Description

Lens glue injection machine
Technical Field
The invention relates to the technical field of production of spectacle lenses, in particular to a device capable of injecting glue into a lens mold.
Background
In the process of lens production, the preparation procedures of injecting glue into a lens mold, drying and shaping, and demolding are generally adopted. Referring to fig. 1, the lens mold 2 includes two mold plates 21 arranged in parallel at intervals, and an adhesive tape is wound around the outer peripheries of the two mold plates 21, and the two mold plates 21 and the adhesive tape together form a cavity having the same shape as the lens. For making things convenient for the injecting glue, the winding junction of sticky tape leaves and takes a percentage 22, and handheld taking a percentage 22 tears a section with the sticky tape when carrying out the injecting glue to expose the injecting glue mouth that the top was used for injecting glue in to the die cavity, laminate the sticky tape again after the injecting glue finishes, seal the die cavity.
Generally, the glue injection is performed manually by workers, and the defects are that the production efficiency is unstable, the glue used for producing the lenses is volatile, and the workers can have adverse effects on health in the production environment for a long time.
The ideal injecting glue process is that injecting glue with slow acceleration first, avoids the quick grow of glue injection speed to assault and produce the bubble on lens mould 2 bottom inner wall, then injects glue with great acceleration, improves the injecting glue speed rapidly, guarantees injecting glue efficiency, reduces the injecting glue speed rapidly and prevents that glue from overflowing when the injecting glue is fast accomplished at last.
The injecting glue device among the prior art, the break-make of most can only control valve, injecting glue speed is invariable, produce the bubble easily and take place the excessive glue easily, a small number of injecting glue devices that can control injecting glue speed realize through industry control system control solenoid valve aperture, the shortcoming lies in, manufacturing cost is relatively higher, simultaneously, through the above-mentioned ideal injecting glue process of industry control system control solenoid valve aperture simulation, because the stroke interval of solenoid valve is very little, be unfavorable for industry control system to realize zone control, industry control system's the control degree of difficulty is very high.
Further research by the applicant has found that the tearing and application of the tape is usually done manually by workers, which has the disadvantages of unstable production efficiency and volatility of the glue used for lens production, and that the workers may have adverse health effects in the production environment for a long time.
A few devices capable of automatically tearing the adhesive tape tear the adhesive tape in a straight-line pulling manner (for example, Chinese patent application No. CN 201810376158.7), specifically, the tap 22 is clamped by the clamping jaw, the clamping jaw moves linearly to pull the adhesive tape to tear, and the straight-line pulling has the disadvantages that the direction of the tap 22 pulled by the clamping jaw cannot adapt to the radian change of the adhesive tape, the stress direction of the adhesive tape is changed all the time in the tearing process, so that the tension of the adhesive tape is difficult to be uniformly controlled in a proper range, the adhesive tape is easy to generate irreversible deformation due to excessive pulling, the adhesive tape cannot be attached again after glue injection, and the adhesive tape is easy to generate convex bulge (unfastened) due to too small tension when being attached again.
Further the applicant also wanted to provide a mechanical mechanism that would enable the loading or unloading of the lens molds to be automated.
