[0028] like Figure 1 As shown, Figure 1 The overall cross-sectional structure schematic diagram of the hot-melt device for producing motor rotors of the present invention is shown;

[0029] A welding mechanism 2 is provided at the top of the outer wall of the chassis 1. The welding mechanism 2 includes a first pneumatic rod 21 and an upper welding joint 22. The upper welding joint 22 is provided at the bottom end of the first pneumatic rod 21.

[0030] A lower welding seat 3 is provided at the bottom of the upper welding head 22, a cleaning mechanism 5 is installed inside the lower welding seat 3, and the lower welding seat 3 is inserted on the fixing seat 4;

[0031] A slide 7 is provided on the left side of the chassis 1, and a motor rotor 6 is placed on the top of the slide 7. The motor rotor 6 can slide horizontally on the slide 7 to facilitate processing operations.

[0032] When the present invention is implemented:

[0033] Assembly and loading: Put the conductive sleeve 9 on the end of the lead 61, move the motor rotor 6, and the motor rotor 6 moves on the slide 7, and adjust the position of the conductive sleeve 9 so that the conductive sleeve 9 is inserted into the installation groove 31. When the end surface of the conductive sleeve 9 contacts the scraper 52 and the conductive terminal 91 extends out of the through hole 521, the conductive sleeve 9 is in place;

[0034] Air replacement: The nitrogen storage tank in the air supply box 81 releases nitrogen, a part of which is quickly released to the air inlet 42, and then discharged through the air outlet 43, quickly replacing the air in the fixed groove 41, so that the root of the lower welding seat 3 is in a nitrogen environment, and another part of the nitrogen is quickly released to the shunt pipe 82, and then discharged downward through the exhaust ring 83, so that the leaking part of the lower welding seat 3 is completely in a nitrogen environment;

[0036] Subsequent cleaning: After the welding is completed, the upper welding joint 22 stops heating, the conductive sleeve 9 is removed, the conductive sleeve 9 leaves the lower welding seat 3, and the conductive terminal 91 leaves the through hole 521; the first pneumatic rod 21 drives the upper welding joint 22 to move downward, so that the upper welding joint 22 enters downward into the grinding groove 32, and then the rotating motor 10 drives the fixing seat 4 and the lower welding seat 3 to rotate synchronously, and the grinding particles on the inner wall of the grinding groove 32 can grind the outer wall of the upper welding joint 22 to eliminate the residue attached to the outer wall of the upper welding joint 22. After high-speed grinding for 30 seconds, the rotating motor stops working, and the second pneumatic rod 51 drives the upper welding joint 22 to reset upward; then the second pneumatic rod 51 drives the scraper 52 to move along the installation groove 31, and the scraper 52 can scrape off the residue on the inner wall of the installation groove 31. After scraping, the second pneumatic rod 51 is reset;

[0037] During the above cleaning process, the nitrogen diverter valve at the air inlet 42 is closed, and the valve body on the diverter pipe 82 is kept open, so that the nitrogen discharged from the exhaust ring 83 can quickly blow away the waste chips being cleaned.

[0038] Through this embodiment, oxides can be effectively eliminated from multiple angles before and after processing, thereby improving the welding effect.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
