[0004] New energy batteries are being used more and more widely in life and industry. For example, new energy vehicles equipped with batteries have been widely used. In addition, batteries are also being increasingly used in energy storage fields.

[0005] During the battery cell production process, bare cells need to be assembled with coating materials. However, in related technologies, when the coating material in the silo is used up, the production line needs to be shut down to replenish the silo, and then the production line needs to be run again to assemble the coating material in the silo with the bare cells, resulting in low production efficiency.

[0006] Summary of the Invention

[0007] The present disclosure provides a bare cell shelling production line and a cell production line, which can improve production efficiency.

[0008] In the first aspect, the present disclosure provides a bare cell shelling production line, which includes a bare cell conveying module, a coating material conveying module and an assembly module. The bare cell conveying module is configured to convey bare cells; the coating material conveying module includes a feeding mechanism and at least two material preparation components, at least two of which are identical to accommodate the same coating material, and the feeding mechanism is used to obtain the same coating material from the same material preparation component for conveying; the output end of the coating material conveying module and the bare cell conveying module are both connected to the assembly module, and the assembly module is configured to assemble the bare cells conveyed by the bare cell conveying module with the coating material conveyed by the coating material conveying module; the coating material conveying module includes a shell material conveying submodule; the shell material conveying submodule includes a shell material feeding mechanism and at least two shell material preparation components; the shell material conveying submodule It also includes a feed conveyor line and a moving mechanism; the feed conveyor line extends from the feed position to a position corresponding to the shell material feeding mechanism; the moving mechanism has an extended state and a retracted state, along the height direction of the feed conveyor line, when the moving mechanism is in the retracted state, the moving mechanism does not exceed the side of the feed conveyor line for placing the shell material preparation component; when the moving mechanism is in the extended state, the moving mechanism exceeds the side of the feed conveyor line for placing the shell material preparation component, so as to lift the shell material preparation component from the feed conveyor line and transport it to one side of the feed conveyor line, so that the shell material feeding mechanism can obtain shell materials from at least two shell material preparation components for transportation.

[0009] By making the feeding mechanism obtain the same coating material from the same preparation component for transportation, when the feeding mechanism obtains the coating material from one preparation component for transportation, the other identical preparation components are in an idle state, which is convenient for replenishment. In this way, when the bare cell shell production line is running, at least one of all the identical preparation components contains the coating material, and the feeding mechanism can always obtain the coating material for transportation. The bare cell shell production line does not need to be shut down when the coating material on one preparation component is used up, which is conducive to improving production efficiency. By making the moving mechanism move the shell material preparation component on the feed conveyor line to one side of the feed conveyor line, the feed conveyor line can drive at least two shell material preparation components from the feed position to the position corresponding to the shell material feeding mechanism, so that the shell material feeding mechanism obtains the shell material from at least two shell material preparation components for transportation, and the bare cell shell production line does not need to be shut down, which is more convenient to implement.

[0010] For example, after the coating material on the first preparation assembly is used up, the feeding mechanism can obtain the same coating material from the same second preparation assembly for delivery, so that the assembly module can still assemble the coating material with the bare cell. When the feeding mechanism obtains the coating material from the second preparation assembly, the first preparation assembly is idle, which is convenient for refilling. When the coating material on the second preparation assembly is used up, the feeding mechanism can switch to the first preparation assembly to obtain the coating material. The bare cell shell production line does not need to be shut down, which is conducive to improving production efficiency.

[0011] In some implementations of the present disclosure, the coating material conveying module includes a film material conveying submodule, which includes a film material feeding mechanism and at least two film material preparation components. The film material feeding mechanism is used to obtain film materials from at least two film material preparation components for conveying.

[0012] By making the film material feeding mechanism obtain film material from at least two film material preparation components for transportation respectively, when the film material feeding mechanism obtains film material from one film material preparation component for transportation, the other film material preparation components are in an idle state, which is convenient for replenishment. In this way, when the bare battery cell shell production line is running, at least one of all the film material preparation components contains film material, the film material feeding mechanism can always obtain film material for transportation, and the bare battery cell shell production line does not need to stop when the film material on one film material preparation component is used up, which is conducive to improving production efficiency.

[0013] In some implementations of the present disclosure, the film material feeding mechanism includes a first frame and a film material picking piece. The first frame is fixed relatively to at least two film material preparation assemblies. The film material picking piece can be movably arranged on the first frame so that the film material picking piece can move relative to the first frame to positions corresponding to the at least two film material preparation assemblies, so as to respectively obtain film materials from the at least two film material preparation assemblies, so that the film material feeding mechanism can respectively obtain film materials from the at least two film material preparation assemblies for transportation.

[0014] By fixing the first frame and at least two film material preparation assemblies relative to each other, the film material picking member moves relative to the first frame to positions corresponding to the at least two film material preparation assemblies to obtain film material for conveying. The structure of the film material feeding mechanism is relatively simple and easy to implement.

[0015] In some implementations of the present disclosure, at least two film material preparation assemblies are arranged along a first direction; the first frame is arranged across the at least two film material preparation assemblies along the first direction, and the film material picking piece is slidably connected to the first frame along the first direction, so that along the first direction, the film material picking piece can move to a position flush with the at least two film material preparation assemblies respectively, so as to obtain film materials from the at least two film material preparation assemblies respectively for transportation.

[0016] By making the first frame span between at least two film material preparation assemblies along the first direction, the film material picking part slides relative to the first frame along the first direction to move to a position corresponding to the at least two film material preparation assemblies, which is conducive to making the structure of the feeding mechanism simpler and more convenient to implement.

[0017] In some implementations of the present disclosure, the film material preparation assembly includes a base material preparation part and a film material preparation part, and the base material preparation part and the film material preparation part are arranged along a first direction.

[0018] By arranging the base stock part and the diaphragm stock part along the first direction, the film material picking part can slide relative to the first frame to move to positions corresponding to the base stock part and the diaphragm stock part, respectively. That is, a single film material picking part can be used to pick up materials from both the base stock part and the diaphragm stock part, which is relatively convenient and helps reduce costs. Moreover, even if two film material picking parts are provided, the two film material picking parts take materials from the base stock part and the diaphragm stock part respectively, and the base stock part and the diaphragm stock part are arranged along the first direction, the two film material picking parts can be connected to the first frame via the same slide rail extending along the first direction, which is relatively convenient and helps reduce costs.

[0019] In some implementations of the present disclosure, the number of film material picking parts is at least two, and the at least two film material picking parts include a bottom support picking part and a film sheet picking part; along the first direction, all bottom support picking parts are adjacently arranged, and all film sheet picking parts are adjacently arranged.

[0020] By arranging all the bottom support stock parts adjacent to each other and all the diaphragm stock parts adjacent to each other, it is helpful to reduce the risk of interference between the bottom support stock parts and the diaphragm stock parts during their relative movement to the frame.

[0021] In some implementations of the present disclosure, the film material preparation assembly includes a base support preparation part and / or a film sheet preparation part; the first frame is fixed relatively to the hot melt machine, and along the first direction, the film material picking part can move relative to the first frame to a position flush with the hot melt machine, so that the base support and / or the film sheet can be transported by the film material preparation assembly to the hot melt machine to make the battery cell film.

[0022] By making the film material picking part slide relative to the first frame, it moves to a position flush with the film material preparation assembly and the hot melt machine respectively, so as to transport the base and / or film sheet to the hot melt machine, and the hot melt machine hot-melts the base and film sheet to form a battery cell film, which is conducive to making the structure of the film material feeding mechanism simpler and more convenient to implement.

[0023] In some implementations of the present disclosure, along the first direction, the hot melt machine and all the film material preparation components are adjacently arranged.

[0024] By arranging all film material preparation components adjacent to each other and the hot melt machine on one side of all film material preparation components, the space around the hot melt machine is larger, which makes it convenient to set up a conveying mechanism near the hot melt machine to convey the battery cell film made by the hot melt machine to the assembly module.

[0025] In some implementations of the present disclosure, the feed conveyor line is a feed roller conveyor, and there is a first gap between two adjacent rollers of the feed roller conveyor along the length direction of the feed roller conveyor; the moving mechanism is arranged corresponding to the first gap, so that along the height direction of the feed roller conveyor, the moving mechanism can pass through the first gap to lift the shell material preparation assembly from the feed roller conveyor.

[0026] By enabling the moving mechanism to pass through the first gap to lift the shell material preparation assembly from the feed roller, the moving mechanism can support the shell material preparation assembly in the middle of the length direction of the feed roller to lift the shell material preparation assembly from the feed roller, and the supporting effect of the moving mechanism on the shell material preparation assembly is relatively stable.

[0027] In some implementations of the present disclosure, the first interval passes through the first side of the feed roller along the width direction of the feed roller; the shell material conveying submodule also includes a discharging roller, and there is a second interval between two adjacent rollers of the discharging roller along the discharging direction, and the second interval passes through the first side of the discharging roller along the width direction of the discharging roller, so that the moving mechanism can move from the first interval to the second interval through the first side of the feed roller and the first side of the discharging roller, so as to drive the shell material preparation assembly from the feed roller to the discharging roller, so that the discharging roller conveys the shell material preparation assembly to the discharging bracket.

[0028] By having the transport mechanism drive the shell material preparation assembly away from the feed roller conveyor through the first side of the feed roller conveyor, the shell material preparation assembly is more convenient to move. By having the transport mechanism move through the first side of the discharge roller conveyor to the second interval to drive the shell material preparation assembly from the feed roller conveyor to the discharge roller conveyor, when the transport mechanism places the shell material preparation assembly on the discharge roller conveyor, the discharge roller conveyor has a larger support area for the shell material preparation assembly, making the discharge roller conveyor more stable in supporting the shell material preparation assembly.

[0029] In some implementations of the present disclosure, the first interval passes through the first side of the feed roller along the width direction of the feed roller; the shell material conveying submodule also includes a discharging roller, and there is a second interval between adjacent rollers of the discharging roller along the discharging direction, and the second interval passes through the first side of the discharging roller along the width direction of the discharging roller; the moving mechanism includes a lifting member and a moving conveyor line arranged at the top end of the lifting member, and when the moving mechanism is in an extended state, one end of the lifting member is located in the first interval, and the other end extends through the first side of the feed roller and the first side of the discharging roller to the second interval; the extension path of the moving conveyor line matches the extension path of the lifting member, so that the moving conveyor line can move from the feed roller to the discharging roller, so that the discharging roller can convey the shell material preparation assembly to the discharging bracket.

[0030] By extending the lifting member through the first side of the feed roller conveyor to one side of the feed roller conveyor, the transport conveyor line provided on the lifting member can transport the shell material preparation assembly to one side of the feed roller conveyor along the width direction of the feed roller conveyor, which is relatively convenient to implement. By extending the lifting member through the first side of the discharge roller conveyor to the second interval of the discharge roller conveyor, the transport conveyor line provided on the lifting member can transport the shell material preparation assembly to the discharge roller conveyor along the width direction of the discharge roller conveyor, which is relatively convenient to implement. Moreover, when the transport mechanism places the shell material preparation assembly on the discharge roller conveyor, the discharge roller conveyor has a larger support area for the shell material preparation assembly, making the discharge roller conveyor more stable in supporting the shell material preparation assembly.

[0031] In some implementations of the present disclosure, the discharging roller and the feeding roller are arranged along the width direction of the feeding roller.

[0032] By arranging the discharge roller and the feed roller along the width direction of the feed roller, the moving mechanism only needs to drive the shell material preparation assembly to move along the width direction of the discharge roller to transport the shell material preparation assembly to the discharge roller, which is more convenient to implement.

[0033] In some implementations of the present disclosure, the width direction of the discharge roller is parallel to the width direction of the feed roller.

[0034] By making the width direction of the discharge roller parallel to the width direction of the feed roller, the shell material preparation assembly does not need to have a large bend in the movement path when moving from the feed roller to the discharge roller, which is more convenient to implement.

[0035] In some implementations of the present disclosure, the discharge roller includes a first roller and a second roller, and the first roller and the second roller form a first interval; the discharge roller includes a third roller and a fourth roller, and the third roller and the fourth roller form a second interval; along the length direction of the feed roller, the first roller is flush with the third roller, and the second roller is flush with the fourth roller.

[0036] By making the first roller flush with the third roller and the second roller flush with the fourth roller along the length direction of the feed roller, the part of the moving mechanism supporting the shell material preparation assembly only needs to move along the width direction of the discharge roller to transport the shell material preparation assembly to the discharge roller, which is more convenient to implement.

[0037] In some implementations of the present disclosure, the height direction of the discharge roller is parallel to the height direction of the feed roller.

[0038] By making the height direction of the discharge roller parallel to the height direction of the feed roller, the posture of the shell material preparation assembly does not need to change significantly during the process of transferring the shell material preparation assembly from the feed roller to the discharge roller. The discharge roller can provide relatively stable support for the shell material preparation assembly, which is conducive to making it easier for the moving mechanism to move the shell material preparation assembly.

[0039] In some implementations of the present disclosure, the coating material conveying module includes an adhesive material conveying submodule, which includes an adhesive material feeding mechanism and at least two adhesive material preparation components. The adhesive material feeding mechanism is used to obtain adhesive materials from at least two adhesive material preparation components for conveying.

[0040] By making the adhesive feeding mechanism obtain adhesive from at least two adhesive preparation assemblies for conveying respectively, when the adhesive feeding mechanism obtains adhesive from one adhesive preparation assembly for conveying, the other adhesive preparation assemblies are in an idle state, which is convenient for replenishing. In this way, when the bare cell shelling production line is running, at least one of all the adhesive preparation assemblies contains adhesive, the adhesive feeding mechanism can always obtain adhesive for conveying, and the bare cell shelling production line does not need to be shut down when the adhesive on one adhesive preparation assembly is used up, which is conducive to improving production efficiency.

[0041] In some implementations of the present disclosure, the adhesive feeding mechanism includes a second frame and an adhesive picking piece. The second frame is relatively fixed to at least two adhesive preparation assemblies. The adhesive picking piece is movably arranged on the second frame so that it can move relative to the second frame to positions corresponding to at least two adhesive preparation assemblies, so as to respectively obtain adhesives from at least two adhesive preparation assemblies, so that the adhesive feeding mechanism respectively obtains adhesives from at least two adhesive preparation assemblies for transportation.

[0042] By fixing the second frame relative to at least two adhesive material preparation assemblies, the adhesive material picking part moves relative to the second frame to positions corresponding to at least two adhesive material preparation assemblies to obtain adhesive for transportation. The structure of the adhesive material feeding mechanism is relatively simple and easy to implement.

[0043] In some implementations of the present disclosure, at least two adhesive material preparation assemblies are arranged along the second direction; the adhesive material picking piece is slidingly connected to the second frame along the second direction so that the adhesive material picking piece can move to positions corresponding to the at least two adhesive material preparation assemblies respectively.

[0044] By making the second frame span between at least two adhesive material preparation assemblies along the second direction, the adhesive material picking part slides relative to the second frame along the second direction to move to a position corresponding to the at least two adhesive material preparation assemblies, which helps to make the structure of the feeding mechanism simpler and more convenient to implement.

[0045] In some implementations of the present disclosure, the coating material conveying module also includes a film material conveying sub-module and an adhesive material conveying sub-module; the film material conveying sub-module includes a film material feeding mechanism and at least two film material preparation components, and the film material feeding mechanism is used to obtain film materials from at least two film material preparation components for conveying; the adhesive material conveying sub-module includes an adhesive material feeding mechanism and at least two adhesive material preparation components, and the adhesive material feeding mechanism is used to obtain adhesives from at least two adhesive material preparation components for conveying; along the conveying direction of the bare cell conveying module, the output end of the film material conveying sub-module, the output end of the adhesive material conveying sub-module and the output end of the shell material conveying sub-module are arranged in sequence.

[0046] By making the film material feeding mechanism, adhesive material preparation assembly and shell material feeding mechanism obtain film materials from corresponding at least two preparation assemblies for transportation respectively, the film material transportation submodule, shell material transportation submodule and adhesive material transportation submodule can all feed materials without stopping, which is conducive to improving production efficiency.

[0064] Hereinafter, the present disclosure will be described in detail.

[0065] During the battery cell production process, bare cells need to be assembled with coating materials. However, in related technologies, when the coating material in the silo is used up, the production line needs to be shut down to replenish the silo, and then the production line needs to be run again to assemble the coating material in the silo with the bare cells, resulting in low production efficiency.

The bare cell conveying module is configured to convey bare cells; the coating material conveying module includes a feeding mechanism and at least two material preparation components, the feeding mechanism is used to obtain the same coating material from the same material preparation component for conveying; the output end of the coating material conveying module and the bare cell conveying module are both connected to the assembly module, and the assembly module is configured to assemble the bare cells conveyed by the bare cell conveying module with the coating material conveyed by the coating material conveying module. By making the feeding mechanism obtain the same coating material from the same material preparation component for conveying, when the feeding mechanism obtains the coating material from one material preparation component for conveying, the other same material preparation components are in an idle state, which is convenient for replenishing materials. In this way, when the bare cell shell production line is running, at least one of all the same material preparation components contains coating material, and the feeding mechanism can always obtain coating material for conveying. The bare cell shell production line does not need to be shut down when the coating material on one material preparation component is used up, which is conducive to improving production efficiency.

The welding equipment is used to weld the cover material to the shell material; the conveying device is used to transport the bare cell and shell material assembly from the bare cell shell production line to the welding equipment.

[0068] In the embodiments of the present disclosure, the battery cell may be a secondary battery, and the battery cell may refer to a lithium-ion battery, a sodium-ion battery, a sodium-lithium-ion battery, a lithium metal battery, a sodium metal battery, a sodium-sulfur battery, a magnesium-ion battery, a nickel-hydrogen battery, a nickel-cadmium battery or a lead-acid battery, etc., and the embodiments of the present disclosure are not limited to this.

[0069] The embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0070] Please refer to Figure 1, which is a schematic diagram of the structure of the bare cell shell production line in some embodiments of the present disclosure. The bare cell shell production line provided by the present disclosure includes a bare cell conveying module 1, a coating material conveying module and an assembly module. Among them, the bare cell conveying module 1 is configured to convey bare cells; the coating material conveying module includes a feeding mechanism and at least two material preparation components, at least two of which are identical to accommodate the same coating material, and the feeding mechanism is used to obtain the same coating material from the same material preparation component for conveying; the output end of the coating material conveying module and the bare cell conveying module 1 are both connected to the assembly module, and the assembly module is configured to assemble the bare cells conveyed by the bare cell conveying module 1 with the coating material conveyed by the coating material conveying module.

[0071] The bare cell conveying module 1 in the embodiments of the present disclosure may have various implementation forms. For example, in some embodiments of the present disclosure, the bare cell conveying module 1 may be a conveying line.

[0072] The output end of the coating material conveying module and the bare cell conveying module 1 in the embodiment of the present disclosure are both connected to the assembly module. The assembly module is configured to assemble the bare cells conveyed by the bare cell conveying module 1 with the coating material conveyed by the coating material conveying module, that is, the feeding mechanism can convey the coating material from the material preparation component to the assembly module, and the bare cell conveying module 1 can convey the bare cells to the assembly module, so that the assembly module assembles the bare cells conveyed by the bare cell conveying module 1 with the coating material conveyed by the coating material conveying module.

[0073] The coating material in the embodiment of the present disclosure can have multiple implementation forms, and the coating material can include one coating material or multiple coating materials. Exemplarily, the coating material can include a cell film for coating a bare cell, an adhesive for coating the outer surface of the bare cell, and a cell shell for coating the bare cell.

Different types of feeding mechanisms are used to obtain coating materials from the same material preparation components of corresponding types for transportation. Different types of material preparation components can accommodate different types of coating materials.

[0075] By making the feeding mechanism obtain the same coating material from the same preparation component for transportation, when the feeding mechanism obtains the coating material from one preparation component for transportation, the other identical preparation components are in an idle state, which is convenient for replenishment.

The bare cell shell production line does not need to be shut down when the coating material on one preparation component is used up, which is conducive to improving production efficiency.

[0076] For example, after the coating material on the first preparation assembly is used up, the feeding mechanism can obtain the same coating material from the same second preparation assembly for delivery, so that the assembly module can still assemble the coating material with the bare cell. When the feeding mechanism obtains the coating material from the second preparation assembly, the first preparation assembly is idle, which is convenient for refilling. When the coating material on the second preparation assembly is used up, the feeding mechanism can switch to the first preparation assembly to obtain the coating material. The bare cell shell production line does not need to be shut down, which is conducive to improving production efficiency.

All film material preparation assemblies in the disclosed embodiments are used to accommodate film materials, and all film material preparation assemblies can accommodate the same film materials. Each film material preparation assembly can accommodate one type of film material, or multiple types of film materials.

[0080] By making the film material feeding mechanism obtain film material from at least two film material preparation components for transportation respectively, when the film material feeding mechanism obtains film material from one film material preparation component for transportation, the other film material preparation components are in an idle state, which is convenient for replenishment. In this way, when the bare battery cell shell production line is running, at least one of all the film material preparation components contains film material, the film material feeding mechanism can always obtain film material for transportation, and the bare battery cell shell production line does not need to stop when the film material on one film material preparation component is used up, which is conducive to improving production efficiency.

[0081] In some embodiments of the present disclosure, please refer to Figures 1, 2 and 3. The film material feeding mechanism includes a first frame 31 and a film material picking piece. The first frame 31 is relatively fixed to at least two film material preparation components. The film material picking piece can be movably arranged on the first frame 31 so that the film material picking piece can move relative to the first frame 31 to positions corresponding to at least two film material preparation components, so as to obtain film materials from at least two film material preparation components respectively, so that the film material feeding mechanism can obtain film materials from at least two film material preparation components for transportation.

[0082] The film material picking component in the embodiment of the present disclosure can be implemented in various forms. For example, it can be a suction cup or a gripping mechanism, etc. The suction cup can suck the film material from the film material preparation component, and the gripping mechanism can grab the film material from the film material preparation component.

[0083] By fixing the first frame 31 relative to at least two film material preparation assemblies, the film material picking member moves relative to the first frame 31 to positions corresponding to at least two film material preparation assemblies to obtain film material for conveying. The structure of the film material feeding mechanism is relatively simple and easy to implement.

[0084] In some embodiments of the present disclosure, please refer to Figures 1, 2 and 3, at least two film material preparation assemblies are arranged along a first direction a; the first frame 31 is arranged between the at least two film material preparation assemblies along the first direction a, and the film material picking part is slidably connected to the first frame 31 along the first direction a, so that along the first direction a, the film material picking part can move to a position flush with the at least two film material preparation assemblies respectively, so as to obtain film materials from the at least two film material preparation assemblies respectively for transportation.

[0085] The first direction a in the embodiment of the present disclosure may extend along a straight line, or may not extend along a straight line, such as extending along a curve or a broken line.

[0086] By making the first frame 31 span between at least two film material preparation components along the first direction a, the film material picking part slides relative to the first frame 31 along the first direction a to move to a position corresponding to at least two film material preparation components, which is conducive to making the structure of the feeding mechanism simpler and more convenient to implement.

[0087] In some embodiments of the present disclosure, please refer to Figures 1, 2 and 3. The film material can be supported on the upper side of the film material preparation assembly, the first frame 31 is arranged across the top of the film material preparation assembly, and the material picking part is directed downward to obtain the film material on the film material preparation assembly.

[0088] In some embodiments of the present disclosure, referring to Figures 1, 2, and 3, the number of film material delivery submodules 3 can be multiple to enable multi-station loading. For example, there can be two. The multiple film material delivery submodules are arranged side by side in a direction perpendicular to the first direction a.

[0089] In some embodiments of the present disclosure, referring to FIG. 1 , FIG. 2 and FIG. 3 , the film material preparation assembly includes a base preparation part 32 and a diaphragm preparation part 33 , and the base preparation part 32 and the diaphragm preparation part 33 are arranged along a first direction a.

[0090] The base stock 32 in the disclosed embodiment is used to accommodate the base, which is a type of membrane material. The diaphragm stock 33 in the disclosed embodiment is used to accommodate the diaphragm, which is a type of membrane material. The diaphragm and the base have the same meaning as those generally understood by those skilled in the art, and the diaphragm and the base are used to heat-seal and connect to form the battery cell membrane.

[0091] By arranging the bottom support stock part 32 and the diaphragm stock part 33 along the first direction a, the film material picking part can slide relative to the first frame 31 to move to the positions corresponding to the bottom support stock part 32 and the diaphragm stock part 33, that is, the film material picking part can be used to pick up materials from the bottom support stock part 32 and the diaphragm stock part 33, which is more convenient and helps to reduce costs. Moreover, even if two film material picking parts are provided, the two film material picking parts take the materials from the bottom support stock part 32 and the diaphragm stock part 33 respectively, and the bottom support stock part 32 and the diaphragm stock part 33 are arranged along the first direction a, the two film material picking parts can be connected to the first frame 31 through the same slide rail extending along the first direction a, which is more convenient and helps to reduce costs.

[0092] In some embodiments of the present disclosure, please refer to Figures 1, 2 and 3. The number of film material picking parts is at least two, and the at least two film material picking parts include a bottom support picking part and a film sheet picking part; along the first direction a, all bottom support preparation parts 32 are adjacently arranged, and all film sheet preparation parts 33 are adjacently arranged.

[0093] The base material taking part in the embodiment of the present disclosure is used to obtain the base from the base material preparation part 32 , and the diaphragm material taking part is used to obtain the diaphragm from the diaphragm material preparation part 33 .

[0094] By arranging all the bottom support stock parts 32 adjacent to each other and all the diaphragm stock parts 33 adjacent to each other, it is helpful to reduce the risk of interference between the bottom support stock parts and the diaphragm stock parts during their relative movement to the frame.

[0095] In some embodiments of the present disclosure, please refer to Figures 1, 2 and 3. The film material preparation assembly includes a base preparation part 32 and / or a film sheet preparation part 33; the first frame 31 is relatively fixed to the hot melt machine 34, and along the first direction a, the film material picking part can move relative to the first frame 31 to a position flush with the hot melt machine 34, so that the base and / or film sheet can be transported by the film material preparation assembly to the hot melt machine 34 to make the battery cell film.

[0096] By making the film material picking part slide relative to the first frame 31, so as to move to a position flush with the film material preparation assembly and the hot melt machine 34 respectively, the base and / or film sheet can be transported to the hot melt machine 34, so that the hot melt machine 34 can hot-melt the base and film sheet to form a battery cell film, which is conducive to making the structure of the film material feeding mechanism simpler and more convenient to implement.

[0097] In some embodiments of the present disclosure, referring to FIG. 1 , FIG. 2 and FIG. 3 , along a first direction a, the hot melt machine 34 and all the film material preparation components are adjacently arranged.

[0098] By arranging all the film material preparation components adjacent to each other, the hot melt machine 34 is arranged on one side of all the film material preparation components. The space around the hot melt machine 34 is larger, which makes it convenient to set up a conveying mechanism near the hot melt machine 34 to convey the battery cell film made by the hot melt machine 34 to the assembly module.

[0099] In some embodiments of the present disclosure, please refer to Figures 1, 4 and 5. The coating material conveying module includes a shell material conveying sub-module 4, and the shell material conveying sub-module 4 includes a shell material feeding mechanism 41 and at least two shell material preparation components 42. The shell material feeding mechanism 41 is used to obtain shell materials from at least two shell material preparation components 42 for conveying.

[0100] The shell material feeding mechanism 41 in the embodiment of the present disclosure is a type of feeding mechanism included in the coating material conveying module, that is, the coating material conveying module may include several feeding mechanisms, and several of the several feeding mechanisms are the shell material feeding mechanisms 41.

[0101] The shell material preparation component 42 in the embodiment of the present disclosure is a type of preparation component included in the coating material conveying module, that is, the coating material conveying module may include several preparation components, and several of the preparation components are shell material preparation components 42. All shell material preparation components 42 in the embodiment of the present disclosure are used to accommodate shell materials, and the shell material is the battery cell shell, which is a type of coating material. Generally, the shell material is an aluminum shell. The cover material used for welding with the shell material is the battery cell top cover. The bare battery cell is placed in the shell material through the opening on the shell material. The cover material is combined with the opening by welding, and together with the shell material, it forms a closed space for accommodating the bare battery cell.

[0102] By making the shell material feeding mechanism 41 obtain shell material from at least two shell material preparation components 42 for transportation respectively, when the shell material feeding mechanism 41 obtains shell material from one shell material preparation component 42 for transportation, the other shell material preparation components 42 are in an idle state, which is convenient for replenishment. In this way, when the bare battery cell shelling production line is running, at least one of all the shell material preparation components 42 contains shell material, the shell material feeding mechanism 41 can always obtain shell material for transportation, and the bare battery cell shelling production line does not need to stop when the shell material on one shell material preparation component 42 is used up, which is conducive to improving production efficiency.

[0103] In some embodiments of the present disclosure, referring to Figures 1, 4 and 5, the shell material conveying submodule 4 also includes a feed conveying line 43 and a moving mechanism; the feed conveying line 43 extends from the feed position to a position corresponding to the shell material feeding mechanism 41, so as to convey the shell material preparation component 42 from the feed position to a position corresponding to the shell material feeding mechanism 41, so that the shell material feeding mechanism 41 obtains the shell material from the shell material preparation component 42 for conveying; the moving mechanism has an extended state and a retracted state, and is arranged in a height direction along the feed conveying line 43. When the moving mechanism is in the retracted state, the moving mechanism does not exceed the side of the feed conveyor line 43 for placing the shell material preparation component 42; when the moving mechanism is in the extended state, the moving mechanism exceeds the side of the feed conveyor line 43 for placing the shell material preparation component 42, so as to lift the shell material preparation component 42 from the feed conveyor line 43 and transport it to one side of the feed conveyor line 43, so that the feed conveyor line 43 can respectively drive at least two shell material preparation components 42 to the position corresponding to the shell material feeding mechanism 41.

[0104] By making the moving mechanism move the shell material preparation component 42 on the feeding conveyor line 43 to one side of the feeding conveyor line 43, the feeding conveyor line 43 can respectively drive at least two shell material preparation components 42 from the feeding position to the position corresponding to the shell material feeding mechanism 41, so that the shell material feeding mechanism 41 can respectively obtain the shell material from at least two shell material preparation components 42 for transportation, thereby realizing the non-stop production line for bare cell shelling, which is relatively convenient to implement.

[0105] For example, the feed conveyor line 43 first conveys the first shell material preparation component 42 from the feed position to the position corresponding to the shell material feeding mechanism 41, and the shell material feeding mechanism 41 obtains the shell material on the first shell material preparation component 42 for conveying. When the shell material on the first shell material preparation component 42 is used up, the moving mechanism moves the first shell material preparation component 42 to one side of the feed conveyor line 43, and then the feed conveyor line 43 conveys the second shell material preparation component 42 from the feed position to the position corresponding to the shell material feeding mechanism 41, so that the shell material feeding mechanism 41 can obtain the shell material on the second shell material preparation component 42 for conveying, thereby realizing that the shell material feeding mechanism 41 obtains shell material from at least two shell material preparation components 42 for conveying.

[0106] In addition, by having the moving mechanism lift the shell material preparation assembly 42 from the feed conveyor line 43, the moving mechanism is unlikely to affect the operation of the shell material feeding mechanism 41 in obtaining shell materials from the shell material preparation assembly 42. Generally, the shell material feeding mechanism 41 is arranged on the upper side of the feed conveyor line 43, and the corresponding position of the feed conveyor line 43 and the shell material feeding mechanism 41 is located directly below the shell material feeding mechanism 41. It can be understood that the upper side of the feed conveyor line 43 is used to place the shell material preparation assembly 42, and the shell material feeding mechanism 41 is arranged on the upper side of the feed conveyor line 43 to conveniently obtain materials. The moving mechanism moves the shell material preparation assembly 42 by lifting the shell material preparation assembly 42 from the feed conveyor line 43 from bottom to top, so that the moving mechanism and the shell material feeding mechanism 41 are unlikely to have a significant impact.

[0107] In some embodiments of the present disclosure, referring to Figures 1, 4, and 5, a material rack is provided at the feed position, and the material rack is used to carry the shell material preparation assembly 42. The feed conveyor line 43 obtains the shell material preparation assembly 42 from the material rack and conveys it to a position corresponding to the shell material feeding mechanism 41. A motion mechanism such as a roller can be provided at the bottom of the material rack to facilitate the movement of the material rack. After the feeding conveyor line 43 obtains the shell material preparation assembly 42 from the first material rack and transports it to the position corresponding to the shell material feeding mechanism 41, the first material rack can be separated from the loading position, and then the second material rack can be moved to the loading position. The second material rack is placed with a shell material preparation assembly 42 containing shell materials. After the shell material on the shell material preparation assembly 42 transported from the first material rack to the feeding conveyor line 43 is used up, the moving mechanism moves the shell material preparation assembly 42 to one side of the feeding conveyor line 43, so that the feeding conveyor line 43 can obtain the shell material preparation assembly 42 from the second material rack and transport it to the loading position, which is conducive to improving production efficiency.

[0108] In some embodiments of the present disclosure, please refer to Figures 1, 4 and 5. The feed conveyor line 43 is a feed roller, and there is a first interval between two adjacent rollers of the feed roller along the length direction b of the feed roller; the moving mechanism is arranged corresponding to the first interval, so that along the height direction of the feed roller, the moving mechanism can pass through the first interval to lift the shell material preparation assembly 42 from the feed roller.

[0109] By enabling the moving mechanism to pass through the first interval to lift the shell material preparation assembly 42 from the feed roller, the moving mechanism can support the shell material preparation assembly 42 in the middle of the length direction b of the feed roller to lift the shell material preparation assembly 42 from the feed roller, and the supporting effect of the moving mechanism on the shell material preparation assembly 42 is relatively stable.

[0110] In some embodiments of the present disclosure, referring to Figures 1, 4, and 5, there may be multiple transport mechanisms, each corresponding to a plurality of first intervals. This helps improve the stability of the transport mechanisms in supporting the shell material preparation assembly 42. In some embodiments of the present disclosure, the multiple transport mechanisms may be provided in a one-to-one correspondence with the plurality of first intervals.

[0111] In some embodiments of the present disclosure, please refer to Figures 1, 4 and 5. The first interval passes through the first side of the feed roller along the width direction c of the feed roller; the shell material conveying submodule 4 also includes a discharging roller 44, and there is a second interval between the adjacent rollers of the discharging roller 44 along the discharging direction. The second interval passes through the first side of the discharging roller 44 along the width direction of the discharging roller 44, so that the moving mechanism can move from the first interval to the second interval through the first side of the feed roller and the first side of the discharging roller 44, so as to drive the shell material preparation assembly 42 from the feed roller to the discharging roller 44, so that the discharging roller 44 conveys the shell material preparation assembly 42 to the discharging bracket.

[0112] In the embodiment of the present disclosure, the moving mechanism can move from the first interval to the second interval through the first side of the feed roller and the first side of the discharging roller 44, so as to drive the shell material preparation assembly 42 from the feed roller to the discharging roller 44. This means that the moving mechanism can first move along the width direction c of the feed roller, that is, along the axial direction of the roller of the feed roller, while maintaining the extended state, so as to pass through the first side of the feed roller along the width direction c of the feed roller and move to one side of the feed roller; thereafter, the moving mechanism can move along the width direction of the discharging roller 44 while maintaining the extended state, so as to pass through the first side of the discharging roller 44 along the width direction of the discharging roller 44 and move to the second interval; finally, the moving mechanism is changed from the extended state to the retracted state, the moving mechanism falls, and the shell material preparation assembly 42 falls to the upper side of the discharging roller 44, so that the discharging roller 44 can transport the shell material preparation assembly 42.

[0113] By having the transport mechanism drive the shell material preparation assembly 42 away from the feed roller conveyor through the first side of the feed roller conveyor, the shell material preparation assembly 42 can be moved more conveniently. By having the transport mechanism move through the first side of the discharge roller conveyor 44 to the second interval to drive the shell material preparation assembly 42 from the feed roller conveyor to the discharge roller conveyor 44, when the transport mechanism places the shell material preparation assembly 42 on the discharge roller conveyor 44, the discharge roller conveyor 44 has a larger support area for the shell material preparation assembly 42, making the discharge roller conveyor 44 more stable in supporting the shell material preparation assembly 42.

[0114] In some embodiments of the present disclosure, referring to Figures 1, 4, and 5, there may be multiple transfer mechanisms, each of which is provided for each of the multiple first intervals. There may also be multiple second intervals, each of which corresponds one-to-one with the multiple first intervals. The corresponding transfer mechanism is configured to move through the first side of the corresponding first interval and the first side of the corresponding second interval into the corresponding second interval. This facilitates smooth movement of the shell material preparation assembly 42 during its transfer.

[0115] In some embodiments of the present disclosure, please refer to Figures 1, 4 and 5, the first interval passes through the first side of the feed roller along the width direction c of the feed roller; the shell material conveying submodule 4 also includes a discharge roller 44, and there is a second interval between adjacent rollers of the discharge roller 44 along the discharge direction, and the second interval passes through the first side of the discharge roller 44 along the width direction of the discharge roller 44; the moving mechanism includes a lifting member and a moving conveyor line arranged at the top end of the lifting member, when the moving mechanism is in an extended state, one end of the lifting member is located in the first interval, and the other end extends through the first side of the feed roller and the first side of the discharge roller 44 to the second interval; the extension path of the moving conveyor line matches the extension path of the lifting member, so that the moving conveyor line can move from the feed roller to the discharge roller, so that the discharge roller 44 can convey the shell material preparation assembly 42 to the discharge bracket.

[0116] The black arrow in Figure 4 indicates the direction of movement of the shell material preparation assembly 42 driven by the feed roller, the transfer mechanism, and the discharge roller 44. Driven by the feed roller, the shell material preparation assembly 42 moves from the feed position to the position corresponding to the shell material feeding mechanism 41, then moves to the discharge roller 44 driven by the transfer mechanism, and then moves to the discharge roller 44 driven by the discharge roller 44 to the discharge position.

[0117] By extending the lifting member through the first side of the feed roller to one side of the feed roller, the transporting conveyor line provided on the lifting member can transport the shell material preparation assembly 42 to one side of the feed roller along the width direction c of the feed roller, which is relatively convenient to implement. By extending the lifting member through the first side of the discharge roller 44 to the second interval of the discharge roller 44, the transporting conveyor line provided on the lifting member can transport the shell material preparation assembly 42 to the discharge roller 44 along the width direction of the discharge roller 44, which is relatively convenient to implement. Moreover, when the transporting mechanism places the shell material preparation assembly 42 on the discharge roller 44, the support area of ​​the discharge roller 44 for the shell material preparation assembly 42 is relatively large, making the support of the discharge roller 44 for the shell material preparation assembly 42 relatively stable.

[0118] In some embodiments of the present disclosure, referring to Figures 1, 4, and 5, there can be multiple transfer mechanisms, each corresponding to a plurality of first intervals. There can also be multiple second intervals, each corresponding to a plurality of first intervals. When the transfer mechanism is in the extended state, it extends from the corresponding first interval into the corresponding second interval through the first side of the corresponding first interval and the first side of the corresponding second interval. This helps improve the smoothness of movement of the shell material preparation assembly 42 during transfer.

[0119] In some embodiments of the present disclosure, referring to FIG. 1 , FIG. 4 and FIG. 5 , the discharge roller 44 and the feed roller are arranged along the width direction c of the feed roller.

[0120] By arranging the discharge roller 44 and the feed roller along the width direction c of the feed roller, the moving mechanism only needs to drive the shell material preparation assembly 42 along the width direction of the discharge roller 44 to transport the shell material preparation assembly 42 to the discharge roller 44, which is more convenient to implement.

[0121] In some embodiments of the present disclosure, referring to FIG. 1 , FIG. 4 and FIG. 5 , the width direction of the discharge roller 44 is parallel to the width direction c of the feed roller.

[0122] By making the width direction of the discharge roller 44 parallel to the width direction c of the feed roller, the shell material preparation assembly 42 does not need to have a large bend in the movement path when moving from the feed roller to the discharge roller 44, which is more convenient to implement.

[0123] In some embodiments of the present disclosure, referring to Figures 1, 4 and 5, the discharge roller 44 includes a first roller and a second roller, and the first roller and the second roller form a first interval; the discharge roller 44 includes a third roller and a fourth roller, and the third roller and the fourth roller form a second interval; along the length direction b of the feed roller, the first roller is flush with the third roller, and the second roller is flush with the fourth roller.

[0124] By making the first roller flush with the third roller and the second roller flush with the fourth roller along the length direction b of the feed roller, the part of the moving mechanism supporting the shell material preparation assembly 42 only needs to move along the width direction of the discharge roller 44 to transport the shell material preparation assembly 42 to the discharge roller 44, which is more convenient to implement.

[0125] In some embodiments of the present disclosure, referring to FIG. 1 , FIG. 4 and FIG. 5 , the height direction of the discharge roller 44 is parallel to the height direction of the feed roller.

[0126] By making the height direction of the discharge roller 44 parallel to the height direction of the feed roller, the posture of the shell material preparation assembly 42 does not need to change significantly during the process of transferring the shell material preparation assembly 42 from the feed roller 44. The discharge roller 44 can provide relatively stable support for the shell material preparation assembly 42, which is conducive to making it easier for the moving mechanism to move the shell material preparation assembly 42.

[0127] In some embodiments of the present disclosure, referring to Figures 1, 4, and 5, the discharge roller 44 is aligned with the feed roller in height, which helps save space occupied by the discharge roller 44 and the feed roller and facilitates the movement of the movement mechanism.

[0128] In some embodiments of the present disclosure, please refer to Figures 1 and 6. The coating material conveying module includes an adhesive material conveying sub-module 5, and the adhesive material conveying sub-module 5 includes an adhesive material feeding mechanism and at least two adhesive material preparation components 51. The adhesive material feeding mechanism is used to obtain adhesive materials from at least two adhesive material preparation components 51 for conveying.

All adhesive material preparation assemblies 51 in the embodiments of the present disclosure are used to accommodate adhesive, which is a type of coating material. In some embodiments of the present disclosure, the adhesive may be blue glue.

[0131] By making the adhesive feeding mechanism obtain adhesive from at least two adhesive preparation assemblies for transportation respectively, when the adhesive feeding mechanism obtains adhesive from one adhesive preparation assembly for transportation, the other adhesive preparation assemblies are in an idle state, which is convenient for replenishment. In this way, when the bare cell shelling production line is running, at least one of all the adhesive preparation assemblies contains adhesive, the adhesive feeding mechanism can always obtain adhesive for transportation, and the bare cell shelling production line does not need to be shut down when the adhesive on one adhesive preparation assembly is used up, which is conducive to improving production efficiency.

[0132] In some embodiments of the present disclosure, please refer to Figures 1 and 6. The adhesive feeding mechanism includes a second frame 52 and an adhesive picking component 53. The second frame 52 is relatively fixed to at least two adhesive preparation components 51.

[0133] By fixing the second frame 52 relative to at least two adhesive material preparation assemblies, the adhesive material picking part moves relative to the second frame 52 to positions corresponding to at least two adhesive material preparation assemblies to obtain adhesive for transportation.

[0135] The second direction d in the embodiment of the present disclosure may extend along a straight line, or may not extend along a straight line, such as extending along a curve or a broken line.

[0136] By making the second frame 52 span between at least two adhesive material preparation assemblies along the second direction d, the adhesive material picking part slides relative to the second frame 52 along the second direction d to move to a position corresponding to the at least two adhesive material preparation assemblies, which helps to make the structure of the feeding mechanism simpler and more convenient to implement.

[0137] In some embodiments of the present disclosure, please refer to Figures 1 and 6. The adhesive feeding mechanism also includes a bonding robot, which is slidably connected to the second frame 52 along the second direction d.
