Hot press for processing dots on surface of light guide plate

The invention relates to the technical field of plastic product production, and particularly discloses a hot press for processing dots on the surface of a light guide plate. The hot press comprises a rack, a manipulator, a transmission mechanism, a roller set, an output tape, a triaxial mechanism and a transmission supporting frame, wherein a base, a roller supporting frame and a lifting block are arranged in the rack; a hydraulic device is arranged in the roller supporting frame; the bottom of the lifting block is in contact with the top of the hydraulic device; die tapes are arranged on the outer sides of rollers in the roller set, and are made of an inert material with high rigidity, high strength, high thermal conductivity and low expansivity; the using times of the die tapes is maintained to be more than 100,000; the interiors of roller shafts are heated automatically, the temperature monitoring is carried out through a monitoring system, and the technical indexes need maintaining through accurate constant temperature; pressure required in product processing is ensured through adopting the linear scale of the product to finely adjust and set equipment distances, and two-stage adjustment of coarse adjustment and fine adjustment are realized; the technical indexes can be adjusted after the equipment distances are stably maintained.
