[0027] Among them, the limiting device includes a first cross bar 11 arranged at the top of the first column 3 and parallel to the long side of the transition frame 2, and a front bar 12 perpendicular to the first cross bar 11 and the first column 3, and also includes a second cross bar 13 arranged at the top of the second column 4 and in a straight line with the first cross bar 11. The outside of the first cross bar 11 and the second cross bar 13 are wrapped with a soft sheath.

[0028] In addition, in this embodiment, a position detection device 14 for detecting the door assembly 5 is provided on the platform 1, and a distance detection sensor 15 for detecting the position of the linear guide clamp 9 is provided on the transition frame 2.

[0029] like Figure 2As shown, the angle adjustment device 8 includes a placement cylinder 16 fixedly mounted on the transition frame 2 or the linear guide clamp 9, one end of the placement cylinder 16 faces outward, and a fixed turntable 17, an adjusting turntable 18, a spring 19 and a nut 20 are sequentially sleeved on the placement cylinder 16 from the inside to the outside, the fixed turntable 17 is fixedly sleeved on the placement cylinder 16, the adjusting turntable 18 is rotatably sleeved on the placement cylinder 16, the nut 20 is screwed on the end of the placement cylinder 16, one end of the spring 19 abuts against the nut 20, and the other end abuts against the adjusting turntable 18, the first slot 6 and the second slot 7 are both mounted on the adjusting turntable 18, and a plurality of corresponding protrusion structures are provided on the two opposite surfaces of the fixed turntable 17 and the adjusting turntable 18, and are interlocked with each other, and under the pressure of the spring 19, the two can still keep a fixed relative position under a certain torque, and if the upper limit value of the torque needs to be adjusted, the nut 20 can be rotated to further adjust the pressure of the spring 19.

[0030] In this embodiment, a gasket is provided between the nut 20 and the spring 19, a plurality of position identification bolts 22 are provided on the adjustment turntable 18, a plurality of position identification sensors 21 matching the position identification bolts 22 are provided on the fixed turntable 17, and an adjustment slot 24 for inserting an adjustment pin 23 of the carrying gripper is provided on the adjustment turntable 18.

[0031] When the universal cover transition platform of this embodiment is used, when a new vehicle model is introduced, one end of the door assembly 5 is placed on the first slot 6, and then the angle adjustment device 8 connected to the first slot 6 is adjusted to make the door assembly 5 lean against the limit device, the front end of the door assembly 5 leans against the front block rod 12, and the rear part leans against the first cross bar 11 and the second cross bar 13 respectively. Specifically, the adjustment of the first slot 6 is achieved by adjusting the adjustment dial 18. At this time, the second slot 7 generally does not contact the door assembly 5.

[0032] Then adjust the position of the linear guide clamp 9 so that the second slot 7 is directly below the door assembly 5, adjust the angle adjustment device 8 connected to the second slot 7 so that the second slot 7 is consistent with the bottom of the door assembly 5, which is also achieved by adjusting the adjustment dial 18 on the angle adjustment device 8, and then adjust the angle adjustment device 8 connected to the first slot 6 so that the door assembly 5 is placed on the second slot 7, and remember the angles of the two angle adjustment devices 8 at this time through the position recognition sensor 21, and remember the position of the linear guide clamp 9 at this time through the distance detection sensor 15, which is the control parameter of the door assembly 5 of this model.

[0033] When switching vehicle models during the production process, the angle of the angle adjustment device 8 and the position of the linear guide clamp 9 are adjusted to match the vehicle model, and the door assembly 5 of the vehicle model can be used. Specifically, the adjustment pin 23 of the handling gripper on the handling robot is inserted into the adjustment slot 24 of the angle adjustment mechanism 8, so that the adjustment turntable 18 rotates around the placement cylinder 16 to a certain specific angle. At this time, the position identification sensor 21 will identify the position of the position identification bolt 22, thereby confirming whether the first slot 6 and the second slot 7 on the adjustment turntable 18 are in the required state. After the adjustment of the two angle adjustment mechanisms 8 is completed, the adjustment pin 23 of the handling gripper on the handling robot is inserted into the second slot 7, and then the linear guide clamp 9 releases the guide rail 10. The adjustment pin 23 of the handling gripper pushes the linear guide clamp 9 and the angle adjustment mechanism 8 thereon until the distance detection sensor 15 detects that it has reached the specified distance, and then the linear guide clamp 9 is re-locked, and the vehicle model switch is completed.

[0034] During production: the handling robot carries the door assembly 5, and places the lower part into the first card slot 6 and the second card slot 7, leaning against the first cross bar 11 and the second cross bar 13, with the front part against the front bar 12. The overall position is kept unique based on gravity and the transition platform structure, and the subsequent robot grabs the door assembly 5 from the transition platform to perform the next sequence operation.
