Description

Technical Field

[0001] The present application relates to the field of batteries, and in particular to a lug gluing device. Background Art

[0002] Energy conservation and emission reduction are the key to the sustainable development of the automobile industry. Electric vehicles have become an important part of the sustainable development of the automobile industry due to their advantages in energy conservation and environmental protection. For electric vehicles, battery device technology is an important factor related to their development.

[0003] The battery device includes a battery cell. The battery cell includes an electrode assembly and an adapter. The electrode lug of the electrode assembly is welded to the adapter. The welding position of the lug and the adapter needs to be glued, for example, blue tape is pasted. In the glue pasting process, the tape needs to be cut manually, and then the tape is manually pasted on the welding position of the lug and the adapter, and the glue pasting work efficiency is low. Utility Model Content

[0004] In view of the above problems, the present application provides a tab glue sticking device, which can ensure that the two tape segments pasted on the front and back sides of the welding position are accurately aligned with each other and have good overlap, while effectively improving the glue sticking work efficiency.

[0005] The present application provides a lug taping device, which includes a tape support and a cutting assembly. The tape support includes two bearing surfaces arranged opposite to each other. Cutting assemblies are arranged on opposite sides of the tape support, respectively. The cutting assembly includes a main body, an annular cutting blade and a plurality of suction holes. The main body has a positioning plane facing the bearing surface. The annular cutting blade is arranged on the positioning plane. The annular cutting blade protrudes from the positioning plane. The air inlet of the suction hole is arranged on the positioning plane. The annular cutting blade is arranged around the suction hole.

[0006] The lug gluing equipment of the embodiment of the present application includes a tape support and a cutting component. The cutting component can cut the tape and obtain a tape segment, and at the same time, the cutting component can adsorb and fix the tape segment, so that the cutting component itself can achieve cutting and adsorption simultaneously, effectively ensuring the position accuracy of the tape segment. After completing the cutting and adsorption actions, the cutting components arranged on both sides of the tape support can be synchronously moved to the front and back sides of the welding position, and can be glued on the front and back sides of the welding position simultaneously. The tape segments cut by the cutting components arranged on both sides of the tape support are the same in shape and size, so that the two tape segments pasted on the front and back sides of the welding position can be accurately aligned with each other and have good overlap, reducing the possibility of the sticky surfaces of the two tape segments being exposed. At the same time, the lug gluing equipment of the embodiment of the present application replaces the manual gluing process, effectively improving the efficiency of the gluing work.

[0007] In some achievable ways, the tab gluing device further includes a first positioning member and a second positioning member. One of the tape support member and the cutting assembly is provided with the first positioning member, and the other is correspondingly provided with the second positioning member matching the first positioning member.

[0008] When the cutting assembly performs cutting and adsorption actions, the cutting assembly moves along the first direction close to the bearing surface of the tape support. After the cutting assembly moves along the first direction close to the bearing surface of the tape support for a predetermined distance, the first positioning member and the second positioning member contact and align with each other, thereby providing positioning and guidance for the continued movement of the cutting assembly, so as to improve the position accuracy of the cutting assembly and reduce the possibility that the cutting assembly arranged on both sides of the tape support is in an asymmetric state due to positional deviation of the cutting assembly.

[0009] In some achievable embodiments, one of the first positioning member and the second positioning member is a positioning sleeve, and the other is a positioning pin that is plug-matched with the positioning sleeve.

[0010] The structures of the first positioning member and the second positioning member are relatively simple, which is conducive to reducing the difficulty of processing and assembling the first positioning member and the second positioning member.

[0011] In some achievable embodiments, the tape support further comprises a plurality of blowing holes, and the air outlets of the blowing holes are arranged on the bearing surface.

[0012] The air blowing hole of the tape support is used to communicate with the air supply device. When the cutting component moves away from the bearing surface, the air supply device can blow air to the tape segment through the air blowing hole to apply force to the tape segment, so that the tape segment can relatively easily overcome the adhesive force between the sticky surface and the bearing surface, which is conducive to ensuring the smooth separation of the tape segment from the bearing surface and reducing the possibility of the tape segment being torn or detached from the positioning plane due to the adhesion and difficulty in separation of the tape segment from the bearing surface.

[0013] In some possible implementations, the bearing surface is a concave-convex surface.

[0014] When the sticky surface of the tape is bonded to the bearing surface of the tape support, the bearing surface of the tape support is a concave-convex structural design, which can help reduce the bonding area between the sticky surface of the tape and the bearing surface of the tape support, thereby helping to reduce the bonding force between the tape segment and the bearing surface, so that when the cutting component moves away from the bearing surface, the tape segment adsorbed on the cutting component can relatively easily overcome the bonding force between the sticky surface and the bearing surface, thereby ensuring that the tape segment and the bearing surface are smoothly separated.

[0015] In some achievable embodiments, the bearing surface includes a convex portion, and the surface of the convex portion is a spherical surface.

[0016] The convex part of the bearing surface can provide good support for the tape and relatively reduce the bonding area between the tape and the bearing surface. The convex part of the bearing surface is not easy to apply local concentrated stress to the tape, reducing the possibility of the bearing surface squeezing the tape and causing the tape to tear.

[0017] In some achievable embodiments, the tape support comprises a substrate and a non-stick layer. The non-stick layer is disposed on the surface of the substrate and has a bearing surface.

[0018] When the cutting assembly cuts the tape, the sticky surface of the tape adheres to the non-stick layer. The adhesive force between the sticky surface of the tape and the non-stick layer is relatively small, so that when the cutting assembly moves away from the carrying surface, the tape segment adsorbed on the cutting assembly can relatively easily overcome the adhesive force between the sticky surface and the carrying surface, ensuring smooth separation of the tape segment from the carrying surface.

[0019] In some feasible embodiments, the non-stick layer is a Teflon coating or a ceramic particle coating, which helps to ensure that the tape support has good supporting performance. At the same time, the Teflon coating or the ceramic particle coating is stably connected to the substrate, which helps to ensure that the non-stick layer is not easy to peel off from the substrate.

[0020] In some achievable embodiments, the tab gluing device includes a first driving device, the cutting assembly is connected to the first driving device, and the first driving device is used to drive the cutting assembly to move toward or away from the tape support along a first direction.

[0021] The manner in which the first driving device drives the cutting assembly to move can realize automatic control of the movement process of the cutting assembly approaching the tape support, the cutting process, and the movement process away from the tape support, which is beneficial to improving the moving position accuracy of the cutting assembly, thereby helping to reduce the position error of the cutting assembly during glue application, and ensuring that the cutting assembly can accurately stick the tape segment to the predetermined position.

[0022] In some achievable embodiments, the tab gluing device includes a second drive device. The first drive device is connected to the second drive device. The second drive device is used to drive the first drive device and the cutting assembly to move synchronously along the second direction, so that the cutting assembly switches between the cutting station and the gluing station. The first direction is perpendicular to the second direction.

[0023] The second driving device drives the cutting component to switch between the cutting station and the gluing station, which can realize automatic control of the movement process of the cutting component, which is beneficial to improve the movement position accuracy of the cutting component, thereby helping to reduce the position error of the cutting component during gluing, and ensuring that the cutting component can accurately stick the tape segment to the predetermined position.

[0056] It should be understood that the technical solutions described in the embodiments of the present application are not limited to the battery devices and electrical devices described above, but can also be applied to all battery devices including a box and electrical devices using the battery devices. However, for the sake of simplicity, the following embodiments are described using electric vehicles as examples.

[0057] Figure 1 The structure of the vehicle 1 is schematically shown. Figure 1As shown, vehicle 1 can be a fuel vehicle, a gas vehicle or a new energy vehicle. The new energy vehicle can be a pure electric vehicle, a hybrid vehicle or an extended-range vehicle, etc. A battery device 10 is arranged inside the vehicle 1. The battery device 10 can be arranged at the bottom, head or tail of the vehicle 1. The battery device 10 can be used to power the vehicle 1. For example, the battery device 10 can be used as an operating power source for the vehicle 1. The vehicle 1 can also include a controller 11 and a motor 12. The controller 11 is used to control the battery device 10 to power the motor 12. For example, it is used for the working power demand of the vehicle 1 during startup, navigation and driving.

[0058] In some embodiments of the present application, the battery device 10 can not only serve as an operating power source for the vehicle 1 , but also serve as a driving power source for the vehicle 1 , thereby replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1 .

[0059] In order to meet different power requirements, the battery device 10 may include multiple battery cells. A battery cell refers to the smallest unit that constitutes a battery module or a battery pack. Multiple battery cells can be connected in series and / or in parallel via electrode terminals for use in various applications. The battery device 10 mentioned in the present application includes a battery module or a battery pack. Among them, multiple battery cells can be connected in series, in parallel, or in mixed connection. Mixed connection refers to a mixture of series and parallel connection. In the embodiments of the present application, multiple battery cells can directly form a battery pack, or they can first form a battery module 20, and the battery module 20 can then form a battery pack.

[0060] Figure 2 The structure of the battery device 10 is schematically shown. Figure 2 As shown, the battery device 10 includes a housing 10a and a battery cell (not shown). The battery cell is accommodated in the housing 10a.

[0061] The box 10a can be a simple three-dimensional structure such as a single cuboid, cylinder or sphere, or a complex three-dimensional structure composed of simple three-dimensional structures such as cuboids, cylinders or spheres, which is not limited in the present embodiment. The box 10a can be made of alloy materials such as aluminum alloy, iron alloy, polymer materials such as polycarbonate, polyisocyanurate foam plastic, or composite materials such as glass fiber and epoxy resin, which is not limited in the present embodiment.

[0062] The box 10a is used to accommodate battery cells, and the box 10a can be a variety of structures. In some embodiments, the box 10a may include a first box portion 10b and a second box portion 10c. The first box portion 10b and the second box portion 10c cover each other. The first box portion 10b and the second box portion 10c jointly define a storage space for accommodating battery cells. The second box portion 10c may be a hollow structure with one end open. In some embodiments, the first box portion 10b is a plate-like structure. The first box portion 10b covers the open side of the second box portion 10c to form a box 10a with a storage space. In some embodiments, the first box portion 10b and the second box portion 10c may also be hollow structures with one side open. The open side of the first box portion 10b covers the open side of the second box portion 10c to form a box 10a with a storage space. Of course, the first box portion 10b and the second box portion 10c may be in a variety of shapes, such as a cylinder, a cuboid, and the like.

[0063] In order to improve the sealing performance after the first box body 10b and the second box body 10c are connected, a sealing member, such as a sealant, a sealing ring, etc., may also be provided between the first box body 10b and the second box body 10c.

[0064] In some embodiments, the first box body portion 10b covers the top of the second box body portion 10c. The first box body portion 10b can also be called an upper box cover, and the second box body portion 10c can also be called a lower box.

[0065] In the battery device 10, there can be one or more battery cells. When there are multiple battery cells, the multiple battery cells can be connected in series, in parallel, or in mixed connection. Mixed connection means that multiple battery cells are connected in series and in parallel. Multiple battery cells can be directly connected in series, in parallel, or in mixed connection, and then the whole formed by the multiple battery cells is accommodated in the box 10a. Of course, multiple battery cells can also be connected in series, in parallel, or in mixed connection to form a battery module 20. Multiple battery modules 20 are then connected in series, in parallel, or in mixed connection to form a whole, and accommodated in the box 10a.

[0066] In some embodiments, Figure 3 The structure of the battery module 20 is schematically shown. Figure 3 As shown, there may be a plurality of battery cells 30. The plurality of battery cells 30 are first connected in series, in parallel or in series to form a battery module 20. The plurality of battery modules 20 are then connected in series, in parallel or in series to form a whole and are contained in the box 10a.

[0067] The multiple battery cells 30 in the battery module 20 can be electrically connected through a busbar component to achieve parallel connection, series connection, or mixed connection of the multiple battery cells 30 in the battery module 20 .

[0068] In the embodiment of the present application, the battery cell 30 may include a lithium-ion battery cell, a sodium-ion battery cell, or a magnesium-ion battery cell, etc., which is not limited in the embodiment of the present application. The battery cell 30 may be a flat body, a rectangular parallelepiped, or other shapes, which is not limited in the embodiment of the present application. However, for the sake of simplicity, the following embodiment is described by taking a square-shaped battery cell 30 as an example.

[0069] Figure 4 The exploded structure of the battery cell 30 is schematically shown. The battery cell 30 refers to the smallest unit constituting the battery device 10. Figure 4 As shown, the battery cell 30 includes an end cap 40 , a housing 50 and an electrode assembly 60 .

[0070] The end cap 40 refers to a component that covers the opening of the shell 50 to isolate the internal environment of the battery cell 30 from the external environment. Exemplarily, the shape of the end cap 40 can be adapted to the shape of the shell 50 to match the shell 50. Exemplarily, the end cap 40 can be made of a material with a certain hardness and strength (such as aluminum alloy), so that the end cap 40 is not easily deformed when squeezed and collided, so that the battery cell 30 can have a higher structural strength and the safety performance can also be improved. Functional components such as electrode terminals 41 can be provided on the end cap 40. The electrode terminal 41 can be used to be electrically connected to the electrode assembly 60 for outputting or inputting electrical energy of the battery cell 30.

[0071] In some embodiments, the end cap 40 may also be provided with a pressure relief mechanism for releasing the internal pressure when the internal pressure or temperature of the battery cell 30 reaches a threshold value. The material of the end cap 40 may also be various, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc., which is not particularly limited in the embodiments of the present application. In some embodiments, an insulating component may also be provided on the inner side of the end cap 40, and the insulating component may be used to isolate the electrical connection components in the housing 50 from the end cap 40 to reduce the risk of short circuit. Exemplarily, the insulating component may be plastic, rubber, etc.

[0072] The shell 50 is a component used to cooperate with the end cap 40 to form the internal environment of the battery cell 30. Among them, the internal environment formed can be used to accommodate the electrode assembly 60, the electrolyte (not shown in the figure) and other components. The shell 50 and the end cap 40 can be independent components. An opening can be set on the shell 50, and the internal environment of the battery cell 30 is formed by covering the opening with the end cap 40 at the opening. Without limitation, the end cap 40 and the shell 50 can also be integrated. Specifically, the end cap 40 and the shell 50 can form a common connection surface before other components are put into the shell. When it is necessary to encapsulate the interior of the shell 50, the end cap 40 is covered with the shell 50. The shell 50 can be of various shapes and sizes, such as a rectangular parallelepiped, a hexagonal prism, etc. Specifically, the shape of the shell 50 can be determined according to the specific shape and size of the electrode assembly 60. The material of the shell 50 can be various, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc., and the embodiment of the present application does not impose any special restrictions on this.

[0073] The electrode assembly 60 is a component in the battery cell 30 where electrochemical reactions occur. More than two electrode assemblies 60 may be included in the housing 50. Each electrode assembly 60 is mainly formed by winding or stacking 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 materials constitute the main body of the electrode assembly. The parts of the positive electrode sheet and the negative electrode sheet without active materials each constitute a tab. The positive electrode tab and the negative electrode tab may be located together at one end of the main body or respectively at both ends of the main body. During the charge and discharge process of the battery, the positive electrode active material and the negative electrode active material react with the electrolyte, and the tabs connect the electrode terminals to form a current loop.

[0074] In some achievable ways, Figure 5 The connection structure between the electrode assembly 60 and the adapter sheet 70 is schematically shown. Figure 6 The connection structure between the electrode assembly 60 and the tape segment 100 is schematically shown. Figure 5 and Figure 6As shown, the battery cell 30 also includes a transfer plate 70. The pole lug 61 of the electrode assembly 60 is welded to the transfer plate 70. For example, the pole lug 61 and the transfer plate 70 can be connected by ultrasonic welding. The transfer plate 70 is welded to the electrode terminal 41. The transfer plate 70 electrically connects the pole lug 61 and the electrode terminal 41. After the pole lug 61 and the transfer plate 70 are welded, it is necessary to apply glue on the front and back sides of the welding position 80 formed by the pole lug 61 and the transfer plate 70. The tape segments 100 pasted on the front and back sides of the welding position 80 can cover the welding position 80 of the pole lug 61 and the transfer plate 70. Exemplarily, the tape segment 100 can be a blue tape with one side being sticky and the other side being non-sticky. During the welding process of the pole lug 61 and the transfer plate 70, there is a possibility of metal chips appearing at the welding position 80. The pasted tape segment 100 can fix the metal chips that may exist at the welding position 80, effectively reducing the possibility of the metal chips falling and causing the metal chips to electrically connect the positive electrode sheet and the negative electrode sheet, thereby helping to reduce the possibility of short circuit between the positive electrode sheet and the negative electrode sheet.

[0075] In the related art, in the glue sticking process, it is necessary to manually cut the tape to obtain the tape segment, and then manually stick the tape segment to the welding position 80 between the pole ear 61 and the adapter 70, which makes the glue sticking work efficiency low. In addition, after manually sticking the tape segment on the front side of the welding position 80, the tape segment is then stuck on the back side of the welding position 80. Since the tape segments on the front and back sides of the welding position 80 are not accurately aligned with each other and the overlap is deviated, the tape segments on the front and back sides of the welding position 80 are offset from each other, resulting in the sticky surface of the tape segment being exposed. When the sticky surface of the tape segment is exposed, the sticky surface of the tape segment will adhere to the adjacent structural parts (such as the adjacent pole ear 61), so that the tape segment and the structural parts are pulled against each other, resulting in the possibility of damage to the tape segment and the structural parts or displacement of the position.

[0076] The tab gluing equipment of the embodiment of the present application can simultaneously glue the front and back sides of the welding position 80, and is helpful in ensuring that the tape segments on the front and back sides of the welding position 80 are accurately aligned with each other and have good overlap.

[0077] Figure 7 The local structure of the tab gluing equipment is schematically shown. Figure 8 The partial structure of the cutting component is shown schematically. Fig. 9 Schematic diagram showing the partial cross-section of the cut component. Figure 7 , Figure 8 and Fig. 9 As shown, the tab taping device includes a tape support 110 and a cutting assembly 120 .

[0078] The tape support 110 includes two bearing surfaces 111 arranged opposite to each other. Cutting components 120 are arranged on opposite sides of the tape support 110 respectively. The cutting component 120 includes a body 121, an annular cutting blade 122 and a plurality of suction holes 123. The body 121 has a positioning plane 1211 facing the bearing surface 111. The annular cutting blade 122 is arranged on the positioning plane 1211. The annular cutting blade 122 protrudes from the positioning plane 1211. The air inlet of the suction hole 123 is arranged on the positioning plane 1211. The annular cutting blade 122 is arranged around the suction hole 123.

[0079] Fig.10 The partial structure of the cutting assembly 120 and the cutting tape 90 is schematically shown. Fig.11 The schematic diagram shows the partial structure of the cutting assembly 120 adsorbing the tape segment 100. Fig.10 and Fig.11 As shown, the adhesive tape 90 has a sticky surface and a non-sticky surface that are arranged opposite to each other. The adhesive tape 90 to be cut passes between the adhesive tape support 110 and the cutting assembly 120. The sticky surface of the adhesive tape 90 faces the bearing surface 111 of the adhesive tape support 110. The non-sticky surface of the adhesive tape 90 faces the cutting assembly 120. When the cutting assembly 120 partially cuts the adhesive tape 90, the bearing surface 111 of the adhesive tape support 110 is used to support the adhesive tape 90. The annular cutting blade 122 of the cutting assembly 120 and the bearing surface 111 of the adhesive tape support 110 can jointly apply a force to the adhesive tape 90, so that the annular cutting blade 122 partially cuts the adhesive tape 90 and obtains a tape segment 100 of a predetermined shape. The suction hole 123 of the cutting assembly 120 is used to communicate with the negative pressure device. When the negative pressure device is working, the suction hole 123 can generate negative pressure, so that the cut tape segment 100 can be adsorbed on the positioning plane 1211 of the main body 121, so that the cutting component 120 can carry the tape segment 100 to the gluing station to glue the welding position 80. Fig.12 The process of gluing the cutting component 120 is schematically shown. Fig.12 As shown, after the cutting and adsorption actions are completed, the cutting components 120 provided on both sides of the tape support 110 can be synchronously moved to the front and back sides of the welding position 80, and can be glued to the front and back sides of the welding position 80. After the glue application action is completed, the cutting component 120 is separated from the tape segment 100 and returns to the cutting station to cut the next tape segment 100.

[0080] The tab gluing equipment of the embodiment of the present application includes a tape support 110 and a cutting assembly 120. The cutting assembly 120 can cut the tape 90 and obtain the tape segment 100, and at the same time, the cutting assembly 120 can adsorb and fix the tape segment 100, so that the cutting assembly 120 itself can achieve cutting and adsorption synchronously, effectively ensuring the position accuracy of the tape segment 100. After completing the cutting and adsorption actions, the cutting assemblies 120 arranged on both sides of the tape support 110 can be synchronously moved to the front and back sides of the welding position 80, and can be glued on the front and back sides of the welding position 80 synchronously. The tape segments 100 cut by the cutting assemblies 120 arranged on both sides of the tape support 110 are of the same shape and size, so that the two tape segments 100 pasted on the front and back sides of the welding position 80 can be accurately aligned with each other and have good overlap, reducing the possibility of the sticky surfaces of the two tape segments 100 being exposed. At the same time, the tab gluing equipment of the embodiment of the present application replaces the manual gluing process, effectively improving the efficiency of the gluing work.

[0081] With respect to the tape support 110, the cutting assembly 120 disposed on one side of the tape support 110 is symmetrically disposed with the cutting assembly 120 disposed on the other side of the tape support 110. Therefore, the tape segments 100 obtained by cutting the cutting assemblies 120 disposed on both sides of the tape support 110 are of the same shape, the same size, and symmetrical positions, thereby ensuring that the two tape segments 100 pasted on the front and back sides of the welding position 80 are accurately aligned with each other and have good overlap, thereby reducing the possibility that the adhesive surfaces of the two tape segments 100 on the front and back sides of the welding position 80 are exposed.

[0082] In some achievable ways, Fig.13 Schematic diagram showing the partial structure of the tab glue bonding equipment. Fig.13 As shown, the tab gluing device further includes a first positioning member 130 and a second positioning member 140. One of the tape support 110 and the cutting assembly 120 is provided with the first positioning member 130, and the other is correspondingly provided with the second positioning member 140 matching the first positioning member 130.

[0083] When the cutting assembly 120 performs the cutting and adsorption action, the cutting assembly 120 moves along the first direction X close to the bearing surface 111 of the tape support 110. After the cutting assembly 120 moves along the first direction X close to the bearing surface 111 of the tape support 110 for a predetermined distance, the first positioning member 130 and the second positioning member 140 contact and align with each other, thereby providing positioning and guidance for the continued movement of the cutting assembly 120, so as to improve the position accuracy of the cutting assembly 120 and reduce the possibility that the cutting assembly 120 disposed on both sides of the tape support 110 is in an asymmetric state due to the positional deviation of the cutting assembly 120. After the cutting and adsorption action is completed, the cutting assembly 120 moves along the first direction X away from the bearing surface 111 of the tape support 110. After the cutting assembly 120 moves along the first direction X away from the bearing surface 111 of the tape support 110 for a predetermined distance, the first positioning member 130 and the second positioning member 140 are separated from each other.

[0084] In some examples, one of the first positioning member 130 and the second positioning member 140 is a positioning sleeve, and the other is a positioning pin that is plugged and matched with the positioning sleeve.

[0085] The positioning sleeve has a central positioning hole. After the cutting assembly 120 moves a predetermined distance along the first direction X close to the bearing surface 111 of the tape support 110, the positioning pin and the positioning sleeve are plugged into each other along the first direction X, thereby providing positioning and guidance for the cutting assembly 120 to continue to move. The structures of the first positioning member 130 and the second positioning member 140 are relatively simple, which is conducive to reducing the difficulty of processing and assembling the first positioning member 130 and the second positioning member 140.

[0086] Exemplarily, the tape support 110 is provided with a positioning sleeve, and the cutting assembly 120 is provided with a positioning pin. Each cutting assembly 120 may be provided with two positioning pins, and the tape support 110 is provided with two positioning sleeves corresponding to one cutting assembly 120 .

[0087] In some achievable ways, Fig.14 The partial cross-sectional structure of the tab glue sticking equipment is schematically shown. Fig.14 As shown, the tape support 110 further includes a plurality of blowing holes 112 . The air outlets of the blowing holes 112 are disposed on the bearing surface 111 .

[0088] Since the sticky surface of the tape 90 faces the bearing surface 111 of the tape support 110, when the cutting assembly 120 cuts the tape 90, the sticky surface of the tape 90 is bonded to the bearing surface 111. Therefore, when the cutting assembly 120 moves away from the bearing surface 111, the tape segment 100 adsorbed on the cutting assembly 120 needs to overcome the adhesive force between the sticky surface and the bearing surface 111 to separate the tape segment 100 from the bearing surface 111.

[0089] The air blowing hole 112 of the tape support 110 is used to communicate with the air supply device. When the cutting assembly 120 moves away from the carrying surface 111, the air supply device can blow air to the tape segment 100 through the air blowing hole 112 to apply force to the tape segment 100, so that the tape segment 100 can relatively easily overcome the adhesive force between the adhesive surface and the carrying surface 111, which is conducive to ensuring that the tape segment 100 is smoothly separated from the carrying surface 111, and reducing the possibility that the tape segment 100 is torn or separated from the positioning plane 1211 due to the adhesion and difficulty in separation of the tape segment 100 and the carrying surface 111.

[0090] In some achievable ways, Fig.15 The partial structure of the tape support 110 is schematically shown. Fig.15 As shown, the bearing surface 111 of the tape support 110 is a concave-convex surface. The bearing surface 111 of the tape support 110 is a non-flat surface with uneven surfaces.

[0091] When the sticky surface of the tape 90 is bonded to the bearing surface 111 of the tape support 110, the bearing surface 111 of the tape support 110 is a concave-convex structural design, which can help reduce the bonding area between the sticky surface of the tape 90 and the bearing surface 111 of the tape support 110, thereby helping to reduce the adhesion force between the tape segment 100 and the bearing surface 111, so that when the cutting component 120 moves away from the bearing surface 111, the tape segment 100 adsorbed on the cutting component 120 can relatively easily overcome the adhesion force between the sticky surface and the bearing surface 111, thereby ensuring that the tape segment 100 is smoothly separated from the bearing surface 111.

[0092] For some examples, see Fig.15 As shown, the bearing surface 111 of the tape support 110 includes a convex portion 1111. A concave portion is formed between the convex portions 1111 and the convex portions 1111. The surface of the convex portion 1111 of the bearing surface 111 is a spherical surface. Exemplarily, the convex portion 1111 of the bearing surface 111 may be hemispherical. The convex portion 1111 of the bearing surface 111 may provide good support for the tape 90, and at the same time may relatively reduce the bonding area between the tape 90 and the bearing surface 111. The convex portion 1111 of the bearing surface 111 is not easy to apply local concentrated stress to the tape 90, thereby reducing the possibility that the bearing surface 111 squeezes the tape 90 and causes the tape 90 to tear.

[0093] In some examples, Fig.16 Schematically shows a partial cross-sectional structure of the tape support 110. Fig.16 As shown, the tape support 110 includes a base 110a and a non-stick layer 110b. The non-stick layer 110b is disposed on the surface of the base 110a. The non-stick layer 110b has a bearing surface 111.

[0094] When the cutting assembly 120 cuts the adhesive tape 90, the adhesive surface of the adhesive tape 90 adheres to the non-adhesive layer 110b. The adhesive force between the adhesive surface of the adhesive tape 90 and the non-adhesive layer 110b is relatively small, so that when the cutting assembly 120 moves away from the carrying surface 111, the adhesive tape segment 100 adsorbed on the cutting assembly 120 can easily overcome the adhesive force between the adhesive surface and the carrying surface 111, ensuring that the adhesive tape segment 100 is smoothly separated from the carrying surface 111.

[0095] In some examples, the non-stick layer 110b may be a Teflon coating or a ceramic particle coating, which is conducive to ensuring that the tape support 110 has good supporting performance, and the Teflon coating or the ceramic particle coating is stably connected to the substrate 110a, which is conducive to ensuring that the non-stick layer 110b is not easy to peel off from the substrate 110a. Exemplarily, the material of the substrate 110a may be a metal material. For example, the material of the substrate 110a may be aluminum or an aluminum alloy.

[0096] In some achievable ways, Fig.17 Schematic diagram showing the partial structure of the tab glue bonding equipment. Fig.17 As shown, the tab gluing device includes a first driving device 150. The cutting assembly 120 is connected to the first driving device 150. The first driving device 150 is used to drive the cutting assembly 120 to move along the first direction X toward or away from the tape support 110.

[0097] The manner in which the first driving device 150 drives the cutting assembly 120 to move can realize automatic control of the movement process of the cutting assembly 120 approaching the tape support 110, the cutting process, and the movement process away from the tape support 110, which is beneficial to improving the moving position accuracy of the cutting assembly 120, thereby helping to reduce the position error of the cutting assembly 120 during glue application, and ensuring that the cutting assembly 120 can accurately stick the tape segment 100 to the predetermined position.

[0098] In some examples, the first driving device 150 may include a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder. The pneumatic cylinder, the hydraulic cylinder, or the electric cylinder includes a telescopic rod. The telescopic rod of the pneumatic cylinder, the hydraulic cylinder, or the electric cylinder is connected to the cutting assembly 120.

[0099] In some possible implementations, see Fig.17 As shown, the tab gluing device includes a second drive device 160. The first drive device 150 is connected to the second drive device 160. The second drive device 160 is used to drive the first drive device 150 and the cutting assembly 120 to move synchronously along the second direction Y, so that the cutting assembly 120 switches between the cutting station and the gluing station. The first direction X is perpendicular to the second direction Y. In some examples, the first direction X can be a vertical direction, and the second direction Y can be a horizontal direction.

[0100] The second driving device 160 drives the cutting component 120 to switch between the cutting station and the gluing station, which can realize automatic control of the movement process of the cutting component 120, which is beneficial to improve the moving position accuracy of the cutting component 120, thereby helping to reduce the position error of the cutting component 120 during gluing, and ensuring that the cutting component 120 can accurately stick the tape segment 100 to the predetermined position.

[0101] In some examples, the second driving device 160 includes a screw rod 161, an adapter 162, and a motor 163. The screw rod 161 is threadedly connected to the adapter 162. The motor 163 is connected to the screw rod 161. The motor 163 drives the screw rod 161 to rotate, and the screw rod 161 drives the adapter 162 to move along the second direction Y. The first driving device 150 is connected to the adapter 162.

[0102] In some achievable ways, Fig.18 Schematic diagram showing the partial structure of the tab glue bonding equipment. Fig.18 As shown, the tab gluing device further includes a tape feed roll 170 and a tape take-up roll 180. The tape feed roll 170 and the tape take-up roll 180 are located on both sides of the tape support 110, respectively.

[0103] The tape roll can be placed on the tape feed roll 170. The tape 90 released by the tape feed roll 170 can be transported between the tape support 110 and the cutting assembly 120. After the cutting assembly 120 partially cuts the tape 90 to obtain the tape segment 100 to be pasted, the remaining waste tape 90 can enter the tape receiving roll 180 for storage.

[0104] In some examples, the cutting assembly 120 partially cuts the tape 90 to obtain a rectangular tape segment 100 , and a matching rectangular hole is formed on the remaining waste of the tape 90 .

[0105] In some examples, there are two tape feed rolls 170 and two tape take-up rolls 180. The tape 90 released from one tape feed roll 170 can be delivered to one carrying surface 111 of the tape support 110, while the tape 90 released from another tape feed roll 170 can be delivered to the other carrying surface 111 of the tape support 110.
