Embodiment

[0038] The working steps of the light curtain sensor of the present invention are as follows:

[0039] 1. Start the assembly line, the power input of the assembly line and the power input of the light curtain sensor are uniformly configured;

[0040] 2. The product needs to be placed on a dedicated placement module, and the placement module has a fixed placement position;

[0041] 3. When the product and the placement module pass through the light curtain sensor, the LED light of the light projector shines on the product, and the product blocks the light. At this time, the detection module and the detection module in the light curtain sensor start at the same time;

[0042] 4. The detection module detects the outer size of the product, the detection module detects the size of each part of the product, and compares the detection data with the set data through processing. The qualified size passes through the light curtain sensor; the unqualified product is pushed by the push ro...

Abstract

The invention discloses a light curtain sensor. A detection module is arranged on the light curtain sensor. While a product is detected through the light curtain sensor, the detection module detects the product through an infrared lamp at the same time; if the product is qualified, the product passes through the n-shaped light curtain sensor; and if the product is not qualified, the detection module can give an instruction to a motor, the motor drives a gear shaft rod to rotate, the gear shaft rod drives a push plate to move forwards, the push plate rapidly pushes the product out of an assembly line and pushes the product to an unqualified product collection bin, the unqualified product collection bin leads the unqualified product into an unqualified product temporary storage box, and after one action is completed, the push plate is reversely driven by the gear shaft rod to retreat into a slide box. The light curtain sensor can detect the size of the product and can also detect whether the product is qualified or not according to the size.

Description

technical field [0001] The invention relates to the technical field of LED lighting applications, in particular to a light curtain sensor. Background technique [0002] Light curtain sensors are widely used in mechanical protection devices and are often called safety light curtains. They are widely used in modern factories, where people and machines work together, on some potentially dangerous mechanical equipment, such as stamping machinery, shearing equipment , metal cutting equipment, automated assembly line, automated welding line, mechanical transmission and handling equipment, and dangerous areas are likely to cause personal injury to operators, so light curtain sensors will be installed to avoid the possibility of personal injury to operators. In addition to factories, it may also be used in the field of hotel automatic doors. [0003] But this is only for the prevention of danger, but it does not have the detection function for the product. Therefore, the traditiona...
