Detailed Description
In order to make the technical problems, technical schemes and beneficial effects to be solved more clear, the invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention. It will be understood that when an element is referred to as being "mounted" or "disposed" on another element, it can be directly on the other element or be indirectly on the other element. When an element is referred to as being "mounted" on another element, it can be directly or indirectly connected to the other element. It is to be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are merely for convenience in describing and simplifying the description based on the orientation or positional relationship shown in the drawings, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus are not to be construed as limiting the invention. Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the invention, "a number" means one or more than one; the meaning of "a plurality of" is two or more, unless specifically defined otherwise. The "fixed connection" may be a bolted connection, welded, interference fit, integrally formed, or the like, as is known in the art. As long as the fixed connection can be realized, the corresponding components can normally function.
The detection device consists of a shading fixing plate, a shading moving plate, a photoelectric switch, an electromagnetic reciprocating rod reset spring, an electromagnetic reciprocating rod, an electromagnetic reciprocating coil, a detection device base and a shading fixing plate bracket.
The detection device base is used for fixing the electromagnetic reciprocating coil and the shading fixing plate support. An electromagnetic reciprocating rod is arranged in the center of the electromagnetic reciprocating coil, and can realize rapid reciprocating motion along the axial direction under the condition that the electromagnetic reciprocating coil is powered on or powered off, and a reset spring is arranged at one end of the electromagnetic reciprocating rod, so that the reciprocating rod can be stopped to a set position. The other end of the electromagnetic reciprocating rod is provided with a shading movable plate. The shading fixing plate bracket is provided with the shading fixing plate, and detection of the photoelectric protection devices with different optical axis intervals can be realized by replacing the shading fixing plates with different widths. The shading fixed plate and the shading movable plate are parallel to each other, two symmetrical small holes are respectively formed in the shading fixed plate and the shading movable plate, and when the electromagnetic reciprocating rod is reset (the electromagnetic reciprocating coil is powered off), the small holes in the two plates are overlapped, and the two symmetrical small holes can be used for transmitting light. When the electromagnetic reciprocating rod acts (the electromagnetic reciprocating coil is electrified), the small holes on the two plates are not overlapped, and the two symmetrical small holes are simultaneously in a shading state. The lower symmetrical small hole is used for shading and transmitting light beams emitted by the photoelectric switch, and the upper symmetrical small hole is used for shading and transmitting any light beam emitted by the photoelectric protection device. The photoelectric switch has smaller response time (about 0.2ms is generally used in the market), and errors caused by the response time of the photoelectric switch can be ignored when the response time of the photoelectric protection device is detected. When the electromagnetic reciprocating coil is electrified, the electromagnetic reciprocating rod drives the shading movable plate to shade the photoelectric switch and the photoelectric protection device simultaneously, the photoelectric switch and the photoelectric protection device can send respective level signals successively, the time difference between the two level signals is the corresponding time of the photoelectric protection device, and the time difference between the two level signals can be acquired by the oscilloscope.
