Description

Technical Field

[0001] The present application relates to the field of handling equipment, and in particular to a spacer mounting device. Background Art

[0002] When producing battery cell modules, spacers need to be pre-attached to the battery cells, and then multiple battery cells are stacked into a battery cell module, with adjacent battery cells adhered together by spacers.

[0003] In order to facilitate the storage and transportation of spacers, release films are affixed to both adhesive surfaces of the spacers to be mounted. Before mounting the spacers on the battery cells, the release films on the two adhesive surfaces of the spacers need to be torn off first. The current processing method is that the conveyor line first transports the battery cells to the mounting station, and then the spacers are picked up by the transport mechanism and taken to the film tearing station. The film tearing mechanism first tears off the release film on the lower surface of the spacer. Subsequently, the transport mechanism mounts the spacer on the battery cell at the mounting station. Subsequently, another film tearing mechanism tears off the release film on the upper surface of the spacer mounted on the battery cell, and the conveyor line finally transports the battery cells with completed mounting to the stacking station.

[0004] In the existing patch method, the conveying mechanism needs to pick up the spacers from the spacer material box, send the picked spacers to the film tearing station for film tearing, and then adhere the torn spacers to the battery cells. The conveying mechanism has too many processes. During its operation, other stations can only be in a state of shutdown and waiting, resulting in low production efficiency. Utility Model Content

[0005] In order to solve the above technical problems, the present application provides a spacer installation device, and its technical solution is as follows:

[0006] A spacer installation device includes a first transport mechanism, a second transport mechanism, a first film tearing mechanism, a second film tearing mechanism and a conveying mechanism, wherein:

[0007] The first transport mechanism and the second transport mechanism are arranged side by side;

[0008] The first film tearing mechanism is arranged above or below the first transport mechanism, and the second film tearing mechanism is arranged above or below the second transport mechanism;

[0009] The first transport mechanism is configured to suck a separator having first and second release films respectively applied to both sides thereof, and to drive the separator to rotate circumferentially around the center of the first transport mechanism, so that the separator passes through the first film tearing mechanism and the second transport mechanism in sequence, and the first film tearing mechanism is configured to tear off the first release film on the separator;

[0010] The second transport mechanism is configured to suck the first surface of the separator after the first release film is torn off, and drive the separator to rotate circumferentially around the center of the second transport mechanism, so that the separator passes through the second film-tearing mechanism and the conveying mechanism in sequence, and the second film-tearing mechanism is configured to tear off the second release film on the separator;

[0011] The transport mechanism is configured to suck the second side of the separator from which the second release film is torn off, and to attach the first side of the separator to the battery cell.

[0012] Through the coordinated transport of the first and second transport mechanisms, the first and second tearing mechanisms can simultaneously tear the film from the separator. Furthermore, while the first and second tearing mechanisms are tearing the film, the transport mechanism can transport the torn separator and attach it to the battery cell. In other words, with the separator installation device of the present application, multiple steps in the separator installation process can be performed simultaneously. While one step is being performed, the other steps do not need to wait, ultimately improving the production efficiency of the battery cell module.

[0013] In some embodiments, the first transport mechanism includes a first mounting seat, a first driving unit, a first rotating bracket and at least three first adsorption components; the first driving unit is arranged on the first mounting seat; the first rotating bracket is connected to the movable part of the first driving unit, and each first adsorption component is arranged at equal intervals in the circumference of the first rotating bracket; the first driving unit is configured to drive the first rotating bracket to rotate around its own central axis to drive each first adsorption component to rotate, and a first receiving station, a first film tearing station and a pushing station are sequentially provided on the rotation path of the first adsorption component; when the first adsorption component rotates to the first receiving station, the first adsorption component is configured to receive a separator covered with a first release film and a second release film; when the first adsorption component rotates to the first film tearing station, the first adsorption component is configured to cooperate with the first film tearing mechanism to tear off the first release film on the separator; when the first adsorption component rotates to the pushing station, the first adsorption component is configured to push the separator with the first release film torn off to the second transport mechanism; when the first first adsorption component is located at the first receiving station, the second first adsorption component is located at the first film tearing station, and the third first adsorption component is located at the pushing station.

[0014] By setting up the first transport mechanism, it is achieved that at the same time, there is a first adsorption component at the first receiving station, the first film tearing station and the pushing station. That is to say, the three processing stations can simultaneously perform separator receiving, film tearing and pushing operations, thereby speeding up the work rhythm and improving work efficiency.

[0015] In some embodiments, the first driving portion includes a first rotating driving member and a first rotating shaft, wherein: the first rotating shaft is rotatably mounted on a first mounting seat along its own axis, and the first rotating bracket is fixedly sleeved on the first rotating shaft; the first rotating driving member is mounted on the first mounting seat and is transmission-connected to the first rotating shaft, and the first rotating driving member is configured to drive the first rotating shaft to rotate, so as to drive the first rotating bracket to rotate around the axis of the first rotating shaft.

[0016] A method for implementing a first driving portion with a simple structure is provided, which drives a first rotating shaft to rotate through a first rotating driving member, thereby driving a first rotating bracket installed on the first rotating shaft to rotate.

[0017] In some embodiments, the first rotating bracket includes a first mounting plate and at least three first sliding mounting seats, wherein: the first mounting plate is fixedly sleeved on the first rotating shaft; the first sliding mounting seats are slidably connected to the first mounting plate and are arranged one-to-one with the first adsorption components, and the first sliding mounting seats are configured to be able to slide radially toward or away from the first rotating shaft, and each first adsorption component is connected to the corresponding first sliding mounting seat; the first transport mechanism also includes a pushing drive unit provided on the first mounting seat, and the pushing drive unit is configured to drive the first adsorption component located at the pushing station to slide in a direction away from the first rotating shaft, so as to drive the first adsorption component to push the spacer for completing the tearing of the first release film to the second transport mechanism.

[0018] By arranging the first adsorption assembly on the first sliding mounting seat and arranging a pushing drive unit on the first mounting seat, when the first adsorption assembly carries the separator from which the first release film has been torn off and rotates to the pushing station, the pushing drive unit can push the first adsorption assembly toward the second transport mechanism via the first sliding mounting seat, thereby pushing the separator from which the first release film has been torn off onto the second transport mechanism.

[0019] In some embodiments, the first transport mechanism also includes a limit plate, which is fixedly mounted on the first mounting seat in the vertical direction, and a circular limit groove is provided on the limit plate, and a notch is provided on the limit groove that opens toward the pushing station; a limit wheel is provided on the first sliding mounting seat, and the limit wheel is located in the limit groove, and when the first sliding mounting seat rotates circumferentially with the first mounting plate, the limit wheel slides along the limit groove; when the first adsorption component rotates to the pushing station, the limit wheel on the first sliding mounting seat corresponding to the first adsorption component is located at the notch, and when the pushing drive part drives the first sliding mounting seat to slide away from the first rotating axis, the limit wheel slides out of the limit groove through the notch.

[0020] By providing a limiting plate with a limiting groove and a limiting wheel on the first sliding mounting seat, it is possible to achieve that when the first sliding mounting seat rotates circumferentially with the first mounting plate, the limiting wheel on it is limited within the limiting groove, thereby achieving rotational guidance of the first sliding mounting seat and preventing the first sliding mounting seat from radially sliding during rotation, which would cause radial movement of the first adsorption assembly. When the first sliding mounting seat rotates to the pushing position, the notch in the limiting groove releases the limiting wheel, allowing the first sliding mounting seat to slide toward the second transport mechanism under the push of the pushing drive unit, ultimately allowing the first adsorption assembly to push the separator, from which the first release film has been removed, onto the second transport mechanism.

[0021] In some embodiments, the pushing drive part includes a pushing drive member and a pushing block, wherein: the pushing block is located at the notch of the limiting groove, and an arc groove is provided on the pushing block for the limiting wheel to pass through, and the arc groove of the pushing block cooperates with the limiting groove to form a circular groove body; the pushing drive member is configured to drive the pushing block to slide radially away from the notch, so as to drive the first adsorption component located at the pushing station to push the spacer that has completed the tearing of the first release film to the second transport mechanism.

[0022] When the first sliding mount rotates to the pushing position, the limiting wheel on the first sliding mount enters the arcuate groove of the push block through the notch in the limiting groove, thereby achieving positioning of the limiting wheel. After the first adsorption assembly pushes the spacer to the second transport mechanism, the driving member drives the push block to slide radially toward the notch to reset, so that the arcuate groove of the push block and the limiting groove once again form a circular groove. In this way, when the first sliding mount continues to rotate, the limiting wheel on the first sliding mount can smoothly slide from the arcuate groove of the push block back into the limiting groove.

[0023] In some embodiments, the first transport mechanism includes four first adsorption components, and the four first adsorption components are evenly arranged on the first rotating bracket along the circumference; an idle station located between the pushing station and the first receiving station is also provided on the rotation path of the first adsorption component, and the first receiving station, the first film tearing station, the pushing station and the idle station are evenly arranged on the rotation path of the first adsorption component along the circumference; when one of the first adsorption components is located at the first receiving station, there is a first adsorption component at the first film tearing station, the pushing station and the idle station.

[0024] With this arrangement, the second drive unit drives the second rotating bracket to rotate 90° around its central axis each time, causing each second adsorption assembly to sequentially pass through the second receiving station, the second film tearing station, the output station, and the idle station. Furthermore, a second adsorption assembly is present at each of the second receiving station, the second film tearing station, and the output station at the same time. In other words, the three processing stations can simultaneously perform the receiving, film tearing, and output operations on the three separators, thereby speeding up the work cycle and improving work efficiency.

[0025] In some embodiments, the second transport mechanism includes a second mounting seat, a second driving unit, a second rotating bracket and a plurality of second adsorption components, the number of the second adsorption components is the same as the number of the first adsorption components, and the structures of the first adsorption components and the second adsorption components are the same; the second driving unit is arranged on the second mounting seat; the second rotating bracket is connected to the movable part of the second driving unit, and each second adsorption component is arranged at equal intervals in the circumference of the second rotating bracket; the second driving unit is configured to drive the second rotating bracket to rotate around its own central axis to drive each second adsorption component to rotate, and a second receiving station, a second film tearing station and an output station are sequentially arranged on the rotation path of the second adsorption component, wherein the second receiving station is opposite to the pushing station; when the second adsorption component rotates to the second receiving station, the second adsorption component is configured to receive the diaphragm with the first release film torn off pushed by the first adsorption component at the pushing station; when the second adsorption component rotates to the second film tearing station, the second adsorption component is configured to cooperate with the second film tearing mechanism to tear off the second release film; when the second adsorption component rotates to the output station, the conveying mechanism sucks the diaphragm with the second release film torn off from the second adsorption component.

[0026] By setting up the second transport mechanism, each second adsorption component can rotate through the second receiving station, the second film tearing station and the output station in sequence, so that the second adsorption component can complete the separator receiving, film tearing and output operations in sequence and continuously.

[0027] In some embodiments, the second transport mechanism includes four second adsorption components, which are evenly arranged circumferentially on the second rotating bracket. When one of the second adsorption components is located at the second receiving station, there is a second adsorption component at the second film tearing station and the output station.

[0028] At the same time, there is a second adsorption component at the second receiving station, the second film tearing station and the output station. That is to say, the three processing stations can simultaneously implement the separator receiving, film tearing and output operations, thereby speeding up the work rhythm and improving work efficiency.

[0029] In some embodiments, the first adsorption component includes a substrate, multiple suction cups and an anti-sticking member. The substrate is fixed on a first rotating bracket. The multiple suction cups are evenly arranged on the substrate. The suction cups suck the spacer through negative pressure. The anti-sticking member is attached to the side of the substrate with the suction cups. An opening is opened on the anti-sticking member to avoid the suction cups, and the adsorption end of the suction cup is located in the opening of the anti-sticking member.

[0030] The first suction assembly uses the negative pressure of the suction cup to attach the spacer to the substrate. Because the substrate is provided with a release member, and the suction end of the suction cup is located within the opening of the release member, it does not contact the spacer. Therefore, during the process of attaching the completed spacer, the first suction assembly will not adhere to the spacer.

[0031] In some embodiments, the conveying mechanism includes a second moving part and a third adsorption component, the third adsorption component is connected to the movable part of the second moving part, and the structure of the third adsorption component is the same as that of the first adsorption component; the second moving part is configured to drive the third adsorption component to move, so as to drive the third adsorption component to absorb the separator after the second release film is torn off from the second transport mechanism, and to attach the separator to the battery cell.

[0032] A simple transport mechanism is provided. A second moving portion drives a third suction assembly to move, allowing the third suction assembly to pick up a separator from the second transport mechanism, after the second release film has been removed, and then attach the separator to the battery cell. Furthermore, because the third suction assembly has the same structure as the first suction assembly, adhesion between the third suction assembly and the separator is avoided.

[0046] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0047] like Figure 1 As shown, the spacer installation device in the embodiment of the present application includes a first transport mechanism 1, a second transport mechanism 2, a first film tearing mechanism 3, a second film tearing mechanism 4 and a conveying mechanism 5, wherein:

[0048] The first transport mechanism 1 and the second transport mechanism 2 are arranged side by side.

[0049] The first film tearing mechanism 3 is arranged below the first transport mechanism 1, and the second film tearing mechanism 4 is arranged below the second transport mechanism 2. Of course, the first film tearing mechanism 3 can also be arranged above the first transport mechanism 1, and the second film tearing mechanism 4 can be arranged above the second transport mechanism 2.

[0050] The first transport mechanism 1 is configured to suck the separator with the first release film and the second release film respectively on both sides, and drive the separator to rotate circumferentially around the center of the first transport mechanism 1, so that the separator passes through the first film tearing mechanism 3 and the second transport mechanism 2 in sequence. The first film tearing mechanism 3 is configured to tear off the first release film on the separator, thereby exposing the first sticky side of the separator.

[0051] The second transport mechanism 2 is configured to suck the first surface of the separator after the first release film is torn off, and to drive the separator to rotate circumferentially around the center of the second transport mechanism 2, so that the separator passes through the second film tearing mechanism 4 and the conveying mechanism 5 in sequence. The second film tearing mechanism 4 is configured to tear off the second release film on the separator, thereby exposing the second sticky surface of the separator.

[0052] The transport mechanism 5 is configured to suck the second side of the separator from which the second release film is torn off, and to attach the first side of the separator to the battery cell 100 .

[0053] It can be seen that through the coordinated transportation of the first transport mechanism 1 and the second transport mechanism 2, the first film tearing mechanism 3 and the second film tearing mechanism 4 can synchronously perform the film tearing operation on the separator, that is, the first film tearing mechanism 3 tears off the first release film of one separator while the second film tearing mechanism 3 tears off the second release film of another separator.

[0054] Furthermore, while the first and second film-tearing mechanisms 3 and 4 are performing the film-tearing operation, the transport mechanism 5 can transport the torn spacer and attach it to the battery cell 100. In other words, with the spacer installation device of the present application, multiple processes during the spacer installation process can be performed simultaneously. While one process is being performed, the other processes do not need to wait, ultimately improving the production efficiency of the battery cell module.

[0055] like Figure 2 As shown, the first transport mechanism 1 optionally includes a first mounting base 11, a first drive unit 12, a first rotating bracket 13, and at least three first adsorption assemblies 14. The first drive unit 12 is disposed on the first mounting base 11. The first rotating bracket 13 is connected to the movable component of the first drive unit 12, and the first adsorption assemblies 14 are equidistantly arranged around the circumference of the first rotating bracket 13.

[0056] The first driving part 12 is configured to drive the first rotating bracket 13 to rotate around its own central axis to drive each first adsorption component 14 to rotate. The first receiving station, the first film tearing station and the pushing station are sequentially provided on the rotation path of the first adsorption component 14.

[0057] When the first adsorption assembly 14 rotates to the first receiving station, it is configured to receive a separator coated with a first release film and a second release film. When the first adsorption assembly 14 rotates to the first film tearing station, it is configured to cooperate with the first film tearing mechanism 3 to tear off the first release film from the separator, thereby exposing the separator's first adhesive surface. When the first adsorption assembly 14 rotates to the pushing station, it is configured to push the separator, with the first release film removed, onto the second transport mechanism 5.

[0058] In particular, when the first first adsorption component 14 is located at the first receiving station, the second first adsorption component 14 is located at the first film tearing station, and the third first adsorption component 14 is located at the pushing station.

[0059] By configuring the first transport mechanism, each first adsorption assembly 14 can rotate sequentially through the first receiving station, the first film tearing station, and the pushing station, thereby enabling the first adsorption assembly 14 to sequentially and continuously complete the separator receiving, film tearing, and separator pushing operations. Furthermore, after the first rotating bracket 13 completes one rotation, a first adsorption assembly 14 is present at each of the first receiving station, the first film tearing station, and the pushing station. In other words, the three processing stations can simultaneously perform separator receiving, film tearing, and pushing operations, further accelerating work pace and improving work efficiency.

[0060] In order to improve the installation stability of the first adsorption component 14 , optionally, the first transport mechanism 1 includes two first rotating brackets 13 arranged side by side, and both ends of the first adsorption component 14 are respectively connected to one of the first rotating brackets 13 .

[0061] Figure 2 In the illustrated embodiment, the first transport mechanism 1 includes four first adsorption assemblies 14, which are evenly arranged along the circumference of the first rotating bracket 13. An idle station is also provided on the rotation path of the first adsorption assembly 14, located between the pushing station and the first receiving station. The first receiving station, the first film tearing station, the pushing station, and the idle station are evenly arranged along the circumference of the rotation path of the first adsorption assembly 14. When one of the first adsorption assemblies 14 is located at the first receiving station, there is a first adsorption assembly 14 at each of the first film tearing station, the pushing station, and the idle station.

[0062] With this arrangement, the first driving unit 12 drives the first rotating bracket 13 to rotate 90° around its own central axis in each step, so as to drive each first adsorption component 14 to pass through the first receiving station, the first film tearing station, the pushing station and the idling station in sequence. Of course, in other embodiments, three, five or other numbers of first adsorption components 14 may also be provided. For example, when three first adsorption components 14 are provided, an idling station does not need to be provided on the rotation path of the first adsorption component 14. When five first adsorption components 14 are provided, two idling stations need to be provided on the rotation path of the first adsorption component 14.

[0063] Optionally, the first driving unit 12 includes a first rotating drive member 121 and a first rotating shaft 122, wherein the first rotating shaft 122 is rotatably mounted on the first mounting seat 11 along its own axis, and the first rotating bracket 13 is fixedly sleeved on the first rotating shaft 122. The first rotating drive member 121 is mounted on the first mounting seat 11 and is in transmission connection with the first rotating shaft 122. The first rotating drive member 121 is configured to drive the first rotating shaft 122 to rotate, thereby driving the first rotating bracket 13 to rotate about the axis of the first rotating shaft 122.

[0064] like Figures 2 to 4As shown, optionally, the first transport mechanism 1 further includes a limiting plate 15, which is fixedly mounted on the first mounting seat 11 in the vertical direction. The limiting plate 15 is provided with a circular limiting groove 151, and the limiting groove 151 is provided with a notch 153 opening toward the pushing station. The first sliding mounting seat 132 is provided with a limiting wheel 152, which is located in the limiting groove 151. When the first sliding mounting seat 132 rotates circumferentially with the first mounting plate 131, the limiting wheel 152 slides along the limiting groove 151. When the first adsorption component 14 rotates to the pushing station, the limiting wheel 152 on the first sliding mounting seat 132 corresponding to the first adsorption component 14 is located at the notch 153. At this time, when the pushing drive unit 16 drives the first sliding mounting seat 132 to slide away from the first rotating shaft 122, the limiting wheel 152 can slide out of the limiting groove 551 through the notch 153.

[0065] As can be seen, by providing the limiting plate 15 with the limiting groove 151 and the limiting wheel 152 on the first sliding mounting seat 132, it can be achieved that when the first sliding mounting seat 132 rotates circumferentially with the first mounting plate 131, the limiting wheel 152 thereon is limited in the limiting groove 151, thereby achieving rotation guidance for the first sliding mounting seat 132 and preventing the first sliding mounting seat 132 from radially sliding during the rotation process, which would cause the first adsorption assembly 14 to move radially.

[0066] When the first sliding mounting seat 132 rotates to the pushing position, the notch 153 on the limiting groove 151 can release the limiting effect of the limiting groove 151 on the limiting wheel 152, so that the first sliding mounting seat 132 slides toward the second transport mechanism 2 under the push of the pushing drive part 16, and finally the first adsorption component 14 pushes the spacer with the first release film torn off to the second transport mechanism 2.

[0067] like Figure 3 and Figure 4 As shown, the push drive unit 16 optionally includes a push drive member 161 and a push block 162. The push block 162 is located at the notch 153 of the limiting groove 151. The push block 162 has an arcuate groove for the limiting wheel 152 to pass through. The arcuate groove of the push block 162 cooperates with the limiting groove 151 to form a circular groove. The push drive member 161 is configured to drive the push block 162 to slide radially outward away from the notch 153, thereby driving the first adsorption assembly 14 at the pushing station to push the separator, from which the first release film has been removed, to the second transport mechanism 2.

[0068] Specifically, when the first sliding mounting seat 132 rotates to the pushing position, the limiting wheel 152 on the first sliding mounting seat 132 enters the arc groove of the push block 162 through the notch 153 on the limiting groove 151, and then the driving member 161 drives the push block 162 to slide radially away from the notch 153 to push the first sliding mounting seat 132 to slide toward the second transport mechanism 2, and finally the first adsorption component 14 pushes the spacer that completes the tearing of the first release film to the second transport mechanism 2.

[0069] After the first adsorption assembly 14 pushes the spacer to the second transport mechanism 2, the driving member 161 drives the push block 162 to slide radially toward the notch 153 and return to its original position, so that the arcuate groove of the push block 162 and the limiting groove 151 once again form a circular groove. In this way, when the first sliding mounting seat 132 continues to rotate, the limiting wheel 152 on the first sliding mounting seat 132 can smoothly slide from the arcuate groove of the push block 162 back into the limiting groove 151.

[0070] like Figure 2 As shown, optionally, the first adsorption component 14 includes a substrate 141, a plurality of suction cups 142 and an anti-sticking member, the substrate 141 is fixed on the first rotating bracket 131, and the plurality of suction cups 142 are evenly arranged on the substrate 141, the suction cups 142 suck the spacer through negative pressure, and the anti-sticking member is attached to the side of the substrate with the suction cup 142, and an opening is opened on the anti-sticking member to avoid the suction cup 142, and the adsorption end of the suction cup 142 is located in the opening of the anti-sticking member.

[0071] The first suction assembly 14 uses the negative pressure of the suction cup 142 to suck the separator onto the substrate 141. Because the substrate 141 is provided with a release member, and the suction end of the suction cup 142 is located within the opening of the release member, it does not contact the separator. Therefore, when sucking the separator, the first suction assembly 14 does not adhere to the separator.

[0072] The structure of the second transport mechanism 2 is essentially the same as that of the first transport mechanism 1, comprising a second mounting base, a second drive unit, a second rotating bracket, and a plurality of second adsorption assemblies. The number of second adsorption assemblies is the same as that of the first adsorption assemblies, and the second adsorption assemblies have the same structure as the first adsorption assembly 14. The second drive unit is mounted on the second mounting base. The second rotating bracket is connected to the movable component of the second drive unit, and the second adsorption assemblies are evenly spaced around the circumference of the second rotating bracket.

[0073] The second driving unit is configured to drive the second rotating bracket to rotate around its own central axis to drive each second adsorption component to rotate. The second receiving station, the second film tearing station and the output station are sequentially arranged on the rotation path of the second adsorption component, wherein the second receiving station is opposite to the pushing station.

[0074] When the second adsorption assembly rotates to the second receiving station, the second adsorption assembly is configured to receive the separator with the first release film torn off pushed by the first adsorption assembly 14 located at the pushing station.

[0075] When the second adsorption assembly rotates to the second film-tearing station, the second adsorption assembly is configured to cooperate with the second film-tearing mechanism 4 to tear off the second release film to expose the second adhesive surface.

[0076] When the second adsorption assembly rotates to the output station, the transport mechanism 5 absorbs the separator of the second release film from the second adsorption assembly.

[0077] By configuring the second transport mechanism, each second adsorption assembly can rotate sequentially through the second receiving station, the second film tearing station, and the output station, thereby enabling the second adsorption assembly to sequentially complete the separator receiving, film tearing, and output operations. Since the second adsorption assembly has the same structure as the first adsorption assembly, the separators will not stick when it is adsorbed.

[0078] As described above, when the first transport mechanism 1 includes four first adsorption components 14, the second transport mechanism 2 also includes four second adsorption components, which are evenly arranged on the second rotating bracket along the circumferential direction. When one of the second adsorption components is located at the second receiving station, there is a second adsorption component at the second film tearing station and the output station.

[0079] With this arrangement, the second drive unit rotates the second rotating bracket 90° around its central axis each time, causing each second suction assembly to sequentially pass through the second receiving station, the second film tearing station, the output station, and the idle station. At the same time, a second suction assembly is present at each of the second receiving station, the second film tearing station, and the output station. This means that the three processing stations can simultaneously perform the receiving, film tearing, and output operations on the three separators, thereby speeding up work and improving efficiency.

[0080] In the embodiment of the present application, the transport pace of the first transport mechanism 1 and the second transport mechanism 2 is kept consistent, that is, when the first adsorption component of the first transport mechanism 1 carrying the separator with the first release film torn off rotates to the pushing station, a second adsorption component of the second transport mechanism 2 rotates synchronously to the second receiving station.

[0081] Optionally, the second film-tearing mechanism 4 has the same structure as the first film-tearing mechanism 3. Taking the first film-tearing mechanism 3 as an example, it includes a first movable portion 31 and a clamping jaw assembly 32, wherein the clamping jaw assembly 32 is connected to the movable component of the first movable portion 31. When the septum rotates to the first film-tearing station under the drive of the first adsorption assembly 14, the first movable portion drives the clamping jaw assembly toward the septum so that the clamping jaw assembly contacts and clamps the end of the first release film on the septum. Subsequently, the first movable portion drives the clamping jaw assembly away from the septum, thereby tearing the clamped first release film from the septum.

[0082] The first moving portion can be implemented as any existing moving mechanism capable of driving the gripper assembly 32 to translate and elevate. For example, the first moving portion may include an integrated translation module and an elevation module, wherein the translation module is used to drive the gripper assembly 32 to translate horizontally, and the elevation module is used to drive the gripper assembly 32 to elevate. The first moving portion may also be implemented as a multi-axis robotic arm, with the gripper assembly 32 connected to the end of the multi-axis robotic arm.

[0083] like Figure 5 As shown, the transport mechanism 5 includes a second moving portion 51 and a third suction assembly 52. ​​The third suction assembly 52 is connected to the movable part of the second moving portion 51. The second moving portion 51 is configured to drive the third suction assembly 52 to move, thereby causing the third suction assembly 52 to absorb the separator from the second transport mechanism 2 after the second release film is removed, and then attach the separator to the battery cell.

[0084] Similarly, the second moving part 51 can adopt various existing moving mechanisms that can drive the third adsorption component 52 to move horizontally and vertically. For example, the second moving part includes an integrated translation module and a lifting module, or the second moving part is also a multi-axis robot arm.

[0085] In order to prevent the third adsorption component 52 from adhering to the spacer, the third adsorption component 52 may have the same structure as the first adsorption component in the above embodiment.
