The tray separation mechanism 220 separates a plurality of trays with products stacked in the loading bin 210 into a tray to be inspected. The tray linear conveying assembly 310 conveys the tray to be inspected to the camera inspection mechanism for inspection. If feeding is required, the tray linear conveying assembly 310 conveys the tray to be inspected to the feeding station. After the Tray to be inspected moves to the feeding station, the feeding transport mechanism 120 transports the products in the feeding tray to the Tray to be inspected that needs feeding, and then transports the Tray to be inspected to the camera inspection mechanism for inspection. If feeding is still needed, the Tray linear conveying assembly 310 transports the Tray to be inspected to the feeding station for feeding. If feeding is not needed, the Tray to be inspected forms a Tray to be stacked, and the Tray linear conveying assembly 310 transports the Tray to be stacked to the support mechanism 530. The Tray ejection mechanism 520 lifts the Tray to be stacked sent by the Tray linear conveying assembly 310, and the support mechanism 530 supports the Tray to be stacked.

[0060] In one embodiment, if Figures 2 to 4As shown, the feed tray conveying mechanism 110 includes a feed tray linear conveying assembly 111, a feed tray support and positioning assembly, a first barcode scanning gun 114, and a feed ejection assembly 118.

Then, the feeding tray with the products is placed on the push-pull tray assembly 116. Since a groove is provided at the front end of the feeding tray, the groove can cooperate with the positioning protrusion provided on the front end positioning block 115. Then, the push-pull tray assembly 116 is reset. A downward pressure is applied to the feeding tray by the first lower pressure plate 112 assembly, and an upward thrust is applied to the rear end of the feeding tray by the upper positioning assembly, so that the feeding tray is firmly positioned. Then, the feeding tray is transported to the target position by the feeding tray linear conveying assembly 111 to prepare for feeding.

[0062] In order to facilitate the removal of products from the Tray, the present application is provided with a loading and ejecting assembly 118. When in use, the feeding tray is moved under the drive of the feeding tray linear conveying assembly 111, one area of ​​the feeding tray is moved to the loading and ejecting assembly 118, and then the product is pushed upward by the support on the upper top block 118b to loosen the product, which is convenient for subsequent removal of the product. After the product in one area is taken out, the feeding tray is moved under the drive of the feeding tray linear conveying assembly 111, so that another area of ​​the feeding tray is directed toward the support on the upper top block 118b, and then the product is pushed upward by the support on the upper top block 118b to loosen the product.

[0063] In one embodiment, if Figures 6 to 8 As shown, the tray separating mechanism 220 includes a lifting support assembly 221, a tray assembly 222 and a separating assembly 223, the lifting support assembly 221 is arranged below the loading bin 210, the tray assembly 222 is respectively arranged on both sides of the loading bin 210, and the separating assembly 223 is respectively arranged on both sides of the loading bin 210. When it is necessary to separate a tray to be inspected, the lifting support assembly 221 rises to the tray receiving position, the tray assembly 222 retracts, the tray separation assembly 223 extends out and supports the upper tray, and leaves the lowest tray, which is the tray to be inspected. The tray to be inspected is supported by the lifting support assembly 221, and the lifting support assembly 221 descends to the waiting position, and the tray to be inspected is received by the tray tray bracket 320, and the tray to be inspected on the tray tray bracket 320 is positioned by the tray positioning assembly 330, and the tray assembly 222 extends out and supports the tray in the loading bin 210 through the tray assembly 222, and the tray separation assembly 223 retracts.

[0064] Specifically, the jacking support assembly 221 includes a first support plate 221a and a first jacking mechanism 221b.
