[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] The embodiment of the present application discloses a photoelectric protection device for a punching machine, which is used to conveniently detect the working status of a sensor component.

[0035] Reference Figure 1 and Figure 2 A photoelectric protection device for a punching machine includes a body 1 and mounting frames 2 relatively distributed on both sides of the body 1. On one group of mounting frames 2, a plurality of groups of light-emitting elements 21 for emitting infrared light are sequentially installed at intervals along the height direction of the mounting frames 2, and on another group of mounting frames 2, a plurality of groups of light-receiving elements 22 for receiving infrared light are sequentially installed at intervals along the height direction of the mounting frames 2. In this embodiment, the light-emitting elements 21 and the light-receiving elements 22 are respectively arranged in a one-to-one correspondence, and the light-emitting device can use a high-brightness LED as a light source, and the light-receiving device uses a high-sensitivity photosensitive element, so that each group of light-receiving elements 22 receives the light emitted by the corresponding light-emitting element 21.

[0036] Reference Figure 2 and Figure 3A controller 23 and an alarm 24 are mounted on the mounting frame 2, and the light receiving element 22 and the alarm 24 are electrically connected to the controller 23. All the light receiving elements 22 are used to receive the light emitted by the corresponding light emitting element 21. If the light receiving element 22 receives the light emitted by the corresponding light emitting element 21, the light receiving element 22 that receives the light sends the light receiving data to the controller 23.

[0037] Reference Figure 2 and Figure 3 , the controller 23 can be specifically a single-chip microcomputer controller 23, and the controller 23 is used to receive the light receiving data sent by the light receiving element 22; in addition, the controller 23 has pre-stored reference light receiving information, and the reference light receiving information includes quantity information and identification information. The quantity information refers to the quantity data that should receive light, and the identification information is all identification codes of the light receiving element 22 that should receive light. The identification code is used to distinguish the codes of different light receiving elements 22. For example, the codes of the light receiving elements 22 are marked from top to bottom along the height direction of the mounting frame 2 as 001, 002... and so on. The light receiving data includes the quantity data of the light receiving element 22 that actually receives light and the identification code of the corresponding light receiving element 22.

[0038] Reference Figure 2 and Figure 3 The controller 23 is used to compare the quantity data in the light-receiving data with the quantity data in the reference light-receiving information when receiving the light-receiving data, and compare the corresponding identification code in the light-receiving data with all the identification codes in the reference light-receiving information. If the comparison is inconsistent, it is considered that it does not meet the working standards; otherwise, if the comparison is consistent, it is considered that it meets the working standards.

[0039] Reference Figure 2 and Figure 3 The controller 23 is used to control the alarm 24 to output a warning message when the working standard is not met. Specifically, the alarm 24 can be an alarm light that outputs the warning message by flashing the light, so that the detection personnel can be informed of the warning message.

[0040] Reference Figure 2 and Figure 3 The controller 23 includes an identification module 231 for receiving the light receiving data sent by the light receiving element 22 and identifying the identification codes of different light receiving elements 22 in the light receiving data. The identification module 231 compares the identification codes in the light receiving data with all the identification codes in the preset reference light receiving information one by one to determine the identification codes that exist in all the identification codes of the light receiving element 22 that should receive the light and do not exist in the received light receiving data.

[0041] Reference Figure 2 and Figure 3The controller 23 is electrically connected to the display 25, and the identification module 231 is used to identify the identification code (hereinafter referred to as the above code) that does not exist in the received light receiving data, send the above code to the display 25, and control the display 25 to output display information. Specifically, the display 25 can be a display screen, which outputs display information by displaying a coded image, so that the inspection personnel can know the coded information corresponding to the light-emitting component 21 at the fault location.

Specifically, the detection member 26 can be a high-sensitivity photosensitive element, which is used to detect whether the light-emitting member 21 emits infrared light that can be received by the light-receiving member 22. A light-emitting member 27 is slidably mounted on the mounting frame 2. Specifically, the light-emitting member 27 can use a high-brightness LED as a light source, which is used to detect whether the light-receiving member 22 receives light and emits light-receiving information. A moving component 3 is installed on the mounting frame 2 to drive the detection member 26 and the light-emitting member 27 to move along the arrangement direction of the light-emitting member 21.

[0043] Reference Figure 2 and Figure 3 The detection component 26 is electrically connected to the controller 23. When the detection component 26 receives the infrared light emitted by the light-emitting component 21, it sends out detection data, which means that the infrared light emitted by the corresponding light-emitting component 21 is received. The controller 23 is electrically connected to a light-emitting warning light 28. The controller 23 is used to determine whether the light-emitting component 21 meets the working standard when receiving the detection data, and control the light-emitting warning light 28 to output warning information. The specific light-emitting warning light 28 can be a warning light, which outputs warning information by emitting light, so that the detection personnel can know the warning information. On the contrary, if the light-emitting warning light 28 is not on, it means that the corresponding light-emitting component 21 is faulty.

[0044] Reference Figure 2 and Figure 3 The controller 23 is electrically connected to a light-receiving warning light 29. Specifically, the light-receiving warning light 29 can be a warning light, and the light-emitting warning light 28 and the light-receiving warning light 29 can emit light of different colors to output warning information by emitting light.

[0045] Reference Figure 2 and Figure 3 After the light emitting element 27 emits infrared detection light that can be received by the light receiving element 22, when the corresponding light receiving element 22 receives the detection light emitted by the light emitting element 27, the light receiving element 22 emits light measurement data; the controller 23 is used to receive the light measurement data, and when receiving the light measurement data, the controller 23 is used to determine that the light receiving element 22 meets the working standard, and control the light receiving warning light 29 to emit light that can be known by the inspection personnel. On the contrary, if the light receiving warning light 29 is not on, it means that the corresponding light receiving element 22 is faulty.
