A side ramp is provided on the inner side of the cleaning head to prevent collision with the detection part during the transverse movement.

[0028] The above-mentioned transverse moving bracket 16 is slidably connected to a limit rod 17, one end of which is fixedly connected to the limit block 15, and the other end is fixedly connected to a stop block 22.

During the movement of the transverse moving bracket, the limit block and the L-shaped rod move along the slide groove of the cleaning bracket through the support shaft. At the same time, the cleaning wheel moves along the slide groove of the cleaning bracket, and the elastic piece sleeved on the limit rod is stretched by the stop block, thereby driving the cleaning head to clean one end of the detection piece to remove dust on the surface. A side inclined platform is provided on the inner side of the cleaning head to prevent collision with the detection piece during the transverse movement.

[0053] The slide groove of the cleaning bracket is provided with a bending part and a straight part, so that the cleaning head can be located in the bending part when not cleaning, so as not to interfere with the normal picking up and placing of the inspection part by the feeding rod. After one inspection is completed, the feeding rod will move in the opposite direction along the same trajectory, causing the screw rod to rotate in the opposite direction, thereby resetting the cleaning head.

[0054] When the above-mentioned electronic device loading jig is used, it drives the screw to rotate, so that the transverse bracket drives the cleaning wheel to move along the slide groove of the cleaning bracket. During the movement of the cleaning wheel, the cleaning head can clean the side of the detection part on the clamping table, and can remove impurities on the surface of the electrical contact point of the detection part, thereby avoiding the situation where the adhering dust affects the detection and improving the reliability of the detection.
