Description

Technical Field

[0001] This application relates to the field of battery technology, and in particular to a cell baking device. Background Technology

[0002] Baking is one of the processes for removing internal moisture from the cells of solid-state batteries (hereinafter referred to as cells). Currently, multiple cells are typically placed in layers within a baking oven using a stacking fixture for batch drying. After baking, the moisture content of the cells needs to be sampled and tested to assess the drying effect and ensure batch quality consistency; however, moisture testing of cells is a destructive test, and random sampling is usually used. In related technologies, the baking process also suffers from low efficiency or low flexibility in cell sampling. Utility Model Content

[0003] In view of the above problems, this application provides a battery cell baking device, which aims to improve the efficiency of battery cell sampling inspection or improve the efficiency of sampling inspection.

[0004] This application provides a battery cell baking device, which includes a furnace body, multiple supporting devices, and a conveying device. The furnace body has a baking cavity and a material inlet communicating with the baking cavity. Multiple shelves are provided inside the baking cavity, and the multiple shelves are arranged sequentially at intervals along a first direction. Each supporting device is placed on a shelf. The supporting device is used to support the battery cell. The conveying device can extend into the baking cavity through the material inlet and can remove any supporting device from the material inlet.

[0005] This embodiment features multiple shelves arranged at intervals along a first direction within the baking cavity of the oven. Each shelf holds a corresponding support device for the battery cells. A conveying device extends into the baking cavity through a feeding port and removes any support device from the feeding port. Thus, when sampling of the battery cells is required, the conveying device can remove the support device corresponding to the target layer from the feeding port, enabling independent sampling of any layer of battery cells. Each support device is independent and placed on its corresponding shelf, allowing for flexible selection of any layer for sampling according to inspection needs. This improves the flexibility of the sampling operation and shortens the operation time for a single sampling, thereby increasing the efficiency of battery cell sampling. Furthermore, random sampling can be performed on any layer, making the sampling more representative and statistically significant, and more accurately reflecting the overall baking effect of the batch.

[0006] This application provides another battery cell baking apparatus, which includes a furnace body and a conveying device. The furnace body has a baking cavity and a material removal port communicating with the baking cavity. Multiple shelves are provided inside the baking cavity, arranged sequentially at intervals along a first direction. Each shelf is used to hold one carrying device. The conveying device can extend into the baking cavity through the material removal port and can remove any carrying device from the port. This improves the flexibility of the sampling inspection operation and shortens the operation time of a single sampling inspection, thereby helping to improve the sampling inspection efficiency of battery cells.

[0007] In some embodiments, the first direction is vertical; the conveying device is used to move the carrier upward so that the carrier separates from the corresponding shelf; the conveying device is also used to move the carrier horizontally toward the feeding port. This reduces metal debris or particles generated by friction and wear on the carrier, thereby reducing the risk of short circuits caused by metal particles falling onto the battery cells below.

[0008] In some embodiments, the shelf is provided with an engagement space communicating with the material inlet; the conveying device can extend from the material inlet into the engagement space and engage with the corresponding carrying device.

This is beneficial for further improving the stability and reliability of signal transmission.

[0012] In some embodiments, each support includes a mounting plate and a plurality of support blocks mounted on the mounting plate. The support blocks are spaced apart along the length of the mounting plate to support the load-bearing device. A first electrical connector and a second electrical connector are respectively mounted on the mounting plate of the corresponding support and located between two adjacent support blocks. This arrangement of the first and second electrical connectors between adjacent support blocks makes their positions more concealed, less susceptible to external impacts, and helps to improve the service life of the electrical connectors.

[0013] In some embodiments, the first electrical connector is a probe mechanism, and the third electrical connector is a probe plate; the second electrical connector is a probe mechanism, and the fourth electrical connector is a probe plate; the probe mechanism includes multiple probes, and the probe plate has multiple contact pads, with each contact pad corresponding to one of the probes. This improves the connection reliability of the first and second electrical connectors and enhances ease of use.

[0014] In some embodiments, the support frame is provided with a first limiting portion, which cooperates with a second limiting portion of the carrier device to restrict the horizontal movement of the carrier device. This reduces accidental displacement of the carrier device during baking, and helps improve the alignment accuracy and contact reliability between the probe and the contact pad.

[0015] In some embodiments, the first limiting portion is a limiting guide post, and the second limiting portion is a limiting guide hole; the side of the shelf that supports the carrier device is a support surface; the limiting guide post protrudes from the support surface and can be inserted into the limiting guide hole to guide the carrier device to a predetermined position when the carrier device is placed on the shelf.

This reduces the risk of the carrier device slipping during movement.

[0018] In some embodiments, the support device includes a support base and a plurality of brackets disposed on the support base; the support base and the shelf are detachably disposed; the plurality of brackets are arranged side by side on the support base, and each bracket is detachably connected to the support base; each bracket is used to support at least one battery cell.

Thus, by distributing the large surface of the battery cell opposite to the support plate, problems such as misalignment or bending between electrodes can be reduced, which helps to improve the consistency of the battery cell baking effect.

[0020] In some embodiments, the cell baking equipment further includes a feeding device; the feeding device is used to remove the tray from the support substrate; the feeding device is also used to remove the cell from the tray. This helps to improve cell sampling efficiency and reduces the risk of damage to the cell caused by human operation.

[0021] In some embodiments, the unloading device includes a hook and an adsorption part; the hook is used to extend into the bracket to lift the battery cell of the bracket; the adsorption part is used to adsorb onto the upper surface of the battery cell lifted by the hook.

[0034] Baking is one of the processes for removing moisture from the cells of solid-state batteries (hereinafter referred to as cells). Currently, multiple cells are typically placed in layers in a baking oven using a stacked fixture for batch drying. After baking, the moisture content of the cells needs to be sampled and tested to evaluate the drying effect. However, moisture testing of solid-state batteries is usually a destructive test, and random sampling is generally used. The layers of the existing fixtures are stacked in a closed manner, and when a specific layer of cells needs to be sampled, the target layer cannot be directly removed. Baking must be interrupted and the entire fixture disassembled before sampling can be performed, making the random sampling of cells inefficient.

[0035] Based on the above considerations, and to improve the efficiency of battery cell sampling inspection, a battery cell baking device was designed after in-depth research. Multiple shelves are arranged at intervals along a first direction within the baking cavity of the oven. Each shelf holds a corresponding support device for the battery cell. A conveying device is provided that can extend into the baking cavity through a feeding port and remove any support device from the feeding port. In this way, each support device is independently placed on its corresponding shelf, and the conveying device can individually remove any support device. This allows for individual sampling of the target layer of battery cells during the baking process, enabling more flexible sampling operations and thus improving the efficiency of battery cell sampling inspection.

[0036] The cell baking equipment disclosed in this application can be used, but is not limited to, in the production and manufacturing process of solid-state batteries. A battery production system can be constructed using the cell baking equipment disclosed in this application.

[0037] This application provides a cell baking device that can be applied to the baking process in a battery production line. This cell baking device can be used independently or combined with a feeding device, unloading device, conveying device, etc., to form an automated battery production line.

[0038] In some embodiments, refer to Figures 1 to 4 This application provides a battery cell baking apparatus 10. The battery cell baking apparatus 10 includes an oven body 11, a plurality of supporting devices 20, and a conveying device 13. The oven body 11 has a baking cavity 111 and a feeding port 112 communicating with the baking cavity 111. A plurality of shelves 12 are provided inside the baking cavity 111, and the plurality of shelves 12 are arranged sequentially at intervals along a first direction. Each supporting device 20 is placed on a corresponding shelf 12. The supporting device 20 is used to support the battery cell 30. The conveying device 13 can extend into the baking cavity 111 through the feeding port 112 and can remove any one of the supporting devices 20 from the feeding port 112.

[0039] The furnace body 11 is the main structure providing the baking cavity 111, which is a closed or sealable space for accommodating the carrier device 20 and baking and drying the battery cells 30 on the carrier device 20. The heating device can be located in the furnace body 11, on the carrier device 20, or on other devices; no specific limitation is made here. The furnace body 11 has a material inlet 112, which communicates with the baking cavity 111 for allowing the carrier device 20 to enter and exit the baking cavity 111. An furnace door can be provided at the material inlet 112 for opening or closing the material inlet 112.

[0040] The shelf 12 is a support structure disposed within the baking cavity 111, used to support the load-bearing device 20. Each shelf 12 can independently support one load-bearing device 20. There are multiple shelves 12, arranged sequentially at intervals along a first direction. The first direction can be vertical, and the vertical direction can be as follows: Figure 1 As shown in z. In any case, the number of shelves 12 can be two, three, four, five, six or more.

[0041] The carrier device 20 is used to carry the battery cell 30. That is, the carrier device 20 serves as the direct carrier of the battery cell 30. It is generally a tooling with positioning grooves or clamping structures. In this way, the carrier device 20 can constrain the relative position of the battery cell 30, and the carrier device 20 and the battery cell 30 located on the carrier device 20 can be gripped and transferred as a whole. The carrier device 20 can be a blister tray or an adjustable clamp bracket, etc.

[0042] The support device 20 and the shelf 12 can be separated. That is, the support device 20 and the shelf 12 can work together by non-permanent connection methods such as mounting, sliding, plug-in or detachable fasteners. In this way, the support device 20 can be stably placed in the shelf 12 for static placement or testing, and can also be removed as a whole at any time.

[0043] Any one of the multiple carrier devices 20 refers to any one of the multiple carrier devices 20, that is, the transport device 13 takes out any one of the carrier devices 20 of any layer without being affected by the carrier devices 20 of other layers.

[0044] The conveying device 13 can extend into the baking cavity 111 through the feeding port 112 and can remove the carrying device 20 from the feeding port 112. The conveying device 13 can be a robotic arm, or it can be a logistics trolley in conjunction with a lifting device and a picking and placing mechanism, or other picking mechanisms 133, etc.

[0045] In this embodiment, multiple shelving units 12 are arranged at intervals along a first direction within the baking cavity 111 of the furnace body 11. Each shelving unit 12 holds a corresponding support device 20, which carries the battery cell 30. A conveying device 13 is provided to extend into the baking cavity 111 through the material inlet 112 and remove any support device 20 from the material inlet 112. Thus, when it is necessary to sample the battery cell 30, the support device 20 corresponding to the target layer can be removed from the material inlet 112 by the conveying device 13, enabling independent sampling of any layer of battery cell 30. Each support device 20 is independent and placed on its corresponding shelving unit 12, allowing for flexible selection of any layer for sampling according to sampling requirements. This improves the flexibility of the sampling operation and shortens the operation time of a single sampling, thereby helping to improve the sampling efficiency of the battery cell 30.

[0046] In addition, random sampling can be carried out on any layer, making the sampling more representative and statistically significant, and more accurately reflecting the overall baking effect of the batch.

[0047] The support device 20 and the furnace body 11 are separable, meaning that the support device 20 can be sold independently of other components. Based on this, please refer to... Figures 1 to 4This application provides a battery cell baking device 10, which includes a furnace body 11 and a conveying device 13. The furnace body 11 has a baking cavity 111 and a material inlet 112 communicating with the baking cavity 111. The baking cavity 111 is provided with a plurality of shelves 12, which are arranged sequentially at intervals along a first direction. Each shelf 12 is used to hold a carrier device 20. The conveying device 13 can extend into the baking cavity 111 through the material inlet 112 and can remove any carrier device 20 from the material inlet 112. The technical solution of this embodiment has the same technical effects as the previous embodiment, and will not be described again here.

[0048] In some embodiments, please refer to Figures 1 to 4 The first direction is vertical. The conveying device 13 is used to move the carrying device 20 upward so that the carrying device 20 is separated from the corresponding shelf 12. The conveying device 13 is also used to move the carrying device 20 horizontally toward the material receiving port 112.

[0049] like Figure 1 As shown in Figure z, the first direction, the vertical direction, refers to the arrangement of multiple shelves 12 at intervals along the vertical direction (i.e., the direction of gravity), defining a multi-layered structure. The first direction can also be understood as the height direction of the furnace body; the conveying device 13 moves the supporting device 20 upward, meaning that the conveying device 13 first lifts the supporting device 20 upward along the vertical direction, causing the supporting device 20 to detach from the support of the shelf 12. Then, the supporting device 20 moves horizontally towards the feeding port 112, so that the supporting device 20 is removed through the feeding port 112.

[0050] Baking equipment is relatively large overall, such as Figure 1 As shown, four baking cavities 111 are illustrated. For example, the dimensions of a single baking cavity 111 are typically greater than 1000 mm in all three dimensions (length, width, and height). Thus, when the support device 20 carries the battery cell 30, its overall weight is relatively heavy, and the contact surface between the shelf 12 and the support device 20 experiences significant normal pressure. If horizontal relative sliding occurs between the two at this time, the contact surfaces will rub against each other, causing the contact surfaces to peel off or grind out metal fragments or particles.

[0051] In this embodiment, the conveying device 13 first lifts the bearing device 20 vertically upwards, so that the bearing device 20 is removed from the shelf 12. Then the bearing device 20 moves horizontally toward the feeding port 112. In this way, metal chips or particles generated by friction and wear of the bearing device 20 can be reduced, thereby reducing the risk of short circuits caused by metal particles falling to the lower battery cell 30.

[0052] In some embodiments, please refer to Figure 1 and Figure 2The shelf 12 is provided with an engagement space 120 communicating with the material inlet 112. The conveying device 13 can extend from the material inlet 112 into the engagement space 120 and engage with the corresponding support device 20.

[0053] The engagement space 120 is a reserved area on the shelf 12 for the material handling mechanism 133 of the conveying device 13 to extend into. The engagement space 120 communicates with the material handling port 112, allowing the conveying device 13 to extend directly from the material handling port 112 into the engagement space 120 and engage with the carrying device 20 within the engagement space 120. The engagement can be lifting, clamping, or adsorption, etc. In some examples, the engagement space 120 and the material handling port 112 are arranged horizontally opposite each other, so that the material handling arm 133b extends in a straight line.

[0054] This embodiment provides a connecting space 120 that communicates with the material handling port 112 in the shelving frame 12, allowing the conveying device 13 to extend directly into the periphery of the target bearing device 20. This helps to shorten the picking and placing path and improve picking and placing efficiency.

[0055] In some embodiments, please refer to Figure 3 and Figure 4 The battery cell baking equipment 10 includes an electrical control device. The shelf 12 is equipped with a first electrical connection assembly 15, and the electrical control device is electrically connected to the first electrical connection assembly 15. The support device 20 is equipped with a heating assembly, a temperature measuring assembly, and a second electrical connection assembly 24; the second electrical connection assembly 24 is electrically connected to both the heating assembly and the temperature measuring assembly. The first electrical connection assembly 15 is used to connect to and establish an electrical connection with the second electrical connection assembly 24 of the support device 20. When the support device 20 is separated from the corresponding shelf 12, the first electrical connection assembly 15 disengages from the second electrical connection assembly 24, and the electrical connection is broken.

[0056] The electrical control device is a control component used to control the operation of the battery cell baking equipment 10. A first electrical connection assembly 15 is disposed on the shelf 12, and a second electrical connection assembly 24 is disposed on the support device 20. When the support device 20 is placed on the shelf 12, the first electrical connection assembly 15 and the second electrical connection assembly 24 come into contact with each other and establish an electrical connection, thereby achieving electrical communication between the electrical control device and the support device 20. When the support device 20 is removed from the shelf 12 by the handling device 13, the first electrical connection assembly 15 and the second electrical connection assembly 24 disengage, and the electrical connection is broken.

[0057] A heating element is mounted on the support device 20 to heat the battery cell 30 on the support device 20. A temperature sensing element is mounted on the support device 20 to detect the temperature of the battery cell 30 or the support device 20. The electronic control device supplies power to the heating element through the first electrical connection component 15 and the second electrical connection component 24, and acquires temperature signals through the temperature sensing element to monitor and adjust the baking temperature.

[0058] In this embodiment, a first electrical connection component 15 and a second electrical connection component 24 are respectively provided on the shelf 12 and the support device 20 to cooperate with each other. When the support device 20 is placed on the shelf 12, the circuit is automatically connected and when the support device 20 is removed, the circuit is automatically disconnected. This helps to improve the convenience of operation. Secondly, each support device 20 is independently powered and temperature measured, which makes it easy to independently monitor and adjust the baking temperature of each layer of battery cell 30, which helps to improve the uniformity and control accuracy of the baking temperature.

[0059] In some embodiments, please refer to Figure 2 and Figure 5 The electronic control device includes a power supply module and a control module. The first electrical connection assembly 15 includes a first electrical connector 151 and a second electrical connector 152. The first electrical connector 151 is electrically connected to the power supply module, and the second electrical connector 152 is electrically connected to the control module. The second electrical connection assembly 24 includes a third electrical connector 241 and a fourth electrical connector 242; the third electrical connector 241 is electrically connected to the heating assembly, and the fourth electrical connector 242 is electrically connected to the temperature measuring assembly. The first electrical connector 151 is used for electrical connection with the third electrical connector 241, and the second electrical connector 152 is used for electrical connection with the fourth electrical connector 242.

[0060] The power supply module provides power to the carrier device 20, such as powering the heating components on the carrier device 20. The control module is used for signal transmission with the carrier device 20, such as receiving temperature signals from the temperature sensing components on the carrier device 20 and controlling the power of the heating components.

[0061] The first electrical connector 151 is responsible for transmitting power, and the second electrical connector 152 is responsible for transmitting signals. When the support device 20 is placed on the shelf 12, the first electrical connector 151 contacts the third electrical connector 241 and establishes a power transmission path, and the second electrical connector 152 contacts the fourth electrical connector 242 and establishes a signal transmission path. When the support device 20 is removed, the first electrical connector 151 is disconnected from the third electrical connector 241, and the second electrical connector 152 is disconnected from the fourth electrical connector 242, thus breaking the power transmission path and the signal transmission path.

[0062] In this embodiment, power transmission and signal transmission are set separately and transmitted through independent electrical connectors, which can reduce the interference of power transmission on signal transmission, thereby improving the stability and reliability of signal transmission. Secondly, the first electrical connector 151 and the third electrical connector 241, and the second electrical connector 152 and the fourth electrical connector 242 are connected synchronously when the carrier device 20 is placed in place and disconnected synchronously when it is removed, which can improve the convenience of use.

[0063] In some embodiments, please refer to Figure 4The shelf 12 includes two self-feeding ports 112 extending along the depth direction of the furnace body 11, the depth direction being perpendicular to a first direction. The two shelf members 121 are arranged opposite to each other and spaced apart to define a joint space 120. One shelf member 121 is provided with a first electrical connector 151, and the other shelf member 121 is provided with a second electrical connector 152.

[0064] The support member 121 is the main supporting component of the support frame 12, and two support members 121 are arranged opposite to each other. The support member 121 extends from the material receiving port 112 along the depth direction of the furnace body 11, as shown in the depth direction. Figure 1 As shown in Figure y; the two sides of the supporting device 20 rest on two supports 121 respectively. The space between the two supports 121 is the engagement space 120, into which the material handling mechanism 133 of the conveying device 13 extends. The first electrical connector 151 and the second electrical connector 152 are respectively disposed on the two supports 121, corresponding to the second electrical connection assemblies 24 on both sides of the supporting device 20.

[0065] In this embodiment, by setting two supports 121 opposite to each other and spaced apart, the support structure of the bearing device 20 is defined, and the engagement space 120 for the conveying device 13 to extend into is naturally defined. The first electrical connector 151 and the second electrical connector 152 are respectively set on the two supports 121, so that the electrical connection and the signal connection are physically separated, which is beneficial to further improve the stability and reliability of signal transmission.

[0066] In some embodiments, please refer to Figure 4 Each support member 121 includes a mounting plate 121a and a plurality of support blocks 121b mounted on the mounting plate 121a. The plurality of support blocks 121b are arranged at intervals along the length of the mounting plate 121a to support the bearing device 20. A first electrical connector 151 and a second electrical connector 152 are respectively mounted on the mounting plate 121a of the corresponding support member 121, and are both located between two adjacent support blocks 121b.

[0067] Mounting plate 121a is a plate-shaped structure extending along the depth direction of furnace body 11. Multiple support blocks 121b are mounted on mounting plate 121a and arranged at intervals along its length. For example, the depth direction is as follows: Figure 1 As shown in y. The number of support blocks 121b can be two, three, four or more. The two side edges of the bearing device 20 rest on the support blocks 121b of the two side supports 121 respectively. The first electrical connector 151 and the second electrical connector 152 are mounted on the mounting plate 121a and are located between two adjacent support blocks 121b.

[0068] In this embodiment, by arranging the support blocks 121b at intervals, space is reserved for the installation of the first electrical connector 151 and the second electrical connector 152 while supporting the bearing device 20. Positioning the first electrical connector 151 and the second electrical connector 152 between adjacent support blocks 121b makes the electrical connectors more concealed, less susceptible to external impacts, and helps to improve the service life of the electrical connectors.

[0069] In some embodiments, please refer to Figure 2 and Figure 5 The first electrical connector 151 is a probe mechanism 150, and the third electrical connector 241 is a probe plate 240; the second electrical connector 152 is a probe mechanism 150, and the fourth electrical connector 242 is a probe plate 240; the probe mechanism 150 includes a plurality of probes 150a, and the probe plate 240 has a plurality of contact pads 240a, and the contact pads 240a are arranged in a one-to-one correspondence with the probes 150a.

[0070] The probe mechanism 150 includes a base and a plurality of probes 150a disposed on the base. Each probe 150a is an elastic conductive contact, comprising a needle tube, a spring, and a needle tip. The needle tip is retractably disposed within the needle tube. The spring is disposed within the needle tube and abuts against the bottom of the needle tube. The spring provides elastic force to the needle tip, causing it to tend to extend outwards. Both the needle tube and the needle tip are made of conductive material. The needle tube is electrically connected to a corresponding power module or control module via a wire.

[0071] The probe board 240 is a circuit board structure with contact pads 240a. The probe board 240 includes an insulating substrate and a conductive circuit layer on the surface of the insulating substrate. The insulating substrate is made of insulating material, and the conductive circuit layer is formed on the insulating substrate through etching or printing processes. The conductive circuit layer forms multiple contact pads 240a on the surface of the probe board 240, and the number and position of the contact pads 240a correspond one-to-one with the number and position of the probes 150a. The shape of the contact pads 240a can be circular, square, or rectangular, and the size of the contact pads 240a is adapted to the diameter of the probe tip of the probe 150a. The contact pads 240a are electrically connected to the corresponding heating component or temperature measuring component through the conductive circuit layer.

[0072] When the support device 20 is placed on the corresponding shelf 12, the probe 150a on the first electrical connector 151 abuts against the corresponding contact pad 240a on the probe plate 240 of the third electrical connector 241, and the probe 150a on the second electrical connector 152 abuts against the corresponding contact pad 240a on the probe plate 240 of the fourth electrical connector 242. The tip of the probe 150a is pressed against the surface of the contact pad 240a under the elastic force of the spring, forming a surface contact or point contact between the tip and the contact pad 240a, thereby achieving electrical conductivity. The spring provides continuous elastic force, which can improve the connection reliability of the first electrical connection assembly 15 and the second electrical connection assembly 24.

[0073] When the carrier device 20 is lifted vertically upward by the transport device 13 and separated from the shelf 12, the tip of the probe 150a disengages vertically from the contact pad 240a on the probe plate 240, and the electrical connection is broken. When the carrier device 20 is placed back on the shelf 12, the tip of the probe 150a re-engages with the contact pad 240a and establishes an electrical connection. That is, the connection is switched on and off by the lifting action of the carrier device 20, which improves the ease of use.

[0074] This embodiment uses probe 150a and probe plate 240 together, which improves the connection reliability of the first electrical connection component 15 and the second electrical connection component 24 and enhances the ease of use.

[0075] In some embodiments, please refer to Figure 3 and Figure 4 The shelf 12 is provided with a first limiting part 122, which is used to cooperate with the second limiting part of the bearing device 20 to restrict the movement of the bearing device 20 in the horizontal direction.

[0076] The first limiting part 122 and the second limiting part are mutually cooperating limiting structures, such as a protrusion and a groove, a stop and a slot, etc. When the bearing device 20 is placed on the shelf 12, the first limiting part 122 and the second limiting part cooperate to fix the position of the bearing device 20 in the horizontal direction.

[0077] In this embodiment, by setting mutually cooperating limiting parts, the supporting device 20 can be limited to a predetermined position on the shelf 12, which can reduce the accidental displacement of the supporting device 20 during the baking process.

[0078] Furthermore, after the carrier device 20 carries the battery cell 30 and rests on the shelf 12, the first electrical connector 151 (such as probe 150a) and the third electrical connector 241 (such as contact pad 240a on probe plate 240) need to maintain alignment accuracy. By providing a first limiting part 122 and a second limiting part that cooperate with each other, the carrier device 20 can be limited in the horizontal direction when it is placed on the shelf 12, so that the position of the carrier device 20 relative to the shelf 12 is fixed, which helps to improve the alignment accuracy and contact reliability between probe 150a and contact pad 240a.

[0079] In some embodiments, please refer to Figure 3 and Figure 5 The first limiting part 122 is a limiting guide post. The second limiting part is a limiting guide hole. The side of the shelf 12 that supports the bearing device 20 is a support surface. The limiting guide post protrudes from the support surface and can be inserted into the limiting guide hole to guide the bearing device 20 to move to a predetermined position when the bearing device 20 is placed on the shelf 12.

[0080] A limiting guide post is fixedly mounted on the shelf 12 and generally protrudes upward from the support surface of the shelf 12. A limiting guide hole is opened at the bottom of the bearing device 20, and the position of the limiting guide hole corresponds to the position of the limiting guide post. The shape and size of the limiting guide hole are adapted to the limiting guide post. When the bearing device 20 is placed on the shelf 12, the limiting guide post extends into the corresponding limiting guide hole. In addition, through the cooperation between the limiting guide post and the hole wall of the limiting guide hole, the horizontal movement of the bearing device 20 is restricted, so that the position of the bearing device 20 relative to the shelf 12 is fixed.

[0081] The number of limiting guide posts and limiting guide holes can be one or more. When there are multiple limiting guide posts and limiting guide holes, multiple limiting guide posts are set one-to-one with multiple limiting guide holes, and multiple limiting guide posts extend into the corresponding limiting guide holes simultaneously to guide and correct the horizontal position of the bearing device 20. Multiple limiting guide posts can be arranged at intervals along the circumference of the shelf 12. For example, a limiting guide post can be set at each of the four corners of the shelf 12, and correspondingly, four limiting guide holes are opened at the bottom of the bearing device 20 at the corresponding positions.

[0082] In this embodiment, by setting limiting guide posts and limiting guide holes, the bearing device 20 is positioned and constrained in the horizontal direction when placed on the shelf 12, which helps to maintain the alignment accuracy and electrical connection reliability between the probe 150a and the contact pad 240a on the probe plate 240.

[0083] In some embodiments, please refer to Figure 4The conveying device 13 includes a robotic arm 131 and a material handling mechanism 133 disposed on the robotic arm 131. The material handling mechanism 133 is used to engage with the carrying device 20. The robotic arm 131 is used to drive the material handling mechanism 133 to extend into or out of the baking cavity 111 through the material handling port 112.

[0084] The robotic arm 131 is a multi-axis motion mechanism capable of multi-degree-of-freedom movement in three-dimensional space; for example, a multi-axis walking robot can be used. The material handling mechanism 133 is installed at the execution end (i.e., the end effector) of the robotic arm 131 and is used to engage with the carrier device 20 (e.g., lifting, clamping, etc.). The robotic arm 131 drives the material handling mechanism 133 to move, causing it to extend through the material handling port 112 into the target position within the baking cavity 111, engage with the carrier device 20, and then remove the carrier device 20.

[0085] This embodiment uses a robotic arm 131 to drive the material handling mechanism 133, which can adapt to the handling requirements of the bearing device 20 with different heights and positions, further improving the flexibility of the sampling inspection of the battery cell 30.

[0086] In some embodiments, please refer to Figure 6 The material handling mechanism 133 includes a connecting plate 133a and at least two side-by-side material handling arms 133b. The connecting plate 133a is connected to the actuating end of the robotic arm 131. The at least two side-by-side material handling arms 133b are mounted on the connecting plate 133a. The material handling arms 133b are used to lift the carrier device 20 when extended into the baking cavity 111. The material handling arms 133b are provided with a first engagement portion 133c, which is used to cooperate with a second engagement portion 25 of the carrier device 20 to restrict the movement of the carrier device 20 on the material handling arms 133b.

[0087] The connecting plate 133a serves as a transitional component connecting the robotic arm 131 and the picking arm 133b. At least two picking arms 133b are arranged side-by-side, forming a fork-like structure. The picking arms 133b can extend under the carrying device 20 (e.g., into the engagement space 120) and then lift the carrying device 20. A first engagement portion 133c is provided on the picking arm 133b, and a second engagement portion 25 is provided on the carrying device 20. The two cooperate with each other to restrict the horizontal movement of the carrying device 20 on the picking arm 133b after it is lifted, thereby reducing the risk of the carrying device 20 slipping during handling.

[0088] This embodiment employs a forklift-type material handling structure with side-by-side picking arms 133b, which can stably support the carrying device 20. By providing a first joint 133c and a second joint 25 that cooperate with each other, the carrying device 20 is confined to the picking arms 133b during handling, which can reduce the risk of the carrying device 20 slipping during movement.

[0089] In some embodiments, please refer to Figures 4 to 7 The support device 20 includes a support base 21 and a plurality of brackets 22 disposed on the support base 21. The support base 21 is detachably disposed from the shelf 12. The plurality of brackets 22 are arranged side by side on the support base 21, and each bracket 22 is detachably connected to the support base 21. Each bracket 22 is used to support at least one battery cell 30.

[0090] The support base 21 is the main frame structure of the support device 20, used to cooperate with the shelf 12, for example, by resting on the support block 121b of the shelf 12. Multiple brackets 22 are arranged side-by-side on the support base 21, each bracket 22 for carrying the battery cell 30. The brackets 22 and the support base 21 are separable. The brackets 22 and the support base 21 can be detachably connected, for example, by a snap-fit ​​mechanism; alternatively, the brackets 22 can be mounted on the support base 21, for example, the support base 21 has a groove in which at least a portion of the bracket 22 is accommodated. This allows the brackets 22 to be individually removed from the support base 21. Thus, when a battery cell 30 on a particular bracket 22 needs to be sampled for inspection, the entire support device 20 can be removed first, then the target bracket 22 can be removed from the support base 21, and then the battery cell 30 on that bracket 22 can be subjected to moisture testing.

[0091] This embodiment achieves modular management of the battery cells 30 by setting multiple detachable brackets 22 on the support substrate 21, with each bracket 22 independently carrying a battery cell 30. When sampling inspection is required, removing the target bracket 22 does not require moving the battery cells 30 on other brackets 22, thus reducing the impact of sampling inspection on non-target battery cells 30. Furthermore, the detachable design of the brackets 22 facilitates cleaning, maintenance, and replacement of the brackets 22.

[0092] In some embodiments, please refer to Figure 8 The bracket 22 includes a tray 221 and a limiting block 222. The tray 221 is separable from the supporting base 21. The limiting block 222 is disposed on the tray 221, and the limiting block 222 and the tray 221 define a placement slot. The large surface of the battery cell 30 is disposed opposite to the tray 221. Each placement slot is used to place at least two battery cells 30. At least two battery cells 30 are arranged sequentially along a direction perpendicular to the tray 221, and adjacent battery cells 30 are separated by a partition 23.

[0093] The tray 221 serves as the bottom support plate for the bracket 22, supporting the battery cell 30. A limiting block 222 is positioned at the edge or center of the tray 221, defining a placement groove together with the tray 221. The battery cell 30 is placed on the tray 221 with its largest surface facing down, meaning the planar sidewall of the battery cell 30 is opposite to the tray 221. The battery cell 30 is a bare, stacked battery cell; the fact that its largest surface is opposite the tray 221 reduces issues such as electrode misalignment or bending. The largest surface refers to the side of the battery cell 30 with the largest area.

[0094] At least two battery cells 30 can be placed in each slot, and these battery cells 30 are stacked sequentially along the direction of the vertical support plate 221 (i.e., the thickness direction). Adjacent battery cells 30 are separated by a partition 23. The partition 23 serves two purposes: firstly, it isolates the adjacent battery cells 30 and reduces contact between them; secondly, it transfers heat and improves the uniformity of baking.

[0095] In this embodiment, by placing a slot on the bracket 22 and setting the large surface of the battery cell 30 opposite to the tray 221, problems such as misalignment / bending between electrodes can be reduced. The partition 23 separates the stacked battery cells 30, which not only achieves isolation between the battery cells 30, but also facilitates the uniform transfer of heat and helps to improve the consistency of the baking effect of the battery cells 30.

[0096] In some embodiments, please refer to Figure 9 The battery cell baking equipment 10 also includes a feeding device 17. The feeding device 17 is used to remove the battery cell 30 from the tray 22.

[0097] The feeding device 17 is a mechanism for realizing automatic feeding. After the carrier device 20 is removed from the furnace body 11 by the conveying device 13, the feeding device 17 can further separate and remove the bracket 22 from the carrier base 21, and remove the battery cell 30 from the bracket 22, realizing a fully automated sampling and feeding process.

[0098] This embodiment achieves automated operation from removal from the carrier device 20 to separation from the bracket 22 and then removal of the battery cell 30 by setting up the unloading device 17, which helps to improve the sampling efficiency of the battery cell 30; secondly, it reduces manual intervention and helps to reduce the risk of damage to the battery cell 30 caused by human operation.

[0099] In some embodiments, please refer to Figures 7 to 9 The feeding device 17 includes a hook 171 and an adsorption part 172. The hook 171 is used to extend into the bracket 22 to lift the battery cell 30 of the bracket 22. The adsorption part 172 is used to adsorb onto the upper surface of the battery cell 30 lifted by the hook 171.

[0100] The hook 171 is a retractable or swingable claw-shaped structure that can extend into the bracket 22 and lift the battery cell 30 from below. For example, the hook 171 is an L-shaped claw or other shaped claw. The suction part 172 is a vacuum suction cup or other suction element used to suction the upper surface of the battery cell 30 from above. The hook 171 and the suction part 172 work together, with the hook 171 providing support from below and the suction part 172 providing suction from above, together removing the battery cell 30 from the bracket 22.

[0101] In this embodiment, the hook 171 and the adsorption part 172 work together to achieve stable picking and placing of the battery cell 30. The hook 171 lifts the battery cell 30 from below to provide the main support, while the adsorption part 172 adsorbs the battery cell 30 from above. The synergistic effect of the two can improve the stability of picking and placing the battery cell 30.

[0102] In some embodiments, please refer to Figures 7 to 9 The tray 221 is provided with a first clearance space 221a, and the hook 171 can extend into the first clearance space 221a to lift the battery cell 30 of the tray 221. And / or, the partition 23 is provided with a second clearance space 23a, and the hook 171 can extend into the second clearance space 23a to lift the battery cell 30 of the partition 23.

[0103] The first clearance space 221a is an opening or groove provided on the tray 221 for the hook 171 to extend into. When the hook 171 extends into the first clearance space 221a, the battery cell 30 placed on the tray 221 can be lifted from below. The second clearance space 23a is an opening or groove provided on the partition 23 for the hook 171 to extend into. When the hook 171 extends into the second clearance space 23a, the battery cell 30 placed on the partition 23 can be lifted from below.

[0104] This embodiment provides an access channel for the hook 171 by providing clearance space on the tray 221 and / or partition 23. This allows the hook 171 to directly reach the bottom of the battery cell 30 without having to go around the edge of the tray 221 or partition 23, thereby reducing the travel and range of motion of the hook 171 and reducing the risk of collision or interference with the surrounding structure during the picking and placing process. This helps to improve the efficiency and reliability of the unloading operation.

[0105] In some embodiments, see Figures 1 to 9 This application provides a cell baking apparatus 10, suitable for baking and drying solid-state battery cells 30. The cell baking apparatus 10 includes a furnace body 11; as shown... Figure 1 As shown, the width direction of the furnace body 11 is x, the depth direction of the furnace body 11 is y, and the height direction of the furnace body 11 is z; x, y, and z are arranged perpendicularly to each other.

[0106] Multiple shelves 12 are arranged vertically inside the furnace body 11, and each shelf 12 holds a supporting device 20. Multiple brackets 22 are arranged side-by-side on the supporting base 21 of each supporting device 20. At least two battery cells 30 are stacked in the placement slot of each bracket 22, and adjacent battery cells 30 are separated by partitions 23. A heating component and a temperature measuring component are arranged on the supporting base 21, and are electrically connected to a first electrical connection component 15 on the shelf 12 via a second electrical connection component 24; the first electrical connection component 15 is connected to an electrical control device.

[0107] When a specific layer of battery cell 30 needs to be sampled for inspection, the oven door opens, and the robotic arm 131 of the conveying device 13 drives the material handling mechanism 133 to extend into the baking chamber 111 through the material handling port 112. The material handling arm 133b extends into the engagement space 120 below the target carrier 20, lifts the carrier 20 upward to separate it from the shelf 12, and then moves the carrier 20 out of the material handling port 112 horizontally. After the carrier 20 is removed, the first electrical connection assembly 15 and the second electrical connection assembly 24 are automatically disconnected.

[0108] After the carrier device 20 is removed, the hook 171 of the unloading device 17 extends into the clearance space of the target bracket 22, lifting the battery cell 30 from below. The adsorption part 172 adsorbs the upper surface of the battery cell 30 from above, together removing the battery cell 30 from the bracket 22 for subsequent moisture content testing. After sampling is completed, the carrier device 20 can be returned to the original shelf 12 for continued baking.

[0109] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not 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.
