Description

Technical Field

[0001] This invention relates to the field of edge grinding technology, specifically to an edge repair and grinding device for LED backlight panels. Background Technology

[0002] Backlight boards are light sources used to ensure that the back of an LCD screen emits light. During the production of backlight boards, the edges of the backlight boards need to be polished to make them smooth. Current LED backlight board edge polishing devices generally clamp the backlight board directly and then use polishing components to polish it. However, during the polishing process, the temperature of the waste chips rises due to the grinding debris, and they fly around randomly, which affects the operating environment and may even pose a safety hazard to the operator.

[0003] In existing technologies, a protective cover is used to directly protect the grinding components and work inside it. This requires the operator to reach into the protective cover to place or retrieve parts, and then the clamping components are activated to clamp them.

[0004] However, due to the aforementioned structure, users need to insert their bodies into the device during use, which poses certain safety hazards. Furthermore, a separate drive component is required for fixation, significantly increasing the cost of using the device and making it inconvenient. Consequently, the overall work efficiency is greatly reduced. Summary of the Invention

The mounting plate 23 is connected to the moving plate 24 through the screw 25, and the moving plate 24 slides with the guide rod 26. By utilizing the action of the driver, screw 25, guide rod 26, and moving plate 24, the grinding assembly can be moved to cooperate with subsequent parts to complete the work.

[0040] Please see Figure 5 and Figure 6 The polishing assembly includes a motor 27 and a polishing wheel 28. The polishing wheel 28 is rotatably connected inside the movable plate 24, and the motor 27, which cooperates with the polishing wheel 28, is installed on the outside of the movable plate 24. The polishing task can be easily completed by utilizing the action of the motor 27 and the polishing wheel 28.

[0041] Please see Figure 5 and Figure 6The air supply assembly includes an air supply unit 6 and a jet nozzle 29.

[0042] Please see Figure 1 and Figure 4 The transmission assembly includes a toothed plate 8, a gear 9, and a rotating shaft 21. The toothed plates 8 are symmetrically arranged on one side of the upper mounting frame 3. The rotating shaft 21 connects the collection box 1 and the baffle 10. Each rotating shaft 21 has a gear 9 extending to the outside of the collection box 1 at one end, and each gear 9 meshes with the corresponding toothed plate 8. By utilizing the toothed plate 8, the gear 9, and the rotating shaft 21, the downward force of the lifting assembly is easily transmitted to the baffle 10 so that the baffle 10 can be opened or closed to complete subsequent work.

[0043] Please see Figure 5 and Figure 6 The top two ends of the collection box 1 are provided with guide posts 4 that cooperate with the upper mounting frame 3. The guide posts 4 are used to ensure the stability of the upper mounting frame 3 when it moves. The inner wall of the collection box 1 is symmetrically provided with inclined surfaces 22. The inclined surfaces 22 are used to facilitate the opening of the baffle 10 and avoid interference.

[0044] The working principle of this invention is as follows: In use, the grinding assembly is first started, that is, the motor 27 is started, which drives the grinding wheel 28 to work. Then, the backlight board is placed directly in the placement frame 14 and supported by multiple sets of support plates 19. Then, the moving clamping mechanism is started. Specifically, the moving assembly is started, and then the clamping assembly is driven to work. That is, the third cylinder 11 is started, which drives the connecting plate 12 to move. Under the action of the moving rod 13, the placement frame 14 is moved along the support plate 19 to the bottom of the grinding assembly. During the movement, after part of the clamping assembly comes into contact with the side plate 7, specifically after one end of the pressure rod 17 comes into contact with the side plate 7, the pressure rod 17 is squeezed and moves, which in turn drives the first pressure plate 16 to move. Then, in cooperation with the second pressure plate 20, the backlight board is clamped and fixed, thereby avoiding the need to reach into the equipment when picking up and placing it, reducing certain safety hazards.

[0045] Once the placement frame 14 is fully within the coverage area of ​​the upper mounting frame 3, the lifting assembly is activated, i.e., the first cylinder 2 is activated, which drives the upper mounting frame 3 to move downwards until the lower end of the upper mounting frame 3 contacts the collection box 1, at which point the operation stops. At the same time, the meshing of the toothed plate 8 and the gear 9 drives the corresponding rotating shaft 21 to rotate, thereby opening the corresponding baffle 10. With the design of the inclined surface 22, interference is avoided when the baffle 10 is opened, and waste chips are easily guided down. Furthermore, during grinding, the upper mounting frame 3 and the collection box 1 form a protective cover, preventing waste chips from splashing out and causing damage to the operator and the environment.

[0046] Next, using the action of the second cylinder 5, the mounting plate 23 and the grinding assembly are moved downwards until the grinding assembly, which is in operation, contacts the surface of the backlight panel and then stops. Then, the horizontal moving assembly is started, that is, the driver is started, which drives the screw 25 to rotate. With the action of the guide rod 26, the moving plate 24 moves along the direction of the screw 25, thereby grinding the edge of the backlight panel and the surface of the backlight panel, making the entire working surface smooth and burr-free, thereby improving the overall work efficiency. At the same time, the air supply 6, which is in operation, cleans the surface of the backlight panel under the action of the air nozzle 29 to ensure that the surface of the backlight panel is clean.

[0047] After polishing is completed, the lifting assembly is activated to move the polishing assembly away from the backlight panel, and the baffle 10 is closed to prevent waste from splashing onto the support plate 19 when cleaning the collection box 1, which would affect subsequent work. Then the polishing assembly is stopped, and the moving clamping mechanism is activated to send out and release the backlight panel. Finally, it is taken out to complete the work. Then the next set is placed, and this cycle is repeated.

[0048] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the invention and are not intended to limit it. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
