[0028] Figure 1 , is a schematic diagram of the structure of a battery tab welding device in one embodiment.
[0029] In this embodiment, the battery tab welding device is used to compress multiple layers of battery tabs and perform laser welding on the compressed battery tabs. Figure 1 As shown, the battery tab welding device includes a clamping mechanism 10 and a welding mechanism 20 (not shown).
[0030] like Figure 2 As shown, the clamping mechanism 10 includes a clamping assembly 120 and a driving assembly 140 (not shown); the clamping assembly 120 is located above the battery tab, and the driving assembly 140 can drive the clamping assembly 120 to abut against the surface of the battery tab.
[0031] The clamping mechanism 10 may be a functional module that is located above the battery tab in the vertical direction and can abut against the surface of the battery tab, and performs floating clamping on the battery tab to eliminate the gap between multiple layers of battery tabs without crushing the battery tab. The clamping assembly 120 may be a functional assembly that is arranged below the driving assembly 140 in the vertical direction and can directly contact the surface of the battery tab, and performs floating clamping on the battery tab under the drive of the driving assembly 140 to eliminate the gap between multiple layers of battery tabs. The driving assembly 140 may be a functional assembly that is arranged above the clamping assembly 120 in the vertical direction and cooperates with the clamping assembly 120, and can apply a clamping force to the clamping assembly 120.
[0032] Alternatively, if Figure 2 As shown, the clamping assembly 120 includes a clamping block 1220 and a clamping mounting seat 1240; the clamping block 1220 is arranged on the clamping mounting seat 1240, and the bottom surface of the clamping block 1220 can be pressed against the surface of the battery ear under the action of the driving assembly 140, and the cross-sectional dimension of the clamping block 1220 decreases toward the bottom surface of the clamping block 1220 in the vertical direction. By gradually reducing the cross-sectional dimension of the clamping block 1220 in the vertical direction, the battery ear can be floated and clamped to eliminate the gap between the multiple layers of battery ears, while improving the problem of large space occupied and heavy material weight of the clamping block 1220, and can improve the efficiency of the coordinated use of the clamping assembly 120 and the driving assembly 140.
[0033] In one embodiment, the ratio of the bottom size of the clamping block 1220 to the surface size of the battery lug is less than M, and the value range of M is: 0<M<1; the center line of the bottom surface of the clamping block 1220 coincides with the center line of the surface of the battery lug. By constraining the size and position matching relationship between the clamping block 1220 and the battery lug, the contact area between the clamping block 1220 and the battery lug can be sufficient while ensuring the uniformity of the floating clamping effect on the battery lug, effectively eliminating the gap between the multiple layers of battery lugs and reducing damage to the surface of the battery lug.
[0034] The welding mechanism 20 includes a welding assembly 220 (not shown) and a welding auxiliary assembly 240 ; the laser beam output by the welding assembly 220 can pass through the welding auxiliary assembly 240 to weld the battery tab to the tab cover.
[0035] The welding mechanism 20 may be a functional module that is arranged above the clamping mechanism 10 in the vertical direction and used in conjunction with the clamping mechanism 10, and can apply a laser beam to the battery tab after the battery tab is clamped to weld the battery tab to the tab cover. The welding assembly 220 may be a functional assembly that is arranged above the welding auxiliary assembly 240 in the vertical direction and can weld the battery tab using a laser beam. The welding auxiliary assembly 240 may be a functional assembly that is arranged below the welding assembly 220 in the vertical direction and can assist the welding assembly 220 in the welding process of the battery tab.
[0036] Optionally, the welding assembly 220 may be a laser welding head. Figure 3 As shown, the welding auxiliary assembly 240 includes an upper dust suction pipe 2420 and a lower dust suction pipe 2440. The dust suction pipe 2420 is arranged at the entrance of the welding assembly 220 in the vertical direction, and the lower dust suction pipe 2440 is located above the battery pole ear. The upper dust suction pipe 2420 and the lower dust suction pipe 2440 are both curved pipes with corners. The gas outlet direction of the upper dust suction pipe 2420 is opposite to that of the lower dust suction pipe 2440. The upper dust suction pipe 2420 and the lower dust suction pipe 2440 arranged at different heights in the vertical direction can suck out the slag and other flying dust generated in the laser welding process from different heights, thereby achieving a deep dust removal effect and improving the dust removal efficiency.
[0037] In one embodiment, a groove is provided on one side of the clamping mount 1240 close to the clamping block 1220, and a protrusion is provided on one side of the clamping block 1220 close to the clamping mount 1240, and the protrusion is abutted against the groove. Through the mutual interlocking arrangement of the groove and the protrusion, the matching stability between the clamping block 1220 and the clamping mount 1240 can be ensured, while the matching accuracy between the clamping block 1220 and the clamping mount 1240 is improved, thereby improving the floating clamping effect between the clamping block 1220 and the clamping mount 1240, ensuring the uniformity of the floating clamping action on the battery pole ear, effectively eliminating the gap between the multiple layers of battery pole ears and reducing the damage to the surface of the battery pole ears.
[0038] Alternatively, if Figure 2As shown, the clamping assembly 120 also includes a limit plate 1260 and a floating member 1280. The limit plate 1260 is arranged on the side of the clamping block 1220, and the limit plate 1260 abuts against the side of the groove. The clamping mounting seat 1240 is provided with a floating mounting hole, and the floating member 1280 abuts against the clamping block 1220 through the floating mounting hole; specifically, a plurality of floating mounting holes are arranged at intervals in the groove, and any floating member 1280 abuts against the protrusion through a floating mounting hole; through the cooperation of the limit plate 1260, the floating member 1280 and the floating mounting hole, the cooperation stability and cooperation accuracy between the clamping block 1220 and the clamping mounting seat 1240 can be further improved, and the uniformity of the floating clamping action between the clamping block 1220 and the clamping mounting seat 1240 can be ensured, thereby improving the uniformity and stability of the floating clamping action on the battery pole ear, and achieving the elimination of the gap between the multi-layer battery pole ears without causing damage to the surface of the battery pole ear under the clamping action.
[0039] In one embodiment, Figure 1 As shown, the battery tab welding device further includes a main body support mechanism 40 and an air intake mechanism 30 ; along the vertical direction, the clamping mechanism 10 is installed below the main body support mechanism 40 , and the air intake mechanism 30 is installed on the side of the main body support mechanism 40 .
[0040] The main body support mechanism 40 may be a supporting and mounting functional module disposed above the clamping mechanism 10 in the vertical direction and capable of carrying the clamping mechanism 10, the welding mechanism 20 and the air intake mechanism 30. The air intake mechanism 30 may be a functional module installed on the side of the main body support mechanism 40 and outputting three-way shielding gas to the main body support mechanism 40 to protect the laser welding process.
[0041] When welding multi-layer battery tabs, the cooperation relationship among the clamping mechanism 10, the welding mechanism 20, the air intake mechanism 30 and the main support mechanism 40 can achieve a floating clamping effect on the battery tabs while further ensuring the welding effect of the battery tab laser welding process.
[0042] The battery pole lug welding device provided in the present application, when welding multi-layer battery pole lugs, the clamping mechanism 10 located above the battery pole lug to be welded, under the action of the driving component 140, drives the clamping block 1220 (arranged on the clamping mounting seat 1240) in the clamping component 120 to press against the surface of the battery pole lug to be welded. After the battery pole lug to be welded is clamped, the welding component 220 arranged above the welding auxiliary component 240 in the welding mechanism 20 outputs a laser beam and passes through the welding auxiliary component 240 to weld the battery pole lug to be welded to the lug cover plate, thereby realizing the clamping and laser welding of any layer of battery pole lugs, improving the problem that the gaps between the multi-layer battery pole lugs are large and the welding quality of the multi-layer battery pole lugs cannot be guaranteed, thereby improving the welding stability of the battery pole lugs while improving the welding efficiency of the battery pole lugs, effectively ensuring the battery processing accuracy.
[0043] The present application also provides a processing device, which includes the battery tab welding device as in the above embodiment.
[0044] The division of the various modules in the above-mentioned battery tab welding device is only for illustration. In other embodiments, the battery tab welding device can be divided into different modules as needed to complete all or part of the functions of the above-mentioned battery tab welding device.
[0045] The battery pole ear welding device and processing equipment provided in the above-mentioned embodiments, when welding multi-layer battery pole ears, the clamping mechanism located above the battery pole ear to be welded, under the action of the driving component, drives the clamping block (arranged on the clamping mounting seat) in the clamping assembly to press against the surface of the battery pole ear to be welded. After the battery pole ear to be welded is clamped, the welding assembly arranged above the welding auxiliary assembly in the welding mechanism outputs a laser beam and passes through the welding auxiliary assembly to weld the battery pole ear to be welded to the pole ear cover plate, thereby realizing the clamping and laser welding of any layer of battery pole ears, improving the problem that the gaps between the multi-layer battery pole ears are large and the welding quality of the multi-layer battery pole ears cannot be guaranteed, thereby improving the welding stability of the battery pole ears while improving the welding efficiency of the battery pole ears, effectively ensuring the battery processing accuracy, and having important economic value and promotion and practical value.
