[0050] Working principle of the utility model:

[0051] In the embodiment, the first direction is horizontal and perpendicular to the Y-axis direction, that is, the turning end of the first turning driving member 5 is the first direction, and the first turning frame 6 turns around the turning end of the first turning driving member 5. Since the turning mounting frame 8 is arranged on the first turning frame 6, the first turning frame 6 drives the turning mounting frame 8 to turn in the process of turning. On this basis, the turning mounting frame 8 is movably arranged on the first turning frame 6 and is turned by the second turning driving member 7. The turning end (i.e., the power output end) of the second turning driving member 7 is parallel to the Y-axis direction, that is, the turning mounting frame 8 turns around the turning end of the second turning driving member 7, so that the turning mounting frame 8 and the product to be machined clamped on the clamp are turned at multiple angles, and the laser welding mechanism 19 is used to realize 3D mirror welding. Specifically, the turning positioning member 11 arranged on the turning mounting frame 8 is used to position the product to be machined, i.e., the product to be welded. The turning detection member 13 can detect whether the product to be machined is powered off. Similarly, the clamping positioning member 14 of the clamping platform 1 is used to position the product to be machined. The clamping platform 1 is used to manually clamp the product to be machined and the product to be machined after welding. The Y-axis moving assembly 9 can drive the displacement mechanism to move to the front of the laser welding mechanism 19, so that the laser welding structure can weld the turned product to be machined, and the product to be machined after welding can be conveyed to the left end or the right end of the Y-axis moving assembly 9. Figure 1As shown, the leftmost end of the Y-axis moving assembly 9 is the leftmost end in the Y-axis direction, i.e., the second direction, and the leftmost end of the Y-axis moving assembly 9 is correspondingly provided with one multi-axis manipulator assembly, and the rightmost end of the Y-axis moving assembly 9 is correspondingly provided with another multi-axis manipulator assembly.

[0052] In use, the welded products need to be moved to the clamping platform 1 for further processing by the multi-axis manipulator assembly, and the adjacent another clamping platform 1 needs to be clamped with the products to be processed and then moved to the position changing mechanism by the multi-axis manipulator assembly to be sent to the lower side of the laser welding mechanism 19 for laser welding processing. That is, the products A on the first clamping platform 1 need to be transferred to the second clamping platform 1 for further processing after being welded by the laser welding mechanism 19 to form products B. Similarly, the second clamping platform 1 can place the products A after being welded by the laser welding mechanism 19 to form products B and then transfer them to the first clamping platform 1 for further processing. Further, the multi-axis manipulator 2 can drive the clamping mechanism to the adjacent Y-axis moving assembly 9 or clamping platform 1. Since the clamping base plate 10 is provided with clamping units 3 at both ends, each end of the clamping base plate 10 is provided with two clamping units 3 in this embodiment, and the two clamping units 3 are distributed on the upper and lower sides of the clamping base plate 10. Therefore, one end of the clamping base plate 10 can clamp two products to be processed at the same time, i.e., both ends of the clamping base plate 10 can clamp four products to be processed at the same time. One end of the clamping base plate can clamp two products A at the same time, and the other end of the clamping base plate can clamp two products B at the same time. The clamping mechanism moves from the Y-axis moving assembly 9 to the clamping platform 1, which drives two products A and two products B to move, or drives four products A or four products B to move, etc.

[0053] In this embodiment, Figure 3 As shown, the clamping unit 3 is in a clamped state, and one end of the two clamping arms 31 is close to each other to form a locked state. The outer end of the two clamping arms 31 is provided with a locking position 311. In this embodiment, a hole structure is selected, and the outer end of the two clamping arms 31 is provided with a hole structure coaxially arranged. The telescopic member is a telescopic cylinder. When the two clamping arms 31 are close to each other and fit together, the telescopic end of the telescopic cylinder passes through the hole structure of the two clamping arms 31 to lock the two clamping arms 31 to avoid separation, thereby avoiding the clamped products from falling off. Figure 3 The clamping unit 3 above the clamping base plate 10 is in a locked state, and the two clamping arms 31 are completely close to form a closed locking ring, as shown in Figure 3The telescopic member shown is located above the clamping substrate 10 and is disposed on the top of the clamping unit 3. The telescopic end of the telescopic member extends outward. The outer ends of the two clamping arms 31 located on the upper side of the clamping substrate 10 and the opening formed by the two clamping arms 31 are consistent with the telescopic direction of the telescopic member, that is, perpendicular to the direction of the clamping substrate 10. Figure 3 (The center is facing the lower right). Figure 5 The dashed line in the middle represents the path of the detection ray, etc. Figure 7 The middle part of the inspection line is a solid line. In addition, various detection elements can be set on the clamping platform 1 to detect whether the fixture and the product A or product B to be processed are in place.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
