Description

Technical Field

[0001] The utility model relates to the technical field of micro-motors, in particular to a sleeve pulling device. Background Art

[0002] In the structure of a micro-motor, iron cores are formed at both ends of the micro-motor, and sleeves are sleeved on the iron cores. After the iron cores go through the step of high-temperature coating, a coating layer will be wrapped on the iron cores. Then, the sleeves on both sides of the micro-motor need to be pulled off. However, after the high-temperature coating of the iron cores, the coating layer on the surface of the iron cores is not completely dry. If the iron cores are directly pulled out, the bonding part between the coating layer on the surface of the iron cores and the sleeves will peel off, resulting in the exposure of the iron cores and the dropping of the coating layer. Before manual pulling, the sleeves need to be rotated by a certain angle on the iron cores to separate the bonding part between the sleeves and the coating layer, and then the sleeves are taken out from the iron cores. However, the time consumed by manual rotation and pulling is relatively long, which will reduce the production efficiency. Summary of the Utility Model

[0024] Under the existing technology, there is a cylindrical iron gasket in the middle of the micro-motor. Cores are installed on both sides of the cylindrical iron gasket. During the process of removing the sleeve, after manually rotating the sleeve by hand, the sleeve needs to be removed from the core. The entire process of removing the sleeve needs to be completed manually, which is time-consuming and cannot keep up with the rhythm of the production line.

[0025] To solve the above problems, as Figures 1 to 4 shown, the present utility model provides a sleeve pulling device, which includes a table board 1, a feeding track 2 and a discharging track 3. The feeding track 2 and the discharging track 3 are inclined and fixed on the table board 1. A stopper 4 is rotatably installed at the high-position end of the discharging track 3. The cores 241 on both sides of the micro-motor 24 are in contact with the stopper 4. A lifting assembly is installed on the lower side of the low-position side of the feeding track 2. The lifting assembly is installed under the stopper 4. A magnet 5 is installed inside the lifting assembly. The magnet 5 adsorbs the micro-motor 24. A first cylinder 6 is installed under the lifting assembly. The first cylinder 6 pushes the lifting assembly to rise. The core 241 contacts the lower side of the stopper 4 and rotates. A bracket 8 is installed on the table board 1. An abutting member 9 is installed on the bracket 8. The lifting assembly and the abutting member 9 abut the micro-motor 24; Clamping members 10 are installed on both sides of the feeding track 2. The clamping members 10 can clamp the sleeve on the core 241. The clamping members 10 are rotatably installed on a rotary cylinder 11. A propulsion cylinder 12 pushes the rotary cylinder 11 to move along the axis of the core 241.

[0026] Projecting along a direction perpendicular to the table board 1, the feeding track 2 and the discharging track 3 are on the same straight line. The low-position end of the feeding track 2 is lower than the high-position end of the discharging track 3. Laps are formed on the feeding track 2 and the discharging track 3. The core 241 rolls and slides down on the laps to reach the designated position. The micro-motors 24 are sequentially placed on the feeding track 2. The micro-motors 24 roll obliquely downward. The foremost micro-motor 24 is directly adsorbed and fixed by the magnet 5 of the lifting assembly. Then the lifting assembly rises. During the rising process, the stopper 4 will be pushed to rotate upward. Then the stopper 4 resets and receives the micro-motor 24 that is about to fall. Finally, the micro-motor 24 rises and abuts against the abutting member 9. At this time, the axis of the core 241 of the micro-motor 24 coincides with the rotation axis of the rotary cylinder 11. Then the propulsion cylinder 12 pushes the rotary cylinder 11 to approach the core 241. The clamping jaws on the clamping member 10 grab the sleeve. Then the rotary cylinder 11 rotates. Then the propulsion cylinder 12 moves in the reverse direction. The clamping member 10 pulls out the sleeve from the core 241. The lifting assembly descends. Since the gap between the stoppers 4 is smaller than the micro-motor 24, the core 241 of the micro-motor 24 overlaps on the stoppers 4, and the micro-motor 24 will roll along the stoppers 4 onto the discharging track 3, completing the removal of the sleeve. The above process does not require manual intervention, can improve the production process, accelerate the speed of removing the sleeve, and improve production efficiency.

[0027] A first cylinder 6 is installed on the lower side of the table board 1. The first cylinder 6 pushes the lifting rod 7 to move. The lifting rod 7 is inserted into the table board 1. There is a lifting assembly at the upper end of the lifting rod 7. Every time the first cylinder 6 rises, it will transport a group of micro-motors 24 upward. The stopper 4 can separate the micro-motors 24 from the lifting assembly during the process of the first cylinder 6 driving the lifting rod 7 to fall. The micro-motors 24 are conveyed upward through the lifting rod 7 in the first cylinder 6, replacing manual extraction and improving the processing efficiency.

[0028] The lifting assembly of the present utility model includes a pushing plate 13. A notch is formed on the pushing plate 13. The notch is arranged at the low-position end of the feeding track 2. The micro-motors 24 roll along the feeding track 2 and fall into the notch. A magnet 5 is installed at the bottom of the notch. The micro-motors 24 are finally fixed by the magnet 5 to prevent falling. When the micro-motors 24 fall back after being pulled out of the sleeves, the stopper 4 will separate the micro-motors 24 from the magnet 5, causing the micro-motors 24 to roll along the discharging track 3.

[0029] Baffles 14 are installed on both sides of the feeding track 2 near the low-position end. The iron cores 241 are lapped on the baffles 14. A protrusion 141 is formed near the low-position end of the baffle 14. The iron cores 241 abut against the protrusion 141. The pushing plate 13 is installed in the gap between the baffles 14. The protrusion 141 can prevent the micro-motors 24 rolling along the feeding track 2 from falling out of the feeding track 2. The micro-motors 24 are arranged in sequence on the inclined feeding track 2. Every time the pushing plate 13 reciprocates up and down, a new micro-motor 24 can roll into the notch, realizing automatic feeding.

[0030] An abutting cylinder 15 is installed on the bracket 8. The abutting cylinder 15 pushes the abutting rod 16 to slide along the axis. An abutting member 9 is installed at the lower end of the abutting rod 16. Setting the abutting cylinder 15 can adjust the position where the abutting member 9 contacts the lifting rod 7, and further can adjust the height of the micro-motor 24 when being pulled out of the sleeve, making the sleeve-pulling device of the present utility model more versatile.

[0031] Waste boxes 17 are installed on both sides of the feeding track 2. The waste boxes 17 can collect the sleeves. The waste boxes 17 are installed under the clamping members 10. After the sleeves on the iron cores 241 are pulled out, the sleeves can fall from the clamping members 10 into the waste boxes 17 below. The sleeves can fall into the waste boxes 17, realizing the collection of the sleeves and preventing the sleeves from falling randomly.

[0032] A blowing pipe 18 is also installed on the bracket 8. One end of the blowing pipe 18 is connected to an external air source. The other end of the blowing pipe 18 faces the clamping members 10. The blowing pipe 18 is installed above the waste boxes 17. By setting the blowing pipe 18, the sleeves on the clamping members 10 can be accurately blown into the waste boxes 17, preventing the sleeves from getting stuck in the clamping members 10.

[0033] A pressing plate 19 is installed on the feeding track 2. The micro-motor 24 rolls along the feeding track 2 and enters between the pressing plate 19 and the feeding track 2. After the micro-motor 24 is placed into the feeding track 2 by setting the pressing plate 19, multiple groups of micro-motors 24 are arranged in sequence in the feeding track 2. In order to prevent the micro-motor 24 from detaching from the feeding track 2, a pressing plate 19 is installed on the upper side of the feeding track 2, which enables the micro-motor to be lifted by the lifting assembly in sequence to complete the step of pulling out the sleeve.

[0034] A fixing plate 20 is installed on the rotating cylinder 11. The fixing plate 20 is slidably installed on the guide rail 21. A limiting member 22 is installed on the guide rail 21, and a buffer 23 is installed on the limiting member 22. The buffer 23 abuts against the fixing plate 20. The buffer 23 can limit the movement of the rotating cylinder 11 pushed by the propulsion cylinder 12, so that the clamping member 10 on the rotating cylinder 11 can stay at the set position, which is convenient for the clamping member 10 to directly clamp the sleeve on the iron core 241.

[0035] Obviously, the above-mentioned embodiments of the present invention are only examples for clearly explaining the present invention, and are not intended to limit the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
