Description

Technical Field

[0001] This application relates to the field of battery production equipment technology, and in particular to a positioning device and a formation device. Background Technology

[0002] Cylindrical open-top batteries have a unique structure. The positive electrode plate is parallel to the battery's axis and perpendicular to the horizontal plane, while the negative electrode is the battery casing. In the formation process, the batteries need to be precisely positioned first, and then probes are used to energize the positive electrode plate and the negative electrode casing to complete the formation. However, existing positioning and energizing mechanisms are too large, resulting in significant gaps between rows of products, making it difficult to achieve the fully automated positioning and formation requirements for matrix-arranged incoming batteries.

[0003] Most equipment currently on the market is semi-automatic, capable of only semi-automatically positioning and forming single-row batteries. This semi-automatic production mode is not only inefficient but also lacks optimized space utilization, failing to meet the high efficiency and compactness requirements of large-scale automated production. Therefore, in order to improve production efficiency, optimize space utilization, and achieve fully automated production, there is an urgent need for an automated positioning and forming mechanism that can reduce the gap between pallet-loaded products and is suitable for matrix-arranged products.

Detailed Implementation

[0043] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0048] In the formation process of lithium batteries, cylindrical open-cell batteries have unique structural features. The positive electrode current plate of a cylindrical open-cell battery is parallel to the axis of the cylindrical battery and perpendicular to the horizontal plane, while the negative electrode is the battery casing. This structural design requires precise positioning of the cylindrical open-cell battery during the formation process to ensure that the probe can accurately contact the positive electrode current plate and the negative electrode casing.

[0049] Specifically, the formation process requires precise positioning of the batteries to ensure the accurate placement of each battery. Then, probes are used to energize the positive electrode plate and the negative electrode casing to complete the formation process. However, existing positioning and energizing mechanisms, due to the separate wiring design for the probe mechanism of each cylindrical open battery, result in excessively large positioning devices. This not only increases the complexity and space required but also leads to large gaps between rows of products, making it difficult to achieve fully automated positioning and formation of matrix-arranged cylindrical open batteries.

[0050] Based on this, the present application discloses a positioning device and a formation equipment, which avoids the problems of excessive gaps between batteries, difficulty in matrix arrangement, and the need to use semi-automatic equipment for formation caused by the excessively large wiring size of the positioning mechanism, thereby improving production efficiency and space utilization.

[0051] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0052] Please see Figures 1 to 4 , Figure 1 This is one of the structural schematic diagrams of the open battery 200 provided in the embodiments of this application; Figure 2 This is the second structural schematic diagram of the open battery 200 provided in the embodiments of this application; Figure 3 This is one of the structural schematic diagrams of the positioning device 100 provided in the embodiments of this application; Figure 4 This is a second structural schematic diagram of the positioning device 100 provided in this application embodiment. This application embodiment discloses a positioning device 100 for positioning an open battery 200. The open battery 200 includes a main body 201 and a cover 202. The main body 201 is cylindrical and has an opening. The cover 202 is disposed at the opening, and the plane of the cover 202 forms an angle with the bottom surface of the main body 201. The positioning device 100 includes:

[0053] The carrier assembly 1 includes a plurality of carrier slots 11, which extend along a first direction X and are spaced apart along a second direction Y. The carrier slots 11 are configured to accommodate a plurality of open batteries 200, and the plurality of open batteries 200 in any carrier slot 11 are spaced apart along the first direction X.

[0054] Multiple positioning components 2 are movably disposed on the support component 1 along the second direction Y, and the multiple positioning components 2 are arranged at intervals along the first direction X. The positioning components 2 are configured to correspond one-to-one with the support groove 11. The positioning components 2 are used to limit the position of the open battery 200 along the second direction Y.

[0055] Multiple busbar components 3 are connected one-to-one with multiple positioning components 2, and each busbar component 3 is electrically connected to an open battery 200 in each bearing slot 11. The busbar component 3 is used to supply power to the open battery 200.

[0056] The carrier assembly 1 includes multiple carrier slots 11, which extend along a first direction X and are spaced apart along a second direction Y. This allows the carrier assembly 1 to simultaneously accommodate multiple open batteries 200, enabling batch processing of the open batteries 200 and improving production efficiency.

[0057] Multiple positioning components 2 are movably disposed on the support component 1 along the second direction Y, and correspond one-to-one with the support groove 11. In actual operation, the positioning components 2 can limit the position of the open battery 200 along the second direction Y, ensuring that the battery maintains a stable position during the formation process, thereby improving the accuracy and quality of formation.

[0058] Furthermore, in cooperation with the support component 1, the positioning component 2 can fix the open battery 200 in a predetermined position after it is placed into the support slot 11, reducing the positional deviation of the battery during the formation process and lowering the risk of formation failure due to inaccurate positioning. At the same time, the orderly arrangement and precise control of the positioning component 2 also provide reliable positioning assurance for the subsequent power supply operation of the combiner component 3.

[0059] The current collector assembly 3 is responsible for supplying power to the open battery 200 and is one of the core components for battery formation. The current collector assembly 3 is connected one-to-one with the positioning assembly 2, and each current collector assembly 3 is electrically connected to each open battery 200 in the support slot 11, ensuring that the current can be stably and evenly transmitted to each open battery 200, meeting the electrical requirements of the battery formation process. The close connection between the current collector assembly 3 and the positioning assembly 2 allows the current collector assembly 3 to accurately establish an electrical connection with the open battery 200 while the positioning assembly 2 fixes the position of the open battery 200, improving the reliability and stability of the power supply.

[0060] The busbar assembly 3 and the positioning assembly 2 are connected in a clever one-to-one correspondence, eliminating the complex design of traditional designs where each probe mechanism requires separate wiring. In traditional designs, the independent wiring of each probe mechanism not only results in messy wiring but also occupies a large amount of space, limiting the miniaturization and integration of the positioning device 100. This optimized wiring method allows the busbar assembly 3 to simultaneously power multiple open batteries 200 within a limited space. By centrally managing the wiring, the simplified wiring layout of the busbar assembly 3 makes the entire positioning device 100 more compact, providing more space for the supporting assembly 1 and the positioning assembly 2, thereby further reducing the gap between each row of products.

[0061] Furthermore, this design of the busbar assembly 3 helps reduce production costs and maintenance complexity. In the manufacturing process, reducing wiring means reducing material usage and processing steps, thereby lowering production costs. In the routine maintenance of the positioning device 100, the simplified wiring layout also makes troubleshooting and repair more convenient and faster, improving the reliability and maintainability of the positioning device 100.

[0062] Thus, the positioning device 100 provided in this application, through the arrangement of the bearing component 1, the control of the positioning component 2, and the efficient power supply of the bus component 3, solves the problem of the positioning and power supply mechanism being too large and difficult to achieve matrix arrangement in the prior art, optimizes the space utilization of the positioning device 100, reduces production costs, and improves the efficiency and quality of the positioning formation of the open battery 200.

[0063] Please see Figures 5 to 7 , Figure 5 This is one of the structural schematic diagrams of the positioning component 2 and the busbar component 3 provided in the embodiments of this application; Figure 6 This is a second schematic diagram of the structure of the positioning component 2 and the busbar component 3 provided in the embodiments of this application; Figure 7 This is the third schematic diagram of the structure of the positioning component 2 and the busbar component 3 provided in the embodiments of this application. In some embodiments, the busbar component 3 includes: a busbar bracket 31, which is connected to the positioning component 2; a plurality of connecting units 32, which are disposed on the busbar bracket 31 and are arranged at intervals along a first direction X. The plurality of connecting units 32 are respectively disposed in correspondence with the open batteries 200 in the corresponding bearing grooves 11, and are configured to be electrically connected to the open batteries 200 to supply power to the open batteries 200; and a busbar unit 33, which is disposed on the busbar bracket 31. The plurality of connecting units 32 are all electrically connected to the busbar unit 33, and the busbar unit 33 is used to be electrically connected to an external power supply device to supply power to the connecting units 32.

[0064] The busbar bracket 31 is connected to the positioning component 2, providing stable mechanical support and structural frame for the entire busbar component 3. This ensures that the busbar component 3 maintains a stable position and orientation during operation, thereby improving the reliability of the electrical connection. Simultaneously, the design of the busbar bracket 31 effectively integrates multiple connection units 32, allowing them to be arranged in an orderly manner in space, further optimizing the layout of the entire positioning device 100.

[0065] Multiple connecting units 32 are arranged at intervals along the first direction X, and are configured one-to-one with the open batteries 200 in the corresponding support slots 11. This ensures that each connecting unit 32 can accurately establish an electrical connection with its corresponding open battery 200, guaranteeing that current can be stably and evenly transmitted to each open battery 200. The spaced arrangement of the connecting units 32 not only improves the reliability of the electrical connection but also avoids mutual interference between the connecting units 32, further improving the operational stability and safety of the positioning device 100.

[0066] The combiner unit 33 is mounted on the combiner bracket 31 and is electrically connected to multiple connection units 32. As the power supply hub of the entire combiner assembly 3, the combiner unit 33 is responsible for distributing electrical energy from external power supply equipment to each connection unit 32, thereby enabling simultaneous power supply to multiple open-cell batteries 200. This centralized power supply not only simplifies the wiring layout, reduces wiring complexity and space occupation, but also improves the efficiency and reliability of power transmission.

[0067] The combiner unit 33 makes the entire power supply system more modular and integrated. By integrating the power supply lines of multiple connection units 32 into the combiner unit 33, the number and length of lines are reduced, and mutual interference and power loss between lines are decreased. At the same time, the modular design also facilitates the maintenance and replacement of the combiner unit 33, improving the maintainability and reliability of the positioning device 100.

[0068] Please see Figures 8 to 10 , Figure 8 This is one of the structural schematic diagrams of the connection unit 32 provided in the embodiments of this application; Figure 9 This is a second schematic diagram of the structure of the connection unit 32 provided in the embodiments of this application; Figure 10This is a third schematic diagram of the structure of the connection unit 32 provided in this application embodiment. In some embodiments, the connection unit 32 includes a positive probe 321, a negative probe 322, a connection circuit board 323, and a first connection terminal 324. The positive probe 321 is disposed on the side of the connection circuit board 323 facing the positioning component 2, and the positive probe 321 is located on the upper part of the connection circuit board 323. The first end of the positive probe 321 is configured to contact the cover 202. The negative probe 322 is disposed on the side of the connection circuit board 323 facing the positioning component 2, and the negative probe 322 is located on the lower part of the connection circuit board 323. The first end of the negative probe 322 is configured to contact the outer peripheral surface of the main body 201. The connection circuit board 323 is electrically connected to the second end of the positive probe 321 and the second end of the negative probe 322, and the connection circuit board 323 is electrically connected to the first connection terminal 324, which is used to connect the busbar unit 33.

[0069] The positive probe 321 is located on the upper part of the connecting circuit board 323 facing the positioning component 2, with its first end contacting the cover 202. The negative probe 322 is located on the lower part of the same side of the connecting circuit board 323, with its first end contacting the outer peripheral surface of the main body 201. This layered design ensures that the positive and negative probes 322 accurately contact the corresponding polarity parts of the open battery 200, effectively avoiding short circuits or poor contact caused by incorrect positioning, thereby ensuring stable current transmission.

[0070] The connecting circuit board 323 not only supports the positive and negative probes 322, but also acts as an intermediary for electrical connections, connecting the positive probe 321 and the negative probe 322 to the first connecting terminal 324, and then to the bus unit 33. This simplifies the electrical connection path, reduces circuit complexity, improves the efficiency of power transmission, and also facilitates the maintenance and replacement of the connecting unit 32.

[0071] Please see Figures 11 to 13 , Figure 11 This is one of the structural schematic diagrams of the bus component 3 provided in the embodiments of this application; Figure 12 This is a second schematic diagram of the structure of the bus component 3 provided in the embodiments of this application; Figure 13This is the third schematic diagram of the structure of the busbar assembly 3 provided in the embodiments of this application. In some embodiments, the busbar unit 33 includes: a busbar circuit board 331 disposed on the busbar bracket 31; a plurality of second connection terminals 332 disposed on the busbar circuit board 331 and electrically connected to the busbar circuit board 331, the plurality of second connection terminals 332 being arranged at intervals along a first direction X, and the plurality of second connection terminals 332 being electrically connected to a plurality of first connection terminals 324 in a one-to-one correspondence; and a busbar terminal 333 disposed on the busbar circuit board 331 and electrically connected to the busbar circuit board 331, the busbar terminal 333 being configured to be electrically connected to an external power supply device.

[0072] The busbar circuit board 331 is mounted on the busbar bracket 31, providing a stable mechanical support and electrical connection foundation for the entire busbar unit 33. The structure and layout of the circuit board itself ensure efficient power transmission, while also possessing good heat dissipation performance and electromagnetic interference resistance, thereby improving the stability and reliability of the positioning device 100.

[0073] Multiple second connection terminals 332 are arranged at intervals along the first direction X on the busbar circuit board 331 and are electrically connected to the busbar circuit board 331. Each second connection terminal 332 corresponds one-to-one with a first connection terminal 324 in the connection unit 32, achieving precise electrical connection. In this way, each connection unit 32 can stably obtain power from the busbar unit 33 and transmit the power to the corresponding open battery 200. This corresponding connection method not only ensures the accuracy of power transmission but also improves connection efficiency and reduces power loss and failure risk caused by connection errors.

[0074] The electrical connection between the bus terminal 333 and the bus circuit board 331 ensures that electrical energy input from external power supply equipment can smoothly enter the bus circuit board 331 and be distributed to each connection unit 32 through the second connection terminal 332, ultimately achieving simultaneous power supply to multiple open batteries 200. This improves the centralization and controllability of power supply, facilitates monitoring and management of the entire power supply system, and ensures the stability and safety of power transmission.

[0075] Furthermore, this modular design makes the maintenance and replacement of the bus unit 33 more convenient. When a second connection terminal 332 or bus terminal 333 fails, the corresponding component can be quickly located and replaced without overhauling the entire bus unit 33, thereby reducing the downtime of the positioning device 100 and improving production efficiency.

[0076] Please see Figures 11 to 13In some embodiments, the busbar support 31 includes a first support 311 and a second support 312, which are arranged at intervals from bottom to top in a vertical direction. The first support 311 is configured to connect to the connecting unit 32, and the second support 312 is configured to connect to the busbar unit 33.

[0077] The first bracket 311 is configured to connect to the connection unit 32, providing stable mechanical support and an electrical connection foundation for the connection unit 32. This ensures that the connection unit 32 maintains a stable position and orientation during operation, thereby improving the reliability of the electrical connection with the open battery 200. Simultaneously, the independent design of the first bracket 311 facilitates the installation, commissioning, and maintenance of the connection unit 32, allowing for more convenient operation of the connection unit 32 without affecting the normal operation of the combiner unit 33.

[0078] The second bracket 312 is configured to connect the combiner unit 33, providing a support and connection platform for the combiner unit 33. This allows the combiner unit 33 to be more stably integrated onto the combiner bracket 31, ensuring the stability and safety of power transmission. The second bracket 312 is positioned above the first bracket 311, creating a spatial hierarchy between the combiner unit 33 and the connection unit 32, avoiding mutual interference between them. It also provides a reasonable path for the gradual distribution of power, saving space occupied by the positioning device 100.

[0079] Please see Figures 5 to 7 In some embodiments, the positioning component 2 includes: a positioning bracket 21, which is slidably disposed on the bearing component 1 along the second direction Y and extends along the first direction X; and a plurality of positioning units 22 disposed on the positioning bracket 21, which are spaced apart along the first direction X, and each of the plurality of positioning units 22 corresponds to an open battery 200. The positioning units 22 are used to limit the position of the open battery 200 along the second direction Y.

[0080] The positioning bracket 21 is slidably disposed on the support assembly 1 along the second direction Y and extends along the first direction X. During the positioning process, the positioning bracket 21 moves along the second direction Y under the action of the drive mechanism, gradually approaching the open battery 200. When the positioning unit 22 contacts the open battery 200, the positioning bracket 21 continues to move, so that the positioning unit 22 abuts against a specific part of the open battery 200, thereby ensuring that the position of the open battery 200 in the support groove 11 is accurately fixed, thus meeting the position requirements of the open battery 200 during the formation process. In this way, the positioning assembly 2 can not only adapt to the initial positional differences of the open battery 200 in the support groove 11, but also achieve fine-tuning of the position of the open battery 200 through abutment, ensuring that each open battery 200 can be accurately positioned, providing a reliable physical guarantee for subsequent electrical connection and formation operations.

[0081] Please see Figures 5 to 7 In some embodiments, the positioning unit 22 includes: a first positioning block 221, which is disposed on the positioning bracket 21 and configured to restrict the degree of freedom of the cover 202 of the open battery 200 along the second direction Y; and a second positioning block 222, which is disposed on the positioning bracket 21 and configured to restrict the degree of freedom of the body 201 of the open battery 200 along the second direction Y.

[0082] The positioning component 2 includes a first positioning block 221 and a second positioning block 222. The first positioning block 221 restricts the degree of freedom of the cover 202 of the open battery 200 along the second direction Y, while the second positioning block 222 specifically restricts the degree of freedom of the body 201 of the open battery 200 along the second direction Y. During the positioning process, when the positioning bracket 21 moves along the second direction Y, the first positioning block 221 contacts the cover 202 of the open battery 200, and by continuously moving the positioning bracket 21, the first positioning block 221 abuts against the cover 202. This abutting method ensures that the position of the cover 202 in the second direction Y is accurately fixed, preventing the cover 202 from shifting due to external forces.

[0083] Similarly, the second positioning block 222 acts on the main body 201 of the open battery 200, restricting the movement of the main body 201 in the second direction Y, thus ensuring the stability of the open battery body 201. This design, where the first positioning block 221 and the second positioning block 222 act on different parts of the open battery 200, allows for more precise control of the open battery 200's position, ensuring that the open battery 200 maintains a stable posture throughout the formation process.

[0084] Optionally, the first positioning block 221 can be customized according to the shape and tilt angle of the cover 202 to ensure better fit to the cover 202 during contact and provide firm support. Similarly, the second positioning block 222 can also be adjusted according to the outer peripheral shape of the body 201 to achieve a more effective restraining effect. This targeted design improves the accuracy and reliability of positioning, reduces electrical connection problems caused by battery position misalignment, thereby improving the formation success rate and product quality.

[0085] Please see Figure 5 In some embodiments, the second positioning block 222 has a guide ramp that is inclined outward in the direction pointing toward the busbar assembly 3 to form a flare.

[0086] The second positioning block 222 is provided with a guide slope, which is inclined outward in the direction pointing towards the busbar assembly 3 to form a flared structure. Specifically, the guide slope is inclined outward in the direction pointing towards the busbar assembly 3 to form a structure with a gradually widening opening. The flared opening can effectively expand the initial area of ​​contact between the positioning block and the open battery 200. Even if there is a certain deviation in the initial position of the open battery 200, the flared structure can smoothly guide the open battery 200 into the positioning area of ​​the second positioning block 222.

[0087] As the positioning bracket 21 moves toward the battery, the larger opening end of the flared structure first contacts the open battery body 201. The inclination angle of the guide ramp allows the second positioning block 222 to contact the open battery body 201 from a wider range. After contacting the battery, the guide ramp gradually pushes the open battery body 201 toward the predetermined position as the positioning bracket 21 continues to move, ensuring that the degree of freedom of the open battery body 201 in the second direction Y is effectively restricted.

[0088] The flared design not only improves positioning flexibility but also reduces the risk of positioning failure due to inaccurate positioning of the open battery 200. The flared design also allows the second positioning block 222 to have a certain degree of self-adjustment capability when it contacts the open battery 200, thereby better conforming to the shape of the main body 201 of the open battery 200 and improving positioning accuracy and reliability.

[0089] Please see Figure 3In some embodiments, the positioning device 100 includes a movable structure 4, which comprises a movable part and a fixed part. The fixed part is disposed on the support component 1, and the movable part is movably disposed on the fixed part along the second direction Y. The movable part is connected to multiple positioning components 2 to drive the positioning components 2 to move along the second direction Y. The introduction of the movable structure 4 realizes the relative movement between the positioning components 2 and the support component 1, enabling the positioning components 2 to move stably on the support component 1 without affecting the stability of the support component 1 itself, thereby improving the applicability and versatility of the entire positioning device 100.

[0090] Furthermore, the rational design of the moving structure 4 also helps to optimize space utilization. By connecting the positioning component 2 and the supporting component 1 through the moving structure 4, the space occupied by the positioning component 2 in the non-working state can be effectively reduced, making the layout of the entire positioning device 100 more compact, which is conducive to achieving efficient battery positioning and formation operations in a limited space.

[0091] Please see Figure 3 In some embodiments, the fixed part is a slide rail 41, which is disposed on the bearing component 1 and extends along the second direction Y. The moving part is a slider 42, which is slidably disposed on the slide rail 41 and is connected to multiple positioning components 2. The moving structure 4 also includes a driving member 43, which is disposed on the bearing component 1 and connected to the slider 42 so that the slider 42 moves along the extension direction of the slide rail 41.

[0092] The fixed part is a slide rail 41, which is disposed on the bearing component 1 and extends along the second direction Y, providing a stable guide rail for the moving part. The slide rail 41 ensures that the positioning component 2 can move along the correct path and avoids deviation during movement. The moving part is a slider 42, which is slidably disposed on the slide rail 41 and connected to multiple positioning components 2. The sliding of the slider 42 on the slide rail 41 allows the positioning component 2 to move smoothly along the second direction Y. The connection between the slider 42 and the positioning component 2 ensures efficient force transmission, enabling the positioning component 2 to move accurately according to a preset path and speed.

[0093] The moving structure 4 also includes a drive component 43, which is disposed on the supporting component 1 and connected to the slider 42. The drive component 43 drives the slider 42 to move along the slide rail 41, thus achieving automated and precise control of the movement of the positioning component 2. The automated operation of the drive component 43 reduces manual intervention and improves the level of automation and consistency in production.

[0094] Please see Figure 2 , Figure 14 , Figure 15 and Figure 16 , Figure 14This is one of the structural schematic diagrams of the support component 1 supporting the open battery 200 provided in the embodiments of this application; Figure 15 This is the second schematic diagram of the structure of the support component 1 supporting the open battery 200 provided in the embodiments of this application; Figure 16 This is the third schematic diagram of the structure of the support assembly 1 supporting the open battery 200 provided in the embodiments of this application. In some embodiments, the open battery 200 further includes a cup 203, which is configured to support the main body 201. The outer surface of the cup 203 is provided with a guide groove 2031. The support assembly 1 includes a support plate 12 and a plurality of guide members 13. A plurality of support grooves 11 are disposed on the support plate 12, and a plurality of guide members 13 are disposed on the upper surface of the support plate 12. The guide members 13 extend along the first direction X. The plurality of guide members 13 are correspondingly disposed with the plurality of support grooves 11. The guide members 13 fit into the opening of the support groove 11. The guide members 13 are configured to extend into the guide groove 2031 so that the cup 203 can slide along the extending direction of the guide member 13.

[0095] The cup 203 is used to support the main body 201 of the open battery 200, and the outer surface of the cup 203 is provided with a guide groove 2031. The guide groove 2031 provides a guiding path for the cup 203 to slide along the extension direction of the guide member 13. The guide member 13 in the support assembly 1 is disposed on the upper surface of the support plate 12 and extends along the first direction X, corresponding one-to-one with the support groove 11. The guide member 13 fits against the opening of the support groove 11, ensuring that the cup 203 can be accurately aligned when placed into the support groove 11 and slide along the guide member 13.

[0096] The guide member 13 extends into the guide groove 2031, allowing the cup 203 to slide smoothly along the extension direction of the guide member 13. This not only improves the sliding stability of the cup 203 but also simplifies the placement process and increases production efficiency. On automated production lines, the cup 203 can be quickly slid into the bearing groove 11 via a mechanical device, reducing the need for manual intervention and improving the automation level and consistency of production. Simultaneously, the cooperation between the guide member 13 and the guide groove 2031 can withstand a certain lateral force, ensuring that the cup 203 will not detach from the guide path due to external forces during sliding, further enhancing the stability of the cup 203.

[0097] In some embodiments, the carrier component 1 further includes a limiting structure movably disposed on the carrier plate 12 along the second direction Y. The limiting structure has a limiting state and an avoidance state. When the limiting structure is in the limiting state, the limiting structure is configured to prevent the open battery 200 from leaving the carrier groove 11 along the first direction X. When the limiting structure is in the avoidance state, the limiting structure is configured to allow the open battery 200 to leave the carrier groove 11 along the first direction X.

[0098] The limiting structure is movably disposed on the support plate 12 along the second direction Y, and has two working modes: a limiting state and an avoidance state. When in the limiting state, the limiting structure can prevent the open battery 200 from leaving the support groove 11 along the first direction X, providing support and positioning for the open battery 200, ensuring the stability of the position of the open battery 200 during the formation process, thereby ensuring the reliability of the electrical connection and the smooth progress of the formation process.

[0099] When in an avoidance state, the limiting structure allows the open battery 200 to disengage from the support groove 11 along the first direction X. This allows the open battery 200 to be easily and quickly removed from the support groove 11 when it needs to be replaced, improving the operability of the positioning device 100 and making the production process smoother.

[0100] Optionally, the limiting structure may consist of two limiting strips extending along the second direction Y and multiple limiting blocks respectively disposed on the two limiting strips. When the limiting structure is in the limiting state, the limiting blocks block the two opposite outlets of the corresponding bearing groove 11 along the first direction X, thereby preventing the open battery 200 from leaving the bearing groove 11 along the first direction X. When the limiting structure is in the avoidance state, the limiting strips can drive the limiting blocks to move along the second direction Y, thereby allowing the limiting blocks to avoid the two opposite outlets of the corresponding bearing groove 11 along the first direction X, allowing the open battery 200 to leave the bearing groove 11 along the first direction X.

[0101] In some embodiments, the carrier component 1 further includes a reset structure disposed on the carrier plate 12, the reset structure being connected to the limiting structure, and the reset structure being configured to drive the limiting structure to move from the avoidance state to the limiting state.

[0102] The reset structure is located on the support plate 12 and connected to the limiting structure, enabling it to automatically return the limiting structure from the avoidance state to the limiting state. In actual operation, when the open battery 200 needs to be placed into or removed from the support slot 11, the limiting structure is switched to the avoidance state, at which point the reset structure begins to store energy. Once the battery placement or removal operation is completed, the reset structure releases energy and automatically returns the limiting structure to the limiting state without manual intervention, effectively preventing battery displacement or detachment due to forgetting to return to the limiting state.

[0103] Optionally, the reset structure can be a spring structure, a spring sheet structure, or an electromagnetic structure, and the embodiments of this application do not limit this.

[0104] The second aspect of this application provides a formation apparatus, which includes a positioning device 100 according to the first aspect of this application. It should be noted that the positioning device 100 in the formation apparatus has the same structure as any of the positioning devices 100 in the above embodiments and can bring the same or similar beneficial effects. For details, please refer to the descriptions in the above embodiments; these will not be repeated here.

[0105] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
