Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to a stacking device. Background Technology

[0002] During the production of lithium-ion battery cells, the cells are generally designed by stacking the separator, negative electrode, separator, and positive electrode in sequence. To complete the stacking process, a stacking device is usually used.

[0003] Currently, lamination devices typically use a lead screw and guide rail structure for drive. Due to the high level of diaphragm dust in the production environment, dust inevitably falls onto the lead screw or guide rail. Since the lead screw and guide rail lack dustproof and dust-removal mechanisms, dust accumulation on the lead screw accelerates wear, leading to frequent damage and high maintenance frequency, which is detrimental to reducing production costs. Utility Model Content

[0004] This invention provides a stacking device that can achieve dust prevention, reduce maintenance frequency, and reduce production costs.

[0005] This utility model provides a stacking device, including two blades, a first drive module, a first guide rail, two sets of adapter components, and a first mounting plate;

[0006] The two blades are arranged along a first direction, and the blades and the first guide rail are respectively disposed on opposite sides of the first mounting plate along a second direction. The first guide rail extends along the first direction, and the first direction is perpendicular to the second direction.

[0007] The first drive module includes an active rotation structure, a driven rotation structure, and a synchronous belt. The active rotation structure and the driven rotation structure are arranged along the first direction. The synchronous belt is a ring structure. The active rotation structure and the driven rotation structure are respectively connected to the synchronous belt for transmission.

[0008] The blade is connected to the timing belt via the adapter assembly. The blade and the timing belt are arranged along a third direction, which is perpendicular to the first direction and perpendicular to the second direction. The adapter assembly is slidably mounted on the first guide rail along the first direction. The first drive module is used to drive the first blade and the second blade to move closer to or further away from each other along the first direction.

[0009] The laminating device provided by this utility model adopts a synchronous belt drive structure. The synchronous belt and the first guide rail are connected through an adapter component, and there is no direct contact between the synchronous belt and the first guide rail, avoiding wear between them. Compared with the screw drive structure, this reduces the frequency of maintenance. Furthermore, a first mounting plate is provided, with the blade and the first guide rail positioned on opposite sides of the mounting plate. Since the first mounting plate acts as a dustproof barrier, the first guide rail mounted on the side of the mounting plate away from the blade prevents dust accumulation, thus improving the dustproof effect. Therefore, the laminating device provided by this utility model, through the combined action of the synchronous belt and the first mounting plate, improves the dustproof effect, reduces the maintenance frequency, and helps to reduce production costs.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] refer to Figure 1 and Figure 2 The stacking device in this embodiment may include a first mounting plate 100, two blades 200, a first guide rail 300, two sets of adapter assemblies 400, and a first drive module 500. The two blades 200 are disposed on one side of the first mounting plate 100, and the first guide rail 300 is disposed on the other side of the first mounting plate 100. In other words, the first mounting plate 100 has a front and a back side, with the blades 200 disposed on the front side and the first guide rail 300 disposed on the back side.

[0024] Two blades 200 are arranged along a first direction, and each blade 200 can move along the first direction, allowing them to move closer to or further apart. When the two blades 200 move closer, they cooperate to complete the stacking process. After the stacking process is completed, the two blades move further apart to facilitate the removal of the stacked battery cell.

[0025] For ease of spatial description, the arrangement direction of the front and back of the first mounting plate 100 is defined as the second direction, which is perpendicular to the first direction. A third direction is also defined, which is perpendicular to both the first and second directions.

[0026] Continue to refer to Figure 1 The first drive module 500 may include an active rotating structure 510, a driven rotating structure 520, and a synchronous belt 530. The synchronous belt 530 has a ring structure, and the active rotating structure 510 and the driven rotating structure 520 are respectively connected to the synchronous belt 530 for transmission. The first drive module 500 may also include a first drive device 540, which is used to drive the active rotating structure 510 to rotate. When the active rotating structure 510 rotates, it can drive the synchronous belt 530 to move. When the synchronous belt 530 moves, it can drive the driven rotating structure 520 to rotate. Thus, with the cooperation of the active rotating structure 510 and the driven rotating structure 520, the linear motion of the synchronous belt 530 can be realized.

[0027] For example, the first driving device 540 may be a servo motor, the active rotation structure 510 may be a first pulley, and the driven rotation structure 520 may be a second pulley. The axes of the first and second pulleys are parallel. The circumferential surfaces of the first and second pulleys are respectively provided with meshing teeth, and the inner surface of the synchronous belt 530 is also provided with belt teeth corresponding to the meshing teeth. The first and second pulleys are respectively connected to the synchronous belt 530 through the meshing of their meshing teeth. The output shaft of the servo motor is connected to the first pulley, and the axis of the output shaft coincides with the axis of the first pulley, thereby driving the first pulley to rotate around its own axis.

[0028] Please refer to the above. Figure 1 and Figure 3 The active rotating structure 510 and the driven rotating structure 520 are arranged along a first direction. Each blade 200 is connected to the synchronous belt 530 via a set of adapter components 400. In this case, the synchronous belt 530 and the blades 200 can be considered spatially arranged along a third direction, so that the synchronous belt 530 drives the two blades 200 to move along the first direction. As mentioned above, the synchronous belt 530 is a ring structure. In this case, the synchronous belt 530 can be considered to include a first side 531 and a second side 532 arranged in parallel. When the first drive module 500 is working, the first side 531 and the second side 532 move in opposite directions. One set of adapter components 400 is connected to the first side 531 of the synchronous belt 530, and the other set of adapter components 400 is connected to the second side 532 of the synchronous belt 530. When the first drive module 500 is working, it can drive the two blades 200 to move closer to each other or further away from each other.

[0029] Please refer to the above. Figures 1 to 3The first guide rail 300 extends along a first direction, and each set of adapter components 400 is also mounted on the first guide rail 300. Furthermore, the adapter components 400 can slide relative to the first guide rail 300 along the first direction. When the first drive module 500 drives the adapter components 400 to move, the adapter components 400 can slide on the first guide rail 300 along the first direction, so as to make the movement of the blade 200 smoother.

[0030] It is understandable that, since this embodiment requires the two blades 200 to be brought close to each other to complete the stacking work, when the first driving device 540 is set as a servo motor, the servo motor can accurately control the movement path of the synchronous belt 530, thereby effectively avoiding the collision between the two blades 200.

[0031] Furthermore, in this embodiment, when the first guide rail 300 is inverted and mounted on the back of the first mounting plate 100, the first mounting plate 100 can also act as a dustproof plate, thereby preventing dust from accumulating on the first guide rail 300 and achieving effective dust prevention. Moreover, in this embodiment, the synchronous belt 530 transmission method does not directly contact the first guide rail 300, eliminating wear between them and extending the service life of the synchronous belt 530, thus facilitating maintenance. The synchronous belt 530 transmission structure is lower in cost than the lead screw transmission structure, which also helps reduce production costs.

[0032] In some embodiments, continue to refer to Figure 2 The adapter assembly 400 may include a first adapter block 410 and a second adapter block 420. The first and second ends of the first adapter block 410 are respectively connected to the blade 200 and the timing belt 530. The first and second ends of the second adapter block 420 are respectively connected to the first adapter block 410 and the first guide rail 300.

[0033] For details, please refer to Figure 4 The first adapter block 410 may include a first connecting plate 411 and a second connecting plate 412 that are perpendicular to each other, so that the first adapter block 410 can be L-shaped as a whole. The first connecting plate 411 is located on the front side of the first mounting plate 100, and the blade 200 can be fixed to the side of the first connecting plate 411 opposite to the first mounting plate 100. The second connecting plate 412 can be connected to the end of the first connecting plate 411 away from the blade 200, and the second connecting plate 412 is connected to the timing belt 530.

[0034] The second adapter block 420 may include a third connecting plate 421 and a fourth connecting plate 422 that are perpendicular to each other, so that the second adapter block 420 can be L-shaped as a whole. The third connecting plate 421 is connected to the first connecting plate 411. At this time, the third connecting plate 421 and the second connecting plate 412 are parallel and spaced apart, so that the synchronous belt 530 can pass through the space between the third connecting plate 421 and the second connecting plate 412. The fourth connecting plate 422 is located on the side of the first mounting plate 100 opposite to the first connecting plate 411. One end of the fourth connecting plate 422 is connected to the third connecting plate 421, and the other end is connected to the first guide rail 300 through a slider.

[0035] In this embodiment, reference is also made to Figure 4 and Figure 5 A fixing plate 440 can also be provided, which is parallel to the second connecting plate 412 and located on opposite sides of the synchronous belt 530. The second connecting plate 412 and the fixing plate 440 can be fixed together, for example, with multiple screws. This not only facilitates fixing between the two but also facilitates later maintenance. The synchronous belt 530 is snapped between the second connecting plate 412 and the fixing plate 440, so that the synchronous belt 530 can remain relatively fixed to both the second connecting plate 412 and the fixing plate 440.

[0036] The fourth connecting plate 422 is parallel to the first connecting plate 411, and is also parallel to the first mounting plate 100. Thus, when the timing belt 530 moves along the first direction, the second connecting plate 412 and the third connecting plate 421 can respectively drive the first connecting plate 411 and the fourth connecting plate 422 relative to the first mounting plate 100 along the first direction. The first connecting plate 411 can also directly contact the first mounting plate 100. Since the first connecting plate 411 is parallel to the first mounting plate 100, the first mounting plate 100 not only provides stable support for the first connecting plate 411, but also ensures smooth movement of the first connecting plate 411.

[0037] As an optional implementation scheme, it is also referred to. Figure 3 , Figure 5 and Figure 6The second connecting plate 412 or the fixing plate 440 has a plurality of spaced-apart first protrusions 430 on the side facing the synchronous belt 530. Correspondingly, the synchronous belt 530 has a plurality of spaced-apart second protrusions 533 on the side facing the second connecting plate 412 or the fixing plate 440. When the synchronous belt 530 is fixed to the second connecting plate 412 and the fixing plate 440, each second protrusion 533 can be engaged in the gap between two adjacent first protrusions 430, and each first protrusion 430 can be engaged in the gap between two adjacent second protrusions 533. Thus, the synchronous belt 530 is fixed to the second connecting plate 412 or the fixing plate 440 through the interlocking structure.

[0038] It is worth noting that, as mentioned above, when the inner surface of the timing belt 530 is provided with teeth, the teeth can be used as the second protrusion 533. In this case, the multiple first protrusions 430 provided on the second connecting plate 412 or the fixing plate 440 can be toothed clamps, which engage with the teeth to fix the timing belt 530 to the second connecting plate 412, or to the fixing plate 440.

[0039] In some embodiments, continue to refer to Figure 1 The first mounting plate 100, the blade 200, and the first drive module 500 can also move along the second direction. In practical applications, the second direction can also be understood as the vertical direction, that is, the height of the blade 200 is adjustable to adapt to the stacking process of cells of different sizes.

[0040] Based on this, the stacking device in this embodiment may further include a second mounting plate 600 and a second driving module 700, wherein the first mounting plate 100 and the first driving module 500 may be fixedly connected to the second mounting plate 600, and the second driving module 700 may be used to drive the second mounting plate 600 to move along the second direction.

[0041] The second mounting plate 600 may be located on the side of the first mounting plate 100 away from the timing belt 530 and perpendicular to the first mounting plate 100. In addition, the second mounting plate 600 extends in the direction of the blade 200 pointing towards the first mounting plate 100.

[0042] Please refer to the above. Figure 7 and Figure 8 The second drive module 700 may include a second drive device 710 and a cam linkage mechanism 720. The cam linkage mechanism 720 is connected to the second mounting plate 600. The second drive device 710 is used to drive the cam linkage mechanism 720 to move, thereby causing the second mounting plate 600 to move in the second direction.

[0043] Specifically, the cam-linkage mechanism 720 may include a cam 721, a rotating shaft 723, and a connecting rod 722. The second drive device 710 may be, for example, a servo motor. In this case, the output shaft of the servo motor is connected to the cam 721 to drive the cam 721 to rotate about a first axis perpendicular to the second mounting plate 600. The rotating shaft 723 is connected to the free end of the cam 721. One end of the connecting rod 722 has a first mounting hole 7221. The rotating shaft 723 can be mounted in the first mounting hole 7221 via a bearing, allowing the rotating shaft 723 to rotate relative to the connecting rod 722 about a second axis (i.e., the axis of the rotating shaft 723). Here, the second axis is perpendicular to the second mounting plate 600, and the second axis is not collinear with the first axis.

[0044] Furthermore, the other end of the connecting rod 722 is provided with a second mounting hole 7222, and the second mounting plate 600 is provided with a third mounting hole (not shown in the figure) coaxially arranged with the second mounting hole 7222. The connecting rod 722 and the second mounting plate 600 can be connected by bolts 730 passing through the second mounting hole 7222 and the third mounting hole. In addition, the bolts 730 can also be installed in the second mounting hole 7222 by bearings, so that the connecting rod 722 can also rotate relative to the second mounting plate 600 around the third axis (i.e., the axis of the second mounting hole 7222). The third axis is perpendicular to the second mounting plate 600, and the third axis is not collinear with the first axis or the second axis.

[0045] In addition, refer to Figure 9 The stacking device in this embodiment may further include at least one second guide rail 1000, which extends along a second direction. The second mounting plate 600 can be mounted on the second guide rail 1000 by a slider, so that the second mounting plate 600 can slide relative to the second guide rail 1000 along the second direction.

[0046] For example, there can be two second guide rails 1000, which are located at opposite ends of the second mounting plate 600 along the first direction, thereby improving the support effect on the second mounting plate 600 and ensuring that the second mounting plate 600 remains stable during sliding.

[0047] Combination Figures 7 to 9 When the height of the blade 200 needs to be adjusted, the second drive device 710 can drive the cam 721 to rotate around the first axis. During the rotation, the cam 721 can drive the connecting rod 722 to rotate relative to the cam 721 around the second axis and relative to the second mounting plate 600 around the third axis. Since the connecting rod 722 is connected to the second mounting plate 600, during the rotation, the connecting rod 722 can counteract the rotational tendency of the second mounting plate 600, thus causing the second mounting plate 600 to move only along the second direction. Under the guidance of the second guide rail 1000, the second mounting plate 600 slides more smoothly along the second direction.

[0048] It is understood that in this embodiment, the vertical lifting and lowering of the pressure knife is achieved by using a cam linkage mechanism 720. The transmission part of the cam linkage mechanism 720 is realized by bearings. When the first guide rail 300 is inverted on the back of the first mounting plate 100, dust can be better prevented from accumulating on the first guide rail 300, thereby improving the dustproof effect.

[0049] As mentioned above, the first drive module 500 can be fixed to the second mounting plate 600, as an optional implementation scheme, such as... Figure 1 or Figure 9 As shown, a first support plate 800 can be provided, which can be fixedly connected to one of the two sides of the second mounting plate 600 along the first direction. The first driving device 540 and the first rotating structure are respectively provided on opposite sides of the first support plate 800 along the second direction. Furthermore, the active rotating structure 510 can also be located on the side of the first support plate 800 facing the blade 200, so that the first support plate 800 can also support the active rotating structure 510 and ensure that the active rotating structure 510 remains stable during rotation.

[0050] Additionally, refer to again Figure 1 A second support plate 900 may also be provided, which is parallel to the second mounting plate 600 and located on the side of the second mounting plate 600 opposite to the second guide rail 1000. The cam 721 and the second drive device 710 are respectively provided on opposite sides of the second support plate 900, so that the second drive device 710 can be fixed while the cam 721 is rotating.

[0051] To further improve the dustproof effect, combined with Figure 1 and Figure 10 The first mounting plate 100 has baffles 1100 on both opposite sides along a first direction, and the baffles 1100 extend in the direction from the first mounting plate 100 toward the first guide rail 300. Alternatively, a dustproof plate 1200 can be provided on the side of the first mounting plate 100 away from the second mounting plate 600, and the dustproof plate 1200 extends in the direction from the first mounting plate 100 toward the first guide rail 300. In this way, the first mounting plate 100, the second mounting plate 600, the two baffles 1100, and the dustproof plate 1200 can form five dustproof surfaces, thereby maximizing the dustproof effect and preventing dust from accumulating on the first guide rail 300.

[0052] The material of the 1200 dustproof plate can be, for example, stainless steel. Stainless steel has strong corrosion resistance and is not easily deformed. In a dusty production environment, it will not easily deform or be corroded, and can play a very good dustproof role.

[0053] It should be noted that in practical applications, either the baffle 1100 or the dustproof plate 1200 can be set, or both can be set. This embodiment does not limit this.

[0054] In some embodiments, the synchronous belt 530 may be made of rubber, for example, neoprene rubber, hydrogenated nitrile rubber, etc. Because rubber has wear-resistant properties, the lifespan of the synchronous belt 530 can be guaranteed during the operation of the laminating device, thereby reducing the frequency of maintenance. This helps to reduce production costs.

[0055] Obviously, those skilled in the art can make various modifications and variations to the embodiments of this utility model without departing from the spirit and scope of this utility model. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
