This is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0067] In addition, if terms such as "first", "second", etc. are only used for distinguishing descriptions, they cannot be understood as indicating or implying relative importance.

[0068] It should be noted that, without conflict, the features in the embodiments of the present invention can be combined with each other.

[0069] Please refer to Figures 1 to 2 , this embodiment provides a fruit and vegetable detection device 10, which is applied to detect the surface image information of fruits and vegetables, and is particularly suitable for the detection of fruits. The fruit and vegetable detection device 10 can effectively detect the image information at the bottom of fruits and vegetables, which is beneficial to the sorting and screening of fruits and vegetables in subsequent processes.

[0070] The fruit and vegetable detection device 10 provided by the present invention includes a conveying track 100, an image acquisition machine, a rotating mechanism 300, a lifting mechanism 400, an adsorption mechanism 500, a mounting frame 600, and a driving mechanism 700.

[0071] In this embodiment, the mounting frame 600 has a mounting platform. The conveying track 100, the rotating mechanism 300, and the image acquisition mechanism 200 are all mounted on the mounting platform of the mounting frame 600. The adsorption mechanism 500 and the driving mechanism 700 are mounted below the mounting platform of the mounting frame 600. The driving mechanism 700 is used to drive the conveying track 100 and the rotating mechanism 300 to move.

[0072] In practical applications, the fruits and vegetables are transported to the mounting platform on the mounting frame 600 through the conveying track 100, and the fruits and vegetables are jointly transported to the image acquisition area 240 through the rotating mechanism 300, the lifting mechanism 400, and the adsorption mechanism 500, so as to collect the image information at the bottom of the fruits and vegetables through the image acquisition mechanism 200. After the image information is collected, the fruits and vegetables are transported to subsequent detection or sorting equipment through the conveying track 100. The collected image information is used to grade the quality of the fruits and vegetables to facilitate the sorting and screening of the fruits and vegetables in subsequent processes.

[0073] It should be noted that to prevent damage to fruits and vegetables during transportation, the fruits and vegetables are usually placed in fruit cups or fruit plates, and then the fruit plates are placed on the conveying track 100.

[0074] Further, the conveying track 100 includes a detection track 110, a feeding track 120, and a discharging track 130. One end of the detection track 110 is connected to the feeding track 120, and the other end is connected to the discharging track 130.

[0075] In this embodiment, both the feeding track 120 and the discharging track 130 are straight lines, and fruits and vegetables are conveyed on the feeding track 120 and the discharging track 130 by a conveyor belt; the detection track 110 is semi-circular, and fruits and vegetables are conveyed on the detection track 110 by a rotating mechanism 300. The feeding track 120, the detection track 110, and the discharging track 130 are connected in sequence to form a U shape, so that the floor area of the fruit and vegetable detection device 10 is small, which is convenient for placing the fruit and vegetable detection device 10.

[0076] Specifically, the detection track 110 includes a first detection track 111, a second detection track 112, and a third detection track 113 that are connected in sequence. The first detection track 111 is connected to the feeding track 120, and the third detection track 113 is connected to the discharging track 130. The image acquisition mechanism 200 is disposed on the second detection track 112 and forms an image acquisition area 240 at the detection track 110.

[0077] In practical applications, after the fruits and vegetables enter the detection track 110, the adsorption mechanism 500 adsorbs the fruits and vegetables. The lifting mechanism 400 lifts the fruits and vegetables when the adsorption mechanism 500 adsorbs the fruits and vegetables, and drives the lifted fruits and vegetables to the image acquisition area 240 under the drive of the rotating mechanism 300, so as to collect the bottom image information of the fruits and vegetables through the image acquisition mechanism 200.

[0078] Please refer to Figures 1 to 3 , the image acquisition mechanism 200 includes a plurality of image acquirers 210. The plurality of image acquirers 210 are all disposed on both sides of the detection track 110 and face the bottom of the fruits and vegetables in the image acquisition area 240.

[0079] In this embodiment, by simultaneously setting a plurality of image acquirers 210 to perform multi-directional image acquisition of the bottom of the fruits and vegetables, the accuracy of the acquired information can be improved.

[0080] Specifically, the image acquirer 210 is usually a camera, and the number of cameras is usually set to three. One camera is disposed inside the detection track 110, and two cameras are disposed outside the detection track 110. The included angle between the camera inside the detection track 110 and any one of the two cameras outside the detection track 110 is 130°. It can be understood that the number of cameras and the included angle between the cameras can also be other settings, which are not specifically limited herein.

[0081] Further, the image acquisition mechanism 200 further includes a first light-shielding baffle 220 and a second light-shielding baffle 230, and a plurality of image collectors 210 are respectively arranged on the first light-shielding baffle 220 and the second light-shielding baffle 230.

[0082] In this embodiment, both the first light-shielding baffle 220 and the second light-shielding baffle 230 are arc-shaped, so as to form a hemispherical image acquisition area 240 in the area between the first light-shielding baffle 220 and the second light-shielding baffle 230. LED light groups 250 are arranged at the tops of both the first light-shielding baffle 220 and the second light-shielding baffle 230. The light of the LED light groups 250 irradiates on the inner walls of the arc-shaped first light-shielding baffle 220 and the second light-shielding baffle 230 and is diffusely reflected to the surface of the fruits and vegetables, so as to improve the accuracy and clarity of the image information collected by the image acquisition mechanism 200. In addition, the first light-shielding baffle 220 and the second light-shielding baffle 230 can also play a role in protecting the fruits and vegetables, and avoid the fruits and vegetables located in the image acquisition area 240 being affected by other factors, resulting in inaccurate image information collected by the image acquisition mechanism 200.

[0083] Specifically, the first light-shielding baffle 220 and the second light-shielding baffle 230 are arranged on both sides of the detection track 110. Among them, the first light-shielding baffle 220 is arranged on the inner side of the detection track 110, and one camera is arranged at the first light-shielding baffle 220; the second light-shielding baffle 230 is arranged on the outer side of the detection track 110, and two cameras are arranged at the second light-shielding baffle 230.

[0084] Please continue to refer to Figures 4 to 5 , the rotation mechanism 300 is arranged close to the detection track 110, and the rotation mechanism 300 is used to drive the fruits and vegetables to move along the detection track 110.

[0085] In this embodiment, the rotation mechanism 300 is arranged above the detection track 110, and the circumferential line where the detection track 110 is located coincides with the outer circumferential line of the rotating part of the rotation mechanism 300.

[0086] In this embodiment, the rotation mechanism 300 includes a rotating shaft 310, a first turntable 320, a second turntable 330 and a guide member 340. The rotating shaft 310 is rotatably arranged on the mounting frame 600 and is connected to the first turntable 320 and the second turntable 330. The guide member 340 is connected to the second turntable 330 through a connecting rod (not shown in the figure) and rotates along with the second turntable 330.

[0087] In this embodiment, the rotating shaft 310 is mounted on the mounting frame 600 through a bearing (not shown in the figure). The first turntable 320 and the second turntable 330 are driven by the rotating shaft 310 to rotate around the rotating shaft 310, so that the lifting mechanism 400 provided on the rotating mechanism 300 rotates following the rotating mechanism 300. The fruits and vegetables are adsorbed by the adsorption mechanism 500 connected to the lifting mechanism 400, thereby realizing the conveyance of the lifted fruits and vegetables to the image acquisition area 240 and performing image acquisition on the bottom of the fruits and vegetables.

[0088] Further, an inner concave portion 341 is provided on the outer periphery of the guiding member 340. The size of the inner concave portion 341 is larger than the size of the fruits and vegetables. One inner concave portion 341 accommodates one fruit or vegetable, so as to achieve the purpose of separating multiple fruits and vegetables. The guiding member 340 is driven by the second turntable 330 to rotate, so that the inner concave portion 341 drives the fruits and vegetables to move along the detection track 110.

[0089] Please continue to refer to Figures 5 to 7 , the lifting mechanism 400 is provided on the rotating mechanism 300 and can rotate following the rotating mechanism 300. The adsorption mechanism 500 is connected to the lifting mechanism 400.

[0090] It should be noted that the lifting mechanism 400 is mounted on the first turntable 320 and the second turntable 330, and the number of the lifting mechanisms 400 is multiple. The multiple lifting mechanisms 400 are arranged in a ring on the outer peripheral part of the first turntable 320 and the second turntable 330. The number of the inner concave portions 341 of the guiding member 340 is also multiple. The multiple inner concave portions 341 correspond to the multiple lifting mechanisms 400 one by one.

[0091] Specifically, the number of the inner concave portions 341 and the number of the lifting mechanisms 400 are both 16.

[0092] Further, the lifting mechanism 400 includes a sliding rod 410, a first sliding member 420, a limiting member 430, a mounting member 440, a lifting track 450, an elastic member 460, and a fixing block 470.

[0093] In this embodiment, the sliding rod 410 passes through the first turntable 320 and the second turntable 330 and can be slidably engaged with the first turntable 320 and the second turntable 330. Among them, one end of the sliding rod 410 extending out of the first turntable 320 is connected to the limiting member 430, and one end of the sliding rod 410 extending out of the second turntable 330 is connected to the mounting member 440. Both the limiting member 430 and the mounting member 440 play a role in preventing the sliding rod 410 from detaching from the first turntable 320 and the second turntable 330, improving the structural stability of the lifting mechanism 400.

[0094] In this embodiment, a first sliding member 420 is provided on the mounting member 440. The lifting track 450 is fixedly mounted on the mounting frame 600 and is located below the second turntable 330. The sliding member can be slidably engaged with the lifting track 450.

[0095] Specifically, the sliding rod 410 drives the first sliding member 420 to move along the lifting track 450 under the drive of the first turntable 320 and the second turntable 330, and drives the sliding rod 410 to lift relative to the first turntable 320 and the second turntable 330 under the limitation of the lifting track 450.

[0096] It should be noted that the lifting track 450 is a circular track, and the lifting track 450 includes continuous first lifting track 451, second lifting track 452, third lifting track 453 and fourth lifting track 454, and the fourth lifting track 454 is connected to the first lifting track 451. Among them, the first lifting track 451 and the third lifting track 453 are concave, and adjacent lifting tracks 450 are connected by smooth and inclined tracks. The first lifting track 451, the second lifting track 452 and the third lifting track 453 correspond to the first detection track 111, the second detection track 112 and the third detection track 113 one by one.

[0097] In practical applications, when the first sliding member 420 slides in the first lifting track 451, the lifting mechanism 400 is in a descending state to adsorb fruits and vegetables on the first detection track 111 through the adsorption mechanism 500; when the first sliding member 420 slides from the first lifting track 451 to the second lifting track 452, the lifting mechanism 400 rises to lift the fruits and vegetables, so as to collect the bottom image information of the fruits and vegetables through the image acquisition mechanism 200; when the first sliding member 420 slides from the second lifting track 452 to the third lifting track 453, the lifting track 450 descends and the fruits and vegetables are put down through the adsorption mechanism 500; the first sliding member 420 slides from the third lifting track 453 to the fourth lifting track 454 and then slides from the fourth lifting track 454 to the first lifting track 451, and so on in a cycle.

[0098] Please continue to refer to Figures 8 to 10 , the elastic member 460 is sleeved outside the sliding rod 410 and is located between the first turntable 320 and the second turntable 330. The fixing block 470 is fixedly installed on the sliding rod 410. One end of the elastic member 460 is connected to the first turntable 320, and the other end is connected to the fixing block 470.

[0099] In this embodiment, when the first slider 420 slides to the second lifting track 452 and the fourth lifting track 454, the sliding rod 410 drives the fixed block 470 to rise, and the elastic member 460 is compressed under the action of the fixed block 470; when the first slider 420 slides from the second lifting track 452 to the third lifting track 453 or from the fourth lifting track 454 to the first lifting track 451, the elastic restoring force generated by the elastic member 460 acts on the fixed block 470 on the sliding rod 410, so that the sliding rod 410 descends, and the first slider 420 is always located on the lifting track 450, thereby ensuring the normal operation of the lifting mechanism 400.

[0100] In addition, since the number of the lifting mechanisms 400 is multiple, the multiple lifting mechanisms 400 drive fruits and vegetables to the image acquisition area 240 for image acquisition in sequence through the adsorption mechanism 500, improving the automation performance and detection efficiency of the fruit and vegetable detection device 10.

[0101] Furthermore, the adsorption mechanism 500 includes a blower 510, a buffer chamber 520, an air path slip ring 530, a plurality of air valves 540, an adsorbent 550, a valve track 560, and an air path pipe (not shown in the figure).

[0102] In this embodiment, the blower 510, the buffer chamber 520, the air path slip ring 530, the air valve 540, and the adsorbent 550 are sequentially connected through the air path pipe. The number of the adsorbents 550 is multiple, and the multiple adsorbents 550 are correspondingly arranged at one ends of the multiple sliding rods 410. A negative pressure is provided to the multiple adsorbents 550 through the blower 510, so as to adsorb fruits and vegetables to lift the fruits and vegetables.

[0103] Specifically, the blower 510, the buffer chamber 520, and the valve track 560 are all arranged on the mounting frame 600, and the numbers of the blower 510 and the buffer chamber 520 are both two. The two blowers 510 and the two buffer chambers 520 are correspondingly connected one by one. The air path slip ring 530 and the air valve 540 are both arranged on the lifting mechanism 400, and the adsorbent 550 is arranged on the mounting member 440.

[0104] It should be noted that in other embodiments of the present invention, the blower 510 can be directly connected to the adsorbent 550 through the air path pipe. That is to say, the adsorption mechanism 500 includes at least the blower 510, the adsorbent 550, and the air path pipe, and other components can be added or deleted according to actual situations, which are not specifically limited herein.

[0105] Further, the air path slip ring 530 includes a fixed end 531 and a rotating end 532, and the fixed end 531 and the rotating end 532 can rotate relative to each other. The fixed end 531 is fixedly connected to a cross beam (not shown in the figure) on the mounting frame 600, and the rotating end 532 is connected to the first turntable 320 and can rotate with the first turntable 320. Thus, the air path slip ring 530 realizes the connection between the blower 510 fixedly connected to the mounting frame 600 and the suction attachment 550 that follows the rotation mechanism 300 to rotate.

[0106] In this embodiment, the fixed end 531 is provided with a plurality of first air ports 533, and the plurality of first air ports 533 are all communicated with the blower 510 through the buffer chamber 520. The rotating end 532 is provided with a plurality of second air ports 534, and the plurality of second air ports 534 are in one-to-one communication with the plurality of suction attachments 550. Among them, the plurality of first air ports 533 and the plurality of second air ports 534 are in one-to-one corresponding communication.

[0107] In this embodiment, the buffer chamber 520 includes a third air port 521 and a plurality of fourth air ports 522. The third air port 521 is communicated with the blower 510, and the plurality of fourth air ports 522 are in one-to-one corresponding communication with the plurality of first air ports 533. The blower 510 and the air path slip ring 530 are communicated through the blower 510, which can make the flow of gas more uniform, thereby improving the adsorption effect of the adsorption mechanism 500.

[0108] Specifically, the number of both the first air ports 533 and the second air ports 534 is 16, the number of buffer chambers 520 is 2, and one buffer chamber 520 is provided with 8 fourth air ports 522.

[0109] Further, the air vent valve 540 is arranged on the first turntable 320 and rotates with the first turntable 320. One ends of the plurality of air vent valves 540 are in one-to-one corresponding communication with the plurality of second air ports 534, and the other ends are in one-to-one corresponding communication with the plurality of suction attachments 550.

[0110] Specifically, the air vent valve 540 is a mechanical roller type two-position five-way solenoid valve, and the air path pipeline can be controlled to be interrupted or conducted through the air vent valve 540. The number of both the air vent valves 540 and the lifting mechanism 400 is 16.

[0111] It should be noted that the number of slide rods 410 in the lifting mechanism 400 is two, and one of the slide rods 410 is an air path pipeline. The slide rod 410 is connected to the suction attachment 550 through an air pipe joint (not shown in the figure) so that the air vent valve 540 and the suction attachment 550 are communicated.

[0112] Further, the valve track 560 is fixedly installed on the mounting frame 600, and the air vent valve 540 is located between the valve track 560 and the second turntable 330. The air vent valve 540 has a second sliding member 541, and the second sliding member 541 slides on the valve track 560 driven by the first turntable 320.

[0113] The valve track 560 includes a first valve track 561 and a second valve track 562. The ventilation valve 540 is turned on when the second slider 541 slides on the first valve track 561, and the ventilation valve 540 is turned off when the second slider 541 slides on the second valve track 562.

[0114] In this embodiment, the first valve track 561 protrudes relative to the second valve track 562. In other words, the distance between the first valve track 561 and the second turntable 330 is less than the distance between the second valve track 562 and the second turntable 330. When the second slider 541 slides to the first valve track 561, the ventilation valve 540 presses the second slider 541 to open the valve of the ventilation valve 540, thereby realizing the adsorption of fruits and vegetables by the adsorbent 550; when the second slider 541 slides to the second valve track 562, the ventilation valve 540 interrupts the valve of the ventilation valve 540 through the second slider 541, thereby realizing that the adsorbent 550 stops adsorbing fruits and vegetables to put down the fruits and vegetables. Therefore, through the cooperation of the ventilation valve 540 and the valve track 560, the effect of automatically opening or interrupting the ventilation valve 540 is achieved, improving the automation degree of the fruit and vegetable detection device 10, and thus improving the detection efficiency.

[0115] Furthermore, the driving mechanism 700 is used to drive the rotation of the rotating shaft 310, drive the feeding track 120 to move towards the detection track 110, and drive the discharging track 130 to move away from the detection track 110.

[0116] In this embodiment, the driving mechanism 700 includes a motor 710 and a commutator 720. The output end of the motor 710 is connected to the rotating shaft 310 to drive the rotation, and the motor 710 is connected to the feeding track 120 and the discharging track 130 through the commutator 720.

[0117] It should be noted that both the feeding track 120 and the discharging track 130 are composed of a sprocket (not shown in the figure) and a conveyor belt (not shown in the figure). The motor 710 is connected to the sprocket of the feeding track 120 through a steering gear to drive the conveyor belt to move through the sprocket; the motor 710 is connected to the sprocket of the discharging track 130 through a steering gear to drive the conveyor belt to move through the sprocket, thereby realizing the high-efficiency transportation of fruits and vegetables.

[0118] Finally, it should be noted that the fruits and vegetables are transported to the detection track 110 through the feeding track 120, and the fruits and vegetables pass through the first detection track 111, the second detection track 112, and the third detection track 113 through the guide member 340.

[0119] When fruits and vegetables enter the first detection track 111, the lifting mechanism 400 descends along the first lifting track 451. Meanwhile, the adsorption mechanism 500 passes through the first valve track 561 to conduct the ventilation valve 540. At this time, the lifting mechanism 400 in the descending state adsorbs the fruits and vegetables through the adsorbent 550.

[0120] When fruits and vegetables enter the second detection track 112, the lifting mechanism 400 ascends along the second lifting track 452 to lift the fruits and vegetables adsorbed by the adsorption mechanism 500. The adsorption mechanism 500 remains on the first valve track 561 to continuously adsorb the fruits and vegetables. At this time, the lifted fruits and vegetables enter the image acquisition area 240, and the image information of the bottom of the fruits and vegetables is collected by the image acquisition mechanism 200 at the center of the image acquisition area 240.

[0121] When fruits and vegetables enter the third detection track 113, the lifting mechanism 400 descends along the third lifting track 453 to lower the fruits and vegetables. Meanwhile, the adsorption mechanism 500 passes through the second valve track 562 to disconnect the ventilation valve 540 to stop adsorbing the fruits and vegetables. At this time, the fruits and vegetables are transported to the downstream process through the discharge track 130, thus completing the image acquisition of the fruits and vegetables.

[0122] In summary, the fruit and vegetable detection device 10 provided by the embodiment of the present invention transports fruits and vegetables to the detection track 110 through the transport track 100, and jointly transports the fruits and vegetables to the image acquisition area 240 through the rotation mechanism 300, the lifting mechanism 400, and the adsorption mechanism 500, realizing the effective acquisition of the image information of the bottom of the fruits and vegetables by the image acquisition mechanism 200. Therefore, the fruit and vegetable detection device 10 provided by the present invention has a high degree of automation, high image acquisition efficiency, and accurate acquired image information.

Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention.
