Description

Technical Field

[0001] This invention relates to the field of copper foil cutting equipment technology, and more specifically to a cutting equipment for processing composite copper foil. Background Technology

[0002] Composite copper foil is a new type of battery current collector material. It adopts a sandwich structure of "polymer substrate (such as PET / PP) + two nano copper layers on both sides". The thickness is only 4-10 micrometers. Compared with traditional pure copper foil, it reduces the weight by more than 50%. It can improve the energy density of the battery and suppress lithium dendrite puncture. It has the potential for high safety and low cost, and is an important development direction for the next generation of lithium battery anode current collectors.

[0003] Currently, composite copper foil requires cutting according to requirements during processing. However, the composite copper foil is relatively thin, and it needs to be laid manually on the platform surface during fixing. This manual laying process can cause wrinkles in the composite copper foil, resulting in insufficient dimensional accuracy after cutting and affecting its subsequent use. Furthermore, during the laying and fixing process, the surface of the composite copper foil is sensitive and easily scratched or contaminated. Dust particles on the platform surface can also cause varying degrees of damage to the surface of the composite copper foil, leading to problems with the quality of the cut composite copper foil. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, embodiments of the present invention provide a cutting device for processing composite copper foil to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cutting device for processing composite copper foil, comprising a worktable, support frames fixedly connected to both sides of the worktable surface, a fixed plate fixedly connected to the top of the support frames, a laser cutting blade provided at the bottom of the fixed plate at the top of the worktable, a movable plate movably connected to the inside of the top of the worktable, a clamping assembly fixedly connected to the side of the movable plate near the support frames, a fixed assembly fixedly connected to the side of the top of the worktable near the clamping assembly, and a limit component fixedly connected to the top of the worktable near the fixed assembly and away from the clamping assembly. A dust removal component is fixedly connected to the top of the workbench near the limiting component and away from the fixing component. A mounting plate is fixedly connected to the top of the workbench near the dust removal component and away from the limiting component. A protective shell is fixedly connected to one side of the workbench surface. A moving motor is fixedly connected to the top of the protective shell. By providing a clamping component, a fixing component, and a moving plate, it is beneficial to clamp one side of the composite copper foil during the fixing process. With the movement of the moving plate, the composite copper foil is moved and laid on the surface of the moving plate. Thus, the composite copper foil is quickly fixed with the fixing component, reducing manual operation steps and labor intensity.

[0006] In a preferred embodiment, a rectangular groove is provided on the top of the workbench at the position of the movable connecting plate, and a composite copper foil winding shaft is movably sleeved on the inner position of the adjacent side of the mounting plate.

[0007] In a preferred embodiment, a transmission rack is fixedly connected to the surface of the movable plate near the protective shell. A circular hole is formed on the top of the movable plate near the clamping component, and a regularly arranged adsorption hole is formed on the top of the movable plate near the circular hole away from the clamping component. By providing a limiting component and a movable plate, it is beneficial to pull the composite copper foil more evenly, so that the composite copper foil is more even when fixed, thereby increasing the accuracy of subsequent cutting of the composite copper foil and avoiding affecting the subsequent use of the composite copper foil.

[0008] In a preferred embodiment, the clamping assembly includes a rectangular plate, a clamping motor is fixedly connected to the bottom of the rectangular plate, limit shafts are fixedly connected to both sides of the top of the rectangular plate, a threaded telescopic rod is movably sleeved inside the rectangular plate, a clamping block is sleeved on the surface of the limit shaft and the threaded telescopic rod, and a pressing rod is provided at the bottom of the clamping block.

[0009] In a preferred embodiment, a pressing plate is movably sleeved inside the movable plate and located within the circular hole. A connecting rod is fixedly connected to the bottom of the pressing plate. The connecting rod is U-shaped, and a rubber plug is fixedly connected to the other end of the connecting rod. The rubber plug is located at the bottom of the adsorption hole in the movable plate. A spring is fixedly connected to the bottom of the pressing plate and at the middle position adjacent to the connecting rod. The spring facilitates the pressing plate to be pushed back when the clamping assembly is raised, thereby blowing air upwards onto the adsorbed composite copper foil, which in turn facilitates the separation of the cut composite copper foil from the movable plate.

[0010] In a preferred embodiment, a transmission gear is movably sleeved inside the protective shell, and the transmission gear is connected to a moving motor.

[0011] In a preferred embodiment, the fixing component includes a fixing frame, a movable fixing block is movably connected to the inner position of an adjacent side of the fixing frame, a movable threaded valve is movably connected to the top position of the fixing frame, and the bottom position of the movable threaded valve is located at the top of the movable fixing block.

[0012] In a preferred embodiment, the limiting component includes a first fixed circular plate, with a limiting rod shaft movably connected to an adjacent side of the first fixed circular plate; the dust removal component includes a second fixed circular plate, with a dust removal pipe fixedly sleeved inside an adjacent side of the second fixed circular plate; a dust removal motor is fixedly connected to the surface of the second fixed circular plate on one side of the top of the workbench; and a dust collection box is fixedly connected to the surface of the second fixed circular plate on the other side of the top of the workbench.

[0013] In a preferred embodiment, the dust removal pipe has regularly arranged dust suction holes on the surface near the moving plate, the dust collection box has a dust collection cavity inside, and the dust collection box has a barrier mesh on the surface away from the second fixed circular plate. By providing a dust removal component, it is beneficial to clean the dust particles on the surface of the moving plate during the laying and fixing of the composite copper foil, so as to avoid damage to the surface of the composite copper foil caused by the dust, thereby improving the quality of the cut composite copper foil.

[0014] The technical effects and advantages of this invention are as follows:

[0015] The present invention, by providing a clamping component, a fixing component, and a moving plate, facilitates the fixing of composite copper foil. The clamping component clamps one side, and the moving plate moves to lay the composite copper foil on the surface of the moving plate. Thus, the fixing component fixes the composite copper foil quickly, reducing manual operation steps and reducing labor intensity.

[0016] The present invention, by providing a limiting component and a moving plate, facilitates the smooth pulling of the composite copper foil, thereby making the composite copper foil more flat when fixed, which in turn increases the accuracy of subsequent cutting of the composite copper foil and avoids affecting the subsequent use of the composite copper foil.

[0017] The present invention incorporates a dust removal component, which facilitates the cleaning of dust particles on the surface of the moving plate during the laying and fixing of the composite copper foil. This prevents dust from damaging the surface of the composite copper foil and improves the quality of the cut composite copper foil. Attached Figure Description

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The cutting device for processing composite copper foil involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Reference Figures 1-7As shown, the present invention provides a cutting device for processing composite copper foil, including a worktable 1, a support frame 2 fixedly connected to both sides of the surface of the worktable 1, a fixed plate 3 fixedly connected to the top of the support frame 2, a laser cutting blade 4 opened at the bottom of the fixed plate 3 at the top of the worktable 1, a movable plate 5 movably connected to the inside of the top of the worktable 1, a clamping component 6 fixedly connected to the side of the movable plate 5 near the support frame 2, a fixed component 7 fixedly connected to the side of the top of the worktable 1 near the clamping component 6, a limiting component 8 fixedly connected to the top of the worktable 1 near the fixed component 7 and away from the clamping component 6, a dust removal component 9 fixedly connected to the top of the worktable 1 near the limiting component 8 and away from the fixed component 7, a mounting plate 10 fixedly connected to the side of the top of the worktable 1 near the dust removal component 9 and away from the limiting component 8, a protective shell 11 fixedly connected to one side of the surface of the worktable 1, and a moving motor 12 fixedly connected to the top of the protective shell 11.

[0028] In this embodiment, by providing a clamping component 6, a fixing component 7, and a moving plate 5, it is beneficial to clamp one side of the composite copper foil during the fixing process. With the movement of the moving plate 5, the composite copper foil is moved and laid on the surface of the moving plate 5. Thus, the composite copper foil is quickly fixed by the fixing component 7, reducing manual operation steps and reducing labor intensity.

[0029] The workbench 1 has a rectangular groove 101 at the top of the movable connecting plate 5, and a composite copper foil winding shaft 1001 is movably sleeved on the inner side of the adjacent side of the mounting plate 10.

[0030] The movable plate 5 is fixedly connected to a transmission rack 501 on the surface near the protective shell 11. A circular hole 502 is opened on the top of the movable plate 5 and on the side near the clamping component 6. A regularly arranged adsorption hole 503 is opened on the top of the movable plate 5 near the circular hole 502 and away from the clamping component 6. With the limiting component 8 and the movable plate 5, it is beneficial to pull the composite copper foil more evenly, so that the composite copper foil is more even when fixed, thereby increasing the accuracy of subsequent cutting of the composite copper foil and avoiding affecting the subsequent use of the composite copper foil.

[0031] The clamping assembly 6 includes a rectangular plate 601, a clamping motor 602 fixedly connected to the bottom of the rectangular plate 601, limit shafts 603 fixedly connected to both sides of the top of the rectangular plate 601, a threaded telescopic rod 604 movably sleeved inside the rectangular plate 601, and a clamping block 605 sleeved on the surface of the limit shaft 603 and the threaded telescopic rod 604, with a pressing rod 606 at the bottom of the clamping block 605.

[0032] A pressing plate 13 is movably sleeved inside the movable plate 5 and located inside the circular hole 502. A connecting rod 1301 is fixedly connected to the bottom of the pressing plate 13. The connecting rod 1301 is U-shaped, and a rubber plug 1302 is fixedly connected to the other end of the connecting rod 1301. The rubber plug 1302 is located at the bottom of the adsorption hole 503 in the movable plate 5. A spring is fixedly connected to the bottom of the pressing plate 13 and at the middle position adjacent to the connecting rod 1301. The spring helps to push the pressing plate 13 back to its original position when the clamping component 6 is raised, thereby blowing the adsorbed composite copper foil upwards, which facilitates the separation of the cut composite copper foil from the movable plate 5.

[0033] The protective shell 11 has a transmission gear 14 movably sleeved inside, and the transmission gear 14 is connected to the moving motor 12.

[0034] The fixing component 7 includes a fixing frame 701, a movable fixing block 702 is movably connected to the inner position of the adjacent side of the fixing frame 701, a movable threaded valve 703 is movably connected to the top position of the fixing frame 701, and the bottom position of the movable threaded valve 703 is located at the top of the movable fixing block 702.

[0035] The limiting component 8 includes a first fixed circular plate 801, with a limiting rod shaft 802 movably connected to the adjacent side of the first fixed circular plate 801. The dust removal component 9 includes a second fixed circular plate 901, with a dust removal pipe 902 fixedly sleeved inside the adjacent side of the second fixed circular plate 901. A dust removal motor 903 is fixedly connected to the surface of the second fixed circular plate 901 on one side of the top of the workbench 1, and a dust collection box 904 is fixedly connected to the surface of the second fixed circular plate 901 on the other side of the top of the workbench 1.

[0036] The dust removal pipe 902 has neatly arranged dust suction holes 9021 on the surface near the moving plate 5, and the dust collection box 904 has a dust collection cavity 9041 inside. The dust collection box 904 has a barrier net 9042 on the surface away from the second fixed circular plate 901. By providing the dust removal component 9, it is beneficial to clean the dust particles on the surface of the moving plate 5 when the composite copper foil is laid and fixed, so as to avoid the dust on its surface from causing damage to the surface of the composite copper foil, thereby improving the quality of the cut composite copper foil.

[0037] The working principle of this invention is as follows: First, when preparing to cut the composite copper foil, one end of the composite copper foil wound on the surface of the composite copper foil winding shaft 1001 is pulled so that the composite copper foil is located at the top of the dust removal pipe 902 and passes through the bottom of the limiting rod shaft 802. Then, the composite copper foil reaches the bottom of the fixing component 7 via the limiting rod shaft 802. Next, the composite copper foil is pulled to the bottom of the clamping block 605. Then, the clamping motor 602 is started, causing the clamping motor 602 to drive the threaded telescopic rod 604 to rotate. Then, the rotation of the threaded telescopic rod 604 passes through the limiting rods 602 on both sides of the top of the rectangular plate 601. The clamping block 605, which is restricted by 03, moves the extrusion rod 606 closer to the circular hole 502 at the top of the moving plate 5. The clamping block 605 then clamps the composite copper foil. While the composite copper foil is being clamped, the extrusion rod 606 extrudes the extrusion plate 13. The extrusion plate 13 then moves the rubber plug 1302. The rubber plug 1302 moves and draws in air from the adsorption hole 503. The composite copper foil at the top of the adsorption hole 503 is then adsorbed and adhered to the surface of the moving plate 5, thus fixing one end of the composite copper foil.

[0038] Then, the moving motor 12 is started, causing it to drive the transmission gear 14 inside the protective shell 11. The transmission gear 14 then drives the transmission rack 501 on one side of the moving plate 5, which is movably connected inside the rectangular groove 101. At this time, the transmission rack 501 drives the moving plate 5 to slide to one side inside the rectangular groove 101. Then, the composite copper foil, which is fixed by the clamping component 6, is moved and evenly laid on the surface of the moving plate 5 under the restriction of the limiting component 8. At this time, the composite copper foil on the surface of the composite copper foil winding shaft 1001, which is movably connected in the middle of the mounting plate 10, is pulled. During the process of the moving plate 5 moving and laying the composite copper foil, the dust removal motor 903 is started, driving the air inside the dust removal pipe 902 to blow towards the dust collection box 904. The air inside the dust removal pipe 902 is driven to cause the dust particles on the surface of the moving plate 5 to be adsorbed into the dust removal pipe 902 at the dust suction hole 9021 and then enter the dust collection box. Inside the dust collection chamber 9041, dust is blocked by the barrier net 9042, allowing air to escape through the barrier net 9042 and then collect the dust through the dust collection chamber 9041. At this time, the surface of the moving plate 5 without composite copper foil is cleaned, making the composite copper foil lay more evenly. After the moving plate 5 extends to the appropriate position, the moving motor 12 is turned off, and the moving threaded valve 703 is rotated, causing the moving threaded valve 703 to drive the moving fixing block 702 inside the fixing frame 701 to move downward. The moving fixing block 702 then fixes one side of the composite film surface. The laser cutting blade 4 at the bottom of the fixing plate 3 is then adjusted to the appropriate cutting position and the laser cutting blade 4 is started. The laser cutting blade 4 then cuts the composite copper foil fixed on the surface of the moving plate 5. After cutting, the cut composite copper foil is removed, and the composite copper foil is processed and cut again according to the above operation.

[0039] In conclusion, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
