[0034] Reference Figures 1 to 6In certain embodiments of the first aspect of the present invention, a tab cutting device is provided for cutting the tabs 710 of a battery cell 700. The tab cutting device includes a base 100. In this embodiment, the base 100 includes a substantially rectangular parallelepiped base, the upper portion of which is provided with an upwardly extending upright portion. A jig 200 is detachably mounted on the top of the upright portion. One end of the jig 200 extends forward relative to the base 100. The jig 200 extends to the front side of the base 100. The upper surface of the end thereof, which is provided with a mounting position 210 that matches the shape of the battery cell 700 to be cut. The battery cell 700 to be cut can be placed in the mounting position 210 for positioning. A movable platform 300 is movably mounted on the base 100 and is capable of reciprocating relative to the base 100. In this embodiment, the movable platform 300 is movably mounted on the front side of the base 100 and is located below the jig 200. A cutter mechanism 400 for cutting the tabs 710 is fixedly mounted on the mobile platform 300. The mobile platform 300 can drive the cutter mechanism 400 to move relative to the base 100, toward or away from the jig 200. In this embodiment, the base 100 is equipped with an adjustment mechanism 500, which is in transmission connection with the mobile platform 300. During operation, the adjustment mechanism 500 can drive the mobile platform 300 to synchronously move the cutter mechanism 400 toward or away from the jig 200. A locking mechanism is also provided between the base 100 and the mobile platform 300. The locking mechanism can lock the movable platform 300 to the base 100, thereby keeping the relative position between the movable platform 300 and the base 100 unchanged, or the locking mechanism can release the lock between the movable platform 300 and the base 100. At this time, the adjustment mechanism 500 can drive the movable platform 300 to drive the cutter mechanism 400 to move synchronously to move closer to or away from the fixture 200, so that the user can adjust the distance between the cutter mechanism 400 and the fixture 200.

[0035] The tab cutting device of this embodiment uses an adjustment mechanism 500 to drive the mobile platform 300 to drive the cutter mechanism 400 to move closer to or away from the jig 200, thereby adjusting the distance between the cutter mechanism 400 and the battery cell 700 placed on the jig 200, and then locks the mobile platform 300 to the base 100 through the locking mechanism. At this time, the distance between the cutter mechanism 400 and the battery cell 700 is ensured to remain unchanged, so that the tab cutting device can cut tabs of different lengths according to actual needs, and the operation is more convenient and quick. It also abandons the traditional need to prepare a variety of jigs with different thickness specifications, thereby reducing the company's production costs.

[0036] It is understandable that, in addition to the above-mentioned structure consisting of a base and an upright portion, the base 100 may also adopt other structures. In other embodiments of the present invention, the base 100 may also be just a frame. The specific structure may be determined according to actual needs and is not limited here.

[0037] In addition, it should be noted that in the above embodiment, the movable platform 300 and the cutter mechanism 400 are disposed below the jig 200. When the battery cell 700 is mounted on the mounting position 210 of the jig 200, the adjustment mechanism 500 can drive the movable platform 300 and the cutter mechanism 400 to move vertically toward or away from the jig 200, thereby enabling the tab cutting device to adjust the distance between the cutter mechanism 400 and the tab 710 of the battery cell 700 vertically. In addition to the above structure, the tab cutting device may also adopt other structures. For example, in certain embodiments of the present invention, the jig 200 is fixedly mounted on the base 100, the movable platform 300 is movably mounted on the base 100, and the cutter mechanism 400 is mounted on the movable platform 300. In this embodiment, the movable platform 300 and the jig 200 are located at the same horizontal height, and the base 100 is provided with an adjustment mechanism 500 that drives the movable platform 300 to move horizontally toward or away from the jig 200. By adopting the above-mentioned structure, the adjustment mechanism 500 can drive the mobile platform 300 and the cutter mechanism 400 to move horizontally toward or away from the jig 200, thereby adjusting the distance between the cutter mechanism 400 and the tab 710 of the battery cell 700. Therefore, the cutter mechanism 400 can cut tabs 710 of different lengths. The above-mentioned embodiment only discloses that the mobile platform 300 moves in the vertical direction or horizontal direction to move toward or away from the jig 200. In other embodiments of the present invention, the mobile platform 300 can also move in other different directions to move toward or away from the jig 200, which is not limited here.

[0038] Reference Figure 3 and Figure 4 In order to make the process of the mobile platform 300 driving the cutter mechanism 400 to move closer to or away from the fixture 200 more stable, in certain embodiments of the present invention, the upright portion of the base 100 is further provided with a slide rail pair 110 arranged in the up-down direction. The mobile platform 300 is connected to the slide rail pair 110. At this time, the slide rail pair 110 can guide the mobile platform 300 to move up and down in the up-down direction to move closer to or away from the fixture 200. In this embodiment, the slide rails of the slide rail pair 110 are fixedly mounted on the upright portion of the base 100. The slide rails are arranged in the up-down direction. The mobile platform 300 is mounted on the slider of the slide rail pair 110. Therefore, when the slider slides up and down along the slide rail, the mobile platform 300 can move up and down along the slide rail following the slider, ensuring that the mobile platform 300 drives the cutter mechanism 400 to move up and down more smoothly and stably.

[0039] To facilitate adjustment of the distance between the cutter mechanism 400 and the fixture 200, in certain embodiments of the present invention, the adjustment mechanism 500 includes a micrometer fixedly mounted on the base 100, with the movable end of the micrometer being in transmission connection with the mobile platform 300. Specifically, a mounting base 101 is provided on the left side of the base 100, to which the micrometer is fixedly mounted, and positioned below the mobile platform 300. A connecting block 111 is provided on the slider, positioned directly above the micrometer, and the movable end of the micrometer is connected to the connecting block 111. By adjusting the micrometer, the user can drive the connecting block 111 to move the mobile platform 300 and the cutter mechanism 400 up and down. In this embodiment, a micrometer is used to drive the mobile platform 300 to drive the cutter mechanism 400 to move synchronously up and down toward or away from the jig 200, so that the user can more accurately adjust the distance between the cutter mechanism 400 and the jig 200, and then the cutter mechanism 400 can accurately cut the tab 710 of the battery cell 700 placed on the jig 200, ensuring that the cutting length of the tab 710 meets the production requirements of the enterprise.

[0040] It should be noted that, in certain embodiments of the present invention, the movable end of the micrometer may also be directly connected to the mobile platform 300 , which may be determined according to actual needs and is not limited here.

[0041] It is understood that the adjustment mechanism 500 may employ other structures besides the aforementioned micrometer. For example, the adjustment mechanism 500 may be a linear motor fixedly mounted on the base 100, with the output end of the linear motor being in transmission connection with the movable platform 300. When necessary, the linear motor drives the movable platform 300, which in turn moves the cutter mechanism 400 toward or away from the fixture 200. The adjustment mechanism 500 may employ other structures besides the aforementioned structure, which are not limited herein.

[0042] Reference Figure 1 and Figure 2In order to simplify the structure of the tab cutting device, in some embodiments of the present invention, the cutter mechanism 400 includes a first cutter assembly and a second cutter assembly, and the first cutter assembly and the second cutter assembly are correspondingly arranged on both sides of the installation position 210. The first cutter assembly includes a first driving mechanism 410 arranged on one side of the mobile platform 300, and the first driving mechanism 410 is transmission-connected to the first cutter 411, and the first driving mechanism 410 can drive the first cutter 411 to move closer to or away from the installation position 210; the second cutter assembly includes a second driving mechanism 420 arranged on the other side of the mobile platform 300, and the second driving mechanism 420 is transmission-connected to the second cutter 421, and the second driving mechanism 420 can drive the second cutter 421 to move closer to or away from the installation position 210. In this embodiment, the first drive mechanism 410 is a first piston cylinder mounted on one side of the mobile platform 300, and the second drive mechanism 420 is a second piston cylinder mounted on the other side of the mobile platform 300. The output end of the first piston cylinder is connected to the first tool mounting seat 430, and the output end of the second piston cylinder is connected to the second tool mounting seat 440. The first cutter 411 is detachably mounted on the first tool mounting seat 430, and the second cutter 421 is detachably mounted on the second tool mounting seat 440. By adopting this structure, when the cutter mechanism 40 cuts the tab 710, the first piston cylinder and the second piston cylinder can respectively drive the first and second cutter mounting seats 430 and 440 to move toward each other. In turn, the first and second cutter mounting seats 430 and 440 can respectively drive the first and second cutters 411 and 421 to move toward each other and cooperate in cutting the tab 710, resulting in a simpler structure. The first and second piston cylinders can be configured as pneumatic cylinders or hydraulic cylinders, depending on actual needs.

[0043] It should be noted that, in addition to the above-described structures, the first drive mechanism 410 and the second drive mechanism 420 may also employ other structures. In certain embodiments of the present invention, the first drive mechanism 410 and the second drive mechanism 420 may also be configured as linear motors fixedly mounted on the mobile platform 300, with the first cutter 411 mounted at the output end of one of the linear motors, and the second cutter 421 mounted at the output end of the other linear motor. The two linear motors cooperate to drive the first cutter 411 and the second cutter 421 to move toward each other and cooperate to cut the tab 710. The first drive mechanism 410 and the second drive mechanism 420 may also employ other structures, which are not limited herein.

[0044] Reference Figures 1 to 5In order to make the cutting mechanism 400 cut the tab 710 more effectively, in certain embodiments of the present invention, an open groove 211 is opened on a side wall of the mounting position 210 facing the second cutter assembly, and the second driving mechanism 420 is transmission-connected to a pressing member 422 located on one side of the open groove 211. The second driving mechanism 420 can drive the pressing member 422 to move closer to or away from the open groove 211. Specifically, the open groove 211 is opened on the side wall of the jig 200 facing the second cutter assembly. At this time, the side wall of the mounting position 210 facing the second cutter assembly has a notch. When the battery cell 700 is installed in the mounting position 210, part of the battery cell 700 can protrude from the above-mentioned open groove 211 to the outside of the mounting position 210. When the second driving mechanism 420 drives the second cutter 421 to move close to the mounting position 210, the second driving mechanism 420 can drive the clamping member 422 to move synchronously close to the mounting position 210. At this time, the clamping member 422 can cooperate with the jig 200 to clamp the battery cell 700 together, so as to prevent the battery cell 700 from shaking during the process of the cutter mechanism 400 cutting the pole ear 710, thereby ensuring the cutting quality of the cutter mechanism 400 in cutting the pole ear 710.

[0045] In order to prevent the cut tab waste from adhering to the first cutter 411 and / or the second cutter 421, in certain embodiments of the present invention, the second cutter 421 is mounted on a pressing member 422. A relief groove 424 is defined on the side of the pressing member 422 facing the first cutter 411. The blades of the second cutter 421 and the first cutter 411, which cooperate in cutting, are located within the relief groove 424. The sidewalls of the relief groove 424 are defined with air outlets 423 facing the second cutter 421 or with air outlets 423 adjacent to the second cutter 421. By adopting the above structure, when the second driving mechanism 420 drives the pressing member 422 and the second cutter 421 to move close to the installation position 210, the first driving mechanism 410 drives the first cutter 411 to move close to the installation position 210, the first cutter 411 extends out of the avoidance groove 424 and cooperates with the second cutter 421 to cut the tab 710. At this time, the wind blown out from the blowing port 423 can blow away the tab waste adhering to the first cutter 411 or the second cutter 421, so that the first cutter 411 or the second cutter 421 can cut the tab 710. In order to facilitate the introduction of high-pressure air into the blowing port 423, in this embodiment, an air nozzle 425 connected to the blowing port 423 is installed on the outer wall of the pressing member 422, and the air nozzle 425 can be connected to an external high-pressure air source.

[0046] Reference Figure 6In order to better collect the waste after the tab 710 is cut, in some embodiments of the present invention, the tab cutting device further includes a waste collection hopper 800. The waste collection hopper 800 is roughly in the shape of a funnel with a larger top and a smaller bottom. The waste collection hopper 800 is arranged below the jig 200, and openings are provided on both sides of the waste collection hopper 800 corresponding to the positions of the first cutter 411 and the second cutter 421. Therefore, it will not interfere with the first cutter 411 and the second cutter 421 moving toward each other to cooperate in cutting the tab 710. After the tab 710 is cut, the waste falls into the waste collection hopper 800 and is collected, which makes it convenient for enterprises to collect and clean up waste.

[0047] In certain embodiments of the present invention, the first cutter 411 is provided with two blades 412. Specifically, the two blades 412 are symmetrically arranged on the upper portion of the first cutter 411 about the axis of the first cutter 411, and the two blades 412 face opposite directions. By adopting this structure, when the blade 412 of the first cutter 411 facing the second cutter 421 wears out due to long-term use, the user can remove the first cutter 411 from the first cutter mounting base 430 and then reversely install the first cutter 411 on the first cutter mounting base 430, with the other unused blade 412 of the first cutter 411 facing the second cutter 421. The first cutter 411 can then cooperate with the second cutter 421 to cut the tab 710. In this embodiment, the first cutter 411 and the second cutter 421 are both ceramic cutters. It is understood that the first cutter 411 and the second cutter 421 can also be configured as metal cutters. The specific configuration can be determined based on actual needs and is not limited here.

[0048] In order to make the structure of the locking mechanism more compact, in certain embodiments of the present invention, referring to Figure 4 The locking mechanism includes a connecting plate 610 and a locking bolt 620. The connecting plate 610 has a strip-shaped hole 611, and the locking bolt 620 is inserted into the strip-shaped hole 611. When the connecting plate 610 is fixedly mounted on the base 100, the locking bolt 620 is threadedly mounted on the mobile platform 300. Alternatively, when the connecting plate 610 is fixedly mounted on the mobile platform 300, the locking bolt 620 is threadedly mounted on the base 100. The locking bolt 620 cooperates with the connecting plate 610 to lock the mobile platform 300 to the base 100, or the locking bolt 620 cooperates with the connecting plate 610 to release the lock between the mobile platform 300 and the base 100.

[0049] In this embodiment, the connecting plate 610 is fixedly installed on the base 100, and the locking bolt 620 is threadedly installed on the mobile platform 300. When the user loosens the locking bolt 620, the locking bolt 620 does not press the connecting plate 610. At this time, the mobile platform 300 can drive the locking bolt 620 to move relative to the base 100, and the locking bolt 620 moves along the strip hole 611. When the user turns the locking bolt 620 to press the connecting plate 610, the locking bolt 620 and the connecting plate 610 cooperate to connect the mobile platform 300 and the base 100 to form a whole. At this time, the mobile platform 300 cannot move relative to the base 100, thereby realizing the function of the locking mechanism to lock the mobile platform 300 to the base 100.

[0050] It should be noted that, in addition to the above-mentioned structure composed of the connecting plate 610 and the locking bolt 620, the locking mechanism may also adopt other structures. For example, the locking mechanism may include an electromagnet fixedly mounted on the base 100, and the mobile platform 300 may be provided with a metal strip that cooperates with the electromagnet for adsorption. When the locking mechanism needs to lock the mobile platform 300 to the base 100, the electromagnet may be energized and generate a magnetic attraction force. At this time, the electromagnet adsorbs the metal strip on the mobile platform 300, thereby locking the mobile platform 300 to the base 100. If the lock between the mobile platform 300 and the base 100 needs to be released, it is only necessary to disconnect the power supply to the electromagnet. At this time, the mobile platform 300 can move relative to the base 100. In addition to the above-mentioned structure, the locking mechanism may also adopt other structures, which are not limited here.

[0051] Reference Figures 1 to 6 In certain embodiments of the present invention, a battery tab cutting automation device is provided, wherein the device body is provided with the above-mentioned tab cutting device.

[0052] The battery tab cutting automation equipment of this embodiment adopts the above-mentioned tab cutting device. When it is necessary to cut tabs of different lengths, the adjustment mechanism 500 can drive the mobile platform 300 to drive the cutter mechanism 400 to move closer to or away from the jig 200, thereby adjusting the distance between the cutter mechanism 400 and the battery cell 700 placed on the jig 200. Then the locking mechanism locks the mobile platform 300 to the base 100. Therefore, the battery tab cutting automation equipment can cut battery cells 700 with tabs of different lengths according to actual needs, making the operation more convenient and quick, and also reducing the production cost of the enterprise.
