Description
Technical field
The invention belongs to machining eyeglass field, be specifically related to a kind of resin lens automatic demoulding equipment and method.
Background technology
In traditional resin lens processing, be all flow in mold for frames by the resin material of liquid state, then get up by adhesive tape envelope, be cured shaping, the material contacted with resin material in usual grinding tool is glass.After curing molding, tear adhesive tape, be all by being manually separated with grinding tool by eyeglass, due in solidification process, eyeglass and grinding tool have bonding, very difficult separation, especially the edge of grinding tool and lens contacts, usually needs slowly to prize could be separated with cutter head, now can be easy to make eyeglass in separation process by edge damage, such to affect eyeglass attractive in appearance, and the efficiency be separated is also very low.
Summary of the invention
In order to solve the problem, the invention provides a kind of resin lens automatic demoulding equipment and method, concrete technical scheme is as follows:
A kind of resin lens automatic demoulding equipment, comprises drive, the conveyer belt be arranged on described drive, the motor that is connected with drive, through the thermal treatment zone and cooling zone in described conveyer belt process.
When the mold for frames of curing molding is taken out from curing oven, be cooled to 45 ~ 55 DEG C, then adhesive tape is removed by hand, now lens edge and grinding tool stick together, now, place on a moving belt, rotated by driven by motor drive, grinding tool is delivered to the thermal treatment zone, be heated to 75 ~ 85 DEG C, now because eyeglass is resin material, can soften, now, deliver to cooling zone again, rapid cooling, eyeglass cools fast, now be not able to do in time to bond again with grinding tool, now, grinding tool is separated automatically with eyeglass, such eyeglass can not edge damage, and realize automation, can the mass demoulding, production efficiency is improved.
Preferred improvement is: described motor is stepper motor.
Owing to being consistent around heat time, therefore motor can be arranged to stepper motor, automatically carry out transmission every certain hour, automation can be realized like this, the mold for frames tearing adhesive tape off is placed on a moving belt by artificial only needs, convenient and swift, saves labour turnover.
Preferred improvement is: the described thermal treatment zone externally connects air blast.
Preferred improvement is: described cooling zone externally connects air blast.
By wind-force, the air agitation in the thermal treatment zone or cooling zone is got up, realize inner air uniform stirring, make internal temperature homogeneous, ensure heating or cooling effect.
Preferred improvement is: the described thermal treatment zone is connected with same air blast with cooling zone, and described air blast connects air channel, and described air channel is connected to the described thermal treatment zone and cooling zone respectively by tube connector.
In continuous firing, the thermal treatment zone and cooling zone are in working stage simultaneously, share an air blast, save equipment cost.
Preferred improvement is: the tube connector air outlet place that described air channel is connected with the thermal treatment zone or cooling zone is connected a wealthy wind device.
Owing to being provided wind to accelerate the air flow effect of the thermal treatment zone and cooling zone by air blast, after being connected by tube connector, air-flow is narrow, increases this wealthy wind device, is namely similar to upside down funnel type device, by air dispersion, strengthens airflow convection effect.
Preferred improvement is: the tube connector inside that described air channel is connected with the thermal treatment zone is provided with heating element heater.
Preferred improvement is: the tube connector outside that described air channel is connected with cooling zone is provided with cooling body.
The air-flow produced due to air blast is outdoor airflow temperature, when entering the thermal treatment zone or cooling zone, need additional absorbent or release heat, the heating effect of the thermal treatment zone, the cooling effect of cooling zone can be reduced like this, now heating arrangements or cooling body are set at tube connector place, heat or cool to like this air-flow of coming from air blast in advance, it is less to make to enter air-flow difference in the thermal treatment zone or cooling zone, can not affect heat transfer effect.
A method for resin lens automatic demoulding, specifically comprises the following steps:
Step one: taken out by the mold for frames of curing molding, wherein the eyeglass of curing molding has gummed with grinding tool especially grinding tool surrounding, and be cooled to 45 ~ 55 DEG C, now, workman can contact, and conveniently tears adhesive tape off.
Step 2: the mold for frames tearing adhesive tape in step one off is heated to 75 ~ 85 DEG C, at such a temperature, progressively soften the eyeglass shaping by resin solidification, the place of gluing together with grinding tool also starts progressively to lose glue performance, continues 3 ~ 5min;
Step 3: mold for frames under high temperature in step 2 is placed into cooling zone rapidly, is quickly cooled to 20 ~ 30 DEG C, and control cool time at 25 ~ 40 seconds, the material that lens surface plays adhesive effect directly loses viscosity, and now eyeglass is separated automatically with mold for frames.
Beneficial effect of the present invention: a kind of resin lens automatic demoulding equipment provided by the invention, can greatly accelerate in resin lens process, the separative efficiency of eyeglass and grinding tool, and round Realization automation processing, avoid causing artificial waste, reduce production cost.
