Description

Technical Field

[0001] This invention belongs to the field of light guide plate assembly technology, and particularly relates to a device for stacking, assembling, leveling, and cleaning light guide plates. Background Technology

[0002] Light guide plates are made of optical-grade acrylic or PC sheets, combined with high-tech materials and specific engraving and printing techniques. They transform linear light sources into surface light sources. Lighting fixtures made by combining light guide plates with lamps have excellent decorative effects, making light guide plates increasingly widely used in daily life. Existing finished light guide plates are relatively small in size. When manufacturing large-sized lighting fixtures, several small-sized light guide plates need to be assembled or stacked together. During the assembly of light guide plates, since the picking, alignment, and assembly work are basically done manually, it is easy to cause inaccurate alignment of the light guide plates, which affects both the assembly efficiency and the assembly quality.

[0003] In the prior art, patent document with publication number "CN221849274U" discloses a splicing device for assembling a lamp panel, including: a main mounting base and a secondary mounting base; a support plate is fixedly connected to the top of both the main mounting base and the secondary mounting base, a crossbeam is fixedly connected to one end of the support plate, a groove is formed on the outer wall of the crossbeam, two lead screw sleeves are slidably connected in the groove of the crossbeam, a first electric cylinder and a second electric cylinder are fixedly connected to one end of the two lead screw sleeves respectively, an external base is fixedly connected to the extension end of both the first electric cylinder and the second electric cylinder, and two symmetrical suction cup heads are fixedly connected to the top of the external base. Each component is fixedly connected to a limiting frame, and a connecting sleeve is fixedly connected to the outer wall of the limiting frame. A baffle is slidably connected to the inner wall of the connecting sleeve. Using this patented technology, an automated mechanical device is set up to pick up the light guide plate, which improves the assembly efficiency of the light guide plate. However, when multiple light guide plates are stacked and assembled, due to the smooth surface of the light guide plate, misalignment is easy to occur between adjacent light guide plates, affecting the stacking accuracy of the light guide plates. In addition, during the splicing process, dust from the external environment can easily penetrate into the surface of the light guide plate, resulting in gaps in the assembled light guide plate. Light will produce abnormal refraction at the joints of the combined light guide plates, affecting the normal application of the assembled light guide plate. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a device for stacking, assembling, leveling, and cleaning light guide plates.

[0009] The light guide plate stacking, leveling, and cleaning device also includes a longitudinal guide rod, the two ends of which are fixedly connected to the support, and the longitudinal guide rod also passes through the longitudinal slider.

[0010] The support is also fixedly connected to the main motor, and the output shaft of the main motor is fixedly connected to the ball screw.

[0011] The light guide plate stacking, leveling, and cleaning device also includes a rotating shaft, a pair of transverse sliders, a pair of connecting rods, and an alignment push plate. The rotating shaft is mounted on the bottom surface of the support plate using rolling bearings. One end of the rotating shaft is provided with a first thread, and the other end of the rotating shaft is provided with a second thread. The directions of the first thread and the second thread are opposite to each other.

Detailed Implementation

[0018] The technical solution of the present invention will be further described below with reference to the accompanying drawings, but the scope of protection claimed is not limited thereto; This invention provides a device for the stacking, leveling, and cleaning of light guide plates, such as... Figures 1 to 5As shown, it includes a support plate 1 and a sliding plate 2. The top surface of the support plate 1 is provided with a suction cup 3, the bottom surface of the support plate 1 is provided with an air pump 4, and the upper part of the support plate 1 is also provided with a sliding plate 2. The surface of the sliding plate 2 is provided with an air nozzle 5. One end of the air nozzle 5 is aligned with the upper part of the suction cup 3, and the other end of the air nozzle 5 is connected to one end of the air guide pipe 6. The other end of the air guide pipe 6 is connected to the air outlet of the air pump 4, and the air inlet of the air pump 4 is connected to the suction cup 3. A filter plate 7 is also provided inside the air guide pipe 6.

[0019] Using the technical solution provided by this invention, when stacking or assembling multiple light guide plates, an air pump draws air from the suction cup, creating a negative pressure vacuum within the suction cup. This allows the light guide plate to be adsorbed onto the surface of the support plate in a stable posture, facilitating the positioning of the light guide plate. The air drawn by the air pump is then purified by a filter plate before being sprayed onto the surface of the light guide plate. On the one hand, this allows the airflow drawn by the air pump to be reused, and the pressure generated by the airflow makes the posture and positioning of the light guide plate more stable. On the other hand, the airflow can remove powder and impurities from the surface of the light guide plate, keeping the surface clean and preventing dust from falling onto the surface of the light guide plate from the external environment, thus reducing optical defects inside the assembled light guide plate. In addition, the pressure generated by the airflow can make the surface of the light guide plate bear more uniform pressure, allowing adjacent light guide plates to adhere under uniform pressure, preventing local warping of the light guide plate, and preventing the surface of the light guide plate from being damaged by rigid pressure, thereby improving the flatness of the stacked light guide plates.

[0020] Specifically, the support plate 1 is rectangular in shape, and there are multiple suction cups 3 arranged in a linear array along the edge contour of the support plate 1.

Both ends of the cleaning roller 8 are mounted on the vertical slider 10 using rolling bearings. There are multiple air nozzles 5 distributed on the left and right sides of the cleaning roller 8. The vertical shaft 9 also passes through a spring 11, which is clamped between the vertical slider 10 and the sliding plate 2. By adopting the technical solution of this invention, when stacking and assembling two light guide plates or assembling multiple light guide plates, the rotation of the cleaning roller 8 can remove debris from the surface of the light guide plate, further reducing optical defects inside the assembled light guide plate. The elasticity of the spring 11 supports the cleaning roller 8, adjusting the pressure exerted by the cleaning roller 8 on the surface of the light guide plate and preventing damage to the surface of the light guide plate under pressure.

[0021] In addition, the light guide plate stacking, assembling, leveling, and cleaning device also includes a ball screw 12. Both ends of the ball screw 12 are mounted on a support 13 using rolling bearings. The support 13 is fixedly connected to a base 14, and the base 14 is fixedly connected to one end of a column 15.

The support 13 is also fixedly connected to a main motor 18, and the output shaft of the main motor 18 is fixedly connected to the ball screw 12. When the main motor 18 is running, the cleaning roller 8 moves back and forth along the length of the light guide plate, thereby thoroughly removing debris from the surface of the light guide plate and reducing optical defects inside the assembled light guide plate.

[0022] In addition, the light guide plate stacking, leveling, and cleaning device also includes a rotating shaft 19, a pair of transverse sliders 20, a pair of connecting rods 21, and an aligning edge push plate 22. The rotating shaft 19 is mounted on the bottom surface of the support plate 1 using rolling bearings.

The rotation directions of the first thread 23 and the second thread 24 are opposite to each other. Both ends of the rotating shaft 19 are respectively screwed to the pair of transverse sliders 20 through the first thread 23 and the second thread 24. The pair of transverse sliders 20 are also fixedly connected to one end of the pair of connecting rods 21, and the other ends of the pair of connecting rods 21 are respectively fixedly connected to one side of the aligning edge push plate 22. The other sides of the aligning edge push plate 22 are opposite to each other and are arranged on the left and right sides of the support plate 1. Preferably, the connecting rod 21 is U-shaped.
