Description

Technical Field

[0001] The invention relates to the technical field of polarizer processing, and in particular to a real-time thickness detection device used for polarizer processing. Background Art

[0002] In the field of polarizer processing, with the rapid development of the electronic equipment market, increasingly stringent requirements are placed on the quality and production efficiency of polarizers. The thickness of the polarizer, as a key quality indicator, directly affects its optical performance and assembly accuracy in electronic equipment. Traditional polarizer thickness detection and processing equipment often have many limitations. In terms of detection, many early detection devices use manual measurement or simple mechanical measuring tools. This method not only has an extremely slow detection speed, but is also easily interfered by human factors, resulting in uneven measurement accuracy, which is difficult to meet the needs of large-scale, high-precision production.

[0003] However, in the actual use of the above-mentioned equipment, during the clamping and processing, the clamping mechanism of traditional equipment is usually relatively simple, and can generally only achieve clamping in a single direction or a limited number of directions. For workpieces such as polarizers that have various shapes and high requirements for flatness and stability, it is impossible to provide uniform and reliable clamping force, which may cause displacement, deformation or vibration of the polarizer during the processing, which will not only damage the surface quality of the polarizer, but also further affect the accuracy of thickness detection.

[0004] Therefore, we proposed a real-time thickness detection device for polarizer processing. Summary of the invention

[0005] The object of the present invention is to provide a real-time thickness detection device for polarizer processing to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions: A real-time thickness detection device for polarizer processing includes a main body, a support leg is fixedly connected to the lower part of the main body, a workbench is arranged on the main body, a support plate is fixedly connected to the main body, a grinding device is arranged on the support plate, and a swing clamping assembly is arranged on the support plate, and the swing clamping assembly includes: The motor is fixedly mounted on the support plate, the motor is fixedly connected to a rotating rod, the rotating rod is fixedly connected to a swing block, the swing block is fixedly connected to a short plate, the short plate is fixedly mounted to an electric push rod, and the piston end of the electric push rod is fixedly connected to a square block; A clamping base plate, the square block is fixedly connected with the clamping base plate, a slide groove is provided on the clamping base plate, a clamping block is slidably connected to the slide groove, a support rod is fixedly connected to the clamping block, a fixing rod is fixedly connected to the support rod, and an electric telescopic rod is fixedly connected to the fixing rod; An L-shaped block is rotatably connected to the clamping block, a rotating block is rotatably connected to the L-shaped block, a fixing column is fixedly connected to the clamping bottom plate, and the rotating block is rotatably connected to the fixing column.

[0007] Preferably, the slide grooves are provided in multiple groups, and the multiple groups of slide grooves are arranged in a circular array with equal spacing with the center of the circular cross-section of the fixed column as the center of the array. When clamping the polarizer, the multiple groups of slide grooves can provide sliding tracks in multiple directions for the clamping blocks, so that the clamping blocks can apply clamping force to the polarizer from different angles. When the shape of the polarizer is irregular or is subjected to external forces in different directions during processing, each clamping block can flexibly adjust its position along the corresponding slide groove, so as to evenly disperse the clamping force, effectively avoiding damage to the polarizer or unstable clamping due to excessive local force.

[0008] Preferably, the L-shaped blocks are provided in multiple groups, and the multiple groups of L-shaped blocks are arranged in a circular array with equal spacing with the center of the circular cross-section of the fixed column as the center of the array, guiding the movement of the clamping blocks from multiple directions, ensuring that the polarizer is always in a balanced state when clamped, and will not shift or tilt due to uneven force in a certain direction, which is crucial to ensuring the position accuracy of the polarizer in subsequent processing.

[0009] Preferably, the clamping blocks are provided in a plurality of groups, and the plurality of groups of clamping blocks are arranged in a circular array with equal spacing around the center of the circular cross section of the fixing column as the center of the array.

[0010] Preferably, two groups of the electric telescopic rods are provided, and the two groups of the electric telescopic rods are mirrored at the left and right ends of the fixed rod with the vertical midline of the front-to-back direction of the fixed rod as the mirror axis. Through this mirror-symmetrical setting, it is ensured that the clamping block can accurately move along a predetermined trajectory to achieve precise clamping of the polarizer.

[0011] Preferably, two groups of support rods and fixing rods are provided, and the two groups of support rods and fixing rods are mirror-imaged on the clamping block with the vertical midline of the front-to-back direction of the clamping base plate as the mirror axis.

This measurement method in which multiple components work together effectively improves the accuracy and reliability of the measurement.

[0013] Preferably, the telescopic block and the hollow block are arranged in the middle of the clamping base plate. Arranging the telescopic block and the hollow block in the middle of the clamping base plate is conducive to ensuring the accuracy and stability of the measurement. During the measurement process, the polarizer is placed on the clamping base plate. If the telescopic block and the hollow block deviate from the center position, it may cause uneven force during measurement, thereby affecting the accuracy of the measurement result. The design of being located in the middle can enable the hollow block to evenly sense the thickness change of the polarizer from the center position when it contacts the polarizer, thereby avoiding measurement errors caused by position deviations.

[0014] Preferably, a dustproof component is provided on the outer side of the scale groove, a dustproof plate is provided on the outer side of the scale groove, the dustproof plate is fixedly connected to the telescopic block, a baffle is fixedly connected inside the dustproof plate, a spring groove is opened on the sliding block, a small spring is fixedly connected inside the spring groove, and a round ball is fixedly connected to the small spring.
