[0002] As a new type of light source, LED (Light Emitting Diode) is widely used in lighting, display and other fields. However, due to certain process errors in the manufacturing process of LED light boards, the optical performance of LED light boards may deviate, one of which is the polarization correction of LEDs.

[0003] At present, some technical solutions have been proposed for the problem of LED polarization correction. Among them, a common solution is to use a clamp to fix the LED light board and achieve polarization correction by accurately controlling the clamping force and position. However, there are some problems with the existing technical solutions.

[0004] Horizontal offset problem: During the clamping process, the light board may easily deviate horizontally due to unstable fixture fixation or slight deformation of the light board itself, thus affecting the accuracy and stability of polarization correction.

[0005] Extrusion damage problem: Existing clamps often use hard materials or directly contact the surface of the light board when clamping the light board, which can easily cause extrusion damage to the light board and reduce the life and performance of the light board.

[0006] Adaptability issue: Existing fixtures are often only suitable for LED light panels of a specific size and cannot meet the needs of light panels of different sizes.

[0007] Inconvenience in use: The process of installing and fixing the fixture requires complicated operating steps, which is not convenient and quick enough.

[0008] To this end, we propose a fixture for LED polarization correction. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Embodiment: A fixture for LED polarization correction, such as Figure 1-Figure 3 As shown, it includes two groups of mounting frames 1, a lamp board is arranged between the two groups of mounting frames 1, a driving assembly for horizontal movement is arranged on the top of the mounting frame 1, a clamping assembly is arranged between the two mounting frames 1, the clamping assembly includes a lower clamping plate 2 located on the mounting frame 1, the lower clamping plate 2 is an L-shaped structure, an upper clamping plate 3 corresponding to the upper and lower ends is arranged above the lower clamping plate 2, the upper clamping plates 3 are all insulating baffles of T-shaped structure, a liftable first telescopic rod 301 is arranged between the bottom of the upper clamping plate 3 and the top of the lower clamping plate 2, and a detachable anti-deviation baffle is arranged between the two lower clamping plates 2, and the two sides of the lamp board are positioned by the anti-deviation baffle.

[0032] The anti-deviation baffle includes a limit plate body 501 located between the two lower clamping plates 2. The two limit plate bodies 501 are connected to the ends away from each other with a threaded rod 5 that passes through the vertical end of the lower clamping plate 2, and each threaded rod 5 is threadedly connected to two nut blocks 502. The two nut blocks 502 are located on both sides of the lower clamping plate 2. The two limit plate bodies 501 are controlled to extend and retract horizontally inside the mounting frame 1 by rotating the two nut blocks 502.

[0033] Each of the limiting plate bodies 501 is composed of multiple layers of elastic baffles, and the elastic limiting plate body 501 will not cause extrusion and wear to the side of the lamp board.

[0034] A row of elastic buffer protrusions 4 are connected to the adjacent ends of the lower clamping plate 2 and the upper clamping plate 3, and each of the buffer protrusions 4 is a T-shaped insulating block. By arranging a row of elastic buffer protrusions 4 between the lower clamping plate 2 and the upper clamping plate 3, when the lamp board is clamped and fixed up and down, no extrusion damage will be caused to the upper and lower surfaces of the lamp board, and a role of elastic protection will be played for the contact ends on the lamp board.

[0035] The driving assembly includes a connecting rod 6 located at the top of the mounting frame 1, and the two connecting rods 6 are both L-shaped structures, and the ends of the two connecting rods 6 that are away from each other are connected to a retractable second telescopic rod 601, and the free ends of the two second telescopic rods 601 are both sleeved with a flange ring 602; by arranging the second telescopic rod 601 on the driving assembly, the two clamping devices can be controlled to clamp and fix LED light panels of different widths, and the flange ring 602 arranged on the second telescopic rod 601 facilitates the installation of the clamp on the two side baffles of the processing table.

[0036] The working principle of the utility model is as follows: by arranging a horizontal corresponding anti-drift baffle on the clamping assembly, when the lamp board is fixed by the clamping assembly, the two sides of the lamp board cooperate with the anti-drift baffle for positioning, to prevent the lamp board clamped up and down from being collided or horizontally deviated when it is not clamped stably.

[0037] The LED light board is clamped and fixed up and down by the clamping assembly, and an anti-deviating baffle is arranged between the two lower clamping plates. When the light board is fixed by the clamping assembly, the two sides of the light board are accurately positioned, thereby avoiding the horizontal deviation of the light board during the clamping process. In addition, the device also adopts an elastic buffer bump 4 and a multi-layer elastic limiting plate body 501 to ensure that the upper and lower surfaces of the light board will not be squeezed and damaged when the light board is clamped and fixed up and down.

[0038] Compared with the existing technology, the advantages of this device are mainly reflected in the following aspects:

[0039] The setting of the anti-deviation baffle can accurately position the light board, avoiding the horizontal deviation of the light board during the clamping process, and improving the clamping accuracy and stability;

[0040] The elastic buffer bump 4 and the multi-layer elastic limiting plate body 501 can protect the surface of the light board from being squeezed and damaged, effectively extending the service life of the light board;

[0041] The retractable design of the clamping assembly makes the device suitable for LED light panels of different widths, improving flexibility and adaptability;

[0042] The design of the driving assembly and flange ring 602 of the device makes it easy to install the fixture on the two side baffles of the processing table, thereby improving the convenience of use.
