Problems solved by technology

Before the lens is cut and ground, it is necessary to determine the processing reference center, and the subsequent lens forming process needs to be carried out around the above-mentioned processing reference center. In the prior art, the above-mentioned reference center is generally marked by a pen coated with coloring material. However, this measure It is difficult to ensure that the obtained datum center is a dot, and it is difficult to guarantee its clarity and size

Embodiment 1

[0024] like Figure 1 to Figure 4 , a lens processing reference point marking equipment, including a frame 2, a lens holder 1, a tracing part and a lifting part 11, the lens holder 1 and the lifting part 11 are fixed on the frame 2, and the tracing part is fixed on the lifting part 11 on, and the tracing part can move up and down with the lifting part 11;

[0025] The point tracing part includes a needle plate 5, a point tracing needle 4 fixed on the needle plate 5, and a pressure nail 10, and there are at least two pressure nails 10, and the pressure nail 10 is fixedly connected with the needle plate 5 through an elastic member, so The description needle 4 includes a needle cylinder 3 and a needle head 6 , the needle cylinder 3 is a hollow structure provided with an ink chamber 8 inside, the needle head 6 is fixed at the lower end of the needle cylinder 3 , and the needle head 6 is partly located in the ink chamber 8 .

[0026] In this embodiment, the provided lens support 1...

Embodiment 2

[0028] This embodiment makes the following further improvements on the basis of embodiment 1: as shown in Figure 1 to Figure 4 As shown, since the thickness range of the spectacle lens is not large, and because the existing resin lenses are relatively soft, in order to avoid damage to the lens during the dotting process and simplify the structure of the lifting part 11, the lifting part 11 includes Sleeve 111, sliding shaft 114 and sliding sleeve 115, said sleeve 111 is a cylindrical structure arranged vertically, and a notch 112 along its axial direction is also provided on the sleeve 111, said sliding shaft 114 Located in the hollow structure of the sleeve 111, the sliding sleeve 115 is sleeved on the sliding shaft 114, and the sliding sleeve 115 is partly located in the gap 112, the sleeve 111 is fixedly connected to the frame 2, and the needle plate 5 is fixedly connected to the sliding shaft 114. Set 115 on. In the above structure, the sliding sleeve 115 slides along th...

Embodiment 3

[0031] This embodiment makes the following further improvements on the basis of embodiment 1: as Figure 1 to Figure 4 As shown, in the prior art, in order to protect the lens, a special suction cup for the lens is often used as a fixing device for the lens. In order to facilitate the installation of the suction cup on the present invention, that is, the lens holder 1 is connected with the suction cup, and the suction cup fixes the lens. For the installation of lenses on the present invention, the lens holder 1 is a cylindrical structure provided with round holes.

[0032] For the convenience of adding ink, adjusting the height difference between the dot needle 4 and the pressure nail 10 or replacing the dot needle 4, the syringe 3 is a cylindrical structure, the ink chamber 8 runs through the two ends of the syringe 3, and the upper end of the syringe 3 It is threadedly connected with the needle plate 5, and the needle head 6 is fixed at the lower end of the ink holding chamb...

Abstract

The invention discloses reference-point-marking equipment for lens processing. The equipment comprises a machine frame, a lens support, a point-marking part and a lifting part. Both the lens support and the lifting part are arranged on the machine frame, and the point-marking part is mounted on the lifting part, so that the former can move up and down along with the point-marking part. The point-marking part comprises a needle plate , and a point-marking needle and more than one press nails which are fixed on the needle plate. The press nails are fixedly connected with the needle plate through elastic fasteners. The point-marking needle consists of a needle cylinder and a needle head. The needle cylinder is a hollow structure with an ink-containing cavity inside, the needle head is fixed at the lower end of the needle cylinder, and part of the needle head is positioned in the ink-containing cavity. The equipment disclosed by the invention has the advantages of simple structure and high point-marking efficiency,and controlling the shape and the size of the marked point which is formed in the center of the lens is facilitated, and improving the processing quality of the follow-up lens is facilitated.

Description

technical field [0001] The invention relates to the field of glasses processing equipment, in particular to a lens processing reference point marking device. Background technique [0002] The eye is an important visual organ of the human body. Due to people's frequent incorrect reading and viewing habits and excessive eye use, myopia is becoming more and more common. As a vision correction device, the wearing rate of glasses is increasing year by year. [0003] Existing spectacles mainly include frames and lenses. The lenses are mostly disc-shaped before being processed. For lenses that match the shape and size of the frame, the existing frame is generally pre-installed with a lens template, so that the lens only needs to be processed to the size of the lens template and can meet the assembly requirements of the corresponding frame. Before the lens is cut and ground, it is necessary to determine the processing reference center, and the subsequent lens forming process needs ...
