[0002] In battery manufacturing processes, such as electrolyte injection, negative pressure, negative pressure settling, and high-temperature immersion, traditional fixtures and equipment have some shortcomings. For example, frequent fixture disassembly may be required at different process stages, which not only increases operational complexity and time costs but may also affect the battery's sealing performance and process stability. Furthermore, existing fixtures also have deficiencies in terms of pressure holding performance, compatibility with different battery sizes, and ease of integration with functional workstations.

[0063] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0064] In the description of this application, it should be understood that the terms "upper," "lower," "left," "right," "front," "rear," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or relative positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this application. Unless otherwise specified, the above-mentioned orientational descriptions can be flexibly set in practical applications, provided that the relative positional relationships shown in the accompanying drawings are satisfied.

[0065] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0066] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "communication" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. They can refer to a direct connection or an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0067] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, article, or apparatus.

Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0069] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0070] In the series of complex processes in battery production, such as liquid injection, negative pressure, negative pressure settling, and high-temperature immersion, traditional fixtures and equipment have revealed many defects.

[0071] First, the frequent disassembly and reassembly of fixtures in various battery manufacturing processes is a significant problem. Because different processes have different requirements for fixtures, operators must frequently disassemble and reassemble them. This process is not only cumbersome and greatly increases operational complexity, but also consumes a significant amount of time, leading to low production efficiency.

[0072] More importantly, frequent disassembly and installation make it difficult to guarantee an ideal seal every time, thus affecting the battery's sealing performance. Poor sealing may allow external gases to enter the battery or leak electrolytes and other substances inside the battery, thereby disrupting the internal chemical environment and severely impacting the battery's process stability and the quality of the final product.

[0073] Secondly, insufficient pressure holding performance is another challenge faced by traditional fixtures. During battery production, especially in processes such as electrolyte injection and negative pressure application, fixtures need to provide a stable and reliable pressure holding environment. However, existing fixtures often fail to meet this requirement, potentially leading to problems such as unstable pressure and insufficient pressure holding time, which negatively impact battery performance and quality.

[0074] Furthermore, poor compatibility with different battery sizes is a major drawback of traditional fixtures. With the continuous development of battery technology, battery sizes and specifications are becoming increasingly diverse. Traditional fixtures are typically designed for batteries of specific sizes, and when faced with batteries of different sizes, they may not be able to provide adequate fixation and support, leading to unstable battery positions within the fixture and affecting the accuracy and consistency of the production process.

[0075] Finally, the lack of ease of docking with the docking device 200 is also a problem that urgently needs to be solved. In modern battery production lines, the fixture needs to dock with various docking devices 200, such as liquid injection equipment and negative pressure equipment. (See [link to relevant documentation]). Figure 16 as well as Figure 15 This allows for quick and accurate docking. However, existing fixtures have shortcomings in this regard; the docking process can be complex and time-consuming, impacting the overall operational efficiency of the production line.

[0076] To solve the above problem, see Figure 1 This application provides a handling fixture. The battery has an injection port. The handling fixture 100 includes a support structure 102 and at least one injection valve 101 connected to the support structure 102. The support structure 102 is adapted to support the battery. The injection valve 101 is adapted to block the injection port and is a normally closed valve.

[0077] Furthermore, the handling fixture is equipped with anti-collision blocks 500 and wear-resistant strips 600.

[0078] The wear-resistant strip 600 can be located on the bottom or side of the handling fixture; this application does not limit this.

[0079] Since the injection valve 101 is a normally closed valve, it automatically seals the injection port when the battery 300 is supported by the support structure 102. Throughout the loading process, even with changes in external pressure or process operations, the normally closed injection valve 101 can always maintain a seal on the injection port.

[0080] Meanwhile, during processes such as liquid injection, negative pressure, and formation, the normally closed liquid injection valve 101 prevents outside air from entering the battery 300 and also avoids gas leakage inside the battery 300. When the battery 300 is evacuated, the sealing effect of the liquid injection valve 101 maintains a vacuum state inside the battery 300, thereby achieving closed-loop pressure maintenance. This design also reduces the production cycle time during the liquid injection process of the battery 300.

[0081] The closed-loop pressure maintenance throughout the entire process ensures that each 300 battery undergoes liquid injection, negative pressure, and formation processes under the same pressure environment, improving production consistency. This improved production consistency helps guarantee the quality stability and reliability of the 300 battery products, reducing the defect rate.

[0082] In some embodiments, see Figure 1 The injection valve 101 includes a base 1011 and a seal 1012. The base 1011 is connected to the support structure 102, and the seal 1012 is disposed on the base 1011 and is adapted to seal the injection port.

[0083] The base 1011 serves as a support structure for the injection valve 101, connected to the bearing structure 102, providing a stable mounting base for the entire injection valve 101. The sealing element 1012 is disposed on the base 1011, and when the bearing structure 102 carries the battery 300, the sealing element 1012 can correspond to the injection port of the battery 300.

[0084] The seal 1012 is typically made of a material with good elasticity and sealing properties, such as rubber. Its shape and size are designed to match the injection port, and when the battery 300 is in the appropriate position, the seal 1012 can fit tightly against the injection port under a certain pressure.

[0085] This allows the battery 300 to automatically seal the liquid injection port during loading, eliminating the need for additional complex operations to ensure a seal. This simplifies the operation steps in the battery 300 production process, reduces the need for manual intervention, and improves production efficiency.

[0086] In some embodiments, the injection valve 101 further includes an external connector 1014, which is adapted to connect to a mating connector. When the external connector 1014 is connected to the mating connector, the injection valve 101 is open, and when the external connector 1014 is separated from the mating connector, the injection valve 101 is closed.

[0087] The working principle of the key components in this application is illustrated below.

[0088] The injection valve 101 is a normally closed shut-off valve. The structure of the injection valve 101 consists of two parts: a male head and a female head. They can be quickly plugged in and out of each other. When connected, fluid can flow through the valve. When disconnected, the valve can instantly seal and isolate the external environment. At the same time, some of the connectors can meet the requirements of high vacuum operating conditions.

[0089] The technical requirements for hydraulic quick couplings in this solution are: pressure resistance ≤ -0.101 MPa; mating life ≥ 180,000 cycles; mating pressure fluctuation ≤ 250 Pa; material must be 316 stainless steel.

[0090] See Figure 7 as well as Figure 8 , Figure 7 and Figure 8 The structure shown is a male head and a female head. It can be seen that there is a shaft inside the male head and the female head. They are normally closed. When the sleeve is pushed back, the retaining ball will float. The male head extends into the female head and the two shafts squeeze each other. The retaining ball enters the retaining groove. The sleeve rebounds and presses the retaining ball into the retaining groove, thus achieving interlocking. At this time, a passage is formed inside the male head and the female head, which can be used for vacuuming and liquid injection operations.

[0091] In this application, the mating of the male and female heads described above enables a quick connection and sealing between the injection needle head and the docking device 200 docking section.

[0092] When the battery 300 is placed in the clamp and the locking mechanism clamps the battery 300, the injection port of the battery 300 will press against the sealing gasket of the needle and maintain sufficient pre-tightening force, causing the sealing gasket to deform and thus achieving a seal with the outside environment. At this time, the inside of the battery 300 is only connected to the structure inside the injection needle. The other side of the injection needle is equipped with the male part of the hydraulic quick connector element. When not connected to the female part of the hydraulic quick connector, it can completely isolate the external environment and has sufficient pressure holding effect.

[0093] In some embodiments, the support structure 102 includes a support base 1021 and a support beam 1022, with the support beam 1022 disposed on the support base 1021 and the injection valve 101 disposed on the support beam 1022.

[0094] The support base 1021 provides a stable foundation for the entire support structure 102. It can evenly distribute the weight of the battery 300, preventing shaking or tilting during the support process. This is crucial for ensuring the positional accuracy of the battery 300 during the production process, especially in precision operations such as liquid injection, negative pressure, and formation. A stable support base helps improve the accuracy of the process.

[0095] In some embodiments, see continue to see Figure 1 and combined Figure 3The injection valve 101 is provided with a first limiting member 1015 and a second limiting member 1016 on opposite sides. The first limiting member 1015 and the second limiting member 1016 are fixed to the support beam 1022 and arranged along the length direction of the support beam 1022.

[0096] The injection valve 101 is installed between the two limiting members. Through contact with the first limiting member 1015 and the second limiting member 1016, the position of the injection valve 101 on the support beam 1022 can be fixed. This design utilizes the principle of mechanical limiting to prevent the injection valve 101 from shifting on the support beam 1022. Especially when vibration during equipment operation or the installation and removal of the battery 300 may cause the position of the injection valve 101 to change, it ensures that the injection valve 101 is always in an accurate working position and can be accurately aligned with the injection port of the battery 300.

[0097] In some embodiments, see Figure 5 as well as Figure 6 The application also includes a push assembly 103 (not shown in the figure), which is disposed opposite to the first docking valve. The battery 300 is adapted to be placed between the first docking valve and the push assembly 103. The push assembly 103 is adapted to drive the battery 300 to move toward the first docking valve so that the liquid inlet docks with the first docking valve.

[0098] The actuator 103 operates based on the principle of applying mechanical force. When docking of the battery 300 with the first docking valve is required, the actuator 103 is activated and generates a directional thrust acting on the battery 300. This thrust overcomes the friction that may exist between the battery 300 and the supporting structure 102, as well as the inertia of the battery 300 itself, causing the battery 300 to move smoothly along a predetermined straight trajectory toward the first docking valve. During this process, the lateral limiting and guiding of the battery 300 by the supporting structure 102 ensures that the battery 300 moves accurately toward the docking target until the liquid inlet of the battery 300 is tightly fitted with the first docking valve, achieving the docking state.

[0099] In some embodiments, the pushing assembly 103 includes a fixing member and a pushing member 1032, the pushing member 1032 being connected to the fixing member, and the pushing member 1032 having at least one pushing portion adapted to move toward the first docking valve, the pushing portion being adapted to push the battery 300 toward the first docking valve.

[0100] For example, the pusher 1032 is a pusher plate.

[0101] The special design of the propulsion unit enables it to form a fitting and stable contact with the surface of the battery 300. During the propulsion process, the movement direction and distance of the battery 300 are precisely controlled, guiding the electrolyte inlet of the battery 300 to connect with the first docking valve in an ideal posture. This avoids misalignment caused by uneven force or directional deviation, effectively ensuring the smooth progress of subsequent processes such as electrolyte injection and electrical connection, and improving production quality and stability.

[0102] In some embodiments, the number of pushers is equal to the number of first docking valves, and they are one-to-one. The pushers push the battery 300 to dock the liquid inlet with the first docking valve.

[0103] The number of actuating units is set to be equal to and one-to-one with the number of first docking valves. This layout is based on the principle of precise matching. When the actuating assembly 103 receives a drive command and begins to work, each actuating unit applies thrust to a corresponding first docking valve, ensuring that the battery 300 receives a balanced and precisely positioned thrust in all directions. This guarantees that the electrolyte inlet of the battery 300 moves accurately toward the corresponding first docking valve during movement, ultimately achieving perfect docking.

[0104] In some embodiments, the pusher 1032 includes a connecting base 1033 slidably connected to the fixing member, a locking plate adapted to move toward or away from the first docking valve, and at least one pusher is provided on the side of the locking plate near the first docking valve.

[0105] The pusher 1032 includes a drive member connected to the connecting base 1033 to drive the locking plate to move.

[0106] Correspondingly, by precisely controlling the moving distance, speed and direction of the locking plate through the drive components, it is possible to flexibly adjust to different specifications and models of batteries 300 and docking requirements under different working conditions.

[0107] In some embodiments, the pusher 1032 further includes at least one first floating member 1034, which is disposed between at least one pusher portion and the connecting base 1033.

[0108] The uniform force transmission achieved by the first floating component 1034 enhances the stability of the entire propulsion system. During the propulsion process, the battery 300 can move smoothly towards the first docking valve under uniform thrust, reducing swaying and vibration caused by uneven force. This not only helps to improve the docking success rate, but also reduces the interference caused by the swaying of the battery 300 to other equipment on the production line, ensuring the smooth operation of the production process.

[0109] In some embodiments, see Figure 12 as well as Figure 13The pusher 1032 also includes a latch 1035, which is located on the fixing member and is adapted to engage with the locking plate. When the locking plate moves to the first position, the pusher pushes the liquid injection port of the battery 300 to engage with the first docking valve, and the latch 1035 engages with the locking plate.

[0110] The engagement of the latch 1035 with the locking plate precisely defines the position of the locking plate, thereby ensuring the accuracy of the push unit's movement in aligning the battery 300's filler port with the first docking valve. Once the latch 1035 is successfully engaged, it means the locking plate is in the correct position to achieve optimal docking with the push unit, preventing inaccurate docking due to locking plate misalignment. This effectively improves the quality and consistency of the docking between the battery 300 and the first docking valve.

[0111] In some embodiments, see Figure 12 as well as Figure 13 The pusher 1032 also includes an unlocking member 1036, which is connected to the transport clamp 100. A locking plate is disposed between the latch 1035 and the unlocking member 1036, and the unlocking member 1036 is adapted to unlock the connection between the locking plate and the latch 1035.

[0112] The locking plate is located between the latch 1035 and the unlocking component 1036. In the normal docking state, the latch 1035 and the locking plate are fastened together, maintaining a stable docking state between the battery 300 filling port and the first docking valve. The unlocking component 1036 unlocks the connection between the latch 1035 and the locking plate through a specific mechanical structure or action.

[0113] Correspondingly, the latch 1035 is located between the fixing member and the locking plate, and the side of the latch 1035 facing the fixing member is rotatably connected to the fixing member.

[0114] The latch 1035 includes a buffer surface facing the locking plate. Along a first direction, the buffer surface includes a first end and a second end connected together. The first end is located in front of the second end. The first direction is the direction along the locking plate pointing towards the fixing member. And along a direction perpendicular to the first direction, the second end is lower than the first end.

[0115] The locking plate is adapted to slide along the first end of the buffer surface to the second end so that the latch 1035 rotates toward the fixing member.

[0116] Furthermore, the latch 1035 includes a rod, and along a direction perpendicular to the first direction, the bottom surface of the rod is higher than the second end, and the bottom surface of the rod is connected to the second end to form a latching surface. When the locking plate moves to the first position, the latch 1035 rotates away from the fixing member so that the latching surface latches with the side of the locking plate away from the pushing part.

[0117] In some embodiments, the unlocking member 1036 includes an unlocking surface adapted to slide along a first end of a buffer surface to a second end to rotate the latch 1035 toward the fixing member so that the latch 1035 unlocks the locking plate.

[0118] During the sliding process of the unlocking surface, due to its specific shape and the mechanical engagement with the latch 1035 and the fixing member, a force is applied to the latch 1035, causing it to rotate towards the fixing member. This allows the latch 1035 to unlock the locking plate.

[0119] Correspondingly, along the first direction, the buffer surface includes a third end and a fourth end connected together, with the third end located in front of the fourth end; and along a direction perpendicular to the first direction, the third end is higher than the fourth end.

[0120] In some embodiments, this application further includes a first driving part, which is disposed on the side of the locking plate away from the fixing member, and the first driving part is adapted to push the locking plate toward the fixing member.

[0121] It should be noted that the first driving part can be the force applied by the user to the locking plate.

[0122] In some embodiments, this application further includes an elastic element for applying an elastic force to the locking plate, the elastic force being used to move the locking plate.

[0123] During the process of aligning the battery 300's electrolyte inlet with the first docking valve, the elastic force applied by the elastic element acts as an auxiliary force to move the locking plate. Sometimes, relying solely on the power of the drive component may not be sufficient for precise fine-tuning of the locking plate's position; the presence of the elastic force can compensate for this.

[0124] In some embodiments, this application further includes at least one limiting structure for limiting at least one position of the battery 300 in the length direction.

[0125] The limiting structure precisely limits the specific position of the battery 300 in the length direction through its specific shape, size and the way it cooperates with related components such as the battery 300 and the support structure 102.

[0126] When the battery 300 is placed on the support structure 102 in preparation for subsequent operations (such as docking, liquid injection, etc.), the limiting structure interacts with the corresponding part of the battery 300 in the length direction according to its preset position and size.

[0127] For example, if the limiting structure is a slot, the edge of the battery 300 will be embedded in the slot, thereby limiting the movement of the battery 300 in the length direction and keeping it within a specific position range; if it is a positioning pin, the positioning pin will be inserted into the positioning hole reserved on the battery 300 casing, which also serves to limit the position of the battery 300.

[0128] Furthermore, the limiting structure includes a first limiting unit 104 and a second limiting unit 105. The first limiting unit 104 includes at least one first limiting member 1015, and the second limiting unit 105 includes at least one second limiting member 1016. The first limiting unit 104 and the second limiting unit 105 are capable of relative movement along a second direction.

[0129] In some embodiments, see Figure 2 The support member 107 includes a plurality of guide posts 106 spaced apart along a second direction. The battery 300 is housed between two adjacent first guide posts 106. The second direction is perpendicular to the direction of the locking plate pointing to the first docking valve.

[0130] Multiple guide posts 106 are spaced apart along a second direction to form a frame-like structure. When the battery 300 is placed on the support structure 102, it is accommodated between two adjacent first guide posts 106. Since the second direction is perpendicular to the direction of the locking plate pointing to the first docking valve, these guide posts 106 mainly function in the direction perpendicular to the docking movement direction of the battery 300.

[0131] In some embodiments, a support member 107 is also included, which is disposed between the locking plate and the first docking valve, and is adapted to support the battery 300.

[0132] In some embodiments, this application also includes a handling system, which includes a handling fixture 100 and a docking device 200, wherein the battery 300 is connected to the docking device 200 via a first docking valve.

[0133] The support member 107 is located between the locking plate and the first docking valve, and its main function is to provide a stable support platform for the battery 300. Through its own structural design, it contacts the bottom or side of the battery 300 (depending on the specific support method), bears the weight of the battery 300, and steadily supports the battery 300 at a suitable height and position.

[0134] The shape, size, and surface characteristics of the support 107 are carefully designed according to the external features of the battery 300 and the requirements of the manufacturing process. For example, if the bottom of the battery 300 is flat, the support 107 may adopt a flat plate structure to provide uniform support over a large area; if the sides of the battery 300 need support, the support 107 may be designed as an arc-shaped structure that matches the curvature of the side of the battery 300 to ensure a tight fit and thus achieve stable support.

[0135] In some embodiments, see Figure 10 The docking device 200 is equipped with a fluid pipeline, which is suitable for switching between the injection machine and the negative pressure machine.

[0136] The fluid piping in the docking device 200 is designed with switchable connections, which is typically achieved through special combinations of valves, fittings, or switching mechanisms. For example, a three-way valve or a multi-way valve may be used, with different ports of the valve connected to the injection machine, the negative pressure machine, and related components within the docking device 200 that are connected to the battery 300.

[0137] When liquid injection is required, the liquid injection machine is connected to the corresponding battery 300 in the docking device 200 by operating the valve or switching mechanism. The electrolyte and other fluids in the liquid injection machine can then flow into the battery 300 under pressure through the fluid pipeline.

[0138] When negative pressure operation is required, the fluid pipeline is switched to be connected to the negative pressure machine by operating the valve or switching mechanism. At this time, the negative pressure machine draws a vacuum inside the battery 300 through the fluid pipeline to form a negative pressure environment to meet the negative pressure process requirements in the battery 300 production process.

[0139] In some embodiments, the docking device 200 includes a second docking valve adapted to dock with a first docking valve and adapted to form a sealing state to prevent the passage or leakage of fluid.

[0140] The docking of the second docking valve and the first docking valve is achieved based on a precise mechanical structural match. The two valves are designed with mutually compatible interface shapes, sizes, and connection methods. During the docking operation, the driving action of components such as push assembly 103 ensures that the second docking valve can accurately fit together with the first docking valve, forming a tight connection.

[0141] Furthermore, the second docking valve is suitable for achieving a high vacuum state with a minimum absolute vacuum of 40 Pa.

[0142] In some embodiments, this application also includes a floating structure 400 connected to the second docking valve, the floating structure 400 being adapted to correct the position of the second docking valve.

[0143] During the docking process between the second docking valve and the first docking valve, factors such as equipment vibration, installation errors, and deviations in the placement of the battery 300 may cause the initial position of the second docking valve to deviate slightly from the ideal docking position.

[0144] At this time, the elastic element in the floating structure 400 will undergo elastic deformation due to the action of external force, and push or pull the second docking valve to make fine adjustments in a certain direction through the action of elastic force; or the sliding and rotating connecting parts allow the second docking valve to move or rotate within a small range in the corresponding degree of freedom, thereby correcting the position of the second docking valve and making it closer to the ideal docking position.

[0145] In some embodiments, the floating structure includes a fixed block 401, through which a second docking valve passes, and the fixed block is provided with a receiving space.

[0146] See Figure 9 The floating structure also includes a floating element 402, which is disposed within the accommodating space and connected to the second docking valve around the periphery of the second docking valve.

[0147] For example, the floating element 402 is a spring.

[0148] The fixed block serves as the foundational support for the floating structure, providing a relatively fixed installation position and framework for the entire structure. The second docking valve penetrates the fixed block, allowing the block to position and constrain the valve, limiting its excessive movement perpendicular to the penetration direction.

[0149] In some embodiments, see Figure 14 as well as Figure 17 , Figure 18 The docking device 200 is either a liquid injection device 218 or a vacuum pumping device 219.

[0150] When the docking device 200 is used as a liquid injection device, its core function is to accurately inject a specific liquid (usually electrolyte) into the battery 300. It achieves a tight connection with the battery 300 through docking structures (such as a first docking valve, a second docking valve, etc.) to ensure the formation of a sealed channel during the liquid injection process and prevent electrolyte leakage.

[0151] The docking device 200 has the dual functions of an electrolyte injection device and a vacuuming device, greatly improving its applicability in the battery 300 production process. In different stages of battery 300 manufacturing, it can perform electrolyte injection operations to accurately inject electrolyte into the battery 300, laying the foundation for the battery 300's electrochemical performance; it can also perform vacuuming operations to create a suitable negative pressure environment inside the battery 300, facilitating the smooth progress of subsequent processes (such as formation).

[0152] In some embodiments, the docking device 200 docking assembly comprises a sub-assembly base 201, a height adjustment component 203 mounting base 202, a height adjustment component 203, a component mounting plate 204, a solenoid valve 205, an adjusting bolt 206, a cover plate 207, a guide shaft 208, an oil-free bushing 209, a mounting base 210, a mounting base plate 211, a propulsion cylinder 212, a floating joint 213, a propulsion connecting rod 214, a disengaging cylinder 215, a disengaging plate 216, and a docking joint assembly 217.

[0153] See Figure 10 as well as Figure 11 , Figure 14 as well as Figure 16 The functional workstation docking assembly consists of a base 201, a height adjustment component mounting seat 202, a height adjustment component 203, a component mounting plate 204, a solenoid valve 205, an adjusting bolt 206, a cover plate 207, a guide shaft 208, an oil-free bushing 209, a mounting base 210, a mounting base plate 211, a propulsion cylinder 212, a floating joint 213, a propulsion connecting rod 214, a prying cylinder 215, a prying plate 216, and a docking joint assembly 217.

[0154] The sub-base 201 serves as a basic component, and the height adjustment component mounting base 202 is mounted on the sub-base 201 to provide an installation position for the height adjustment component 203. They may be fixed together by bolts or other connecting parts to ensure that the height adjustment component mounting base 202 is in a stable position on the sub-base 201.

[0155] The height adjustment component 203 is mounted on the height adjustment component mounting base 202, and its top end is connected to the component mounting plate 204. The height of the component mounting plate 204 can be changed by the height adjustment component 203, which may be achieved through a threaded structure or hydraulic means.

[0156] The solenoid valve 205 is mounted on the component mounting plate 204 and fixed by mounting holes and bolts, etc., and is used to control the flow of fluids (such as gas and liquid). The adjusting bolt 206 is also mounted on the component mounting plate 204 and is used to further fine-tune the position or tension parameters of related components.

[0157] The guide shaft 208 is mounted on the mounting base 210 or other support structure via an oil-free bushing 209. The oil-free bushing 209 reduces friction and provides guidance, enabling the guide shaft 208 to move smoothly in a linear fashion. The mounting base 210 and the mounting plate 211 cooperate with each other to provide a stable bottom support structure for the entire device.

[0158] The propulsion cylinder 212 is installed on the mounting base plate 211 or other suitable location. The piston end of the propulsion cylinder 212 is connected to the propulsion connecting rod 214 via a floating joint 213. The floating joint 213 can compensate for a certain angular deviation, ensuring that the propulsion force can be effectively transmitted to the propulsion connecting rod 214. The deflecting cylinder 215 is also installed in a suitable location, and its piston end is connected to the deflecting plate 216 for performing the deflecting action.

[0159] The mating connector assembly 217 is installed in the appropriate position and may connect to other components that require mating. The specific connection method depends on the mating requirements and may include various methods such as plug-in or threaded connections. The cover plate 207 is installed on the outside of the entire device to protect the internal components and for aesthetic purposes. It is connected to other components by bolts or clips.

[0160] When it is necessary to adjust the height of the component mounting plate 204, operate the height adjustment assembly 203. For example, if the height adjustment assembly 203 is threaded, the telescopic part of the height adjustment assembly 203 can be extended or retracted by rotating the adjusting bolt, thereby changing the height of the component mounting plate 204 to adapt to different working requirements, such as matching the docking height with other equipment.

[0161] Solenoid valve 205 controls the opening and closing of the fluid passage according to the signal from the control system. For example, in an automated production line, when it is necessary to drive the cylinder to move, solenoid valve 205 opens the corresponding air passage, allowing compressed air to enter the cylinder and drive the piston to move.

[0162] After receiving a pneumatic pressure signal, the piston in the propulsion cylinder 212 extends or retracts under the action of pneumatic pressure. The force is transmitted through the floating joint 213 and the propulsion connecting rod 214 to achieve the function of driving other components to perform linear motion, such as pushing products or other tooling fixtures for position adjustment or docking operations.

[0163] When the cylinder 215 is working, the piston drives the prying plate 216 to move, which pries apart the parts that need to be separated or positioned. For example, in the product assembly process, adjacent parts are pried apart by a certain distance in order to carry out the next assembly operation.

[0164] Throughout the movement of the device, the guide shaft 208, guided by the oil-free bushing 209, ensures that the moving parts move linearly in a predetermined direction, preventing skewness and guaranteeing the accuracy and stability of the movement. For example, during the process of the propulsion cylinder 212 pushing the propulsion connecting rod 214, the guide shaft 208 provides precise motion guidance for the relevant components.

[0165] With the cooperation of other components, such as being pushed to the appropriate position by the propulsion cylinder 212, the docking joint assembly 217 connects with the docking components of other equipment to realize the docking between products or tooling fixtures, and complete functions such as the transmission of liquids, gases, signals, or mechanical connections.

[0166] The mating connector assembly 217 consists of a hydraulic quick-connect female connector, a connector mounting block, a functional pipeline connector, an assembly mounting block, an assembly fixing block, an assembly connecting block, a spring, a lock nut, and functional pipelines.

[0167] In the system of this invention, the flow clamp part can be transported as a whole with the conveyor line, while the docking device 200 docking assembly is fixed in a fixed position. When the pipeline of the docking device 200 docking assembly is connected to the injection circuit and the injection pump, it is used as an injection machine; when the pipeline of the docking device 200 docking assembly is connected to the vacuum circuit, it can be used as a negative pressure machine.

[0168] When the battery 300 is placed in the fixture, it is in position one. The locking part is engaged and clamped, and the battery 300's liquid injection hole presses against the pressure-holding connector assembly, so that the battery 300 is in position two, completing the clamping, positioning and sealing of the battery 300. After the battery 300 is processed, the locking part is engaged and clamped, and the battery 300 loses its restraint and can be easily removed.

[0169] Locking mechanism with switch clip principle: When the clip is closed, push the locking plate, then push the part to contact the battery 300, continue to push the locking plate, and then the locking plate will make contact.

[0170] Continue pushing to rotate the wedge block of the automatic locking latch 1035 clockwise. When the plane of the locking plate coincides with the hook surface of the automatic locking latch 1035, the wedge block of the automatic locking latch 1035 returns to its original position counterclockwise under the action of the spring. At this time, the automatic locking latch 1035 locks with the locking plate, completing the locking mechanism.

[0171] During the clamping process, the wedge block of the clamping device is advanced horizontally until it contacts the wedge block of the automatic locking buckle 1035. The advancement continues, causing the wedge block of the automatic locking buckle 1035 to rotate clockwise until the hook surface of the wedge block disengages from the contact surface of the locking plate. At this point, the tension spring drives the guide rod to retract, the locking plate pops out and resets, completing the clamping and unlocking process of the locking mechanism.

[0172] The docking process consists of the following steps:

[0173] Initial state adjustment: After the flow fixture is in place and positioned, the cylinder retracts, causing the pusher plate 216 to retract. When the pusher plate 216 contacts the hydraulic quick connector female head, its annular structure causes the outer ring of the hydraulic quick connector female head to retract, at which point the female head is in the released state.

[0174] During the docking process, the cylinder extends, causing the docking connector assembly 217 to extend forward. This continues until the pressure-holding connector assembly is engaged, and the hydraulic quick-connect coupling completes the connection between the battery 300 and the functional pipeline.

[0175] In the locked state, the cylinder extends, causing the release plate 216 to extend, interlocking the male and female heads of the hydraulic quick-connect coupling, thus locking the entire structure in position. Due to the performance of the hydraulic quick-connect coupling, it can be considered completely sealed and leak-free before and after docking, completing a pressure-holding, sealed, and rapid docking.

[0176] During the separation process, after the functional processes (liquid injection, negative pressure) are completed, the cylinder retracts, causing the disengaging plate 216 to retract as well. When the disengaging plate 216 contacts the female head of the hydraulic quick-connect coupling, its annular structure causes the outer ring of the female head to retract, at which point the female head is in a released state. Subsequently, the cylinder retracts, causing the docking connector assembly 217 to retract backward, separating from the pressure-holding connector assembly and quickly disengaging from the docking. After the docking is released, the interlocking sealing connector instantly resets and closes upon pressurization to prevent air from entering, providing sufficient automatic sealing capability. The equipment then resets, ready for the next docking attempt.

[0177] Specific combination Figure 1 as well as Figure 10 The following describes the clamping and fixing of battery 300: When battery 300 is placed in the fixture, it is in position one. The locking part closes the clamp, and the liquid injection hole of battery 300 presses against the pressure-holding connector assembly, so that battery 300 is in position two, completing the clamping, positioning and sealing of battery 300; After battery 300 is processed, the locking part opens the clamp, and battery 300 loses its restraint and can be easily removed.

[0178] When closing the clamp, push the locking plate, and then the pushing part contacts the battery 300. Continue to push the locking plate, and then the locking plate contacts the automatic latch 1035. Continue to push to make the wedge block of the automatic latch 1035 rotate clockwise until the pushing plane of the locking plate coincides with the hook surface of the automatic latch 1035. At this time, the wedge block of the automatic latch 1035 returns to its original position counterclockwise under the action of the spring. At this time, the automatic latch 1035 locks with the locking plate, and the locking part is installed and closed.

[0179] During the opening process, after the wedge-shaped part of the opening device is inserted, the wedge block of the opening device is advanced horizontally until it contacts the wedge block of the automatic locking buckle 1035. The advancement continues, causing the wedge block of the automatic locking buckle 1035 to rotate clockwise until the hook surface of the wedge block of the automatic locking buckle 1035 disengages from the contact surface of the locking plate. At this point, the tension spring drives the guide rod to retract, the locking plate pops out and resets, completing the opening and closing of the locking mechanism.

[0180] Battery 300 pressure holding: When the battery 300 is placed in the clamp and the locking part is installed to clamp the battery 300, the injection hole of the battery 300 will press against the needle sealing gasket and maintain sufficient pre-tightening force, causing the sealing gasket to deform, thereby achieving the function of sealing with the outside. At this time, the inside of the battery 300 is only connected to the injection needle.

[0181] Therefore, this application eliminates the need to disassemble the clamps during the injection, negative pressure, negative pressure settling, and high-temperature immersion processes, and has the following characteristics:

[0182] Battery 300 maintains pressure throughout the entire process: During loading, the battery 300 maintains pressure throughout the entire process. After the cell is fixed in the fixture, it remains in a closed, sealed state throughout the handling and process actions (liquid injection, negative pressure, formation). After sufficient vacuum is drawn into the battery 300, the negative pressure settling process can be directly initiated without the need for a separate negative pressure chamber, simplifying the equipment design and optimizing cycle time. Furthermore, the fully closed design ensures that the battery 300 remains in a negative pressure formation state during handling after negative pressure is applied, saving cycle time, eliminating process pins, simplifying the design, optimizing costs, and ensuring more consistent process performance across different batches of cells.

[0183] Quick docking and sealing: During liquid injection or negative pressure, the connector on the clamp and the docking device 200 can be directly and quickly docked to complete the circuit. Positioning is convenient. After the docking is loosened, the interlocking sealing connector instantly resets and closes when the pressure is increased to prevent air from entering. It has sufficient automatic sealing capability, saves equipment and cycle time, and belongs to the cupless liquid injection method, which can achieve the same effect as cup liquid injection without positive pressure pipeline.

[0184] Adaptable to high-temperature formation: The fixture can be moved into the high-temperature formation chamber and high-temperature formation can be carried out directly without disassembly. With high vacuum pressure holding, it can even directly form high-temperature and high-pressure formation. The operation is convenient and saves time, while the processed battery 300 process performance is better.

[0185] After the battery cell is installed, the clamp can maintain a high vacuum of at least 40 Pa after the vacuum is drawn.

[0186] The mobile fixture enables the fixture to be moved and transported. The overall structure of the mobile fixture is relatively lightweight. The frame structure forms a large enough plane to facilitate transport via the conveyor line. The bottom is equipped with wear-resistant baffles and anti-collision blocks, which play a buffering role during movement. The parts are made of wear-resistant materials and are easy to assemble. They replace the mechanism to bear wear and are easy to disassemble and replace.

[0187] This application also has the following advantages in terms of compatibility with different 300-cell battery sizes:

[0188] (1) Adjustable clamps, the limiting members may have an adjustable structure. For example, by connecting the moving member and the limiting member, the moving member can drive the limiting member to move within a certain range, thereby adapting to batteries 300 of different lengths.

[0189] The limiting component itself may have an adjustable clamping part that can be adjusted according to the width or thickness of the battery 300 to ensure that it can provide appropriate clamping force and fixation effect for batteries 300 of different sizes.

[0190] (2) The frame has a compatible design and may have sufficient space and a universal design. Its internal structure can accommodate batteries 300 of different sizes, and the layout takes into account the adaptation of different battery 300 sizes. For example, the frame may be equipped with adjustable positioning structures, such as guide post compatible adjustment plates, etc. By adjusting the position of these structures, it can adapt to batteries 300 of different diameters or shapes.

[0191] (3) Regarding the ease of docking with the docking device 200, the fixture may be equipped with quick-connect couplings. These couplings are specially designed, such as hydraulic quick couplings, to enable quick plug-in and plug-out connections with the docking device 200. When the fixture is moved to the vicinity of the docking device 200, the couplings can quickly dock with the corresponding pipelines or equipment, reducing docking time.

[0192] (4) The mating joint may have automatic alignment and locking functions. For example, during the mating process, the joint can automatically adjust its position to ensure accurate connection, and can automatically lock after connection to prevent accidental detachment and improve the convenience and reliability of mating.

[0193] (5) Standardized valves

[0194] The fixture's valves may employ a standardized design. Whether docking with injection equipment, vacuum equipment, or other docking devices, a unified standard is followed. This avoids docking difficulties caused by interface incompatibility and improves the fixture's versatility and ease of docking across different workstations.

[0195] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
