Abstract

The invention discloses a heat transfer printing device for the end face of a light guide plate. The heat transfer printing device comprises a clamping structure and a heat transfer printing structure. The clamping structure comprises a light guide plate platform, a supporting frame and a clamp used for fixing the light guide plate to the light guide plate platform, the supporting frame is arranged on the light guide plate platform, and the clamp is movably arranged on the supporting frame. The heat transfer printing structure comprises a locating box, a heat transfer printing wheel and a heat transfer printing platform, the heat transfer printing wheel is arranged on a fixing frame on one side of the locating box, a microstructure unit is attached to the surface of the heat transfer printing wheel, a heating element is arranged in the heat transfer printing wheel, the other side of the locating box is connected with the heat transfer printing platform through an elastic structure, and the bottom surface of the locating box is connected with the heat transfer printing platform in a sliding mode through a sliding rail. The light guide plate platform corresponds to the heat transfer printing wheel in position. The technical scheme that in the prior art, a microstructure unit is inconvenient to produce on the end face of the light guide plate is solved through contact between the heat transfer printing wheel and the end face of the light guide plate, and the heat transfer printing device is easy to operate and high in rate of finished products and lowers the production cost greatly.

Description

technical field [0001] The invention relates to a heat transfer technology, in particular, a heat transfer device and a transfer method for an end face of a light guide plate. Background technique [0002] The current light guide plate manufacturing technologies are mainly divided into four types: injection molding, printing, hot pressing, and inkjet. Among them, only injection molding can manufacture end-face microstructure light guide plates through molds, and the other three methods cannot be manufactured. However, the production efficiency of injection molding is low, and the equipment investment cost is very high. [0003] At present, another end surface processing method is to process the microstructure on the long stainless steel block. The microstructure on the stainless steel block is transferred to the light guide plate through the contact between the long stainless steel block and the end surface of the light guide plate. This processing method has a great impact ...
