Description

Technical Field

[0001] The present application relates to the field of film coating technology, and in particular to a film coating jig and a film coating device. Background Art

[0002] During the coating process on battery substrates, the existing technology involves sequentially loading a mask plate and a substrate into a groove on a loading platform, then placing the loading platform into a coating chamber to coat the substrate.

[0028] Hereinafter, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings.

[0029] The present invention provides a coating fixture for Figure 1 The structural diagram of the coating plate 100 is shown in FIG. Figure 1 As shown, the coating plate 100 includes a coating plate body 110 , and a first surface of the coating plate body 110 is provided with a plurality of coating grooves 120 . Figure 2 The schematic diagram of the structure of the coating fixture provided by the embodiment of the present application is shown. Figure 2and Figure 3 As shown, the coating fixture includes a bonding plate 210 and a plurality of elastic members arranged on the second surface of the bonding plate 210 ; the number, position and telescopic length of the elastic members are adapted to the coating groove 120 .

[0030] In the embodiment of the present application, a coating jig is combined with the coating plate 100 to form a coating device. Figure 4 A schematic structural diagram of the coating equipment provided in an embodiment of the present application is shown. Figure 5 A schematic structural diagram of the coating device provided by an embodiment of the present application from another angle is shown. Using the coating device for coating can improve the coating efficiency and coating effect while ensuring the quality of the substrate.

[0031] In the embodiment of the present application, the second surface of the laminating plate 210 of the coating jig is laminated to the first surface of the coating plate 100, and the elastic member is pressed on the substrate and the mask to apply a certain elastic force, which can limit the relative movement between the substrate and the mask. Based on this, during the coating process, when the rotation rate is slightly increased, it can still be ensured that there is no relative movement between the substrate and the mask, and the coating can be performed at a rotation rate, thereby improving the coating efficiency. The elastic member in the coating jig in the embodiment of the present application is a metal spring, which does not damage the substrate after applying the elastic force. Therefore, the coating jig provided in the embodiment of the present application can improve the coating efficiency and coating effect while ensuring the quality of the substrate.

[0032] It can be understood that the length, width and other dimensions of the bonding plate 210 can be adapted to the dimensions of the coating plate body 110. The length and width of the bonding plate 210 can be equal to the length and width of the coating plate body 110. Even the planar shape of the bonding plate 210 can be the same as the planar shape of the coating plate body 110, that is, the cross-sectional shape on the horizontal plane. For example, the coating plate body 110 has a handle, and the bonding plate 210 can also be provided with a handle. The planar shape of the bonding plate 210 is the same as the planar shape of the coating plate body 110, which can facilitate the bonding operation between the bonding plate 210 and the coating plate 100 while being conveniently placed in the coating cavity.

[0033] In one example, the number of the elastic members is the same as the number of the coating grooves 120 , and one elastic member corresponds to one coating groove 120 to apply elastic force to the mask and substrate in the corresponding coating groove 120 .

[0034] In one example, when the bonding plate 210 can be bonded to the coating plate body 110, the elastic member is pressed near the center of the coating groove 120 to press on the substrate and the mask from the center to avoid damage to the substrate or the mask as much as possible.

[0035] In one embodiment, the elastic member is a metal sheet 220, which includes a fixed portion 221, a bent portion 222 and a bonding portion 223. The fixed portion 221 is fixed to the second surface of the bonding plate 210; the bent portion 222 is bent at 20°-70° with the fixed portion 221, and the bonding portion 223 includes at least a bonding surface parallel to the bonding plate 210.

[0036] The metal sheet 220 can be fixed firmly to the bonding plate 210 , and the metal sheet 220 has uniform elastic force and appropriate size, and its flat bonding surface is not likely to cause damage to the substrate.

[0037] The fixing portion 221 can be fixed to the bonding plate 210 by a hinged connection or a threaded connection. The bending of the bent portion 222 allows the bonding surface to move up and down, and can be squeezed and flattened when encountering resistance, rather than being pressed down rigidly, further ensuring the quality of the substrate and mask.

[0038] In one embodiment, the bent portion 222 includes one or more bends. The multiple bends of the bent portion 222 allow the bent portion 222 to flatten layer by layer when pressed, thus withstanding the elastic forces applied in various scenarios.

[0039] In one example, the bent portion 222 is bent only once and becomes flat once squeezed, leaving less room for rebounding onto the substrate, thereby failing to ensure that the substrate in each coating groove 120 is subjected to elastic force.

[0040] Therefore, the embodiment of the present application can ensure that the bent portion 222 rebounds onto the substrate after being squeezed by the multiple bending design of the bent portion 222, thereby improving the qualified rate of the coating.

[0041] In one embodiment, the bending angles of the multiple bends increase in a direction away from the bonding plate 210. The larger the bending angle, the flatter the surface. At the bonding surface, the surface is bent into a bonding surface and acts on the substrate.

[0042] Bending can be understood as bending into an "L"-shaped structure. For example, starting from the laminated plate 210, bending downward along the vertical direction and then bending horizontally is the first bend; continuing to bend downward along the vertical direction and then bending horizontally is the second bend, and so on. In the process of verifying the vertical downward direction, it will tilt downward, and the angle of the vertical plane relative to the horizontal plane is the bending angle.

[0043] The multiple bends allow the metal sheet 220 to exert downward pressure on the substrate while having space for rebounding upward.

[0044] The bending angles of the multiple bends increase successively in the direction away from the bonding plate 210, so that at the end of the metal sheet 220, the bonding surface along the horizontal direction has a larger downward force, and the position of the metal sheet 220 away from the end has a rebound force and rebound space.

[0045] In one embodiment, the length or width of the bonding surface is 1 / 8 to 1 / 3 of the coating groove 120. The length or width of the bonding surface is the area of ​​the substrate or mask that is subject to the elastic force. The larger this area, the greater the force that limits relative movement between the substrate and mask. The length or width of the bonding surface is 1 / 8 to 1 / 3 of the coating groove 120. For example, the length of the bonding surface is 1 / 8, 1 / 5, or 1 / 3 of the length of the coating groove 120, and the width of the bonding surface is 1 / 8, 1 / 4, or 1 / 3 of the width of the coating groove 120.

[0046] In one embodiment, the metal sheet 220 is made of one or more metal materials selected from the group consisting of aluminum, stainless steel, and copper.

[0047] The material of the metal sheet 220 needs to be resistant to the coating temperature and not affect the coating process.

[0048] In one embodiment, the thickness of the metal sheet 220 is 0.5-1.5 mm, for example, 0.5 mm, 0.9 mm, or 1.5 mm. The thickness of the metal sheet 220 determines the elastic force of the elastic member. Based on the need to limit the relative movement between the substrate and the mask, the required thickness of the metal sheet 220 can be driven.

[0049] The embodiment of the present application also provides another embodiment of the elastic member. In this embodiment, the elastic member includes a compression spring, and the free length of the compression spring is adapted to the depth of the coating groove 120 .

[0050] In this embodiment, the solution adopted is that a compression spring provides elastic force acting on the substrate in the coating groove 120 .

[0051] In one embodiment, the elastic member further includes a fitting sheet, which is fixed to the end of the compression spring.

[0052] The placement of the lamination sheet ensures that the spring acts on the substrate in a flat surface, preventing damage to the substrate from point contact pressure from the compression spring. This flat surface provides a more uniform downward pressure, resulting in a smaller force per unit area for the substrate under the same pressure.

[0053] In one embodiment, the laminating plate 210 is detachably connected to the coating plate 100. This facilitates separate handling of the coating plate 100 after coating, such as cleaning the coating solution. The detachable connection between the laminating plate 210 and the coating plate 100 also allows a single coating jig to be used on multiple coating plates 100, reducing the cost of manufacturing the coating jig.

[0054] In one embodiment, the laminating plate 210 is hingedly connected to the coated plate 100. For example, the laminating plate 210 and the coated plate 100 are hingedly connected at their respective sides, allowing the laminating plate 210 and the coated plate 100 to open and close from the other opposite side. Accordingly, the other side of the laminating plate 210 and the coated plate 100 may also be provided with a fixing structure, such as a rivet or bolt.

[0055] The present application also provides a coating device, comprising a coating plate 100 and a coating jig according to any of the above embodiments. The coating device, in combination with the coating jig, can improve coating efficiency and coating effect while ensuring basic quality.
