[0029] The first clamping jaws 512 are connected with the first telescopic rod 513 for moving up and down, the first telescopic rod 513 is connected with the second telescopic rod 510 for moving left and right, and the distribution plate 515 is connected with a third telescopic rod 547 for moving left and right.

[0030] After the device is started, the joints 511 in the storage plate 581 are located at the initial position, the first telescopic rod 513 drives the first clamping jaws 512 to move downward to clamp the joints 511; after clamping, the first telescopic rod 513 drives the first clamping jaws 512 to move upward, and then the second telescopic rod 510 is extended to drive the second horizontal plate 514, the first telescopic rod 513 and the first clamping jaws 512 to move rightward along the first linear guide 516, until the first clamping jaws 512 move to the position directly above the distribution plate 515 (which is the leftmost position of the distribution plate 515); the first telescopic rod 513 drives the first clamping jaws 512 to move downward to place the joints 511 on the distribution plate 515; then the first telescopic rod 513 moves upward to reset, and the second telescopic rod 510 retracts to reset, preparing for the next clamping work. The distribution plate 515 loaded with the joints 511 moves rightward to the joint gluing station under the drive of the third telescopic rod 547, and at this position, the joints 511 in the distribution plate 515 are located directly below the second clamping jaws 519.

When the power device 508 is started, the third flat plate 550 and the components mounted thereon will move.

[0033] The second vertical plate 549 is arranged on the third flat plate 550, the fifth telescopic rod 548 is arranged on the side wall of the second vertical plate 549, one end of the fifth telescopic rod 548 is hinged with the rotary accessory 522, the other end of the rotary accessory 522 is connected with the blocking block 520, the blocking block 520 is located on one side of the second vertical plate 549, the rotary block 521 is arranged on the other side of the second vertical plate 549, and the rotary shaft of the rotary block 521 penetrates through the second vertical plate 549 and is connected with the blocking block 520. The fourth telescopic rod 524 is arranged on the rotary block 521, and the second clamping jaw 519 is arranged on the fourth telescopic rod 524. When the distribution plate 515 moves right to the joint gluing station under the driving of the third telescopic rod 547, the fourth telescopic rod 524 is elongated to drive the second clamping jaw 519 to move downward to clamp the joint 511 from the distribution plate 515, and then the second clamping jaw 519 moves upward to reset; the fifth telescopic rod 548 is elongated to drive the rotary accessory 522, the blocking block 520 and the rotary block 521 to rotate, the rotary block 521 drives the fourth telescopic rod 524 and the second clamping jaw 519 to rotate synchronously until 90°, so that the second clamping jaw 519 and the joint 511 clamped thereby are changed from the vertical state to the horizontal state, and are ready for gluing the joint 511.

[0034] The second clamping jaw 519 is connected with the fourth telescopic rod 524 for driving the second clamping jaw 519 to move upward and downward, and the fourth telescopic rod 524 is connected with the fifth telescopic rod 548 for driving the fourth telescopic rod 524 to rotate; The clamping and conveying device 560 further comprises the power device 508 for driving the fifth telescopic rod 548, the fourth telescopic rod 524 and the second clamping jaw 519 to move back and forth.

[0035] In the embodiment, the fourth telescopic rod 524 and the fifth telescopic rod 548 are both thin-wall air cylinders.

[0036] The clamping and conveying device 560 further comprises a buffer assembly for angle adjustment of the rotation of the fourth telescopic rod 524. The buffer assembly comprises a first buffer 518 mounted on the second vertical plate 549 and a second buffer 523 mounted on the second vertical plate 549. The fifth telescopic rod 548 is elongated to drive the rotation of the rotating accessory 522, the blocking block 520 and the rotating block 521 and the like. The elongation distance of the fifth telescopic rod 548 can be preset to ensure that the final rotation angle is 90°, facilitating subsequent glue coating and joint installation.

[0037] The first buffer 518 and the second buffer 523 are conventional hydraulic buffers, and the specific structure is not described in detail in the present embodiment. The rotation of the second clamping jaw 519 can be buffered by the cooperation of the first buffer 518, the second buffer 523 and the blocking block 520, so that the rotation is smooth, and the harsh friction and vibration sound when the rotation is in place is avoided. During the process of clamping the joint 511 and rotating the second clamping jaw 519 to horizontal, the first buffer 518 limits the limit position of the rotation thereof, ensures that it is rotated to horizontal, facilitates the glue coating of the joint 511 and the installation thereof on the conduit 533; after the joint 511 is installed on the conduit 533 by the second clamping jaw 519, during the process of downward rotation back to the original position, the second buffer 523 limits the limit position of the rotation thereof, ensures that it is rotated to vertical downward, and facilitates the next clamping.

The rack 534 is arranged on the third linear guide rail 536, the rotating shaft 532 is arranged on the third vertical plate 531, the gluing shaft 525 is installed on the rotating shaft 532, and the gear 535 meshing with the rack 534 is further arranged at the end of the rotating shaft 532. When the sixth telescopic rod 543 is elongated, the third linear guide rail 536 and the rack 534 are synchronously moved upward, the gear 535 drives the rotating shaft 532 and the gluing shaft 525 to rotate downward, and the gluing shaft 525 is immersed in the glue storage groove 544 to take glue; then the sixth telescopic rod 543 is retracted, the gluing shaft 525 rotates upward and returns to the horizontal state; then the seventh telescopic rod 546 is elongated upward, so that the first connecting plate 540, the second connecting plate 541 and the parts (especially the gluing shaft 525) installed thereon are integrally moved upward, so that the height of the gluing shaft 525 is consistent with the height of the second jaw 519.

[0042] After the second jaw 519 and the joint 511 clamped thereby are changed from the vertical state to the horizontal state in the foregoing clamping and conveying device 560, the power device 508 is started, the screw rod 505, the third flat plate 550 and the parts (especially the second jaw 519) installed on the third flat plate 550 are moved forward, the joint 511 cooperates with the gluing shaft 525, and the gluing action on the joint 511 is completed; then the power device 508 is started in the reverse direction again, the screw rod 505, the third flat plate 550 and the parts (especially the second jaw 519) installed on the third flat plate 550 are moved backward to return to the original position, the seventh telescopic rod 546 is retracted downward, integrally moving the first connecting plate 540, the second connecting plate 541 and the parts installed thereon downward to return to the original position, so that the height of the gluing shaft 525 is lower than the height of the second jaw 519, and does not affect the continuous forward movement of the second jaw 519 (cooperating with the guide pipe 533 to complete the joint installation).

[0043] In the embodiment, the sixth telescopic rod 543 is a thin-walled air cylinder, and the seventh telescopic rod 546 is a sliding table air cylinder.
