Problems solved by technology

In the prior art, the lens is fixed on the carrying mechanism with a clamping piece, and when coating, the coating particles reach the surface of the lens from all directions, and the clamping piece that fixes the lens will cause a shielding effect on the edge of the lens, making the lens The thickness of the surface coating layer is not uniform
In addition, the design of the opening on the carrier mechanism of the prior art to accommodate the lens needs to match the size of the lens. When the size of the lens changes, all the carrier mechanism used in the original process needs to be replaced, which reduces the production efficiency during mass production.

Embodiment Construction

[0012] The carrying mechanism described in the present invention is suitable for coating or transporting the lens, and it is connected to a vacuum pump through a valve.

[0013] Please refer to FIG. 1 , the carrying mechanism described in the preferred embodiment of the present invention includes a hollow box body 1 and a plurality of suction heads 2 .

[0014] Please also refer to FIG. 2 , the hollow box 1 includes a body 11 , a cover 12 , an air outlet 13 and a plurality of suction nozzles 14 . The main body 11 is a semi-closed metal box structure, which has a working surface 110 and a side surface 112 adjacent to the working surface 110 . The cover 12 is a metal plate, which is welded together with the main body 11 to form a closed metal box, and a hollow cavity is formed between the main body 11 and the cover 12 . The air inlet 13 is a tubular body, which is disposed on the side surface 112 and communicates with the hollow space between the body 11 and the cover 12 . The...

Abstract

A mechanism of bearing the weight, of which characteristics is including: A medium altitude box and many soil receiver suction end, this medium altitude box has a medium altitude chamber, and this medium altitude box is designed with many suction mouth and a suction gas mouth that communicate with this medium altitude chamber, correspondingly this soil receiver suction end and this suction mouth match tightly. The mentioned mechanism of bearing the weight can adsorb lens on the soil receiver suction end by negative pressure, make transport of lens be more convenient, and plating film thickness that is obtained in the process of plating film is more uniform.

Description

【Technical field】 [0001] The present invention relates to a carrying mechanism, in particular to a carrying mechanism applied to vacuum coating and transportation. 【Background technique】 [0002] Various optical lenses are widely used in built-in digital cameras of portable electronic devices such as mobile phones, notebook computers and personal digital assistants. The optical lens of the digital camera usually adopts a small-sized lens to meet the requirement of a small-volume design of the digital camera. [0003] In order to meet the various optical requirements of digital cameras, it is usually necessary to coat a layer of optical film on the lens, such as anti-reflection film, infrared cut filter film, etc. In the coating process, such as the vacuum coating process, a carrying mechanism is usually required to carry the lens to be coated. In the prior art, the lens is fixed on the carrying mechanism with a clamping piece, and when coating, the coating particles reach ...
