Description

Technical Field

[0001] This utility model relates to the field of polarizer detection technology, specifically to a polarizer detection device that facilitates data recording. Background Technology

[0002] Polarizing films are crucial optical materials in fields such as liquid crystal displays, optical components, and biosensors. Their polarization properties directly impact the overall optical quality and performance stability of the system. Therefore, polarizing characteristic testing is often required before polarizing films leave the factory or during use, including measurements of parameters such as polarization direction, transmittance, birefringence, and defect distribution. Common testing methods primarily rely on tools such as polarizing microscopes, polarizing interferometers, or automatic image acquisition devices to image and analyze the sample's response at different polarization angles, thereby determining whether the polarizing film meets quality standards.

[0003] Currently, after most polarizer tests are completed, the results are still recorded manually. Operators manually fill in information such as image number, angle, and test results in paper forms or notebooks. However, because polarizers have highly uniform appearances, and because samples and recorded information are separated after batch testing, misalignment or information confusion is easily caused during handling, storage, or archiving. This results in test data not accurately corresponding to specific samples, affecting the traceability of testing and the accuracy of product quality control. Furthermore, manual recording is inefficient, susceptible to human error, and cannot meet the needs of modern, standardized testing. Utility Model Content

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] Furthermore, the term "and / or" in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0029] like Figures 1 to 5 As shown, this embodiment provides a polarizing light detection device for convenient data recording, including a detection stage 1 and a polarizing fixture 2. The detection stage 1 is a structural platform with a flat working surface, used to support the light source components required during the detection process and the placement of the polarizing fixture 2. The detection stage 1 is provided with a light source 11 for providing the detection light source. The light source 11 is located at one end or the center of the detection stage 1, and is used to emit illumination light with stable brightness and directionality, thereby meeting the visual detection requirements of the polarizing film.

[0030] The polarizer fixture 2 is an easy-to-operate auxiliary clamping structure for testing, enabling the fixing, marking, and handling of the polarizer. Specifically, the polarizer fixture 2 includes a polarizer receiving groove 21, which is an upward-opening groove structure with an open bottom to allow the test light to pass through the polarizer from the bottom. A limiting edge 22 is provided within the polarizer receiving groove 21 to limit the placement position of the polarizer within the groove, ensuring stable positioning of the polarizer during testing and preventing displacement or tilting from interfering with the test results.

[0031] Furthermore, the limiting edge 22 is set along the bottom edge of the polarizer receiving groove 21 to form a partial enclosure of the edge of the polarizer, thereby realizing the physical limiting function and ensuring that the polarizer is always in the specified position during repeated movement or rotation, which is beneficial to improving detection consistency and repeatability.

[0032] To improve the convenience and practicality of data recording, the polarizer fixture 2 is equipped with a writing area 23. The writing area 23 is located on the outer surface of the fixture in a position suitable for manual writing. It is a rectangular or other geometrically shaped marking area, and the surface is made of erasable whiteboard material. The operator can use a whiteboard marker to directly write test results, numbers, defect descriptions, or other information related to the polarizer in this area. This structural design achieves physical binding between the test data and the polarizer under test, fundamentally avoiding the confusion or misjudgment caused by data detachment from the sample.

[0033] During use, the operator inserts the polarizer to be tested into the polarizer receiving slot 21 of the polarizer fixture 2 according to its size specifications. The polarizer is accurately positioned at the bottom of the receiving slot by the limiting edge 22. Subsequently, the polarizer fixture 2 containing the polarizer is placed in the predetermined position on the testing table 1, with the polarizer facing the light source 11 set on the testing table 1. The light emitted by the light source 11 passes through the open bottom of the polarizer receiving slot 21 and illuminates the surface of the polarizer, allowing the operator to observe the optical characteristics of the polarizer, such as brightness uniformity, visible defects, and polarization uniformity.

[0034] After completing one inspection of the polarizer, the operator can immediately write and mark the results in the writing area 23 of the polarizer fixture 2, such as "pass," "bubble defect," or other judgment information. Since the writing area 23 is directly set on the fixture structure that holds the polarizer, the recorded information always moves together with the polarizer being inspected, thus effectively avoiding information misalignment during subsequent transfer, placement, or centralized re-inspection.

[0035] The polarizer that has been tested, along with its polarizer fixture 2, can be moved as a whole to the other side of the testing station 1 or to a temporary storage area. When further processing or verification is needed, the operator only needs to put the fixture back into the irradiation area of ​​the light source 11 to carry out the subsequent testing or confirmation process. The whole operation process is seamless and efficient.

[0036] In this embodiment, the testing platform 1 is provided with two support legs 3, which are located on the bottom sides of the testing platform 1, respectively, to provide a stable support foundation for the entire device. The top of each support leg 3 is provided with a mounting plate 4, which is a horizontally arranged rigid structural plate, serving as a mounting base platform for the motion mechanism. This platform can bear the installation and operating loads of the upper moving parts, ensuring a compact and stable device structure.

[0037] A linear drive mechanism 5 is mounted on the mounting plate 4. The linear drive mechanism 5 is used to realize the precise reciprocating movement of the pick-and-place component 6 in one direction, thereby completing the automatic transfer operation of the polarizer fixture 2. The linear drive mechanism 5 includes two guide rails 51, a lead screw 52, ​​a slider 53, a motor 54, and a moving plate 55. The two guide rails 51 are mounted on the lower surface of the mounting plate 4 with parallel spacing to form a double-rail guiding structure, which improves the guiding accuracy and load-bearing capacity of the running components. The slider 53 is slidably connected to the two guide rails 51 respectively, and can slide smoothly on the guide rails 51.

[0038] The lead screw 52 is arranged along the direction of the guide rail 51 and is rotatably connected to the mounting plate 4 via a bearing structure. One end of the lead screw 52 is connected to the output shaft of the motor 54 via a coupling or other connection method. The motor 54 is a drive actuator used to provide torque to the lead screw 52. When the motor 54 starts, its output end drives the lead screw 52 to rotate, thereby causing the movable plate 55, which is threaded onto the lead screw 52, ​​to move linearly along the axial direction.

[0039] The upper part of the movable plate 55 is fixedly connected to the slider 53 to ensure that its linear sliding on the guide rail 51 is controlled and stable. At the same time, the movable plate 55 is connected to the lead screw 52 through a threaded structure to realize the conversion relationship between power transmission and linear feed. Through the cooperation of the guide rail 51 and the slider 53, the swaying or shaking of the movable plate 55 during operation is effectively prevented, thereby improving its overall running stability and repeatability.

[0040] Furthermore, a pick-and-place assembly 6 is connected to the lower surface of the moving plate 55. The pick-and-place assembly 6 is used to complete the adsorption, movement, and release process of the polarizer fixture 2. Specifically, the pick-and-place assembly 6 includes two electric push rods 61 and a suction cup assembly 62. Both electric push rods 61 are vertically mounted on the lower surface of the moving plate 55 with their output ends facing downwards, and are used to drive the suction cup assembly 62 to move in the vertical direction. The suction cup assembly 62 is connected between the output ends of the two electric push rods 61 through a structural bracket, and its adsorption surface is set downwards to facilitate contact and adsorption with the upper surface of the polarizer fixture 2.

[0041] During use, firstly, the two electric push rods 61 extend synchronously, causing the suction cup assembly 62 to move downwards vertically until it contacts the upper surface of the polarizer fixture 2 to be moved. Once in contact, the suction cup assembly 62 activates its adsorption function using pneumatic or negative pressure principles, firmly adhering the polarizer fixture 2 to the suction cup surface. Then, the electric push rods 61 retract, raising the suction cup assembly 62 and the polarizer fixture 2 together to a predetermined height. Next, the motor 54 drives the lead screw 52 to rotate, causing the moving plate 55 to move along the guide rail, thereby driving the entire pick-and-place assembly 6 and the adsorbed polarizer fixture 2 to achieve spatial transfer.

[0042] Once the polarizer fixture 2 has moved to the designated placement position (e.g., a temporary storage area or a stacking area), the electric push rod 61 is first extended again, causing the suction cup assembly 62 to slowly lower the polarizer fixture 2 onto the target platform. Then, the suction cup is released, completing the release action. By repeating the above steps, continuous picking, placing, and handling of multiple polarizer fixtures 2 can be achieved.

[0043] In this embodiment, the suction cup assembly 62 further includes a connector 621 and a suction cup 622. The suction cup 622 is a negative pressure adsorption structure made of flexible material. Its upper part is connected to the output end of the electric push rod 61 through the connector 621, which is used to realize the overall installation and position adjustment functions of the suction cup assembly 62.

[0044] Specifically, the connector 621 is horizontally positioned and has an internal strip-shaped notch 623 extending in one direction. The notch 623 is a long, narrow groove structure with guiding and adjustment functions. The upper end of the suction cup 622 passes through the strip-shaped notch 623 and is slidably connected to it, allowing for fine-tuning of the suction cup 622's position within the direction defined by the connector 621. Two nuts 624 are threadedly connected to the insertion portion of the suction cup 622, located on the upper and lower surfaces of the connector 621 respectively, thus forming a clamping and fixing structure.

[0045] In practical use, the operator can first loosen the two nuts 624, allowing the suction cup 622 to slide relative to the strip notch 623. Then, the operator can manually push the suction cup 622 to slide along the designated direction within the strip notch of the connector 621, thereby adjusting the horizontal position of the suction cup 622. After the suction cup 622 is aligned with the suction part 24 on the polarizer fixture 2, the nuts 624 are tightened to securely lock the suction cup 622 onto the connector 621, preventing displacement or detachment during subsequent handling and ensuring the stability and safety of the pick-and-place operation. This structural design enhances the adaptability of the suction cup assembly, allowing for flexible adjustment of the suction position and improving compatibility with polarizer fixtures of different sizes or structures.

[0046] Furthermore, to improve the overall structural load-bearing capacity and operational stability, a reinforcing rib 7 is provided between the support leg 3 and the mounting plate 4. The reinforcing rib 7 is a reinforcing structural component connecting the support leg 3 and the mounting plate 4, which can provide additional support stiffness to the mounting plate 4, effectively suppressing vibration and swaying caused by inertial load or driving stress during the movement of the linear drive mechanism 5, and ensuring the overall operational stability of the device and the structural reliability for long-term use.

[0047] Furthermore, in this embodiment, to further improve the reliability of adsorption during handling and the safety of stacking operations, suction portions 24 matching the suction cup assembly 62 are provided on both sides of the polarizer fixture 2. The suction portion 24 may be a partially protruding structure, with its height higher than the main body plate surface of the polarizer fixture 2, forming a dedicated area for positioning and adsorption by the suction cup 622.

[0048] By designing the suction part 24 as a protruding portion higher than the tooling plate surface, a small gap is formed between the tooling plates when multiple polarizer tooling 2s are stacked vertically, effectively avoiding the risk of pressure damage to the polarizers caused by direct contact. Simultaneously, this structure facilitates accurate contact between the suction cup assembly 62 and the suction part 24 during handling, improving the precision and efficiency of the suction operation. Due to the reasonable height setting of the suction part 24, both ease of handling and polarizer safety are considered without affecting the stable placement of the tooling, contributing to improving the automation and standardization level of the overall polarizer inspection process.

[0049] The specific embodiments described above do not constitute a limitation on the scope of protection of this utility model. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
