Description

Technical Field

[0001] This utility model relates to the technical field of machine material handling devices, specifically a backlight product positioning robot material handling mechanism. Background Technology

[0002] Backlight product positioning robot picking mechanism refers to an automated robot mechanism specifically used in backlight product production lines to accurately position, grasp, and transport backlight products. This mechanism typically combines advanced machine vision technology, precise mechanical design, and a highly efficient control system to achieve efficient, accurate, and reliable automated production.

[0003] For example, the existing material handling robot with publication number CN216032092U specifically discloses: a mounting platform, a gripping manipulator, a linkage mechanism, and a drive assembly. The linkage mechanism includes a first link, a second link, and a mounting frame for mounting the gripping manipulator. One end of the first link is hinged to the mounting platform, and the other end is hinged to the mounting frame. One end of the second link is hinged to the mounting platform, and the other end is hinged to the mounting frame. The mounting platform, the first link, the mounting frame, and the second link can form a four-bar linkage. The drive assembly includes a motor assembly fixed on the mounting platform. The motor assembly can drive the first link or the second link to rotate, causing the four-bar linkage to deform, thereby adjusting the position of the mounting frame and the gripping manipulator. The gripping manipulator's gripping mechanism can be moved to a position corresponding to the workpiece for material handling.

[0004] Existing backlight product positioning robot picking mechanisms use negative pressure adsorption to move workpieces. During operation, dust or water stains on the workpiece surface can cause slippage between the picking mechanism and the workpiece. This slippage prevents the robot from accurately placing the workpiece in the intended position, affecting the product's positioning accuracy. This can lead to the accumulation of errors in subsequent processing or assembly, ultimately impacting the quality and performance of the final product. Due to slippage, the robot may need to attempt to successfully pick up the workpiece multiple times, resulting in longer production cycles and reduced production efficiency. Therefore, we propose a new backlight product positioning robot picking mechanism. Utility Model Content

[0025] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0026] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the present invention provides a backlight product positioning robot material handling mechanism, which includes a cabinet 1, cabinet doors installed on all four sides of the cabinet 1, a robot arm 2 installed inside the cabinet 1, and a frame 3 fixedly installed inside the cabinet 1. Two spaced-apart rollers 4 are rotatably mounted inside the frame 3. A conveyor belt 5 is installed between the two rollers 4. A first motor 6 is fixedly mounted on the frame 3. The output shaft of the first motor 6 is fixedly connected to one side of the roller 4. Two spaced-apart limit plates 7 are provided at the upper end of the conveyor belt 5. The limit plates 7 are fixedly connected to the frame 3. A movable seat 8 is provided at the upper end of the conveyor belt 5. A mounting seat 9 is provided at the lower end of the movable seat 8. Two spaced-apart spring telescopic rods 10 are fixedly mounted at the bottom of the movable seat 8. The movable ends of the spring telescopic rods 10 are fixedly connected to the mounting seat 9. A cotton roller 11 is rotatably mounted on the mounting seat 9. A second motor 12 is fixedly mounted on the mounting seat 9. The output shaft of the second motor 12 is fixedly connected to the cotton roller 11. A moving mechanism connected to the movable seat 8 is provided on the frame 3. The moving mechanism is used to drive the cotton roller 11 to move horizontally.

[0027] The moving mechanism includes two guide rods 13 that pass through the movable seat 8. The ends of the guide rods 13 are fixedly connected to the frame 3. A lead screw 14 is rotatably mounted on the frame 3, passing through the movable seat 8 and threadedly connected to it. A third motor 15 is fixedly mounted on the frame 3, and the output shaft of the third motor 15 is fixedly connected to the lead screw 14. A magnet 16 is fixedly mounted on the mounting base 9, and an electromagnet 17 opposite to the magnet 16 is fixedly mounted on the bottom of the movable seat 8. By placing the workpiece on the conveyor belt 5, the first motor 6 drives the rotating roller 4 to rotate, which in turn drives the conveyor belt 5 to operate and transport the workpiece. When the workpiece moves to the limit plate 7, the first motor 6 stops. The limit plate 7 limits the workpiece to the side. The electromagnet 17 applies a repulsive force to the magnet 16, which causes the cotton roller 11 on the mounting base 9 to move toward the workpiece and be in contact with it. The second motor 12 drives the cotton roller 11 to rotate, which removes dust and moisture from the surface of the workpiece. The third motor 15 drives the lead screw 14 to rotate, which causes the movable seat 8 to move back and forth along the guide rod 13, and causes the cotton roller 11 on the mounting base 9 to move back and forth on the workpiece, thereby performing a comprehensive cleaning of different positions on the surface of the workpiece.

[0028] The frame 3 has a rotatable brush roller 18 and a fixed fourth motor 19. The output shaft of the fourth motor 19 is fixedly connected to the brush roller 18, which is located on one side of the cotton roller 11. A vacuum cleaner 20 is mounted on the frame 3, with its suction port located directly below the brush roller 18. When the cotton roller 11 is covered with dust and the cleaning effect is reduced, the third motor 15 drives the movable seat 8 to move towards the brush roller 18, bringing the cotton roller 11 into contact with it. The fourth motor 19 then drives the brush roller 18 to rotate, allowing it to clean the surface of the cotton roller 11. The brush roller 18 removes the dust adhering to the surface of the cotton roller 11, and the dust detaches from the cotton roller 11. The vacuum cleaner 20 then absorbs the detached dust, thus preventing dust from being stirred up.

[0029] Working principle: By placing the workpiece on the conveyor belt 5, the first motor 6 drives the rotating roller 4 to rotate, which in turn drives the conveyor belt 5 to move and transport the workpiece. When the workpiece moves to the limit plate 7, the first motor 6 stops. The limit plate 7 limits the workpiece to the side. The electromagnet 17 applies a repulsive force to the magnet 16, which causes the cotton roller 11 on the mounting base 9 to move toward the workpiece and be in contact with it. The second motor 12 drives the cotton roller 11 to rotate, which can remove dust and moisture from the surface of the workpiece. Then, the third motor 15 drives the lead screw 14 to rotate, which can make the movable seat 8 move back and forth along the guide rod 13, and make the cotton roller 11 on the mounting base 9 move back and forth on the workpiece, thereby performing a comprehensive cleaning of different positions on the surface of the workpiece.

[0030] When the cleaning effect is reduced due to excessive dust accumulation on the cotton roller 11, the third motor 15 drives the movable seat 8 to move towards the brush roller 18, bringing the cotton roller 11 into contact with the brush roller 18. The fourth motor 19 then drives the brush roller 18 to rotate, allowing it to clean the surface of the cotton roller 11. The brush roller 18 removes the dust adhering to the surface of the cotton roller 11, and the dust detaches from the cotton roller 11. The dust is then absorbed by the vacuum cleaner 20, thus preventing dust from being stirred up. Afterwards, the conveyor belt 5 transports the workpiece to the robot arm 2 for workpiece loading.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
