Double-sided circuit board testing device

Abstract

The invention provides a double-sided circuit board testing device. The device includes a testing device body, the testing device body comprises a longitudinal detection mechanism, a transverse detection mechanism, a test base, a vertical side plate, and a feeding mechanism. The feeding mechanism is fixedly installed on the test base, the vertical side plate is located on one side of the feeding mechanism and fixedly installed on the test base, the longitudinal detection mechanism and the vertical side plate are connected and located above the feeding mechanism, and the transverse detection mechanism and the vertical side plate are connected and located between the feeding mechanism and the vertical side plate; the transverse detection mechanism is connected with a lifting mechanism, the transverse detection mechanism is connected with a moving mechanism, and the longitudinal detection mechanism and the transverse detection mechanism are provided with detection probes corresponding totest contacts on a double-sided circuit board. By testing the two sides of the double-sided circuit board at the same time, labor is thus reduced, the working time is reduced, the production efficiency is improved, the cost is reduced, the practicability is high and the device is easy to popularize.

Description

technical field [0001] The invention relates to the field of circuit board testing, in particular to a double-sided circuit board testing device. Background technique [0002] Domestic research on the automatic detection system of printed circuit boards began in the early and mid-1990s, and it has just started. There are relatively few scientific research institutes engaged in research in this area, and because of the influence of various factors, the research on the automatic optical inspection system for printed circuit board defects also stays at a relatively early level. Because the automatic detection system of printed circuit boards in foreign countries is too expensive, and the automatic detection equipment of printed circuit boards in the true sense has not been developed in China, most domestic circuit board manufacturers still use manual inspection with a magnifying glass or a projector. method to check the side. Due to the high labor intensity of manual inspecti...

Problems solved by technology

Because the automatic detection system of printed circuit boards in foreign countries is too expensive, and the automatic detection equipment of printed circuit boards in the true sense has not been developed in China, most domestic circuit board manufacturers still use manual inspection with a magnifying glass or a projector. check side

Due to the high labor intensity of manual inspection, the eyes are prone to fatigue, and the missed inspection rate is high

Moreover, with the development of electronic products towards miniaturization and digitalization, printed circuit boards are also developing towards high density and high precision.

It is completely impossible to inspect higher density and precision circuit boards

[0003] At the same time, due to the fact that in actual production, the shape of the circuit board is varied, and the points to be tested are not necessarily on the same plane. Currently, there is a double-sided circuit board with test points in the horizontal and vertical directions. The best test method is to use two sets of test fixtures to complete the detection of the double-sided circuit board, which consumes more man-hours and manpower, resulting in low production efficiency and high cost
