In the existing multilayer optical scanning sensing device, the laser emission sources of all the distance measuring devices share one emission lens, the laser receiving ends of all the distance measuring devices share one receiving lens, and the inclination angles of the optical axes of the laser beams emitted by all the distance measuring devices are different. This leads to a problem that the lens has a large volume and mass, the mass distribution of the rotating body is not uniform, the structural strength is not high, the stress of the rotating mechanism is not uniform when side mounting or inclined mounting is adopted, and the reliability is obviously reduced; meanwhile, the distance measuring capability of the laser transmitter and the laser receiver distributed at the edge is different from that of the laser transmitter and the laser receiver distributed in the middle. In the technical solution of the present invention, as shown in fig. 2, the optical transceiver assembly 30 includes a housing 31, and a laser transmitter 32, a laser receiver 33, a transmitting lens 34, a receiving lens 35 and a transceiver circuit board 36 mounted on the housing 31, where the transceiver circuit board 36 is electrically connected to the laser transmitter 32 and the laser receiver 33, respectively, and the transceiver circuit board 36 is used to control the laser transmitter 32 to transmit a laser signal and control the laser receiver 33 to receive the laser signal. Therefore, each optical transceiver module 30 is relatively independent, each optical transceiver module 30 is a modular module, the optical transceiver modules 30 are symmetrically arranged around the rotating mechanism 20, the mass distribution is uniform, the assembly and debugging are convenient, and the consistency of the distance measuring capability of each optical module is good.

Under the condition that the product structure is shaped, the pitch angle of the optical transceiving component 30 can be combined into different scanning layers and scanning frequencies according to the requirements of customers only by adjusting the pitch angle, so that the ultrahigh-speed single-layer planar optical scanning sensing device can be realized, and the application scene can be conveniently expanded.

The optical axis of the laser transmitter 32 is parallel to the optical axis of the laser receiver 33, the light exit surface of the laser transmitter 32 is located at the focus of the transmitting lens 34, and the photosensitive surface of the laser receiver 33 is located at the focus of the receiving lens 35. When the measuring circuit board 60 is used, the laser transmitter 32 is controlled by the measuring circuit board 60 to emit laser, the laser is converged into approximately collimated light through the transmitting lens 34, the light is subjected to diffuse reflection through a measured object, part of the diffuse reflection light enters the receiving lens 35 and is converged to the laser receiver 33, and transmitting and receiving signals are converged to the transceiving circuit board 36 to be resolved, so that one-time optical measurement is completed.

In the existing multilayer optical scanning sensing device, there is also a problem that the laser emitting components on the optical path need to be in one-to-one accurate correspondence with the laser receiving components, which makes the installation and adjustment difficult. And the pitch angle of each scanning layer is determined by the mounting position of the laser transmitter of the transmitting assembly behind the transmitting lens, the mounting space of the transmitting assembly is narrow, the available mounting position is completely determined by the structural design, and the pitch angle of each scanning layer cannot be adjusted. In the solution of the present invention, the housing 31 is rotatably mounted on the rotating mechanism 20 through the adjusting rotating shaft 37, so as to facilitate adjustment of the scanning pitch angle of each optical transceiver module 30, and the optical transceiver module 30 precisely adjusts the scanning pitch angle through the adjusting rotating shaft 37. Preferably, only the unfixed end piece 38 is further provided on the housing 31, the adjusting shaft 37 is connected to the rotating mechanism 20, and after the scanning pitch angle of each optical transceiver module 30 is adjusted, the unfixed end piece 38 is connected to the measurement circuit board 60. As shown in fig. 2, a transmitting light cavity 391 and a receiving light cavity 392 corresponding to the laser transmitter 32 and the laser receiver 33, respectively, are further formed in the housing 31.

The scanning pitch angles formed by the emission optical axis of each optical transceiver module 30 and the zero-degree scanning surface a are different and are increased from the minimum value to the maximum value according to the preset increasing amplitude, the scanning pitch angle of each optical transceiver module 30 is accurately adjusted through the adjusting rotating shaft 37, and after the adjustment is finished, the optical transceiver module is fixedly reinforced with the rotating mechanism 20.

Since the optical scanning sensing device will generate a certain vibration due to uneven mass distribution during the rotation process, in the technical solution of the present invention, the optical scanning sensing device further includes a counterweight adjusting device 80, and the counterweight adjusting device 80 is installed on the rotation mechanism 20 for adjusting the rotation balance. Optionally, the counterweight adjusting devices 80 are disposed at two ends of the rotating mechanism 20, so as to balance mass distribution, reduce vibration amplitude, and improve reliability and service life of the optical scanning sensing device. The counterweight adjusting device 80 is installed at an appropriate position of the upper and lower ends of the rotating mechanism 20, and the installation position and angle can be finely adjusted to balance the dynamic unbalance amount of the rotating mechanism 20 rotating along the rotating shaft.

From the above, the optical scanning sensing device of the invention can realize multi-layer conical surface scanning, and has the advantages of high structural strength, high reliability, whole machine service life, high scanning frequency, easy assembly, flexible adjustment of the pitch angle of each scanning surface, and realization of a single-layer plane optical scanning sensing device with multiplied scanning frequency.

Alternatively, the basic parameters of the optical scanning sensor device can be referred to as follows: the rated rotation speed is 15 circles/second, and the measuring frequency of the single optical transceiver component 30 is 36 KHz.

After receiving the primary start measurement signal, the transceiver circuit board 36 on the optical transceiver module 30 controls the laser transmitter 32 to transmit laser, and the laser is collimated into approximately parallel light after passing through the transmitting lens 34. The light reaches the object to be measured and is subjected to diffuse reflection, and part of the diffuse reflection light enters the receiving lens 35 and is converged on the photosensitive surface of the laser receiver 33. The transmitting signal and the receiving signal are obtained by the transceiving circuit board 36, the measurement result is obtained through mathematical calculation, and the measurement result is output to the user through the wireless signal transmission part 40. In the process, wireless power supply and wireless signal transmission are adopted, and compared with the method that a metal friction type conductive slip ring is used, the metal friction type conductive slip ring is not in physical contact, abrasion is not generated, and the rotating speed of the rotating mechanism 20 is not limited.
