Description
Technical field
The utility model belongs to the electrode printing equipment field of photovoltaic cell, is specifically related to a kind of screen process press.
Background technology
In manufacture of solar cells, the electrode printing is very important one procedure.At present, electrode making method commonly used comprises: silk-screen printing technique, evaporation process, laser grooving bury grid technique, electroplating technology and Wiring technique.
Silk-screen printing technique is best suited for being applied in the large-scale industrial production; And a kind of process that cost is minimum; Also be the technology that industry generally adopts, its basic principle is to utilize silk screen visuals mesh to pass through slurry, and non-graphic part mesh does not pass through slurry and prints.During printing, pour slurry into, apply certain pressure at the slurry position of silk screen, move towards the silk screen other end simultaneously with scraper at silk screen one end.Slurry is expressed on the substrate from the mesh of visuals by scraper plate in moving, owing to the stickiness effect of slurry makes the trace set within the specific limits.The printing process middle scraper is line with screen printing forme and stock all the time and contacts; Contact wire moves with scraper and moves; Owing to keep certain clearance between silk screen and the stock; Silk screen when making printing produces the reaction force to scraper plate through the tension force of self, and this reaction force is called screen resilience.Because the effect of screen resilience make silk screen and substrate only be portable line and contact, and other part of silk screen and stock is disengaged position, guaranteed the printed dimensions precision and avoided the stock of swiping.Scraper plate lifted after scraping whole printing zone, and silk screen also breaks away from substrate simultaneously, and workbench turns back to the material loading position, so far is a print stroke.
Screen process press mainly comprise transmission device, printing plate device, printing equipment, supporting arrangement promptly undertake the printing of platform, to version mechanism, drying device and electrical control gear.
Wherein, transmission device comprises motor, electromagnetic clutch, decelerator and speed adjusting gear.
Printing plate device mainly comprises forme clamper, forme lift, to the version guiding mechanism with lift the net compensation mechanism.Printing plate device is used for fixing screen printing forme, in printing process, realizes taking off that the book formula is risen and fallen or level is gone up and down.
Printing equipment comprises scraper, scraper pressure control system, guiding mechanism and scraper inversion mechanism; The following mechanism of general employing of scraper pressure control system: toggle, slider-crank mechanism, chain sprocket mechanism and plunger magnetic force cylinder, to realize the printing reciprocating stroke; The following form of the general employing of guiding mechanism: roller grooved rail, two axis of guide and the axis of guide add slide block.Printing equipment includes to be scraped ink system and returns ink system, and scraper comprises doctor and returning blade, and wiping and Hui Mo are the main actions that realizes silk-screen, and in reciprocating motion, doctor and returning blade alternately rise and fall, and realizes wiping respectively and returns the China ink action.
The supporting arrangement platform of promptly undertaking the printing of: be used for fixing stock, have stock positioner, podium level and level(l)ing device.
To version mechanism: move the position of platform during to version, generally leans on the mechanical whorl turn to realize, and reliable locking device and displacement guiding (dovetail groove or feather key etc.) should be arranged.
Drying device: infrared electric heating pipe hot-air seasoning or ultraviolet light polymerization drying unit.
Electrical control gear: comprise that operation cycle is controlled, doctor position is controlled gentle pressure-controlled.
The equipment vendors of screen process press are many, and at present, that in the production of silica-based battery, mainly selects for use has ASYS, Baccini, a DEK etc.
Based on the cell integrated Effect on Performance of electrode pair; People have carried out continuous improvement and optimization on the design of electrode and manufacture craft; Wherein a kind of effective optimization is exactly the width that reduces positive thin grid; To reduce the shading area,, improve the height of grid line simultaneously in order to guarantee the electric property of grid line as far as possible.So on the basis of typography, people have developed the secondary printing technology of suitable suitability for industrialized production.
At present; The main alignment function of realizing that adopts CCD (Charge-coupled Device charge coupled cell) navigation system in the secondary printing equipment; Its principle is to adopt the CCD monitoring; Through regulating workbench or half tone on-chip mark is overlapped with mark on the test pattern, thereby realize accurate contraposition, the CCD aligning accuracy can reach ± 0.01mm.But; The secondary printing equipment of available technology adopting CCD navigation system has following shortcoming: need prefabricated mark on substrate and figure; Can there be alignment error in the manufacturing process, adds the alignment error of CCD itself, the alignment precision in the time of can influencing final the printing; The CCD system cost is expensive, nearly 30,000 dollars of a cover CCD navigation system; CCD seeks mark to adjusting camera position according to substrate on time, and operation is comparatively complicated, influences production efficiency; Adopt the CCD alignment system, after one-step print is accomplished, need substrate be taken out from workbench; Put into baking oven, after the oven dry, put back to again and carry out the secondary printing after workbench is aimed at; Be not suitable for flexible parent metal, because, in the prebake process; Thermal stress and the alignment precision when repeatedly fetching process very easily causes flexible substrates distortion, this distortion to have a strong impact on the secondary printing, even cause can't the secondary printing.
