Referring to fig. 1 to 3, the present application provides a battery module cutting apparatus including a coil stock device 1 and a cutting device 2. Wherein, as shown in fig. 2, the coil stock device 1 comprises a first workbench 11 and a coil stock assembly 10 arranged on the first workbench 11, wherein the first workbench 11 is used for bearing a battery module, and the coil stock assembly 10 is used for winding an insulating plate of the battery module on the first workbench 11 in the process of moving relative to the first workbench 11.

In one embodiment of the present application, referring to fig. 4 and 5, the coil stock apparatus 1 includes a first guide portion 12 and a sliding bracket 13, the first guide portion 12 being configured to be provided on the first table 11 and configured to extend in the X-axis direction. The sliding bracket 13 is configured to be slidably connected to the first guide portion 12, and the coil assembly 10 is configured to be disposed on the sliding bracket 13 and configured to move in the X-axis direction under the driving action of the sliding bracket 13. Specifically, the X-axis direction may be a long-side extending direction of the battery module, and the first guiding portion 12 may be a sliding rail disposed above the first working table 11, along which the sliding bracket 13 may slide, so as to drive the coil assembly 10 to move in the X-axis direction. The coil assembly 10 is driven by the sliding bracket 13 to move along the extending direction of the long side of the battery module, and is wound with the insulating plate in the moving process.

In one embodiment of the present application, as shown in fig. 5, the roll assembly 10 includes a bottom surface roll mechanism 101, the bottom surface roll mechanism 101 including a first roll shaft 1011 extending in the Y-axis direction. Specifically, the Y-axis direction may be a short side extension direction of the battery module, and the first winding shaft 1011 is configured to rotate along the Y-axis during the movement along the X-axis direction to wind the bottom insulating sheet material of the battery module located on the first table 11. The bottom surface material winding mechanism 101 may be fixed on the sliding support 13, and the sliding support 13 may move along the X-axis direction and simultaneously drive the first material winding shaft 1011 to move along the X-axis direction. As shown in fig. 5, the bottom surface winding mechanism 101 further includes a first winding motor 1012, and the first winding motor 1012 can drive the first winding shaft 1011 to rotate along the Y-axis direction.

Specifically, an insulating plate is adhered to the bottom surface of the battery module, and the insulating plate needs to be peeled off before the battery module is cut. The battery module may be inverted on the first table 11, i.e., with the bottom surface of the battery module facing upward, so that the bottom surface winding mechanism 101 is facilitated to peel off the insulating sheet material at the bottom thereof. Referring to fig. 7, a first clamping groove 10111 extending along the Y-axis direction is formed in the first winding shaft 1011, and the edge of the bottom insulating plate of the battery module is configured to extend into the first clamping groove 10111 for fixing. The user can manually peel off the edge of the insulating board, push the edge into the first clamping groove 10111 to clamp, then start the bottom surface coiling mechanism 101, move the first coiling shaft 1011 along the X axis direction under the driving action of the sliding bracket 13, and simultaneously rotate along the Y axis under the driving action of the first coiling motor 1012, thereby coiling the insulating board on the bottom surface of the battery module, and separating the insulating board from the bottom surface of the battery module.

In one embodiment of the present application, as shown in fig. 5, the coil assembly 10 includes a vertical coil mechanism 102, and the vertical coil mechanism 102 includes a second coil shaft 1021 extending along the Z-axis direction. Specifically, the Z-axis direction may be a height extending direction of the battery module, and the second roll shaft 1021 is configured to rotate along the Z-axis during movement along the X-axis direction to roll the elevation insulating sheet material of the battery module located on the first table 11. The vertical surface material winding mechanism 102 can be fixed on the sliding support 13, and the sliding support 13 can move along the X-axis direction and simultaneously drives the second material winding shaft 1021 to move along the X-axis direction. As shown in fig. 5, the elevation roll mechanism 102 further includes a second roll motor 1022, and the second roll motor 1022 can drive the second roll shaft 1021 to rotate along the Z-axis direction.

Specifically, an insulating plate is stuck on the vertical surface of the battery module, and the insulating plate needs to be peeled off before the battery module is cut. The length of the first work table 11 in the Y-axis direction may be smaller than the length of the short side of the battery module, and when the battery module is prevented from being placed on the first work table 11, both sides of the battery module in the short side direction may protrude beyond the first work table 11, thereby facilitating the elevation roll-up mechanism 102 to peel off the insulating sheet material of the elevation thereof. Correspondingly, the second winding shaft 1021 may be arranged at a position beyond the first table 11 so as to be adapted to the elevation of the battery module.

Referring to fig. 7, a second clamping groove 10211 extending along the Z-axis direction is formed in the second roll shaft 1021, and the edge of the vertical insulating plate of the battery module is configured to extend into the second clamping groove 10211 for fixing. The user can manually peel off the edge of the insulating board, push the edge into the second clamping groove 10211 to be clamped firmly, then the elevation coiling mechanism 102 can be started, the second coiling shaft 1021 moves along the X-axis direction under the driving action of the sliding support 13, and simultaneously rotates along the Z-axis under the driving action of the second coiling shaft 1021, so that the insulating board of the elevation of the battery module is coiled, and the insulating board is separated from the elevation of the battery module.

As described above, the bottom surface winding mechanism 101 and the elevation winding mechanism 102 in the present embodiment are both disposed on the sliding bracket 13, so that the sliding bracket 13 can drive the first winding shaft 1011 and the second winding shaft 1021 to move together along the X-axis direction, thereby realizing simultaneous winding of the bottom surface of the battery module and the insulating board on at least one elevation, and improving the working efficiency of the winding device 1.

According to the application, the automatic stripping of the insulating plate is realized by adopting the coil stock device 1, and compared with the mode of manually stripping the insulating plate in the prior art, the automatic degree of battery module processing is improved by adopting the coil stock device 1, and the labor cost is saved. In addition, the mode of automatic winding insulating board has still promoted the speed and the efficiency of handling battery module.

Referring to fig. 3, the cutting device 2 in the battery module cutting apparatus includes a second table 21, a cutting assembly 20, and a moving assembly, wherein the cutting assembly 20 is configured to move on the second table 21 in X-axis, Y-axis, and Z-axis directions by the moving assembly to cut the wound battery module positioned on the second table 21.

In a specific embodiment of the present application, the battery module wound by the winding device 1 can be transferred to the second table 21 by manual handling, conveyor transfer, or hoisting. It should be noted that, the battery module on the first working table 11 may be inverted so as to facilitate winding the bottom insulating board, and the battery module needs to be placed in a right-side up position when being transferred to the second working table 21 so as to facilitate cutting.

The cutting assembly 20 can cut the frame around the battery module, the connecting portion in the middle, and the CCS busbar between the battery cells, thereby cutting the battery module into small-sized battery blocks or battery cells. The specific form of the cutting assembly 20 is not limited in the present application, and may be various structures such as a saw, a milling cutter, a laser, etc. In a specific embodiment, referring to fig. 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 a high speed, thereby realizing a 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, a user can replace saw blades 201 with different sizes, for example, when cutting a peripheral frame, a larger saw blade 201 can be used to improve the cutting efficiency, and when cutting the CCS busbar, a smaller saw blade 201 can be used to improve the cutting accuracy.

In addition, the rotation speed of the cutting motor 202 driving the saw blade 201 to rotate and the depth of the cutting by the moving assembly controlling the cutting assembly 20 may be different when cutting different portions of the battery module. For example, when cutting the surrounding frame, the saw blade 201 is controlled to cut at a higher rotation speed because the frame is usually made of metal material such as aluminum alloy, etc., while the connecting part in the middle of the cutting is controlled to cut at a lower rotation speed because the frame is usually made of material such as nylon, etc., and the cutting assembly 20 is controlled to maintain a shallower cutting depth when cutting the CCS busbar, so as to prevent the cutting from being too deep and damaging the battery cells.

The cutting assembly 20 is moved in the X-axis, Y-axis, and Z-axis directions, that is, in the long side, the short side, and the height direction of the battery module by the moving assembly, thereby realizing 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 comprises an X-axis motion mechanism, a Y-axis motion mechanism and a Z-axis motion mechanism, which are capable of driving the cutting assembly 20 to move along the X-axis, the Y-axis and the Z-axis directions respectively.

In addition to the mutual driving method in this embodiment, the X-axis movement mechanism, the Y-axis movement mechanism, and the Z-axis movement mechanism may be driven by other methods, for example, the cutting assembly 20 may be disposed on the Y-axis movement mechanism or the X-axis movement mechanism and indirectly driven to move by movement mechanisms in other directions.

As shown in fig. 8, the X-axis movement mechanism may include a second guide portion 22, and the second guide portion 22 may be a slide rail extending in the X-axis direction. Support rods 221 are respectively arranged below opposite ends of the second guide portion 22, and first sliding blocks 222 are respectively arranged at bottoms of the two support rods 221. The Y-axis moving mechanism may include third guide portions 23 provided at both sides of the second table 21, respectively, and the third guide portions 23 may be slide rails extending in the Y-axis direction. The two first sliders 222 are slidably connected to the two third guide portions 23, respectively, so that the second guide portions 22 can slide along the Y-axis direction under the driving action of the first sliders 222 and the support rods 221.

As shown in fig. 9, the Z-axis movement mechanism may include a fourth guide portion 24, and the fourth guide portion 24 may be a slide rail extending in the Z-axis direction. The fourth guiding part 24 may be fixedly disposed on the second slider 241, and the second slider 241 is slidably connected to the second guiding part 22, so that the fourth guiding part 24 can slide along 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, and the third slider 25 is slidably connected to the fourth guide portion 24, so that the cutting assembly 20 may slide along the Z-axis direction under the driving action of the third slider 25.

The above describes a specific structure of the moving assembly of the present embodiment, the cutting assembly 20 can move in the Z-axis direction by the third slider 25 and the fourth guide 24, and move along the second guide 22 by the driving of the second slider 241, so as to move along the X-axis direction, and move along the third guide 23 by the driving of the first slider 222 and the support bar 221, so as to move along the Y-axis direction. The cutting assembly 20 can move on the second table 21 along the X-axis, Y-axis, and Z-axis directions by the moving assembly to cut the wound battery module positioned on the second table 21.

The application provides a battery module cutting device comprising a coiling device 1 and a cutting device 2, thereby realizing the two separation processes of coiling an insulating plate and cutting a battery module by adopting one device. The battery module can be firstly coiled and stripped through the coiling device 1 to paste the insulating plate on the bottom surface and the vertical surface, and then the battery module from which the insulating plate is removed is transferred to the cutting device 2 for cutting, wherein the cutting assembly 20 on the cutting device 2 can move to any position along the directions of the X axis, the Y axis and the Z axis under the driving action of the moving assembly, so that accurate cutting is realized.

In one embodiment of the present application, referring to fig. 9, the cutting assembly 20 is configured to be rotatably coupled to the Z-axis moving mechanism in the Z-axis direction, and the cutting assembly 20 is configured to be rotated to different angles with respect to the Z-axis moving mechanism to cut different portions of the battery module. Since the cutting assembly 20 in the present embodiment is a circular saw blade 201, and the cutting direction of the saw blade 201 is the tangential direction thereof, referring to the view direction of fig. 8, the cutting direction of the saw blade 201 shown in fig. 8 is the Y-axis direction, and 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 into the X-axis direction.

Specifically, as shown in fig. 9, the cutting assembly 20 is provided with a rotating seat 262, and a bearing may be provided inside the rotating seat 262. The cutting assembly 20 is provided with a rotation motor 261 above, and an output shaft of the rotation motor 261 is configured to rotate along the Z-axis and is configured to be connected to the cutting assembly 20 through a rotation seat 262 so as to drive the cutting assembly 20 to rotate to different angles relative to the Z-axis movement mechanism, thereby enabling the cutting assembly 20 to cut along different directions, and enabling the cutting assembly 20 to be more flexible.

In one embodiment of the present application, the first table 11 of the coil stock apparatus 1 and the second table 21 of the cutting apparatus 2 are respectively provided with structures for fixing the battery module, thereby preventing the battery module from being displaced when winding or cutting is performed, and further ensuring the accuracy of cutting.

Specifically, referring to fig. 4 and 6, two pressing plates 14 are disposed on the first table 11, and the two pressing plates 14 are configured to be spaced apart on both sides of the battery module in the X-axis direction and to be attached to a vertical surface of the battery module extending in the Y-axis direction. When the battery module is placed on the first table 11, the two short side elevation surfaces of the battery module can be clamped between the two pressing plates 14, thereby preventing the battery module from being displaced when winding. The coil assembly 10 applies force in the X-axis direction to the battery module when moving in the X-axis direction, and the battery module has a tendency to move in the X-axis direction, but since the two short side faces of the battery module are clamped between the two pressing plates 14, the battery module cannot move in the X-axis direction.

As shown in fig. 6, the pressing plate 14 has an approximately L-shaped cross section, a horizontal portion of which is fixed to the first table 11, and an upwardly folded portion of which is used for fitting with the vertical face of the battery module, i.e., for clamping the short side vertical face of the battery module. A first waist-shaped hole 141 is formed in the horizontal portion of the pressing plate 14, and a screw may be inserted into the first waist-shaped hole 141, thereby fixing the pressing plate 14 in place. The first waist-shaped hole 141 allows the pressing plate 14 to have a certain adjusting space and not only one fixing position, so that the coil stock device 1 can be suitable for battery modules of various sizes.

Referring to fig. 8 and 10, the second table 21 is provided with a plurality of positioning blocks 27, the plurality of positioning blocks 27 being configured to be spaced apart from each other at least in the Y-axis direction on both sides of the battery module and to be attached to at least a vertical surface of the battery module extending in 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 apart from each other in the X-axis direction. Since the positioning blocks 27 have a relatively small volume, a small number of positioning blocks 27 are difficult to fix, and thus a plurality of positioning blocks 27 are required to be arranged on one side of the battery module to fix at the same time. When the battery module is placed on the second table 21, the two long-side elevation surfaces of the battery module can be clamped between the two alignment blocks 27 spaced apart on both sides of the battery module in the Y-axis direction, thereby preventing the battery module from being displaced when cutting is performed. The positioning blocks 27 can be distributed at intervals along the Y-axis direction on two sides of the battery module, and can be distributed at intervals along the X-axis direction on two sides of the battery module, so that two short side vertical faces of the battery module are clamped, and the fixing effect is further improved.

As shown in fig. 10, the positioning block 27 has an approximately L-shaped cross section, the horizontal portion of which is fixed to the second table 21, and the upwardly folded portion of which is used for fitting with the vertical face of the battery module, i.e., at least for clamping the long-side vertical face of the battery module. A second waist-shaped hole 271 is formed in the horizontal portion of the positioning block 27, and a screw may be inserted into the second waist-shaped hole 271 to fix the positioning block 27 in place. The second waist-shaped hole 271 allows the positioning block 27 to have a certain adjustment space and not only one fixing position, so that the cutting device 2 can be applied to battery modules of various sizes.

In the practical application process, the user can clamp the edges of the insulating plates of the bottom surface and the vertical surface of the battery module into the first clamping groove 10111 and the second clamping groove 10211 respectively for fixing, then turn on the switch of the material coiling device 1, and make the first material coiling shaft 1011 and the second material coiling shaft 1021 rotate along the forward rotation direction, thereby coiling the insulating plates on the bottom surface and the vertical surface of the battery module simultaneously. After winding, 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 along the reverse direction, so as to release the winding force of forward rotation, and facilitate the user to take down the wound insulating board.

The second control unit 32 is configured to control at least a cutting start point, a cutting path, a cutting speed and a cutting depth of the cutting assembly 20. The second control unit 32 may be a control center of the cutting device 2, and in particular, may set a plurality of parameters of the cutting device 2 in a touch screen control manner. By means of the second control unit 32, the user can set the cutting position, for example, can select to cut the left CCS busbar, the right CCS busbar, the left riser, the right riser, the left cross plate, the right cross plate or the center nylon, and further set the specific depth of each cutting position, and can control the spatial coordinate position of the cutting assembly 20 to set the starting point of the cutting and the specific path.
