The general quantity of this kind of cell piece is more and be not easy by people as choosing, although existing tubular type PECVD is generally equipped with automatic mechanical hand to be substantially unattended, but few sheet hidden problem such as to split in supply and stove not in time to be there is in graphite boat, cause the part normal battery sheet back side to suffer nitride deposition the most at last.Occur for reducing this phenomenon, someone did improvement, and such as application number is the Chinese patent of 201320643883.9: a kind of graphite boat, discloses a kind of graphite boat, comprises graphite flake, ceramic bar and graphite bars, ceramic bar and graphite bars internal package reinforcement; Reinforcement is metal material; The material of reinforcement is iron.Adopt the mode adding reinforcement in the middle of ceramic bar and graphite bars, enhance the intensity of graphite bars and ceramic bar, reduce the rate that fractures of ceramic bar and graphite bars, effectively prevent silicon chip fall sheet and frequently change graphite bars, ceramic bar, substantially increase operating efficiency, save cost simultaneously, fallen sheet although can reduce, to falling still just cannot choosing of sheet.And at present in industry common practice be all remove this kind of cell piece of picking artificially, existing method be simple people for removing picking, taking up battery piece device at present due to us is 100 flower basket types, artificially cannot see abnormal cell piece intuitively by naked eyes; Equally, if the cell piece of reverse side plated film can not be found to flow into serigraphy end in time and cover abnormal will temporarily hiding through back surface field printing aluminium paste, until the abnormal downshift of test electrical property enters poor efficiency shelves, and this kind of cell piece owing to very easily causing back surface field obscission through nitride deposition in the back side after oversintering.And also there is normal cell piece during artificial picking and suffer the heaviest waste product that becomes of artificial pollution, not only wasted manpower in this approach but also easily caused the secondary pollution of cell piece.Therefore, this kind of cell piece does not also have the method for special efficacy that it is chosen in time.
Utility model content
The purpose of this utility model is to provide a kind of automatic picking device for abnormal solar battery sheet rational in infrastructure, simple to operate, can preparing to pick out two-sided nitride deposition cell piece efficiently.
In order to reach the purpose of this utility model, technical scheme is as follows:
For an automatic picking device for abnormal solar battery sheet, the programmable logic controller (PLC) comprising color mark sensor, the light coupling relay be electrically connected with described color mark sensor and be electrically connected with described light coupling relay.
As preferred technical scheme: also comprise the picking device, warning device and the brake apparatus that are electrically connected with described programmable logic controller (PLC).
Color mark sensor refers to and detects various label, even if background color has the color of fine distinction also can detect, processing speed is fast.Automatic adaptation wavelength, can detect the small differences of gray value, has nothing to do with the blend color of label and background.
Color mark sensor is usually used in detecting the spot on specific colour code or object, and it is by realizing color spot graph compared with non-color scale space, instead of directly measures color.Color mark sensor is actual is a kind of reversing device, light source is installed perpendicular to target object, and receiver and object acutangulate direction and install, and allows its only detect scattered light from target object, thus avoid sensor directly to receive reverberation, and it is very narrow that light beam can be made to focus on.Incandescent lamp and monochromatic source all can be used for color spot graph.
Photo-coupler (opticalcoupler, english abbreviation is OC), also known as photoisolator or photoelectrical coupler, is called for short optocoupler.It take light as the device that medium carrys out transmission of electric signals, usually photophore (infrared light-emitting diode LED) and light-receiving device (photosensitive semiconductor pipe) is encapsulated in same shell.When input power up signal, photophore emits beam, and light-receiving device just produces photoelectric current after accepting light, flows out from output, thus achieves " electrical-optical-electricity " conversion.Be that medium is coupled to the photoelectrical coupler of output input end signal with light.
Light coupling relay is the one of solid-state relay, and general relay is all mechanical contact, flows through coil become magnetic magnet attraction contact by energising, thus controls state of opening the light, and light coupling relay operation principle is similar to optocoupler.Because detection signal exists pressure drop phenomena after exporting low and high level access load, load cannot be driven, so light coupling relay must be equipped with carry out the stability that signal isolation carrys out control DC24V (24 volts, direct current).
Programmable logic controller (PLC) (Programmable Logic Controller, PLC), it adopts a class programmable memory, for its internally stored program, actuating logic computing, sequential control, regularly, counting and the user oriented instruction such as arithmetical operation, and by numeral or analog pattern input/output various types of machinery of control or production process.The signal that color mark sensor spreads out of can be accepted, and carry out analyzing and processing, send instruction to warning device, brake apparatus and picking device.Picking device is a structure being similar to manipulator, abnormal cell piece can be picked up and take away.
During real work, automatic picking device for abnormal solar battery sheet is arranged on the serigraphy material loading end of solar battery sheet, namely before printing, each solar battery sheet will pass through this automatic picking device in transport process: color mark sensor is by contrasting color label, automatic adaptation wavelength can detect that difference that gray value is less is to detect the difference of cell piece color, and then identify abnormal cell piece, then send a signal to light coupling relay.Light coupling relay continues to send a signal to PLC, and PLC makes instruction to after signal transacting, and when color mark sensor detects that cell piece color is normal, then cell piece continues uninterrupted transmission; When color mark sensor detects cell piece color exception, warning device on PLC sends warning at once, this abnormal cell piece picking can be walked by workman immediately, or this abnormal cell piece picking is walked by picking device, and the brake apparatus on PLC also can work immediately, material loading transmits and stops, and waits that taking follow-up the resuming of abnormal cell piece away serves material.
The beneficial effect that the utility model has:
