Utility model content
The purpose of this utility model is to provide a kind of optoelectronic induction sensor, adopts combined type by photophore and receiver, facilitates the dismounting in later stage, maintenance, improve accuracy of detection simultaneously, the paper of different colours, size and fineness can be detected.
In order to achieve the above object, the utility model provides following technical scheme:
A kind of optoelectronic induction sensor, comprise transmitter, receiver, transmitter optical element, receiver optical element and circuit board, circuit board is arranged transmitter socket and receiver socket, transmitter, receiver are connected with transmitter socket, receiver socket removably respectively, transmitter optical element is arranged on the front end of transmitter, and receiver optical element is arranged on the front end of receiver.Adopt removably to be connected with circuit board with receiver by transmitter, when a certain component wear, easy dismantle this damage element, without the need to by whole element replacement.The light utilizing transmitter optical element to make to launch reduces scattering, reduces energy loss, adopts the light Relatively centralized that receiver optical element makes the paper be detected fire back, and reduces the impact of the factor such as color, size, surface smoothness of paper.
Further, receiver is position sensor.When paper is too small, or when the utility model cannot be arranged on the centre position of detected paper, the light part that transmitter is launched is transmitted into paper, and some is transmitted into the background artifacts on paper side.The light of returning from paper reflection and the light reflected from background object can arrive two diverse locations of receiver by optical element, receiver adopts position sensor, two light can be judged, and this light and the numerical value set in advance are compared, thus background artifacts and detected paper are made a distinction by the utility model, improve the precision detected.
Further, optical element is lens.
Further, circuit board arranges output interface, also comprise wire, the two ends setting of wire and interface, i.e. the interface of one end is connected with output interface.The length of wire can adjust according to the needs used.Circuit board and wire adopt assembly type to be connected, for convenience detach.
Further, transmitter comprises diode, and its quantity is two or more.As time goes on, diode is when sending light, and the light of transmission can be more and more weak, when it is attenuated to critical value, just needs to change it.Due to the utility model in use, its distance detected is fixing, by increasing the number of diodes in transmitter, enhancing the intensity emitted beam, when same extinction efficiency, reducing the decline cycle of transmitter.
Further, also comprise shell, shell arranges opening, transmitter, receiver, transmitter lens, receiver lens and circuit board are all arranged on enclosure, and the output interface on circuit board is arranged on aperture position.
The beneficial effects of the utility model are:
1) adopt detachable mode to be connected with circuit board with receiver by transmitter, when wherein a certain component wear, easily this damage element of dismounting, without the need to by whole element replacement;
2) light utilizing transmitter optical element to make to launch is scattering, reduces energy loss, adopts the light Relatively centralized that receiver optical element makes the paper be detected fire back, and reduces the impact of the factor such as color, size, surface smoothness of paper;
3) adopt position sensor that background artifacts and detected paper are made a distinction by the utility model, improve the precision detected;
4) quantity increasing diode in transmitter reduces the decline cycle of transmitter.
