Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings.

[0027] like figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 The glue injection device of the shown resin lens pouring machine includes a frame 101 and a mold clamping part arranged on the frame 101. The mold clamping part includes a main shaft 102 and a motor that drives the main shaft 102 to rotate. On the main shaft 102 Set the fixed plate 103, set the gasket on the fixed plate 103, set the suction hole in the center of the fixed plate 103, the suction hole is connected with the air pump through the conduit 106, like this, after the lens mold is placed on the gasket, it will be sucked by the air pump Air, the lens mold can be sucked on the gasket in front of the fixed plate 103, so that the colloid injection mechanism 202 can inject glue to the lens mold. Fixtures 104 are set on both sides of the fixed disk 103, and the fixtures 104 are driven by a cente...

Abstract

The invention discloses a glue injection device of a resin lens casting machine, and belongs to the technical field of lens manufacturing. The glue injection device comprises a rack (101) and a mode locking component, and both sides of a fixed disk (103) are provided with a fixture (104) and a parallel clamping cylinder (105); and the rack (101) is provided with a bracket I (201) which is provided with a glue injection mechanism (202), a puncture mechanism (203) and an induction mechanism I (204). The glue injection device disclosed by the invention is beneficial to injecting glue through an injection needle (2021), and the glue is prevented from overflowing from an injection needle (2021); bubbles are avoided in a mould, and the casting quality of a resin lens can be improved; and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of lens manufacturing, and relates to a glue injection device, in particular to a glue injection device for a resin lens pouring machine. Background technique [0002] During the manufacturing process of resin lenses, monomer preparation, mold casting, polymerization and curing are required. During the casting process, the liquid monomer needs to be injected into the assembled mold, and the monomer is filled with the mold. No overflow and no bubbles, if the monomer is not filled, or there are bubbles, or overflow, it will directly affect the quality of the spectacle lens, and even cause the spectacle lens to become a substandard product. [0003] In the prior art, the applicant disclosed a fully automatic resin lens pouring machine in a Chinese invention patent with an application date of September 2, 2014 and an application number of 201410442087.8. The casting part includes a positioning cylinder. The len...
