Abstract

The invention discloses a drying device for optical polishing wafers. The device comprises a drying box, a box door is arranged on one side of the drying box, a plurality of drying motors are arrangedon the other side of the drying box, a heating fan is arranged on the top of the drying box, an air guiding pipe is arranged on one side of the heating fan, the bottom of the air guiding pipe penetrates through the drying box to be connected with an air collecting tube located on the inner top of the drying box, the bottom of the air collecting tube is provided with a plurality of air outlet pipes, a plurality groups of drying tubes are arranged in the drying box, and the end, away from a rotary shaft is fixed to the inner wall of the drying box through a bearing seat. The device has the advantages that the design is reasonable, and the use is convenient; compared with a traditional oven, the drying efficiency of the device is effectively improved, the scratching caused by stacking of theoptical polishing wafers is effectively avoided, and therefore the processing quality of the optical polishing wafers is effectively ensured.

Description

technical field [0001] The invention relates to the technical field of polishing sheet processing, in particular to a drying device for optical polishing sheets. Background technique [0002] The resins used in optical polishing sheets are basically thermoplastic resins. But it cannot use the general thermoplastic resin molding processing method, but draws on the processing method of powder metallurgy cold pressing sintering molding. First, put a pre-prepared molding material of a certain weight into the molding cavity of the die, and directly apply pressure to the molding material in the molding cavity through the pressure rod, and press it into a dense cylindrical optical polishing sheet. Then they are placed in batches in an oven for heating and curing to make optically polished sheets. However, the existing ovens not only have poor drying efficiency, but also tend to scratch the polished surface due to the stacking of the front and rear sheets, which greatly affects ...
