Description

Technical Field

[0001] This utility model relates to the field of battery production technology, and in particular to a coating pad and battery coating equipment. Background Technology

[0002] The quality of electrode coating not only directly affects the overall capacity of the battery pack, but also the voltage, power and lifespan of the entire battery cell. The coating machine process determines the quality of electrode coating.

[0003] The coating head of a coating machine generally includes an upper die and a lower die. A coating pad is held between the upper die and the lower die. Existing coating pads usually include vertical sections, and a discharge port is formed between the two vertical sections. The gap width between the two vertical sections is the coating width of the coating head.

[0004] In existing coating machines, the distance between two adjacent vertical sections is fixed, making it impossible to adjust the coating width. When coating electrodes of different widths, it is often necessary to replace coating pads of different sizes, thus requiring multiple coating pads to meet production needs. In addition, the existing vertical sections do not have a thinning structure, which cannot effectively thin the coating edge area of ​​the electrode, affecting the coating quality of the electrode and even causing bulging of the electrode in subsequent production processes.

[0005] Therefore, it is necessary to design a coating pad and battery coating equipment that can both adjust the coating width and improve the coating quality of the electrode sheets.

[0006] The above information is provided as background information only to aid in understanding this disclosure and does not constitute an assertion or admission that any of the above content can be used as prior art relative to this disclosure. Utility Model Content

[0042] Example 1

[0043] In view of the aforementioned defects in existing coated gaskets, the applicant, based on years of extensive practical experience and professional knowledge in the design and manufacture of such products, and in conjunction with the application of theoretical principles, actively conducted research and innovation in order to create a solution that overcomes the defects in the existing technology and makes the coated gasket more practical. After continuous research, design, and repeated prototype production and improvement, this utility model with real practical value has finally been created.

[0044] Please refer to Figures 1 to 4 This utility model provides a coating pad, including a pad body 1 and an adjusting piece 2.

[0045] The gasket body 1 has a discharge port 101. An adjusting plate 2 can be slidably installed on the gasket body 1 to adjust the discharge width of the discharge port 101. Generally, an adjusting plate 2 is provided on each side of the discharge port 101. The adjusting plate 2 can slide relative to the gasket body 1, thereby changing the length of the obstruction of the discharge port 101, and thus changing the actual slurry discharge width of the discharge port 101, that is, better adjusting the coating width.

[0046] In this embodiment, a stepped groove 201 is provided on the side edge of the adjusting plate 2 near the discharge port 101, and a thinning chamfer 202 is formed at the end of the stepped groove 201 near the outer side of the discharge port 101. The stepped groove 201, in conjunction with the thinning chamfer 202, can adjust the uniformity of the slurry, adjust the slurry flow direction, and eliminate dead zones in the slurry flow. The thinning chamfer 202 can adjust the thinning thickness and width of the coating edge area, improve the coating quality, and avoid problems such as bulging edges on the electrode sheet in subsequent processing.

[0047] It should also be noted that the thinning chamfer 202 can be adjusted according to the actual required coating thickness and electrode thinning width. The angle between the bevel of the thinning chamfer 202 and the top extension surface of the adjusting plate 2 is greater than 45°. Figure 2 As shown, the top extension surface is the horizontal plane where the top surface of the adjusting plate 2 is located. The angle between the inclined surface of the thinning chamfer 202 and the top extension surface of the adjusting plate 2 is greater than 45°, which can help control the slurry flow rate and thus improve the thinning effect.

[0048] Preferably, the thinning chamfer 202 has dimensions of 1mm × 2mm. That is, the 2mm portion of the thinning chamfer 202 is located on the side as shown below. Figure 2 The edge line near the discharge port 101 shown in the figure, the edge where 1mm is located is the edge line near the top surface.

[0049] Optionally, the gasket body 1 has a horizontal portion 11 and a vertical portion 12 fixedly connected to the horizontal portion 11, and the horizontal portion 11 and the horizontal portion 12 are integral structures. The vertical portion 12 is provided with a sliding groove 13 with an opening facing the discharge port 101; the adjusting plate 2 is provided with a sliding extension 21 slidably installed in the sliding groove 13, and the sliding extension 21 and the sliding groove 13 are sealed and slidably connected.

[0050] On the one hand, the sliding groove 13 and the sliding extension 21 limit the sliding direction of the adjusting piece 2, thereby preventing the adjusting piece 2 from becoming misaligned after sliding. On the other hand, the sealed sliding connection between the sliding extension 21 and the sliding groove 13 effectively prevents slurry leakage. Preferably, an elastic element is installed in the sliding groove 13, and the elastic sealing element fully fills the inner hole formed by the sliding extension 21 and the sliding groove 13. The elastic sealing element can achieve a better sealing effect and further reduce the possibility of slurry leakage.

[0051] Optionally, two vertical sections 12 are provided at intervals; each vertical section 12 has an adjusting plate 2 slidably mounted on it, and the two adjusting plates 2 are symmetrically arranged about the discharge port 101. In this embodiment, the position of each adjusting plate 2 is individually adjustable. After the adjusting plate 2 is adjusted to the appropriate position, it is necessary to fix the adjusting plate 2 and the gasket body 1 to prevent the adjusting plate 2 from being pressed back during the coating process.

[0052] Optionally, the depth of the stepped groove 201 is equal to half the thickness of the adjusting piece 2.

[0053] Optionally, the adjusting plate 2 further includes an adjusting part 22 fixedly connected to the sliding extension 21, the adjusting part 22 being slidably mounted on the top surface of the vertical part 12; the adjusting part 22 is provided with a scale. Specifically, the user can adjust the position of the adjusting plate 2 according to the scale, thereby ensuring that the coating width is the actual width, reducing errors and simplifying the adjustment process.

[0054] Optionally, a force adjustment hole 2201 is provided at the end of the adjustment part 22 away from the stepped groove 201. When the mold head is closed, the force adjustment hole 2201 allows workers to quickly and accurately change the position of the adjustment piece 2 using tools, without having to adjust the position of the adjustment piece 2 after the mold is opened, which helps to improve adjustment efficiency and thus improve production efficiency.

[0055] Optionally, the sliding groove 13 is parallel to the transverse portion 11.

[0056] Optionally, a clearance hole 1301 is provided at the bottom corner of the sliding groove 13. The clearance hole 1301 can avoid the end corner of the adjusting piece 2, so as to prevent the sliding extension 21 from not being able to fully enter the sliding groove 13 due to the protrusion at the end corner.
