[0041] The principle of this utility model is:

[0042] When the utility model is used, the workpiece 5 to be welded is clamped and fixed on the bracket 123 by the clamp 124. During the process, the parts of the workpiece 5 to be welded have not been welded together or are only spot-welded and need to be further fixed. After the parts of the workpiece 5 to be welded are clamped and relatively fixed by the clamp 124, the rotation displacement mechanism 11 is rotated 180° to rotate the clamped and fixed workpiece 5 to the bottom of the dust cover 31, so that the fixed workpiece 5 to be welded can be welded by the welding machine or the welding robot 25. In this process, it should be noted that in the actual workpiece 5, the welding process is carried out by the welding machine or the welding robot 25. In the industry, it is not convenient for the rotating position changing mechanism 11 to rotate continuously in one direction when cables and gas lines are involved. The rotating position changing mechanism 11 can be rotated 180° clockwise first, and one side is rotated to the bottom of the dust cover 31, while the other side can start to clamp and fix the workpiece 5 to be welded. After the welding on one side is completed, it is rotated counterclockwise to rotate the side after the finished workpiece 6 is detached from the welding, and the side that clamps the workpiece 5 to be welded is rotated to the bottom of the dust cover 31, and this is repeated to achieve an efficient and continuous welding process.

[0043] The above-mentioned welding process involves a welding machine, a welding wire barrel 23, a balancer 24, a welding robot 25 (such as FANUC robot M-10iD / 8L) and a gun cleaner 26 (such as KingCrafter, TBI300), etc. Since they are existing mature technologies and equipment, they are not difficult for technical personnel in this field to understand and will not be described in detail here; at the same time, the smoke generated during the welding process is collected into an industrial dust collector 33 (such as VJF-5.5) through a dust suction pipe 32. The industrial dust collector 33 is an existing equipment and will not be described in detail here.

[0044] After the welding of the workpiece 5 to be welded under the dust cover 31 is completed, the flip clamping mechanism 12 flips 180° (it should be noted that in actual production, depending on the different products, the flip clamping mechanism can also rotate a specified angle to complete the welding of the side or bottom surface). At this time, the transfer device 413 (which is a pneumatic cylinder, the principle is relatively simple and will not be repeated) rises to support the finished workpiece 6, and then the clamp 124 opens to lower the finished workpiece 6 to the first-level conveying mechanism 41 below. After the finished workpiece 6 is lowered, the flip clamping mechanism 12 flips 180° in the opposite direction and resets; the finished workpiece 6 located on the first-level conveying mechanism 41 is conveyed to the second-level conveying mechanism 42. At this time, the second active chain conveyor 421 stops conveying, and the second active chain conveyor 421 is lifted to the height of the third conveying mechanism by the lifting mechanism 422, and then the second active chain conveyor 421 starts conveying again, and the finished workpiece 6 is conveyed to the end of the workstation via the third conveying mechanism, and then it can be transferred and stored.

[0045] During the normal operation of the utility model, it is essential to involve the layout of lines and optical cables, and various sensors for motion control, such as making the rotating frame 113 rotate 180° clockwise and counterclockwise, such as the upside down flipping of the flipping clamping mechanism 12 and the detection of the finished workpiece 6 during the conveying process. Since it is an existing mature technology, it is not difficult for technical personnel in this field to understand and will not be elaborated.

[0046] At the same time, for the utility model, in the actual process of automated welding, omissions are inevitable, so a manual re-inspection stage is required. The finished workpiece 6 after welding is lifted by the second conveying mechanism, which is convenient for the inspection personnel to check for deficiencies and make up for the gaps, and convenient for re-welding, which is more convenient to use. At the same time, the straightening mechanism 432 straightens the deformation of the finished workpiece 6 produced during the processing. For example, the finished workpiece 6 sometimes bends due to thermal effects during the processing (the deformation is small). At this time, the positions of the two slides 4321 are freely adjusted, and the finished workpiece 6 is lifted and clamped by the straightener 4322 (which is a pneumatic cylinder, the principle is relatively simple and will not be repeated. The upper end of the straightener 4322 can only rise to the normal height of the finished workpiece 6), so that the finished workpiece 6 can be straightened to ensure the quality of the product.
