[0036] The following is combined with Figure 1 to Figure 6 The utility model is further described in detail, but it is not intended to limit the utility model.

[0037] like Figure 1As shown, in one embodiment of the utility model, the battery welding clamping device comprises a top cover limiting component 1, a first clamping mechanism 4, a second clamping mechanism 5 and at least one pad 6; a clamping inner cavity 3 is arranged around the first clamping mechanism 4 and the second clamping mechanism 5; the clamping inner cavity 3 is used to place the battery to be processed; and the clamping direction of the first clamping mechanism 4 and the clamping direction of the second clamping mechanism 5 intersect; the pad 6 is arranged inside the clamping inner cavity 3; the top cover limiting component 1 is detachably connected to the first clamping mechanism 4 and / or the second clamping mechanism 5, and is arranged above the pad 6. Among them, the clamping direction of the first clamping mechanism 4 and the clamping direction of the second clamping mechanism 5 are arranged vertically.

[0038] The technical solution of the utility model adjusts the number or height of the pads according to the height of the batteries to be processed, so as to achieve the positioning and clamping of the batteries to be processed in the height direction between the top cover limiting component and the pads; thereby, it is compatible with the clamping of more batteries to be processed of different sizes and types, reduces the input of external energy power (such as electricity, gas and other power), reduces the cost, and can also ensure the stability of clamping, which is conducive to the orderly progress of subsequent welding operations; then, the first clamping mechanism and the second clamping mechanism clamp and position the batteries to be processed from different directions, thereby achieving clamping and positioning in more different directions, avoiding the shaking of the batteries to be processed during the welding process, thereby improving the stability of clamping and ensuring the orderly progress of processing.

[0039] Among them, in some embodiments, the number of the pads 6 is at least two, and they are stacked; the pads 6 can be square plates or circular plates, etc. That is, according to the height of the battery to be processed, the number or height of the pads is adjusted so that the top cover of the battery to be processed can abut against the top cover limiting component 1, thereby achieving a rapid limiting effect, thereby improving the stability of the clamping, and being suitable for processing batteries of more different sizes and types to be processed.

[0040] Specifically, in some embodiments, Figure 1 and 2 As shown, the top cover limiting component 1 is a top cover limiting plate 11; a channel 111 communicating with the clamping inner cavity 3 is provided in the middle of the top cover limiting plate 11. The top cover limiting plate 11 may be a square limiting plate or a circular limiting plate, etc. In other words, the top cover limiting plate 11 has a limiting effect of squeezing and clamping the top cover of the battery, and the channel 111 allows the pole on the top of the battery to pass through, thereby reducing the squeezing and friction effect on the pole, and ensuring the clamping and limiting effect on the top cover of the battery.

[0041] Specifically, in some embodiments, Figure 1As shown, at least one locking mechanism 2 is provided on the top cover limiting component 1, and the locking mechanism 2 is detachably connected to the second clamping mechanism 5. In other words, through the multiple locking mechanisms 2 at the side ends of the top cover limiting component 1, a multi-point clamping effect can be achieved, thereby improving the clamping stability. Figure 1 and 2 As shown in Figure 3, in some embodiments, the locking mechanism 2 includes a mounting block 21 and a movable locking assembly 22; one end of the mounting block 21 is connected to the side end of the top cover limiting component 1; and a locking groove 213 is provided on the mounting block 21; the movable locking assembly 22 includes a buckling folding rod 222 and a second connecting block 223; the second connecting block 223 is connected to the second clamping mechanism 5; one end of the buckling folding rod 222 is movably connected to the second connecting block 223; and the buckling folding rod 222 can be buckled and connected in the locking groove 213. Further, the buckling folding rod 222 is an annular folding rod or a U-shaped folding rod. In other words, the assembly stability between the top cover limiting component 1 and the second clamping mechanism 5 can be guaranteed by buckling and clamping the annular folding rod or the U-shaped folding rod in the locking groove 213, and the rapidity of the detachability of the two can realize the convenience of assembly between the top cover limiting component 1 and the second clamping mechanism 5.

[0042] Specifically, in some embodiments, Figure 2 and 3 As shown, the mounting block 21 includes a first connecting block 211 and a folding block 212 which are connected to each other obliquely (vertically); the first connecting block 211 is detachably connected to the side end of the top cover limiting component 1 by bolts; the locking groove 213 is arranged at the upper end of the folding block 212. The locking groove 213 is an arc-shaped locking groove. The folding block 212 extending outward can ensure the convenience of assembly and avoid the friction loss of the top cover limiting component 1.

[0043] Specifically, in some embodiments, Figure 2 and 3 As shown, the movable locking assembly 22 also includes a first swing block 221 and a first connecting shaft 224; one end of the first swing block 221 is rotatably connected to the second connecting block 223; the first connecting shaft 224 is fixedly connected to the first swing block 221; and the two ends of the first connecting shaft 224 are respectively connected to the two ends of the buckle folding rod 222. That is to say, when the top cover limiting component 1 is assembled with the second clamping mechanism 5, the first swing block 221 is driven to rotate toward the direction of the second connecting block 223, so that the first connecting shaft 224 and the buckle folding rod 222 are simultaneously rotated toward the locking groove 213; thereby, the buckle folding rod 222 is buckled and connected to the inner wall of the locking groove 213; and the first swing block 221 is driven to rotate downward, so that the buckle folding rod 222 and the locking groove 213 are assembled and tightened, thereby realizing the limit clamping operation; and ensuring its clamping stability.

[0044] Specifically, in some embodiments, Figure 1 and 2 As shown, the first clamping mechanism 4 includes a first clamping positioning plate 41, a first movable clamping plate 42 and a first displacement driving component 43; the first clamping positioning plate 41 and the first movable clamping plate 42 are arranged side by side; and the clamping inner cavity 3 is formed between the first clamping positioning plate 41, the first movable clamping plate 42 and the second clamping mechanism 5; the first displacement driving component 43 is drivingly connected to the first movable clamping plate 42 so that the first movable clamping plate 42 moves toward or away from the first clamping positioning plate 41. In other words, the lateral movement of the first displacement driving component 43 drives the first movable clamping plate 42, so as to realize the clamping and positioning effect between the first clamping positioning plate 41 and the first movable clamping plate 42 to adapt to the short sides or long sides of batteries to be processed of different specifications. Among them, as Figure 4 As shown, the first movable clamping plate 42 includes a first vertical plate 4201 and a first horizontal plate 4202 which are perpendicular to each other; the first vertical plate 4201 is connected to the first displacement driving component 43; and the first movable clamping plate 42 also includes a first reinforcing plate, and both side ends of the first reinforcing plate are respectively connected to the first vertical plate 4201 and the first horizontal plate 4202.

The first protruding pressing block 411 is an L-shaped first protruding pressing block. In other words, the L-shaped first protruding pressing block extending toward the clamping inner cavity 3 squeezes and limits the edge position of the top of the battery to be processed, thereby improving the clamping effect on the top cover.

[0046] Specifically, in some embodiments, Figure 2 As shown, a second protruding pressing block 421 is provided on the top of the first movable clamping plate 42; one side end of the second protruding pressing block 421 extends toward the clamping inner cavity 3; and the bottom of the second protruding pressing block 421 abuts against the battery to be processed. The second protruding pressing block 421 is an L-shaped second protruding pressing block. That is, the L-shaped second protruding pressing block extending toward the clamping inner cavity 3 squeezes and limits the edge position of the top of the battery to be processed, thereby improving the clamping effect on the top cover.

[0047] Specifically, in some embodiments, Figure 2 and 4As shown, the first displacement driving component 43 includes a second swing block 431, a second connecting shaft 432, a first clamp 433, a third connecting block 434 and a first base 44; one end of the second swing block 431 is rotatably connected to the first base 44; one end of the first clamp 433 is connected to the second connecting shaft 432; the second connecting shaft 432 is connected to the second swing block 431; the other end of the first clamp 433 is connected to one end of the third connecting block 434; the other end of the third connecting block 434 is connected to the first movable clamping plate 42. When in use, the second swing block 431 is rotated toward the inner direction of the clamping cavity 3 to make the first clamp 433 swing, so that the other end of the first clamp 433 pushes the third connecting block 434 to move horizontally, thereby realizing the first movable clamping plate 42 to move toward the first clamping positioning plate 41, so as to reduce the volume of the clamping cavity 3. Therefore, through the driving action of the second swing block 431 and the third connecting block 434, the input of external energy (such as electricity, gas, etc.) is reduced, the cost is reduced, and the stability of the clamping can be guaranteed, which is conducive to the orderly progress of subsequent welding operations. Figure 4 As shown, a first slide rail 441 is disposed on the first base 44; the first vertical plate 4201 is slidably connected to the first slide rail 441; the movement guiding function can be improved, thereby avoiding collision and damage between components.

[0048] Specifically, in some embodiments, Figure 1 and 2 As shown, the second clamping mechanism 5 includes a second clamping positioning plate 51, a second movable clamping plate 52 and a second displacement driving component 53; the second clamping positioning plate 51 and the second movable clamping plate 52 are arranged side by side; and the clamping inner cavity 3 is formed between the second clamping positioning plate 51, the second movable clamping plate 52 and the first clamping mechanism 4; the second displacement driving component 53 is drivingly connected to the second movable clamping plate 52 so that the second movable clamping plate 52 moves toward or away from the second clamping positioning plate 51. In other words, the lateral movement of the second displacement driving component 53 drives the second movable clamping plate 52, so that the second clamping positioning plate 51 and the second movable clamping plate 52 can realize the clamping and positioning effect of the short side or long side of the batteries to be processed of different specifications. Among them, as Figure 5 As shown, the second movable clamping plate 52 includes a second vertical plate 5201 and a second horizontal plate 5202 which are perpendicular to each other; the second horizontal plate 5202 is connected to the second displacement driving component 53; and the second movable clamping plate 52 also includes a third reinforcing plate, and both side ends of the third reinforcing plate are respectively connected to the second vertical plate 5201 and the second horizontal plate 5202. Further, the second clamping positioning plate 51 includes a fourth reinforcing plate and a fourth vertical plate and a fourth horizontal plate which are perpendicular to each other; both side ends of the fourth reinforcing plate are respectively connected to the fourth vertical plate and the fourth horizontal plate.

[0049] Specifically, in some embodiments, Figure 2 As shown, a third protruding pressing block 511 is provided on the top of the second clamping positioning plate 51; one side end of the third protruding pressing block 511 extends toward the clamping inner cavity 3; and the bottom of the third protruding pressing block 511 abuts against the battery to be processed. The third protruding pressing block 511 is an L-shaped third protruding pressing block. In other words, the L-shaped third protruding pressing block extending toward the clamping inner cavity 3 squeezes and limits the edge position of the top of the battery to be processed, thereby improving the clamping effect on the top cover.

[0050] Specifically, in some embodiments, Figure 2 As shown, a fourth protruding pressing block 521 is provided on the top of the second movable clamping plate 52; one side end of the fourth protruding pressing block 521 extends toward the clamping inner cavity 3; and the bottom of the fourth protruding pressing block 521 abuts against the battery to be processed. The fourth protruding pressing block 521 is an L-shaped fourth protruding pressing block. That is, the L-shaped third protruding pressing block extending toward the clamping inner cavity 3 squeezes and limits the edge position of the top of the battery to be processed, thereby improving the clamping effect on the top cover.

[0051] Specifically, in some embodiments, Figure 2 and 5 As shown, the second displacement driving component 53 includes a third swing block 531, a third connecting shaft 532, a second clamp 533, a fourth connecting block 534 and a second base 54; one end of the third swing block 531 is rotatably connected to the second base 54; one end of the second clamp 533 is connected to the third connecting shaft 532; the third connecting shaft 532 is connected to the third swing block 531; the other end of the second clamp 533 is connected to one end of the fourth connecting block 534; the other end of the fourth connecting block 534 is connected to the second movable clamping plate 52. When in use, the third swing block 531 is rotated toward the inner direction of the clamping cavity 3 to make the second clamp 533 swing, so that the other end of the second clamp 533 pushes the fourth connecting block 534 to move horizontally, thereby realizing the second movable clamping plate 52 to move toward the second clamping positioning plate 51, so as to reduce the volume of the clamping cavity 3. Therefore, through the driving action of the third swing block 531 and the fourth connecting block 534, the input of external energy power (such as electricity, gas, etc.) can be reduced, the cost can be reduced, and the stability of clamping can be guaranteed, which is conducive to the orderly progress of subsequent welding operations.

[0053] Wherein, in some embodiments, Figure 5 and 6 As shown, the second base 54 is provided with a second slide rail 541; the second horizontal plate 5202 is slidably connected to the second slide rail 541; the movement guiding function can be improved, thereby avoiding collision and damage between components.
