Laser pick-off head includes receiving lens, the second screw thread metal pipe, optical fiber. Receive capabilities main body includes receive capabilities circuit board, receive capabilities housing, laser pick-off pipe. Laser pick-off head and receive capabilities main body are connected by optical fiber, it is achieved the separation of the two, and optical signal passes to laser pick-off pipe by optical fiber.
After the energising of Laser emission sensor, emission function circuit board is started working, and laser diode sends laser, and laser is focused on by diversing lens and forms laser beam injection.After the energising of laser pick-off sensor, receive capabilities circuit board is started working, the laser that laser beam emitting head sends is by focusing on after the reception lens of laser pick-off head, concentrate and inject lens optical fiber below, and by optical fiber, laser signal is passed to laser pick-off pipe, process output switching signal through receive capabilities circuit board.

Detailed description of the invention:
A kind of separate type correlation laser photoelectricity switch, including Laser emission sensor, laser pick-off sensor. Laser emission sensor includes laser beam emitting head, emission function main body, power line. Laser pick-off sensor includes laser pick-off head, receive capabilities main body, power line and holding wire. Laser beam emitting head separates with emission function main body, and laser pick-off head separates with receive capabilities main body.
Laser beam emitting head includes laser diode (2), the first screw thread metal pipe (1), diversing lens (3). Emission function main body includes emission function circuit board (5), emission function housing (6). Laser beam emitting head and emission function main body are connected by electric wire (4), it is achieved the separation of the two. After the energising of Laser emission sensor, emission function circuit board (5) is started working, and laser diode (2) sends laser, forms parallel laser light beam by the focusing of diversing lens (3).
Laser pick-off head includes receiving lens (8), the second screw thread metal pipe (7), optical fiber (9). Receive capabilities main body includes receive capabilities circuit board (12), receive capabilities housing (11), laser pick-off pipe (10). Laser pick-off head and receive capabilities main body are connected by optical fiber (9). After the energising of laser pick-off sensor, receive capabilities circuit board (12) is started working, the laser that laser beam emitting head sends is focused on afterwards by the reception lens (8) of laser pick-off head, concentrate and inject lens optical fiber (9) below, and by optical fiber (9), laser signal is passed to laser pick-off pipe (10), process output switching signal through receive capabilities circuit board (12). If having detection object through being blocked by laser, laser pick-off head is not received by laser, then output signal is contrary. Laser beam emitting head adopts the diversing lens (3) of undersized laser diode (2) and diameter 3mm, is assembled in the first screw thread metal pipe (1), the diameter of whole laser beam emitting head can be made to accomplish 4mm. Reception lens (8) and diameter that laser pick-off head adopts diameter to be 3mm are 2.2mm optical fiber (9), are assembled in the second screw thread metal pipe (7), it is possible to the diameter of laser pick-off head is accomplished 4mm.So undersized emitting head and receive head substantially reduce installation volume, for installing space very narrow and small in the case of very applicable. It is arranged in narrow space by laser beam emitting head and laser pick-off head sense object, then passes through the function body outside space to process signal, drive ancillary equipment and the devices such as relay, buzzer, display lamp.
In laser pick-off sensor, owing to functional circuit is subject to various electromagnetic interference, if directly laser pick-off pipe (10) being contained in laser pick-off head, run wires to, on receive capabilities circuit board (12), just to ensure the stable performance of receive capabilities circuit board (12). So adopting optical fiber (9) laser pick-off head and receive capabilities main body to be connected, optical fiber (9) is not by the interference of electromagnetism, laser pick-off pipe (10) is connected on receive capabilities circuit board (12), thus avoid above-mentioned electromagnetic interference problem, substantially increase stability and the capacity of resisting disturbance of product. Owing to optical fiber (9) receiving plane diameter is less, so laser focusing being projected on optical fiber (9) receiving plane above arranging reception lens (8), ensure the intensity of laser signal, improve distance of reaction, make distance of reaction up to more than 30 meters, owing to the luminous point of laser is only small, thus remote accurately detection can be realized, it is highly suitable for those build requirements little, the Environment Science industry that precision requirement is high.
