Method for solving problem of EL (electroluminescent) black spots of PERC (passivated emitter and rear cells)

The invention belongs to the field of solar cell manufacture, and particularly relates to a method for solving the problem of EL (electroluminescent) black spots of PERC (passivated emitter and rear cells). The method has the advantages that the aperture sizes of spray pins of water films are 0.8 mm, water film devices can slowly cover silicon wafers, the silicon wafer covering water spray pressures of the water films can be relieved, the silicon wafer laying pressures can be reduced, undesirable conditions that existing water films are splashed all around to contaminate existing surrounding silicon wafers can be effectively reduced on the premise that consistent water flow is guaranteed, and the problem of the EL black spots of the PERC can be effectively solved by the aid of the method;the pressures of the water film devices can be relieved, the problem of falling of existing spray pins of the existing water films can be effectively solved, the problem of long-time pinhole blockingcan be solved, over-etching due to insufficient water volumes can be prevented, equipment staffs only need to carry out irregular replacement and maintenance, and accordingly the time and labor can besaved; the problems of water film splashing, belt and silicon wafer contamination and etching contamination due to excessively high power and high pressures of the existing water films can be solved,the yield of efficient single crystals can be increased, the efficiency of the efficient single crystals can be improved, and the method has a broad application prospect.

Tablet filling device, PTP packaging machine, and method for manufacturing a PTP shee

The present invention addresses the problem of providing a tablet filling device, a PTP packaging machine, and a method for manufacturing a PTP sheet, with which it is possible to suppress a decreasein the appearance quality of a tablet printed on both surfaces. The tablet filling device (21) is provided with: a first rotating cylinder (47) that sucks and holds tablets (5) supplied from a supply/dispensing unit (46) and transports the tablets; a first printing mechanism (50) that prints on one surface of the tablet (5) conveyed by the first rotating cylinder (47); a second rotating cylinder (48) capable of transferring the tablets (5) that have been printed on one surface thereof by the rotating cylinder (47), holding the tablets (5) by suction, and conveying the tablets (5); a second printing mechanism (51) that prints on the other surface of the tablet (5) conveyed by the second rotating cylinder (48); and a third rotating cylinder (49) that inverts the tablet (5), which has been transferred by the second rotating cylinder (48) and printed on both surfaces, so as to fill the bag section (2) of the container film (3) with the inverted tablet (5) in such a manner that the other surface printed by the second printing mechanism (51) is positioned on the upper side.

Tablet press and feeding detection device and ventilation device thereof

PendingCN110978604ATimely stop lossWell ventilated structureShaping pressThermodynamicsTableting
The invention belongs to the technical field of tablet presses, in particular to a tablet press and a feeding detection device and ventilation device thereof. A ventilation opening is formed in the tablet press, an airflow driving function of a dust remover is utilized, airflow in a driving cabin and airflow in a lower cabin of the tablet press are driven to flow, good heat dissipation and ventilation in the tablet press are achieved, heat accumulation in the tablet press is reduced, and the probability that parts of the tablet press are damaged or defective products are produced due to the high temperature is reduced; and a temperature switch, a lower cabin air outlet door linked with the temperature switch, and a lower cabin air inlet door which can be opened and closed as required arearranged, so that the lower cabin can be internally ventilated and cooled only when the temperature is too high, and the lower cabin air inlet door and the lower cabin air outlet door are closed whenthe temperature is not too high, so that the internal environment of the lower cabin is kept clean to the greatest extent. According to the feeding detection device, a proximity switch is arranged ina discharging pipeline, and an alarm is linked to identify and raise alarm against an insufficient state of the materials, so that the yield is improved.

Buckling process for disposable absorbent article fixed patches

ActiveCN103350802BImprove stabilityEfficiently adjust the distancePackagingRelative displacementEngineering
The invention relates to the producing and manufacturing field of disposable absorbent articles, in particular to a buckling process for disposable absorbent article fixed patches. The buckling process is simple in operation mode, and capable of effectively enabling the fixed patches to be buckled tightly and enabling the fixed patches not to be separated easily in production. The buckling process includes the first step of tucking up the fixed patches of the produced disposable absorbent articles, then pressing down the fixed patches by means of a pressing plate, and enabling buckling bodies of two pairs of opposite fixed patches to be buckled with plush faces, the second step of inputting the disposable absorbent articles to a twisting device, conveying the disposable absorbent articles through the twisting device, enabling the upper surfaces and the lower surfaces of each pair of fixed patches of the disposable absorbent articles to carry out relative displacement movement by means of the twisting motion of the twisting device, namely, each buckling body generates the relative displacement movement with the plush faces, wherein the time of the relative displacement movement is 0.05-0.5 second, and then continuing to convey the disposable absorbent articles, and the third step of outputting the disposable absorbent articles from the twisting device and inputting the disposable absorbent articles to a folding process.
