[0070] The present application also discloses a bending device 40, which can be used in the bending device 10 described above. For the bending device 40, the present application provides the following design:

[0071] Figure 2 is a schematic diagram of a bending device according to an embodiment of the present application, Figure 3This is a schematic diagram of a current collecting plate of an embodiment of the present application when it is not bent, combined with Figure 2-Figure 3 As shown, the present application discloses a bending device 40 for bending a current collecting plate 20, wherein the current collecting plate 20 includes a welding portion 21, a connecting portion 22 and a main body portion 23, wherein the welding portion 21, the connecting portion 22 and the main body portion 23 are connected in sequence, and when bent, the welding portion 21, the connecting portion 22 and the main body portion 23 are on the same plane.

[0072] The bending device 40 includes a bending main body bracket 41, a rotating disk 42, a fixing component 100, a first bending component 300 and a second bending component 400, wherein the rotating disk 42 is arranged on the bending main body bracket 41, and the rotating disk 42 can rotate on the bending main body bracket 41; the first bending component 300 is arranged on the bending main body bracket 41, and the first bending component 300 is used to bend the connection between the main body 23 and the connecting part 22; the second bending component 400 is arranged on the bending main body bracket 41, and the second bending component 400 is used to bend the connection between the connecting part 22 and the welding part 21; the fixing component 100 is arranged on the periphery of the rotating disk 42, and the fixing component 100 is used to fix the main body 23 of the collecting disk 20, and the rotation of the rotating disk 42 drives the fixing component 100 to move to the bottom of the first bending component 300 or the second bending component 400.

[0073] In simple terms, the main body 23 of the collecting plate 20 is first fixed on the fixing component 100, and then the rotating disk 42 rotates to drive the fixing component 100 to move to the bottom of the first bending component 300, and the first bending component 300 bends the main body 23 and the connecting portion 22 of the collecting plate 20.

[0074] Then the rotating disk 42 rotates again, driving the fixing component 100 to move to the bottom of the second bending component 400 , and the second bending component 400 bends the connecting portion 22 and the welding portion 21 of the current collecting plate 20 , thereby achieving the bending process.

[0075] Compared with the existing solution of manually bending the collecting plate 20, the present application sets a rotating plate 42, a fixed component 100, a first bending component 300 and a second bending component 400 to cooperate with each other. The fixed component 100 fixes the collecting plate 20, and the rotating plate 42 rotates to drive the fixed component 100 to the bottom of the first bending component 300 or the second bending component 400. The first bending component 300 and the second bending component 400 are used to bend the collecting plate 20 to ensure that the shape of each collecting plate 20 after bending is consistent; and when the first bending component 300 and the second bending component 400 are used to bend the collecting plate 20, the force on the collecting plate 20 is more uniform, and the collecting plate 20 will not be damaged, thereby reducing the production cost.

[0076] Moreover, the collecting plate 20 is fixed by the fixing component 100, and then the collecting plate 20 is brought under the first bending component 300 for the first bending process through the rotation of the rotating disk 42, and then brought under the second bending component 400 for the second bending process.

The I-shaped base 140 can also prevent the first fixing clamp block 121 and the second fixing clamp block 122 from being too close to each other and bending the main body 23, so as to protect the collecting plate 20.

[0084] Exemplarily, the sub-fixing components 180 include four, and the four sub-fixing components 180 are arranged at equal distances. By providing four sub-fixing components 180, four current collecting plates 20 can be fixed at the same time, thereby further improving production efficiency.

[0085] Figure 5 is a schematic diagram of a clamping component according to an embodiment of the present application, combined with Figure 5 As shown, the bending device 40 also includes a clamping component 200, and the clamping component 200 includes a clamping main body bracket 210, a clamping slide rail 220, a clamping sliding plate 230, a clamping insert rod 240 and a clamping sliding plate driving assembly 250.

[0086] The clamping main body bracket 210 is arranged on the bending main body bracket 41, the clamping slide rail 220 is arranged on the clamping main body bracket 210, the clamping sliding plate 230 is slidably connected with the clamping slide rail 220, the clamping insert rod 240 is arranged on the clamping sliding plate 230, and the clamping insert rod 240 is located on the side of the clamping sliding plate 230 close to the rotating disk 42; that is, facing between the first roller 161 and the second roller 162.

[0087] The clamping and sliding plate driving member 250 is connected to the clamping and sliding plate 230 and is used to drive the clamping and sliding plate 230 to move closer to or away from the rotating disk 42 .

[0088] The clamping rod 240 is used to extend between the first roller 161 and the second roller 162 to increase the distance between the first roller 161 and the second roller 162, thereby increasing the distance between the first fixed clamp block 121 and the second fixed clamp block 122.

[0089] Specifically, the clamping sliding plate 230 is driven forward by the clamping sliding plate driving assembly 250, and the clamping rod 240 is extended between the first roller 161 and the second roller 162, so that the distance between the first roller 161 and the second roller 162 is increased, thereby driving the distance between the first fixed clamp block 121 and the second fixed clamp block 122 to increase. At this time, the collecting plate 20 can be placed between the first fixed clamp block 121 and the second fixed clamp block 122.

[0090] Then, the clamping sliding plate 230 is driven to move backward by the clamping sliding plate driving part 250, and the clamping rod 240 is pulled out from between the first roller 161 and the second roller 162, so that the distance between the first roller 161 and the second roller 162 becomes smaller, driving the distance between the first fixed clamp block 121 and the second fixed clamp block 122 to become smaller. At this time, the collecting plate 20 can be clamped and fixed by the first fixed clamp block 121 and the second fixed clamp block 122.

[0091] Then, the sub-fixing component 180 is driven to move to the first bending component 300 by the rotation of the rotating disk 42 to perform the bending process.

[0092] Furthermore, the width of the clamping rod 240 gradually decreases along the direction toward the sub-fixing component 180, so that when the clamping rod 240 is pulled out, the first fixing clamp block 121 and the second fixing clamp block 122 will not exert a large force on the collecting plate 20 at once, thereby achieving the protection effect on the collecting plate 20.

[0093] Exemplarily, when the sub-fixing components 180 include four, the clamping and plugging rods 240 also include four. The four clamping and plugging rods 240 are equidistantly arranged on the clamping and sliding plate 230, and the four clamping and plugging rods 240 correspond one to one with the four sub-fixing components 180. The four clamping and plugging rods 240 are simultaneously inserted between the first roller 161 and the second roller 162 of the four sub-fixing components 180 to open or close the four sub-fixing components 180 at the same time, thereby ensuring the synchronization of the first fixing block 121 and the second fixing block 122, avoiding the problem of asynchrony, and improving work efficiency.

[0102] Then the first top knife driving assembly 342 drives the first top knife slide plate 343 to move downward, driving the first top knife assembly 344 to move downward; then the first folding knife driving assembly 332 drives the first folding knife assembly 333 to move forward, that is, to move in the direction of the collecting plate 20, so that the first folding knife slope 334 abuts against the bottom of the connecting portion 22, and the first pressing knife slope 326 abuts against the top of the connecting portion 22, thereby realizing the bending between the connecting portion 22 and the main body 23.

[0107] The first knife pressing assembly 320 includes a first knife pressing slide rail 321, a first knife pressing driving assembly 322 and a first knife pressing assembly 323. The first knife pressing slide rail 321 is arranged on the first bending main body bracket 310, and the length direction of the first knife pressing slide rail 321 is the vertical direction. The first knife pressing assembly 323 is slidably connected to the first knife pressing slide rail 321.

[0108] The first folding knife assembly 330 includes a first folding knife slide rail 331, a first folding knife driving coupling 332 and a first folding knife coupling 333. The first folding knife slide rail 331 is arranged on the first bending main body bracket 310, and the length direction of the first folding knife slide rail 331 is horizontal and faces the rotating disk 42; the first folding knife coupling 333 is slidingly connected to the first folding knife slide rail 331, and the first folding knife driving coupling 332 is connected to the first folding knife coupling 333, and is used to drive the first folding knife coupling 333 to move forward and backward.

[0109] The first jet assembly 350 includes a first bending air channel 351 and a first bending nozzle 352. The first bending nozzle 352 is connected to the first bending main body bracket 310, and the first bending nozzle 352 is directed upward. The first bending air channel 351 is connected to the first bending nozzle 352 for transmitting gas to be ejected from the first bending nozzle 352.

[0110] The first bending nozzle 352 is used to spray the connecting portion 22 so that the connecting portion 22 forms an angle with the main body 23 .

[0113] Compared with the method of pushing the connecting portion 22 upward by the first top knife assembly 340, the method of blowing air to the connecting portion 22 by the first bending nozzle 352 does not need to wait until the first top knife assembly 344 moves downward and returns to its original position before driving the first folding knife assembly 333 to move forward, which can improve the bending efficiency and further improve the production capacity;

[0114] Secondly, it can also avoid the situation where, after the first top knife assembly 340 moves downward, the connecting part 22 returns to the same plane with the main body 23 due to elasticity problems.

The second pressing knife coupling part 442 is arranged on the side of the second pressing knife fixing plate 441 away from the second folding knife spacer plate 435.

[0126] The end of the second pressing knife assembly 442 close to the second top knife assembly 422 is defined as a second pressing knife slope 445, and the second pressing knife slope 445 faces the second top knife assembly 422, and the angle between the second pressing knife slope 445 and the horizontal plane is 45°, and the second pressing knife slope 445 is used to abut against the side of the connecting portion 22 facing away from the sub-fixing component 180.

[0127] The end of the second top knife assembly 422 close to the second pressing knife assembly 442 is defined as a second top knife slope 424, and the second top knife slope 424 faces the second pressing knife assembly 442, and the angle between the second top knife slope 424 and the horizontal plane is 45°, and the second top knife slope 424 is used to abut against a side of the connecting portion 22 close to the sub-fixing component 180.

[0128] The side of the second folding knife part 436 close to the second top knife joint 422 is defined as a second folding knife slope 438, which is used to abut against the side of the main body 23 of the collecting plate 20 facing away from the sub-fixing component 180. The second folding knife slope 438 rotates along the folding knife shaft 437 as the axis, and is used to rotate the welding portion 21 of the collecting plate 20 downward along the connection between the welding portion 21 and the connecting portion 22, so that the welding portion 21 of the collecting plate 20 and the connecting portion 22 are bent.

[0129] Illustratively, the second folding knife vertical driving assembly 433 drives the second folding knife slide 432 to move downward, thereby driving the second pressing knife slope 445 of the second pressing knife assembly 442 to abut against the side of the connecting portion 22 facing away from the sub-fixing component 180; then the second top knife driving assembly 423 drives the second top knife assembly 422 to move forward, so that the second top knife slope 424 is used to abut against the side of the connecting portion 22 close to the sub-fixing component 180 to fix the connecting portion 22.

[0130] Then the second folding knife rotation driving assembly 434 drives the second folding knife part 436 to rotate along the folding knife rotation axis 437, and the second folding knife inclined surface 438 rotates the welding portion 21 of the current collecting plate 20 downward along the connection between the welding portion 21 and the connecting portion 22, so that the welding portion 21 of the current collecting plate 20 is bent with the connecting portion 22, so as to complete the bending between the welding portion 21 and the connecting portion 22.

[0131] The second pressing blade assembly 442 adopts a rotating pressing method, which can avoid arc bending at the connection between the welding part 21 and the connecting part 22 compared to directly pressing, thereby ensuring the success rate of bending and improving the concentricity of the collecting plate 20 after bending.

In this way, when the second folding knife component 436 presses down the welding portion 21, the second folding knife assembly 430 can achieve excessive bending, which can reserve a little rebound angle for the welding portion 21 to avoid bending failure.

[0135] Fig.14 is a schematic diagram of an embodiment of the present application, including a second press knife power output module and a second press knife control module, combined with Fig.14 As shown, further, the second press blade assembly 442 can also be changed into electromagnetic material.

Then, the second folding knife power output module 443 energizes the second folding knife assembly 442, and the connecting portion 22 can be adsorbed on the second folding knife inclined surface 445 to prevent the elastic recovery of the connecting portion 22 from causing the second top knife assembly 422 to damage the collecting plate 20.
