Photoelectric sensor of infrared LED light source range finding

Abstract

The invention discloses a photoelectric sensor of an infrared LED light source range finding and relates to the infrared range finding sensor technology field. The photoelectric sensor of the infraredLED light source range finding comprises a sensor shell. A pedestal is fixed to a bottom of the sensor shell. A signal connection port is installed on one side of an outer portion of the pedestal, and fixing plates are fixed at two side positions of the outer portion, which is close to the signal connection port, of the pedestal. One side of an inner portion of the sensor shell is provided with an infrared LED lamp. A photosensitive receiver is installed on one side of the sensor shell relative to the infrared LED lamp, and a connecting plate is fixed at a middle position of a top of the sensor shell. The infrared LED lamp and the photosensitive receiver can be protected through an effect of tempered glass plates in a first block cover and a second block cover so as to improve sensitivityand accuracy when a device is used, and stability of the first block cover and the second block cover during a usage process can be increased through the connecting plate.

Description

technical field [0001] The invention belongs to the technical field of infrared ranging sensors, in particular to a photoelectric sensor for infrared LED light source ranging. Background technique [0002] Infrared ranging sensor is a sensing device, which is a measuring system using infrared rays as the medium. It has a wide measuring range and short response time. It is mainly used in modern technology, national defense and industrial and agricultural fields. [0003] In the Chinese patent No. 201721257707.6, a photoelectric sensor for infrared LED light source distance measurement is disclosed. The patent describes that "the present invention is provided with a device with a shock-absorbing effect, which can prevent the device from being rigidly connected to the device. When vibrating, it can reduce the impact, avoid the sensor from being damaged, and improve the service life of the device.” However, during the vibration process of the device, the data line at the sensor ...
