Description

Technical Field

[0001] This application relates to the technical field of defective product sorting machines, and in particular to a defective product sorting machine. Background Technology

[0002] In industrial production, especially in automated production lines, product sorting is a crucial step in ensuring product quality. Currently, defective products are typically sorted manually; some systems utilize automated sorting equipment, such as photoelectric sensors combined with robotic arms or push rods, where detection signals trigger actuators to push defective products off the production line. However, such equipment has drawbacks. For example, its reliance on high-precision sensors and complex control systems leads to high costs and complex maintenance; the robotic arms or push rods require significant actuation space, making them difficult to adapt to compact production line layouts; and the sorting process is delayed, which can cause untimely sorting or accidental triggering during high-speed production, resulting in a mix of qualified and defective products.

[0003] In addition, some traditional sorting machines use a fixed sorting channel structure, which uses inclined slides and baffles to achieve sorting. However, such devices often require solenoid valves or cylinders to control the baffle movement through frequent opening and closing. This not only consumes a lot of energy, but also makes the mechanical parts prone to wear under long-term high-frequency operation, leading to poor sealing or failure of operation. This can cause problems such as qualified products falling out accidentally or defective products remaining, which seriously affects the sorting accuracy and the stability of the production line. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this application is to provide a defective product sorting machine, which can effectively solve the problems of high cost, slow response, frequent maintenance and insufficient sorting reliability of traditional equipment.

[0005] The above-mentioned objective of this application is achieved through the following technical solution:

[0006] A defective product sorting machine includes a support, a loading device, an eccentric wheel device, and a connecting device. The support has a slide rail, which is inclined. The loading device is slidably mounted on the slide rail. The eccentric wheel device is fixedly mounted and has a connecting column offset from the axis of the eccentric wheel device. The connecting device connects the connecting column and the loading device. One side of the support forms a defective product drop space. The loading device moves along the slide rail to operably block the defective product drop space.

[0007] This application is further configured to include a visual recognition device, which is disposed above the cargo-carrying device and connected to the eccentric wheel device.

[0008] The present application further provides that a groove is provided on one end of the connecting device, and the connecting post is disposed in the groove.

[0009] This application further specifies that the chute extends in a direction perpendicular to the slide rail.

[0010] This application further provides that the bottom of the cargo-carrying device is provided with a slider, and the slider is slidably connected to the slide rail.

[0011] This application further specifies that the number of slides is multiple, with every two slides forming a slide assembly, and several slide assemblies arranged side by side.

[0012] This application is further configured such that the bracket bends to form a horizontal part, an inclined part, and a vertical part, the inclined part connects the horizontal part and the vertical part, the vertical part is located below the horizontal part, the slide is arranged on the inclined part, and the space below the vertical part is formed for the defective product to fall.

[0013] This application further specifies that the eccentric wheel device includes a motor and an eccentric wheel assembly, the motor is connected to the shaft of the eccentric wheel assembly, the connecting column is disposed on the eccentric wheel assembly, and the motor is signal-connected to the visual recognition device.

[0014] This application is further configured such that both the motor and the eccentric wheel device are mounted on the horizontal part.

[0015] In summary, the beneficial technical effects of this application are as follows:

[0016] 1. The material sorting machine of this application utilizes a combination of a loading device and an eccentric wheel device to achieve the conveying of qualified products and the return of unqualified products, eliminating the need for manual removal and significantly improving sorting efficiency.

[0017] 2. This application does not rely on high-precision sensors and complex control systems, thus reducing equipment costs compared to existing automated sorting equipment that uses photoelectric sensors in conjunction with robotic arms or push rod structures. Furthermore, the relatively simple structure of this sorting machine reduces maintenance difficulties caused by complex systems, thereby lowering maintenance costs and complexity.

[0018] 3. The cargo-carrying device of this application moves along an inclined slide, with a compact overall structure. Compared with the mechanical arm or push rod, which requires a larger driving space, it can be well adapted to the layout of a compact production line and improve the space utilization efficiency of the production line.

[0022] The present application will be further described in detail below with reference to the accompanying drawings.

[0023] like Figures 1-2 As shown, a defective product sorting machine includes a support 1, a loading device 3, an eccentric wheel device 5, a connecting device 6, and a vision recognition device. The support 1 is provided with a slide rail 2, which is inclined. The loading device 3 is slidably mounted on the slide rail 2. The eccentric wheel device 5 is fixedly mounted and has a connecting column 51 that is offset from the axis of the eccentric wheel device 5. The connecting device 6 connects the connecting column 51 and the loading device 3. A defective product drop space is formed on one side of the support 1. The loading device 3 can be moved along the slide rail 2 to operably block the defective product drop space. The vision recognition device is located above the loading device 3 and is connected to the eccentric wheel device 5.

[0024] Specifically, bracket 1 is made of high-strength aluminum alloy to ensure structural stability when bearing the weight of the equipment itself and the impact forces during material transportation. The overall frame of bracket 1 is designed with an adjustable height, and four rotatable and locking casters are installed at the bottom for easy movement and positioning within the production workshop. It also has height adjustment bolts for precise adjustment according to the height requirements of different production lines.

[0025] The loading device 3 is made of smooth stainless steel plate and has a loading surface with several evenly distributed anti-slip grooves to prevent the product from sliding or deviating along a direction perpendicular to the product's movement during transportation. The two side edges of the loading device 3 are bent upward to form baffles, effectively preventing the product from falling off the sides during transportation. Two sets of high-precision linear slide rail sliders 4 are installed at the bottom of the loading device 3, which fit tightly with the guide rails on the slide rail 2 to ensure that the loading device 3 can slide smoothly and steadily on the slide rail 2.

[0026] The eccentric wheel device 5 is driven by a DC servo motor with high-precision speed control, which can precisely adjust the rotation speed of the eccentric wheel according to the conveying speed of the products on the production line. The eccentric wheel is forged from high-quality alloy steel and undergoes precision machining and heat treatment processes to ensure its strength and wear resistance. The connecting column 51 is fixedly connected to the eccentric wheel by a high-strength pin, and the end of the connecting column 51 is designed with threads for connection with the connecting device 6.

[0027] The connecting device 6 is a connecting rod made of high-strength aluminum alloy, characterized by its light weight and high strength. A groove 61 is formed at one end of the connecting device 6, and the connecting post 51 is disposed within the groove 61, which extends perpendicular to the slide rail 2. Preferably, the width of the groove 61 is designed to be 0.5mm larger than the diameter of the connecting post 51, ensuring that the connecting post 51 can slide smoothly within the groove 61 without excessive wobbling. The length of the groove 61 is determined based on the maximum displacement of the connecting post 51 when the eccentric wheel rotates, ensuring that the connecting post 51 remains within the groove 61 throughout the full stroke of the eccentric wheel. The surface of the groove 61 undergoes high-precision grinding and polishing, preferably with a roughness of Ra0.8μm, to reduce friction between the connecting post 51 and the groove 61, thereby improving the transmission efficiency and service life of the device.

[0028] When the eccentric wheel device 5 receives a control signal from the visual recognition device and begins to rotate, the connecting column 51 moves in a circular motion along with the eccentric wheel. Since the connecting column 51 is located within the groove 61 at one end of the connecting device 6, and the groove 61 extends perpendicular to the slide rail 2, the connecting column 51 slides within the groove 61, causing the connecting device 6 to swing. This swinging motion is transmitted to the loading device 3 through the connection between the other end of the connecting device 6 and the loading device 3, causing the loading device 3 to produce a displacement on the slide rail 2 that conforms to a predetermined trajectory. For example, when the eccentric wheel starts to rotate clockwise from its initial position, the connecting column 51 slides away from the slide rail 2 within the groove 61, and the connecting device 6 swings accordingly, pushing the loading device 3 away from the defective product drop space; when the eccentric wheel continues to rotate, and the connecting column 51 slides in the opposite direction within the groove 61, the loading device 3 moves closer to the defective product drop space, thereby achieving control over the opening and blocking of the defective product drop space. See also Figure 1 In this process, products without problems are transported along the first transport direction L1, while defective products are transported along the second transport direction L2.

[0029] A groove 61 is provided at one end of the connecting device 6, and the connecting column 51 is placed within it. This allows the connecting device 6 to better adapt to changes in angle and displacement when transmitting the motion of the eccentric wheel. Compared to traditional rigid connection methods, this design allows the connecting column 51 to slide freely within the groove 61, effectively compensating for the complex motion generated during the rotation of the eccentric wheel, enhancing the flexibility and smoothness of the entire device's movement, avoiding equipment failures caused by motion interference, and further improving the stability of equipment operation.

[0030] The design feature of the chute 61 extending perpendicular to the slide rail 2 allows the connecting device 6 to precisely convert the circular motion of the eccentric wheel into linear displacement of the loading device 3 along the slide rail 2. By precisely designing the length and position of the chute 61 and the parameters of the eccentric wheel, precise control of the displacement of the loading device 3 can be achieved, ensuring that during defective product sorting, the loading device 3 can accurately move to the predetermined position to open or block the space for defective products to fall, thereby improving the accuracy and reliability of sorting.

[0031] Furthermore, the visual recognition device uses an industrial-grade high-definition camera, paired with a high-performance image recognition processor. The camera's installation angle and position can be precisely adjusted via the adjustable bracket 1 to ensure clear and comprehensive imaging of the products on the cargo carrier 3. The image recognition processor incorporates advanced image recognition algorithms, enabling rapid and accurate identification of product defects with a high accuracy rate. The visual recognition device is connected to the eccentric wheel device 5 via a data cable, enabling real-time data transmission and control signal interaction.

[0032] The eccentric wheel device 5 is in its initial position, and the loading device 3 is located at the top of the slide 2, completely blocking the space for defective products to fall. The production line transports the products onto the loading device 3, and the products slide down naturally on the loading device 3 based on the tilt angle of the slide 2.

[0033] The visual recognition device captures and analyzes images of the product in real time. The device then transmits the acquired image data to an image recognition processor, which uses built-in algorithms to process and analyze the images to determine whether the product is defective.

[0034] If the visual recognition device determines the product is qualified, it does not send a control signal to the eccentric wheel device 5. The eccentric wheel device 5 remains in its current state, and the loading device 3 continues to slide down the slide 2, transporting the qualified product to the next process. If the visual recognition device determines the product is defective, it immediately sends a control signal to the eccentric wheel device 5. Upon receiving the control signal, the motor of the eccentric wheel device 5 starts to drive the eccentric wheel to rotate, causing the loading device 3 to move on the slide 2 via the connecting device 6. When the eccentric wheel rotates to a specific angle, the loading device 3 moves to a certain position, no longer obstructing the space for defective products to fall. Under the action of its own gravity, the defective product falls from the loading device 3 to the defective product collection area.

[0035] After the defective products are sorted, the eccentric wheel device 5 continues to rotate, bringing the loading device 3 back to its initial position, covering the space where the defective products fall again, and waiting for the next product to arrive before starting the next round of sorting.

[0036] This completely eliminates manual sorting, avoiding missed inspections or misjudgments caused by human fatigue, and greatly improves the accuracy and efficiency of sorting. Through visual recognition devices and automated mechanical structures, uninterrupted, high-precision product sorting is achieved, significantly improving production efficiency and product quality.

[0037] Compared to existing automated sorting equipment, this system eliminates the need for high-precision sensors and complex control systems, reducing equipment costs. Furthermore, the adoption of a relatively simple and reliable mechanical structure and mature visual recognition technology significantly reduces maintenance difficulty and costs. Routine maintenance only requires periodically checking the wear and tear of each mechanical component, cleaning the lens of the visual recognition device, and performing simple calibrations.

[0038] The overall structure is compact, with the cargo carrier 3 moving along the inclined slide 2, requiring minimal driving space. It can be easily adapted to both newly built compact production lines and upgrades of existing ones, effectively improving the space utilization of the production line and saving valuable production space for enterprises.

[0039] Furthermore, the bottom of the cargo carrier 3 is equipped with a slider 4, which is slidably connected to the slide rail 2. The slider 4 is made of wear-resistant, high-strength engineering plastic material, such as a composite material of polytetrafluoroethylene (PTFE) and carbon fiber. This material not only has excellent wear resistance, effectively reducing frictional loss between the slider and the slide rail 2 and extending the service life of the equipment, but also has good self-lubricating properties, reducing the need for additional lubrication maintenance. The slider 4 is designed in the shape of a cuboid, and its bottom surface in contact with the slide rail 2 is machined with a high-precision plane, with a flatness error controlled within ±0.05mm, to ensure a tight and uniform fit with the slide rail 2. On both sides of the slider 4, a set of stainless steel balls with a diameter of 5mm are embedded. Through a precise installation process, the balls can roll freely within the slider 4, further reducing the coefficient of sliding friction. Four such sliders 4 are evenly installed on the bottom of each cargo carrier 3, distributed at the four corners of the bottom of the cargo carrier 3, to ensure the stability and balance of the cargo carrier 3 when sliding on the slide rail 2.

[0040] When the eccentric wheel device 5 drives the loading device 3 to move via the connecting device 6, the slider 4 at the bottom of the loading device 3 slides on the slide rail 2. Due to the tight fit between the high-precision plane of the slider 4 and the slide rail 2, and the rolling action of the balls, the loading device 3 can move smoothly along the slide rail 2. During the defective product sorting process, when the eccentric wheel rotates and moves the loading device 3 in the direction of opening the defective product drop space, the slider 4 slides smoothly on the slide rail 2, ensuring that the loading device 3 accurately reaches the predetermined position and allows the defective products to fall smoothly; when the sorting is completed and the eccentric wheel drives the loading device 3 to reset, the slider 4 also slides stably in the opposite direction, bringing the loading device 3 back to the initial position, ready to receive the next sorting task. Throughout the process, the excellent sliding performance of the slider 4 ensures the accuracy and efficiency of the movement of the loading device 3.

[0041] The bottom of the loading device 3 is equipped with a slider 4 that is slidably connected to the slide rail 2, which greatly improves the stability of the loading device 3's movement on the slide rail 2. Compared with the direct contact sliding method without slider 4, the slider 4, through its high-precision flat surface and the rolling of the balls, effectively reduces problems such as shaking and jamming of the loading device 3 caused by unevenness of the slide rail 2 surface or uneven friction, making the movement of the loading device 3 more stable and smooth. This ensures the stability of the products during the sorting process and avoids product damage or sorting errors caused by the unstable movement of the loading device 3.

[0042] The wear-resistant materials and self-lubricating design used in slider 4 significantly reduce frictional losses between the loading device 3 and the slide rail 2. This not only extends the service life of both slide rail 2 and loading device 3, reducing the frequency of equipment maintenance and parts replacement, and lowering the company's operating costs, but also ensures that the equipment maintains good working performance during long-term operation, guaranteeing the continuous and stable operation of the production line. At the same time, the lower coefficient of friction means that less power is required to drive the loading device 3, further reducing the equipment's energy consumption.

[0043] Furthermore, there are multiple slides 2, with each pair of slides 2 forming a slide 2 assembly, and several slide 2 assemblies arranged side by side.

[0044] Preferably, each slide rail 2 is made of aluminum alloy and the surface is anodized to enhance its wear resistance and corrosion resistance. The cross-section of the slide rail 2 is designed in a U-shape with a depth of 8cm to ensure that the product slides stably on the slide rail 2. Every two slide rails 2 form a slide rail 2 assembly.

[0045] Furthermore, the bracket 1 is bent to form a horizontal part 11, an inclined part 12 and a vertical part 13. The inclined part 12 connects the horizontal part 11 and the vertical part 13. The vertical part 13 is located below the horizontal part 11. The motor is mounted on the horizontal part 11. The slide 2 is located on the inclined part 12. A space for defective products to fall is formed below the vertical part 13.

[0046] Preferably, the bracket 1 is integrally bent from high-quality Q345 steel to ensure the stability and integrity of the structure. The horizontal part 11 is 1.5cm thick, and its surface is treated for flatness, with the flatness error controlled within ±0.05mm, providing a stable foundation for motor installation. Preferably, the angle between the inclined part 12 and the horizontal part 11 is designed to be 45°, which ensures that the product slides smoothly down the slide rail 2 under its own weight, while also taking into account the overall spatial layout and stability of the equipment. The area on the inclined part 12 where the slide rail 2 is installed has pre-machined mounting holes that fit the slide rail 2, with the hole position accuracy controlled within ±0.1mm to ensure that the slide rail 2 is installed firmly. The height of the vertical part 13 is customized according to actual production needs and the height of the defective product collection container, and the bottom is designed with reinforcing ribs to enhance its load-bearing capacity.

[0047] The selected motor is an AC asynchronous motor with precise speed control. The power is determined according to the overall operating requirements of the material sorting machine, generally ranging from 1KW to 3KW. The motor is fixed to the horizontal part 11 by high-strength shock-absorbing rubber pads and bolts. The shock-absorbing rubber pads are 2cm thick, which can effectively reduce the vibration generated by the motor during operation and transmit it to the support 1, thereby reducing the operating noise of the equipment.

[0048] A movable defective product collection box is installed within the defective product drop area. The collection box is made of stainless steel and has a volume of 0.5 m³.3 ~1m 3 It has a large opening for easy collection of defective products. Four braked casters are installed at the bottom of the collection box for easy movement and replacement.

[0049] The bend design of the bracket 1 rationally divides the motor, slide 2, and defective product drop space into separate zones. The motor is placed in the horizontal section 11, making full use of the space above the equipment and avoiding the motor occupying too much ground space; the slide 2 is set in the inclined section 12, which conforms to the principle of product gravity sliding down, saving additional conveying power; the defective product drop space is formed below the vertical section 13, which separates the defective product collection area from other parts, improves space utilization efficiency, and makes the structure of the entire sorting machine more compact and reasonable.

[0050] The support frame 1 is made of high-quality steel formed by one-piece bending, and the mutual support structure of the horizontal part 11, the inclined part 12, and the vertical part 13 greatly enhances the overall stability of the equipment. The motor is installed in the horizontal part 11 and connected to the support frame 1 through a shock-absorbing rubber pad, which reduces the impact of motor vibration on other parts of the equipment and ensures that the material distributor maintains a stable working state during high-speed operation and long-term work, reducing the probability of equipment failure.

[0051] Furthermore, the eccentric wheel device 5 includes a motor and an eccentric wheel assembly. The motor is axially connected to the eccentric wheel assembly, and a connecting column 51 is provided on the eccentric wheel assembly. The motor is signal-connected to the visual recognition device. Both the motor and the eccentric wheel device 5 are mounted on the horizontal part 11.

[0052] Preferably, the motor is an AC servo motor with high torque output and precise speed control characteristics. Its rated power is typically set between 1KW and 4KW, depending on the overall load and operating requirements of the material distributor. The motor's speed adjustment range is 0-3000 rpm, and it can be precisely controlled via a matching driver, with a speed control accuracy of ±1 rpm. The motor shaft diameter is 30mm, made of alloy steel, and undergoes high-precision grinding and heat treatment processes to ensure its strength and wear resistance, meeting the requirements for stable long-term drive of the eccentric wheel assembly.

[0053] Preferably, the eccentric wheel body is made of high-strength ductile iron, precision cast and machined. The eccentric wheel has a diameter of 200mm and a thickness of 50mm. The eccentricity, i.e., the distance between the center of the connecting column 51 and the axis of the eccentric wheel, is designed to be 30mm. This parameter has been optimized to ensure the effective displacement of the loading device 3 while ensuring the smooth rotation of the eccentric wheel. Furthermore, the connecting column 51 is made of 45# steel with a diameter of 20mm. It is connected to the eccentric wheel assembly by an interference fit, with the interference controlled between 0.03mm and 0.05mm. It is further reinforced with a high-strength key connection to ensure that the connecting column 51 will not loosen or shift during the rotation of the eccentric wheel.

[0054] The motor and the vision recognition device are connected via a high-speed industrial Ethernet signal. The vision recognition device is equipped with a built-in control system. The vision recognition device has an Ethernet communication interface, and the motor driver also supports the Ethernet communication protocol. In this way, the vision recognition device's control system can quickly transmit signals to the motor driver the moment a defective product is detected, achieving precise control of the motor. Simultaneously, the motor's operating status, such as speed and direction, can be fed back to the vision recognition device's control system in real time for system monitoring and fault diagnosis.

[0055] After the production line starts, products are conveyed to the horizontal section 11 and then enter the slide 2 of the inclined section 12. The vision recognition device acquires and analyzes images of the products on the slide 2 in real time. When the vision recognition device detects a defective product, it immediately sends a control signal to the motor through the control system. Upon receiving the signal, the motor driver quickly adjusts the motor's speed and direction, driving the eccentric wheel assembly to rotate. As the eccentric wheel rotates, the connecting column 51 performs a circular motion, driving the loading device 3 to move on the slide 2 via the connecting device 6, opening the defective product drop space, allowing the defective products to fall into the collection box. Throughout the process, the motor adjusts its operating status in real time according to the signals from the vision recognition device, ensuring that the rotation of the eccentric wheel assembly accurately matches the product detection results. For example, when multiple consecutive defective products are detected, the motor can respond quickly, controlling the eccentric wheel assembly to rotate at an appropriate speed and frequency, achieving fast and accurate sorting.

[0056] The signal connection between the motor and the vision recognition device enables precise control and rapid response of the eccentric wheel assembly 5. Once the vision recognition device detects a defective product, it immediately transmits a signal to the motor, which reacts quickly, driving the eccentric wheel assembly to move. This significantly shortens the time interval between detection and sorting, improving the timeliness and accuracy of sorting. Compared to traditional control methods, this direct signal connection avoids signal transmission delays and interference, ensuring the stable operation of the sorting machine in high-speed production environments.

[0057] By precisely controlling the motor's speed and direction, the rotation angle and speed of the eccentric wheel assembly can be accurately adjusted, thereby enabling more precise control of the displacement and movement time of the loading device 3. This significantly improves the sorting accuracy of defective products and effectively reduces missorting. Simultaneously, the rapid response speed allows the sorting machine to process more products per unit time, further improving sorting efficiency and meeting the demands of large-scale, high-precision production.

[0058] The communication connection between the motor and the vision recognition device not only enables control functions but also facilitates monitoring and fault diagnosis of the entire material distribution system. By monitoring the motor's operating status and the detection data from the vision recognition device, operators can understand the material distributor's operation in real time and promptly identify potential faults. In the event of a fault, the system can quickly locate the problem, facilitating repair and maintenance by maintenance personnel, reducing equipment downtime, and improving production continuity and stability.

Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
