Description

Technical Field

[0001] This application relates to the field of battery manufacturing technology, specifically to a pressure 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] In the adhesive application process of battery devices, a pressure device is usually used to press the adhesive to ensure that a stable interface is formed after curing. However, different battery device models have different sizes, while the size of the pressure component in the pressure device is fixed. To accommodate battery devices of different sizes, it is time-consuming to replace the pressure component, which is not conducive to improving the production efficiency of battery devices. Utility Model Content

[0004] One of the objectives of this application is to provide a pressure application device and battery manufacturing equipment, which aims to solve the technical problem of poor compatibility of the pressure application components in related technologies.

[0005] To solve the above-mentioned technical problems, the technical solution adopted in this application embodiment is as follows: a pressure device is provided, including a pressure seat, a pressure member, a first driving mechanism, and a second driving mechanism; the pressure seat has a guide structure extending along a first direction; the pressure member is used to press against the component to be pressed, and the pressure member is slidably mounted on the guide structure; the first driving mechanism is used to drive the pressure seat to move along a second direction toward the component to be pressed, so that the pressure member presses against the component to be pressed, the second direction being perpendicular to the first direction; the second driving mechanism is used to drive the pressure member to slide back and forth along the first direction on the guide structure, so that at least a portion of the pressure member enters or leaves the guide structure.

[0006] The beneficial effects of the pressure application device provided in this application embodiment are as follows: The pressure seat in the pressure application device provided in this application embodiment has a guide structure extending along a first direction. The pressure application member is slidably installed on the guide structure. The second driving mechanism can drive the pressure application member to slide back and forth along the first direction on the guide structure, so that at least part of the pressure application member enters or leaves the guide structure. According to the size of the part to be pressed along the first direction, under the driving action of the second driving mechanism, at least part of the pressure application member enters or leaves the guide structure, thereby realizing the adjustment of the size of the pressure application member along the first direction on the guide structure, so that the size of the pressure application member along the first direction can be adapted to the size of the part to be pressed along the first direction. In this way, when applying pressure to parts of different sizes, there is no need to replace the pressure application member, effectively saving the time spent on replacing the pressure application member and effectively improving production efficiency.

[0007] In some embodiments of this application, the pressure-applying component includes multiple pressure-applying units, which are sequentially hinged to form a chain structure. The second driving mechanism is used to drive the pressure-applying component to slide back and forth along a first direction on the guide structure, so as to drive at least some of the multiple pressure-applying units into or out of the guide structure.

[0008] By adopting the above technical solution, it is not only convenient to set the length of the pressure-applying component according to the actual application requirements, so that the pressure-applying component can be adapted to more components of different sizes to be pressed, but also the part of the pressure-applying component outside the guide structure can be bent according to the installation environment, thereby optimizing the overall layout structure of the pressure-applying device and making the overall layout structure of the pressure-applying device more compact.

[0009] In some embodiments of this application, the second driving mechanism includes a turntable and a driver. One end of the pressure-applying member is slidably mounted on the guide structure, and the other end of the pressure-applying member is connected to the turntable. The driver is used to drive the turntable to rotate so as to drive at least some of the multiple pressure-applying units into or out of the guide structure.

[0010] By adopting the above technical solution, it is not only convenient to drive the pressure-applying component to slide back and forth on the guide structure in the first direction, but also to simplify the structure of the second drive mechanism and reduce the space occupied by the second drive mechanism, thereby making the overall layout structure of the pressure-applying device more compact.

[0011] In some embodiments of this application, the pressure-applying unit includes a main body, a first hinge portion, and a second hinge portion. The main body is used for sliding cooperation with the guide structure. The first hinge portion and the second hinge portion are located on opposite sides of the main body. The first hinge portion of one pressure-applying unit is hinged to the second hinge portion of another pressure-applying unit.

[0012] By adopting the above technical solution, it is easy to hinge multiple pressure units in sequence to form a chain structure, which is simple and easy to implement.

[0013] In some embodiments of this application, the first hinge portion and the second hinge portion are offset along a third direction, and the first hinge portion of one pressure unit and the second hinge portion of another pressure unit are abutted against each other along a third direction, which is perpendicular to the first direction and the second direction.

[0014] By adopting the above technical solution, each pressure unit can be mutually limited and coordinated in a third direction, which improves the shaking of the pressure component during the pressure application process, enhances the stability of the pressure application process, and thus improves the pressure application accuracy of the pressure application device.

[0015] In some embodiments of this application, the turntable includes a disc body and a boss protruding from one end face of the disc body. One end of the pressure-applying member is connected to the end face of the disc body facing the boss, and the outer peripheral surface of the boss is used to abut against the pressure-applying member.

[0016] By adopting the above technical solution, the outer peripheral surface of the boss can play a supporting role for the pressure-applying component, thereby better guiding at least some of the multiple pressure-applying units into or out of the guide structure, improving the jamming situation that occurs during the second drive mechanism to drive the pressure-applying component, enhancing the stability during the process of adjusting the size of the pressure-applying component along the first direction, and thus improving the adjustment accuracy of the pressure-applying device.

[0017] In some embodiments of this application, the second drive mechanism further includes a transmission member having a spur tooth portion, the turntable including a disc body and a gear portion, the disc body and the gear portion being connected and coaxially arranged, one end of the pressure member being connected to the disc body, the gear portion and the spur tooth portion meshing with each other, and the driver being used to drive the transmission member to reciprocate along a first direction to drive the turntable to rotate.

[0018] By adopting the above technical solution, the rotation angle of the turntable can be precisely controlled, thereby allowing for precise adjustment of the dimensions of the pressure-applying component along the first direction, thus improving the adjustment accuracy of the pressure-applying device.

[0019] In some embodiments of this application, the pressure-applying member includes a plurality of pressure-applying units arranged in sequence. The second driving mechanism is used to drive the pressure-applying member to slide back and forth on the guide structure in a first direction, so as to drive at least some of the plurality of pressure-applying units into or out of the guide structure. The pressure-applying unit includes a main body, a pressure-applying part, and an elastic member. The main body is used to slide and cooperate with the guide structure. The pressure-applying part is used to press against the component to be pressed. The pressure-applying part is connected to the end of the main body away from the guide structure and can move in a direction closer to or away from the main body. The elastic member abuts against the pressure-applying part and the main body.

[0020] By adopting the above technical solution, the pressure-applying component can adapt to the surface flatness difference of the component to be pressed when applying pressure, reducing the risk of damage to the component to be pressed due to excessive local pressure. At the same time, it can make the overall pressure applied by the pressure-applying component to the component to be pressed more uniform, thereby effectively improving the pressure quality of the pressure-applying device.

[0021] In some embodiments of this application, the pressure seat includes a seat body and a guide member. The guide member is mounted on the seat body and has a guide groove extending along a first direction to form a guide structure.

[0022] By adopting the above technical solution, it is easy to form a guiding structure, which effectively reduces the manufacturing cost of the pressure application device.

[0023] In some embodiments of this application, the pressure-applying member includes a plurality of pressure-applying units arranged in sequence, and the second driving mechanism is used to drive the pressure-applying member to slide back and forth on the guide structure in a first direction, so as to drive at least some of the plurality of pressure-applying units to enter or leave the guide structure. The pressure-applying unit includes a main body portion, which is used to slide and cooperate with the guide structure, and the main body portion abuts against the two opposite groove walls of the guide groove.

[0024] By adopting the above technical solution, the position of each pressure unit can be restricted along the width direction of the guide groove, which improves the shaking of the pressure component during the pressure application process, enhances the stability of the pressure application process, and thus improves the pressure application accuracy of the pressure application device.

[0025] In some embodiments of this application, at least one wall of the guide groove is recessed with a limiting groove extending in a first direction, and the main body is protruding with a limiting part, which is inserted into the limiting groove.

[0026] By adopting the above technical solution, the risk of the pressure unit detaching from the guide groove can be effectively reduced, thereby effectively improving the reliability of the pressure device.

[0027] Secondly, embodiments of this application provide a battery manufacturing apparatus, including the pressure application device described in any of the above embodiments.

[0028] The beneficial effects of the battery manufacturing equipment provided in this application embodiment are as follows: the battery manufacturing equipment provided in this application embodiment effectively saves the changeover time of the pressure device by adopting the pressure device described in any of the above embodiments, thereby effectively improving the production efficiency of the battery device.

[0055] In related technologies, battery devices include a housing and battery cell assemblies. Each battery cell assembly comprises multiple individual battery cells, which are the smallest units where electrochemical reactions occur. The housing houses the battery cell assemblies. After placing the battery cell assemblies inside the housing, a pressure strip is typically installed at the opening of the housing. Both ends of the pressure strip are connected to the housing to press against the battery cell assembly. An adhesive medium is also used between the pressure strip and the battery cell assembly to bond them together, thus limiting the position of the battery cell assembly. To ensure a stable connection between the pressure strip and the battery cell assembly, a pressure-applying device is usually used to apply pressure to the pressure strip.

[0056] However, due to the differences in size between different models of battery devices, the length of the pressure strips used also varies. The size of the pressure-applying component in the pressure-applying device is fixed and cannot be adapted to pressure strips of different sizes. In order to adapt the pressure-applying component to pressure strips of different sizes, time must be spent replacing the pressure-applying component, which is not conducive to improving the production efficiency of battery devices.

[0057] To improve the compatibility of the pressure application device, the pressure base in the pressure application device provided in this application embodiment has a guide structure extending along a first direction. The pressure application member is slidably mounted on the guide structure. The second driving mechanism can drive the pressure application member to slide back and forth along the first direction on the guide structure, so that at least part of the pressure application member enters or leaves the guide structure. According to the size of the part to be pressed along the first direction, under the driving action of the second driving mechanism, at least part of the pressure application member enters or leaves the guide structure, thereby realizing the adjustment of the size of the pressure application member along the first direction on the guide structure, so that the size of the pressure application member along the first direction can be adapted to the size of the part to be pressed along the first direction. In this way, when applying pressure to parts of different sizes, there is no need to replace the pressure application member, effectively saving the time spent on replacing the pressure application member and effectively improving production efficiency.

[0058] The pressure applying device disclosed in this application can be applied to the glue application process of battery devices. For example, the pressure applying device is used to press the pressure strip of the battery device against the glue application process. Of course, the pressure applying device disclosed in this application can also be applied to the production process of other workpieces, and no specific limitation is made here.

[0059] The battery device disclosed in this application can be used in electrical devices that use batteries as a power source or in various energy storage systems that use batteries as energy storage elements. Electrical devices can be, but are not limited to, mobile phones, tablets, laptops, electric toys, power tools, electric vehicles, electric cars, ships, spacecraft, etc. Electric toys can include stationary or mobile electric toys, such as game consoles, electric car toys, electric ship toys, and electric airplane toys, etc. Spacecraft can include airplanes, rockets, space shuttles, and spacecraft, etc.

[0060] Figure 1 This is an exploded structural diagram of the battery device 200 provided in an embodiment of this application. The battery device 200 mentioned in the embodiments of this application may include one or more battery cell assemblies for providing voltage and capacity. The battery cell assembly may include multiple battery cells 202, which are connected in series, parallel, or mixed connection via a busbar.

[0061] In some embodiments, the battery cell assembly is typically formed by arranging a plurality of battery cells 202.

[0062] As an example, the battery cell assembly can be a battery module, which is formed by arranging and fixing multiple battery cells 202 together to form an independent module. As an example, the battery module can be formed by bundling multiple battery cells 202 together with cable ties.

[0063] In some embodiments, the battery device 200 may be a battery pack, which includes a housing 201 and one or more battery cell assemblies, the battery cell assemblies being housed in the housing 201.

[0064] As an example, the battery cell assembly can be a battery module, and the battery cell assembly can be housed in the housing 201 by fixing the battery module in the housing 201.

[0065] As an example, the battery cell assembly can also be housed in the housing 201 by directly fixing multiple battery cells 202 to the housing 201.

[0066] As an example, the housing 201 may include a first housing 2011 and a second housing 2012. The first housing 2011 and the second housing 2012 are fastened together to form a closed space inside the housing 201 to house the battery cell assembly. Here, "closed" refers to covering or closing, which can be sealed or unsealed. The first housing 2011 may be a top cover or a bottom plate.

[0067] As an example, the housing 201 may include a top cover, a frame, and a bottom plate. The top cover and the bottom plate are respectively connected to the frame, so that the interior of the housing 201 forms an enclosed space to accommodate the battery cell assembly.

[0068] In some embodiments, the housing 201 may be part of the vehicle's chassis structure. For example, a portion of the housing 201 may be at least a portion of the vehicle's floor, or a portion of the housing 201 may be at least a portion of the vehicle's crossbeams and longitudinal beams.

[0069] In this embodiment of the application, the battery cell 202 can be a secondary battery. A secondary battery refers to a battery cell 202 that can be used again after being discharged by recharging to activate the active materials.

[0070] The battery cell 202 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.

[0071] A battery cell 202 typically includes an electrode assembly. The electrode assembly includes a positive electrode, a negative electrode, and a separator, with the separator positioned between the negative and positive electrodes. During the charging and discharging process of the battery cell 202, active ions (such as lithium ions) repeatedly insert and extract between the positive and negative electrodes. The separator, positioned between the positive and negative electrodes, prevents short circuits while allowing active ions to pass through.

[0072] The electrode assembly can be a wound structure, a stacked structure, or a hybrid structure of wound and stacked.

[0073] In some implementations, the electrode assembly is a wound structure. The positive and negative electrode sheets are wound into a wound structure.

[0074] In some implementations, the electrode assembly is a stacked structure.

[0075] As an example, multiple positive and negative electrodes can be set, and multiple positive and multiple negative electrodes can be stacked alternately.

[0076] As an example, multiple positive electrode plates can be provided, and negative electrode plates can be folded to form multiple stacked folded sections, with a positive electrode plate sandwiched between adjacent folded sections.

[0077] As an example, both the positive and negative electrode sheets are folded to form multiple stacked folded sections.

[0078] As an example, multiple separators can be provided, each positioned between any adjacent positive or negative electrode plates.

[0079] As an example, the separators can be continuously arranged, either by folding or rolling between any adjacent positive or negative electrode plates.

[0081] In some embodiments, the electrode assembly has tabs that allow current to be drawn from the electrode assembly. The tabs include a positive tab and a negative tab.

[0082] In some embodiments, the battery cell 202 may include a casing. The casing may be a steel casing, an aluminum casing, a plastic casing (such as a polypropylene casing), a composite metal casing (such as a copper-aluminum composite casing), or an aluminum-plastic film, etc. In some embodiments, the casing may be a sealed structure or a non-sealed structure. As an example, when the casing is a non-sealed structure, the casing serves to protect the electrode assembly, and a sealing bag is included between the casing and the electrode assembly to encapsulate the electrode assembly and electrolyte. Specifically, the sealing bag may be a bag-shaped insulating component or an aluminum-plastic film. When the casing is a sealed structure, it is used to encapsulate components such as the electrode assembly and electrolyte.

[0083] As an example, the battery cell 202 can be a cylindrical battery cell, a prismatic battery cell, a pouch battery cell, or a battery cell 202 of other shapes. Prismatic battery cells include prismatic battery cells, blade-shaped battery cells, and multi-prismatic battery cells. Multi-prismatic battery cells are, for example, hexagonal prismatic battery cells. This application does not have any particular limitations.

[0084] In some embodiments, the housing includes an end cap and a housing, the housing having an opening, and the end cap covering the opening. The housing may have one or more openings. The end cap may also be provided one or more.

[0085] In some embodiments, at least one electrode terminal is provided on the housing, and the electrode terminal is electrically connected to the tab. The electrode terminal can be directly connected to the tab, or it can be indirectly connected to the tab through a current collector. The electrode terminal can be provided on the end cap or on the housing.

[0086] In some embodiments, the electrode terminals of multiple battery cells 202 are welded to a busbar to achieve electrical connection between the multiple battery cells 202.

[0087] To illustrate the technical solutions provided in this application, the following detailed description is provided in conjunction with specific drawings and embodiments.

[0088] Firstly, please refer to the following: Figure 2 and Figure 3 This application provides a pressure application device 100, including a pressure base 10, a pressure member 20, a first driving mechanism, and a second driving mechanism 30. The pressure base 10 has a guide structure 121 extending along a first direction. The pressure member 20 is used to press against the component to be pressed, and the pressure member 20 is slidably mounted on the guide structure 121. The first driving mechanism is used to drive the pressure base 10 to move along a second direction toward the component to be pressed, so that the pressure member 20 presses against the component to be pressed. The second direction is perpendicular to the first direction. The second driving mechanism 30 is used to drive the pressure member 20 to slide back and forth on the guide structure 121 along the first direction, so that at least a portion of the pressure member 20 enters or leaves the guide structure 121.

[0089] First, it should be noted that the pressure applying device 100 has a first direction, a second direction, and a third direction. For example... Figure 2 and Figure 3 As shown, the first direction can be Figure 2 and Figure 3 The X direction shown is the length direction of the pressure application device 100. The second direction is perpendicular to the first direction, and the second direction can be... Figure 2 and Figure 3 The Z direction shown is the height direction of the pressure application device 100. The third direction is perpendicular to the first and second directions. The third direction can be... Figure 2 and Figure 3 The Y direction shown is the width direction of the pressure application device 100.

[0090] The pressure seat 10 is a component used to support the pressure-applying member 20 and transmit the applied pressure to the pressure-applying member 20. The pressure seat 10 can be a one-piece molded component or a separate component. The material of the pressure seat 10 can be, but is not limited to, aluminum, aluminum alloy, copper, iron, steel, hard plastic, etc.

[0091] The guide structure 121 is a structure used to guide the pressure-applying member 20 to move in a first direction.

[0092] As an example, the guide structure 121 may be a guide groove extending along a first direction.

[0093] As an example, the guide structure 121 can be a guide rail extending along a first direction.

[0094] The pressure-applying component 20 is a component used to directly contact the component to be pressed and apply pressure to the component to be pressed.

[0095] At least a portion of the pressure-applying member 20 is slidably mounted on the guide structure 121 so that the pressure-applying member 20 can reciprocate along a first direction on the guide structure 121. Understandably, the portion of the pressure-applying member 20 on the guide structure 121 is used to apply pressure to the component to be pressed. The dimension of the pressure-applying member 20 along the first direction on the guide structure 121 can be adjusted according to actual application requirements by moving the pressure-applying member 20 along the first direction, so that the dimension of the portion of the pressure-applying member 20 on the guide structure 121 along the first direction can adapt to the dimension of the component to be pressed along the first direction.

[0096] In some embodiments, the pressure-applying member 20 has a strip-like structure, wherein the portion of the pressure-applying member 20 on the guide structure 121 extends along a first direction. The pressure-applying member 20 can be a one-piece molded component or it can be composed of multiple components connected sequentially.

[0097] As an example, the pressure-applying component 20 is composed of multiple parts connected in sequence to form a flexible strip structure, that is, the pressure-applying component 20 can be bent and deformed.

[0098] As an example, the pressure-applying component 20 is a rigid strip-shaped component formed in one piece, that is, the pressure-applying component 20 extends along the first direction as a whole and cannot be bent or deformed.

[0099] The first drive mechanism is used to provide pressure from the pressure-applying member 20 to the component to be pressed. Understandably, the power output end of the first drive mechanism is connected to the pressure seat 10, and the first drive mechanism can drive the pressure seat 10 to reciprocate along a second direction, thereby causing the pressure-applying member 20 to reciprocate along the second direction. During the pressing process, the first drive mechanism drives the pressure seat 10 along the second direction toward the component to be pressed, thereby causing the pressure-applying member 20 to move toward the component to be pressed until the pressure-applying member 20 presses against the component to be pressed.

[0100] In some embodiments, the first drive mechanism is a linear drive mechanism. The first drive mechanism can be, but is not limited to, an electric pneumatic cylinder, an electric hydraulic cylinder, a ball screw drive mechanism, a gear and rack drive mechanism, etc.

[0101] The second drive mechanism 30 is a mechanism for providing power to the pressure member 20 to reciprocate along the first direction on the guide structure 121.

[0102] In some embodiments, the guide structure 121 has a first end and a second end disposed opposite to each other along a first direction, and at least a portion of the pressure member 20 can enter or exit the guide structure 121 via the first end. During the process of the second drive mechanism 30 driving the pressure member 20 to move from the first end to the second end, at least a portion of the pressure member 20 enters the guide structure 121 via the first end; during the process of the second drive mechanism 30 driving the pressure member 20 to move from the second end to the first end, at least a portion of the pressure member 20 exits the guide structure 121 via the first end, thereby achieving adjustment of the dimension of the pressure member 20 along the first direction on the guide structure 121.

[0103] In some embodiments, the pressure device 100 is used to press against the pressure strip in the battery device 200. Specifically, the battery device 200 includes a housing 201, a battery cell assembly, and a pressure strip. The housing 201 is used to house the battery cell assembly. Both ends of the pressure strip are connected to the housing 201 so that the pressure strip presses against the battery cell assembly. An adhesive is provided between the pressure strip and the battery cell assembly. The length direction of the pressure strip is parallel to a first direction. During the pressing process, the pressure member 20 is first driven to move along the first direction according to the length of the pressure strip by the second drive mechanism 30, so as to adjust the size of the pressure member 20 along the first direction on the guide structure 121, so that the size of the part of the pressure member 20 on the guide structure 121 along the first direction can be adapted to the length of the pressure strip. Subsequently, the first drive mechanism drives the pressure seat 10 along the second direction toward the direction closer to the pressure strip, so as to move the pressure member 20 toward the direction closer to the pressure strip, until the pressure member 20 presses against the pressure strip, so as to squeeze the adhesive provided between the pressure strip and the battery cell assembly.

[0104] The pressure base 10 in the pressure device 100 provided in this application embodiment has a guide structure 121 extending along a first direction. The pressure member 20 is slidably mounted on the guide structure 121. The second drive mechanism 30 can drive the pressure member 20 to slide back and forth along the first direction on the guide structure 121, so that at least part of the pressure member 20 enters or leaves the guide structure 121. According to the size of the part to be pressed along the first direction, under the driving action of the second drive mechanism 30, at least part of the pressure member 20 enters or leaves the guide structure 121, thereby realizing the adjustment of the size of the pressure member 20 along the first direction on the guide structure 121, so that the size of the pressure member 20 along the first direction can be adapted to the size of the part to be pressed along the first direction. In this way, when applying pressure to parts of different sizes, there is no need to replace the pressure member 20, effectively saving the time spent on replacing the pressure member 20 and effectively improving production efficiency.

[0105] Please refer to some embodiments of this application as well. Figure 2 and Figure 3The pressure-applying component 20 includes multiple pressure-applying units 21, which are sequentially hinged to form a chain structure. The second driving mechanism 30 is used to drive the pressure-applying component 20 to slide back and forth on the guide structure 121 along a first direction, so as to drive at least some of the multiple pressure-applying units 21 to enter or leave the guide structure 121.

[0106] The chain structure formed by multiple pressure units 21 being hinged in sequence means that multiple pressure units 21 are rotatably connected in sequence, and the rotation axis between two adjacent pressure units 21 is perpendicular to the first direction and the second direction, that is, the rotation axis between two adjacent pressure units 21 is parallel to the third direction.

[0107] Understandably, the chain structure has a beginning and an end. At least the pressure unit 21 at the beginning is slidably mounted on the guide structure 121, and the other pressure units 21 can slide into the guide structure 121 after entering it. The second drive mechanism 30 can provide the pressure unit 21 at the beginning with the power to reciprocate along a first direction on the guide structure 121, thereby driving the other pressure units 21 to enter or leave the guide structure 121.

[0108] In some embodiments, please refer to Figure 4 The pressure unit 21 includes a main body 211, a first hinge 212, and a second hinge 213. The main body 211 is used to slide with the guide structure 121. The first hinge 212 and the second hinge 213 are respectively disposed on opposite sides of the main body 211. The first hinge 212 of one pressure unit 21 is hinged to the second hinge 213 of the other pressure unit 21.

[0109] The main body 211 is the main body 211 position of the pressure unit 21. The main body 211 is used to slide with the guide structure 121 and to provide support for parts of the pressure unit 21 such as the first hinge 212 and the second hinge 213.

[0110] Understandably, along the direction from the beginning to the end of the chain structure, the first hinge portion 212 of the first pressure unit 21 is hinged to the second hinge portion 213 of the second pressure unit 21, the first hinge portion 212 of the second pressure unit 21 is hinged to the second hinge portion 213 of the third pressure unit 21, the first hinge portion 212 of the third pressure unit 21 is hinged to the second hinge portion 213 of the fourth pressure unit 21, and so on, so as to sequentially hinge multiple pressure units 21 to form a chain structure.

[0111] By adopting the above technical solution, it is not only convenient to set the length of the pressure-applying component 20 according to the actual application requirements, so that the pressure-applying component 20 can be adapted to more components of different sizes to be pressed, but also the part of the pressure-applying component 20 located outside the guide structure 121 can be bent according to the installation environment, thereby optimizing the overall layout structure of the pressure-applying device 100 and making the overall layout structure of the pressure-applying device 100 more compact.

[0112] In some embodiments of this application, please refer to Figure 2 The second drive mechanism 30 includes a turntable 31 and a driver 32. One end of the pressure applying member 20 is slidably mounted on the guide structure 121, and the other end of the pressure applying member 20 is connected to the turntable 31. The driver 32 is used to drive the turntable 31 to rotate so that at least some of the multiple pressure applying units 21 enter or leave the guide structure 121.

[0113] Understandably, the turntable 31 is rotatably mounted on the pressure base 10, and the rotation axis of the turntable 31 is perpendicular to the first direction and the second direction, that is, the rotation axis of the turntable 31 is parallel to the third direction.

[0114] In some embodiments, along the direction from the beginning to the end of the chain structure, the first pressure unit 21 is slidably mounted on the guide structure 121, and the last pressure unit 21 is hinged to the turntable 31.

[0115] As an example, the pressure unit 21 includes a main body 211, a first hinge 212, and a second hinge 213. The main body 211 of the first pressure unit 21 is slidably mounted on the guide structure 121. After entering the guide structure 121, the main bodies 211 of the other pressure units 21 can slide and engage with the guide structure 121. Along the direction from the beginning to the end of the chain structure, the first hinge 212 of the first pressure unit 21 is hinged to the second hinge 213 of the second pressure unit 21, the first hinge 212 of the second pressure unit 21 is hinged to the second hinge 213 of the third pressure unit 21, the first hinge 212 of the third pressure unit 21 is hinged to the second hinge 213 of the fourth pressure unit 21, and so on, so that multiple pressure units 21 are sequentially hinged to form a chain structure. The first hinge 212 or the second hinge 213 of the last pressure unit 21 is hinged to the turntable 31.

[0116] The driver 32 is used to provide power for the rotation of the turntable 31.

[0117] In some embodiments, please refer to Figure 3The second drive mechanism 30 also includes a transmission component 33, which has a spur gear portion 331. The turntable 31 includes a disc body 311 and a gear portion 313. The disc body 311 and the gear portion 313 are connected and coaxially arranged. One end of the pressure-applying component 20 is connected to the disc body 311. The gear portion 313 meshes with the spur gear portion 331. The driver 32 is used to drive the transmission component 33 to reciprocate along the first direction, thereby driving the turntable 31 to rotate. This allows for precise control of the rotation angle of the turntable 31, thereby allowing for precise adjustment of the size of the pressure-applying component 20 along the first direction, improving the adjustment accuracy of the pressure-applying device 100.

[0118] Understandably, the transmission component 33 is slidably mounted on the pressure base 10 and can reciprocate along the first direction.

[0119] As an example, the actuator 32 can be, but is not limited to, an electric pneumatic cylinder, an electric hydraulic cylinder, etc.

[0120] Of course, in other embodiments, the transmission component 33 may be omitted, and instead, the driver 32 may be directly connected to the turntable 31 to drive the turntable 31 to rotate. As an example, the driver 32 may be, but is not limited to, a stepper motor, a servo motor, etc.

[0121] By adopting the above technical solution, it is not only convenient to drive the pressure-applying component 20 to slide back and forth on the guide structure 121 along the first direction, but also to simplify the structure of the second drive mechanism 30 and reduce the space occupied by the second drive mechanism 30, thereby making the overall layout structure of the pressure-applying device 100 more compact.

[0122] In some embodiments of this application, please refer to Figure 4 The first hinge portion 212 and the second hinge portion 213 are offset along a third direction. The first hinge portion 212 of one pressure unit 21 and the second hinge portion 213 of another pressure unit 21 are abutted against each other along a third direction, which is perpendicular to the first direction and the second direction.

[0123] Understandably, along the direction from the beginning to the end of the chain structure, the first hinge portion 212 of the first pressure unit 21 and the second hinge portion 213 of the second pressure unit 21 are abutted against each other in a third direction, the first hinge portion 212 of the second pressure unit 21 and the second hinge portion 213 of the third pressure unit 21 are abutted against each other in a third direction, the first hinge portion 212 of the third pressure unit 21 and the second hinge portion 213 of the fourth pressure unit 21 are abutted against each other in a third direction, and so on.

[0124] By adopting the above technical solution, each pressure unit 21 can be mutually limited and coordinated in a third direction, which improves the shaking of the pressure component 20 during the pressure application process, enhances the stability of the pressure application process, and thus improves the pressure application accuracy of the pressure application device 100.

[0125] In some embodiments of this application, please refer to Figure 3 The turntable 31 includes a disc body 311 and a boss 312 protruding from one end face of the disc body 311. One end of the pressure member 20 is connected to the end face of the disc body 311 facing the boss 312. The outer peripheral surface of the boss 312 is used to abut against the pressure member 20.

[0126] In some embodiments, the boss 312 is a frustum, and the boss 312 is coaxially arranged with the disk body 311.

[0127] In some embodiments, along the direction from the beginning to the end of the chain structure, the first pressure unit 21 is slidably mounted on the guide structure 121, and the last pressure unit 21 is hinged to the disc body 311. During the process of the second drive mechanism 30 driving at least some of the pressure units 21 to disengage from the guide structure 121, the boss 312 rotates with the disc body 311 to rewind the pressure member 20. During the process of the second drive mechanism 30 driving at least some of the pressure units 21 to enter the guide structure 121, the boss 312 rotates with the disc body 311 to release the pressure member 20.

[0128] By adopting the above technical solution, the outer peripheral surface of the boss 312 can support the pressure-applying component 20, thereby better guiding at least some of the multiple pressure-applying units 21 into or out of the guide structure 121, improving the situation of jamming during the second drive mechanism 30 driving the pressure-applying component 20, and improving the stability during the process of adjusting the size of the pressure-applying component 20 along the first direction, thereby improving the adjustment accuracy of the pressure-applying device 100.

[0129] Please refer to some embodiments of this application as well. Figure 6 and Figure 8 The pressure unit 21 also includes a pressure part 215 and an elastic member 216. The main body 211 is used to slide with the guide structure 121. The pressure part 215 is used to press against the component to be pressed. The pressure part 215 is connected to the end of the main body 211 away from the guide structure 121 and can move towards or away from the main body 211. The elastic member 216 abuts against the pressure part 215 and the main body 211.

[0130] The pressure-applying part 215 is a part used to directly contact the component to be pressed and apply pressure to the component. The pressure-applying part 215 is connected to the end of the main body 211 away from the guide structure 121 and can move in a direction toward or away from the main body 211.

[0131] The elastic member 216 is a component used to provide an elastic force between the main body 211 and the pressure-applying part 215. Understandably, when the pressure-applying part 215 applies pressure to the component to be pressed, the pressure-applying part 215 moves toward the main body 211, and the elastic member 216 applies an elastic force to the pressure-applying part 215 in the opposite direction to the pressure applied to the component to be pressed. When the pressure-applying part 215 disengages from the component to be pressed, this elastic force pushes the pressure-applying part 215 to move away from the main body 211.

[0132] As an example, the elastic element 216 is a spring, and a guide rod is also provided between the pressure part 215 and the main body 211. The pressure part 215 can move along the length direction of the guide rod towards or away from the main body 211. The elastic element 216 is sleeved on the guide rod, and one end of the elastic element 216 abuts against the main body 211, while the other end of the elastic element 216 abuts against the pressure part 215.

[0133] Of course, in other embodiments, the elastic element 216 may also be other components that can provide elastic force between the main body 211 and the pressure application part 215, such as a spring sheet, an elastic block, etc.

[0134] By adopting the above technical solution, the pressure applying component 20 can adapt to the surface flatness difference of the component to be pressed when applying pressure to the component to be pressed, reducing the risk of damage to the component to be pressed due to excessive local pressure. At the same time, the pressure applying component 20 can make the overall pressure on the component to be pressed more uniform, thereby effectively improving the pressure quality of the pressure applying device 100.

[0135] Please refer to some embodiments of this application as well. Figure 6 and Figure 7 The pressure seat 10 includes a seat body 11 and a guide member 12. The guide member 12 is mounted on the seat body 11 and has a guide groove extending in a first direction to form a guide structure 121.

[0136] The base 11 is the main body 211 of the pressure seat 10, used to provide an installation environment for components such as the guide 12 and the second drive mechanism 30. The guide 12 is a component used to guide the pressure application member 20 to move along the first direction. The base 11 and the guide 12 can be an integrally molded structure, that is, the base 11 and the guide 12 are formed into a whole by using an integral molding process. Alternatively, the base 11 and the guide 12 can be independently molded and then connected to form a whole.

[0137] In some embodiments, please refer to Figure 7The main body 211 abuts against the two opposite walls of the guide groove. This restricts the position of each pressure unit 21 along the width of the guide groove, improves the swaying of the pressure unit 20 during the pressure application process, enhances the stability of the pressure application process, and thus improves the pressure application accuracy of the pressure application device 100.

[0138] As an example, the guide groove extends along a first direction, and the main body 211 abuts against the two opposing groove walls along a third direction of the guide groove to limit the position of the pressure unit 21 along the third direction.

[0139] In some embodiments, please refer to Figure 7 At least one wall of the guide groove is recessed with a limiting groove 1211 extending in a first direction, and the main body 211 is protruding with a limiting part 214, which is inserted into the limiting groove 1211. This effectively reduces the risk of the pressure unit 21 disengaging from the guide groove, thereby effectively improving the reliability of the pressure device 100.

[0140] As an example, the limiting groove 1211 is recessed in at least one groove wall of the guide groove along the third direction, and the limiting part 214 protrudes from the main body 211 along the third direction and is inserted into the limiting groove 1211 to limit the position of the main body 211 along the second direction, thereby reducing the risk of the pressure unit 21 dislodging from the guide groove.

[0141] By adopting the above technical solution, it is easy to form the guide structure 121, which effectively reduces the manufacturing cost of the pressure device 100.

[0142] Secondly, embodiments of this application provide a battery manufacturing apparatus, including the pressure application device 100 described in any of the above embodiments.

[0143] The battery manufacturing equipment provided in this application embodiment effectively saves the changeover time of the pressure device 100 by adopting the pressure device 100 described in any of the above embodiments, thereby effectively improving the production efficiency of the battery device 200.

[0144] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
