Description

Technical Field

[0001] This utility model relates to the field of measurement and calculation technology, and in particular to a polarizer thickness measurement platform. Background Technology

[0002] A polarizer, also known as a light polarizer, is an optical thin film with selective light transmission capability. It can convert natural light into linearly polarized light that vibrates in a specific direction, filtering out the polarized light. A thickness measurement platform is a specialized equipment system used to accurately measure the thickness of various materials and objects. It is widely used in manufacturing, quality inspection, scientific research and other fields. Its core function is to obtain the thickness data of the target object through specific detection technology to meet the needs of production process control, product quality acceptance and experimental analysis.

[0003] A polarizer thickness measurement platform typically consists of a feeding and positioning module, a measurement core module, a transmission and conveying module, and a data processing and control module. Their workflows are closely integrated. The feeding and positioning module precisely fixes the polarizer and delivers it to the measurement area through vacuum adsorption and mechanical limiting structures, ensuring a unified measurement benchmark. The measurement core module mostly uses laser displacement sensors and capacitive sensors. The sensors, arranged symmetrically, simultaneously collect the position signals of the upper and lower surfaces of the polarizer, and the thickness data is obtained by calculating the difference.

[0004] In existing technologies, the measuring heads in some measurement platforms are mostly fixedly installed, making it difficult to make flexible adjustments in multiple directions according to different specifications of polarizers and measurement requirements. This makes it difficult for the measuring head to be accurately aligned with the area to be measured, especially for non-planar and irregularly shaped polarizers, which easily leads to measurement blind spots. This not only prolongs the measurement preparation time but also reduces the detection efficiency. Therefore, in order to address the above shortcomings, a polarizer thickness measurement platform is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a polarizer thickness measurement platform, which aims to improve the problem that some existing thickness measurement platforms are difficult to adjust and measure from multiple directions.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A polarizer thickness measurement platform includes a support platform, an adjustment mechanism is slidably connected inside the support platform, and a fixing mechanism is fixedly connected to the top of the support platform; The adjustment mechanism includes a U-shaped sliding plate, the outside of which is slidably connected to the inside of the support platform. Multiple teeth are fixedly connected to the left side of the inside of the U-shaped sliding plate. A drive assembly is fixedly connected to the bottom of the support platform. A fixed cavity is fixedly connected to the top of the U-shaped sliding plate. Bolts are threadedly connected to both sides of the fixed cavity. A sliding connecting plate is slidably connected to the inside of the fixed cavity. As a further description of the above technical solution: The drive assembly includes a motor, the top of which is fixedly connected to the bottom of the support platform, a rotating shaft is fixedly connected to the drive end of the motor, and a gear is fixedly connected to the outside of the rotating shaft. As a further description of the above technical solution: The fixing mechanism includes a placement platform, the bottom of which is fixedly connected to the top of the support platform, and an air pump is fixedly connected inside the placement platform. As a further description of the above technical solution: The output end of the air pump is fixedly connected to a transport pipe, and the other end of the transport pipe is fixedly connected to a transmission channel. As a further description of the above technical solution: The transmission channel has air vents on both the left and right sides inside, and a ceramic disc is fixedly connected to the top of the transmission channel. As a further description of the above technical solution: The outer surface of the gear is meshed with the outer surface of the plurality of teeth, and the outer surface of the plurality of teeth is slidably connected to the interior of the support platform; As a further description of the above technical solution: The gear is externally rotatably connected to the inside of the support platform, and the support platform is internally rotatably connected to the outside of the rotating shaft; As a further description of the above technical solution: The left and right sides of the sliding connecting plate are threaded to the adjacent side of the two bolts, and a measuring head is fixedly connected to the outside of the sliding connecting plate.

[0007] This utility model has the following beneficial effects: 1. In this utility model, the rotating shaft is driven by the starting motor to rotate, which in turn drives the gear to rotate. Because the gear and teeth mesh with each other, the teeth convert the rotational force into thrust, which drives the measuring head to move. Then, the sliding connecting plate slides up and down inside the fixed cavity to adjust the height of the measuring head, thus realizing the function of multi-directional position adjustment, which makes the measurement more convenient and accurate.

[0008] 2. In this utility model, gas is generated by starting the air pump and transported through the transport pipe to the transfer channel. Then, it is transported through the channel in the transfer channel to the two air outlet holes, generating a large pressure that adsorbs and fixes the polarizer placed on the ceramic disc, achieving a non-damaging fixation effect.

Detailed Implementation

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] A polarizer thickness measurement platform, referring to Figure 1 , Figure 3 and Figure 4 The system includes a support platform 1, which serves as the basic load-bearing structure for the entire polarizer thickness measurement platform. An adjustment mechanism 2 is slidably connected inside the support platform 1. The adjustment mechanism 2 includes a U-shaped sliding plate 21, which provides a fixed installation position for the teeth 22. The U-shaped sliding plate 21 is slidably connected to the outside of the support platform 1. Multiple teeth 22 are fixedly connected to the left side of the inside of the U-shaped sliding plate 21, which converts the rotational power output by the drive component 23 into the linear motion power of the U-shaped sliding plate 21. Specifically, the support platform 1 serves as the basic load-bearing structure, providing stable support for the overall device and ensuring structural stability during the measurement process. It is the foundation for accurate measurement. The adjustment mechanism 2 achieves flexible displacement through the sliding connection between the U-shaped sliding plate and the support platform 1. The multiple teeth 22 on the left side of the mechanism can efficiently convert the rotational power of the drive component 23 into linear motion power, allowing the U-shaped sliding plate to be adjusted as needed.

[0013] A drive assembly 23 is fixedly connected to the bottom of the support platform 1. The drive assembly 23 includes a motor 231, which provides rotational power for the rotation of the rotating shaft 232 and the gear 233. The top of the motor 231 is fixedly connected to the bottom of the support platform 1. The drive end of the motor 231 is fixedly connected to the rotating shaft 232, which is responsible for transmitting the rotational power output by the motor 231 to the gear 233. The gear 233 is fixedly connected to the outside of the rotating shaft 232. Through meshing with the teeth 22, the rotational power transmitted by the rotating shaft 232 is converted into a thrust that can drive the U-shaped sliding plate 21 to move linearly. The gear 233 is externally rotatably connected to the inside of the support platform 1. The internal rotating connection of the platform 1 is external to the rotating shaft 232. The top of the U-shaped sliding plate 21 is fixedly connected to the fixed cavity 24, which provides sliding space for the sliding connecting plate 26. Bolts 25 are threaded on both sides of the fixed cavity 24 to lock the sliding connecting plate 26 in the height position within the fixed cavity 24. The sliding connecting plate 26 is slidably connected inside the fixed cavity 24. The height of the measuring head 27 is adjusted by sliding the plate 26 within the fixed cavity 24. The left and right sides of the sliding connecting plate 26 are threaded to the adjacent side of the two bolts 25. The measuring head 27 is fixedly connected to the outside of the sliding connecting plate 26, which is responsible for collecting the thickness data of the polarizer. Specifically, the motor 231 transmits power stably to the gear 233 through the rotating shaft 232. The gear 233 meshes with the teeth 22 to reliably convert rotational power into linear thrust. With the limit support of the support platform 1, the displacement of the U-shaped sliding plate is stable and controllable, providing a stable horizontal adjustment base for the measuring head 27. The height adjustment structure composed of the fixed cavity 24, the sliding connecting plate 26 and the bolt 25 is flexible and practical. The sliding connecting plate 26 can slide along the fixed cavity 24 to adjust the height of the measuring head 27, and the bolt 25 can be locked to quickly fix the position, adapting to the measurement needs of polarizers of different thicknesses.

[0014] Reference Figures 1 to 3The top of the support platform 1 is fixedly connected to a fixing mechanism 3, which includes a placement platform 31. The bottom of the placement platform 31 is fixedly connected to the top of the support platform 1. An air pump 32 is fixedly connected inside the placement platform 31, which is the power source of the adsorption fixing system. The output end of the air pump 32 is fixedly connected to a transport pipe 33, which delivers the high-pressure gas generated by the air pump 32 to the transfer channel 34 without leakage. The other end of the transport pipe 33 is fixedly connected to the transfer channel 34, which receives the high-pressure gas delivered by the transport pipe 33 and distributes it evenly to the air outlet holes 35 on the left and right sides. Air outlet holes 35 are opened on both the left and right sides inside the transfer channel 34, which converts the high-pressure gas in the transfer channel 34 into an adsorption force that directly acts on the polarizer. A ceramic disc 36 is fixedly connected to the top of the transfer channel 34, providing a flat, smooth, and wear-resistant contact surface. The outside of the gear 233 is meshed with the outside of multiple teeth 22, and the outside of the multiple teeth 22 is slidably connected inside the support platform 1. Specifically, the placement stage 31 serves as the core support, and its top ceramic disc 36 has a flat, smooth, and wear-resistant surface, providing a high-quality contact surface for the polarizer. This avoids data accuracy issues caused by uneven contact surfaces during measurement. The adsorption system, consisting of the air pump 32, transport pipe 33, transfer channel 34, and air outlet 35, is highly efficient and practical. The high-pressure gas generated by the air pump 32 is transported leak-free through the transport pipe 33 to the transfer channel 34, and then converted into adsorption force by the air outlets 35 on both sides. This quickly and firmly fixes the polarizer, preventing displacement or shaking during measurement. At the same time, the adsorption fixing method reduces contact damage to the surface of the polarizer. Combined with the precise meshing of the gears 233 and teeth 22 in the adjustment mechanism 2, the measuring head 27 can be accurately aligned with the fixed polarizer, further ensuring the reliability of thickness measurement.

[0015] The implementation principle of this application embodiment is as follows: First, the polarizer to be measured is placed on the ceramic disc 36, and the air pump 32 inside the placement stage 31 is started. The generated gas is transported to the transfer channel 34 through the transport pipe 33. The gas flows inside the transfer channel 34 and enters the air outlet hole 35 respectively. Finally, it is ejected from the air outlet hole 35. The ejected gas forms a certain pressure, which generates an adsorption force on the polarizer placed on the ceramic disc 36, thereby fixing the polarizer firmly on the surface of the ceramic disc 36 and fixing the polarizer.

[0016] The starter motor 231 drives the rotating shaft 232 to rotate, which in turn drives the gear 233 to rotate. Because the gear 233 meshes with the teeth 22, the rotational force of the gear 233 is converted into a thrust on the U-shaped sliding plate 21 through the teeth 22. This causes the U-shaped sliding plate 21 to slide inside the support platform 1, thereby causing the fixed cavity 24 fixedly connected to the top of the U-shaped sliding plate 21 and the related components connected to the fixed cavity 24 to move horizontally. This adjusts the position of the measuring head 27 in the horizontal direction and pushes the sliding connecting plate 26 to slide up and down inside the fixed cavity 24. This causes the sliding connecting plate 26 to drive the measuring head 27 to move up and down synchronously until the measuring head 27 is adjusted to a suitable height. Then, the two bolts 25 are tightened to tightly connect the left and right sides of the sliding connecting plate 26 and fix it in place, thereby adjusting the position of the measuring head 27.

[0017] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
