Description

RELEASE PROPERTIES TYPE NON-DICING MOLD FOR MANUFACTURING MICROARRAY LENSES AND MANUFACTURING METHOD OF MICROARRAY LENS USING THIS

The present invention relates to a mold release type non-dicing mold for manufacturing a microarray lens and a method for manufacturing a microarray lens using the same.

More specifically, in a state in which the object to be molded is inserted between the lower core part and the upper core part, the press plate part presses the upper core part to mold the object to be molded so that the production of the microlens is automated, so that the manpower required for manufacturing the microlens It relates to a releasable type non-dicing mold for manufacturing a microarray lens configured to save money, and a method for manufacturing a microarray lens using the same.

In general, aspheric lenses can be processed into hard and brittle materials such as cemented carbide due to the development of ultra-precision processing, and aspherical lenses with small shape errors can be produced in a short time.

As a conventional method of molding an aspherical lens, the glass exhibits a property of softening as it exceeds the transition temperature (Tg). It is called Glass Mold Press (GMP).

Since glass exhibits a significant change in physical properties above the transition temperature (Tg), the difference in physical properties according to heating and cooling rates is different, so the molding apparatus performs multiple heating processes, pressing processes and multiple cooling processes in a single chamber.

However, the conventional GMP method has a limit in that it is not possible to reduce the time required for product production to a specific time or less in order to prevent process stress of the glass material.

Such a conventional GMP method applies a high-pressure press at the glass transition temperature state, so it gives a lot of stress to the glass material, so that the degree of physical property deformation of the glass material is increased even when cooling is performed gradually.

In addition, since the conventional GMP method applies a high-pressure press in a short time, the core may be greatly impacted and damaged. That is, the lifespan of the core may be reduced due to frequent thermal changes and high pressure pressing.

As such, as a lens molding apparatus using the GMP method, domestic registration publication No. 1739760 discloses an automated apparatus for manufacturing an aspherical lens that can automate the manufacturing process of an aspherical lens with a mold in which a plurality of cavities are formed.

The above-described prior art performs a press operation for molding a lens through a pressing means in a mold put into a pressure molding machine. Accordingly, there is still a problem that the mold may be damaged because a high-pressure press is applied to the mold in a short time. That is, the mold is damaged by frequent thermal changes and high-pressure press, which may shorten the life of the mold.

On the other hand, small mobile devices are equipped with various additional functions in addition to a simple voice call function to enhance user convenience. With the recent rapid development of information and communication technology, improvement of data communication speed and expansion of data communication volume are realized, and high-pixel camera modules with micro lenses applied to CCD image sensors or CMOS image sensors are used in mobile devices such as mobile phones and notebook computers. is being built in

Micro lenses are widely used in liquid crystal displays and optical communication systems, as well as medical devices.

As such a high-pixel image sensor is applied, high-resolution photos and videos can be taken. However, due to the miniaturization of mobile devices, the camera module needs to be manufactured to be thinner and lighter.

As a manufacturing method for lightening the camera module, a method of manufacturing a lens used for a camera module in the same shape in large quantities using a polymer that is cured by UV light is applied.

The lens manufacturing process of the polymer replication method as described above is first produced by a mastering process of manufacturing a master lens, a stamping process of manufacturing a lens manufacturing mold using the master lens manufactured by the mastering process, and the stamping fixation It consists of an embossing process of manufacturing a lens wafer by injecting a liquid polymer into the mold, and a dicing process of cutting the lens wafer.

Among the above lens manufacturing processes, the mastering process involves first dropping a liquid polymer on the core and then exposing it to UV light to cure the polymer first, then drop the liquid polymer again on the cured lens part secondarily, and apply it to the glass wafer. Attach the lens unit. By repeatedly performing the above process, a plurality of master lenses are formed on one glass wafer, and then the master lenses are cured by exposing the glass wafer to ultraviolet rays.

However, in the conventional mold for manufacturing a master lens, since the rough surface of the metallic material and the polymer are in direct contact, a part of the polymer is attached to the surface when the mold is separated, resulting in defects.

On the other hand, in order to produce a large amount of lenses, a plurality of aspherical convex portions are formed on a base substrate, diced to separate them into a single object, and then post-processing is performed.

As shown in (a) of FIG. 2, this aspherical square lens uses a cutter (C) to form a square shape after forming a number of aspherical surfaces on the base substrate (P). It requires post-processing and a cleaning process to remove foreign substances. Accordingly, product yield is reduced due to quality degradation after the dicing process, and tolerance management between core molds and quality difference between cores occur.

In this way, when relying on machining for microlens processing, there are many difficulties. New processing techniques have been tried to overcome this problem, but there is a limit to reducing the dimensional deviation between products, and the manufactured lens is also expensive.

On the other hand, the manufacturing apparatus using a slide mold is installed on the upper part of the plate, a core pin for lower molding of the lens is coupled to the center, and a lower core having a plurality of guide grooves formed thereon, and is seated in the guide groove to reciprocate while It is installed on the upper part of the slide core forming the side of the lens and the lower core, and a core pin for forming the upper lens is coupled to the center, and an upper core that slides and moves the slide core when descending, and it is installed on the upper part of the support plate. It includes a fixing holder having a core hole formed therein to accommodate the lower core and the upper core, and a sleeve having a through hole having an inner diameter equal to the outer diameter of the fixing holder to be inserted outside the fixing holder.

Figure 2 (b) shows the main part of the manufacturing apparatus using the slide mold as above. This slide mold lowers the upper core in the vertical direction and at the same time slides in the horizontal direction to form a rectangular substrate including the lens by the slider (S). There is an impossible problem.
