[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] In this invention, the first motor drives the conveyor belt via a transmission shaft. When the part to be inspected is transported between two push blocks, the second motor is started to drive the rotating shaft to rotate. The rotating shaft drives the bidirectional screw to rotate synchronously via a transmission belt, thereby causing the two transmission plates to move closer to each other along the direction of the guide rod. This causes the two push blocks to push the part to be inspected to the center of the conveyor belt. At the same time, the rotating shaft drives the rack to slide upward in the working groove via gears, thereby causing the two baffles to slide upward in the slide groove, opening the inspection protective cover. After the part to be inspected is delivered to the area below the visual inspection camera, the second motor rotates in the opposite direction to indirectly move the baffles downward to start the inspection. By pushing the part to be inspected to the center and then closing the inspection protective cover for inspection, the accuracy of visual inspection is improved.

[0013] In this invention, a visual inspection camera is used to capture image information of parts, and a supplementary light provides sufficient light for visual inspection. By retracting and pulling the connecting ring and the sliding rod through the electric push rod, the sliding rod slides in the groove while driving the rotating block to rotate around the fixed rod, thereby adjusting the angle of the supplementary light to adapt to the inspection needs of different parts.
