Problems solved by technology

However, in the traditional light test process, it is necessary to manually block the infrared rays emitted by the light curtain emitter while observing whether the shading signal light of the safety light curtain is normally lit. This operation method is cumbersome and affects the test efficiency. Therefore, there is still room for improvement

Abstract

The invention discloses a light curtain automatic test device, which belongs to the technical field of light curtain sensors. The key points of the technical solution include a relatively arranged emitting installation bracket and a receiving installation bracket. A light curtain emitter is arranged on the emission installation bracket. A light curtain receiver is arranged on the receiving installation bracket, and a guide rail parallel to the length direction of the light curtain emitter is arranged under the emission installation bracket, and a light curtain shading assembly and a light curtain shading assembly for driving The driving mechanism for reciprocating movement of the light curtain shading assembly along the length direction of the guide rail, and a judgment module and The shading signal lamp is electrically connected with the judging module and used to receive judging signals. The invention can facilitate the staff to test the safety light curtain and improve the testing efficiency.

Description

Technical field[0001]The invention belongs to the technical field of light curtain sensors, and more specifically it relates to a light curtain automatic test device.Background technique[0002]The safety light curtain is mainly composed of a light curtain emitter and a light curtain receiver. The light curtain emitter emits infrared rays or laser light, and the photosensitive unit of the light curtain receiver receives the infrared rays or laser light to form a gap between the light curtain emitter and the light curtain receiver Protect the light curtain. When the light curtain is blocked, the device sends out a light blocking signal to control potentially dangerous mechanical equipment to stop working and avoid safety accidents.[0003]At present, after the safety light curtain leaves the factory, it is generally necessary to perform a light test on the safety light curtain to ensure that the laser light emitted by the light curtain transmitter accurately acts on the photosensitive un...
