Double-sided dual-receiver array light curtain

Abstract

The invention discloses a two-sided dual receiver array light curtain. By arranging two receiver arrays on each side of the opposite sides of a frame structure, an entire optical detection coordinateplane is formed, the phenomenon that a receiver array needs to be arranged in a beveled mode or two adjacent receiver arrays which are arranged in a staggered mode front and back are in lap joint andare coupled can be avoided, independent sealing of each side is facilitated, thus, the scoring accuracy and scoring reliability are improved advantageously, and liable faults during application and maintenance are reduced. The light curtain is characterized in that the light curtain comprises the frame structure; a first receiver array and a second receiver array are arranged on the left side portion of the frame structure; a third receiver array and a fourth receiver array are arranged on the right side portion of the frame structure; a first transmitter is arranged at the lower corner of theright side of the frame structure; a second transmitter is arranged at the upper corner of the right side of the frame structure; a third transmitter is arranged at the lower corner of the left sideof the frame structure; and a fourth transmitter is arranged at the upper corner of the left side of the frame structure.

Description

technical field [0001] The present invention relates to the technology of electronic target light curtain, especially a double-sided double-receiver array light curtain. Two receiver arrays are arranged on each side of a frame structure to form the entire optical detection coordinate plane. It can avoid the phenomenon that a receiver array needs to be set at a knuckle or the overlapping coupling phenomenon of two adjacent receiver arrays that are misaligned front and back, so that each side can be independently sealed, and cross joint sealing is no longer required, which reduces the installation cost. The process is difficult, which is conducive to improving the accuracy and reliability of target reporting, and reducing the possible failures in use and maintenance. Background technique [0002] The light curtain electronic target generally forms a quadrilateral optical detection coordinate plane through two transmitters and two receiver arrays. The emission angles of the two...

Problems solved by technology

The inventors found that the sealing of the optical path at the knuckle structure is difficult to achieve, and the knuckle sealing structure may cause interference to the reception of the 45-degree diagonal optical path, increasing the difficulty of installation and maintenance. hard to guarantee
