Description

A kind of mobile phone camera module group assembling method
Technical field
The present invention relates to cell-phone camera fuse head production method, be specifically related to a kind of mobile phone camera module group assembling method.
Background technology
Known, what mobile phone realized camera function dependence is its internal photographic head module of installing.Shooting head mould Group refer to optical lens and image sensor (CCD or CMOS) combine and formed a kind of small-sized Optical digital image converts module.Mobile phone camera module is mainly by lens assembly, image sensor and line Road plate composition, its packaging technology often comprises the following steps: carry out the image sensor being welded on wiring board Cleaning;Utilize automatically dropping glue equipment on-line road plate correspondence position point glue;Lens assembly and wiring board are passed through glue Body bonding assembles;To assembly precompressed, then toast.
In tradition packaging technology, image sensor is cleaned employing manually, seriously reduce life Produce efficiency.It addition, gluing process separates operation with packaging technology, wherein assemble the assembling manually used, Reduce further production efficiency.Furthermore, before assembly toasts, needing will first with specific tool Group shape body is fixed, presses, and puts baking box the most again into and toasts so that roasting, pressure can not be carried out simultaneously, Further reduce production efficiency.More it is essential that this utilize tool pressure, recycling oven cooking cycle Mode serious because assembly surface covers tool reduce the heat conduction efficiency that baking box is actual;And, The use of tool too increases production cost.
For the problems referred to above, those skilled in the art have trial directly to be placed by assembly and have pressing function Baking box, a step completes to press roasting operation, but effect is the most undesirable.Reason is, due to the size of lens assembly There are differences, the pressure disc directly using baking box smooth carries out pressing, certainly will cause the assembly that thickness is low not Compacted, toasted rear colloid is because of expanded by heating so that lens assembly reduces with the adhesion of wiring board.
Summary of the invention
It is an object of the invention to overcome weak point of the prior art, it is provided that a kind of mobile phone camera module group Dress method, to solve, production efficiency is low, cost is high and assembles inferior technical problem.
It is an object of the invention to be achieved through the following technical solutions:
A kind of mobile phone camera module group assembling method, this technique comprises the steps:
Step 1, cleaning, utilize automatic cleaning equipment that the wiring board being welded with image sensor is cleaned;
Step 2, some glue and assembling, utilize some glue being assembled into one equipment to be automatically performed at wiring board correspondence position Put glue, wiring board for dispensing glue is bondd by colloid with lens assembly;
Described glue being assembled into one equipment includes pedestal, is erected at pedestal two ends and extends to above pedestal Bracing frame and be arranged on the lifting shaft at bracing frame top, described pedestal sets up plummer, described lifting shaft Bottom be provided with point glue equipment, suction means and be whether that the optics scrapping plate passes in order to detect wiring board Induction device;
It is provided with wiring board fixed area, lens assembly fixed area and lens assembly angle on described plummer to rectify Positive district, wherein lens assembly fixed area is made up of forward camera lens fixed area and reverse camera lens fixed area;
Step 3, pressure is roasting, and assembly step 2 completed is placed on pressure baking box and carries out pressing roasting operation, described pressure Baking box includes heating platen and the heating board of lower section of top, and the bottom surface of described heating platen is equipped with layer of silica gel, Being lain in by assembly on heating board, assembly is compressed by heating platen downward to through layer of silica gel.
In above-mentioned steps 2, described glue and assembling specifically include following steps:
Complete the wiring board that step 1 cleaning processes to be transported to wiring board fixed area and fix, the mirror that forward is placed Head assembly is transported to forward camera lens fixed area and fixes, and oppositely positioned lens assembly is transported to reverse camera lens Fixed area is fixed;
The optical sensing devices being arranged on lifting shaft can move to wiring board fixed area to the many height on wiring board Unit detects one by one, and according to prestored information judge wiring board subelement whether as scrapping plate, if just Often plate, then carry out drawing glue, if scrapping plate, point glue equipment at this subelement correspondence position by point glue equipment Do not carry out drawing glue operation;
Suction means on lifting shaft picks up as required and is positioned at forward camera lens fixed area or reverse camera lens fixed area Lens assembly, removed and be fixed to lens assembly angle correction district;
Lens assembly angle correction district completes the angle adjustment to lens assembly according to parameter preset so that it is with line Road plate matches;
Lens assembly after suction means will adjust angle is removed to wiring board fixed area, lens assembly correspondence is put Put the upper surface at normal-sub unit, complete assembling operation.
As improving technical scheme, described suction means controls, to realize moving up and down, to work as suction by a cylinder Fetching is put when carrying out sucking action, and cylinder controls it and extends downwardly from;When point glue equipment works, cylinder controls Suction means is upwards retracted, it is to avoid it extends downwardly from long and stops point glue equipment to work.
Concrete, described optical sensing devices is range sensor or CCD scanning means, range sensor Highly carry out the differentiation scrapping between plate and normal panel less than normal panel according to scrapping plate for want of chip; CCD scanning means then makes a distinction according to normal panel and the image difference scrapped between plate.
The present invention has the following advantages and beneficial effect compared to existing technology:
(1) gluing process is integrated with packaging technology, improve production efficiency.
(2) assembly is separated with special fixture, and assembly is directly placed pressure baking box and carries out precompressed simultaneously With baking flow process, both improve production efficiency, and saved again tool cost, and improve being heated of assembly Efficiency;It addition, by arranging layer of silica gel in pressure baking box, utilize tension force that layer of silica gel has, pliability, Insulation, environmental protection characteristic, compensate the difference in height of assembly, improves hot pressing quality, it is ensured that assembling quality;Again Person, the mode that the present invention uses pressure roasting is the heating platen pressure on baking box top, the heating board heating of bottom, and Heating plate directly contacts with assembly, improves heat conduction efficiency.
(3) gluing process of the present invention completes on a plummer with packaging technology, further increases life Produce efficiency;And the mobile phone camera module group assembling method provided based on this plummer present invention both can effectively pick Cost-effective except the wiring board scrapped, also can meet rotate to an angle wiring board and negative and positive typesetting circuit The processing of plate needs, applied widely.
(4) present invention is upwards retracted by cylinder control suction means, it is to avoid it extends downwardly from long and stops Point glue equipment works.
