Abstract
Description
Technical Field
[0001] This utility model relates to a sorting mechanism, specifically a waste sorting mechanism based on CCD. Background Technology
[0002] There is a material that needs to be sorted after production to separate qualified and unqualified products. The main difference between qualified and unqualified products lies in their appearance (products with scratches or other cosmetic defects). Traditional sorting methods rely on workers visually inspecting the products and then manually placing them into the corresponding receiving area. However, manual sorting is inefficient and prone to errors due to worker fatigue, leading to incorrect sorting and affecting product quality. Therefore, a CCD-based waste sorting mechanism was designed to address these issues.
[0003] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this utility model and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this utility model. Utility Model Content
[0004] To overcome the shortcomings of the prior art, the purpose of this utility model is to provide a waste sorting mechanism based on CCD.
[0005] To achieve the above and other related objectives, the technical solution provided by this utility model is: a CCD-based waste sorting mechanism, comprising:
[0006] Mounting frame, the upper end of which is equipped with a CCD detection device;
[0007] The first feed chute is located at the upper end of the mounting frame and is used for feeding qualified materials.
[0008] The second feed chute is located at the upper end of the mounting frame; it is used for feeding non-conforming waste materials.
[0009] The first material discharge channel is located inside the mounting frame and is connected to the lower end of the first feeding trough.
[0010] The second material discharge channel is located inside the mounting frame and is connected to the lower end of the second feeding trough.
[0011] A receiving hopper is located inside the mounting frame and below the first material discharge channel;
[0012] A waste bin is located inside the mounting frame, below the second material discharge channel and connected to the outlet of the second material discharge channel.
[0013] Furthermore, the mounting frame is internally equipped with a partition, and the partition has a material discharge port; both the first material discharge channel and the second material discharge channel are located above the partition; the receiving hopper is located below the partition, the discharge port of the first material discharge channel is located above the material discharge port, and the material from the first material discharge channel falls into the receiving hopper below through the material discharge port; the waste bin is located above the partition.
[0014] Furthermore, several receiving bins are provided, each mounted on a material carrier tray. The material carrier tray is rotatably mounted on the mounting frame and is connected to a motor for transmission. In this design, by mounting several receiving bins on a rotatable material carrier tray, the receiving bins can be replaced by rotating the tray.
[0015] Furthermore, the receiving bins are evenly distributed around the center line of the loading tray. In this design, when the receiving bins are repositioned by the loading tray, they can be aligned with the material discharge port to ensure effective material receiving. The number of receiving bins is greater than or equal to two.
[0016] Furthermore, a bending section is provided in the middle of the first material feeding channel. In this design, the bending degree of the bending section is such that the material can slide smoothly downwards. The bending section prevents the material from falling directly vertically, avoiding damage to the material bucket due to large impact forces, and also reduces noise.
[0017] Furthermore, the bending section includes an inclined section one and an inclined section two, with the inclination directions of inclined section one and inclined section two being opposite. In this design, the inclined channel allows the material to fall more smoothly, reducing the impact force at the end and improving operational safety. The slow descent also reduces material falling noise. The number of inclined sections can be greater than two.
[0018] Furthermore, the waste bin is fixedly connected to the outlet of the second material discharge channel, and a cleaning port is provided on one side of the waste bin. In this design, the cleaning port facilitates the regular removal of waste from the waste bin by workers, preventing the waste bin from becoming full.
[0019] Furthermore, the second material drop channel is inclined. In this design, the time required for an object to reach the same vertical height is longer in the inclined channel than in the vertical channel. The inclined channel gradually dissipates energy through a longer path, reducing the impact force at the end and reducing material drop noise.
[0020] Furthermore, both the first and second feed troughs are funnel-shaped, wider at the top and narrower at the bottom. In this design, the sloping structure of the funnel naturally guides the material downwards, reducing blockages caused by accumulation or jamming.
[0021] Furthermore, two CCD detection devices are provided, located on one side of the first feed trough and one side of the second feed trough, respectively, with the two CCD detection devices arranged opposite each other. In this solution, a robotic arm can be used to transfer the material (product) between the two CCD detection devices, allowing for detection on both sides of the material, resulting in better detection performance.
[0022] Due to the application of the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:
[0023] The waste sorting mechanism based on CCD designed in this utility model can identify the appearance of materials through CCD detection devices, and after analysis by the control system, it can quickly sort the materials with the help of a robotic arm. It can quickly distinguish between qualified and unqualified products and quickly transfer them to the corresponding receiving area. The sorting efficiency is high and it is not easy to make mistakes, thus ensuring the quality of the products leaving the factory. Attached Figure Description

[0032] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.
[0033] Example:
[0034] This embodiment provides a CCD-based waste sorting mechanism, see attached document. Figure 1 and attached Figure 2 As shown, it includes:
[0035] Mounting frame 1, with a CCD detection component 2 mounted on its upper end; see appendix. Figure 1 As shown, two CCD detectors 2 are provided, located on one side of the first feed trough 3 and one side of the second feed trough 4, respectively, with the two CCD detectors 2 facing each other. A robotic arm can be used to transfer materials (products) between the two CCD detectors 2, performing detection on both sides of the material. The CCD detectors 2 and the robotic arm are connected to the control system. After obtaining the detection and analysis results, the robotic arm places qualified products into the first feed trough 3 and unqualified products into the second feed trough 4.
[0036] The first feed chute 3 is located at the upper end of the mounting frame 1; it is used for feeding qualified materials.
[0037] The second feed chute 4 is located at the upper end of the mounting frame 1; it is used for feeding unqualified waste materials.
[0038] The first material discharge channel 5 is located inside the mounting frame 1 and is connected to the lower end of the first feeding trough 3.
[0039] The second material discharge channel 6 is located inside the mounting frame 1 and is connected to the lower end of the second feeding trough 4.
[0040] The receiving bucket 7 is located inside the mounting frame 1 and below the first material discharge channel 5;
[0041] Waste bin 8 is located inside the mounting frame 1. Waste bin 8 is located below the second material discharge channel 6 and is connected to the discharge port of the second material discharge channel 6.
[0042] See appendix Figure 1 and attached Figure 2 As shown, the mounting frame 1 has a partition 9 inside, and a material discharge port 10 is opened on the partition 9; the first material discharge channel 5 and the second material discharge channel 6 are both located above the partition 9; the receiving bucket 7 is located below the partition 9, and the discharge port of the first material discharge channel 5 is located above the material discharge port 10. The material from the first material discharge channel 5 falls into the receiving bucket 7 below through the material discharge port 10; the waste bin 8 is located above the partition 9.
[0043] The waste bin 8 is fixedly connected to the outlet of the second discharge channel 6, and a cleaning port 14 is provided on one side of the waste bin 8. The waste bin 8 is a square bin, and one side of the square bin is not closed and serves as the cleaning port 14, which faces outwards from the mounting frame 1. The design of the cleaning port 14 facilitates the regular removal of waste from the waste bin 8 by the staff, preventing the waste bin 8 from becoming full. The second discharge channel 6 is inclined. In the inclined channel, the time required for an object to reach the same vertical height is longer than in the vertical channel. The inclined channel gradually dissipates energy through a longer path, reducing the impact force at the end and reducing the noise of the material falling. Both the first feed trough 3 and the second feed trough 4 are funnel-shaped, wider at the top and narrower at the bottom. The inclined structure of the funnel naturally guides the material downwards and concentrates it, reducing blockages caused by accumulation or jamming.
[0044] See appendix Figure 2 and attached Figure 3 As shown, several receiving bins 7 are arranged on a material carrier tray 11, which is rotatably mounted on the mounting frame 1 and connected to a motor 12. The receiving bins 7 are arranged on the rotatable material carrier tray 11, allowing for replacement of the receiving bins 7 by rotating the tray. For example, after the first receiving bin 7 is filled with 100 pieces of material (requiring a relevant sensor for counting) or after 30 minutes of material collection (requiring a relevant timer), the second receiving bin 7 is rotated via the material carrier tray 11 to below the discharge port of the first discharge channel 5 to continue collecting material. The receiving bins 7 are evenly distributed around the center line of the material carrier tray 11. When the receiving bins 7 are repositioned via the material carrier tray 11, they can be aligned with the discharge port 10 to ensure effective material collection. The number of receiving bins 7 is greater than or equal to two.
[0045] See appendix Figure 3 As shown, a bending section 13 is provided in the middle of the first material discharge channel 5. The bending degree of the bending section 13 is such that the material can slide down smoothly. The bending section 13 prevents the material from falling vertically directly, avoiding damage to the material bucket 7 due to large impact force, and also reduces noise. The bending section 13 includes an inclined section one 131 and an inclined section two 132, with the inclination direction of inclined section one 131 being opposite to that of inclined section two 132. The inclination angles of inclined section one 131 and inclined section two 132 are both 30°~45°. The inclined channel makes the material drop process relatively smoother, reduces the impact force at the end, and improves operational safety. Slow sliding also reduces material discharge noise. The number of inclined sections can be more than two, and the inclination directions of adjacent inclined sections are opposite.
[0046] The waste sorting mechanism based on CCD designed in this utility model can identify the appearance of materials through CCD detection devices, and after analysis by the control system, it can quickly sort the materials with the help of a robotic arm. It can quickly distinguish between qualified and unqualified products and quickly transfer them to the corresponding receiving area. The sorting efficiency is high and it is not easy to make mistakes, thus ensuring the quality of the products leaving the factory.
[0047] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
