Press-key manufacturing method and apparatus thereof

Abstract

The invention provides a key-press manufacturing method and the device thereof. The method comprises the following steps: (1), materials for forming key-presses are poured into a die; (2) a film covers the die; (3) the film is used for printing, that is, a printing layer is arranged on the film; and (4) a location lamella is jointed, that is, the film provided with the printing layer is jointed with the location lamella. The device comprises the film, a key set and the printing layer; the film is a perspective layer; the key set is arranged on the film and comprises a plurality of key-press sheets; a connecting sheet is connected between bottoms of adjacent key-press sheets; and the printing layer is arranged on the bottom surface of the film and used for forming fonts and symbols opposite to the key-press sheets. Therefore, the key-press device has the advantages of simple and easy and convenient manufacture, so as to facilitate volume production operation; furthermore, the key-press device can specifically reduce equipment costs, shorten operation time and increase production volume, and then positively promotes the manufacturing economic benefit and the product competitiveness of the key-press device.

Description

Technical field: [0001] The invention relates to a button structure technology, especially a button with high manufacturing yield and good quality, which is easy and convenient to manufacture, is especially suitable for mass production, and can actively improve its manufacturing economic benefits and product competitiveness. Manufacturing method and device thereof. Background technique: [0002] It is known to make buttons such as mobile phones, home phones, computers, personal digital assistants (PDAs), etc., such as Figure 1 to Figure 2D As shown, the manufacturing process is to form a button sheet 80 by plastic injection molding. The button sheet 80 includes a plurality of button sheets 81. The button sheet 81 is connected with a frame 83 by a material bone 82. The button sheet 80, the top surface of its button sheet 81 is provided with a sprayed laser engraving layer 84 and the bottom surface is provided with a printing layer 85, and the sprayed laser engraved layer 84 ...

AI Technical Summary

Problems solved by technology

Although the second customary technique can also be made into a finished button device, it still has the same defects as the above-mentioned equipment and high manufacturing cost, does not meet the economic benefits of manufacturing, and easily causes the button sheet to be pasted in a wrong position or pasted off. Covering the three surfaces of the button sheet 94 and forming the connection of the button sheet 94 during injection molding, the overall process has the problem of lowering the yield rate. Therefore, the second conventional technique is: film printing -> stretch molding -> cutting -> In-mold injection -> Die-cutting to form keypads -> Arrangement of keypads on key trays -> Gluing keypads to rubber sheets -> Finished keypad devices These manufacturing methods are also not ideal process design

[0004] Therefore, how to thoroughly improve the lack of economic benefits such as poor production efficiency, high cost equipment, and low yield of the known button manufacturing method is a key direction that the industry or wise people should explore and make breakthroughs.

[0005] In view of the lack of production and the unsatisfactory fact in the process design of the known button manufacturing method, the inventor of this case started to develop its solution based on years of experience in R&D and design in this industry, hoping to develop a better The button manufacturing method and its device with manufacturing economic benefits and product competitiveness to promote the development of this industry, and then the present invention has been produced after a long time of conception
