Detailed Implementation

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] An adjustable edge-fitting fixture for LED light guide plates, such as Figures 1-6 As shown, the device includes a placement base 1, a guide rail 2, a slide 3, an electromagnetic lock 4, a side positioning plate 5, a horizontal indicator post 6, a blanking plate 7, a locking pin 8, a spring 9, and a top blanking mechanism. The guide rail 2 is connected to the upper front of the placement base 1. Slides 3 are slidably connected to both sides of the guide rail 2. Electromagnetic locks 4 are connected to each slide 3, and the electromagnetic locks 4 magnetically engage with the guide rail 2. Side positioning plates 5 are connected to the top of each slide 3. Horizontal indicator posts 6 are slidably connected to each side positioning plate 5. Blanking plates 7 are slidably connected to each horizontal indicator post 6. Locking pins 8 are slidably connected to each blanking plate 7, and the locking pins 8 press against the horizontal indicator posts 6. A spring 9 connects the locking pins 8 and the blanking plate 7. A top blanking mechanism is located on the upper part of the blanking plate 7. When the LED light guide plate is placed on the placement base 1, the slide 3 moves on the guide rail 2, causing the side positioning plate 5 to conform to the LED light guide plate. The LED light guide plate can be positioned on both sides. After the side positioning plate 5 is in place, the electromagnetic lock 4 and the guide rail 2 are magnetically attracted to fix the slide 3, making the slide 3 unable to move. At this time, the blank plate 7 is located in front of the LED light guide plate. By sliding the blank plate 7, the blank position of the two sides of the LED light guide plate is controlled. When the LED light guide plate is attached to the edge, the adhesive strip is pasted between the blank plates 7. The blank plate 7 slides on the horizontal indicator post 6. When the blank plate 7 slides, the locking pin 8 is pulled down to disengage the locking pin 8 from the horizontal indicator post 6, and then the blank plate 7 can be moved. After the blank plate 7 is moved and adjusted, the locking pin 8 is released. At this time, the spring 9 returns, and the locking pin 8 is reset and engaged with the horizontal indicator post 6 to fix the blank plate 7. After the blank plate 7 is fixed, the blank area is blocked, so that the adhesive strip can only be pasted between the blank plates 7, thus achieving the purpose of blanking.

[0022] The horizontal indicator column 6 is equipped with a scale groove to facilitate the reference of the blanking distance;

[0023] It also includes a positioning grating 10. The whiteboard 7 is connected to the back of the positioning grating 10. The positioning grating 10 can emit multiple parallel rays. The spacing between the rays is consistent with the width of the adhesive strip of the booth, which facilitates the guidance of adhesive strip pasting.

[0024] The top blanking mechanism includes a sliding block 11, a top positioning frame 12, a telescopic tube 13, a vertical indicator post 14, and a blanking mark 15. The sliding block 11 is slidably connected to the upper part of the blanking board 7, and the top positioning frame 12 is rotatably connected to the sliding block 11. The telescopic tube 13 is connected to the bottom of the sliding block 11, and the vertical indicator post 14 is slidably connected to the telescopic tube 13. The blanking mark 15 is connected to the bottom of the vertical indicator post 14. The sliding block 11 controls the movement of the top positioning frame 12, thus moving the top positioning frame 12. Reach the top of the LED light guide plate, then rotate the top positioning frame 12 to make the top positioning frame 12 contact the top surface of the LED light guide plate, support and fix the sliding block 11, then pull the white mark 15, the white mark 15 controls the vertical indicator column 14 to move up and down in the telescopic tube 13, observe the distance indicated by the vertical indicator column 14, and make the white mark 15 in a suitable position. The height of the bottom surface of the white mark 15 is the highest point when the adhesive strip is attached, which is convenient for leaving white space on the upper part of the LED light guide plate.

[0025] The top positioning frame 12 is equipped with a support column, which is used to contact the top surface of the stacked LED conduit plate and form a support when in contact, thus providing positioning support for the slider.

[0026] The vertical indicator column 14 is also equipped with a scale groove to facilitate the reference of the blank space distance;

[0027] In use, the LED light guide plate is placed on the placement base 1, and the slide 3 moves on the guide rail 2 until the side positioning plate 5 is attached to both sides of the LED light guide plate. After the side positioning plate 5 is in place, the electromagnetic lock 4 is magnetically attracted to the guide rail 2 to fix the slide 3, preventing it from moving. At this time, the blanking plate 7 is located in front of the LED light guide plate. By sliding the blanking plate 7, the blanking position on both sides of the LED light guide plate is controlled. When the LED light guide plate is attached to the edge, the adhesive strip is placed between the blanking plates 7. The blanking plate 7 slides on the horizontal indicator post 6. When the blanking plate 7 slides, the locking pin 8 is pulled down to disengage from the horizontal indicator post 6, allowing the blanking plate 7 to move. After the blanking plate 7 is moved and adjusted, the locking pin 8 is released. At this time, the spring 9 returns, causing the locking pin 8 to reset and engage with the horizontal indicator post 6 to fix the blanking plate 7. After the blanking plate 7 is fixed, it blocks the blanking area, so that the adhesive strip can only stick to the blanking plate. The strips are placed between the blanking boards 7 to achieve the purpose of leaving blank space. After the side blanking position is adjusted, the sliding block 11 is controlled. The sliding block 11 slides up and down on the blanking board 7. The sliding of the sliding block 11 will control the movement of the top positioning frame 12. Move the top positioning frame 12 to the top of the LED light guide plate, and then rotate the top positioning frame 12 to make it contact the top surface of the LED light guide plate to support and fix the sliding block 11. Then pull the blanking mark 15. The blanking mark 15 controls the vertical indicator post 14 to move up and down in the telescopic tube 13. Observe the distance indicated by the vertical indicator post 14 to make the blanking mark 15 in a suitable position. The height of the bottom surface of the blanking mark 15 is the highest point when the adhesive strip is attached to the edge, which facilitates the blanking assistance of the upper part of the LED light guide plate. After the side and top blanking control adjustment is completed, the LED light guide plate can be attached to the edge. After the edge is attached, the LED light guide plate can be removed from the placement seat 1.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
