[0002] Lithium batteries are highly efficient and high-capacity energy storage devices. Compared with the lead-acid batteries that people used to use in large quantities, they represent a significant improvement, achieving advantages such as small size, light weight, high power, and long life. Each lithium battery consists of many polarized foils connected in series. These foils are made by coating carbon powder or other electrode materials onto the surface of non-ferrous metals.

[0003] When installing tabs on lithium battery electrode foils, the lithium battery electrode foils need to be fixed. However, fixing the lithium battery electrode foils can easily obstruct the surface of the lithium battery electrode foils, causing obstruction and hindering the installation of the tabs.

The threaded rod passes through the sliding base and is threadedly connected to the sliding base. One end of the threaded rod is fixedly connected to a handle.

[0008] In one example, the lifting assembly includes a support plate, which is fixedly connected to a base. The support plate has a square through slot, in which a slider is slidably connected. The slider is fixedly connected to a horizontal plate. An electric push rod is fixedly connected to the lower surface of the base, and the telescopic rod of the electric push rod is fixedly connected to the slider.

[0009] In one example, a rubber pad is fixedly connected to the lower surface of the extrusion plate.

[0010] In one example, the adsorption and fixation assembly includes a square shell fixed to the lower surface of a placement plate, the square shell covering a through hole, a square cylinder fixedly connected to the lower surface of the square shell, the square cylinder communicating with the square shell, a mounting plate fixedly connected inside the square cylinder, a servo motor fixedly connected to the lower surface of the mounting plate, a threaded rotating rod fixedly connected to the spindle of the servo motor, and a piston slidably connected inside the square cylinder, the threaded rotating rod passing through the piston and threadedly connected to the piston.

[0011] In one example, the base has a square notch, a support plate is fixedly connected to the side wall of the base, a first motor is fixedly connected to one side of the support plate, a gear is fixedly connected to the main shaft of the first motor, and a rack is fixedly connected to the lower surface of the placement plate.

The placement plate is movable, and the position of the through hole corresponding to the foil is adjusted to change the adsorption and fixing position. The double fixing from top to bottom is more stable and avoids the installation position of the foil and the tab, so as to avoid obstructing or hindering the assembly process.

[0014] Secondly, by setting up gears and racks, the movement of the placement plate is driven by the first motor to rotate the gears, which in turn drive the placement plate to move laterally through the rack, adjusting the position of the through hole. The first motor is also a servo motor, which can drive the placement plate to slide back and forth, saving manpower. Attached Figure Description

[0022] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0023] like Figures 1-4 As shown in the figure, an embodiment of this utility model proposes a fixing device for assembling lithium battery foil sheets, including a base 1. A lifting component 2 is provided on the upper surface of the base 1, and an adjustable fixing device 3 is provided on the lifting component 2. A placement platform 4 is fixedly connected to the upper surface of the base 1. A square through groove is provided on the upper surface of the placement platform 4 and the upper surface of the base 1. A placement plate 5 is slidably connected to the side wall of the placement platform 4. The placement plate 5 passes through the placement platform 4 and has a row of through holes on its surface. An adsorption fixing component 6 is provided on the lower surface of the placement plate 5. A multi-layered lithium battery foil sheet is placed in the square through groove area above the placement plate 5. The foil sheet in the middle is fixed by the side wall of the square through groove. The foil is positioned such that its lower surface is fixed by the adsorption and fixing component 6 below the placement plate 5, and its upper surface is fixed by the compression of the adjustable fixing device 3. The lifting component 2 provides downward pressure. The placement plate 5 is movable, and the position of the through hole corresponding to the foil can be adjusted to change the adsorption and fixing position. The position of the adjustable fixing device 3 above can also be adjusted. The upper surface is fixed by the adsorption and fixing component 6 below, and the upper surface is fixed by the adjustable fixing device 3 in the position where it is not installed. The double fixing from the top and bottom makes it more stable and avoids the installation positions of the foil and the tabs, thus avoiding obstruction and hindrance to the assembly process.

[0024] Specifically, the adjustable fixing device 3 includes a horizontal plate 31, which is fixedly connected to the lifting assembly 2. A fixing seat 32 is fixedly connected to one side of the horizontal plate 31. The fixing seat 32 has a through groove, and a sliding seat 33 is slidably connected in the groove. A vertical rod 34 is fixedly connected to the lower surface of the sliding seat 33, and a pressing plate 35 is fixedly connected to the lower end of the vertical rod 34. Two vertical plates 7 are fixedly connected to the upper surface of the fixing seat 32, and a threaded rod 8 is rotatably connected between the two vertical plates 7. The threaded rod 8 passes through the sliding seat 33 and is threadedly connected to the sliding seat 33. A handle is fixedly connected to one end of the threaded rod 8. Rotating the threaded rod 8 controls the sliding seat 33 to slide, adjusting the position of the pressing plate 35. Then, the lifting assembly 2 drives the horizontal plate 31 to descend, so that the pressing plate 35 presses onto the foil for fixing. The width of the pressing plate 35 is smaller than that of the placement table 4, which allows for pressing and fixing of the foil at different positions, making it convenient to use.

[0025] Specifically, the lifting assembly 2 includes a support plate 21, which is fixedly connected to the base 1. The support plate 21 is provided with a square through slot, and a slider 22 is slidably connected in the square through slot. The slider 22 is fixedly connected to the horizontal plate 31. An electric push rod 23 is fixedly connected to the lower surface of the base 1. The telescopic rod of the electric push rod 23 is fixedly connected to the slider 22. The electric push rod 23 controls the slider 22 to slide up and down, and controls the extrusion plate 35 to descend and extrude the foil. The structure is simple and the operation is convenient.

[0026] Specifically, a rubber pad is fixedly connected to the lower surface of the extrusion plate 35 to prevent the foil from being indented by the cushioning effect of the rubber pad.

[0027] Specifically, the adsorption and fixing component 6 includes a square shell 61, which is fixed to the lower surface of the placement plate 5 and covers the through hole. A square cylinder 62 is fixedly connected to the lower surface of the square shell 61, and the square cylinder 62 is in communication with the square shell 61. An installation plate 63 is fixedly connected inside the square cylinder 62, and a servo motor 64 is fixedly connected to the lower surface of the installation plate 63. A threaded rotating rod 65 is fixedly connected to the spindle of the servo motor 64. A piston 66 is slidably connected inside the square cylinder 62. The threaded rotating rod 65 passes through the piston 66 and is threadedly connected to the piston 66. When adsorbing and fixing the multi-layer foil, the servo motor 64 drives the threaded rotating rod 65 to rotate, thereby controlling the piston 66 to descend, so that suction is generated in the through hole to adsorb and fix the foil above. When contact fixing occurs, the servo motor 64 simply reverses, the suction disappears, and the foil is released. It is simple and flexible to use.

[0028] Specifically, the base 1 has a square notch, and the support plate 9 is fixedly connected to the side wall of the base 1. The first motor 10 is fixedly connected to one side of the support plate 9. The main shaft of the first motor 10 is fixedly connected to the gear 11. The lower surface of the placement plate 5 is fixedly connected to the rack 12. The rack 12 and the gear 11 mesh through the square notch. The movement of the placement plate 5 is driven by the first motor 10 to rotate the gear 11, and the rack 12 drives the placement plate 5 to move laterally to adjust the position of the through hole. The first motor 10 is also a servo motor 64, which can drive the placement plate 5 to slide back and forth, saving manpower.

[0029] Working principle: The multi-layered lithium battery foil is placed in the square through-slot area above the placement plate 5. The first motor 10 drives the gear 11 to rotate, which drives the placement plate 5 to move laterally through the rack 12, adjusting the position of the through hole and changing the fixed position of the lower surface. Then, the servo motor 64 drives the threaded rotating rod 65 to rotate, which in turn controls the piston 66 to descend, so that suction force is generated in the through hole to adsorb and fix the foil above. The threaded rod 8 is rotated, which controls the sliding seat 33 to slide, adjusting the position of the extrusion plate 35 to avoid the assembly position. The electric push rod 23 controls the slider 22 to slide up and down, controlling the extrusion plate 35 to descend and extrude and fix the foil.
