The first conveying module 22 is arranged on the side of the feeding unit 2 close to the conveying unit 5, and the second conveying module is arranged on the side of the feeding unit 2 away from the conveying unit 5. The first conveying module 22 and the second conveying module are parallel to each other and the conveying directions of the two modules are opposite. The first conveying module 22 is used to receive the product to be tested 100 transferred by the conveying unit 5, and the second conveying module is used to receive the empty tray 1 transferred by the conveying unit 5 after the unloading unit 4 completes unloading. Figures 10-13 ​As shown, the conveying assembly includes a first conveying belt 51, a second conveying belt 52, a blocking cylinder 53 and a jacking assembly 54, the first conveying belt 51 is located above the second conveying belt 52, and the first conveying belt 51 and the second conveying belt 52 are both arranged in the first direction. Specifically, the first conveying belt 51 conveys the tray 1 carrying the products to be tested from the feeding unit 2 to the discharging unit 4, and the first conveying belt 51 of the conveying assembly close to the feeding unit 2 is connected to the first conveying module 22 away from one end of the first lifting assembly 28; the second conveying belt conveys the empty tray 1 from the discharging unit 4 to the feeding unit 2, and the second conveying belt 52 of the conveying assembly close to the feeding unit 2 is connected to the second conveying module away from one end of the first lifting assembly 28.

The jacking assembly 54 is arranged between the two single bodies on the two opposite sides of the conveying assembly, has the functions of jacking and rotating around the Z axis, and is used for conveying the tray 1 into the single body, so as to detect the products to be tested in the jigs on the tray 1. When there is no detection requirement, the jacking assembly 54 is located below the first conveying belt 51, when the tray 1 is blocked by the blocking cylinder 53 and stays at the corresponding position waiting for detection, the jacking assembly 54 starts to jack up the tray 1 to the corresponding position, and then the Z axis rotates to rotate the tray 1 by 90° (conveyed to the left single body and rotated counterclockwise by 90°, conveyed to the right single body and rotated clockwise by 90°), adjusts the products to be tested to the required direction for testing, and then transfers the tray 1 to the corresponding single body. The tray 1 enters the single body, and the single body simultaneously detects the products to be tested in each jig. Specifically, the upper surface of the jacking assembly 54 is also provided with a conveying belt (not shown in the figure), which can rotate with the rotation of the jacking assembly 54, when the jacking assembly 54 conveys the tray 1 to the position corresponding to the single body, rotates the tray 1, and then the conveying belt starts to transfer the tray 1 to the direction close to the single body, so that the tray 1 can smoothly enter the single body.

[0090] In a specific embodiment, the monomer is provided with a test port (not shown in the figure) near one side of the conveying assembly, and the tray carrying the product enters and exits the monomer through the test port for testing. The conveying assembly further comprises a side blocking flap 55 corresponding to the monomer, which is located on the side of the conveying assembly away from the monomer corresponding to the side blocking flap 55. When the tray is discharged from the monomer after testing is completed, the corresponding side blocking flap 55 is flipped up to limit the tray 1, preventing the tray 1 from falling. When the tray 1 returns to the jacking assembly 54, the jacking assembly 54 rotates to reset the tray 1 to the angle during conveying, and then the jacking assembly 54 lowers the tray 1 back onto the first conveying belt 51. The blocking cylinder 53 is retracted, and the first conveying belt 51 is started to convey the tray 1 carrying the tested product to the discharging unit 4.

[0091] In an optional example, the conveying unit 5 is provided with three sets of conveying assemblies, namely the first conveying assembly 5A, the second conveying assembly 5B, and the third conveying assembly 5C, which are arranged along the first direction and the tray 1 can be transferred between adjacent conveying assemblies. Correspondingly, the testing unit 3 comprises six monomers, namely the first monomer 31, the second monomer 32, the third monomer 33, the fourth monomer 34, the fifth monomer 35, and the sixth monomer 36.
