Description

Technical Field

[0001] This utility model relates to the field of materials testing technology, and in particular to a pressure testing device for fluorescent materials. Background Technology

[0002] Fluorescent materials can emit longer wavelengths of light after absorbing light of a specific wavelength, which is called fluorescence. The luminescence process of fluorescent materials is due to the release of energy when electrons transition from an excited state back to the ground state, which is emitted in the form of light. Fluorescent materials have good flexibility and deformability, and have a wide range of applications, including display technology and biomedicine. Therefore, in order to ensure the quality of fluorescent materials, pressure testing devices are needed to test them. For example, existing technologies disclose strength testing devices for building materials. However, these devices are not suitable for testing fluorescent materials. Pressure testing of fluorescent materials is necessary to test the stability of the fluorescent material under pressure, such as the luminescence intensity, or whether irreversible damage has occurred. Utility Model Content

[0003] The purpose of this invention is to provide a pressure testing device for fluorescent materials, used to detect the stability of the luminescence performance of fluorescent materials under pressure.

[0004] To achieve the above-mentioned objectives, the fluorescent material pressure testing device of this utility model adopts the following technical solution:

[0005] A pressure testing device for fluorescent materials includes a base, a frame, and a testing platform. A turntable is located on top of the testing platform, and the turntable is equipped with a rotation mechanism for driving its rotation. Multiple fluorescent materials are arranged circumferentially on the turntable. A pressing member is located above the fluorescent materials on the frame, and the pressing member is driven to move up and down by a lifting mechanism. The turntable rotates, causing the multiple fluorescent materials to sequentially pass directly beneath the pressing member. The pressing member is used to press down on the fluorescent materials directly below it, and it is equipped with a pressure detection device to detect the downward pressure. A through-hole is provided at the position on the turntable where the fluorescent materials are arranged. An imaging device is located below the turntable on the testing platform, with its lens positioned directly beneath the pressing member pressing down on the fluorescent materials.

[0006] Preferably, the test platform is equipped with a support assembly for supporting the bottom of one side of the turntable, and the support position of the support assembly corresponds to the pressing position of the pressure member. By providing the support assembly, the turntable is supported when the pressure member presses down on the fluorescent material.

[0007] Preferably, the support assembly includes a support cylinder, the cylinder barrel of which is mounted on the test platform, and the piston rod of the support cylinder has a support block that contacts the bottom of the turntable. The support cylinder drives the piston rod to press the support block against the bottom of the turntable, thereby providing support for one side of the turntable.

[0008] Preferably, the turntable has mounting holes for mounting fluorescent materials. The mounting holes are located above the through holes and are connected. The diameter of the mounting holes is larger than the diameter of the through holes. The mounting holes facilitate the placement of the fluorescent materials within them. When the fluorescent materials are deformed under pressure and emit light, the light emitted passes through the through holes and is then collected by the imaging equipment below.

[0009] Preferably, the pressing element is a vertically arranged pressure bar, with its lower end in pressure contact with the fluorescent material. A pressure detection device, a pressure sensor, is installed at the upper end of the pressure bar. The pressure sensor is mounted on the frame via a support that can move vertically along the frame. The downward pressure exerted by the pressure bar on the fluorescent material is transmitted to the pressure sensor for collection.

[0010] Preferably, the lifting mechanism is a screw drive mechanism, comprising a first motor, a first lead screw, and a first lead screw nut. The frame is provided with a first slide rail, and the support is provided with a slide block slidably mounted on the first slide rail. The first motor is mounted on the frame, and the output shaft of the first motor is connected to the first lead screw. The slide block is provided with a first lead screw nut, and the first lead screw and the first lead screw nut are threadedly connected. The operation of the first motor drives the first lead screw to rotate, thereby realizing the lifting and lowering of the slide block along the first lead screw, further driving the pressure rod to press down on the fluorescent material directly below for testing.

[0011] Preferably, the test platform is equipped with a translation mechanism that drives it to move horizontally along the base. By setting up the translation mechanism, the placement and testing of fluorescent materials can be separated. The test platform can be moved to one side of the base to place the fluorescent material, and moved to the other side of the base for pressure testing, thereby ensuring the safety of workers and preventing them from being injured by the downward pressure bar when placing the fluorescent material.

[0012] Preferably, the translation mechanism is a screw drive mechanism, which includes a second motor, a second lead screw, and a second lead screw nut. The second motor is mounted on the base, and its output shaft drives the second lead screw. The bottom of the test platform is provided with a second lead screw nut, and the second lead screw and the second lead screw nut are threadedly connected. The base is provided with a second slide rail, and the test platform is provided with a slider that cooperates with the second slide rail. The second motor drives the second lead screw to rotate, thereby driving the second lead screw nut to translate along the second lead screw, and further driving the test platform to translate.

[0013] Preferably, the rotating mechanism includes a rotary motor mounted on the test platform, and the output shaft of the rotary motor is connected to the center of the turntable. The rotary motor drives the turntable to rotate, allowing multiple fluorescent materials arranged on the turntable to pass sequentially directly below the pressing member, thus achieving continuous detection of multiple fluorescent materials.

[0014] Preferably, the imaging device is a camera.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention arranges multiple fluorescent materials on a turntable, and the rotation of the turntable positions the fluorescent materials under a pressure element, thereby achieving continuous pressure testing of multiple fluorescent materials. Under pressure, the fluorescent materials deform and emit light. At this time, the brightness is collected by imaging equipment, and the pressure is collected by a pressure detection device to obtain test data, thereby determining whether the luminescence performance of the fluorescent materials under pressure meets the requirements. This invention has a reasonable structural design and is specifically designed for pressure testing of fluorescent materials. It can continuously test multiple fluorescent materials and is practical.

Multiple fluorescent materials 11 are arranged circumferentially on the turntable 12. A pressing member is located above the fluorescent materials 11 on the frame 6, and the pressing member is driven to rise and fall by a lifting mechanism. The turntable 12 rotates, causing the multiple fluorescent materials 11 to pass sequentially directly below the pressing member. The pressing member is used to press down on the fluorescent materials 11 directly below it, and it is equipped with a pressure detection device to detect the downward pressure. The pressing member is a vertically arranged pressure rod 4, the lower end of which is in pressure contact with the fluorescent materials 11, and the upper end of which is equipped with a pressure detection device.
