Description

Technical Field

[0001] This invention belongs to the field of battery production technology, and in particular relates to a battery component packaging machine for a battery assembly production line. Background Technology

[0002] Lithium-ion batteries are a type of battery that uses lithium metal or lithium alloys as the positive / negative electrode materials and a non-aqueous electrolyte solution. Due to the highly reactive chemical properties of lithium metal, its processing, storage, and use require very strict environmental control. With the development of science and technology, lithium-ion batteries have become the mainstream technology.

[0003] In existing technologies, after stacking multiple finished batteries using a battery stacker, a protective film is typically wrapped around the perimeter of the battery stack to protect it. Currently, this is usually done manually using hand-held film rollers. This method not only increases the labor intensity for workers but also carries the risk of the battery stack tipping over due to excessive force during the wrapping process. Therefore, there is an urgent need to research a battery component packaging machine for a battery assembly production line to solve the above problems. Summary of the Invention

[0004] The present invention provides a battery component packaging machine for a battery assembly production line, the purpose of which is to solve the technical problems mentioned in the background art above.

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Specific Implementation Example 1:

[0030] Please see Figure 1-3 As shown, the present invention is a battery packing machine for a battery assembly production line, comprising four vertically arranged support columns 1 arranged side by side; the upper ends of two adjacent support columns 1 are connected by a bearing column 2; a horizontally arranged support strip 3 is vertically fixed in the middle of the bearing column 2; the support strip 3 is arranged between the four support columns 1; a side support assembly 4 for supporting the side of the finished battery stack is installed on the support strip 3; a rotary drive assembly 5 is installed between the four support strips 3; a film-laying assembly 6 and a film-cutting assembly 7 are installed on the rotary drive assembly 5.

[0031] In use, the finished battery stack is placed between four support columns 1. The rotary drive component 5 drives the film-laying component 6 to wrap the protective film around the perimeter of the finished battery stack. At the same time, the side support component 4 supports the sides of the finished battery stack. After the protective film is wrapped, the film-cutting component 7 cuts the protective film on the film-laying component 6. This not only effectively improves the packaging efficiency of the battery stack, but also effectively avoids problems such as the finished battery stack tipping over during the wrapping process of the protective film. It also greatly reduces the labor intensity of workers. Specific Implementation Example 2:

[0033] Based on specific embodiment one, as follows Figure 4-5As shown, the side support assembly 4 includes a linear drive component mounted on the support strip 3 and a drive strip 401 vertically connected to the lower part of the linear drive component; the linear drive component is used to drive the drive strip 401 to move along the length direction of the support strip 3; a plurality of side support strips 402 are horizontally fixed from top to bottom on one side of the drive strip 401; the linear drive component includes a guide frame 403 slidably sleeved on the support strip 3; a positioning rack 404 parallel to the support strip 3 is inserted inside the guide frame 403; the positioning rack 404 is fixed on the upper surface of the support strip 3; a transmission gear 405 meshes on the positioning rack 404; the transmission gear 405 is disposed inside the guide frame 403; a first servo motor 406 is horizontally fixed on one side edge of the guide frame 403; the output shaft of the first servo motor 406 passes through one side edge of the guide frame 403 and is coaxially fixed with the transmission gear 405; the output shaft of the first servo motor 406 is clearance-fitted with one side edge of the guide frame 403.

[0034] In use, when the rotary drive assembly 5 drives the film-laying assembly 6 to move to any side of the finished battery stack, the side support assembly 4 on that side does not support the finished battery stack (i.e., the side support bar 402 on that side is located at the end of the support bar 3 away from the rotary drive assembly 5), while the side support assemblies 4 on the other three sides of the finished battery stack do support the finished battery stack (i.e., the side support bars 402 on the other three sides are located at the end of the support bar 3 close to the rotary drive assembly 5, and one surface of the side support bar 402 is in contact with one surface of the protective film already wrapped on the finished battery stack). In other words, when the rotary drive assembly 5 drives the film-laying assembly 6 to move to any side of the finished battery stack, only the side support assembly 4 corresponding to that side does not support the finished battery stack, while the side support assemblies 4 on the other three sides of the finished battery stack do support the finished battery stack, thereby avoiding problems such as the finished battery stack tipping over during the wrapping of the protective film. Specific Implementation Example 3:

[0036] Based on the second specific embodiment, as follows Figure 6-7 As shown, the rotary drive assembly 5 includes a mounting plate 501 horizontally fixed between four support strips 3; a second servo motor 502 is vertically fixed on the upper surface of the mounting plate 501; the output shaft of the second servo motor 502 passes through the mounting plate 501 and is radially fixed to a horizontally arranged rotating strip 503; the output shaft of the second servo motor 502 is clearance-fitted with the mounting plate 501; the film-laying assembly 6 and the film-cutting assembly 7 are both mounted on the end of the rotating strip 503 away from the second servo motor 502. In use, the second servo motor 502 drives the stationary rotating strip 503 to rotate, thereby realizing the circumferential movement of the film-laying assembly 6 and the film-cutting assembly 7 around the finished battery stack, thus achieving the winding of the protective film.

[0037] Among them, such as Figure 6-8As shown, the film-laying assembly 6 includes a lifting drive unit vertically mounted on a rotating slat 503; a movable seat 601 with a "[" shaped structure is vertically mounted on the lifting drive unit; a vertically arranged film roller 602 is rotatably mounted on the inner side of the movable seat 601; the film roller 602 is disposed between the movable seat 601 and the second servo motor 502; the lifting drive unit includes a third servo motor 603 vertically fixed to the upper surface of the rotating slat 503 and a slide rail 604 vertically fixed to the lower surface of the rotating slat 503; the output shaft of the third servo motor 603 passes through the rotating slat 503 and is coaxially fixed to a transmission screw 605; the transmission screw 605 is arranged parallel to one side of the slide rail 604; the output shaft of the third servo motor 603 is clearance-fitted with the rotating slat 503; a lifting nut 606 is sleeved on the transmission screw 605; one side of the lifting nut 606 is in contact with one surface of the slide rail 604; one surface of the lifting nut 606 is fixed to the middle of the movable seat 601. In use, when the film-dispensing assembly 6 is driven by the rotary drive assembly 5 to make a circular motion, the third servo motor 603 drives the transmission screw 605 to rotate back and forth, causing the lifting screw nut 606 to move up and down on the transmission screw 605, thereby releasing the protective film on the film roller 602 onto the periphery of the finished battery stack.

[0038] Among them, such as Figure 6-7 and Figure 9 As shown, the film cutting assembly 7 is located on the side of the film feeding assembly 6 away from the second servo motor 502. The film cutting assembly 7 includes a fourth servo motor 701 vertically fixed to the upper surface of the rotating strip 503. The output shaft of the fourth servo motor 701 passes through the rotating strip 503 and is radially fixed to a horizontally arranged swing arm 702. The output shaft of the fourth servo motor 701 is clearance-fitted with the rotating strip 503. A vertically arranged carrier roller 703 is rotatably mounted on the end of the swing arm 702 away from the fourth servo motor 701. Multiple vertically arranged cutters 704 are evenly distributed on the circumferential sidewall of the carrier roller 703. After the protective film is wrapped, the fourth servo motor 701 drives the swing arm 702 to rotate, causing the carrier roller 703 to swing between the film roller 602 and the second servo motor 502, thereby enabling the cutters 704 to cut the protective film on the film roller 602, further ensuring the packaging efficiency of the finished battery stack.
