[0022] Specifically; in the present embodiment, the conveying component 1 is configured as a slide rail 13, and a storage plate is provided on the slide rail 13. The bottom surface of the storage plate is provided with a ball structure adapted to the slide rail 13. The electrically controlled pneumatic products to be inspected are placed on the storage plate. At the same time, a notch is provided on the outward side of the slide rail 13. The conveying component 1 can transport the storage plate exactly to the notch position each time it conveys.

[0023] The conveying assembly 1 also includes a slide cylinder 12 arranged on a side away from the clamping assembly 2. The output end of the slide cylinder 12 extends upward and is provided with a rectangular block, which is located exactly at the notch on the slide rail 13. Therefore, by controlling the slide cylinder 12 to extend upward, the rectangular block can squeeze the side wall of the storage platform, thereby pushing it toward the clamping mechanism. The structure of the slide cylinder 12 is shown in the attached figure. Figure 4 The position shown in the figure is arranged below the slide rail; the slide cylinder 12 can also be replaced with a position opposite to the clamping component 2, and the output end is fitted with the end surface of the storage table, so that the storage table is pushed toward the clamping component 2.
