Technical Field

The utility model relates to a spraying tool especially relates to a crooked glass's of screen anti fingerprint membrane of 3D spraying tool in batches.

Background

The anti-fingerprint mold spraying is to spray the anti-fingerprint mold on the mobile phone glass by adopting an automatic spraying machine, the prior anti-fingerprint film spraying process is directed at the plane glass, the plane glass can be sprayed by one whole block after being placed flatly, and the spraying is processed after the spraying, so that the waste rate of the spraying material is low. With the market of 3D curved screen glass, the 3D curved screen glass is independent one by one, so that batch integral spraying cannot be carried out. In the 3D curved screen glass spraying process, because the batch spraying can not be carried out, the single spraying is adopted, the labor intensity of workers is high, and the spraying material is seriously wasted. In addition, a serious problem is also caused in the spraying process, because the upper end and the lower end of the glass edge curved surface are not sealed, the spraying material is very easy to spray the back surface of the 3D curved screen glass, the problem of excessive plating is caused, the adhesion is insufficient after the back surface is coated with glue in the later period, the curved screen glass cannot be effectively bonded, and the yield is reduced. Therefore, the back of the curved screen glass needs to be cleaned additionally, and the glass surface is easy to scrape and is troublesome to treat due to the fact that the spraying materials are difficult to clean and the surface of the glass is easy to scrape in the cleaning process.

Detailed Description

The present invention will be further explained below.

Example 1: referring to fig. 1, 2 and 3, the batch spraying jig for the anti-fingerprint film of the 3D curved screen glass comprises a bottom die 1, wherein a plurality of groups of male dies 2 are arranged on the bottom die 1, the male dies 2 are distributed on the bottom die 1 in an array manner, one 3D curved screen glass can be placed on each male die 2 through the male dies 2 distributed on the bottom die 1 in an array manner, so that the batch spraying operation of the 3D curved screen glass is realized, the waste of spraying materials is greatly reduced, the production efficiency is improved, the male dies 2 are matched with the back shape of the 3D curved screen glass, the shape design of the male dies 2 is matched with the inner concave surface of the 3D curved screen glass, the 3D curved screen glass can be conveniently placed, due to the curved surface design of the 3D curved screen glass in the spraying process, the transverse displacement is easy to occur in the spraying process, the upper end and the lower end of each male die 2 are provided with the stop bars 3, and the stop bars 3 are used for, play the effect of sheltering from bent screen glass of 3D about both ends terminal surface simultaneously, avoid the appearance of excessive plating phenomenon, make the bent screen glass's of 3D back obtain fine sheltering from the protection, the spraying material can not be sprayed the bent screen glass back of 3D, shelves strip 3 and terrace die 2 all with die block 1 integrated into one piece, overall structure is firm, can not appear sheltering from not tight problem because of not hard up causing.

The convex die 2 is square, arc angles are rounded on four sides of the convex die 2, particularly, the arc degrees of the left side and the right side of the convex die 2 need to be attached to the curved surfaces of two sides of the 3D curved screen glass, the 3D curved screen glass can be stably buckled on the convex die 2, and the problem of excessive plating on the left side and the right side of the 3D curved screen glass is solved. The fillet on the upper side and the lower side is convenient for blanking, and the problem that the upper side and the lower side of the 3D curved screen glass are damaged due to friction between the 3D curved screen glass and the stop strip 3 caused by inclination in the taking process is avoided.

The distance between the stop bars 3 at the upper end and the lower end of the convex die 2 is the length of the 3D curved screen glass to be sprayed, and the height of the convex die 2 is the height of the concave surface at the back of the 3D curved screen glass to be sprayed, so that the convex die 2 is tightly attached to the 3D curved screen glass in shape and structure. The design of shelves strip 3 has realized the centre gripping at crooked screen glass upper and lower both ends of 3D and has sheltered from, avoids the crooked screen glass upper and lower both sides of 3D to appear the excessive plating problem.

The upper male die 2 and the lower male die 2 which are adjacent share the stop bar 3, the design of the stop bar 3 is reduced, the arrangement is more compact, and a certain gap is left between the left male die 2 and the right male die 2 which are adjacent for facilitating small materials.

The bottom die 1, the stop strips 3 and the male die 2 are all made of PVC materials, the PVC materials are low in cost, light in weight, smooth in surface and not prone to damage glass, the processing and manufacturing are easy, and the tool die is quite suitable for being used as small glass parts such as mobile phone glass.

The bottom die 1 is installed on the spraying tool table, and the anti-fingerprint die can be sprayed on the mobile phone glass through the automatic spraying machine after being installed on the spraying tool table.

As a preferable scheme, in the design process of the male die 2, considering that some glass products are light and are easy to displace in the spraying process, the groove 4 is formed in the upper surface of the male die 2, the bottom of the groove 4 is provided with a vacuumizing hole, the vacuumizing hole penetrates through the bottom die 1, and the male die 2 can generate certain adsorption force by vacuumizing from the bottom die 1, so that the glass to be processed is tightly adsorbed on the male die 2, and the installation stability of the 3D curved screen glass is improved.

The anti-fingerprint film batch spraying jig for the 3D curved screen glass provided by the utility model is introduced in detail, and specific examples are applied to explain the principle and the implementation of the utility model, and the description of the above embodiments is only used for helping to understand the method and the core idea of the utility model; while the invention has been described in terms of specific embodiments and applications, it will be apparent to those skilled in the art that numerous variations and modifications can be made without departing from the spirit and scope of the invention as defined in the appended claims.
