Silicon-based OLED photoelectric performance test tool

Abstract

This utility model relates to the field of testing fixture technology, specifically a silicon-based OLED photoelectric performance testing fixture, including a shell, multiple first-type clamps and multiple second-type clamps. The multiple first-type clamps and multiple second-type clamps slide inside the shell. The shell is provided with locking components for pushing the first-type clamps and second-type clamps to move. The locking components include multiple evenly distributed locking plates that slide on the upper and lower sides inside the shell. In this silicon-based OLED photoelectric performance testing fixture, when the drive plate rotates, its upper arc-shaped drive groove pushes the push rod to move, thereby driving the spring telescopic rod and the locking plates to move closer to the center of the shell. When the first-type clamp is squeezed, the spring telescopic rod can retract to buffer and achieve pre-clamping and adaptation to testing devices and samples of different sizes. After all the second-type clamps are in close contact with the target, the rotation of the drive component stops, thereby realizing the rapid installation and disassembly of the device and sample.

Description

Technical Field

[0001] This utility model relates to the field of testing fixture technology, specifically a silicon-based OLED photoelectric performance testing fixture. Background Technology

[0002] The silicon-based OLED (organic light-emitting diode) optoelectronic performance testing fixture is a specialized testing device designed specifically for silicon-based OLED devices to accurately detect their optoelectronic characteristics. It can simulate the working environment of silicon-based OLEDs and quantify their key optoelectronic performance parameters through standardized testing procedures, providing data support for device research and development, production quality inspection, and reliability assessment.

[0003] The silicon-based OLED optoelectronic performance testing fixture uses a customized mechanical structure to stably fix the silicon-based OLED chip, ensuring accurate device positioning and good contact during testing. It integrates optical detection equipment and electrical measurement instruments to collect real-time data on the luminescence and electrical performance of the silicon-based OLED under different driving conditions.

[0004] Existing testing fixtures are installed by rotating two sets of mutually perpendicular knobs on the upper and lower sides of the interior, which drive the internal sliders to slide. The sliding of the sliders compresses the object at the center to complete the installation of the device and the sample. Because the two vertically positioned sliders compress the object, the device and the sample are displaced in the direction of pressure during installation, causing the sample to be out of the center of the testing equipment during testing, resulting in errors in the test results. Furthermore, the repeated turning of the knobs increases the complexity of the installation operation and reduces the efficiency of installation and disassembly. To address these issues, we propose a silicon-based OLED optoelectronic performance testing fixture. Utility Model Content

[0005] One of the technical problems this application aims to solve is that the device and sample installation are offset by the squeezing of two vertical sliders, which causes the sample to be out of the center of the detection equipment during detection, resulting in errors in the detection results. In addition, the repeated twisting of the knob increases the complexity of the installation operation and reduces the efficiency of installation and disassembly.

[0006] To address the aforementioned technical problems, this application provides a silicon-based OLED optoelectronic performance testing fixture, comprising a housing, multiple first-position locking blocks and multiple second-position locking blocks, wherein the multiple first-position locking blocks and multiple second-position locking blocks slide inside the housing, and the housing is provided with a locking element for pushing the first-position locking blocks and second-position locking blocks to move.

[0007] Preferably, the locking component includes multiple evenly distributed locking plates that slide on the upper and lower sides inside the housing. A spring telescopic rod is provided in the middle of the locking plate. The locking block is provided at the front end of the spring telescopic rod. A push rod is provided at the rear end of the spring telescopic rod. A drive plate is rotatably connected to both the upper and lower sides inside the housing. The push rod slides on the upper part of the drive plate.

[0008] Preferably, the upper part of the drive plate is provided with a plurality of evenly distributed drive grooves, the drive grooves are arc-shaped, the lower end of the push rod slides inside the drive groove, the upper part of both the left and right ends of the locking plate is provided with guide blocks, and the inside of the outer shell is provided with a drive component for driving the drive plate to rotate.

[0009] Preferably, the driving component includes two worm gears, two worms, and two gears rotatably connected to the upper and lower sides inside the housing. Two driving rings are rotatably connected to the middle of the housing. A toothed groove is provided on the side of the driving plate near the worm gears. The worm gears and the toothed grooves mesh with each other. A toothed groove is provided on the inner wall of the driving rings. The gears mesh inside the toothed grooves.

[0010] Preferably, the worm is disposed at the lower part of the gear, and the worm wheel and the worm mesh with each other.

[0011] Preferably, the front of the first card block is provided with an anti-slip pad, and telescopic plates are provided on both the left and right sides of the anti-slip pad.

[0012] Preferably, the end of the telescopic plate away from the anti-slip pad is located on the rear side of the locking plate, and the middle part of the telescopic plate abuts against the left and right ends of the locking plate.

[0013] This utility model has at least the following beneficial effects:

[0014] 1. When the drive plate rotates, the arc-shaped drive groove on its upper part pushes the push rod to move, which in turn drives the spring telescopic rod and the locking plate to move closer to the center of the outer shell. When the first clamp is squeezed, the spring telescopic rod can retract to buffer and achieve pre-clamping and adapt to detection devices and samples of different sizes. After all the second clamps are in close contact with the target, the drive component stops rotating, thereby realizing the center positioning, quick installation and disassembly of the device and sample.

[0015] 2. Rotating the drive ring causes the second tooth groove on its inner wall to drive the gear to rotate. The gear is coaxially connected with the worm, thereby driving the worm to rotate. The worm drives the worm wheel to rotate. At the same time, the self-locking characteristics of the worm and worm wheel are used to prevent the worm wheel from reversing. The worm wheel drives the drive plate to rotate inside the housing, providing power for the clamping action and ensuring stable transmission. Attached Figure Description

[0022] 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.

[0023] Example 1: Please refer to Figure 1-4 This utility model provides a technical solution: a silicon-based OLED photoelectric performance testing fixture, including a shell 1, multiple first-type 11 and multiple second-type 12, the multiple first-type 11 and multiple second-type 12 sliding inside the shell 1, and a locking member 2 for pushing the first-type 11 and the second-type 12 to move is provided inside the shell 1.

[0024] The outer shell 1 serves as a connection between the detection device and the sample. After inserting the outer shell 1 into the lower part of the detection device and the sample into the lower part of the outer shell 1, the rotating drive component 3 drives the locking component 2 to move and push the locking blocks 11 and 22 to lock the outer shell 1 and the detection device, and the outer shell 1 and the sample, thus completing the installation of the outer shell 1 and the sample. The locking blocks 11 and 22 are arc-shaped to increase the contact area of ​​the locking blocks 11 and 22.

[0025] Furthermore, the locking component 2 includes multiple evenly distributed locking plates 21 that slide inside the upper and lower sides of the housing 1. A spring telescopic rod 22 is provided in the middle of the locking plate 21. A locking block 11 is provided at the front end of the spring telescopic rod 22. A push rod 23 is provided at the rear end of the spring telescopic rod 22. A drive plate 24 is rotatably connected to both the upper and lower sides of the housing 1. The push rod 23 slides on the upper part of the drive plate 24.

[0026] Furthermore, the upper part of the drive plate 24 is provided with a plurality of evenly distributed drive grooves 25. The drive grooves 25 are arc-shaped. The lower end of the push rod 23 slides inside the drive groove 25. The upper part of both the left and right ends of the locking plate 21 is provided with guide blocks 26. The inside of the outer shell 1 is provided with a drive component 3 for driving the drive plate 24 to rotate.

[0027] Rotating the drive plate 24 can cause the drive groove 25 to push the push rod 23, which in turn drives the spring telescopic rod 22 and the locking plate 21 to move towards the center of the outer shell 1. The guide block 26 can stabilize the sliding at the edge of the locking plate 21. When the first locking block 11 is squeezed, the spring telescopic rod 22 can stop moving by retracting. The locking plate 21 continues to move towards the center of the outer shell 1. When the second locking block 12 squeezes the object at the center, the drive plate 24 stops rotating, causing the locking plate 21 to stop rotating. This allows the installation of the outer shell 1 and the sample.

[0028] Furthermore, the drive component 3 includes two worm gears 32, two worms 33, and two gears 34 rotatably connected to the upper and lower sides inside the housing 1. Two drive rings 31 are rotatably connected to the middle of the housing 1. The drive plate 24 has a tooth groove 35 on the side near the worm gears 32. The worm gears 32 and the tooth groove 35 mesh with each other. The inner wall of the drive ring 31 has a tooth groove 36, and the gears 34 mesh inside the tooth groove 36.

[0029] Furthermore, the worm 33 is located at the lower part of the gear 34, and the worm wheel 32 and the worm 33 mesh with each other.

[0030] Rotating the drive ring 31 causes the toothed groove 36 to drive the gear 34 and the worm 33 to rotate. After the worm 33 rotates, it can drive the worm wheel 32 to rotate. The cooperation between the worm 33 and the worm wheel 32 can prevent the worm wheel 32 from reversing. The rotation of the worm wheel 32 can drive the drive plate 24 to rotate through the transmission of the toothed groove 35. By rotating the two drive rings 31 on the upper and lower sides, the locking parts 2 on the upper and lower sides can be driven, thereby realizing the quick installation and disassembly of the outer shell 1 and the sample.

[0031] Example 2: Please refer to Figure 5 Based on Embodiment 1, this utility model provides another technical solution: the front of the card block 11 is provided with an anti-slip pad 111, and telescopic plates 112 are provided on both the left and right sides of the anti-slip pad 111.

[0032] Furthermore, the end of the telescopic plate 112 away from the anti-slip pad 111 is located on the rear side of the locking plate 21, and the middle part of the telescopic plate 112 abuts against the left and right ends of the locking plate 21.

[0033] The anti-slip pad 111 and the telescopic plate 112 are made of elastic material. The telescopic plate 112 can extend and retract. When the locking block 11 contacts the detection device and the sample, the spring telescopic rod 22 retracts, reducing the distance between the locking block 11 and the locking plate 21. The telescopic plate 112 is slightly stretched. The telescopic plate 112 can deform and fit against the outer wall of the detection device and the sample, thereby increasing the friction between the anti-slip pad 111 and the telescopic plate 112. The area of ​​the detection device and the sample under pressure is increased, which can make the pressure between the two more balanced and effectively prevent wear on the pressure surface of the detection device and the sample.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
