[0075] The pull spring 210 is fixedly connected with the first connecting piece 233a. The lower part of the spring telescopic rod 240 is fixed on the first connecting piece 233a. Specifically, the first connecting piece 233a is provided with a vertically arranged threaded through hole, and the lower part of the mounting pipe body 241 is provided with a first external thread segment, which is screw-connected with the threaded through hole.

[0079] The riveting device 400 includes an anchoring table 410 fixed on the workbench 100, a vertical shaft 420 vertically and slidingly connected to the anchoring table 410, and a driving lifting mechanism 430 for driving the vertical shaft 420 to lift. The lower part of the vertical shaft 420 is slidingly inserted into the main hole section 251. The middle part of the vertical shaft 420 has an outer convex ring 421 located directly above the spring telescopic rod 240. A hemispherical groove is formed in the lower end of the vertical shaft 420 for pressing the rivet. The driving lifting mechanism 430 is in transmission connection with the vertical shaft 420. It should be noted that the driving lifting mechanism 430 is of a conventional structure, and the transmission connection structure between the driving lifting mechanism 430 and the vertical shaft 420 is also of a conventional structure, which will not be described in detail.

[0080] As a preferred technical solution, the hole bottom of the mounting hole 234 is in communication with one end of the countersunk head section 252 close to the outer convex ring 421, and the magnet 231 has an abutting portion located on the side of the countersunk head section 252 close to the outer convex ring 421. The lower end of the abutting portion is flush with the one end of the countersunk head section 252 close to the outer convex ring 421, thereby shortening the distance between the magnet 231 and the countersunk head section 252, and facilitating the magnet 231 to adsorb the gasket 999 onto the countersunk head section 252.

[0081] The gasket feeding set 300 comprises a support base 310, a discharge disc 320, a horizontal slide rail 330, a feeding base 340 and a driving motor 350. The support base 310 is fixed on the workbench 100; the discharge disc 320 and the horizontal slide rail 330 are fixed on the support base 310 respectively, the lower end of the discharge disc 320 is provided with a discharge through hole, the feeding base 340 is horizontally slidably connected to the horizontal slide rail 330, specifically, the feeding base 340 is horizontally slidably connected to the horizontal slide rail 330 in the direction of approaching or moving away from the counterbore 250, the upper end of the feeding base 340 is provided with a receiving groove for receiving the gasket 999 falling from the discharge through hole; the feeding base 340 is located below the discharge disc 320, preferably, the upper end surface of the feeding base 340 is always attached to the lower end surface of the discharge disc 320.

[0082] For the convenience of description, the movement of the feeding base 340 in the direction of approaching the counterbore 250 is defined as positive movement, and the movement of the feeding base 340 in the direction of moving away from the counterbore 250 is defined as reverse movement.

[0083] The countersunk head section 252, the discharge through hole and the receiving groove are located in the same vertical plane, and the discharge through hole is located on the side of the countersunk head section 252 away from the magnet 231. For the convenience of description, the vertical plane where the countersunk head section 252, the discharge through hole and the receiving groove are located is defined as the first plane.

[0084] The horizontal slide rail 330 is arranged in parallel with the first plane or located in the first plane, in this embodiment, the horizontal slide rail 330 is arranged in parallel with the first plane. The movement path of the receiving groove passes through directly below the countersunk head section 252 and the discharge through hole, so that after the receiving groove receives the gasket 999 from below the discharge through hole, it can move in the direction of approaching the countersunk head section 252 and send the gasket 999 to the lower side of the countersunk head section 252.

[0085] Before use, the magnet 231 with appropriate magnetic strength is selected to enable the gasket 999 to be attracted into the countersunk head section 252, it should be noted that when the receiving groove receives the gasket 999 and moves directly below the countersunk head section 252, the vertical component of the magnetic force of the magnet 231 on the gasket 999 should be greater than the gravity of the gasket 999 to ensure that the gasket 999 can be attracted.

[0086] If the magnet 231 is arranged at the center of the counterbore 250, when the gasket 999 is attracted to the magnet 231 before reaching the position directly below the counterbore section 252 of the counterbore 250, the distance between the gasket 999 after being attracted and the inner wall of the side of the counterbore section 252 close to the magnet 231 is relatively large, and thus the position error of the gasket 999 after being attracted is relatively large. By arranging the magnet 231 at one side of the counterbore 250 and conveying the gasket 999 from the side of the counterbore 250 away from the magnet 231 to the opposite side, when the gasket 999 is attracted to the magnet 231 before reaching the position directly below the counterbore section 252 of the counterbore 250, the proportion of the horizontal component of the magnetic attraction force of the magnet 231 is relatively large, which is conducive to reducing the distance between the gasket 999 after being attracted and the inner wall of the side of the counterbore section 252 close to the magnet 231, and thus is conducive to reducing the position error of the gasket 999 after being attracted.

[0087] The shell of the driving motor 350 is fixed on the workbench 100, the output shaft of the driving motor 350 is in transmission connection with the feeding seat 340, specifically, the feeding seat 340 has a horizontally arranged rack; the output shaft of the driving motor 350 has a gear; the gear is in meshing connection with the rack. It should be noted that the driving motor 350 is a step motor or a servo motor, and in the embodiment, the driving motor 350 is a step motor.

[0088] Before use, the forward rotation stroke and the reverse rotation stroke of the driving motor 350 are preset, wherein the value of the forward rotation stroke and the value of the reverse rotation stroke are the same, and the forward rotation stroke is not less than the horizontal distance between the counterbore section 252 and the discharge through hole. It should be noted that the forward rotation stroke refers to the stroke of the driving motor 350 driving the feeding seat 340 to move forward, and the reverse rotation stroke refers to the stroke of the driving motor 350 driving the feeding seat 340 to move reversely. In the embodiment, the forward rotation stroke is equal to the horizontal distance between the counterbore section 252 and the discharge through hole, and the reverse rotation stroke is equal to the horizontal distance between the counterbore section 252 and the discharge through hole. The initial position of the receiving groove is arranged directly below the discharge through hole. When the outer convex ring 421 enters the sensing range of the first inductor 500 in the manner mentioned below, the driving motor 350 drives the feeding seat 340 to move forward, and the stroke of the feeding seat 340 moving forward is the forward rotation stroke, and then the driving motor 350 drives the feeding seat 340 to move reversely, and the stroke of the feeding seat 340 moving reversely is the reverse rotation stroke.

[0089] The discharge tray 320 comprises a tray body 321 fixed on the support base 310, a tray cover 322 installed on the upper end of the tray body 321, and a discharge motor 323 installed on the upper end of the tray cover 322; the tray cover 322 is provided with a rotating hole, and the output shaft of the discharge motor 323 vertically penetrates the rotating hole; the tray body 321 is provided with a rotating brush 324, and the rotating brush 324 comprises a brush handle and a brush head; the brush handle is coaxially arranged with the output shaft of the discharge motor 323, the upper end of the brush handle is fixed on the lower end of the output shaft of the discharge motor 323, and the lower end of the brush handle is fixedly connected with the brush head; the lower end of the brush head is provided with vertically downward brush hairs.

[0090] In order to make the gasket 999 more easily enter the discharge hole, the upper end of the discharge hole is provided with a chamfer.

[0091] Before use, the gasket 999 is added into the tray body 321. During use, the discharge motor 323 drives the rotating brush 324 to rotate, and the brush hairs of the rotating brush 324 agitate the gasket 999 in the tray body 321, so that the gasket 999 enters the discharge hole.

[0092] The workbench 100 is further provided with a first inductor 500 and a second inductor 600. The first inductor 500 horizontally faces the vertical shaft 420, and the first inductor 500 is fixed on the lower side of the anchoring table 410 and used for inducting the outer convex ring 421. During use, the lifting mechanism 430 drives the vertical shaft 420 to move downward, the outer convex ring 421 gradually moves downward and leaves the inductive range of the first inductor 500, and when the lifting mechanism 430 drives the vertical shaft 420 to move upward, the outer convex ring 421 enters the inductive range of the first inductor 500, the driving motor 350 is triggered to drive the feeding seat 340 to convey the gasket 999.

[0093] The second inductor 600 is perpendicular to the first plane, and the second inductor 600 is fixed on the end of the horizontal slide rail 330 away from the counterbore 250 and used for inducting the feeding seat 340. When the second inductor 600 inducts the feeding seat 340, the driving motor 350 stops rotating, and the setting of the second inductor 600 is beneficial to ensuring that the feeding seat 340 will not slide out of the end of the horizontal slide rail 330 away from the counterbore 250.

[0094] The two ends of the horizontal slide rail 330 are further provided with limiting pieces for preventing the feeding seat 340 from sliding out of the horizontal slide rail 330.

[0095] Before first use, the pressure regulating bolt 244 is rotated first, so that the initial elastic force of the first spring 242 is greater than the limit tension of the tension spring 210; then the installation pipe body 241 is rotated to adjust the height of the spring telescopic rod 240, so that the distance between the upper end of the spring telescopic rod 240 and the outer convex ring 421 is less than the distance between the lower end of the vertical shaft 420 and the upper end of the second connecting piece 233b.

[0096] The first time, open the discharge motor 323, rotating brush 324 rotation so that the gasket 999 through the discharge hole dropped on the receiving groove. Lifting mechanism 430 drive vertical shaft 420 down, when the outer convex ring 421 away from the first inductor 500 inductive range, lifting mechanism 430 drive vertical shaft 420 up after the outer convex ring 421 into the first inductor 500 inductive range, trigger drive motor 350 on the feeding seat 340 gasket 999 delivery.

[0097] With the receiving groove of the feeding seat 340 gradually close to the countersunk section 252, the magnetic force of the magnet 231 on the gasket 999 gradually increases, when the vertical component of the magnetic force is greater than the weight of the gasket 999, the gasket 999 is attracted to the countersunk section 252 by the magnet 231, the receiving groove of the feeding seat 340 reaches the bottom of the countersunk section 252, and then moves reversely to the bottom of the discharge hole, receiving the next gasket 999 dropped through the discharge hole.

[0098] Then, the riveting action: the rivet is placed at the bottom of the vertical shaft 420, the rivet hole on the nameplate is sleeved on the rivet, the lifting mechanism 430 drives the vertical shaft 420 to move down, when the outer convex ring 421 contacts the upper end of the spring telescopic rod 240, the vertical shaft 420 and the sliding seat 230 move down synchronously, the tension spring 210 is gradually elongated. When the lower end of the connecting part 233 abuts on the nameplate, the sliding seat 230 no longer moves down, and the tension spring 210 no longer elongates, the vertical shaft 420 continues to move down, and the first spring 242 is gradually compressed; then the lower end of the vertical shaft 420 contacts the upper end of the rivet and presses down to anchor the rivet and the gasket together. Finally, the lifting mechanism 430 drives the vertical shaft 420 to move up, in the process of upward movement of the lifting mechanism 430, the first spring 242 gradually elongates, then the tension spring 210 gradually shortens and drives the sliding seat 230 to move up, then the outer convex ring 421 separates from the spring telescopic rod 240, finally, the outer convex ring 421 enters the inductive range of the first inductor 500 and triggers the drive motor 350 to deliver the next gasket 999 to the feeding seat 340.

[0099] When the next gasket 999 is attracted to the countersunk section 252 by the magnet 231, the riveting action can be performed.

[0100] According to the technical scheme, the adsorption group 200, the gasket feeding group 300 and the riveting device 400 are arranged on the workbench 100, in the process that the gasket feeding group 300 feeds the gasket 999 to the adsorption group 200, the magnetic attraction force of the magnet 231 to the gasket 999 gradually increases along with the gradually close of the receiving groove of the feeding seat 340 to the countersunk section 252, when the vertical component of the magnetic attraction force is greater than the gravity of the gasket 999, the gasket 999 is adsorbed to the countersunk section 252 by the magnet 231, the adsorption group 200 realizes the adsorption of the gasket 999 on the feeding path, and the gasket 999 does not need to be lifted and lowered with the whole disc body 321 and the gasket 999 in the disc body 321 for each feeding, time consumption is relatively less, and efficiency is relatively high.

[0101] It should be noted that the space adsorption refers to the adsorption by the magnetic attraction force without direct contact.

[0102] It should be noted that the space adsorption refers to the adsorption by the magnetic attraction force without direct contact.
