Description

Technical Field

[0001] The utility model belongs to the technical field of battery production tools, and particularly relates to a gasket with variable chamfers. Background Art

[0002] During the battery production process, the uniformity of the distribution of the slurry on the current collector during the coating process directly affects the electrical performance of the battery. During the coating process, the selection and use of the die head and the gasket are crucial. The die head is divided into an upper die head and a lower die head. The upper and lower die heads clamp the gasket to close. The thickness of the gasket causes a die lip gap after the die head is closed. The slurry is discharged through the die lip gap and adheres to the current collector. In the actual production process, during the process of the slurry flowing out of the die lip gap, the width of the dressing actually adhering to the current collector is greater than the opening width of the gasket. This is due to the self-flow of the slurry. The multiple width parts are called the thinning areas of the coated electrode sheet. The size and surface density of the electrode sheet thinning area directly affect the performance of the battery. Therefore, in order to control the thinning area, the top of the structure at the opening of the gasket will be cut, and the cut corner is called a chamfer. By controlling the size of the chamfer, it is possible to adapt to different coating speeds and slurry indexes. However, the gasket structure is integral and the chamfer is fixed. After design and manufacture, it is not compatible with the actual production, so it is necessary to re-adjust the size for customization. If the gasket after the second adjustment still does not meet the requirements, it still needs to be customized continuously. This greatly affects the production capacity and reduces the yield. Therefore, it is very necessary to provide a gasket with variable chamfers that has a reasonable structure, the chamfers are detachable or adjustable, can improve the thickness of the coating thinning area, can be used immediately after disassembly, and has good compatibility.

[0028] The depth of the groove 52 is 0.5 times the thickness of the chamfered gasket 4, and the width of the groove 52 is 0.5 mm.

[0029] In this embodiment, the variable chamfer is an adjustable angle gasket chamfer. The chamfered part has grooves (similar to the stripes on a utility knife that can be broken. The function of the grooves is similar to that of the grooves on a utility knife, serving a breaking function. Specifically: ① There is a detachable and adjustable chamfer at the end of the chamfer gasket. The chamfered part has a groove with a width of 0.5 mm and a depth half of the thickness of the chamfer gasket, which is used after breaking the groove. For example, a 1.5*1 chamfer becomes a 2*2 chamfer after breaking, so that the main gasket can be reinstalled and used; ② The gasket can be reused or the thickness of the coating thinning area can be improved. Due to the change of the chamfer, the thinning area will also change accordingly. In principle, the larger the horizontal chamfer, the thinner the thinning, and the larger the vertical chamfer, the thicker the thinning.

[0030] The utility model is a gasket with a variable chamfer, which effectively avoids the impact of the cycle of re-customizing the gasket on production capacity when the gasket design is incompatible with the actual on-site production. In use, the utility model adopts the structure of an adjustable angle gasket chamfer 5 or a detachable gasket chamfer 6 to change the chamfer, so that the main gasket 1 can be reused or the thickness of the coating thinning area can be improved.
