[0064] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0065] In the description of this application, it should be understood that the terms "upper", "lower", "left", "right", "front", "back", "inside", "outside", etc. indicate directions or positional relationships based on the directions or relative positional relationships shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on this application. Unless otherwise specified, the above-mentioned directional description can be flexibly set in the process of actual application under the condition that the relative positional relationship shown in the accompanying drawings is met.

[0066] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0067] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. It can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0068] In the present application, the terms "comprises", "comprising" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, article or device. In the absence of further restrictions, an element defined by the sentence "comprising a ..." does not exclude the presence of other identical elements in the process, article or device including the element.

[0069] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0070] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0071] In a series of complex process links in battery production, such as liquid injection, negative pressure, negative pressure standing and high temperature immersion, traditional fixtures and equipment expose many defects.

[0072] First, in the process of battery production, frequent disassembly of fixtures in various processes is a significant problem. Due to the different requirements of different processes for fixtures, operators have to frequently disassemble and reinstall fixtures. This process is not only cumbersome and greatly increases the complexity of the operation, but also consumes a lot of time, resulting in low production efficiency.

[0073] More importantly, frequent disassembly and installation operations make it difficult to achieve the ideal sealing effect every time, thus affecting the sealing performance of the battery. Poor sealing may cause external gas to enter the battery, or electrolyte and other substances inside the battery to leak, thereby destroying the chemical environment inside the battery, seriously affecting the process stability of the battery and the quality of the final product.

[0074] Secondly, the lack of pressure holding performance is also one of the challenges faced by traditional fixtures. In the battery production process, especially in the process links such as liquid injection and negative pressure, the fixture is required to provide a stable and reliable pressure holding environment. However, existing fixtures often find it difficult to meet this requirement, and may have problems such as unstable pressure and insufficient pressure holding time, which will have a negative impact on the performance and quality of the battery.

[0075] Furthermore, poor compatibility with different battery sizes is also a major drawback of traditional fixtures. With the continuous development of battery technology, the size and specifications of batteries are becoming increasingly diverse. Traditional fixtures are usually designed for batteries of specific sizes. When faced with batteries of different sizes, they may not be able to provide appropriate fixation and support, resulting in an unstable position of the battery in the fixture, affecting the accuracy and consistency of the production process.

[0076] Finally, the lack of convenience in docking with the docking device 200 is also a problem that needs to be solved. In a modern battery production line, the clamp needs to be docked with various docking devices 200, such as liquid injection equipment, negative pressure equipment, etc. Fig.16 as well as Fig.15 , for fast and accurate docking. However, existing fixtures have defects in this regard, and the docking process may be complicated and time-consuming, affecting the operating efficiency of the entire production line.

[0077] To solve the above problems, see Figure 1 The present application provides a handling fixture, the battery has a liquid injection port, the handling fixture 100 includes a bearing structure 102 and at least one liquid injection valve 101 connected to the bearing structure 102, the bearing structure 102 is suitable for bearing the battery, the liquid injection valve 101 is suitable for blocking the liquid injection port, and the liquid injection valve 101 is a normally closed valve.

[0078] Furthermore, an anti-collision block 500 and a wear-resistant strip 600 are provided on the handling fixture.

[0079] The wear strip 600 may be located at the bottom of the transport fixture or at the side of the transport fixture, and this application does not limit this.

[0080] Since the injection valve 101 is a normally closed valve, the injection valve 101 will automatically block the injection port when the battery 300 is supported by the supporting structure 102. During the entire loading process, even if there are external pressure changes or process operations, the normally closed injection valve 101 can always keep the injection port sealed.

[0081] At the same time, during the process of liquid injection, negative pressure, formation, etc., the normally closed liquid injection valve 101 can prevent the outside air from entering the battery 300, and also prevent the gas leakage inside the battery 300. When the battery 300 is evacuated, due to the sealing effect of the liquid injection valve 101, the inside of the battery 300 can maintain a vacuum state, thereby achieving closed-mouth pressure maintenance, and such a setting can reduce the production cycle during the liquid injection process of the battery 300.

[0082] The whole process of closed-mouth pressure maintenance can ensure that each battery 300 is injected, negative pressure, formed and other process operations under the same pressure environment, which improves the consistency of production. The improvement of production consistency helps to ensure the quality stability and reliability of the battery 300 product and reduce the defective product rate.

[0083] In some embodiments, see Figure 1 The injection valve 101 includes a base 1011 and a sealing member 1012 . The base 1011 is connected to the supporting structure 102 . The sealing member 1012 is disposed on the base 1011 , and the sealing member 1012 is suitable for sealing the injection port.

[0084] The base 1011 is connected to the bearing structure 102 as a supporting structure of the injection valve 101, providing a stable installation foundation for the entire injection valve 101. The sealing member 1012 is arranged on the base 1011, and when the bearing structure 102 carries the battery 300, the sealing member 1012 can correspond to the injection port of the battery 300.

[0085] The seal 1012 is usually made of a material with good elasticity and sealing properties, such as rubber, etc. Its shape and size are designed to match the liquid injection port. When the battery 300 is in a suitable position, the seal 1012 can fit tightly with the liquid injection port under a certain pressure.

[0086] In this way, the battery 300 can automatically seal the liquid injection port during the loading process without additional complicated operations to ensure the sealing. This simplifies the operation steps in the production process of the battery 300, reduces the need for manual intervention, and improves production efficiency.

[0087] In some embodiments, the injection valve 101 further includes an external connector 1014, which is suitable for connecting to a mating connector. When the external connector 1014 is connected to the mating connector, the injection valve 101 is opened, and when the external connector 1014 is separated from the mating connector, the injection valve 101 is closed.

[0088] The working principles of the key components in this application are exemplified below.

[0089] The injection valve 101 is a normally closed stop valve. The structure of the injection valve 101 is divided into two parts, a male head and a female head, which can be quickly plugged in and out of each other. When connected, the fluid can flow, and when separated, it can be instantly sealed and isolated from the external environment. At the same time, some joints can meet the use scenarios of high vacuum conditions.

[0090] The technical requirements of this plan for hydraulic quick connectors are: pressure resistance ≤-0.101Mpa; plug-in life ≥180,000 times; plug-in pressure fluctuation ≤250pa; the material must be 316 stainless steel.

[0091] See also 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 an axis inside the male head and the female head, and they are both normally closed. When the sleeve is pushed back, the card bead will float, and the male head will extend into the female head and the two axes will squeeze each other. The card bead enters the card slot and the sleeve rebounds. The sleeve presses the card bead into the card slot to achieve interlocking. At this time, a passage is formed inside the male head and the female head, and this passage can be used for vacuuming and liquid injection operations.

[0092] In the present application, the cooperation between the male head and the female head mentioned above can realize the quick connection and sealing between the injection needle head assembly and the docking assembly of the docking device 200.

[0093] When the battery 300 is placed in the fixture and the locking part is installed to clamp the battery 300, the injection hole of the battery 300 will press against the needle seal pad and maintain sufficient pre-tightening force to deform the seal pad, thereby achieving the effect of sealing with the outside world. At this time, the inside of the battery 300 is only connected to the structure inside the injection needle. The male part of the hydraulic quick connector element is installed on the other side of the injection needle. When it is not connected to the female part of the hydraulic quick connector, it can completely isolate the external environment and have a sufficient pressure-maintaining effect.

[0094] In some embodiments, the supporting structure 102 includes a supporting base 1021 and a supporting beam 1022 . The supporting beam 1022 is disposed on the supporting base 1021 , and the injection valve 101 is disposed on the supporting beam 1022 .

[0095] The bearing base 1021 provides a stable foundation for the entire bearing structure 102. It can evenly distribute the weight of the battery 300 to prevent shaking or tilting during the bearing process. This is very important to ensure the position accuracy of the battery 300 during the production process, especially in precision process operations such as injection, negative pressure, and formation. A stable bearing foundation helps to improve the accuracy of the process.

[0096] In some embodiments, see Figure 1 Combined with Figure 3A first limit member 1015 and a second limit member 1016 are provided on opposite sides of the injection valve 101 . The first limit member 1015 and the second limit member 1016 are fixed to the support beam 1022 and arranged along the length direction of the support beam 1022 .

[0097] The injection valve 101 is installed between the two limiters, and the position of the injection valve 101 on the support beam 1022 can be ensured to be fixed by contacting the first limiter 1015 and the second limiter 1016. This design utilizes the principle of mechanical limiter to prevent the injection valve 101 from being displaced on the support beam 1022, especially when the position of the injection valve 101 may be changed due to vibration during the operation of the equipment, loading and unloading of the battery 300, etc., to ensure 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.

[0098] In some embodiments, see Figure 5 as well as Figure 6 The present application also includes a pushing component 103 (not shown in the figure), which is arranged opposite to the first docking valve. The battery 300 is suitable for being placed between the first docking valve and the pushing component 103. The pushing component 103 is suitable for driving the battery 300 to move toward the first docking valve so that the docking port docks with the first docking valve.

[0099] The pushing component 103 operates based on the principle of applying mechanical force. When the battery 300 needs to be docked with the first docking valve, the pushing component 103 starts 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 and the inertia of the battery 300 itself, and prompts the battery 300 to move smoothly along a predetermined straight line trajectory toward the first docking valve. In this process, the lateral limit and guidance of the battery 300 by the supporting structure 102 ensures that the battery 300 moves accurately toward the docking target until the docking interface of the battery 300 is tightly fitted with the first docking valve to achieve a docking state.

[0100] In some embodiments, the pushing assembly 103 includes a fixing member and a pushing member 1032, the pushing member 1032 is connected to the fixing member, and the pushing member 1032 is provided with at least one pushing portion suitable for moving toward the first docking valve, and the pushing portion is suitable for pushing the battery 300 toward the first docking valve.

[0101] Exemplarily, the pushing member 1032 is a pushing plate.

[0102] The special design of the pushing part enables it to form a fit and stable contact state with the surface of the battery 300. During the pushing process, the moving direction and distance of the battery 300 are accurately controlled, guiding the battery 300 to dock with the first docking valve in an ideal posture, avoiding docking misalignment due to uneven force and directional deviation, and effectively ensuring the smooth implementation of subsequent processes such as electrolyte injection and electrical connection, thereby improving production quality and stability.

[0103] In some embodiments, the number of the pushing parts is equal to the number of the first docking valves and they are opposite to each other. The pushing parts push the battery 300 so that the docking port docks with the first docking valve.

[0104] The number of the push parts and the number of the first docking valves are set to be equal and one-to-one. This layout is based on the principle of precise matching. When the push component 103 receives a drive instruction and starts working, each push part will apply a thrust to a corresponding first docking valve, so that the battery 300 can be subjected to a balanced and precisely positioned thrust in all directions. This ensures that the docking port of the battery 300 moves accurately in the direction of the corresponding first docking valve during the movement, and finally achieves perfect docking.

[0105] In some embodiments, the pusher 1032 includes a connection base 1033 slidably connected to the fixing member, the locking plate is suitable for moving toward or away from the first docking valve, and at least one pusher is disposed on a side of the locking plate close to the first docking valve.

[0106] The pushing member 1032 includes a driving member, which is connected to the connecting base 1033 to drive the locking plate to move.

[0107] Correspondingly, the moving distance, speed and direction of the locking plate are precisely controlled by the driving member, so that flexible adjustments can be made according to the docking requirements of batteries 300 of different specifications and models and under different working conditions.

[0108] In some embodiments, the pushing member 1032 further includes at least one first floating member 1034 , and the at least one first floating member 1034 is disposed between the at least one pushing portion and the connecting base 1033 .

[0109] The uniform force transmission achieved by the first floating member 1034 enhances the stability of the entire pushing system. During the pushing process, the battery 300 can move smoothly toward the first docking valve under uniform thrust, reducing the shaking and vibration caused by uneven force. This not only helps to improve the success rate of docking, but also reduces the interference caused by the shaking of the battery 300 to other equipment on the production line, ensuring the smooth progress of the production process.

[0110] In some embodiments, see Fig.12 as well as Fig.13The push member 1032 also includes a lock 1035, which is arranged on the fixing member. The lock 1035 is suitable for buckling with the locking plate. When the locking plate moves to the first position, the push block pushes the docking port of the battery 300 to dock with the first docking valve, and the lock 1035 is buckled with the locking plate.

[0111] The buckle 1035 and the locking plate can accurately define the position of the locking plate, thereby ensuring the accuracy of the push block pushing the battery 300 to dock with the first docking valve. Once the buckle 1035 is successfully buckled, it means that the locking plate is in the correct position for the push block to achieve the best docking effect, avoiding the situation where the push block pushes the battery 300 due to the position deviation of the locking plate, which effectively improves the quality and consistency of the docking between the battery 300 and the first docking valve.

[0112] In some embodiments, see Fig.12 as well as Fig.13 The pushing member 1032 also includes an unlocking member 1036 , which is connected to the transport fixture 100 , and the locking plate is disposed between the lock buckle 1035 and the unlocking member 1036 , and the unlocking member 1036 is suitable for unlocking the connection between the locking plate and the lock buckle 1035 .

[0113] The locking plate is located between the lock buckle 1035 and the unlocking member 1036. In the normal docking state, the lock buckle 1035 and the locking plate are buckled together to maintain the stable state of the battery 300 docking interface and the first docking valve. The unlocking member 1036 unlocks the connection between the lock buckle 1035 and the locking plate through a specific mechanical structure or action mode.

[0114] Correspondingly, the lock buckle 1035 is disposed between the fixing member and the locking plate, and the lock buckle 1035 is rotatably connected to the fixing member at one side facing the fixing member.

[0115] The lock buckle 1035 includes a buffer surface facing the locking plate. Along the first direction, the buffer surface includes a first end and a second end connected to each other, the first end is located in front of the second end, and the first direction is the direction along the locking plate pointing to the fixing member; and along the direction perpendicular to the first direction, the second end is lower than the first end.

[0116] The locking plate is suitable for sliding along the first end toward the second end of the buffer surface to allow the lock buckle 1035 to rotate toward the fixing member.

[0117] Furthermore, the lock 1035 includes a rod body, and along a direction perpendicular to the first direction, the bottom surface of the rod body is higher than the second end, and the bottom surface of the rod body is connected to the second end to form a buckling surface. When the locking plate moves to the first position, the lock 1035 rotates away from the fixing member so that the buckling surface is buckled with the side of the locking plate away from the push block.

[0118] In some embodiments, the unlocking member 1036 includes an unlocking surface, which is suitable for sliding along the first end to the second end of the buffer surface to rotate the lock buckle 1035 toward the fixing member, so that the lock buckle 1035 unlocks the locking plate.

[0119] During the sliding process of the unlocking surface, due to its specific shape and the mechanical matching relationship between the lock buckle 1035 and the fixing member, a force is applied to the lock buckle 1035, causing the lock buckle 1035 to rotate toward the fixing member, so that the lock buckle 1035 unlocks the locking plate.

[0120] Correspondingly, along the first direction, the buffer surface includes a third end and a fourth end connected to each other, the third end is located in front of the fourth end; and along the direction perpendicular to the first direction, the third end is higher than the fourth end.

[0121] In some embodiments, the present application further includes a first driving portion, which is disposed on a side of the locking plate away from the fixing member, and the first driving portion is suitable for pushing the locking plate to move toward the fixing member.

[0122] It should be noted that the first driving part may be the force applied by the user himself to the locking plate.

[0123] In some embodiments, the present application further includes an elastic member for applying an elastic force to the locking plate, and the elastic force is used to drive the locking plate to move.

[0124] In the process of pushing the battery 300 to dock with the first docking valve, the elastic force exerted by the elastic member can be used as an auxiliary power to drive the locking plate to move. Sometimes, it may not be possible to accurately fine-tune the position of the locking plate by relying solely on the power of the driving member, and the existence of the elastic force can make up for this.

[0125] In some embodiments, the present application further includes at least one limiting structure, and the limiting structure is used to limit at least one position in the length direction of the battery 300.

[0126] The limiting structure accurately limits the specific position of the battery 300 in the length direction through its specific shape, size, and the way it cooperates with the battery 300 and the supporting structure 102 and other related components.

[0127] When the battery 300 is placed on the supporting structure 102 and is ready 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.

[0128] For example, if the limiting structure is in the shape of 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 in the form of a positioning pin, the positioning pin will be inserted into the positioning hole reserved on the outer shell of the battery 300, which also serves to limit the position of the battery 300.

[0129] 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 piece 1015, the second limiting unit 105 includes at least one second limiting piece 1016, and the first limiting unit 104 and the second limiting unit 105 can move relative to each other along the second direction.

[0130] 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 accommodated between two adjacent first guide posts 106, and the second direction is perpendicular to the direction of the locking assembly pointing to the first docking valve.

[0131] A plurality of guide posts 106 are arranged at intervals along the second direction to form a frame-like structure. When the battery 300 is placed on the supporting structure 102, it will be accommodated between two adjacent first guide posts 106. Since the second direction is perpendicular to the direction in which the locking assembly points to the first docking valve, the guide posts 106 mainly play a role in the direction perpendicular to the docking movement direction of the battery 300.

[0132] In some embodiments, a support member 107 is further included. The support member 107 is disposed between the locking assembly and the first docking valve. The support member 107 is suitable for supporting the battery 300 .

[0133] In some embodiments, the present application also includes a transport system, which includes a transport fixture 100 and a docking device 200, and the battery 300 is connected to the docking device 200 through a first docking valve.

[0134] The support member 107 is located between the locking assembly and the first docking valve, and its main function is to provide a stable support platform for the battery 300. It contacts the bottom or side of the battery 300 (depending on the specific support method) through its own structural design, bears the weight of the battery 300, and stably holds the battery 300 at a suitable height and position.

[0135] The shape, size and surface characteristics of the support member 107 are carefully designed according to the appearance characteristics and production process requirements of the battery 300. For example, if the bottom of the battery 300 is flat, the support member 107 may adopt a flat plate structure to provide uniform support over a large area; if the side of the battery 300 needs support, the support member 107 may be designed as an arc structure that matches the curvature of the side of the battery 300 to ensure a close fit, thereby achieving stable support.

[0136] In some embodiments, see Fig.10 The docking device 200 is provided with a fluid pipeline, which is suitable for switching connection between the injection machine and the negative pressure machine.

[0137] The fluid pipeline design in the docking device 200 has the function of switchable connection, which is usually achieved through a special valve, pipe combination or switching mechanism. For example, a three-way valve or a multi-way valve may be used, and different ports of the valve are respectively connected to the injection machine, the negative pressure machine and the related components in the docking device 200 that are connected to the battery 300.

[0138] When liquid injection operation is required, by operating the valve or switching mechanism, the fluid pipeline connects the liquid injection machine with the liquid injection channel corresponding to the battery 300 in the docking device 200, and the electrolyte and other fluids in the liquid injection machine can flow into the battery 300 along the fluid pipeline under pressure.

[0139] When negative pressure operation is required, the fluid pipeline is switched to a state connected to the negative pressure machine by operating the valve or switching mechanism. At this time, the negative pressure machine draws vacuum into the battery 300 through the fluid pipeline to form a negative pressure environment to meet the negative pressure process requirements during the production of the battery 300.

[0140] In some embodiments, the docking device 200 includes a second docking valve, which is suitable for docking with the first docking valve, and the second docking valve is suitable for forming a sealing state to prevent the passage or leakage of fluid.

[0141] The docking of the second docking valve and the first docking valve is achieved based on precise mechanical structure matching. The two are designed with mutually matching interface shapes, sizes and connection methods. When docking, the second docking valve can accurately fit with the first docking valve through the driving action of the push assembly 103 and other related components to form a tight connection.

[0142] Furthermore, the second docking valve is suitable for achieving a high vacuum state with a minimum absolute vacuum of 40 Pa.

[0143] In some embodiments, the present application further includes a floating structure 400 connected to the second docking valve, and the floating structure 400 is suitable for correcting the position of the second docking valve.

[0144] When the second docking valve is docking with the first docking valve, the initial position of the second docking valve may slightly deviate from the ideal docking position due to factors such as equipment vibration, installation error, and battery 300 placement position deviation.

[0145] At this time, the elastic element in the floating structure 400 will undergo elastic deformation due to the action of external force, and the second docking valve will be pushed or pulled to perform fine adjustments in a certain direction through the action of the elastic force; or the slidable and rotatable connecting component allows the second docking valve to move or rotate in a small range in the corresponding degree of freedom, thereby realizing the correction of the position of the second docking valve to make it closer to the ideal docking position.

[0146] In some embodiments, the floating structure includes a fixed block 401, the second docking valve passes through the fixed block, and the fixed block is provided with an accommodating space.

[0147] See also Fig. 9 The floating structure also includes a floating member 402, which is arranged in the accommodating space and is connected to the second docking valve around the circumference of the second docking valve.

[0148] Exemplarily, the floating member 402 is a spring.

[0149] The fixed block, as the basic support part of the floating structure, provides a relatively fixed installation position and frame for the entire floating structure. The second docking valve penetrates the fixed block, so that the fixed block can play a certain positioning and restraining role on the second docking valve, limiting its excessive movement in a direction perpendicular to the penetration direction.

[0150] In some embodiments, see Fig.14 as well as Fig.17 , Fig.18 The docking device 200 is a liquid injection device 218 or a vacuum extraction device 219.

[0151] When the docking device 200 is used as a liquid injection device, its core function is to accurately inject a specific liquid (usually an electrolyte) into the battery 300. It is tightly connected with the docking structure of the battery 300 (such as the first docking valve, the second docking valve, etc.) to ensure that a sealed channel is formed during the liquid injection process to prevent electrolyte leakage.

[0152] The docking device 200 has the dual functions of a liquid injection device or a vacuum pumping device, which greatly improves its applicability in the production process of the battery 300. In different processes of manufacturing the battery 300, it can perform liquid injection operations to accurately inject electrolyte into the battery 300 to lay the foundation for the electrochemical performance of the battery 300; it can also perform vacuum pumping operations to create a suitable negative pressure environment inside the battery 300, which is conducive to the smooth development of subsequent processes (such as formation, etc.).

[0153] In some embodiments, the docking device 200 docking component is composed of a component base 201, a height adjustment component 203 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 thrust cylinder 212, a floating joint 213, a thrust connecting rod 214, a prying cylinder 215, a prying piece 216 and a docking joint assembly 217.

[0154] See also Fig.10 as well as Fig.11 , Fig.14 as well as Fig.16 The functional workstation docking component assembly consists of a component mounting base 201, a height adjustment component 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 thrust cylinder 212, a floating joint 213, a thrust connecting rod 214, a prying cylinder 215, a prying piece 216, and a docking joint assembly 217.

[0155] The sub-mount base 201 is used as a basic component, and the height adjustment component mounting base 202 is installed on the sub-mount base 201 to provide an installation position for the height adjustment component 203. They may be fixed by bolts and other connecting parts to ensure that the position of the height adjustment component mounting base 202 on the sub-mount base 201 is stable.

[0156] The height adjustment component 203 is mounted on the height adjustment component mounting seat 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, and the adjustment method may be achieved by a threaded structure or hydraulic pressure.

[0157] The solenoid valve 205 is mounted on the component mounting plate 204 and fixed by mounting holes and bolts and other connectors to control the on and off of fluids (such as gas and liquid). The adjusting bolt 206 is also mounted on the component mounting plate 204 to further fine-tune parameters such as the position or tension of related components.

[0158] The guide shaft 208 is mounted on the mounting base 210 or other supporting structure through the oil-free bushing 209. The oil-free bushing 209 plays a role in reducing friction and guiding, so that the guide shaft 208 can move linearly smoothly. The mounting base 210 and the mounting base plate 211 cooperate with each other to provide a stable bottom support structure for the entire device.

[0159] The propulsion cylinder 212 is installed on the mounting base plate 211 or other suitable positions, and the piston end of the propulsion cylinder 212 is connected to the propulsion connecting rod 214 through the floating joint 213. The floating joint 213 can compensate for a certain angle deviation to ensure that the propulsion force can be effectively transmitted to the propulsion connecting rod 214. The expelling cylinder 215 is also installed at a suitable position, and its piston end is connected to the expelling piece 216 for performing the expelling action.

[0160] The butt joint assembly 217 is installed at a corresponding position and may be connected to other components that need to be butted. The specific connection method depends on the butt joint requirements and may be a variety of connection methods such as plug-in type and threaded type. The cover plate 207 is installed on the outside of the entire device to protect the internal components and be beautiful. It is connected to other components by bolts or buckles.

[0161] When the height of the component mounting plate 204 needs to be adjusted, the height adjustment assembly 203 is operated. For example, if the height adjustment assembly 203 is threaded, the telescopic part of the height adjustment assembly 203 is extended or contracted by rotating the adjustment bolt, etc., so as to change the height of the component mounting plate 204 to meet different working requirements, such as matching the docking height with other equipment.

[0162] The electromagnetic valve 205 controls the opening and closing of the fluid channel according to the signal of the control system. For example, in an automated production line, when it is necessary to drive the cylinder to move, the electromagnetic valve 205 opens the corresponding air path to allow compressed air to enter the cylinder and push the piston to move.

[0163] After the propulsion cylinder 212 receives the air pressure signal, the piston extends or retracts under the action of the air pressure, and transmits the force through the floating joint 213 and the propulsion connecting rod 214 to realize the function of pushing other components to perform linear motion, such as pushing products or other fixtures to adjust their positions or docking operations.

[0164] When the prying cylinder 215 is working, the piston drives the prying piece 216 to move, and the parts that need to be separated or positioned are pryed apart. For example, in the product assembly process, adjacent parts are pryed apart by a certain distance to facilitate the next assembly operation.

[0165] During the movement of the entire device, the guide shaft 208, under the guidance of the oil-free bushing 209, ensures that the moving parts move linearly along the predetermined direction, prevents deflection, and ensures the accuracy and stability of the movement. For example, when the thrust cylinder 212 pushes the thrust connecting rod 214, the guide shaft 208 provides accurate motion guidance for the relevant parts.

[0166] The docking joint assembly 217, with the cooperation of other components, such as being pushed to a suitable position by the propulsion cylinder 212, is connected to the docking components of other equipment to achieve docking between products or tooling fixtures, and complete functions such as transmission of liquids, gases, signals, etc. or mechanical connection.

[0167] The butt joint assembly 217 is composed of a hydraulic quick joint female head, a joint mounting block, a functional pipeline joint, an assembly mounting block, an assembly fixing block, an assembly connecting block, a spring, a locking nut and a functional pipeline.

[0168] In the system of the present invention, the mobile fixture part can be transported as a whole with the conveyor line, while the docking part of the docking device 200 is fixed in a fixed position for use. When the pipeline of the docking part of the docking device 200 is connected to the injection circuit and the injection pump, it is used as an injection machine; when the pipeline of the docking part of the docking device 200 is connected to the vacuum circuit, it can be used as a negative pressure machine.

[0169] When the battery 300 is placed in the fixture, it is in position one, the locking part is installed with the closing clamp, and the liquid injection hole of the battery 300 is pressed against the pressure-maintaining joint assembly, so that the battery 300 is in position two to complete the clamping, positioning and sealing of the battery 300; when the processing of the battery 300 is completed, the locking part is installed with the opening clamp, the battery 300 loses its restraint force and can be easily taken out.

[0170] The principle of the switch clamp installed in the locking part: when closing the clamp, push the locking plate, then the push block contacts the battery 300, continue to push the locking plate, and then the locking plate contacts.

[0171] Continue to push the wedge block of the automatic lock buckle 1035 to rotate clockwise. Until the locking plate push plane coincides with the hook surface of the automatic lock buckle 1035, the wedge block of the automatic lock buckle 1035 returns counterclockwise under the action of the spring, and the automatic lock buckle 1035 is locked with the locking plate, completing the installation and closing of the locking part.

[0172] When opening the clamp, the wedge block of the clamp opening device is pushed horizontally until it contacts the wedge block of the automatic lock 1035, and the wedge block of the automatic lock 1035 is further pushed to rotate clockwise until the hook surface of the wedge block of the automatic lock 1035 is separated from the contact surface of the locking plate. At this time, the tension spring drives the guide rod to retract, and the locking plate pops up and resets, completing the installation and opening of the locking part.

[0173] The docking process is divided into the following steps:

[0174] Initial state adjustment, when the mobile fixture is in place and positioned, the cylinder retracts, driving the push-off piece 216 to retract. When the push-off piece 216 contacts the female head of the hydraulic quick connector, its annular structure drives the outer ring of the female head of the hydraulic quick connector to retract. At this time, the female head is in a loose state.

[0175] During the docking process, the cylinder is pushed out, driving the docking joint assembly 217 to extend forward. Until the docking pressure-maintaining joint assembly and the hydraulic quick joint are docked, the connection between the battery 300 and the functional pipeline is completed.

[0176] In the locked state, the cylinder extends, driving the push-out piece 216 to extend, the male and female heads of the hydraulic quick connector interlock, and the entire structure is locked. Due to the performance of the hydraulic quick connector, it can be considered to be completely sealed and leak-free before and after docking, completing the pressure-maintaining sealed quick docking.

[0177] During the separation process, when the functional process (liquid injection, negative pressure) is completed, the cylinder retracts, driving the push-off piece 216 to retract. When the push-off piece 216 contacts the female head of the hydraulic quick connector, its annular structure drives the outer ring of the female head of the hydraulic quick connector to retract. At this time, the female head is in a loosened state. Subsequently, the cylinder retracts, driving the docking joint assembly 217 to retract backward, leaving the pressure-maintaining joint assembly, and quickly disengaging from the docking. After the docking is released, the interlocking sealing joint is instantly reset and closed when the pressure is increased to prevent air from entering, and has sufficient automatic sealing capability. The equipment is then reset and the next docking can be carried out.

[0178] Specific combination Figure 1 as well as Fig.10 The battery 300 is clamped and fixed as shown in the figure: when the battery 300 is placed in the fixture, it is in position one, the locking part is installed to close the clamp, the liquid injection hole of the battery 300 is pressed against the pressure-maintaining joint assembly, so that the battery 300 is in position two to complete the clamping, positioning and sealing of the battery 300; when the processing of the battery 300 is completed, the locking part is installed to open the clamp, the battery 300 loses its restraint and can be easily taken out.

[0179] When closing the clamp, push the locking plate, then the push block contacts the battery 300, continue to push the locking plate, then the locking plate contacts the automatic lock buckle 1035, continue to push to make the wedge block of the automatic lock buckle 1035 rotate clockwise, until the locking plate pushing plane coincides with the hook surface of the automatic lock buckle 1035, the wedge block of the automatic lock buckle 1035 returns counterclockwise under the action of the spring, at this time the automatic lock buckle 1035 is locked with the locking plate, completing the closing of the locking part.

[0180] When opening the clamp, the wedge of the clamp opening device is inserted, and the wedge block of the clamp opening device is pushed horizontally until it contacts the wedge block of the automatic lock buckle 1035, and the wedge block of the automatic lock buckle 1035 is further pushed to rotate clockwise until the hook surface of the wedge block of the automatic lock buckle 1035 is separated from the contact surface of the locking plate. At this time, the tension spring drives the guide rod to retract, and the locking plate pops up and resets, completing the clamping of the locking part.

[0181] Battery 300 pressure maintenance: When the battery 300 is placed in the fixture and the locking part is installed to close the clamp to complete the clamping of the battery 300, the injection hole of the battery 300 will press against the needle sealing pad and maintain sufficient pre-tightening force to deform the sealing pad, thereby achieving the effect of sealing with the outside world. At this time, the inside of the battery 300 is only connected to the injection needle.

[0182] Therefore, the present invention does not require the removal of the fixture during the process of liquid injection, negative pressure, negative pressure static, and high temperature infiltration, and has the following characteristics:

[0183] Battery 300 is closed and pressurized throughout the whole process: Battery 300 is closed and pressurized throughout the loading process. After the battery cell is fixed in the fixture, it is always in a closed and sealed state during the transportation process and process actions (liquid injection, negative pressure, formation). After the battery 300 has extracted a sufficient vacuum degree, the negative pressure static process can be directly started without setting up a negative pressure chamber to extract negative pressure, simplifying the equipment plan and optimizing the cycle time. In addition, the fully closed method can keep the battery 300 in a negative pressure formation state during the transportation process after the negative pressure is applied, saving cycle time, omitting process nails, simplifying the plan, optimizing costs, and making the process performance of different batches of battery cells more uniform.

[0184] Quick docking and sealing: During liquid injection or negative pressure, the connector on the fixture can be quickly docked with the docking device 200 to complete the circuit. Positioning is convenient. After the docking is released, the interlocking sealing connector can be instantly reset and closed when the pressure is increased to prevent air from entering. It has sufficient automatic sealing ability, saves equipment and time, and is a cup-free liquid injection method. The same effect of cup liquid injection can be achieved without a positive pressure pipeline.

[0185] Adapt to high temperature formation: The fixture can be carried into the high temperature formation room, 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. While the operation is convenient and the beat is saved, the processed battery 300 has better process performance.

[0186] After the battery cell is installed, when the vacuum is drawn, the fixture can achieve a high vacuum state pressure maintenance effect with a minimum absolute vacuum of 40pa.

[0187] The mobile fixture can be moved and transported. The overall structure of the mobile fixture is relatively light, and the frame structure forms a plane with a large enough area, which is convenient for transportation through 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 can replace the mechanism to bear wear and are convenient for disassembly and replacement.

[0188] The present application also has the following advantages in terms of compatibility with different battery 300 sizes:

[0189] (1) Adjustable clamp: The limiter may have an adjustable structure. For example, through the connection between the moving member and the limiter, the moving member can drive the limiter to move within a certain range, thereby adapting to batteries 300 of different lengths.

[0190] The limiter itself may have an adjustable clamping portion, which can be adjusted according to the width or thickness of the battery 300 to ensure that a suitable clamping force and fixing effect can be provided for batteries 300 of different sizes.

[0191] (2) Compatibility design of the frame. The frame may have sufficient space and universal design. Its internal structure can accommodate batteries 300 of different sizes, and the layout takes into account the adaptation of different sizes of batteries 300. For example, the frame may be provided with adjustable positioning structures, such as guide pillars and compatible adjustment plates, etc. By adjusting the positions of these structures, it can adapt to batteries 300 of different diameters or shapes.

[0192] (3) In terms of the convenience of docking with the docking device 200, the clamp may be equipped with a quick docking connector. These connectors are specially designed, such as hydraulic quick connectors, to achieve quick plug-in and pull-out connection with the docking device 200. When the clamp is transported to the vicinity of the docking device 200, the connector can be quickly docked with the corresponding pipeline or equipment, reducing the docking time.

[0193] (4) Butt joints may have automatic alignment and locking functions. For example, during the butt joint process, the joint can automatically adjust its position to ensure accurate connection, and can automatically lock after connection to prevent accidental detachment, thereby improving the convenience and reliability of the butt joint.

[0194] (5) Standardized valves

[0195] The valve of the fixture may adopt a standardized design. Whether it is docking with a liquid injection device, a vacuum device or other docking devices 200, a unified standard is followed, which can avoid docking difficulties caused by interface mismatches and improve the versatility and docking convenience of the fixture between different workstations.

[0196] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
