Description

Technical Field

[0001] The present invention relates to the technical field of apple identification, and more particularly, to an apple quality identification device. Background Art

[0002] Before entering the market, apples undergo a rigorous identification process to ensure their quality. Ultraviolet light technology is widely used to identify apple quality. With its unique advantages, it can effectively detect subtle flaws on the apple's skin. Crucially, adverse factors such as microbial contamination or pesticide residues exhibit unique fluorescence or specific spectral absorption characteristics under UV light, allowing for precise identification. Therefore, UV light technology not only reveals surface flaws on apples but also excels at identifying microbial contamination or pesticide residues, ensuring the safety and high quality of apples.

[0003] The typical approach is to place apples on a testing tray and then conduct the inspection using a UV detector. However, the placement of the apples on the testing tray can reduce the accuracy of the inspection. The shape, specifications, and size of the testing tray can interfere with the uniformity and reflection of the UV light. Furthermore, the areas where the testing tray contacts the apples are obscured by the tray, preventing them from being directly observed or exposed to UV light. Summary of the Invention

[0013] The beneficial effects of the present invention compared with the prior art are:

[0014] (1) After the rubber ring and rubber cylinder of the present invention clamp the apple together, the motor 1 is continuously operated, the top shaft slides in the screw rod, the spring 2 is compressed, and then the roller rolls from the upper plane of the bracket to the inclined surface of the inclined block, driving the flat plate to slide upward. Therefore, the rubber ring and rubber cylinder clamp and lift the apple, so that the apple is separated from the detection plate, avoiding the detection plate from blocking the apple, and the contact position between the detection apple and the detection plate can be identified.

[0015] (2) After the flat plate of the present invention slides upward, the closing block continues to move toward the round block, the cross table is inserted into the cross slot, the square shaft slides in the square cavity, and then the screw rod is detached from the vertical plate, and the light rod enters the threaded hole of the vertical plate.

[0016] (3) The slide of the present invention carries the L-shaped insert plate and contacts the conical surface of the conical shell, driving the conical shell and the top shaft to move synchronously toward the inside of the screw rod, and the rubber ring is separated from the apple. Therefore, the rubber ring does not contact the apple during the descent process, thereby preventing the rubber ring from scratching the surface of the apple.

[0017] (4) The two plywood sheets of the present invention hold the unqualified apples and move them toward the opening of the temporary cavity. When the apples move to the top of the temporary cavity opening, the end circular plate contacts the inclined surface of the wedge block, and the wedge block drives the end circular plate and the slide bar to move outward. The two plywood sheets release the apples, and the unqualified apples fall into the temporary cavity. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Example: See Figure 1-8Structural schematic diagram, the present invention provides the following technical solutions: an apple quality identification device, including a bottom plate 1, a bracket 2 is provided above the bottom plate 1, a flat plate 3 is provided above the bracket 2 to slide in the vertical direction, a slide seat 4 is provided above the flat plate 3 to slide in the horizontal direction, a motor 5 is provided above the slide seat 4, the ends of the rotating shaft of the motor 5 are connected with a polished rod 6 and a screw rod 7 in sequence, a vertical plate 8 is provided above the flat plate 3, and the screw rod 7 forms a threaded fit with the vertical plate 8, a spring 9 is provided on the outside of the polished rod 6, and one end of the spring 9 is connected to the polished rod 6; a top shaft 10 is provided on the end of the screw rod 7 to slide, and the screw rod 7 and the top shaft 10 form a rotating shaft. In coordination, the outer sleeve of the top shaft 10 is provided with a spring 2 11, the two ends of the spring 2 11 are respectively connected to the ends of the screw rod 7 and the top shaft 10, and the end of the top shaft 10 is provided with a rubber ring 12 for clamping the apple 13; a support rod 14 extending to the bottom of the flat plate 3 is provided below the slide 4, and the end of the support rod 14 is rotatably provided with a roller 15 that contacts the upper plane of the bracket 2, and the upper plane of the bracket 2 is provided with an inclined block 16 for driving the roller 15 to move; a sub-frame 17 is provided below the vertical plate 8, and the sub-frame 17 is slidably provided on the bracket 2, and the upper end of the sub-frame 17 is rotatably provided with a rubber cylinder 18 for clamping the apple 13, and the rubber cylinder 18 is coaxial with the rubber ring 12.

[0029] Specifically, when motor 15 is started, it drives polished rod 6 and screw rod 7 to rotate. Due to the interaction between screw rod 7 and vertical plate 8, motor 15 and slide 4 move toward apple 13. Simultaneously, top shaft 10 and rubber ring 12 also move toward apple 13. After rubber ring 12 contacts apple 13, it pushes apple 13 toward rubber cylinder 18. Therefore, rubber ring 12 and rubber cylinder 18 jointly clamp apple 13. During this process, roller 15 rolls on the upper surface of bracket 2. Continuous operation of motor 15 causes top shaft 10 to slide within screw rod 7, compressing spring 2 11. Subsequently, roller 15 rolls from the upper surface of bracket 2 to the inclined surface of inclined block 16, driving plate 3 to slide upward. Therefore, rubber ring 12 and rubber cylinder 18 clamp and lift apple 13.

[0030] Two support plates 19 are provided above the base plate 1, and the two rotating shafts of the transmission mechanism 20 are respectively rotated on the two support plates 19. A motor 21 is provided on one support plate 19, and the rotating shaft of the motor 21 is connected to a rotating shaft of the transmission mechanism 20. A plurality of inspection trays 22 for placing apples 13 are evenly provided on the transmission belt of the transmission mechanism 20.

[0031] Specifically, the transmission mechanism 20 consists of two rotating shafts and a transmission belt. The transmission belt of the transmission mechanism 20 is wound on the two rotating shafts. Motor 21 drives one rotating shaft of the transmission mechanism 20 to rotate. The rotating shaft of the transmission mechanism 20 drives the transmission belt of the transmission mechanism 20 to rotate synchronously. Therefore, the transmission mechanism 20 drives the inspection disk 22 to operate, and the apple 13 to be inspected is placed on the inspection disk 22. The inspection disk 22 sends the apple 13 to be inspected between the rubber ring 12 and the rubber cylinder 18.

[0032] A box body 23 is provided above the bottom plate 1 , and a detection device 24 for detecting the apple 13 is provided above the box body 23 . Optionally, the detection device 24 is a detection device using the principle of ultraviolet rays.

[0033] Taking into account that when the detection device 24 identifies the apple 13, in order to make the identification clearer, the apple 13 needs to be rotated, a circular cavity 701 and a square cavity 702 are continuously provided in the screw rod 7, and a round block 25 is slidingly provided in the circular cavity 701, and the end face of the round block 25 is provided with a cross groove 2501, and a square shaft 26 is vertically provided on the end face of the round block 25 facing away from the cross groove 2501, and the square shaft 26 is slidingly provided in the square cavity 702, and a spring three 27 is provided on the outside of the square shaft 26, and the two ends of the spring three 27 are respectively connected to the end faces of the round block 25 and the circular cavity 701; the end of the top shaft 10 located in the circular cavity 701 is provided with a closing block 28, and the end face of the closing block 28 is provided with a cross platform 2801 for inserting into the cross groove 2501.

[0034] Specifically, after the roller 15 rolls from the upper plane of the bracket 2 to the inclined surface of the inclined block 16, the screw rod 7 continues to move toward the apple 13, and the closing block 28 continues to move toward the round block 25. The cross table 2801 is inserted into the cross slot 2501, and the square shaft 26 slides in the square cavity 702. Then the screw rod 7 is disengaged from the vertical plate 8, and the light rod 6 enters the threaded hole of the vertical plate 8. The spring 19 is compressed, and the screw rod 7 no longer moves toward the apple 13. The motor 15 still drives the light rod 6 and the screw rod 7 to rotate, and the screw rod 7 drives the square shaft 26, the round block 25, the closing block 28 and the top shaft 10 to rotate synchronously. Therefore, the rubber ring 12 and the rubber cylinder 18 clamp the apple 13 to rotate, so the detection device 24 fully identifies the quality of the rubber cylinder 18.

[0035] The box body 23 is provided with a slide 29 that slides horizontally in the direction of the bracket 2, and two guide rods 30 are fixed on the slide 29. The guide rods 30 are slidably arranged on the guide plate 31, and the guide plate 31 is fixedly arranged vertically on the box body 23. The end of the guide rod 30 is provided with a round table that touches the guide plate 31. The outer sleeve of the guide rod 30 is provided with a spring 32, and the two ends of the spring 32 are respectively connected to the slide 29 and the guide plate 31; the slide 29 is provided with a sliding shaft 33, and the middle part of the sliding shaft 33 is provided with a blocking cylinder 34. The two ends of the sliding shaft 33 slide symmetrically. Two slides 35 are provided. A slide rod 36 is slidably provided on the end of the slide rod 35 close to the bracket 2. A plywood 37 for clamping the apple 13 is provided on the slide rod 36. A spring 5 38 is provided on the outer sleeve of the slide rod 36. The two ends of the spring 5 38 are respectively connected to the plywood 37 and the slide rod 35. A connecting plate 39 is hinged on the end of the slide rod 35 away from the bracket 2. The two connecting plates 39 are hinged to a middle plate 40. The middle position of the middle plate 40 is connected to the end of the telescopic shaft of the electric cylinder 41, and the electric cylinder 41 is fixed to the box body 23.

[0036] Specifically, in the original state, the electric cylinder 41 is in an extended state, the cone of the guide rod 30 is in contact with the guide plate 31, the spring four 32 always provides elastic force, and the two slides 35 are in an open state, and the two plywood plates 37 are located on both sides of the apple 13. When the detection device 24 determines that the quality of the apple 13 is unqualified, the electric cylinder 41 is started to shrink the telescopic shaft of the electric cylinder 41. Since the spring four 32 provides elastic force, the slide 29 does not move first, but transmits power through the connecting plate 39, so that the two slides 35 slide toward the middle along the sliding shaft 33. The slide 35 moves toward the direction of the apple 13 with the sliding rod 36 and the plywood 37. After the two plywood 37 clamp the apple 13, the slide 35 continues to slide on the sliding shaft 33, and the sliding rod 36 slides on the slide 35, and the spring five 38 is compressed; when the slide 35 contacts the side of the retaining cylinder 34, the operation of the electric cylinder 41 is stopped, and the motor 5 is started in the reverse direction. The spring 9 provides elastic force, so that the screw rod 7 re-enters the threaded hole of the vertical plate 8, and the above principle is reversed to cause the rubber cylinder 18 and the rubber ring 12 to descend. The electric cylinder 41 is started again, causing the telescopic shaft of the electric cylinder 41 to continue to contract. Since the slide 35 no longer slides on the slide shaft 33, the slide 29 moves synchronously, and the two plywood plates 37 clamp the unqualified apples 13 and move toward the opening of the temporary cavity 2301.

[0037] An end circular plate 42 is provided on the sliding rod 36 at one end away from the plywood 37, and a wedge 43 is provided on the box body 23 for driving the end circular plate 42 to move. A temporary storage chamber 2301 for storing unqualified apples 13 is provided inside the box body 23.

[0038] Specifically, when the apple 13 moves to above the opening of the temporary cavity 2301, the end circular plate 42 contacts the inclined surface of the wedge block 43, and the wedge block 43 drives the end circular plate 42 and the slide rod 36 to move outward, so that the apple 13 of unqualified quality falls into the temporary cavity 2301.

[0039] Taking into account that during the descent of the rubber cylinder 18 and the rubber ring 12, in order to prevent the rubber ring 12 from further damaging the apple 13, a conical shell 44 is further provided at the end of the top shaft 10. The outer surface of the conical shell 44 is a conical surface, and the slide plate 35 is provided with an L-insert plate 45 for driving the conical shell 44 to move.

[0040] Specifically, after the two rubber plates 37 clamp the apple 13, the slide plate 35 continues to slide on the sliding shaft 33, and the L-insert plate 45 contacts the conical surface of the conical shell 44, so that the conical shell 44 and the top shaft 10 move synchronously toward the inside of the screw rod 7, and the rubber ring 12 is separated from the apple 13. Therefore, the rubber ring 12 does not contact the apple 13 during the descent process, thereby preventing the rubber ring 12 from scratching the surface of the apple 13.

[0041] Working principle: Place the apple 13 to be inspected on the inspection plate 22, start motor 21, drive the conveyor belt of the transfer mechanism 20 to operate, the transfer mechanism 20 drives the inspection plate 22 to move, and the inspection plate 22 sends the apple 13 to be inspected between the rubber ring 12 and the rubber cylinder 18. At this time, the apple 13 is located below the detection device 24, and motor 21 stops.

[0042] Apple 13 is initially inspected using detection device 24. Motor 15 is then started, driving polished rod 6 and screw rod 7. The interaction between screw rod 7 and vertical plate 8 causes motor 15 and slide 4 to move toward apple 13. Simultaneously, top shaft 10 and rubber ring 12 also move toward apple 13. After rubber ring 12 contacts apple 13, it pushes apple 13 toward rubber cylinder 18. Thus, rubber ring 12 and rubber cylinder 18 together clamp apple 13. During this process, roller 15 rolls on the upper surface of bracket 2. Motor 15 continues to operate, causing top shaft 10 to slide within screw rod 7, compressing spring 2 11. Roller 15 then rolls from the upper surface of bracket 2 onto the inclined surface of ramp 16, forcing flat plate 3 to slide upward. As a result, rubber ring 12 and rubber cylinder 18 clamp and lift apple 13, separating apple 13 from detection tray 22. This prevents detection tray 22 from obstructing apple 13, allowing the contact position between apple 13 and detection tray 22 to be detected. During this process, the closing block 28 continues to move toward the round block 25, the cross table 2801 is inserted into the cross slot 2501, the square shaft 26 slides in the square cavity 702, and then the screw rod 7 is disengaged from the vertical plate 8, the light rod 6 enters the threaded hole of the vertical plate 8, the spring 19 is compressed, and the screw rod 7 no longer moves toward the direction of the apple 13. The motor 15 still drives the light rod 6 and the screw rod 7 to rotate, and the screw rod 7 drives the square shaft 26, the round block 25, the closing block 28 and the top shaft 10 to rotate synchronously, so the rubber ring 12 and the rubber cylinder 18 clamp the apple 13 to rotate, so the detection device 24 fully identifies the quality of the rubber cylinder 18.

[0043] When the inspection device 24 determines that the quality of the apple 13 is unqualified, the electric cylinder 41 is started to shrink the telescopic shaft of the electric cylinder 41. Since the spring 432 provides elastic force, the slide 29 does not move first, but transmits power through the connecting plate 39, causing the two slides 35 to slide toward the middle along the slide shaft 33. The slide 35 moves toward the apple 13 with the slide rod 36 and the plywood 37. After the two plywood 37 clamp the apple 13, the slide 35 continues to slide on the slide shaft 33, and the slide rod 36 moves on the slide. 35 slides upward, spring 5 38 compresses, and then L-shaped insert 45 contacts the conical surface of conical shell 44, driving conical shell 44 and top shaft 10 to move synchronously toward the interior of screw rod 7, separating rubber ring 12 from apple 13. When slide plate 35 contacts the side of retaining cylinder 34, electric cylinder 41 is stopped, and motor 15 is started in reverse, reversing the above principle to lower rubber cylinder 18 and rubber ring 12. During the descent, rubber ring 12 does not contact apple 13, preventing it from scratching the surface of apple 13. Electric cylinder 41 is started again, causing its telescopic shaft to continue to retract. Since slide plate 35 no longer slides on slide shaft 33, carriage 29 moves synchronously, and the two rubber plates 37, holding the unqualified apple 13, move toward the opening of temporary cavity 2301. When the apple 13 moves to above the opening of the temporary cavity 2301, the end circular plate 42 contacts the inclined surface of the wedge block 43, and the wedge block 43 drives the end circular plate 42 and the slide bar 36 to move outward, so that the apple 13 of unqualified quality falls into the temporary cavity 2301.

[0044] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications based on the present invention to solve substantially the same technical problems and achieve substantially the same technical effects are all included in the scope of protection of the present invention.
