A Photocell Fixing and Alignment System

Abstract

The embodiment of the invention discloses a photoelectric tube fixing and tuning system which comprises a photoelectric tube including an emission port for emitting optical signals, and a slide rail arranged on the emission port and extending along the direction away from the emission port. The plane where the slide rail is situated is parallel to the optical signals emitted by the emission port. The photoelectric tube is further provided with an optical signal adjusting member which adjusts the projecting direction of optical signals. A scaled blocking sheet is detachably arranged on the slide rail, the plane, where the blocking sheet is situated, is perpendicular to the plane, where the slide rail is situated, and the distance between the blocking sheet and the emission port is adjustable. The projecting direction of the optical signals is detected by the blocking sheet and calibrated by the optical signal adjusting member, so that the position of the optical signals at a receiving terminal is quantitatively controllable, and an operator can conveniently find optical signals at the receiving terminal. The photoelectric tube is thus aligned with the receiving terminal.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a photoelectric cell fixing and alignment system. Background technique [0002] The photoelectric cell is a switching element used to realize non-contact detection in the automatic control system. Its working principle is as follows: figure 1 As shown, the photocell 1 transmits an optical signal L to the receiving end 2, and the receiving end 2 outputs a corresponding electrical signal according to the receiving state of the optical signal L, thereby realizing the conversion from an optical signal to an electrical signal. [0003] In steel smelting production line, such as figure 2 As shown, the photoelectric cell 1 and the receiving end 2 are respectively arranged on both sides of the slab roller table. If there is a slab 3 on the slab roller table, the optical signal L is blocked by the slab 3, so that the receiving end 2 cannot receive The optical signal L, and th...
