[0056] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0057] Example 1: Reference Figures 1 to 9 As shown, a threaded cap O-ring automatic assembly device comprises:

[0058] The material conversion device 1 includes a material turntable 11 and a motor for driving the material turntable 11 to rotate. The material conversion device 1 is used to adjust the position of the O-ring and the thread head. In this embodiment, four groups of thread sleeve placement groups are arranged in the circumferential direction on the material turntable 11, and each group of thread sleeve placement groups is provided with four thread sleeve placement heads 111.

[0059] The threaded sleeve feeding device 2 is used to transfer the threaded sleeve and place it on the material turntable 11; the threaded sleeve feeding device 2 is arranged in the circumferential direction of the material turntable 11;

[0060] An O-ring feeding device 3 is used to transfer and place the O-ring on the material turntable 11. The O-ring feeding device 3 is arranged in the circumferential direction of the material turntable 11;

[0061] The product unloading device 4 is used to remove the assembled O-ring and threaded sleeve from the material turntable 11; the product unloading device 4 is arranged in the circumferential direction of the material turntable.

[0062] Reference Figure 2 and Figure 3 As shown, the threaded sleeve feeding device 2 comprises:

[0063] The threaded sleeve vibration feeding device 21 comprises a threaded sleeve vibration feeding plate 211, a threaded sleeve vibration transmission plate 212 connected to the threaded sleeve vibration feeding plate 211, and a threaded sleeve transmission groove 213 arranged on the threaded sleeve vibration transmission plate 212; in this embodiment, four threaded sleeve transmission grooves 213 are arranged, so that four threaded sleeves can be fed at the same time;

[0064] The threaded sleeve pneumatic clamp 22 (belonging to the prior art) is used to clamp the threaded sleeve. In this embodiment, there are four threaded sleeve pneumatic clamps, all of which are fixedly arranged on the threaded sleeve pneumatic clamp mounting plate 26;

[0065] The mobile device 5 and the threaded sleeve pneumatic clamp mounting plate 26 are arranged on the mobile device 5; the mobile device 5 can drive the threaded sleeve pneumatic clamp 22 to remove the threaded sleeve from the threaded sleeve transfer groove 213, and then place the threaded sleeve on the threaded sleeve placing head 111 of the material turntable 11.

[0066] A socket plate 23 is provided at the output end of the threaded sleeve transfer groove 213, and a socket groove 231 cooperating with the threaded sleeve is provided on the socket plate 23; a dislocation slider 24 is fixedly connected to the bottom of the socket plate 23; a rotating screw rod 25 is provided below the socket plate 23, and the rotating screw rod 25 is driven to rotate by a motor, and the rotating screw rod 25 is vertically arranged to the threaded sleeve transfer groove 213, and the dislocation slider 24 cooperates with the rotating screw rod 25.

[0067] The specific working principle of the threaded sleeve feeding device 2 is as follows: the threaded sleeve moves along the threaded sleeve transfer groove 213 through the vibration of the threaded sleeve vibrating feeding plate 211. When the threaded sleeve vibrates to the output end of the threaded sleeve transfer groove 213, it falls into the sleeve connection groove 231 on the sleeve plate 23. At this time, the threaded sleeve sensor arranged on the sleeve connection groove 231 detects the existence of the threaded sleeve (belonging to the prior art), and the motor drives the rotation of the rotating screw 25, so that the dislocation slider 24 moves along the rotating screw 25, so that the sleeve connection groove 231 and the threaded sleeve sensor above it are offset, and then the moving device 5 controls the threaded sleeve pneumatic clamp 22 to take the threaded sleeve out of the sleeve connection groove 231, and then the moving device 5 places the threaded sleeve on the threaded sleeve placement head 111. Thereafter, the dislocation slider 24 is reset to wait for the threaded sleeve to be transferred next time. The sliding of the dislocation slider 24 can facilitate the pneumatic clamp 22 to clamp the threaded sleeve.

[0068] Reference Figures 4 to 6 As shown, the O-ring feeding device 3 comprises:

[0069] An O-ring vibration feeding device 31 includes an O-ring vibration feeding tray 311, an O-ring vibration transfer plate 312 connected to the O-ring vibration feeding tray 311, an O-ring transfer groove 313 arranged on the O-ring vibration transfer plate 312, and an O-ring placement table 314 arranged at the output end of the O-ring transfer groove 313, and an O-ring placement groove 315 matched with the O-ring is arranged on the O-ring placement table 314;

[0070] The automatic ring device 32 is used to take the O-ring out of the O-ring placement groove 315 and put the O-ring on the threaded sleeve;

[0071] The mobile device 5 , on which the automatic ferrule device 32 is arranged.

[0072] like Figure 6 As shown, the O-ring placement platform 314 is provided with a first sliding hole 316 in the vertical direction, and a first slider 317 and a first spring 318 are provided in the first sliding hole 316. The first spring 318 abuts between the bottom of the first sliding hole 316 and the first slider 317. A placement protrusion 319 protruding inwardly in the radial direction is provided in the circumferential direction near the upper end of the first sliding hole 316, and a placement sliding groove matching the placement protrusion 319 is provided in the circumferential direction of the first slider 317; the O-ring placement groove 315 is provided at the upper end of the first slider 317, and a placement platform transfer groove 3141 connecting the O-ring placement groove 315 and the O-ring transfer groove 313 is provided on the O-ring placement platform 314.

[0073] Refer to Figure 5 As shown, the automatic ferrule device 32 includes:

[0074] The air gripper mounting plate 321 is connected to the moving device 5;

[0075] A four-claw cylinder 322 is provided on the lower end surface of the claw mounting plate 321, and a pneumatic gripper 323 for opening the O-ring is provided at the end of the four-claw cylinder 322;

[0076] The ring slide bar 324 is passed through the air claw mounting plate 321, and the ring mounting plate 325 is arranged on the upper end of the ring slide bar 324;

[0077] The ring cylinder 326 is fixedly arranged on the ring mounting plate 325, and the movable end of the ring cylinder 326 is connected to the claw mounting plate 321;

[0078] The ring plate 327 is arranged at the lower end of the ring slide rod 324 , and a ring gripper 328 is arranged on the ring plate 327 . There is a gap between adjacent pneumatic grippers 323 , and the ring gripper 328 is matched with the gap between adjacent pneumatic grippers 323 .

[0079] The working principle of O-ring feeding device 3 is as follows: Figures 4 to 6As shown, the O-ring is moved along the O-ring transfer groove 313 of the O-ring vibration transfer plate 312 by the vibration of the O-ring vibration loading tray 311, and then the O-ring is transferred to the O-ring placement groove 315 on the O-ring placement table 314; then the moving device 5 drives the automatic ring device 32 to move above the O-ring placement groove 315, and then the moving device 5 drives the pneumatic gripper 323 in the contracted state to move downward, so that the pneumatic gripper 323 presses down the first slider 317, and at this time, since the O-ring is placed on the placement protrusion 319, the pneumatic gripper 323 passes through the O-ring, and then the four-claw cylinder 322 controls the pneumatic gripper 323 to open, and the pneumatic gripper 323 opens to make the O-ring be stretched, and then the moving device 5 drives the stretched O-ring to move to the top of the material turntable 11. At this time, a threaded sleeve has been placed on the threaded sleeve placing head 111 on the material turntable 11. The moving device 5 drives the stretched O-ring to move to the periphery of the threaded sleeve. Then the movable end of the ring cylinder 326 contracts, so that the distance between the ring mounting plate 325 and the air claw mounting plate 321 is reduced, so that the ring slide bar 324 slides, so that the ring plate 327 moves downward, and the ring plate 327 moves downward so that the ring gripper 328 moves downward to push the O-ring from the pneumatic gripper 323 to the threaded sleeve, completing the O-ring sleeve being set on the threaded sleeve. Then the moving device 5 and the automatic ring device 32 are reset to prepare for the next O-ring sleeve. The O-ring feeding devices 3 in this embodiment are provided with two groups, which are arranged along the circumferential direction of the material turntable 11. The O-ring transfer grooves 313 in each group of O-ring feeding devices 3 include a first transfer groove 3131 and a second transfer groove 3132. The first transfer groove 3131 is connected to the second transfer groove 3132. There are two second transfer grooves 3132, so that each group of O-ring feeding devices 3 can feed two O-rings at the same time. The two groups of O-ring feeding devices 3 just correspond to feeding four O-rings, which just cooperates with the threaded sleeve feeding device 2 to feed four threaded sleeves at one time.

[0080] like Figure 7 As shown, the product unloading device 4 includes an unloading mounting plate 43, unloading clamping claws 41 (belonging to the prior art) and an unloading disc 42, and the unloading mounting plate 43 is connected to the moving device 5. Four unloading clamping claws 41 are arranged on the unloading mounting plate 43, so that the threaded sleeve with the O-ring installed can be taken out from the material turntable 11 through the cooperation of the moving device 5 and the unloading clamping claws 41.

[0081] The specific working principle of the product unloading device 4 is as follows: the threaded sleeve with the O-ring installed is rotated to the corresponding position of the product unloading device 4 through the material turntable 11, and the moving device 5 controls the unloading clamp 41 to remove the threaded sleeve from the material turntable 11, and then places it on the unloading tray 42, so that the threaded sleeve moves along the unloading tray 42 and is collected.

[0082] The working principle of this embodiment is as follows: Figures 1 to 8 As shown, the threaded sleeve moves along the threaded sleeve transfer groove 213 through the vibration of the threaded sleeve vibration loading plate 211, and when the threaded sleeve vibrates to the output end of the threaded sleeve transfer groove 213, it falls into the socket groove 231 on the socket plate 23. At this time, the threaded sleeve sensor arranged above the socket groove 231 detects the existence of the threaded sleeve, and the motor drives the rotating screw 25 to rotate, so that the offset slider 24 moves along the rotating screw 25, so that the socket groove 231 and the threaded sleeve sensor above it are offset, and then the moving device 5 controls the threaded sleeve pneumatic clamp 22 to take the threaded sleeve out of the socket groove 231, and then the moving device 5 places the threaded sleeve on the threaded sleeve placing head 111.

[0083] The material turntable 11 drives the threaded sleeve to rotate, so that the threaded sleeve is transmitted to the position corresponding to the O-ring feeding device 3, and the O-ring moves along the O-ring transfer groove 313 of the O-ring vibration transfer plate 312 through the vibration of the O-ring vibration feeding disc 311, and then the O-ring is transferred to the O-ring placement groove 315 on the O-ring placement table 314; then the moving device 5 drives the automatic ring device 32 to move above the O-ring placement groove 315, and then the moving device 5 drives the pneumatic gripper 323 in the retracted state to move downward, so that the pneumatic gripper 323 presses down the first slider 317. At this time, since the O-ring is placed on the placement bump 319, the pneumatic gripper 323 passes through the O-ring, and then the four-claw cylinder 322 controls the pneumatic gripper 323 to open, and the pneumatic gripper 323 opens so that the O-ring is stretched, and then the moving device 5 drives the stretched O-ring to move to the top of the material turntable 11. At this time, a threaded sleeve has been placed on the threaded sleeve placing head 111 on the material turntable 11. The moving device 5 drives the stretched O-ring to move to the periphery of the threaded sleeve, and then the movable end of the ring cylinder 326 contracts, so that the distance between the ring mounting plate 325 and the air claw mounting plate 321 is reduced, so that the ring slide bar 324 slides downward, and the ring plate 327 moves downward. The downward movement of the ring plate 327 causes the ring gripper 328 to move downward to push the O-ring from the pneumatic gripper 323 to the threaded sleeve, completing the O-ring being set on the threaded sleeve, and then the moving device 5 and the automatic ring device 32 are reset to prepare for the next O-ring ring.

[0084] The material turntable 11 drives the threaded sleeve with the O-ring to rotate, so that the threaded sleeve rotates to a position corresponding to the product unloading device 4. The moving device 5 controls the unloading clamp 41 to remove the threaded sleeve from the material turntable 11, and then places it on the unloading tray 42, so that the threaded sleeve moves along the unloading tray 42 and is collected.

[0085] It should be noted that the mobile device 5 in this embodiment can use a four-axis robot to complete the relevant operations, and the relevant control technology involved in this embodiment belongs to the existing technology and will not be described in detail here.

The horizontal moving slide 512 is provided with a vertically arranged second slide rail 523, and the vertical moving slide 522 is provided with a second slide groove 524 that matches the second slide rail 523. The movable end of the vertical moving cylinder 521 is connected to the vertical moving slide 522.

[0090] The working principle of this embodiment is as follows: the vertical moving slide 522 is driven to move by the vertical moving cylinder 521, so that the vertical moving slide 522 can realize vertical movement, and the horizontal moving slide 512 is driven to move by the horizontal moving cylinder 511, so that the horizontal moving slide 512 can realize horizontal movement. Therefore, through the cooperation of the horizontal moving device 51 and the vertical moving device 52, the vertical moving slide 522 can be moved to various positions within a certain range of space.

A pin hole 69 is arranged on the side wall of the first sliding hole 316. A first magnet (not shown in the figure) is arranged at the end of the locking pin 67 close to the second sliding hole 611. A second magnet 332 corresponding to the position of the magnet is arranged on the side wall of the connecting column 33. The first magnet and the second magnet 332 have opposite magnetic poles.

[0099] In actual production, due to the small size and light weight of the O-ring, when the O-ring passes through the placement table transfer groove 3141, the O-ring placement table 314 is stationary, so that when the O-ring in the O-ring placement groove 315 is assembled on the threaded sleeve, the O-ring in the placement table transfer groove 3141 cannot be pushed into the O-ring placement groove 315 by the O-ring from the O-ring transfer groove 313. This causes a lack of O-rings in the O-ring placement groove 315 and an operating error when the O-ring is installed next time. In order to avoid the above situation, a transfer device is provided.

[0100] The specific working principle of this embodiment is as follows: Fig.10 As shown in the figure, it is the initial state of the transmission device. Then, the pneumatic gripper 323 moves downward to press the first slider 317 downward, so that the first slider 317 slides along the first sliding hole 316. When the first slider 317 slides, it pushes the second slider 61 to move downward. At this time, the transmission rack 63 moves downward with the second slider 61. Since the power gear 653 is a one-way transmission ratchet, although the transmission rack 63 transmits power to the power gear 653 through the power transmission device 66, the power gear 653 does not transmit power to the transmission rod 651; when the pneumatic gripper 323 is pressed down to the lowest end, when the second slider 61 slides to the position corresponding to the pin hole 69, the third spring 68 pushes the lock pin 67, so that the lock pin 67 cooperates with the pin hole 69, so that the second slider 61 is fixed. For specific states, refer to FIG. Fig.11 As shown; then the pneumatic gripper 323 rises, and since the second slider 61 is locked, only the first slider 317 moves upward under the action of the first spring 318. When the first slider 317 moves to the top, the second magnet 332 on the side wall of the connecting column 33 corresponds to the position of the through hole 612 as shown in FIG. Fig.12 As shown, the second magnet 332 generates an attractive force on the first magnet on the lock pin 67, so that the lock pin 67 disengages from the pin hole 69, thereby releasing the lock of the second slider 61, and the second slider 61 moves upward under the force of the second spring 62. At this time, the transmission rack 63 on the second slider 61 drives the first transmission gear 661 to rotate, so that the first transmission gear 661 drives the second transmission gear 662 to rotate, the second transmission gear 662 drives the third transmission gear 663 to rotate, the third transmission gear 663 drives the power gear 653 to rotate, the power gear 653 drives the transmission rod 651 to rotate, the transmission rod 651 drives the rolling wheel 652 to rotate, the rolling wheel 652 drives the transmission belt 64 to rotate, and then the O-ring in the transfer groove 3141 of the placement table is transferred to the O-ring placement groove 315 through the transfer belt 64 to ensure that the O-ring is placed in the O-ring placement groove 315; then the transmission device returns to the position shown in FIG. Fig.10 The initial state in , waiting for the next movement.

[0101] By providing the transfer device, it can be ensured that each time the pneumatic gripper 323 takes away the O-ring in the O-ring placement groove 315, the transfer device can ensure that there is an O-ring in the O-ring placement groove 315 the next time, which effectively prevents the operation error caused by the lack of O-ring in the O-ring placement groove 315. The transfer device pushes the O-ring forward only after the pneumatic gripper 323 is out of contact with the first slider 317.
