Abstract
The utility model relates to a print positioning device for silicon chips. A screen printplate is arranged on a machine table. Five groups of unidirectional charge coupled devices (CCD) are arranged below the machine table, and distributed on the four sides of a tetragon or a chamber tetragon. Two of the five groups of unidirectional charge coupled devices (CCD) are distributed on the one side of the tetragon or the chamber tetragon, and the other three groups of unidirectional charge coupled devices (CCD) are respectively distributed on the other three sides of the tetragon or the chamber tetragon. The print positioning device is used for detecting the rotating error and the moving error of silicon chips and positioning silicon chips.
Description
Technical field
The utility model relates to a kind of silicon chip print nest.
Background technology
At present; along with expanding economy; people's living standard is more and more higher; more and more to energy demand; simultaneously environmental protection is brought bigger pressure, for addressing this problem, more and more countries is put into effect Chinese Financial Subsidy Policies; encourage to use the cleaning renewable resource, the photovoltaic industry has obtained development fast.Solar battery sheet printing navigation system adopts 4 groups of charge-coupled device (CCD)s mostly, detects the center of four edges, is difficult to detect small rotation and displacement error, causes printing precision not high.
Summary of the invention
The purpose of this utility model provides a kind of solar cell print nest.
The technical scheme that its technical problem that solves the utility model adopts is: there is half tone the workbench top, five groups of unidirectional charge coupled devices (CCD) are installed under the workbench, and be distributed on quadrangle or the tetragonal four edges of chamfering, there are two groups of unidirectional charge coupled devices (CCD) to be distributed on described quadrangle or the tetragonal limit of chamfering, three groups of charge-coupled device (CCD)s are arranged respectively on quadrangle or tetragonal three limits of chamfering, be used to detect the rotation error and the displacement error of silicon chip.
When new half tone was installed, whole workbench rose, and CCD obtains the half tone pattern position and preserves.Silicon chip is sent into workbench, and position, silicon chip limit is caught by the CCD system, concerns between calculating and the half tone position, drives the operation of the moving three-dimensional workbench of adjusting automatically, realizes location automatically.
Position fixing process: CCD1 cooperates CCD2 to detect silicon chip anglec of rotation θ, cooperates CCD3, CCD4, CCD5 detection position deviation and dimensional tolerance again, and the half tone first impression is adjusted by artificial, and it is fixing to adjust the back.Reach the precalculated position according to deviation driving movable workbench X, three variablees of Y, θ.Make half tone and silicon chip entirely on the center, reach the purpose of location.
Control system: adopt the Industry Control computer, the Windows program control system, man machine operation interface is provided with multiple printing mode, and technology personnel also can be provided with various modes and preserve automatically, freely select for different working conditions.
The closed loop control that movable workbench adopts ball screw to combine with servo-drive.Workbench is established the thimble with adsorption function.
The beneficial effects of the utility model are, because five groups of CCD of employing can prevent that the location of solar battery sheet before printing from producing rotation and mobile deviation, it is located accurately and fast.

1. charge-coupled device (CCD)s among the figure, 2. half tone, 3. silicon chip, 4. workbench.
Embodiment
By Fig. 1 to Fig. 3 as can be known, five groups of unidirectional charge coupled devices are installed on a plane under the workbench, there is half tone the workbench top, two groups of unidirectional charge coupled devices are installed on quadrangle or the tetragonal limit of chamfering, with respectively near the flex point 2mm place at two ends, three groups of charge coupled devices are distributed in its excess-three bar limit and to be optimum in midpoint, are used to detect the rotation error and the displacement error of silicon chip, in order to the Control work platform silicon chip are positioned.
When the anglec of rotation that is used for detection plane was installed new half tone, whole workbench rose, and CCD obtains the half tone pattern position and preserves.Silicon chip is sent into air-breathing workbench, and position, silicon chip limit is caught by the CCD system, concerns between calculating and the half tone position, drives the operation of the moving three-dimensional workbench of adjusting automatically, realizes location automatically.
CCD:1024 * 1280; Vision area: 7 * 5mm; Positioning accuracy :≤0.03mm
Position fixing process: CCD1 cooperates CCD2 to detect silicon chip anglec of rotation θ, cooperates CCD3, CCD4, CCD5 detection position deviation and dimensional tolerance again, and (the half tone first impression is adjusted by artificial, and it is fixing to adjust the back.Reach the precalculated position according to deviation driving movable workbench X, three variablees of Y, θ.Make half tone and silicon chip entirely on the center, reach the purpose of automatic location.
About the reciprocal running precision of CCD to location influence: the closed loop control of adopting ball screw to combine with servo-drive, repetitive positioning accuracy guarantee as long as be marked at CCD within sweep of the eye, to influence not obvious to positioning result at ± 0.015mm.Because two-way location, CCD gets half tone pattern image (being equivalent at every turn redefine positioning reference) earlier.
Adopt the Industry Control computer, the Windows program control system, man machine operation interface is provided with multiple printing mode, and technology personnel also can be provided with various modes and preserve automatically, freely select for different working conditions.
The workbench alignment system:
A. workbench aligning structure: CCD absorbs the silicon chip image automatically, linear motor driving workbench alignment system.
B. adsorb with blow attached: automatically fixedly silicon chip printing of absorption, chromatography is accurate.Automatically blow attached, the convenient silicon chip that manually picks and places.
C. worktable lifting structure: the worktable lifting height is a servo-drive, the adjustable height precision, and numeral is set.
D. bench top needle construction: the silicon chip loading and unloading are adopted and are refuted the fork thimble structure, the thimble design and installation on workbench, whole equal tool adsorption functions of thimble.
