Description

Lens carrier

The present invention discloses a lens carrying device, and more particularly to a lens carrying device for forming a circuit layer by using Laser Direct Structuring (LDS).

In recent years, mobile device products have been trending towards thinner, but they have also limited the space of the device. Among them, the development of electronic components is towards miniaturization and has the function of integration, which in turn conforms to the product trend. The current voice coil motor (VCM) used in the camera module of the mobile device is electrically disposed on a attached flexible printed circuit. The pedestal of the flexible printed circuit is electrically connected to the flexible printed circuit board; however, the miniaturization of the voice coil motor makes it difficult for the flexible printed circuit board to be attached to the pedestal.

The lens module and the method of assembling the same are disclosed in the Chinese Patent Publication No. I464477, which is to be attached to the flexible circuit board by using a flexible circuit board to attach the first sensor and the second sensor to the flexible circuit board. This increases the difficulty, time and cost of processing.

Therefore, in view of the lack of the above-mentioned prior art, the present creator has created a lens carrying device which forms a circuit layer directly on the pedestal by means of Laser Direct Structuring (LDS). It can effectively solve the problems of difficulty, yield, man-hour and assembly cost of attaching the flexible printed circuit board, which is relatively convenient and low-cost creation.

One of the purposes of this creation is to provide a lens carrying device that reduces the difficulty, time, and cost of manufacturing by directly forming a circuit layer on the pedestal by directly using Laser Direct Structuring (LDS).

In order to achieve the above and other objects, the present invention provides a lens carrying device including at least a base having a first through hole, a surface of the base is formed with a circuit layer, and a surface of the circuit layer a metal layer is plated; a plurality of electronic components are disposed on the circuit layer and electrically connected to the circuit layer through the metal layer; and a lens carrier is a structure having a second through hole Correspondingly disposed on the pedestal, the improvement is that the circuit layer is formed by laser direct structuring (LDS), and the lens carrier is accommodated by a lens unit of a voice coil motor (VCM) among them.

The material of the susceptor is thermosetting plastic diallyl phthalate (DAP; Diallyl Phthalate Plastics) and thermoplastic plastic polyphthalamide (PPA; Polyphthalamide), liquid crystal polymer polymerization (LCP; Liquid Crystal Polymer), Polyamide (PA; Polyamide), Polycarbonate (PC; Polycarbonate) or Polycarbonate Resin and Acrylic Butadiene-Styrene Copolymer (PC/ABS; Polycarbonate) /Acrylonitrile-Butadene-Stvrene) and the like; and the base is formed by injection molding or hot press forming.

The electronic components may be one of a Complementary Metal Oxide Semiconductor (CMOS) and a Charge Coupled Device (CCD).

Wherein, the metal layer can be formed by a chemical deposition method or an electroplating method.

The first through hole and the second through hole are circular hollow structures having the same size.

Compared with the prior art, the present invention provides a lens carrying device having the following advantages and characteristics: different from the conventional method, the voice coil motor (VCM) is electrically disposed on a base attached to the flexible printed circuit board, and A lens module electrically connected to the flexible printed circuit board. The creation of the circuit layer is directly formed on the pedestal by means of Laser Direct Structuring (LDS), which can solve the difficulty of processing the flexible printed circuit board on the pedestal and effectively improve the processing. The yield, the significant reduction in man-hours required, and the cost of assembly are relatively convenient and low-cost creations.

In order to fully understand the purpose, features and effects of this creation, the following specific examples, together with the attached drawings, provide a detailed description of the creation, as explained below:

Please refer to the first figure and the second figure, which are a three-dimensional exploded view of the creative lens carrying device and a three-dimensional assembly diagram of the creative lens carrying device. The present invention discloses a lens carrying device 1 comprising at least a base 10, a plurality of electronic components 20 and a lens carrier 30.

The pedestal 10 has a first through hole 102. The surface of the pedestal 10 is formed by a Laser Direct Structuring (LDS) method, and the surface layer of the circuit layer 104 can be chemically etched. A metal layer 106 is plated by deposition or electroplating. The material of the susceptor 10 is thermosetting plastic diallyl phthalate (DAP; Diallyl Phthalate Plastics) and thermoplastic plastic polyphthalamide (PPA; Polyphthalamide), liquid crystal polymer Polymer (LCP; Liquid Crystal Polymer), polyamine (PA; Polyamide), polycarbonate (PC; Polycarbonate) or polycarbonate resin and acrylonitrile-butadiene-styrene copolymer (PC/ABS; Polycarbonate/Acrylonitrile-Butadene-Stvrene) and the like; and the susceptor 10 can be formed by injection molding or hot press forming.

The plurality of electronic components 20 are disposed on the circuit layer 104 and electrically connected to the circuit layer 104 through the metal layer 106. The electronic components 20 can be one of a Complementary Metal Oxide Semiconductor (CMOS) and a Charge Coupled Device (CCD).

The lens carrier 30 is configured to have a second through hole 302 and is disposed on the base 10 . The first through hole 102 and the second through hole 302 are circular hollow structures having the same size.

When the lens carrier device 1 picks up the optical signal through the first through hole 102 and the second through hole 302, it converts the electrical signal into an electrical signal by the electronic component 20. Then, according to the required focal length, the lens unit 40 is appropriately driven to perform telescopic movement to perform focusing, and the adjustment of the appropriate focal length is completed.

The present invention has been disclosed in the above preferred embodiments, and it should be understood by those skilled in the art that the present invention is only intended to depict the present invention and should not be construed as limiting the scope of the present invention. It should be noted that variations and permutations equivalent to those of the embodiments are intended to be included within the scope of the present invention.
