Abstract

A manufacturing equipment, for manufacturing a molded circuit board assembly of a camera module, includes an upper mould, a lower mould, a mould fixing arrangement, and a temperature controlling arrangement, wherein the mould fixing arrangement controls opening and closing of the upper mould and the lower mound. When a substrate board is placed between the upper mould and the lower mound, a molding cavity is further formed between the upper mould and the lower mound, wherein in the molding cavity, a supporting frame forming groove is formed for forming the module support, and a light window forming element is used for forming a light window. The temperature controlling arrangement provides a molding temperature, the module supporting frame is integrally molded on the substrate board to form the molded circuit board assembly.

First claim

What is claimed is:

1. A manufacturing equipment, for manufacturing a molded circuit board assembly of a camera module, comprising:
at least one molding unit which comprises at least one upper mould and at least one lower mould,
wherein said at least one upper mould and said at least one lower mould in a closed-mould state comprise a molding cavity, said molding cavity configured to place at least one substrate board between said at least one upper mould and said at least one lower mould,
wherein said molding cavity comprises at least one supporting frame forming groove for forming a module support frame, and at least one light window forming element for forming a light window of said module support frame, wherein said module support frame is integrally molded on said at least one substrate board to form said molded circuit board assembly;
wherein said at least one upper mould comprises said at least one supporting frame forming groove and said at least one light window forming element, and said at least one lower mould comprises at least one substrate board receiving groove for placing said at least one substrate board; and
wherein said at least one upper mould further comprises at least one main flow channel groove while said at least one lower mould further comprises at least one material discharging chute, wherein said at least one main flow channel groove and said at least one material discharging chute form at least one main flow channel, wherein at least one sub flow channel is formed between said at least one upper mould and said at least one lower mould, wherein each of said at least one sub flow channels is communicated with each of said molding cavity, wherein at least one molding material entering the at least one main flow channel is guided to the molding cavity through the at least one sub flow channel, said module support frame is formed within said molding cavity, and at least one solidified molded extension is formed within said at least one main flow channel and said at least one sub flow channel.

2. The manufacturing equipment, as recited in claim 1 , wherein said at least one upper mould comprises at least one upper molding surface and said at least one lower mould comprises at least one lower molding surface for said at least one substrate board of said molded circuit board assembly being placed thereon, wherein said molding cavity is formed between said at least one upper molding surface and said at least one lower molding surface, which are in a closed-mould state.

3. The manufacturing equipment, as recited in claim 1 , wherein said at least one upper mould is adapted for said at least one substrate board of said molded circuit board assembly being placed thereat and faced downwardly, wherein said at least one lower mould further comprises at least one main flow channel groove while said at least one upper mould further comprises at least one material discharging chute, wherein said at least one main flow channel groove and said at least one material discharging chute form at least one main flow channel, wherein at least one sub flow channel is formed between said at least one upper mould and said at least one lower mould, and each of said at least one sub flow channels is communicated with each of said molding cavity, wherein at least one molding material entering the at least one main flow channel is guided to the molding cavity through the at least one sub flow channel, and said module support frame is formed within said molding cavity, and at least one solidified molded extension is formed within said at least one main flow channel and said at least one sub flow channel.

4. The manufacturing equipment, as recited in claim 1 , wherein said at least one molding unit further comprises at least one loading platform, and at least one mould fixing arrangement that is a pressing member, and said pressing member controls opening and closing of said at least one upper mould and said at least one lower mould, wherein said at least one upper mould is fixed to said pressing member and said at least one lower mould is provided on said at least one loading platform.

5. The manufacturing equipment, as recited in claim 4 , further comprising at least one material unit, at least one feeding unit and at least one transporting unit, wherein said at least one material unit supplies said at least one molding material forming said module support frame, wherein said at least one feeding unit feeds at least one substrate board array with at least one substrate board, wherein said at least one transporting unit transports said at least one substrate board array to said at least one molding unit, wherein said at least one material unit comprises at least one material transporting member that quantificationally transports said at least one molding material to said at least one molding unit.

6. The manufacturing equipment, as recited in claim 5 , wherein said at least one material unit further comprises at least one material supplying member and at least one material controlling member, wherein said at least one material supplying member stores and supplies said at least one molding material, wherein said at least one material controlling member controls an output quantity of said at least one molding material.

7. The manufacturing equipment, as recited in claim 6 , wherein said at least one material unit further comprises at least one material discharging element, wherein said at least one material discharging element has at least one plunger piston pushing said at least one molding material into said molding cavity.

8. The manufacturing equipment, as recited in claim 7 , wherein said manufacturing equipment further comprises at least one cutting unit, wherein said at least one cutting unit separates each of said at least one solidified molded extension from said module support frame.

9. The manufacturing equipment, as recited in claim 1 , wherein said at least one substrate board to be placed at said at least one upper mould and said at least one lower mould comprises a board and a plurality of circuit electronic components protruded on said board, wherein said circuit electronic components are embedded in said module support frame.
