Title:
DEVICE FOR LIGHT GUIDE FILM PRODUCT PROCESING
Document Type and Number:
WIPO Patent Application WO/2020/177785
Kind Code:
A3
Abstract:
A device for light guide film product processing, comprising a material discharge apparatus (1) used for conveying a first light guide film (9); a dot array processing apparatus (3), a cooling apparatus (4), a cutting apparatus (5), a waste material collection apparatus (6), and a product collection apparatus (8), which are sequentially arranged along the conveyance direction of the first light guide film (9); and a linkage controller (2); the dot array processing apparatus (3) transfer-prints a dot array onto both sides of the first light guide film (9); the cooling apparatus (4) is used for cooling the first light guide film (9) following dot array processing; the cutting apparatus (5) is used for cutting the cooled first light guide film (9); and the waste collection apparatus (6) is used for rolling a second light guide film (10), the second light guide film (10) being the material remaining after the first light guide film (9) is cut to form a light guide film product; the included angle formed between the direction in which the second light guide film (10) is rolled and conveyed and the direction in which the first light guide film (9) is conveyed is α, where α＞0. The linkage controller (2) programmably controls the dot array processing apparatus (3), the cooling apparatus (4), and the cutting apparatus (5) to start and stop, so as to achieve an integrated production process comprising: one-step formation of the dot arrays on both sides of the light guide film, light guide film product cutting, and excess material recovery. The present invention can effectively increase light guide film product quality, expand product types, and improve product processing efficiency.
