Description

Technical Field

[0001] The utility model relates to the technical field of optical lens processing, and particularly relates to a negative pressure device for optical lens processing. Background Technique

[0002] Optical lenses are important components used to control the propagation of light in an optical system. They can be classified according to different characteristics such as material, shape, the wavelength band of the transmitted light wave, and the light incidence method. The types of optical lenses include convex lenses, concave lenses, plane mirrors, and prisms, etc.

[0003] When processing optical lenses, negative pressure adsorption is usually used to adsorb and position the optical lenses, so as to ensure the stability during the processing of optical lenses. When performing negative pressure adsorption on optical lenses, an adsorption carrier seat, a connecting pipe, and a negative pressure device are usually used. When the optical lens is placed on the adsorption carrier seat, the negative pressure device extracts the gas inside the carrier seat through the pipe, so as to form a negative pressure chamber between the carrier seat and the optical lens, thereby adsorbing the optical lens.

[0004] However, when using an adsorption carrier seat, a connecting pipe, and a negative pressure device in combination to adsorb and position an optical lens, the negative pressure device needs to work continuously to avoid air leakage at the connections of the adsorption carrier seat, the connecting pipe, and the negative pressure device, resulting in the loosening of the optical lens. Usually, the negative pressure device uses a power supply to drive an air pump for operation. Furthermore, the continuous operation of the air pump will consume electricity, and it is not convenient to perform negative pressure adsorption on the optical lens manually.

The limiting spring 54 is located inside the connecting disc 56 and the mounting sleeve 51. When negatively adsorbing and positioning an optical lens, first push the connecting disc 56 upward, so that the connecting disc 56 pushes the piston 52 through the connecting rod 53 to slide to the top of the inner cavity of the mounting sleeve 51. Then release the connecting disc 56. Under the action of the limiting spring 54, the piston 52 has an elastic force to move downward relative to the mounting sleeve 51, so that the top of the inner cavity of the mounting sleeve 51 and the inside of the bearing cap 3 are in a negative pressure state, thereby negatively adsorbing the optical lens inside the bearing cap 3.
