[0067] The traditional AGV assembly process often has only one lifting device, which only drives the AGV trolley 8 to rise, and then the welded car body needs to be manually lifted and flipped by humans, which is time-consuming, labor-intensive and may also pose a safety hazard.

[0068] Combine the following Figures 1 to 7 , describing an embodiment of the present invention.

[0069] According to an embodiment of the present invention, on the one hand, an AGV auxiliary assembly flipping mechanism is provided, comprising: a base frame 1, a support structure 2, a rotating wheel 3 and a clamping flipping structure.

[0083] Adjust the distance between the fixed bracket assembly 201 and the floating bracket assembly 202: lift up the first pin 224 in the floating bracket assembly 202, loosen the guide rail clamp 223, push the entire floating bracket assembly 202 to move on the floating guide rail 6, and determine the pin hole into which the first pin 224 needs to be inserted according to the length of the AGV trolley 8 that needs to be flipped. After moving to the appropriate position, insert the first pin 224 into the pin hole and lock the guide rail clamp 223.

[0084] Adjust the distance between the two clamping plates 406: loosen the clamping plates 406 according to the width of the AGV trolley 8 to be flipped.

[0085] The fastener 7 on the second movable groove moves the locking rod 415 out of the safety socket of the safety plug plate 414, and the hand wheel 407 is rotated to drive the screw rod 402 to rotate. Under the guidance of the guide rod 403, the first movable rods 404 and the fixed blocks 413 on both sides are driven to approach or move away from each other at the same time, and the distance between the two clamping plates 406 is adjusted until it matches the width of the AGV trolley 8, and then the fastener 7 on the second movable groove is tightened into the second fixing hole to fix the fixed block 413 on the rotating wheel 3. The locking rod 415 is reinserted into the safety socket of the safety plug plate 414 to fix the distance between the two clamping plates 406.

[0086] Adjust the clamping plate 406: loosen the fastener 7 on the first movable groove, move the second movable rod 405 in the movable area until it moves to a suitable position, re-tighten the fastener 7 on the first movable groove into the first fixing hole, and determine the clamping position of the clamping plate 406.

[0087] Clamp the first positioning block 411 and the second positioning block 412 onto the AGV trolley 8: pull the pressure rod 418, and fix the second positioning block 412 with the quick clamp 417 so that the positioning groove on it faces downward and is clamped on the upper side of the AGV trolley 8. Loosen the fastener 7 on the guide groove. In the initial position, the second positioning block 412 is located at the farthest limit position away from the first positioning block 411. Rotate the adjustment screw 410 so that the adjustment mounting plate 409 and the second positioning block 412 are close to the first positioning block 411 along the guide groove until the positioning groove on the first positioning block 411 is clamped on the lower side of the AGV trolley 8. Tighten the fastener 7 on the guide groove to fix the adjustment mounting plate 409 and the second positioning block 412 for a second time.

[0088] Turn over the AGV trolley 8: Pull out the second latch 206 from the adjustment socket 301 of the rotating wheel 3, rotate the rotating wheel 3, and rotate it with the central axis of the rotating wheel 3 as the rotation center. When it rotates to a suitable angle, insert the second latch 206 into the corresponding adjustment socket 301 of the rotating wheel 3, so as to fix the rotation angle of the AGV trolley 8. Since the adjustment sockets 301 on the rotating wheel 3 are arranged in a circular array, the angle between any two adjacent adjustment sockets 301 is the same, and the staff can also control the rotation angle of the AGV according to the adjustment sockets 301 to improve work efficiency.

[0089] The AGV-assisted assembly flipping mechanism provided in the present invention is different from the traditional manual lifting and assisted flipping method. It uses a mechanical device to flip, which greatly improves labor efficiency, saves time and effort, and reduces the risk of collision caused by lifting. At the same time, this mechanism adopts a purely mechanical mechanism design, so it is safe and reliable, low cost, and easy to operate.

[0090] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
