to fix and adjust according to the width of the circuit board by setting a fixed seat, guide rods, a second driving motor, a screw rod, and an adjusting block. When the second driving motor is turned on to drive the screw rod to rotate, since opposite external threads are provided on the outside of the screw rod, the two adjusting blocks will move towards each other on the screw rod and the guide rods, and the circuit board can be clamped and fixed according to the width of the circuit board, making it more suitable for fixing the circuit board. However, the clamping structure of this patent is too simple, and fixing by means of threads will make the fixing not firm enough, and it is easy to shake or fall during detection, seriously affecting the detection effect. Therefore, a PCB circuit board defect detection device is proposed to address the above deficiencies. Content of the Utility Model
