Detection device for detecting electrical performance of electronic circuit board

Abstract

The invention discloses a detection device for detecting the electrical performance of an electronic circuit board. The detection device comprises a plurality of probes which are fixed on a substratethrough a motor base. Each probe comprises a pushing mechanism at the bottom and a detection mechanism at the top. The pushing mechanism comprises a linear motor, and a circular tray is arranged at the top end of the push rod of the motor. A guide column is fixed in the center of the tray. A spring is nested on the guide column. A probe seat is fixed to the top end of the spring. A probe is led out from the center of the top of the probe seat. A run-through long and thin pipeline is formed at the center of the top of an insulating shell outside the probe seat and the guide column, and the probe penetrates out of the pipeline. The substrate is connected with a control panel. The control panel is provided with an FPGA (field programmable gate array), a motor driving module, an ADC module andan RS232 interface module used for being connected with a PC unit. Compared with the traditional manual detection method, the above device is high in efficiency, good in stability and convenient forbatch operation. The leaked detection and the wrong detection can be effectively prevented. In addition, the recording and the statistics can be realized, so that the detection process of each circuitboard can be traced.

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
