At present, the output of new energy vehicles is increasing, the cycle time for electric drive system testing is getting shorter and shorter, the demand for unmanned factories is getting higher and higher, and the pre-storage time requirement for the loading method of the electric drive system is getting longer and longer.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the present invention provides a five-in-one electric drive single-layer feeding system with a reflux function, which has the following beneficial effects: the five-in-one electric drive single-layer feeding system with a reflux function realizes the loading and unloading of the electric drive system on the same layer of the line, ensures a sufficient amount of electric drive pre-stored, reduces the loading frequency, improves the effective utilization rate of the equipment, avoids the shortcomings of the previous loading and transfer trolley solution, and solves the pain points of the industry. The pallet moves on the position of the loading and unloading transmission roller line. When it moves to the position of the vision-guided robot module, the vision-guided robot module sucks the product inside the discharge seat to the position on the secondary positioning module for secondary positioning operation. After the position is corrected, the vision-guided robot module sucks the product to the top of the feeding mechanism of the ring main line, and the product passes through the feeding mechanism on the ring main line. The unqualified products are tested through the detection seat. After the test is completed, the unqualified products are pushed through the position of the unqualified product pushing mechanism and fall into the material box position. The qualified products continue to move forward and return to the original position. The visually guided robot module returns the qualified products on the feeding mechanism of the ring main line to the position of the unloading seat. Because unqualified products are pushed away, the position of the unloading seat will be vacant. The unloading seat on the pallet needs to be full of material before it can be discharged from the position of the loading and unloading transmission roller line. When the product at the unloading seat position is not full, the pallet is sent to the position of the loading and unloading pallet switching roller line for storage until the subsequent products fill the position of the unloading seat. After the unloading seat on the pallet is full of material, the pallet flows out from the position of the loading and unloading transmission roller line. The entire electric drive single-layer feeding system has a simple structure, is easy to operate, and has better effect than the traditional method. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Working principle: The present invention includes a loading and unloading transmission roller line 1, a loading and unloading pallet switching roller line 2, a vision-guided robot module 3, a secondary positioning module 4, a ring-type main line loading mechanism 5, a pallet 6, a discharge seat 7, a switching mechanism 8, a detection seat 9, a protective fence 10, a door frame 11, a non-conforming product pushing mechanism 12, a roller 13, a driving machine 14, a roller 15, a detection circuit board 16, a detector 17, a detection rod 18, a robotic arm 19, a rotating seat 20, a rotating arm 21, a suction seat 22, a pushing plate 23, a protective pad 24, a telescopic rod 25, and a control seat 26. , product qualification distinction module 27, display module 28, central processing module 29, pushing mechanism module 30, pushing control module 31, relay module 32, battery module 33, product size detection module 34, electric drive system test module 35. When in use, the tray 6 moves at the position on the unloading and loading transmission roller line 1. When it moves to the position of the vision-guided robot module 3, the vision-guided robot module 3 sucks the product located inside the unloading seat 7 to the position on the secondary positioning module 4 for secondary positioning operation. After the position is corrected, the tray 6 moves to the position on the secondary positioning module 4. The vision-guided robot module 3 sucks the product onto the top of the feeding mechanism 5 on the ring main line. The product is inspected by the detection seat 9 on the feeding mechanism 5 on the ring main line.

When the product at the discharge seat 7 position is not full, the tray 6 is sent to the position of the loading and unloading tray switching roller line 2 for storage until the subsequent products fill the position of the discharge seat 7. After the discharge seat 7 on the tray 6 is full, the tray 6 flows out from the position of the loading and unloading conveyor roller line 1, realizing the loading and unloading of the electric drive system on the same layer of the line, ensuring sufficient electric drive pre-stored quantity, reducing the loading frequency, improving the effective utilization rate of the equipment, avoiding the shortcomings of the previous loading and transfer trolley solution, and solving the industry pain points.
