Description

Technical Field

[0001] This utility model relates to the field of photoelectric reflective proximity switch technology, and more specifically, it relates to a photoelectric reflective proximity switch. Background Technology

[0002] A photoelectric reflective proximity switch is a sensor that detects the presence or absence of an object by utilizing the blocking or reflection of a light beam by the detected object, with a synchronous circuit connecting the circuit. Its working principle is that the photoelectric switch converts the input current into a light signal at the transmitter, and the receiver then detects the target object based on the intensity or presence of the received light. The object is not limited to metal; any object that can reflect light can be detected. Photoelectric switches have advantages such as small size, multiple functions, long lifespan, high precision, fast response speed, long detection distance, and strong resistance to light, electrical, and magnetic interference. They are widely used in various applications, such as level detection, liquid level control, product counting, width discrimination, speed detection, fixed-length shearing, hole identification, signal delay, automatic door sensing, color mark detection, punch presses and shearing machines, and safety protection.

[0003] However, most existing photoelectric reflective proximity switches have cumbersome disassembly and assembly procedures, and after installation, it is inconvenient to make corresponding adjustments according to the actual situation, which affects the flexibility of detection.

Through the operation of the drive assembly 12, the second threaded rod 13 can be rotated, thereby moving the second threaded sleeve 15, the adjustment mounting plate 10, and the switch body 11, facilitating adjustments to the installed switch body 11 according to actual needs, thus assisting in detection work. The fixed frame 2 has a first threaded sleeve 6 inside, and a first threaded rod 7 is threadedly connected inside the first threaded sleeve 6. A first rotating shaft 8 is welded to the bottom end of the first threaded rod 7. The first rotating shaft 8 is sleeved with a clamping mounting plate 3 through a bearing B. By rotating the first threaded rod 7, the first threaded rod 7, the first rotating shaft 8 and the clamping mounting plate 3 are driven to rise and fall with the help of the first threaded sleeve 6. This can assist in clamping at a suitable installation position and ensure the stability of the structure. The clamping mounting plate 3 has an installation hole 4 inside. By setting the installation hole 4, further installation and reinforcement can be carried out to further ensure the stability of processing during operation. A limit component 5 is set between the clamping mounting plate 3 and the fixed frame 2. By setting the limit component 5, the clamping mounting plate 3 can be limited and supported, ensuring the stability of the clamping mounting plate 3 when adjusting and moving.

[0029] Specifically, the drive assembly 12 includes a motor frame 121, which is disposed on one side of the support frame 1. A drive motor 122 is disposed inside the motor frame 121.
