[0049] Example 2

[0050] The automatic labeling and testing equipment described in this embodiment has the same structure as that in embodiment 1, except that Figure 9 The device shown also includes a set of positioning mechanisms 58 , which are installed on the rotating workbench 51 .

[0051] like Figure 9 The positioning mechanism 58 shown includes a positioning mounting frame 581, a positioning adapter frame 582, a positioning assembly 583 and a positioning drive cylinder 584.

[0055] The working principle of the automated labeling and testing equipment described in this embodiment is as follows:

[0056] First, the product is transported to the designated location via the loading conveyor line 54. The detection and grabbing mechanism 55 grabs the product and places it on the positioning carrier 511 of the rotary table 51. After the first detection mechanism 52 detects that there is a product on the positioning carrier 511, the rotary table 51 starts to rotate, driving the positioning carrier 511 with the product to rotate to the labeling station.

[0057] The positioning mechanism 58 presses down on the product; the labeling device 4 starts working, the rotary drive motor 4121 starts to rotate, driving the connecting assembly 4122 to rotate. Since one end of the connecting assembly 4122 is located in the drive slot of the drive plate 413, the connecting assembly 4122 will drive the drive plate 413 to move together during its rotation. The labeling mounting plate 421 is connected to the drive plate 413, and the labeling mounting plate 421 is slidably connected to the linear slide rail. Therefore, the drive plate 413 will drive the labeling mounting plate 421 and the labeling nozzle module 423 to move up and down. After the labeling nozzle module 423 sucks the label, the labeling rotary drive cylinder 422 will drive the labeling nozzle module 423 to rotate and apply the label to the product;

[0058] After labeling is completed, the rotating workbench 51 drives the labeled product to continue rotating until it reaches the second inspection station. The positioning mechanism 58 positions the product. The detection drive cylinder 532 in the second inspection mechanism 53 drives the test tongue 534 to insert into the product. The resistance tester test head 533 tests the resistance of the product and stores the test data in a designated location.

[0059] The rotating workbench 51 drives the inspected product to rotate to the scanning station, where the scanning device 56 scans the product. If the product is qualified after scanning, the inspection and grasping mechanism 55 grabs the product and puts it on the unloading conveyor 57, and then conveys it to the designated location through the unloading conveyor 57.

[0060] If the inspected product is defective, it will be grabbed by the defective product unloading mechanism 59 and placed in the defective product storage box.

[0061] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements can be made without departing from the principles of the present invention. These improvements should also be regarded as within the scope of protection of the present invention.
