Embodiment Construction
[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0024] The automatic correcting device of the automatic lens molding machine includes a pneumatic mechanism, a lens mold correcting mechanism and a lens mold clamp 25.
[0025] In the pneumatic mechanism, the bearing 3 passes through the main shaft 1 and fits in a rotatable manner in the circumferential direction, and the bearing 3 is fixed on the main shaft 1 through the compression nut 2 and the compression spring 8 . The bearing 3 is covered with a cylinder housing 4 . A piston rod 5 capable of reciprocating up and down is disposed inside the cylinder housing 4 . The end cover 6 is fixedly arranged in the cylinder housing 4 by a fixed clip 7 . The taper head 12 is connected to the piston rod 5 through the taper bearing 10, and the taper bearing 10 is provided with a bearing retainer 11 installed on the lower end of the piston rod 5 to support the fixed t...

The invention discloses an automatic correction device of a lens automatic molding machine and belongs to the technical field of the lens molding machine. The device comprises a pneumatic mechanism, a lens mold correction mechanism and a lens mold clamp, wherein the pneumatic mechanism comprises a piston rod which is arranged in a cavity of an air cylinder shell and can repeatedly move up and down and is connected with a taper head through a taper bearing; the lens mold correction mechanism comprises a tensioning sleeve, a positioning rod and an aluminum suction wheel; the tensioning sleeve and the positioning rod are matched with a taper head in an inclined plane manner; a spring is sleeved between an upper positioning ring and a lower positioning ring on the positioning rod; and an O-shaped head is arranged in a groove in the lower end of the aluminum suction wheel. Defects of optical center deviation, over prism degree and the like can be automatically overcome by the device, wherein the optical center deviation after a lens is molded is caused by deviation of a closing mold when a working surface and a non-working surface of a lens mold are not parallel or the non-working surface is irregular; and the production efficiency is improved, and the production cost is reduced.
Description
technical field [0001] The invention belongs to the technical field of lens molding machines, and in particular relates to an automatic correction device of an automatic lens molding machine. Background technique [0002] Existing automatic mold-making machines, when making molds, such as the patent No. is "03229133.7", the patent name is "sheet thickness control mechanism of resin lens automatic mold-making machine", and the patent number is "200420023927.9", the patent name is "Resin The technical solution disclosed in the patent document "Lower Mold Cushioning Device of Lens Molding Machine" is that the optical center deviation after lens molding is caused by the non-parallel non-parallel or non-working surface of the lens mold or the irregularity of the non-working surface. Defects such as excessive prism degree. [0003] Therefore, it is necessary to correct a device that can automatically correct the deviation of the mold clamping caused by the non-parallel working su...
