Punching die

Abstract

The invention provides a punching die, which can realize one-time alignment and multiple punching. It is composed of upper and lower templates. The upper template includes a cover plate, a bottom plate, a positioning die nail, a permanent magnet, an etching die die and a positioning cross; They are respectively located at the four corners of the upper template, and their heads pass through the bottom plate of the upper template; there are multiple permanent magnets on the upper surface of the bottom plate of the upper template, and the permanent magnets adsorb multiple etching dies on the lower surface of the bottom plate, and the etching dies The arrangement is the same as that of the touch panel functional sheets in each row; there are four positioning crosses on the four corners of the lower surface of the bottom plate of the upper template; The positioning nails on the top are just inserted into the positioning holes of the lower mold nails of the lower template, so that the upper and lower templates are molded together, so that the etching knife mold and the positioning cross under the upper template can be in parallel contact with the surface of the lower template; the shape of the etching knife mold is consistent with The shape of the touch panel function sheet is the same. During punching, the material to be processed is placed on the lower template.

Description

technical field [0001] The invention relates to a punching die, in particular to a punching die used for manufacturing touch panel functional sheets of mobile phones and displays. Background technique [0002] As we all know, in the mobile phone manufacturing industry, when producing touch panel functional chips (sensor), such as Figure 5 As shown, a plurality of touch panel functional sheets with circuit boards and outline lines are printed on a large film material, and are made into three or more rows, and each row has multiple touch panel functional sheets. An etching die is installed on the lower working table of the punching machine. The etching die can punch the film material to form multiple touch panel functional sheets. The processed touch panel functional sheets can form a mobile phone with the glass cover. Touch screen or display touch screen panel, which is the main accessory of mobile phone screen or touch display, is also an indispensable main accessory of dis...

Problems solved by technology

Then move the film material, align the positioning crosses 16 of the second row with the positioning crosses on the etching die to complete the punching of the second row, and complete the punching of the third row and multiple rows in this way. When punching one row after another, the punching of the next row is completed by manually moving the position. This processing method is not only inefficient, but also has inaccurate processing accuracy, and it is easy to produce defective products or waste products.

Moreover, in the prior art, when processing touch panel functional sheets, a single die (4 or 5) is used for single punching, which requires repeated alignment, slow speed, low efficiency, and high scrap rate
