Technical Field
[0001] This application relates to the field of automatic grading technology, and in particular to an online high-speed grading device. Background Technology
[0002] After production, products generally require inspection. Currently, inspection mainly relies on manual labor or machine vision. Manual methods are suitable for inspecting low-cost, small-quantity, and low-precision products. Machine vision methods are suitable for fields with a certain economic foundation and high-volume, high-precision product inspection.
[0003] Currently, after products undergo machine vision inspection, they need to be sorted into grades on a conveyor belt. However, the current method of using electric or pneumatic pushers to push products on the conveyor belt to different channels for classification is still insufficient to meet the requirements of online high-speed grading, affecting the efficiency of grading and requiring improvement. Summary of the Invention
[0004] In view of this, the purpose of this application is to provide an online high-speed grading device to achieve the goal of high-speed grading. The specific solution is as follows:
[0005] An online high-speed grading device includes a frame, the frame being equipped with a conveyor track mechanism and a high-speed grading mechanism that matches the conveyor track mechanism and performs detection and grading on the conveyed products; wherein:
[0006] The conveying track mechanism consists of at least two parallel tracks and includes a feeding end and a discharging end located at both ends of the conveying track mechanism. One track located at the feeding end is used for feeding, and all tracks located at the discharging end are used for graded discharging.
[0007] The high-speed grading mechanism is equipped with at least one grading unit for classifying products fed from the feed end to other tracks.
[0008] Preferably, feeding baffles are provided on both sides of the corresponding track within the feeding end, and a feeding section is formed between the two feeding baffles; both sides of the discharging end are provided with discharging baffles, and when there are three tracks, a primary discharging section located in the middle and a secondary discharging section and a tertiary discharging section located on both sides of the primary discharging section are formed between the two discharging baffles.
[0009] Preferably, the frame is provided with a plurality of adjusting support rods that abut against the side opposite to the feed baffle and the side opposite to the discharge baffle, respectively.
[0010] Preferably, the high-speed grading mechanism includes a protective cover fixed to the frame, and the grading unit is fixed to the front and / or rear side of the protective cover.
[0011] Preferably, the grading unit is provided with multiple rotating grading fan blades and a drive motor for driving the rotating grading fan blades to rotate circumferentially; the rotating grading fan blades are used to grade products moving on the conveying path along the vertical direction of the material conveying path.
[0012] Preferably, the outer end of the rotating graded fan blade is provided with a plurality of arrayed holes.
[0013] Preferably, the outer end of the rotating graded fan blade is provided with a groove located on the side facing the rotation direction.
[0014] Preferably, the grading unit is provided with a proximity switch, which is used to locate the position of the rotating grading fan blade after one grading action, and when it deviates from the set position, the drive motor drives the rotating grading fan blade to reset.
[0015] As can be seen from the above solutions, this application provides an online high-speed grading device, which has the following beneficial effects:
[0016] 1. The product is graded by mechanically controlled grading fan blades, which effectively avoids the problem of slow grading action caused by insufficient air pressure.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0025] like Figure 1 As shown, an online high-speed grading device includes a frame 1. A conveyor track mechanism 2 and a high-speed grading mechanism 3, which matches the conveyor track mechanism 2 and performs detection and grading of the conveyed products, are arranged on the top of the frame 1. In this embodiment, the high-speed grading mechanism 3 is mounted horizontally across the upper middle portion of the conveyor track mechanism 2, thereby detecting and grading the feed products moving along the conveyor track mechanism 2. The detection is performed using existing vision sensing systems and rating evaluation systems, and adjustments can be made to the input of specific evaluation and rating parameters to apply to different specifications and models of feed products; details are not elaborated here.
[0026] It should be mentioned that the conveyor track mechanism 2 consists of at least two parallel tracks and includes a feed end 21 and a discharge end 22 located at both ends of the conveyor track mechanism 2. In this embodiment, there are three tracks, and the track located in the middle is used as the main track. Therefore, the main track is used for feeding at one end of the feed end 21, and for discharging graded products that have not undergone rejection processing at the other end. Generally, the products fed into the main track are set as qualified or acceptable products, which are detected by visual sensing. The other end of the main track, along with the other two tracks, is used for graded discharge, so as to combine with the high-speed grading mechanism 3 to realize the separation of the fed products into three grades for discharge.
[0027] like Figure 1, Figure 2 As shown, the high-speed grading mechanism 3 is provided with at least one grading unit 32 for grading the products fed into the feed end 21 to other tracks. In this embodiment, in order to effectively divide the fed products into three levels and discharge them separately, there are two grading units 32, which are used to grade the fed products on the main track to adjacent tracks respectively.
[0028] It should be noted that, in order to improve the stability of product feeding and discharging, and to prevent product rebound from affecting the product grading accuracy, feed baffles 212 are provided on both sides of the corresponding track inside the feed end 21, and a feed section 211 is formed between the two feed baffles 212. Discharge baffles 224 are provided on both sides of the discharge end 22, and a primary discharge section 221 is formed between the two discharge baffles 224, with a secondary discharge section 222 and a tertiary discharge section 223 located on either side of the primary discharge section 221. The height of the secondary discharge section 222 and the tertiary discharge section 223 is lower than that of the primary discharge section 221. Meanwhile, multiple adjusting support rods 23 are provided on the frame 1, which abut against the side opposite to the feed baffle 212 and the side opposite to the discharge baffle 224, respectively. This can improve the fixing stability of the feed baffle 212 and the discharge baffle 224 by adjusting the support rods 23, while reducing the difficulty of adjusting the distance between the feed baffle 212 and the discharge baffle 224.
[0029] To improve safety, the high-speed grading mechanism 3 includes a protective cover 31 fixed on the frame 1, and two grading units 32 are fixed on the front and rear sides of the protective cover 31, respectively, so as to effectively drive the detected and graded feed products to be discharged along the corresponding primary discharge section 221, secondary discharge section 222 or tertiary discharge section 223.
[0030] like Figure 2 As shown, the grading unit 32 is equipped with multiple rotating grading blades 322 and a drive motor 321 that drives the rotating grading blades 322 to rotate circumferentially. The drive motor 321 is a stepper motor or a drive-controlled motor, used to control the multiple rotating grading blades 322 to rotate by a set arc, so that the multiple rotating grading blades 322 directly reject and grade the material moving on the conveying path during the rotation. During the material rejection process, the rotating grading blades 322 reject the material moving on the conveying path along the direction perpendicular to the material conveying path. Therefore, it effectively avoids the influence of material movement and rejection on the positional displacement of other materials.
[0031] To enhance the material rejection and classification effect of the classification unit 32, multiple arrayed holes 3221 and grooves 3222 located on the side facing the rotation direction are provided on the outer end of the rotating classification fan blade 322. The holes 3221 reduce airflow formation, thus minimizing its impact on material transport and rejection stability. The grooves 3222 effectively limit the material during rejection, further improving the stability of material classification. Simultaneously, the classification unit 32 is equipped with a proximity switch 323. The proximity switch 323 is used to position the rotating classification fan blade 322 after one rejection action, and when it deviates from the set position, the drive motor 321 drives the rotating classification fan blade 322 to reset. Therefore, after the rotating classification fan blade 322 completes the rejection action, with the assistance of the proximity switch 323, it ensures that the rotating classification fan blade 322 is located in the set position and awaits continued drive operation, thereby improving the product classification effect and stability.
[0032] In summary, this application provides an online high-speed grading device. This device achieves product grading through the operation of mechanically controlled grading fan blades, effectively avoiding the problem of slow grading action caused by insufficient air pressure. It also employs multiple tracks for product grading and discharge, improving discharge efficiency and preventing mutual interference between graded products, thus achieving the goal of high-speed grading. Specifically, the grading unit 32 drives the rotating grading fan blades 322 via a drive motor 321, directly grading the material moving along the conveying path outside the path. This improves the efficiency of grading products fed through the feeding section 211 to the secondary discharge section 222 and the tertiary discharge section 223. Simultaneously, the holes 3221 reduce airflow formation that could affect material conveying and grading stability, and the grooves 3222 effectively limit the material during grading, further enhancing the stability of material grading.
