[0001] Cross-referencing

[0002] This application incorporates Chinese Patent Application No. 2024213453117, filed on June 13, 2024, entitled “Machine docking structure and battery production line”, which is incorporated herein by reference in its entirety. Technical Field

[0003] This application relates to the field of battery technology, and in particular to a machine docking structure and a battery production line. Background Technology

[0004] With the development of new energy technologies, batteries are being used more and more widely, for example in mobile phones, laptops, electric vehicles, electric cars, electric airplanes, electric ships, electric toy cars, electric toy ships, electric toy airplanes, and power tools.

[0005] In the battery production process, multiple pieces of equipment are often required. Different pieces of equipment need to be connected by a machine docking structure to prevent the working medium inside the equipment from leaking out. However, once the current machine docking structure is installed, its sealing performance is often difficult to test.

[0006] Summary of the Invention

[0007] A first aspect of this application provides a machine docking structure, including: a pipeline and at least one set of mounting components, the mounting components including a first flange, a second flange, an air pump, and a sensor; the first flange is connected to the pipeline, and the second flange is connected to an external device; the first flange and the second flange are inserted into each other; a detection cavity is formed between the sections where the first flange and the second flange are inserted; at least one of the first flange and the second flange has two detection holes, each detection hole communicating with the detection cavity; one detection hole is connected to the air pump; the other detection hole is connected to the sensor. The pressure inside the detection cavity is adjusted by the air pump to be different from the pressure inside or outside the pipeline. When a seal failure occurs between the detection chamber and the pipeline, the pressure difference between the detection chamber and the inside or outside of the pipeline can create a flow guide between the inside or outside of the pipeline and the detection chamber, preventing cross-contamination of substances between the inside and outside of the pipeline. Furthermore, while preventing cross-contamination of substances between the inside and outside of the pipeline, monitoring pressure or flow changes in the detection chamber via sensors allows for monitoring of the connection status between the first and second flanges. This facilitates real-time monitoring between the detection chamber and the pipeline, preventing leakage of the working medium and ensuring the safety of the operator's working environment.

[0008] In one embodiment, the first flange is movably fitted onto the outer circumferential surface of the second flange along the length of the pipeline; two detection holes are provided on the second flange and penetrate the sidewall of the second flange to communicate with the detection chamber. This prevents the working medium inside the pipeline from leaking from the area where the second flange and the first flange are inserted, ensuring safety.

[0009] In one embodiment, the mounting assembly includes two sets of sealing rings, which are spaced apart along the length of the pipe on the outer circumferential surface of the second flange. The outer circumferential surface of the second flange, the inner circumferential surface of the first flange, and the two sets of sealing rings together form the detection chamber. The two sets of sealing rings achieve a better sealing effect, thereby preventing leakage of the working medium inside the pipe from the area where the second flange and the first flange intersect. The detection hole can penetrate radially through the sidewall of the second flange and form an opening on the outer circumferential surface of the second flange in the area between the two sets of sealing rings; thus, the detection hole connects to the detection chamber, thereby enabling the sealing monitoring function.

[0010] In one embodiment, two annular positioning grooves are formed on the outer circumferential surface of the second flange; two sets of sealing rings are respectively fitted into the two positioning grooves. By arranging the two sets of sealing rings at intervals along the length of the pipe on the outer circumferential surface of the second flange, and fixing them in the length direction through one positioning groove for each set, separation of the sealing rings from the second flange is avoided.

[0011] In one embodiment, the mounting assembly includes two air nozzles, each inserted into an opening in one of the two detection holes facing the inside of the pipe; one detection hole is connected to the air pump via the air nozzle; the other detection hole is connected to the sensor via the air nozzle. Thus, by connecting the air pump and sensor to the detection holes via air nozzles, a seal monitoring function can be achieved.

[0012] In one embodiment, the sensor is a pressure sensor or a flow rate sensor.

[0013] In one embodiment, the machine docking structure includes two connectors, which are respectively disposed at the pipe openings at opposite ends of the pipe; the first flange is detachably connected to the connectors.

[0014] In one embodiment, the connector is integrally folded outward from the pipe opening to form a connecting flange; the connector has multiple fixing holes. This facilitates the connection and fixing of the connector to the first flange.

[0015] In one embodiment, each connector is provided with multiple fixing holes, at least some of which are strip-shaped holes. Projected along the length of the pipe, the extension direction of the fixing hole on one connector intersects the extension direction of the fixing hole on the other connector. By placing two connectors at the pipe openings at opposite ends of the pipe, each connector is provided with multiple fixing holes. The fixing holes are strip-shaped, allowing for a certain degree of positional adjustment along the extension direction of the fixing holes when bolted to an external structure. Furthermore, projected along the length of the pipe, the extension direction of the fixing hole on one connector intersects the extension direction of the fixing hole on the other connector. Further, the extension directions of the fixing holes on one connector are different from those on the other connector, thereby allowing adjustment of the pipe position in both directions. This facilitates simultaneous docking of production equipment at both ends without bending or tilting the pipe, ultimately simplifying the structure of the machine docking structure and making installation easier.

[0016] In one embodiment, the extending direction of the fixing hole on one of the connectors is parallel to the width direction of the pipe; and / or, the extending direction of the fixing hole on the other connector is parallel to the height direction of the pipe. Thus, the fixing holes on the two connectors can be adjusted along the width and height directions of the pipe to change their bolt connection positions with the external structure, thereby allowing for pipe position adjustment in both directions. This ensures that the pipe can be aligned with the production equipment at both ends without bending or tilting, guaranteeing convenient installation and a simple structure.

[0017] In one embodiment, the mounting assembly includes a first gasket disposed between the first flange and the connector. Thus, the first gasket sandwiched between the first flange and the connector provides better sealing performance, preventing leakage of the working medium inside the pipeline from the area where the first flange and the connector meet, ensuring safety.

[0018] In one embodiment, the mounting assembly includes a mounting plate and a second bolt. The end of the second flange furthest from the first flange is disposed opposite the mounting plate. The second bolt passes through the mounting plate and connects to the second flange. Thus, the mounting plate and the second flange are respectively clamped on both sides of the connecting wall of the production equipment to be connected. The second bolt passes sequentially through the mounting plate, the connecting wall of the production equipment, and the bolt hole on the second flange, thereby fixing the production equipment to one end of the second flange.

[0019] In one embodiment, the mounting assembly includes a second gasket disposed between the second flange and the mounting plate. Thus, the second gasket, positioned between the second flange and the mounting plate and closely fitted to the connection wall of the production equipment, provides better sealing performance, preventing leakage of the working medium inside the production equipment from the area where the second flange connects to the production equipment, thereby ensuring safety.

[0020] In one embodiment, the machine docking structure includes a viewing window disposed on the pipe wall. By placing the viewing window on the pipe wall, operators can easily observe the flow of the working medium inside the pipe and the installation status inside the pipe, facilitating the installation of production equipment at both ends.

[0021] A second aspect of this application provides a battery production line, including the aforementioned machine docking structure.

[0042] Currently, judging from market trends, the application of power batteries is becoming increasingly widespread. Power batteries are not only used in energy storage systems such as hydropower, thermal power, wind power, and solar power plants, but also widely applied in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in aerospace and other fields. With the continuous expansion of power battery applications, market demand is also constantly increasing.

[0043] In battery manufacturing, multiple pieces of equipment are assembled and connected to form a battery production line for large-scale battery production. Different production equipment needs to be connected using a machine docking structure to prevent leakage of the working medium inside the equipment. However, since the length, height, and width of different pieces of equipment are often different, and the positions of the connection ports on the equipment also vary, the machine docking structure needs to be repeatedly adjusted in terms of left-right width and up-down height between the two pieces of equipment. After installation, if gaps appear at the connection, or if the sealing structure of the machine docking structure itself ages and wears down, resulting in sealing performance problems, it will be impossible to directly detect leakage, leading to unclear leakage of the working medium of the production equipment.

[0044] To alleviate the inconvenience of testing the sealing performance of the machine tool docking structure, a first flange, a second flange, an air pump, and a sensor can be incorporated into the design of the machine tool docking structure. A testing chamber is formed between the sections where the first flange and the second flange are inserted. The pressure inside the testing chamber is adjusted by the air pump, and the testing chamber is tested by the sensor. This allows for convenient real-time monitoring of the connection between the testing chamber and the pipeline, preventing sealing failure.

[0045] This application provides a machine docking structure, which can be, but is not limited to, connecting battery production equipment. The battery production equipment can be an unpacking machine, welding machine, dispensing machine, packaging machine, or other equipment that may be used on a battery production line.

[0047] The first aspect of this application provides a machine docking structure, including: a pipe 10 and at least one set of mounting components 40.

[0048] Each mounting assembly 40 includes a first flange 41, a second flange 42, an air pump (not shown), and a sensor (not shown). The first flange 41 is connected to the pipe 10, and the second flange 42 is connected to an external device; the first flange 41 and the second flange 42 are inserted into each other; a detection cavity 47 is formed between the sections where the first flange 41 and the second flange 42 are inserted; at least one of the first flange 41 and the second flange 42 has two detection holes 46, each detection hole 46 communicating with the detection cavity 47; one detection hole 46 is connected to the air pump; the other detection hole 46 is connected to the sensor.

[0049] The pipe 10 is a thin-walled, hollow tube that serves as a connection channel between the two battery production devices. The pipe 10 can be square or round; that is, its cross-section, projected along its length (X), is square or circular. Furthermore, the cross-section of the pipe 10 can be elliptical, triangular, rhomboid, or other polygonal shapes depending on the design requirements. The pipe 10 is typically made of sheet metal, which is low-cost and uses mature technology. It can also be made of plastic, alloy tubing, etc., depending on the design; this application does not limit this specific choice.

[0050] Mounting assembly 40 is used to connect pipe 10 to external production equipment. Normally, mounting assembly 40 only serves a connecting function. However, depending on design requirements, mounting assembly 40 can adjust its length along the length direction X of pipe 10; thus, the installation distance of the machine docking structure in the length direction X of pipe 10 can be adjusted, facilitating simultaneous docking with production equipment.

[0051] Specifically, each mounting assembly 40 includes a first flange 41, a second flange 42, an air pump (not shown), and a sensor (not shown). The first flange 41 is connected to one end of the pipe 10, and the other end of the second flange 42, away from the first flange 41, is connected to an external device.

[0052] The first flange 41 and the second flange 42 are inserted into each other to achieve docking. By adjusting the insertion depth of the first flange 41 and the second flange 42, the length of the mounting component 40 along the length direction X of the pipeline 10 can be effectively adjusted. In this way, the installation distance of the machine docking structure along the length direction X of the pipeline 10 can be adjusted, which facilitates the simultaneous docking of production equipment. This not only simplifies the structure of the machine docking structure, but also makes installation more convenient.

[0053] A detection cavity 47 is formed between the section where the first flange 41 and the second flange 42 are inserted. The detection cavity 47 is a closed annular cavity, and is distributed circumferentially around the periphery of the pipe 10 with the length direction X of the pipe 10 as the axis of rotation.

[0054] Different production equipment are connected using a machine docking structure. To prevent leakage of the working medium inside the production equipment, the machine docking structure can initiate a sealing test simultaneously with the connection. At least one of the first flange 41 and the second flange 42 has two detection holes 46, each of which is connected to a detection chamber 47. One detection hole 46 is connected to an air pump, and the other detection hole 46 is connected to a sensor, thus facilitating detection.

[0055] In this way, the pressure inside the detection chamber 47 can be adjusted by an air pump to be different from the pressure inside or outside the pipe 10. When a seal failure occurs between the detection chamber 47 and the pipe 10, the pressure difference between the detection chamber 47 and the inside or outside of the pipe 10 can create a flow guide between the inside or outside of the pipe 10 and the detection chamber 47, preventing cross-contamination of substances inside and outside the pipe 10. In addition, while preventing cross-contamination of substances inside and outside the pipe 10, the connection status of the first flange 41 and the second flange 42 can be monitored by the sensor monitoring the pressure or flow changes in the detection chamber 47. This facilitates real-time monitoring between the detection chamber and the pipe, preventing leakage of the working medium and ensuring the safety of the operator's working environment.

[0056] In some embodiments, both the first flange 41 and the second flange 42 can be formed from rigid plastics; for example, polyoxymethylene resin can be used, which has the advantages of being lightweight, corrosion-resistant, and low-cost. Alternatively, both the first flange 41 and the second flange 42 can be formed from metals such as aluminum alloy or stainless steel alloy, resulting in high structural strength, good connection strength, and convenient processing.

[0057] In some embodiments, the sensor is a pressure sensor or a flow rate sensor; it can be used to monitor pressure changes or flow rate changes in the detection chamber 47, thereby enabling monitoring of the connection status between the first flange 41 and the second flange 42, preventing leakage of the working medium, and ensuring the safety of the operator's working environment.

[0058] In some possible embodiments, the first flange 41 is movably sleeved on the outer peripheral surface of the second flange 42 along the length direction X of the pipe 10; two detection holes 46 are provided on the second flange 42 and penetrate through the side wall of the second flange 42 to communicate with the detection cavity 47.

[0059] Referring to Figures 1 to 7, both the first flange 41 and the second flange 42 are flange ring structures with a hollow center. Depending on whether the cross-section of the pipe 10 is square or circular, the first flange 41 and the second flange 42 can be square rings or circles, depending on the design. This application embodiment does not limit this.

[0060] It is understandable that the plane where the connection surfaces of the first flange 41 and the second flange 42 are located is perpendicular to the length direction X of the pipe 10; the first flange 41 and the second flange 42 have a certain thickness in the length direction X of the pipe 10, so that they fit together.

[0061] The inner diameter of the first flange 41 is slightly larger than the outer diameter of the second flange 42. The first flange 41 is movably fitted onto the outer circumferential surface of the second flange 42 along the length X of the pipe 10. Two inspection holes 46 are provided on the second flange 42 and penetrate through the side wall of the second flange 42 to connect to the inspection cavity 47. The area where the first flange 41 and the second flange 42 are inserted can usually be sealed with a sealing ring to prevent the working medium inside the pipe 10 from leaking from the area where the second flange 42 and the first flange 41 are inserted, thus ensuring safety.

[0062] In other embodiments, the two detection holes 46 may also be provided on the first flange 41 and penetrate the side wall of the first flange 41 to connect the detection cavity 47; the specific connection structure is similar to that of the detection holes 46 being provided on the second flange 42, and will not be described in detail here. For ease of understanding, the following embodiments will be described with the detection holes 46 being provided on the second flange 42.

[0063] In some possible embodiments, referring to Figures 1 to 7, the mounting assembly 40 includes two sets of sealing rings 45, which are spaced apart along the length X of the pipe 10 on the outer circumferential surface of the second flange 42. The outer circumferential surface of the second flange 42, the inner circumferential surface of the first flange 41, and the two sets of sealing rings 45 together form a detection cavity 47.

[0064] The inner diameter of the first flange 41 is slightly larger than the outer diameter of the second flange 42. The first flange 41 is movably fitted onto the outer circumferential surface of the second flange 42 along the length X of the pipe 10. Two sets of sealing rings 45 are arranged at intervals along the length X of the pipe 10 on the outer circumferential surface of the second flange 42. When the first flange 41 and the second flange 42 are inserted and mated, the sealing rings 45 are positioned between the second flange 42 and the first flange 41, thereby sealing the gap at the insertion point of the first flange 41 and the second flange 42. The two sets of sealing rings 45 can achieve a better sealing effect, thereby preventing the working medium inside the pipe 10 from leaking from the area where the second flange 42 and the first flange 41 are inserted, ensuring safety.

[0065] The detection cavity 47 is formed by the outer peripheral surface of the second flange 42, the inner peripheral surface of the first flange 41, and the two sets of sealing rings 45. The detection cavity 47 is a closed annular cavity, and is distributed circumferentially around the periphery of the pipe 10 with the length direction X of the pipe 10 as the axis of rotation. The detection hole 46 can penetrate the side wall of the second flange 42 radially and form an opening in the area between the two sets of sealing rings 45 on the outer peripheral surface of the second flange 42. Thus, the detection hole 46 connects to the detection cavity 47.

[0066] During seal monitoring, the pressure inside the detection chamber 47 can be adjusted by an air pump to be different from the pressure inside or outside the pipe 10. When one set of sealing rings 45 fails to seal, the pressure difference between the detection chamber 47 and the inside or outside of the pipe 10 allows for flow guidance between the inside or outside of the pipe 10 and the detection chamber 47, preventing cross-contamination between the substances inside and outside the pipe 10. Furthermore, while preventing cross-contamination between the substances inside and outside the pipe 10, monitoring pressure or flow changes in the detection chamber 47 via a sensor allows for monitoring of the connection status between the first flange 41 and the second flange 42. This enables safe replacement of the first flange 41 and the second flange 42, preventing leakage of the working medium. If leakage occurs, a temporary airtight seal can be activated using another sealing ring 45 to ensure a seal, thus ensuring the safety of the operator's working environment.

[0067] Optionally, the sealing ring 45 can be an O-ring or a square ring structure; the sealing ring 45 is disposed between the second flange 42 and the first flange 41, and is usually made of rubber, which has good sealing performance.

[0068] In some possible embodiments, as shown in Figures 1 to 7, two annular positioning grooves (not shown) are formed on the outer peripheral surface of the second flange 42; two sets of sealing rings 45 are respectively fitted into the two positioning grooves.

[0069] The number of positioning grooves corresponds to the number of sealing rings 45; the two sets of sealing rings 45 are arranged at intervals along the length direction X of the pipe 10 on the outer circumferential surface of the second flange 42, and can be fixed in the length direction X by one positioning groove for each, so as to avoid the sealing rings 45 from separating from the second flange 42.

[0070] In some embodiments, as shown in Figures 1 to 7, the mounting assembly 40 includes two air nozzles 70, which are respectively inserted into the openings of two detection holes 46 facing the inside of the pipe 10.

[0071] Two air seal nozzles 70 are respectively inserted into one detection hole 46 and protrude from the inner circumferential surface of the second flange 42; one detection hole 46 is connected to the air pump through the air nozzle 70; the other detection hole 46 is connected to the sensor through the air nozzle 70.

[0072] Mounting assembly 40 may also include two pressure reducing valves (not shown). During installation, the air nozzle 70 on one of the detection ports 46 is connected to an air pump through a pressure reducing valve to fill the detection chamber 47 with a working medium at an appropriate pressure. The other detection port 46 is connected to a sensor through a pressure reducing valve. The sensor can be a pressure sensor or a flow rate sensor, which can be used to monitor the pressure or flow rate of the working medium in the detection chamber 47 in real time, thereby completing the seal monitoring function.

[0073] In some embodiments, as shown in Figures 1 to 7, the detection hole 46 is a stepped hole, which facilitates the insertion and positioning of the air nozzle 70 into the detection hole 46.

[0074] In some possible embodiments, referring to Figures 1 to 7, the machine docking structure includes two connectors 20, which are respectively disposed at the pipe openings at opposite ends of the pipe 10; the first flange 41 is detachably connected to the connectors 20.

[0075] The connector 20 is used to connect the pipe 10 and the mounting assembly 40. It can be a plate structure or a block structure. The connector 20 can be integrally connected with the pipe 10, or it can be processed separately from the pipe 10 and fixed together by welding, bolting or other methods.

[0076] In related technologies, battery manufacturers often assemble and connect multiple pieces of equipment to form a battery production line for large-scale battery production. Different production equipment needs to be connected using a machine docking structure to prevent leakage of the working medium inside the equipment. However, due to the different lengths, heights, and widths of various pieces of equipment, as well as the different positions of the connection ports on the equipment, the machine docking structure needs to be repeatedly adjusted in terms of left-right width and up-down height between two pieces of equipment, resulting in a complex structure and inconvenient installation.

[0077] To alleviate the problems of complex structure and inconvenient installation of machine docking structures, strip holes extending in different directions can be designed at both ends of the machine docking structure. This allows for adjustment of the pipe position in both directions, facilitating simultaneous docking of production equipment at both ends without requiring the pipe to be bent or tilted. Ultimately, this simplifies the structure of the machine docking structure and makes installation easier.

[0078] In some possible embodiments, as shown in Figures 1 to 7, each connector 20 is provided with a plurality of fixing holes 30. At least some of the fixing holes 30 are strip-shaped holes. Projected along the length X direction of the pipe 10, the extending direction of the fixing hole 30 on one connector 20 intersects the extending direction of the fixing hole 30 on another connector 20.

[0079] By setting two connectors 20 at the pipe openings at opposite ends of the pipe 10, each connector 20 is provided with multiple fixing holes 30. By setting the fixing holes 30 to be strip-shaped, their position can be adjusted to a certain extent along their extension direction when bolted to an external structure. Furthermore, projecting along the length X-direction of the pipe 10, the extension direction of the fixing holes 30 on one connector 20 intersects with that on the other connector 20. This further ensures that the extension directions of the fixing holes 30 on one connector 20 and the other connector 20 are different, allowing adjustment of the pipe 10's position in both directions. This facilitates simultaneous connection of production equipment at both ends without bending or tilting the pipe 10, ultimately simplifying the machine docking structure and making installation easier.

[0080] A fixing hole 30 on one of the connectors 20 extends along a first direction; a fixing hole 30 on the other connector 20 extends along a second direction; the first direction and the second direction are intersected and projected onto the same plane along the length direction X of the pipe 10.

[0081] Typically, the first direction can be set to be parallel to the width direction Y of the pipe 10, and the second direction can be set to be intersecting the width direction Y. This allows the position of the pipe 10 to be adjusted in both directions, making it convenient to connect the production equipment at both ends simultaneously without bending or tilting the pipe 10. Ultimately, this simplifies the structure of the machine docking structure and makes installation easier.

[0082] Alternatively, the second direction can be set to be parallel to the height direction Z of the pipe 10, and the first direction can be set to be intersecting the height direction Z; thus, the position of the pipe 10 can be adjusted in both directions, which facilitates simultaneous connection of production equipment at both ends without bending or tilting the pipe 10, ultimately making the machine docking structure simpler and easier to install.

[0083] In some possible embodiments, referring to Figures 5 to 7, the extending direction of the fixing hole 30 on one connector 20 is parallel to the width direction Y of the pipe 10; the extending direction of the fixing hole 30 on the other connector 20 is parallel to the height direction Z of the pipe 10. Thus, the fixing holes 30 on the two connectors 20 can be adjusted along the width direction Y and the height direction Z of the pipe 10 to change their bolt connection positions with the external structure. This allows for adjustment of the position of the pipe 10 in both the width and height directions Z, enabling alignment with the production equipment at both ends of the pipe 10 without bending or tilting, ensuring convenient installation and a simple structure.

[0084] It is understandable that the length direction X, the width direction Y, and the height direction Z of the pipe 10 are set perpendicular to each other.

[0085] In some possible embodiments, as shown in Figures 5 to 7, multiple fixing holes 30 on the same connector 20 are distributed around the pipe body of the pipe 10, with adjacent fixing holes 30 spaced apart.

[0086] Specifically, multiple fixing holes 30 on the same connector 20 extend in the same direction. Furthermore, the connector 20 is a ring structure and is located at the edge of the pipe opening of the pipe 10. Multiple fixing holes 30 on the same connector 20 are distributed around the pipe body of the pipe 10. When the connector 20 is connected to an external structure, it can be effectively connected through the fixing holes 30 distributed around the pipe body of the pipe 10, ensuring the connection strength.

[0087] The connection between the first flange 41 and the connector 20 can be either welded or bolted.

[0088] In some possible embodiments, referring to Figures 1 to 7, the connector 20 is integrally folded outward from the pipe opening of the pipe 10 to form a connecting flange; a plurality of fixing holes 30 are formed on the connector 20. All fixing holes 30 penetrate the first connecting flange along the length X of the pipe 10.

[0089] The connector 20 is integrally connected to the pipe 10. Specifically, the pipe 10 can be a sheet metal part; the connector 20 is integrally folded outward from the pipe opening of the pipe 10 into a flat plate shape, and finally surrounds the pipe opening of the pipe 10 to form a connecting flange; the fixing hole 30 penetrates the connecting flange along the length X of the pipe 10, so as to facilitate bolt connection with the first flange 41.

[0090] The connector 20 is a ring structure and is located at the edge of the pipe opening of the pipe 10. Multiple fixing holes 30 on the same connector 20 are distributed around the pipe body of the pipe 10. The first flange 41 is connected to the pipe opening of the pipe 10 through the connector 20. The connection can be effectively achieved through the fixing holes 30 distributed around the pipe body of the pipe 10, ensuring the connection strength.

[0091] In some possible embodiments, the mounting assembly 40 includes a plurality of first bolts; each connector 20 is provided with a plurality of fixing holes 30; the plurality of fixing holes 30 on the connector 20 all extend in the same direction, and the first flange 41 is provided with a plurality of first through holes 43, the first bolts passing through the first through holes 43 and the fixing holes 30 corresponding to the first through holes 43; thereby fixing the first flange 41 to the connector 20.

[0092] In some embodiments, the number of mounting components 40 may be one; referring to Figure 3, the machine docking structure includes a mounting component 40, a mounting plate 60 and a third bolt; the first flange 41 of the mounting component 40 is bolted to one of the connectors 20; the other connector 20 is bolted to the mounting plate 60.

[0093] Specifically, the mounting plate 60 is set at the pipe opening at one end of the pipe 10, and the connector 20 connected to the pipe opening at that end is clamped on both sides of the connecting wall of the production equipment to be connected. The third bolt passes through the mounting plate 60, the connecting wall of the production equipment, and the fixing hole 30 on the connector 20 in sequence, so that the production equipment is fixedly connected to one end of the pipe 10.

[0094] The mounting component 40 is installed on the pipe opening at the other end of the pipe 10. The first flange 41 of the mounting component 40 is bolted to the connector 20 through the fixing hole 30. This facilitates the connection of the second flange 42 of the mounting component 40 to the connecting wall of the production equipment. Then, the first flange 41 and the second flange 42 are inserted to achieve the connection. This not only provides good sealing performance but also simplifies the structure of the machine docking structure and makes installation more convenient.

[0095] Unlike the previous embodiment, in some other embodiments, the machine docking structure may include two mounting components 40; the first flanges 41 of the two mounting components 40 are respectively bolted to two connectors 20, and other structural connections are similar and will not be described in detail here.

[0096] In some possible embodiments, as shown in Figures 1 to 7, the mounting assembly 40 includes a first sealing gasket 44 disposed between the first flange 41 and the connector 20.

[0097] The first sealing gasket 44 has a hollowed-out sheet structure, and its overall shape is similar to or the same as that of the connector 20. The first sealing gasket 44 can be made of materials such as rubber, and has good sealing performance and cushioning performance.

[0098] Specifically, the first sealing gasket 44 has a through hole (not shown). The first bolt is sequentially inserted into the first through hole 43, the through hole on the first sealing gasket 44, and the fixing hole 30 corresponding to the first through hole 43. In this way, the first flange 41 and the connector 20 are connected as a whole. The first sealing gasket 44 is sandwiched between the first flange 41 and the connector 20 to provide better sealing performance, prevent the working medium inside the pipeline 10 from leaking from the area where the first flange 41 and the connector 20 are connected, and ensure safety.

[0099] In some possible embodiments, as shown in Figures 1 to 7, the mounting assembly 40 includes a fixing plate 48 and a second bolt. The end of the second flange 42 away from the first flange 41 is disposed opposite to the fixing plate 48, and the second bolt passes through the fixing plate 48 and is connected to the second flange 42.

[0100] Specifically, the end of the second flange 42 away from the first flange 41 is positioned opposite the fixed plate 48. The fixed plate 48 and the second flange 42 are respectively clamped on both sides of the connecting wall of the production equipment to be connected. The second bolt passes through the mounting plate 60, the connecting wall of the production equipment, and the bolt hole on the second flange 42 in sequence, so that the production equipment is fixedly connected to one end of the second flange 42.

[0101] Optionally, the fixed plate 48 can be formed by processing metals such as aluminum alloy and stainless steel alloy, which has high structural strength, good connection strength and is easy to process.

[0102] In some possible embodiments, as shown in Figures 1 to 7, the mounting assembly 40 includes a second sealing gasket 49 disposed between the second flange 42 and the mounting plate 48.

[0103] The second sealing gasket 49 has a hollowed-out sheet structure, and its overall shape is similar to or the same as that of the second flange 42. The second sealing gasket 49 can be made of materials such as rubber, and has good sealing performance and cushioning performance.

[0104] Specifically, the second gasket 49 has a through hole (not shown), and the second bolt passes sequentially through the mounting plate 60, the through hole on the second gasket 49, the connecting wall of the production equipment, and the bolt hole on the second flange 42, so that the production equipment is fixedly connected to one end of the second flange 42; the second flange 42 and the production equipment are connected as a whole, and the second gasket 49 is placed between the second flange 42 and the fixing plate 48 and is tightly attached to the connecting wall of the production equipment, thereby providing better sealing performance and preventing the working medium inside the production equipment from leaking from the area where the second flange 42 is connected to the production equipment, thus ensuring safety.

[0105] A second aspect of this application provides a battery production line, comprising the aforementioned machine docking structure. The battery production line comprises multiple production equipment assembled and connected to form a single unit, enabling large-scale battery production; for example, unpacking machines, welding machines, dispensing machines, and packaging machines. The machine docking structure connects different production equipment, thereby enabling series or parallel connection of the various production equipment and preventing leakage of the working medium within the production equipment.

[0106] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
