[0014] The present invention also discloses a production method of a stator and rotor core automatic stacking device, which specifically comprises the following steps:

[0015] Step 1: Before the punch stacks the stator and rotor sheets, the winding machines on both sides work simultaneously to release and wind the two sides of the roll film, so that different parts of the roll film surface cover the surface of the punch, and the connecting groove on the roll film is aligned with the through hole axis on the punch, and then the glue spraying nozzle inside the through hole on the punch can spray glue and stack, and the splashed glue adheres to the surface of the roll film;

[0016] Step 2: On the basis of step 1, when the roll film carrying glue moves to the inside of the flat tube, the heating fan starts to work, and the air circulates through the trough, the inner cavity, the pores and the partition. When the air flows, the hot end of the semiconductor refrigeration plate heats the air inside the inner cavity so that the hot air dries the glue on the roll film. Then, along with the movement, the cold end of the semiconductor refrigeration plate cools it down by contacting with the roll film. At the same time, when one side of the roll film is moved out through one end of the flat tube, the scraper scrapes off the dried glue on the surface of the roll film. The scraped glue waste is sucked into the inner cavity by the flowing air through the material trough, and then the waste is filtered and blocked by the filter plate, and then accumulates on one side of the inside of the material tube and on the outer surface of the baffle. When the accumulation of waste increases, the gravity of the waste is greater than the elastic force of the torsion spring, and the waste is pressed down by gravity to rotate the baffle to fall into the other side of the inside of the material tube, and then stored and collected through the material tube. In this process, the filter holes on the material tube can balance the air pressure inside the material tube and the inner cavity to avoid unstable air pressure inside the material tube, which causes the waste to fly inside the material tube;

[0017] Step three: On the basis of step one, when the replacement part of the roll film covers the surface of the punch, the telescopic cylinder and the linear motor work in sequence, so that the support drives the sleeve to cover the outside of the through hole on the punch, and makes the sleeve contact with the roll film, and then through the action of the circulation pipe, spring pipe, groove and grille groove, the heating fan works to make the air circulate in the inner cavity and the through hole to dry the glue attached to the inside of the through hole. After the drying is completed, the driving motor drives the sleeve to rotate, and through the connection between the slider and the slide groove, the slide tube drives the scraper to rotate with it, and when the slide tube rotates, the sliding wedge is acted on by centrifugal force to move inside the slide groove, and through the mutual contact with the fixed wedge, the sliding wedge drives the sliding tube and the scraper to rise through the spring rod, so that the scraper fits with the inside of the through hole, thereby scraping off the attached glue, and the scraped waste enters the inner cavity through the circulation of air.

[0018] Beneficial Effects

[0019] The present invention provides a device and a production method for automatically stacking stator and rotor cores. Compared with the prior art, it has the following beneficial effects:

[0020] (1) By setting up an anti-sticking component and using a roll film to cover the surface of the punch, the splashed glue can be prevented from adhering to the surface of the equipment. By winding the roll film, the problem of splashed glue on the outside of the punch can be quickly solved. At the same time, by drying and scraping it off, the roll film can be recycled to improve the stacking effect of the device.

[0021] (2) By setting up a collection assembly, the scraped glue waste can be filtered and collected using a filter plate and a material pipe, and through the action of gravity and the elastic force of the torsion spring, the baffle can close the inside of the material pipe to improve the waste collection effect.

[0022] (3) By setting up a scraper assembly and using a driving motor to drive the sleeve to rotate, the scraper bar can rotate inside the through hole to scrape off the glue attached to the inside of the through hole. At the same time, the movement of the telescopic cylinder and the linear motor can facilitate the connection between the scraper bar and the through hole, as well as the storage to avoid affecting the movement of the punch.

[0023] (4) By providing an adapter unit and utilizing the contact between the fixed wedge and the sliding wedge, during the cleaning process, the slider can drive the scraper bar to rise and scrape the material through the sliding tube, thereby controlling whether the scraper bar contacts the through hole, thereby facilitating the drying of the glue inside the through hole and the scraping of the dried glue.

[0024] (5) By setting up a processing unit and utilizing the connection between the grille slot and the groove, air circulation is facilitated when the sleeve rotates. At the same time, the glue can be dried and the glue waste can be adsorbed and collected by circulating air in the inner cavity and the through hole. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] The present invention also discloses a production method of a stator and rotor core automatic stacking device, which specifically comprises the following steps:

[0055] Step 1: Before the punch 1 stacks the stator and rotor sheets, the winding machines 4 on both sides work simultaneously to release and wind the two sides of the roll film 2, so that different parts of the surface of the roll film 2 cover the surface of the punch 1, and the connecting groove 3 on the roll film 2 is aligned with the through hole axis on the punch 1, and then the glue spraying nozzle inside the through hole on the punch 1 can spray glue and stack, and the splashed glue adheres to the surface of the roll film 2;

[0056] Step 2: On the basis of step 1, when the roll film 2 carrying the glue moves to the inside of the flat tube 5, the heating fan 13 starts working, and the air circulates through the trough 10, the inner cavity 9, the air hole 11 and the partition 15. When the air flows, the hot end of the semiconductor refrigeration plate 14 heats the air inside the inner cavity 9 so that the hot air dries the glue on the roll film 2. Then, along with the movement, the cold end of the semiconductor refrigeration plate 14 contacts the roll film 2 to cool it down. At the same time, when one side of the roll film 2 is moved out through one end of the flat tube 5, the scraper 12 scrapes off the dried glue on the surface of the roll film 2. The glue waste is sucked into the inner cavity 9 by the flowing air through the material trough 10, and then the waste is filtered and blocked by the filter plate 72, and then accumulated on one side of the inside of the material pipe 71, and accumulated on the outer surface of the baffle 74. When the accumulation of waste increases, the gravity of the waste is greater than the elastic force of the torsion spring 77, and the waste is pressed down by gravity to rotate the baffle 74 to fall into the other side of the inside of the material pipe 71, and then stored and collected through the material pipe 71. In this process, the filter hole 73 on the material pipe 71 can balance the air pressure inside the material pipe 71 and the inner cavity 9, so as to avoid unstable air pressure inside the material pipe 71, which causes the waste to fly inside the material pipe 71;

[0057] Step 3: On the basis of step 1, when the film roll 2 changes its position to cover the surface of the punch 1, the telescopic cylinder 88 and the linear motor 89 work in sequence, so that the support 81 drives the sleeve 83 to cover the outside of the through hole on the punch 1, and the sleeve 83 contacts the film roll 2, and then through the circulation pipe 876, the spring tube 875, the groove 872 and the grille groove 873, the heating fan 13 works to make the air circulate in the inner cavity 9 and the through hole to dry the glue attached to the inside of the through hole.
