Description

Technical Field

[0001] This utility model relates to the field of new energy battery production equipment technology, specifically to a battery cover assembly production line. Background Technology

[0002] In the field of new energy battery manufacturing, the battery cover, as a key component, directly affects the overall performance and production capacity of the battery due to its assembly quality and production efficiency. With the rapid development of the new energy industry, the market demand for batteries continues to rise. Battery manufacturers are placing higher demands on the space utilization, compactness, and automation of their production lines. Especially in production scenarios with limited factory space, how to reduce the space occupation of production line equipment while ensuring production efficiency has become an important problem that urgently needs to be solved in the industry.

[0003] Currently, most mainstream battery cover assembly lines adopt a linear layout structure, where various work modules (such as feeding, welding, testing, and unloading modules) are arranged sequentially along a straight line, and workpieces are transferred between modules via conveyor belts or transfer mechanisms. However, this linear layout has significant space drawbacks: on the one hand, the linearly arranged work modules require a long longitudinal or transverse space, resulting in a large overall floor area for the production line. This is especially true when multiple lines are produced in parallel, significantly increasing the demand for factory space and raising production site costs for enterprises. On the other hand, the large spacing between work modules in a linear layout results in a long workpiece transfer path, which not only increases transfer time and reduces production cycle time but also requires longer conveyor mechanisms or more transfer equipment, further exacerbating the space occupation problem. The excessively large equipment space and long workpiece transfer distances place higher demands on the installation accuracy of work modules at each station, requiring more time for equipment adjustment and affecting overall production capacity. Utility Model Content

[0004] To address the aforementioned issues, this utility model provides a battery cover assembly production line. The circular assembly line saves space occupied by production equipment. By installing robotic arms one and two in the middle of the rotary table, the overall diameter of the frame is further reduced, while making the layout of each working module on the frame more compact.

[0005] To achieve the above objectives, this utility model embodiment adopts the following technical solution: a battery cover assembly production line, including a frame, a rotary table above the frame, floating tooling on the rotary table, and a series of modules arranged around the rotary table, including a terminal feeding module, a busbar feeding module, an insulating cover feeding module, a sealing ring feeding module, an aluminum cover feeding module, an insulating sheet feeding module, a terminal feeding module, and an output module. A welding module is provided between the busbar feeding module and the insulating cover feeding module, and a stamping module is provided between the terminal feeding module and the output module. A drive unit is provided below the rotary table, and a mounting plate located above the rotary table is provided in the middle of the drive unit. Robotic arm one and robotic arm two are provided on the mounting plate, corresponding to the positions of the insulating cover feeding module and the aluminum cover feeding module, respectively.

[0006] As a further improvement to the above technical solution:

[0007] The drive unit includes a rotary gear disk, a motor is provided on one side of the rotary gear disk, and a support column for fixing the mounting plate is provided in the middle of the rotary gear disk.

[0008] The floating fixture includes a base, a workpiece support plate is provided above the base, a return spring is provided between the workpiece support plate and the base, a top head is provided in the middle of the workpiece support plate, and a guide rod is provided at the lower part of the top head.

[0009] The base is provided with a through hole, and a limiting boss is provided in the through hole. The workpiece support plate is provided with a guide block that is connected to the through hole. A guide hole is provided in the middle of the guide block. A storage cavity for placing the top head is provided in the upper part of the guide hole. An axial retaining ring is provided on the guide rod located below the limiting boss.

[0010] The distance between the top head and the upper end face of the workpiece support plate is less than the distance between the workpiece support plate and the base.

[0011] Both the welding module and the stamping module are equipped with bases at their lower parts, and each base has a load-bearing block at its front end corresponding to the position of the guide rod.

[0012] The rotary table is provided with a clearance hole for the guide rod to pass through, and a bushing is provided in the clearance hole.

[0013] Each of the pole feeding module, sealing ring feeding module, insulating sheet feeding module, and terminal feeding module is equipped with a feeder. Each feeder has a positioning seat at its lower part, and an adjustment plate is located below the positioning seat. The adjustment plate and the positioning seat are connected by a clamping bolt. A top block is provided on the side wall of the adjustment plate, and limit plates are provided on both sides of the top block. Each limit plate is equipped with a clamping bolt that abuts against the top block.

[0014] The busbar loading module, insulating cover loading module, and aluminum cover loading module are all equipped with a storage tray. The storage tray has multiple storage areas, and each storage area has a lifting channel in the middle. A fixing plate is installed below the storage tray, and a reducer is installed on the fixing plate. A linear electric cylinder is installed below the fixing plate, and the extension end of the linear electric cylinder is equipped with a lifting support plate corresponding to the position of the lifting channel.

[0015] The feed module of the manifold is equipped with a material transfer plate, the material transfer plate is equipped with a negative pressure suction cup, and a detection probe is installed in the middle of the material transfer plate.

The mounting plate is equipped with robotic arm one and robotic arm two, which correspond to the positions of the insulating cover loading module and the aluminum cover loading module, respectively. Installing robotic arm one and robotic arm two in the center of the rotary table can save installation space on the frame, making the installation positions of each operating module more compact, reducing the overall diameter of the frame, and also reducing the swing range of the robotic arm during material handling by installing the robotic arm and the storage tray on both sides of the floating fixture when picking up insulating cover and aluminum cover. This saves the space that the robotic arm needs to reserve during swing, making the layout of the entire production line more compact.

[0017] Through the improvements to each workstation and the design of the installation location, the diameter of the frame provided by this utility model is controlled between 1.8 and 2.2 meters. This allows the equipment to be transported using a conventional truck (2.4 meters wide). The advantage of transporting the equipment as a whole is that it can be adjusted directly during production, without the need for personnel to follow the shipment for assembly, adjustment, or other operations. Production can begin immediately after installation. Attached Figure Description

[0031] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0032] like Figure 1-12 As shown, the battery cover assembly production line of this embodiment is based on the frame 1. A core transmission component, a turntable 2, is set above the frame 1. Floating fixtures 3 for carrying workpieces are evenly arranged on the turntable 2 to realize the transfer of workpieces between processes.

[0033] Around the rotary table 2, following the assembly process of the battery cover, there are sequentially arranged terminal post feeding module 4, busbar feeding module 5, insulating cover feeding module 6, sealing ring feeding module 7, aluminum cover feeding module 8, insulating sheet feeding module 9, terminal feeding module 10, and discharge module 11, completing the entire process from feeding each component to discharging the finished product.

[0034] Among them, a welding module 12 for welding the busbar and the terminal is provided between the busbar loading module 5 and the insulating cover plate loading module 6; and a stamping module 13 for stamping and fixing the terminals is provided between the terminal loading module 10 and the discharge module 11.

[0035] To drive the rotary table 2 to operate, a drive unit 14 is provided below the rotary table 2. The drive unit 14 includes a rotary gear 18. A motor 19 that provides power is provided on one side of the rotary gear 18. At the same time, a support column 20 is provided in the middle of the rotary gear 18. A mounting plate 15 located above the rotary table 2 is fixed to the top of the support column 20. On the mounting plate 15, corresponding to the positions of the insulating cover loading module 6 and the aluminum cover loading module 8, are respectively equipped with robotic arms 16 and 17 for material gripping and transfer, assisting in the loading of insulating and aluminum covers. Mounting robotic arms 16 and 17 in the middle of the rotary table 2 saves installation space on the frame 1, making the installation positions of each working module more compact and reducing the overall diameter of the frame 1. Furthermore, when picking up insulating and aluminum covers, the robotic arms and storage trays are positioned on opposite sides of the floating fixture 3, reducing the swing range of the robotic arms during material gripping. This saves space that would otherwise be needed for the robotic arms during swing, making the entire production line layout more compact and further reducing the operating area occupied by the entire production line.

[0036] The floating fixture 3 has a base 21. A workpiece support plate 22 is movably mounted on the top of the base 21. A return spring 23 connects the workpiece support plate 22 to the base 21, enabling the workpiece support plate 22 to elastically return to its original position. A top head 24 is mounted in the middle of the workpiece support plate 22. A guide rod 25 extending to the bottom of the rotary table 2 is connected to the lower part of the top head 24. A through hole 26 is provided on the base 21, and a limiting boss 27 is provided inside the through hole 26. A guide block 28 extending into the through hole 26 is provided on the workpiece support plate 22. A guide hole 29 is provided in the middle of the guide block 28, and a storage cavity 30 for placing the top head 24 is formed at the top of the guide hole 29. An axial retaining ring 31 located below the limiting boss 27 is installed on the guide rod 25 to limit the upward movement distance of the guide rod 25. The distance between the top head 24 and the upper end face of the workpiece support plate 22 is... The distance between the workpiece support plate 22 and the base 21 is less than that between the workpiece support plate 22 and the base 21. When the workpiece support plate 22 sinks below the top head 24 during stamping or welding, the top head 24 begins to bear force. At this time, there is still a gap between the workpiece support plate 22 and the base, which is 0.5mm. This gap is used to prevent the base 21 from being damaged or excessively worn after being subjected to the impact force of the operation. The lower part of the welding module 12 and the stamping module 13 are both equipped with a base 32. The front end of each base 32 is equipped with a load-bearing block 33 corresponding to the position of the guide rod 25. During welding or stamping operations, the pressure on the top head 24 is transmitted to the load-bearing block 33 through the guide rod 25. This prevents the edge of the rotary table 2 from deflecting or deforming due to pressure impact during welding and stamping, which can effectively improve the operational stability and service life of the product and reduce the maintenance frequency.

[0037] The welding module 12 uses an ultrasonic welding machine to complete the welding operation. After the welding is completed, the welding surface is the lower surface of the pole, which will not affect the connection strength between the pole and the busbar. At the same time, it ensures the smoothness of the working surface of the busbar and will not affect the assembly of other components.

[0038] The stamping head in the stamping module 13 is a double-stroke stamping head. First, the first stroke presses down the workpiece support plate 22. Then, after pressing down, the stamping head presses the terminal and the pole together. At this time, the stamping pressure is received by the top head 24 and then transmitted to the load-bearing block 33 by the guide rod 25.

[0039] Each of the pole feeding module 4, sealing ring feeding module 7, insulating sheet feeding module 9, and terminal feeding module 10 is equipped with a feeder 37 for material conveying. Each feeder 37 has a positioning seat 38 at its lower part, and an adjustment plate 39 is installed below the positioning seat 38. The adjustment plate 39 and the positioning seat 38 are fixedly connected by clamping bolts 40. A top block 41 is provided on the side wall of the adjustment plate 39, and a limit plate 42 is provided on both sides of the top block 41. Each limit plate 42 is screwed with a tightening bolt 43 that abuts against the top block 41. The position of the adjustment plate 39 can be finely adjusted by adjusting the tightening bolts 43 to ensure feeding accuracy. Compared with traditional track-type adjustment equipment, the adjustment plate 39 occupies less area, and the feeder can be synchronously adjusted on the X and Y axes with one adjustment, without the need for two adjustments. While reducing the space occupied, it can also greatly improve the efficiency of equipment fine adjustment.

[0040] The busbar loading module 5, the insulating cover loading module 6, and the aluminum cover loading module 8 are all equipped with a storage tray 44 for storing materials. The storage tray 44 is divided into multiple independent storage areas 45, and a lifting channel 46 is opened in the middle of each storage area 45. A fixing plate 47 is provided below the storage tray 44, and a reducer 48 is installed on the fixing plate 47. A linear electric cylinder 49 is equipped below the fixing plate 47. The telescopic end of the linear electric cylinder 49 is connected to a lifting support plate 50 corresponding to the position of the lifting channel 46. The lifting support plate 50 is driven to rise and fall by the linear electric cylinder 49, lifting the material in the storage area 45 upwards for easy retrieval. Multiple guide rods are installed around each storage area 45 to guide the rising of the material. Since the material is in the form of thin sheets, multiple sheets can be stacked together in each storage area 45. After the material in a storage area 45 is used up, the linear electric cylinder 49 resets, and the reducer drives the storage tray 44 to rotate, changing to the next storage area 45. At this time, the material in the previous discharge area can be refilled. This design can increase the storage capacity of the material, save the space occupied by each working position, and achieve non-stop feeding, ensuring the continuity of production line production.

[0041] The material transfer plate module 5 is also equipped with a material transfer plate 51. The material transfer plate 51 is equipped with four negative pressure suction cups 52, which are located at the four corners of the material transfer plate 51. A detection probe 53 is located in the middle of the material transfer plate 51. During operation, the material suction cup first picks up the manifold from the storage tray 44 and then places it on the material transfer plate 51. If the material sticks together (i.e., the two manifolds are adsorbed together), the negative pressure suction cup on the material transfer plate 51 will adsorb the material on the lower layer to avoid overlapping during feeding. The detection probe 53 is used to detect whether there is material stored on the material transfer plate 51. If there is material stored, a signal is sent to the central control console, and the material suction cup can remove the stored material during the next feeding.

[0042] It should be noted that the surface of the manifold has multiple grooves, and the material suction cup is made of flexible silicone material. When picking up materials, it can deform and adhere to the surface of the material to complete the gripping operation. Moreover, the suction force of the material suction cup is greater than that of the negative pressure suction cup, ensuring that the material can be adsorbed and picked up.

[0043] Through the improvements to each workstation and the design of the installation position, the diameter of the frame 1 provided by this utility model is controlled between 1.8 and 2.2 meters. This allows the equipment to be transported using a conventional truck (2.4 meters wide). The advantage of transporting the equipment as a whole is that it can be directly adjusted during production, without the need for personnel to follow the shipment for assembly and adjustment. Production can begin immediately after installation. To facilitate the relocation of the production line and its integration with the production workshop, the bottom of the frame 1 uses a combination of leveling bolts and wheels to facilitate the transfer and repositioning of the equipment.
