Description

Technical Field

[0001] This invention relates to the field of material sorting technology, specifically to an image sorting device and method for plastic bottle flakes. Background Technology

[0002] In the plastics sorting industry, there are hundreds or even thousands of types of plastics, and most of them are grayish-white or translucent. Due to their similar colors, traditional color sorting is difficult to apply to plastics sorting. Especially in the recycling of recycled plastics, it enables efficient sorting of recycled plastic granules such as PET, PP, PE, PS, and PVC. Plastic granules often have problems such as mixed materials, similar colors, transparency / semi-transparency, aging, fluorescent additives, stains, and impurities.

[0003] Existing sorting technologies have significant drawbacks. Color sorting relies solely on visible light color and cannot distinguish between different materials of the same color. Near-infrared spectroscopy suffers severe signal attenuation in dark and black plastics, leading to recognition failure. Single-source imaging is susceptible to interference from particle shape, thickness, and shadows, resulting in a high misjudgment rate for materials with low color difference. Fluorescence sorting is mostly based on single-mode acquisition and does not incorporate transmission / reflection enhancement features, resulting in insufficient accuracy.

[0004] Therefore, the accuracy of recycling recycled plastic pellets needs to be improved. Summary of the Invention

[0019] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0020] To achieve the above objectives, please refer to Figure 1-6 The present invention provides an image sorting device and method for plastic bottle flakes, which provides the following technical solution.

[0021] Specifically, such as Figure 1-4 The image sorting device for plastic bottle flakes shown mainly comprises a detection platform assembly 1, a column electrical box assembly 2, a camera and lighting assembly 3, and a switch assembly 4. The column electrical box assembly 2 is fixedly installed on the side of the detection platform body 100, and the camera and lighting assembly 3 is installed on the top of the column electrical box assembly 2.

[0022] The image sorting device for plastic bottle flakes is described from top to bottom as follows: The camera and lighting assembly 3 has a camera and lighting body 300, and a camera 301 is installed at the center of the bottom of the camera and lighting body 300. The camera 301 is equipped with a fill light for providing fill light when taking pictures.

[0023] The column electrical box assembly 2 includes a column electrical box body 200, inside which an electrical control module 201 is installed. The electrical control module 201 is used to control the circuit system. A data display screen 202 is embedded on the inner side of the column electrical box body 200 for displaying images and data. The electrical control module 201 is used to control and transmit electrical signals, and to display the images taken by the camera 301 on the data display screen 202.

[0024] The testing platform component 1 has a testing platform body 100. A negative pressure plastic sheet recycling port 105 is installed at the connection between the testing platform body 100 and the column electrical box body 200. The selected qualified recycling objects enter the recycling channel through the negative pressure plastic sheet recycling port 105.

[0025] Located directly below the camera 301, a soft light glass plate 104 is installed for placing sorting objects. The soft light glass plate 104 can make the light evenly distributed when the light passes through it, so that the light shining from the bottom on the object placed on it is uniform, which helps to improve the uniformity and consistency of the image.

[0026] A ring-shaped white light 103, or a planar white light, is installed at the bottom of the diffused glass panel 104 to illuminate it. The white light 103 is controlled to turn on and off via a white light switch 401.

[0027] Furthermore, a black screen 1010 is installed between the soft light glass plate 104 and the white light source, close to the soft light glass plate 104. The black screen 1010 covers the bottom of the soft light glass plate 104, blocking light from shining from the bottom of the soft light glass plate 104 onto the sorting object, thus providing a black background for the camera 301.

[0028] Furthermore, multiple ultraviolet lamps 302 arranged in a ring array are arranged around the camera 301. The ultraviolet lamps 302 are controlled to turn on and off via an ultraviolet lamp switch 402.

[0029] Furthermore, a black curtain assembly 101 is installed between the diffused glass panel 104 and the white light source. The black curtain assembly 101 has a curtain tension roll 1011, which contains a retractable black curtain 1010. The outer end of the black curtain 1010 is fixed to a curtain rod 1013. In use, the curtain rod 1013 is stretched to unfold the black curtain 1010. After use, the curtain rod 1013 is released, and the black curtain 1010 automatically retracts into the curtain tension roll 1011.

[0030] Furthermore, the black screen assembly 101 has drive mechanism main supports 1012 distributed on both sides of the diffused glass plate 104. A screen drive roller 1014 is mounted at one end of the drive mechanism main supports 1012, and a screen driven roller 1015 is provided at the other end. The screen drive roller 1014 and the screen driven roller 1015 are driven by a screen roller transmission belt 1016. Of course, either the screen drive roller 1014 or the screen driven roller 1015 can serve as either the drive roller or the driven roller.

[0031] The end of the curtain rod 1013 is fixedly installed on the curtain roller drive belt 1016. The curtain rod 1013 is driven by the reciprocating motion of the curtain roller drive belt 1016, thereby extending and retracting the black curtain 1010.

[0032] Furthermore, a cleaning scraper 1020, which can reciprocate back and forth, is installed on the soft light glass plate 104 to scrape away the sorted objects.

[0033] Furthermore, a plastic sheet cleaning squeegee assembly 102 is installed on the diffused glass plate 104. The plastic sheet cleaning squeegee assembly 102 has a cleaning squeegee 1020. The plastic sheet cleaning squeegee assembly 102 also has vertical cleaning squeegee supports 1022 distributed on both sides of the diffused glass plate 104. A horizontal cleaning squeegee support 1021 is connected and installed at the upper end of the vertical support. The cleaning squeegee 1020 is fixedly installed on the horizontal cleaning squeegee support 1021.

[0034] Furthermore, a scraper drive roller 1024 is fixedly installed at one end of the drive mechanism main support 1012, and a scraper driven roller 1025 is fixedly installed at the other end. The scraper drive roller 1024 and the scraper driven roller 1025 are driven by the scraper roller transmission belt 1026. Of course, either the scraper drive roller 1024 or the scraper driven roller 1025 can be used as the drive roller or the driven roller.

[0035] The lower end of the vertical support 1022 for cleaning scraper is fixedly installed on the scraper roller drive belt 1026, which drives the cleaning scraper 1020 to reciprocate.

[0036] Furthermore, the curtain roll 1011 and the cleaning scraper 1020 are located at the end away from the negative pressure plastic sheet recycling port 105. When the black curtain 1010 is unfolded, the cleaning scraper 1020 remains in the same position. When the black curtain 1010 is retracted, the cleaning scraper 1020 moves towards the negative pressure plastic sheet recycling port 105, scraping the qualified sorted objects into the negative pressure plastic sheet recycling port 105 and entering the recycling channel.

[0037] The existing ultraviolet lamps are positioned directly above the objects to be sorted, illuminating only the upper surface and not directly the sides. This results in shadows on the sides of the objects during imaging under ultraviolet light, which is detrimental to image quality and the sorting of plastic particles. To address this issue, further improvements are needed, such as... Figure 5-6 As shown.

[0038] Furthermore, a side UV lamp column 501 is provided directly above the soft light glass plate 104, which has a side UV lamp column inclined surface 502, and an inclined UV lamp 503 is provided perpendicular to the side UV lamp column inclined surface 502; column extension brackets 601 are provided on two sides of the column electrical box body 200, and two symmetrically distributed facade reflectors 603 are rotatably connected to the column extension brackets 601 through a rotating shaft 602. The light emitted by the inclined UV lamp 503 is reflected to the side of the sorting object through the facade reflectors 603.

[0039] Furthermore, the angle between the inclined surface 502 of the side UV lamp column and the vertical surface is 50 degrees, and the angle between the vertical reflector 603 and the vertical surface is 10 degrees; the upper edge of the vertical reflector 603 extends to provide an inclined reflector 604, and the light reflected from the sorting object is reflected by the inclined reflector 604 to the opposite vertical reflector 603, and then reflected to the side of the sorting object.

[0040] Furthermore, a screening grid plate 7 for accommodating sorted objects is placed on the soft light glass plate 104. Screening grid grooves 701 are arranged in a horizontal X-axis and Y-axis array on the plate. The screening grid grooves 701 extend through the plate and are approximately the same height as the sorted objects. This design allows the sorted objects to be distributed in a single layer, preventing them from overlapping and causing overlapping images when taking pictures, which would affect the picture quality.

[0041] The screening grid groove 701 is through, so after the sorting is completed, the screening grid plate 7 can be removed and the sorted objects will remain directly on the soft light glass plate 104.

[0042] The screening grid slots 701 are distributed along the X-axis to both sides and gradually increase in size. This is to allow for the use of sorting objects of different sizes. Generally, larger objects are placed in the larger grid slots on the side, while smaller objects are left in the middle. The middle has better lighting, which is more conducive to taking pictures and selecting smaller sorting objects.

[0043] Furthermore, the screening grid plate 7 is composed of multiple grid plate layers of different thicknesses, including a first grid plate layer 71, a second grid plate layer 72, a third grid plate layer 73, and so on. In use, grid plate layers of different thicknesses are stacked to make the height of the stacked grid plate layers roughly equal to the height of the objects to be sorted. Then, a cleaning scraper 1020 is used to scrape off any objects that are too tall or too large, and the process continues until the height of the stacked grid plate layers is adjusted to ensure that the objects fall completely into the grid grooves, and then sorting is performed again.

[0044] Before the camera 301 takes a picture, the cleaning scraper 1020 scrapes the sorted objects placed on the screening grid plate 7 into the screening grid groove 701, and removes the sorted objects that the screening grid groove 701 cannot accommodate.

[0045] After screening, remove the screening grid plate 7 and use the cleaning scraper 1020 to scrape the qualified sorted objects left on the soft light glass plate 104 into the recycling channel.

[0046] The upper surface of the detection platform body 100 is equipped with a switch assembly 4, which includes a white light switch 401, an ultraviolet light switch 402, a curtain drive switch 403, and a cleaning scraper drive switch 404. The white light switch 401, ultraviolet light switch 402, curtain drive switch 403, and cleaning scraper drive switch 404 control their respective components.

[0047] The specific work process is as follows: Step 1: Press the white light switch 401 to turn on the white light 103, enter the soft light mode, and take a picture; Step 2: Press the white light switch 401 to turn off the white light 103. Press the screen drive switch 403 to unfold the black screen 1010. Enter black background mode, turn on the camera 301 fill light and take a picture; Step 3: Keep the white light 103 off and the black curtain 1010 unfolded. Press the UV light switch 402 to turn on the UV light 302 and take a picture.

[0048] Step 4: Press the white light switch 401 to turn on the white light 103. Press the screen drive switch 403 to retract the black screen 1010. Enter soft light mode, turn on UV light 302, and take a picture.

[0049] Step 5: Layer and overlay the photo slices. Then align the selected objects in the images taken in steps one through four; Step Six: The AI ​​edge computing module in electrical control module 201 begins operation. The colors and brightness of the sliced ​​and layered photos were compared, analyzed, and sorted.

[0050] Step 7: Press the cleaning scraper drive switch 404. The cleaning scraper 1020 scrapes the qualified sorted objects into the negative pressure plastic sheet recycling port 105.

[0051] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
