Problems solved by technology

This traditional protection method will not only cause a waste of tape cost in mass production, but also time-consuming, inefficient, and hidden dangers
[0003] When spraying the outer frame of the printed part, if the protective tooling is made, it is generally made of plastic or rubber materials. The production of this kind of tooling must first make a mold. Not only the cost of the mold is high, but the tooling is not easy to fix. Generally, there are two layers of upper and lower layers, which is not easy. tightly sealed
Metal or hard plastic can also be milled into tooling on the machine tool, which costs more and also has the problem of sealing and fixing

Embodiment 1

[0050] Use EVA material to make protective tooling. It is best to choose a hardness plate with a hardness of 38 degrees or more, which is easy to process on a milling machine. If the hardness is too low, it is easy to deform and the size is not accurate. During processing, the size of the upper and lower layers of the tooling is designed according to the size of the outer frame 1 of the printed part 2. The upper convex platform 3 provided on the upper layer of the tooling and the lower concave platform 6 arranged around the lower layer of the tooling are fitted and sealed, and the printed part is just in the middle. The size processing of the embedded outer frame 1 of 2, the upper layer through hole 5 adapted to the upper surface of the printed part 2 is arranged on the upper layer of the tooling, and the lower through hole 8 adapted to the lower surface of the printed part 2 is arranged on the lower layer of the tooling; The inner edge 4 of the upper through hole and the inner...

Embodiment 2

[0054] For a printed part 2 with a small size and an outer frame 1, multiple printed parts 2 can be integrated on a set of tooling, which is more convenient and quicker. see Figure 8 to Figure 11 , is an example of integrating two printed parts 2 into a set of tooling. The upper layer of the tooling and the lower layer of the tooling are provided with two through holes respectively, each pair of through holes on the upper and lower layers corresponds to a printed part 2, and the two lower middle grooves 9 provided on the lower layer of the tooling correspond to the outer frame 1 of a printed part 2 respectively , a certain distance is spaced between each through hole, and the upper boss 3 and the lower concave platform 6 of the frock are the same as in embodiment 1, and they are fitted together; the size design of each through hole and the use method of the integrated frock are the same as in embodiment 1 . The multiple printed parts 2 integrated by the integrated tooling c...

Abstract

The invention discloses an outer frame protection tool and method during spray coating of printed parts. The tool comprises a tool upper layer and a tool lower layer; the tool upper layer and the toollower layer are detachably connected, and the printed parts are placed between the tool upper layer and the tool lower layer; an upper layer through hole is formed in the tool upper layer, and whether an upper layer middle groove is arranged is determined according to requirements; a lower layer through hole and a lower layer middle groove are formed in the tool lower layer, and the middle grooveis used for containing the outer frame; and the inner edge of the upper layer through hole and the inner edge of the lower layer through hole extend out of the inner side of the inner edge of the upper side and the inner side of the inner edge of the lower side of the outer frame by 0-2 mm; the tool upper layer and the tool lower layer adopt an anti-static EVA material. The tool has the advantages that the tool is light and handy, has tenacity and does not damage products, operation is simple, fixing in unnecessary, labor and materials are saved, and at the same time quality and efficiency ofthe product are improved; meanwhile, cost of the whole tool is low, anti-static property and reusable property are achieved, simplicity, efficiency and practicality are realized; and the tool is particularly suitable for batch production and spray coating protection of electronic products which are complex in structure and not easy to protect.

Description

technical field [0001] The invention belongs to the field of electronic product protection manufacturing, and relates to an outer frame protection tool and method for spraying printed parts. Background technique [0002] In the electronic product manufacturing industry, when spraying printed parts with frames, tapes are usually used to protect the outer frames that do not need to be sprayed, and the protective tapes are removed after painting. This traditional protection method will not only cause a waste of adhesive tape cost during mass production, but also be labor-intensive, inefficient, and have hidden risks. [0003] When spraying the outer frame of the printed part, if the protective tooling is made, it is usually made of plastic or rubber materials. The production of this kind of tooling must first make a mold. Not only the cost of the mold is high, but also the tooling is not easy to fix. Generally, there are two layers of upper and lower layers, which is not easy. ...
