Description

Technical Field

[0001] The utility model relates to the technical field of batteries, in particular to an ear cutting device and a battery. Background Art

[0002] After the heat sealing of the aluminum plastic film of the soft package battery is completed, it is necessary to cut the lengths of the ears at both ends of the soft package battery into lengths that meet the production requirements through an ear cutting device to avoid the problem of too long ear lengths.

[0003] The current ear cutting device mainly includes a conveyor belt and a cutting assembly. The conveyor belt is located between two adjacent cutting assemblies. The soft package battery is transported to a position corresponding to the cutting assembly through the conveyor belt, that is, at this time, the soft package battery is located in the middle of two adjacent cutting assemblies; then, the cutting assembly is moved in the direction close to the ear so that the ear can extend into the cutting position of the cutting assembly, so as to facilitate cutting the length of the ear through the cutting assembly.

[0004] However, when the soft package battery has a position or angle deviation on the conveyor belt, that is, at this time, the ear is no longer directly opposite to the cutting position, resulting in an inclined misalignment between the ear and the cutting position, so that the ear cannot be directly inserted into the cutting position or even cannot be inserted into the cutting position, leading to problems of poor cutting quality of the ear or even inability to cut.

[0046] To make the technical problems solved by the present utility model, the technical solutions adopted, and the achieved technical effects clearer, the technical solutions of the present utility model will be further described below with reference to the drawings and through specific implementation manners.

[0047] The current tab cutting device mainly includes a conveyor belt and a cutting assembly. The conveyor belt is located between two adjacent cutting assemblies. The soft-pack battery is transported by the conveyor belt to a position corresponding to the cutting assembly, that is, at this time, the soft-pack battery is located between two adjacent cutting assemblies; then, the cutting assembly is moved in the direction close to the tab so that the tab can extend into the cutting position of the cutting assembly, so as to facilitate cutting the length of the tab by the cutting assembly; however, when the soft-pack battery has a position or angle offset on the conveyor belt, that is, at this time, the tab is no longer directly opposite to the cutting position, resulting in an inclined misalignment between the tab and the cutting position, so that the tab cannot be inserted directly into the cutting position or even cannot be inserted into the cutting position, resulting in poor cutting quality of the tab or even inability to cut.

[0048] For this reason, as Figure 1As shown, in this embodiment, a tab cutting device and a battery 50 are proposed. The battery 50 includes a battery body 51 and two tabs 52. Two tabs 52 are connected to the battery body 51 on opposite sides along the X axis, one is a positive tab and the other is a negative tab. The lengths of the positive tab and the negative tab are cut based on the tab cutting device, so that the length of the tab 52 meets the length required by production. In this embodiment, the battery 50 is specifically a soft-pack battery, and the above-mentioned battery body 51 specifically refers to other structures in the soft-pack battery except the two tabs 52, such as an outer shell and a battery cell disposed in the outer shell.

[0049] Specifically, Figure 1 As shown, the tab cutting device includes a frame 10, a cutting assembly 30, a conveying member 20 and an adjusting assembly 40; wherein the conveying member 20 is used to convey the battery 50 to the middle of two adjacent cutting assemblies 30 along the Y axis; the cutting assembly 30 is slidably connected to the frame 10 along the X axis; one end of the adjusting assembly 40 is fixedly connected to the frame 10, and the other end of the adjusting assembly 40 is located on the conveying member 20; the adjusting assembly 40 is used to adjust the tab 52 of the battery 50 to the cutting position facing the cutting assembly 30. wherein one cutting assembly 30 is used to cut the length of one tab 52, so as to improve the cutting efficiency of the tab 52.

[0050] Compared with the prior art, the tab cutting device in this embodiment is additionally provided with an adjusting component 40 for adjusting the swing position and / or placement angle of the tab 52 of the deviation-correcting battery 50 on the conveying member 20 before cutting the tab 52; the battery 50 is first conveyed along the Y axis to a position corresponding to the cutting component 30 by the conveying member 20, that is, at this time, the battery 50 is located between two adjacent cutting components 30; and then the tab 52 of the battery 50 on the conveying member 20 is adjusted by the adjusting component 40 to the cutting position of the cutting component 30 so that the tab 52 of the battery 50 is aligned with the tab 52 of the battery 50. The cutting position of the cutting component 30 is arranged opposite to each other, so as to ensure that when the cutting component 30 moves toward the pole ear 52, the pole ear 52 can extend into the cutting position along the X-axis to facilitate the cutting component 30 to cut the pole ear 52; before cutting the pole ear 52, the placement position and / or placement angle of the pole ear 52 of the battery 50 on the conveying member 20 is adjusted and corrected by the adjustment component 40, so that there is no tilt or misalignment between the pole ear 52 and the cutting position, thereby ensuring the smooth cutting of the pole ear 52 and the good cutting quality of the pole ear 52.

[0051] Specifically, the adjustment component 40 adjusts the placement position and / or placement angle of the battery 50 on the conveyor 20 so that when the cutting component 30 slides along the X-axis close to the battery 50, the pole ear 52 of the battery 50 can extend directly into the cutting position of the cutting component 30 along the X-axis, so that the cutting component 30 can cut the length of the pole ear 52.

[0052] It should be noted that the battery 50 is first conveyed along the Y-axis to the middle of two adjacent cutting assemblies 30 by the conveying member 20, that is, the above-mentioned adjusting assembly 40 is arranged in the middle of two adjacent cutting assemblies 30. That is to say, at this time, the battery 50 and the two adjacent cutting assemblies 30 are on the same straight line in the X-axis direction; then, the cutting assembly 30 is moved along the X-axis towards the direction close to the ear 52, so that the cutting assembly 30 will not interfere with the conveying work of the conveying member 20 for the battery 50, ensuring the normal conveying of the battery 50; and during the process of the cutting assembly 30 moving along the X-axis towards the direction close to the ear 52, the ear 52 of the battery 50 can automatically align and extend into the cutting position inside the cutting assembly 30. The following will describe the specific structure of the adjusting assembly 40 in detail:

[0053] Furthermore, as Figure 1 shown, the adjusting assembly 40 includes a first driving member 41 and two clamping members 43; wherein, the fixed end of the first driving member 41 is slidably connected to the frame 10 along the Z-axis; two clamping members 43 are respectively connected to the two output ends of the first driving member 41, the two clamping members 43 are arranged opposite to each other along the Y-axis, and the center lines of the two clamping members 43 match the center line of the cutting position. The first driving member 41 is used to adjust the distance between the two clamping members 43, so that the two clamping members 43 can approach each other to clamp the battery body 51 of the battery 50, and at this time, the center line of the ear 52 can be made to coincide with the center line of the cutting position, thereby ensuring that the ear 52 is correctly aligned with the cutting position. Among them, the center lines of the two clamping members 43, the center line of the cutting position, the center line of the battery body 51, and the center line of the ear 52 coincide. In this embodiment, the first driving member 41 can specifically be a clamping jaw cylinder, and the two clamping members 43 are respectively connected to the two clamping jaws of the clamping jaw cylinder.

[0054] It should be noted that when adjusting the placement position and / or placement angle of the battery body 51, since the two clamping members 43 can only approach or move away from each other along the Y-axis, that is, the clamping members 43 will not move in the Z-axis and / or X-axis directions; at the same time, since the center lines of the two clamping members 43 match the center line of the cutting position, and the cutting position will not move in the Z-axis and / or Y-axis directions; therefore, only by clamping the battery body 51 with the two clamping members 43, it can be ensured that the center line of the ear 52 coincides with the center line of the cutting position, thereby ensuring that the ear 52 is correctly aligned with the cutting position.

[0055] Specifically, when the two clamping members 43 clamp the battery body 51, the inner side surfaces of the clamping members 43 are parallel and in abutting contact with the outer side surface of the battery body 51. That is, through the clamping action of the two clamping members 43, the placement position of the battery body 51 can be adjusted and the placement angle of the battery body 51 can be corrected and aligned, so that the battery body 51 and the ear 52 can be parallel to the X-axis, avoiding deflection of the placement position and / or placement angle of the battery 50 relative to the X-axis, and thus ensuring the adjustment and deviation correction effect of the adjustment assembly 40 on the battery 50.

[0056] Moreover, by slidably connecting the fixed end of the first driving member 41 to the frame 10 along the Z-axis, the first driving member 41 and the clamping member 43 as a whole can be moved along the Z-axis. When transferring the battery 50 to the conveying member 20 along the Y-axis in the previous process, it is necessary to move the first driving member 41 and the clamping member 43 upward along the Z-axis to disengage from the conveying member 20, so as to avoid interference of the clamping member 43 with the operation of transferring the battery 50 to the conveying member 20, and ensure that the battery 50 can be smoothly transferred from the previous process to the conveying member 20 along the Y-axis.

[0057] Specifically, as Figure 1 shown, the adjustment assembly 40 further includes a second driving member 42. The fixed end of the second driving member 42 is fixedly connected to the frame 10, and the output end of the second driving member 42 is connected to the fixed end of the first driving member 41. The second driving member 42 is used to drive the first driving member 41 and the clamping member 43 to move along the Z-axis, so that the first driving member 41 and the clamping member 43 can be moved upward along the Z-axis to disengage from the conveying member 20. In this embodiment, the second driving member 42 can specifically be a vertical cylinder, and the conveying member 20 can specifically be a conveyor belt.

[0058] Furthermore, as Figure 1 shown, the clamping member 43 includes a first plate 431, a second plate 432 and a third plate 433. The first plate 431 and the third plate 433 are parallel to the Z-axis, the second plate 432 extends along the X-axis, and both ends of the second plate 432 are respectively connected to one end of the first plate 431 and one end of the third plate 433, so that the whole clamping member 43 has a Z-shaped structure. And the other end of the first plate 431 is connected to the first driving member 41, and the other end of the third plate 433 is used to clamp the battery body 51, that is, the two relatively arranged third plates 433 can clamp the battery body 51. In this embodiment, the first plate 431, the second plate 432 and the third plate 433 are integrally formed structures.

[0059] By setting the clamping member 43 to the above-mentioned Z-shaped structure, compared with directly setting the clamping member 43 as a straight plate, the structural strength of the entire clamping member 43 can be increased, avoiding the problem that the clamping member 43 is prone to breakage during long-term use, and ensuring that the clamping member 43 has relatively high stability and reliability in clamping the battery body 51. In other embodiments, the clamping member 43 can also be set to other structures, which is not specifically limited here.

[0060] Specifically, the clamping member 43 has a certain elasticity to provide an elastic buffering effect during the process of the clamping member 43 clamping the battery body 51, avoiding the clamping member 43 from scratching the battery body 51, and thus being able to provide a protective effect for the battery body 51.

[0061] It should be noted that the above-mentioned clamping member 43 specifically clamps the battery body 51 of the battery 50. Compared with the clamping member 43 directly clamping the ear 52 of the battery 50 for position and / or angle adjustment; on the one hand, it can make it easier for the clamping member 43 to clamp the relatively large battery body 51, and the clamping operation is simple and convenient; and the clamping member 43 does not need to be made into a small structure, making the processing of the clamping member 43 relatively simple and convenient; on the other hand, it can avoid damaging the ear 52, that is, the adjustment of both the ear 52 and the cutting position can be achieved by clamping the battery body 51, and at the same time, the ear 52 will not be damaged.

[0062] Further, as Figure 1 shown, at least one adjusting component 40 is provided between two adjacent cutting components 30; in this embodiment, two adjusting components 40 are provided between two adjacent cutting components 30, that is, the two adjusting components 40 simultaneously adjust the battery body 51, making the adjustment effect on the ear 52 more accurate, which is beneficial to simultaneously cutting the positive ear and the negative ear at opposite ends of the battery body 51 and ensuring the cutting quality.

[0063] In other embodiments, one adjusting component 40 can also be provided between two adjacent cutting components 30 to be able to adjust the battery body 51 through one adjusting component 40, saving costs and reducing the occupied space, making the structure of the entire ear cutting device relatively simple and compact.

[0064] The following will describe the specific structure of the cutting component 30 in detail:

[0065] Specifically, as Figures 1 to 3As shown, the cutting component 30 includes a first carrier 31, a second carrier 32, a displacement carrier 33, and an abutting table 313. Among them, the first carrier 31 is slidably connected to the frame 10 along the X-axis, so that the entire cutting component 30 can be driven by the first carrier 31 to slide on the X-axis. The second carrier 32 is disposed at an interval above the first carrier 31. The displacement carrier 33 is slidably connected between the first carrier 31 and the second carrier 32 along the Z-axis. A cutter 331 extending along the Y-axis is provided on the displacement carrier 33. A first cutting edge is provided on the bottom end surface of the cutter 331 near the first edge of the abutting table 313. The abutting table 313 is connected to the first carrier 31 and is parallel and located on one side of the cutter 331, that is, the cutter 331 and the abutting table 313 are staggered. The tab 52 can extend onto the abutting table 313 and be located below the first cutting edge after passing through the cutting position. A second cutting edge 3131 is provided on the top end surface of the abutting table 313 near the second edge of the first edge, that is, the first cutting edge and the second cutting edge 3131 are adjacent and parallel to the Y-axis.

[0066] By respectively providing the first cutting edge and the second cutting edge 3131 on the cutter 331 and the abutting table 313, when the displacement carrier 33 drives the cutter 331 to move downward along the Z-axis while the abutting table 313 remains stationary, due to the mutual cooperation and cutting action between the first cutting edge and the second cutting edge 3131, the length of the tab 52 on the abutting table 313 can be cut by the first cutting edge and the second cutting edge 3131.

[0067] Further, as Figure 3 shown, the cutting component 30 further includes a guiding member 312. The guiding member 312 is fixedly connected to the first carrier 31 and is located on one side of the abutting table 313. A limiting slot 3121 is formed on the guiding member 312. The tab 52 can be snapped into the limiting slot 3121 and extend onto the abutting table 313, so as to facilitate the cutting of the tab 52 by the first cutting edge and the second cutting edge 3131. Among them, the limiting slot 3121 is the above-mentioned cutting position, that is, the center line of the tab 52 needs to coincide with the center line of the limiting slot 3121 to ensure that the tab 52 can be smoothly and accurately inserted into the cutting position for subsequent cutting of the tab 52.

[0068] By snapping the tab 52 into the limiting slot 3121, it can ensure that the tab 52 is accurately inserted into the cutting position. That is, when the tab 52 can be accurately inserted into the limiting slot 3121, it can ensure better cutting quality of the tab 52 and realize the limiting function of the tab 52.

[0069] Specifically, as Figure 3As shown, the cutting assembly 30 further includes a pressing member 332. The pressing member 332 is connected to the displacement stage 33 and is located on one side of the cutting blade 331. The pressing member 332 is located above the abutting table 313. The pressing member 332 is used to press the tab 52 tightly against the abutting table 313. That is, after the tab 52 is snap-fitted and limited in the limiting slot 3121, the tab 52 can be abutted between the abutting table 313 and the pressing member 332, which is beneficial to the cutting work of the tab 52 and can prevent one end of the tab 52 close to the battery body 51 from warping during cutting, thereby further ensuring the cutting quality of the tab 52. In this embodiment, the pressing member 332 may specifically be an elastic strip.

[0070] Further, as Figure 1 and Figure 2 shown, the cutting assembly 30 further includes a waste box 311. The waste box 311 is connected to the first stage 31 and is located below the cutting blade 331. The waste box 311 is used to collect the waste tabs 52 cut off, so as to uniformly collect and manage the waste tabs 52.

[0071] Specifically, as Figure 1 and Figure 2 shown, a plurality of spaced connecting columns 34 are connected between the first stage 31 and the second stage 32. The displacement stage 33 is sleeved on each connecting column 34, so that the displacement stage 33 is connected between the first stage 31 and the second stage 32; and, a third driving member 321 is installed on the second stage 32. The output shaft of the third driving member 321 passes through the second stage 32 and is connected to the displacement stage 33, so as to be able to drive the displacement stage 33 to move along the Z-axis on the connecting column 34 through the third driving member 321. In this embodiment, the third driving member 321 is specifically a linear cylinder.

[0072] Further, as Figure 2 shown, a connecting block 323 is connected to the output shaft of the third driving member 321 after passing through the second stage 32. The connecting block 323 is fixedly installed on the top end surface of the displacement stage 33, and an elastic member 322 is sleeved on the output shaft of the third driving member 321. The two ends of the elastic member 322 respectively abut against the bottom end surface of the second stage 32 and the top end surface of the connecting block 323. In this embodiment, the elastic member 322 may specifically be a tension spring.

[0073] Specifically, when the third driving member 321 operates, the output shaft of the third driving member 321 extends downward along the Z-axis to drive the connecting block 323 and the displacement stage 33 to move downward along the Z-axis. At this time, the elastic member 322 is stretched; when the output shaft of the third driving member 321 resets upward along the Z-axis, the output shaft of the third driving member 321 can drive the connecting block 323 and the displacement stage 33 to reset; at the same time, the connecting block 323 and the displacement stage 33 can also automatically reset under the elastic action of the elastic member 322, so as to ensure the automatic reset effect of the displacement stage 33.

[0074] Specifically, when the displacement stage 33 moves to an appropriate position, the displacement stage 33 can be restricted at this position by a limiting member (not shown in the figure) to provide mechanical limitation for the displacement stage 33 and prevent the displacement stage 33 from sliding along the connecting column 34 under accidental circumstances, ensuring the fixing stability and reliability of the displacement stage 33 at this position. Among them, the limiting member can specifically be a limiting nut provided on the connecting column 34. Here, the specific structure of the limiting member is not limited, as long as it can achieve the mechanical limiting effect on the displacement stage 33.

[0075] The specific working process of the tab cutting device in this embodiment is as follows:

[0076] First, use the conveying member 20 to convey the battery 50 along the Y-axis to the middle of two adjacent cutting assemblies 30; then, make the second driving member 42 drive the first driving member 41 and the clamping member 43 to move downward along the Z-axis, so that the clamping member 43 moves to one side of the battery body 51; after that, make the first driving member 41 adjust the distance between the two clamping members 43, so that the two clamping members 43 approach each other to clamp the battery body 51 of the battery 50. At this time, the center line of the battery body 51, the center line of the tab 52, the center lines of the two clamping members 43, and the center line of the limiting card slot 3121 coincide.

[0077] Then, make the first stage 31 slide on the frame 10 along the X-axis to drive the entire cutting assembly 30 to move in the direction of approaching the tab 52 along the X-axis, that is, at this time, the cutting assembly 30 is located on one side of the adjusting assembly 40; during the process of the cutting assembly 30 moving in the direction of approaching the tab 52 along the X-axis, the tab 52 can automatically align and insert into the limiting card slot 3121 along the X-axis, that is, the limiting card slot 3121 limits and clamps the tab 52 at the cutting position in the cutting assembly 30; at the same time, the tab 52 after being clamped into the limiting card slot 3121 moves to the abutting platform 313.

[0078] Finally, the third driving member 321 is further used to drive the displacement stage 33 to move downward along the Z-axis, so that the pressing member 332 on the displacement stage 33 presses the tab 52 tightly against the abutting table 313, and at the same time, the cutting tool 331 can be driven to move downward along the Z-axis, so that the first cutting edge on the cutting tool 331 and the second cutting edge 3131 that remains stationary on the abutting table 313 cooperate with each other to cut off the tab 52; and the waste tab 52 cut off automatically falls into the waste box 311 for recycling; thus completing the entire process of conveying, adjusting and rectifying the deviation, and cutting the tab 52.
