Description

Technical Field

[0001] The utility model belongs to the technical field of detection equipment, and in particular relates to a detection fixture for a core component of a light-emitting unit. Background Art

[0002] Light-emitting unit core component testing equipment, as an important tool in modern science and technology, is widely used in multiple fields such as display technology, biomedicine, and materials science. Light-emitting unit core component testing equipment is mainly used to test the performance and quality of light-emitting elements, including key parameters such as luminous intensity, wavelength, and spectral characteristics. These devices are based on different detection principles and technologies to achieve accurate measurement and analysis of the core components of light-emitting units. Publication No.: CN112665824A provides a micro-LED testing device, which relates to the field of optical detection technology and is used to solve the problem of inaccurate yield detection results of micro-LEDs. The micro-LED testing device includes an image acquisition unit, a sample detection platform, a spectrometer, an excitation light source, and an imaging light source. The image acquisition unit is arranged above the sample detection platform, and the spectrometer is located between the image acquisition unit and the sample detection platform. The light emitted by the imaging light source is refracted by the spectrometer and illuminates the micro-LED on the sample detection platform. The light emitted by the excitation light source is reflected by the spectrometer and illuminates the micro-LED. The image acquisition unit is used to capture images of the metal electrode layer and insulating layer of the micro-LED, as well as the epitaxial layer of the micro-LED. The yield rate of micro light-emitting diodes tested by the micro light-emitting diode detection equipment provided by the present invention is more accurate.

[0003] However, there are some problems with the existing technology: the existing light-emitting unit core component detection equipment cannot quickly fix the core component in the center when fixing the core component, and multiple adjustments are required. The fixing process is relatively cumbersome, and when the core component needs to be powered on, the connection lines are placed in a messy manner, and it is not easy to store after the inspection is completed. Therefore, we propose a light-emitting unit core component detection fixture. Utility Model Content

[0027] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0028] like Figures 1 to 7 As shown, an embodiment of the present invention provides a light-emitting unit core component detection fixture, including a detection box 1. The detection box 1 is rectangular and made of stainless steel. The main function of the detection box 1 is to protect the components therein and provide a detection space.

[0029] The inner wall of the testing box 1 is fixedly connected to a testing platform 2, and a turntable 3 is rotatably connected to the testing platform 2. A groove is provided at the upper end of the testing platform 2, and a rotating shaft 11 is rotatably connected in the groove. One end of the rotating shaft 11 is fixedly connected to the bottom end of the turntable 3, and a handle 16 is fixedly connected to the outer wall of the turntable 3. The handle 16 is used to drive the turntable 3 to rotate.

[0030] A threaded hole is provided on one side of the testing table 2, and a locking screw 17 is threadedly connected to the threaded hole. The locking screw 17 is used to limit the rotation of the rotating shaft 11. After loosening the locking screw 17, the turntable 3 can rotate on the testing table 2. When the locking screw 17 is tightened, the turntable 3 cannot rotate.

[0031] The turntable 3 is movably connected to the fixed block 4, and the fixed block 4 is provided with four groups. The four groups of fixed blocks 4 are evenly distributed on the turntable 3 in a circle. Of course, the number of fixed blocks 4 is not limited to four sides, and can also be set to three groups, five groups, etc. A slide is provided at the upper end of the testing platform 2, and a slider 12 is slidably connected in the slide. The upper end of the slider 12 is fixedly connected to a connecting rod 13, and a guide hole is provided on the turntable 3. The connecting rod 13 is arranged through the guide hole, and the connecting rod 13 is fixedly connected to the lower end of the fixed block 4.

[0032] After rotating the turntable 3 with the handle 16, the guide hole on the turntable 3 also rotates accordingly, so that the connecting rod 13 slides along the slide on the test platform 2 under the pressure of the guide hole, and then the fixed block 4 on the connecting rod 13 moves toward the center of the test platform 2, thereby fixing the luminous core assembly at the center of the test platform 2.

[0033] The fixed block 4 is movably connected to the card block 5, the number of the card blocks 5 corresponds to the fixed block 4, a receiving groove is opened at one end of the fixed block 4, a spring 14 is fixedly connected to the inner wall of the receiving groove, the spring 14 is fixedly connected to the adjusting rod 15, and the adjusting rod 15 is fixedly connected to the card block 5.

[0034] When the card block 5 moves toward the center of the detection table 2 along with the fixed block 4 and contacts the luminous core component, the spring 14 will be compressed and move toward the storage groove, so that multiple groups of card blocks 5 can be tightly attached to the luminous core component and fix it, so that the utility model can fix luminous core components of different shapes.

[0035] Both ends of the detection platform 2 are fixedly connected to a wire-taking platform 6, a cavity is opened in the wire-taking platform 6, and a wire-taking assembly 7 is movably connected in the cavity. The wire-taking assembly 7 includes a connecting shaft 701, and the connecting shaft 701 is fixedly connected to the inner wall of the cavity of the wire-taking platform 6. A wire-taking wheel 702 is rotatably connected to the connecting shaft 701, and two groups of limiting rings 703 are fixedly connected to the connecting shaft 701. The wire-taking wheel 702 is arranged between the two groups of limiting rings 703.

[0036] A circular groove is opened in the middle of the take-up wheel 702, and an elastic steel coil 704 is wound on the connecting shaft 701. One end of the elastic steel coil 704 is fixedly connected to the connecting shaft 701, and the other end of the elastic steel coil 704 is fixedly connected to the inner wall of the circular groove.

[0037] An electric wire 705 is wound around the take-up wheel 702 , and a avoidance hole is provided on one side of the take-up platform 6 . The electric wire 705 passes through the avoidance hole, and one end of the electric wire 705 is fixedly connected to the electrode clamp 706 .

[0038] Pull the electrode clamp 706 outward, and the electrode clamp 706 will drive the wire 705 to move outward, thereby driving the take-up wheel 702 to overcome the elastic rotation of the elastic steel coil 704. When the electrode clamp 706 is released, the take-up wheel 702 will rotate due to the rebound force of the elastic steel coil 704, thereby automatically storing the wire 705.

[0039] A detection probe 8 is fixedly connected to the inner wall of the detection box 1. The detection probe 8 is usually composed of a photoelectric converter and an amplifier, and can convert weak optical signals into stronger electrical signals for measurement and analysis.

[0040] The front side of the detection box 1 is rotatably connected to a box door 9 , one side of the detection box 1 is fixedly connected to a hinge 18 , the hinge 18 is fixedly connected to the box door 9 , and one side of the box door 9 is fixedly connected to a handle 19 .

An adjustable DC power supply and a control unit are provided in the console 10. The adjustable DC power supply is used to adjust the voltage and current of the power supply output. The control unit is controlled by a microprocessor or a digital signal processor to realize automated testing and data acquisition.

[0042] The working principle of this utility model is as follows:

[0043] The utility model can drive the turntable 3 to rotate by rotating the handle 16. When the turntable 3 rotates, the guide hole on the turntable 3 will cause the connecting rod 13 to slide along the slide groove on the detection platform 2 toward the midpoint of the turntable 3, thereby driving the fixed block 4 and the card block 5 to move toward the midpoint of the turntable 3, thereby fixing the light-emitting core component at the center of the detection platform 2, and making the data collected by the detection probe 8 more accurate.

[0044] The clamping block 5 of the present invention is movably connected to the fixing block 4 through the adjusting rod 15 and the spring 14, so that the clamping block 5 can be contracted according to the shape of the light-emitting core component, so that the present device can fix light-emitting core components of different shapes. At the same time, the turntable 3 drives the clamping block 5 to contract and expand, so that the present invention can also fix light-emitting core components of different sizes.

[0045] The present invention is provided with a wire-reeling assembly 7, which can pull out the wire 705 by pulling the electrode clamp 706 outward, and clamp the electrode clamp 706 on the light-emitting core assembly after it reaches a sufficient length. After the detection is completed, after loosening the electrode clamp 706, the wire-reeling wheel 702 will rotate due to the elasticity of the elastic steel coil 704, so that the wire-reeling wheel 702 automatically retracts the wire 705, avoiding the wire 705 being messy and difficult to retract.

[0046] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
