Abstract
Description
Technical Field
[0001] This utility model relates to the field of crystal annealing testing technology, specifically to a convenient and efficient annealing testing fixture. Background Technology
[0002] As a new generation of functional materials, optoelectronic functional crystals are the cornerstone of modern optoelectronic technology and are widely used in information, energy, and medical fields. These crystals achieve precise manipulation and energy conversion of light waves through special optical, electrical, or magnetic properties. For example, magneto-optical crystals utilize the ability of magnetic fields to control the polarization direction of light, becoming key components of isolators and modulators in fiber optic communication and laser systems, ensuring the stability of signal transmission; laser crystals, through the stimulated emission properties of internally doped ions, provide high-power, high-stability laser sources for industrial cutting, medical surgery, and scientific research instruments; and nonlinear optical crystals, through frequency conversion and frequency doubling effects, expand the coverage of laser wavelengths, meeting the cutting-edge needs of precision spectral analysis and quantum communication. Furthermore, with the rise of technologies such as intelligent sensing and integrated photonics, optoelectronic crystals are developing towards multifunctional composites and low-loss integration, driving continuous breakthroughs in miniaturization and high efficiency of optoelectronic devices, becoming one of the core materials supporting next-generation information technology and high-end manufacturing.
[0003] Optoelectronic functional crystals are typically oxides, halides, etc., characterized by high growth temperatures, high hardness, high brittleness, and difficulty in processing. During the high-temperature growth stage, significant internal stress is introduced due to factors such as temperature gradients, crystallization characteristics, and cooling conditions. During the processing stage, cutting, grinding, and polishing all introduce mechanical stress. The introduction of stress can lead to minute deformations in the material's crystal lattice; if used in optical devices, this can severely affect the quality of light emission and cause a decline in device performance.
[0004] Typically, the processed materials require annealing. For general optical crystal devices, the materials are brittle and hard. After processing, the annealing process requires manual handling using tweezers or hands, placing the crystal on a tray, and then removing it with tweezers or hands after annealing for testing under a stress tester. During this process, crystals are prone to falling or being bumped, causing chipping and other defects, ultimately rendering the crystal device unusable.
[0005] Therefore, existing crystal annealing detection techniques need further improvement. Utility Model Content
[0006] The purpose of this invention is to overcome the problems in existing crystal annealing testing technologies, such as the need to use tweezers or fingers to handle crystals, which involves multiple manual operations and easily leads to crystals falling, bumping, and scratching, causing edge chipping and resulting in the scrapping of crystal devices. Through the rational design of crystal annealing testing technology, using a testing tray, annealing tray, testing cavity, annealing cavity, and crystal placement area, multiple crystals can be held for annealing and testing operations. This avoids multiple manual handling of crystals, prevents crystals from falling, scratching, and bumping, and reduces the scrapping of crystal devices. It also improves testing efficiency and reduces the defect rate.
[0007] The specific technical solution of this utility model is as follows:
[0008] A convenient and efficient annealing testing fixture includes: a testing tray, an annealing tray, a testing cavity, an annealing cavity, and a crystal placement area. The testing cavity is disposed on the testing tray, the annealing cavity is disposed on the annealing tray, the testing tray covers the annealing tray, the testing cavity and the annealing cavity are interconnected and used to place and accommodate crystals, the crystal placement area is disposed on the annealing tray and located within the annealing cavity, the crystal placement area is used to place crystals, and the testing tray is a transparent testing tray.
[0009] Furthermore, the crystal placement area is located in the middle of the annealing tray.
[0010] Furthermore, there is a gap between the crystal placement area and the wall of the annealing tray.
[0011] Furthermore, the testing tray is made of transparent glass, transparent quartz, or transparent acrylic.
[0012] Furthermore, the annealing tray is made of alumina ceramic, zirconium oxide ceramic, or magnesium oxide ceramic.
[0013] Furthermore, the top of the annealing tray is provided with a locking protrusion, and the inner side of the testing tray is provided with a locking groove. The locking protrusion and the locking groove cooperate with each other and engage in a locking operation.
[0014] Furthermore, the crystal placement area is provided with a placement groove for placing crystals.
[0015] Furthermore, the placement slots are arranged in a matrix on the annealing tray.
[0016] Furthermore, the placement slot, annealing tray, and locking protrusion are integrally formed.
[0017] Furthermore, the slot and the detection tray are integrally formed.
[0018] Furthermore, a buffer pad is provided on the outside of the annealing tray, which is used to cushion the placement of the test tray and prevent the test tray from sliding on the annealing tray.
[0019] Furthermore, the cushioning pad is selected from a cushioning pad made of ceramic fiber.
[0020] Furthermore, the buffer pad is selected from a buffer pad made of aluminum silicate ceramic fiber.
[0021] Furthermore, the buffer pad is selected to be adhered to the annealing tray.
[0022] Furthermore, the buffer pad is bonded to the annealing tray using a silicate inorganic adhesive or a silicate-based adhesive.
[0023] Beneficial effects
[0024] This invention, through the rational design of crystal annealing testing technology, employs a testing tray, an annealing tray, a testing cavity, an annealing cavity, and a crystal placement area. This allows for the holding of multiple crystals for annealing and testing operations, avoiding repeated manual crystal handling, preventing crystal drops, scratches, and impacts, and reducing crystal device scrap. It also improves testing efficiency and reduces the defect rate. The use of buffer pads reduces collisions and displacement between the testing and annealing trays, minimizing wear on the crystals during movement. The placement slots separate the crystals, promoting even annealing and reducing collisions. The combination of locking protrusions and locking slots ensures the stable and effective placement of the testing tray on the annealing tray. Attached Figure Description
