Those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0033] Reference is made below to Figures 1 to 5 Describe a tab processing device for an electric core according to an embodiment of the present invention.

[0034] Reference is made to Figures 1 to 5 As shown, a tab processing device for an electric core according to an embodiment of the present invention includes a frame 100, a lifting part 200, a driving part 300, and a processing assembly 400.

[0035] Among them, the rack 100 can be horizontally provided with a placement plate 104 for placing the battery cell 500. The rack 100 is provided with a bearing part 101, and the top surface of the bearing part 101 is used to bear the tab 501. The lifting part 200 is disposed on the rack 100 in a liftable manner. The driving part 300 is disposed on the rack 100 and connected to the lifting part 200 to drive the lifting part 200 to lift. The driving part 300 can be an oil cylinder, a cylinder, an electric push rod or a motor screw mechanism, etc., as long as it can drive the lifting part 200 to lift.

[0036] The processing assembly 400 is disposed on the lifting part 200. The processing assembly 400 includes a cutting part 401, a punching structure 402 and a material pressing structure 403. The material pressing structure 403 is located above the bearing part 101. The material pressing structure 403 is used to press against the upper surface of the tab 501 to cooperate with the bearing part 101 to fix the tab 501. The material pressing structure 403 can elastically expand and contract vertically, that is, when the material pressing structure 403 is subjected to a vertical external force, it can be elastically compressed vertically, and after the external force is eliminated, it can be elastically restored.

[0037] Among them, when the material pressing structure 403 does not press against the tab 501, the bottom ends of the cutting part 401 and the punching structure 402 are both higher than the bottom end of the material pressing structure 403. When the lifting part 200 descends to make the material pressing structure 403 press against the tab 501 and the lifting part 200 continues to descend, the material pressing structure 403 compresses, so that the cutting part 401 can move down to one side of the bearing part 101 to cut the part of the tab 501 protruding from one side of the bearing part 101, and the punching structure 402 can move down to punch the tab 501.

[0038] In the present utility model, when it is necessary to cut the tab 501 of the battery cell 500 and process the hole positions, the tab 501 of the battery cell 500 is placed on the top surface of the bearing part 101, and then the driving part 300 is used to drive the lifting part 200 to descend. Since the bottom ends of the cutting part 401 and the punching structure 402 are both higher than the bottom end of the material pressing structure 403 when the material pressing structure 403 does not abut against the tab 501, the material pressing structure 403 will first press against the top surface of the tab 501 to fix the tab 501. When the lifting part 200 continues to descend, the material pressing structure 403 cannot continue to descend and will be elastically compressed, avoiding interference with the continuous descent of the cutting part 401 and the punching structure 402. When the cutting part 401 continues to descend to one side of the bearing part 101, the part of the tab 501 protruding from one side of the bearing part 101 can be cut. When the bottom end of the punching structure 402 descends below the bottom surface of the tab 501, the hole position processing of the tab 501 can be realized. The processing is convenient, time-saving and labor-saving, and only one device is needed, occupying less land and having lower costs.

[0039] It should be noted that the cutting and hole processing can be carried out simultaneously, or the cutting can be done first and then the hole processing, or the hole processing can be done first and then the cutting, which is based on the heights of the bottom ends of the cutting part 401 and the punching structure 402. The cutting part 401 can include a connecting block and a cutting knife provided at the bottom end of the connecting block, and the connecting block is used to connect the frame 100. Of course, the cutting part 401 can also be an integral cutting knife, and the cutting knife is directly installed on the frame 100. The cutting part 401 can also be other suitable structures, which will not be elaborated here.

[0040] In some embodiments of the present invention, as Figures 1 to 5 shown, the material pressing structure 403 includes a plurality of springs 404 and a material pressing block 405. The plurality of springs 404 are arranged side by side on the lifting part 200 and extend vertically. The material pressing block 405 is provided at the bottom ends of all the springs 404, and the material pressing block 405 is used to press the tab 501. For example, the bottom surface of the material pressing block 405 can be adapted to the tab 501. When the lifting part 200 descends to press the tab 501 and continues to descend, the spring 404 is compressed, and then an elastic acting force can be applied to the material pressing block 405, and the material pressing block 405 can elastically press the tab 501, so that the fixing effect on the tab 501 is better, and it can also avoid the tab 501 being damaged due to excessive rigid impact force. In addition, when the spring 404 is compressed, it can avoid interfering with the continuous descent of the cutting part 401 and the punching structure 402, so as to facilitate the cutting part 401 to cut the tab 501 and the punching structure 402 to process holes in the tab 501.

[0041] It should be noted that in some other embodiments of the present invention, the material pressing structure 403 can also be other structures. For example, it can also be an elastic rubber block.

[0042] In some embodiments of the present invention, as Figures 3 to 5As shown, the blank holder 405 is slidably mounted vertically on the frame 100. The bottom end of the spring 404 abuts against the blank holder 405, that is, the spring 404 is not directly connected to the blank holder 405 but only abuts against it. The cutting part 401 is formed with a first abutting part 406, and the blank holder 405 is formed with a second abutting part 407. When the blank holder 405 does not press the tab 501, the bottom end of the second abutting part 407 abuts against the top end of the first abutting part 406. When the blank holder 405 presses the tab 501 and compresses the spring 404, the second abutting part 407 is separated from the first abutting part 406. When the blank holder 405 does not press the tab 501, due to its own gravity and the elastic force of the spring 404, the bottom end of the second abutting part 407 can abut against the top end of the first abutting part 406. Through the limiting action of the first abutting part 406, the blank holder 405 can be prevented from falling. When the blank holder 405 presses the tab 501 and the lifting part 200 continues to descend, causing the spring 404 to compress, the cutting part 401 follows the lifting part 200 and continues to descend. In this case, the second abutting part 407 is separated from the first abutting part 406. After the processing is completed, when the lifting part 200 rises to the top end of the first abutting part 406 abutting against the bottom end of the second abutting part 407, the second abutting part 407 can be driven to rise, thereby driving the blank holder 405 to rise and separate from the tab 501. The operation is simple and convenient, and the spring 404 does not need to be welded to the blank holder 405, so the processing is more convenient, and it is convenient to repair or replace the spring 404 or the blank holder 405, and the practicability is better.

[0043] In some embodiments of the present invention, as Figures 3 to 5 shown, the punching structure 402 includes a plurality of punching pins. The plurality of punching pins are arranged side by side on the lifting part 200 and extend vertically. The punching pins correspond to the springs 404 one by one, and the springs 404 are sleeved on the outside of the corresponding punching pins. The blank holder 405 is provided with a plurality of through holes 408 penetrating vertically. The through holes 408 correspond to the punching pins one by one, and the through holes 408 are for the corresponding punching pins to pass through. When the blank holder 405 presses the tab 501 and the lifting part 200 continues to descend, the spring 404 compresses, and the bottom end of the punching pin passes through the corresponding through hole 408 to punch the tab 501. The processing is simple and convenient, and the punching pin can guide the spring 404 to prevent the spring 404 from bending radially. In addition, the through hole 408 of the blank holder 405 can also guide the punching pin to prevent the punching pin from deflecting during punching, resulting in a decline in punching quality.

[0044] It should be noted that in some other embodiments of the present invention, the punching structure 402 can also be other structures. For example, it can also be a drill bit. When the drill bit descends, it rotates at the same time, and can also drill the tab 501.

[0045] In some embodiments of the present invention, as Figures 3 to 5As shown, the lifting part 200 is connected with a detachable mounting part 409, a plurality of punches are arranged on the mounting part 409, and the top of the spring 404 abuts the mounting part 409. For example, the mounting part 409 can be mounted on the frame 100 by a plurality of fasteners, or can be clamped on the frame 100. In this way, when the cutting part 401, the pressing structure 403 and the punching structure 402 need to be installed, the cutting part 401, the pressing structure 403 and the punching structure 402 can be installed on the mounting part 409 in advance, and then the mounting part 409 can be installed on the frame 100, which makes the assembly simpler, more time-saving and labor-saving. In addition, the top of the spring 404 abuts the mounting part 409, but is not welded with the mounting part 409, so when the spring 404 needs to be repaired or replaced, the operation is more convenient, more time-saving and labor-saving.

[0046] In some embodiments of the present invention, Figure 5 As shown, the bearing part 101 is provided with a clearance hole 102 which passes through from top to bottom corresponding to the punching needle. When the punching needle punches, the bottom end of the punching needle can extend into the clearance hole 102, so that not only the punching effect is better, but also the punching needle can be prevented from touching the bearing part 101 and causing damage.

[0047] It should be noted that, in some other embodiments of the present invention, the frame 100 may be provided with a material receiving box below the clearance hole 102, and the material receiving box is used to receive waste materials generated during the punching process.

[0048] In some embodiments of the present invention, Figures 3 to 5 As shown, the bearing part 101 is provided with a sinking platform 103, and the cutting part 401 can move down to the side of the bearing part 101 away from the sinking platform 103. The sinking platform 103 is used to place the end of the battery cell 500 close to the pole ear 501, and the side wall of the sinking platform 103 is used to abut the side wall of the battery cell 500. When the pole ear 501 needs to be processed, the end of the battery cell 500 close to the pole ear 501 is placed in the sinking platform 103, and the side wall of the end of the battery cell 500 close to the pole ear 501 abuts the side wall of the sinking platform 103. In this embodiment, the sinking platform 103 is provided, and the side wall of the sinking platform 103 can position the pole ear 501, so that not only the cutting part 401 can cut the pole ear 501 more accurately, but also the punching structure 402 can process the hole position of the pole ear 501 more accurately, and the processing quality is better.

[0049] In some embodiments of the present invention, Figure 1 and Figure 2As shown in the figure, the rack 100 is horizontally provided with a placement plate 104 for placing the battery cell 500, and the placement plate 104 can be adjusted to move vertically; and / or, the placement plate 104 can be adjusted to move in the first horizontal direction, and the first horizontal direction is perpendicular to the side wall of the sunken platform 103. The plate surface of the placement plate 104 is horizontally arranged, and the placement plate 104 is used for placing the battery cell 500.

[0050] In this embodiment, the placement plate 104 can be adjusted to move vertically, and thus the height of the placement plate 104 can be adjusted according to the thickness dimension of the battery cell 500, so that the distance between the bottom surface of the tab 501 and the bottom surface of the battery cell 500 is approximately equal to the distance between the top surface of the placement plate 104 and the top surface of the bearing part 101. Furthermore, more accurate positioning of the battery cell 500 and the tab 501 can be achieved, so that the processing quality of the tab 501 is better. In addition, the placement plate 104 can also be adjusted to move in a direction perpendicular to the side wall of the sunken platform 103, and thus the position of the placement plate 104 in the first horizontal direction can be appropriately adjusted according to the dimension in the length direction of the battery cell 500. Furthermore, more accurate positioning of the battery cell 500 and the tab 501 can be achieved, so that the processing quality of the tab 501 is better.

[0051] It should be noted that there are various ways to adjust the placement plate 104 vertically and in the first horizontal direction. For example, when the placement plate 104 is connected to the rack 100 through fasteners, kidney-shaped holes can be provided at the connection position between the placement plate 104 and the rack 100. The kidney-shaped holes extend vertically or in the first horizontal direction, and the fasteners are passed through the kidney-shaped holes. When the fasteners are at different positions in the length direction of the kidney-shaped holes, movement adjustment can be performed. In addition, movement adjustment can also be performed through an oil cylinder or a cylinder, etc.

[0052] In some embodiments of the present utility model, as Figure 1 and Figure 2 shown, two limiting strips 105 are provided on the top surface of the placement plate 104. The two limiting strips 105 are arranged in the second horizontal direction and can be adjusted to move in the second horizontal direction. The limiting strips 105 extend in the first horizontal direction, and the second horizontal direction is perpendicular to the first horizontal direction. The two limiting strips 105 are used to limit the two sides in the width direction of the battery cell 500 to prevent the battery cell 500 from moving randomly during the processing of the tab 501. Moreover, the two limiting strips 105 can be adjusted to move in the second horizontal direction, and thus can be applicable to battery cells 500 with different widths, and the practicability is better.

[0053] It should be noted that there are various ways to move and adjust the limiting strip 105 along the second horizontal direction. For example, when the limiting strip 105 is connected to the placement plate 104 through a fastener, a kidney-shaped hole can be provided on the limiting strip 105 or the placement plate 104. The kidney-shaped hole extends along the second horizontal direction, and the fastener passes through the kidney-shaped hole. When the fastener is at different positions in the length direction of the kidney-shaped hole, the movement adjustment can be carried out. In addition, the movement adjustment can also be carried out through an oil cylinder or a cylinder, etc.

[0054] In some embodiments of the present invention, as Figure 3 and Figure 4 shown, guiding notches 410 are provided at the corner positions on both sides of the opposite ends of the cutting part 401 and the pressure block 405. The guiding notches 410 penetrate vertically, and the frame 100 is provided with a guiding part 411 corresponding to the guiding notches 410. The guiding part 411 fits on the surface of the guiding notches 410. For example, the guiding notch 410 can include two side walls, one of which is parallel to the first horizontal direction and the other is parallel to the second horizontal direction, and the guiding part 411 fits on the two side walls of the guiding notch 410. In this embodiment, the provision of the guiding notches 410 and the guiding part 411 can cooperate to guide the cutting part 401 and the pressure block 405 as a whole, avoiding the cutting part 401 and the pressure block 405 from swinging in the horizontal direction during the lifting and lowering process, thereby making the cutting and hole processing quality of the tab 501 better.

[0055] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those of ordinary skill in the art.
