Lockable control shielding device for infrared receiver of assembly line

Abstract

The invention discloses a lockable control shielding device for an infrared receiver of an assembly line. A bracket is arranged on a fixing base. A rotating shaft is connected between the fixing baseand the bracket. A shielding piece is fixedly connected to the rotating shaft. A rotating disc is fixedly connected to the rotating shaft. A pair of notches are formed in the rotating disc. An elasticpiece is fixedly connected to the bracket. A movable piece is fixedly connected to the tail end of the elastic piece. One end of the movable piece is matched with the notches, and the other end of the movable piece is provided with a through hole. A locking cylinder is rotationally arranged on the fixing base. A shifting rod is arranged on the locking cylinder. The shifting rod is inserted into the through hole. According to the lockable control shielding device for the infrared receiver of the assembly line, the locking cylinder is arranged on a body, the locking cylinder is opened, the shifting rod pulls out the movable piece, the shielding piece can be adjusted freely and rotate, the rotating shaft cannot rotate after the lock cylinder is locked, and the position of the shielding piececannot be adjusted at will. In this way, the misoperation of workers of the assembly line is avoided, and thus the orderly and stable operation of the assembly line is ensured.

Description

technical field [0001] The invention relates to a lockable control shutter for an assembly line infrared receiver. Background technique [0002] The infrared receiver is a device that can receive infrared signals and can independently complete from infrared reception to output compatible with TTL level signals. Infrared receivers and transmitters are installed on the assembly line to sense the flow of the product, but in special cases, in order to control the operation of the assembly line, the receiver needs to be manually blocked. At present, the main method is to block the receiver with a block, but this kind of The practice is easy for workers to remove the cover at will, which can easily lead to disorder in the production process and even lead to safety accidents. SUMMARY OF THE INVENTION [0003] The present invention mainly solves the technical problems existing in the prior art, thereby providing a lockable control shutter for an assembly line infrared receiver. ...
