Abstract
The utility model discloses a positioning tool of an electrode printing station on the front face of a silicon wafer printing machine. The positioning tool of the electrode printing station on the front face of the silicon wafer printing machine comprises a vacuum sucking cup which is used for fixing a silicon wafer, a plurality of air holes are formed in the upper surface of the vacuum sucking cup 1, and the air holes are communicated with a printing machine vacuumizing device and a printing machine air supply system. The positioning tool is communicated with the vacuumizing device in the positioning process, silicon wafers can be absorbed to be positioned so that processing can be facilitated, after processing is completed, the vacuumizing device is switched off and cut off, the vacuum chuck is communicated with the air supply device at the same time when an ejection rod is used for ejecting upwards, the silicon wafers are ejected upwards by air flow, under the simultaneous action of the air flow and the ejection rod, it can be guaranteed that the silicon wafers can be taken out quickly and completely, and the damage rate of workpieces can be greatly lowered in the discharging process.
Description
Technical field
The utility model relates to semi-conducting material processing field, is specifically related to a kind of positioning tool of silicon slice printer front electrode printing station.
Background technology
Along with the technological accumulation of recent decades of semiconductor equipment industry, photovoltaic apparatus enterprise possesses the whole line equipment capability of solar cell manufacturing equipment substantially.Photovoltaic solar silicon slice printer has been widely used in the print production of photovoltaic solar silicon chip, one of step of the most critical of printing photovoltaic solar silicon chip is at the very meticulous circuit of the front and back manufacture of silicon chip, this metal coating technique is completed by screen printing technique conventionally, and the electrocondution slurry that is about to contain metal sees through screen mesh and is stamped in and on silicon chip, forms circuit or electrode.As can be seen here, the quality of photovoltaic solar silicon chip largely depends on the equipment quality of photovoltaic solar silicon slice printer.
The work stage upper surface of existing printing machine front electrode printing station is provided with the pore being connected with vacuum-pumping tube, silicon chip and the laminating of work stage upper surface during operation, silicon chip is vacuum suction location under the effect of pore, after being completed for printing, stop vacuumizing, the elevating lever of work stage bottom ejects work stage by silicon chip.But because the bottom surface of silicon chip is level and smooth, no longer vacuumize although machine rear work stage, the bottom surface of silicon chip still can be tight with work stage laminating, if the too tight silicon chip that easily damages of both laminatings when elevating lever ejects silicon chip causes waste product.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of positioning tool of silicon slice printer front electrode printing station, and workpiece loading and unloading is simple fast, and workpiece is not caused to damage, spoilage while greatly reducing workpiece discharging.
The utility model is achieved through the following technical solutions:
The positioning tool of silicon slice printer front electrode printing station, comprises that the upper surface of vacuum cup 1 is provided with some pores for the fixing vacuum cup of silicon chip, and described pore is communicated with printing machine vacuum extractor, printing machine supply air system.
The further improvement project of the utility model is, described vacuum cup is provided with air inlet, the gas outlet being communicated with pore, described air inlet is connected with described printing machine supply air system by tube connector, described gas outlet is connected with described printing machine vacuum extractor by another root tube connector, is all provided with the control valve being electrically connected to described printer control system on described tube connector; Or described vacuum cup is provided with a blowing mouth being communicated with described pore, described blowing mouth is connected with the outlet of reversal valve by tube connector, and two imports of described reversal valve are connected with described printing machine vacuum extractor, printing machine supply air system by tube connector respectively.
The further improvement project of the utility model is, described reversal valve is connected with the time relay, and the described time relay is electrically connected to the control system of printing machine.
The utility model compared with prior art has the following advantages:
The utility model is communicated with vacuum extractor when location, can adsorb silicon chip makes its location be convenient to processing, after machining, close cut-out vacuum extractor, when push rod makes progress jack-up, sucker is communicated with air supply plant, with the air-flow top silicon chip that makes progress, in air-flow and push rod, under effect, can guarantee silicon chip complete taking-up fast, greatly reduce the spoilage of workpiece when discharging.
