Through the cooperation of the first positioning assembly and the second positioning assembly, the rectangular frame is completely positioned and fixed on the welding seat. When the rectangular frame needs to be flipped, first, the first positioning assembly and the second positioning assembly release the positioning restriction on the rectangular frame. Then, the lead screw slide drives the rotary clamping assembly to move towards the rectangular frame, and the synchronous clamping cylinder drives the clamping block to clamp the middle position of the long side or short side of the fixed rectangular frame. Subsequently, the lifting assembly drives the lifting frame and the rectangular frame to rise, the rotary motor drives the rectangular frame to rotate 180°, then the lifting assembly drives the rectangular frame to descend and place it on the welding seat and reposition it.

A through hole 31 for the lifting frame 7 and the rotary clamping assembly 9 to pass through is provided on the welding seat 3. In this embodiment, the lifting assembly 6 uses an upgraded cylinder, and the lifting stroke of the lifting assembly 6 is not less than half of the length of the long side of the rectangular frame 10, so as to avoid collision with the welding seat 3 during the process of the rotary clamping assembly 9 driving the rectangular frame 10 to flip.

[0021] Referring to Figures 2 to 3, specifically, the first positioning component 4 includes a first positioning cylinder 41 fixedly connected to the welding seat 3 and a first L-shaped positioning block 42 fixedly connected to the telescopic end of the first positioning cylinder 41.

The second positioning component 5 includes a second positioning cylinder 51 fixedly connected to the welding seat 3 and a second L-shaped positioning block 52 fixedly connected to the telescopic end of the second positioning cylinder 51. The outer walls of the second L-shaped positioning block 52 are respectively abutted and fitted against two adjacent right-angle sides of the inner wall of the rectangular frame 10. The first positioning component 4 drives the inner walls of the first L-shaped positioning block 42 to be respectively abutted and fitted against two adjacent right-angle sides of the outer wall of the rectangular frame 10 through the first positioning cylinder 41, so as to realize the positioning of the right-angle part outside the rectangular frame 10. Similarly, the second positioning component 5 drives the outer walls of the second L-shaped positioning block 52 to be respectively abutted and fitted against two adjacent right-angle sides of the inner wall of the rectangular frame 10 through the second positioning cylinder 51, so as to realize the positioning of the right-angle part inside the rectangular frame 10. The rectangular frame 10 is completely positioned and fixed on the welding seat 3 through the cooperation of the first positioning component 4 and the second positioning component 5. In this embodiment, two sets of the first positioning component 4 and the second positioning component 5 are provided, which are respectively arranged at both ends of the diagonal of the rectangular frame 10 in a cross manner, so as to ensure the positioning accuracy of the rectangular frame 10 and reduce the use cost at the same time.

A clamping block 93 is fixedly connected to the clamping end of the synchronous clamping cylinder 92. The synchronous clamping cylinder 92 drives the clamping block 93 to clamp the middle position of the long side or the short side of the fixed rectangular frame 10. Then, the lifting component 6 drives the lifting frame 7 and the rectangular frame 10 to rise. After the rotary motor 91 drives the rectangular frame 10 to rotate 180°, the lifting component 6 drives the rectangular frame 10 to descend and place it on the welding seat 3 and reposition it. Since the middle position of the rectangular frame 10 is clamped, the position of the rectangular frame 10 relative to the first positioning component 4 and the second positioning component 5 does not change during the flipping process, which is convenient for repositioning. In this embodiment, the rotary motor 91 uses a stepping motor.
