Technical Field

[0001] The invention relates to the field of lens manufacturing, and in particular to a lens manufacturing and curing device. Background Art

[0002] Lenses are transparent materials with one or more curved surfaces made of optical materials such as glass or resin. After polishing, they are often assembled with eyeglass frames to form glasses, which are used to correct the user's vision and obtain a clear field of vision. Currently, lenses are usually made of resin or plastic, which is more durable than glass.

[0003] In the prior art, lenses are usually made by injecting raw materials into a mold and then fixing the raw materials by thermal curing. There are multiple steps from the injection of raw materials to the thermal curing process, all of which require manual participation. Although manual participation can improve the quality of the lens through observation, the processing efficiency is low, which affects the product quality. Summary of the invention

[0004] In order to solve the problem that in the prior art, multiple steps from the injection of raw materials to the thermal curing process in the lens manufacturing process require manual participation.

[0006] By adopting the above technical scheme, the lens production and curing process can be completed efficiently. The setting of the conveying mechanism enables the mold to be stably transferred between the various workstations, thereby improving production efficiency. The injection hood in the injection mechanism is embedded in the mold to ensure the accuracy of the injection process and avoid spillage of raw materials. It can be completed automatically. When bubbles are observed, the blocking block can be retracted to connect the reflux groove with the reflux hole. Due to the instantaneous change in air pressure, the bubbles can be discharged. The discharge of bubbles may also be accompanied by the reflux of part of the raw materials. The refluxed raw materials can be collected in the reflux tank, effectively improving the quality and efficiency of lens production.

[0007] Optionally, an ultrasonic flaw detector is provided on the injection head, and the ultrasonic flaw detector is used to detect bubbles in the mold. When the ultrasonic flaw detector detects bubbles, the blocking block is retracted into the blocking groove.

[0008] By adopting the above technical solution, the ultrasonic flaw detector can detect bubbles in the mold, promptly detect the mold that produces bubbles during injection, and automatically control the movement of the blocking block, thereby effectively avoiding the influence of bubbles on the quality of the lens and improving the product qualification rate.

[0011] Optionally, a heating tube is further provided at a position corresponding to the reflux groove in the injection hood, and the heating tube is used to heat the reflux groove.

[0012] By adopting the above technical solution, the setting of the heating tube can heat the raw materials in the reflux tank, prevent the raw materials from solidifying or deteriorating in fluidity due to temperature reduction during the reflux process, and reduce the blockage of the reflux tank, thereby ensuring that the raw materials can smoothly reflux into the reflux tank.

In addition, the cooperation between the rubber strip and the compression airbag can also improve the stability of mold fixation and ensure the smooth progress of the injection process.

[0017] Optionally, the pasting mechanism includes a pasting rack, on which a tape wheel is rotatably provided, and the tape wheel is used to install the tape. A separation rack is also provided next to the tape wheel, and the separation rack is also rotatably connected to the pasting rack.

[0018] By adopting the above technical solution, the tape wheel can be glued out by the bonding rod and pulled to fit the tape to the mold so as to be closed when the mold is completed by injection molding, and the cutting rod can cut the glued tape. Then the separation frame continues to rotate so that the bonding rod can continue to bond with the tape and paste the tape to the next mold.

[0019] Optionally, a spring is arranged between the bonding rod and the separation frame, one end of the spring is fixedly connected to the bonding rod, and the other end of the spring is fixedly connected to the separation frame, and the spring has a tendency to push the bonding rod to move toward the tape wheel, and a spring is arranged between the cutting rod and the separation frame, one end of the spring is fixedly connected to the cutting rod, and the other end of the spring is fixedly connected to the separation frame, and the spring has a tendency to push the cutting rod to move toward the tape wheel.

[0020] By adopting the above technical solution, the bonding rod has a tendency to move toward the tape wheel under the action of the spring, thereby ensuring that the tape can be firmly bonded, and the cutting rod can cut the tape more effectively, and after cutting, it can also scrape and press the tape, so that the tape fits more closely on the mold.

[0021] Optionally, a bonding wheel is rotatably provided on one end of the bonding rod away from the separation frame, and the bonding wheel can abut against the tape on the tape wheel.

[0022] By adopting the above technical solution, the rotating setting of the bonding wheel can reduce the friction between the adhesive tape, making the separation process of the adhesive tape from the bonding wheel smoother after being attached to the mold, and reducing the situation where the tape cannot be separated due to excessive friction.

[0023] Optionally, it also includes a stirring mechanism, which is used to store raw materials. A material passing pipe is arranged between the stirring mechanism and the injection mechanism, and the material passing pipe is used to pass the raw materials in the stirring mechanism into the mold.

The conveying mechanism is used for transportation throughout the entire processing process, which can further improve the degree of automation and further improve production efficiency.

[0025] In summary, this application has at least the following beneficial effects: The present application solves the problem that in the prior art, multiple steps in the lens manufacturing process from the injection of raw materials to the thermal curing process require manual participation. Although manual participation can improve the quality of lenses through observation, the processing efficiency is low, which affects the product quality. The present application sets up automated equipment and uses machinery instead of manpower for processing, thereby improving the processing efficiency and product quality.

[0026] The present application also provides a component capable of detecting and eliminating bubbles, thereby reducing the occurrence of bubbles in the product production process that affect the quality of the lens and further improving product quality. BRIEF DESCRIPTION OF THE DRAWINGS
