Description

Technical Field

[0001] This utility model belongs to the technical field of workpiece quality inspection, specifically relating to a vision sorting machine for classifying and collecting NG materials. Background Technology

[0002] Vision sorting machines are advanced devices that use machine vision technology to accurately identify and analyze the appearance features of products, thereby achieving automatic product classification and screening. In their workflow, the effective collection of detected defective (NG) materials is crucial for subsequent production management and quality control. Existing vision sorting machines generate a large amount of NG materials during long inspection periods, a significant portion of which only have minor surface scratches. Considering their internal structure and overall performance parameters, these materials still have the potential to be transformed into qualified products through appropriate rework. For example, in the vision sorting of precision metal parts, some parts may have only minor surface scratches due to slight friction during production, but their dimensional accuracy, material properties, and other key elements still meet requirements. If these scratches are ground or polished, they can be restored to qualified standards. However, most existing vision sorting machines collect NG materials and discard them, undoubtedly causing significant waste. Those NG materials that could be repaired through rework are not effectively utilized, increasing production costs and reducing raw material utilization, which is detrimental to sustainable development and optimal resource allocation. Utility Model Content

[0003] The purpose of this invention is to provide a vision sorting machine for classifying and collecting non-compliant materials, thereby solving the aforementioned technical problems.

[0004] This utility model is achieved through the following technical solution: a visual sorting machine for classifying and collecting NG materials, including a feeding component, a detection component, several NG material collection components that can independently discharge materials corresponding to different defects, and a good material collection component. The detection component is connected to the feeding component. The NG material collection component and the good material collection component are located at the discharge end of the detection component. The detection component includes a turntable and several CCD detection mechanisms arranged sequentially on the turntable. The good material collection component includes a first pneumatic blowing component installed on the turntable, a first guide chute connected to the first pneumatic blowing component, and a first collection frame docking at the discharge end of the first guide chute. The several NG material collection components include several second pneumatic blowing components that can independently blow materials corresponding to different defects, second guide chute connected to the second pneumatic blowing components, and several second collection frames docking at the discharge end of the second guide chute. The first collection frame and the several second collection frames are arranged side by side on the outside of the turntable.

[0005] Furthermore, both the first and second guide chutes are covered with baffle plates, which extend to the discharge end above the first and second collection frames.

[0006] Furthermore, partitions are provided between the first and second aggregate frames, as well as between adjacent second aggregate frames.

[0007] Furthermore, the feeding assembly includes a vibratory plate and a flat vibrating mechanism, wherein the flat vibrating mechanism is connected between the discharge end of the vibratory plate and the feed end of the turntable.

[0008] Furthermore, an automatic feeding bin is provided on the side of the vibratory plate away from the flat vibration mechanism, and the discharge end of the automatic feeding bin is provided with a sensing mechanism for detecting the remaining material in the vibratory plate.

[0016] The present invention will be further illustrated below with reference to specific examples and accompanying drawings.

[0017] like Figure 1-Figure 2 As shown, this utility model describes a vision sorting machine for classifying and collecting defective (NG) materials. It includes a feeding assembly 1, a sorting assembly 2, several NG material collection assemblies 3 that can independently discharge materials corresponding to different defects, and a good material collection assembly 4. The sorting assembly 2 is connected to the feeding assembly 1. The NG material collection assemblies 3 and the good material collection assembly 4 are located at the discharge end of the sorting assembly 2. The sorting assembly 2 includes a turntable 21 and several CCD detection mechanisms 22 arranged sequentially on the turntable 21. The good material collection assembly 4 includes components mounted on the turntable 21. The first pneumatic blowing element 41 on the turntable 21, the first guide chute 42 connected to the first pneumatic blowing element 41, and the first collection frame 43 docking at the discharge end of the first guide chute 42 are included. The plurality of NG material collection components 3 include a plurality of second pneumatic blowing elements 31 that blow material independently corresponding to different defects, a second guide chute 32 connected to the second pneumatic blowing element 31, and a plurality of second collection frames 33 docking at the discharge end of the second guide chute 32. The first collection frame 43 and the plurality of second collection frames 33 are arranged side by side on the outside of the turntable 21.

[0018] In use, the material is conveyed to the turntable 21 of the inspection component 2 through the feeding component 1. The turntable 21 rotates at a constant speed, causing the material to pass through several CCD inspection mechanisms 22 in sequence. The CCD inspection mechanism 22 performs comprehensive inspection of the material, obtaining information on the material's appearance, size, color, and other aspects, and compares it with preset standards. If the material is determined to be good, when the material moves to the position of the corresponding first pneumatic blowing element 41, the first pneumatic blowing element 41 is activated under the action of the control system (usually controlled by a solenoid valve), blowing the good material into the first guide chute 42, and then sliding along the chute into the first collection frame 43. If the material is determined to be NG material, according to its defect type, the corresponding second pneumatic blowing element 31 is activated, blowing the NG material into the corresponding second guide chute 32, and finally falling into the corresponding second collection frame 33.

[0019] This invention can accurately classify and collect NG materials according to different defects, while effectively separating good materials. By accurately distinguishing NG material types, this vision sorting machine avoids the uniform scrapping of materials that can be reworked and repaired. NG materials that can be reprocessed can be sent back to the appropriate stage of the production process for repair in a timely manner, reducing the waste of raw materials and thus achieving optimized resource utilization. It also reduces raw material waste and cost increases. Moreover, the layout of each component is compact. The first collection frame 43 and the second collection frame 33 are arranged side by side on the outside of the turntable 21. The corresponding first pneumatic blowing element 41 and the second pneumatic blowing element 31 are arranged in a ring array on the turntable 21, which optimizes the production space.

[0020] In this embodiment of the present invention, both the first guide chute 42 and the second guide chute 32 are covered with a baffle plate 5. The baffle plate 5 extends to the discharge end above the first collection frame 43 and the second collection frame 33, which can improve the accuracy and stability of material collection, prevent the material from derailing and popping out of the guide chute when it is blown out, and also reduce the noise of material falling to a certain extent, thus optimizing the working environment.

[0021] Furthermore, partitions 6 are provided between the first collection frame 43 and the second collection frame 33, as well as between adjacent second collection frames 33, to prevent different types of materials from bouncing to the side after falling. This effectively blocks material splashing, prevents different types of materials from mixing, ensures accurate classification of collected materials, improves the standardization of material management and the convenience of subsequent processing, and facilitates the orderly progress of the production process.

[0022] The feeding assembly 1 of this utility model includes a vibratory plate 11 and a flat vibrating mechanism 12. The flat vibrating mechanism 12 is connected between the discharge end of the vibratory plate 11 and the feed end of the turntable 21. In the feeding assembly 1, the vibratory plate 11 arranges the material in an orderly manner and starts to convey it to the flat vibrating mechanism 12, thereby smoothly transferring the material from the vibratory plate 11 to the turntable 21, avoiding the risk of material jamming and accumulation, and making the feeding process uniform and continuous.

[0023] Vision sorting machines typically perform high-speed detection and sorting, resulting in a rapid consumption of residual material in the material tray. To avoid increasing labor costs by requiring operators to repeatedly add material, this invention provides an automatic feeding bin 13 on the side of the vibrating plate 11 away from the flat vibration mechanism 12. The discharge end of the automatic feeding bin 13 is equipped with a sensing mechanism 131 for detecting the remaining material in the vibrating plate 11. By monitoring the remaining material in the vibrating plate 11 through the sensing mechanism 131, the automatic feeding bin 13 immediately starts the replenishment program once the material level approaches the lower limit. In this way, it effectively ensures that the feeding component 1 continuously and stably supplies materials to the vision sorting machine, reducing the risk of production stoppage due to material shortage.

[0024] The CCD detection mechanism 22 in this embodiment includes a ring array of contour CCDs, surface defect CCDs, color recognition CCDs, and size measurement CCDs arranged on a turntable 21. The contour CCDs can identify material shape defects, the surface defect CCDs can accurately locate scratches, the color recognition CCDs can identify color deviations, and the size measurement CCDs can determine size discrepancies. Through precise detection, NG materials can be accurately classified and collected, improving classification accuracy and efficiency, facilitating subsequent targeted processing, and optimizing the production quality control process.

[0025] The outer ring of the turntable 21 used for feeding material in this utility model is made of transparent glass. Its good light transmittance allows the CCD detection mechanism 22 to clearly capture the image of the material and obtain accurate appearance information, which greatly improves the detection accuracy. For the classification and collection of NG materials, it can more accurately identify minor defects and effectively avoid misjudgment, thereby ensuring that different types of NG materials and good products are correctly classified and collected.

[0026] The above embodiments are merely preferred embodiments of the present utility model and are only used to explain the present utility model, not to limit the present utility model. Any changes, substitutions, combinations, simplifications, modifications, etc., made by those skilled in the art without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
