AI Technical Summary

Technical Problem

The existing circuit board detection tool is easily affected by encoder accuracy and load changes under the control of servo motors, resulting in misalignment of the circuit board pins and probes, resulting in short circuit damage and economic losses.

Method used

By setting up the baffle and limit components, the main power supply of the belt conveyor is disconnected after the circuit board is moved to the test position, ensuring that the circuit board is accurately staying in the test position, and then turning on the branch power supply after the test, achieving accurate movement and testing of the circuit board.

Benefits of technology

Without affecting the detection efficiency, ensure that the circuit board moves accurately during testing, avoid short-circuit damage caused by misalignment, and reduce economic losses.

Abstract

The invention relates to the technical field of circuit board detection, in particular to a circuit board detection tool which comprises a belt conveyor, a testing assembly, a limiting assembly, a baffle, a square frame, a lifting plate, a clamping assembly and a timing switch, and the testing assembly is installed on the side wall of the belt conveyor and extends to the position above the belt conveyor. The limiting assembly is installed on the inner wall of the belt conveyor, the square frame is horizontally connected with the limiting assembly in a sliding mode, and the lifting plate is vertically installed in the square frame in a sliding mode. A baffle plate is arranged to intercept a circuit board, a main power supply of the belt conveyor is disconnected after the circuit board moves to a test station, a branch power supply of the belt conveyor is connected after the test is finished, and the baffle plate moves downwards to lose the interception effect of the circuit board and then is reset, so that the problem that the servo motor controls the test position of the circuit board is solved; and the circuit board pins and the probes are misplaced due to the influence of the encoder precision and the load change of the servo motor.
