Description

Technical Field

[0001] This application belongs to the field of battery manufacturing technology, and more specifically, relates to an adhesive application device and battery manufacturing equipment. Background Technology

[0002] Energy conservation and emission reduction are key to the sustainable development of the automotive industry, and electric vehicles, due to their energy-saving and environmentally friendly advantages, have become an important component of this sustainable development. For electric vehicles, battery technology is a crucial factor in their development.

[0003] Adhesive layers are often applied to the sides of individual battery cells along their length. Current adhesive application devices typically apply the adhesive layer to the sides of each individual battery cell separately, which is inefficient. Utility Model Content

[0004] The purpose of this application is to provide an adhesive application device and battery production equipment to improve the problem of low efficiency in applying adhesive to the sides of battery cells in related technologies.

[0005] In a first aspect, embodiments of this application provide an adhesive applicator, comprising:

[0006] A tray is used to support a battery cell assembly, which includes a plurality of battery cells arranged along a first direction. The sides of the plurality of battery cells along a second direction form the side surface of the battery cell assembly. The tray has an opening for exposing the side surface. The first direction is perpendicular to the second direction.

[0007] A conveyor line for conveying a tray supporting a battery cell assembly along a first direction;

[0008] The adhesive applicator, located on one side of the conveyor line, is used to drive the tape roll to release the tape and apply the released tape to the side surface of the battery cell assembly on the tray.

[0009] In the technical solution of this application embodiment, an opening is provided on one side of the tray to expose the side surface of the battery cell assembly, and an adhesive applicator is provided on one side of the conveyor line. As the conveyor line drives the tray supporting the battery cell assembly through the adhesive applicator, the adhesive applicator can release the tape roll and apply the tape to the side surface of the battery cell assembly, thereby achieving one-time application of tape to the side of each battery cell in the battery cell assembly, resulting in high adhesive applicator efficiency.

[0010] In some embodiments, the tray includes:

[0011] A tray, used to support individual battery cells;

[0012] Two clamping seats are respectively located at both ends of the tray along the first direction, for use in clamping the battery cell assembly;

[0013] A substrate is disposed on one side of a tray along the second direction for positioning the battery cell assembly along one side of the second direction.

[0014] Along the second direction, an opening is formed between the other side of the tray and the clamping seat.

[0015] The above technical solution involves setting up a tray to support the battery cell assembly, and setting clamps at both ends of the tray to clamp and fix the battery cell assembly on the tray so that the conveyor line can transport the battery cell assembly along the first direction; and setting a substrate on one side of the tray along the second direction to position each battery cell in the battery cell assembly along one side of the second direction, thereby positioning the battery cell along the other side of the second direction, so that the side surface of the battery cell assembly is flatter, so that when the conveyor line transports the battery cell assembly along the first direction, adhesive can be applied to the side surface.

[0016] In some embodiments, the substrate is movably mounted on a tray, the tray including a pushing component for driving the substrate to move in a second direction, the pushing component being mounted on the tray.

[0017] The above technical solution involves setting a push component driving substrate along a second direction to push the side surface of the battery cell assembly toward the opening of the tray, which facilitates the application of adhesive to the side surface of the battery cell assembly.

[0018] In some embodiments, the tray includes a support plate for carrying a battery cell assembly, the support plate being slidably mounted on the pallet along a second direction.

[0019] The above technical solution involves setting up a support plate to movably support the battery cell assembly on the tray, so as to facilitate the pushing of the battery cell assembly along the second direction, which pushes the battery cell assembly toward the opening of the tray.

[0020] In some embodiments, the pallet includes a guide assembly for guiding the carrier plate to move in a second direction, the guide assembly being mounted on the pallet and the carrier plate being mounted on the guide assembly.

[0021] By using the above technical solution, the guide component can be set up to facilitate the sliding support of the carrier plate on the tray along the second direction, so that the substrate can push the battery cell assembly to move along the second direction, so as to push the side surface of the battery cell assembly toward the opening of the tray.

[0022] In some embodiments, at least one clamping seat is equipped with a pressing mechanism; the pressing mechanism includes a pressure plate for pushing the battery cell assembly and a pushing component for driving the pressure plate to move in a first direction, the pressure plate being disposed between two clamping seats and the pushing component being mounted on the respective clamping seat.

[0023] With the above technical solution, the battery cell assembly is placed on the tray, and the pusher assembly pushes the pressure plate along the first direction to press the end of the battery cell assembly, thereby clamping and fixing the battery cell assembly so that the tray supports the battery cell assembly and the tray drives the battery cell assembly to move along the first direction so as to apply adhesive to the side surface of the battery cell assembly.

[0024] In some embodiments, the conveyor line includes a support, a conveyor belt, a drive shaft, a driven shaft, and a drive mechanism; the drive shaft and the driven shaft cooperate to open the conveyor belt, which is used to support the pallet; the drive shaft and the driven shaft are rotatably mounted on the support, the drive mechanism is mounted on the support, the drive mechanism is connected to the drive shaft, and the drive mechanism is used to drive the drive shaft to rotate, so as to drive the conveyor belt to rotate and move in a first direction, so as to drive the pallet to move in the first direction.

[0025] The above technical solution involves driving the drive shaft to rotate via a drive mechanism, which in turn drives the conveyor belt to rotate and move in the first direction. This allows the pallet supporting the battery cell assembly to be placed on the conveyor belt, and the conveyor belt can move the pallet and the battery cell assembly in the first direction to apply adhesive to the battery cell assembly.

[0026] In some embodiments, the conveyor belt includes at least two conveyor chains spaced apart along a second direction, the at least two conveyor chains cooperating to support the tray, and sprockets connecting each conveyor chain are respectively mounted on the drive shaft and the driven shaft.

[0027] The above technical solution involves at least two conveyor chains spaced apart along the second direction to stably support the tray and drive the tray and the battery cell assembly on it to move smoothly along the first direction. Sprockets are installed on the drive shaft and driven shaft to engage with the conveyor chains, supporting and driving the conveyor chains to rotate along the first direction. Furthermore, the use of the conveyor chains and sprockets allows for easy control of the movement position of the conveyor chains along the first direction, thereby enabling good control of the movement position of the battery cell assembly along the first direction and accurate application of adhesive to the side surface of the battery cell assembly.

[0028] In some embodiments, the support is provided with limiting blocks on both sides along the second direction to cooperate in limiting the opposite sides of the tray to confine the tray to the conveyor belt.

[0029] The above technical solution involves setting a limiting block on the support to position the pallet, making it easier to place the pallet on the conveyor belt so that the conveyor belt can smoothly move the pallet along the first direction.

[0030] In some embodiments, the conveyor line includes a positioning module for limiting the position of the tray along a first direction, the positioning module including:

[0031] The positioning assembly includes a sensor for sensing that the tray has reached a set position, a jacking member for jacking to position the tray, and a first linear module for driving the jacking member to move up and down, the first linear module being mounted on a bracket; and / or,

[0032] The limiting assembly includes a stop for moving the stop tray in a first direction and a second linear module for driving the stop to move up and down, the second linear module being mounted on a bracket.

[0033] The above technical solution incorporates a positioning module. If a problem occurs during the adhesive application process, the positioning module can promptly locate the pallet for repair. The positioning module uses positioning components. As the pallet moves on the conveyor belt, when an error occurs during adhesive application and is detected by a sensor, the pallet is positioned correctly. The first linear module then drives a top actuator to rise, supporting the pallet and pausing it for repair.

[0034] With the above technical solution, the positioning module uses a limiting component. If a problem occurs during the adhesive application process, the second linear module drives the stop to rise, thereby blocking the pallet being conveyed on the conveyor belt and pausing the pallet for maintenance.

[0035] Through the above technical solution, the positioning module uses positioning components and limiting components to better position and pause the pallets conveyed by the conveyor belt, facilitating manual intervention for maintenance.

[0036] In some embodiments, the adhesive applicator is used to detect a detection module for the position of battery cell components on the tray, the detection module comprising:

[0037] A ranging sensor is used to detect the position of the battery cell assembly along a first direction, and a ranging sensor is provided on at least one side of the conveyor line along a second direction; and / or,

[0038] A vision sensor is used to identify the shape of the side surface of the battery cell assembly in order to determine the adhesive application position on the side surface. The vision sensor is located on the side of the conveyor line where the opening is located.

[0039] The above technical solution uses a detection module to determine the position of the battery cell assembly on the tray, enabling accurate application of tape to the side surface of the battery cell assembly. The detection module uses a distance sensor to easily detect the starting position of the battery cell assembly on the tray, facilitating accurate tape application to the side surface. The detection module also uses a vision sensor to identify the shape and position of the side surface of the battery cell assembly, ensuring accurate tape application to the side surface.

[0040] In some embodiments, the adhesive applicator includes:

[0041] The feeding module is used to support the tape roll and drive the tape to feed and release the tape.

[0042] The bonding module includes a pressure head for bonding the tape released by the feeding module to a side surface, and the pressure head is provided with a flexible buffer pad for elastically resisting the side surface.

[0043] The material collection module is used to recycle the protective layer on the tape.

[0044] The above technical solution involves setting up a feeding module to release the tape. The tape passes through a pressure head and is adhered to the side surface of the battery cell assembly by the pressure head. The protective layer on the tape is collected by a receiving module so that the tape can be adhered to the side surface of the battery cell assembly. A flexible buffer pad is set on the pressure head, which can both press the tape against the side of the battery cell and provide elastic buffer space to play a good protective role and reduce the risk of scratching the side of the battery cell.

[0045] Secondly, embodiments of this application provide a battery production apparatus, including an adhesive applicator as described in the above embodiments.

[0046] The above description is only an overview of the technical solution of this application. In order to better understand the technical means of this application and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this application more obvious and understandable, the following are specific embodiments of this application.

[0067] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0068] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms “comprising” and “having”, and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion.

[0069] In the description of the embodiments of this application, technical terms such as "first" and "second" are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, specific order, or primary and secondary relationship of the indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0070] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments in any suitable manner.

[0071] Unless otherwise specified, all embodiments and optional embodiments of this application can be combined to form new technical solutions.

[0072] Unless otherwise specified, all technical features and optional technical features of this application may be combined to form new technical solutions.

[0073] In the description of the embodiments in this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0074] In the description of the embodiments of this application, the term "multiple" refers to two or more (including two), similarly, "multiple sets" refers to two or more (including two sets), and "multiple pieces" refers to two or more (including two pieces). "Several" means one or more, unless otherwise explicitly specified.

[0075] In the description of the embodiments of this application, the technical terms "center", "longitudinal", "lateral", "length", "width", "thickness", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

[0076] In the description of the embodiments of this application, unless otherwise expressly specified and limited, the technical terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0078] In the description of the embodiments in this application, unless otherwise expressly specified and limited, the technical term "proximity" refers to being close in location. For example, among three components A1, A2, and B, the distance between A1 and B is greater than the distance between A2 and B. Therefore, A2 is closer to B than A1, meaning A2 is adjacent to B, or B is adjacent to A2. Similarly, when there are multiple components C, namely C1, C2, ..., C... N If one of the C components, such as C2, is closer to the B component than the other C components, then B is adjacent to C2, or C2 is adjacent to B.

[0079] A battery pack typically consists of a casing and individual battery cells housed within it. The casing generally comprises a main body and a cover. The main body is the shell structure that encloses a storage space with an open top. After the battery cells are installed in the main body, the cover is attached to the main body and covers the opening of the storage space to protect the battery cells. The process of installing the battery cells into the main body is generally referred to as packing.

[0080] Before being packaged, battery cells are usually covered with adhesive or tape along their length (hereinafter referred to as the side of the battery cell). This allows the side of the battery cell to be bonded to the side of the adjacent battery cell after it is installed in the housing, thereby improving the stability of the battery cell installation.

[0081] Currently, the common method for applying adhesive to the sides of battery cells is to cut adhesive tape into strips that fit the dimensions of the battery cell's side surface, and then use a robotic arm to attach the strips to the side of the battery cell. This method of applying adhesive to the sides of battery cells is inefficient.

[0082] Based on the above considerations, in order to improve the low efficiency of side adhesive application for battery cells in related technologies, this application provides an adhesive application device. A tray is provided to support multiple battery cells arranged along a first direction to form a battery cell assembly. An opening is provided on one side of the tray along a second direction perpendicular to the first direction. After the battery cell assembly is installed on the tray, the side surface of the battery cell assembly formed by the sides of the multiple battery cells can be exposed through the opening. A conveyor line is provided, and an adhesive application mechanism is provided on one side of the conveyor line. The conveyor line can drive the tray supporting the battery cell assembly to move along the first direction. As the battery cell assembly passes through the adhesive application mechanism, the adhesive application mechanism can apply adhesive tape to the side surface of the battery cell assembly, thereby achieving simultaneous adhesive application to multiple battery cells forming the battery cell assembly, significantly improving the adhesive application efficiency.

[0083] The linear module mentioned in the embodiments of this application is also called a linear drive module or linear module; a linear module refers to a device, component, module, or mechanism that can drive structural parts to move linearly. A linear drive module can be a linear module, a lead screw and nut mechanism, a gear and rack mechanism, a cylinder, a hydraulic cylinder, etc. When using the linear drive module mentioned in the embodiments of this application, it can be any one of a linear module, a lead screw and nut mechanism, a gear and rack mechanism, a cylinder, or a hydraulic cylinder, and can be specifically configured and used as needed.

[0084] The linear module mentioned in the embodiments of this application is also known as a linear module, linear slide, etc. Currently, widely used linear modules can be divided into: synchronous belt type, ball screw type, and linear motor type. When the linear drive module mentioned in the embodiments of this application uses a linear module, any one of the synchronous belt type linear module, ball screw type linear module, and linear motor type linear module can be used, and the specific settings and uses can be made according to needs.

[0085] Synchronous belt type linear modules mainly include belts, linear guides, couplings, and motors. The working principle of the synchronous belt type is as follows: the belt is installed on the drive shafts on both sides of the linear module, one of which is connected to the motor as a power input shaft; a slider for connecting the workpiece is fixed on the belt. When the drive shaft rotates, it drives the belt to move, which in turn drives the slider to move linearly.

[0086] The ball screw type linear module mainly includes a ball screw, linear guide, ball screw support, motor, etc.

[0087] A ball screw is a product that converts rotary motion into linear motion, or vice versa. A ball screw mainly consists of a screw and a nut. The screw is a rod-shaped structure with external threads. The nut is a structure with internal threads. The external threads of the screw and the internal threads of the nut mate to allow the nut to be mounted on the screw. Rotation of the screw causes the nut to move along it, thus converting rotary motion into linear motion. Connecting the workpiece to the nut allows the workpiece to move linearly as the nut moves. Some ball screws also include balls, which primarily reduce the frictional resistance between the nut and the screw.

[0088] Linear guides, also known as slide rails, linear guides, or linear slide rails, are used in linear reciprocating motion applications. They can withstand a certain amount of torque and achieve high-precision linear motion under high loads.

[0089] A linear motor module, also known as a linear motor, is a transmission device that directly converts electrical energy into linear motion mechanical energy without the need for any intermediate conversion mechanism.

[0090] The lead screw and nut mechanism mainly consists of a lead screw, a nut, and a motor. The nut is mounted on the lead screw, which is connected to the motor. The motor drives the lead screw to rotate, thus pushing the nut to move along the lead screw, achieving linear movement of the nut. When the workpiece is connected to the nut, the linear movement of the nut can drive the workpiece to move linearly as well.

[0091] A gear and rack mechanism mainly consists of a gear, a rack, and a motor. The gear meshes with the rack, and the gear is connected to the motor. The motor drives the gear to rotate, which in turn propels the rack to move linearly. When a workpiece is connected to the rack, the linear movement of the rack can drive the workpiece to move linearly as well. A rack is a component with multiple teeth evenly distributed along its length. A gear is a wheel-shaped component with multiple teeth evenly distributed on its outer circumference.

[0092] A cylinder is a mechanical component that guides a piston to perform linear reciprocating motion within the cylinder. A cylinder mainly includes a cylinder barrel, end caps, a piston, a piston rod, and seals. The end cap covers the end of the cylinder barrel, the piston rod is connected to the piston, and the piston is slidably mounted within the cylinder barrel. The piston rod extends out of the cylinder barrel through the end cap, and the seals seal the area between the piston rod and the end cap. It works by filling the cylinder barrel with high-pressure gas to one side of the piston, thus pushing the piston to move linearly within the cylinder barrel, which in turn pushes the piston rod to move linearly along the cylinder barrel. When the workpiece is connected to the piston rod, the linear movement of the piston rod causes the workpiece to move linearly as well.

[0093] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy to perform linear reciprocating motion (or oscillating motion). A hydraulic cylinder generally includes a cylinder barrel, cylinder head, piston, piston rod, and sealing devices. The cylinder head covers the end of the cylinder barrel, the piston rod is connected to the piston, the piston is slidably mounted in the cylinder barrel, and the piston rod extends out of the cylinder barrel through the cylinder head. Seals seal the piston rod and cylinder head. It primarily works by filling the cylinder barrel with high-pressure fluid to one side of the piston, pushing the piston to move linearly within the cylinder barrel, which in turn pushes the piston rod to move linearly along the cylinder barrel. When the workpiece is connected to the piston rod, the linear movement of the piston rod drives the workpiece to move linearly.

[0094] The guiding component mentioned in the embodiments of this application, also known as a guide assembly, refers to a component used to guide the movement of an object. As an example, a guiding component may include a guide rail and a slider. The slider is slidably placed on the guide rail, connecting the slider to the object. The guide rail is mounted on a support medium to support the object on the support medium and guide the object to move along the guide rail. As an example, a guiding component may include two slide rails slidably connected to each other. One slide rail is connected to the object, and the other slide rail is connected to the support medium to movably support the object on the support medium and guide the object to move along the slide rail. As an example, a guiding component may include a guide rod and a sleeve fitted on the guide rod. The sleeve is connected to the object, and the guide rod is mounted on the support medium to support the object on the support medium and guide the object to move along the guide rod.

[0095] In this embodiment of the application, the battery cell can be a secondary battery, which refers to a battery cell that can be recharged to activate the active materials and continue to be used after the battery cell has been discharged.

[0096] The battery cell can be a lithium-ion battery, sodium-ion battery, sodium-lithium-ion battery, lithium metal battery, sodium metal battery, lithium-sulfur battery, magnesium-ion battery, nickel-metal hydride battery, nickel-cadmium battery, lead-acid battery, etc., and the embodiments of this application are not limited to this.

[0097] As an example, the battery cell can be a cylindrical battery cell, a prismatic battery cell, a pouch battery cell, or a battery cell of other shapes. Prismatic battery cells include prismatic battery cells, blade-shaped battery cells, and multi-prismatic batteries, such as hexagonal prismatic batteries. This application does not have any particular limitations.

[0098] Please refer to Figure 1 The battery device 100 mentioned in the embodiments of this application may include one or more battery cell assemblies 20 for providing voltage and capacity. The battery cell assembly 20 may include multiple battery cells 21, which are connected in series, parallel or mixed connection through a busbar.

[0099] In some embodiments, the battery cell assembly 20 is typically formed by arranging a plurality of battery cells 21.

[0100] As an example, the battery cell assembly 20 can be a battery module, which is formed by arranging and fixing multiple battery cells 21 together to form an independent module. As an example, the battery module can be formed by bundling multiple battery cells 21 together with cable ties.

[0101] In some embodiments, the battery device 100 may be a battery pack, which includes a housing 10 and one or more battery cell assemblies 20, the battery cell assemblies 20 being housed within the housing 10.

[0102] As an example, the battery cell assembly 20 can be a battery module, which can be housed in the housing 10 by fixing the battery module in the housing 10.

[0103] As an example, the battery cell assembly 20 can also be housed in the housing 10 by directly fixing multiple battery cells 21 to the housing 10.

[0104] As an example, the housing 10 may include a main body 11 and a cover 12, with the cover 12 covering the main body 11 to form a closed space inside the housing 10 for housing the battery cells 21. Here, "closed" refers to covering or shutting off; it can be sealed or unsealed. The main body 11 is a shell structure with an open-sided receiving space inside. The main body 11 includes a frame 111 and a base plate 112. The frame 111 is a portion of the structure forming the peripheral sidewalls of the housing 10, and the base plate 112 is the plate structure at the bottom of the housing body 11 that forms the receiving space. The cover 12 is the plate structure that covers the receiving space of the main body 11.

[0105] As an example, the housing 10 may include a first housing and a second housing. The first housing and the second housing are fastened together to form a closed space inside the housing 10 to house the battery cell assembly 20. Here, "closed" refers to covering or closing, and can be either sealed or unsealed. The first housing may be a cover 12 or a base plate 112.

[0106] Please see Figure 1 Each battery cell 21 has a length, width, and height, with the length being greater than or equal to its width. The height of the battery cell 21 can be parallel to the depth direction of the accommodating space of the housing body 11; that is, the height direction of the battery cell 21 is parallel to the height direction Z of the housing body 10. As an example, the length direction of the battery cell 21 can be parallel to the length direction X of the housing body 10. As an example, the length direction of the battery cell 21 can be parallel to the width direction Y of the housing body 10. As an example, the length direction of the battery cell 21 can be tilted relative to the length direction X of the housing body 10.

[0107] In some embodiments, please refer to Figure 1 A plurality of battery cells 21 of the battery cell assembly 20 are arranged along a first direction M. In some embodiments, the battery cell 21 has a height, a length, and a width, wherein the length of the battery cell 21 is greater than or equal to the width of the battery cell 21. The end face of the battery cell 21 along its length direction is the side face 211 of the battery cell 21. As an example, the length direction of the battery cell 21 may be perpendicular to the first direction M, and in this case, the side face 211 of the battery cell 21 is parallel to the first direction M.

[0108] In some embodiments, the housing 10 includes a limiting beam 13, which is installed inside the housing 10 to increase the structural strength of the housing 10 and can also be used to support the battery cell 21 to limit the expansion deformation of the battery cell 21.

[0109] In some embodiments, the housing 10 includes a mounting beam 14, which is fixedly connected to the frame 111 and is used to connect an external device using the battery device 100 to support the battery device 100 on the device.

[0110] Please see Figures 1 to 9 According to some embodiments of this application, an adhesive applicator 300 is provided, including a tray 30, a conveyor line 40, and an adhesive applicator 50. The tray 30 is used to support a battery cell assembly 20, which includes a plurality of battery cells 21 arranged along a first direction M. The side surfaces 211 of the plurality of battery cells 21 along a second direction N form a side surface 201 of the battery cell assembly 20. The tray 30 is provided with an opening 301 for exposing the side surface 201. The first direction M is perpendicular to the second direction N. The conveyor line 40 is used to convey the tray 30 supporting the battery cell assembly 20 along the first direction M. The adhesive applicator 50 is disposed on one side of the conveyor line 40 and is used to drive the tape roll 91 to release the tape 92 and apply the released tape 92 to the side surface 201 of the battery cell assembly 20 on the tray 30.

[0111] The tray 30 refers to a structure with internal space to accommodate and support the battery cell assembly 20. The tray 30 can be a structure formed by combining multiple plates. The tray 30 can also be a box-shaped structure formed by casting or forging. The tray 30 can be made of metal materials such as aluminum alloy, steel, and iron, or it can be made of materials such as plastic and ceramic.

[0112] Conveyor line 40 refers to a mechanical device used to transport tray 30 and the battery cell assembly 20 supported on it. As an example, conveyor line 40 can be a belt conveyor, which uses a belt to support tray 30 and the battery cell assembly 20, and drives the belt to move, thereby transporting the battery cell assembly 20. As an example, conveyor line 40 can be a chain conveyor, which uses a chain to support tray 30 and the battery cell assembly 20, and drives the chain to move, thereby transporting the battery cell assembly 20. As an example, conveyor line 40 can be a roller conveyor, which uses multiple rollers arranged side-by-side, which cooperate to support tray 30 and the battery cell assembly 20, and drive the rollers to rotate, thereby transporting the battery cell assembly 20.

[0113] The adhesive applicator 50 refers to the structure used to attach the tape 92 to the side 211 of the battery cell 21.

[0114] The battery cell assembly 20 includes a plurality of battery cells 21 arranged along the first direction M, meaning that the battery cell assembly 20 includes a plurality of battery cells 21, and the plurality of battery cells 21 are arranged in a group along the first direction M.

[0115] "Multiple" refers to two or more items.

[0116] The side 211 of the battery cell 21 along the second direction N refers to the surface of the side 211 located at the end of the battery cell 21 along the second direction N.

[0117] The side surface 201 of the battery cell assembly 20 formed by the side surface 211 of the multiple battery cells 21 along the second direction N means that the multiple battery cells 21 are arranged in a group and the side surface 211 of the multiple battery cells 21 on the same side of the second direction N together form the side surface 201 of the battery cell assembly 20.

[0118] The second direction N refers to the direction in which the multiple battery cells 21 in the battery cell assembly 20 are arranged perpendicularly.

[0119] Opening 301 refers to a notch or window structure provided on the tray 30. By providing opening 301 on the tray 30, after the battery cell assembly 20 is placed in the tray 30, the side surface 201 of the battery cell assembly 20 can be exposed through opening 301 so that adhesive can be applied to the side surface 201 of the battery cell assembly 20 from opening 301.

[0120] The adhesive applicator 50 is located on one side of the conveyor line 40, meaning that the adhesive applicator 50 is located on one side of the conveyor line 40 in the conveying direction, so that when the conveyor line 40 is conveying the tray 30 supporting the battery cell assembly 20, the adhesive applicator 50 can apply the tape 92 to the side surface 201 of the battery cell assembly 20.

[0121] The tape roll 91 refers to the roll of tape 92, or the tape 92 wound into a roll to form the tape roll 91.

[0122] Since the tape roll 91 is formed by winding the tape 92, the tape 92 on the tape roll 91 can be pulled out to release the tape 92.

[0123] The adhesive applicator 50 drives the tape roll 91 to release the tape 92, which can reduce the feeding time of the tape 92.

[0124] The adhesive applicator 50 is located on one side of the conveyor line 40. Multiple battery cells 21 are arranged along the first direction M to form a battery cell assembly 20 and placed on a tray 30, so that the side surface 201 of the battery cell assembly 20 is exposed from the opening 301 of the tray 30. The conveyor line 40 drives the tray 30 and the battery cell assembly 20 on it to move along the first direction M and pass through the adhesive applicator 50. The adhesive applicator 50 releases the adhesive tape 92 and can apply the adhesive tape 92 to the side surface 201 of the battery cell assembly 20. This can achieve the application of adhesive tape 92 to the side surface 211 of multiple battery cells 21 at one time, which is highly efficient.

[0125] In the technical solution of this application embodiment, by providing an opening 301 on one side of the tray 30 to expose the side surface 201 of the battery cell assembly 20, and providing an adhesive applicator 50 on one side of the conveyor line 40, the adhesive applicator 50 can release the tape roll 91 and apply the tape 92 to the side surface 201 of the battery cell assembly 20 during the process of the conveyor line 40 driving the tray 30 supporting the battery cell assembly 20 through the adhesive applicator 50. This allows the adhesive applicator 50 to apply the tape 92 to the side surface 211 of each battery cell 21 of the battery cell assembly 20 in one go, resulting in high adhesive applicator efficiency.

[0126] In some embodiments, please refer to Figure 2 , Figures 7 to 9 The tray 30 includes a tray plate 31, two clamping seats 32, and a base plate 33. The tray plate 31 is used to support the battery cell assembly 20. The two clamping seats 32 are respectively disposed at both ends of the tray plate 31 along the first direction M, and the two clamping seats 32 are used to cooperate in clamping the battery cell assembly 20. The base plate 33 is disposed on one side of the tray plate 31 along the second direction N, and the base plate 33 is used to position the battery cell assembly 20 on one side along the second direction N. Along the second direction N, an opening 301 is formed between the other side of the tray plate 31 and the clamping seats 32.

[0127] The pallet 31 refers to the plate structure that serves as the bottom support for the tray 30. The weight of all components of the tray 30 and the battery cell assembly 20 mounted on the tray 30 ultimately acts on the pallet 31. In application, the pallet 31 is placed on the conveyor line 40, meaning the entire tray 30 is placed on the conveyor line 40. The pallet 31 can be made of metals such as steel or aluminum alloy, or high-strength plastics.

[0128] The clamping base 32 refers to the seat structure used to clamp the battery cell assembly 20. The clamping base 32 can be made of metals such as steel and aluminum alloy, or it can be made of materials such as high-strength plastic. The clamping base 32 can be plate-shaped, block-shaped, or other shapes.

[0129] The clamping seat 32 is mounted on the tray 31 so that the tray 31 supports the clamping seat 32.

[0130] Two clamping seats 32 are provided and are respectively located at both ends of the tray 31 along the first direction M, so that the battery cell assembly 20 is placed on the tray 31 and located between the two clamping seats 32. Force can be applied to the battery cell assembly 20 supported on the tray 31 to clamp and fix the battery cell assembly 20 so that the tray 31 can drive the battery cell assembly 20 to move.

[0131] The substrate 33 refers to the plate structure used as a positioning reference for the battery cell 21. The substrate 33 can be made of metals such as steel and aluminum alloy, or it can be made of materials such as high-strength plastics.

[0132] The substrate 33 being disposed on one side of the tray 31 along the second direction N means that the substrate 33 is disposed on one side of the tray 31 along the second direction N. Thus, when the battery cell 21 is placed on the tray 31, the end face of the battery cell 21 along the second direction N can be held against the substrate 33, thereby positioning the position of the battery cell 21 on the tray 31 along the second direction N. This allows for positioning of the position of each battery cell 21 in the battery cell assembly 20 along the second direction N, and positioning of the battery cell assembly 20 as a whole along the second direction N.

[0133] Two clamping seats 32 are located at both ends of the tray 31 along the first direction M, while the substrate 33 is located on one side of the tray 31 along the second direction N. The tray 31, the two clamping seats 32, and the substrate 33 can form a space for accommodating the battery cell assembly 20. The top of this space is open, and the other side of the space along the second direction N is also open. This allows the battery cell assembly 20 to be placed in this space, supporting the battery cell assembly 20 on the tray 31, and allowing the substrate 33 to support each battery cell in the battery cell assembly 20. Positioning is performed by 21, and the battery cell assembly 20 is clamped and fixed by clamping seat 32. The opening on the other side of the space along the second direction N can form an opening 301 on the tray 30. That is, the tray 31 forms an opening 301 between the other side of the second direction N and the two clamping seats 32 to expose the side surface 201 of the battery cell assembly 20. In other words, the side surface 211 of each battery cell 21 in the battery cell assembly 20 can be exposed so that the adhesive applicator 50 can apply adhesive to the side surface 201 of the battery cell assembly 20 from the opening 301.

[0134] Through the above technical solution, a tray 31 is set to support the battery cell assembly 20, and clamping seats 32 are respectively set at both ends of the tray 31 to clamp and fix the battery cell assembly 20 on the tray 31 so that the conveyor line 40 can transport the battery cell assembly 20 along the first direction M; and a substrate 33 is set on one side of the tray 31 along the second direction N so as to position each battery cell 21 in the battery cell assembly 20 along the second direction N, and then position the battery cell 21 along the other side of the second direction N, so that the side surface 201 of the battery cell assembly 20 is flatter, so that when the conveyor line 40 transports the battery cell assembly 20 along the first direction M, adhesive can be applied to the side surface 201 of the battery cell assembly 20.

[0135] In some embodiments, the tray 30 may also be provided with a box structure that is open on one side and at the top along the second direction N, so as to facilitate processing and manufacturing.

[0136] In some embodiments, please refer to Figure 2 , Figures 7 to 9 The substrate 33 is movably mounted on the tray 31. The tray 30 includes a pushing component 34 for driving the substrate 33 to move along the second direction N. The pushing component 34 is mounted on the tray 31.

[0137] The substrate 33 is movably mounted on the tray 31, meaning that the substrate 33 can move on the tray 31.

[0138] The pushing component 34 is a component that can drive the substrate 33 to move along the second direction N. The pushing component 34 can be a linear module such as a cylinder, linear motor, or lead screw and nut assembly. The specific structure of the linear module is as described in the above embodiment and will not be repeated here. The pushing component 34 is mounted on the support plate 31, which supports the pushing component 34. The substrate 33 can be mounted on the pushing component 34, which supports the substrate 33. Of course, the substrate 33 can also be slidably mounted on the support plate 31, which directly supports the substrate 33, so that the pushing component 34 can flexibly push the substrate 33 to move on the support plate 31.

[0139] Through the above technical solution, the pushing component 34 drives the substrate 33 along the second direction N to push the side surface 201 of the battery cell assembly 20 toward the opening 301 of the tray 30, so as to facilitate the application of adhesive to the side surface 201 of the battery cell assembly 20.

[0140] In some embodiments, please refer to Figure 2 , Figures 7 to 9 The tray 30 includes a support plate 35 for carrying the battery cell assembly 20, and the support plate 35 is slidably mounted on the tray 31 along the second direction N.

[0141] The support plate 35 refers to the plate used to directly support the battery cell 21. The support plate 35 can be made of metals such as steel and aluminum alloy, or it can be made of materials such as high-strength plastics.

[0142] The bearing plate 35 is slidably mounted on the support plate 31 along the second direction N, which means that the bearing plate 35 is mounted on the support plate 31 and the bearing plate 35 can slide along the second direction N on the support plate 31, thereby supporting the bearing plate 35 through the support plate 31.

[0143] Through the above technical solution, a support plate 35 is set to movably support the battery cell assembly 20 on the tray 31, and the battery cell assembly 20 is pushed along the second direction N in the direction of pushing the battery cell assembly 20 towards the opening 301 of the tray 30.

[0144] In some embodiments, the battery cell 21 may be directly supported on the tray 31 to simplify the structure of the tray 30.

[0145] In some embodiments, please refer to Figure 2 , Figures 7 to 9 The pallet 30 includes a guide assembly 36 for guiding the carrier plate 35 to move along a second direction N. The guide assembly 36 is mounted on the pallet 31, and the carrier plate 35 is mounted on the guide assembly 36.

[0146] The guide component 36 is a structure used to guide the support plate 35 to slide on the support plate 31. The specific structure of the guide component 36 can be as described in the above embodiments, and will not be repeated here.

[0147] By using the above technical solution, the guide component 36 can be set up so that the support plate 35 can be slidably supported on the tray 31 along the second direction N, so that the substrate 33 can push the battery cell assembly 20 to move along the second direction N, so as to push the side surface 201 of the battery cell assembly 20 toward the opening 301 of the tray 30.

[0148] In some embodiments, a groove extending along the second direction N can be provided on the tray 31, and a slider can be provided on the support plate 35. The slider is placed in the groove to enable the support plate 35 to be slidably mounted on the tray 31 and to guide the support plate 35 to move along the second direction N.

[0149] In some embodiments, please refer to Figure 2 , Figures 7 to 9 A support block 37 can be provided on the support plate 31. The support plate 35 slides on the support block 37 to stabilize the support plate 35, facilitate stable support of the battery cell assembly 20 by the support plate 35, and reduce deformation of the support plate 35. The support block 37 is a block-shaped component used to support the support plate 35. The support block 37 can be made of metals such as steel and aluminum alloy, or high-strength plastics.

[0150] In some embodiments, please refer to Figure 2 , Figures 7 to 9 When the support block 37 and guide component 36 are provided on the support plate 31, the top surface of the support block 37 can be set to be flush with the top of the guide component 36 so as to support the support plate 35 through the support block 37, while the guide component 36 guides the support plate 35 to slide along the second direction N, so as to reduce the force of the support plate 35 on the guide component 36, so that the guide component 36 can flexibly guide the support plate 35 to slide along the second direction N.

[0151] In some embodiments, please refer to Figure 2 , Figures 7 to 9 At least one clamping seat 32 is equipped with a pressing mechanism 38; the pressing mechanism 38 includes a pressure plate 381 for pushing the battery cell assembly 20 and a pushing component 382 for driving the pressure plate 381 to move along a first direction M. The pressure plate 381 is located between two clamping seats 32, and the pushing component 382 is installed on the corresponding clamping seat 32.

[0152] The phrase "at least one clamping seat 32 is equipped with a pressing mechanism 38" means that one of the two clamping seats 32 is equipped with a pressing mechanism 38, or that both clamping seats 32 are equipped with a pressing mechanism 38.

[0153] The pressure plate 381 refers to the plate structure used to press against the end face of the battery cell assembly 20. The pressure plate 381 can be made of metals such as steel and aluminum alloy, or it can be made of materials such as high-strength plastics.

[0154] The pushing assembly 382 refers to the assembly that can drive the pressure plate 381 to move along the first direction M. The pushing assembly 382 can be a linear module such as a cylinder, linear motor, or lead screw and nut assembly. The specific structure of the linear module is as described in the above embodiment and will not be repeated here. The pushing assembly 382 is mounted on the corresponding clamping seat 32, which supports the pushing assembly 382. The pressure plate 381 can be mounted on the pushing assembly 382, ​​which supports the pressure plate 381. Of course, the pressure plate 381 can also be slidably mounted on the support plate 31, which directly supports the pressure plate 381, so that the pushing assembly 382 can flexibly push the pressure plate 381 to move on the support plate 31.

[0155] The pressing mechanism 38 uses a pushing component 382 and a pressure plate 381, which has a simple structure. The pushing component 382 pushes the pressure plate 381 to move along the first direction M. Thus, when the battery cell assembly 20 is supported on the support plate 31, the pushing component 382 pushes the pressure plate 381, causing the pressure plate 381 to press against the battery cell assembly 20. When the pressing mechanism 38 is provided on one clamping seat 32, the pressure plate 381 cooperates with the other clamping seat 32 to clamp and fix the battery cell assembly 20. When the pressing mechanism 38 is provided on two clamping seats 32 respectively, the corresponding pressure plates 381 of the two clamping seats 32 cooperate to clamp and fix the battery cell assembly 20.

[0156] With the above technical solution, the battery cell assembly 20 is placed on the tray 31, and the pusher assembly 382 pushes the pressure plate 381 along the first direction M to press the end of the battery cell assembly 20, thereby clamping and fixing the battery cell assembly 20 so that the tray 30 supports the battery cell assembly 20 and the tray 30 drives the battery cell assembly 20 to move along the first direction M so as to apply adhesive to the side surface 201 of the battery cell assembly 20.

[0157] In some embodiments, when an adhesive layer is provided between two adjacent battery cells 21 in the battery cell assembly 20, the end of the battery cell assembly 20 is held by a pressing mechanism 38 so that the adhesive layer can better bond and fix the adjacent battery cells 21. An adhesive layer is a structural layer that can bond two adjacent objects; it can be made using double-sided tape or liquid adhesives such as structural adhesive.

[0158] In some embodiments, when a buffer layer is provided between two adjacent battery cells 21 in the battery cell assembly 20, the battery cell assembly 20 can be better secured by the pressing mechanism 38 pressing against the end of the battery cell assembly 20.

[0159] In some embodiments, where the tray 30 does not have a pressing mechanism 38, but a buffer layer is provided between two adjacent battery cells 21 in the battery cell assembly 20, the battery cell assembly 20 can be compressed and placed on the tray 31. The rebound of the buffer layer causes both ends of the battery cell assembly 20 to abut against the two clamping seats 32, thereby clamping and fixing the battery cell assembly 20. The buffer layer refers to a sheet or plate-like structure made of an elastic material. The elastic material can be made of materials such as rubber or silicone.

[0160] In some embodiments, please refer to Figures 2 to 4 ,as well as Figure 6 and Figure 7The conveyor line 40 includes a support 41, a conveyor belt 42, a drive shaft 431, a driven shaft 432, and a drive mechanism 44.

[0165] The drive mechanism 44 refers to a mechanism that can drive the drive shaft 431 to rotate. As an example, the drive mechanism 44 can be a motor, which drives the drive shaft 431 to rotate. As an example, the drive mechanism 44 can include a motor and a transmission assembly, with the motor connected to the drive shaft 431 via the transmission assembly, so that the motor drives the drive shaft 431 to rotate via the transmission assembly. As an example, the drive mechanism 44 can be a transmission assembly, which connects to an external rotational source to drive the drive shaft 431 to rotate. The transmission assembly can be a gear set, belt drive assembly, chain drive assembly, etc.

[0166] The cooperation of the drive shaft 431 and the driven shaft 432 to open the conveyor belt 42 means that the drive shaft 431 and the driven shaft 432 extend into the conveyor belt 42, and the drive shaft 431 and the driven shaft 432 tension and expand the conveyor belt 42 so that the conveyor belt 42 can support the tray 30 and the battery cell assembly 20 on it, and the drive shaft 431 can drive the conveyor belt 42 to move.

[0167] In some embodiments, a driven shaft 432 may be provided and cooperate with the drive shaft 431 to support the conveyor belt 42 and tension the conveyor belt 42.

[0168] In some embodiments, multiple driven shafts 432 can be provided to cooperate with the drive shaft 431 to support the conveyor belt 42, tension the conveyor belt 42, and enable the conveyor belt 42 to support the tray 30 more smoothly.

[0169] The drive mechanism 44 is mounted on the bracket 41 so that the bracket 41 supports the drive mechanism 44 so that the drive mechanism 44 can connect to the drive shaft 431 and drive the drive shaft 431 to rotate.

[0170] The connection between the drive mechanism 44 and the drive shaft 431 means that the drive mechanism 44 and the drive shaft 431 can be directly connected or indirectly connected by a coupling or other structure, so that the drive mechanism 44 can drive the drive shaft 431 to rotate.

[0171] The rotational movement of the conveyor belt 42 along the first direction M means that the portion of the conveyor belt 42 above the drive shaft 431 and driven shaft 432 moves in the positive direction along the first direction M, while the portion of the conveyor belt 42 below the drive shaft 431 and driven shaft 432 moves in the opposite direction along the first direction M.

[0172] The portion of the conveyor belt 42 located above the drive shaft 431 and the driven shaft 432 refers to the section of the conveyor belt 42 located above the drive shaft 431 and the driven shaft 432 along the height direction Z.

[0173] The drive mechanism 44 is used to drive the drive shaft 431 to rotate, thereby driving the conveyor belt 42 to rotate and move along the first direction M, thereby driving the tray 30 and the battery cell assembly 20 on it to move along the first direction M, so that the battery cell assembly 20 passes through the adhesive applicator 50, so that the adhesive applicator 50 applies adhesive tape 92 to the side surface 201 of the battery cell assembly 20.

[0174] Through the above technical solution, the drive mechanism 44 drives the drive shaft 431 to rotate, thereby driving the conveyor belt 42 to rotate and move along the first direction M. Thus, when the tray 30 supporting the battery cell assembly 20 is placed on the conveyor belt 42, the tray 30 and the battery cell assembly 20 can be moved along the first direction M by the conveyor belt 42 so as to apply adhesive to the battery cell assembly 20.

[0175] In some embodiments, please refer to Figures 2 to 4 ,as well as Figure 6 and Figure 7 The conveyor belt 42 includes at least two conveyor chains 421 spaced apart along the second direction N. The at least two conveyor chains 421 cooperate to support the tray 30. The drive shaft 431 and the driven shaft 432 are respectively equipped with sprockets 433 that connect to each conveyor chain 421.

[0176] A conveyor chain 421 refers to a loop-shaped structural component made of chain. A chain is an assembly of several rigid components connected by hinges, used to transmit motion and power. Structurally, a chain generally consists of links, pins, rollers, etc., with adjacent links hinged by pins to form a flexible, rotatable connection.

[0177] The conveyor belt 42 includes at least two conveyor chains 421 spaced apart along the second direction N, meaning that two or more conveyor chains 421 are spaced apart along the second direction N to jointly form the conveyor belt 42. At least two conveyor chains 421 are provided to cooperate in supporting the pallet 30, thereby providing more stable support for the pallet 30 and driving the pallet 30 to move along the first direction M.

[0178] A sprocket 433 refers to a structure with teeth on its circumference. The teeth on the sprocket 433 mesh with the chain links, driving the chain to move and transmitting power and motion. Sprockets 433 can be made of materials such as metal, ceramic, and plastic.

[0179] Sprockets 433 are installed on the drive shaft 431 and the driven shaft 432 respectively, so as to connect with the conveyor chain 421 and support the conveyor chain 421. The drive shaft 431 rotates to drive the sprocket 433 on it to rotate, thereby pulling the conveyor chain 421 to rotate.

[0180] Through the above technical solution, at least two conveyor chains 421 are arranged at intervals along the second direction N to stably support the tray 30 and drive the tray 30 and the battery cell assembly 20 on it to move stably along the first direction M. Sprockets 433 are arranged on the drive shaft 431 and the driven shaft 432 to engage with the conveyor chains 421 to support and drive the conveyor chains 421 to rotate along the first direction M. Moreover, by using the conveyor chains 421 and the sprockets 433, the movement position of the conveyor chains 421 along the first direction M can be easily controlled, thereby effectively controlling the movement position of the battery cell assembly 20 along the first direction M to accurately apply adhesive to the side surface 201 of the battery cell assembly 20.

[0194] Through the above technical solution, the positioning module 45 uses the positioning component 451, and the tray 30 moves on the conveyor belt 42. When an error occurs in the adhesive application process, the conveyor line 40 moves the tray 30 and the battery cell assembly 20 on it. When the sensor 4511 detects the movement, it can be determined that the tray 30 has moved to the set position. The first linear module 4513 drives the top actuator 4512 to rise to support the tray 30, thereby stopping the tray 30 for easy maintenance.

[0200] The second linear module 4522 is mounted on the bracket 41 so that the bracket 41 supports the second linear module 4522.

[0201] Through the above technical solution, the positioning module 45 uses the limiting component 452. If a problem occurs during the adhesive application process, the second linear module 4522 drives the stop component 4521 to rise, thereby blocking the pallet 30 being conveyed on the conveyor belt 42 and pausing the pallet 30 for maintenance.

[0202] In some embodiments, please refer to Figures 2 to 4 ,as well as Figure 6 and Figure 7 The positioning module 45 includes a positioning component 451 and a limiting component 452.

[0206] The detection module 60 is a module used to detect the position of the battery cell assembly 20 in the tray 30 on the conveyor line 40.

[0207] The above technical solution uses a detection module 60 to determine the position of the battery cell assembly 20 on the tray 30 so as to accurately apply the tape 92 to the side surface 201 of the battery cell assembly 20.

[0208] In some embodiments, please refer to Figures 2 to 4 The detection module 60 includes a ranging sensor 61, which is used to detect the position of the battery cell assembly 20 along the first direction M. The ranging sensor 61 is provided on at least one side of the transmission line 40 along the second direction N.

[0209] The distance sensor 61 is a sensor used to detect the distance to an object. As an example, the distance sensor 61 can be a laser sensor. As an example, the distance sensor 61 can also be an ultrasonic sensor.

[0210] The distance sensor 61 is used to detect the position of the battery cell assembly 20 along the first direction M. This means that the battery cell assembly 20 moves along the first direction M, passes through the distance sensor 61, and is thus detected by the distance sensor 61, thereby determining the position of the battery cell assembly 20 along the first direction M.

[0211] The provision of a ranging sensor 61 on at least one side of the conveyor line 40 along the second direction N means that the conveyor line 40 is provided with a ranging sensor 61 on one side along the second direction N, or that the conveyor line 40 is provided with a ranging sensor 61 on both sides along the second direction N.

[0212] A ranging sensor 61 is provided on one side of the conveyor line 40 along the second direction N to detect the movement position of the battery cell assembly 20 on the conveyor line 40 along the first direction M.

[0213] Distance sensors 61 are respectively installed on both sides of the conveyor line 40 along the second direction N, so as to detect the movement position of the battery cell assembly 20 on the conveyor line 40 along the first direction M through the distance sensors 61 on both sides of the conveyor line 40, so as to detect more accurately.

[0214] Through the above technical solution, the detection module 60 uses the distance sensor 61 to easily detect the starting position of the battery cell assembly 20 on the tray 30, so as to accurately attach the tape 92 to the side surface 201 of the battery cell assembly 20.

[0215] In some embodiments, please refer to Figures 2 to 4 The detection module 60 includes a vision sensor 62, which is used to identify the shape of the side surface 201 of the battery cell assembly 20 in order to determine the adhesive application position of the side surface 201. The vision sensor 62 is located on the side of the conveyor line 40 where the opening 301 is located.

[0216] A vision sensor 62 is a device that converts visual information from the outside world (such as light, object shape, color, texture, etc.) into electrical signals that can be processed by a computer or electronic system. The vision sensor 62 collects light signals from the environment through optical elements (such as lenses, filters, etc.), and then the photosensitive elements (such as charge-coupled devices, complementary metal-oxide-semiconductor devices, etc.) convert the light signals into electrical signals. After analog-to-digital conversion, signal processing, and other steps, it finally outputs a digital image or related visual data. The vision sensor 62 can use devices such as cameras. A charge-coupled device (CCD) is a semiconductor optoelectronic device whose core function is to convert light signals into electrical signals. It consists of a large number of closely packed photosensitive units (pixels), each of which can convert the amount of light incident on it into a corresponding amount of charge. Complementary metal-oxide-semiconductor (CMOS) is an integrated circuit manufacturing technology that integrates P-type metal-oxide-semiconductor field-effect transistors (PMOS) and N-type metal-oxide-semiconductor field-effect transistors (NMOS) in a complementary manner on the same silicon wafer.

[0217] A vision sensor 62 is located on the side of the conveyor line 40 where the opening 301 is located, so that the vision sensor 62 can capture the shape of the side surface 201 of the battery cell assembly 20 from the opening 301 of the tray 30, thereby determining the adhesive application position on the side surface 201.

[0218] Through the above technical solution, the detection module 60 uses a vision sensor 62 to identify the shape and position of the side surface 201 of the battery cell assembly 20 so as to accurately attach the tape 92 to the side surface 201 of the battery cell assembly 20.

[0219] In some embodiments, the detection module 60 may include only the ranging sensor 61. In some embodiments, the detection module 60 may include only the vision sensor 62.

[0220] In some embodiments, please refer to Figures 2 to 4 The detection module 60 may include a ranging sensor 61 and a vision sensor 62. The ranging sensor 61 detects the position of the battery cell assembly 20, and the vision sensor 62 captures the shape and position of the side surface 201 of the battery cell assembly 20, so as to accurately attach the tape 92 to the side surface 201 of the battery cell assembly 20.

[0221] In some embodiments, please refer to Figures 2 to 5The adhesive applicator 50 includes a feeding module 51, an applicating module 52, and a receiving module 53. The feeding module 51 supports the tape roll 91 and drives the tape 92 to feed and release the tape 92. The applicating module 52 includes a pressure head 521 for applicating the tape 92 released by the feeding module 51 to the side surface 201. The pressure head 521 is provided with a flexible buffer pad 522 for elastically resisting the side surface 201. The receiving module 53 is used to collect the protective layer 93 on the tape 92.

[0222] The feeding module 51 refers to a module that can support the tape roll 91 and release the tape 92 from the tape roll 91.

[0223] As an example, the feeding module 51 may include a feeding shaft 511 to support the tape roll 91. When the bonding module 52 bonds the tape 92, the tape 92 can be pulled to rotate the tape roll 91, thereby releasing the tape 92. The feeding shaft 511 is a shaft that supports the tape roll 91 and drives the tape roll 91. As an example, one feeding shaft 511 can be used and inserted into the center of the tape roll 91 to support the tape roll 91. As an example, multiple feeding shafts 511 can be used, spaced apart, to support the lower periphery of the tape roll 91.

[0224] As an example, the feeding module 51 includes a feeding shaft 511, which can be actively driven to rotate by a structure such as a motor or rotary cylinder to release the tape 92.

[0225] As an example, the feeding module 51 may include a feeding pivot 511 and a guide shaft 512. The guide shaft 512 guides the tape 92 on the tape roll 91 to the bonding module 52. When the bonding module 52 bonds the tape 92, the tape 92 can be pulled to release it and guide the protective layer 93 on the tape 92 to the take-up module 53. The guide shaft 512 better guides the tape 92 to the bonding module 52. The guide shaft 512 refers to a pivot structure used to allow the tape 92 to pass around and guide its position.

[0226] As an example, the feeding module 51 may include a feeding shaft 511, a tension adjusting component 513, and a guide shaft 512. The tension adjusting component 513 is a device used to hold the tape 92 to adjust the tension of the released tape 92. As an example, the tension adjusting component 513 may use a structure combining a frame and a shaft, with the frame supporting the shaft and the frame elastically mounted on a support medium so that the shaft holds the tape 92, thereby adjusting the tension of the tape 92. As an example, an elastic telescopic rod may be used to support the shaft, providing elasticity so that the shaft holds the tape 92, thereby adjusting the tension of the tape 92.

[0227] The pressure head 521 refers to a structure used to press the tape 92 against the side surface 201 of the battery cell assembly 20. As an example, the pressure head 521 can be a flexible plate or block. The pressure head 521 can be made of materials such as rubber or silicone to give it good elasticity. As an example, the pressure head 521 can be a plate or block made of a rigid material. The pressure head 521 can be made of metal materials such as aluminum alloy, steel, or iron, or plastic to give it good rigidity.

[0228] Flexible cushioning pad 522 refers to a sheet or strip with elasticity. Flexible cushioning pad 522 can be made of elastic materials such as rubber or silicone.

[0229] The bonding module 52 uses a pressure head 521 to adhere the tape 92 to the side surface 201 of the battery cell assembly 20. A flexible buffer pad 522 is provided on the pressure head 521 to provide elastic cushioning for adhering the tape 92 to the side surface 201 of the battery cell assembly 20, and to reduce the risk of scratching the side surface 211 of the battery cell 21.

[0230] The receiving module 53 refers to the structure used to collect the protective layer 93 torn from the tape 92. As an example, the receiving module 53 may include a receiving shaft 531 to support the roll of protective layer 93. Alternatively, a rotary cylinder, motor, or other structure can be used to drive the receiving shaft 531 to rotate, thereby rotating the roll of protective layer 93 and pulling it to collect the protective layer 93. As an example, the receiving module 53 may also use a robotic arm to pull the protective layer 93 to a designated position, such as a recycling bin. Since the tape 92 is generally double-sided adhesive and the raw material of the tape 92 is a rolled material, a protective layer 93, such as release paper, is usually attached to the tape 92. After the tape 92 is attached to the side 211 of the battery cell 21, the protective layer 93 needs to be peeled off.

[0231] Through the above technical solution, a feeding module 51 is set to release the tape 92. The tape 92 passes through the pressure head 521, so that the tape 92 is adhered to the side surface 201 of the battery cell assembly 20 by the pressure head 521. The protective layer 93 on the tape 92 is collected by the receiving module 53 so that the tape 92 can be adhered to the side surface 201 of the battery cell assembly 20. A flexible buffer pad 522 is set on the pressure head 521, which can both press the tape 92 against the side surface 211 of the battery cell 21 and provide elastic buffer space to play a good protective role and reduce the risk of scratching the side surface 211 of the battery cell 21.

[0232] In some embodiments, please refer to Figures 2 to 5 The bonding module 52 may include an adhesive applicator 524, which supports the pressure head 521 so that the pressure head 521 can apply the tape 92 to the side surface 201 of the battery cell assembly 20. The adhesive applicator 524 refers to the frame structure used to support the pressure head 521.

[0233] Of course, in some embodiments, the pressure head 521 can also be mounted on the conveyor line 40, and the conveyor line 40 can support the pressure head 521.

[0234] In some embodiments, please refer to Figures 2 to 5The bonding module 52 may include a pressure adjusting member 523, which adjusts the pressure of the pressure head 521 against the side surface 201 of the battery cell assembly 20, so that the pressure head 521 adheres the tape 92 to the side surface 201 of the battery cell assembly 20. The pressure adjusting member 523 can automatically adjust the bonding pressure according to the dimension of the battery cell assembly 20 along the second direction N, so as to reduce the risk of scratches on the side surface 211 of the battery cell 21 or poor adhesion of the tape 92. As an example, the pressure adjusting member 523 may use a resilient structural member to hold the pressure head 521 against the battery cell assembly 20. As an example, the pressure adjusting member 523 may use a resilient plate to support the pressure head 521 and elastically push the pressure head 521 against the battery cell assembly 20. As an example, the pressure adjusting member 523 may use a resilient telescopic rod to support the pressure head 521 and elastically push the pressure head 521 against the battery cell assembly 20. As an example, the pressure regulating member 523 can use a spring or sheet spring, and the pressure head 521 can be rotatably mounted on the support medium. The spring or sheet spring elastically abuts the pressure head 521 towards the battery cell assembly 20, so that the pressure head 521 elastically abuts the battery cell assembly 20. As an example, the pressure regulating member 523 can also use a linear module, which supports the pressure head 521 and pushes the pressure head 521 against the battery cell assembly 20. The distance the pressure head 521 moves towards the conveyor line 40 can be adjusted by adjusting the linear module, thereby adjusting the force of the pressure head 521 against the battery cell 21.

[0235] In some embodiments, please refer to Figures 2 to 5 The adhesive applicator 50 also includes a support 54, and the feeding module 51, the bonding module 52 and the receiving module 53 can be respectively installed on the support 54.

[0236] Support 54 refers to a base structure used to support an object. As an example, support 54 can be formed by combining plates, rods, blocks, etc. As an example, support 54 can be a one-piece structure, manufactured by methods such as casting, forging, or injection molding.

The bracket 41 has limiting blocks 411 on both sides along the second direction N, which are used to cooperate and limit the opposite sides of the tray 30 to confine the tray 30 onto the conveyor belt 42.

[0242] In the technical solution of this application embodiment, the battery cell assembly 20 is placed on the support plate 35 of the tray 30.
