Technical Field
The utility model belongs to components and parts are anchor clamps field for manufacturing particularly, belongs to selectivity film forming anchor clamps field, and further speaking belongs to the two-sided film forming anchor clamps field of selectivity.
Background
In the production process of components, such as chip resistors, chip attenuators, chip modules, and the like (hereinafter referred to as products), in order to meet the requirements of different electrical leading-out or actual installation and application, the requirements of a conductor metal film or an insulation protective layer film (hereinafter, the formation of the conductor metal film or the insulation protective layer film is referred to as a film) on an electrical leading-out end face are very different. For example, the most common chip resistors generally perform full-end-face metal film formation from two opposite end faces, and the film formation process is usually realized by coating silver on the whole end face, sputtering the whole end face or directly dipping a single face in a slurry manner, and meanwhile, because each end face is respectively formed with films in a grading manner, the production efficiency and the quality consistency are influenced to a certain extent. However, some components, such as a chip attenuator having an input terminal, an output terminal, and a ground terminal, only half area of the local metal is required to form a film on each of two opposite end surfaces, and the local film formation cannot be achieved by a conventional integral end surface film formation process.
Disclosure of Invention
In order to solve the problems of local film forming on the end face of a product, low production efficiency and poor quality consistency, a vacuum sputtering thin film process or a screen printing slurry and sintering thick film process is adopted, and patterned masks of different processes are combined, so that conductor metal films or insulating protective layer films with different patterns can be selectively formed on the end face of the product according to requirements. According to this principle, the utility model provides a two-sided film forming anchor clamps of product, this anchor clamps include: bottom plate, bottom surface figure mask device, center, locating plate, bottom surface figure mask device is fixed in on the fixed frame of bottom surface figure mask, the center is fixed in on the bottom surface figure mask device, surface figure mask device is fixed in on the center, the locating plate is located in the center and under the surface figure mask device, and be fixed in on the bottom plate.
The bottom surface pattern mask device comprises a bottom surface pattern mask and a bottom surface pattern mask fixing frame, and the bottom surface pattern mask is fixed on the bottom surface pattern mask fixing frame.
The surface pattern mask device comprises a surface pattern mask and a surface pattern mask fixing frame, wherein the surface pattern mask is fixed on the surface pattern mask fixing frame.
The pattern mask is made of a metal foil or an organic thin film.
The pattern mask made of metal foil or organic film is directly fixed on the pattern mask fixing frame and used for selectively sputtering the film in vacuum.
The pattern mask made of the metal foil or the organic film is fixed on a screen firstly, and then the screen fixed with the pattern mask is fixed on the pattern mask fixing frame and used for selectively screen-printing slurry and sintering a thick film.

The metal wire mesh is a stainless steel wire mesh, and the organic wire mesh is a nylon wire mesh.
By adopting the technical scheme, the product double-sided film forming clamp can solve the problems of local film forming on the end face and low production efficiency. Compared with the traditional end face film forming treatment of leading-out ends, the clamp has the advantages that different patterns can be designed according to needs through the pattern masks, the flexibility is high, the front end face and the back end face are fixed on the clamp through the bottom pattern mask device and the surface pattern mask device, in the process of end face film forming of a product, the mask device does not need to be taken down, the product needing to form a film on the other end face needs to be reassembled, the end face with the special patterns in the opposite direction can be directly subjected to film forming treatment through the whole overturning clamp, and the production efficiency and the quality consistency are greatly improved.
According to different graphic mask devices, the process of vacuum sputtering film or silk-screen printing paste and sintering can be adopted to realize the local film formation or the integral film formation of the end face so as to meet the requirements of different product designs.

Detailed Description
Taking a double-sided film forming fixture for manufacturing a strip attenuator series product (hereinafter referred to as a strip product for short) as an example, the structure of the fixture is described as follows by combining fig. 1:
1) a bottom plate: the metal blocking net frame, the middle frame and the positioning plate are fixed on the bottom plate and play a role of a clamp base. As shown in fig. 2 (a).
2) Patterning the metal mask: and manufacturing a required pattern metal mask according to different patterns by using a stainless steel metal foil through a photoetching process or a laser etching process.
3) Fixing a graphic mask: the pattern mask fixing frame is used for fixing pattern metal masks with different patterns on the pattern mask fixing frame directly or through a silk screen to form a bottom pattern mask device and a surface pattern mask device respectively. The bottom surface pattern mask device is fixed on the bottom surface of the bottom plate through screws, and the surface pattern mask device is fixed on the middle frame, so that the requirement of double-sided film forming of different patterns is met. As shown in fig. 2 (b).
3) A middle frame: the thickness of the middle frame can be changed according to the width size of the strip-shaped product, and the middle frame is used for fixing the strip-shaped product with determined size in the middle frame and fixing the middle frame on the bottom plate. As shown in fig. 2 (c).
4) Positioning a plate: the strip-shaped products are positioned in the middle frame, when a certain amount of products are discharged, the strip-shaped products need to be fixed by the positioning plate in the longitudinal direction, the products are prevented from collapsing, and after the products are fully discharged, the positioning plate is fixed on the bottom plate by screws.
