47 results about "Check sheet" patented technology

The check sheet is a form (document) used to collect data in real time at the location where the data is generated. The data it captures can be quantitative or qualitative. When the information is quantitative, the check sheet is sometimes called a tally sheet.

Piezoelectric pump and electronic product

The invention provides a piezoelectric pump and an electronic product, and relates to the technical field of piezoelectric components. The piezoelectric pump comprises a first cover plate, a piezoelectric element and a second cover plate. An air inlet hole is formed in the first cover plate, and an air outlet hole is formed in the second cover plate. The edge of the piezoelectric element is located between the first cover plate and the second cover plate, and fixed by the first cover plate and the second cover plate. The piezoelectric element comprises a piezoelectric vibrator and an annular check sheet, the piezoelectric vibrator comprises a vibration diaphragm and an annular piezoelectric, and the vibration diaphragm is attached to the edge of the annular piezoelectric. Air vents are formed in the vibration diaphragm, the annular piezoelectric is located on one side, facing the first cover plate, of the vibration diaphragm and recedes the air vents, and the annular piezoelectric is used for generating the vibration quantity after being triggered and transmitting the vibration quantity to the vibration diaphragm. The annular check sheets are arranged on one side, close to the second cover plate, of the vibration diaphragm, and cover the positions above the air vents of the vibration diaphragm in an opening and closing mode. The piezoelectric pump is simple in structure, smallin size and low in power consumption, the phenomenon that opening and closing of a valve body is hysteretic does not occur, and the pump output is large.

Check sheet feeding device and control method thereof

The invention relates to the technical field of water pump automatic assembly, in particular to a check sheet feeding device. The check sheet feeding device comprises a rack, a feed vibration disc, afeed direct vibrator, a feeding mechanism, a detection device and a controller. The feed vibration disc and the feed direct vibrator are mounted on the rack. The feed vibration disc comprises a storage bin used for storing check sheets and a vibration disc connected with an outlet of the storage bin. The tail end of the vibration disc is connected with the feed direct vibrator. The feeding mechanism is located at the tail end of the feed direct vibrator. The detection device is located above the feeding mechanism. A detection mechanism detects the directions of the check sheets. The feeding mechanism and the detection device are connected with the controller. A control method of the check sheet feeding device comprises the steps that (A) a core shaft and a sleeve descend; (B) the check sheets are detected; (C) a mechanical claw is closed; and (D) the core shaft and the sleeve ascend. The check sheet feeding device has the substantial effects that a long check sheet queue is formed on the feed direct vibrator so as to avoid supply interrupting; and the vibration frequency of the feed direct vibrator is automatically adjusted, and slow supply is avoided.

Anti-counterfeiting coin/seal with perspective amplified pattern

The invention discloses an anti-counterfeiting coin/seal, and in particular relates to an anti-counterfeiting coin/seal with a perspective amplified pattern. The anti-counterfeiting coin/seal with the perspective amplified pattern consists of a coin or seal with an anti-counterfeiting pattern, and a micro lens array checking sheet for observing the anti-counterfeiting pattern, wherein the checking sheet and the coin or seal are respectively used independently and coordinately; the structure of the coin or seal with the anti-counterfeiting pattern is that a micro-pattern anti-counterfeiting pattern is directly printed on the surface of the coin or the seal; the structure of the micro lens array checking sheet is that a micro lens array structure is processed on a transparent medium sheet; and the specification of the micro lens of the checking sheet is matched with the structural dimension of the anti-counterfeiting micro-pattern. The amplified micro-pattern anti-counterfeiting information on the surface of the coin can be seen through the micro lens array of the checking sheet, and the amplified anti-counterfeiting pattern has a special effect of a three-dimensional shifting state by moving relative positions of an observation point and the coin. The anti-counterfeiting coin/seal has the better anti-counterfeiting effect and is convenient to identify.
