[0022] To better explain and facilitate understanding of this utility model, the technical solution and effects of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1As shown, a waste alloy material sorting device based on LIBS technology includes a conveying system, which in this embodiment includes a conveyor belt 2. The end of the conveyor belt 2 includes multiple parallel transport channels corresponding to different alloy categories, used for transporting the sorted materials. In this embodiment, these include a stainless steel channel 10, an aluminum alloy channel 11, and a copper alloy channel 12.

[0024] The conveying system is equipped with a cleaning system 3, a LIBS detection system and a sorting system in sequence along the conveying path, and the sorting system is electrically connected to the LIBS detection system.

[0025] The cleaning system 3 is located in the initial conveying section, and the cleaning end is located above the cleaning system 3. It is used for surface cleaning of the waste alloy material 1 to prepare for subsequent accurate testing. The cleaning system 3 is one or a combination of several of the following: an air jet cleaning device, a brush cleaning device, or a liquid spray cleaning device. For example, a commercially available rolling brush or water gun can be used to clean the surface of the waste alloy material 1.

[0026] The LIBS detection system is located downstream of the cleaning system 3 on the conveyor belt 2 and is used for identifying waste alloy material 1. Specifically, it includes a LIBS laser 4, a fiber optic sensor 5, a spectrometer 8, and a computer 9. The LIBS laser 4 and fiber optic sensor 5 are symmetrically arranged on both sides of the conveyor system. The fiber optic sensor 5 receives plasma emission information at a 45-degree angle to the laser emitted by the laser. Specifically, the LIBS laser 4 is a pulsed laser located on one side of the conveyor system, used to emit a laser beam with a wavelength of 1064 nm, which acts on the surface of the passing waste alloy material 1, exciting and generating plasma. The fiber optic sensor 5 is used to collect the spectral signal emitted by the plasma. The spectrometer 8 is electrically connected to the fiber optic sensor 5 and is used to receive and analyze the spectral signal collected by the fiber optic sensor 5. The computer 9 is connected to the spectrometer 8 and is used to receive the spectral data transmitted by the spectrometer 8, perform qualitative analysis, identify the category of waste alloy material 1, and issue corresponding working instructions to the classification system.

[0027] Furthermore, a gravity sensor (not shown in the figure) is installed on the conveying system at a position corresponding to the cleaning system 3, and is electrically connected to the computer 9.

[0028] The sorting system is located downstream of the end of the conveyor belt 2 and is electrically connected to the computer 9. It is used to sort the identified materials and transport the waste alloy material 1 to the corresponding channel. Specifically, it includes a robotic arm 6 and a sorting execution mechanism 7 connected to the robotic arm 6. The sorting execution mechanism 7 is one of a mechanical push rod, a flip plate, a diversion chute, or a multi-channel sorting robot, connected to the execution end of the robotic arm 6. According to different instructions from the computer 9, it sorts the waste alloy material 1 to the corresponding transmission channel. The correspondence between the sorting execution mechanism 7 and different transmission channels is pre-set in the computer 9. Specifically, when the sorting execution mechanism 7 uses a mechanical push rod, the robotic arm 6 drives the mechanical push rod to move and push the waste alloy material 1 to the transmission channel corresponding to its category; when the sorting execution mechanism 7 uses a flip plate or diversion chute, the robotic arm 6 drives the flip plate or diversion chute to move to the transmission channel, changing the original conveying direction of the waste alloy material 1 and making it move towards the transmission channel corresponding to its category; when the sorting execution mechanism 7 uses a multi-channel sorting robot, the robotic arm 6 drives the multi-channel sorting robot to move and move the waste alloy material 1 to the transmission channel corresponding to its category.

[0029] A gravity sensor (not shown in the figure) is installed at a position on the conveying system corresponding to the classification system, and is electrically connected to the computer 9.

[0030] The process of classifying waste alloy material 1 using the above-mentioned LIBS-based waste alloy material classification device is as follows:

[0031] Waste alloy material 1 is placed at the starting conveyor end of conveyor belt 2 and conveyed forward. Conveyor belt 2 is used to carry waste alloy material 1 and transport waste alloy material 1 at a fixed speed.

[0032] Waste alloy material 1 is transferred to cleaning system 3. Gravity sensor detects the signal change and sends the signal to computer 9. Computer 9 issues a working command to cleaning system 3 based on the increased gravity signal, and starts cleaning system 3 to clean the surface of waste alloy material 1. When waste alloy material 1 leaves the cleaning area, computer 9 issues a stop working command to cleaning system 3 based on the decreased gravity signal sent by gravity sensor. Cleaning system 3 stops working, completing the surface cleaning of waste alloy material 1.

[0033] LIBS laser 4 emits a 1064nm wavelength laser to excite plasma luminescence on the surface of waste alloy material 1. Fiber optic sensor 5 receives the plasma luminescence information and transmits it to spectrometer 8. Spectrometer 8 receives and analyzes the spectral information and transmits the spectral information to computer 9.

[0034] Computer 9 receives spectral data and performs qualitative analysis to identify the category of waste alloy material 1, and issues corresponding work instructions to the classification system according to the category;

[0035] The sorting system receives information from computer 9. When waste alloy material 1 is transferred to the sorting system, the gravity sensor detects a signal change and sends the signal to computer 9. Computer 9 issues a working command to the sorting system based on the increased gravity signal, activating the sorting system. According to the working command, the robotic arm 6 drives the sorting execution mechanism 7 to move the waste alloy material 1, moving it to the corresponding transmission channel according to its category. Once the waste alloy material 1 is sorted into the corresponding transmission channel, the sorting system returns to its original position, and then the corresponding transmission channel continues to transfer the waste alloy material 1. Specifically, the robotic arm 6 moves according to the command of computer 9, driving the sorting execution mechanism 7 to send the waste alloy material 1 to the corresponding stainless steel channel 10, copper alloy channel 12, or aluminum alloy channel 11 to complete the sorting. Specifically, taking aluminum alloy as an example of waste alloy material 1, when the sorting execution mechanism 7 uses a mechanical push rod, the robotic arm 6 drives the mechanical push rod to move, pushing the waste alloy material 1 onto the aluminum alloy channel 11 corresponding to the aluminum alloy material; when the sorting execution mechanism 7 uses a flap or diversion chute, the robotic arm 6 drives the flap or diversion chute to move onto the transmission channel, changing the original transmission direction of the waste alloy material 1, causing it to move towards the aluminum alloy channel 11; when the sorting execution mechanism 7 uses a multi-channel sorting robot, the robotic arm 6 drives the multi-channel sorting robot to move, moving the waste alloy material 1 onto the aluminum alloy channel 11. In this embodiment, taking aluminum alloy as an example, the sorting execution mechanism 7 uses a mechanical push rod. When the waste alloy material 1 is identified as aluminum alloy, the mechanical push rod is driven forward by the robotic arm 6, pushing the aluminum alloy onto the aluminum alloy channel 11, as shown below. Figure 2 As shown, continue conveying forward.
