Description

Technical Field

[0001] The present application relates to the field of battery technology, and in particular to a battery drying fixture, device, system and battery production line. Background Art

[0002] During the production of batteries, some parts of the batteries contain moisture, and the batteries need to be dried to reduce or even eliminate the moisture in the batteries. For example, after the electrode assembly in the battery is installed in the housing, the electrode assembly needs to be dried. In the related art, during the drying process of the battery, multiple batteries are often dried at the same time, but the drying rates of batteries at different positions are different, which affects the drying effect of the battery. Summary of the invention

[0003] The present application provides a battery drying fixture, a device, a system and a battery production line, which can achieve uniform heating of all batteries carried in the battery drying fixture.

[0004] The first aspect of the present application provides a battery drying fixture, which includes: a substrate, a limiting structure, a heating element and a heating circuit. The substrate is made of a heat-conducting material; the limiting structure is arranged on the substrate, and the limiting structure is formed with a plurality of battery cell profiling holes, and the battery cell profiling holes are used to accommodate and limit a single battery cell; the heating element is arranged on the side of the substrate opposite to the limiting structure, and the heating element includes an internal hot zone and a surrounding hot zone, the internal hot zone corresponds to the battery cell profiling holes close to the center of the substrate, and the surrounding hot zone corresponds to the battery cell profiling holes close to the edge of the substrate, and the internal hot zone and the surrounding hot zone have different heating powers; the internal hot zone and the surrounding hot zone are electrically connected to a heating circuit respectively, and the heating circuit is used to be electrically connected to a power supply to apply electrical energy to the internal hot zone and the surrounding hot zone respectively.

[0005] The battery drying fixture provided by the present application can transfer heat at a faster speed by using the substrate because the substrate is made of a heat-conducting material. A limiting structure having a plurality of cell-profiled holes is provided on the substrate, and the cell can be accommodated in the battery drying fixture through the cell-profiled holes. A heating element is provided on the substrate, and the heating element can be used to provide heat to the substrate and the limiting structure, so as to heat the cell in the cell-profiled hole. At the same time, the heating element is set to include two structures that can independently control the heating power, including an internal hot zone and a surrounding hot zone, and the internal hot zone and the surrounding hot zone can be controlled separately according to the amount of heat required in different areas of the battery drying fixture, so that the central area of ​​the battery drying fixture and the surrounding edge areas can be subjected to the same or nearly the same heat, and the cells in the cell-profiled holes at different positions in the battery drying fixture can be subjected to the same or nearly the same heat, so that uniform heating of all cells carried in the battery drying fixture can be achieved, so that all cells in the battery drying fixture have the same or nearly the same drying rate.

[0006] In a possible implementation of the present application, the surrounding thermal zone is arranged around the internal thermal zone.

[0007] In the technical solution of the present application, since the surrounding heat zone is set as a structure surrounding the internal heat zone, less heat can be provided to the central area of ​​the substrate through the internal heat zone, while more heat can be provided to the edges of the substrate through the surrounding heat zone. Compared with a structure in which the heating element is set as an integral part, when the substrate is heated, the temperature of the central area of ​​the substrate is higher than that of the edge area due to heat accumulation. In the embodiment of the present application, the heat provided to the central area of ​​the substrate can be reduced through the internal heat zone, so that the heat received by each area on the substrate can be nearly the same.

[0008] In a possible implementation of the present application, the internal thermal zone includes at least two sub-thermal zones, which are arranged adjacent to each other in sequence, and the sub-thermal zone far from the center of the substrate surrounds the sub-thermal zone close to the center of the substrate.

[0009] In the technical solution of the present application, since the internal heat zone includes at least two sub-heat zones, the heat provided to the annular area corresponding to each sub-heat zone on the substrate can be independently controlled, so that the heat of each annular area on the substrate can be accurately controlled, which is beneficial to reducing the situation where the temperature of the area closer to the center of the substrate is higher than the temperature of other areas on the substrate.

[0010] In a possible implementation of the present application, the internal thermal zone includes a first sub-thermal zone and a second sub-thermal zone, the first sub-thermal zone is close to the center of the substrate, and the second sub-thermal zone is arranged around the first sub-thermal zone.

[0011] In the technical solution of the present application, since the internal heat zone includes the first sub-heat zone and the second sub-heat zone, the heating amounts of the areas on the substrate corresponding to the first sub-heat zone and the second sub-heat zone respectively can be independently controlled, which is beneficial to reducing the situation where the temperature of the area corresponding to the first sub-heat zone on the substrate is higher or lower than the temperature of the area corresponding to the second sub-heat zone.

[0012] In a possible implementation of the present application, the sub-heat zone close to the center of the substrate includes at least two internal sub-heat zones, and the at least two internal sub-heat zones are distributed in a rectangular array.

[0013] In the technical solution of the present application, since the sub-heat zone near the center of the substrate is set as at least two internal sub-heat zones distributed in a rectangular array, the area near the center of the substrate can be divided into more heating zones with smaller areas, so that the temperature of the area near the center of the substrate can be made consistent or substantially consistent with the temperature of the edge of the substrate by independently controlling the heating power of each internal sub-heat zone.

[0014] In a possible implementation of the present application, the internal heat zone includes at least four internal sub-heat zones, and the at least four internal sub-heat zones are distributed in a rectangular array.

[0015] In the technical solution of the present application, since the internal thermal zone includes at least four internal sub-thermal zones, and the at least four internal sub-thermal zones are distributed in a rectangular array, the heat received by the area on the substrate corresponding to the internal thermal zone can be more accurately controlled, so that the heat received by different areas in the area on the substrate corresponding to the internal thermal zone can be consistent or nearly consistent with the heat required by the battery cell.

[0016] In a possible implementation of the present application, the heating power of the inner heat zone is smaller than the heating power of the surrounding heat zones.

[0017] In the technical solution of the present application, since the heating power of the internal hot zone of the heating element is smaller than the heating power of the surrounding hot zone, the heat received by the central area of ​​the substrate can be less than the heat received by the edge area of ​​the substrate. Since the heat in the edge area of ​​the substrate is dissipated faster than the heat in the central area of ​​the substrate, the temperature of the central area and the edge area on the substrate can be made basically the same, and thus the temperature of the battery cells located at different positions in the battery drying fixture can be made basically the same.

[0018] In a possible implementation of the present application, the limiting structure includes a guide block and a shaping block, the shaping block is arranged on the substrate, and the guide block is located on the side of the shaping block away from the substrate; the battery cell shaping hole includes a guide section and a limiting section, the limiting section is arranged on the shaping block, and the guide section is arranged on the guide block, and the diameter of at least part of the guide section is larger than the diameter of the limiting section.

[0019] In the technical solution of the present application, since the battery cell profiling hole includes a guide section and a limiting section, during the process of placing the battery cell into the battery cell profiling hole, the diameter of the guide section is larger than the diameter of the limiting section, that is, the diameter of the guide section is larger than the diameter of the battery cell, thereby making it easier for the battery cell to enter the battery cell profiling hole, which is beneficial to reducing the requirements for the movement accuracy of the equipment or device for transporting the battery cell.

[0020] In a possible implementation of the present application, the battery drying fixture further includes a flexible protective member, which fits in the battery cell contour hole, and the hardness of the flexible protective member is less than the hardness of the battery cell.

[0021] In the technical solution of the present application, since a flexible protective member is provided in the battery cell profiling hole, the battery cell can be brought into contact with the flexible protective member and move relative to the flexible protective member during the process of placing the battery cell into the battery cell profiling hole or taking the battery cell out of the battery cell profiling hole. Since the hardness of the flexible protective member is less than the hardness of the battery cell, it is beneficial to reduce the risk of scratching the battery cell by the battery drying clamp.

[0022] In a possible implementation of the present application, the battery drying fixture further includes a reflector, which surrounds the limiting structure. Along the overlapping direction of the limiting structure and the substrate, the height of the reflector is greater than or equal to the height of the limiting structure.

[0023] In the technical solution of the present application, since a reflective member is arranged around the limiting structure, the reflective member can be used to reflect the heat radiated by the limiting structure to the limiting structure, thereby helping to slow down the rate at which heat from the battery drying clamp is dissipated into the surrounding environment and helping to improve energy utilization.

[0024] In a possible implementation of the present application, the battery drying fixture further includes a first movable component, the first movable component is disposed on the substrate, the first movable component matches the movable fixture, and the battery drying fixture can be moved on the movable fixture through the first movable component.

[0025] In the technical solution of the present application, since a first movable assembly is provided on the substrate, the battery drying fixture can be easily moved relative to the movable fixture through the first movable assembly, which is beneficial to reducing the wear of the battery drying fixture when it moves relative to the movable fixture.

[0026] In a possible implementation of the present application, the battery drying clamp also includes a first locking component, which is arranged on the substrate. When the battery drying clamp is placed on the mobile clamp, the first locking component can move relative to the substrate and abut against the mobile clamp to limit the movement of the battery drying clamp relative to the mobile clamp.

[0027] In the technical solution of the present application, since a first locking component is provided on the battery drying clamp, the first locking component can be used to limit the movement of the battery drying clamp relative to the movable clamp, so that after the battery drying clamp moves into place on the movable clamp, the battery drying clamp can be in a fixed position relative to the movable clamp, so as to facilitate the accurate placement of the battery cell into the battery cell contoured hole, or the removal of the battery from the battery cell contoured hole.

[0031] In the technical solution of the present application, since a first guide component matching the first movable component in the battery drying fixture is provided in the carrying mechanism, the battery drying fixture can be moved relative to the movable fixture on the carrying mechanism through the first movable component and the first guide component, thereby facilitating the battery drying fixture to enter the movable fixture or to exit the battery drying fixture from the movable fixture.

[0032] In a possible implementation of the present application, the battery drying device also includes a first locking component and a first positioning member matching the first locking component, the first locking component is arranged in one of the substrate and the carrier, the first positioning member is arranged in the other of the substrate and the carrier, and the first locking component cooperates with the first positioning member to limit the movement of the battery drying clamp relative to the carrier.

[0033] In the technical solution of the present application, since matching first locking components and first positioning members are respectively provided on the base plate and the carrier frame, after the battery drying clamp moves into place on the mobile clamp, the first locking component can be controlled to abut against the first positioning member, so that the battery drying clamp can be fixed to the mobile clamp through the first locking component and the first positioning member, thereby reducing the occurrence of unnecessary movement of the battery drying clamp relative to the mobile clamp.

[0034] In a possible implementation of the present application, the battery drying device also includes a detection member and a trigger member, the detection member is arranged in one of the substrate and the carrier, and the trigger member is arranged in the other of the substrate and the carrier; when the battery drying clamp moves relative to the carrier until the detection member abuts against the trigger member, the detection member can generate a control signal to control the movement of the first locking component.

[0035] In the technical solution of the present application, since matching detection components and trigger components are respectively provided on the substrate and the carrier frame, when the battery drying fixture moves into place on the mobile fixture, a control signal can be generated in time through the detection component so as to obtain the information that the battery drying fixture moves into place on the mobile fixture in time.

[0036] The third aspect of the present application provides a battery drying system, which includes: a disassembly tray device and the battery drying device provided in the second aspect. The disassembly tray device includes adjacent disassembly tools and parking tools; the parking tool matches the mobile fixture so that the mobile fixture can be movably carried on the parking tool; the disassembly tool includes at least two drawer mechanisms stacked on the disassembly tray frame at intervals, and the battery drying fixture can be movably carried on the drawer mechanism; the disassembly tool can move the battery drying fixture located on the drawer mechanism to the carrying mechanism, or move the battery drying fixture located on the carrying mechanism to the drawer mechanism.

[0037] The battery drying system provided by the present application includes the battery drying fixture provided above, and therefore, can achieve uniform heating of all the battery cells carried in the battery drying fixture, so that all the battery cells in the battery drying fixture have the same or nearly the same drying rate. In addition, adjacent disassembly tools and parking tools are provided in the disassembly tray device, so as to facilitate the assembly or disassembly of multiple battery drying fixtures on the mobile fixture.

[0038] In a possible implementation of the present application, the drawer mechanism includes a second guide component, which corresponds to the first guide component and matches the first movable component of the battery drying fixture; the disassembly tool also includes a second locking component arranged on the disassembly disk frame, and the battery drying fixture also has a second positioning member matching the second locking component, and when the battery drying fixture moves from the first guide component to the second guide component through the first movable component, the second locking component cooperates with the second positioning member to limit the movement of the battery drying fixture relative to the disassembly tool.

[0039] In the technical solution of the present application, since the drawer mechanism and the mobile fixture respectively include the corresponding second guide assembly and first guide assembly, it is convenient to make the battery drying fixture move along the first guide assembly and the second guide assembly through the first mobile assembly, so as to realize the movement of the battery drying fixture between the disassembly tooling and the mobile fixture. And the movement of the battery drying fixture relative to the disassembly tooling can be restricted by the cooperation of the second locking assembly and the second positioning member.

[0040] In a possible implementation of the present application, the disassembly tool also includes a push-pull mechanism, which is slidably arranged on the disassembly disk frame and corresponds to the drawer mechanism.

[0056] At present, new energy batteries are increasingly used in life and industry. New energy batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but are also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as aerospace and other fields. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding.

[0057] During the battery production process, some parts will contain moisture. For example, during the production of electrode assemblies, the electrode assemblies will contain moisture. In the subsequent production process, the electrode assemblies need to be dried to improve the production efficiency of the battery.

[0058] The electrode assembly includes a positive electrode, a negative electrode and a separator, and the separator is arranged between the negative electrode and the positive electrode. During the charge and discharge process of the battery cell, active ions (such as lithium ions) are inserted and removed back and forth between the positive electrode and the negative electrode. The separator is arranged between the positive electrode and the negative electrode, which can prevent the positive and negative electrodes from short-circuiting, and at the same time allow the active ions to pass through. The positive electrode can be a positive electrode sheet, and the positive electrode sheet can include a positive electrode current collector and a positive electrode active material arranged on at least one surface of the positive electrode current collector. The positive electrode active material can include at least one of the following materials: lithium-containing phosphate, lithium transition metal oxide and their respective modified compounds. The negative electrode can be a negative electrode sheet, and the negative electrode sheet can include a negative electrode current collector and a negative electrode active material arranged on at least one surface of the negative electrode current collector. The negative electrode active material can include at least one of the following materials: artificial graphite, natural graphite, soft carbon, hard carbon, silicon-based material, tin-based material and lithium titanate. Some of the positive electrode active material and the negative electrode active material are in slurry form, and the slurry-like active material containing water is coated on the current collector to obtain a pole sheet.

[0059] After the electrode assembly is placed in the battery casing and before the battery is injected or soaked, the electrode assembly in the battery casing needs to be dried to the required degree. The battery needs to be dried. For example, for cylindrical batteries, square shell batteries, etc., multiple batteries can be placed in an oven and heated to evaporate the water in the batteries quickly. In the related art, when multiple batteries are dried simultaneously using a drying device, the heat received by batteries at different positions in the drying device is often different, that is, multiple batteries cannot be heated evenly, which affects the drying effect of the batteries.

[0060] The present application provides a battery drying fixture that can evenly heat multiple battery cells in the battery drying fixture. Figure 1 , Figure 2 and Figure 3 , Figure 1 This is a schematic diagram of the structure of the battery drying fixture provided in this application. Figure 2 The exploded schematic diagram of the battery drying fixture provided for this application is Figure 3 Schematic diagram of the structure of the heating element in the battery drying fixture provided in this application Figure 1 . The battery drying fixture 1 includes: a substrate 11, a limiting structure 13, a heating element 12 and a heating circuit (not shown in the figure). Among them, the substrate 11 is made of a heat-conducting material; the limiting structure 13 is arranged on the substrate 11, and the limiting structure 13 is formed with a plurality of battery cell profiling holes 131, and the battery cell profiling holes 131 are used to accommodate and limit a single battery cell; the heating element 12 is arranged on the side of the substrate 11 opposite to the limiting structure 13, and the heating element 12 includes an internal hot zone 121 and a surrounding hot zone 122, the internal hot zone 121 corresponds to the battery cell profiling hole 131 close to the center of the substrate 11, and the surrounding hot zone 122 corresponds to the battery cell profiling hole 131 close to the edge of the substrate 11; the internal hot zone and the surrounding hot zone are respectively electrically connected to a heating circuit, and the heating circuit is used to be electrically connected to a power supply to apply electrical energy to the internal hot zone and the surrounding hot zone respectively.

[0061] In the present application embodiment, Figure 1 and Figure 2 As shown, the substrate 11 is used to set and carry other parts in the battery drying fixture 1 and to conduct heat. For example, the substrate 11 can be made of metal materials such as aluminum, aluminum alloy, copper, copper alloy, etc. with good thermal conductivity. The substrate 11 can be set as a flat plate structure.

[0062] In the embodiment of the present application, the limiting structure 13 is used to limit and accommodate the battery or parts in the battery to be dried. For example, the limiting structure 13 can be set according to the structure of the battery cell in the battery, so that the battery drying fixture 1 can be used to heat multiple battery cells to dry the battery cells at a faster speed.

[0063] Exemplarily, a plurality of cell profiling holes 131 matching the shape of the cell can be provided on the limiting structure 13. For example, when the cell is a cylindrical cell, the cell profiling hole 131 can be provided as a cylindrical hole, and when the cell is a square cell, the cell profiling hole 131 can be provided as a cubic hole. The limiting structure 13 can be attached to one side surface of the substrate 11, and the limiting structure 13 can be fixed to the substrate 11. Then, a single cell can be inserted into a cell profiling hole 131, and one end of the cell can be abutted against the substrate 11 to achieve the limiting of the cell.

[0064] In the embodiment of the present application, the heating element 12 is used to provide heat to the substrate 11 and the limiting structure 13, so as to heat the battery cell accommodated in the battery cell profiling hole 131. For example, the heating element 12 can be arranged on the surface of the substrate 11 opposite to the limiting structure 13, that is, the heating element 12 is located on the side surface of the substrate 11 away from the limiting structure 13. The heating element 12 can be a device that can be heated by electric energy, such as a graphene electric heating film, a polyimide electric heating film, and a silicone electric heating film.

[0065] For example, Figure 3 As shown, the heating element 12 can be configured to have a structure with at least two heating areas. For example, the heating element 12 is configured to have two structures capable of independently controlling the heating temperature, that is, the internal heat zone 121 of the heating element 12 independently heats the central area of ​​the substrate 11, and the surrounding heat zone 122 of the heating element 12 heats the surrounding edge areas of the substrate 11. The internal heat zone 121 and the surrounding heat zone 122 of the heating element 12 can use different heating devices, or can use the same heating device, but the heating devices are arranged in different densities in the internal heat zone 121 and the surrounding heat zone 122. For example, when the heating element 12 includes multiple heating wires, the density of the heating wires in the internal heat zone 121 can be made smaller than the density of the heating wires in the surrounding heat zone 122. The internal heat zone 121 and the surrounding heat zone 122 can have different heating powers, that is, the internal heat zone 121 and the surrounding heat zone 122 generate different amounts of heat in the same period of time. Correspondingly, different amounts of heat are provided to the central area on the substrate 11 and the edge areas around the substrate 11. This makes it easier to control the heat of the battery cell profiling holes 131 at different positions in the battery drying fixture 1.

[0066] In the embodiment of the present application, independent heating circuits may be provided for the internal hot zone 121 and the surrounding hot zone 122, respectively, so as to electrically connect the internal hot zone 121 and the surrounding hot zone 122 to the power supply through their respective heating circuits. For example, the heating circuit may include a wire and a controller, or the heating circuit may also include a wire.

[0067] For example, Figure 2As shown, the pressing member 191 can be used to press and fit the heating member 12 onto the substrate 11. A connector 16 can be provided for the heating member 12, and the connector 16 can be fixed to one end of the substrate 11, and each joint on the connector 16 is electrically connected to a heating circuit of a hot zone of the heating member 12, so that the heating circuit is electrically connected to the power supply through the connector 16. A wire groove 192 can also be provided on the side of the pressing member 191 away from the heating member 12, and the wire groove 192 is fixedly connected to the substrate 11, so as to form a space for accommodating the heating circuit between the pressing member 191 and the wire groove 192.

[0068] The battery drying fixture 1 provided in the embodiment of the present application can transfer heat at a faster speed by using the substrate 11 because the substrate 11 is made of a heat-conducting material. In addition, a limiting structure 13 having a plurality of battery cell profiling holes 131 is provided on the substrate 11, and the battery cell can be accommodated in the battery drying fixture 1 through the battery cell profiling holes 131. In addition, a heating element 12 is provided on the substrate 11, and the heating element 12 can be used to provide heat to the substrate 11 and the limiting structure 13, so as to heat the battery cell in the battery cell profiling hole 131. At the same time, the heating element 12 is configured to include two structures that can independently control the heating power, namely, an internal heat zone 121 and a surrounding heat zone 122. The internal heat zone 121 and the surrounding heat zone 122 can be controlled separately according to the amount of heat required by different areas in the battery drying fixture 1, so that the central area and the surrounding edge areas of the battery drying fixture 1 can receive the same or nearly the same amount of heat, and the battery cells in the battery cell profiling holes 131 located at different positions in the battery drying fixture 1 can receive the same or nearly the same amount of heat, so that uniform heating of all the battery cells carried in the battery drying fixture 1 can be achieved, so that all the battery cells in the battery drying fixture 1 have the same or nearly the same drying rate.

[0069] In some possible embodiments of the present application, Figure 3 As shown, the surrounding heat zone 122 is disposed around the inner heat zone 121 .

[0070] In the embodiment of the present application, the surrounding heat zone 122 in the heating element 12 can be set to an annular structure, and the surrounding heat zone 122 surrounds the internal heat zone 121. For example, when the substrate 11 is a rectangular structure, the internal heat zone 121 can be set to a rectangle similar to the rectangular substrate 11, and the surrounding heat zone 122 can be a rectangular ring. When the substrate 11 is a circular structure, the internal heat zone 121 can be set to a circle similar to the circular substrate 11, and the surrounding heat zone 122 can be a circular ring. In this way, the surrounding heat zone 122 can heat the surrounding edge areas of the substrate 11, and the internal heat zone 121 can heat the rectangular area near the center of the substrate 11.

[0071] In the above embodiment, since the surrounding heat zone 122 is set as a structure surrounding the internal heat zone 121, less heat can be provided to the central area of ​​the substrate 11 through the internal heat zone 121, and more heat can be provided to the edges of the substrate 11 through the surrounding heat zone 122. Compared with the structure in which the heating element 12 is set as an integral body, when the substrate 11 is heated, the temperature of the central area of ​​the substrate 11 is higher than that of the edge area due to heat accumulation. In the embodiment of the present application, the heat provided to the central area of ​​the substrate 11 can be reduced through the internal heat zone 121, so that the heat received by each area on the substrate 11 can be almost the same.

[0072] In some possible embodiments of the present application, refer to Figure 4 , Figure 4 Schematic diagram of the structure of the heating element in the battery drying fixture provided in this application Figure 2 The internal heat zone 121 includes at least two sub-heat zones, which are arranged adjacent to each other in sequence, and the sub-heat zone far from the center of the substrate 11 surrounds the sub-heat zone close to the center of the substrate 11 .

[0073] In the embodiment of the present application, the closer to the center area of ​​the substrate 11, the easier it is for heat to accumulate, and the temperature of the center area of ​​the substrate 11 is likely to be higher than the temperature of the surrounding area of ​​the substrate 11. Figure 4 As shown, the internal heat zone 121 of the heating element 12 can be configured as a structure of at least two sub-heat zones, and the heating power of each sub-heat zone can be independently controlled.

[0074] Exemplarily, the internal thermal zone 121 may be configured as three sub-thermal zones. One sub-thermal zone is located at the center of the substrate 11, another sub-thermal zone surrounds the sub-thermal zone located at the center of the substrate 11, and the third sub-thermal zone surrounds the other sub-thermal zone. Alternatively, the internal thermal zone 121 may be configured as four sub-thermal zones, five sub-thermal zones, etc., and the plurality of sub-thermal zones are sequentially arranged around the center of the substrate 11.

[0075] In the above embodiment, since the internal heat zone 121 includes at least two sub-heat zones, the heat provided by the annular area corresponding to each sub-heat zone on the substrate 11 can be independently controlled, so that the heat of each annular area on the substrate 11 can be accurately controlled, which is beneficial to reduce the situation where the temperature of the area on the substrate 11 closer to the center of the substrate 11 is higher than the temperature of other areas on the substrate 11.

[0076] In some possible embodiments of the present application, Figure 4 As shown, the internal thermal zone 121 includes a first sub-thermal zone 1211 and a second sub-thermal zone 1212 . The first sub-thermal zone 1211 is close to the center of the substrate 11 , and the second sub-thermal zone 1212 is disposed around the first sub-thermal zone 1211 .

[0077] In the embodiment of the present application, in order to achieve accurate control of the heat of different areas on the substrate 11, the control of the heating element 12 can be simplified at the same time. Figure 4 As shown, the internal heat zone 121 of the heating element 12 can be configured as a structure of a first sub-heat zone 1211 and a second sub-heat zone 1212, and the heating powers of the first sub-heat zone 1211 and the second sub-heat zone 1212 can be independently controlled.

[0078] For example, the first sub-hot zone 1211 can be set to a rectangle similar to the shape of the substrate 11, and the second sub-hot zone 1212 can be set to a ring structure. The first sub-hot zone 1211 is attached to the central area of ​​the substrate 11, and the second sub-hot zone 1212 surrounds the first sub-hot zone 1211.

[0079] In the above embodiment, since the internal heat zone 121 includes the first sub-heat zone 1211 and the second sub-heat zone 1212, the heating amounts of the areas on the substrate 11 corresponding to the first sub-heat zone 1211 and the second sub-heat zone 1212 respectively can be independently controlled, which helps to reduce the situation where the temperature of the area on the substrate 11 corresponding to the first sub-heat zone 1211 is higher or lower than the temperature of the area corresponding to the second sub-heat zone 1212.

[0080] In some possible embodiments of the present application, refer to Figure 5 , Figure 5 Schematic diagram of the structure of the heating element in the battery drying fixture provided in this application Figure 3 The sub-heat zone near the center of the substrate 11 includes at least two inner sub-heat zones, and the at least two inner sub-heat zones are distributed in a rectangular array.

[0081] In the present application embodiment, Figure 4 and Figure 5 As shown, the sub-heating zone in the center of the substrate 11 in the heating element can be set to a structure of multiple internal sub-heating zones distributed in a rectangular array. For example, two internal sub-heating zones can be set, and the two internal sub-heating zones can be distributed in parallel. Three internal sub-heating zones can also be set, and the three internal sub-heating zones can be arranged in sequence. Or, Figure 4 The first sub-heat zone 1211 in the embodiment is configured to include a structure of four inner sub-heat zones, and the four inner sub-heat zones may be distributed in a rectangular array of two rows and two columns.

[0082] In the above embodiment, since the sub-heat zone near the center of the substrate 11 is set as at least two internal sub-heat zones distributed in a rectangular array, the area near the center of the substrate 11 can be divided into more heating areas with smaller areas, so that the temperature of the area near the center of the substrate 11 can be consistent or substantially consistent with the temperature of the edge of the substrate 11 by independently controlling the heating power of each internal sub-heat zone.

[0083] In some possible embodiments of the present application, Figure 5 As shown, the internal thermal zone 121 includes at least four internal sub-thermal zones 1213, and the at least four internal sub-thermal zones 1213 are distributed in a rectangular array.

[0084] In the embodiment of the present application, the internal heat zone 121 can be configured to include at least four internal sub-heat zones 1213, and the at least four internal sub-heat zones 1213 are distributed in a rectangular array, wherein the heating power of each internal sub-heat zone 1213 can be independently controlled.

[0085] Exemplarily, the internal thermal zone 121 may be configured as four internal sub-thermal zones 1213, and the four internal sub-thermal zones 1213 may be distributed in a rectangular array of two rows and two columns. The internal thermal zone 121 may also be configured as six internal sub-thermal zones 1213, and the six internal sub-thermal zones 1213 may be distributed in a rectangular array of three rows and two columns. The internal thermal zone 121 may also be configured as eight internal sub-thermal zones 1213, and the eight internal sub-thermal zones 1213 may be distributed in a rectangular array of four rows and two columns.

[0086] In the above embodiment, since the internal thermal zone 121 includes at least four internal sub-thermal zones 1213, and the at least four internal sub-thermal zones 1213 are distributed in a rectangular array, the heat received by the area on the substrate 11 corresponding to the internal thermal zone 121 can be more accurately controlled, so that the heat received by different areas in the area on the substrate 11 corresponding to the internal thermal zone 121 can be consistent or nearly consistent with the heat required by the battery cell.

[0087] In some possible embodiments of the present application, the heating power of the inner heat zone 121 is smaller than the heating power of the surrounding heat zone 122 .

[0088] In the embodiment of the present application, when the specific structure of the heating element 12 is set, the heating power of the internal hot zone 121 in the heating element 12 can be set to be smaller than the heating power of the surrounding hot zone 122. For example, the density of the heating wire in the internal hot zone 121 can be made smaller than the density of the heating wire in the surrounding hot zone 122; the resistivity of the internal hot zone 121 can also be made smaller than the resistivity of the surrounding hot zone 122, so that when the same voltage is applied to the internal hot zone 121 and the surrounding hot zone 122, the heat generated by the internal hot zone 121 will be less than the heat generated by the surrounding hot zone 122. Alternatively, the voltage applied to the internal hot zone 121 and the surrounding hot zone 122 can also be controlled so that the heat generated by the internal hot zone 121 is less than the heat generated by the surrounding hot zone 122.

[0089] In the above embodiment, since the heating power of the internal heat zone 121 of the heating element 12 is smaller than the heating power of the surrounding heat zone 122, the heat received by the central area of ​​the substrate 11 can be less than the heat received by the edge area of ​​the substrate 11. Since the heat of the edge area of ​​the substrate 11 is dissipated more quickly than the heat of the central area of ​​the substrate 11, the temperature of the central area and the edge area on the substrate 11 can be made substantially the same, and thus the temperature of the battery cells located at different positions in the battery drying fixture 1 can be made substantially the same.

[0090] In some possible embodiments of the present application, refer to Figure 6 , Figure 7 and Figure 8 , Figure 6 This is a schematic diagram of the structure of the profiling block in the battery drying fixture provided in this application. Figure 7 This is a schematic cross-sectional view of the guide block in the battery drying fixture provided in this application. Figure 8 The schematic diagram of the structure of the guide block in the battery drying fixture provided by the present application. The limiting structure 13 includes a guide block 132 and a profiling block 133, the profiling block 133 is arranged on the substrate 11, and the guide block 132 is located on the side of the profiling block 133 away from the substrate 11; the battery cell profiling hole 131 includes a guide section 1311 and a limiting section 1312, the limiting section 1312 is arranged on the profiling block 133, and the guide section 1311 is arranged on the guide block 132, and the diameter of at least part of the guide section 1311 is larger than the diameter of the limiting section 1312.

[0091] In the present application embodiment, Figure 2 As shown, a guide block 132 may be provided in the position-limiting structure 13, and the guide block 132 is combined with the profiling block 133 to form the position-limiting structure 13. Alternatively, the guide block 132 and the profiling block 133 may be provided as an integrated structure.

[0092] Exemplarily, a plurality of profiling blocks 133 may be provided in the position-limiting structure 13, and the plurality of profiling blocks 133 may be arranged in parallel so that the plurality of profiling blocks 133 almost cover one side of the substrate 11. Alternatively, an integral profiling block 133 having a size close to that of the substrate 11 may be provided. The shape of the guide block 132 is substantially the same as that of the profiling block 133, and the guide block 132 is located on a side of the profiling block 133 away from the substrate 11, and the guide block 132 and the profiling block 133 may be fixedly connected as one body by bolts.

[0093] In another example, the profiling block 133 can be made of the same material as the substrate 11, for example, the profiling block 133 is made of metal materials such as aluminum, aluminum alloy, copper, and copper alloy, so that the heat generated by the heating element can be quickly transferred to the profiling block 133 through the substrate 11. The bottom of the battery cell can be heated by the substrate 11, and the side wall of the battery cell can be heated by the profiling block 133, which is conducive to improving the heating efficiency of the battery cell. The guide block 132 can be made of a material such as plastic that is less hard than the hardness of the battery cell. The thermal conductivity of plastic is worse than that of metal. The guide block 132 can not only reduce the scratching of the battery cell, but also slow down the loss of heat from the profiling block 133 to the surrounding environment.

[0094] Another example, Figure 6 As shown, a limiting segment 1312 may be provided on the profiling block 133, and the shape of the limiting segment 1312 is the same as the shape of the battery cell, for example, the limiting segment 1312 is a cylindrical hole or a square hole. Figure 7 and Figure 8 As shown, a guide segment 1311 can be provided on the guide block 132, and the shape of the guide segment 1311 is similar to the shape of the battery cell, and the diameter of the guide segment 1311 is larger than the diameter of the limiting segment 1312. For example, the guide segment 1311 can be provided as a truncated cone-shaped through hole, and the end of the truncated cone-shaped through hole with a diameter smaller than is adjacent to the limiting segment 1312. Alternatively, a limiting segment 1312 can also be provided on the guide member, and the diameter of the limiting segment 1312 on the guide member is consistent with the diameter of the limiting segment 1312 on the profiling block 133. Each guide segment 1311 on the guide member corresponds to a limiting segment 1312 on the profiling block 133, and the guide segment 1311 on the guide member is coaxially arranged with the corresponding limiting segment 1312 on the profiling block 133.

[0095] In the above embodiment, since the battery cell profiling hole 131 includes the guide segment 1311 and the limiting segment 1312, during the process of placing the battery cell into the battery cell profiling hole 131, the diameter of the guide segment 1311 is larger than the diameter of the limiting segment 1312, that is, the diameter of the guide segment 1311 is larger than the diameter of the battery cell, thereby making it easier for the battery cell to enter the battery cell profiling hole 131, which is beneficial to reducing the requirements for the movement accuracy of the equipment or device for transporting the battery cell.

[0096] In some possible embodiments of the present application, Figure 1 As shown, the battery drying fixture 1 further includes a flexible protective member 14 , which is fitted to the battery cell contour hole 131 , and the hardness of the flexible protective member 14 is less than the hardness of the battery cell.

[0097] In the embodiment of the present application, a flexible protective member 14 may be provided on the substrate 11 and the limiting structure 13, so that the battery cell abuts against the hole wall of the battery cell profiling hole 131 through the flexible protective member 14. For example, the flexible protective member 14 may be made of Teflon tape, or a film made of polytetrafluoroethylene, polyimide, or the like. Furthermore, the flexible protective member 14 may be made of a material having a hardness less than that of the battery cell.

[0098] For example, the flexible protective member 14 can be attached to the surface of the limiting structure 13 on the substrate 11 by bonding, and the flexible protective member 14 can be attached to the hole wall of the battery cell profiling hole 131, so that the side wall and the bottom of the battery cell profiling hole 131 are provided with the flexible protective member 14. In this way, after the battery cell is placed in the battery cell profiling hole 131, the battery cell directly contacts the flexible protective member 14.

[0099] In the above embodiment, since a flexible protective member 14 is provided in the battery cell profiling hole 131, the battery cell can be brought into contact with the flexible protective member 14 and move relative to the flexible protective member 14 during the process of placing the battery cell into the battery cell profiling hole 131 or taking the battery cell out of the battery cell profiling hole 131. Since the hardness of the flexible protective member 14 is less than the hardness of the battery cell, the risk of the battery cell being scratched by the battery drying clamp 1 is reduced.

[0100] In some possible embodiments of the present application, Figure 1 and Figure 2 As shown, the battery drying fixture 1 further includes a reflector 15 , which surrounds the limiting structure 13 . Along the overlapping direction Z of the limiting structure 13 and the substrate 11 , the height of the reflector 15 is greater than or equal to the height of the limiting structure 13 .

[0101] In the embodiment of the present application, a reflector 15 may be provided around the limiting structure 13. For example, the reflector 15 may be provided as a thin plate-shaped structure, so that the surface of the reflector 15 facing the limiting structure 13 may have good heat reflection performance. For example, tin foil may be provided on the surface of the reflector 15, or heat reflection paint may be applied on the surface of the reflector 15, so as to reflect the heat radiated from the limiting structure 13 by using the tin foil or the heat reflection paint.

[0102] Exemplarily, the reflector 15 can surround the limiting structure 13 in the circumferential direction thereof. Along the overlapping direction Z of the limiting structure 13 and the substrate 11, the height of the reflector 15 can be greater than or equal to the height of the limiting structure 13, such as the height of the reflector 15 is equal to the height of the limiting structure 13.

[0103] In the above embodiment, since the reflective member 15 is arranged around the limiting structure 13, the reflective member 15 can be used to reflect the heat radiated by the limiting structure 13 to the limiting structure 13, which is beneficial to slow down the speed of heat loss from the battery drying clamp 1 to the surrounding environment and improve energy utilization.

[0104] In some possible embodiments of the present application, Figure 1 and Figure 2 As shown, the battery drying fixture 1 further includes a first moving component 17 , which is disposed on the substrate 11 , and matches with the moving fixture 2 . The battery drying fixture 1 can move on the moving fixture 2 via the first moving component 17 .

[0105] In the embodiment of the present application, a first moving assembly 17 may be provided on two opposite sides of the substrate 11, so that the battery drying fixture 1 can be moved on the moving fixture 2 through the first moving assembly 17. For example, a plurality of first bearing wheels may be provided in the first moving assembly 17, and the plurality of first bearing wheels are respectively provided on two opposite sides of the substrate 11, and the axes of the first bearing wheels are parallel to the plane where the substrate 11 is located. The first bearing wheels may be rollers, and if seven rollers are respectively provided on two opposite sides of the substrate 11, the battery drying fixture 1 may be moved on the moving fixture 2 through the rollers.

[0106] For example, a first guide wheel 171 may be provided in the first moving assembly 17, and the first guide wheel 171 may be a roller, and the first guide wheel 171 may be provided at a position adjacent to the first bearing wheel on the substrate 11, and the axis of the first guide wheel 171 may be perpendicular to the substrate 11. The first guide wheel 171 may guide and limit the movement direction of the battery drying fixture 1 on the moving fixture 2.

[0107] In the above embodiment, since the first moving assembly 17 is provided on the substrate 11 , the battery drying fixture 1 can be easily moved relative to the moving fixture 2 through the first moving assembly 17 , which is beneficial to reduce the wear of the battery drying fixture 1 when it moves relative to the moving fixture 2 .

[0108] In some possible embodiments of the present application, Figure 1 and Figure 2 As shown, the battery drying clamp 1 also includes a first locking component 18, which is arranged on the substrate 11. When the battery drying clamp 1 is placed on the mobile clamp 2, the first locking component 18 can move relative to the substrate 11 and abut against the mobile clamp 2 to limit the movement of the battery drying clamp 1 relative to the mobile clamp 2.

[0109] In the embodiment of the present application, when the battery drying fixture 1 is placed on the mobile fixture 2, it is necessary to fix the battery drying fixture 1 on the mobile fixture 2, and a first locking component 18 can be provided on the battery drying fixture 1. For example, a group of first locking components 18 can be provided at two adjacent corners on the substrate 11, respectively, and the first locking components 18 can be provided as a structure capable of generating movement. In this way, after the battery drying fixture 1 is moved into place on the mobile fixture 2, the first locking component 18 can be controlled to move relative to the substrate 11, so that a part of the first locking component 18 abuts against the corresponding structure on the mobile fixture 2, thereby limiting the movement of the battery drying fixture 1 relative to the mobile fixture 2.

[0110] In the above embodiment, since the first locking component 18 is provided on the battery drying fixture 1, the first locking component 18 can be used to limit the movement of the battery drying fixture 1 relative to the movable fixture 2, so that after the battery drying fixture 1 moves into place on the movable fixture 2, the battery drying fixture 1 can be in a fixed position relative to the movable fixture 2, so as to facilitate the accurate placement of the battery cell into the battery cell profiling hole 131, or the removal of the battery from the battery cell profiling hole 131.

[0111] In addition, the present application also provides a battery drying device, referring to Fig. 9 , Fig. 9 The present invention provides a schematic diagram of the structure of a battery drying device. The battery drying device comprises: a mobile fixture 2 and a battery drying fixture 1 provided in any one of the above embodiments. The mobile fixture 2 comprises a carrier frame 21 and at least two carrier mechanisms 22, and the at least two carrier mechanisms 22 are stacked on the carrier frame 21 at intervals; the battery drying fixture 1 is movably carried on the carrier mechanism 22.

[0112] In the embodiment of the present application, the mobile clamp 2 is used to move the battery drying clamp 1. The battery drying clamp 1 can be moved to the drying station by the mobile clamp 2, and the battery drying clamp 1 carrying the battery cell is electrically connected to the power supply of the drying station through the connector 16 to achieve heating and drying of the battery cell.

[0113] For example, Fig. 9As shown, at least two bearing mechanisms 22 can be arranged on the bearing frame 21 of the mobile fixture 2, and the bearing mechanisms 22 match the battery drying fixture 1. The battery drying fixture 1 can be placed on the bearing mechanism 22 through the first moving component 17, or the battery drying fixture 1 can be taken out from the bearing mechanism 22 through the first moving component 17. For example, five bearing mechanisms 22 can be arranged on the bearing frame 21, and the five bearing mechanisms 22 are stacked in sequence, and there is a certain height gap between adjacent bearing mechanisms 22, and the gap between adjacent bearing mechanisms 22 is greater than the thickness of the battery drying fixture 1 containing the battery cells. Three, six, or other number of bearing mechanisms 22 can also be arranged on the bearing frame 21, and the specific number of the bearing mechanisms 22 is not limited in the embodiment of the present application.

[0114] The battery drying device provided in the embodiment of the present application includes the battery drying fixture 1 provided in the above embodiment, and therefore, can achieve uniform heating of all the battery cells carried in the battery drying fixture 1, so that all the battery cells in the battery drying fixture 1 have the same or nearly the same drying rate. And it is convenient to move the battery drying fixture 1 to the station for drying the battery cells by moving the included angle.

[0115] In some possible embodiments of the present application, refer to Fig.10 , Fig.10 Provided for this application Fig. 9 The partial enlarged schematic diagram of part A in the figure. The carrying mechanism 22 includes a first guide component 221, and the battery drying fixture 1 includes a first moving component 17 matched with the first guide component 221. The battery drying fixture 1 moves on the first guide component 221 through the first moving component 17 to enter the moving fixture 2 or exit from the moving fixture 2.

[0116] In the present application embodiment, Fig.10 As shown, a first guide assembly 221 may be provided in the carrier mechanism 22 to guide and limit the movement path of the battery drying fixture 1 in the mobile fixture 2 using the first guide assembly 221. For example, the first guide assembly 221 may be provided as a structure including a guide rail 2211 and an auxiliary member 2212, and both the guide rail 2211 and the auxiliary member 2212 are matched with the first mobile assembly 17 in the battery drying fixture 1.

[0117] Exemplarily, the guide rail 2211 in the first guide assembly 221 can be set as a strip track structure with a groove, and the auxiliary member 2212 in the first guide assembly 221 can be set as a flat long strip structure, and the guide rail 2211 and the auxiliary member 2212 are respectively located on opposite sides of the carrier 21. In this way, the first bearing wheel in the first moving assembly 17 can roll on the guide rail 2211 and the auxiliary member 2212, so that the battery drying fixture 1 can move on the carrier mechanism 22; the first guide wheel 171 can be clamped in the groove of the guide rail 2211 to limit the movement of the first bearing wheel along the extension direction of the guide rail 2211.

[0118] In the above embodiment, since a first guide component 221 matching the first movable component 17 in the battery drying fixture 1 is provided in the supporting mechanism 22, the battery drying fixture 1 can be moved relative to the movable fixture 2 on the supporting mechanism 22 through the first movable component 17 and the first guide component 221, thereby facilitating the battery drying fixture 1 to enter into the movable fixture 2 or to exit from the movable fixture 2.

[0119] In some possible embodiments of the present application, refer to Fig.11 , Fig.11 Provided for this application Fig. 9 The battery drying device further includes a first locking component 18 and a first positioning member 23 matched with the first locking component 18, wherein the first locking component 18 is disposed on one of the substrate 11 and the carrier 21, and the first positioning member 23 is disposed on the other of the substrate 11 and the carrier 21, and the first locking component 18 cooperates with the first positioning member 23 to limit the movement of the battery drying fixture 1 relative to the carrier 21.

[0120] In an embodiment of the present application, matching first locking components 18 and first positioning members 23 may be respectively provided on the substrate 11 in the battery drying fixture 1 and the carrier frame 21 in the mobile fixture 2, so as to limit the movement of the battery drying fixture 1 relative to the mobile fixture 2 through the cooperation of the first locking components 18 and the first positioning members 23.

[0121] For example, Fig. 9 and Fig.11 As shown, a first locking assembly 18 may be provided at two adjacent corners of the battery drying fixture 1, and two first positioning members 23 corresponding to the first locking assembly 18 may be provided at one end of each group of supporting mechanisms 22. Alternatively, a first positioning member 23 may be provided at two adjacent corners of the battery drying fixture 1, and two first locking assemblies 18 corresponding to the first positioning members 23 may be provided at one end of each group of supporting mechanisms 22.

[0122] Another example, such as Fig.11As shown, a first positioning block can be provided in the first positioning member 23, for example, the first positioning block is fixed at a position adjacent to the guide rail 2211 on the carrier 21, and a positioning hole facing the battery drying fixture 1 can be provided on the first positioning block. A first driving member 181 and a first locking member 182 can be provided in the first locking assembly 18, such as the first locking member 182 is provided as a rod-shaped structure matching the positioning hole on the first positioning block, the first driving member 181 can be fixed on the substrate 11, and the first driving member 181 can be a device capable of generating linear motion such as an air cylinder, an oil cylinder, or an electric cylinder, and the first locking member 182 is fixed to the output shaft of the first driving member 181. The first driving member 181 can drive the first locking member 182 to move in a direction close to or away from the first positioning block, so that the first locking member 182 is inserted into the positioning hole on the first positioning block, or the first locking member 182 is withdrawn from the positioning hole on the first positioning block.

[0123] In the above embodiment, since matching first locking components 18 and first positioning components 23 are respectively provided on the substrate 11 and the carrier frame 21, after the battery drying fixture 1 moves into place on the mobile fixture 2, the first locking component 18 can be controlled to abut against the first positioning component 23, so that the battery drying fixture 1 can be fixed to the mobile fixture 2 through the first locking component 18 and the first positioning component 23, thereby reducing the occurrence of unnecessary movement of the battery drying fixture 1 relative to the mobile fixture 2.

[0124] In some possible embodiments of the present application, Fig.10 and Fig.11 As shown, the battery drying device also includes a detection member 24 and a trigger member 25. The detection member 24 is arranged on one of the substrate 11 and the carrier frame 21, and the trigger member 25 is arranged on the other of the substrate 11 and the carrier frame 21. When the battery drying fixture 1 moves relative to the carrier frame 21 until the detection member 24 abuts against the trigger member 25, the detection member 24 can generate a control signal to control the movement of the first locking component 18.

[0125] In the embodiment of the present application, a detection member 24 and a trigger member 25 may be respectively provided on the substrate 11 and the carrier 21, so as to output a signal that the battery drying fixture 1 has moved into position on the mobile fixture 2 through the detection member 24. For example, the detection member 24 may be a contact switch, a proximity sensor, etc. The detection member 24 may be fixed on the carrier 21, such as fixing the detection member 24 on the side of the guide rail 2211. The trigger member 25 may be provided as a plate-like structure, and the trigger member 25 may be fixed on the substrate 11 at a position corresponding to the detection member 24. Alternatively, the detection member 24 may be fixed on the substrate 11, and the trigger member 25 may be fixed on the carrier 21. In this way, during the movement of the battery drying fixture 1 on the carrier mechanism 22, until the trigger member 25 abuts against the detection member 24, the detection member 24 may generate a control signal. For example, the control signal may be an electrical signal, and the movement of the first locking component 18, the push-pull mechanism 34, etc. may be controlled by the electrical signal.

[0126] Exemplarily, the detection member 24 can be electrically connected to the first driving member 181 in the first locking component 18. When the detection member 24 generates a control signal, the first driving member 181 can be controlled to perform a locking action so that the first driving member 181 drives the first locking member 182 to abut against the first positioning member 23.

[0127] In the above embodiment, since matching detection components 24 and trigger components 25 are respectively provided on the substrate 11 and the carrier frame 21, when the battery drying fixture 1 moves into position on the mobile fixture 2, a control signal can be generated in time through the detection component 24, so as to obtain the information that the battery drying fixture 1 moves into position on the mobile fixture 2 in time.

[0128] The present application also provides a battery drying system, referring to Fig.12 and Fig.13 , Fig.12 Schematic diagram of the battery drying system provided for this application Figure 1 , Fig.13 Schematic diagram of the battery drying system provided for this application Figure 2 . The battery drying system includes: a disassembly tray device and a battery drying device provided in the above embodiment. Among them, the disassembly tray device includes adjacent disassembly tools 3 and parking tools 4; the parking tool 4 is matched with the mobile fixture 2 so that the mobile fixture 2 can be movably carried on the parking tool 4; the disassembly tool 3 includes at least two drawer mechanisms 31 stacked at intervals on the disassembly tray frame 5, and the battery drying fixture 1 can be movably carried on the drawer mechanism 31; the disassembly tool 3 can move the battery drying fixture 1 located on the drawer mechanism 31 to the carrying mechanism 22, or move the battery drying fixture 1 located on the carrying mechanism 22 to the drawer mechanism 31.

[0129] In the embodiment of the present application, the disassembly tray device carries the battery drying fixture 1, so as to place the battery cell on the battery drying fixture 1, or remove the dried battery cell from the battery drying fixture 1. The disassembly tray device is also used to move multiple battery drying fixtures 1 to the mobile fixture 2, or to separate the battery drying fixture 1 from the mobile fixture 2, so as to realize the assembly of multiple battery drying fixtures 1 on the mobile fixture 2, or to complete the disassembly of the battery drying fixture 1 from the mobile fixture 2.

[0130] For example, Fig.12 and Fig.13 As shown, a parking tool 4 can be provided in the disassembly tray device, and the parking tool 4 matches the mobile fixture 2, and the mobile fixture 2 can be moved to the parking tool 4 and temporarily parked on the parking tool 4. After the disassembly or assembly of multiple battery drying fixtures 1 on the mobile fixture 2 is completed, the mobile fixture 2 can be moved from the parking tool 4 to other stations.

[0131] Another example, such as Fig.12 and Fig.13 As shown, a disassembling tool can be arranged at a position adjacent to the parking tool 4 in the disassembling tray device, and at least two drawer mechanisms 31 can be arranged in the disassembling tool. For example, a disassembling tray rack 5 can be arranged in the disassembling tray device, and the components in the disassembling tool 3 and the parking tool 4 can be installed on the disassembling tray rack 5. The drawer mechanism 31 can be arranged to match the battery drying fixture 1, so that the battery drying fixture 1 can move on the drawer mechanism 31.

[0132] In another example, multiple drawer mechanisms 31 can be stacked and fixed on the disassembly tray frame 5 in sequence, and there is a gap between adjacent drawer mechanisms 31. The gap between adjacent drawer mechanisms 31 can accommodate a battery drying fixture 1 with a battery cell. For example, the number of drawer mechanisms 31 can be the same as the number of carrier mechanisms 22 in the mobile fixture 2, that is, after the mobile fixture 2 is parked on the parking tool 4, the multiple drawer mechanisms 31 and the multiple carrier mechanisms 22 correspond to each other one by one. In this way, Fig.12 As shown, after placing the battery cell in the battery cell profiling hole 131 of the battery drying fixture 1 on the draw-out mechanism 31, the battery drying fixture 1 can be moved along the draw-out mechanism 31 to the carrier mechanism 22 corresponding to the draw-out mechanism 31, that is, the battery drying fixture 1 is moved from the disassembly tool to the mobile fixture 2. After the battery cell on the battery drying fixture 1 on the mobile fixture 2 is dried, the mobile fixture 2 can be moved to the parking tool 4, and then the battery drying fixture 1 is moved along the carrier mechanism 22 to the draw-out mechanism 31 corresponding to the carrier mechanism 22, that is, the battery drying fixture 1 is moved from the mobile fixture 2 to the disassembly tool, so as to facilitate the disassembly of the battery drying fixture 1.

[0133] The battery drying system provided in the embodiment of the present application includes the battery drying fixture 1 provided in the above embodiment, and therefore, uniform heating of all the battery cells carried in the battery drying fixture 1 can be achieved, so that all the battery cells in the battery drying fixture 1 have the same or nearly the same drying rate. In addition, adjacent disassembly tools and parking tools 4 are provided in the disassembly tray device, so as to facilitate the assembly or disassembly of multiple battery drying fixtures 1 on the mobile fixture 2.

[0134] In some possible embodiments of the present application, refer to Fig.14 , Fig.15 and Fig.16 , Fig.14 Provided for this application Fig.13 A partial enlarged schematic diagram of part C in the middle. Fig.15 Provided for this application Fig.13 A partial enlarged schematic diagram of part D in the figure. Fig.16 Provided for this application Fig.12 The partial enlarged schematic diagram of the E part. The drawer mechanism 31 includes a second guide assembly, which corresponds to the first guide assembly 221 in the mobile fixture 2 and matches the first moving assembly 17 of the battery drying fixture 1; the disassembly tool also includes a second locking assembly 32 arranged on the disassembly disk frame 5, and the battery drying fixture 1 also has a second positioning assembly matching the second locking assembly 32. When the battery drying fixture 1 moves from the first guide assembly 221 to the second guide assembly through the first moving assembly 17, the second locking assembly 32 cooperates with the second positioning assembly to limit the movement of the battery drying fixture 1 relative to the disassembly tool 3.

[0135] In the present application embodiment, Fig.12 As shown, a second guide assembly can be provided in the draw-out mechanism 31, and the second guide assembly can be provided as a structure including two guide members, the two guide members are provided opposite to each other on the disassembly tray frame 5, and the two guide members match the first movable assembly 17 in the battery drying fixture 1. For example, one guide member is provided as a plate-like structure with a groove, so that the first load-bearing wheel in the first movable assembly 17 can roll in the groove, and the first guide wheel 171 in the first movable assembly 17 can abut against the side wall of the groove to limit the movement direction of the battery drying fixture 1 on the draw-out mechanism 31. Another guide member is provided as a flat plate-like structure, so that the first load-bearing wheel in the first movable assembly 17 can roll on the flat plate. In this way, the movement of the battery drying fixture 1 on the disassembly tool 3 is realized through the second guide assembly and the first movable assembly 17.

[0136] In the present application embodiment, Fig.14As shown, a second locking component 32 may be provided in the disassembly tool 3 to fix the battery drying fixture 1 moved from the mobile fixture 2 to the drawer mechanism 31 through the second locking component 32 .

[0137] Exemplarily, the second locking component 32 can be configured to include a second driving member 322 and a second locking member 323. For example, the second carrier plate 321 can be fixed on the disassembly disk rack 5, such as fixing the second carrier plate 321 at a position adjacent to one end of the second guide component on the disassembly disk rack 5. The second locking member 323 can be configured to be a rod-shaped structure with a barb at one end, and the second locking member 323 can be rotatably disposed on the second carrier plate 321. The second driving member 322 can adopt a structure including a push rod and a compression spring, wherein the push rod is slidably disposed on the second carrier plate 321, the compression spring is sleeved on the push rod, and one end of the push rod is connected to an end of the second locking member 323 away from the barb. Correspondingly, a second positioning member 183 can be provided on the substrate 11 of the battery drying clamp 1, and the second positioning member 183 can be a block-shaped rectangular block. As Fig.14 As shown, after the battery drying fixture 1 moves into place on the drawer mechanism 31, under the action of the compression spring, the push rod moves in the direction away from the second positioning member 183, and the push rod drives the second locking accessory 323 to rotate, so that the barb hook on the second locking accessory 323 is hung on the second positioning member 183, thereby limiting the movement of the battery drying fixture 1 in the direction close to the parking tooling 4.

[0138] In the present application embodiment, Fig.14 As shown, the disassembly tool 3 also includes a buffer component 33, which is arranged at the end of the drawer mechanism 31 away from the parking tool 4 and can produce deformation along the extension direction of the second guide component; when the battery drying fixture 1 moves on the second guide component away from the first guide component 221, the buffer component 33 is deformed under the pressure of the battery drying fixture 1.

[0139] Exemplarily, the buffer assembly 33 can be set to a structure including a guide rod and a compression spring. For example, the guide rod can be slidably set on the second carrier plate 321 along the extension direction of the second guide assembly, and the compression spring can be sleeved on the guide rod. In this way, when the battery drying fixture 1 moves toward the second locking assembly 32, the side of the substrate 11 first contacts the guide rod. As the battery drying fixture 1 continues to move toward the second locking assembly 32, the compression spring sleeved on the guide rod is compressed. Under the action of the compression spring, the guide rod applies a force to the substrate 11 to decelerate the battery drying fixture 1 until the battery drying fixture 1 stops moving along the second guide assembly, which is conducive to reducing the occurrence of collisions between the battery drying fixture 1 and the disassembly tool 3. In this process, the second positioning member 183 pushes the second locking member 323 to rotate, so as to achieve the restriction of the movement of the battery drying fixture 1 by the second locking member 32, so as to fix the battery drying fixture 1 on the disassembly tool 3 through the buffer assembly 33 and the second locking member 32.

[0140] In the above embodiment, since the drawer mechanism 31 and the movable fixture 2 respectively include the corresponding second guide assembly and the first guide assembly 221, it is convenient to move the battery drying fixture 1 along the first guide assembly 221 and the second guide assembly through the first movable assembly 17, so as to realize the movement of the battery drying fixture 1 between the disassembly tool 3 and the movable fixture 2. And the movement of the battery drying fixture 1 relative to the disassembly tool 3 can be restricted by the cooperation of the second locking assembly 32 and the second positioning member 183.

[0141] In some possible embodiments of the present application, Fig.13 As shown, the disassembly tool 3 also includes a push-pull mechanism 34, which is slidably arranged on the disassembly disk frame 5 and corresponds to the drawer mechanism 31. The push-pull mechanism 34 can be locked or unlocked with the battery drying fixture 1. The push-pull mechanism 34 is used to drive the battery drying fixture 1 to move between the supporting mechanism 22 and the drawer mechanism 31.

[0142] In the embodiment of the present application, a push-pull mechanism 34 may be provided in the disassembly tool 3, so as to drive the battery drying fixture 1 to move behind the corresponding bearing mechanism 22 and the drawer mechanism 31 through the push-pull mechanism 34. For example, the push-pull mechanism 34 includes a push-pull bracket 341, a third locking component 342 and a push-pull driving member 343, the push-pull bracket 341 is slidably provided on the disassembly disk frame 5 along the first direction X, the third locking component 342 is movably provided on the push-pull bracket 341, the battery drying fixture 1 has a second positioning block matching the third locking component 342, and the push-pull driving member 343 is fixed to the push-pull bracket 341, and is used to drive the third locking component 342 to move along the first direction X, so as to drive the battery drying fixture 1 to move between the first guide component 221 and the second guide component through the cooperation of the third locking component 342 and the second positioning block; the first direction X is the extension direction of the second guide component.

[0143] For example, Fig.13 As shown, the push-pull bracket 341 can be set to slide along the first direction X on the side of the disassembling disk rack 5, the push-pull driving member 343 can be fixed on the disassembling disk rack 5, and the push-pull driving member 343 is connected to the push-pull bracket 341. For example, the push-pull driving member 343 can be a device that can generate linear motion, such as an electric cylinder, an air cylinder, or an oil cylinder. Then, the push-pull bracket 341 can be driven by the push-pull driving member 343 to reciprocate along the first direction X relative to the disassembling disk rack 5. A plurality of third locking components 342 can be fixed on the push-pull bracket 341, and each third locking component 342 corresponds to a drawer mechanism 31. A third positioning member 184 corresponding to the third locking component 342 can be provided on the battery drying fixture 1, so that the push-pull mechanism 34 and the battery drying fixture 1 can be locked or unlocked by connecting or separating the third locking component 342 and the third positioning member 184, so that the push-pull mechanism 34 can drive the battery drying fixture 1 to move between the supporting mechanism 22 and the drawer mechanism 31.

[0144] Another example, such as Fig.13 As shown, a push-pull mechanism 34 can be set on both sides of the disassembly disk frame 5 respectively, and the battery drying fixture 1 can be pushed from the disassembly tooling to the mobile fixture 2 on the parking tooling 4 through one of the push-pull mechanisms 34, and the battery drying fixture 1 can be pushed from the mobile fixture 2 to the disassembly tooling through the other push-pull mechanism 34.

The third locking component 3421 is slidably arranged on the push-pull bracket 341 along the second direction Y. The third locking component 3421 matches the second positioning block. The unlocking component 3422 is slidably arranged on the push-pull bracket 341 along the second direction Y. The unlocking component 3422 corresponds to the second locking component 32. The third driving component 3423 is fixed to the push-pull bracket 341 and is connected to both the third locking component 3421 and the unlocking component 3422. The third driving component 3423 is used to drive the third locking component 3421 and the unlocking component 3422 to move along the second direction Y, so that the third locking component 3421 is connected to or separated from the second positioning component 183, and the unlocking component 3422 is abutted against or separated from the second locking component 32; the second direction Y and the first direction X meet a vertical relationship.

The third carrier 3425 can be slidably provided on the push-pull bracket 341 along the second direction Y through the third sliding assembly 3424, and the third sliding assembly 3424 can adopt a matching guide rail 2211 and a slider. The third locking member 3421 is fixed on the third carrier 3425 so that the third locking member 3421 can move along the second direction Y, so that the third locking member 3421 is clamped on the third positioning member 184, or the third locking member 3421 is separated from the third positioning member 184. The third driving member 3423 can be an electric cylinder, a pneumatic cylinder, an oil cylinder, etc., and the third driving member 3423 is fixed on the push-pull bracket 341, and the output shaft of the third driving member 3423 is fixedly connected to the third carrier plate 3425. The unlocking member 3422 can be fixed on the third carrier plate 3425 at a position adjacent to the third locking member 3421, and the unlocking member 3422 corresponds to the second driving member 322 in the second locking assembly 32.

[0147] like Fig.15As shown, in the process that the third driving member 3423 drives the third locking accessory 3421 to approach the third positioning member 184, the unlocking member 3422 abuts against the second driving member 322 and pushes the second driving member 322 to slide, and the second driving member 322 drives the second locking accessory 323 to rotate, so that the second locking accessory 323 can be separated from the second positioning member 183 to achieve the unlocking of the second locking component 32 and the second positioning member 183, and the locking of the third locking accessory 3421 and the third positioning member 184, then the battery drying clamp 1 can be driven by the push-pull mechanism 34 to move in the direction of the first direction X towards the movable clamp 2.

[0148] In the above embodiment, since a push-pull mechanism 34 is provided in the disassembly tool 3, the push-pull mechanism 34 can drive the battery drying fixture 1 to move between the disassembly tool 3 and the movable fixture 2, so that the battery drying fixture 1 can be quickly assembled or disassembled in the movable fixture 2.
