[0021] The following further describes the specific embodiments of the present utility model with reference to the accompanying drawings. It should be noted here that the description of these embodiments is for helping to understand the present utility model, but does not constitute a limitation to the present utility model. In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] As Figure 1-7 shown, an O-ring sleeving device includes an O-ring feeding module 1 and an O-ring clamping module 2; the O-ring clamping module 2 is located between the O-ring feeding module 1 and the base placing jig 3 to transfer the O-ring 130 of the O-ring feeding module 1 to the rotating shaft 110 of the base 100 located in the base placing jig 3;

[0023] The O-ring clamping module 2 includes a moving mechanism 21 and an expanding component 22. The expanding component 22 is arranged below the moving mechanism 21. The expanding component 22 includes a multi-jaw chuck 221 and a scraper 222. The scraper 222 is provided with a through hole 223. The multi-jaw chuck 221 includes a plurality of claws 225. The claws 225 movably pass through the through hole 223 from top to bottom.

[0024] In the O-ring device, the claws 225 of the multi-claw chuck 221 are inserted into the O-ring 130 located in the O-ring feeding module 1, and then the claws 225 are unfolded to open the O-ring 130, and then the O-ring 130 can be lifted and transferred to the rotating shaft 110 located in the base placement jig 3, and inserted into the rotating shaft 110. At this time, the claws 225 are retracted and the multi-claw chuck 221 moves upward, the scraper 222 is stationary relative to the base placement jig 3, and the claws 225 will move upward relative to the through hole 223 in the scraper 222, and the O-ring 130 located on the claws 225 will contact the bottom surface of the scraper 222, thereby detaching from the claws 225 and remaining in the rotating shaft 110, so as to realize the assembly of the O-ring 130. In this way, the feeding and ringing process can be automated, and the processing efficiency is improved compared with manual processing.

[0025] Preferably, Figure 4-7 As shown, the spreading assembly 22 further includes a lifting cylinder 226, the telescopic shaft of the lifting cylinder 226 faces the scraper 222, and the telescopic shaft of the lifting cylinder 226 is fixedly connected to the multi-claw chuck 221 to drive the claws 225 of the multi-claw chuck 221 to perform lifting motion in the through hole 223. By providing the lifting cylinder 226, the multi-claw chuck 221 can be driven to perform lifting motion relative to the scraper 222, so that the claws 225 of the multi-claw chuck 221 can perform lifting motion in the through hole 223.

[0026] Optional, such as Figure 5 and 6 As shown, the multi-claw chuck 221 includes a chuck driver 224 and four claws 225, and the four claws 225 are evenly distributed at the output end of the chuck driver 224, so that the four claws 225 simultaneously move toward or away from the center of the output end of the chuck driver 224. The chuck driver 224 is an existing structure, which can drive the four claws 225 to move toward or away from the center of its own output end at the same time, so as to realize the opening and closing of the claws 225, so as to prop up or put down the O-ring 130.

[0027] Specifically, Figure 4 and 7As shown, the moving mechanism 21 includes a transverse guide rail 211, a guide seat 212, and a longitudinal guide rail 213. The transverse guide rail 211 extends from the O-ring loading module 1 in the direction of the base placing jig 3. The guide seat 212 is slidably connected to the transverse guide rail 211. The longitudinal guide rail 213 is perpendicular to the transverse guide rail 211 and is disposed on the guide seat 212. The spreading assembly 22 is slidably connected to the longitudinal guide rail 213. Through the transverse guide rail 211 and the longitudinal guide rail 213, the translation and lifting of the spreading assembly 22 are realized, so as to achieve the purpose of transferring the O-ring 130 from the O-ring loading module 1 to the base placing jig 3.

[0028] Preferably, as Figure 3 shown, the O-ring loading module 1 includes a vibrating table 11, a loading guide rail 12, and a limit block 13. The loading guide rail 12 is disposed above the vibrating table 11. The limit block 13 is provided with a limit groove 14. The output end of the loading guide rail 12 is communicated with the limit groove 14, so that the O-ring clamping module 2 transfers the O-ring 130 located in the limit groove 14 to the base placing jig 3. By vibrating the loading guide rail 12 with the vibrating table 11, the O-rings 130 on the loading guide rail 12 move towards its output end, and only one O-ring 130 enters the limit groove 14 each time, thus facilitating the O-ring clamping module 2 to take out the O-ring 130 from the O-ring loading module 1.

[0029] It should be noted that, as Figure 3 shown, the O-ring loading module 1 further includes an opposed photoelectric switch 15. The emitting end and the receiving end of the opposed photoelectric switch 15 both face the limit groove 14. When an O-ring 130 enters the limit groove 14, the infrared ray emitted by the emitting end of the opposed photoelectric switch 15 will be blocked by the O-ring 130. If the receiving end cannot receive the infrared ray, it will prompt the upper computer that there is an O-ring 130 in the limit groove 14, and then drive the O-ring clamping module 2 to act.

[0030] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present invention, various changes, modifications, substitutions, and variations to these embodiments still fall within the protection scope of the present invention.
