Abstract
Description
Technical Field
[0001] This utility model relates to the field of welding machines, and in particular to a laser flat welding machine with positioning function. Background Technology
[0002] AI processors employ dedicated architectures such as Tensor Processing Units (TPUs) or Neural Processing Units (NPUs), optimized for parallel computing and matrix operations. This reduces data transfer latency and improves energy efficiency. In deep learning tasks (such as image recognition), AI processors offer faster floating-point operations and lower latency. However, AI processors consume more power than ordinary processors. For heat dissipation, AI processors typically use water cooling. They are equipped with a dedicated heatsink that continuously supplies coolant. This heatsink is made up of two parts welded together. The sealing of the heatsink welds plays a crucial role in the quality of the product. Traditionally, water-cooled heatsinks are manually welded, resulting in uneven welds, leaks, and coolant leakage. Furthermore, manual welding is inefficient, produces poor weld quality, and is costly. Currently, some automated welding equipment has appeared on the market. Some welding equipment uses a center clamping method to clamp the upper and lower parts of the radiator. This center clamping method is prone to causing misalignment between the upper and lower parts of the radiator, resulting in defective radiators. Other welding equipment uses an edge clamping method to clamp the upper and lower parts of the radiator. Because its clamping mechanism blocks the welding torch from welding the corresponding edge parts, after the welding torch has finished welding the edge parts that can be welded, the radiator needs to be repositioned to expose the unwelded parts before subsequent welding can be carried out. That is, the welding torch needs to be repositioned during the two welding processes. The repositioning of the welding torch is prone to missed welding or repeated welding, resulting in uneven weld points and incomplete welding seals, which reduces the yield of radiators.

The drawings illustrate preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.
[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0023] Reference Figure 1 As shown, this utility model discloses a laser flat welding machine with positioning function, including a machine base 1, a workpiece positioning mechanism 2, a welding torch positioning mechanism 3, a welding torch 4, a display bracket 5, and a display screen 6.

The display bracket 5 is mounted on the machine base 1, and the display screen 6 is mounted on the display bracket 5.
[0024] Reference Figure 2 and Figure 3 As shown, the workpiece positioning mechanism 2 includes a positioning table 7, a positioning component 8, a first spinning component 9, a second spinning component 10, a third spinning component 11, a fourth spinning component 12, a first side-pushing component 13, and a second side-pushing component 14. The positioning table 7 is mounted on the machine base 1, and the positioning component 8 is mounted on the positioning table 7 and is used to support the workpiece 15. The first spinning component 9, the second spinning component 10, the third spinning component 11, and the fourth spinning component 12 are mounted around the positioning component 8 on the positioning table 7. The three-spinning assembly 11 and the fourth-spinning assembly 12 respectively press the edge portion of the workpiece 15 to fix the workpiece 15 on the positioning assembly 8. The first side-pushing assembly 13 and the second side-pushing assembly 14 are respectively mounted on the positioning table 7, and the first side-pushing assembly 13 is located on one side of the positioning assembly 8. The first side-pushing assembly 13 and the second side-pushing assembly 14 respectively push the workpiece 15 on the positioning assembly 8 in the horizontal direction to perform lateral limiting and fixing of the workpiece 15. The direction in which the first side-pushing assembly 13 pushes the workpiece 15 is perpendicular to the direction in which the second side-pushing assembly 14 pushes the workpiece 15.
[0025] Reference Figure 3As shown, the positioning assembly 8 includes a first base 81, a second base 82, a first reference base 83, and a second reference base 84. The first base 81 and the second base 82 are respectively mounted on the positioning table 7 and are used to support the workpiece 15. The first reference base 83 and the second reference base 84 are respectively mounted on the positioning table 7. The first side push assembly 13 and the second side push assembly 14 push the workpiece 15 to the sides of the first reference base 83 and the second reference base 84 in mutually perpendicular directions.

[0026] By adopting the above technical solution, the first reference base 83, the second reference base 84, the first side push assembly 13 and the second side push assembly 14 work together to limit and fix the workpiece 15 in the horizontal direction, so as to ensure that the workpiece 15 is accurately and efficiently positioned before welding, thereby ensuring that the subsequent welding torch 4 welds the workpiece 15 with high precision, high efficiency and good welding effect.
[0027] Reference Figure 4 As shown, the first side-push assembly 13 includes a side-push drive device 131, a buffer pad 132, and a mounting bracket 133. The mounting bracket 133 is mounted on the positioning platform 7, the side-push drive device 131 is mounted on the mounting bracket 133 and the output end of the side-push drive device 131 faces the positioning assembly 8, and the buffer pad 132 is mounted on the output end of the side-push drive device 131. The first side-push assembly 13 is provided with at least one of these components. The structure of the second side-push assembly 14 is the same as that of the first side-push assembly 13.
[0028] By adopting the above technical solution, when the side push drive device 131 of the first side push assembly 13 drives the buffer pad 132 to move towards the first reference seat 83, the workpiece 15 is pushed tightly onto the side of the first reference seat 83 of the positioning assembly 8. Similarly, when the side push drive device 131 of the second side push assembly 14 drives the buffer pad 132 to move towards the second reference seat 84, the workpiece 15 is pushed tightly onto the side of the second reference seat 84 of the positioning assembly 8. The first side push assembly 13 and the second side push assembly 14 cooperate to push the workpiece 15 tightly from two different directions and accurately position the workpiece 15 on the positioning assembly 8. This achieves automatic positioning of workpieces 15 of different specifications and has the advantages of strong versatility, high positioning efficiency, high positioning accuracy and good positioning effect.
[0029] In this embodiment, the side thrust drive device 131 is preferably configured as a cylinder.
[0030] In one embodiment, reference is made to Figure 3As shown, the first reference base 83 and the second reference base 84 are located on the outer sides of two adjacent sides of the first base 81. The height of the second base 82 is greater than the height of the first base 81. The second side push assembly 14 is located between the first base 81 and the second base 82. The output end of the side push drive device 131 of the second side push assembly 14 faces the first base 81. The side push drive device 131 of the second side push assembly 14 drives the buffer pad 132 in the horizontal direction, thereby pushing the workpiece 15 to the side of the second reference base 84.
[0031] In another embodiment, the first reference base 83 and the second reference base 84 are respectively located on the outer sides of two adjacent sides of the first base 81. The height of the second base 82 is less than or equal to the height of the first base 81. The second side push assembly 14 is located on the side of the second base 82 away from the first base 81, and the output end of the side push drive device 131 of the second side push assembly 14 faces the second base 82. The side push drive device 131 of the second side push assembly 14 drives the buffer pad 132 in the horizontal direction to push the workpiece 15 to the side of the second reference base 84.
[0032] Through the technical solutions of the above two embodiments, the second side push assembly 14 is suitable for limiting and fixing workpieces of different specifications in the horizontal direction, so as to achieve the purpose of strong versatility.
[0033] Reference Figure 5 As shown, the first spinning assembly 9 includes a spinning drive device 91, a spinning arm 92, and a pressure plate 93. The spinning drive device 91 is mounted on the positioning table 7 with its output end facing upwards. One end of the spinning arm 92 is connected to the output end of the spinning drive device 91, and the other end of the spinning arm 92 is connected to the pressure plate 93. The structure and working principle of the second spinning assembly 10, the third spinning assembly 11, and the fourth spinning assembly 12 are the same as those of the first spinning assembly 9.
[0034] Reference Figure 2 and Figure 5As shown, by adopting the above technical solution, the spinning drive device 91 of the first spinning assembly 9 drives the rotating arm 92 to rotate downward, thereby causing the pressure plate 93 to press against the edge portion of the workpiece 15 located above. The first spinning assembly 9, the second spinning assembly 10, the third spinning assembly 11, and the fourth spinning assembly 12 sequentially surround the workpiece 15 and press against the edge portion of the workpiece 15 located above, so that the edge portions of the two workpieces 15 to be welded can be aligned vertically and tightly fitted together, so as to facilitate the welding torch 4 to accurately weld the edge joint of the two workpieces 15. When the welding torch 4 needs to weld the joint of the edge portion of the two workpieces 15 corresponding to the edge portion of the first spinning assembly 9, the spinning drive device 91 of the first spinning assembly 9 drives the rotating arm 92 to rotate upward, thereby causing the pressure plate 93 to move away from the edge portion of the workpiece 15 located above to avoid the welding torch 4, thereby ensuring that the welding torch 4 can continuously weld the edge joint of the two workpieces 15. When the welding torch 4 welds the edge portion of the two workpieces 15 corresponding to the edge portion of the first spinning assembly 9, After the joint is welded, the spinning drive device 91 of the first spinning assembly 9 drives the spinning arm 92 to rotate downwards, thereby causing the pressure plate 93 to press against the edge of the workpiece 15 located above. The second spinning assembly 10, the third spinning assembly 11, and the fourth spinning assembly 12 adopt the same avoidance method as the first spinning assembly 9 to ensure that the welding torch 4 can continuously weld the joint of the edge of the two workpieces 15. This ensures good sealing of the two workpieces 15, and the weld points at the joint are uniform in size and flat and continuous. It has the advantages of high welding efficiency and good welding effect. This solves the problem that the existing automated welding equipment on the market has uneven weld points, incomplete welding seal, and low yield of finished products because the clamping mechanism will block the welding torch from continuously welding the edge of the workpiece when clamping the workpiece. In addition, it also solves the problems of low welding efficiency, poor welding effect, low degree of automation and high labor cost of traditional manual welding of workpieces (radiators).
[0035] In this embodiment, the spinning drive device 91 is preferably configured as a rotary cylinder.
[0036] Reference Figure 6As shown, the welding torch positioning mechanism 3 includes a left-right moving component 31, a moving base 32, a front-back moving component 33, a moving frame 34, a lifting moving component 35, and a welding torch mounting bracket 36. The left-right moving component 31 is mounted on the machine base 1 and is drivenly connected to the moving base 32. The front-back moving component 33 is mounted on the moving base 32. The left-right moving component 31 drives the moving base 32 and the front-back moving component 33 to move left and right in the horizontal direction. The front-back moving component 33 is drivenly connected to the moving frame 34. The lifting moving component 35 is mounted on the moving frame 34. The front-back moving component 33 drives the moving frame 34 and the lifting moving component 35 to move back and forth in the horizontal direction. The lifting moving component 35 is drivenly connected to the welding torch mounting bracket 36. The welding torch 4 is mounted on the welding torch mounting bracket 36 and is used to weld the edge part of the workpiece that needs to be welded. The lifting moving component 35 drives the welding torch mounting bracket 36 and the welding torch 4 to move up and down.
[0037] By adopting the above technical solution, the welding torch 4, driven by the left and right moving component 31, the front and back moving component 33 and the lifting moving component 35, can move in three-dimensional space to weld and position the joint of the edge parts of two workpieces of different specifications during the welding process, and to accurately weld the joint of the edge parts of two workpieces of different specifications, so as to ensure good welding effect, high welding accuracy and high yield of the workpiece.
[0038] In this embodiment, the left-right moving component 31, the forward-backward moving component 33, and the lifting moving component 35 all include a servo motor and a linear module, with the servo motor and the linear module being connected for transmission. The specific structure of the linear module is common knowledge and will not be explained in detail here.
