[0002] In the watchcase manufacturing industry, appearance detection is an indispensable link to ensure product quality. The existing detection method usually relies on a long conveying line, and the watchcase is transported to two different detection positions on the conveying line, and detection is performed on the corresponding sides of the two positions respectively to cover the two corresponding sides of the watchcase. Although this detection method meets the demand of quality detection to a certain extent, it has significant efficiency bottlenecks and flexibility limitations.

[0063] The carriers 4 carrying products move to the left base 1 after detection on the front conveying path, and then the two carrying tracks on the left base 1 change positions repeatedly to transfer the carriers 4 carrying products at the left end of the front conveying path to the left end of the rear conveying path, and then the two carrying tracks on the right base 1 change positions repeatedly to transfer the empty carriers 4 at the right end of the rear conveying path to the right end of the front conveying path, so as to continuously circulate to connect the two conveying paths into a one-way conveying line in a ring shape (see Figure 5 , Figure 5 The different states of all the carriers 4 are superimposed, i.e., there are actually two empty positions for the carriers 4 on the entire conveying line);

[0064] When the watch cases 9 in the single tray on the loading plate 82 are all detected, the multiple suction nozzles 812 of the loading manipulator 81 suck the empty tray on the loading plate 82 and place the empty tray on the empty tray placing plate 83 to stack multiple empty trays.
