Description

Technical Field

[0001] The utility model relates to the technical field of flipping equipment, in particular to a light guide plate flipping device. Background Art

[0002] A light guide plate is an optical element used to guide and evenly distribute light. It is widely used in various lighting and display devices. Since protective films are provided on both sides of the light guide plate, when processing the light guide plate, the protective film on one side of the light guide plate must be torn off first, and then hot pressing transfer is performed. After hot pressing transfer, the protective film is affixed to the hot pressing transfer surface again. The light guide plate is then moved to the flipping device, positioned by adjusting the column, and adsorbed by the adsorption component. The light guide plate is then driven to flip 180 degrees by the flip cylinder. The light guide plate is then taken down by a robot for packaging to facilitate subsequent direct use.

[0003] When the light guide plate is positioned by adjusting the column, the adjusting column will contact the side of the light guide plate many times. After the contact, the light guide plate will cause different degrees of wear on the side of the light guide plate. After long-term use, wear marks of different sizes will be left on the adjusting column, resulting in inaccurate positioning of the light guide plate by the adjusting column. Therefore, the present application provides a light guide plate flipping device to meet the needs. Utility Model Content

[0031] like Figure 3 As shown, in this embodiment, the adjustment component 18 includes a circular hole 19 formed on the square plate 15, and a receiving hole 20 is formed on the inner wall of the circular hole 19. An insert block 21 is slidably connected to the inner wall of the receiving hole 20, and a spring 22 is fixed between the insert block 21 and the receiving hole 20. A connecting rod 28 is provided on the inner wall of the circular hole 19, and a plurality of slots 23 are formed on the circumferential surface of the connecting rod 28. The insert block 21 abuts against the inner wall of the slot 23. Through the adjustment component 18, the adjustment column 16 can be rotated and adjusted, so that the adjustment column 16 can be fully used.

[0032] like Figure 3 As shown, in this embodiment, the fitting surfaces of the plug 1 21 and the slot 1 23 are provided with an inclined guide surface 29, and the slot 1 23 is provided with a guide surface adapted to the guide surface 29 at the position corresponding to the guide surface 29. The cooperation between the guide surface 29 and the guide surface can prevent the plug 1 21 from getting stuck, and is smoother in use.

[0033] like Figure 3As shown, in this embodiment, a second receiving hole 24 is provided on the first inserting block 21, and a second inserting block 25 is slidably connected to the inner wall of the second receiving hole 24. A second spring 27 is fixed between the second inserting block 25 and the second receiving hole 24.

The curved surface on the second plug-in block 25 can guide itself to avoid getting stuck during movement.

[0034] like Figure 1-Figure 3 As shown, in this embodiment, a bracket 9 is fixed on the angle iron 7, an electric push rod 10 is fixed on the bracket 9, a connecting piece 11 is fixed to the output end of the electric push rod 10, and a limiting column 12 is fixed on the connecting piece 11. The limiting column 12 is driven to move by the electric push rod 10, and the limiting column 12 can be adjusted to adapt to light guide plates of different sizes. By setting the limiting column 12, the light guide plate can be positioned, so that the positioning of the light guide plate is more accurate.

[0035] like Figure 3 As shown, in this embodiment, a rubber sleeve is fixedly sleeved on the surface of the limiting post 12. After the rubber sleeve is provided, hard contact between the light guide plate and the limiting post 12 is avoided, thereby protecting the light guide plate.

[0036] like Figure 1 、 Figure 2 and Figure 4 As shown, in this embodiment, a circular plate 17 is fixed to the top of the adjusting column 16, and anti-slip stripes are provided on the circumferential surface of the circular plate 17. By providing the circular plate 17, the contact area between the hand and the adjusting column 16 is increased. Increasing the adjusting column 16 by the circular plate 17 is more labor-saving, and the anti-slip stripes on the side of the circular plate 17 can increase the friction between the hand and the adjusting column 16 to prevent the hand from slipping during rotation.

[0037] Working principle: according to the size of the light guide plate, start the electric push rod 10 on the bracket 9, the electric push rod 10 drives the connecting piece 11 to move, and the connecting piece 11 drives the limit column 12 to adjust until it is adjusted to the appropriate position. When the light guide plate is hot-pressed and transferred and the film is pasted, the light guide plate is placed on the round roller 8 on the angle iron 7, and then the light guide plate is moved under the adsorption component 6, and the light guide plate is placed against the limit column 12, and then the electric push rod 2 14 on the middle plate 13 is started. The electric push rod 2 14 will drive the square plate 15 to move, and the square plate 15 will drive the adjustment column 16 to move through the connecting rod 28. During the movement of the adjustment column 16 to the middle, the adjustment column 16 positions the light guide plate so that the light guide The plate is directly below the adsorption component 6, and then the lifter 2 is started. The lifter 2 will drive the rotating cylinder 3 to move downward, and the rotating cylinder 3 will drive the round rod 4 to move downward, and the round rod 4 will drive the rotating frame 5 to move downward, and the rotating frame 5 will drive the adsorption component 6 to move downward. After the adsorption component 6 moves to the light guide plate, the light guide plate is sucked by the adsorption component 6, and then the lifter 2 is started again. The light guide plate is driven upward by the lifter 2, the rotating cylinder 3, the round rod 4, the rotating frame 5 and the adsorption component 6. When the upward movement distance exceeds the width of the light guide plate, the rotating cylinder 3 is started. After the rotating cylinder 3 rotates, it drives the light guide plate to rotate 180 degrees. Finally, the light guide plate can be removed by the manipulator;

[0038] When the adjusting column 16 is used for a long time, the surface of the adjusting column 16 will be worn to varying degrees. At this time, hold the circular plate 17 with your hand and rotate the circular plate 17. The circular plate 17 drives the adjusting column 16 to rotate, and the adjusting column 16 drives the connecting rod 28 to rotate. At this time, the plug block 25 will move from the current slot 26 to the adjacent slot 26, and the spring 27 in the receiving hole 24 drives the plug block 25 to be inserted into the slot 26, so that one side of the hexagonal adjusting column 16 is rotated to the adjacent side. Subsequently, until the adjusting columns 16 on the same plane are all worn, the adjusting column 16 can be moved up or down. During movement, the plug block 1 21 moves and is recovered into the receiving hole 1 20 through the guide surface 29 until the adjacent slot 1 23 moves to the position of the plug block 1 21. At this time, the spring 1 22 drives the plug block 1 21 to be inserted into the slot 1 23. At this time, the adjusting column 16 can continue to be used.

To provide a thorough understanding of the present invention, specific details are described in detail in the preferred embodiments of the present invention above, but those skilled in the art can fully understand the present invention without these detailed descriptions.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
