Embodiment Construction

[0031] see figure 2 and Figure 4 The numerical value units marked in are all (mm).

[0032] see figure 1 , the main steps of producing HF-0568 keys by UV transfer printing key production process:

[0033] (1) Pre-drying: unwind the whole roll of PC sheet and pre-dry it with infrared rays. The pre-drying condition is 120°C / 8min;

[0034] (2) Oil pressure: punching edge of PC sheet, punching size is 180×140mm;

[0035] (3) PET film printing: discharge the product, discharge (put the product printing surface), then print varnish and add sulfur (120°C / 0.5H), then print adhesive, add sulfur (120°C / 1H);

[0036] (4) PU molding: dispensing glue on the PU production mold 13, covering with PET film, pressing and rolling, passing through a UV light curing machine (20±5S, temperature is 55±5°C), and demoulding;

[0037] (5) Printing: The operation process is to discharge the product → discharge (put the product printing surface) → hollow character → add sulfur (60°C / 0.5H) → black ...

Abstract

The invention discloses a production process of a uv transfer printing molded key device, which includes the following steps of: solidifying glue in a mold cavity by ultraviolet light of a uv lamp and adhering the glue to a film; positioning a key structure on a double-sided glue assembly base according to a positioning hole, with the front face of the key structure facing upwards; tearing out a D-type double-sided release paper glue layer, and positioning the release paper glue layer facing downwards on the key structure according to the positioning hole; tearing sponge off the release paper, and placing the sponge with the glue layer facing downwards and a laser etched production brochure number facing upwards into a sponge assembly base; positioning the key stuck with the D-type double-sided glue and the sponge facing downwards on the assembly base according to the positioning hole; tearing off C-type double-sided glue yellow release paper, positioning transparent release paper facing downwards on the assembly base according to the positioning hole with automatic turnover and assembly, and flat-pressing and tightly compressing the C-type double-sided glue on the back of the key; and after silica gel is prepared, sheathing the silica gel on the base by using a pressing fixture, flat-pressing and tightly compressing the silica gel on a punching machine for one time, and putting the base on an ejection fixture for ejecting out the molded key device.

Description

technical field [0001] The invention relates to the field of communication tool spare parts, and specifically relates to the production process of UV transfer printing ultra-thin buttons. Background technique [0002] At present, the production technology of ordinary mobile phone keys is familiar to most enterprises. Therefore, only by continuously introducing new technologies and new processes can the competitiveness of enterprises be increased. The production process of UV transfer printing ultra-thin buttons is still blank in the domestic market. The difficulty of the process is the development of new materials: 1. UV glue, 2. Adhesives; machinery and equipment: play a decisive role in the realization of the process. At present, most manufacturers are troubled by this, and the products cannot achieve the expected results. The products are not effective. A lot of bubbles mean that the molded product has serious shrinkage; mold development: another factor in the realizatio...
