Description

Technical Field

[0001] This application belongs to the field of battery assembly technology, and specifically relates to a press-fitting device. Background Technology

[0002] With the development of battery technology, batteries are being applied in more and more fields, gradually replacing traditional fossil fuels in the automotive power sector. Batteries can store chemical energy and controllably convert it into electrical energy. In recyclable batteries, the active materials can be reactivated through charging after discharge, allowing for continued use.

[0003] In the early stages of battery production, the battery casing and cover need to be press-fitted. Most related technologies use press-fitting equipment, but existing press-fitting equipment has complex processes and high labor costs for large-scale battery production lines. Therefore, improving the press-fitting efficiency of the casing and cover is a key factor in improving battery production efficiency and reducing press-fitting costs. Summary of the Invention

[0004] This application provides a pressing device for improving pressing efficiency, pressing yield, and reducing pressing costs.

[0005] To solve the above-mentioned technical problems, this application adopts the following technical solution: A pressing device is provided for pressing battery casings and covers. The pressing device includes a positioning assembly and a pressing top assembly. The positioning assembly has a first positioning part and a second positioning part, wherein the cover is limited to the first positioning part, and the end of the casing used for connecting to the cover is limited to the second positioning part. The pressing top assembly is disposed above the positioning assembly, and the pressing top assembly and the positioning assembly can move relative to each other along the pressing direction. The first positioning part for positioning the cover and the second positioning part for positioning the casing are disposed on the same component, that is, the first positioning part and the second positioning part are disposed on the positioning assembly. When pressing casings and covers of different specifications and models are required, only the corresponding positioning assembly needs to be replaced to quickly perform the pressing process on the corresponding casings and covers. Based on this, the number of change parts required when pressing different types of casings and covers can be effectively reduced, thereby effectively reducing the pressing cost. Furthermore, the pressing assembly is positioned above the positioning assembly. When the pressing equipment presses the housing and cover, after the housing and cover are positioned on the positioning assembly, the pressing assembly can directly move along the pressing direction to the end of the housing away from the cover and abut against that end. This eliminates the need for the pressing assembly to position the end of the housing away from the cover, allowing it to evenly transmit the pressing force to the housing. This results in higher pressing stability for the pressing equipment, improves the pressing yield of the housing and cover, effectively reduces the number of processes involved in pressing the housing and cover, and thus significantly improves the pressing efficiency of the housing and cover.

[0006] In some embodiments, the positioning component includes a first floating component, and / or the pressing component includes a second floating component. The positioning component and the pressing component are configured as floating components, thereby ensuring that during the pressing process of the pressing equipment pressing the housing and the cover along the pressing direction, the end of the housing facing away from the cover is in planar contact with the pressing component, and the cover is in planar contact with the positioning component. This results in stable force distribution on the cover and housing during the pressing process, effectively improving the pressing yield of the housing and the cover.

[0007] In some embodiments, the first floating component includes a positioning seat and a positioning plate. The positioning plate is disposed on the positioning seat, and the positioning seat and the positioning plate are floatingly connected. A first positioning part and a second positioning part are disposed on the side of the positioning plate opposite to the positioning seat. The positioning plate is disposed on the positioning seat, and as a positioning housing and cover, the positioning plate is floatingly connected to the positioning seat, which enables the cover and housing to be subjected to stable force during the pressing process, thereby effectively improving the pressing yield of the housing and cover.

[0008] In some embodiments, the positioning assembly further includes a floating connection assembly. The floating connection assembly is disposed between the positioning seat and the positioning plate along the pressing direction and is movably connected to both the positioning seat and the positioning plate. The positioning seat and the positioning plate are floatingly connected through the floating connection assembly, which enables the cover and the housing to be subjected to stable force during the pressing process, thereby effectively improving the pressing yield of the housing and the cover.

[0009] In some embodiments, the positioning seat has a first limiting hole on the side near the positioning plate, and the positioning plate has a second limiting hole on the side near the positioning seat. The first and second limiting holes are arranged along the pressing direction. The floating connection assembly includes a first positioning post. One end of the first positioning post is limited within the first limiting hole, and the other end is limited within the second limiting hole. The first positioning post is movably connected to the positioning seat and the positioning plate along the pressing direction. The arrangement of the first and second limiting holes along the pressing direction ensures good alignment between the positioning seat and the positioning plate connected by the first positioning post, preventing translation of the positioning plate and the positioning seat along a plane perpendicular to the pressing direction. This effectively improves the stability of the cover and the housing under pressure during pressing, thereby effectively improving the pressing yield of the housing and the cover.

[0010] In some embodiments, the positioning seat has a third limiting hole on the side near the positioning plate, the third limiting hole being located in the middle region of the positioning seat. The floating connection assembly further includes a second positioning post. One end of the second positioning post is fixedly connected to the side of the positioning plate near the positioning seat, and the other end is confined within the third limiting hole and movably connected to the positioning seat. The positioning plate has a third limiting hole located in the middle region of the positioning seat. The second positioning post is fixedly connected to the positioning plate and confined within the third limiting hole. This allows the positioning seat and the positioning plate to maintain good alignment while ensuring the stability of the force applied to the cover and housing during press-fitting, thereby effectively improving the press-fitting yield of the cover and housing.

[0011] In some embodiments, the floating connection assembly further includes an elastic element. The elastic element is disposed between the positioning seat and the positioning plate, and its two ends abut against the positioning seat and the positioning plate respectively. Because of the elastic element between the positioning seat and the positioning plate, the positioning plate and the positioning seat can reset after the pressing equipment releases the pressing force, thereby not affecting the positioning of the positioning assembly for the next housing and cover, and thus improving the pressing efficiency of the pressing equipment.

[0012] In some embodiments, the pressing equipment further includes a pressing mechanism. The pressing mechanism is connected to the pressing top assembly and provides a pressing force to the pressing top assembly along the pressing direction. The connection between the pressing mechanism and the pressing top assembly, and the provision of a pressing force to the pressing top assembly by the pressing mechanism, effectively improves the pressing efficiency of the pressing equipment.

[0013] In some embodiments, the pressing equipment further includes: a column and a base assembly; the base assembly is fixedly connected to the column, wherein the pressing mechanism and the positioning assembly are respectively spaced apart on the column along the pressing direction. The spaced-apart arrangement of the pressing mechanism and the positioning assembly on the same column ensures that when the pressing mechanism drives the pressing top assembly to move relative to the positioning assembly, the movement direction of the pressing top assembly is consistent with the pressing direction, thereby effectively improving the pressing yield of the housing and cover.

[0014] In some embodiments, the pressing equipment further includes an adjustment component. The adjustment component is connected to the column, and a positioning component is disposed on the adjustment component. The adjustment component is configured to adjust the distance between the positioning component and the pressing top component along the pressing direction. Based on this, the distance between the positioning component and the pressing component can be adjusted by the adjustment component, thereby improving the adaptability of the pressing equipment to different types of housings and covers, increasing the applicability of the pressing equipment, and effectively reducing the pressing cost of housings and covers.

[0015] In some embodiments, the base assembly includes a base body, an adsorption element, and multiple support rods. One end of each support rod is rotatably connected to the base body, and the axis of rotation of the support rod relative to the base body is perpendicular to the support plane of the base body. The adsorption element is disposed at the other end of the support rod and is used to adsorb and adhere to the support plane. The multiple support rods rotate relative to the base body within the support plane, which effectively increases the support area between the base body and the support plane, thereby improving the support stability of the pressing equipment and thus effectively enhancing the safety of the pressing equipment. Furthermore, one end of each support rod is also provided with an adsorption element, which is used to adsorb and adhere to the support plane, thereby further enhancing the safety of the pressing equipment.

[0016] In some embodiments, the pressing mechanism includes a sliding seat, a fixed seat, and a pressure rod assembly. The sliding seat is fixedly connected to the pressure top assembly; the fixed seat is slidably connected to the sliding seat, and the sliding seat can slide relative to the fixed seat along the pressing direction; the pressure rod assembly is hinged to both the sliding seat and the fixed seat, and is used to transmit the pressing force to the sliding seat. The pressing mechanism, through the slidable connection between the sliding seat and the fixed seat, drives the pressure top assembly to move relative to the positioning assembly along the pressing direction. Furthermore, the pressing mechanism is equipped with a pressure rod assembly, which transmits the pressing force to the sliding seat, effectively saving the user's effort and thus effectively improving the pressing efficiency of the pressing equipment.

[0017] In some embodiments, the sliding seat can slide relative to the fixed seat for a preset stroke along the pressing direction. The preset stroke includes an upper stroke segment and a lower stroke segment. The pressing mechanism further includes a first elastic element and a second elastic element. One end of the first elastic element is hinged to the sliding seat, and the other end is hinged to the fixed seat; one end of the second elastic element is hinged to the sliding seat, and the other end is hinged to the fixed seat; wherein, in the upper stroke segment, the elastic force of the first elastic element is opposite to the pressing direction, and the elastic force of the second elastic element is opposite to the pressing direction; in the lower stroke segment, the elastic force of the first elastic element is in the same direction as the pressing direction, and the elastic force of the second elastic element is opposite to the pressing direction. Based on this, when the press-fitting equipment presses the housing and cover, the first elastic element provides elastic force to the sliding seat in the lower stroke section, effectively saving the user's physical strength. Furthermore, the first elastic element in the upper stroke section and the second elastic element in both the upper and lower stroke sections provide elastic force to the sliding seat away from the press-fitting direction. On the one hand, after press-fitting, the first and second elastic elements provide elastic force to the sliding seat away from the press-fitting direction, thereby reducing the physical exertion on the user during the sliding seat's reset process, thus effectively improving the press-fitting efficiency of the equipment. On the other hand, when the press-fitting equipment presses the housing and cover along the press-fitting direction, the second elastic element provides elastic force to the sliding seat away from the press-fitting direction, thus buffering the sliding seat to a certain extent and preventing the press-fitting components from damaging the housing and cover, thereby effectively improving the press-fitting yield of the equipment.

[0018] In some embodiments, the pressing mechanism further includes an anti-collision member. The anti-collision member is disposed at the starting point of the upper stroke section along the pressing direction and / or at the ending point of the lower stroke section along the pressing direction. The anti-collision member, disposed at the starting point of the upper stroke section, effectively prevents violent collision between the sliding seat and the fixed seat during the initial force accumulation phase of the pressing operation by the user, thereby effectively extending the service life of the pressing equipment. The anti-collision member, disposed at the ending point of the lower stroke section, effectively prevents violent collision between the pressing components and the housing, thereby effectively improving the pressing yield of the pressing equipment.

[0019] In some embodiments, the sidewall of the second positioning part and the outer sidewall of the housing are spaced apart by a preset gap distance along a horizontal direction perpendicular to the pressing direction. In other words, the outer circumferential dimension of the housing at one end of the second positioning part is smaller than that of the second positioning part, which facilitates the housing to be quickly positioned within the second positioning part, thereby effectively improving the pressing efficiency of the pressing equipment.

[0051] Currently, considering market development prospects and application trends, batteries have been widely used in various fields due to their advantages such as high energy density, high power density, high cycle life, and long storage time. These include applications in various energy storage power systems such as hydropower, thermal power, wind power, and solar power plants, as well as providing power for high-power devices such as electric bicycles, electric motorcycles, and electric vehicles, and in multiple fields such as military equipment and aerospace.

[0052] For example, regarding vehicles, please refer to [link / reference]. Figure 1 , Figure 1 This is a structural schematic diagram of one embodiment of the vehicle described in this application. The vehicle can be a gasoline-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle. New energy vehicles can be pure electric vehicles, hybrid electric vehicles, or range-extended electric vehicles, etc. A battery 1 is installed inside the vehicle. The battery 1 can be fixedly mounted on the vehicle body, for example, at the bottom, front, or rear of the vehicle body. The battery 1 can be used to supply power to the vehicle; for example, the battery 1 can serve as the vehicle's operating power source. The vehicle may also include a controller 2 and a motor 3. The controller 2 is used to control the battery 1 to supply power to the motor 3, for example, for the vehicle's starting, navigation, and operating power needs. The battery 1 can not only serve as the vehicle's operating power source but also as the vehicle's driving power source, replacing or partially replacing gasoline or natural gas to provide driving power to the vehicle.

[0053] In some embodiments, battery 1 can serve not only as the operating power source for the vehicle, but also as the driving power source for the vehicle, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle.

[0054] This application proposes a battery, such as Figure 2 As shown, Figure 2This is a schematic diagram of the structure of a battery according to an embodiment of this application. The battery 1 includes a housing 10 and a battery cell 20, with the battery cell 20 housed within the housing 10. The housing 10 provides a space for the battery cell 20, and can have various structures. In some embodiments, the housing 10 may include a first portion 11 and a second portion 12, which overlap each other, jointly defining a space for accommodating the battery cell 20. The second portion 12 may be a hollow structure with one open end, and the first portion 11 may be a plate-like structure, covering the open side of the second portion 12 so that the first portion 11 and the second portion 12 jointly define the space. Alternatively, both the first portion 11 and the second portion 12 may be hollow structures with one open side, with the open side of the first portion 11 covering the open side of the second portion 12. Of course, the housing 10 formed by the first portion 11 and the second portion 12 can have various shapes, such as a cylinder, a cuboid, etc.

[0055] In battery 1, there can be multiple battery cells 20, which can be connected in series, parallel, or a combination thereof. A combination thereof means that multiple battery cells 20 are connected in both series and parallel. Multiple battery cells 20 can be directly connected in series, parallel, or a combination thereof, and then the entire assembly of the multiple battery cells 20 is housed within the housing 10. Alternatively, the battery can be composed of multiple battery cells 20 first connected in series, parallel, or a combination thereof to form a battery module, and then these battery modules are connected in series, parallel, or a combination thereof to form a whole, which is also housed within the housing 10. Battery 1 may also include other structures; for example, it may include a busbar component for electrical connection between the multiple battery cells 20.

[0056] Each battery cell 20 can be a secondary battery or a primary battery; it can also be a lithium-ion battery, a lithium-sulfur battery, a sodium-ion battery, or a magnesium-ion battery, but is not limited to these. The battery cell 20 can be cylindrical, flat, cuboid, or other shapes.

[0057] Specifically, such as Figure 3 As shown, Figure 3 This is a schematic diagram of the structure of an embodiment of the electrode assembly of this application. A battery cell 20 refers to the smallest unit constituting a battery, and the battery cell 20 includes an end cap 21, a housing 22, an electrode assembly 23, and other functional components. The end cap 21 is a component that covers the opening of the housing 22 to isolate the internal environment of the battery cell 20 from the external environment. Not limited to this, the shape of the end cap 21 can be adapted to the shape of the housing 22 to fit the housing 22.

[0058] In some embodiments, the end cap 21 may be provided with functional components such as electrode terminals 21a. The electrode terminals 21a can be used to electrically connect with the electrode assembly 23 for outputting or inputting electrical energy of the battery cell 20.

[0059] In some embodiments, the end cap 21 may also be provided with a pressure relief mechanism for releasing the internal pressure when the internal pressure or temperature of the battery cell 20 reaches a threshold.

[0060] In some embodiments, an insulating element may be provided on the inner side of the end cap 21. The insulating element can be used to isolate the electrical connection components in the housing 22 from the end cap 21 to reduce the risk of short circuit.

[0061] The housing 22 is a component used to cooperate with the end cap 21 to form the internal environment of the battery cell 20. This internal environment can accommodate the electrode assembly 23, electrolyte, and other components. The housing 22 and the end cap 21 can be independent components. An opening can be provided on the housing 22, and the end cap 21 closes the opening to form the internal environment of the battery cell 20. Alternatively, the end cap 21 and the housing 22 can be integrated. Specifically, the end cap 21 and the housing 22 can form a common connecting surface before other components are inserted into the housing. When it is necessary to encapsulate the interior of the housing 22, the end cap 21 closes the housing 22. The housing 22 can have various shapes and sizes, such as cuboid, cylindrical, or hexagonal prism. Specifically, the shape of the housing 22 can be determined according to the specific shape and size of the electrode assembly 23.

[0062] Electrode assembly 23 is a component in the battery cell 20 where electrochemical reactions occur. The housing 22 may contain one or more electrode assemblies 23. The electrode assembly 23 is also provided with tabs 23a. During the charging and discharging process of the battery, the positive electrode active material and the negative electrode active material react with the electrolyte, and the tabs 23a are connected to the electrode terminals 21a to form a current loop.

[0063] Related technologies use press-fitting equipment to press-fit the casing and cover to form a box. However, the press-fitting process of existing press-fitting equipment is complex and has high labor costs for large-scale battery production lines. Therefore, improving the press-fitting efficiency of the casing and cover is a key factor in improving battery production efficiency and reducing press-fitting costs.

[0064] Therefore, this application provides a pressing device 30, which can be used for pressing the housing 22 and cover of a battery cell 20 in a vehicle, wherein the cover includes the end cap 21 of the battery cell 20. The pressing device 30 can also be used for pressing the first part 11 or the second part 12 in a housing 10, for example, pressing the frame 11b of the first part 11 and the pressure cap 11a of the first part 11 to form the first part 11. Similarly, pressing the frame 12b of the second part 12 and the pressure cap 12a of the second part 12 to form the second part 12.

[0065] This application primarily focuses on the specific application of the pressing equipment 30 in pressing the end caps 21 and housings 22 of batteries. The pressing equipment 30 can uniformly transmit the pressing force to the housing 22, thereby achieving high pressing stability, improving the pressing yield of the housing 22 and caps, and effectively reducing the pressing steps for the housing 22 and caps, thus significantly improving the pressing efficiency. This application mainly focuses on the application of the pressing equipment 30 in the pressing process of the end caps and housings of battery cells 20.

[0066] This application provides a pressing device 30, such as... Figure 4 and Figure 5 The above, Figure 4 This is a three-dimensional structural schematic diagram of an embodiment of the pressing equipment of this application; Figure 5 yes Figure 4 A schematic diagram of the pressing equipment from direction A. The pressing equipment 30 is used to press the housing 22 and the cover of the battery cell 20, wherein the housing 22 includes the housing 22 of the battery cell 20 of any of the above-mentioned structural types, and the cover includes the end cap 21 of the battery cell 20 of any of the above-mentioned structural types.

[0067] The pressing equipment 30 includes a positioning assembly 100 and a pressing assembly 200. The positioning assembly 100 is provided with a first positioning part 111 and a second positioning part 112, wherein the cover is limited to the first positioning part 111, and the end of the housing 22 used to connect with the cover is limited to the second positioning part 112; the pressing assembly 200 is disposed above the positioning assembly 100, and the pressing assembly 200 and the positioning assembly 100 can move relative to each other along the pressing direction X1.

[0068] Specifically, the pressing assembly 200 provides pressing force along the pressing direction X1 to press the housing 22 and the cover. The positioning assembly 100 is used to simultaneously position the cover and the housing 22. In this embodiment, during the pressing process in the pressing equipment 30, the pressing assembly 200 can move relative to the positioning assembly 100 along the pressing direction X1 and reset along the reset direction X2, which is opposite to the pressing direction X1. In other embodiments, during the pressing process in the pressing equipment 30, the positioning assembly 100 and the pressing assembly 200 can move simultaneously, or either the positioning assembly 100 or the pressing assembly 200 can move; these details are not elaborated here.

[0069] The first positioning part 111 for positioning plate 110 and the second positioning part 112 for positioning housing 22 are disposed on the same component, that is, the first positioning part 111 and the second positioning part 112 are disposed on the positioning assembly 100. When it is necessary to press-fit housing 22 and cover of different specifications, only the corresponding positioning assembly 100 needs to be replaced to quickly perform the pressing process on the corresponding housing 22 and cover. Based on this, the number of change parts of the pressing equipment 30 when pressing different types of housing 22 and cover can be effectively reduced, thereby effectively reducing the pressing cost. Furthermore, the pressing top assembly 200 is disposed above the positioning assembly 100 along the pressing direction X1. When the pressing equipment 30 presses the housing 22 and cover, after the housing 22 and cover are positioned on the positioning assembly 100, the pressing top assembly 200 can directly move along the pressing direction X1 to the end of the housing 22 away from the cover and abut against the end of the housing 22 away from the cover. Based on this, the pressing assembly 200 does not need to position the end of the housing 22 away from the cover, and can uniformly transmit the pressing force to the housing 22. This makes the pressing equipment 30 have high pressing stability, improves the pressing yield of the housing 22 and the cover, and can also effectively reduce the pressing process of the housing 22 and the cover, thereby effectively improving the pressing efficiency of the housing 22 and the cover.

[0070] Unlike existing technologies, the pressing equipment 30 of this application includes a positioning component 100 and a pressing top component 200. The positioning component 100 is provided with a first positioning part 111 and a second positioning part 112, wherein the cover is limited to the first positioning part 111, and the end of the housing 22 used for connecting with the cover is limited to the second positioning part 112; the pressing top component 200 is disposed above the positioning component 100, and the pressing top component 200 and the positioning component 100 can move relative to each other along the pressing direction X1. In this way, the pressing top component 200 does not need to position the end of the housing 22 away from the cover, and can uniformly transmit the pressing force to the housing 22, thereby giving the pressing equipment 30 higher pressing stability, improving the pressing yield of the housing 22 and the cover, and effectively reducing the pressing steps of the housing 22 and the cover, thereby effectively improving the pressing efficiency of the housing 22 and the cover. Furthermore, the first positioning part 111 for the positioning plate 110 body and the second positioning part 112 for the positioning housing 22 are provided on the same component, that is, the first positioning part 111 and the second positioning part 112 are provided on the positioning assembly 100. When it is necessary to press-fit housings 22 and covers of different specifications and models, it is only necessary to replace the corresponding positioning assembly 100 to quickly perform the pressing process on the corresponding housings 22 and covers. Based on this, the number of change parts of the pressing equipment 30 when pressing different types of housings 22 and covers can be effectively reduced, thereby effectively reducing the pressing cost.

[0071] In some embodiments, such as Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, Figure 6 yes Figure 1 A three-dimensional structural diagram of an embodiment of the positioning component; Figure 7 yes Figure 6 A schematic diagram of the B-direction positioning component; Figure 8 yes Figure 1 A three-dimensional structural schematic diagram of an embodiment of a medium-pressure top assembly; Figure 9 yes Figure 8 A schematic diagram of the pressure-top assembly along direction C. The positioning assembly 100 includes a first floating assembly, and / or the pressure-top assembly 200 includes a second floating assembly. In this embodiment, the positioning assembly 100 and the pressure-top assembly 200 are configured as floating assemblies, i.e., the first floating assembly and the second floating assembly. Based on this, during the pressing process of the pressing equipment 30 pressing the housing 22 and the cover along the pressing direction X1, the end of the housing 22 away from the cover is in planar contact with the pressure-top assembly 200, and the cover is in planar contact with the positioning assembly 100. This ensures that the cover and the housing 22 are subjected to stable force during the pressing process, thereby effectively improving the pressing yield of the housing 22 and the cover. In other embodiments, only either the positioning assembly 100 or the pressure-top assembly 200 may be configured as a floating assembly, which will not be described in detail here.

[0072] In some embodiments, such as Figure 6 and Figure 7 As shown. The first floating component includes: a positioning seat 120 and a positioning plate 110. The positioning plate 110 is disposed on the positioning seat 120, and the positioning seat 120 and the positioning plate 110 are floatingly connected. The first positioning part 111 and the second positioning part 112 are disposed on the side of the positioning plate 110 away from the positioning seat 120.

[0073] Specifically, the specific structural shape of the first positioning part 111 can be designed according to the specific structure of the cover, and the specific structural shape of the second positioning part 112 can be designed according to the specific structure of the end where the shell 22 is connected to the cover. These details will not be elaborated here. The positioning plate 110 is set on the positioning seat 120, and as the positioning plate 110 for positioning the shell 22 and the cover, it is floatingly connected to the positioning seat 120. This enables the cover and shell 22 to be subjected to stable force during the pressing process, thereby effectively improving the pressing yield of the shell 22 and the cover.

[0074] In some embodiments, see Figure 6 and Figure 7 The first floating component also includes a floating connection component 130. The floating connection component 130 is disposed between the positioning seat 120 and the positioning plate 110 along the pressing direction X1, and is movably connected to both the positioning seat 120 and the positioning plate 110. The positioning seat 120 and the positioning plate 110 are floatingly connected through the floating connection component 130. This ensures the stability of the force applied to the cover and housing 22 during the pressing process, thereby effectively improving the pressing yield of the housing 22 and the cover.

[0075] In some embodiments, see Figure 6 and Figure 7 The positioning seat 120 has a first limiting hole (not shown in the figure) on the side near the positioning plate 110, and the positioning plate 110 has a second limiting hole (not shown in the figure) on the side near the positioning seat 120. The first limiting hole and the second limiting hole are arranged along the pressing direction X1. The floating connection assembly 130 includes a first positioning post 131. One end of the first positioning post 131 is limited to the first limiting hole, and the other end is limited to the second limiting hole. The first positioning post 131 is movably connected to the positioning seat 120 and the positioning plate 110 along the pressing direction X1. The arrangement of the first limiting hole and the second limiting hole along the pressing direction X1 ensures that the positioning seat 120 and the positioning plate 110 connected by the first positioning post 131 maintain good alignment, preventing the positioning plate 110 and the positioning seat 120 from translating along a plane perpendicular to the pressing direction X1. This effectively improves the stability of the force on the cover and the housing 22 during the pressing process, thereby effectively improving the pressing yield of the housing 22 and the cover.

[0076] For example, in this embodiment, the floating connection assembly 130 includes four first positioning posts 131. The edge region of the positioning seat 120 near the positioning plate 110 is provided with four evenly arranged first limiting holes. The edge region of the positioning plate 110 near the positioning seat 120 is provided with four second limiting holes corresponding to the first limiting holes. The four first positioning posts 131 are respectively installed in the corresponding first limiting holes and second limiting holes. Based on this, the positioning seat 120 and the positioning plate 110 are positioned and restricted by the four first positioning posts 131, which can make the positioning seat 120 and the positioning plate 110 maintain better alignment, thereby more effectively improving the stability of the force on the cover and the housing 22 during the pressing process, and thus effectively improving the pressing yield of the housing 22 and the cover.

[0077] In some embodiments, see further. Figure 6 and Figure 7 The positioning base 120 has a third limiting hole on the side near the positioning plate 110. The third limiting hole is located in the middle area of ​​the positioning plate 110. The floating connection assembly 130 also includes a second positioning post 133. One end of the second positioning post 133 is fixedly connected to the side of the positioning plate 110 near the positioning base 120, and the other end is limited in the third limiting hole and movably connected to the positioning base 120.

[0078] Specifically, in this embodiment, one end of the second positioning post 133 is provided with a cone head, wherein the cone head is confined within the third limiting hole. In other embodiments, the second positioning post 133 may also be provided with other structural shapes. The positioning seat 120 is provided with a third limiting hole, and the third limiting hole is located in the middle area of ​​the positioning seat 120. The second positioning post 133 is fixedly connected to the positioning plate 110 and confined within the third limiting hole. Based on this, the positioning seat 120 and the positioning plate 110 can maintain good alignment, while also ensuring the stability of the force on the cover and the housing 22 during the pressing process, thereby effectively improving the pressing yield of the housing 22 and the cover.

[0079] In some embodiments, the floating connection assembly 130 further includes an elastic element 132. The elastic element 132 is disposed between the positioning seat 120 and the positioning plate 110, and its two ends abut against the positioning seat 120 and the positioning plate 110 respectively. With the elastic element 132 disposed between the positioning seat 120 and the positioning plate 110, the positioning plate 110 and the positioning seat 120 can reset after the pressing force of the pressing equipment 30 is released, thus not affecting the positioning of the positioning assembly 100 on the next housing 22 and the cover, thereby improving the pressing efficiency of the pressing equipment 30. For example, in this embodiment, four elastic elements 132, such as springs, are evenly arranged between the positioning plate 110 and the positioning seat 120. This allows the positioning seat 120 and the positioning plate 110 to maintain their floating connection characteristics while also enabling the positioning seat 120 and the positioning plate 110 to automatically reset, thereby effectively improving the pressing efficiency of the pressing equipment 30.

[0080] In some embodiments, such as Figure 8 and Figure 9 As shown, the second floating component includes a pressure seat 210 and a pressure plate 220. The pressure plate 220 is disposed on the pressure seat 210, and the pressure seat 210 and the pressure plate 220 are floatingly connected. The pressure plate 220 is disposed on the pressure seat 210, and as the positioning housing 22 and the cover, the pressure plate 220 is floatingly connected to the pressure seat 210, which enables the cover and housing 22 to be subjected to stable force during the pressing process, thereby effectively improving the pressing yield of the housing 22 and the cover.

[0081] In some embodiments, such as Figure 8 and Figure 9 As shown, the second floating assembly further includes a floating connection assembly 230. The floating connection assembly 230 is disposed between the pressure seat 210 and the pressure plate 220 along the pressing direction X1, and is movably connected to both the pressure seat 210 and the pressure plate 220. The pressure seat 210 and the pressure plate 220 are floatingly connected through the floating connection assembly 230. This ensures the stability of the force applied to the cover and housing 22 during the pressing process, thereby effectively improving the pressing yield of the housing 22 and the cover.

[0082] In some embodiments, such as Figure 8 and Figure 9As shown, the top pressure seat 210 has a fourth limiting hole (not shown) on the side near the top pressure plate 220, and the top pressure plate 220 has a fifth limiting hole (not shown) on the side near the top pressure seat 210. The fourth and fifth limiting holes are arranged along the pressing direction X1. The floating connection assembly 230 includes a third positioning post 231. One end of the third positioning post 231 is limited to the fourth limiting hole, and the other end is limited to the fifth limiting hole. The fourth positioning post 231 is movably connected to the top pressure seat 210 and the top pressure plate 220 along the pressing direction X1. The fourth and fifth limiting holes are arranged along the pressing direction X1, which enables the pressing seat 210 and the pressing plate 220 connected by the third positioning post 231 to maintain good alignment, so as to prevent the pressing plate 220 and the pressing seat 210 from translating along the plane perpendicular to the pressing direction X1. This effectively improves the stability of the force on the cover and the shell 22 during the pressing process, and thus effectively improves the pressing yield of the shell 22 and the cover.

[0083] For example, in this embodiment, the floating connection assembly 230 includes four third positioning posts 231. The edge region of the pressure seat 210 near the pressure plate 220 is provided with four evenly arranged fourth limiting holes. The edge region of the pressure plate 220 near the pressure seat 210 is provided with four fifth limiting holes corresponding to the fourth limiting holes. The four third positioning posts 231 are respectively installed in the corresponding fourth and fifth limiting holes. Based on this, the pressure seat 210 and the pressure plate 220 are positioned and restricted by the four third positioning posts 231, which can make the pressure seat 210 and the pressure plate 220 maintain better alignment, thereby more effectively improving the stability of the force on the cover and the shell 22 during the pressing process, and thus effectively improving the pressing yield of the shell 22 and the cover.

[0084] In some embodiments, see further. Figure 8 and Figure 9 The pressure seat 210 has a sixth limiting hole on the side near the pressure plate 220. The sixth limiting hole is located in the middle area of ​​the pressure seat 210. The floating connection assembly 230 also includes a fourth positioning post 233. One end of the fourth positioning post 233 is fixedly connected to the side of the pressure plate 220 near the pressure seat 210, and the other end is limited in the sixth limiting hole and movably connected to the pressure seat 210. The pressure seat 210 is provided with a sixth limiting hole, and the sixth limiting hole is located in the middle area of ​​the pressure seat 210. The fourth positioning post 233 is fixedly connected to the pressure plate 220 and limited in the sixth limiting hole. Based on this, the pressure seat 210 and the pressure plate 220 can maintain good alignment, and the cover and housing 22 can be subjected to stable force during the pressing process, thereby effectively improving the pressing yield of the housing 22 and the cover.

[0085] In some embodiments, the floating connection assembly 230 further includes an elastic element 232. The elastic element 232 is disposed between the pressure seat 210 and the pressure plate 220, and its two ends abut against the pressure seat 210 and the pressure plate 220 respectively. The elastic element 232 is disposed between the pressure seat 210 and the pressure plate 220, so that after the pressing force of the pressing device 30 is released, the pressure plate 220 and the pressure seat 210 can be reset, thereby not affecting the positioning of the positioning assembly 100 for the next housing 22 and the cover, and thus improving the pressing efficiency of the pressing device 30. For example, in this embodiment, four elastic elements 232, such as springs, are evenly arranged between the pressure plate 220 and the pressure seat 210. This allows the pressure seat 210 and the pressure plate 220 to maintain their floating connection characteristics while also enabling the pressure seat 210 and the pressure plate 220 to automatically reset, thereby effectively improving the pressing efficiency of the pressing device 30.

[0086] In some embodiments, see Figure 4 , Figure 5 and Figure 10 , Figure 10 yes Figure 4 A partial structural schematic diagram of one embodiment of the pressing mechanism is shown. The pressing equipment 30 further includes a pressing mechanism 300. The pressing mechanism 300 is connected to the pressing top assembly 200 and provides a pressing force to the pressing top assembly 200 along the pressing direction X1. The connection between the pressing mechanism 300 and the pressing top assembly 200, and the provision of pressing force to the pressing top assembly 200 by the pressing mechanism 300, effectively improves the pressing efficiency of the pressing equipment 30.

[0087] In some embodiments, see Figure 4 and Figure 5 The pressing equipment 30 also includes: a column 400 and a base assembly 500; the base assembly 500 is fixedly connected to the column 400, wherein the pressing mechanism 300 and the positioning assembly 100 are respectively spaced apart on the column 400 along the pressing direction X1. The spaced-apart arrangement of the pressing mechanism 300 and the positioning assembly 100 on the same column 400 ensures that when the pressing mechanism 300 drives the pressing top assembly 200 to move relative to the positioning assembly 100, the movement direction of the pressing top assembly 200 is consistent with the pressing direction X1, thereby effectively improving the pressing yield of the housing 22 and the cover. In this embodiment, the column 400 is configured as a columnar structure; in other embodiments, the column 400 may also be configured with other structural shapes.

[0088] In some embodiments, see Figure 4 and Figure 5The pressing equipment 30 also includes an adjustment component 700. The adjustment component 700 is connected to the column 400, and the positioning component 100 is mounted on the adjustment component 700. The adjustment component 700 is configured to adjust the distance between the positioning component 100 and the pressing top component 200 along the pressing direction X1. Based on this, the distance between the positioning component 100 and the pressing top component 200 can be adjusted via the adjustment component 700, thereby improving the adaptability of the pressing equipment 30 to different types of housings 22 and covers, increasing the applicability of the pressing equipment 30, and effectively reducing the pressing cost of the housings 22 and covers.

[0089] In some embodiments, see Figure 4 and Figure 5 The adjustment assembly 700 includes a lead screw 710, a nut 720, a handwheel 730, a shaft end baffle 740, and a bearing member 750. The nut 720 is sleeved on the outer periphery of the lead screw 710 to form a lead screw 710 nut 720 mechanism. The handwheel 730 is fixed to one end of the lead screw 710. The shaft end baffle 740 is disposed at the end of the lead screw 710 where the handwheel 730 is disposed to restrict the movement of the handwheel 730 relative to the lead screw 710 along the axial direction of the lead screw 710. The positioning component 100 is mounted on the support member 750. One end of the support member 750 is fixedly connected to the nut 720. The support member 750 has a through hole. The column 400 passes through the through hole of the support member 750 and is movably connected to the support member 750. The lead screw 710 is arranged parallel to and spaced apart from the column 400. Based on this, by rotating the handwheel 730, the nut 720 can be driven to move the support member 750 relative to the column 400 along the axial direction of the lead screw 710 or the column 400, thereby adjusting the distance between the positioning component 100 and the pressing component 200. This improves the adaptability of the pressing equipment 30 to different types of housings 22 and covers, increases the practicality of the pressing equipment 30, and effectively reduces the pressing cost of the housings 22 and covers.

[0090] In some embodiments, see Figure 5 The positioning component 700 also includes a locking element 760. The bearing component is provided with a locking hole, and the locking element 760 can pass through the locking hole and abut against the column 400, thereby restricting the relative movement between the bearing component 750 and the column 400. Based on this, after the user adjusts the relative positional relationship between the positioning component 100 and the pressing component 200 through the screw 710 and nut 720 mechanism, the user can further restrict the relative movement between the positioning component 100 and the column 400 by passing the locking element 760 through the locking hole and abutting against the column 400, thereby preventing the positioning component 100 from sliding down during the pressing process, and thus effectively improving the stability and pressing yield of the pressing equipment 30.

[0091] In some embodiments, see Figure 4 , Figure 5 and Figure 10The pressing mechanism 300 includes a sliding seat 310, a fixed seat 320, and a pressure rod assembly 330. The sliding seat 310 is fixedly connected to the pressing top assembly 200; the fixed seat 320 is slidably connected to the sliding seat 310, and the sliding seat 310 can slide relative to the fixed seat 320 along the pressing direction X1; the pressure rod assembly 330 is hinged to both the sliding seat 310 and the fixed seat 320, and is used to transmit the pressing force to the sliding seat 310. The pressing mechanism 300 is slidably connected to the fixed seat 320 through the sliding seat 310, thereby driving the pressing top assembly 200 to move relative to the positioning assembly 100 along the pressing direction X1. The pressing mechanism 300 is also provided with the pressure rod assembly 330, which transmits the pressing force to the sliding seat 310, effectively saving the user's physical strength and thus effectively improving the pressing efficiency of the pressing equipment 30.

[0092] In some embodiments, see Figure 4 , Figure 5 and Figure 10 The sliding seat 310 can slide relative to the fixed seat 320 along the pressing direction X1 for a preset stroke. The preset stroke includes an upper stroke segment and a lower stroke segment. The pressing mechanism 300 also includes a first elastic element 340 and a second elastic element 350. One end of the first elastic element 340 is hinged to the sliding seat 310, and the other end is hinged to the fixed seat 320; one end of the second elastic element 350 is hinged to the sliding seat 310, and the other end is hinged to the fixed seat 320. In the upper stroke segment, the elastic force of the first elastic element 340 is opposite to the pressing direction X1, and the elastic force of the second elastic element 350 is opposite to the pressing direction X1. In the lower stroke segment, the elastic force of the first elastic element 340 is in the same direction as the pressing direction X1, and the elastic force of the second elastic element 350 is opposite to the pressing direction X1. Based on this, when the pressing equipment 30 presses the housing 22 and the cover, the first elastic element 340 provides elastic force to the sliding seat 310 in the lower stroke section, which can effectively save the user's physical strength. In addition, the first elastic element 340 in the upper stroke section and the second elastic element 350 in the upper stroke section and the lower stroke section provide elastic force to the sliding seat 310 away from the pressing direction X1 (i.e., in the same direction as the reset direction X2). On the one hand, after the pressing is completed, the first elastic element 340 and the second elastic element 350 can provide elastic force to the sliding seat 310 away from the pressing direction X1, thereby reducing the physical strength consumption of the user during the reset process of the sliding seat 310, and thus effectively improving the pressing efficiency of the pressing equipment 30. On the other hand, when the pressing equipment 30 presses the housing 22 and the cover along the pressing direction X1, the second elastic element 350 can provide the sliding seat 310 with an elastic force away from the pressing direction X1, thereby buffering the sliding seat 310 to a certain extent and preventing the pressing top assembly 200 from crushing the housing 22 and the cover, thereby effectively improving the pressing yield of the pressing equipment 30.

[0093] For example, in this embodiment, see Figure 4 , Figure 5 and Figure 10 The pressing mechanism 300 includes two first elastic elements 340 and two second elastic elements 350. Each of the first elastic elements 340 and the second elastic elements is hinged to the fixed base 320 and the mounting base according to the above connection method. The two first elastic elements 340 are distributed on both sides of the fixed base 320, and the two second elastic elements 350 are distributed on both sides of the fixed base 320. Based on this, the force on the sliding base 310 is more stable, and the sliding base 310 is prevented from shaking in the direction perpendicular to the pressing direction X1 when it moves along the pressing direction X1 and the reset direction X2. This effectively improves the stability of the pressing equipment 30 and improves the pressing yield.

[0094] In this embodiment, both the first elastic element 340 and the second elastic element 350 are nitrogen springs. In other embodiments, other elastic elements may be used as alternatives, which will not be described in detail here.

[0095] In some embodiments, see Figure 4 , Figure 5 and Figure 10 The sliding seat 310 includes a sliding block 312 and a connecting block 311 detachably connected to the sliding block 312. The sliding block 312 has a sliding groove, and the fixed seat 320 has a sliding rail. The sliding block 312 and the fixed seat 320 are slidably connected via the sliding groove and the sliding rail. A fixing part is provided on the side of the sliding block 312 facing away from the fixed seat 320, and the connecting block 311 is detachably connected to the fixing part. A first elastic member 340, a second elastic member 350, and a pressure rod assembly 330 are respectively connected to the connecting block 311. The pressure top assembly 200 is fixed to the connecting block 311. Based on this, the sliding block 312 is made a replaceable part, thereby effectively reducing the maintenance cost of the pressing equipment 30.

[0096] In some embodiments, see Figure 4 and Figure 5 The pressing mechanism 300 also includes an anti-collision member 360. The anti-collision member 360 is disposed at the starting point of the upper stroke section along the pressing direction X1, and / or at the ending point of the lower stroke section along the pressing direction X1. The anti-collision member 360, disposed at the starting point of the upper stroke section, effectively prevents the sliding seat 310 from violently colliding with the fixed seat 320 during the initial force accumulation phase of the pressing operation using the pressing mechanism 300, thereby effectively extending the service life of the pressing equipment 30. The anti-collision member 360, disposed at the ending point of the lower stroke section, effectively prevents the pressing top assembly 200 from violently colliding with the housing 22, thereby effectively improving the pressing yield of the pressing equipment 30.

[0097] In some embodiments, see Figure 4 and Figure 5The pressing equipment 30 also includes a support base 600. The support base 600 is provided with threaded rod through holes (not shown in the figure) and column through holes (not shown in the figure) spaced apart. One end of the threaded rod 710, equipped with a handwheel 730, passes through the threaded rod through hole and is rotatably connected to the support base 600. The column 400 passes through the column through hole and is connected to the support base 600. A fixing seat 320 is fixed to the support base 600. The support base 600 is also provided with a first anti-collision mounting part 610. A second anti-collision mounting part 321 is provided at the end of the fixing seat 320 facing away from the support base 600. Two anti-collision components 360 are respectively installed in the first anti-collision mounting part 610 and the second anti-collision mounting part 321.

[0098] In some embodiments, the sidewall of the second positioning part 112 and the outer sidewall of the housing 22 are spaced apart by a preset gap distance along a horizontal direction perpendicular to the pressing direction X1. In other words, the outer peripheral dimension of the housing 22 disposed at one end of the second positioning part 112 is smaller than that of the second positioning part 112, which facilitates the housing 22 to be quickly positioned in the second positioning part 112, thereby effectively improving the pressing efficiency of the pressing equipment 30.

[0099] In some embodiments, the preset gap distance is not less than 0.1 mm and not more than 0.2 mm. Based on this, the housing 22 can be quickly positioned in the second positioning part 112, while also effectively preventing the housing 22 from being too loose between the housing 22 and the second positioning part 112. This effectively improves the pressing efficiency of the pressing equipment 30 while ensuring the stability of the pressing equipment 30.

[0100] In some embodiments, see Figure 4 , Figure 5 and Figure 11 , Figure 11 yes Figure 4 A schematic diagram of one embodiment of the base assembly 500 is shown. The base assembly 500 includes: a base body 510, an adsorption member 520, and multiple support rods 530. One end of the support rod 530 is rotatably connected to the base body 510, and the axis of rotation of the support rod 530 relative to the base body 510 is perpendicular to the support plane of the base body 510; the adsorption member 520 is disposed at the other end of the support rod 530, and the adsorption member 520 is used to adsorb and adhere to the support plane. The multiple support rods 530 rotate relative to the base body 510 within the support plane, which can effectively increase the support area between the base body 510 and the support plane, thereby improving the support stability of the pressing equipment 30 and thus effectively improving the safety of the pressing equipment 30. Furthermore, an adsorption member 520 is also provided at one end of the support rod 530, which is used to adsorb and adhere to the support plane, thereby further improving the safety of the pressing equipment 30.

[0101] In summary, the pressing equipment 30 of this application includes a positioning component 100 and a pressing top component 200. The positioning component 100 is provided with a first positioning part 111 and a second positioning part 112, wherein the cover is limited to the first positioning part 111, and the end of the housing 22 used for connecting with the cover is limited to the second positioning part 112; the pressing top component 200 is disposed above the positioning component 100, and the pressing top component 200 and the positioning component 100 can move relative to each other along the pressing direction X1. In this way, the pressing top component 200 does not need to position the end of the housing 22 away from the cover, and can uniformly transmit the pressing force to the housing 22, thereby giving the pressing equipment 30 high pressing stability, improving the pressing yield of the housing 22 and the cover, and effectively reducing the number of processes for the housing 22 and the cover, thereby effectively improving the pressing efficiency of the housing 22 and the cover. Furthermore, the first positioning part 111 for the positioning plate 110 body and the second positioning part 112 for the positioning housing 22 are provided on the same component, that is, the first positioning part 111 and the second positioning part 112 are provided on the positioning assembly 100. When it is necessary to press-fit housings 22 and covers of different specifications and models, it is only necessary to replace the corresponding positioning assembly 100 to quickly perform the pressing process on the corresponding housings 22 and covers. Based on this, the number of change parts of the pressing equipment 30 when pressing different types of housings 22 and covers can be effectively reduced, thereby effectively reducing the pressing cost.

[0102] The above description is merely an embodiment of this application and does not limit the patent scope of this application.
