[ detailed description ] A

Referring to the attached drawings 1 and 2 of the specification, the present invention is a yarn sensor opened or closed by induction, which is composed of a casing 1, a cover plate 2, a light-transmitting seat 3, a PCB 4, a first photoelectric sensor 5, a second photoelectric sensor 6, an infrared induction switch 7, and so on.

The cover plate 2 covers the housing 1, so that a mounting cavity 10 is formed between the cover plate and the housing 1, and electronic components such as the PCB 4, the first photoelectric sensor 5, the second photoelectric sensor 6 and the infrared inductive switch 7 are contained in the mounting cavity 10. In the embodiment, the peripheries of the shell 1 and the cover plate 2 are bonded together through glue, so that the mounting cavity 10 is sealed, the sealing performance of the sealing mode is good, and the service life of the sensor is prolonged.

The light-transmitting seat 3 is mounted on the housing 1 and has an opening 31 at one side thereof to facilitate the penetration of the yarn into the light-transmitting seat 3. The light-transmitting seat 3 is of a hollow cylindrical structure, so that the light-transmitting seat 3 can be in smooth contact with yarns, and the yarns are prevented from being abraded.

The PCB board 4 is installed in the installation cavity 10. The first photoelectric sensor 5, the second photoelectric sensor 6 and the infrared induction switch 7 are electrically connected to the PCB respectively, and signals are processed through the PCB 4. The PCB 4 is a prior art PCB and will not be described herein. A sealing plug 11 is embedded at the rear end of the housing 1, and the lead 9 passes through the sealing plug 11 and is electrically connected with the PCB 4, thereby outputting a corresponding signal of the sensor. Due to the arrangement of the sealing plug 11, the sealing performance of the installation cavity 10 is better.

The first photoelectric sensor 5 and the second photoelectric sensor 6 are positioned on two sides of the light-transmitting seat 3, and if the two sensors can simultaneously sense that yarns exist in the light-transmitting seat 3, the yarn production equipment can work normally; if only one sensor can sense the existence of the yarns in the light-transmitting seat 3 or both sensors cannot sense the existence of the yarns in the light-transmitting seat 3, the yarn production equipment stops working. In the present embodiment, the first photo sensor 5 and the second photo sensor 6 form an included angle of 120 °, so that the sensing ranges of the two sensors in the light-transmitting seat 3 are large.

The infrared inductive switch 7 is positioned at one side of the front end in the shell 1. Specifically, a pair of mounting arms 12 is provided at the front end of the housing 1, and a finger passage 13 is provided between the mounting arms 12. The finger channel 13 communicates with the opening 31.
