Problems solved by technology

On the one hand, the efficiency of manual sorting is low; on the other hand, after working for a period of time, manual sorting will easily cause visual fatigue, which will easily increase the missed detection rate, which is not conducive to the smooth progress of silicon material sorting.

Embodiment 1

[0054] figure 1 with Figure 3-Figure 5 It is a schematic structural diagram of a silicon material sorting system based on machine vision according to an embodiment of the present invention.

[0055] see figure 1 with Figure 3-5 As shown, the silicon material sorting system based on machine vision includes a first conveying device 2, a control system, and a feeding device 1 for paving and loading materials. The feeding device 1 is used in cooperation with the conveying start end of the first conveying device 2 for feeding materials to the conveying start end of the first conveying device 2 . The first conveying device 2 is equipped with a first machine vision image acquisition device 4 for real-time acquisition of the RGB images of the silicon material to be sorted conveyed by the first conveying device 2, and a first machine vision image acquisition device 4 for sucking the first conveying device 2 The first abnormal material sorting device 3 for the abnormal material am...

Embodiment 2

[0081] Figure 2-Figure 4 with Image 6 It is another embodiment of the machine vision-based silicon material sorting system of the present invention.

[0082] see Figure 2-Figure 4 with Image 6 , compared with the silicon material sorting system based on machine vision described in Embodiment 1, the silicon material sorting system based on machine vision described in this embodiment is different in that: the The silicon material sorting system based on machine vision also includes a second conveying device 2' arranged below the first conveying device 2, and an arc-shaped reversing plate used in conjunction with the second conveying device 2' and the first conveying device 2 6. Described second conveying device 2 ' also adopts belt conveyor. The second conveying device 2' is equipped with a second machine vision image acquisition device 4' and a second abnormal material sorting device 3'. The second machine vision image acquisition device 4' is used to collect in real ...

Abstract

The invention provides a silicon material sorting system based on machine vision. The silicon material sorting system comprises a first conveying device, a control system and a feeding device for leveling and feeding; and the first conveying device is provided with a first machine vision image acquisition device for real-time acquisition of RGB images of to-be-sorted silicon materials conveyed bythe first conveying device, and a first abnormal material sorting device for absorbing abnormal materials in the to-be-sorted silicon materials conveyed on the first conveying device are arranged on the first conveying device. The silicon material sorting system further comprises a second conveying device and an arc-shaped reversing plate for being used in fit with the second conveying device andthe first conveying device; and a second machine vision image acquisition device and a second abnormal material sorting device which are successively distributed in the conveying direction of the second conveying device are arranged on the second conveying device. The silicon material sorting system based on machine vision is used for improving the efficiency of silicon material sorting and decreasing the probability of leak detection of silicon material sorting.

Description

technical field [0001] The invention relates to the field of silicon material sorting, in particular to a machine vision-based silicon material sorting system, which is mainly used for sorting abnormal materials in silicon material. Background technique [0002] In the photovoltaic industry, silicon materials are divided into flakes and blocks. The diameter of the flakes ranges from 1mm to 15mm, and the diameter of the blocks ranges from 3mm to 15mm. Silicon material is a commonly used material in the production process of the photovoltaic industry, such as using silicon material for polycrystalline silicon ingots. [0003] Before silicon materials are used, for example, before they are used in polysilicon ingots, corresponding preparations need to be carried out, that is, the silicon materials need to be cleaned, sorted, sorted and other processes. [0004] Among them, the sorting of silicon materials mainly includes foreign matter sorting and abnormal material sorting. A...
