Description

Technical Field

[0001] This utility model relates to the field of apple fruit color detection technology, and in particular to an apple fruit color monitoring device with nighttime supplementary lighting function. Background Technology

[0002] The surface color of apples is one of the key indicators for evaluating their appearance quality and product grade. In the post-harvest processing of apples, traditional manual sorting methods are not only inefficient and labor-intensive, but also prone to inconsistent judgment standards due to subjective factors, affecting the accuracy of grading.

[0003] Currently, automated sorting equipment using machine vision technology is available on the market, capturing images of apples through cameras and performing color analysis. However, these devices still have some limitations in practical applications. First, a single inspection process may result in misjudgments or missed detections due to factors such as apple posture, surface reflection, or brief equipment interference. The lack of an effective verification mechanism means the reliability of rejecting defective products needs improvement. Second, these devices have strict requirements for lighting conditions, especially when operating at night or in orchards with poor lighting. Insufficient ambient light significantly affects image acquisition quality, causing the color detector to fail to accurately identify the true color of the fruit, thus reducing the reliability and stability of the entire monitoring system.

[0004] Therefore, there is an urgent need for a solution in the existing technology for monitoring the color of apple fruits that can improve detection accuracy, ensure normal operation in low light conditions, and effectively reduce the rate of missed defects. Summary of the Invention

[0005] In order to overcome the shortcomings of existing apple color monitoring equipment, such as easy to miss detection in a single test and decreased reliability in low light environment, this utility model provides an apple fruit color monitoring device with nighttime supplementary lighting function.

[0006] The technical implementation scheme of this utility model is as follows: an apple fruit color monitoring device with nighttime supplementary lighting function, including a U-shaped belt drive, an outer frame, an alarm, a protective curtain, a mounting plate, a color detector, a top supplementary light, and a control component. The U-shaped belt drive uses a U-shaped conveyor belt as the core conveying component for apples. The left end of the U-shaped belt drive is set as the inlet end, and the right end is set as the outlet end. Outer frames are installed on both sides of the U-shaped belt drive. The inlet and outlet ports of each outer frame are connected to a protective curtain. A mounting plate is installed at the top inside the outer frame. A color detector is installed at the bottom center of the mounting plate. Top supplementary lights are installed on both sides of the color detector on the mounting plate. An alarm is installed at the top of each outer frame. The alarm is connected to the color detector inside the corresponding outer frame through a wire. The inlet end of the U-shaped belt drive is equipped with a control component.

[0007] As an improvement to the above solution, the quantity control component includes a feeding frame, a controller, a quantity control slant block, an adjusting screw, and a material feeding component. The feeding frame is installed at the top of the feeding end of the U-shaped belt drive. The controller is fixedly connected to the front side wall of the feeding frame. The alarm, color detector, and top position supplementary light are all electrically connected to the controller. The feeding frame has symmetrically opened grooves. The quantity control slant block is slidably connected between the two grooves. The quantity control slant block has a guide slope on its front side. The adjusting screw is rotatably connected to the left side of the feeding frame. The adjusting screw is threadedly connected to the left end of the quantity control slant block. The quantity control slant block is equipped with a material feeding component.

[0008] As an improvement to the above solution, the feeding assembly includes a lifting screw and a baffle. A guide groove is opened inside the control block, and a baffle is slidably connected to the guide groove. The lifting screw is threadedly connected to the top center of the control block, and the bottom end of the lifting screw passes through the guide groove and is rotatably connected to the top center of the baffle.

[0009] As an improvement to the above solution, side light strips are also included. Side light strips are installed on both sides of the inner side wall of the outer frame, and the side light strips are electrically connected to the controller.

[0010] As an improvement to the above solution, a discharge hopper is also included, with the discharge end of the U-shaped belt drive connected to the position corresponding to the conveyor belt.

[0011] As an improvement to the above solution, handwheels are fixedly connected to the operating ends of both the adjusting screw and the lifting screw.

[0012] The beneficial effects of this utility model are: 1. This device achieves continuous two-level color monitoring of apples through the cooperation of the U-shaped belt drive and the two outer frames on the left and right. When the color detector in either outer frame detects a defective product, it will immediately trigger the alarm through the controller to issue an audible and visual alarm. This allows the staff to respond quickly and pick out the defective products from the conveyor line, effectively reducing the missed detection rate and ensuring the consistency of the quality of the apples leaving the factory.

[0013] 2. The device has a top-mounted supplementary light installed inside the outer frame and side light strips added to the left and right side walls. In the dark or in low-light environments, these supplementary lighting devices can be turned on by the controller to provide sufficient and uniform lighting conditions for the color detector, ensuring the clarity of image acquisition and the accuracy of color judgment, thereby extending the working time and application scenarios of the device.

[0014] 3. The position of the control block can be flexibly adjusted by the adjusting screw in the control component, thereby changing the size of the feeding channel, controlling the amount of apples fed at one time, and avoiding congestion. At the same time, the height of the baffle can be adjusted by the lifting screw in the feeding component to accommodate apples of different sizes, ensuring that the apples are laid flat in a single layer on the conveyor belt, effectively preventing stacking and providing the best observation conditions for color detection.

Detailed Implementation

[0022] Example: An apple fruit color monitoring device with nighttime supplemental lighting function, such as... Figures 1-6As shown, the system includes a U-shaped belt drive 1, a discharge hopper 101, an outer frame 2, an alarm 3, a protective curtain 4, a mounting plate 5, a color detector 6, a top-mounted supplementary light 7, side-mounted light strips 8, and a quantity control component. The U-shaped belt drive 1 uses a U-shaped conveyor belt as the core conveying component for apples. The left end of the U-shaped belt drive 1 is the inlet end, and the right end is the outlet end. The outer frame 2 is bolted to both sides of the U-shaped belt drive 1, forming a two-stage monitoring structure. The front and rear inlet and outlet ports of each outer frame 2 are collinear with the apple conveying path of the U-shaped belt drive 1, ensuring that the apples can smoothly enter and exit the outer frame 2 along the conveying path. Each inlet and outlet port of the outer frame 2 is connected to a protective curtain 4 to reduce external light interference. A mounting plate 5 is bolted to the top of the inner side of the outer frame 2. A color detector 6 is installed in the middle of the bottom of the mounting plate 5. Top-position supplementary lights 7 are installed on the left and right sides of the color detector 6 by screws. Side light strips 8 are installed on the left and right side walls inside the outer frame 2 by screws. They can work together with the top-position supplementary lights 7 to improve the uniformity of illumination inside the outer frame 2 and ensure the clarity of nighttime detection. An alarm 3 is installed on the top of the outer frame 2. The alarm 3 is inserted into the corresponding chamber of the outer frame 2 by wires and is electrically connected to the color detector 6 inside the outer frame 2 to realize the real-time transmission of defective product detection signals. The feed end of the U-shaped belt drive 1 is equipped with a quantity control component. The discharge end of the U-shaped belt drive 1 is connected to the discharge hopper 101 at the position corresponding to the conveyor belt. Apples that pass the secondary monitoring can slide down the discharge hopper 101 for collection, realizing orderly collection.

[0023] like Figure 2 and Figures 4-6 As shown, the quantity control component includes a feeding frame 9, a controller 10, a quantity control inclined block 11, an adjusting screw 12, and a feeding assembly. The feeding frame 9 is bolted to the top of the inlet end of the U-shaped belt drive 1. The controller 10 is bolted to the front side wall of the feeding frame 9. The alarm 3, color detector 6, top supplementary light 7, and side light strip 8 are all electrically connected to the controller 10 to achieve centralized control and signal interaction of the components. The feeding frame 9 has symmetrically opened grooves on the left and right sides, and the two grooves slide together. A control ramp 11 is connected, and a guide ramp is provided on the front side of the control ramp 11. The space formed between the front side of the control ramp 11 and the front wall of the U-shaped belt drive 1 constitutes the apple feeding channel. An adjusting screw 12 is rotatably connected to the left side of the feeding frame 9. The adjusting screw 12 is threadedly connected to the left end of the control ramp 11. By rotating the adjusting screw 12 in the forward or reverse direction, the control ramp 11 can be driven to slide back and forth along the slide, thereby adjusting the width of the feeding channel and realizing the feeding amount control. A feeding component is provided on the control ramp 11.

[0024] like Figures 5-6As shown, the feeding assembly includes a lifting screw 13 and a baffle 14. The control block 11 has a guide groove inside, and the baffle 14 is vertically slidably connected to the guide groove. The lifting screw 13 is threadedly connected to the top center of the control block 11. The bottom end of the lifting screw 13 passes through the guide groove and is rotatably connected to the top center of the baffle 14. The baffle 14 is located above the conveyor belt of the U-shaped belt drive 1 and is used to limit the stacking height of the apples. The operating ends of the adjusting screw 12 and the lifting screw 13 are both fixedly connected to handwheels. By setting the handwheels, the operator can quickly and effortlessly manually adjust the front and rear positions of the control block 11 and the height of the baffle 14 without the aid of tools.

[0025] The harvested apples to be monitored are fed into the feed end of the U-shaped belt drive 1. After being guided by the guide slope of the control block 11, the apples fall onto the conveyor belt. According to the batch characteristics and size of the apples to be monitored, the control component is adjusted by rotating the adjusting screw 12 in the forward or reverse direction, driving the control block 11 to slide back and forth along the chute, adjusting the width of the feeding channel to control the feeding amount. At the same time, the lifting screw 13 is rotated in the forward or reverse direction, driving the lifting screw 13 to move axially, causing the baffle 14 to slide vertically up and down along the guide groove, adjusting the distance between the baffle 14 and the conveyor belt to adapt to the size of the apples and ensure that the apples can be laid flat on the surface of the conveyor belt to avoid stacking. Then, the U-shaped belt drive 1 is started by operating the controller 10, driving the conveyor belt to run along the U-shaped route, and the color detector 6, the top supplement light 7 and the side light strip 8 (at night or in the case of insufficient light) are started simultaneously to ensure that the lighting inside the outer frame 2 meets the detection requirements.

[0026] Apples are conveyed to the left outer frame 2 by a conveyor belt. The protective curtain 4 at the inlet / outlet is pushed aside, allowing the apples to enter the inner cavity of the outer frame 2. The color detector 6 inside the left outer frame 2 performs an initial color check on the apples. After this initial check, the apples are output by the conveyor belt and continue to the right outer frame 2. The protective curtain 4 is pushed aside again, and the apples enter the inner cavity. The color detector 6 inside the right outer frame 2 then performs a second check, achieving double screening. If either color detector 6 in the outer frame 2 detects an apple as a substandard product with unacceptable color, it immediately sends a defective product detection signal to the controller 10, triggering the control... After receiving the signal, the device 10 controls the alarm 3 on the top of the outer frame 2 to issue an audible and visual alarm, prompting the staff. Based on the obvious difference in skin color between the defective apples and the qualified apples, the staff can pick out the defective apples on the conveyor belt. The qualified apples after secondary monitoring are transported to the discharge hopper 101 by the conveyor belt and slide down to the collection component to complete the collection of qualified apples. After the apple monitoring operation is completed, the U-shaped belt drive 1, color detector 6, top supplementary light 7 and side light strip 8 are turned off by the operation controller 10 to complete the shutdown operation.
