[0002] In the prior art, many devices are equipped with photoelectric protection devices to protect the operation of the devices. Generally, a light sensor is used to detect whether the operator's body leaves the dangerous area. If it is detected that the hands and other parts do not leave the dangerous area, the machine does not work. Only when any part of the operator's body leaves the dangerous area, the machine works.
[0003] At present, the existing photoelectric protection devices have relatively simple working contents and only monitor one task, resulting in the installation of multiple photoelectric protection devices on some important devices to monitor different parts, which not only increases the cost, but also is troublesome to operate and occupies space. Secondly, dust will accumulate on the photoelectric devices during the working process, thus affecting their sensitivity. Content of the Utility Model
[0004] The purpose of the utility model is to solve the defects existing in the prior art, and to provide an opposed photoelectric protection device.

The opposed photoelectric element includes two groups of opposed photoelectric transmitters and two groups of opposed photoelectric receivers. Control the two opposed photoelectric transmitters and the opposed photoelectric receivers to rotate to the first position to complete the photoelectric monitoring of the front and rear sides of the processing area, and control the two opposed photoelectric transmitters and the opposed photoelectric receivers to rotate to the second position to complete the photoelectric monitoring of the left and right sides of the processing area.
[0007] Preferably, the two opposed photoelectric transmitters and the two opposed photoelectric receivers are both electrically connected to a central controller and a counter.

DETAILED DESCRIPTION OF THE INVENTION
[0020] In order to make the above - mentioned objects, features and advantages of the present utility model more obvious and understandable, the following will describe the specific embodiments of the present utility model in detail with reference to the drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.
[0021] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation.
[0022] Referring to the attached Figure 1 - attached Figure 5 , an opposed - type photoelectric protection device, comprising a support column 3 and an opposed - type photoelectric device 4. The opposed - type photoelectric device 4 is composed of a frame 411, a cleaning device 413 and opposed - type photoelectric elements 412. The frame 411 is provided with side openings 414 on multiple sides. The opposed - type photoelectric elements 412 are rotatably placed in the frame 411, and an optoelectronic receiving and transmitting surface 415 is provided thereon. The optoelectronic receiving and transmitting surface 415 emits or receives light through the side openings 414, thereby realizing detection at different angles. The cleaning device 413 is arranged between two adjacent side openings 414, and the optoelectronic receiving and transmitting surface 415 will pass through the cleaning device 413 during rotation, so as to be effectively cleaned.
[0023] The frame 411 here is of a square structure, and side openings 414 are provided on all four sides, which can not only emit and receive light but also play a role in heat dissipation.
[0024] The opposed - type photoelectric device 4 here is divided into an opposed - type photoelectric transmitter 401 and an opposed - type photoelectric receiver 402. Both the opposed - type photoelectric transmitter 401 and the opposed - type photoelectric receiver 402 are electrically connected to a central controller and a counter. The opposed - type photoelectric transmitter 401 emits light, and the opposed - type photoelectric receiver 402 controls the processing area 2 according to whether it receives the light. The counter can count the products in the conveying direction.
[0025] Among them, the cleaning device 413 is preferably a blowing device. When the photoelectric receiving and emitting surface 415 rotates to the side opening 414, the detection end of the opposed photoelectric element 412 can be abutted against the cleaning device 413, playing the role of a valve and being able to prevent the blown gas. When rotating, there is a certain gap between the photoelectric receiving and emitting surface 415 and the cleaning device 413. At this time, it is equivalent to the gas valve being opened, and the gas can be blown out. By rotating the opposed photoelectric element 412, the control of the gas can be realized, and then the photoelectric receiving and emitting surface 415 can be cleaned to prevent dust from affecting the sensitivity of the opposed photoelectric device 4.
[0026] In addition, two sets of sealing components arranged along the vertical direction are fixed on the outer wall of the opposed photoelectric element 412. The sealing components include two sealing strips arranged at intervals. The distance between the two sealing strips is adapted to the width of the cleaning device 413, and can play a good sealing role for the cleaning device 413 during the monitoring stage.
[0027] It also needs to be explained here that an electric control rotating element is installed at the bottom of the frame 411 to control the opposed photoelectric element 412 to rotate a predetermined angle, preferably 90°, which simplifies the control operation procedure.
[0028] When the present utility model is in use, through the above structural design, the opposed photoelectric transmitter 401 and the opposed photoelectric receiver 402 can be respectively and oppositely arranged around the processing area 2. When the processing area 2 is working, the photoelectric receiving and emitting surfaces 415 of the opposed photoelectric transmitter 401 and the opposed photoelectric receiver 402 rotate to the operation area 5 to monitor the operation areas 5 on the front and rear sides of the processing area 2 to prevent personnel from entering by mistake. When the processing area 2 stops working, the photoelectric receiving and emitting surfaces 415 of the opposed photoelectric transmitter 401 and the opposed photoelectric receiver 402 rotate to the assembly line 1 to monitor the products on the assembly line 1 on the left and right sides of the processing area 2. The two-way monitoring not only saves costs but also greatly reduces the space occupation.
[0029] Finally, it needs to be explained that Figure 2 and Figure 3 the direction of the arrow in the figure is the schematic direction of laser emission.
[0030] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
