Problems solved by technology

However, there are still many issues or processes to be solved or improved in the application of WLCM
For example, the lenses used in WLCM are generally obtained by plastic injection molding, which are easy to deform or change in optical properties under high temperature, thus affecting the imaging quality of WLCM
Therefore, the current WLCM cannot pass the reflow process (reflow, temperature above 260°C) in the SMT process.
In addition, the production efficiency and production cost of lenses also affect the application of WLCM

Abstract

The invention provides lens manufacturing equipment. The equipment comprises a base with an upper surface, a plurality of bottom preforms arranged on the upper surface, a pressing plate which is arranged above the base and provided with a lower surface opposite to the upper surface, a plurality of upper preforms arranged on the lower surface, an ultraviolet light source and a first driving device, wherein each bottom preform comprises an upper parting surface which is back to the base and provided with a mold cavity; the mold cavity is used for accommodating an ultraviolet curing adhesive; each upper preform is aligned with the corresponding bottom preform and comprises a lower parting surface which is back to the pressing plate and provided with a forming surface opposite to the mold cavity; the ultraviolet light source is used for curing the ultraviolet curing adhesive; and the first driving device is used for driving the pressing plate to move to the base in the process of curing the ultraviolet curing adhesive, so that the ultraviolet curing adhesive is subjected to mold pressing by using the mold cavity and the forming surface until the ultraviolet curing adhesive is completely cured to form a plurality of lenses.

Description

technical field [0001] The invention relates to a lens manufacturing equipment. Background technique [0002] Wafer level camera module (wafer level camera module, WLCM) is conducive to the miniaturization of electronic products using WLCM due to its small size, and is compatible with surface mount technology (surface mount technology, SMT), which is conducive to improving the adoption The assembly efficiency of electronic products of WLCM has thus received widespread attention. However, there are still many issues or processes to be solved or improved in the current application of WLCM. For example, the lens used in WLCM is generally obtained by plastic injection molding, which is easy to deform or change in optical properties under high temperature, thus affecting the imaging quality of WLCM. Therefore, the current WLCM cannot pass the reflow process (reflow, temperature above 260° C.) in the SMT process. In addition, the production efficiency and production cost of len...
