Accompanying drawing 3 is the fixing means process flow diagram of the lens combination according to the present invention; And
Accompanying drawing 4 is for showing the made contact image sensor module of fixing means of the lens combination according to the present invention.
[embodiment]
Please consult accompanying drawing 3 and accompanying drawing 4 simultaneously, wherein accompanying drawing 3 is the fixing means process flow diagram of the lens combination according to the present invention, and it is applicable to contact image sensor module 4 as shown in Figure 4.This fixing means comprises the following steps:
Among the step S300, provide a pedestal 10 and a lens combination 12, wherein this lens combination 12 is made in the mode of plastics ejection formation.
But shell is made for the material of ultrasonic fusion outside this lens combination 12, but the material of ultrasonic fusion is acrylonitrile-butadiene-styrene copolymer compound (Acrylonitrile-Butadene-Styrene for example, ABS), acetal resin (ACETAL), acryl (Acrylic Resin, PMMA), poly-inferior phenoxide (NORYL), nylon (NYLON), polycarbonate (Polycarbonate, PC), tygon (Polyethylene, PE), polypropylene (Polypropylene, PP), polystyrene (PS), poly-Feng (POLYSULFONE), Polyvinylchloride (Polyvinyl Chloride, PVC), styrene-acrylonitrile copolymer eyeball (SAN), it is made that polyester acid fat (POLYSTER) and polyacrylonitrile-Ao Long (XT-POLYMER) constitute in the group at least one.
But this pedestal 10 is made for the material of ultrasonic fusion, acrylonitrile-butadiene-styrene copolymer compound (Acrylonitrile-Butadene-Styrene for example, ABS), acetal resin (ACETAL), acryl (Acrylic Resin, PMMA), poly-inferior phenoxide (NOORYL), nylon (NYLON), polycarbonate (Polycarbonate, PC), tygon (Polyethylene, PE), polypropylene (Polypropylene, PP), polystyrene (PS), poly-Feng (POLYSULFONE), Polyvinylchloride (Polyvinyl Chloride, PVC), styrene-acrylonitrile copolymer eyeball (SAN), it is made that polyester acid fat (POLYSTER) and polyacrylonitrile-Ao Long (XT-POLYMER) constitute in the group at least one.
Among the step S310, offer a groove 40 in this pedestal 10.Because the purpose of this groove 40 is ccontaining this lens combination 12, so the size of this groove 40 needs the size more than or equal to this lens combination 12 at least.
Among the step S320, this lens combination 12 is positioned in this groove 40.
Among the step S330, fuse at least one junction 42 of this lens combination 12 and this groove 40 with ultrasonic, so that this lens combination 12 is fixed in this groove 40.That is to say, high-frequency friction is implemented in junction 42 to this lens combination 12 and this groove 40, make molecule produce heat rapidly, when heat enough melts the junction of this lens combination 12 and this groove 40, stopping supersonic shakes, the fixing of this lens combination 12 and this pedestal 10 finished in the junction meeting fusion and the curing of this lens combination 12 and this groove 40 by this.
In the step of step S330 ultrasonic fusion, at first need preestablish a fusion time and a fusion scope.In one preferred embodiment, the ultrasonic fusion time was between 0.1 to 3 second, and ultrasonic fuses scope at least greater than 0.2 square millimeter, and should the fusion scope need contain this lens combination 12 and this pedestal 10 simultaneously.Then according to this predefined fusion time and this at least one junction 42 of should the fusion scope fusing this lens combination 12 and this groove 40, wherein the operating frequency that fuses of ultrasonic is between 10000 to 40000 hertz.
With accompanying drawing 4 is example, implements the ultrasonic fusion in this lens combination 12 and six junctions 42 of this pedestal 10, and these six junctions 42 are symmetrically located at this lens combination, and about in the of 12 both sides.In other embodiment, the junction 42 of implementing the ultrasonic fusion there is no restricted number, and its position also can be asymmetric mode, for example in two junctions of lens combination 12 upsides and junction of downside implement the ultrasonic fusion.
The fixing means of the present invention's lens combination 12 is compared with known techniques, has following advantage: (1) uses the mode of ultrasonic fusion to fix this lens combination 12, does not have the problem of using the viscose crawling and polluting lens combination 12.(2) use the mode of ultrasonic fusion to fix this lens combination 12, the situation of rocking easily when not having with trip fixedly takes place.(3) use the mode fixed lens group 12 of ultrasonic fusion can not produce waste material, the more convenient and environmental protection of subsequent treatment.(4) use mode fixed lens group 12 processing of ultrasonic fusion quick, can shorten the manufacturing time-histories of contact image sensor module 4.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
