[0029] Compared with traditional mechanical protection equipment, photoelectric protection equipment is simpler to set up, does not require controlling the mechanical protection equipment to change position for protection, has more monitoring functions, and better monitoring effect. However, due to the working principle of photoelectric protection equipment, multiple sets of photoelectric protection equipment need to be set up when monitoring different areas, which increases the monitoring cost and the cost of later maintenance. Its internal control system is more complicated, and its monitoring status is difficult to switch quickly according to the needs of the production line.

[0030] In order to solve the above problems, refer to the attached Figure 1 -attached Figure 8 , the improved method of processing workshop safety protection system, comprising the following steps:

[0031] S1, according to the conveying line 100 and the processing chamber 200 to determine the safety area, the photoelectric protection equipment 400 is arranged outside the safety area; the photoelectric protection equipment 400 includes two groups of center symmetrically arranged photoelectric protection devices, the photoelectric protection device includes the photoelectric emission equipment 4001 and the photoelectric receiving equipment 4002 arranged at intervals; the photoelectric emission equipment 4001 can emit detection laser towards the photoelectric receiving equipment 4002, and the transmission state of the detection laser can be used to judge whether someone misenters the processing area or realizes the counting of the conveying product on the surface of the conveying line 100.

[0032] S2, rotate the photoelectric receiving equipment 4002 opposite to the two photoelectric emission equipment 4001 on the opposite side of the conveying line 100, complete the photoelectric monitoring of the surface of the conveying line 100; can refer to the attached Figure 2 At this time, the photoelectric emission equipment 4001 and the photoelectric receiving equipment 4002 are used to monitor the product conveyed on the surface of the conveying line 100, the product on the surface of the conveying line 100 can be counted, or the conveying state of the product on the surface of the conveying line 100 is judged, and the related data is fed back to the central system, so as to judge whether the conveying line 100 is in normal conveying state.

[0033] S3, rotate the photoelectric receiving equipment 4002 opposite to the two photoelectric emission equipment 4001 on the same side of the conveying line 100, complete the photoelectric monitoring of the two sides of the conveying line 100, can refer to the attached Figure 3 At this time, the photoelectric emission equipment 4001 and the photoelectric receiving equipment 4002 can monitor the area of the processing window 300 on the two sides of the processing chamber 200, which can avoid the misentry of the staff into the processing area and avoid the occurrence of unexpected production.

[0034] In summary, through the above structure design, the two groups of center symmetrically arranged photoelectric protection devices can complete the monitoring protection in four directions, and the two groups of photoelectric protection devices can quickly adjust the monitoring range and state according to the processing requirement, so as to meet the production requirement in different processing workshops; through the above improved scheme, the cost of the early stage of workshop safety protection and the cost of later maintenance are greatly reduced, the operation is simple, and the monitoring state can be quickly switched according to the production requirement.

[0035] It should be noted that a plurality of rotatable photoelectric protection devices 400 can be arranged at different height positions outside the processing chamber 200, which can respectively realize adaptive monitoring of the waist and feet of the workers or products of different sizes or different types of conveying lines 100; or simultaneously monitor in the same direction or different directions, meeting the diversified safety protection requirements.

[0043] After the two photoelectric emission devices 4001 are arranged, they are fixed to the ground, and then the two photoelectric emission devices 4001 are rotated to emit positioning laser towards the first side, two positioning lasers intersect to form a first positioning point, a first photoelectric receiving device 4002 is installed according to the first positioning point, and the first photoelectric receiving device 4002 can be located at the first positioning point to receive the laser emitted from both sides; the two photoelectric emission devices 4001 are rotated to emit positioning laser towards the second side, two positioning lasers intersect to form a second positioning point, a second photoelectric receiving device 4002 is installed according to the second positioning point, and the second photoelectric receiving device 4002 can be located at the second positioning point to receive the laser emitted from both sides.
