Lens cutting machine with decelerating function

Abstract

The invention discloses a lens cutting machine with a decelerating function. The lens cutting machine comprises a rack. The rack is provided with a clamp for fixing a lens, a cutter, a transverse-moving assembly enabling the cutter to get close to or get away from the clamp, and a lifting assembly driving the cutter to rise and fall; the cutter is connected with the transverse-moving assembly through the lifting assembly; the lifting assembly comprises a third power piece driving the cutter to rise and fall; the third power piece comprises a cylinder body and a pushing rod penetrating throughthe cylinder body; the bottom of the pushing rod is connected with the cutter; a first baffle is arranged on the top of the pushing rod; and a decelerator capable of elastically abutting against the first baffle is arranged on the side, facing the cylinder body, of the first baffle and connected with the cylinder body. The lens cutting machine has the function of enabling the cutter to fall in a decelerating mode, so that impact force to the lens is reduced, and cracks and notches on the lens are reduced.

Description

technical field [0001] The invention relates to lens processing equipment, in particular to a lens cutting machine with deceleration function. Background technique [0002] In the prior art, the lens usually needs to be cut into small pieces first, and then further processed. The existing cutting method is generally to lay the lens flat, and then press the lens from above to keep the lens fixed, and then move the cutting knife along a straight line and The lens applies pressure so that the lens is cut into two pieces. [0003] In order to improve the cutting efficiency of the lens, a cutting machine has been developed, which can lower the cutting knife. After the cutting knife touches the lens, the cutting knife moves in a straight line to cut. Since the cutting edge of the cutting knife is generally a sharp point, The downward movement of the cutting knife is generally promoted by an air cylinder or a hydraulic cylinder. The moving speed of the cutting knife is fast. When ...

[0003] In order to improve the cutting efficiency of the lens, a cutting machine has been developed, which can lower the cutting knife. After the cutting knife touches the lens, the cutting knife moves in a straight line to cut. Since the cutting edge of the cutting knife is generally a sharp point, The downward movement of the cutting knife is generally driven by an air cylinder or a hydraulic cylinder. The moving speed of the cutting knife is fast. When the cutting knife touches the lens, it will have an impact on the lens. The lens is prone to cracks or gaps, which will affect the surface quality of the lens.
