[0017] In order to make the patent purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0018] In order to illustrate the technical solutions of the present application, the following specific examples are used to illustrate the technical solutions of the present application.

[0019] In order to facilitate the description, only parts related to the embodiments of the present application are shown.

[0020] In combination with Figures 1-4As shown, the AGV trolley for wire harness tray transfer comprises an AGV trolley body 1, a liftable top tray 3 is arranged in the AGV trolley body 1, a circular opening 4 is arranged at the axial position of the top tray 3, a ring-shaped positioning seat 5 is arranged in the circular opening 4, a positioning rod 6 is arranged in the positioning seat 5, a locking assembly for fixing the positioning rod 6 is arranged on the positioning seat 5, a pair of sliding grooves 7 are arranged in the positioning seat 5, a clamping groove 8 is arranged at the bottom of the positioning rod 6, the locking assembly comprises a clamping block 9 arranged in the sliding groove 7, the front end of the clamping block 9 is clamped into the clamping groove 8, a pull rod 10 is arranged at the tail end of the clamping block 9, the pull rod 10 penetrates out of the positioning seat 5 and is provided with a pull ring 11, and an extrusion spring 12 is arranged on the pull rod 10 and located in the sliding groove 7.

[0021] In the processing of the wire harness tray, the AGV trolley is often used to transfer the wire harness tray from the previous station to the next station. The AGV trolley is provided with a top tray, and a positioning rod is arranged on the top tray. When the AGV trolley moves to the previous station, a mechanical hand clamps and transfers the wire harness tray to the AGV trolley, and in the transfer process, the circular opening penetrates through the positioning rod and the wire harness tray falls on the top tray. Then, after the AGV trolley moves to the next station, another mechanical hand takes down the wire harness tray, thereby completing the transfer of the wire harness tray.

[0022] Since the circular openings of different specifications of the winding trays are different in size, when different specifications of the winding trays need to be transferred, the matching positioning rods can be replaced to adapt to different specifications of the winding trays, so that the wire harness tray can be prevented from shaking in the transfer process. The lower ends of the positioning rods of all specifications are the same in diameter.

[0023] In the structure, when the different positioning rods need to be replaced, the worker can first pull the two pull rings, and the clamping block is separated from the clamping groove at the bottom of the positioning rod under the pulling of the pull rod. At this time, the positioning rod can be directly taken out. After the positioning rod is taken out, the worker releases the pull ring. Under the action of the extrusion spring, the clamping block is reset, and the front end of the clamping block is exposed from the sliding groove by a small distance. Then, the worker puts the to-be-replaced positioning rod into the positioning seat according to the requirements, and the locking assembly re-fixes and locks it.

[0024] In the structure, the front end of the clamping block 9 is formed with a forward and downward extrusion slope. When the to-be-replaced positioning rod is installed on the positioning seat, the bottom of the positioning rod is aligned with the positioning seat, and the positioning rod is directly inserted into the positioning seat. In this process, the bottom of the positioning rod first extrudes the clamping block to move backward and forms an avoidance until the positioning rod is completely inserted into the positioning seat.

[0025] When the clamping block moves backward, the extrusion spring is compressed. After the positioning rod is inserted into the positioning seat, the two clamping blocks are arranged opposite to the clamping groove, and the extrusion spring immediately restores the deformation and pushes the clamping block into the clamping groove. The two clamping blocks are used to lock and limit the positioning rod.

[0026] In addition, as Figure 2 , the top plate 3 is formed with a notch 14 corresponding to the pull ring 11. The notch has an avoiding effect. It can avoid the interference of the top plate during the pulling of the pull ring.

[0027] Further, as a preferred structure, as Figure 4 , the AGV trolley body 1 includes a bottom plate 1.1 and a trolley cover 1.2, the bottom plate 1.1 is provided with a pair of walking wheels 15 on the left and right sides, and a slide 16 is further provided between the same pair of walking wheels 15, the slide 16 is provided with a drive seat 17, one side of the drive seat 17 is rotatably provided with a drive wheel 18, and the other side is provided with a drive motor 19 for driving the drive wheel 18 to rotate, the drive seat 17 is provided with a guide rod 20, the guide rod 20 can pass through the top surface of the slide 16, and the guide rod 20 is provided with a buffer spring 21 inside the slide 16.

[0028] The bottom plate is not only provided with two pairs of walking wheels, but also provided with a pair of drive wheels. The drive wheels are driven to rotate by the drive motor, thereby driving the whole vehicle to walk. When the whole vehicle is in the process of transfer, if the drive wheels encounter uneven road conditions, the drive wheels may vibrate up and down in a small amplitude. In this process, the drive seat also vibrates up and down, and the buffer spring deforms slightly. Under the buffering of the buffer spring, the amplitude of the up and down shaking of the drive wheel is reduced, thereby improving the stability of the whole vehicle when walking.

[0029] In addition, as Figure 4 , each walking wheel is installed on the bottom plate through a buffer assembly. The buffer assembly includes a buffer seat 22, the buffer seat 22 penetrates downward into a four-pole short pole 30, the bottom of the short pole 30 is commonly provided with a base 31, the walking wheel 15 is installed on the base 31, the base 31 is provided with a buffer rod 23 upward, the buffer rod 23 penetrates out of the buffer seat 22 and is screwed with a fixing nut 24. The buffer rod is provided with a shock absorbing spring 25 inside the buffer seat.

[0030] When the whole vehicle is walking, if the walking wheel also passes through the uneven road, the walking wheel will also shake up and down. Similarly, the walking wheel drives the base to move up and down in a small amplitude, which can also reduce the amplitude of the up and down shaking of the walking wheel under the action of the shock absorbing spring, thereby further improving the stability of the whole vehicle when walking.

[0031] In this structure, the top surface of the trolley cover 1.2 is opened with a top opening 26, the bottom plate 1.1 is provided with two pairs of bearing seats 27 on the left and right sides, each bearing seat 27 penetrates a support rod 28, and the support rod 28 is commonly provided with the top plate, the bottom plate 1.1 is further provided with an electric push rod 29, and the drive shaft of the electric push rod 29 is connected with the top plate 2.

[0032] When the top disc needs to be raised and lowered, the electric push rod drives the vertical movement of the top disc. The top disc drives the vertical movement of the support rod in the bearing seat during vertical movement. When the four bearing seats jointly support the top disc, the top disc is located at the lowest position.

[0033] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
