Abstract

The invention relates to a PCB detection device, in particular to a PCB clamping mechanism during detection. The PCB clamping mechanism is provided with a fixed seat; the fixed seat is arranged on a guide rail of an engine base; one side of the fixed seat is provided with a screw rod for driving the fixed seat to move forward and backward on the guide rail; the PCB clamping mechanism is arranged on the fixed seat; a front retainer is fixedly connected with the fixed seat and a back retainer is slidably connected with the fixed seat; the front retainer is in pin connection with at least one fixture; the fixture consists of a chuck arranged above the front retainer and a top block arranged below the front retainer; a spring is arranged below the front retainer and is pressed against the top block; and a post rod mechanism is pressed against the top block when the fixed seat is moved to the top front end along the guide rail. The PCB detection device is simple in structure, and can conveniently and quickly perform fixture on a PCB, and improves the working efficiency; meanwhile, the PCB fixture has comparatively stable fixture on the PCB, and ensures the distinct capture images of a camera on the PCB so as to improve the accuracy of PCB detection.

Description

technical field [0001] The invention relates to a PCB board detection device, in particular to a clamping mechanism for PCB board detection. Background technique [0002] Usually, when inspecting the PCB board, it is necessary to clamp and fix the PCB board, and then use the camera to shoot the PCB board and compare it with the pre-stored information in the computer, so as to detect the installation position of the electronic components on the PCB the goal of. Usually, the mechanism used to clamp the PCB on the testing equipment is either poor in clamping stability, and the PCB board is prone to slight displacement during the testing process, thereby affecting the testing structure, or the clamping mechanism is relatively complicated, and the loading and unloading of the PCB board is not convenient, reducing the work efficiency. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the clamping mechanism when fixing the PCB, the pres...
