Description

Technical Field

[0001] This utility model relates to the field of battery production technology, and in particular to a battery production line. Background Technology

[0002] Currently, rechargeable batteries are widely used in electronic devices, vehicles, aircraft, and other equipment. Rechargeable batteries can be divided into hard-case batteries and pouch batteries. Pouch batteries generally consist of an air bag and the battery cells housed within it. During the production of pouch batteries, after the battery cells are inserted into the air bag, the bag opening needs to be opened to inject electrolyte, allowing the pouch battery to complete its formation process. In related technologies, during the air bag flaring process, the air bag may experience tearing, wrinkling, or other damage. Therefore, reducing the breakage rate of the air bag due to flaring has become a technical problem to be solved. Utility Model Content

[0003] This utility model provides a battery production line.

[0004] The battery production line according to the embodiments of this application includes a conveying device, a preheating device, and a flaring device.

[0005] The conveying device includes a conveyor belt for conveying pouch batteries; the preheating device is located upstream of the flaring device for preheating and softening the air bag of the pouch battery, and the flaring device is used to flare the softened air bag.

[0006] In the battery production line of this application, a conveying device transports pouch batteries to a preheating device via a conveyor belt along a specific path. The preheating device preheats and softens the gas bags of the pouch batteries. The preheated and softened gas bags are then conveyed by the conveying device to a flaring device, where the top of the gas bag is flared out under the action of the flaring device. Because the gas bags of the pouch batteries are preheated and softened, the flexibility of the gas bags is increased, making them less prone to breakage during the flaring process, thus reducing the breakage rate caused by the flaring of the pouch batteries.

[0007] In some embodiments, the preheating device includes a housing and a heating element disposed within the housing, the housing having an air outlet configured to face the air bag.

[0008] In the above embodiment, the outer casing of the preheating device protects and supports the device. The preheating function is achieved by a heating element inside the device. The heated gas generated by the internal heating element is blown out through an air outlet on the outer casing, which faces the surface of the pouch battery's air bag. This configuration results in a more concentrated airflow and higher heating efficiency, enabling efficient preheating at a lower cost.

[0009] In some embodiments, the preheating devices are arranged on both sides of the conveyor belt in the width direction, and the air outlets of the preheating devices located on both sides of the conveyor belt are aligned.

[0010] In the above embodiment, the preheating device is located on both sides of the conveyor belt width direction, which can preheat both sides of the soft-pack battery air bag at the same time. The air outlets on both sides are aligned, so that the preheating device can heat the same position on both sides of the battery air bag, ensuring that the same position on both sides of the soft-pack battery air bag has the same temperature difference with the environment, ensuring that the same position achieves the same preheating result, preventing different local deformation caused by different heating positions from affecting subsequent processing, and ensuring the flaring quality.

[0011] In some embodiments, the flaring device includes at least two first flaring mechanisms arranged in pairs along both sides of the width direction of the conveyor belt. Each first flaring mechanism includes an adsorption element and a first driving element. One end of the adsorption element is configured to adsorb onto the air bag. The first driving element is used to drive the adsorption element to move along both sides of the conveyor belt so that the adsorption element pulls open the opening of the air bag.

[0012] In the above embodiment, the flaring device flares the air bag after it has been preheated by the preheating device. Driven by the first driving member, the adsorption member contacts one side of the air bag and adsorbs one side of the air bag. The first driving member drives the adsorption member to move along the thickness direction of the air bag, and the surface of the air bag adsorbed by the adsorption member also moves accordingly. At least two first flaring mechanisms are arranged in pairs, aligned on both sides of the conveyor belt width direction, which can simultaneously adsorb both sides of the air bag. Multiple pairs of first flaring mechanisms can simultaneously open multiple air bags, greatly improving the working efficiency of the first flaring mechanism. In addition, the conveying device, preheating device, and flaring device are concentrated on the same production line, which is beneficial to improving production efficiency and speeding up the production line cycle.

[0013] In some embodiments, the first flaring mechanism further includes a mounting plate on which the adsorption member is mounted, and the first driving member is connected to the mounting plate to drive the adsorption member to move via the mounting plate.

[0014] In the above embodiment, the adsorption element is connected to the mounting plate, and the mounting plate is connected to the first driving element. The first driving element drives the mounting plate to move, thereby causing the adsorption element mounted on the mounting plate to move. Through the action of the mounting plate, the height of the adsorption element can be easily adjusted to a suitable position, allowing the adsorption of pouch batteries of different sizes to be used with the same adsorption element, thus improving the practicality of the adsorption element.

[0015] In some embodiments, the mounting plate is slidably fitted onto the adsorption member, and the first flaring mechanism further includes an elastic member connecting the adsorption member and the mounting plate, the elastic member being used to absorb a force greater than a threshold applied to the mounting plate by the first driving member.

[0016] In the above embodiment, the mounting plate can be slidably sleeved on the adsorption member and can move horizontally in the axial direction of the adsorption member. At this time, under the action of the mounting plate, the elastic member located between the adsorption member and the mounting plate deforms. The elastic member can absorb the force output from the first driving member that is greater than the force required for the adsorption member to adsorb the soft pack battery, thereby ensuring that the force acting on the adsorption member is within a reasonable range, ensuring the adsorption effect of the adsorption member, and preventing excessive force from damaging the soft pack battery and reducing the breakage rate of the soft pack battery.

[0017] In some embodiments, the flaring device further includes a second flaring mechanism, which includes at least a pair of flaring members, a second driving member, and a third driving member. The second driving member is used to drive the pair of flaring members to insert into or remove from the air bag after the bag opening is pulled open. The third driving member is used to drive the pair of flaring members to move away from each other along the edge of the bag opening to widen the bag opening.

[0018] In the above embodiment, after the air bag of the soft-pack battery is drawn open by the adsorption member to form a bag opening, the opening is then further expanded under the action of the second expanding mechanism of the expanding device. The second driving member acting on the second expanding mechanism is used to drive at least one pair of expanding members to move downward or upward. When the second expanding mechanism moves downward, the expanding members extend from top to bottom through the bag opening of the soft-pack battery, and the expanding members begin to expand the bag opening.

[0019] The third driving member, also acting on the second flaring mechanism, drives at least one pair of flaring members to move in opposite directions along the edge of the pouch opening after the second driving member inserts the flaring member into the pouch opening. When at least one pair of flaring members reaches a designated position, the entire pouch opening is fully enlarged. The flaring member can then be removed from the pouch opening under the action of the second driving member, thus completing the flaring of the pouch opening. In this way, the pouch battery only needs the coordination of the different movements of the two flaring mechanisms to complete the flaring, and the flaring efficiency and quality are significantly improved.

[0020] In some embodiments, the second flaring mechanism further includes a fixing member, at least one of the flaring members being slidably disposed on the fixing member, the second driving member being connected to the fixing member, and the third driving member being mounted on the fixing member.

[0021] In the above embodiment, the second driving member drives the flared member connected to the fixed member to move up and down with the fixed member. Only the movement of the fixed member needs to be controlled to perform the same control on multiple pairs of flared members arranged on the fixed member. This allows multiple pairs of flared members to contact multiple pouch batteries at the same time, which greatly improves the efficiency of the flaring device. The third driving member is installed on the fixed member, which makes the fixed member highly integrated. The driving member can control the flared members within a minimal space, which helps to reduce the overall size of the flaring device.

[0022] In some embodiments, at least one pair of the flaring members is disposed between the two first flaring mechanisms.

[0023] In the above embodiments, the flaring component is arranged between the first flaring mechanisms. The flaring component and the first flaring mechanism are located in the same working space. The arrangement of the first flaring mechanism and the second flaring mechanism on the battery production line is compact, which is conducive to improving the flaring efficiency of the flaring device. At the same time, it also makes the overall volume of the flaring device smaller, and can realize the flaring of the air bag in a small space.

[0024] In some embodiments, the flaring device includes a first mounting base, a second mounting base, a column, and an adjustment mechanism. The first flaring mechanism and the second flaring mechanism are mounted on the first mounting base. The first mounting base is movably mounted on the column. The second mounting base is fixedly connected to the column. The adjustment mechanism is mounted on the second mounting base and connected to the first mounting base. The adjustment mechanism is used to adjust the height of the first mounting base to adjust the height of the first flaring mechanism and the second flaring mechanism.

[0025] In the above embodiment, the first flaring mechanism and the second flaring mechanism are respectively connected to the first mounting base and remain relatively stationary. When the first mounting base moves upward or downward, the first flaring mechanism and the second flaring mechanism move by the same displacement in the same direction. Thus, the entire flaring mechanism can be adjusted simply by adjusting the first mounting base, which is convenient to operate, and the adjustment is quick and accurate, thus improving the overall working efficiency of the device.

[0026] The first mounting base and the second mounting base are connected by a column. The second mounting base is fixed to the top of the column and cannot move relative to the column. The first mounting base can move up and down through the column it is connected to, thereby changing the height of the first and second flaring mechanisms. The column connection has low cost, simple structure, and can achieve height adjustment in a short time.

[0027] The adjustment mechanism is located on the second mounting base and connected to the first mounting base. The relative position of the first mounting base and the second mounting base can be adjusted by the adjustment mechanism. By raising or lowering the height of the first mounting base, the adjustment mechanism can adjust the height of the first flaring mechanism and the second flaring mechanism, which can accommodate soft-pack batteries of different specifications and has a wider range of applications.

[0028] In some embodiments, the adjusting mechanism includes a screw and a handle, the screw passing through the second mounting base and connected to the first mounting base, and the handle being connected to one end of the screw.

[0029] In the above embodiment, the handle is located on the upper surface of the second mounting base, and the screw passes through the second mounting base and is connected to the first mounting base. The rotation of the handle can drive the rotation of the screw of the adjustment mechanism. The screw drives the first mounting base to move up or down through the rotation of the first mounting base in the threaded hole, thereby realizing the height adjustment of the first mounting base and changing the overall height of the flaring device. The screw and handle work together to make the adjustment mechanism easier to implement and lower in cost.

[0030] In some embodiments, the battery production line further includes a support and positioning device disposed on the conveyor belt, the support and positioning device having a positioning groove for loading the pouch battery.

[0031] In the above embodiment, the support positioning devices on the conveyor belt are evenly arranged on the surface of the conveyor belt. Each support positioning device can hold a pouch battery. The positioning groove of the support positioning device is the direct contact position of the pouch battery on the support positioning device. The pouch battery can be positioned correctly on the support positioning device through the simple structure of the positioning groove, which ensures the correct flaring position of the pouch battery in the future.

[0032] In some embodiments, the battery production line further includes a clamping device disposed on the conveying device, the clamping device including a jaw and a fourth driving member connected to the jaw, the fourth driving member being used to drive the jaw to open and close to clamp the pouch battery.

[0033] In the above embodiment, the fourth driving member of the clamping device is connected to the gripper. When the pouch battery is about to be conveyed to the flaring device by the conveying device, the gripper contacts the bottom end of the pouch battery under the driving action of the fourth driving member, and the pouch battery is fixed by clamping the gripper. When the pouch battery completes the flaring and leaves the flaring device, the gripper opens to release the fixation of the pouch battery. In this way, the clamping device uses the gripper to clamp and fix the pouch battery, which has a simple structure and facilitates the flaring device to flare.

[0051] Please refer to Figure 1 , Figure 1 This is a partial perspective view of a battery production line 100 according to an embodiment of the present invention. The battery production line 100 according to this application includes a conveying device 10, a preheating device 20, and a flaring device 30.

[0052] The conveying device 10 includes a conveyor belt 11 for conveying the soft-pack battery 200; a preheating device 20 is located upstream of the flaring device 30, the preheating device 20 preheats and softens the air bag 201 of the soft-pack battery 200, and the flaring device 30 is used to flare the softened air bag 201.

[0053] In the battery production line 100 of this application embodiment, the conveying device 10 conveys the pouch battery 200 to the preheating device 20 via the conveyor belt 11 through a specific path. The preheating device 20 preheats and softens the air bag 201 of the pouch battery 200. The preheated and softened air bag 201 is then conveyed by the conveying device 10 to the flaring device 30. Under the action of the flaring device 30, the top of the softened air bag 201 is flared. Because the air bag 201 of the pouch battery 200 is preheated and softened, the flexibility of the air bag 201 is increased, making it less prone to breakage during the flaring process, thus reducing the breakage rate caused by the flaring of the pouch battery 200. In addition, the conveying device, preheating device, and flaring device are concentrated on the same production line, which is beneficial to improving production efficiency and speeding up the production line cycle.

[0054] Specifically, the conveying device 10 is a device that uses its internal mechanical components to move materials from one position to another. In some embodiments of this application, the conveying device 10 is a key component for conveying the pouch batteries 200. The pouch batteries 200 are placed on the surface of the conveyor belt 11, and each pouch battery 200 on the conveyor belt 11 is fixedly connected to a certain position on the conveyor belt 11. The pouch batteries 200 move along a specific path, namely the movement path of the conveying device 10, on the battery production line 100, thereby realizing the conveying of the pouch batteries 200 on the battery production line 100.

[0055] The preheating device 20 is an auxiliary device that preheats the pouch battery 200 to the required operating temperature before it enters the flaring process. In some embodiments of this application, the pouch battery 200 is preheated before flaring. After the pouch battery 200 is heated by the preheating device 20 for a certain period of time, the surface temperature of the pouch battery 200 reaches a preset temperature, and the air bag 201 of the pouch battery 200 gradually softens as its surface temperature rises.

[0056] The softened air bag 201 has improved extensibility, making it more flexible and able to withstand greater deformation without tearing. The wrinkles on the surface caused by external forces are also smoother, which helps reduce the damage to the soft-pack battery 200 and improves the quality of the flare.

[0057] In some embodiments of this application, the flaring device 30 achieves the flaring purpose at room temperature by using mechanical pressure and utilizing the movement of key components within the flaring device 30 in a specific direction or along a specific path. The pouch battery 200 is conveyed to the preheating device 20 via the conveying device 10. After the pouch battery 200 is softened by the preheating device 20, it is then conveyed to the flaring device 30 via the conveying device 10. The flaring device 30 flares open the top edge of the air pocket 201 of the pouch battery 200 to complete the flaring.

[0058] Please refer to Figure 1 and Figure 2 ,in, Figure 2 This is a perspective view of the preheating device 20 according to an embodiment of the present invention. In some embodiments, the preheating device 20 includes a housing 21 and a heating element 22 disposed within the housing 21. The housing 21 is provided with an air outlet 23, which is configured to face the air bag 201.

[0059] In the above embodiment, the outer casing 21 of the preheating device 20 protects and supports the preheating device 20. The preheating function is achieved by the heating element 22 inside the preheating device 20. The heated gas generated by the internal heating element 22 is blown out through the air outlet 23 on the outer casing 21, and the air outlet 23 is oriented towards the surface of the air bag 201 of the soft-pack battery 200. The preheating device 20 configured in this way has a more concentrated air outlet, high heating efficiency, and can achieve efficient preheating at a lower cost.

[0060] Specifically, the function of the outer casing 21 involves protecting and supporting the internal components, and it needs to possess both safety and aesthetic characteristics. In some embodiments of this application, the outer casing 21 of the preheating device 20 can be formed by bending a metal plate through a specific process, creating a robust cover-like outer casing 21 around the heating element 22. This effectively prevents external objects from directly impacting the internal components and prevents the intrusion of foreign objects from causing localized overheating of the heating element 22. In addition, mounting bosses can be provided inside the outer casing 21 to fix the internal components and prevent them from loosening, falling off, or being damaged due to vibration.

[0061] The internal heating element 22 of the preheating device 20 is the core component for achieving the preheating function. In some embodiments of this application, the preheating device 20 can be a hot air type preheating device, and the heating element 22 can be in the form of an electric heating tube or an electric heating wire, converting electrical energy into heat energy to achieve the heating function.

[0062] The hot air generated on the preheating device 20 can be centrally transported to the air outlet 23 through the air duct. The air outlet 23 is positioned facing the air bag 201 to ensure direct contact between the hot air and the air bag 201, thereby preheating the air bag 201. The pouch battery 200 is conveyed to the preheating device 20 via the conveying device 10 and comes into contact with the hot air blown out of the air outlet 23 of the preheating device 20. At a higher temperature, the surface temperature of the air bag 201 of the pouch battery 200 rises, realizing the preheating and softening function of the air bag 201 of the pouch battery 200 by the preheating device 20.

[0063] Please refer to again Figure 1 In some embodiments, preheating devices 20 are arranged on both sides of the conveyor belt 11 in the width direction, and the air outlets 23 of the preheating devices 20 located on both sides of the conveyor belt 11 are aligned.

[0064] In the above embodiment, the preheating device 20 is located on both sides of the conveyor belt 11 in the width direction, and can preheat both sides of the soft-pack battery 200 air bag 201 at the same time. The air outlets 23 on both sides are aligned, so that the preheating device 20 can heat the same position on both sides of the battery air bag 201, ensuring that the same position achieves the same preheating result.

[0065] Specifically, the preheating devices 20 located on both sides of the conveyor belt 11 in the width direction are arranged face to face, that is, the air outlets 23 are arranged opposite each other, which ensures that the hot air generated by the preheating devices 20 acts on the same spatial position simultaneously. When the pouch battery 200 is conveyed to the position of the preheating device 20 by the conveyor device 10, the hot air can be blown evenly onto the two surfaces of the air bag 201, ensuring that the same position on both sides of the pouch battery 200 air bag 201 has the same temperature difference with the gas environment, ensuring that the surface of the air bag 201 is heated to the same degree, preventing different local deformations caused by different heating positions from affecting subsequent processing, and ensuring the quality of preheating.

[0066] Please refer to Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the flaring device 30 of this utility model. Figure 4 This is a schematic diagram of the structure of the first flaring mechanism 31 of this utility model. In some embodiments, the flaring device 30 includes at least two first flaring mechanisms 31, which are arranged in pairs along both sides of the width direction of the conveyor belt 11. Each first flaring mechanism 31 includes an adsorption member 311 and a first driving member 312. One end of the adsorption member 311 is configured to adsorb onto the air bag 201, and the first driving member 312 is used to drive the adsorption member 311 to move along both sides of the conveyor belt 11 so that the adsorption member 311 pulls open the opening of the air bag 201.

[0067] In the above embodiment, the flaring device 30 flares the air bag 201, which has been preheated by the preheating device 20. Driven by the first driving member 312, the adsorption member 311 contacts one side surface of the air bag 201 and adsorbs one side of the air bag 201. The first driving member 312 drives the adsorption member 311 to move along the thickness direction of the air bag 201, and the surface of the air bag 201 adsorbed by the adsorption member 311 also moves accordingly. At least two first flaring mechanisms 31 are arranged in pairs on both sides of the width direction of the conveyor belt 11, which can simultaneously adsorb both sides of the air bag 201. Multiple pairs of first flaring mechanisms 31 can simultaneously open multiple air bags 201, greatly improving the working efficiency of the first flaring mechanism 31.

[0068] Specifically, the adsorption component 311 is a functional part in a mechanical device that uses the generated adsorption force to grasp and fix a moving object. In some embodiments of this application, the adsorption component 311 located on the first flaring mechanism 31 can be a component with a suction cup structure. The opening on the large diameter side of the suction cup of the adsorption component 311 is in close contact with the side of the air bag 201 of the soft-pack battery 200. By evacuating the air between the suction cup and the air bag 201, atmospheric pressure can be used to generate an adsorption force, thereby firmly attaching the suction cup to the air bag 201.

[0069] The first driving element 312 is a component that receives external energy and converts it into mechanical energy, thereby providing initial power and movement to the adsorption element 311. In some embodiments of this application, the first driving element 312 may be a cylinder-type driving element, which uses the energy of compressed air to drive the energy output end to perform linear reciprocating motion in the horizontal direction in a direction perpendicular to the surface of the air bag 201, providing energy to the adsorption element 311 and causing the adsorption element 311 to move away from or closer to the soft-pack battery 200 located on the conveying device 10.

[0070] In some embodiments of this application, the first flaring mechanism 31 is arranged in pairs along both sides of the width direction of the conveyor belt 11. This ensures that the first flaring mechanism 31 acts on both surfaces of the air bag 201 of the soft-pack battery 200 at the same time. This ensures that when the flaring mechanism opens the bag opening, the two surfaces of the air bag 201 are subjected to equal and opposite forces at the same time. This ensures that the air bag 201 forms a symmetrical deformation along the outer edge of the top of the soft-pack battery 200, and ensures that the shape of each bag opening has a certain regularity and uniformity, which is beneficial for subsequent flaring.

[0071] Please refer to again Figure 4 In some embodiments, the first flaring mechanism 31 further includes a mounting plate 313, the adsorption member 311 is mounted on the mounting plate 313, and the first driving member 312 is connected to the mounting plate 313 to drive the adsorption member 311 to move through the mounting plate 313.

[0072] In the above embodiment, the adsorption member 311 is connected to the mounting plate 313, and the mounting plate 313 is connected to the first driving member 312. The first driving member 312 drives the mounting plate 313 to move, thereby driving the adsorption member 311 mounted on the mounting plate 313 to move. Through the action of the mounting plate 313, the height position of the adsorption member 311 can be easily adjusted to a suitable position, and soft-pack batteries 200 of different specifications and sizes can be adsorbed under the premise of using the same adsorption member 311, which improves the practicality of the adsorption member 311.

[0073] Specifically, the mounting plate 313 is a component connected between the first driving member 312 and the adsorption member 311. A groove can be provided on the surface of the mounting plate 313 that contacts the adsorption member 311. The adsorption member 311 has a cuboid protrusion. The length direction of the protrusion is perpendicular to the movement direction of the adsorption member 311. The width of the groove is slightly larger than the width of the cuboid protrusion on the adsorption member 311. The cuboid protrusion can be installed in the groove. The two can be fixed by the locking mechanism through the cooperation of the hole on the protrusion and the groove.

[0074] The mounting plate 313 is fixed in place, while the mounting plate 313 and the adsorption component 311 can slide relative to each other. That is, the protrusion can slide in the groove. The up and down sliding of the protrusion relative to the groove on the mounting plate 313 can drive the overall up and down movement of the adsorption component 311, thereby changing the relative position of the adsorption component 311 and the mounting plate 313, so that the overall height of the adsorption component 311 can be adjusted. This is used to adsorb soft-pack batteries 200 of different specifications and sizes, improving the compatibility between the flaring device 30 and the soft-pack battery 200.

[0075] Please refer to again Figure 4 In some embodiments, the mounting plate 313 can be slidably fitted onto the adsorption member 311. The first flaring mechanism 31 also includes an elastic member 314 connecting the adsorption member 311 and the mounting plate 313. The elastic member 314 is used to absorb the force greater than a threshold applied to the mounting plate 313 by the first driving member 312.

[0076] In the above embodiment, the mounting plate 313 can be slidably sleeved on the adsorption member 311 and can move horizontally in the axial direction of the adsorption member 311. At this time, under the action of the mounting plate 313, the elastic member 314 located between the adsorption member 311 and the mounting plate 313 deforms. The elastic member 314 can absorb the force output from the first driving member 312, which is more than the force required for the adsorption member 311 to adsorb the soft pack battery 200. This ensures that the force acting on the adsorption member 311 is within a reasonable range, ensures the adsorption effect of the adsorption member 311, and prevents excessive force from damaging the soft pack battery 200, thereby reducing the breakage rate of the soft pack battery 200.

[0077] Specifically, the driving force from the first driving member 312 can be transmitted to the adsorption member 311 through the mounting plate 313, thereby providing energy for the movement of the adsorption member 311. The driving member can directly contact the mounting plate 313 through its energy output end, and the energy from the driving member drives the mounting plate 313, that is, the component connected to the adsorption member 311, to move horizontally.

[0078] When the energy output component of the first driving member 312 moves toward the soft-pack battery 200 to its maximum position, the adsorption member 311 is driven to contact the surface of the air bag 201 of the soft-pack battery 200, and the adsorption member 311 adsorbs the surface of the air bag 201; when the energy output component of the first driving member 312 moves away from the soft-pack battery 200, the adsorption member 311 no longer contacts the surface of the air bag 201 of the soft-pack battery 200, and the adsorption member 311 releases its adsorption.

[0079] In some embodiments of this application, the mounting plate 313 and the adsorption member 311 can be connected by an elastic member 314. The elastic member 314 is a component with significant elastic deformation capability, which can deform under the action of external force and completely restore its original shape and size when the external force is removed. Exemplarily, the elastic member 314 can be a spring.

[0080] The first driving member 312 drives the mounting plate 313 to move the adsorption member 311. When the driving force applied to the mounting plate 313 is too large, the force transmitted from the mounting plate 313 to the adsorption member 311 will also exceed its threshold. At this time, the elastic member 314 located between the mounting plate 313 and the adsorption member 311 can absorb kinetic energy by deforming the elastic material, temporarily storing the force exceeding the threshold as elastic potential energy, and releasing it when the elastic member 314 recovers its deformation.

[0081] In this way, the adsorption force exerted by the adsorption element 311 on the soft-pack battery 200 is less than its threshold, and the soft-pack battery 200 will not be damaged by the excessive force exerted by the adsorption element 311, thus ensuring the functional realization of the first flaring mechanism 31.

[0082] Please refer to Figure 5 , Figure 5 This is a perspective view of the second flaring mechanism 32 of the present invention. In some embodiments, the flaring device 30 further includes a second flaring mechanism 32, which includes at least a pair of flaring members 321, a second driving member 322, and a third driving member 323. The second driving member 322 is used to drive the pair of flaring members 321 to insert into or remove from the air bag 201 after the bag opening of the air bag 201 is opened. The third driving member 323 is used to drive the pair of flaring members 321 to move away from each other along the edge of the bag opening to widen the bag opening.

[0083] In the above embodiment, after the air bag 201 of the soft-pack battery 200 is drawn open by the adsorption member 311, it forms a bag opening. Then, under the action of the second widening mechanism 32 of the widening device 30, the widening continues to be completed. The second driving member 322 acting on the second widening mechanism 32 is used to drive at least one pair of widening members 321 to move downward or upward. When the second widening mechanism 32 moves downward, the widening members 321 extend from top to bottom into the bag opening of the soft-pack battery 200, and the widening members 321 begin to expand the bag opening.

[0084] The third drive member 323, which also acts on the second flaring mechanism 32, drives at least one pair of flaring members 321 to move in opposite directions along the edge of the pouch opening after the second drive member 322 drives the flaring member 321 into the pouch opening of the pouch 200. When at least one pair of flaring members 321 moves to a designated position, the opening of the entire pouch 201 is fully enlarged. The flaring member 321 can then be removed from the pouch opening under the action of the second drive member 322, thus completing the flaring of the pouch opening of the pouch 200. In this way, the pouch 200 only needs to complete the flaring through the coordination of the different movements of the two flaring mechanisms, and the flaring efficiency and flaring quality are significantly improved.

[0085] Specifically, after the pouch battery 200 is acted upon by the first flaring mechanism 31, a pocket opening is formed. Then, the first flaring mechanism 31 releases contact with the pouch battery 200, and the position of the pouch battery 200 within the flaring device 30 remains unchanged. Next, the second flaring mechanism 32 completes the final flaring of the air pocket 201 of the pouch battery 200. In some embodiments of this application, the second flaring mechanism 32 includes at least one pair of flaring members 321. The portion of the flaring member 321 that acts on the air pocket 201 can be a sharp structure, with its vertical cross-section potentially being triangular, the sharp corner pointing towards the pocket opening of the pouch battery 200, and its horizontal cross-sectional area potentially increasing from bottom to top.

[0086] In this way, the strength of the flared part 321 can be guaranteed, and the flared part 321 in contact with the bag opening can complete the flaring with a small contact area at the contact position, thereby improving the flaring quality and reducing the potential damage to the soft-pack battery 200 during the flaring process.

[0087] The flared part 321 can be driven by the second driving part 322 to move in the vertical direction. In some embodiments of this application, the second driving part 322 can be the same as or similar to the first driving part 312. The second driving part 322 can be a cylinder-type driving part, which uses the energy of compressed air to drive the energy output end to perform linear reciprocating motion in the vertical direction along the vertical plane where the flared part 321 is located.

[0088] For example, the second driving member 322 can be connected to the connecting plate 325 located on the horizontal plane. The connecting post 326 is perpendicular to the horizontal plane. One end of the connecting post 326 is connected to the connecting plate, and the other end is fixed to the component where the flared member 321 is located. The end of the connecting post 326 is connected to the fixing member 324. By driving the connecting post 326 to move up and down through the second driving member 322, the fixing member 324 connected to it moves up and down accordingly, thereby driving the flared member 321 to move up and down, so that the flared member 321 moves away from or closer to the soft-pack battery 200 located on the conveying device 10, thereby allowing the flared member 321 to extend into or move out of the opened air bag 201, completing the first flaring action of the second flaring mechanism 32.

[0089] The flared part 321 can be driven by the third driving member 323 to move horizontally. In some embodiments of this application, the third driving member 323 is connected to the first connecting block 3241 located on the inner surface of the fixing member 324. The first connecting block 3241 is connected to the reciprocating motion plate 327 at a higher position to which the flared part is connected. The third driving member 323 can be the same as or similar to the first driving member 312. The third driving member 323 can be a cylinder-type driving member, which uses the energy of compressed air to drive the energy output end, thereby driving the reciprocating motion plate 327 connected to it to move back and forth in the horizontal direction, thereby driving the flared part 321 to move back and forth in the horizontal direction.

[0090] Please refer to Figure 6 , Figure 6 This is a partial perspective view of the second flaring mechanism 32 of this utility model. Exemplarily, a transmission device 328 can be provided between the reciprocating plates 327, and the transmission device 328 can be a rack and pinion transmission device. The third driving member 323 can be connected to the flaring member 321 through the transmission device 328 connected to the energy output end of the third driving member 323. The gear shaft of the gear 3281 is perpendicular to the movement direction of the third driving member 323 and is connected to the first connecting block 3241 driven by the third driving member 323. A rack 3282 is provided on the first connecting block 3241.

[0091] When the energy output end of the third drive member 323 moves horizontally perpendicular to the gear shaft, it can push the first connecting block 3241 to move back and forth in the horizontal direction, thereby driving the rack 3282 located on its surface to move back and forth, thus causing the flared part mounted on the reciprocating plate 327 at a higher position to move back and forth in the horizontal direction.

[0092] The meshing of gear 3281 and rack 3282 converts the movement of rack 3282 into the rotation of gear 3281. When gear 3281 rotates, it meshes with the second rack 3283 located on the second connecting block 3242, which in turn converts the rotation of gear 3281 into the movement of rack 3283, thereby causing the flared part mounted on the lower reciprocating plate 327 to move back and forth in the horizontal direction.

[0093] Due to the rotation of the gears, the meshing directions of the vertically opposite racks 3282 and 3283 with the gear 3281 are opposite. The racks 3282 and 3283 move in opposite directions, thereby driving at least one pair of flaring members 321 connected to the rack component to move in opposite directions. That is, the flaring members 321 move away from each other along the edge of the bag opening, completing the second flaring action of the second flaring mechanism 32.

[0094] Please refer to again Figure 5 In some embodiments, the second flaring mechanism 32 further includes a fixing member 324, at least one of the pair of flaring members 321 is slidably disposed on the fixing member 324, the second driving member 322 is connected to the fixing member 324, and the third driving member 323 is mounted on the fixing member 324.

[0095] In the above embodiment, the second driving member 322 drives the flared member 321 connected to the fixing member 324 to move up and down with the fixing member 324. Only the movement of the fixing member 324 needs to be controlled to perform the same control on multiple pairs of flared members 321 arranged on the fixing member 324, which enables multiple pairs of flared members 321 to contact multiple soft-pack batteries 200 at the same time, greatly improving the efficiency of the flaring device 30. The third driving member 323 is installed on the fixing member 324, which makes the fixing member 324 highly integrated. The driving member can control the flared member 321 within a minimal space, which is beneficial to control the overall size of the flaring device 30.

[0096] Specifically, the fixing member 324 is a component directly connected to the flaring member 321 on the second flaring mechanism 32. Under the action of the second driving member 322, the fixing member 324 drives the flaring member 321 to move accordingly. At least one of the pair of flaring members 321 can slide horizontally along the fixing member 324 in a direction perpendicular to the width direction of the conveyor belt 11 relative to the fixing member 324. The sliding flaring member 321 slides under the action of the third driving member 323, ensuring that the two flaring members 321 of the pair can move in opposite directions at the bag opening, thereby completing the flaring of the pouch bag 201 of the soft-pack battery 200. After the flaring is completed, the flaring member 321 located on the fixing member 324 continues to extend out of the flared air bag 201 under the action of the second driving member 322, preparing for the flaring of the next soft-pack battery 200.

[0097] Please refer to again Figure 3 In some embodiments, at least one pair of flaring elements 321 are disposed between two first flaring mechanisms 31.

[0098] In the above embodiment, the flaring component 321 is disposed between the first flaring mechanism 31. The flaring component 321 and the first flaring mechanism 31 are located in the same working space. The arrangement of the first flaring mechanism 31 and the second flaring mechanism 32 on the battery production line 100 is compact, which is conducive to improving the flaring efficiency of the flaring device 30. At the same time, it also makes the overall volume of the flaring device 30 smaller, so that the flaring of the air bag 201 can be achieved in a small space.

[0099] Specifically, the soft-pack battery 200 is located between the two first flaring mechanisms 31. After the air bag 201 of the soft-pack battery 200 is flared by the two first flaring mechanisms 31 to form an opening, it remains in this position waiting for the second flaring mechanism 32 to complete the flaring. At least one pair of flaring members 321 of the second flaring mechanism 32 are arranged between the two first flaring mechanisms 31, allowing the two flaring mechanisms to be arranged in a small space with a relatively compact layout. After the air bag 201 forms an opening, the flaring member 321 only needs to move downwards to insert into the opening. Then, the pair of flaring members 321 complete the flaring of the opening by moving back to back along the edge of the opening. The flaring member 321 does not need to move to the opening through other paths, which significantly improves the flaring efficiency.

[0100] Please refer to again Figure 3 In some embodiments, the flaring device 30 includes a first mounting base 33, a second mounting base 34, a column 35, and an adjustment mechanism 36. The first flaring mechanism 31 and the second flaring mechanism 32 are mounted on the first mounting base 33. The first mounting base 33 is movably mounted on the column 35. The second mounting base 34 is fixedly connected to the column 35. The adjustment mechanism 36 is mounted on the second mounting base 34 and connected to the first mounting base 33. The adjustment mechanism 36 is used to adjust the height of the first mounting base 33 to adjust the height of the first flaring mechanism 31 and the second flaring mechanism 32.

[0101] In the above embodiment, the first flaring mechanism 31 and the second flaring mechanism 32 are respectively connected to the first mounting base 33 and remain relatively stationary with respect to the first mounting base 33. When the first mounting base 33 moves upward or downward, the first flaring mechanism 31 and the second flaring mechanism 32 move by the same displacement in the same direction. Thus, the entire flaring mechanism can be adjusted simply by adjusting the first mounting base 33, which is convenient to operate and requires less adjustment time, thereby improving the overall working efficiency of the device.

[0102] The first mounting base 33 and the second mounting base 34 are connected by a column 35. The second mounting base 34 is fixed to the top of the column 35 and cannot move relative to the column 35. The first mounting base 33 can move up and down through the column 35 it is connected to, thereby changing the height of the first flaring mechanism 31 and the second flaring mechanism 32. The column 35 connection has low cost, simple structure, and can achieve height adjustment in a short time.

[0103] The adjustment mechanism 36 is located on the second mounting base 34 and connected to the first mounting base 33. The relative position of the first mounting base 33 and the second mounting base 34 can be adjusted by the adjustment mechanism 36. The adjustment mechanism 36 adjusts the height of the first flaring mechanism 31 and the second flaring mechanism 32 by raising or lowering the height of the first mounting base 33, which can accommodate soft-pack batteries 200 of different specifications and has a wider range of applications.

[0104] Specifically, a mounting base is a basic component specifically used to fix and support other parts, components, or the entire device. In some embodiments of this application, the flaring device 30 includes a first mounting base 33 and a second mounting base 34. The first mounting base 33 may be a flat plate structure. Both the first and second flaring devices 30 are connected to the first mounting base 33, and the first, second, and first mounting bases 33 form a whole. The second mounting base 34 is located above the first mounting base 33. The first and second mounting bases 33 can be connected by a column 35. The height of the second mounting base 34 remains fixed, while the first mounting base 33 can be displaced relative to the second mounting base by moving the column 35.

[0105] For example, the column 35 between the first mounting base 33 and the second mounting base 34 is telescopic. The column 35 can be divided into two parts with different diameters. One part of the column 35 is a hollow cylinder with a larger diameter, and the other part is a cylinder with a smaller diameter. The bottom of the hollow column 35 located on the first mounting base 33 is fixedly connected to the first mounting base 33, and the top is connected to the other part of the column 35. The column 35 with a smaller diameter can slide up and down inside the hollow column 35 with a larger diameter, thereby driving the flaring device 30 to move up and down.

[0106] In some embodiments of this application, the height of the first mounting base 33 can be adjusted by an adjustment mechanism 36 located on the surface of the second mounting base 34. The adjustment mechanism 36 is connected to the first mounting base 33. The force applied to the adjustment mechanism 36 drives the first mounting base 33 to move upward or downward relative to the second mounting base 34, thereby driving the first flaring mechanism 31 and the second flaring mechanism 32 to move upward or downward together. The adjustability of the height of the flaring mechanism further improves the adaptability of the flaring device 30 to soft-pack batteries 200 of different specifications and sizes, and enriches the applicable scenarios of the battery production line 100.

[0107] Please combine Figure 3 and Figure 4 In some embodiments of this application, the first flaring mechanism 31 includes an adapter frame 315. The adapter frame 315 is located above the first flaring mechanism 31 and is fixedly connected to the mounting plate 313. The first driving member 312 is connected to the adapter frame 315. The mounting plate 313 is provided with a slide rail 3131, and the adapter frame 315 can slide relative to the mounting plate 313 through the slide rail 3131. The adapter frame 315 is fixed to the first mounting base 33, so that the first flaring mechanism 31 can be installed on the first mounting base 33, and the suction member 311 can move left and right on the horizontal plane.

[0108] A connecting post 326 passes through the first mounting base 33. One end of the connecting post 326 is connected to the fixing member 324 of the second flaring mechanism 32, and the bottom end of the second driving member 322 is fixed to the first mounting base 33. In this way, the second flaring mechanism 32 can be installed on the first mounting base 33, and the second flaring mechanism 32 can move up and down by moving the fixing member 324 driven by the connecting post 326.

[0109] Please refer to again Figure 3 In some embodiments, the adjustment mechanism 36 includes a screw 361 and a handle 362. The screw 361 passes through the second mounting base 34 and is connected to the first mounting base 33, and the handle 362 is connected to one end of the screw 361.

[0110] In the above embodiment, the handle 362 is disposed on the upper surface of the second mounting base 34, and the screw 361 passes through the second mounting base 34 and is connected to the first mounting base 33. The rotation of the handle 362 can drive the rotation of the screw 361 of the adjustment mechanism 36. The screw 361 drives the first mounting base 33 to move up or down through the rotation of the first mounting base 33 in the threaded hole, thereby realizing the height adjustment of the first mounting base 33 and changing the overall height of the flaring device 30. The screw 361 and the handle 362 cooperate to make the adjustment mechanism 36 easier to implement and lower in cost.

[0111] Specifically, the handle 362 of the adjustment mechanism 36 is the position for external energy input to the adjustment mechanism 36 and the specific operating position for controlling the height of the first mounting base 33. The adjustment function of the adjustment mechanism 36 can be realized by manually shaking the handle 362.

[0112] In some embodiments of this application, the adjustment mechanism 36 can adjust the first mounting base 33 via a screw 361. The screw 361 passes through the second mounting base 34, and the handle 362 of the adjustment mechanism 36 is connected to the top of the screw 361. Thus, the handle 362 is located on the surface of the second mounting base 34. Since there are no other components on the surface of the second mounting base 34, the operation of the handle 362 is relatively convenient.

[0113] The screw 361 is connected to and fixed to the first mounting base 33. The screw 361 engages with a threaded hole on the second mounting base 34. When the handle 362 is rotated, the screw 361, located at one end of the surface of the second mounting base 34, extends out from the surface of the second mounting base 34, or moves downwards from a certain distance from the surface of the second mounting base 34 towards the surface of the second mounting base 34. This causes the column 35 located between the first and second mounting bases 33 to slide, thus adjusting the height of the first mounting base 33 and consequently the height of the flaring mechanism. In this way, the height adjustment of the flaring device 30 can be achieved through a simple and easy-to-operate structure, which is beneficial for overall cost control.

[0114] Please refer to Figure 7 , Figure 7 This is a partial perspective view of the support and positioning device 12 of this utility model. In some embodiments, the battery production line 100 further includes a support and positioning device 12 disposed on the conveyor belt 11. The support and positioning device 12 is provided with a positioning groove 121 for loading the soft-pack battery 200.

[0115] In the above embodiment, the support positioning devices 12 on the conveyor belt 11 are evenly arranged on the surface of the conveyor belt 11. Each support positioning device 12 can hold a soft-pack battery 200. The positioning groove 121 of the support positioning device 12 is the direct contact position of the soft-pack battery 200 on the support positioning device 12. Through the simple structure of the positioning groove 121, the soft-pack battery 200 can ensure its correct position on the support positioning device 12, and ensure the correct flaring position of the soft-pack battery 200 in the future.

[0116] Specifically, in some embodiments of this application, the support and positioning device 12 is used to constrain the pouch battery 200, enabling it to obtain and maintain an accurate and stable position and orientation in space, while safely bearing various loads. The support and positioning device 12 is provided with a positioning groove 121, which can be a precisely sized arc-shaped groove structure machined on the support and positioning device 12, used for supporting and positioning the pouch battery 200, thereby achieving the fixed installation of the pouch battery 200.

[0117] In addition, the support positioning device 12 can be slidably mounted on the fixed groove 111 of the conveyor belt 11. By adjusting its position on the fixed groove 111, the distance between a pair of support positioning devices 12 can be changed to fix and support soft-pack batteries of different lengths, thereby improving the compatibility of the support positioning device 12 with soft-pack batteries 200 of different specifications.

[0118] The support and positioning device 12 is located on the conveyor belt 11, at the middle position in the width direction of the conveyor belt 11. The soft-pack battery 200 is connected to the conveyor belt 11 through the support and positioning device 12, which ensures that the position of the soft-pack battery 200 on the conveyor belt 11 is fixed, and can be conveyed to the middle position of the flaring device 30 through the conveyor belt 11, ensuring that the edge of the air bag 201 of the soft-pack battery 200 is aligned with the tip of the flaring part 321, which is beneficial to improving the flaring quality of the flaring device 30.

[0119] Please refer to Figure 8 , Figure 8 This is a perspective view of the clamping device 13 of this utility model. In some embodiments, the battery production line further includes a clamping device 13 disposed on the conveying device 10. The clamping device 13 includes a gripper 131 and a fourth driving member 132 connected to the gripper 131. The fourth driving member 132 is used to drive the gripper 131 to open and close to clamp the soft-pack battery 200.

[0120] In the above embodiment, the fourth driving member 132 of the clamping device 13 is connected to the gripper 131. When the soft-pack battery 200 is about to be conveyed to the flaring device 30 via the conveying device 10, the gripper 131 contacts the bottom end of the soft-pack battery 200 under the driving action of the fourth driving member 132, and the soft-pack battery 200 is fixed by clamping the gripper 131. When the soft-pack battery 200 completes flaring and leaves the flaring device 30, the gripper 131 opens to release the fixation of the soft-pack battery 200. In this way, the clamping device 13 uses the gripper 131 to complete the clamping and fixing of the soft-pack battery 200, which has a simple structure and also facilitates the flaring device 30 to flare.

[0121] Specifically, the clamping device 13 can provide sufficient and stable clamping force to resist the inertial force or vibration generated during the flaring process, preventing the soft-pack battery 200 from moving or loosening, ensuring that the soft-pack battery 200 is in the correct position during flaring, and ensuring processing safety and quality. The clamping device 13 is mounted on the conveying device 10, and together with the positioning support device on the conveying device 10, it constrains the translational and rotational degrees of freedom of the soft-pack battery 200 in multiple directions, ensuring the stability of the position of the soft-pack battery 200 during the flaring process, and reducing the potential damage to the soft-pack battery 200 due to unstable positioning.

[0122] In some embodiments of this application, the clamping device 13 includes a gripper 131 and a fourth driving member 132 connected to the gripper 131. The gripper 131 is the core component of the clamping device 13. The core feature of the gripper 131 is that it has at least two relatively movable contact surfaces, that is, the gripper 131 has at least two surfaces that contact the surface of the soft-pack battery 200. The clamping function of the clamping device 13 depends on the opening and closing of the gripper 131 to achieve contact with the soft-pack battery 200, thereby restricting and fixing the soft-pack battery 200 through the force on the gripper 131.

[0123] For example, the grippers 131 are arranged opposite each other on both sides of the width direction of the conveyor belt 11, and the number of grippers 131 controlling one pouch battery 200 can be two. The grippers 131 can be a linkage mechanism, and the grippers 131 clamp the pouch battery 200 through the linkage mechanism. The connecting rods 1312 of the linkage mechanism are respectively connected to the grippers 131 located on both sides of the width of the conveyor belt 11, and the movement of the connecting rods drives the grippers 131 to complete the opening and closing action.

[0124] In some embodiments of this application, the gripper 131 is connected to the fourth drive member 132. Exemplarily, the fourth drive member 132 may be a cylinder-type drive member, which uses the energy of compressed air to drive the gripper 131 to perform linear reciprocating motion in the vertical direction.

[0125] Specifically, the clamping device 13 includes a fixed plate 133, and the linkage mechanism on the gripper 131 may include a pull rod 1311 and a connecting rod 1312. The pull rod 1311 is directly connected to the energy output end of the fourth driving member 132, and the connection method can be a rotating connection. A round rod 1313 is provided between the two connecting rods 1312, and the pull rod 1311 is rotatably connected to the round rod 1313. One end of the pull rod is connected to the energy output end of the fourth driving member 132, and its contact position with the fourth driving member 132 remains unchanged. The pull rod 1311 can rotate around the contact position between the two.

[0126] Both ends of the round rod 1313 are rotatably connected to the connecting rod 1312. When the fourth driving member 132 moves up and down, its linear motion is converted into the rotation of the pull rod 1311 around the connection point. When the pull rod 1311 rotates, the rotation of the pull rod 1311 can be converted into the combined horizontal and vertical motion of the round rod 1313. The connecting rod 1312 connected to it rotates around the connection point with the round rod 1313 under the action of the pull rod 1311. The fixed plate 133 is fixed, and the connecting rod 1312 is rotatably connected to the connecting plate 133. The connecting rod 1312 can rotate around the fixed plate 133 through the connection point, driving the gripper 131 to contact the soft-pack battery 200, thereby realizing the movement of the gripper 131 in the horizontal and vertical directions.

[0127] Thus, the clamping device 13 can achieve stable control of the movement of the gripper 131 through a simple linkage structure, and the output and input of the linkage structure are synchronized without relative lag, which is conducive to the clamping device 13 quickly completing the clamping action.

[0128] When the energy output end of the fourth drive member 132 moves upward, the gripper 131 moves away from the soft-pack battery 200; when the energy output end of the fourth drive member 132 moves downward, the gripper 131 moves closer to the soft-pack battery 200; in this way, the opening and closing function of the gripper 131 is realized, the clamping device 13 is controlled, and the stability of the flaring process of the soft-pack battery 200 is ensured.

[0129] In summary, in one embodiment, the flaring process of the battery production line 100 of this application for the soft-pack battery 200 is as follows:

[0130] The pouch battery 200 is fixed to the conveying device 10 by the support and positioning device 12. The pouch battery 200 is conveyed to the preheating device 20 by the conveyor belt 11. The corresponding air outlet 23 of the preheating device 20 is aligned with the pouch battery 200 to preheat it. After preheating, the pouch battery 200 is conveyed to the flaring device 30 by the conveyor belt 11. The clamping device 13 located below the flaring device 30 clamps and fixes the pouch battery 200 with the grippers 131. The first flaring mechanism 31 pulls open the air bag 201 of the pouch battery 200 to form a bag opening through the suction member 311. Then, the flaring member 321 of the second flaring mechanism 32 fully expands the air bag 201, completing the flaring of the pouch battery 200.

[0131] The battery production line 100 of this application has a high degree of integration, good flaring quality, strong adjustability, wide range of applicable scenarios, and can meet the requirements of fast battery production cycle.
