Abstract
Description
Technical Field
[0001] This application relates to the field of laser welding technology, and more particularly to a fixing device and laser welding equipment. Background Technology
[0002] In the battery manufacturing process, a crucial step is welding the battery electrodes to the PCB copper sheets. Laser welding has advantages such as minimal welding deformation and excellent welding results. Therefore, laser welding equipment is commonly used to laser weld the battery electrodes to the PCB copper sheets. In traditional laser welding equipment, to avoid interference between the laser and the welded parts and reduce energy loss, the clamping components of the fixing device are often designed as cantilever structures. When clamping the welded parts using the cantilever structure, the insufficient rigidity of the cantilever structure can easily lead to insufficient clamping of the welded parts, resulting in welding defects such as incomplete soldering, detachment, misalignment, and insufficient soldering. Utility Model Content
[0003] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide a fixing device that can improve the welding yield.
[0004] This application also provides a laser welding device.
[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:
[0006] A fixing device according to a first aspect of this application is applied to a laser welding equipment. The laser welding equipment has a first direction. The fixing device includes: a clamping mechanism for clamping a workpiece to be welded, the clamping mechanism including a base; and a pressing mechanism including a pressing member for pressing the workpiece to be welded. The pressing member and the clamping mechanism are spaced apart along the first direction. The pressing member includes a main structure and a pressing head structure. The main structure and the base are spaced apart along the first direction. The pressing head structure is connected to one end of the main structure near the base along the first direction. The main structure has a first laser avoidance hole penetrating the main structure along the first direction. The pressing head structure has a second laser avoidance hole penetrating the pressing head structure along the first direction. The first laser avoidance hole and the second laser avoidance hole are spaced apart and connected along the first direction, and a laser simultaneously passes through the first laser avoidance hole and the second laser avoidance hole. In the first direction, the projections of the main structure and the pressing head structure on the base are located within the range of the projection of the main structure on the base.
[0007] The clamping device of this application has the following advantages:
[0008] In the clamping device of this application, the workpiece to be welded can be fixed on the base of the clamping mechanism to clamp it. Then, the workpiece is pressed by the clamping member of the clamping mechanism. Since the pressure head structure of the clamping member is connected to the end of the main structure near the base along the first direction, and the projections of the main structure and the pressure head structure on the base are within the range of the projection of the main structure on the base in the first direction, when the clamping member applies pressure to the workpiece, the pressure head structure can be prevented from becoming a cantilever structure. This reduces the stress on the pressure head structure, thereby increasing its structural strength and reducing the pressure loss on the workpiece. This ensures that the workpiece can be clamped and reduces the occurrence of false welds. The possibility of welding is further enhanced by the fact that the main structure is provided with a first laser avoidance hole that extends through the first direction, and the pressure head structure is provided with a second laser avoidance hole that extends through the first direction. The first laser avoidance hole and the second laser avoidance hole are spaced apart and connected along the first direction, and the laser passes through both the first laser avoidance hole and the second laser avoidance hole simultaneously. Thus, when laser welding is performed on the workpiece, the laser can pass through both the first laser avoidance hole and the second laser avoidance hole simultaneously, so as to avoid interference from the pressure member on the laser passage, reduce the energy loss of laser welding, thereby improving the welding effect of laser welding and improving the structural strength of the weld. Therefore, the pressure device of this application can reduce the probability of welding defects during the welding process of the workpiece.

[0039] Reference Figure 1 , Figure 2 , Figure 4 as well as Figure 5 As shown, the fixing device 10 involved in the embodiment of this application is applied to a laser welding equipment. The laser welding equipment has a first direction x. The fixing device 10 includes a clamping mechanism 100 and a pressing mechanism 200.
[0040] Specifically, the clamping mechanism 100 is used to clamp the workpiece to be welded, and the clamping mechanism 100 includes a base 110; the pressing mechanism 200 includes a pressing member 210, which is used to press the workpiece to be welded. The pressing member 210 and the clamping mechanism 100 are spaced apart along a first direction x. The pressing member 210 includes a main structure 211 and a pressing head structure 212. The main structure 211 and the base 110 are spaced apart along the first direction x. The pressing head structure 212 is connected to the end of the main structure 211 near the base 110 along the first direction x. The main structure 211 is provided with a pressing head structure 212 along the first direction x. A first laser avoidance hole 2111 penetrates the main body structure 211 in the first direction x, and a second laser avoidance hole 2121 penetrates the pressure head structure 212 in the first direction x. The first laser avoidance hole 2111 and the second laser avoidance hole 2121 are spaced apart and connected in the first direction x, and the laser passes through both the first laser avoidance hole 2111 and the second laser avoidance hole 2121 simultaneously. In the first direction x, the projections of the main body structure 211 and the pressure head structure 212 on the base 110 are located within the range of the projection of the main body structure 211 on the base 110.
[0041] It should be noted that the first direction x is Figure 1 , Figure 2 as well as Figure 4 The direction indicated by x in the middle.
[0042] In the clamping device of this application, the workpiece to be welded can be fixed on the base 110 of the clamping mechanism 100 to clamp the workpiece, and then the workpiece is clamped by the clamping member 210 of the clamping mechanism 200. Since the pressure head structure 212 of the clamping member 210 is connected to the end of the main structure 211 near the base 110 along the first direction x, and the projections of the main structure 211 and the pressure head structure 212 on the base 110 in the first direction x are within the range of the projection of the main structure 211 on the base 110, when the clamping member 210 applies pressure to the workpiece, the pressure head structure 212 can be prevented from becoming a cantilever structure, thereby reducing the stress on the pressure head structure 212, improving the structural strength of the pressure head structure 212, and reducing the pressure loss of the clamping member 210 on the workpiece, so as to ensure that the workpiece can be clamped and reduce the welding pressure. The possibility of incomplete welding is mitigated by the fact that the main structure 211 is provided with a first laser avoidance hole 2111 extending along the first direction x, and the pressure head structure 212 is provided with a second laser avoidance hole 2121 extending along the first direction x. The first laser avoidance hole 2111 and the second laser avoidance hole 2121 are spaced apart and connected along the first direction x, and the laser passes through both the first laser avoidance hole 2111 and the second laser avoidance hole 2121 simultaneously. Thus, when laser welding is performed on the workpiece, the laser can pass through both the first laser avoidance hole 2111 and the second laser avoidance hole 2121 simultaneously, so as to avoid interference from the pressure member 210 on the laser passage, reduce the energy loss of laser welding, thereby improving the welding effect of laser welding and improving the structural strength of the weld. Therefore, the pressure device of this application can reduce the probability of welding defects during the welding process of the workpiece.
[0043] Referring to Figure 4, the central axis of the first laser avoidance hole 2111 coincides with the central axis of the second laser avoidance hole 2121.
[0044] In this embodiment, when the laser is directed at the workpiece to be welded, it passes through the first laser avoidance hole 2111 and the second laser avoidance hole 2121 in sequence. Since the central axis of the first laser avoidance hole 2111 coincides with the central axis of the second laser avoidance hole 2121, when the laser enters the second laser avoidance hole 2121 through the first laser avoidance hole 2111, the possibility of interference between the laser center and the hole wall of the second laser avoidance hole 2121 can be reduced, thus reducing the energy loss of laser welding. At the same time, when the central axis of the first laser avoidance hole 2111 coincides with the central axis of the second laser avoidance hole 2121, the pressure head structure 212 can be located directly below the main structure 211 along the first direction x. In this way, the stress on the pressure head structure 212 can be reduced to the greatest extent.
[0045] Continue to refer to Figure 4As shown, the main structure 211 includes a first connecting part 2112 and a second connecting part 2113. The second connecting part 2113 extends along the first direction x, and both ends of the second connecting part 2113 along the first direction x are connected to the first connecting part 2112 and the pressure head structure 212, respectively. The first laser avoidance hole 2111 is formed on the first connecting part 2112.
[0046] In this embodiment, since the second connecting portion 2113 extends along the first direction x, and both ends of the second connecting portion 2113 along the first direction x are respectively connected to the first connecting portion 2112 and the pressure head structure 212, the pressure head structure 212 is positioned directly below the first connecting portion 2112 along the first direction x. This reduces the stress on the pressure head structure 212. When the first connecting portion 2112 transmits pressure to the pressure head structure 212, the damage caused by the pressure applied by the pressure head structure 212 to the workpiece can be reduced. The pressure head structure 212 is located directly below the first connecting part 2112 along the first direction x, and the first laser avoidance hole 2111 is opened on the first connecting part 2112. Therefore, the laser can be avoided through the first laser avoidance hole 2111, so that the laser can pass through the first laser avoidance hole 2111 to irradiate into the second laser avoidance hole 2121, and then irradiate onto the workpiece through the second laser avoidance hole 2121, so as to realize laser welding of the workpiece.
[0047] Continue to refer to Figure 4 As shown, the laser welding equipment also has a second direction y, which intersects with the first direction x, and the width of the second connecting part 2113 in the second direction y gradually decreases along the first direction x toward the base 110.
[0048] It should be noted that the second direction y is Figure 4 The direction indicated by y in the middle.
[0049] In this embodiment, when the laser irradiates the workpiece through the first laser avoidance hole 2111 and the second laser avoidance hole 2121, the width of the second connecting part 2113 in the second direction y gradually decreases towards the base 110 along the first direction x. Therefore, the obstruction of the laser by the second connecting part 2113 can be reduced, further reducing the energy loss of the laser and improving the welding effect.
[0050] Continue to refer to Figure 4 As shown, there are multiple second connecting portions 2113, which are arranged around the central axis of the second laser avoidance hole 2121 to define an avoidance space 213 between the multiple second connecting portions 2113. The avoidance space 213 is connected to the first laser avoidance hole 2111 and the second laser avoidance hole 2121 at both ends along the first direction x.
[0051] Specifically, in this embodiment, there are two second connecting portions 2113, which are respectively disposed on opposite sides of the central axis of the second laser avoidance hole 2121, so as to define an avoidance space 213 between the two second connecting portions 2113.
[0052] In this embodiment, since multiple second connecting portions 2113 are arranged around the central axis of the second laser avoidance hole 2121, the stability of the connection relationship between the first connecting portion 2112 and the pressure head structure 212 can be improved through the multiple second connecting portions 2113. When the first connecting portion 2112 transmits pressure to the pressure head structure 212, the structural strength of the pressure head structure 212 can be improved, thereby improving the clamping effect on the welded part. Furthermore, since the avoidance space 213 between the multiple second connecting portions 2113 is connected to the first laser avoidance hole 2111 and the second laser avoidance hole 2121 at both ends along the first direction x, the laser irradiated into the clamping member 210 can be avoided through the avoidance space 213, so that the laser can irradiate into the second laser avoidance hole 2121 through the first laser avoidance hole 2111, and further irradiate the welded part through the second laser avoidance hole 2121, reducing the possibility of interference between the laser and the clamping member 210 and improving the laser welding effect.
[0053] Specifically, refer to Figures 1 to 3 As shown, in this embodiment, the laser welding equipment also has a third direction z, which intersects with the second direction y and the first direction x respectively, and the third direction z is... Figure 5 The direction indicated by z, i.e. the third direction z, is the length direction of the welded part. There are multiple clamping parts 210, which are arranged along the third direction z. Each clamping part 210 is used to clamp the welded part, so as to improve the clamping effect on the welded part by using multiple clamping parts 210.
[0054] Reference Figure 3 As shown, the clamping mechanism 200 also includes a first driving member 220, and the clamping member 210 also includes a connecting structure 214. The connecting structure 214 extends along the first direction x, and one end of the connecting structure 214 along the first direction x is connected to the first driving member 220. The other end of the connecting structure 214 along the first direction x is connected to the end of the main body structure 211 away from the pressure head along the first direction x. The first driving member 220 is used to drive the connecting structure 214 to move along the first direction x.
[0055] In this embodiment, the connecting structure 214 can be driven to move along the first direction x by the first driving member 220, so that the connecting structure 214 drives the main body structure 211 connected to it to move along the first direction x, thereby realizing the movement of the clamping member 210 along the first direction x, and further realizing the clamping member 210 clamping the welded part.
[0056] Specifically, refer to Figure 3 As shown, in this embodiment, the clamping mechanism 200 further includes a frame 230, a fifth drive member 240, and a second connecting member 250. The frame 230 extends along the first direction x and is disposed near the base 110. The first drive member 220 is connected to the end of the frame 230 away from the base 110 along the first direction x. The fifth drive member 240 is connected to the second connecting member 250, and the second connecting member 250 is connected to the output end of the first drive member 220. The connecting structure 214 is connected to the output end of the fifth drive member 240. Thus, the second connecting member 250 can be driven to move along the first direction x by the first drive member 220. The second connecting member 250 drives the fifth driving member 240 to move along the first direction x, and the fifth driving member 240 drives the connecting structure 214 to move along the first direction x, so as to realize the movement of the clamping member 210 along the first direction x. At the same time, after the clamping member 210 moves along the first direction x under the action of the first driving member 220, the fifth driving member 240 can also drive the connecting structure 214 to move along the first direction x, so as to drive the clamping member 210 to make fine adjustments in the first direction x, thereby adjusting the pressure of the clamping member 210 on the welded part and improving the clamping effect of the welded part.
[0057] Reference Figure 5 as well as Figure 6 As shown, the base 110 includes a base body 111 and a limiting part 112. The limiting part 112 is connected to one end of the base body 111 along the first direction x near the clamping member 210 and protrudes from the base body 111 along the first direction x. The clamping mechanism 100 also includes a clamping member 120. The clamping member 120 and the limiting part 112 are spaced apart along the second direction y to define a clamping space 113.
[0058] In this embodiment, the workpiece to be welded can be placed on the base body 111. Since the limiting part 112 protrudes from the base body 111 along the first direction x, and the clamping member 120 and the limiting part 112 are spaced apart along the second direction y, a clamping space 113 is defined. In this way, the workpiece to be welded can be clamped by the limiting part 112 and the clamping member 120 in the clamping space 113, thereby fixing the workpiece to be welded.
[0059] Specifically, refer to Figure 5As shown, in this embodiment, there are multiple clamping members 120, which are spaced apart along the third direction z. There are multiple limiting parts 112, which are spaced apart along the third direction z. Each clamping member 120 is spaced apart from a limiting part 112 along the second direction y. In this way, the fixing effect on the welded parts can be improved by the cooperation of multiple clamping members 120 and multiple limiting parts 112.
[0060] Specifically, refer to Figure 6 As shown, in this embodiment, the clamping mechanism 100 further includes a sixth driving member 170, which is connected to the clamping member 120 and is used to drive the clamping member 120 to move along the second direction y, so as to achieve the clamping of the workpiece by the clamping member 120.
[0061] Reference Figure 7 As shown, the clamping mechanism 100 also includes a second driving member 130 and a first connecting member 140. The base 110 and the clamping member 120 are both connected to the first connecting member 140. The second driving member 130 is connected to the first connecting member 140, and the second driving member 130 is used to drive the first connecting member 140 to rotate around the first direction x.
[0062] In this embodiment, the first connecting member 140 can be driven to rotate around the first direction x by the second driving member 130, so that the first connecting member 140 drives the base 110 and the clamping member 120 to rotate around the first direction x, thereby driving the welded part to rotate around the first direction x by the base 110 and the clamping member 120, so as to realize the angle adjustment of the welded part, thereby satisfying the welding angle adjustment of the welded part.
[0063] Reference Figure 5 As shown, the clamping mechanism 100 also includes a third driving member 150 and a fourth driving member 160. Both the third driving member 150 and the fourth driving member 160 are connected to the base 110. The third driving member 150 is used to drive the base 110 to move along a third direction z, and the fourth driving member 160 is used to drive the base 110 to move along a second direction y.
[0064] Specifically, refer to Figure 5As shown, in this embodiment, the clamping mechanism 100 further includes a third connecting member 180 connected to the third driving member 150 and a fourth connecting member 190 connected to the fourth driving member 160. The third driving member 150 is used to drive the third connecting member 180 to move along a third direction z, and the fourth driving member 160 is used to drive the fourth connecting member 190 to move along a second direction y. The fourth driving member 160 is connected to the third connecting member 180, and the second driving member 130 is connected to the fourth connecting member 190. Thus, when the third driving member 150 drives the third connecting member 180 to move along a third direction z, the fourth driving member 160 can be driven by the third connecting member 160. The base 110 and clamping member 120 move along the third direction z, and the fourth driving member 160 drives the fourth connecting member 190 to move along the third direction z. The fourth connecting member 190 further drives the second driving member 130 to move along the third direction z, thereby realizing the movement of the base 110 and clamping member 120 along the third direction z, and realizing the movement of the welded part in the third direction z. When the fourth driving member 160 drives the fourth connecting member 190 to move along the second direction y, the fourth connecting member 190 can drive the second driving member 130 to move along the second direction y, thereby realizing the movement of the base 110 and clamping member 120 along the second direction y, and realizing the movement of the welded part in the second direction y.
[0065] In this embodiment, the base 110 can be moved along the third direction z by the third driving member 150 and along the second direction y by the fourth driving member 160, so as to realize the movement of the base 110 in the second direction y and the third direction z, so that the welded part fixed on the base 110 can be positioned at a distance from the clamping member 210 along the first reverse extension by adjusting the position, so that the clamping member 210 can clamp the welded part, and at the same time, the welded part fixed on the base 110 can be positioned at the laser cover position by adjusting the position, so as to facilitate the subsequent laser welding of the welded part.
