Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0060] The following is for reference. Figures 1-15 The analyzer 100 according to an embodiment of the present invention is described.
[0061] According to the analyzer 100 of this utility model embodiment, such as Figure 1 and Figure 2 As shown, the analyzer 100 includes: a feeding unit 1, a receiving unit 2, a transmission unit 3, and an identification unit 4. The transmission unit 3 includes: a support frame 31, a drive shaft 32, a driven shaft 33, a transmission belt 34, and a drive component 35. The drive shaft 32 and the driven shaft 33 are spaced apart on the support frame 31 along the transmission direction X of the transmission unit 3. The transmission belt 34 is fitted on the drive shaft 32 and the driven shaft 33. A portion of the transmission belt 34 is located below the feeding unit 1 to receive material 200, and another portion of the transmission belt 34 extends to the receiving unit 2 to deliver material 200. At least a portion of the upper surface of the transmission belt 34 forms a transmission channel 3a for holding material 200. The identification unit 4 is located on the material conveying route from the feeding unit 1 to the receiving unit 2.
[0062] Material 200 enters from the feeding unit 1, the transmission unit 3 drives the material 200, and after being identified by the identification unit 4, the material 200 is distributed to the receiving unit 2 and sent out from the analyzer 100.
[0063] In related technologies, analyzers are primarily used for imperfect grain analysis of grains such as rice to evaluate and improve the processing and sorting quality of front-end equipment in production lines. These analyzers mostly use a conveyor system to identify each grain individually, resulting in low efficiency and numerous limitations on material morphology.
[0064] The analyzer 100 of this utility model embodiment adopts a transmission unit 3 with a transmission belt 34 to transport materials 200, so that the analyzer 100 can be used to analyze more types of materials 200 and the analyzer 100 can be applied to a wider range of fields.
[0065] The transmission unit 3 includes a support frame 31, a drive shaft 32, a driven shaft 33, and a drive element 35, all mounted on the support frame 31. Both the drive shaft 32 and the driven shaft 33 are rotatably mounted on the support frame 31. A transmission belt 34 is fitted onto the drive shaft 32 and the driven shaft 33. The drive element 35 is connected to the drive shaft 32 and drives the drive shaft 32 to rotate actively. The transmission belt 34, fitted onto the drive shaft 32 and the driven shaft 33, moves under the action of friction and also drives the driven shaft 33 to rotate passively, thus enabling the transmission belt 34 to move smoothly.
[0066] At least a portion of the drive belt 34 is located below the feeding unit 1. The material 200 can fall from the feeding unit 1 onto the drive belt 34 under the action of gravity. At least a portion of the drive belt 34 extends to the receiving unit 2 to convey the material 200 to the receiving unit 2. The portion of the drive belt 34 from receiving the material 200 to conveying the material 200 constitutes the conveying channel 3a, that is, a portion of the upper surface of the drive belt 34 constitutes the conveying channel 3a for holding the material 200.
[0067] The identification unit 4 is located on the material conveying route from the feeding unit 1 to the receiving unit 2. The material conveying route refers to the complete movement route of the material 200 from the feeding unit 1 to the receiving unit 2, including the movement route of the material 200 on the conveyor belt 34 and the movement route of the material 200 in the air under the action of gravity. Therefore, the identification unit 4 can detect the material 200 falling onto the conveyor belt 34, as well as the material 200 in the air. It can detect the material 200 from 360 degrees without blind spots, so as to realize the quality of the material 200 such as shape and size, or the content of impurities, to meet various detection needs. This allows the analyzer 100 to be used to analyze more types of materials 200, and the analyzer 100 can be applied to a wider range of fields.
[0068] According to the present invention, the analyzer 100 uses a transmission unit 3 with a transmission belt 34 to transport materials 200. The transmission belt 34 can not only carry grains such as rice, but also nuts, fruits and vegetables, Chinese herbal medicines, plastic sheets and other materials 200. Furthermore, the identification unit 4 can detect materials 200 from multiple angles, which can meet the detection needs of various materials 200, so that the analyzer 100 can be used to analyze more kinds of materials 200 and the analyzer 100 can be applied to a wider range of fields.
[0069] In some embodiments of this utility model, such as Figure 2 As shown, the transmission unit 3 further includes: a baffle 36, which is arranged along the transmission direction X of the transmission unit 3 and is located above the upper surface of the transmission belt 34; the baffles 36 are arranged in pairs, with the two baffles 36 in the same pair arranged at intervals along the width direction of the transmission belt 34, and the portion of the upper surface of the transmission belt 34 between the two baffles 36 in the same pair forms a transmission channel 3a.
[0070] Baffles 36 extend along the conveying direction X of the transmission unit 3. Pairs of baffles 36 are spaced apart in a direction perpendicular to the transmission direction of the transmission unit 3 and are spaced apart along the width direction of the transmission belt 34. The upper surface portion of the transmission belt 34 defined between the baffles 36 forms the conveying channel 3a. By setting baffles 36, the conveying path range of the material 200 can be limited, improving the situation where the material 200 comes off the transmission belt 34 during the transmission process and enhancing the working reliability of the transmission unit 3.
[0071] For materials 200 of different sizes, the same or different baffles 36 can be used to define different ranges of conveying channels 3a to meet the conveying needs of various materials 200, so that the analyzer 100 can be used to analyze more types of materials 200 and the analyzer 100 can be applied to a wider range of fields.
[0072] It is worth noting that the baffle 36 can be a pair, that is, two baffles 36 are arranged along the width direction of the transmission belt 34; or, the baffle 36 can be multiple pairs. Optionally, multiple pairs of baffles 36 can be arranged sequentially along the transmission direction of the transmission unit 3, so that multiple pairs of baffles 36 together define an entire transmission channel 3a; alternatively, multiple pairs of baffles 36 can be spaced apart along the width direction of the transmission belt 34, so that multiple pairs of baffles 36 can define multiple parallel transmission channels 3a.
[0073] In some embodiments of this utility model, such as Figure 2 As shown, the baffle 36 is inclined relative to the upper surface of the transmission belt 34.
[0074] In some embodiments of this utility model, such as Figure 2As shown, the transmission unit 3 also includes a first support rod 37, one end of which is detachably connected to the support frame 31, and a baffle 36 is installed at the other end of the first support rod 37.
[0075] The first support rod 37 supports the baffle 36, which can improve the arrangement stability and structural reliability of the baffle 36, improve the displacement or damage of the baffle 36 under the impact of the material 200, and improve the working stability of the baffle 36.
[0076] In some embodiments of this utility model, such as Figure 2 As shown, each baffle 36 is provided with a plurality of first support rods 37, which are spaced apart along the transmission direction X of the transmission unit 3, thereby improving the structural stability of the baffle 36 at multiple points along its length.
[0077] In some embodiments of this utility model, one end of the first support rod 37 is screwed to the support frame 31 and the other end of the first support rod 37 is screwed to the baffle 36, which not only improves the connection stability but also facilitates disassembly and assembly.
[0078] In some embodiments of this utility model, such as Figures 2-4 As shown, the support frame 31 includes: a tray 311, which is arranged along the transmission direction X of the transmission unit 3; and a transmission belt 34, which is an annular belt, with the upper half of the transmission belt 34 located above the tray 311.
[0079] The pallet 311 extends along the transmission direction X of the transmission unit 3. The transmission belt 34 is an annular belt. The movement of the transmission belt 34 is a circular movement. The pallet 311 supports the upper part of the transmission belt 34. The transmission belt 34 is supported by the pallet 311 when it moves, so as to ensure the stability of the material 200 when it is transported on the upper surface of the transmission belt 34.
[0080] In some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, Figure 3 and Figure 4 As shown, the tray 311 includes a straight section 3111 and two curved sections 3112. The two curved sections 3112 are connected to both ends of the straight section 3111, and each curved section 3112 is bent downward at a point away from the straight section 3111.
[0081] The upper part of the transmission belt 34 is supported by the support plate 311, and the rotating part of the transmission belt 34 is supported by the bending section 3112 to produce bending, which can improve the motion stability of the transmission belt 34.
[0082] In some embodiments of this utility model, the curved section 3112 is constructed in an arc shape, which can reduce the friction between the support plate 311 and the transmission belt 34 and improve the smoothness of the movement of the transmission belt 34.
[0083] In some embodiments of this utility model, the pallet 311 is constructed of stainless steel, which improves the wear resistance of the pallet 311 and reduces the friction between the pallet 311 and the transmission belt 34, thereby improving the smoothness of the transmission belt 34's movement and ensuring stable conveying of the material 200. Before bending the pallet 311 into the curved section 3112, burrs are removed, and the curved section 3112 and the straight section 3111 are ground to further reduce frictional damage and improve noise reduction.
[0084] In some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, the support frame 31 includes: two support rods 312 spaced apart along the width direction of the transmission belt 34, each support rod 312 being arranged along the transmission direction X of the transmission unit 3; a connecting rod 313 connecting the two support rods 312; a pair of mounting shafts 314 mounted on the two support rods 312; and both ends of the drive shaft 32 and both ends of the driven shaft 33 being mounted on the mounting shaft 314 via bearings 3141.
[0085] The support frame 31 includes support rods 312 on both sides and connecting rods 313 connecting the support rods 312 on both sides. A mounting shaft 314 extends along the width of the transmission belt 34 and is fixedly connected to the two support rods 312. A mounting shaft 314 is provided corresponding to the drive shaft 32 and a mounting shaft 314 is provided corresponding to the driven shaft 33. The mounting shafts 314 are directly fixed to the support rods 312, thereby defining the positions of the drive shaft 32 and the driven shaft 33 that cooperate with the mounting shaft 314, improving structural accuracy.
[0086] The two ends of the drive shaft 32 are mounted on the corresponding mounting shaft 314 via bearings 3141, and the two ends of the driven shaft 33 are mounted on the corresponding mounting shaft 314 via bearings 3141, so that the drive shaft 32 and the driven shaft 33 can rotate relative to the support rod 312.
[0087] In some embodiments of this utility model, the drive shaft 32 and the driven shaft 33 are connected to the mounting shaft 314 by built-in bearings. The built-in bearings save space, have high coaxiality, and have a good lifespan.
[0088] In some embodiments of this utility model, the support frame 31 includes: a support plate 311, which is arranged along the transmission direction X of the transmission unit 3; the support plate 311 is mounted on a connecting rod 313, which supports the support plate 311; and a transmission belt 34 is an annular belt, with its upper half located above the support plate 311. Under the combined action of the support rod 312, the connecting rod 313, and the support plate 311, the transmission belt 34 is stably supported and moves stably along an annular path.
[0089] In some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, the support rod 312 is provided with a mounting groove 3123, the opening 31231 of the mounting groove is set upward, and the mounting shaft 314 is assembled in the mounting groove 3123 through the opening 31231; the transmission unit 3 also includes a pressure block 38, which is detachably mounted on the support frame 31 and sealed at the opening.
[0090] It is worth noting that the opening 31231 of the mounting groove is set upward. The opening 31231 of the mounting groove can be opened vertically upward or it can be opened at an angle to the vertical.
[0091] The mounting shaft 314 is fitted into the mounting groove 3123 through an opening, and the mounting shaft 314 can only leave the groove through the opening 31231. The direction of the opening 31231 of the mounting groove, that is, the direction from the opening to the bottom of the mounting groove 3123, is the mounting direction Y of the mounting groove. The opening 31231 of the mounting groove is oriented upward, while the tensioning force of the transmission belt 34 is in the horizontal direction. Therefore, the opening of the mounting groove 3123 can improve the arrangement stability of the mounting shaft 314 and reduce the occurrence of the mounting shaft 314 detaching from the mounting groove 3123.
[0092] The mounting shaft 314 is installed in the mounting groove 3123 through an opening. The mounting shaft 314 is locked in the mounting groove 3123 by the pressure block 38, which can improve the installation stability of the mounting shaft 314 and the support rod 312. For example, the pressure block 38 is detachably installed on the support rods 312 on both sides using bolts, which is convenient for disassembly and cleaning.
[0093] In some embodiments of this utility model, such as Figure 2 As shown, the support rod 312 is constructed as a square tube with a mounting groove 3123 on it, which can reduce the movement of the mounting shaft 314 relative to the support rod 312.
[0094] In some embodiments of this utility model, such as Figure 4 As shown, the direction from the opening to the bottom of the mounting groove 3123 is the mounting direction Y of the mounting groove; at least one mounting groove 3123 has an acute angle α between its mounting direction Y and the transmission direction X of the transmission unit 3, and the direction from the opening to the bottom of the groove is consistent with the tensioning direction of the transmission belt 34.
[0095] After the mounting shaft 314 is installed into the mounting groove 3123, the tensioning force of the transmission belt 34 is in the horizontal direction. Since the angle α between the mounting direction Y of the mounting groove and the transmission direction X of the transmission unit 3 is an acute angle, the mounting shaft 314 receives an inward pressure after being inserted into the mounting groove 3123, thereby preventing the mounting shaft 314 from coming out of the mounting groove 3123.
[0096] In some embodiments of this utility model, such as Figure 2 As shown, the support rod 312 includes a main rod 3121 and an extension rod 3122. The extension rod 3122 is adjustablely mounted on the main rod 3121 along the extension direction of the main rod 3121. One of the drive shaft 32 and the driven shaft 33 is mounted on the main rod 3121, and the other is mounted on the extension rod 3122.
[0097] By setting the extension rod 3122, the size of the support rod 312 can be increased, thereby adjusting the size of the transmission belt 34 in the transmission direction X of the transmission unit 3 to meet the conveying requirements of various materials 200, so that the analyzer 100 can be used to analyze more types of materials 200 and the analyzer 100 can be applied to a wider range of fields.
[0098] In some embodiments of this utility model, such as Figure 2 As shown, the drive shaft 32 is provided with pulleys 351 located inside the support rods 312 on both sides. The pulleys 351 are connected to the drive component 35 through a transmission structure such as a belt. The drive component 35 drives the drive shaft 32 to rotate, thereby facilitating the assembly and disassembly of the drive shaft 32 and the frame 5.
[0099] In some embodiments of this utility model, such as Figure 2 As shown, a ceramic rod anti-deviation device 39 is provided on the support rod 312.
[0100] In some embodiments of this utility model, the identification unit 4 includes at least one of the following: an ultraviolet identification component, an infrared identification component, a hyperspectral identification component, a visible light identification component, and a transmission identification component.
[0101] The ultraviolet recognition component is used to identify aging, the infrared recognition component and the hyperspectral recognition component are used to identify the material type of material 200, and the visible light recognition component is used to identify the color of material 200.
[0102] The analyzer 100 of this utility model embodiment can not only select the type of identification unit 4 according to the analysis needs, but also select the arrangement position of the identification unit 4 as needed.
[0103] In some embodiments of this utility model, such as Figure 1 and Figure 11 As shown, the identification unit 4 includes a first identification component 41, which is located above the conveyor channel 3a to identify the material 200 with the help of the background provided by the conveyor belt 34.
[0104] Optionally, the first identification component 41 may be one or more of an ultraviolet identification component, an infrared identification component, and a hyperspectral identification component.
[0105] In some embodiments of this utility model, such as Figure 1 , Figure 11 and Figure 12 As shown, the identification unit 4 includes a second identification component 42, which is set according to the material throwing route S between the transmission unit 3 and the receiving unit 2. Visible light can be set at the position where the material 200 is thrown out by the transmission belt 34 to perform multi-angle full-coverage detection and identification of the material 200.
[0106] Optionally, the second identification component 42 may be one or more of a visible light identification component and a transmission identification component.
[0107] In some embodiments of this utility model, the analyzer 100 detects a large amount of information and requires a large number of detection stations. Therefore, the detection stations can be further increased by increasing the material 200's travel path.
[0108] For example, a channel or conveyor belt 34 can be provided at the discharge port position below the receiving unit 2 to allow the material 200 to continue traveling along a predetermined path, and other identification units 4 can be added on multiple paths as needed; or, for example, two conveyor belts 34 can be used, with a visible light identification component for identifying thrown objects located at the end of the first and / or second conveyor belts 34. Thus, different material 200 conveying methods can be constructed through repeated combinations of multiple components such as the conveyor belts 34, channels, and receiving units 2, and multiple different detection positions can be set as needed.
[0109] In some specific embodiments of this utility model, the analyzer 100 is used to detect plastics, and needs to detect aging sheets, materials, light transmittance, and color, etc. An ultraviolet detection component and an infrared (hyperspectral) monitoring component can be set above the conveying channel 3a of the conveyor belt 34 to detect aging sheets and materials respectively; a visible light detection component and a background roller are set at the throwing position of the conveyor belt 34 to detect the light transmittance of the material, and then a visible light detection component is added to detect the color and other information of the material 200 thrown in the air, thereby completing the identification and analysis of material quality data.
[0110] like Figure 11 As shown, a dual-viewpoint single-path optical layout can be arranged, compatible with visible, infrared, and ultraviolet light. The plastic sorting section uses ultraviolet and infrared light for material sorting. In the plastic sorting section, multiple viewpoints can be arranged to detect color and transparency separately.
[0111] Each of the upper and lower sorting boxes can be equipped with three viewing mirrors, with different front-to-back, left-to-right, and angle positions, allowing for comprehensive inspection of material 200. Material 200 is secured with countersunk screws to improve positioning accuracy.
[0112] In some specific embodiments of this utility model, the analyzer 100 is used to detect nuts, Chinese herbal medicines, fruits and vegetables, etc. The transmission belt 34 can be set to be used only for material 200 transmission. No identification unit 4 is set above the transmission channel 3a. Then, a visible light detection component is set at the material 200 ejection position.
[0113] It is worth noting that the aforementioned visible light detection component can be equipped with two cameras on the upper and lower sides of the location where the material 200 passes, and the two cameras are staggered in the horizontal direction, thereby completing a 360-degree panoramic detection of the surface of the material 200.
[0114] In some embodiments of this utility model, such as Figure 5 As shown, the identification unit 4 further includes a light shield 43 disposed on at least one side of the material throwing path S, the light shield 43 having a light-transmitting hole 431 for the light path required by the second identification component 42.
[0115] By setting a light-shielding plate 43 and setting a light-transmitting hole 431 on the light-shielding plate 43, the path of light in the space can be controlled. One light-shielding plate 43 can process multiple light paths, saving space and facilitating installation. Furthermore, multiple through holes can be arranged on the light-shielding plate 43, and the opening size can be made at will, so as to adapt to different application scenarios.
[0116] In some embodiments of this utility model, such as Figure 6 and Figure 7 As shown, the analyzer 100 also includes a frame 5, which is the main body of the analyzer 100. The feeding unit 1, receiving unit 2, transmission unit 3, and identification unit 4 are all integrated and installed on the frame 5.
[0117] In some embodiments of this utility model, such as Figures 6-8 As shown, the analyzer 100 also includes other components mounted on the frame 5 to enhance the functionality of the analyzer 100.
[0118] Optionally, a printer 51 is mounted on frame 5 to print test results.
[0119] Alternatively, an electric dust removal device 52 may be installed on the frame 5 to adapt to conditions without an air source.
[0120] In some embodiments of this utility model, such as Figure 6 and Figure 7 As shown, the analyzer 100 also includes at least one of a window 6 and a display 7, the display 7 being electrically connected to the identification unit 4, and the window 6 and the display 7 being mounted on the frame 5.
[0121] By setting window 6, the internal structure of the analyzer 100 can be directly observed, making it easier to detect internal damage or malfunctions of the analyzer 100 in a timely manner; by setting display 7, the identification results of the analyzer 100 can be displayed intuitively.
[0122] In some embodiments of this utility model, such as Figure 1 and Figure 11 As shown, the feeding unit 1 includes a feeding hopper 11 and at least one vibrating feeder 12, which is located between the feeding hopper 11 and the drive belt 34.
[0123] Material 200 is fed into the feed hopper 11 and then sent to the transmission belt 34 by the vibrating feeder 12. By setting the vibrating feeder 12, the material 200 can fall onto the transmission belt 34 more evenly and is easier to identify.
[0124] In some embodiments of this utility model, such as Figure 1 As shown, the feeding unit 1 includes a feeding hopper 11 and a vibrating feeder 12. By setting the vibrating feeder 12, the material 200 can fall onto the belt more evenly and is easier to identify.
[0125] In some other embodiments of this utility model, the feeding unit 1 includes two feeding hoppers 11 and two vibrating feeders 12. The feeding hoppers 11 and the vibrating feeders 12 are arranged in a one-to-one correspondence. After the material 200 enters one feeding hopper 11, it falls onto the first-stage vibrating feeder 12. Then, the material 200 enters the next hopper and falls onto the second-stage vibrating feeder 12, and finally falls onto the transmission belt 34. Arranging two stages of vibrating feeders 12 can make the material 200 fall onto the belt more evenly and make it easier to identify.
[0126] In some embodiments of this utility model, the feed hopper 11 has a structure that is wider at the top and narrower at the bottom, which saves space; the feed hopper 11 has a weighing function, which can determine the total weight of the test material 200.
[0127] In some embodiments of this utility model, such as Figure 1 and Figure 12 As shown, the feeding unit 1 also includes an acceleration guide plate 13. One end of the acceleration guide plate 13 is set at the outlet of the vibrating feeder 12, and the other end extends above the transmission belt 34. The acceleration guide plate 13 is an arc-shaped plate to guide the material 200.
[0128] By setting the acceleration guide plate 13, the material 200 is accelerated quickly over a short distance, matching the speed of the transmission belt 34, so as to reach relative stillness as soon as possible and improve the conveying reliability of the material 200.
[0129] In some specific embodiments of this utility model, the speed of the transmission belt 34 can reach 1.5m / s.
[0130] In some embodiments of this utility model, such as Figure 1 and Figure 9 As shown, the analyzer 100 also includes at least one of a metal detection device 9 and a rejection device 8, which are located at the receiving unit 2.
[0131] The metal content in the material 200 can be detected by setting the metal detection device 9, or whether the material 200 is mixed with metal impurities; the impurities can be removed before the receiving unit 2 by setting the rejection device 8.
[0132] In some embodiments of this utility model, such as Figure 10 As shown, the rejection device 8 includes an air rejection device 81. The air rejection device 81 has a simple and compact structure, is easy to control, and is suitable for rapid deployment in small spaces.
[0133] The air rejection device 81 is equipped with nozzles 811. The gas flow is controlled by a solenoid valve to supply air to the nozzles 811. The nozzles 811 form a fan-shaped air jet area, which blocks the material 200 from advancing and achieves the sorting effect. Compared with the spray valve, it is simple to control and has a smaller size. Compared with the flap structure, it is simpler and carries out less material.
[0134] In some embodiments of this utility model, such as Figures 13-15 As shown, the identification unit 4 includes an infrared light source device 46 and an ultraviolet lamp device 47. An air return vent 53 is formed on the frame 5. The infrared light source device 46 and the ultraviolet lamp device 47 are respectively equipped with an infrared cooling fan 461 and an ultraviolet cooling device 471 to accelerate heat dissipation. The arrow lines in the figure indicate the airflow direction, which improves the working stability of the identification unit 4.
[0135] The structure and working process of the material dispenser of two specific embodiments of this utility model are described below with reference to the accompanying drawings.
[0136] In Example 1, the analyzer 100 is used for plastic detection. The feeding unit 1 includes two feeding hoppers 11 and two vibrating feeders 12. The arrangement of two-stage vibrating feeders 12 makes the material 200 fall more evenly onto the belt, which is more conducive to identification. An acceleration guide plate 13 is set below the secondary vibrating feeder 12, which allows the material 200 to accelerate rapidly over a short distance, matching the speed of the transmission belt 34. The transmission belt 34 is selected as a high-speed, small-size belt, with a speed of up to 1.5 m / s. The drive shaft 32 of the transmission belt 34 has a diameter of 30 mm. The transmission belt 34 is black, which is beneficial for composite spectral identification.
[0137] Plastics need to be tested for aging, material, light transmittance and color, etc. An ultraviolet detection component is set above the conveyor channel 3a of the transmission belt 34 to detect the aging sheets, and an infrared recognition component or a hyperspectral recognition component is set to detect the material 200.
[0138] A visible light recognition component is installed at the ejection position of the conveyor belt 34, along with a background roller and a light source 44. This component detects information such as color of the material 200 ejected into the air. The background roller is white for easy recognition, and it is positioned as close as possible to the material 200 and the conveyor belt to minimize shadows. The light source 44 is positioned close to the camera's optical axis, and the angle between the light source 44 and the visible light recognition component is minimized to further reduce shadows. A transmission recognition component is also installed at the ejection position of the conveyor belt 34, in conjunction with a background light source 45, to detect the light transmittance of the material.
[0139] A light-shielding plate 43 is also provided at the ejection position of the conveyor belt 34 to block stray light. The visible light recognition component, the light source 44, and the background light source 45 are located above the ejection position of the conveyor belt 34, and the transmission recognition component is located below the ejection position of the conveyor belt 34 and directly opposite the background light source 45. There are two light-shielding plates 43, one above and one below the ejection position of the conveyor belt 34. The upper light-shielding plate 43 separates the visible light recognition component, the light source 44, and the background light source 45 from the ejection position of the conveyor belt 34; the lower light-shielding plate 43 is located between the ejection position of the conveyor belt 34 and the transmission recognition component.
[0140] The light-transmitting hole 431 on the upper side of the light-shielding plate 43 includes an illumination grating through which light from the light source 44 can pass, and a background grating through which light from the background light source 45 can pass; the light-transmitting hole 431 on the lower side of the light-shielding plate 43 includes a background grating through which light from the background light source 45 can pass.
[0141] The illumination light emitted by light source 44 passes through an illumination grating and illuminates the ejection position of the conveyor belt 34. After being reflected by the material 200, it passes through the illumination grating and is directed towards the visible light recognition component. The visible light recognition component collects clear image information of the material 200. The illumination grating controls the path of light in space, ensuring that the illumination light is stably directed towards the visible light recognition component and blocking interfering stray light. This process reduces stray light other than the illumination light entering the visible light recognition component, improving the accuracy of the image information acquired by the visible light recognition component. In this way, only a light-shielding plate 43 is needed to process most of the light paths, saving space and facilitating installation.
[0142] The background light emitted by the background light source 45 illuminates the conveyor belt 34 at its ejection position after passing through a background grating. It then continues through another light-shielding plate 43, where it illuminates the transmission recognition component, which captures the background light. The background grating controls the light path in space, ensuring stable illumination of the transmission recognition component while blocking the illumination light from the light source 44 and other stray light. This light path processing reduces stray light entering the transmission recognition component, improving the accuracy of the image information acquired by the component. Thus, only two light-shielding plates 43 are needed to process most of the light paths, saving space and facilitating installation.
[0143] It is worth noting that one or more of the background grating and illumination grating can be combined to allow different light rays to pass through together. A single light-shielding plate 43 can handle most light paths, saving space and facilitating installation; furthermore, multiple gratings can be arranged on the light-shielding plate 43, and the opening size can be freely manufactured to adapt to different application scenarios. It is also worth noting that the area of the light-shielding plate 43 that blocks light also has a light-absorbing function, not only preventing light from passing through but also preventing light reflection to the visible light recognition component, thereby reducing stray light.
[0144] The light-shielding plate 43 can also be multi-layered. There may still be some stray light in the optical path system. By setting multiple light-shielding plates 43, interference to the camera can be further eliminated, and the accuracy of the image information acquired by the camera can be further improved.
[0145] Example 2, as Figure 1 As shown, the analyzer 100 is used to detect nuts, Chinese herbal medicines, fruits and vegetables, etc. The transmission belt 34 is selected to be a textured belt, which can improve the stability of material transmission 200.
[0146] A high-definition camera is installed above the conveyor channel 3a of the transmission belt 34 to select the shape and color of the material 200; an infrared recognition component or a hyperspectral recognition component is installed to detect the material of the material 200.
[0147] Then, a visible light detection component and a transmission recognition component are set at the material 200 ejection position. The four cameras of the visible light detection component and the transmission recognition component detect one point, ensuring no blind spots in the recognition. Multiple light sources 44 are set to make the surface brightness of the material 200 uniform, and a background light source 45 is set to facilitate recognition. The background color can be changed according to the type of material 200.
[0148] A light shield 43 is also provided at the ejection position of the transmission belt 34 to block stray light.
[0149] There are multiple visible light recognition components, transmission recognition components, light sources 44 and background light sources 45, and they are set on both the upper and lower sides of the ejection position of the conveyor belt 34. There are two light shields 43, which are placed on the upper and lower sides of the ejection position of the conveyor belt 34 respectively. The arrangement of the light shields 43 on the upper and lower sides separates the visible light recognition components, transmission recognition components, light sources 44, background light sources 45 and the ejection position of the conveyor belt 34.
[0150] The light-transmitting hole 431 on the light-shielding plate 43 includes an illumination grating through which light from the light source 44 can pass, and a background grating through which light from the background light source 45 can pass.
[0151] The illumination light emitted by light source 44 passes through an illumination grating and illuminates the ejection position of the conveyor belt 34. After being reflected by the material 200, it passes through the illumination grating and is directed towards the visible light recognition component. The visible light recognition component collects clear image information of the material 200. The illumination grating controls the path of light in space, ensuring that the illumination light is stably directed towards the visible light recognition component and blocking interfering stray light. This process reduces stray light other than the illumination light entering the visible light recognition component, improving the accuracy of the image information acquired by the visible light recognition component. In this way, only a light-shielding plate 43 is needed to process most of the light paths, saving space and facilitating installation.
[0152] The background light emitted by the background light source 45 illuminates the conveyor belt 34 at its ejection position after passing through a background grating. It then continues through another light-shielding plate 43, where it illuminates the transmission recognition component, which captures the background light. The background grating controls the light path in space, ensuring stable illumination of the transmission recognition component while blocking the illumination light from the light source 44 and other stray light. This light path processing reduces stray light entering the transmission recognition component, improving the accuracy of the image information acquired by the component. Thus, only two light-shielding plates 43 are needed to process most of the light paths, saving space and facilitating installation.
