Problems solved by technology

[0004] The areas covered by PCBA test fixtures include PCBA test machines, PCBA fixtures, PCBA test components, etc. The entire test fixture covers the entire process of PCBA testing. Now when testing, manual handling and manual testing are performed, and the test efficiency is low. At the same time, optical inspection cannot be performed during the inspection process, and optical inspection needs to be moved to other stations for inspection

Abstract

The invention provides a PCBA automatic test fixture which comprises a test equipment body and a detection table top installed in the middle of an inner cavity of the test equipment body. A raw material support is fixedly installed on the edge of the detection table top, a body frame is arranged on the outer edge of the test equipment body, a test assembly is bolted and fixed to the horizontal position of the top of the body frame, a discharging track is arranged on the side face of the test equipment body in a penetrating mode, an indication signal lamp is vertically embedded and fixed to thecorner of the top of the body frame, and a control host is embedded in the front face of the body frame. A PCBA board is detected through a test assembly installed at the top, the test assembly can adjust spatial position change, micro adjustment can be achieved in the whole adjustment process, and it is guaranteed that the whole equipment has good detection position changes. Meanwhile, an adjustable detection assembly at the top can achieve optical detection on the surface of a PCBA board to be detected, detection items are increased, data measurement and calculation of PCBA board surface detection are guaranteed, and the detection accuracy is improved.
