It can shield and protect the pallet discharge storage machine 3, the feeding elevator 4 and the discharge conveyor belt 14, so as to avoid injury to the operators during the operation of the equipment and improve safety.

[0036] like Figure 3 As shown, in this embodiment of the present invention, the pallet discharge storage machine 3 and the feeding elevator 4 are respectively provided with a support frame 24, a lifting support 25, a drive mechanism 26 and a conveyor table 1. The conveyor table 1 is installed on the upper side of the support frame 24 and is located on the upper side of the bottom frame 16. A set of lifting supports 25 is installed on the inner side of the support frame 24 of the pallet discharge storage machine 3. Multiple sets of lifting supports 25 are installed on the inner side of the support frame 24 of the feeding elevator 4. The drive mechanism 26 is installed on the outer side of the support frame 24 and is connected to the lifting support 25 through a lifting transmission mechanism.

[0037] In this embodiment of the invention, the feeding elevator 4 is used to place pallets 21 supporting product workpieces 22. Multiple pallets 21 are placed on lifting supports 25 at different heights. The lifting supports 25 are raised and lowered by the drive mechanism 26. The pallets 21 are transported to the upper side of the bottom frame 16 by the conveyor table 1, making it easy for the six-axis robot 5 to pick them up. The pallet unloading and storage machine 3 is used to store empty pallets 21. Empty pallets 21 are transported to the support frame 24 of the pallet unloading and storage machine 3 by the conveyor table 1 on the upper side of the pallet unloading and storage machine 3. The drive mechanism 26 of the unloading and storage machine 3 drives the lifting supports 25 to descend, making it easy to stack the pallets 21.

[0038] like Figure 4 As shown, in this embodiment of the present invention, the lower end of the rotary table 17 is fixed with a connecting shaft, and the lower end of the connecting shaft is connected to the output shaft of the rotary motor 28 through a coupling 27. The rotary motor 28 is fixed inside the bottom frame 16.

[0039] In this embodiment of the utility model, the rotary motor 28 drives the rotary table 17 to rotate, thereby enabling the positioning fixture 11 to switch between different work positions.

[0040] like Figure 5 As shown, the positioning fixture 11 in this embodiment of the present invention includes a workpiece placement seat 29 and a positioning cylinder 30, and a plurality of positioning cylinders 30 are provided on the side of the workpiece placement seat 29.

[0042] In use, this invention utilizes a test workpiece 9 pre-placed on the bottom frame 16 to test the overall equipment's operational status. The test workpiece 9 is a qualified electrode holder product. After the overall equipment is operating well, the six-axis robot 5 picks up the product workpiece 22 from the tray 21 and moves it to the underside of the vision component 6. The vision component 6 identifies the orientation of the terminal head of the product workpiece 22. Based on the identification information, the six-axis robot 5 rotates the product workpiece 22 to a suitable angle, places it in the first station, and locks it. The rotary table 17 rotates the product workpiece 22 to the second station. The six-axis robot 5 picks up the flexible flat cable 23 from the flexible vibrating plate 7 and places it in the second station, pressing it firmly against the upper end of the product workpiece 22. When picking up the flexible flat cable 23, the six-axis robot 5 only picks up the correctly oriented flexible flat cable 23 based on the detection information from the vision component 6. The rotary table 17 rotates the product workpiece 22 to the third station, where the electrode testing assembly 10 performs a downward contact power-on test. If the test fails, the rotary table 17 continuously rotates the defective product to the unloading module 2, which unloads the defective product onto the conveyor belt corresponding to the defective product collection box. If the test passes, the product proceeds to the fourth station for automatic soldering using the soldering machine 12. After soldering, the product rotates to the fifth station. The line scan assembly 13 performs soldering quality inspection. If the inspection fails, the rotary table 17 continuously rotates to the unloading module 2, which unloads the defective product onto the conveyor belt corresponding to the defective product collection box. If the inspection passes, the product rotates to the sixth station, where the unloading module 2 unloads it onto the discharge conveyor belt 14, which then transports it to the subsequent station, completing the entire process.
