Description

Technical Field

[0001] The present application relates to the technical field of batteries, and particularly to a tape sticking device and a battery production system. Background Art

[0002] With the popularization and promotion of new energy vehicles, the charging and discharging performance, endurance ability, etc. of new energy vehicles have attracted increasing attention and emphasis. As the power source of new energy vehicles, batteries are widely used.

[0003] During the manufacturing process of battery cells, some processes involve tape sticking steps, and it is necessary to stick tape at the connection between the electrode assembly and the tab. Since the connection between the electrode assembly and the tab has a right-angle structure, the existing tape sticking devices can only stick tape on a single side at a time and cannot well meet the tape sticking requirements of the right-angle structure of battery cells. Summary of the Utility Model

[0004] Based on this, in view of the problem that the existing tape sticking devices cannot well meet the tape sticking requirements of the right-angle structure of battery cells, it is necessary to provide a tape sticking device and a battery production system.

[0005] A tape sticking device is used to adhere a tape to the first surface, the second surface, and the third surface of a battery cell. The third surface and the first surface are perpendicularly connected to opposite sides of the second surface and their extending directions are different. The tape sticking device includes a main tape sticking mechanism and an auxiliary tape sticking mechanism. The main tape sticking mechanism has a first pressing surface and a second pressing surface that are perpendicular to each other. The first pressing surface is used to abut against the first surface, and the second pressing surface is used to abut against the second surface. The auxiliary tape sticking mechanism has a third pressing surface, and the third pressing surface is used to abut against the third surface. Wherein, the auxiliary tape sticking mechanism is movably arranged on the main tape sticking mechanism along a first direction, and the first direction is the height direction of the tape sticking device. In the above tape sticking device, since the auxiliary tape sticking mechanism is movably arranged on the main tape sticking mechanism along the first direction, during the tape sticking process, the main tape sticking mechanism and the auxiliary tape sticking mechanism can have a relative displacement in the first direction. The main tape sticking mechanism adheres part of the tape to the first surface and the second surface of the battery cell, and at the same time, the auxiliary tape sticking mechanism adheres the other part of the tape to the third surface of the battery cell, capable of completing the tape sticking of two horizontal planes and one vertical plane at one time, with high tape sticking efficiency and good sticking effect, and can well meet the tape sticking requirements at the right-angle structure of the battery cell.

[0006] In some of these embodiments, the main tape sticking mechanism includes a first main body, and the auxiliary tape sticking mechanisms are arranged on at least one side of the first main body along a second direction. Each auxiliary tape sticking mechanism can move relative to the first main body along the first direction. The second direction intersects with the first direction and is not coplanar. In this way, the same main tape sticking mechanism cooperates with two auxiliary tape sticking mechanisms, capable of completing the tape sticking of two battery cells at one time, effectively improving the tape sticking efficiency and the sticking effect, and facilitating the simplification of the overall structure of the tape sticking device.

[0007] In some of these embodiments, the main tape sticking mechanism further includes a first protruding portion, which protrudes from one side of the first main body along the first direction, and at least one side of the first protruding portion and the first main body along the second direction enclose an avoidance groove, and the auxiliary tape sticking mechanism is movably disposed in the avoidance groove along the first direction. In this way, the main tape sticking mechanism and the auxiliary tape sticking mechanism can have a relative displacement in the first direction, and the space of the first main body can be fully utilized, making the structure of the main tape sticking mechanism compact and conducive to improving the space utilization rate.

[0008] In some of these embodiments, the first protruding portion has a main bottom surface and a main side surface that are perpendicular to each other. The main bottom surface is configured as the first pressing surface, and the main side surface is configured as the second pressing surface. In this way, the first main body of the main tape sticking mechanism is used to assemble the auxiliary tape sticking mechanism, and the first protruding portion of the main tape sticking mechanism is used to stick the tape to the first surface and the second surface of the battery cell at one time, making the structure of the tape sticking device compact and not affecting the tape sticking efficiency and the sticking effect.

[0009] In some of these embodiments, at least two first adsorption holes are provided on the first pressing surface. Each first adsorption hole penetrates through the first protruding portion along the first direction and is used for adsorbing and fixing the tape. In this way, by generating negative pressure in each first adsorption hole, each first adsorption hole can jointly adsorb and fix the tape, making the tape not easy to fall off during the sticking process and reducing the damage to the tape caused by clamping the tape.

[0010] In some of these embodiments, a first interface and a first through groove are provided inside the first protruding portion. The first through groove is used to communicate each first adsorption hole and the first interface. The first through groove penetrates through the first protruding portion along the third direction. The third direction, the second direction, and the first direction intersect and are not coplanar; the tape sticking device further includes a first negative pressure mechanism. The first interface is connected to the first negative pressure mechanism, and the first negative pressure mechanism is used to generate negative pressure in each first adsorption hole. In this way, the first adsorption hole adsorbs and fixes the tape, and the tape is not easy to fall off during the sticking process; the setting of the first through groove can facilitate the processing of each first adsorption hole and can effectively ensure the sealing performance during vacuum pumping.

[0011] In some of these embodiments, the auxiliary tape sticking mechanism includes a second main body and a second protruding portion. One end of the second protruding portion is movably connected to the first main body, and the end of the second protruding portion away from the first main body is fixedly connected to the second main body. A third pressing surface is provided on the second main body. In this way, the second protruding portion of the auxiliary tape sticking mechanism is movably connected to the first main body, and the second main body of the auxiliary tape sticking mechanism is used to stick the tape, making the auxiliary tape sticking mechanism can be smoothly assembled to the main tape sticking mechanism and not affecting the tape sticking efficiency and the sticking effect.

[0012] In some of these embodiments, the first body has a mounting groove, and one end of the second protruding portion is movably disposed in the mounting groove, and the mounting groove is configured as a groove body that is recessed inward along the bottom of the clearance groove. Thus, one end of the second protruding portion is movably disposed in the mounting groove, which can further utilize the space of the first body of the main adhesive application mechanism, making the overall structure of the adhesive application device more compact.

[0013] In some of these embodiments, the auxiliary adhesive application mechanism further includes an elastic member. A receiving groove is provided on one side of the second protruding portion facing the first body, and the elastic member is received in the receiving groove, and the elastic member is limited between the bottom wall of the receiving groove and the top wall of the mounting groove. Thus, the setting of the elastic member enables the auxiliary adhesive application mechanism to return to its original position after the adhesive application process is completed, and the elastic member is received in the receiving groove without occupying additional space, improving the space utilization rate.

[0014] In some of these embodiments, a positioning post is provided on the bottom wall of the receiving groove. The positioning post protrudes and extends along the first direction, and the elastic member is sleeved outside the positioning post. Thus, during the telescopic process of the elastic member, the setting of the positioning post can reduce the probability of the elastic member being skewed in the first direction, and the auxiliary adhesive application mechanism can better return to its original position.

[0015] In some of these embodiments, in the first direction, the length of the positioning post is equal to the depth of the receiving groove. Thus, during the telescopic process of the elastic member, the elastic member can be better limited and guided, further reducing the probability of the elastic member being skewed in the first direction.

[0016] In some of these embodiments, a first limiting structure is provided in the mounting groove, and a second limiting structure is provided on the second protruding portion. The second limiting structure and the first limiting structure are in limiting cooperation along the first direction. Thus, through the limiting cooperation between the second limiting structure and the first limiting structure, the relative movement between the second protruding portion and the mounting groove of the first body in the first direction can be limited and guided.

[0017] In some of these embodiments, one of the first limiting structure and the second limiting structure is a limiting post, and the other of the first limiting structure and the second limiting structure is a limiting groove. The limiting post is movably inserted into the limiting groove along the first direction. Thus, the limiting post being movably inserted into the limiting groove along the first direction can limit and guide the relative movement between the second protruding portion and the mounting groove of the first body in the first direction.

[0018] In some of these embodiments, the second body has a secondary bottom surface and a secondary side surface that are perpendicular to each other. The secondary side surface is parallel to and abuts against the main side surface, and the secondary bottom surface is configured as a third pressing surface. Thus, the secondary side surface being parallel to and abutting against the main side surface can guide the relative movement between the auxiliary adhesive application mechanism and the main adhesive application mechanism in the first direction, prevent the auxiliary adhesive application mechanism and the main adhesive application mechanism from being skewed, and is conducive to improving the adhesive application efficiency and the bonding effect.

[0019] In some of these embodiments, the third pressing surface is provided with at least two second adsorption holes, and each second adsorption hole penetrates through the second body in the first direction and is used for adsorbing and fixing the tape. In this way, by generating negative pressure in each second adsorption hole, each second adsorption hole can jointly adsorb and fix the tape, making it difficult for the tape to fall off during the pasting process and reducing the damage to the tape caused by clamping the tape.

[0020] In some of these embodiments, a second interface and a second through groove are provided in the second body. The second through groove is used to connect each second adsorption hole and the second interface. The second through groove penetrates through the second body in the third direction, and the third direction, the second direction, and the first direction intersect and are not coplanar; the tape pasting device further includes a second negative pressure mechanism, the second interface is connected to the second negative pressure mechanism, and the second negative pressure mechanism is used to generate negative pressure in each second adsorption hole. In this way, the second adsorption hole adsorbs and fixes the tape, and it is difficult for the tape to fall off during the pasting process; the setting of the second through groove can facilitate the processing of each second adsorption hole and can effectively ensure the sealing performance during vacuum pumping.

[0021] A battery production system includes the above-mentioned tape pasting device. In the above-mentioned battery production system, during the pasting process, the main tape pasting mechanism and the auxiliary tape pasting mechanism can have relative displacement in the first direction. The main tape pasting mechanism adheres part of the tape to the first surface and the second surface of the battery cell, and at the same time, the auxiliary tape pasting mechanism adheres another part of the tape to the third surface of the battery cell, and can complete the pasting of two horizontal planes and one vertical plane at one time, with high pasting efficiency and good pasting effect, and can better meet the pasting requirements at the right-angle structure of the battery cell.

[0042] With the popularization and promotion of new energy vehicles, the charging and discharging performance, endurance ability, etc. of new energy vehicles have attracted increasing attention. As the power source of new energy vehicles, batteries are widely used.

[0043] In the manufacturing process of battery cells, some processes involve gluing steps, and glue needs to be applied at the connection between the electrode assembly and the tab. Since the connection between the electrode assembly and the tab has a right-angle structure, the existing gluing devices can only apply glue on a single side at a time and cannot well meet the gluing requirements of the right-angle structure of battery cells.

[0044] Based on the above considerations, through in-depth research, the present application designs a gluing device and a battery production system. Since the secondary gluing mechanism is movably arranged along the first direction on the main gluing mechanism, during the gluing process, the main gluing mechanism and the secondary gluing mechanism can have a relative displacement in the first direction. The main gluing mechanism adheres part of the tape to the first surface and the second surface of the battery cell, and at the same time, the secondary gluing mechanism adheres another part of the tape to the third surface of the electrode assembly, capable of completing the gluing of two horizontal planes and one vertical plane at one time, with high gluing efficiency and good fitting effect, and can well meet the gluing requirements at the right-angle structure of the electrode assembly.

[0045] In some embodiments of the present application, the battery cell 22 can be a secondary battery or a primary battery; it can also be a lithium-sulfur battery, a sodium-ion battery or a magnesium-ion battery, but is not limited thereto. The battery cell 22 can be in a cylindrical shape, a flat shape, a cuboid shape or other shapes, etc., and the embodiments of the present application are not limited thereto either.

[0046] Please refer to Figure 1 , Figure 1 which is an exploded view of the battery cell 22 provided in some embodiments of the present application. The battery cell 22 includes an end cap 25, a housing 23, an electrode assembly 24 and other functional components.

[0047] The end cap 25 refers to a component that covers the opening of the housing 23 to isolate the internal environment of the battery cell 22 from the external environment. The shape of the end cap 25 can be adapted to the shape of the housing 23 to cooperate with the housing 23. Functional components such as electrode terminals 21a can be provided on the end cap 25. The electrode terminals 21a can be used for electrically connecting with the electrode assembly 24 to output or input the electrical energy of the battery cell 22. The material of the end cap 25 can also be various, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc.

[0048] The housing 23 is a component for cooperating with the end cap 25 to form the internal environment of the battery cell 22. Among them, the formed internal environment can be used to accommodate the electrode assembly 24, the electrolyte, and other components. The housing 23 and the end cap 25 can be independent components. An opening can be provided on the housing 23, and the end cap 25 is covered at the opening to form the internal environment of the battery cell 22. Without limitation, the end cap 25 and the housing 23 can also be integrated. Specifically, the end cap 25 and the housing 23 can first form a common connection surface before other components are put into the housing. When it is necessary to encapsulate the inside of the housing 23, the end cap 25 is then covered on the housing 23. The housing 23 can be of various shapes and sizes, such as rectangular parallelepiped, cylindrical, hexagonal prism, etc. Specifically, the shape of the housing 23 can be determined according to the specific shape and size of the electrode assembly 24. The material of the housing 23 can be various, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc. The embodiments of the present application do not make special restrictions on this.

[0049] The electrode assembly 24 is a component in the battery cell 22 where an electrochemical reaction occurs. The housing 23 can contain one or more electrode assemblies 24. The electrode assembly 24 is mainly formed by winding or laminating a positive electrode sheet and a negative electrode sheet, and a separator is usually provided between the positive electrode sheet and the negative electrode sheet. The parts of the positive electrode sheet and the negative electrode sheet with active substances constitute the main body 24b of the battery core assembly. The parts of the positive electrode sheet and the negative electrode sheet without active substances respectively constitute the electrode tabs 24a. The positive electrode tab and the negative electrode tab can be located at one end of the main body together or at both ends of the main body 24b respectively. During the charging and discharging process of the battery, the positive active substance and the negative active substance react with the electrolyte, and the electrode tabs 24a are connected to the electrode terminals to form a current loop.

[0050] Please refer to Figure 2 and Figure 3 , in one embodiment, the taping device is used to adhere the tape 40 to the first surface 31, the second surface 32, and the third surface 33 of the battery cell 22. The third surface 33 and the first surface 31 are perpendicular to both sides of the second surface 32 along the first direction and their extension directions are different. The taping device includes a main taping mechanism 100 and a secondary taping mechanism 200. The main taping mechanism 100 has a first pressing surface 101 and a second pressing surface 102 that are perpendicular to each other. The first pressing surface 101 is used to abut against the first surface 31, and the second pressing surface 102 is used to abut against the second surface 32. The secondary taping mechanism 200 has a third pressing surface 201, and the third pressing surface 201 is used to abut against the third surface 33. Among them, the secondary taping mechanism 200 is movably disposed on the main taping mechanism 100 along the first direction, and the first direction is the height direction of the taping device.

[0051] It should be noted that the first direction is Figure 2 and Figure 3The X direction shown is also the height direction of the tape - sticking device. During the manufacturing process of the battery cell 22, it is necessary to attach a tape 40 with insulating properties at the connection of the electrode assembly 24 and the tab 24a to prevent the tab 24a from overlapping with the housing 23 and causing a short - circuit.

[0052] Here, the plane where the second surface 32 is located is parallel to Figure 3 the XZ plane shown, and the planes where the third surface 33 and the first surface 31 are located are parallel to Figure 3 the YZ plane shown. The third surface 33 and the first surface 31 are parallel to each other, and the height position of the third surface 33 ( Figure 3 the position in the X direction shown) is higher than the height position of the first surface 31. Optionally, the third surface 33 is the side surface of the main body portion 24b of the electrode assembly 24, the second surface 32 is the end surface of the main body portion 24b of the electrode assembly 24, and the first surface 31 is the side surface of the tab 24a of the electrode assembly 24.

[0053] It should be further noted that the secondary tape - sticking mechanism 200 is movably arranged on the main tape - sticking mechanism 100 along the first direction. The main tape - sticking mechanism 100 is installed on the moving platform. When the moving platform moves downward along the first direction, the main tape - sticking mechanism 100 and the secondary tape - sticking mechanism 200 will move downward synchronously until when the third pressing surface 201 abuts against the third surface 33 of the main tape - sticking mechanism 100, the secondary tape - sticking mechanism 200 is blocked from moving downward continuously; the main tape - sticking mechanism 100 continues to move downward until when the first pressing surface 101 abuts against the first surface 31, the main tape - sticking mechanism 100 stops moving downward. At this time, the second pressing surface 102 abuts against the second surface 32. In this way, the first surface 31, the second surface 32, and the third surface 33 are in a Z - shape as a whole, and the adhered tape 40 is also in a Z - shape.

[0054] In the embodiment of the present application, the main tape - sticking mechanism 100 is a component for adhering a part of the tape 40 to the first surface 31 and the second surface 32 of the battery cell 22. In the main tape - sticking mechanism 100, the first pressing surface 101 is used to abut against the first surface 31, and the second pressing surface 102 is used to abut against the second surface 32. When both the first surface 31 and the second surface 32 are planar structures, both the first pressing surface 101 and the second pressing surface 102 are also planar structures to better press the tape 40.

[0055] In the embodiment of the present application, the secondary tape - sticking mechanism 200 is a component for adhering another part of the tape 40 to the third surface 33 of the battery cell 22. In the secondary tape - sticking mechanism 200, the third pressing surface 201 is used to abut against the third surface 33. When the third surface 33 is a planar structure, the third pressing surface 201 is also a planar structure to better press the tape 40.

[0056] In the above-mentioned tape sticking device, since the secondary tape sticking mechanism 200 is movably arranged on the primary tape sticking mechanism 100 along the first direction, during the tape sticking process, relative displacement can occur between the primary tape sticking mechanism 100 and the secondary tape sticking mechanism 200 in the first direction. The primary tape sticking mechanism 100 adheres part of the tape 40 to the first surface 31 and the second surface 32 of the battery cell 22, and at the same time, the secondary tape sticking mechanism 200 adheres another part of the tape 40 to the third surface 33 of the battery cell 22, enabling the tape sticking of two horizontal planes and one vertical plane to be completed at one time, with high tape sticking efficiency and good fitting effect, and being able to better meet the tape sticking requirements at the right-angle structure of the battery cell 22.

[0057] According to some embodiments of the present application, please refer to Figure 4 and Figure 5 , the primary tape sticking mechanism 100 includes a first main body 110, and at least one side of the first main body 110 along the second direction is provided with a secondary tape sticking mechanism 200. Each secondary tape sticking mechanism 200 can move relative to the first main body 110 along the first direction, and the second direction intersects with the first direction and is not coplanar.

[0058] It should be noted that the second direction is Figure 4 the Y direction shown, that is, the length direction of the tape sticking device.

[0059] In the embodiments of the present application, at least one side of the first main body 110 along the second direction is provided with a secondary tape sticking mechanism 200, which can be understood as: only a secondary tape sticking mechanism 200 is provided on one side of the first main body 110 along the second direction, or secondary tape sticking mechanisms 200 are provided on both opposite sides of the first main body 110 along the second direction. In the case where secondary tape sticking mechanisms 200 are provided on both opposite sides of the first main body 110 in the second direction, the same primary tape sticking mechanism 100 cooperates with two secondary tape sticking mechanisms 200 to be able to complete the tape sticking of two battery cells 22 at one time.

[0060] In the embodiments of the present application, each secondary tape sticking mechanism 200 can move relative to the first main body 110 along the first direction, and the structures of each secondary tape sticking mechanism 200 are the same, which is beneficial for mass production and assembly.

[0061] Through the above settings, the same primary tape sticking mechanism 100 cooperates with two secondary tape sticking mechanisms 200 to be able to complete the tape sticking of two battery cells 22 at one time, which can effectively improve the tape sticking efficiency and the fitting effect, and is beneficial for simplifying the overall structure of the tape sticking device.

[0062] According to some embodiments of the present application, please refer to Figure 5 and Figure 6The main adhesive attaching mechanism 100 further includes a first protruding portion 120. The first protruding portion 120 protrudes from one side of the first main body 110 along the first direction, and at least one side of the first protruding portion 120 and the first main body 110 along the second direction encloses an avoidance groove 130. The secondary adhesive attaching mechanism 200 is movably disposed in the avoidance groove 130 along the first direction.

[0063] In an embodiment of the present application, the first protruding portion 120 protrudes from one side of the first main body 110 along the first direction, which can be understood as: the first protruding portion 120 protrudes from the bottom side of the first main body 110. In the second direction, the length of the first main body 110 is greater than the length of the first protruding portion 120, so that at least one side of the first protruding portion 120 and the first main body 110 along the second direction can enclose an avoidance groove 130. Optionally, when the secondary adhesive attaching mechanisms 200 are provided on opposite sides of the first main body 110 in the second direction, the first protruding portion 120 is located in the middle region of the first main body 110 in the second direction, so that an avoidance groove 130 is respectively formed on opposite sides of the first protruding portion 120 and the first main body 110 along the second direction, and a corresponding secondary adhesive attaching mechanism 200 is disposed in each avoidance groove 130.

[0064] In an embodiment of the present application, the first main body 110 and the first protruding portion 120 are of an integral structure, and are integrally formed by injection molding, casting, etc., having good integrity and high mechanical strength.

[0065] In an embodiment of the present application, the first main body 110 and the first protruding portion 120 are both in a cuboid shape to be adapted to the battery cell 22 of the square shell type. When the battery cell 22 has other shapes, correspondingly, the first main body 110 and the first protruding portion 120 can also be adjusted to other shapes adapted to the battery cell 22.

[0066] Through the above arrangement, the main adhesive attaching mechanism 100 and the secondary adhesive attaching mechanism 200 can have relative displacement in the first direction, and can make full use of the space of the first main body 110, making the structure of the main adhesive attaching mechanism 100 compact and conducive to improving the space utilization rate.

[0067] According to some embodiments of the present application, please refer to Figure 6 The first protruding portion 120 has a main bottom surface 121 and a main side surface 122 that are perpendicular to each other. The main bottom surface 121 is configured as the first pressing surface 101, and the main side surface 122 is configured as the second pressing surface 102.

[0068] It should be noted that the plane where the main bottom surface 121 is located is parallel to Figure 6 the YZ plane shown in Figure 6 and the plane where the main side surface 122 is located is parallel to

[0069] In an embodiment of the present application, the main bottom surface 121 is configured as the first pressing surface 101 and is used to abut against the first surface 31. When the first surface 31 is a planar structure, the main bottom surface 121 is also a planar structure; when the first surface 31 is a curved surface structure, the main bottom surface 121 is also a curved surface structure to better press the tape 40.

[0070] In an embodiment of the present application, the main side surface 122 is configured as the second pressing surface 102 and is used to abut against the second surface 32. When the second surface 32 is a planar structure, the main side surface 122 is also a planar structure; when the second surface 32 is a curved surface structure, the main side surface 122 is also a curved surface structure to better press the tape 40.

[0071] In an embodiment of the present application, the intersection of the first surface 31 and the second surface 32 is a right-angle structure. Correspondingly, the intersection of the main bottom surface 121 and the main side surface 122 is a right-angle structure to better press the tape 40.

[0072] Through the above settings, the first main body 110 of the main tape-applying mechanism 100 is used to assemble the auxiliary tape-applying mechanism 200, and the first extending portion 120 of the main tape-applying mechanism 100 is used to adhesively attach the tape 40 to the first surface 31 and the second surface 32 of the battery cell 22 at one time, making the structure of the tape-applying device compact and not interfering with the tape-applying efficiency and the fitting effect.

[0073] According to some embodiments of the present application, please refer to Figure 7 , at least two first adsorption holes 101a are provided on the first pressing surface 101, and each first adsorption hole 101a penetrates through the first extending portion 120 along the first direction and is used to adsorb and fix the tape 40.

[0074] It should be noted that by generating negative pressure in each first adsorption hole 101a, each first adsorption hole 101a can jointly adsorb and fix the tape 40.

[0075] In an embodiment of the present application, the first adsorption holes 101a are evenly distributed on the first pressing surface 101, and the shapes and sizes of the first adsorption holes 101a are exactly the same, which is beneficial to evenly adsorb and fix the tape 40. For example, each first adsorption hole 101a is a round hole, a square hole or a hole with other shapes having the same diameter.

[0076] Through the above settings, by generating negative pressure in each first adsorption hole 101a, each first adsorption hole 101a can jointly adsorb and fix the tape 40, making the tape 40 not easy to fall off during the attaching process and reducing the damage to the tape 40 caused by clamping the tape 40.

[0077] According to some embodiments of the present application, please refer to Figures 4 to 7, a first interface 123 and a first through groove 124 are provided in the first protruding portion 120. The first through groove 124 is used to communicate with each first adsorption hole 101a and the first interface 123. The first through groove 124 penetrates through the first protruding portion 120 along a third direction. The third direction, the second direction, and the first direction intersect and are not coplanar. The tape sticking device further includes a first negative pressure mechanism. The first interface 123 is connected to the first negative pressure mechanism, and the first negative pressure mechanism is used to generate negative pressure in each first adsorption hole 101a.

[0078] It should be noted that the third direction is Figures 4 to 7 the Z direction shown, that is, the width direction of the tape sticking device.

[0079] Here, the main tape sticking mechanism 100 and the auxiliary tape sticking mechanism 200 jointly adsorb and fix the tape 40. When the moving platform moves downward along the first direction, the main tape sticking mechanism 100 and the auxiliary tape sticking mechanism 200 drive the tape 40 to move downward synchronously until the third pressing surface 201 abuts against the third surface 33 of the main tape sticking mechanism 100, and the auxiliary tape sticking mechanism 200 is blocked from continuing to move downward; the main tape sticking mechanism 100 continues to move downward until the first pressing surface 101 abuts against the first surface 31, and the main tape sticking mechanism 100 stops moving downward. At this time, the second pressing surface 102 abuts against the second surface 32.

[0080] In an embodiment of the present application, the first through groove 124 has a first notch and a second notch that are oppositely arranged along the third direction. The first notch communicates with the first interface 123, and the second notch communicates with the outside. When the first negative pressure mechanism operates, the second notch is blocked by a plug to be isolated from the outside, and the first negative pressure mechanism evacuates the air to form a vacuum environment in the first interface 123, the first through groove 124, and the first adsorption hole 101a, so as to generate negative pressure in each first adsorption hole 101a and adsorb and fix the tape 40. In this way, the setting of the first through groove 124 can facilitate the processing of each first adsorption hole 101a and can effectively ensure the sealing performance during vacuum pumping.

[0081] In an embodiment of the present application, the first negative pressure mechanism is a component for generating negative pressure in each first adsorption hole 101a. Optionally, the first negative pressure mechanism is a vacuum pump.

[0082] In an embodiment of the present application, the number of the first interfaces 123 is one, and the first interface 123 can be a round hole, a square hole, or a hole of other shapes.

[0083] Through the above settings, the first adsorption hole 101a adsorbs and fixes the tape 40, and the tape 40 is not easily dropped during the sticking process; the setting of the first through groove 124 can facilitate the processing of each first adsorption hole 101a and can effectively ensure the sealing performance during vacuum pumping.

[0084] According to some embodiments of the present application, please refer toFigure 8 and Figure 9 The secondary tape - attaching mechanism 200 includes a second main body 210 and a second protruding portion 220. One end of the second protruding portion 220 is movably connected to the first main body 110, and the end of the second protruding portion 220 far from the first main body 110 is fixedly connected to the second main body 210. The third pressing surface 201 is provided on the second main body 210.

[0085] In an embodiment of the present application, the second protruding portion 220 protrudes from the top side of the second main body 210. In the second direction, the length of the second protruding portion 220 is less than or equal to the length of the second main body 210, so that the second protruding portion 220 does not interfere with the second main body 210. Optionally, the second protruding portion 220 is located in the middle region of the second main body 210 in the second direction.

[0086] In an embodiment of the present application, the second main body 210 and the second protruding portion 220 are of an integral structure, for example, integrally formed by injection molding, casting, etc., with good integrity and high mechanical strength.

[0087] In an embodiment of the present application, both the second main body 210 and the second protruding portion 220 are in the shape of a cuboid to be adapted to the square - shell - type battery cell 22. When the battery cell 22 is in other shapes, correspondingly, the second main body 210 and the second protruding portion 220 can also be adjusted to other shapes adapted to the battery cell 22.

[0088] Through the above - mentioned arrangement, the second protruding portion 220 of the secondary tape - attaching mechanism 200 is movably connected to the first main body 110, and the second main body 210 of the secondary tape - attaching mechanism 200 is used for attaching the tape 40, so that the secondary tape - attaching mechanism 200 can be smoothly assembled to the main tape - attaching mechanism 100 without interfering with the tape - attaching efficiency and the fitting effect.

[0089] According to some embodiments of the present application, please refer to Figure 10 , the first main body 110 has an installation groove 111, and one end of the second protruding portion 220 is movably arranged in the installation groove 111. The installation groove 111 is configured as a groove body recessed inward along the bottom of the clearance groove 130.

[0090] It should be noted that the installation groove 111 is configured as a groove body recessed inward along the bottom of the clearance groove 130, which can be understood as: the installation groove 111 is a groove body penetrating through the bottom of the clearance groove 130 along the Figure 10 shown X - direction, and the opening of the groove body is downward.

[0091] In an embodiment of the present application, the second protruding portion 220 is in the shape of a cuboid structure. Correspondingly, the installation groove 111 is also in the shape of a cuboid groove; when the second protruding portion 220 is in the structure of other shapes, the installation groove 111 can also be in the shape of a groove adapted to the second protruding portion 220.

[0092] With the above arrangement, one end of the second protruding portion 220 is movably disposed in the installation groove 111, which can further utilize the space of the first main body 110 of the main adhesive application mechanism 100, making the overall structure of the adhesive application device more compact.

[0093] According to some embodiments of the present application, please refer to Figure 10 , the auxiliary adhesive application mechanism 200 further includes an elastic member 230. A receiving groove 221 is provided on one side of the second protruding portion 220 facing the first main body 110. The elastic member 230 is received in the receiving groove 221, and the elastic member 230 is limited between the bottom wall of the receiving groove 221 and the top wall of the installation groove 111.

[0094] It should be noted that when the moving platform moves downward in the first direction, the main adhesive application mechanism 100 and the auxiliary adhesive application mechanism 200 drive the tape 40 to move downward synchronously until the third pressing surface 201 abuts against the third surface 33 of the main adhesive application mechanism 100. At this time, the auxiliary adhesive application mechanism 200 is blocked from continuing to move downward, and at this time the elastic member 230 is in a compressed state; the main adhesive application mechanism 100 continues to move downward until the first pressing surface 101 abuts against the first surface 31, and the main adhesive application mechanism 100 stops moving downward. The second pressing surface 102 abuts against the second surface 32, and at this time the elastic member 230 is in a compressed state, close to but not reaching the compression limit of the elastic member 230. When the above adhesive application process is completed and the external force is removed, the auxiliary adhesive application mechanism 200 can return to its original position, and at this time the elastic member 230 is in a natural state.

[0095] In the embodiments of the present application, at least a part of the elastic member 230 is received in the receiving groove 221, and the number of the elastic members 230 is not limited to one, that is, at least two elastic members 230 can be provided.

[0096] With the above arrangement, the setting of the elastic member 230 enables the auxiliary adhesive application mechanism 200 to return to its original position after the adhesive application process is completed, and the elastic member 230 is received in the receiving groove 221 without occupying additional space, improving the space utilization rate.

[0097] According to some embodiments of the present application, please refer to Figure 10 , a positioning post 222 is provided on the bottom wall of the receiving groove 221. The positioning post 222 protrudes and extends along the first direction, and the elastic member 230 is sleeved outside the positioning post 222.

[0098] It can be understood that the elastic member 230 is sleeved outside the positioning post 222, and during the telescopic process of the elastic member 230, the elastic member 230 can telescope along the extension direction of the positioning post 222.

[0099] In an embodiment of the present application, the positioning post 222 protrudes from the bottom wall of the receiving groove 221. The positioning post 222 is integrally formed in the receiving groove 221 of the second protruding portion 220, with good integrity and high mechanical strength. Among them, the positioning post 222 is a columnar structure, and the columnar structure includes a cylindrical shape, a prismatic shape or other shapes.

[0100] Through the above arrangement, during the telescopic process of the elastic member 230, the setting of the positioning post 222 can reduce the probability of the elastic member 230 being skewed in the first direction, and the secondary adhesive mechanism 200 can better return to its original position.

[0101] According to some embodiments of the present application, please refer to Figure 2 , in the first direction, the length of the positioning post 222 is equal to the depth of the receiving groove 221.

[0102] It can be understood that during the telescopic process of the elastic member 230, the elastic member 230 can telescopically move along the extending direction of the positioning post 222. The length of the positioning post 222 is equal to the depth of the receiving groove 221, so that the length of the positioning post 222 is long enough to better limit and guide the elastic member 230.

[0103] Through the above arrangement, during the telescopic process of the elastic member 230, the elastic member 230 can be better limited and guided, and the probability of the elastic member 230 being skewed in the first direction is further reduced.

[0104] According to some embodiments of the present application, please refer to Figure 7 , Figure 8 and Figure 10 , a first limiting structure 112 is provided in the installation groove 111, and a second limiting structure 223 is provided on the second protruding portion 220. The second limiting structure 223 and the first limiting structure 112 are in limiting cooperation along the first direction.

[0105] It should be noted that since one end of the second protruding portion 220 is movably arranged in the installation groove 111, the installation groove 111 of the second protruding portion 220 and the first main body 110 can relatively move in the first direction. Through the limiting cooperation between the second limiting structure 223 and the first limiting structure 112, the relative movement between the installation groove 111 of the second protruding portion 220 and the first main body 110 in the first direction can be limited and guided.

[0106] In the embodiments of the present application, the number of the first limiting structure 112 and the second limiting structure 223 is not limited to one. When the number of the first limiting structure 112 and the second limiting structure 223 is at least two, the first limiting structure 112 and the second limiting structure 223 are arranged in one-to-one correspondence, and the first limiting structure 112 and the second limiting structure 223 can be arranged in various ways. For example, when the number of both the first limiting structure 112 and the second limiting structure 223 is two, the two first limiting structures 112 are arranged side by side and spaced apart along Figure 10 the Z direction shown, and correspondingly, the two second limiting structures 223 are arranged side by side and spaced apart along Figure 8 the Z direction shown.

[0107] In the embodiments of the present application, the first limiting structure 112 and the mounting groove 111 can be an integral structure, for example, integrated by injection molding, casting and other methods, with good integrity and high mechanical strength; the first limiting structure 112 and the mounting groove 111 can also be a split structure, for example, fixed by plugging, clamping and other methods, which is convenient for disassembly and assembly.

[0108] In the embodiments of the present application, the second limiting structure 223 and the second protruding portion 220 can be an integral structure, for example, integrated by injection molding, casting and other methods, with good integrity and high mechanical strength; the second limiting structure 223 and the second protruding portion 220 can also be a split structure, for example, fixed by plugging, clamping and other methods, which is convenient for disassembly and assembly.

[0109] Through the above settings, through the limiting cooperation between the second limiting structure 223 and the first limiting structure 112, the relative movement of the second protruding portion 220 and the mounting groove 111 of the first main body 110 in the first direction can be limited and guided.

[0110] According to some embodiments of the present application, please refer to Figure 2 , one of the first limiting structure 112 and the second limiting structure 223 is a limiting post, and the other of the first limiting structure 112 and the second limiting structure 223 is a limiting groove, and the limiting post is movably inserted into the limiting groove along the first direction.

[0111] For example, a limiting post is provided in the mounting groove 111, and a limiting groove is provided in the second protruding portion 220, and the limiting post is movably inserted into the limiting groove along the first direction. When the second protruding portion 220 and the mounting groove 111 of the first main body 110 move relative to each other in the first direction, the limiting post moves in the limiting groove along the first direction. Among them, the limiting post and the mounting groove 111 are a split structure. By opening a hole in the mounting groove 111, the limiting post is fixed in the mounting hole of the mounting groove, and the limiting groove is integrally formed on the second protruding portion 220.

[0112] In the embodiments of the present application, the limiting groove is a groove body extending in the first direction. The limiting groove can be an oval groove or a groove body of other shapes. Here, the shape of the limiting groove is not limited.

[0113] In the embodiments of the present application, the limiting post is a columnar structure. The columnar structure includes a cylindrical shape, a prismatic shape or other shapes. Here, the shape of the limiting post is not limited.

[0114] Through the above settings, the limiting post is movably inserted into the limiting groove along the first direction, and can play a role in limiting and guiding the relative movement of the second protruding portion 220 and the mounting groove 111 of the first main body 110 in the first direction.

[0115] According to some embodiments of the present application, please refer to Figure 6 and Figure 8 , the second main body 210 has a secondary bottom surface 211 and a secondary side surface 212 that are perpendicular to each other. The secondary side surface 212 is parallel to and abuts against the main side surface 122, and the secondary bottom surface 211 is configured as the third pressing surface 201.

[0116] It should be noted that the plane where the secondary bottom surface 211 is located is parallel to the Figure 8 YZ plane shown in Figure 8 , and the plane where the secondary side surface 212 is located is parallel to the

[0117] XZ plane shown in

[0118] In the embodiments of the present application, the secondary bottom surface 211 is configured as the third pressing surface 201 and is used to abut against the third surface 33. When the third surface 33 is a planar structure, the secondary bottom surface 211 is also a planar structure; when the third surface 33 is a curved surface structure, the secondary bottom surface 211 is also a curved surface structure to better press the tape 40.

[0119] Through the above settings, the secondary side surface 212 is parallel to and abuts against the main side surface 122, and can play a role in guiding the relative movement of the secondary tape sticking mechanism 200 and the main tape sticking mechanism 100 in the first direction, avoiding skewing of the secondary tape sticking mechanism 200 and the main tape sticking mechanism 100, and facilitating improving the tape sticking efficiency and the sticking effect.

[0120] According to some embodiments of the present application, please refer to Figure 9 , at least two second adsorption holes 201a are provided on the third pressing surface 201. Each second adsorption hole 201a penetrates through the second main body 210 along the first direction and is used for adsorbing and fixing the tape 40.

[0121] It should be noted that by generating a negative pressure in each second adsorption hole 201a, each second adsorption hole 201a can jointly adsorb and fix the tape 40.

[0122] In the embodiments of the present application, each second adsorption hole 201a is evenly distributed on the third pressing surface 201, and the shapes and sizes of each second adsorption hole 201a are exactly the same, which is conducive to evenly adsorbing and fixing the tape 40. For example, each second adsorption hole 201a is a round hole, a square hole or a hole of other shapes with the same diameter.

[0123] Through the above settings, by generating a negative pressure in each second adsorption hole 201a, each second adsorption hole 201a can jointly adsorb and fix the tape 40, so that the tape 40 is not easy to fall off during the pasting process, and the damage to the tape 40 caused by clamping the tape 40 is reduced.

[0124] According to some embodiments in the present application, please refer to Figure 8 and Figure 9 , a second interface 213 and a second through groove 214 are provided in the second main body 210. The second through groove 214 is used to communicate each second adsorption hole 201a and the second interface 213. The second through groove 214 penetrates through the second main body 210 along the third direction. The third direction, the second direction and the first direction intersect and are not coplanar; the tape pasting device further includes a second negative pressure mechanism. The second interface 213 is connected to the second negative pressure mechanism, and the second negative pressure mechanism is used to generate a negative pressure in each second adsorption hole 201a.

[0125] It should be noted that the third direction is Figure 8 and Figure 9 the Z direction shown, that is, the width direction of the tape pasting device.

[0126] Here, the main tape pasting mechanism 100 and the auxiliary tape pasting mechanism 200 jointly adsorb and fix the tape 40. When the moving platform moves downward along the first direction, the main tape pasting mechanism 100 and the auxiliary tape pasting mechanism 200 drive the tape 40 to move downward synchronously until the third pressing surface 201 abuts against the third surface 33 of the main tape pasting mechanism 100, and the auxiliary tape pasting mechanism 200 is blocked from continuing to move downward; the main tape pasting mechanism 100 drives another part of the tape 40 to continue to move downward until the first pressing surface 101 abuts against the first surface 31, and the main tape pasting mechanism 100 stops moving downward. At this time, the second pressing surface 102 abuts against the second surface 32.

[0127] In an embodiment of the present application, the second through groove 214 has a third notch and a fourth notch disposed opposite to each other in the third direction. The third notch communicates with the second interface 213, and the fourth notch communicates with the outside. When the second negative pressure mechanism operates, the fourth notch is blocked by a plug to be isolated from the outside, and the second negative pressure mechanism evacuates the air to form a vacuum environment in the second interface 213, the second through groove 214, and the second adsorption holes 201a, so that negative pressure is generated in each of the second adsorption holes 201a to adsorb and fix the tape 40. Thus, the provision of the second through groove 214 facilitates the machining of each of the second adsorption holes 201a and can effectively ensure the sealing performance during vacuum pumping.

[0128] In an embodiment of the present application, the second negative pressure mechanism is a component for generating negative pressure in each of the second adsorption holes 201a. Optionally, the second negative pressure mechanism is a vacuum pump.

[0129] In an embodiment of the present application, the number of the second interfaces 213 is one, and the second interface 213 can be a round hole, a square hole, or a hole of other shapes.

[0130] Through the above settings, the second adsorption holes 201a adsorb and fix the tape 40, and the tape 40 is not likely to fall off during the pasting process; the provision of the second through groove 214 facilitates the machining of each of the second adsorption holes 201a and can effectively ensure the sealing performance during vacuum pumping.

[0132] It should be noted that the battery production system further includes an assembling device, which is disposed downstream of the tape pasting device and is used for receiving the electrode assembly with tape pasted by the tape pasting device and performing subsequent assembly.

[0133] In the above-mentioned tape pasting device, during the tape pasting process, the main tape pasting mechanism 100 and the auxiliary tape pasting mechanism 200 can displace relative to each other in the first direction. The main tape pasting mechanism 100 adheres part of the tape 40 to the first surface 31 and the second surface 32 of the battery cell 22, and at the same time, the auxiliary tape pasting mechanism 200 adheres the other part of the tape 40 to the third surface 33 of the battery cell 22, so that the tape pasting of two horizontal planes and one vertical plane can be completed at one time, with high tape pasting efficiency and good pasting effect, and can preferably meet the tape pasting requirements at the right-angle structure of the battery cell 22.
