[0049] The present application provides a battery module cutting device, which can at least be used to cut the battery module of an electric vehicle, and the device includes: a coiling device and a cutting device.

[0053] The present application provides a battery module cutting device including a coiling device and a cutting device, thereby realizing the use of one device to complete the two separation processes of winding the insulating plate and cutting the battery module. The battery module can first be wound by the coiling device to peel off the insulating plate attached to the bottom and the vertical surface, and then the battery module with the insulating plate removed is transferred to the cutting device for cutting, wherein the cutting component on the cutting device can be driven by the motion component to move to any position along the X-axis, Y-axis and Z-axis directions, thereby realizing precise cutting.

[0054] For ease of understanding, refer to Figures 1 to 10 , the specific structure and working principle of the battery module cutting equipment provided by the present application are explained in detail in combination with an embodiment.

[0055] refer to Figures 1 to 3 The present application provides a battery module cutting device, comprising: a coiling device 1 and a cutting device 2. Figure 2 As shown, the winding device 1 includes a first workbench 11 and a winding assembly 10 arranged on the first workbench 11. The first workbench 11 is constructed to carry a battery module, and the winding assembly 10 is constructed to wind the insulating sheet of the battery module located on the first workbench 11 during movement relative to the first workbench 11.

[0056] In one embodiment of the present application, reference Figure 4 and Figure 5 The coiling device 1 includes a first guide portion 12 and a sliding bracket 13. The first guide portion 12 is configured to be arranged on the first workbench 11 and is configured to extend along the X-axis direction. The sliding bracket 13 is configured to be slidably connected to the first guide portion 12. The coiling assembly 10 is configured to be arranged on the sliding bracket 13 and is configured to move along the X-axis direction under the driving action of the sliding bracket 13. Specifically, the X-axis direction can be the extension direction of the long side of the battery module. The first guide portion 12 can be a slide rail arranged above the first workbench 11. The sliding bracket 13 can slide along the slide rail, thereby driving the coiling assembly 10 to move in the X-axis direction. Driven by the sliding bracket 13, the coiling assembly 10 can move along the extension direction of the long side of the battery module and wind the insulating sheet during the movement.

[0057] In one embodiment of the present application, Figure 5As shown, the winding assembly 10 includes a bottom winding mechanism 101, and the bottom winding mechanism 101 includes a first winding shaft 1011 extending along the Y-axis direction. Specifically, the Y-axis direction can be the extension direction of the short side of the battery module, and the first winding shaft 1011 is constructed to rotate along the Y-axis during movement along the X-axis direction to wind the bottom insulating sheet of the battery module located on the first workbench 11. The bottom winding mechanism 101 can be fixed on a sliding bracket 13, and the sliding bracket 13 can move along the X-axis direction and simultaneously drive the first winding shaft 1011 to move along the X-axis direction. Figure 5 As shown, the bottom material rolling mechanism 101 further includes a first material rolling motor 1012, and the first material rolling motor 1012 can drive the first material rolling shaft 1011 to rotate along the Y-axis direction.

[0058] Specifically, an insulating sheet is pasted on the bottom surface of the battery module, and the insulating sheet needs to be peeled off before cutting the battery module. The battery module can be inverted on the first workbench 11, that is, the bottom surface of the battery module faces upward, so that the bottom surface rolling mechanism 101 can peel off the insulating sheet at the bottom. Figure 7 The first winding shaft 1011 is provided with a first slot 10111 extending in the Y-axis direction, and the edge of the bottom insulating sheet of the battery module is configured to extend into the first slot 10111 for fixation. The user can manually peel off the edge of the insulating sheet and push the edge into the first slot 10111 to lock it, and then start the bottom winding mechanism 101. The first winding shaft 1011 moves in the X-axis direction under the driving action of the sliding bracket 13, and at the same time rotates along the Y-axis under the driving action of the first winding motor 1012, thereby winding the insulating sheet on the bottom of the battery module and separating the insulating sheet from the bottom of the battery module.

[0059] In one embodiment of the present application, Figure 5 As shown, the winding assembly 10 includes a vertical winding mechanism 102, and the vertical winding mechanism 102 includes a second winding shaft 1021 extending along the Z-axis direction. Specifically, the Z-axis direction can be the height extension direction of the battery module, and the second winding shaft 1021 is constructed to rotate along the Z-axis during the movement along the X-axis direction to wind the vertical insulating sheet material of the battery module located on the first workbench 11. The vertical winding mechanism 102 can be fixed on a sliding bracket 13, and the sliding bracket 13 can move along the X-axis direction and simultaneously drive the second winding shaft 1021 to move along the X-axis direction. Figure 5 As shown, the facade rolling mechanism 102 also includes a second rolling motor 1022, and the second rolling motor 1022 can drive the second rolling shaft 1021 to rotate along the Z-axis direction.

[0060] Specifically, an insulating sheet is pasted on the facade of the battery module, and the insulating sheet needs to be peeled off before cutting the battery module. The length of the first workbench 11 in the Y-axis direction can be less than the length of the short side of the battery module. When the battery module is placed on the first workbench 11, the two sides of the short side of the battery module can exceed the first workbench 11, so that it is convenient for the facade winding mechanism 102 to peel off the insulating sheet of its facade. Correspondingly, the second winding shaft 1021 can be set at a position beyond the first workbench 11, so as to adapt to the facade of the battery module.

[0061] refer to Figure 7 The second winding shaft 1021 is provided with a second slot 10211 extending in the Z-axis direction, and the edge of the vertical insulating sheet of the battery module is configured to extend into the second slot 10211 for fixation. The user can manually peel off the edge of the insulating sheet and push the edge into the second slot 10211 to lock it, and then start the vertical winding mechanism 102. The second winding shaft 1021 moves along the X-axis direction under the driving action of the sliding bracket 13, and at the same time rotates along the Z-axis under the driving action of the second winding shaft 1021, thereby winding the insulating sheet of the vertical surface of the battery module and separating the insulating sheet from the vertical surface of the battery module.

[0062] As described above, the bottom winding mechanism 101 and the vertical winding mechanism 102 in this embodiment are both arranged on the sliding bracket 13, so the sliding bracket 13 can drive the first winding shaft 1011 and the second winding shaft 1021 to move along the X-axis direction, thereby realizing the simultaneous winding of the insulating plate on the bottom surface of the battery module and at least one vertical surface, thereby improving the working efficiency of the winding device 1.

[0063] The present application uses a coiling device 1 to realize automatic stripping of insulating plates. Compared with the prior art method of manually stripping insulating plates, the coiling device 1 improves the automation level of processing battery modules and saves labor costs. In addition, the automatic winding method of insulating plates also improves the speed and efficiency of processing battery modules.

[0064] refer to Figure 3 The cutting device 2 in the battery module cutting equipment includes a second workbench 21, a cutting assembly 20, and a moving assembly, wherein the cutting assembly 20 is constructed to move along the X-axis, Y-axis, and Z-axis directions on the second workbench 21 through the moving assembly to cut the battery module located on the second workbench 21 and after being wound.

[0065] In a specific embodiment of the present application, the battery module wound by the winding device 1 can be transferred to the second workbench 21 by manual handling, conveyor belt transfer, or hoisting. It should be noted that the battery module on the first workbench 11 can be inverted to facilitate winding the bottom insulating sheet, and when the battery module is transferred to the second workbench 21, it needs to be placed in a positive position with the front side facing up to facilitate cutting.

[0066] The cutting assembly 20 can cut the frame around the battery module, the connecting part in the middle, and the CCS busbar between the battery cells, so as to cut the battery module into small-volume battery blocks or battery cells. The present application does not limit the specific form of the cutting assembly 20, which can be a saw, a milling cutter, a laser, or other structures. In a specific embodiment, reference Figure 8 The cutting assembly 20 is a saw blade, including a saw blade 201 and a cutting motor 202. The cutting motor 202 can drive the saw blade 201 to rotate at high speed, thereby realizing the cutting function. It should be noted that the saw blade 201 is detachably connected to the cutting motor 202. When cutting different parts of the battery module, the user can replace the saw blades 201 of different sizes. For example, when cutting the surrounding frame, a larger saw blade 201 can be used, thereby improving the cutting efficiency; and when cutting the CCS busbar, a smaller saw blade 201 can be used, thereby improving the cutting accuracy.

[0067] In addition, when cutting different parts of the battery module, the speed at which the cutting motor 202 drives the saw blade 201 to rotate and the cutting depth controlled by the motion component 20 can also be different. For example, when cutting the surrounding frame, since this is usually made of metal materials such as aluminum alloy, which has a greater hardness, the saw blade 201 can be controlled to cut at a faster speed; while when cutting the connecting part in the middle, since this is usually made of materials with lower hardness such as nylon, the saw blade 201 can be controlled to cut at a slower speed; when cutting the CCS busbar, the cutting component 20 can be controlled to maintain a shallow cutting depth to prevent cutting too deep and damaging the battery cell.

[0068] The cutting assembly 20 moves along the X-axis, Y-axis, and Z-axis directions through the motion assembly, that is, along the long side, short side, and height direction of the battery module, thereby achieving free movement within a certain spatial range to cut different parts of the battery module. In one embodiment of the present application, the motion assembly includes: an X-axis motion mechanism, a Y-axis motion mechanism, and a Z-axis motion mechanism, which can drive the cutting assembly 20 to move along the X-axis, Y-axis, and Z-axis directions respectively.

[0069] In a specific embodiment, reference Figure 8 and Fig. 9, the Y-axis motion mechanism is constructed to be arranged on the second workbench 21; the X-axis motion mechanism is constructed to be movably connected to the Y-axis motion mechanism; the Z-axis motion mechanism is constructed to be movably connected to the X-axis motion mechanism. The cutting assembly 20 is constructed to move in the Z-axis direction through the Z-axis motion mechanism, and is constructed to move in the X-axis direction under the driving action of the Z-axis motion mechanism, and is constructed to move in the Y-axis direction under the driving action of the X-axis motion mechanism. It should be noted that in addition to the mutual driving method of this embodiment, the X-axis motion mechanism, the Y-axis motion mechanism and the Z-axis motion mechanism can also drive each other in other ways. For example, the cutting assembly 20 can also be set on the Y-axis motion mechanism or the X-axis motion mechanism, and indirectly driven to move by motion mechanisms in other directions.

[0070] like Figure 8 As shown, the X-axis motion mechanism may include a second guide portion 22, and the second guide portion 22 may be a slide rail extending along the X-axis direction. Support rods 221 are respectively provided below the opposite ends of the second guide portion 22, and first sliders 222 are respectively provided at the bottom of the two support rods 221. The Y-axis motion mechanism may include a third guide portion 23 respectively provided on both sides of the second workbench 21, and the third guide portion 23 may be a slide rail extending along the Y-axis direction. The two first sliders 222 are respectively slidably connected to the two third guide portions 23, so that the second guide portion 22 can slide along the Y-axis direction under the driving action of the first slider 222 and the support rod 221.

[0071] like Fig. 9 As shown, the Z-axis motion mechanism may include a fourth guide portion 24, which may be a slide rail extending in the Z-axis direction. The fourth guide portion 24 may be fixedly disposed on the second slider 241, which is slidably connected to the second guide portion 22, so that the fourth guide portion 24 can slide in the X-axis direction under the driving action of the second slider 241. The cutting assembly 20 may be disposed on the third slider 25, which is slidably connected to the fourth guide portion 24, so that the cutting assembly 20 can slide in the Z-axis direction under the driving action of the third slider 25.

[0072] A specific structure of the motion assembly of this embodiment is described above. The cutting assembly 20 can move in the Z-axis direction through the third slider 25 and the fourth guide portion 24; and can move along the second guide portion 22 under the driving action of the second slider 241, so as to move along the X-axis direction; and can move along the third guide portion 23 under the driving action of the first slider 222 and the support rod 221, so as to move along the Y-axis direction. The cutting assembly 20 can move along the X-axis, Y-axis, and Z-axis directions on the second workbench 21 through the motion assembly to cut the battery module located on the second workbench 21 and after winding.

[0073] The present application provides a battery module cutting device including a coiling device 1 and a cutting device 2, thereby realizing the use of one device to complete the two separation processes of winding the insulating plate and cutting the battery module. The battery module can first be wound by the coiling device 1 to peel off the insulating plate attached to the bottom and the vertical surface, and then the battery module with the insulating plate removed is transferred to the cutting device 2 for cutting, wherein the cutting component 20 on the cutting device 2 can be driven by the motion component to move to any position along the X-axis, Y-axis and Z-axis directions, thereby achieving precise cutting.

[0074] In one embodiment of the present application, reference Fig. 9 The cutting assembly 20 is configured to be connected to the Z-axis motion mechanism and rotated along the Z-axis direction. The cutting assembly 20 is configured to rotate to different angles relative to the Z-axis motion mechanism to cut different parts of the battery module. Since the cutting assembly 20 in this embodiment is a circular saw blade 201, and the cutting direction of the saw blade 201 is the tangent direction thereof, refer to Figure 8 The viewing direction, Figure 8 The cutting direction of the saw blade 201 is the Y-axis direction. If the long side frame of the battery module needs to be cut, the cutting assembly 20 needs to be rotated 90 degrees with the Z-axis as the rotation axis, so that the cutting direction of the saw blade 201 is changed to the X-axis direction.

[0075] Specifically, Fig. 9 As shown, a rotating seat 262 is provided on the cutting assembly 20, and a bearing may be provided inside the rotating seat 262. A rotating motor 261 is provided above the cutting assembly 20, and the output shaft of the rotating motor 261 is configured to rotate along the Z axis, and is configured to be connected to the cutting assembly 20 through the rotating seat 262, so as to drive the cutting assembly 20 to rotate to different angles relative to the Z axis motion mechanism, thereby enabling the cutting assembly 20 to cut in different directions, making the cutting assembly 20 more flexible.

[0076] In one embodiment of the present application, structures for fixing the battery module are respectively provided on the first workbench 11 of the winding device 1 and the second workbench 21 of the cutting device 2, thereby preventing the battery module from being displaced during winding or cutting, thereby ensuring the accuracy of cutting.

[0077] Specifically, refer to Figure 4 and Figure 6, two pressing plates 14 are arranged on the first workbench 11, and the two pressing plates 14 are constructed to be spaced apart on both sides of the battery module along the X-axis direction, and are constructed to fit with the vertical surface of the battery module extending along the Y-axis direction. When the battery module is placed on the first workbench 11, the two short side vertical surfaces of the battery module can be clamped between the two pressing plates 14, thereby preventing the battery module from being displaced during winding. When the winding assembly 10 moves along the X-axis direction for winding, it will apply a force in the X-axis direction to the battery module, and the battery module has a tendency to move in the X-axis direction, but because the two short side vertical surfaces of the battery module are clamped between the two pressing plates 14, the battery module cannot move in the X-axis direction.

[0078] like Figure 6 As shown, the pressing plate 14 has an approximately L-shaped cross-section, the horizontal portion of which is fixed on the first workbench 11, and the upwardly folded portion is used to fit with the vertical surface of the battery module, that is, to clamp the short side vertical surface of the battery module. A first waist-shaped hole 141 is provided on the horizontal portion of the pressing plate 14, and a screw can be inserted into the first waist-shaped hole 141 to fix the pressing plate 14 in a suitable position. The first waist-shaped hole 141 allows the pressing plate 14 to have a certain adjustment space, and has more than one fixed position, so that the winding device 1 can be applicable to battery modules of various sizes.

[0079] refer to Figure 8 and Fig.10 , a plurality of positioning blocks 27 are arranged on the second workbench 21, and the plurality of positioning blocks 27 are configured to be spaced at least along the Y-axis direction on both sides of the battery module, and are configured to at least fit with the vertical surface of the battery module extending along the X-axis direction; wherein, the plurality of positioning blocks 27 located on the same side of the battery module are configured to be spaced along the X-axis direction. Since the volume of the positioning blocks 27 is relatively small, a small number of positioning blocks 27 are difficult to play a fixing effect, so a plurality of positioning blocks 27 need to be arranged on one side of the battery module for simultaneous fixing. When the battery module is placed on the second workbench 21, the two long side vertical surfaces of the battery module can be clamped between the two rows of positioning blocks 27 spaced along the Y-axis direction on both sides of the battery module, thereby preventing the battery module from being displaced during cutting. The positioning blocks 27 can not only be spaced along the Y-axis direction on both sides of the battery module, but also spaced along the X-axis direction on both sides of the battery module, thereby clamping the two short side vertical surfaces of the battery module to further enhance the fixing effect.

[0080] like Fig.10As shown, the positioning block 27 has an approximately L-shaped cross-section, the horizontal portion of which is fixed on the second workbench 21, and the folded-up portion thereof is used to fit with the vertical surface of the battery module, that is, at least to clamp the vertical surface of the long side of the battery module. A second waist-shaped hole 271 is provided on the horizontal portion of the positioning block 27, and a screw can be inserted into the second waist-shaped hole 271 to fix the positioning block 27 in a suitable position. The second waist-shaped hole 271 allows the positioning block 27 to have a certain adjustment space, and has more than one fixed position, so that the cutting device 2 can be applied to battery modules of various sizes.

[0082] The winding device 1 and the cutting device 2 of the present application are two separately arranged devices. When the battery module cutting equipment is not in use, in order to save storage space, the winding device 1 can be placed in the first position, that is, the winding device 1 is stored in the storage space 281 at the bottom of the second workbench 21; and when the battery module cutting equipment is needed, the winding device 1 can be moved to the second position first, that is, the winding device 1 can be dragged out from the storage space 281 at the bottom of the second workbench 21, so as to facilitate loading and unloading, and it is easy to place the battery module on the first workbench 11.

[0083] In one embodiment of the present application, Figure 1 As shown, the cutting device 2 further includes a protective cover 29, which is at least arranged outside the movement range of the cutting assembly 20, so as to prevent the debris generated during the cutting process from splashing and injuring people.

[0084] In one embodiment of the present application, the battery module cutting device further includes an anti-leakage pad, which is configured to be laid on the first workbench 11 and / or the second workbench 21. Specifically, Figure 4 and Figure 8 As shown, a first pad 111 can be provided on the first workbench 11, and a second pad 211 can be provided on the second workbench 21. Both the first pad 111 and the second pad 211 can be made of insulating materials, thereby separating the battery module from the first workbench 11 and the second workbench 21, preventing leakage of the battery module and improving the safety of the battery module cutting equipment.

[0086] In actual application, the user can first insert the edges of the bottom and vertical insulating plates of the battery module into the first card slot 10111 and the second card slot 10211 respectively to fix them, and then turn on the switch of the winding device 1, and make the first winding shaft 1011 and the second winding shaft 1021 rotate in the forward direction, so as to simultaneously wind the insulating plates on the bottom and vertical surfaces of the battery module. After the winding is completed, or when the winding assembly 10 moves to the end position along the X axis, the first winding shaft 1011 and the second winding shaft 1021 can be controlled to rotate in the reverse direction, so as to release the forward winding force, so that the user can remove the wound insulating plates.

[0087] The second control unit 32 is configured to at least control the cutting starting point, cutting path, cutting speed and cutting depth of the cutting assembly 20. The second control unit 32 can be the control center of the cutting device 2. Specifically, multiple parameters of the cutting device 2 can be set by touch screen control.
