Description
Technical field
The utility model relates to a kind of thin-film solar cells laser film-engraving device, particularly uses the film device at quarter of video system assisted etch thin-film solar cells.
Background technology
In the laser film-engraving process of field of thin film solar cells, all require between the groove distance enough little, must guarantee simultaneously that groove is parallel to allow anything but, intersect.But because in carving membrane process, in different equipment, be divided into as required and carry out for several times, during also need pass through other PROCESS FOR TREATMENT, therefore the several groove all needs the mobile battery sheet, thereby be easy to cause before and after several times the location differ to, groove can't guarantee parallel; Battery sheet, check and correction groove adopt mode manually up and down simultaneously, and automaticity is low, and efficient is lower, influences the production capacity of whole production line, and the battery sheet causes a deviation easily to groove about artificial, makes product rejection, and defect rate is higher.Extensively retrieve at the problems referred to above, do not find related art scheme as yet.
The utility model content
The purpose of this utility model is to solve existing thin-film solar cells and carves in the membrane process mode manually and proofread the easy deviation of groove that groove exists, the defective that efficient is lower, and a kind of thin-film solar cells vision laser film-engraving device is provided.
To achieve these goals, the utility model has adopted following technical scheme:
A kind of thin-film solar cells vision laser film-engraving device, comprise the industrial control host that is provided with on support and the support and coupled laser, comprise that also but the machinery that the transverse and longitudinal by industrial control host control moves carves the film platform, it is characterized in that: a video frequency pick-up head is installed on described support, video frequency pick-up head links to each other with a Video Detection main frame that reads the analysis data, and Video Detection main frame and industrial control host are interconnected.
Described Video Detection main frame carries out local area network (LAN) with industrial control host use two-shipper interconnection line and is connected.
Described Video Detection main frame and industrial control host also can replace with an industrial computer that has high handling property.
Described video frequency pick-up head (band light source), its effect are the visual signals of gathering thin-film solar cells identification point coordinate, and will send industrial control host to after the signal process Video Detection host process.
Described industrial control host is responsible for accepting the signal that the Video Detection main frame sends; Be responsible for the control laser and carve the operation of film platform Control Software.
Laser---laser produces the source, and carves the film platform and cooperates and carve film.
Carve the film platform---comprise two motion leading screws of X-axis and Y-axis, move the position that cooperates vision signal can make platform make any needs in the XY plane.
Various components and parts described in the utility model comprise: industrial control host, laser, quarter, the film platform all was a prior art; Video frequency pick-up head, Video Detection main frame also all are known products.
Advantage of the present utility model is: compared with prior art be to differentiate groove by the intelligent video camera to change into data, send industrial control host to after the relative program of being installed by the Video Detection main frame is handled again, industrial control host receives after the data and by the relative program instruction and guides mobile the walking of carving the film platform, thereby accurately realize the laser scoring of thin-film solar cells fast, operation is full-automatic, simple and convenient, safe and reliable, improved production capacity and product percent of pass simultaneously greatly.

Embodiment
Embodiment:
As shown in Figure 1, a kind of thin-film solar cells vision laser film-engraving device that the utility model provides, comprise the industrial control host that is provided with on the support and coupled laser, one video frequency pick-up head is installed on described support, video frequency pick-up head links to each other with a Video Detection main frame that reads the analysis data, and Video Detection main frame and industrial control host are interconnected.Described Video Detection main frame carries out local area network (LAN) with industrial control host use two-shipper interconnection line and is connected.
Described video frequency pick-up head (band light source), its effect are the visual signals of gathering thin-film solar cells identification point coordinate, and will send industrial control host to after the signal process Video Detection host process.
Described industrial control host is responsible for accepting the signal that the Video Detection main frame sends; Be responsible for the control laser and carve the operation of film platform Control Software.
Described laser, diode excitation formula laser module for example is in order to produce laser beam.
As shown in Figure 2, but the utility model also comprises the machinery that the transverse and longitudinal by industrial control host control moves and carves the film platform, and it is made up of to platform 4 to platform 3 and X Y, and Y is provided with motor 1 and leading screw 2 to platform 3, leading screw 2 links to each other to platform with X, and X can be moved to platform 3 along Y to platform.At X a motor 5 and leading screw 6 are set on platform 4, leading screw 6 links to each other with etching workbench 7, and etching workbench 7 can be moved to platform 4 along X.
Motor 1, motor 5 all are after sending instruction by industrial control host, to carry out a certain amount of rotation, finally drive etching workbench 7 along X to and Y to moving.
Operation principle of the present utility model is as follows:
As shown in Figure 2, at first laser is squeezed on TCO transparent conducting glass 8 substrates of thin film solar cell sheet, depict article one line P1, carve simultaneously that (or two gauge points a), and video frequency pick-up head deposits in the industrial control host through the Video Detection main frame after reading these mark line data with P1 parallel marking line.After portrayal P1 finishes, TCO transparent conducting glass 8 is shifted, use plasma reinforced chemical vapour deposition method (also plasma activated chemical vapour deposition), plate amorphous silicon membrane (also polysilicon monocrystalline silicon), make it to form amorphous silicon membrane battery functi on layer, get back to afterwards on the laser-induced thermal etching device, as shown in Figure 2, the aspect that plates amorphous silicon is carried out the laser scoring P2 second time.At this moment electro-conductive glass 8 may be in heeling condition, during etching P2, video frequency pick-up head will write down automatic mobile platform according to mark line and seek mark line (perhaps gauge point), taking pictures also after finding, reading of data sends the Video Detection main frame to, use the detection software that is associated to put the coordinate data that makes new advances in order then according to the algorithm computation in the center of circle, right angle, the Video Detection main frame is sent to industrial control host with these data again, industrial control host instructs synthetic the moving of film platform at quarter by this coordinate data and corresponding instruction program, make etched second line P2 parallel, and make the two distance reach the regulation requirement with article one line P1.Carved behind the P2 mobile once more glass and carried out the magnetron sputtering film of aluminizing, the detailed process of carving P3 afterwards is identical with P2.
