Description

Technical Field

[0001] This utility model relates to the field of UV processing technology, and more specifically, to a disordered loading and unloading device for UV lines. Background Technology

[0002] A UV line, or UV curing production line, is widely used in the coating and printing industries. For example, a UV coating line can spray and cure workpieces. The process includes electrostatic dust removal, preheating, primer and surface spraying, leveling and drying. Using UV lamps and UV coatings, the coating is instantly cured. It is also used in printing, allowing ink to cure rapidly under UV irradiation. It features high efficiency, environmental friendliness, and high coating quality, meeting the surface treatment needs of industries such as automotive, furniture, and electronics. The core of a UV line relies on UV curing technology. First, automated equipment evenly coats the workpiece surface with UV coating containing photoinitiators. Then, the workpiece enters the UV curing zone, where UV lamps emit specific wavelengths of ultraviolet light to irradiate the coating, activating the photoinitiator and triggering rapid cross-linking and polymerization reactions of the resin and other components within the coating. Curing is completed within seconds, resulting in a hardened coating and a wear-resistant, aesthetically pleasing protective or printed layer on the workpiece surface. Because the material loading and unloading process in a UV line directly affects processing efficiency, it is necessary to perform material clamping and loading operations.

[0003] In related technologies, during the use of UV lines, workers typically manually load and unload the materials to be processed, placing them on the material conveying and processing line for use.

[0004] However, in the current use of UV lines, the process of placing materials requires workers to perform repetitive operations for a long time, which involves a large physical exertion. This makes the material handling and loading / unloading operations of UV lines inconvenient, affecting the convenience and efficiency of the material handling and loading / unloading operations.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Reference Figures 1-3This utility model provides a technical solution: a UV line disordered loading and unloading device, including a roller conveyor 1 and a loading and unloading mechanism. A base frame 2 is installed at the bottom of the roller conveyor 1, and vision sensors 3 are installed on both sides of the top of the roller conveyor 1. While detecting external materials, the device can grab and load the incoming materials, and can also temporarily store the materials during loading and unloading to ensure the stability of the material processing rhythm. This avoids difficulties in loading and unloading during material conveying and processing, which would lead to inconvenience and reduced efficiency in material processing operations. Therefore, it improves the convenience and efficiency of the loading and unloading operation of the roller conveyor 1.

[0027] Reference Figures 1-3 In a preferred embodiment, the loading and unloading mechanism includes a robotic arm base 4, which is disposed on both sides of the roller conveyor 1. A robotic arm 5 is mounted on the top of the robotic arm base 4, and a robotic arm suction device 6 is fixedly connected to the inner side of the robotic arm 5. A temporary storage area 7 is provided on the right side of the top of the roller conveyor 1. When the roller conveyor 1 is working, the robotic arm 5 identifies the position of the material through the vision sensor 3. When the material moves to the position, the robotic arm 5, in conjunction with the robotic arm suction device 6, grabs and places the material on the top of the roller conveyor 1, realizing the loading and unloading operation of the material. At the same time, the material can be temporarily stored to control the material processing rhythm. A controller 8 is fixedly connected to the bottom of the robotic arm base 4. The robotic arm 5 and the vision sensor 3 are both connected to the controller 8. Since the controller 8 is equipped with an EtherCat gateway, nodes such as the joint servo motor of the robotic arm 5, the vision sensor 3, and the actuator of the robotic arm suction device 6 can be connected to the network to realize data interaction. The TwinCAT automation software is used for motion control programming, which supports path dynamic planning algorithm and automatically generates the optimal grabbing trajectory based on the material position information, thus improving the working coordination of the robotic arm 5.

[0028] Reference Figures 2-3In a preferred embodiment, a powered roller hydraulic lifting platform 9 is installed on both sides of the bottom of the roller conveyor 1 at the bottom of the robot base 4. The powered roller hydraulic lifting platform 9 is connected to the controller 8 and can adjust its height according to the actual material feeding requirements. It is equipped with a three-dimensional coordinate positioning module and a high-precision linear displacement sensor 3 to achieve precise control of the lifting height. It is also equipped with an inclination sensor 3 to ensure that the platform's level error is less than 0.5 degrees during the lifting process, preventing material slippage. Side limit baffles are added to enhance material stability. Therefore, the flexibility of the feeding height adjustment is improved. A powered ground roller platform 10 is installed at the bottom of the roller conveyor 1. The powered ground roller platform 10 is located inside the powered roller hydraulic lifting platform 9 and is connected to the controller 8. It can provide a feeding and unloading return conveying rhythm for the material. The powered ground roller platform 10 adopts a variable frequency driven roller design and can adjust the conveying speed according to the weight and type of UV line material to realize the initial conveying and buffer function of the material, thus improving the feeding and unloading return effect of the material.

[0029] Reference Figures 2-3 In a preferred embodiment, side supports 11 are fixedly connected to both sides of the top of the powered roller platform 10. The right side of the inner side of the side supports 11 is inclined, which forms a barrier and stabilizing medium on the top of the powered roller platform 10 to prevent material backflow. The inclined inner side can guide the material, allowing it to move with the inner side of the powered roller platform 10 and preventing it from shifting position and falling during the backflow process. This improves the material conveying stability and guiding performance of the powered roller platform 10. Safety fences 12 are installed on the outer sides of both the roller conveyor 1 and the powered roller platform 10. When the robot arm 5 works with the roller conveyor 1, the powered roller hydraulic lifting platform 9, and the powered roller platform 10, a stabilizing isolation medium is formed on the outer side, ensuring that material loading and unloading are carried out within a safe area. This prevents workers from accidentally entering the loading and unloading processing area and making mistakes, thus improving the safety of the robot arm 5 in the loading and unloading process.

[0030] Specifically, the working process or principle of this UV line disordered loading and unloading device is as follows: During use, the operator randomly places the UV line material to be processed on top of the power roller hydraulic lifting platform 9 at the loading position. The vision sensor 3 built into the power roller hydraulic lifting platform 9 immediately detects the material height. Based on preset parameters or the gripping requirements of the robotic arm 5, the hydraulic system automatically adjusts the platform height to ensure the material is in the optimal gripping position of the robotic arm 5. Simultaneously, the vision system equipped above quickly scans the material's shape, position, and posture, generating point cloud data, and transmitting it via EtherCat. The gateway transmits high-speed data to the controller 8 of the robotic arm 5. Based on the data provided by the vision system, the robotic arm 5 plans the optimal movement path to avoid surrounding equipment. The robotic arm 5 drives the robotic suction device 6 to precisely grab the material on the power roller hydraulic lifting platform 9. Subsequently, the robotic arm 5 transports the material to the top of the roller conveyor 1. At this time, the vision sensor 3 on the top of the roller conveyor 1 continues to scan and identify the material and transmits the information to the controller 8. This prepares the robotic arm 5, located on the right side of the roller conveyor 1, to grab the filtered material conveyed from the top of the roller conveyor 1. At the same time, it identifies and detects the surface of the material. When there are defects on the material surface, it transmits a signal to the controller 8. After the roller conveyor 1 transports normal material to the right side, the robotic arm 5, in conjunction with the robotic suction device 6, grabs the material on the top of the roller conveyor 1, removes the material from the top of the roller conveyor 1, and moves it to the top of the power roller hydraulic lifting platform 9 at the return position. After the material is placed on the top of the power roller hydraulic lifting platform 9, the power roller hydraulic lifting platform 9 moves the material towards the power roller conveyor 1. The ground roller table 10 conveys materials. At this time, the side support 11 provides external obstruction and stabilization for the materials conveyed by the power roller hydraulic lifting platform 9. The inclined surface on the inner side guides the materials, allowing the power roller table 10 to stably convey and return the materials. During this process, the controller 8 controls the power roller table 10 according to the working status of the power roller hydraulic lifting platform 9 and the robot 5. If the robot 5 and the power roller hydraulic lifting platform 9 are operating at high frequency, the controller 8 stops the material conveying and return, and buffers the material. After the roller conveyor 1 conveys the defective materials to the right side, the robot 5, in conjunction with the robot suction device 6, grabs the materials on the top of the roller conveyor 1, removes the materials from the top of the roller conveyor 1, and moves the materials to the temporary storage area 7 for temporary storage of defective products so that the staff can perform unified processing operations on the products later. At the same time, the safety fence 12 encloses the loading and unloading area of ​​the robot 5 to prevent staff from accidentally entering the loading and unloading area of ​​the robot 5.

[0031] It should be noted that the roller conveyor 1, vision sensor 3, robot arm 5, robot arm suction device 6, controller 8, power roller hydraulic lifting platform 9 and power ground roller platform 10 are all existing devices or equipment, or devices or equipment that can be implemented by existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
