Description

Technical Field

[0001] The utility model relates to the technical field of electrochromic technology, in particular to a coating fixture. Background Art

[0002] The electrochromic device consists of five layers from top to bottom, namely: the first glass substrate, the first EC film, the electrolyte, the second EC film and the second glass substrate. Because EC devices have special requirements for conductivity, tin-doped indium oxide conductive glass (ITO) or fluorine-doped tin oxide conductive glass (FTO) is often used as the glass substrate, and the color-changing film is plated on the surface of the glass substrate.

[0003] When coating a large volume of glass, the glass substrate needs to be fixed in a supporting jig first, and then transferred to the coating equipment for coating. The coating equipment is provided with a slide rail, and the coating jig is provided with a guide rail. The guide rail and the slide rail slide together to facilitate the coating jig to flow in the length direction of the slide rail. When coating a large volume of glass, the glass needs to be fixed. However, if the coating jig in the prior art fixes the glass too tightly, it is easy to cause the glass to bend or even break. If the coating jig fixes the glass too loosely, the glass will fall and cannot be clamped, which seriously affects production. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a coating jig, which is convenient for providing an adjustable clamping force to a glass substrate, thereby reducing damage to the glass substrate while ensuring clamping reliability.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] Coating fixtures, including

[0007] A coating frame, wherein two sliding supports are slidably connected to the coating frame, the two sliding supports are arranged opposite to each other, and when any one of the sliding supports slides, the two sliding supports move closer to each other or farther away from each other;

[0008] a first fixture, the first fixture being mounted on one of the sliding supports;

[0009] The second clamp is installed on the other sliding support, the first clamp and the second clamp are arranged opposite to each other, and a clamping space is formed between the first clamp and the second clamp. When the first clamp and the second clamp are squeezed, the first clamp and / or the second clamp can generate elastic deformation to reduce the clamping force on the glass substrate.

[0010] Furthermore, a clamp base is provided on one of the sliding supports, and a mounting groove is provided on the clamp base, and the mounting groove is used to install the first clamp, and the first clamp includes a first clamping portion and two supporting portions, the first clamping portion is U-shaped, and the supporting portions are arranged on both sides of the first clamping portion to form an M-shaped structure, and the first clamp is engaged with the first clamp through the two supporting portions, and when the first clamping portion is squeezed, the first clamping portion drives the two supporting portions to rotate relative to each other.

[0011] Furthermore, the second clamp includes a second clamping portion and two connecting portions, the second clamping portion is formed between the two connecting portions, the connecting portion is detachably connected to the corresponding sliding support, an installation angle is formed between the connecting portion and the second clamping portion so that an installation gap is formed between the connecting portion and the sliding support, and when the second clamping portion is squeezed, the connecting portion elastically bends so that the installation gap is reduced.

[0012] Furthermore, the second clamping portion is configured to be V-shaped or U-shaped.

[0013] Furthermore, the materials of the first clamp and the second clamp are both set to be elastically deformable materials.

[0014] Furthermore, the coating frame is arranged vertically, and the first clamp is arranged below the second clamp.

[0015] Furthermore, a guide rail is fixedly connected to the coating frame, the guide rail is slidably matched with the slide rail, and the surface of the guide rail exposed to the slide rail is set to be a rough surface.

[0016] Furthermore, the rough surface is coated or protrusions are provided on the rough surface to increase the roughness.

[0017] Beneficial effects of the utility model:

[0018] 1. The utility model provides a first clamp and a second clamp. When the first clamp and the second clamp are squeezed, the first clamp and / or the second clamp can produce elastic deformation so that the glass has space to move, thereby reducing the clamping force on the glass substrate. The glass will not be broken by clamping too tightly, nor will the glass be clamped too loosely so that the glass cannot be clamped. The clamping reliability is high.

[0019] 2. By setting the surface of the guide rail exposed to the slide rail as a rough surface, the sputtered material in the coating chamber can adhere to the rough surface and move out of the coating chamber as the guide rail moves, thereby avoiding the sputtered material from remaining in the coating chamber and improving the coating quality.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] It should be noted that when a component is referred to as being "fixed to" another component, it may be directly on the other component or there may also be a component centered. When a component is considered to be "connected to" another component, it may be directly connected to the other component or there may also be a component centered. When a component is considered to be "set on" another component, it may be directly set on the other component or there may also be a component centered. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0030] like Figure 1As shown, a coating jig of the present embodiment includes a coating frame 1, a first clamp 2 and a second clamp 3. The coating frame 1 is arranged vertically, and the first clamp 2 is arranged below the second clamp 3. A guide rail 11 is fixedly connected to the coating frame 1, and the guide rail 11 slides with the slide rail so that the coating jig can move along the slide rail. Considering that the smooth surface cannot make the sputtered film layer adhere during the coating process, so that the sputtered material remains in the coating cavity, resulting in poor coating quality. Therefore, in the present application, the surface of the guide rail 11 exposed to the slide rail is set as a rough surface. The rough surface is coated or a protrusion is set on the rough surface to increase the roughness. By setting the surface of the guide rail 11 exposed to the slide rail as a rough surface, the material sputtered in the coating cavity can adhere to the rough surface and move out of the coating cavity with the movement of the guide rail 11, so as to avoid the sputtered material remaining in the coating cavity and improve the coating quality.

[0031] Two sliding supports 12 are slidably connected to the coating frame 1. The two sliding supports 12 are arranged opposite to each other, and when any sliding support 12 slides, the two sliding supports 12 move closer to or farther from each other. The first clamp 2 is installed on one of the sliding supports 12, and the second clamp 3 is installed on the other sliding support 12. The first clamp 2 and the second clamp 3 are arranged opposite to each other, and a clamping space is formed between the first clamp 2 and the second clamp 3. When the first clamp 2 and the second clamp 3 are squeezed, the first clamp 2 and / or the second clamp 3 can produce elastic deformation to reduce the clamping force on the glass substrate. The materials of the first clamp 2 and the second clamp 3 are both set to elastic deformable materials.

[0032] Please refer to Figures 1 to 3 , a clamp base 4 is provided on one of the sliding supports 12, and a mounting groove 401 is provided on the clamp base 4, and the mounting groove 401 is used to install the first clamp 2. In this embodiment, a mounting hole 402 is provided on the clamp base 4, and the clamp base 4 and the sliding support 12 are connected by bolts or screws. The first clamp 2 includes a first clamping portion 201 and two supporting portions 202. The shape of the first clamping portion 201 is U-shaped, and the first clamping portion 201 is used to clamp the glass substrate. The supporting portions 202 are provided on both sides of the first clamping portion 201 and make the first clamp 2 form an M-shaped structure. The first clamp 2 is engaged with the first clamp 2 through the two supporting portions 202. When the first clamping portion 201 is squeezed, the first clamping portion 201 drives the two supporting portions 202 to rotate relative to each other.

[0033] When installing the first clamp 2 and the clamp base 4, the two support parts 202 are squeezed, and the distance between the two support parts 202 can be reduced, so that the first clamp 2 can be easily inserted into the installation groove 401. After releasing the grip, the two clamping parts are reset to be clamped in the clamp base 4, which is convenient for installation. At the same time, when the glass substrate squeezes the first clamping part 201, the two support parts 202 rotate relative to each other to produce deformation, thereby avoiding a sudden increase in the clamping force and thus avoiding damage to the glass substrate.

[0034] Please refer to Figure 1 , 4 and Figure 5 The second clamp 3 includes a second clamping portion 301 and two connecting portions 302, wherein the second clamping portion 301 is formed between the two connecting portions 302. The second clamping portion 301 is configured to be V-shaped or U-shaped to facilitate cooperation with the glass substrate. The connecting portion 302 is bent relative to the second clamping portion 301, and as shown in FIG. Figure 1 The connecting portion 302 is detachably connected to the corresponding sliding support 12 through a fastener, and an installation angle is formed between the connecting portion 302 and the second clamping portion 301 so that an installation gap is formed between the connecting portion 302 and the sliding support 12. When the second clamping portion 301 is squeezed, the connecting portion 302 elastically bends so that the installation gap is reduced.

[0035] Working principle:

[0036] When the coating jig involved in the present application is used to clamp the glass substrate, one end of the glass substrate is placed in the first clamping portion 201 of the first clamp 2, and the other end of the glass substrate is placed in the second clamping portion 301 of the second clamp 3. The two sliding supports 12 are close to each other to clamp and fix the glass substrate. At this time, the connecting portion 302 is elastically bent due to being squeezed, and the second clamping portion 301 moves in a direction close to the corresponding sliding support 12. Combined with the shapes of the first clamp 2 and the second clamp 3, damage to the glass substrate is avoided.

[0037] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
