Description

Technical Field

[0001] The embodiments of the present utility model relate to the technical field of battery manufacturing, and particularly to the technical field of lithium-ion battery cell manufacturing. Specifically, the present application relates to a laminator. Background Art

[0002] During the battery manufacturing process, the preparation method of the battery cell mainly adopts a "Z"-shaped laminating scheme. Among them, the separator needs to be transported by a transport mechanism and accurately guided to the laminating platform by a film covering mechanism to complete the laying of the separator. And the laid separator forms a "Z"-shaped fold on the laminating platform and cooperates with the actions of the laminating table and the battery electrode sheets to alternately stack the positive battery sheets and the negative battery sheets between two layers of separators to form a battery laminate. Therefore, the equipment for realizing the laminating operation involves many structural components. However, at present, the layout of the structural components of the laminating equipment is not compact, and the area occupied by the laminating operation is relatively large. Summary of the Utility Model

[0003] The present application aims to solve at least one of the technical problems existing in the prior art. For this purpose, the present utility model provides a laminator, in which the layout of the structural components is compact and the space is fully utilized.

[0004] The solution of the example of the present application is implemented through the following content.

[0005] The example of the present application provides a laminator, which includes a base, a transport component, a film covering component, a laminating table component, a gluing component, a battery cell handling mechanism, a track and a carrier mechanism, wherein:

[0006] The base extends along a first direction. The film covering component is arranged on the side wall of the base. The transport component is arranged on the base and is used for transporting the separator and supplying it to the film covering component. The film covering component is used for laying the separator on the laminating table component;

[0007] The laminating table component is arranged adjacent to the side wall of the base. The laminating table component is used for receiving the battery electrode sheets and the separator guided to the laminating table component for laying. At least one of the film covering component and the laminating table component can be driven to reciprocate along the first direction. The film covering component and the laminating table component cooperate with each other to realize the stacking of the battery electrode sheets and the separator to form a battery cell;

[0008] The gluing component is arranged on the base. The battery cell handling mechanism is arranged on one side of the laminating table component away from the side wall of the base and is used for transporting the battery cell to the gluing component. The gluing component is used for gluing on the outer side of the battery cell to fix the battery cell;

[0009] The track is installed on the base. The first end of the track is set as the discharging end, and the second end of the track is adjacent to the glue - applying assembly. The carrying mechanism is slidably arranged on the track. The carrying mechanism is used to receive the completed - glued battery cells carried away from the glue - applying assembly by the battery cell handling mechanism, and the carrying mechanism is also used to convey the battery cells along the track to the discharging end.

[0010] For the laminator provided in this application, a stacking table assembly is arranged on one side of the extended base, and a guide rail is arranged on the side wall of the base. A film - covering assembly is arranged on the guide rail to cooperate with the stacking table assembly to perform lamination. The glue - applying assembly is arranged on the base, and the track of the carrying mechanism extends to the vicinity of the glue - applying assembly, thereby increasing the compactness of the space layout, making full use of the existing space, and saving the occupied working surface.

[0011] In one example, the glue - applying assembly is arranged near the first end of the base. The laminator further includes a vertical plate, which is arranged on the base and near the second end of the base, and the vertical plate has an installation surface parallel to the side wall of the base, and the transmission assembly is installed on the installation surface.

[0012] The vertical plate and the glue - applying assembly are distributed at both ends of the base, and the transmission assembly is arranged on the vertical plate, thereby raising the installation height of the transmission assembly and improving the space utilization.

[0013] In one example, the laminator further includes a negative - electrode sheet feeding mechanism, a negative - electrode sheet deviation - correcting mechanism, a positive - electrode sheet deviation - correcting mechanism, and a positive - electrode sheet feeding mechanism, where:

[0014] The negative - electrode sheet feeding mechanism, the negative - electrode sheet deviation - correcting mechanism, the stacking table assembly, the positive - electrode sheet deviation - correcting mechanism, and the positive - electrode sheet feeding mechanism are arranged at intervals in sequence along the first direction;

[0015] Above the negative - electrode sheet feeding mechanism and the negative - electrode sheet deviation - correcting mechanism, there is a negative - electrode sheet handling assembly. Above the positive - electrode sheet feeding mechanism and the positive - electrode sheet deviation - correcting mechanism, there is a positive - electrode sheet handling assembly. The negative - electrode sheet handling assembly is used to convey the negative - electrode battery sheets from the negative - electrode sheet feeding mechanism to the negative - electrode sheet deviation - correcting mechanism, and convey the negatively - electrode battery sheets with the attitude corrected from the negative - electrode sheet deviation - correcting mechanism to the stacking table assembly. The positive - electrode sheet handling assembly is used to convey the positive - electrode battery sheets from the positive - electrode sheet feeding mechanism to the positive - electrode sheet deviation - correcting mechanism, and convey the positively - electrode battery sheets with the attitude corrected from the positive - electrode sheet deviation - correcting mechanism to the stacking table assembly.

[0016] The negative - electrode sheet feeding mechanism and the negative - electrode sheet deviation - correcting mechanism are on one side of the stacking table assembly, and the positive - electrode sheet deviation - correcting mechanism and the positive - electrode sheet feeding mechanism are on the other side of the stacking table assembly. Moreover, the negative - electrode sheet feeding mechanism, the negative - electrode sheet deviation - correcting mechanism, the stacking table assembly, the positive - electrode sheet deviation - correcting mechanism, and the positive - electrode sheet feeding mechanism are all on the same side of the base and are arranged at intervals in sequence along the first direction. Compared with the arrangement method staggered in two dimensions, this arrangement method is relatively one - dimensional, which helps to improve the space utilization.

[0017] In one example, a guide rail extending in a first direction is provided on the side wall of the base. Both the positive electrode sheet handling assembly and the negative electrode sheet handling assembly are provided on the guide rail. The negative electrode sheet handling assembly is on the side close to the negative electrode sheet feeding mechanism and the negative electrode sheet alignment mechanism, and the positive electrode sheet handling assembly is on the side close to the positive electrode sheet feeding mechanism and the positive electrode sheet alignment mechanism.

[0018] The positive electrode sheet handling assembly and the negative electrode sheet handling assembly share the guide rail extending in the first direction, saving the redundant setting of similar components and space occupation.

[0019] In one example, the negative electrode sheet handling assembly includes a first negative electrode sheet handling mechanism and a second negative electrode sheet handling mechanism both slidably provided on the guide rail and drivable to reciprocate. The first negative electrode sheet handling mechanism is used to transport the negative electrode cells provided by the negative electrode sheet feeding mechanism to the negative electrode sheet alignment mechanism to achieve attitude alignment, and the second negative electrode sheet handling mechanism is used to transport the negative electrode cells on the negative electrode sheet alignment table assembly to the stacking table assembly to achieve stacking; and / or,

[0020] The positive electrode sheet handling assembly includes a first positive electrode sheet handling mechanism and a second positive electrode sheet handling mechanism both slidably provided on the guide rail and drivable to reciprocate. The first positive electrode sheet handling mechanism is used to transport the positive electrode cells provided by the positive electrode sheet feeding mechanism to the positive electrode sheet alignment mechanism to achieve attitude alignment, and the second positive electrode sheet handling mechanism is used to transport the positive electrode cells on the positive electrode sheet alignment table assembly to the stacking table assembly to achieve stacking.

[0021] By providing the negative electrode sheet alignment mechanism and the positive electrode sheet alignment table mechanism to correct the attitude of the battery electrode sheets and then placing them on the separator, it helps to improve the stacking quality of the battery cells. In addition, the first negative electrode sheet handling mechanism and the second negative electrode sheet handling mechanism facilitate the synchronous handling from the negative electrode sheet feeding mechanism to the negative electrode sheet alignment mechanism and from the negative electrode sheet alignment mechanism to the stacking table assembly. The first positive electrode sheet handling mechanism and the second positive electrode sheet handling mechanism facilitate the synchronous handling from the positive electrode sheet feeding mechanism to the positive electrode sheet alignment mechanism and from the positive electrode sheet alignment mechanism to the stacking table assembly, and the way of being slidably provided on the guide rail saves the redundant setting of similar components and space occupation.

[0022] In one example, the battery cell handling mechanism includes:

[0023] A lateral translation module, provided on the side of the stacking table assembly away from the base, opposite to the adhesive application assembly, and extending in the first direction;

[0024] A lifting module, provided at the driving end of the lateral translation module to reciprocate along the first direction; and,

[0025] The picking part is arranged at the driving end of the lifting module to realize the height adjustment relative to the platform. The picking part transports the battery cells formed by stacking from the stacking table assembly to the gluing assembly and transports the battery cells completed with gluing from the gluing assembly to the carrying mechanism under the cooperation of the transverse movement module and the lifting module.

[0026] The battery cell handling mechanism is arranged opposite to the base and the gluing assembly. The distance for the battery cell handling mechanism to move to the stacking table assembly to pick up the battery cells is short, and the path of the battery cells from the stacking table assembly to the gluing assembly is also short. Therefore, it helps to reduce the moving distance of the battery cell handling.

[0027] In one example, when the height of the picking part is flush with that of the battery cell, it can move along the first direction to move the battery cell away from the stacking table assembly.

[0028] The action of the picking part along the first direction realizes the picking of the battery cell, making full use of the occupied space, and having the advantage of saving space occupation compared with picking actions perpendicular to the first direction in the same plane.

[0029] In one example, the first end of the track is located below the base, and the track is inclined and arranged on the base.

[0030] The first end of the track is the discharging end, and the setting lower than the base is convenient for manual collection of the battery cells.

[0031] In one example, when the height of the picking part is flush with the height of the gluing operation space inside the gluing assembly, it can move along the first direction to insert the battery cell into the gluing operation space.

[0032] The action along the first direction realizes the insertion of the battery cell into the gluing operation space, making full use of the occupied space.

[0033] In one example, the gluing assembly is fixedly connected to the base, and at least part of the gluing assembly deviates to one side of the stacking table assembly and is suspended.

[0034] The setting method of deviating to one side of the stacking table assembly and being suspended helps to reduce the movement of the battery cell handling mechanism. Description of the Drawings

[0046] Next, the technical solutions in the embodiments of the present disclosure will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present disclosure.

[0047] See Figures 1 to 5 As shown, an embodiment of the present application provides a laminator, which includes a base 100, a transmission assembly 200, a film - covering assembly 300, a stacking table assembly 400, a glue - applying assembly 500, a battery cell handling mechanism 600, a track 701, and a carrying mechanism 700, wherein:

[0048] The base 100 extends along a first direction. Specifically, in implementation, the base 100 can be a long beam made of marble, which has a length along the first direction and a thickness (or width) perpendicular to the first direction in the horizontal plane; the transmission assembly 200 is arranged on the base 100, and the transmission assembly 200 is used to transmit the diaphragm released from the diaphragm coil and supply it to the film - covering assembly 300; the film - covering assembly 300 is arranged on the side wall of the base 100, and the film - covering assembly 300 is used to guide the diaphragm to the stacking table assembly 400 for laying.

[0049] The stacked table assembly 400 is disposed adjacent to the sidewall of the base 100. The stacked table assembly 400 is used to receive the battery electrode sheet and the separator that is guided by the film covering assembly 300 and repeatedly folded and laid on the stacked table assembly 400. At least one of the film covering assembly 300 and the stacked table assembly 400 is drivable to reciprocate in the first direction. The film covering assembly 300 and the stacked table assembly 400 cooperate with each other to stack the battery electrode sheet and the separator to form an electric core. In the previous description, the "adjacent" setting method means that the spatial position of the stacked table assembly 400 is set close to and adjacent to the sidewall of the base 100, so that the related actions of the stacked table assembly 400 and the film covering assembly 300 for the lamination operation are more stable, and the cooperation is closer, smoother and more efficient.

[0050] The glue pasting assembly 500 is disposed on the base 100 so as to be arranged in a higher space by means of the base 100, thereby avoiding excessive structures occupying the low-height space; the electric core handling mechanism 600 and the base 100 are respectively disposed on both sides of the stacked table assembly 400 so that the electric core handling mechanism 600 is opposite to the base 100, so that the electric core handling mechanism 600 is relatively far from the sidewall of the base 100. The aforementioned reciprocating sliding in the first direction is performed in the space between the electric core handling mechanism 600 and the base 100. The lamination to form the electric core is achieved based on the action cooperation of the film covering assembly 300 and the stacked table assembly 400. The electric core handling mechanism 600 is used to transport the electric core to the glue pasting assembly 500. The glue pasting assembly 500 is used to paste glue on the outside of the electric core. After the glue pasting is completed, the electric core is fixed.

[0051] The track 701 is installed on the base 100. The first end of the track 701 is set as the discharging end for discharging the electric core after the glue pasting is completed. The second end of the track 701 is adjacent to the glue pasting assembly 500. The carrier mechanism 700 is slidably disposed on the track 701. The carrier mechanism 700 is used to receive the glued electric core carried away from the glue pasting assembly 500 by the electric core handling mechanism 600. The carrier mechanism 700 is also used to transport the electric core along the track 701 to the discharging end. It should be noted that the setting method that the second end of the track 701 is adjacent to the glue pasting assembly 500 means that the spatial position of the second end of the track 701 is set close to and adjacent to the glue pasting assembly 500, so that the transfer of the electric core between the glue pasting assembly 500 and the second end of the track 701 is more stable, or when performing other operations that require the connection or cooperation of two mechanisms, the related actions are more stable, and the cooperation is closer, smoother and more efficient.

[0052] The laminator provided in this application is provided with a stacking table assembly 400 on one side of an extended base 100, and a guide rail 101 is provided on the side wall of the base 100. A film covering assembly 300 is provided on the guide rail 101 to cooperate with the stacking table assembly 400 to perform lamination. The glue pasting assembly 500 is provided on the base 100, and the track 701 of the carrier mechanism 700 is extended near the glue pasting assembly 500, thereby increasing the compactness of the space layout, making full use of the existing space, and saving the occupation of the working surface.

[0053] In some embodiments, in order to expand the space in the vertical (height) direction, make full use of the three-dimensional space, and meet the installation requirements of each structural component, in this embodiment, a vertical plate 102 and a glue pasting assembly 500 are respectively provided near both ends of the base 100, and the transmission assembly 200 is provided on the vertical plate 102. The vertical plate 102 has a large installation surface, and the structural components of the transmission assembly 200 can be staggeredly installed on the installation surface along the first direction and the vertical direction. Moreover, the cost of expanding the installation surface through the vertical plate 102 is lower than the cost of only using the base 100 to achieve a corresponding-sized installation surface. Exemplarily, the installation surface of the vertical plate 102 is parallel to the side wall of the base 100, and the transmission assembly 200 is installed on the installation surface, so as to facilitate the transfer of the diaphragm to the film covering assembly 300 installed on the side wall of the base 100.

[0054] In some embodiments, the laminator further includes a negative electrode sheet feeding mechanism 801 and a negative electrode sheet alignment mechanism 802 on one side of the stacking table assembly 400, as well as a positive electrode sheet alignment mechanism 902 and a positive electrode sheet feeding mechanism 901 on the other side of the stacking table assembly 400. Moreover, the negative electrode sheet feeding mechanism 801, the negative electrode sheet alignment mechanism 802, the stacking table assembly 400, the positive electrode sheet alignment mechanism 902, and the positive electrode sheet feeding mechanism 901 are all arranged on the same side of the base 100 and are spaced apart in sequence along the first direction. It should be noted here that, compared with the arrangement of some of these structural components in another direction (at this time, the two-dimensional space is occupied by the first direction and this other direction, and the occupied area or space is relatively large), this arrangement method of being spaced apart in sequence along the first direction in this embodiment (relatively speaking, this embodiment is a one-dimensional arrangement method, and the occupied area or space is relatively small) helps to improve space utilization. In addition, a negative electrode sheet handling assembly is provided above the negative electrode sheet feeding mechanism 801 and the negative electrode sheet alignment mechanism 802, and a positive electrode sheet handling assembly is provided above the positive electrode sheet feeding mechanism 901 and the positive electrode sheet alignment mechanism 902. The negative electrode sheet handling assembly is used to transport the negative electrode battery sheet from the negative electrode sheet feeding mechanism 801 to the negative electrode sheet alignment mechanism 802, and transport the negative electrode battery sheet whose attitude has been aligned in the negative electrode sheet alignment mechanism 802 from the negative electrode sheet alignment mechanism 802 to the stacking table assembly 400 and place it on the separator, so that when the negative electrode sheet is placed on the separator, the attitude of the negative electrode sheet (such as the relative position between the side of the negative electrode sheet and the side of the separator) meets the standard. Similarly, the positive electrode sheet handling assembly is used to transport the positive electrode battery sheet from the positive electrode sheet feeding mechanism 901 to the positive electrode sheet alignment mechanism 90, and transport the positive electrode battery sheet whose attitude has been aligned in the positive electrode sheet alignment mechanism 902 from the positive electrode sheet alignment mechanism 902 to the stacking table assembly 400 and place it on the separator, so that when the positive electrode sheet is placed on the separator, the attitude of the positive electrode sheet (such as the relative position between the side of the positive electrode sheet and the side of the separator) meets the standard.

[0055] In some embodiments, to reduce the redundant setting of similar components and thus reduce the occupation of space, the positive electrode sheet handling assembly and the negative electrode sheet handling assembly can share a guide rail 101 extending along the first direction. Specifically, a guide rail 101 extending along the first direction is provided on the side wall of the base 100. Both the positive electrode sheet handling assembly and the negative electrode sheet handling assembly are arranged on the guide rail 101. Moreover, the negative electrode sheet handling assembly is on the side close to the negative electrode sheet feeding mechanism 801 and the negative electrode sheet alignment mechanism 802, and the positive electrode sheet handling assembly is on the side close to the positive electrode sheet feeding mechanism 901 and the positive electrode sheet alignment mechanism 902. [[ID=],[4]]

[0056] In some embodiments, to facilitate the synchronous handling from the negative electrode sheet feeding mechanism 801 to the negative electrode sheet alignment mechanism 802 and from the negative electrode sheet alignment mechanism 802 to the stacking table assembly 400. The negative electrode sheet handling assembly includes a first negative electrode sheet handling mechanism 803 and a second negative electrode sheet handling mechanism 804 that are both slidably arranged on the guide rail 101 and can be driven to slide reciprocally. The first negative electrode sheet handling mechanism 803 and the second negative electrode sheet handling mechanism 804 being both slidably arranged on the guide rail 101 saves the redundant setting of similar components and space occupation. The first negative electrode sheet handling mechanism 803 is used to handle the negative electrode battery sheet provided by the negative electrode sheet feeding mechanism 801 to the negative electrode sheet alignment mechanism 802 to achieve attitude alignment, and the second negative electrode sheet handling mechanism 804 is used to handle the negative electrode battery sheet on the negative electrode sheet alignment mechanism 802 to the stacking table assembly 400 to achieve lamination.

[0057] In other embodiments, to facilitate the synchronous handling from the positive electrode sheet feeding mechanism 901 to the positive electrode sheet alignment mechanism 902 and from the positive electrode sheet alignment mechanism 904 to the stacking table assembly 400, the positive electrode sheet handling assembly includes a first positive electrode sheet handling mechanism 903 and a second positive electrode sheet handling mechanism 904 that are both slidably arranged on the guide rail 101 and can be driven to slide reciprocally. The first positive electrode sheet handling mechanism 903 and the second positive electrode sheet handling mechanism 904 being both slidably arranged on the guide rail 101 saves the redundant setting of similar components and space occupation. The first positive electrode sheet handling mechanism 903 is used to handle the positive electrode battery sheet provided by the positive electrode sheet feeding mechanism 901 to the positive electrode sheet alignment mechanism 902 to achieve attitude alignment, and the second positive electrode sheet handling mechanism 904 is used to handle the positive electrode battery sheet on the positive electrode sheet alignment mechanism 902 to the stacking table assembly 400 to achieve lamination.

[0058] In some embodiments, the battery cell handling mechanism 600 includes a transverse movement module 601, a lifting module 602, and a picking part 603, where: The transverse movement module 601 is supported and arranged on the side of the stacking table assembly 400 away from the base 100. Specifically, the bracket supporting the transverse movement module 601 and the base 100 are respectively arranged on both sides of the stacking table assembly 400, so that the transverse movement module 601 and the base 100 are distributed on both sides of the stacking table assembly 400 relatively, and the transverse movement module 601 faces the gluing assembly 500, and the transverse movement module 601 extends along the first direction; The lifting module 602 is arranged at the driving end of the transverse movement module 601 to adjust the distance by reciprocating movement of the transverse movement module 601 in the first direction; The picking part 603 is arranged at the driving end of the lifting module 602 to realize the lifting adjustment in the vertical direction (height) relative to the platform by using the lifting module 602. In this way, the picking part 603 transports the battery cells formed by stacking from the stacking table assembly 400 to the gluing assembly 500 and transports the battery cells completed with gluing from the gluing assembly 500 to the carrier mechanism 700 under the action of the transverse movement module 601 (reciprocating movement in the first direction) and the lifting module 602 (lifting in the vertical direction). Such a battery cell handling mechanism 600 arranged relatively to the base 100 and the gluing assembly 500 makes the distance for the battery cell handling mechanism 600 to move to the stacking table assembly 400 to pick up the battery cells shorter, and the path of the battery cells from the stacking table assembly 400 to the gluing assembly 500 is also shorter. Therefore, it helps to reduce the moving distance of the battery cell handling.

[0059] In some embodiments, when the height of the picking part 603 is flush with that of the battery cell, the picking part 603 can move along the first direction under the drive of the transverse movement module 601 (reciprocating movement in the first direction) and the lifting module 602 (lifting in the vertical direction) to move the battery cell away from the stacking table assembly 400. Compared with the battery cell picking action performed perpendicular to the first direction in the same plane, the action along the first direction in this embodiment realizes the battery cell picking, makes full use of the occupied space, and has the advantage of saving space occupation.

[0060] In some embodiments, the first end of the track 701 is the discharging end, and it is arranged at a position below the base 100, which is convenient for manual collection of the battery cells. The first end of the track 701 is located below the base 100, and the second end of the track 701 is close to the gluing assembly 500, so that the track 701 is inclined and arranged on the base 100. This obliquely arranged and extending track 701 increases the layout compactness and improves the space utilization.

[0061] In some embodiments, when the height of the picking part 603 is flush with the height of the gluing operation space inside the gluing assembly 500, the picking part 603 can move along the first direction under the drive of the transverse movement module 601 (reciprocatingly moving in the first direction) and the lifting module 602 (lifting and lowering in the vertical direction) to insert the battery cell into the gluing operation space. For similar reasons as described above, the action of inserting the battery cell into the gluing operation space along the first direction in this way can make full use of the space already occupied by other components.

[0062] In some embodiments, the gluing assembly 500 is fixedly connected to the base 100, and at least part of the gluing assembly 500 deviates to one side of the stacking assembly 400 and is suspended. This way of setting with deviation to one side of the stacking assembly 400 helps to reduce the movement of the battery cell handling mechanism 600.

[0063] It should be noted that the various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. For the same or similar parts among the various embodiments, reference can be made to each other.

[0064] Based on the above description, the position arrangement of the various structural components of the laminator provided by the embodiments of the present application makes reasonable use of space, which helps to reduce the floor area of the laminator and does not affect the production efficiency. Specifically, it includes but is not limited to the following aspects: The transmission assembly 200, the gluing assembly 500 can be arranged on the base 100 formed by the marble long beam, and the common guide rail 101 can be used to support the actions of the first negative electrode sheet handling mechanism 803, the second negative electrode sheet handling mechanism 804, the first positive electrode sheet handling mechanism 903 and the second positive electrode sheet handling mechanism 904; moreover, the transmission assembly 200 is arranged in a higher space by using the vertical plate 102 to avoid occupying the space at a lower height with other structural components.
