Description
Technical field
The utility model relates to the crystal silicon solar cell sheet printing technology, is specifically related to a kind of crystal silicon solar cell sheet and prints slurry online weighing system.
Background technology
The serigraphy of crystal silicon solar cell sheet refers to: utilize the non-graphic part silk screen hole sealing of screen printing forme can not see through slurry, the penetrating energy in picture and text part silk screen hole prints through the principle of slurry, the slurry of constant weight is printed onto on the crystal silicon solar energy battery.The silkscreen process of solar battery sheet needs the printing weight of slurry is monitored in actual production, every one hour the weight that is printed onto on the solar battery sheet is weighed once.Weighing of slurry of printing comprises weighing of following three points: weighing of the weighing of silver-colored aluminium paste, aluminium paste and weighing of silver slurry.Being printed onto slurry weight on the solar battery sheet directly influences welding quality and the conversion efficiency of battery sheet, therefore suitable weigh very necessary.Weighing method was manual weighing in the past, its concrete grammar is as follows: operator's hand is worn clean PVC gloves, sorting out the silicon chip that a slice do not print from the equipment that is moving weighs, and then print in the silicon chip used device that will weigh, the last silicon chip of sorting out again after the printing is weighed, weighing finishes in the silicon chip used device again, claims slurry weight=printing back weight-preceding weight of printing like this.
The Weighing method shortcoming of above-mentioned printing slurry is as follows:
(1) poor stability: manually weigh, need the operator to sort out silicon chip to be weighed from the equipment of operation, the silicon chip after will weighing is again put into the equipment of operation, and this process is brought hidden danger in the personal safety to the operator;
(2) weighing process is loaded down with trivial details, increases operator's workload: weighed once every one hour, need sort out silicon chip from equipment, put on the electronic scale, put in the equipment again and print, take out again and weigh, weigh and put in the equipment after finishing again, process is loaded down with trivial details, and workload is big;
(3) people's contact brings the pollution of silicon chip easily: because operating personnel's frequent contact meeting causes certain pollution to silicon chip, reduce the electrical property of silicon chip itself, influence every electrical quantity of finished product battery.
The utility model content
Technical problem to be solved in the utility model provides a kind of crystal silicon solar cell sheet convenient to operation and prints slurry online weighing system, when guaranteeing staff's personal safety, avoids silicon chip to be polluted, and increases work efficiency.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of crystal silicon solar cell sheet prints slurry online weighing system, comprises first LOAD CELLS that is installed in the preceding transmission belt of printing below, second LOAD CELLS, PLC controller and the display that is installed in transmission belt below after printing; The output terminal of described first LOAD CELLS, second LOAD CELLS is connected with the input end of PLC controller respectively; The output terminal of described PLC controller is connected with the input end of display.
First LOAD CELLS is fixedlyed connected with the cylinder that is arranged on the preceding transmission belt of printing below, second LOAD CELLS is fixedlyed connected with the cylinder that is arranged on transmission belt below, printing back, and described cylinder is controlled by the PLC controller.
Transmission belt and printing back transmission belt constitute by two transmission belts with gap before the printing, and the diameter of first LOAD CELLS and second LOAD CELLS is all less than the width in two transmission belt gaps.
The course of work of the present utility model and principle of work are as follows:
Every one hour the slurry that is printed on the silicon chip is weighed once, when weighing, the staff makes the cylinder action of first LOAD CELLS below by the button of operation PLC controller, thereby driving first LOAD CELLS rises and withstands and be positioned at before the printing silicon chip on the transmission belt and weigh, the weighing results real-time Transmission is given the PLC controller, weigh finish after, the staff makes the cylinder action of first LOAD CELLS below by the button of operation PLC controller, thereby drive first LOAD CELLS, the silicon chip that finishes of weighing is relay to be got back to before the printing on the transmission belt, be printed slurry through the printing table top then, be transferred to then on the transmission belt of printing back; Next the staff makes the cylinder action of second LOAD CELLS below by the button of operation PLC controller, thereby driving second LOAD CELLS rises and withstands the silicon chip that is positioned on the transmission belt of printing back and weigh, the weighing results real-time Transmission is given the PLC controller, weigh finish after, the staff makes the cylinder action of second LOAD CELLS below by the button of operation PLC controller, fall thereby drive second LOAD CELLS, the silicon chip that finishes of weighing is relay to be got back on the transmission belt of printing back; The PLC controller just can be according to weight before the silicon chip printing that records and printing back weight like this, calculate the slurry weight that is printed onto on the silicon chip, above-mentioned measurement result and result of calculation will show to display by PLC controller real-time Transmission, so that the staff carries out record.
The beneficial effect that adopts technique scheme to produce is: whole slurry weighing process need not the staff and contacts silicon chip, thereby avoids silicon chip to be polluted; Convenient to operation, need not the staff and be deep on the running production line and fetch silicon chip, guarantee staff's personal safety; Weighing system and production line are combined, realize onlinely weighing in real time, weighing results in time feeds back, high efficiency.
