Technical field

The utility model is related to the molds in a kind of cell phone back light source visual-alignment abutted equipment, in particular to a kind of CCD Three visual alignment mechanism of back segment machine.

Background technology

Always precision prescribed is very high for cell phone back assembling optical sources, and common product required precision is 0.03mm, usually fixed by machinery It completes position.Due to the difference of high-end backlight design, material condition is harsh, and the required accuracy 0.001mm also only has at present The fitting of CCD visions can complete the work.

And visual-alignment on the market is taken pictures the mode that camera is arranged above mold layout type generally use at present, And four cameras are set above each fitting station (mold).Since camera can be by light or shake above mold Influence so that jointing product precision is unstable.In addition, four cameras are taken pictures, contraposition, which behaves, very slowly to make entirely to set Standby operating rate declines, also can because take pictures capture coordinate points when camera it is excessive due to cause to judge coordinate points by accident.

Utility model content

The purpose of the utility model is to overcome the deficiencies of existing vision mold, provide a kind of three vision of CCD back segments machine Positioning mechanism, it has the characteristics that equipment operation is fast and stable and with high accuracy.

To achieve the above object, three visual alignment mechanism of CCD back segments machine designed by the utility model, including turntable and set It is used for the motor of driving disc rotation in the center lower end of the turntable；Turntable upper surface point centered on the center of turntable And it is symmetrically and evenly equipped with N number of mold groove along the disk edge, turntable upper surface center is equipped with vacuum shunting lid；It is described Mold groove is equipped with the M turntable form holes through the upper surface and lower face of the turntable, each on the mold groove Mold there are one being embedded；The mold includes die ontology and vacuum absorption holes, fiber-optic illuminated hole and M on die ontology The mold form hole of a hollow out；The pairing corresponding with turntable form hole of mold form hole；Have in N number of mold groove Photomoduel is equipped with below continuous N/2 mold groove, and corresponding photomoduel quantity is M-1 below single mold groove It is a；The photomoduel includes camera fixed component, area array cameras and face battle array camera lens；The shooting end face of face battle array camera lens is to institute Turntable form hole arrangement is stated, one end of the separate turntable of the face battle array camera lens is connect with the area array cameras；The area array cameras One end far from the turntable is connect with the camera fixed component；The vacuum shunting lid is distinguished by N number of vacuum shunt tube It is connected to one by one with the mold.

Preferably, the N is 8；The M is 4.

Still further, the camera fixed component is three lockable axis translation stages.It can be right by camera fixed component Area array cameras position is adjusted.

Preferably, the motor lower end is equipped with motor base；The motor base lower end is connected with main bearing sheet；The phase The one end of machine fixed component far from the turntable is connect with the main bearing sheet.

The utility model has the beneficial effects that：It is entirely set by limiting the corresponding photomoduel quantity of each mold to improve Standby work operational efficiency, the interference that reduction photomoduel is excessively brought.By the way that photomoduel to be arranged in below turntable, make Obtain the defect for being vulnerable to light or equipment shake which overcome photomoduel and causing precision unstable.

Specific implementation mode

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Three visual alignment mechanism of CCD back segments machine as shown in figures 1-4, including turntable and under the center of the turntable Motor of the end for driving disc rotation；It is put centered on the center of turntable and along the disk edge pair in the turntable upper surface Title is uniformly provided with 8 mold grooves, and turntable upper surface center is equipped with vacuum shunting lid；The mold groove is equipped with 4 Turntable form hole through the upper surface of the turntable and lower face, is embedded that there are one molds on each mold groove；Institute State the mold form that mold includes die ontology and vacuum absorption holes, fiber-optic illuminated hole and 4 hollow outs on die ontology Hole, die ontology are preferably rectangular-shape；The preferably rectangular through-hole in mold form hole；Mold form hole is regarded with the turntable Fenestra corresponds to pairing；Have in 8 mold grooves and be equipped with photomoduel below continuous 4 mold grooves, and single mold Corresponding photomoduel quantity is 3 below groove；The photomoduel includes camera fixed component, area array cameras and face battle array mirror Head；The shooting end face of face battle array camera lens arranges to turntable form hole, one end of separate the turntable of the face battle array camera lens and The area array cameras connection；The one end of the area array cameras far from the turntable is connect with the camera fixed component；It is described true Space division stream lid is connected to the mold one by one respectively by 8 vacuum shunt tubes.The camera fixed component is lockable three Axis translation stage can be adjusted area array cameras position by camera fixed component.Since the structure uses the prior art, no longer It repeats.The motor lower end is equipped with motor base；The motor base lower end is connected with main bearing sheet；The camera fixed component One end far from the turntable is connect with the main bearing sheet.Main bearing sheet only schematical sections in attached drawing.

It since photomoduel is mounted below turntable, and is fixed on main bearing sheet (weight is more than 1,000 kilograms), causes Photomoduel is not influenced by shake and light.By Experimental Comparison, three visual alignment mechanism of CCD back segments machine of the utility model Fast 2 times of the year-on-year market same category of device of efficiency, the rate of output 800 to 1000 finished product per hour.Product yield is 98 percent Left and right, year-on-year same category of device yield are higher by 4 percentage points.

Photomoduel is fixed after being debugged according to product specification, and turntable is waited for rotate above product to position of taking pictures, The area array cameras of photomoduel captures coordinate through turntable form hole and mold form hole, and output coordinate points are completed to produce by robot Product are bonded.

When work, semi-finished product backlight is fitted in mold upper end center by automatic charging, and vacuum absorption holes adsorb product Firmly, 45 degree of corners of turntable are primary, and often fitting is primary, and turntable rotation is primary, until turntable rotates 135 degree, photomoduel starts seat Mark capture simultaneously is completed to be bonded by robot.So analogize, ceaselessly operates in cycles.
