Description

Technical Field

[0001] The utility model relates to film coating technology and application fields, in particular to a porous film coating assembly fixture. Background Art

[0002] Screw products and other products have been widely used in a variety of electronic devices in the 3C industry. According to the design requirements of different electronic devices, screw products often need to be coated. Therefore, with the demand for production, tools to assist screw products in controlling the position or movement during the coating process, namely, coating jigs for screw products, have been created. The design and manufacture of coating jigs for screw products need to take into account factors such as the shape, size, and material of the screw products to ensure that the jig can fit the screw products tightly to avoid displacement or falling off during the coating process. However, traditional coating jigs for screw products are fixed by clamping the screw products on springs, which has the following shortcomings:

[0003] (1) The spring clamping method has low clamping efficiency and requires manpower to clamp and remove the product.

[0004] (2) The product is clamped on the fixture by a spring, and the product is subjected to the force from the spring clamping, which may damage the product's appearance.

[0005] (III) For some specific design requirements, it is necessary to use masking measures to cover other parts of the surface of the screw product where coating is not allowed, but traditional spring clamp products cannot mask the non-coated areas.

[0006] (iv) Traditional coating jigs are not equipped with drainage holes. Some liquid or gas byproducts may be produced during the coating process. If these byproducts are not discharged in time, they may have a negative impact on the coating process.

[0007] Therefore, it is necessary to design a new coating fixture for tiny products that can not only ensure that the clamping is in place, but also improve the clamping efficiency and stability. Utility Model Content

[0008] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a porous coating assembly fixture to solve one or more problems in the prior art.

[0009] To achieve the above purpose, the technical solution of the utility model is as follows:

[0010] A porous coating assembly fixture comprises a support, and the assembly fixture also comprises:

[0011] A first drainage hole, which is disposed on the surface of the support and is used for drainage during the coating process of the fixture;

[0012] A second drainage hole, which is disposed on the surface of the support and is also used for drainage during the coating process of the fixture;

[0013] The clamping holes are evenly distributed between the second drainage holes, and the clamping holes are used for clamping the coated products.

[0014] Furthermore, the clamping hole is stepped inside, the coated product is arranged in the clamping hole and a part of the product is shielded by the clamping hole.

[0015] Furthermore, the assembly fixture also includes a positioning hole, and the positioning hole is arranged at the center of the support.

[0016] Furthermore, the first drainage holes are arranged in a circular array outside the positioning hole with the positioning hole as the center.

[0017] Furthermore, the second drainage holes are arranged in a circular array outside the first drainage hole with the positioning hole as the center.

[0018] Furthermore, the number of the clamping holes decreases along the second drainage hole from an end away from the positioning hole to an end close to the positioning hole.

[0019] Furthermore, the clamping holes are staggered in a direction close to the positioning hole, so that the lines connecting the centers of each clamping hole and the centers of the positioning hole do not overlap with each other.

[0020] Furthermore, the clamping hole is arranged within the hole length range of the second drainage hole.

[0021] Furthermore, the support is circular or square.

[0022] Compared with the prior art, the beneficial technical effects of the utility model are as follows:

[0023] (i) By setting screw holes and designing the inside of the holes into a step shape, the fixing of screwed products is achieved. The screw products cover the screw holes under the action of gravity to avoid damaging the appearance of the product. At the same time, the shielding effect can be ensured, which greatly improves the clamping efficiency and saves manpower.

[0024] (ii) By setting the first drain hole and the second drain hole, the stability and quality of the coating process are ensured, the liquid and gas by-products are discharged in time, and the inside of the fixture is kept clean, dry, with uniform temperature and stable pressure.

According to the following description, the advantages and features of the utility model will be clearer. It should be noted that the drawings are in a very simplified form and all use non-precise proportions. The terms "center", "lateral", "length", "width", "height", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "side" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, rather than indicating or implying that the porous coating assembly fixture or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model, but only to facilitate and clearly assist in explaining the purpose of the implementation method of the utility model. In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, please refer to the accompanying drawings.

[0029] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings in this specification are only used to match the contents disclosed in the specification so that people familiar with this technology can understand and read them. They are not used to limit the conditions for the implementation of the utility model, so they have no substantive technical significance. Any modification of the structure, change in the proportion relationship or adjustment of the size should still fall within the scope of the technical content disclosed by the utility model without affecting the effects and purposes that can be achieved by the utility model.

[0030] The following describes the specific structure of a porous coating assembly fixture:

[0031] See also Figure 1 The porous coating assembly fixture of this embodiment includes a support 1, and the support 1 is round or square. Preferably, a round shape is selected in this embodiment.

[0032] Furthermore, the assembly jig includes a positioning hole 5, and the positioning hole 5 is arranged at the center of the support 1. The support 1 is installed on the corresponding hanger rod through the positioning hole 5 to receive the coating.

[0033] Furthermore, the assembly jig also includes a first drainage hole 2, which is arranged on the surface of the support 1. The first drainage holes 2 are arranged in a circular array outside the positioning hole 5 with the positioning hole 5 as the center. Preferably, six first drainage holes 2 are arranged in this embodiment, and the first drainage holes 2 are used for drainage during the jig coating process.

[0034] Further, the assembly jig includes a second drainage hole 3, which is provided on the surface of the support 1, and the second drainage holes 3 are arranged in a circular array with the positioning hole 5 as the center outside the first drainage hole 2. Preferably, twelve second drainage holes 3 are provided in this embodiment, and the second drainage holes 3 are preferably in a strip shape. The second drainage holes 3 are also used for drainage during the jig coating process and for reducing the weight of the jig itself.

[0035] By providing the first drainage hole 2 and the second drainage hole 3, some liquid or gas by-products generated during the coating process can be discharged in time, reducing the negative impact on the coating process, keeping the inside of the fixture clean, dry, with uniform temperature and stable pressure, thereby improving the stability and quality of the coating process.

[0036] Please continue reading Figure 1 and Figure 2 The assembly fixture is also provided with clamping holes 4, and the clamping holes 4 are evenly distributed between the two second drainage holes 3, and the clamping holes 4 are used for clamping the coated product.

[0037] Furthermore, the clamping hole 4 is stepped inside, the coated product is arranged in the clamping hole 4 and a part of the product is shielded by the clamping hole 4 for coating.

[0038] Furthermore, the number of the clamping holes 4 decreases from the end of the second drainage hole 3 away from the positioning hole 5 to the end close to the positioning hole 5, that is, from the outside to the inside. In other embodiments, the number of the clamping holes 4 can also increase or decrease as the size and shape of the support 1 changes.

[0039] Furthermore, the clamping holes 4 are staggered in the direction close to the positioning hole 5, so that the lines connecting the centers of each clamping hole 4 and the positioning hole 5 do not overlap each other, thereby forming a staggered effect, thereby avoiding the obstruction of objects between the jigs during coating and affecting the process.

[0040] Furthermore, the clamping hole 4 is arranged within the hole length range of the second drainage hole 3 , and may also exceed the hole length range of the second drainage hole 3 in other implementations.

[0041] The specific working process of a porous coating assembly fixture described in an embodiment of the utility model is described below:

[0042] The screw products to be coated are placed one by one in the clamping hole 4. The screw products cover the clamping hole 4 under the action of gravity. The thread part of the screw product can be shielded based on the step inside the clamping hole 4. After the screw product covers the entire clamping hole 4, the support 1 is installed on the corresponding hanger rod through the positioning hole 5 to receive coating. After the coating is completed, the screw product can be pushed out from the bottom of the support 1 through the clamping hole 4 and taken out.

[0043] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
