DETAILED DESCRIPTION

[0020] See also Figure 1-3 The utility model relates to a solid-state battery tab edge pressing device, comprising a base 1, a column fixed base 2, a column sliding base 3, a screw 4, a press roller column 5 and a rubber-coated roller 6. The column fixed base 2 and the column sliding base 3 are set on the base 1. The column sliding base 3 is slidably set on the base 1 through a guide rail 7. The column fixed base 2 is fixedly set on the base 1. The column fixed base 1 is first slidably set on the guide rail 7 and then fixed on the base 1 by bolts to achieve the position fixation of the column fixed base 1. The screw 4 drives the column sliding base 3 to approach or move away from the column fixed base 2. The two ends of the screw 4 are respectively supported by a screw support seat 8 and a screw fixing block 9. The screw nut 10 sleeved on the screw 4 is fixed to the bottom of the column sliding base 3. The screw 4 is equipped with an adjustment scale hand wheel 11. When the adjustment scale hand wheel 11 is turned, the screw 4 rotates to drive the screw nut 10 and the column sliding base 3 to move.

[0021] The front and rear sides of the column sliding base 3 and the column fixed base 2 are both provided with a pressure roller column 5. The two pressure roller columns 5 on the same side of the front and rear sides are connected to the rubber-coated roller 6 through a guide shaft 12. The pressure roller column 5 includes a roller column 5.1, a lower bolt bearing 5.2, an upper bolt bearing 5.3, a sliding block 5.4, a fixed block 5.5, a locking nut 5.6 and an adjusting bolt 5.7. The lower bolt bearing 5.2 horizontally passes through the roller column 5.1 and is fixed by the locking nut 5.6. The upper bolt bearing 5.3 passes through the sliding block 5.4 and is fixed by the locking nut 5.6. The sliding block 5.4 is arranged in the roller column 5.1 and fixed. The block 5.5 passes through the rolling column 5.1 and is embedded in the sliding block 5.4. The roller column 5.1 is provided with a limiting hole corresponding to the fixed block 5.5, and the sliding block 5.4 is provided with a limiting groove corresponding to the fixed block 5.5. The front and rear fixed blocks 5.5 are symmetrically arranged to prevent the sliding block 5.4 from moving left and right, thereby preventing the upper bolt bearing 5.3 from moving axially. The adjusting bolt 5.7 is arranged above the roller column 5.1. The adjusting bolt 5.7 acts on the sliding block 5.4 after passing through the roller column. A reset spring 5.8 is provided at the bottom of the sliding block 5.4. The adjusting bolt 5.7 controls the sliding block 5.4 to move up and down, thereby controlling the upper and lower bolt bearings 5.3 and 5.2 to fit completely.

[0022] The rubber-coated roller 6 is arranged between the upper bolt bearings 5.3 on the same side of the front and rear sides and between the lower bolt bearings 5.2 on the same side of the front and rear sides, and the rubber-coated roller 6 is connected to the corresponding two bolt bearings through the guide shaft 12.

[0023] A handle 13 is provided at one end of the guide shaft 12. The handle 13 is pushed to drive the guide shaft 12 to pass through the corresponding holes of the bolt bearings and the holes on the rubber-coated roller 6, so that the rubber-coated roller 6 is between the bolt bearings.

[0024] The inner side surface 5.5.1 of the fixed block 5.5 is provided with a wedge surface 5.5.1.1, and the outer side surface is provided with a tightening screw 5.9. The tightening screw 5.9 fits the wedge surface of the fixed block 5.5 with the inner side surface of the limiting hole, driving the sliding block 5.4 and the upper bolt bearing 5.3 thereon to tilt downward at an inclination angle of 1-2°. This inclination angle enables the upper and lower bolt bearings 5.3 and 5.2 to fit completely, so that the material strip will not move during the edge pressing process.

[0025] How to do it:

[0026] By turning the section scale hand wheel 11, the column sliding base 3 moves left and right, and the distance between the fixed side column pressing roller column and the sliding side column pressing roller column is adjusted to cope with the pressing of tabs of different sizes.

[0027] The two sides of the material strip that need to be pressed are respectively set between the upper and lower bolt bearings on the fixed side and between the upper and lower bolt bearings on the sliding side. The middle part of the material strip that does not need to be pressed is set between the two rubber-coated rollers 6. The pressing station structure is changed, and the pressing station is divided into left and right sides. The bolt bearing on one side is fixed, and the bolt bearing on the other side is moved by a screw rod. A scale is provided to visually show the moving distance, which is suitable for pressing the tabs of different sizes. There are two pressing passes in front and back. When pressing, the material strip passes through the front and back pressing passes. The front pass is used for preliminary pressing, and the rear press is used to press the precise size requirements.

[0028] When adjusting the edge pressing station, there is no need to adjust and assemble the bolt bearing, and the edge pressing size can be adjusted by adjusting the scale hand wheel 11 and the adjusting bolt 5.7.

[0029] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
