An electronic circuit board electrical performance testing device

Abstract

The invention discloses a device for detecting electric performance of an electronic circuit board, which comprises a plurality of probes fixed on a substrate through a motor seat, the probes include a push mechanism at the bottom and a detection mechanism at the top; the push mechanism includes a linear motor, and the top of the motor push rod is provided There is a circular tray, the center of the tray is fixed with a guide post, and a spring is nested on the guide post; the probe seat is fixed on the top of the spring, and the top center of the probe seat leads upward to the probe; the probe seat and the top center of the insulating shell outside the guide post form a The penetrating slender pipe, the probe passes through the pipe; the substrate is connected to the control board, and the control board is equipped with an FPGA, a motor drive module, an ADC module and an RS232 interface module for connecting to a PC. Compared with the traditional manual detection method, the invention has high efficiency, good stability, convenient batch operation, can effectively prevent missed detection and wrong detection, and can also realize recording and statistics, so that the detection process of each circuit board can be traced back.

Description

technical field [0001] The invention relates to a detection device, in particular to a detection device for electrical performance of an electronic circuit board. Background technique [0002] At this stage, in the mass production of electronic circuit boards, the placement work is generally completed by the placement machine. Compared with manual welding, the precision and efficiency of the placement machine have been greatly improved. However, in actual use, it is inevitable that there will be poor welding problems. Therefore, the circuit board pasted by the placement machine cannot be directly loaded into the product. If there is a problem with the debugging of the whole product, the circuit board needs to be disassembled and repaired, resulting in a waste of manpower. [0003] Generally speaking, before the complete machine assembly of the product, the processing factory will conduct all inspections or sampling inspections on the circuit boards. Correspondingly, in the ...

Problems solved by technology

[0005] The above-mentioned testing process is generally completed manually. This process is relatively boring and cumbersome, and it is a simple repetitive labor. In actual operation, problems such as missed detection and wrong detection are prone to occur. Moreover, the efficiency of this process is low, which will affect the entire production efficiency. If you want to speed up the progress, you must arrange multiple workers to inspect at the same time
