Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, specifically to a cutting device. Background Technology

[0002] The cutting devices in related technologies typically use flatbed cutting machines for manual cutting. This requires the battery cells to be loaded into the carrier module twice and cut twice to complete the entire operation process, which involves four steps and is labor-intensive. Utility Model Content

[0003] In view of this, the present invention provides a cutting device to solve the problem of manual cutting and high labor costs.

[0004] This utility model provides a cutting device, comprising: a base module; a carrier module detachably disposed on the base module for carrying a battery cell; a first positioning member disposed on the base module; a second positioning member disposed on the base module and movable between a clamping position and a separating position, wherein when the second positioning member is in the clamping position, the second positioning member and the first positioning member clamp the carrier module; and when the second positioning member is in the separating position, the second positioning member separates from the carrier module; a driving module disposed on the base module; and a cutting module connected to the driving module, wherein the driving module drives the cutting module to cut the tabs of the battery cell.

[0005] Beneficial effects: By setting a drive module to move the cutting module vertically, the cutting efficiency of the battery cell tabs can be improved, reducing manual operation steps, increasing production efficiency, and reducing labor costs. Furthermore, by setting a first positioning member and a second positioning member, with the second positioning member movable between a clamping position and a separating position, the battery cell's position can be fixed, and the battery cell can be separated from the cutting device. This not only improves the positioning efficiency of the battery cell and the cutting device but also eliminates the need for manual operation, reducing manual operation steps, increasing production efficiency, and reducing labor costs. In addition, by setting a carrier module, the first and second positioning members clamp the carrier module, preventing direct external force on the battery cell. This not only secures the battery cell to the cutting device but also reduces the probability of battery cell damage due to force, ensuring a high yield rate.

[0006] In one optional embodiment, the cutting device further includes a detection module, wherein the base module is provided with a receiving groove, the detection module is disposed in the receiving groove, the carrier module is located above the detection module and covers the receiving groove, and the detection module is used to detect the position of the carrier module.

[0007] Beneficial effects: By setting up a detection module, it is possible to detect whether the carrier module is placed on the base module, thereby realizing material detection, which can improve the automation level of the cutting device and achieve the effect of reducing manpower and increasing production capacity.

[0008] In one optional embodiment, the first positioning member is provided with a first through hole, and the base module is provided with a second through hole. The extension direction of the first through hole and the extension direction of the second through hole are at a preset angle. The cutting device further includes a fixing member, which passes through the first through hole and the second through hole. The fixing member is movable relative to the first through hole along the extension direction of the first through hole and is movable relative to the second through hole along the extension direction of the second through hole.

[0009] Beneficial effects: By setting a fixing member that can move along the extension direction of the first through hole, the relative positions of the first positioning member and the base module in the extension direction of the first through hole can be adjusted. By setting a fixing member that can move along the extension direction of the second through hole, the relative positions of the first positioning member and the base module in the extension direction of the second through hole can be adjusted. Therefore, the relative positions of the first positioning member and the base module can be adjusted in at least two directions, which can adjust the position of the carrier module in a timely manner, ensure the cutting effect of the electrode tab of the battery cell, and adapt to carrier modules of different sizes, thereby adapting to battery cells of different sizes and improving the applicability of the cutting device.

[0010] In one optional embodiment, the cutting module includes: an upper cutting blade connected to the drive module; and a lower cutting blade connected to the base module and located below the carrier module, wherein the lower cutting blade and the upper cutting blade are offset in the horizontal direction.

[0011] Beneficial effects: By setting up upper and lower cutters, the tabs can be cut from opposite sides in the vertical direction, improving cutting efficiency and accuracy. Furthermore, since the lower cutter is fixed to the base module, the upper cutter moves vertically relative to the base module, which reduces the energy required to drive the cutter module and lowers energy consumption.

[0012] In one optional embodiment, the upper cutter has a first arc-shaped surface, and the lower cutter has a second arc-shaped surface. When the upper cutter and the lower cutter are located on the same horizontal plane, the first arc-shaped surface and the second arc-shaped surface are opposite to each other. One of the first arc-shaped surface and the second arc-shaped surface is convex and the other is concave. The central axis of the first arc-shaped surface and the central axis of the second arc-shaped surface coincide.

[0013] Beneficial effect: The cut surface of the tab is arc-shaped after cutting, which can avoid the tab having sharp corners after cutting and reduce the risk of the tab puncturing the battery pack.

[0014] In one optional embodiment, the cutter module further includes: a guide block, the guide block being disposed on the drive module and located below the upper cutter, the guide block having a first guide surface on the side facing the lower cutter, the first guide surface extending beyond the side of the upper cutter facing the lower cutter, the first arc-shaped surface being recessed, and the first guide surface and the second guide surface being fitted together; wherein, in the horizontal direction, the side of the upper cutter facing the lower cutter is spaced apart from the second guide surface.

[0015] Beneficial effects: Since the first guide surface of the guide block and the second guide surface of the lower cutter are in contact, when the upper cutter is driven to move vertically by the drive module, the first guide surface and the second guide surface can act as guide surfaces to avoid collision between the upper cutter and the lower cutter, and ensure the relative position between the upper cutter and the lower cutter is stable, resulting in high cutting accuracy of the tabs and improved yield.

[0016] In one optional embodiment, the carrier module includes: a carrier plate disposed on the base module and having a mounting groove, the mounting groove having two tab notches on its wall, the mounting groove being used to mount the battery cell, the two tabs of the battery cell being correspondingly disposed in the two tab notches; and a pressure plate mounted on the upper surface of the carrier plate, a portion of the pressure plate being located above the mounting groove.

[0017] Beneficial effects: By setting up a carrier plate and a pressure plate, the battery cell can be fixed in the mounting slot, preventing the battery cell from coming out of the mounting slot. Even if the carrier module is moved, there will be no relative position between the battery cell and the carrier module, ensuring the stability of the relative position between the battery cell and the carrier module. Furthermore, when the pressure plate and the carrier plate are separated, the mounting slot is opened, allowing the battery cell to be replaced, resulting in high production efficiency.

[0018] In one alternative embodiment, the carrier plate includes: a support portion having the mounting groove, and the pressure plate being mounted on the support portion; and a handle portion connected to the end of the support portion away from the cutter module, the width of the handle portion being greater than the width of the support portion, and the upper surface of the handle portion having a handle groove.

[0019] Beneficial effects: When the operator holds the handle, their fingers can be placed in the groove, which limits the position of the fingers and increases the reliability of the grip. Furthermore, the volume of the support unit can be smaller, and it avoids the cutter module, reducing the probability of collision with the cutter module, and also reducing costs and weight.

[0020] In one optional embodiment, the drive module includes: a mounting plate disposed on the base module; a first drive member disposed on the mounting plate; a slide rail disposed on the side of the mounting plate facing the carrier module and extending vertically; a slider slidably disposed on the slide rail and connected to the first drive member, the cutter module being disposed on the side of the slider facing the carrier module; and a limiting post disposed on the mounting plate and located below the slider, for limiting the extreme position of the slider's downward sliding.

[0021] Beneficial effects: By setting the mounting plate, the relative positions of the first drive component, the slide rail, and the base module can be fixed. By setting the sliding component, the driving force of the first drive component can be transmitted to the upper cutter, enabling the upper cutter to move vertically and thus cut the tabs of the battery cell. By setting the limiting post, the sliding stroke of the sliding component can be limited, preventing the sliding component from sliding too far downward and disengaging from the slide rail, ensuring the continuous effectiveness of the sliding component, and thus ensuring high reliability of the cutting device.

[0022] In one optional embodiment, the base module includes: a mounting base plate, the drive module being disposed on the mounting base plate; a cutting base plate, the cutting base plate being disposed on the mounting base plate and having a positioning opening, the first positioning member and the carrier module being disposed on the cutting base plate; and a second drive member, the second drive member being disposed on the mounting base plate and located within the positioning opening, the second positioning member being connected to the second drive member.

[0023] Beneficial effects: It can not only ensure reliable positioning between the cutting base plate, the second driving component and the second positioning component, but also reduce the volume of the cutting base plate, and reduce cost and weight. Attached Figure Description

[0042] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0043] In related technologies, in order to improve the cutting efficiency of battery cell tabs, some cutting devices are equipped with a drive structure to drive the cutting blade assembly to move, thereby improving the automation level of the cutting device. However, the feeding of the above-mentioned cutting devices is generally still done by the operator to place and position the material, or by conveying it through a conveyor belt. The lack of a positioning structure leads to the impact on the cutting accuracy of the battery cell tabs.

[0044] The following is combined Figures 1 to 5 The following describes embodiments of the present invention.

[0045] According to an embodiment of the present invention, a cutting device 1 is provided, which includes a base module 100, a carrier module 200, a first positioning member 300, a second positioning member 400, a drive module 500, and a cutter module 600.

[0046] The carrier module 200 is detachably mounted on the base module 100. The carrier module 200 is used to carry the battery cell 2. The first positioning member 300 is mounted on the base module 100. The second positioning member 400 is mounted on the base module 100 and is movable between the clamping position and the separating position. When the second positioning member 400 is in the clamping position, the second positioning member 400 and the first positioning member 300 clamp the carrier module 200. When the second positioning member 400 is in the separating position, the second positioning member 400 is separated from the carrier module 200. The drive module 500 is mounted on the base module 100. The cutter module 600 is connected to the drive module 500. The drive module 500 drives the cutter module 600 to cut the tabs 3 of the battery cell 2.

[0047] For example, the first positioning member 300, the second positioning member 400, and the carrier module 200 can be located on the same side of the base module 100. The first positioning member 300 and the second positioning member 400 are in contact with at least two opposite sides of the carrier module 200 to apply a clamping force to the carrier module 200 in the same direction, preventing the carrier module 200 from rotating. Furthermore, the drive module 500 can be driven by a motor, hydraulic structure, cylinder, or other similar structure. The carrier module 200 and the cutter module 600 can be made of insulating material to avoid affecting the circuit performance of the battery cell 2, and the cutter module 600 can be made of ceramic material to improve cutting efficiency.

[0048] By setting the drive module 500 to drive the cutter module 600 to move vertically, the cutting efficiency of the tabs 3 of the battery cell 2 can be improved, the number of manual operation steps can be reduced, the production efficiency can be improved, the labor cost can be reduced, and the consistency of the cutting effect can be guaranteed.

[0049] In addition, by setting a first positioning member 300 and a second positioning member 400, and the second positioning member 400 being movable between the clamping position and the separation position, the position of the battery cell 2 can be fixed, and the battery cell 2 and the cutting device 1 can be separated. This not only facilitates the improvement of the positioning efficiency of the battery cell 2 and the cutting device 1, but also eliminates the need for manual operation, reduces the number of manual operation steps, improves production efficiency, reduces labor costs, and helps ensure the consistency of the cutting effect.

[0050] Furthermore, by setting up the carrier module 200, the first positioning member 300 and the second positioning member 400 clamp the carrier module 200, and no external force is directly applied to the battery cell 2. This not only achieves the fixation between the battery cell 2 and the cutting device 1, but also reduces the probability of the battery cell 2 being damaged by force, thus ensuring the yield rate.

[0051] like Figure 2 As shown, in the technical solution of this embodiment, the cutting device 1 further includes a detection module 700, a receiving groove 101 is provided on the base module 100, the detection module 700 is disposed in the receiving groove 101, and the carrier module 200 is located above the detection module 700 and covers the receiving groove 101.

[0052] For example, the detection module 700 can be a proximity sensor. In this case, the side of the carrier module 200 facing the detection module 700 can be made of metal. When the distance between the carrier module 200 and the detection module 700 changes, the induced current of the detection module 700 changes, thus determining whether the carrier module 200 is mounted on the base module 100. Alternatively, the detection module 700 can be a photoelectric sensor. When the distance between the carrier module 200 and the detection module 700 changes, the light received by the detection module 700 changes, leading to a change in the current of the detection module 700, thus determining whether the carrier module 200 is mounted on the base module 100. Furthermore, the detection module 700 can be a microswitch. When the carrier module 200 is mounted on the base module 100, it contacts the microswitch, and the microswitch can provide feedback electrical signals. Of course, it is understandable that the detection module 700 can also be other devices capable of detecting whether the carrier module 200 is mounted on the base module 100. The detection module 700 can perform detection through contact or non-contact methods.

[0053] Furthermore, the detection module 700 can be electrically connected to the drive module 500 via wire 710, or the detection module 700 can be connected to the controller via wire 710. The controller is connected to the drive module 500, and the drive module 500 can move vertically upon receiving an electrical signal from the detection module 700. The base module 100 may have a wire groove, and the wire 710 is disposed within the wire groove.

[0054] By setting up the detection module 700, it is possible to detect whether the carrier module 200 is placed on the base module 100, thereby achieving material presence detection. This improves the automation level of the cutting device 1, reducing manpower and increasing production capacity. Furthermore, the carrier module 200 is covered by the receiving groove 101, which avoids external structural interference with the detection module 700 and ensures the accuracy of the detection module 700.

[0055] like Figure 1As shown, in the technical solution of this embodiment, the first positioning member 300 is provided with a first through hole 301, and the base module 100 is provided with a second through hole 102. The extending direction of the first through hole 301 and the extending direction of the second through hole 102 are at a preset angle, for example, the extending direction of the first through hole 301 and the extending direction of the second through hole 102 can be 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, 90°, 100°, 110°, 120°, 130°, 140°, 150° or 160°. The cutting device 1 also includes a fixing member, which is movably disposed in the first through hole 301 and the second through hole 102. That is, the fixing member can move in the first through hole 301 along the extending direction of the first through hole 301, and the fixing member can move in the second through hole 102 along the extending direction of the second through hole 102.

[0056] For example, there can be multiple first through holes 301, multiple second through holes 102, and multiple fasteners. Multiple first through holes 301, multiple second through holes 102, and multiple fasteners are arranged in a one-to-one correspondence to achieve multi-point connection between the first positioning member 300 and the base module 100, improve the connection strength between the first positioning member 300 and the base module 100, and make the relative position between the first positioning member 300 and the base module 100 more stable.

[0057] Furthermore, the extension direction of each first through hole 301 and the extension direction of the wire groove can be the same, and multiple first through holes 301 are spaced apart along the extension direction of the second through hole 102, and multiple second through holes 102 are spaced apart along the extension direction of the second through hole 102.

[0058] By setting a fixing member that can move along the extension direction of the first through hole 301, the relative positions of the first positioning member 300 and the base module 100 in the extension direction of the first through hole 301 can be adjusted. By setting a fixing member that can move along the extension direction of the second through hole 102, the relative positions of the first positioning member 300 and the base module 100 in the extension direction of the second through hole 102 can be adjusted. Therefore, the relative positions of the first positioning member 300 and the base module 100 can be adjusted in at least two directions, which can adjust the position of the carrier module 200 in a timely manner, ensure the cutting effect of the tab 3 of the battery cell 2, and adapt to carrier modules 200 of different sizes, thereby adapting to battery cells 2 of different sizes and improving the applicability of the cutting device 1.

[0059] like Figure 4As shown, in the technical solution of this embodiment, the carrier module 200 includes a carrier plate 210 and a pressure plate 220. The carrier plate 210 is disposed on the base module 100 and is provided with a mounting groove 211. The groove wall of the mounting groove 211 is provided with two tab notches 212. The mounting groove 211 is used to install the battery cell 2. The two tabs 3 of the battery cell 2 are correspondingly disposed in the two tab notches 212. The pressure plate 220 is installed on the upper surface of the carrier plate 210, and a part of the pressure plate 220 is located above the mounting groove 211.

[0060] Install the battery cell 2 into the mounting groove 211 of the carrier plate 210, and place the two tabs 3 (i.e., positive tab 3 and negative tab 3) of the battery cell 2 in the two tab notches 212 one by one. The openings of the two tabs 3 are spaced apart along the axial direction of the mounting groove 211. The mounting groove 211 can be a circular groove, the battery cell 2 can be a button battery, and the included angle of the two tabs 3 can be 90°.

[0061] By setting the carrier plate 210 and the pressure plate 220, the battery cell 2 can be fixed in the mounting slot 211, preventing the battery cell 2 from coming out of the mounting slot 211. Even if the carrier module 200 is moved, there will be no relative position between the battery cell 2 and the carrier module 200, ensuring that the relative position between the battery cell 2 and the carrier module 200 is stable. Furthermore, when the pressure plate 220 and the carrier plate 210 are separated, the mounting slot 211 is opened, allowing the battery cell 2 to be replaced, resulting in high production efficiency.

[0062] Specifically, the carrier plate 210 includes a support portion 213 and a handle portion 214. A mounting groove 211 is located at one end of the support portion 213 near the cutter module 600. The handle portion 214 is connected to the end of the support portion 213 away from the cutter module 600. The support portion 213 is located between the handle portion 214 and the cutter module 600. The width of the support portion 213 is smaller than the width of the handle portion 214. The support portion 213 is connected to the center of the handle portion 214 in its width direction. A pressure plate 220 is connected to the support portion 213, and the width of the pressure plate 220 can be the same as the width of the support portion 213. A handle groove 215 is provided on the upper surface of the handle portion 214.

[0063] The handheld part 214 corresponds to the position of the detection module 700, that is, the side of the handheld part 214 facing away from the detection module 700 can be provided with a handheld groove 215.

[0064] In this way, when the operator holds the handle 214, the operator's fingers can be placed in the groove to limit the position of the operator's fingers and increase the reliability of the grip. In addition, the volume of the support part 213 can be smaller, and it avoids the cutter module 600, reducing the probability of collision with the cutter module 600, and can also reduce costs and weight.

[0065] like Figure 2As shown, in the technical solution of this embodiment, the first positioning member 300 includes a first side plate 310 and a second side plate 320, which are vertically arranged. The second positioning member 400 is provided with a positioning groove 410, which has a first groove wall 411 and a second groove wall 412. The first side plate 310 and the first groove wall 411 abut against opposite sides in the width direction of the handle portion 214, and the second side plate 320 and the second groove wall 412 abut against opposite sides in the length direction of the handle portion 214.

[0066] In this way, the first positioning member 300 and the second positioning member 400 can clamp the carrier module 200 from two mutually perpendicular directions, resulting in better positioning of the carrier module 200 and improving the cutting accuracy of the tabs 3 of the battery cell 2.

[0067] like Figure 2 and Figure 3 As shown, in this embodiment, the cutting module 600 includes an upper cutting blade 610 and a lower cutting blade 620. The upper cutting blade 610 is connected to the drive module 500, and the lower cutting blade 620 is connected to the base module 100 and located below the carrier module 200. The lower cutting blade 620 and the upper cutting blade 610 are horizontally offset. The upper cutting blade 610 and the lower cutting blade 620 can be made of ceramic material.

[0068] By setting the upper cutter 610 and the lower cutter 620, the tabs 3 can be cut from opposite sides in the vertical direction, improving cutting efficiency and cutting accuracy. Furthermore, since the lower cutter 620 is fixed to the base module 100, the upper cutter 610 moves in the vertical direction relative to the base module 100, which reduces the energy required to drive the cutter module 600 to move and reduces energy consumption.

[0069] like Figure 2 and Figure 3 As shown, in the technical solution of this embodiment, the upper cutter 610 is provided with a first arc-shaped surface 611, and the lower cutter 620 is provided with a second arc-shaped surface 621. When the upper cutter 610 and the lower cutter 620 are located on the same horizontal plane, the first arc-shaped surface 611 and the second arc-shaped surface 621 are arranged opposite to each other. One of the first arc-shaped surface 611 and the second arc-shaped surface 621 is convex and the other is concave. The central axis of the first arc-shaped surface 611 and the central axis of the second arc-shaped surface 621 are coincident.

[0070] In this way, the cut surface of tab 3 is curved after cutting, which can avoid the tab 3 having sharp corners after cutting and reduce the risk of tab 3 puncturing the battery pack.

[0071] like Figure 2 and Figure 3As shown, in the technical solution of this embodiment, the cutter module 600 further includes a guide block 630. The guide block 630 is disposed in the drive module 500 and located below the upper cutter 610. There can be two guide blocks 630, which are located on opposite sides of the first arc-shaped surface 611. The side of the guide block 630 facing the lower cutter 620 is provided with a first guide surface 631. The first arc-shaped surface 611 is recessed and extends beyond the side of the upper cutter 610 facing the lower cutter 620. The side of the lower cutter 620 facing the guide block 630 is provided with a second guide surface 622. That is, in the horizontal direction, the side of the upper cutter facing the lower cutter and the second guide surface are spaced apart.

[0072] There can be two second guide surfaces 622, which are located on opposite sides of the second arc-shaped surface 621. The first guide surface 631 and the second guide surface 622 are fitted together, and the two first guide surfaces 631 and the two second guide surfaces 622 are fitted together in a one-to-one correspondence.

[0073] In this way, since the first guide surface 631 of the guide block 630 and the second guide surface 622 of the lower cutter 620 are in contact, when the drive module 500 drives the upper cutter 610 to move vertically, the first guide surface 631 and the second guide surface 622 can act as guide surfaces to avoid collision between the upper cutter 610 and the lower cutter 620, and ensure the relative position between the upper cutter 610 and the lower cutter 620 is stable, resulting in high cutting accuracy of the tab 3 and improved yield.

[0074] like Figure 2 and Figure 3 As shown, in the technical solution of this embodiment, the drive module 500 includes a mounting plate 510, a first drive component 520, a slide rail 530, a sliding component 540, and a limiting post 550.

[0075] Mounting plate 510 is disposed on base module 100, first drive member 520 is disposed on mounting plate 510, slide rail 530 is disposed on the side of mounting plate 510 facing carrier module 200 and extends vertically, sliding member 540 is slidably disposed on slide rail 530 and connected to first drive member 520, cutter module 600 is disposed on the side of sliding member 540 facing carrier module 200, and limiting post 550 is disposed on mounting plate 510 and located below sliding member 540, used to limit the extreme position of sliding member 540 downward.

[0076] For example, the mounting plate 510 can be constructed in an "L" shape. The mounting plate 510 may include a horizontal mounting section 511 and a vertical mounting section 512. The horizontal mounting section 511 is connected to the base module 100, and the vertical mounting section 512 is connected to the horizontal mounting section 511 and is located on the side of the horizontal mounting section 511 closer to the carrier module 200.

[0077] The first driving component 520 can be a device with driving function such as a motor or a cylinder. The first driving component 520 is installed on the side of the vertical mounting section 512 facing away from the carrier module 200, and the slide rail 530 is installed on the side of the vertical mounting section 512 facing the carrier module 200.

[0078] The sliding member 540 may include a lifting plate 541, a slider 542, and a sliding plate 543. The lifting plate 541 is connected to the sliding member 540 and is located above the mounting plate 510. The sliding plate 543 is connected to the lifting plate 541 and is located on the side of the slide rail 530 facing the carrier module 200. The slider 542 is slidably disposed on the slide rail 530 and is connected to the sliding plate 543. The first driving member 520 drives the lifting plate 541 to move vertically. The lifting plate 541 drives the sliding plate 543 to move vertically. The sliding plate 543 drives the slider 542 to slide along the slide rail 530.

[0079] The upper cutter 610 is installed on the side of the sliding plate 543 facing the carrier module 200. The limiting post 550 is located below the slide rail 530. When the slider 542 slides down to the limit position, it stops against the limiting post 550. The upper surface of the limiting post 550 is flat to increase the contact area between the slider 542 and the limiting post 550, and to ensure the limiting effect of the limiting post 550 on the slider 542.

[0080] The mounting plate 510 fixes the relative positions of the first drive component 520, the slide rail 530, and the base module 100. The sliding component 540 transmits the driving force of the first drive component 520 to the upper cutter 610, allowing the upper cutter 610 to move vertically and cut the tabs 3 of the battery cell 2. The limiting post 550 limits the sliding stroke of the sliding component 540, preventing it from sliding too far downward and disengaging from the slide rail 530, ensuring the continuous effectiveness of the sliding component 540, and thus ensuring the high reliability of the cutting device 1.

[0081] like Figure 1 , Figure 2 and Figure 5As shown, in this embodiment, the base module 100 includes a mounting base plate 110, a cutting base plate 120, and a second driving member 130. The driving module 500 is disposed on the mounting base plate 110. The cutting base plate 120 is disposed on the mounting base plate 110 and has a positioning opening 121. The first positioning member 300 and the carrier module 200 are disposed on the cutting base plate 120. The second driving member 130 is disposed on the mounting base plate 110 and located within the positioning opening 121. The second positioning member 400 is connected to the second driving member 130. The second driving member 130 can be a structure with a driving function, such as a motor or a cylinder, and is used to drive the second positioning member 400 to move between a separated position and a clamping position.

[0082] For example, the mounting base plate 110 is provided with a clearance hole 111. The sliding plate 543, the upper cutter 610 and the guide block 630 are positioned corresponding to the clearance hole 111. When the slider 542 stops against the limiting post 550, the sliding plate 543, the upper cutter 610 and the guide block 630 extend into the clearance hole 111. In this way, while ensuring the movement stroke of the upper cutter 610 and the guide block 630, the size of the sliding member 540 is reduced, which helps to reduce costs and weight.

[0083] Furthermore, the cross-sectional area of ​​the cutting base plate 120 is smaller than that of the mounting base plate 110. The second positioning member 400 includes a vertical section and a horizontal section. The lower end of the vertical section is connected to the second driving member 130, and the horizontal section is connected to the upper end of the vertical section. The horizontal section is located above the cutting bottom and is used to contact the carrier module 200. This not only ensures reliable positioning between the cutting base plate 120, the second driving member 130, and the second positioning member 400, but also reduces the volume of the cutting base plate 120, thereby lowering cost and weight.

[0084] In addition, a limiting groove 122 is provided on the side of the cutting base plate 120 near the drive module 500. The lower cutter 620 is installed in the limiting groove 122. The upper surface of the lower cutter 620 is flush with the upper surface of the cutting base plate 120. The lower cutter 620 can support the carrier module 200, which can realize the positioning between the lower cutter 620 and the cutting base plate 120 without causing interference between the lower cutter 620 and the carrier module 200, thus ensuring the installation reliability of the carrier module 200.

[0085] Furthermore, the cutting base plate 120 is provided with a notch 123 on the side near the drive module 500. The sliding plate 543, the upper cutter 610, and the guide block 630 are positioned corresponding to the notch 123. When the slider 542 stops against the limiting post 550, the sliding plate 543, the upper cutter 610, and the guide block 630 extend into the notch 123. In this way, while ensuring the movement stroke of the upper cutter 610 and the guide block 630, the size of the sliding member 540 is reduced, which helps to reduce costs and weight.

[0086] The following example illustrates the working process of cutting device 1:

[0087] First, the battery cell 2 is installed into the carrier module 200, and the carrier module 200 is placed on the cutting base plate 120. The carrier module 200 is located between the first positioning member 300 and the second positioning member 400.

[0088] Then, the detection module 700 detects the carrier module 200 and sends a material signal to the second drive member 130. The second drive member 130 drives the second positioning member 400 to move to the clamping position, and the second positioning member 400 and the first positioning member 300 clamp the carrier module 200.

[0089] Next, after the second driving component 130 is in position, it sends a signal to the first driving component 520. The first driving component 520 drives the lifting plate 541 to move down, the lifting plate 541 drives the sliding plate 543 to move down, the sliding plate 543 drives the slider 542 to slide down along the slide rail 530, and at the same time the upper cutter 610 moves down.

[0090] Then, the upper cutting blade 610 and the lower cutting blade 620 cut the tabs 3 alternately, and the two tabs 3 of the battery cell 2 are cut off in one go;

[0091] Next, the first driving component 520 rises, driving the lifting plate 541 to rise. The lifting plate 541 drives the sliding plate 543 to rise. The sliding plate 543 drives the slider 542 to slide upward along the slide rail 530. At the same time, the upper cutter 610 rises.

[0092] Finally, the second driving component 130 drives the second positioning component 400 to move to the separation position, separating the carrier module 200 from the base module 100, and taking out the battery cell 2 from the carrier module 200, thus completing the entire cutting process.

[0093] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
