[0002] In the field of glass vacuum coating, glass coating is a process of continuously coating the substrate in the coating equipment. The existing ITO (indium tin oxide) coating substrate fixtures have a wide spacing, which is not suitable for clamping smaller curved glass. When producing curved glass, the position of the fixture needs to be adjusted, which is time-consuming. Moreover, due to the inappropriate size, it is easy to cause the distance between the glasses to be too large, resulting in an increase in the diffraction effect of the coating.

[0003] The utility model patent with application publication number CN114481061B discloses a glass continuous ITO coating equipment, including a continuous coating cabin, a coating chamber is arranged in the middle of the continuous coating cabin, and the cabins on both sides of the continuous coating cabin are arranged symmetrically along the left and right sides of the coating chamber. Both ends of the continuous coating cabin are provided with substrate loading and unloading door grooves that communicate with the inside and outside, so as to realize circular transportation inside the continuous coating cabin. During the transportation process, the transfer rack enters and exits the vacuum transition cabin to realize the switching of the transfer rack between the negative pressure continuous coating cabin and the external environment. However, the equipment cannot quickly adjust the spacing between the glasses, which is very inconvenient in actual use.

[0004] Therefore, improvements are made to address the above problems. Utility Model Content

[0021] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. In addition, the technical features involved in each embodiment of the utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] Embodiment 1

[0023] The utility model protects a curved glass ITO coating tool, such as Figure 1 , Figure 3 As shown, it includes at least two relatively parallel vertical poles 1, a cross bar 2 is arranged between the vertical poles 1, and the cross bar 2 is fixedly connected with a plurality of upper clamps 2-1 and lower clamps 2-2, the upper clamp 2-1 is a circular hole structure, the upper clamp 2-1 is screwed with a spring buckle 2-3, the spring buckle 2-3 is an annular structure, the spring buckle 2-3 fits with the top surface of the product 4 and is used to prevent the product 4 from displacement or tilting during processing, one end of the top of the product 4 is sleeved in the annular structure of another spring buckle 2-3, and the position of the product 4 is adjusted and fixed by the hardness of the spring itself to prevent it from falling, the lower clamp 2-2 is an integrally formed metal groove, the lower clamp 2-2 is connected to the bottom slot of the product 4 and is used to fix the product 4, a plurality of positioning blocks 3 are arranged on the outside of the vertical pole 1, which are used to fix the vertical pole 1 during erection, and the positioning block 3 is provided with a plurality of threaded holes 3-1, which are used to be threadedly connected with the vertical pole 1.

[0024] As a preferred embodiment, the distance between two adjacent positioning blocks 3 is equal, which is beneficial to keep the various sections of the upright pole 1 under balanced force when it is vertically fixed.

[0025] As a preferred embodiment, the number of the upper clamp 2-1, the lower clamp 2-2 and the spring buckle 2-3 are at least two.

[0026] As a preferred embodiment, the lower clamp 2-2 is made of any one of stainless steel, aluminum alloy and zinc alloy, has high toughness and strength, is light, easy to install and corrosion-resistant.

[0027] As a preferred embodiment, the spring buckle 2-3 is a carbon spring, a low manganese spring, a silicon manganese spring, a chrome vanadium spring or a leaf spring, which is cheap, has convenient raw material sources, and has good fatigue resistance and impact resistance.

[0028] During processing, products 4 of different sizes and different curvatures are placed in sequence, and the upper and lower ends of the product 4 are aligned with the crossbar 2 arranged laterally on the vertical pole 1, respectively, to ensure the stability and accuracy of the product during processing. The top of the product 4 is clamped by an annular spring buckle 2-3 connected by screws of at least two circular hole-shaped upper clamps 2-1, and the bottom is fixed by at least two integrally formed lower clamps 2-2. This upper and lower double fixing method can effectively prevent the product from being displaced or tilted during processing, thereby ensuring the quality and consistency of the coating. The top of the product 4 fits with the surface of the spring buckle 2-3, and one end of the top of the product 4 is sleeved in the annular structure of the other spring buckle 2-3, which helps to adjust and fix the position of the product 4 to prevent it from falling. When replacement is required, loosen the spring clip 2-3 and take out the product 4. With the help of the flexibility of the spring clip 2-3, it can be directly clamped to the next product 4 of different size and curvature, and the bottom is directly fixed to the lower clamp 2-2, so that the ITO coating process can be carried out without adjusting the interval size, saving the adjustment time when changing the model, simplifying the operation process, and making the processing smoother and more efficient.

[0029] Embodiment 2

[0030] The utility model also protects a curved glass ITO coating tooling equipment, such as Figure 2 As shown, it is installed with the curved glass ITO coating tooling fixture described in Example 1.

[0031] As a preferred embodiment, a plurality of positioning holes 5 - 1 are opened on both sides of the surface thereof, which are used for plugging and installing with the positioning block 3 and cooperating with each other to fix the curved glass ITO coating tooling fixture.

[0032] As a preferred embodiment, the distances between two adjacent positioning holes 5 - 1 are equal, so as to be installed and fixed one by one with the positioning blocks 3 , and at the same time play an aesthetic role.

[0033] During processing, the staff first moves the vertical pole 1 to set up the curved glass ITO coating tooling fixture on the equipment 5 as a whole. The overall design avoids the tedious process of installing individual components one by one, and significantly shortens the equipment preparation time. The positioning blocks 3 with equal spacing are fixed in the positioning holes 5-1 in turn to ensure the stability and accuracy of the tooling fixture during the coating process. At the same time, products 4 of different sizes and curvatures are still fixed on the curved glass ITO coating tooling fixture and move with it. The product 4 does not need to be disassembled or reinstalled, which reduces the complexity of the operation. After the processing is completed, the formed product 4 can also be moved away from the production line with the curved glass ITO coating tooling fixture as a whole to ensure the position stability of the product 4 during the coating process and reduce the coating quality problems caused by position changes. Thereby, the process of ITO coating can be directly carried out on the coating equipment without disassembling the product 4, and the process of equipment erection, product 4 processing and offline can be completed more conveniently, which greatly simplifies the operation steps, saves the adjustment time of disassembly and replacement, and improves production efficiency.
