[0073] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0074] In the production process of the battery cell module, after a plurality of battery cells are stacked to form the battery cell module, in order to ensure the structural stability of the battery cell module, the battery cell module also needs to be fixed by a binding belt.

[0075] Currently, in order to attach the strapping tape to the battery cell module, an extrusion device is needed to compress the battery cell module, making it shorter and easier to attach the strapping tape. Existing extrusion devices typically have two spaced-apart extrusion mechanisms at each extrusion station, which extrude the battery cell module from both ends along its length. However, in actual production, to improve efficiency, multiple battery cell modules are extruded simultaneously. This results in existing extrusion devices being structurally complex, costly, and space-consuming.

[0076] Therefore, this application proposes a cell module extrusion device, please refer to [link to relevant documentation]. Figure 1 As shown, the battery cell module extrusion device proposed in this application includes a base 1 and at least one extrusion mechanism 2. The extrusion mechanism 2 includes a first extrusion part 20, two second extrusion parts 21, and two bearing parts 22. The two second extrusion parts 21 are respectively disposed on the base in the first horizontal direction. Figure 1 At both ends of the X direction, the first extrusion part 20 is disposed between the two second extrusion parts 21 to form two extrusion stations 10 extending along the first horizontal direction on the base 1. Each extrusion station 10 is provided with a support part 22, and the support part 22 is configured to at least support the battery cell module 3 on the corresponding extrusion station 10. Each second extrusion part 21 is configured to push or release the battery cell module 3 supported by the corresponding support part 22 near the first end of the second extrusion part 21, and the first extrusion part 20 is configured to simultaneously push or release the battery cell module 3 supported by both support parts 22 near the second end of the first extrusion part 20.

[0077] The battery cell module extrusion device proposed in this application achieves synchronous extrusion of two battery cell modules 3 through the cooperation of a first extrusion section 20, two second extrusion sections 21 and two bearing sections 22, resulting in high working efficiency; moreover, the two extrusion stations 10 share a first extrusion section 20, which simplifies the overall structure of the battery cell extrusion device, reduces costs and occupies less space.

[0078] Please see Figures 1 to 4 As shown, in one embodiment, the first pressing part 20 includes a first driving assembly 23 and two first pushing members 24. The two first pushing members 24 are reciprocally slidably mounted on the base 1 along a first horizontal direction. The driving end of the first driving assembly 23 is connected to the two first pushing members 24. The first driving assembly 23 is configured to drive the two first pushing members 24 to move closer or further away from each other. The first driving assembly 23 drives the two first pushing members 24 to move further away from each other so that the two first pushing members 24 simultaneously push against the second ends of the battery cell modules 3 carried by the two carrier parts 22. The first driving assembly 23 drives the two first pushing members 24 to move closer to each other so that the two first pushing members 24 simultaneously release the second ends of the battery cell modules 3 carried by the two carrier parts 22.

[0079] As can be seen, through the cooperation of the first driving component 23 and the two first pushing members 24, the two first pushing members 24 are moved away from each other or moved closer to each other, thereby enabling the two first pushing members 24 to simultaneously push or release the second end of the battery cell module 3 carried by the two bearing parts 22, providing a first extrusion part 20 with a simple structure and stable and reliable operation.

[0080] In one embodiment, the first drive assembly 23 includes a first drive member 230, a cam 231, a mounting frame 232, and a reset drive member. The cam 231 is rotatably mounted on the base 1 and located between two first push members 24. The drive end of the first drive member 230 is connected to the cam 231, and the first drive member 230 is configured to drive the cam 231 to rotate by a preset angle. The mounting frame 232 is erected above the two first push members 24 and the cam 231. The bottom end of the mounting frame 232 is mounted on the base 1, and the fixed end of the first drive member 230 is mounted on the mounting frame 232. The first ends of the two first push members 24 abut against the opposite side walls of the cam 231, and the second ends of the two first push members 24 are used to push against the second end of the battery cell module 3 carried on the corresponding support portion 22. The first drive member 230 drives the cam 231 to rotate by a preset angle so as to push the two first push members 24 away from each other through the cam 231. The reset drive member is configured to drive the two first push members 24 to move closer to each other.

[0081] Specifically, the first driving component 230 is a rotary cylinder, and the cam 231 is rotatably mounted on the base 1 via a camshaft. The rotating shaft of the rotary cylinder is coaxially connected to the camshaft via a coupling.

[0082] As can be seen, by driving the cam 231 to rotate by a preset angle through the first driving member 230, the cam 231 pushes the two first pushing members 24 away from each other, providing a first driving component 23 with high control precision, large load bearing capacity and long service life; at the same time, by driving the two first pushing members 24 away from each other through the reset driving member, the two first pushing members 24 automatically reset after releasing the second end of the battery cell module 3 carried by the two bearing parts 22.

[0083] In one embodiment, each of the first ends of the two first push members 24 is equipped with a self-rotating roller 240, which abuts against the side wall of the cam 231.

[0084] It can be seen that by setting a roller 240 at the first end of the first pushing member 24, the first pushing member 24 and the side wall of the cam 231 are in rolling contact, which reduces the friction when the cam 231 pushes the first pushing member 24, greatly reduces the wear on the cam 231, and extends the service life of the cam 231. The rolling contact between the roller 240 and the cam 231 is also less than the pushing force required for the hard contact between the first pushing member 24 and the cam 231, which reduces the power required for the first drive assembly 23 to push the first pushing member 24 and reduces the power consumption of the equipment.

[0085] In one embodiment, two first pushing members 24 are slidably mounted on the limiting frame 233. The limiting frame 233 is provided with sliders 234 on both outer walls along the first horizontal direction. The two first pushing members 24 are respectively provided with slide rails 235 that cooperate with the sliders 234. The slide rails 235 extend along the first horizontal direction. The first pushing members 24 are provided with waist holes 241 extending along the first horizontal direction. The first pressing part 20 also includes two limiting rods 236 provided on the limiting frame 233. The two limiting rods 236 are respectively inserted into the waist holes 241 of the two first pushing members 24.

[0086] Specifically, the limiting frame 233 has a limiting cavity for installing the first pushing member 24. The first end of the first pushing member 24 passes through the limiting cavity and extends out of the limiting frame 233. The waist hole 241 is opened at the first end of the first pushing member 24. The limiting frame 233 has a through hole communicating with the limiting cavity. The limiting rod 236 passes through the through hole and is inserted into the waist hole 241 of the corresponding first pushing member 24.

[0087] Specifically, a push block 242 is installed at the second end of the first push member 24, and a plurality of protrusions 243 in the shape of matching the end plate of the battery cell module 3 are provided on the push surface of the push block 242.

[0088] As can be seen, by setting a limiting frame 233 and connecting the limiting frame 233 to the first pushing member 24 through the slider 234 and the slide rail 235, the sliding direction of the first pushing member 24 is limited, thereby improving the smoothness of the sliding of the first pushing member 24. By opening a waist hole 241 on the first pushing member 24 and inserting a limiting rod 236 into the waist hole 241, the sliding stroke of the first pushing member 24 is limited, which also ensures the stable movement of the roller 240 and prevents the support of the roller 240 from deforming after long-term operation.

[0089] In one embodiment, a convex arc surface 2310 extending outward from the middle of the cam 231 is provided on the side wall of the cam 231. When the cam 231 rotates at a preset angle, the first end of the first pusher 24 moves from the middle of the cam 231 along the convex arc surface 2310 of the cam 231.

[0090] It can be seen that by providing a convex arc surface 2310 on the side wall of the cam 231, a small rotation angle of the cam 231 can be converted into a large horizontal movement stroke of the first push member 24; at the same time, it is also convenient for the first push member 24 to reset.

[0091] In one embodiment, the reset drive includes two reset cylinders 237, the cylinder bodies of the two reset cylinders 237 are respectively fixed on the first first push member 24, and the telescopic ends of the two reset cylinders 237 are respectively fixed on the second first push member 24.

[0092] It can be seen that by driving the two first pushing members 24 to move closer to each other and reset by two reset cylinders 237, a stable and reliable reset drive is provided.

[0093] In one implementation, the reset drive is a spring (not shown in the figure), with both ends of the spring fixed to the two first push members 24 respectively.

[0094] It can be seen that by using the elastic force of the spring itself to drive the two first pushing parts 24 to move closer to each other and reset, a simple and low-cost reset drive is provided.

[0095] Please see Figure 1 and Figure 5 As shown, in one embodiment, the second extrusion section 21 includes a second drive assembly 25 and a second pusher 26. The second pusher 26 is reciprocally mounted on the base 1 in a first horizontal direction. The drive end of the second drive assembly 25 is connected to the second pusher 26. The second drive assembly 25 is configured to drive the second pusher 26 to move closer to or further away from the corresponding extrusion station 10 in the first horizontal direction, so as to push or release the first end of the battery cell module 3 carried by the corresponding carrier section 22 through the second pusher 25. The second drive assembly 25 includes a second drive member 250, a first pulley 251, a second pulley 252, a transmission belt 253, a ball screw 254, and a screw nut. The first pulley 251 and the second pulley 252 are spaced apart and rotatably mounted on the base. On the base 1, a transmission belt 253 is sleeved on the first pulley 251 and the second pulley 252. The driving end of the second driving member 250 is connected to the first pulley 251, and the second driving member 250 is configured to drive the first pulley 251 to rotate. A ball screw 254 is rotatably mounted on the base 1 along its own axis and extends in the first horizontal direction. A screw nut is sleeved on the ball screw 254 and is fixedly connected to the second pushing member 26. The ball screw 254 is coaxially connected to the second pulley 252. The second driving member 250 drives the first pulley 251 to rotate, so as to drive the second pulley 252 to rotate through the transmission belt 253, thereby driving the ball screw 254 to rotate along its own axis, and driving the second pushing member 26 to reciprocate in the first horizontal direction through the screw nut.

[0096] Specifically, the second drive component 250 is a motor.

[0097] Specifically, the pressing end of the second pushing member 26 is equipped with a pushing block 242, and the pushing surface of the pushing block 242 is provided with a plurality of protrusions 243 that match the end plate shape of the battery cell module 3.

[0098] As can be seen, by driving the second push member 26 to move through the second drive assembly 25, the second push member 26 pushes or releases the first end of the battery cell module 3 carried by the corresponding bearing part 22, providing a second extrusion part 21 with a simple structure and stable and reliable operation; through the cooperation of the second drive member 250, the first pulley 251, the second pulley 252, the transmission belt 253, the ball screw 254 and the screw nut, the second push member 26 is driven to reciprocate along the first horizontal direction, providing a second drive assembly 25 with high driving efficiency, smooth operation and high driving accuracy; at the same time, the second drive assembly 25 adopts the transmission form of synchronous belt plus screw nut, so that the second drive member 250 is completely located above the base 1, avoiding the second drive member 250 from being exposed outside the base 1, and reducing the space occupied in the horizontal direction.

[0099] Please see Figure 1 , Figures 6 to 9 As shown, in one embodiment, the carrier 22 is also configured to straighten the battery cell module 3 on the corresponding extrusion station 10. The carrier 22 includes a third drive assembly 27, a first carrier member 28, and a second carrier member 29. The first carrier member 28 and the second carrier member 29 are slidably oriented along a second horizontal direction. Figure 1 The third drive assembly 27 is configured to drive the first support member 28 and the second support member 29 to move closer or further away from each other, with the first horizontal direction and the second horizontal direction being perpendicular. After the battery cell module 3 is placed on the first support member 28 and the second support member 29, the third drive assembly 27 drives the first support member 28 and the second support member 29 to move closer to each other, so that the first support member 28 and the second support member 29 abut against the bottom of both sides of the battery cell module 3 extending along the first horizontal direction.

[0100] It can be seen that the cooperation of the third drive component 27, the first carrier component 28 and the second carrier component 29 realizes the bearing and automatic alignment of the battery cell module 3, thereby improving the processing quality of the battery cell module 3; at the same time, it can be adapted to battery cell modules 3 of different specifications, with good compatibility.

[0101] In one embodiment, the third drive assembly 27 includes a third drive member 270 and a first slide plate 271. The first slide plate 271 is reciprocally mounted on the base 1 in a first horizontal direction. The drive end of the third drive member 270 is connected to the first slide plate 271. The third drive member 270 is configured to drive the first slide plate 271 to reciprocate in the first horizontal direction. An inclined first groove 2710 is provided on the first slide plate 271. A first guide wheel 280 that fits into the first groove 2710 and is rotatable is mounted on the first support member 28. The third drive member 270 drives the first slide plate 271 to reciprocate in the first horizontal direction, so that the first support member 28 moves closer to or away from the second support member 29 through the cooperation of the first groove 2710 and the first guide wheel 280.

[0102] Specifically, the third drive unit 270 adopts a conventional lead screw linear module, which will not be described in detail here.

[0103] It can be seen that, through the cooperation of the third driving component 270, the first sliding plate 271, the first sliding groove 2710 and the first guide wheel 280, the first bearing component 28 is driven to move closer to or away from the second bearing component 29 to carry the battery cell module 3 to be extruded and to regulate the carried battery cell module 3, thus providing a third driving component 27 with stable and reliable driving and long service life.

[0104] In one embodiment, the third drive assembly 27 further includes a fourth drive member 272 and a second slide plate 273. The second slide plate 273 is mounted on the base 1 and is reciprocally movable along a first horizontal direction. The drive end of the fourth drive member 272 is connected to the second slide plate 273. The fourth drive member 272 is configured to drive the second slide plate 273 to reciprocate along the first horizontal direction. An inclined second slide groove 2730 is provided on the second slide plate 273. A second guide wheel 290 that fits into the second slide groove 2730 and is rotatable is mounted on the second support member 29. The fourth drive member 272 drives the second slide plate 273 to reciprocate along the first horizontal direction, so that the second support member 29 moves closer to or away from the first support member 28 through the cooperation of the second slide groove 2730 and the second guide wheel 290.

[0105] Specifically, the fourth drive unit 272 adopts a conventional lead screw linear module, which will not be described in detail here.

[0106] As can be seen, through the cooperation of the fourth driving component 272, the second sliding plate 273, the second sliding groove 2730, and the second guide wheel 290, the second bearing component 29 is driven to move closer to and away from the first bearing component 28. This provides a third driving component 27 that can independently drive the first bearing component 28 and the second bearing component 29 to move, which is stable, reliable, and has a long service life.

[0107] In one embodiment, the cell module extrusion device includes two extrusion mechanisms 2, which are arranged side by side in the second horizontal direction. Each pair of extrusion stations 10 in the two extrusion mechanisms 2 corresponds to each other in the second horizontal direction. Two adjacent second bearing members 29 in the two extrusion mechanisms 2 share a set of fourth drive members 272 and second slide plate 273. The second slide plate 273 is provided with two second slide grooves 2730 with opposite inclination directions. The second guide wheels 290 of the two second bearing members 29 are respectively located in one of the second slide grooves 2730.

[0108] It can be seen that by setting two sets of extrusion mechanisms 2, the extrusion device has four extrusion stations 10, which can simultaneously extrude four battery cell modules 3, further improving the extrusion efficiency of the battery cell modules 3; at the same time, the two sets of extrusion mechanisms 2 share a set of fourth drive components 272 and second slide plate 273 on the two adjacent second bearing components 29 in the second horizontal direction, which further simplifies the overall structure of the extrusion device and reduces costs.

[0109] In one embodiment, the base 1 is provided with a clearance hole 11 extending in the first horizontal direction. The battery cell module 3 is fed into the extrusion station 10 below the base 1 through the clearance hole 11 via a conveying mechanism. The conveying mechanism is provided with a bearing component for bearing the battery cell module 3 to be extruded. Both the first bearing member 28 and the second bearing member 29 are provided with clearance notches 281 for avoiding the bearing component.

[0110] As can be seen, by setting the clearance hole 11 on the base 1, the battery cell module 3 can be fed into the extrusion station 10 below the base 1 through the clearance hole 11 via the conveying mechanism. It has high adaptability and can be adapted to application scenarios where the battery cell module 3 is fed into the extrusion station 10 from above or below.

[0113] S2, the first support member 28 and the second support member 29 of the support part 22 of the two extrusion stations 10 approach each other to support and straighten the battery cell module 3 on the corresponding extrusion station 10;

[0114] S3, while the two second extrusion sections 21 push the battery cell module 3 carried by the bearing section 22 on the corresponding extrusion station 10 close to one end of the second extrusion section 21, the first extrusion section 20 simultaneously pushes the battery cell module 3 carried by the bearing section 22 on the two extrusion stations 10 close to one end of the first extrusion section 20, so as to perform synchronous extrusion on the battery cell module 3 on the two extrusion stations 10.

[0115] The battery cell module extrusion device proposed in this application has the following advantages:

[0116] 1) The first extrusion section can simultaneously push the battery cell modules on two extrusion stations to cooperate with the two second extrusion sections, thereby achieving synchronous extrusion of the two battery cell modules, resulting in high work efficiency; at the same time, it simplifies the overall structure, reduces costs, and occupies less space.

[0117] 2) The first drive assembly uses a cam to drive the two first push parts to move away from each other, which has high control accuracy, large load capacity and long service life;

[0118] 3) It is equipped with two extrusion mechanisms, which can simultaneously extrude four battery cell modules. A worker is arranged on the outside of the first extrusion section of each extrusion mechanism to operate the battery cell modules on the two extrusion stations on that side, saving manpower and increasing work efficiency.

[0119] 4) The support unit can both support the battery cell module and regulate the supported battery cell module, and the support unit can be compatible with battery cell modules of different specifications;

[0120] 5) The battery cell module can be fed into the extrusion station from above or below according to the actual application needs, which has high adaptability.
