Description

Technical Field

[0002] The through-beam photoelectric sensor is a photoelectric switch composed of a light emitter and a light receiver, also known as a through-beam separation photoelectric switch. The detectable distance of the through-beam photoelectric sensor is relatively large, generally up to several meters or even tens of meters. When in use, the light emitter and the light receiver are installed on both sides of the path through which the object to be detected passes. When the object to be detected passes, the light path is blocked, and the light receiver is activated to output a switch control signal. Through-beam photoelectric sensors are widely used in the fields of photoelectric readout, photoelectric coupling, grating ranging, laser alignment and machining equipment.

[0003] Through-beam photoelectric sensors are generally installed on mechanical equipment through a fixing device. In the prior art, the fixing device usually adopts a mounting bracket. The through-beam photoelectric sensor is connected to the equipment through the mounting bracket by bolts. When the equipment needs to install the through-beam photoelectric sensor, such a mounting bracket needs to drill a pair of holes on the same axis on both sides of the equipment in advance. When drilling the holes, it is necessary to check whether they are on the same axis several times to avoid misalignment of the holes, which will cause the light emitter and the light receiver to not cooperate. At the same time, it is also necessary to drill holes on the mounting bracket to install the mounting bracket on both sides of the equipment. At the same time, the through-beam photoelectric sensor also needs to be fixed to the mounting bracket by screws. This leads to the problem that the fixing device used for the through-beam photoelectric sensor in the prior art not only has the problem of cumbersome installation and disassembly process with the mechanical equipment, but also the problem of cumbersome installation and disassembly process between the through-beam photoelectric sensor and the fixing device.

[0004] In the utility model with application number: CN201822164743.9 and publication number: CN209372101 U, a photoelectric sensor fixing seat is disclosed, including a fixing seat body, on which is provided a channel for a detection object to pass through and at least a pair of first mounting holes for mounting the photoelectric sensor, each pair of first mounting holes is connected to the channel, and the central axes of each pair of first mounting holes coincide and are distributed in the upper and lower spaces.
