[0002] During the manufacturing process of the motor stator, hairpin-shaped flat copper wires need to be clamped in the wire slots of the motor stator core. The lead wires of the clamped flat copper wires need to be tinned to improve their conductivity and welding performance, ensuring the stability and reliability of the motor in subsequent electrical connections.

[0003] At present, the tinning operation of the motor stator mainly relies on manual labor. The staff holds a soldering iron and tins the ends of the flat copper wire one by one. This tinning method has low work efficiency and large amount of manual labor. On the other hand, due to individual differences among the staff, the quality of the tinning of the ends of the flat copper wire cannot be guaranteed to be consistent. It is easy to have uneven tinning and later cause cold soldering problems, which affects the reliability of the electrical connection of the motor. Therefore, it is necessary to improve it.

A bracket 3 is installed on the work table 1 through the lifting and rotating mechanism. The bracket 3 is a plate-shaped body and is provided with a clearance hole 4. When working, the bracket 3 can lift the iron core of the motor stator, and the clearance hole 4 can make way for the flat copper wire lead-out line 24 in the iron core wire slot, thereby facilitating the subsequent tinning work of the flat copper wire lead-out line 24.

[0021] The lifting and rotating mechanism includes a lifting cylinder 5 and a rotating motor 6. The rotating motor 6 is fixedly installed on the bottom surface of the work table 1 through a motor mounting base 22. The transmission shaft of the rotating motor 6 extends to the top of the work table 1. The lifting cylinder 5 is fixedly installed on the transmission shaft of the rotating motor 6 extending above the work table 1. A positioning frame 7 is provided on the circumference of the cylinder body of the lifting cylinder 5. The positioning frame 7 is fixedly installed on the desktop of the work table 1. The positioning frame 7 and the cylinder body are movably connected by a bearing 8. When working, the positioning frame 7 is used to position the lifting cylinder 5 to prevent the lifting cylinder 5 from tilting during rotation.

[0022] The piston rod of the lifting cylinder 5 cannot rotate and can only move linearly. The piston rod of the lifting cylinder 5 is fixedly connected to the bracket 3. When working, the piston rod of the lifting cylinder 5 can drive the bracket 3 to rise or fall.

[0023] A water storage tray 2 is provided on the work table 1 on one side of the bracket 3. The water storage tray 2 is cylindrical. A limiting flange 9 is provided at the bottom of the water storage tray 2. The limiting flange 9 is fixedly connected to the work table 1 by bolts.

[0024] A tin stove assembly is provided on the work table 1 on the other side of the bracket 3. The tin stove assembly includes a tin stove body 10 and a tin scraper. The tin stove body 10 is a rectangular box-shaped body. The tin stove body 10 is a commercially available part. The tin stove body 10 can heat the tin block into tin water after being connected to an external power supply through a power cord. The tin stove body 10 is clamped on the work table 1 through a limit block 11. The limit block 11 is a right-angled rectangular block. The limit block 11 is fixed to the desktop of the work table 1 by bolts. When working, the limit block 11 forms a limit for the tin stove body 10.

[0025] A tin scraper is provided on the work table 1 on one side of the tin furnace body 10. The tin scraper includes an assembly plate 12 and a scraper 13. An assembly frame 14 is fixedly installed between the assembly plates 12. The assembly plate 12 is fixedly installed on the desktop of the work table 1. A clearance groove 15 is provided on the assembly frame 14. A slider 16 is provided in the clearance groove 15. When working, the slider 16 can slide along the axial direction of the clearance groove 15.

[0026] A rodless cylinder 17 is arranged between the assembly plate 12 below the slider 16, and the piston head of the rodless cylinder 17 is fixedly connected to the slider 16. A fixing frame 18 is fixedly mounted on the slider 16, and a cross bar 19 is fixedly mounted on the fixing frame 18. A scraper 13 is fixedly mounted on the cross bar 19. One end of the scraper 13 extends to the inner side of the tin furnace body 10. When working, the scraper 13 can remove oxides on the surface of the tin water in the tin furnace body 10.

[0027] A first in-position sensor 20 (model HLG103SJ) is mounted on the assembly plate 12 at one end of the assembly rack 14 , and a second in-position sensor 21 (model HLG103SJ) is mounted on the assembly plate 12 at one end of the assembly rack 14 .

[0028] The motor stator automatic tinning device is provided with a program controller (PLCS6-800), which is electrically connected to the lifting cylinder 5, the rotating motor 6, the rodless cylinder 17, the first in-position sensor 20 and the second in-position sensor 21. The program controller controls the lifting cylinder 5, the rotating motor 6, the rodless cylinder 17, the first in-position sensor 20 and the second in-position sensor 21 to move in sequence and in an orderly manner.

[0029] When the motor stator automatic tinning device is used, the staff first places the motor stator core 23 to be tinned on the bracket 3, and the bracket 3 lifts the motor stator core 23. The flat copper wire lead-out line 24 on the motor stator core 23 extends to the bottom of the makeshift hole 4. Then the rotating motor 6 is started by the program controller, and the transmission shaft of the rotating motor 6 drives the lifting cylinder 5, the bracket 3 and the motor stator core 23 to rotate as a whole, until the bracket 3 and the motor stator core 23 are moved to above the tin furnace body 10. The program controller controls the piston rod of the lifting cylinder 5 to retract, and the piston rod drives the bracket 3 and the motor stator to move downward as a whole, and the flat copper wire lead-out line 24 of the motor stator core 23 is aligned with the tin in the tin furnace body 10. After the water contacts, the program controller controls the piston rod of the lifting cylinder 5 to reset. At this time, the flat copper wire lead-out line 24 is separated from the tin water to complete the tinning. The program controller controls the transmission shaft of the rotating motor 6 to drive the lifting cylinder 5, the bracket 3 and the motor stator to rotate as a whole, so that the motor stator corresponds to the water storage tray 2. The program controller drives the piston rod of the lifting cylinder 5 to retract, so that the flat copper wire lead-out line 24 with tin on the motor stator core 23 contacts the cold water in the water storage tray 2, so that the tin on the flat copper wire lead-out line 24 cools and takes shape. The program controller drives the piston rod of the lifting cylinder 5 to reset, thereby completing the tinning of the flat copper wire lead-out line 24. Then the tinned motor stator is manually removed and replaced with the next motor stator core 23 to be tinned.

[0030] When the flat copper wire lead-out line 24 of the motor stator enters the water storage tray 2 for cooling, the program controller controls the piston of the rodless cylinder 17 to drive the slider 16, the fixing frame 18, the cross bar 19 and the scraper 13 to slide from the right end of the tin furnace body 10 to the left end. When the slider 16 slides to the left end, the slider 16 contacts the first in-position sensor 20. The first in-position sensor 20 transmits the in-position signal of the slider 16 to the program controller. The program controller controls the piston of the rodless cylinder 17 to reset. The piston drives the slider 16, the fixing frame 18, the cross bar 19 and the scraper 13 to slide from the left end of the tin furnace body 10 to At the right end, when the slider 16 slides to the right end, the slider 16 contacts the second in-position sensor 21, and the second in-position sensor 21 transmits the in-position signal of the slider 16 to the program controller. The program controller controls the piston of the rodless cylinder 17 to stop and wait for the next tin scraping operation. When the piston drives the slider 16, the fixed frame 18, the cross bar 19 and the scraper 13, and slides from the right end of the tin furnace body 10 to the left end, and then from the left end to the right end, the scraper 13 scrapes the oxide layer on the surface of the tin water in the tin furnace body 10 to one end of the tin furnace body 10, so as to facilitate the next tinning operation.

[0031] The motor stator automatic tinning device effectively reduces manual labor, improves tinning work efficiency, and ensures good consistency of tinning quality, avoiding problems such as uneven tinning and cold soldering.
