Automatic down-cutting device for optical glass sheet

Abstract

The invention discloses an automatic breaking device for an optical glass plate material, and belongs to the technical field of optical glass production. The automatic breaking device mainly solves the problems that the labor intensity is high, the glass fracture surface quality is difficult to control and an existing breaking device is easy to damage glass and a clamping device in manpower breaking. The device comprises a transport mechanism, a detection mechanism, a longitudinal moving mechanism, a scribing mechanism, a heating mechanism, a cooling mechanism and a pressing and breaking mechanism, wherein the transport mechanism comprises a roller conveying platform and a belt conveyor; the detection mechanism comprises an encoder and a first cylinder; the longitudinal moving mechanism comprises longitudinal linear guide rails, a first ball screw and a first servo motor; the scribing mechanism comprises a second ball screw, a second servo motor, transverse linear guide rails and a diamond scribing knife; the heating mechanism comprises a heating rod and a second cylinder; the cooling mechanism comprises a sponge body and a third cylinder; and the pressing and breaking mechanism comprises a stamping cylinder and a pressing block. According to the automatic breaking device, automatic breaking of the optical glass plate material can be realized according to a set length, the fracture surface quality is good, and the breaking length is accurate.

Description

technical field [0001] The invention belongs to the technical field of optical glass production, and in particular relates to an automatic lower cutting device for optical glass sheets. Background technique [0002] Optical glass blanks are divided into sheets and primary parts, among which optical glass sheets dominate in quantity and are the basic optical materials for subsequent processing such as cutting and secondary molding. In production, it is necessary to divide the optical glass sheet with a certain width and thickness after molding and rough annealing treatment, according to the length required by the market. Traditional segmentation methods are done manually by humans. A feeding platform is set at the outlet of the mesh-belt traction furnace. When the rough annealing and residual temperature glass sheet is moved to the platform, the operator uses the pre-made sample ruler and diamond knife to move along the In the direction of glass movement, draw a scratch on ...

Problems solved by technology

The Chinese patent with the publication number CN104445905A discloses a device for scribing and cutting optical glass strips. Synchronous movement to achieve horizontal scribing, heating, cooling and lower breaking, but in the actual application process, since the glass sheet pulled out from the traction furnace not only has a longitudinal displacement along the traction direction, but also inevitably has a lateral swing displacement , the connection method of the air claw and the sliding guide sleeve hinders the lateral movement of the glass sheet, which is easy to damage the glass and the clamping device. At the same time, the natural gas intermittent ignition heating method is difficult to operate, and the heating effect is not easy to control. In addition, because it only uses The traditional limit switch positioning is used, and the position control in the process of breaking down is not accurate, which will inevitably affect the quality of breaking down of the glass sheet.
