[0050] Working principle of the present invention:

[0051] In this embodiment, there is no need to move the 3D galvanometer, so as to ensure the safety and stability of the 3D galvanometer. In this embodiment, the first direction is perpendicular to the Y-axis direction, that is, the flip end of the first flip driving member 5 is the first direction, and the first flip frame 6 flips with the flip end of the first flip driving member 5 as the rotation center. Since the flip mounting frame 8 is arranged on the first flip frame 6, the flip mounting frame 8 is driven to flip during the flipping process of the first flip frame 6. On this basis, the flip mounting frame 8 is movably arranged on the first flip frame 6 and flipped by the second flip driving member 7. The flip end (i.e., the power output end) of the second flip driving member 7 is parallel to the Y-axis direction, which can drive the flip mounting frame 8 to flip with the flip end of the second flip driving member 7 as the rotation center, so as to realize multi-angle flipping of the products to be processed installed on the fixture, and cooperate with the laser welding mechanism 19 to realize 3D galvanometer welding. Specifically, a flip positioning member 11 is arranged on the flip mounting frame 8 to position the products to be processed, i.e., the products to be welded. The flip detection member 13 can detect whether the products to be processed are powered off. Similarly, the clamping positioning member 14 of the clamping platform 1 is used to position the product to be processed. The clamping platform 1 is used to manually clamp the product to be processed and clamp the product to be processed after welding. The Y-axis moving component 9 can drive the displacement mechanism to move to the bottom of the laser welding mechanism 19, so that the laser welding structure can laser weld the flipped product to be processed. The welded product to be processed can be transported by the Y-axis moving component 9 to the leftmost or rightmost end of the Y-axis moving component 9. Figure 1As shown, the leftmost end of the Y-axis moving component 9 is in the Y-axis direction, that is, the leftmost side of the second direction. The leftmost end of the Y-axis moving component 9 corresponds to a multi-axis manipulator component, and the rightmost end of the Y-axis moving component 9 corresponds to another multi-axis manipulator component.

[0052] During use of this embodiment, the product to be processed after welding needs to be transferred to the clamping platform 1 through the multi-axis robot assembly for further processing, and the product to be processed on the other adjacent clamping platform 1 needs to be clamped and transferred to the displacement mechanism through the multi-axis robot assembly and sent to the bottom of the laser welding mechanism 19 for laser welding processing. That is, the product to be processed A located on the first clamping platform 1 is welded by the laser welding mechanism 19 to form the product to be processed B, which needs to be transferred to the second clamping platform 1 for further processing. Similarly, the second clamping platform 1 can place the product to be processed A, which is welded by the laser welding mechanism 19 to form the product to be processed B, which needs to be transferred to the first clamping platform 1 for further processing. Furthermore, the multi-axis robot 2 can drive the clamping mechanism to a nearby Y-axis moving component 9 or a clamping platform 1. Since the clamping units 3 are provided at both ends of the clamping substrate 10 of the clamping mechanism, in this embodiment, each end of the clamping substrate 10 is provided with two clamping units 3, and the two clamping units 3 are respectively distributed on the upper and lower sides of the clamping substrate 10. Therefore, one end of the clamping substrate 10 can clamp two products to be processed at the same time, that is, both ends of the clamping substrate 10 can clamp four products to be processed at the same time, one end of the holding substrate can clamp two products A to be processed at the same time, and the other end of the holding substrate can clamp two products B to be processed at the same time. The process of the clamping mechanism moving from the Y-axis moving component 9 to the clamping platform 1 drives the two products A to be processed and the two products B to be processed to move, or drives a combination of four products A to be processed or four products B to be processed to be transferred and placed for continuous processing.

[0053] In this embodiment, Figure 3 As shown, the clamping unit 3 is in a clamping state, and one end of the two clamping arms 31 is close to each other in a locked state, wherein the outer ends of the two clamping arms 31 are provided with locking positions 311. In this embodiment, a hole-like structure is selected, and the outer ends of the two clamping arms 31 are provided with hole-like structures and are coaxially arranged. The telescopic part 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-like structures of the two clamping arms 31 to lock the two clamping arms 31 to avoid separation from each other, thereby preventing the clamped product to be processed from falling off. Figure 3 In the figure, the clamping unit 3 located above the clamping substrate 10 is in a locked state, and the two clamping arms 31 are completely close to form a closed locking ring. Figure 3The telescopic member located above the clamping substrate 10 is arranged on the top of the clamping unit 3, and 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 horizontal direction of the clamping substrate 10 ( Figure 3 towards the lower right). Figure 5 The dotted line in the middle is the path of the detection ray. Figure 7 The middle part of the detection ray is a solid line. In addition, a variety of detection elements can be set on the clamping platform 1 to detect whether the clamp and the product A to be processed or the product B to be processed are in place.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also regarded as the protection scope of the present invention.
