[0020] The exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.
[0021] Figure 1 Schematic diagram of the structure of a laser device welding device (hereinafter referred to as welding device) of the embodiment of the utility model. Figure 1-2As shown, the welding device 10 includes a first clamping portion 11, a second clamping portion 12, a first supporting portion 13 and a second supporting portion 14, and a loading platform 15. The first clamping portion 11 is connected to the first supporting portion 13, and the second clamping portion 12 is connected to the second supporting portion 14. The first supporting portion 13 and the second supporting portion 14 are both located on the first side of the loading platform 15. The first clamping portion 11 and the second clamping portion 12 are both used to clamp different materials of the laser device. The first supporting portion 13 is used to support the first clamping portion 11, and the second supporting portion 14 is used to support the second clamping portion 12. The loading platform 15 is used to carry the laser device. During welding, the first supporting portion 13 is located between the second supporting portion 14 and the loading platform 15. The welding gun generally maintains a fixed angle with the horizontal plane. In such a welding device, since the first support part and the second support part are at different heights during welding, the welding gun will not be blocked from the viewing angle, so that the two welding guns on both sides of the loading platform can weld different welding points of the materials clamped by the first clamping part and the second clamping part at the same time, which saves welding time and improves welding efficiency. Such a structure is also relatively simple, does not require complex modifications to the equipment, and is relatively cost-effective.
[0022] Specifically, the laser device may be a butterfly laser, and the materials of the laser device include a lens, an optical isolator, an optical filter, an optical fiber, and the like.
[0023] In an embodiment of the utility model, the welding device also includes a first welding gun 16 and a second welding gun 17, which are used to weld the material of the laser device; during welding, the first welding gun 16 and the second welding gun 17 are respectively located on opposite sides of the loading platform 15, and the first welding gun 16 and the second welding gun 17 form a first angle and a second angle with the horizontal plane respectively, and the positions of the first welding gun 16 and the second welding gun 17 are higher than the positions of the first support portion 13 and the second support portion 14. Specifically, there are 4 points that need to be welded when welding the material of the laser device, and there are 2 welding points on both sides of the material, so 2 welding guns are required. Specifically, the first welding gun 16 and the second welding gun 17 are both laser welding guns. In order to ensure the welding effect of the first welding gun 16 and the second welding gun 17, the first welding gun 16 and the second welding gun 17 must maintain a certain angle with the horizontal plane, so that the laser power emitted by the welding gun can be optimized and the welding effect can be better. Specifically, the first angle and the second angle can be Figure 1 Angle A and angle B are both acute angles.
[0024] Since the first welding gun 16 and the second welding gun 17 should maintain a certain angle with the horizontal plane, and the positions of the first welding gun 16 and the second welding gun 17 are higher than the first support part 13 and the second support part 14, if the positions of the first support part 13 and the second support part 14 are not set reasonably, when the first welding gun and the second welding gun are welding at the same time, the laser emitted by one of the welding guns will be easily blocked and interfered, which is not conducive to the precise and efficient welding of the first welding gun and the second welding gun at the same time. Therefore, the first support part 13 and the second support part 14 in the embodiment of the utility model are arranged up and down to avoid the transmission path of the laser emitted by the welding gun from being blocked and interfered. Specifically, the welding device also includes a first welding gun control part and a second welding gun control part, the first welding gun control part is connected to the first welding gun for controlling the position of the first welding gun, and the second welding gun control part is connected to the second welding gun for controlling the position of the second welding gun.
[0025] Specifically, the first welding gun control unit and the second welding gun control unit both include a first slide rail 161 and a first position control unit 162. The first position control unit 162 is disposed on the first slide rail 161 and can move along the first slide rail 161. Specifically, the first position control unit 162 is a 6-axis coupling platform.
[0026] Specifically, the first welding gun 16 and the first supporting portion 13 are arranged on different sides of the loading platform 15, as shown in FIG. Figure 3 As shown, the first welding gun 16 is in the first direction of the loading platform, and the first support portion 13 and the second support portion 14 are in the second direction of the loading platform 15; the first direction and the second direction are different. Specifically, the first direction and the second direction are perpendicular, for example, the first direction and the second direction can be respectively Figure 1 In order to provide a better field of view for the first welding gun during welding, the projections of the first support portion and the second support portion on the horizontal plane at least partially overlap; in this way, the first support portion and the second support portion are aligned as much as possible in the height direction, and the field of view of the first welding gun in the direction facing the laser device is blocked as little as possible. Specifically, the horizontal plane in the embodiment of the utility model specifically refers to Figure 1 The plane in which the x-direction and y-direction lie.
[0027] In the embodiment of the utility model, the first clamping portion 11 includes a main body portion 111 and a bent portion 112. The included angle between the extending direction of the bent portion 112 and the extending direction of the main body portion 111 (for example Figure 4The middle angle C) is an obtuse angle. Specifically, the second clamping part 12 can be a long strip structure. Since the size of the materials of the laser device is relatively small (millimeter level), if the first clamping part 11 and the second clamping part 12 are both long strip structures, when placing different materials, the distance between the first clamping part 11 and the second clamping part 12 will be relatively close, which may interfere with each other, which is not conducive to the position adjustment and fixation of different materials. Therefore, in order to avoid the first clamping part 11 and the second clamping part 12 from influencing each other when placing materials, the first clamping part 11 adopts a structure with a bending part. Specifically, the first clamping part 11 and the second clamping part 12 both pick up the materials by adsorbing the materials. Specifically, the first clamping part 11 and the second clamping part 12 both include suction nozzles.
[0028] In the embodiment of the utility model, the welding device further includes a first support control unit 18 and a second support control unit 19. The first support control unit 18 is connected to the first clamping unit 11 through the first support unit 13 to control the position of the first clamping unit 11. The second support control unit 19 is connected to the second clamping unit 12 through the second support unit 14 to control the position of the second clamping unit 12. Specifically, the first support control unit 18 and the second support control unit 19 can be a six-axis coupling platform, which can be in three directions (for example Figure 1 The first clamping part and the second clamping part are moved and rotated in the x, y, and z directions. In this way, the positions of the first clamping part and the second clamping part can be flexibly adjusted.
[0029] Specifically, Figure 1 As shown, the first support portion 13 includes a first bar structure 131, one end of which is connected to the first clamping portion 11, and the second support portion 14 includes a second bar structure 141, one end of which is connected to the second clamping portion 12. Specifically, the first support portion 13 also includes a first connecting portion 132, and the second support portion 14 also includes a second connecting portion 142: the other end of the first bar structure 131 is connected to the first support control portion 18 through the first connecting portion 132, and the other end of the second bar structure 141 is connected to the second support control portion 19 through the second connecting portion 142.
[0030] In the embodiment of the utility model, the welding device further includes a first image acquisition unit 20 and a second image acquisition unit 21, the first image acquisition unit 20 is used to observe the welding condition of the first welding gun 16, and the second image acquisition unit 21 is used to observe the welding condition of the second welding gun 17. Specifically, the first image acquisition unit 20 and the second image acquisition unit 21 are located on opposite sides of the loading platform. Specifically, the first image acquisition unit 20 and the first welding gun 16 are located on the same side of the loading platform, and the second image acquisition unit 21 and the first welding gun 17 are located on the same side of the loading platform. Specifically, the first image acquisition unit 20 is connected to the first welding gun 16, and the second image acquisition unit 21 is connected to the second welding gun 17. The welding device further includes a first image acquisition control unit and a second image acquisition control unit, the first image acquisition control unit is connected to the first image acquisition unit 20, and is used to control the position of the first image acquisition unit 20, and the second image acquisition control unit is connected to the second image acquisition unit 21, and is used to control the position of the second image acquisition unit 21. When the first welding gun 16 and the first image acquisition unit 20 are arranged together, the first image acquisition control unit and the first welding gun control unit can be the same component; when the second welding gun 17 and the second image acquisition unit 21 are arranged together, the second image acquisition control unit and the second welding gun control unit can be the same component. Specifically, the first image acquisition unit 20 and the second image acquisition unit 21 can be CCDs.
[0031] In the embodiment of the utility model, Figure 2 As shown, the welding device further includes a third support portion 22, a fourth support portion 23, a third clamping portion 24 and a fourth clamping portion 25, the third clamping portion 24 is connected to the third support portion 22, the fourth clamping portion 25 is connected to the fourth support portion 23, the third support portion 22 and the fourth support portion 23 are both located on the second side of the loading platform 15 opposite to the first side, the third clamping portion 24 and the fourth clamping portion 25 are both used to clamp different materials of the laser device, the third support portion 22 is used to support the third clamping portion 24, and the fourth support portion 23 is used to support the fourth clamping portion 25: during welding, the third support portion 22 is located between the fourth support portion 23 and the loading platform 15. Since the heights of the third support portion 22 and the fourth support portion 23 are different during welding, the laser emitted by the welding gun will not be blocked or interfered in the visual angle, and the materials clamped by the third clamping portion 24 and the fourth clamping portion 25 are conveniently welded, which saves welding time and improves welding efficiency. Such a structure is also relatively simple, does not require complex modifications to the equipment, and is relatively cost-saving.
[0032] Specifically, the projections of the third support portion 22 and the fourth support portion 23 on the horizontal plane at least partially overlap, which can provide a better field of view for the welding gun during welding and improve welding accuracy.
[0033] In the embodiment of the utility model, the third clamping part 24 includes a main body 241 and a bending part 242, and the angle between the extension direction of the bending part 242 and the extension direction of the main body 241 is an obtuse angle. The purpose of the structural design of the main body and the bending part of the third clamping part 21 is similar to the purpose of the structural design of the main body and the bending part of the first clamping part 11, which is not described in detail here. Specifically, the first clamping part 11 and the second clamping part 12 both pick up the material by adsorbing the material. Specifically, the third clamping part 24 and the fourth clamping part 25 both include a suction nozzle. It should be noted that the first clamping part 11, the second clamping part 12, the third clamping part 24 and the fourth clamping part 25 can also be other structures besides the suction nozzle, as long as the structure can clamp the material.
[0034] In the embodiment of the utility model, the welding device further includes a third support control unit 26 and a fourth support control unit 27.

Specifically, the third support control unit 26 and the fourth support control unit 27 can be a six-axis coupling platform.
[0035] It should be noted that the first support control part 18, the second support control part 19, the third support control part 26 and the fourth support control part 27 can be other structures besides the six-axis coupling platform, such as a drive motor, etc.; as long as the position adjustment of the first clamping part 11, the second clamping part 12, the third clamping part 24 and the fourth clamping part 25 can be achieved.
[0036] Specifically, Figure 3 to Figure 4 As shown, the third support portion 22 includes a third bar structure 221, one end of which is connected to the third clamping portion 24, and the fourth support portion 23 includes a fourth bar structure 231, one end of which is connected to the fourth clamping portion 25. Specifically, the third support portion 22 also includes a third connecting portion 222, and the fourth support portion 23 also includes a fourth connecting portion 232; the other end of the third bar structure 221 is connected to the third support control portion 26 through the third connecting portion 222, and the other end of the fourth bar structure 231 is connected to the fourth support control portion 27 through the fourth connecting portion 232.
