Abstract
The utility model discloses a non-contact type photoelectric paper thickness measurement device, in particular a paper thickness measurement device used for optical character readers, intelligent character readers, currency count machines and information collection machines with paper. The device comprises an upper supporting frame, a lower supporting frame, an infrared diode and a circuit board. The upper supporting frame and the lower supporting frame form into a whole and have a certain distance, the paper thickness can simply be measured by the paper passing through the gap of the upper supporting frame and the lower supporting frame. The device can improve the accuracy of the measurement, can be conveniently debugged as a whole, can be arranged on a mainframe at any time after the debugging is finished; has a simple structure, convenient maintenance and low cost; detects the thickness of the papers and is used for overlapping detection of the papers.
Description
Technical field
The utility model relates to a kind of sheet thickness measuring device that uses in scanner, optical character reader (OCR), intelligent character reader and other paper feed information collection machine, specifically non-contact type photoelectricity paper thickness measuring device of being applied in.
Background technology
At present, paper thickness measuring device kind is a lot, but they all are to measure in the mode of contact mostly, when paper can have wearing and tearing to apparatus surface by its surface, reduce chart drive speed and measuring accuracy, and serviceable life is low, solution hanging togother that can not be very desirable detects problem.
The utility model content
Technical matters to be solved of the present utility model is at the prior art weak point, and non-contact type photoelectricity paper thickness measuring device is provided, and reduces maintenance cost, and raising is low serviceable life; Simple in structure, be quick on the draw; Can effectively measure the thick and solution hanging togother detection problem of paper.
The technical scheme that its technical matters that solves the utility model adopts is: non-contact type photoelectricity paper thickness measuring device, bracing frame, infrared reception, emitting diode, circuit board up and down, the infrared receiving/transmission diode adopts one two receipts each other, the infrared transmission of test paper and reflected value, thus paper thickness detected; Described infrared reception, emitting diode are installed on the circuit board, and circuit board is fixed on upper and lower bracing frame, and upper and lower bracing frame is installed on the main frame.
Between the described upper and lower bracing frame certain distance is arranged, can separate independent assembling and also can whole assemble, two parts also can be used as the autonomous device use up and down.
Described infrared reception, emitting diode can be formed multi-to-multi and send out the form of overcharging, and also detect the infrared external reflection of paper except that detecting the paper infrared transmission.
The utility model is owing to adopt said structure, when paper passes through its measured zone, infrared receiving diode receives infrared-emitting diode respectively by transmitted light and reflected light behind the paper, signal is uploaded control circuit, by calculating paper infrared optical transmission and reflected value are obtained the thick value of effective paper then.
Non-contact type photoelectricity paper thickness measuring device of the present utility model is compared with prior art, has following beneficial effect:
The beneficial effects of the utility model are, because measurement mechanism is to the non-cpntact measurement of paper, paper can improve measuring accuracy and serviceable life under the prerequisite that does not reduce chart drive speed, and simple in structure, process simple, easy for installation, easy-maintaining, cost is low; Can effectively solve the detection problem of hanging togother.
Description of drawings
Accompanying drawing 1 is the structural representation of non-contact type photoelectricity paper thickness measuring device.
Embodiment
Next explain below with reference to Figure of description non-contact type photoelectricity paper thickness measuring device of the present utility model being done.
Referring to accompanying drawing, the utility model device comprises: infrared receiving/ transmission diode 3,4,6,7 is installed in respectively above the circuit board 2,8, and circuit board 2,8 is fixed on upper support frame 1 and lower support frame 5, and upper support frame 1 and lower support frame 5 are installed on the main frame.
Referring to accompanying drawing, the course of work of the utility model device is as follows: regulate certain distance between upper support frame 1 and the lower support frame 5 and be installed on the main frame, infrared receiving/ transmission diode 3,6,7 is formed one group, infrared receiving/ transmission diode 3,4,7 is formed one group, adopt one two receipts each other, test paper is to the reflection strength of infrared optical transmission and pros and cons, thereby the right value that obtains paper sheet thickness is to solve the overlapping detection problem of paper.
Referring to accompanying drawing, the utility model device can separate independent assembling and also can whole assemble, and two parts also can be used as the autonomous device use up and down.
