Description

Technical Field

[0001] The present application belongs to the field of battery formation technology, and specifically relates to the field of docking accessories for formation equipment, and thus proposes a formation system and a docking device. Background Art

[0002] During the battery formation stage, the negative pressure tray is placed inside the formation cabinet. It then needs to be precisely docked with the positive pressure piping. This docking is achieved by connecting the positive pressure interface on the negative pressure tray to the positive pressure piping. Once the two are successfully docked, the air control valve opens, and the negative pressure piping begins operating, performing negative pressure formation on the battery, ensuring stable internal gas pressure and improving battery performance and quality.

[0003] However, in actual operation, conventional positive-pressure docking mechanisms often encounter some problems. Due to the possibility of errors in the assembly process of the positive-pressure docking interface of the negative-pressure tray, the positive-pressure pipeline is prone to docking inaccuracies such as skewness and misalignment during docking. This inaccurate docking can cause air leakage at the positive-pressure docking point, rendering the entire docking system ineffective. This not only affects the efficiency of battery formation, but may also have a negative impact on battery quality. Therefore, solving the assembly error problem of the positive-pressure docking interface of the negative-pressure tray and improving the accuracy and stability of the positive-pressure pipeline docking are important tasks currently faced.

[0051] like Figure 1 as well as Figure 2 An embodiment of the present invention provides a docking device 100, including a connector 10 and a connector base 20, wherein the connector 10 includes a first docking component 11 and a first guide member 12; wherein the first docking component 11 is used to dock with the connector base 20; and the first guide member 12 is sleeved on the first docking component 11.

[0052] Based on a general inventive concept of an embodiment of the present utility model, when the connecting head 10 is docked with the connecting seat 20, the first docking component 11 can move relatively in a direction away from the connecting seat 20 to form a floating gap between the first guide member 12 and the first docking component 11.

[0053] It should be noted that the first guide member 12 can be understood as an annular structure, which is sleeved on the outside of the first docking component 11 so as to play a role in constraining and guiding the first docking component 11, ensuring that the first docking component 11 maintains the correct motion trajectory during the floating process. After the first docking component 11 and the connecting seat 20 are in a docking state, a floating gap is formed between the first guide member 12 and the first docking component 11. Its "floating gap" refers to the spatial gap formed between the inner wall of the first guide member 12 and the first docking component 11 in the radial direction. This gap allows the first docking component 11 to have a certain radial degree of freedom during the docking process to cope with possible position deviations or misalignments, thereby achieving more precise and stable docking.

[0054] Furthermore, after the first docking component 11 in the connector 10 is mechanically docked with the connecting seat 20, it can move relatively in a direction away from the connecting seat 20 under the reverse mechanical contact force applied by the connecting seat 20 (that is, the first docking component 11 is not completely constrained in its axial movement freedom). This design allows the first docking component 11 to retract in the axial direction during the docking process of the connector 10, even if there is a slight position deviation or misalignment, and to achieve precise docking through the floating adjustment of the first docking component 11 while retracting; at the same time, when the first docking component 11 and the first guide member 12 are not docked, a stable connection relationship can be maintained to ensure the position accuracy of the first docking component 11 when not docked.

[0055] In summary, based on the general inventive concept of the present utility model, the floating gap between the connector 10 and the connector base 20 allows for certain positional deviations or misalignments during the docking process, which are automatically compensated for through the floating gap, thereby improving the fault tolerance and reliability of the docking, and avoiding problems such as docking skew, misalignment, and the resulting positive pressure docking leakage and failure.

[0056] In a specific embodiment, the first docking assembly 11 includes a first suction rod 111 and a first suction nozzle structure 112; the first suction rod 111 is arranged in the first guide member 12; one end of the first suction nozzle structure 112 is connected to the first suction rod 111, and the other end is used to dock with the connecting seat 20; wherein, after the first suction nozzle structure 112 docks with the connecting seat 20, the first suction rod 111 moves in a direction away from the connecting seat 20, and forms a radial floating gap between it and the first guide member 12.

[0057] like Figure 1 as well as Figure 2 The first suction rod 111 is part of the first docking assembly 11 and is located within the first guide 12. It not only supports the first suction nozzle structure 112 but also creates a floating gap during the docking process through its movement characteristics. The first suction nozzle structure 112 is another part of the first docking assembly 11. One end is connected to the first suction rod 111, and the other end is used to dock with the connecting base 20. The first suction nozzle structure 112 is a flexible seal that allows it to dock with the connecting base 20 to ensure tightness and stability.

[0058] like Figures 2 to 3 In a specific embodiment, the first suction rod 111 includes a first connecting section 1111 and a first extension section 1112 in sequence along the direction away from the connecting seat 20; the first connecting section 1111 is connected to the first suction nozzle structure 112; the first extension section 1112 includes a first part 1112a and a second part 1112b, and the outer diameter of the first part 1112a is set to be smaller than the outer diameter of the second part 1112b.

[0059] The first connecting section 1111 is the portion of the first suction rod 111 that is close to the first suction nozzle structure 112. One end of the first connecting section 1111 is directly connected to the first suction nozzle structure 112 and transmits force or displacement from the first suction nozzle structure 112. The other end of the first connecting section 1111 is connected to the first extension section 1112. The first extension section 1112 is the portion of the first suction rod 111 located after the first connecting section 1111. It further extends and passes through the first guide member 12.

[0060] As described above, first extension section 1112 comprises two portions with different outer diameters: first portion 1112a and second portion 1112b. First portion 1112a is the portion of first extension section 1112 located near first connecting section 1111 and having a smaller outer diameter. Second portion 1112b is the portion of first extension section 1112 with a larger outer diameter, located behind first portion 1112a. Specifically, the outer diameter of first portion 1112a is smaller than that of second portion 1112b, which is also smaller than the inner diameter of first guide member 12. However, the outer diameter of second portion 1112b matches the inner diameter of first guide member 12.

[0061] Through the above design, when the connector 10 and the connector base 20 are not docked, the first guide member 12 is externally positioned on the second portion 1112b. At this point, the outer diameter of the second portion 1112b matches the inner diameter of the first guide member 12, forming a tight fit (e.g., a clearance fit with a small tolerance). This tight fit ensures the stability and accuracy of the connector 10 when in motion or when not docked. In this state, the first docking assembly 11 (including the first suction rod 111 and the first suction nozzle structure 112) can remain stable.

[0062] After the connector 10 is docked with the connector base 20, due to the effect of the preset axial movement mechanism, the first docking assembly 11 can move relative to the first guide member 12 in a direction away from the connector base 20 under the reverse mechanical contact force of the connector base 20. This movement causes the second portion 1112b to detach from the first guide member 12, and the first portion 1112a, which was originally located outside the first guide member 12, to enter the interior of the first guide member 12. Because the outer diameter of the first portion 1112a is smaller than the inner diameter of the first guide member 12, a radial floating gap is formed between the two. The presence of the floating gap allows the first docking assembly 11 to be fine-tuned during the docking process to compensate for possible position deviations or misalignments, thereby improving the accuracy and reliability of the docking. Through the tightly fitting second portion 1112b and the first guide member 12, as well as the floating gap formed after docking, the position changes during the docking process can be precisely controlled, improving the accuracy of the docking.

[0063] Furthermore, the first suction rod 111 also includes a first abutting section 1113 located on the side of the first extension section 1112 away from the first connecting section 1111, and the outer diameter of the first abutting section 1113 is larger than the outer diameter of the second part 1112b; when the connecting head 10 and the connecting seat 20 are not docked, the first abutting section 1113 abuts against the first guide member 12.

[0064] It can be understood that, as mentioned above, the first suction nozzle structure 112 is responsible for direct contact with the connecting seat 20; the first extension section 1112 includes a first part 1112a and a second part 1112b with different outer diameters. Among them, the outer diameter of the second part 1112b matches the inner diameter of the first guide member 12 to form a tight fit; and the outer diameter of the first part 1112a is smaller than the inner diameter of the first guide member 12, which is used to form a floating gap after docking. The first abutment section 1113 is located at the end of the first extension section 1112, and its outer diameter is larger than the outer diameter of the second part 1112b. Since the outer diameter of the first abutment section 1113 is larger, it can effectively prevent the first suction rod 111 (or the entire connector 10) from accidentally detaching from the connecting seat 20 or other fixed structures when the first suction rod 111 is not docked, thereby improving structural stability.

[0065] In an optional solution of the embodiment of the present invention, the connector 10 further includes a first elastic member 13 , which is externally mounted on the first extension section 1112 and has one end abutting against the first guide member 12 and the other end abutting against the first connecting section 1111 .

[0066] It can be understood that the first elastic member 13 is a spring or a disc spring, etc., and its expansion and contraction direction is in the axial direction of the first docking assembly 11; at the same time, the inner diameter of the first elastic member 13 is larger than the first extension section 1112, so it is designed to be tightly and stably mounted on the first extension section 1112 without affecting the normal movement of the first extension section 1112.

[0067] When the first docking assembly 11 and the connecting base 20 are docked, the first elastic member 13 is compressed to undergo elastic deformation, providing additional pressure to the first nozzle structure 112, enabling it to be pressed more firmly against the connecting base 20. This helps to improve the stability and sealing of the docking between the first docking assembly 11 and the connecting base 20, and ensures that the docking tightness can be maintained even under certain external forces or vibrations during docking.

[0068] like Figure 2 、 Figure 4 as well as Figure 5The connecting seat 20 includes a first connecting component 21 corresponding to the first docking component 11; the first suction nozzle structure 112 includes a first docking port A, the first suction rod 111 includes a first channel B, the first connecting component 21 includes a second channel C, and the first docking port A and the first channel B are connected; when the connecting head 10 is docked with the connecting seat 20, the first connecting component 21 can extend into the first docking port A and connect the first channel B and the second channel C.

[0069] Specifically, during the initial docking process, the connector 10 is guided to the vicinity of the connector base 20 and begins the initial docking process. During this stage, the first docking port A of the first nozzle structure 112 covers and contacts the outer edge of the first connecting component 21. As the docking process continues, the first connecting component 21 gradually extends into the interior of the first docking port A. When the first connecting component 21 is fully inserted into the first docking port A, the first channel B and the second channel C are connected. The tight docking between the first nozzle structure 112 and the first connecting component 21 achieves a better seal, ensuring the continuity and stability of media transmission.

[0070] In a preferred embodiment of the present invention, an inner chamfer is provided at the opening of the first connection port A, and an outer chamfer that matches the inner chamfer is provided at the end of the first connection component 21 facing the first connection port A. The matching design of the inner chamfer and the outer chamfer helps to form a tighter seal. At the same time, the setting of the inner chamfer and the outer chamfer plays a guiding role, so that the first connection component 21 can enter the first connection port A more smoothly and accurately during the docking process. This design helps to reduce friction and resistance during docking and improve docking efficiency. In addition, during the docking process, the inner chamfer and the outer chamfer can contact each other and disperse the contact force, thereby protecting the end faces of the first connection port A and the first connection component 21 from damage, which helps to extend the service life of the components and reduce wear caused by direct rigid contact.

[0071] The first docking assembly 11 also includes a first protective sleeve 113. One end of the first protective sleeve 113 is axially sleeved over the first suction nozzle structure 112, and the other end is sleeved over the first suction rod 111. The first protective sleeve 113 is sleeved over the first suction nozzle structure 112 and the first suction rod 111 to better seal the connection between the first suction rod 111 and the first suction nozzle structure 112 and to act as a buffer for the first suction nozzle structure 112 during docking.

[0072] The connector 10 also includes a second docking component 14, and the connecting base 20 also includes a second connecting component 22; the second docking component 14 includes a second docking port D and a third channel E, and the second connecting component 22 includes a fourth channel F, and the second docking port D and the third channel E are connected; wherein, when the connector 10 is docked with the connecting base 20, the second docking port D can cover the fourth channel F, so that the fourth channel F and the third channel E are connected.

[0073] By adding the second docking component 14 and the second connecting component 22, the connection between the connector 10 and the connector base 20 becomes more complex and diversified. This design allows the transmission of multiple media channels during the same docking process, thereby improving the flexibility and versatility of the system.

[0074] When connector 10 is docked with connector base 20, first connector assembly 21 enters first connection port A, connecting first channel B and second channel C. Meanwhile, second docking port D simultaneously covers second connector assembly 22, thereby connecting third channel E and fourth channel F. This design allows for a direct connection path between two independent channels, facilitating the transfer of media. Similar to first docking assembly 11 and first connector assembly 21, the connection between second docking assembly 14 and second connector assembly 22 also requires a good seal to prevent leakage and enhance docking reliability and safety.

[0075] It should be noted that the first connecting component 21 is connected to the first connecting port A by plugging, while the second connecting port D is tightly connected to the second connecting component 22 by covering surface-to-surface contact. Since the plug-in method generally requires a high radial precision between the connecting components, if both the first connecting component 21 and the second connecting component 22 are plug-in, the relative positions of the first connecting component 21 and the second connecting component 22 require high precision, and structural interference is likely to occur during docking. The embodiment of the utility model realizes that the second connecting port D is connected by covering surface-to-surface contact, so that it only relies on a larger contact area to achieve the stability and sealing of the connection. This not only reduces the difficulty and cost of processing, but also improves the reliability and durability of the connection.

[0076] Continue reading Figure 2 and Figure 4 In an optional solution of the present invention, the first channel B and the second channel C form a positive pressure channel, and the third channel E and the fourth channel F form a negative pressure channel.

[0077] Furthermore, the connecting seat 20 also includes a connecting pipeline 23 and a control valve 24. The control valve 24 is configured to control the negative pressure channel to be connected to the connecting pipeline 23 under the action of the air pressure of the positive pressure channel.

[0078] Specifically, the positive pressure channel is designed to have a trigger condition, and the control valve 24 operates under the action of the air pressure in the positive pressure channel (the first channel B and the second channel C). When the air pressure in the positive pressure channel reaches or exceeds a certain preset value, the control valve 24 will respond to this change, thereby changing its internal state to allow the medium to flow between the negative pressure channel (the third channel E and the fourth channel F) and the connecting pipe 23. Specifically, when the air pressure of the external air source connected to the positive pressure channel rises, this change will be sensed by the control valve 24. Once the air pressure in the positive pressure channel reaches or exceeds the preset threshold of the control valve 24, the control valve 24 will change its internal state. This change may involve opening, closing, or adjusting the opening of the valve. At this time, under the action of the control valve 24, the channel between the negative pressure channel (the third channel E and the fourth channel F) and the connecting pipe 23 is adjusted to a state that allows the medium to pass through. In this way, the connecting pipe 23 is connected to the negative pressure, thereby achieving the extraction of the medium.

[0079] Furthermore, the connecting head 10 also includes a second guide member 15 and a second elastic member 16; the second docking component 14 also includes a second suction rod 141 and a second suction nozzle structure 142, and the second suction nozzle structure 142 is connected to one end of the second suction rod 141 facing the second connecting component 22; the second guide member 15 is externally mounted on the second suction rod 141; the second elastic member 16 is externally mounted on the second suction rod 141, and one end is abutted against the second suction nozzle structure 142, and the other end is abutted against the second guide member 15.

[0080] Similarly, the second elastic member 16 is positioned over the second suction rod 141, with one end abutting the second suction nozzle structure 142 and the other end abutting the second guide member 15. This design allows the connector 10 to have a certain degree of adaptability during the docking process. When the second suction nozzle structure 142 contacts the second connecting component 22 (or its corresponding component) and generates slight pressure, the second elastic member 16 elastically deforms, generating a spring force that causes the second suction nozzle structure 142 to fit tightly against the second connecting component 22, ensuring a good seal and connection.

[0081] The docking device 100 further includes a push plate 30 and a driving mechanism 40 . The connector 10 is connected to the push plate 30 . The driving mechanism 40 enables the push plate 30 to drive the connector 10 to move.

[0082] Specifically, the push plate 30 is a rigid structural member, and the connector 10 is connected to the push plate 30 to transmit the power generated by the driving mechanism 40 to the connector 10, so that the connector 10 can move according to a predetermined trajectory and speed under the drive of the push plate 30.

[0083] The driving mechanism 40 is the power source in the docking device 100, responsible for generating and controlling the movement of the push plate 30 and the connector 10.
