Embodiment Construction

[0021] Relevant detailed description and technical content of the present invention, now just explain as follows with respect to matching drawing:

[0022] see Figure 1A and Figure 1B As shown, they are respectively the structure and partial enlarged cross-sectional schematic diagram of an embodiment of the present invention. The present invention provides an ultrasonic demoulding device for demoulding a contact lens 41. The ultrasonic demoulding device includes an ultrasonic wave demoulding device. Oscillator 10, a transmission part 20 and a mould, this mould, in this embodiment, refers to a first mold 31 at this, and can be with a second mold 32 (shown in Figure 3A ) corresponding to meshing. The ultrasonic oscillator 10 is used to generate an ultrasonic wave, and the shock-transmitting member 20 is connected between the ultrasonic oscillator 10 and the first mold 31, and the ultrasonic wave is transmitted from the ultrasonic oscillator 10 to the first mold 31. On a mol...

Abstract

The invention discloses an ultrasonic demoulding device and a method for using the ultrasonic demoulding device to make a contact lens; the ltrasonic demoulding device comprises an ultrasonic oscillator, a shock transmitting part and a mould, the shock transmitting part is arranged between the ultrasonic oscillator and the mould, the ultrasonic oscillator is used for generating an ultrasound, the ultrasound is transmitted to the mould by the shock transmitting part to make the mold produce a shock to enable the contact lens attached to the mould to remove from the mould; the method includes a mould pressing step, a curing step, a mould opening step and a demoulding step using the ultrasonic demoulding device for shock demoulding. Accordingly, the ultrasonic demoulding device and the method method for making the contact lens have the advantages that the demoulding time is very short, the production speed is improved, and after demoulding the contact lens is in a dry state, and the accuracy of a subsequent detection process can be improved.

Description

technical field [0001] The invention relates to a contact lens manufacturing process, in particular to an ultrasonic demoulding device used in the manufacture of contact lenses and a method for manufacturing contact lenses. Background technique [0002] Due to the development of science and technology, various information products with display screens are ubiquitous, such as TVs, desktop computers, notebook computers, tablet computers, smart phones, etc., which greatly increases the chances of modern people to use their eyes at close range for a long time. Let the eyes have little chance to relax and rest, so that the population of myopia is increasing day by day, not only the number of people who wear glasses increases, but also the number of people who choose to wear contact lenses is also increasing. It has become a trend for contact lenses to change the color of the eyes, which has greatly increased the demand for contact lenses, and the manufacturing technology of conta...
