Description

Technical Field

[0001] This utility model belongs to the field of welding technology, and more specifically, it relates to a welding clamping mechanism and welding device. Background Technology

[0002] When welding the first component and the second component, the first component is usually placed on a support base first, and then the second component is placed on the upper surface of the first component. A clamping device is then used to press the second component firmly onto the first component. This clamping device typically has a through-hole through which the laser welds from one side of the second component. However, in some cases, the second component may tip over when placed on the first component, causing the clamping device to fail to press the second component firmly against the first component. Utility Model Content

[0008] The clamping drive is disposed on the support base and is drivenly connected to the clamping member. When the first member is placed on the second member, the clamping drive drives the clamping member to press the first member against the second member.

Therefore, to address the problem of tipping over when the second component is placed on the first component, the second component can be placed on the support base first, then the first component can be placed on the second component, and then the clamping member can press the first component onto the second component. After the first and second components are pressed together, the support base can be rotated in a vertical plane to a welding position, so that the second component can be welded from one side of the second component through the through hole on the support base.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0034] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In some descriptions of utility models, "a plurality of" means two or more, unless otherwise explicitly specified.

[0036] This application provides a welding clamping mechanism that can be applied to a welding device. The welding clamping mechanism is used to clamp a first part and a second part to be welded, so that the welding mechanism in the welding device can weld the second part onto the first part.

[0037] In some implementations, the first component may be a battery and the second component may be a bus.

[0038] See Figure 1 A welding clamping mechanism includes a base 100 and a clamping structure 300. The clamping structure 300 is connected to the base 100 and can rotate relative to the base 100 in a vertical plane.

[0039] Further, see Figure 2 and Figure 3 The clamping structure 300 may include a support base 320, a clamping member 330, and a clamping drive member 340.

[0040] The support 320 is connected to the base 100 and can rotate relative to the base 100 in a vertical plane.

[0041] The support base 320 is used to support the second component 500, and a through hole 321 is provided on the support base 320 corresponding to the welding area of ​​the second component 500.

[0042] The clamping drive 340 is disposed on the support base 320, and the clamping drive 340 is driven to connect with the clamping member 330. When the first member 400 is placed on the second member 500, the clamping drive 340 drives the clamping member 330 to clamp the first member 400 onto the second member 500.

[0043] Specifically, before loading, the support base 320 is rotated in the vertical plane to a horizontal position. Then, the second component 500 is placed on the support base 320, which supports the second component 500. Next, the first component 400 is placed on the second component 500, and the clamping drive 340 drives the clamping member 330 to press the second component 500 against the first component 400. After the first component 400 and the second component 500 are pressed against the support base 320 by the clamping member 330, the support base 320 is rotated in the vertical plane, so that the support base 320 in the clamping structure 300 is rotated to the welding position, that is, the position where the support base 320 is opposite to the welding mechanism of the welding device, so that the welding mechanism can weld the second component 500 and the first component 400 through the through hole 321 on the support base 320.

[0044] In other words, in this application, the support base 320 can rotate in a vertical plane relative to the base 100. Therefore, to address the problem of tipping over when the second component 500 is placed on the first component 400, the second component 500 can be placed on the support base 320 first, and then the first component 400 can be placed on the second component 500. Next, the clamping member 330 can press the first component 400 onto the second component 500. After the first component 400 and the second component 500 are pressed together, the support base 320 can be rotated in a vertical plane until it is in a welding position. The second component 500 and the first component 400 can then be welded together from one side of the second component 500 through the through hole 321 on the support base 320. This method facilitates the loading and assembly of the first component 400 and the second component 500, and ensures that the first component 400 and the second component 500 can be pressed together.

[0045] For example, in some embodiments, when the welding mechanism of the welding apparatus is positioned above the welding clamping mechanism, the support base 320 can rotate 180°. Specifically, after the first component 400 and the second component 500 are clamped onto the support base 320, the support base 320 can rotate another 180°, causing the support base 320 of the clamping structure 300 to rotate relative to the welding mechanism, allowing the welding mechanism to weld the first component 400 and the second component 500 through the through hole 321 on the support base 320.

[0046] Furthermore, the welding clamping mechanism may also include a rotating platform 200, which is connected to the base 100.

[0047] The clamping structure 300 also includes a mounting base 310, which is connected to the rotating platform 200 and can rotate in a vertical plane under the action of the rotating platform 200. A support base 320 is connected to the mounting base 310, a clamping drive 340 is connected to the mounting base 310, and a clamping member 330 is arranged opposite to the support base 320. A 90° angle is formed between the mounting base 310 and the support base 320.

[0048] The rotating platform 200 can rotate in the vertical plane by driving the mounting base 310, so that the mounting base 310 drives the support base 320, the clamping drive 340 and the clamping member 330 connected to the clamping drive 340 to rotate in the vertical plane.

[0049] Mounting base 310 facilitates the installation of drive component 340 and allows 330 to press the first component 400 and the second component 500 onto support base 320.

[0050] See Figure 2 The clamping structure 300 may also include a positioning element 350, which is connected to the mounting base 310 and located between the support base 320 and the clamping element 330. The side of the positioning element 350 is provided with a contour groove 351, which is used to position the first component 400 placed on the second component 500.

[0051] Specifically, during the process of placing the first component 400 on the second component 500, the contour groove 351 on the positioning component 350 can position and limit the first component 400 to ensure that the first component 400 can be accurately placed on the second component 500, and to limit the first component 400 during the pressing process of the clamping component 330 to prevent the first component 400 from shifting during the pressing process.

[0052] In some embodiments, to avoid interference between the clamping member 330 and the first component 400 during the process of clamping the first component 400 onto the second component 500, the height of the positioning member 350 may be lower than the height of the workpiece, that is, the surface of the positioning member 350 near the clamping member 330 is lower than the surface of the first component 400 near the clamping member 330.

[0053] Furthermore, a first position adjustment structure 360a may be provided between the positioning member 350 and the mounting base 310. The first position adjustment structure 360a enables the positioning member 350 to move between the clamping member 330 and the support base 320 to adjust the position of the positioning member 350.

[0054] It is understandable that when the height of the first component 400 is different, the position of the positioning component 350 on the mounting base 310 can be adjusted by the first position adjustment structure 360a. This allows the positioning component 350 to move away from or closer to the support base 320, so that the contour groove 351 of the positioning component 350 can be positioned and limited close to the center of the workpiece, ensuring the accuracy of positioning and the stability of limiting.

[0055] In some embodiments, the first position adjustment structure 360a may include a plurality of mounting holes on the mounting base 310 spaced apart along the distance between the positioning member 350 and the support base 320, and the positioning member 350 may select appropriate mounting holes for assembly according to the height of the first component 400.

[0056] In addition, to facilitate the installation of the positioning member 350 and the mounting hole of the support base 320, the positioning member 350 may be connected to a first connecting seat 370a, which is connected to the mounting hole of the support base 320.

[0057] Furthermore, a second position adjustment structure 360b may be provided between the clamping drive member 340 and the mounting base 310. The second position adjustment structure 360b allows the clamping drive member 340 to move closer to or further away from the support base 320, thereby adjusting the position of the clamping drive member 340. It can be understood that by adjusting the clamping drive member 340 to move closer to or further away from the support base 320, the distance between the clamping member 330 and the support base 320 can be adjusted.

[0058] When the heights of the first component 400 are different, the distance between the clamping member 330 and the support base 320 can be adjusted by the second position adjustment structure 360b to accommodate the clamping between the first component 400 and the second component 500 of different heights. It is understood that in some embodiments, to reduce costs, the clamping drive member 340 may be a cylinder, and the stroke of the cylinder is generally fixed, that is, the movement stroke of the clamping member 330 is also generally fixed. Therefore, by adjusting the distance between the clamping member 330 and the support base 320, the clamping member 330 and the support base 320 can be adapted to clamp the first component 400 and the second component 500 of different sizes.

[0059] In some embodiments, the second position adjustment structure 360b may include a plurality of mounting holes spaced apart on the mounting base 310 along the distance between the positioning member 350 and the support base 320. The clamping drive member 340 may select appropriate mounting holes for assembly according to the height of the first component 400 and the second component 500, so that the clamping member 330 can clamp the first component 400 and the second component 500.

[0060] In addition, to facilitate the installation of the clamping drive 340 and the mounting hole of the support 320, the clamping drive 340 may be connected to a second connecting seat 370b, which is connected to the mounting hole of the support 320.

[0061] See Figure 2 The clamping structure 300 may also include a sliding structure 380, with the positioning element 350 and the clamping drive element 340 respectively mounted on the mounting base 310 via the sliding structure 380.

[0062] Understandably, when adjusting the positions of the positioning member 350 and the clamping drive member 340, the positioning member 350 and the clamping drive member 340 can slide on the mounting base 310 through the sliding structure 380 to facilitate the adjustment of the positions of the positioning member 350 and the clamping drive member 340. After the positioning member 350 and the clamping drive member 340 slide to the determined adjustment position, the first position adjustment structure 360a can fix the positioning member 350 and the mounting base 310, and the second position adjustment structure 360b can fix the clamping drive member 340 and the mounting base 310.

[0063] When the positioning member 350 is connected to the first connecting seat 370a, the positioning member 350 can be connected to the sliding structure 380 through the first connecting seat 370a. When the pressing drive member 340 is connected to the second connecting seat 370b, the pressing drive member 340 can be connected to the sliding structure 380 through the second connecting seat 370b.

[0064] In some embodiments, the sliding structure 380 may include a slide rail 381 and a first slider 382 and a second slider 383 slidably disposed on the slide rail 381. A positioning member 350 may be connected to the first slider 382, ​​and a pressing drive member 340 may be connected to the second slider 383. It is understood that since the positioning member 350 and the pressing drive member 340 have the same adjustment direction, they can share the same slide rail 381 in the sliding structure 380, thereby saving costs and making the pressing structure 300 more compact.

[0065] See Figure 2 The clamping structure 300 may further include a detector 390, which is located on one side of the positioning member 350 and is used to detect whether the positioning member 350 has positioned the first component 400. It is understood that in the welding clamping structure 300 of this application, the second component 500 is first placed on the support base 320, and then the first component 400 is placed on the second component 500. Therefore, when the detector 390 detects that the first component 400 is positioned on the positioning member 350, it means that both the first component 400 and the second component 500 are fully loaded. At this time, the clamping member 330 can clamp the first component 400 onto the second component 500.

[0066] Furthermore, in some embodiments, a connector 391 may be provided between the detector 390 and the positioning member 350, enabling the detector 390 to move synchronously with the positioning member 350. It is understood that the connector 391 facilitates the installation and fixation of the detector 390, and since the positioning member 350 can adjust its position according to the size of the first component 400, the detector 390 maintains synchronous movement with the positioning member 350 through the connector 391, ensuring that the detector 390 can always detect the first component 400 at the contour groove 351.

[0067] Furthermore, in order to facilitate the detector 390 to detect the first component 400 that is positioned and limited in the contour groove 351, the positioning component 350 may also be provided with a detection hole 352 that communicates with the contour groove 351, and the detector 390 detects the workpiece through the detection hole 352.

[0068] See Figure 3 In some embodiments, the support base 320 may also be provided with a positioning part 322, which is used to position the second component 500.

[0069] It is understandable that when feeding the first component 400 and the second component 500, the second component 500 is first fed onto the support base 320, and the positioning part 322 on the support base 320 positions the second component 500. Then, the first component 400 is fed onto the second component 500, and the contour groove 351 on the positioning member 350 positions the first component 400, thereby achieving precise feeding of the first component 400 and the second component 500.

[0070] For example, when the first component 400 is a battery and the second component 500 is a busbar, the contour groove 351 can be an arc-shaped groove, which positions the side of the battery, and the positioning part 322 can be a positioning post, which cooperates with the hole on the busbar for positioning.

[0071] Furthermore, in some embodiments, the sidewall of the through hole 321 provided in the support 320 may also be provided with an air hole 323, which is used to introduce inert gas into the through hole 321.

[0072] It is understandable that when welding the first component 400 and the second component 500 with a laser, an inert gas, i.e. a protective gas, needs to be introduced. Therefore, the clamping structure 300 in the welding clamping mechanism of this application is provided with a vent 323 to allow the introduction of inert gas, so that the welding clamping mechanism can be applied to various types of welding devices. For example, it can be used in conjunction with welding mechanisms that do not have the function of introducing inert gas to weld the first component 400 and the second component 500, thereby improving the applicability of the welding clamping mechanism.

[0073] See Figure 1The base 100 may include a first substrate 110 and a second substrate 120. The second substrate 120 is disposed on the first substrate 110 and extends in a vertical direction. The rotating platform 200 is disposed on the side of the second substrate 120.

[0074] Specifically, in some embodiments, the first substrate 110 can serve as the base element of the welding clamping mechanism. The welding clamping mechanism can be set at a predetermined position in the welding device through the first substrate 110. The rotating platform 200 is set on the side of the second substrate 120 extending in the vertical direction, which can facilitate the rotating platform 200 to drive the clamping structure 300 to rotate in the vertical plane through the mounting base 310.

[0075] Optionally, a 90° angle may be formed between the first substrate 110 and the second substrate 120.

[0076] In addition, this application also provides a welding apparatus, including a welding mechanism and a welding clamping mechanism according to the embodiments of this application. The welding mechanism is set according to the rotation path of the support 320. When the rotating platform 200 rotates, the support 320 can rotate to a position opposite to the welding mechanism. The welding mechanism can weld the first component 400 and the second component 500 through the through hole 321 of the support 320.

[0077] The welding mechanism can be a laser welding mechanism. The welding mechanism can be located above the welding clamping mechanism. After the clamping member 330 clamps the first component 400 and the second component 500 onto the support base 320, the rotating platform 200 can drive the entire clamping structure 300 to rotate 180°, so that the support base 320 rotates to be directly below the welding mechanism. The laser emitted by the welding mechanism welds the first component 400 and the second component 500 through the through hole 321.

[0078] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of some utility models should be included within the protection scope of some utility models.
