Description

Technical Field

[0001] This utility model relates to the field of coating technology, and more specifically, to a coating fixture for the entire surface without obstruction. Background Technology

[0002] Generally, coating processes define certain ineffective coating areas around the perimeter. Current practices use fixtures to clamp the product at its corners or perimeter, creating areas that are obscured and cannot meet coating requirements; these are generally referred to as ineffective coating areas. Areas not obscured by the fixture are considered effective coating areas. When the entire coating surface is defined as an effective coating area, fixture clamping becomes insufficient. Utility Model Content

[0003] In view of the problems existing in the prior art, the purpose of this utility model is to provide a full-surface coating fixture without obstruction.

[0004] To solve the above problems, the present invention adopts the following technical solution.

[0005] A full-surface coating fixture without obstructing edges includes:

[0008] The side of the product that faces away from the high-temperature back-stretching film is the coated side.

[0009] Compared with the prior art, the present invention has at least the following beneficial effects:

[0010] The product can be fixed in the cavity of the fixture body by using a back-stretching high-temperature film and adhesive layer. The fixing method is simple and convenient. Since the cavity can completely accommodate the product, the coating surface of the product is completely open and not blocked, thus achieving full-surface coating.

[0011] Preferably, a protective film is attached to the coated surface.

[0012] Preferably, the coated surface is higher than the side of the fixture body that is away from the back-stretched high-temperature film.

[0013] Preferably, the edge of the cavity facing away from the high-temperature back-stretching film is chamfered.

[0014] Preferably, the portion of the cavity near the back-stretched high-temperature film is recessed to form a recessed step, and the product is accommodated in the cavity and rests against the recessed step.

[0015] Preferably, the back-stretching high-temperature film is provided with protrusions that are embedded in the cavity and adhered to the product.

[0016] Preferably, the cavities are provided in a plurality of forms and are distributed in a rectangular array on the fixture body. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] refer to Figure 1-3 A non-obstructed edge full-surface coating fixture includes: a fixture body 1 and a back-stretching high-temperature film 2. The fixture body 1 has at least one through-hole cavity 11 for completely accommodating a product 3. The back-stretching high-temperature film 2 is disposed on one side of the fixture body 1, and an adhesive layer 21 for bonding and fixing the product 3 is disposed on the side near the cavity 11. The side of the product 3 facing away from the back-stretching high-temperature film 2 is the coating surface 31.

[0027] Understandably, the fixture body 1 is a base component, which can be a plate structure or a frame structure, but is not limited to these. The cavity 11 is a structure used to accommodate the product 3, and it can be set to be square or circular, depending on the formation of the product 3, but is not limited to these. If the cavity 11 is set to be square, its length and width must be greater than the length and width of the product 3; if it is set to be circular, its diameter must be greater than the diameter of the product 3, so as to ensure that the product 3 can be completely accommodated in the cavity 11 without obstruction. The adhesive layer 21 on the back-stretched high-temperature film 2 can be fully covered, that is, the back-stretched high-temperature film is bonded and fixed to the fixture body 1 by the adhesive layer 21; the adhesive layer 21 can also be partially set on the back-stretched high-temperature film 2 corresponding to the cavity 11, and other parts without the adhesive layer 21 can be integrally set with the fixture body 1, threadedly connected, snap-fit ​​connected, magnetically connected, etc., but is not limited to these.

[0028] With this setup, the product 3 can be fixed in the cavity 11 of the fixture body 1 by using the back-pull high-temperature film 2 and the adhesive layer 21. The fixing method is simple and convenient. Since the cavity 11 can completely accommodate the product 3, the coating surface 31 of the product 3 is completely open and not blocked, thus achieving full-surface coating.

[0029] In some embodiments, a protective film 4 is attached to the coated surface 31. Here, the protective film 4 is attached before coating, which can effectively prevent external dust and dirt before coating, keeping the coated surface 31 clean.

[0030] In some embodiments, reference Figure 4 The coating surface 31 is higher than the side of the fixture body 1 that faces away from the high-temperature film 2. This can be controlled by setting the thickness of the fixture body 1, that is, setting the thickness of the fixture body 1 to be slightly thinner than the thickness of the product 3. In this way, interference of the fixture body 1 with the coating surface of the product 3 can be minimized during coating.

[0031] In some embodiments, the edge of the cavity 11 facing away from the high-temperature film 2 is chamfered 111. Here, the chamfer 111 can be a rounded corner or a flat corner, etc. In this way, the chamfer 111 can widen the edge of the cavity 11, and can also avoid the interference of the fixture body 1 on the surface coating of the product 3.

[0032] In some embodiments, the portion of the cavity 11 near the back-stretched high-temperature film 2 is recessed to form a recessed step 12, and the product 3 is accommodated within the cavity 11 and rests against the recessed step 12. Here, the recessed step 12 can be integrally formed with the cavity 11, or it can be detachably set within the cavity 11 by means of bonding, snap-fitting, or other methods. The purpose of setting the recessed step 12 is to raise the product 3. Therefore, the height difference between the coated surface 31 of the product 3 and the surface of the fixture body 1 can be controlled by controlling the thickness of the recessed step 12, ensuring the consistency of the coating effect.

[0033] Furthermore, the high-temperature back-stretching film 2 is provided with protrusions 22 that are embedded in the cavity 11 and bonded to the product 3. Understandably, due to the recessed step 12, there will be a difference in coverage between the bottom of the product 3 and the bottom of the fixture body 1. The protrusions 22 compensate for this height difference, thus bonding and fixing the product 3 in place.

[0034] In some embodiments, a plurality of cavities 11 are provided and distributed in a rectangular array on the fixture body 1. In this way, the multiple cavities 11 are arranged in an orderly manner, which can make full use of the area of ​​the fixture body 1.

[0035] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
