Description

Technical Field

[0001] This utility model belongs to the technical field of glass fluorescent sheet testing devices, specifically a multi-angle light source adjustment frame for testing glass fluorescent sheets. Background Technology

[0002] Glass phosphors are functional optical materials that emit fluorescence when excited by a light source of a specific wavelength. They are widely used in display devices, anti-counterfeiting labels, biosensing, and optical sensing. When testing the performance of glass phosphors, it is usually necessary to illuminate them with a light source at a specific angle to observe key parameters such as fluorescence intensity, uniformity, and spectral characteristics.

[0003] Most common fluorescent sheet test light source holders rely on discrete drive structures, that is, multiple independent motors or manual components control the movement in different directions. This decentralized control mode not only leads to complex equipment structure and poor coordination, but also makes the operation process cumbersome and difficult to precisely and synchronously adjust the angle and position of multiple light sources. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-angle light source adjustment frame for testing glass fluorescent sheets, which realizes synchronous, precise and stable adjustment of multi-angle light sources.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A multi-angle light source adjustment frame for testing glass fluorescent sheets is provided, including a base. A through-slot is formed inside the base, and a dual-head motor is installed inside the through-slot. Two output ends of the dual-head motor are fixedly connected to drive shafts. A drive bevel gear is fixedly connected to the end of the drive shaft away from the dual-head motor. Support plates are fixedly connected to the front and rear of the base. Two fixed plates are fixedly connected to the top of the support plates. A driven shaft is rotatably connected between the two fixed plates. A driven bevel gear is fixedly connected to the end of the driven shaft near the drive bevel gear. A worm gear is fixedly connected to the middle section of the outer wall of the driven shaft. The drive bevel gear meshes with the driven bevel gear. A rotating shaft is rotatably connected to the outer wall of the base. A worm wheel is fixedly connected to the end of the rotating shaft away from the base. The worm gear meshes with the worm wheel. An adjustment component is fixedly connected to the outer wall of the rotating shaft.

[0006] Optionally, the adjustment assembly includes two rotating rods. The top surfaces of the two rotating rods are fixedly connected to a connecting column, and a connecting plate is fixedly connected between the two connecting columns. An electric push rod is fixedly connected to the top of the connecting plate, and the extended end of the electric push rod passes through the connecting plate and is fixedly connected to a mounting plate. A ray lamp is fixedly connected to the bottom of the mounting plate.

[0007] Optionally, two positioning plates are fixedly connected inside the through groove, and two first positioning rings are fixedly connected to the outer wall of the drive shaft, with the two first positioning rings located on both sides of the corresponding positioning plates.

[0008] Optionally, two second positioning rings are fixedly connected to the outer wall of the driven shaft, and the two second positioning rings are respectively located on both sides of the two fixed plates.

[0009] Optionally, the top of the base is provided with a groove, which is connected to a through groove. Multiple arc-shaped plates are fixedly connected to the top of the groove. The multiple arc-shaped plates are evenly distributed in a circumferential array, and a fluorescent sheet is placed in the middle of the multiple arc-shaped plates.

[0010] Optionally, the outer wall of the base is fixedly connected with a plurality of fixed feet, which are symmetrically distributed in pairs.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model uses a dual-head motor to drive the bevel gear and worm gear transmission system on both sides, synchronously transmitting a single power source to the adjustment components on both sides, so that the two ray lamps can make symmetrical and consistent circular motion around the fluorescent sheet. This centralized driving method not only simplifies the structure, but also realizes the synchronous, precise and stable adjustment of multi-angle light sources, ensuring the synchronicity and accuracy of light source angle adjustment, and overcoming the shortcomings of poor coordination and difficulty in precise positioning of traditional multi-independent drive.

[0012] 2. Based on the horizontal angle adjustment, the electric push rod integrated in the adjustment component can independently control the raising and lowering of the ray lamp, thereby realizing flexible adjustment of the irradiation height to obtain irradiation conditions under different angle and distance combinations, thus improving the coverage and efficiency of the test.

[0020] Reference Figure 1-5The present invention provides a multi-angle light source adjustment frame for testing glass fluorescent sheets. The multi-angle light source adjustment frame for testing glass fluorescent sheets includes a base 1. A through slot 2 is provided inside the base 1, and a dual-head motor 3 is installed inside the through slot 2. Two drive shafts 4 are fixedly connected to the two output ends of the dual-head motor 3. A drive bevel gear 5 is fixedly connected to the end of the drive shaft 4 away from the dual-head motor 3. Support plates 6 are fixedly connected to the front and rear of the base 1. Two fixed plates 7 are fixedly connected to the top of the support plates 6. A driven shaft 8 is rotatably connected between the two fixed plates 7. A driven bevel gear 10 is fixedly connected to the end of the driven shaft 8 near the drive bevel gear 5. A worm gear 9 is fixedly connected to the middle section of the outer wall of the driven shaft 8. The drive bevel gear 5 meshes with the driven bevel gear 10. A rotating shaft 11 is rotatably connected to the outer wall of the base 1. The end of the rotating shaft 11 away from the base 1 is fixedly connected to the drive bevel gear 5. A worm gear 12 is fixedly connected, and the worm 9 meshes with the worm gear 12. An adjustment assembly 13 is fixedly connected to the outer wall of the rotating shaft 11. Two positioning plates 14 are fixedly connected to the inside of the through groove 2. Two first positioning rings 15 are fixedly connected to the outer wall of the drive shaft 4. The two first positioning rings 15 are located on both sides of the corresponding positioning plates 14. The adjustment assembly 13 includes two rotating rods 1301. A connecting post 1302 is fixedly connected to the top face of the two rotating rods 1301. A connecting plate 1303 is fixedly connected to the middle of the two connecting posts 1302. An electric push rod 1304 is fixedly connected to the top of the connecting plate 1303. The electric push rod 1304 control system is a collaborative system integrating command, drive, execution and feedback. Its core working principle begins with the control unit (such as a button, PLC, or microcontroller) issuing a command signal; this signal is then transmitted to the driver, which converts it into precise power output (such as PWM speed control) to drive the motor to rotate; the torque generated by the motor is converted into linear push-pull motion through the lead screw and nut mechanism inside the push rod. To achieve precise control, the system typically integrates sensors (such as potentiometers or encoders) to monitor the displacement and speed of the push rod in real time and feeds this data back to the controller. The controller compares the feedback value with the target value and adjusts the drive signal in real time, thus forming a closed-loop control to ensure that the push rod can accurately and stably reach the predetermined position, maintain the set speed, or activate overload protection when encountering excessive resistance. In short, the system is commanded by the "brain" (controller), executed by the "muscles" (motor and mechanical structure), and continuously corrected by the "sensors" (sensors), together achieving precise linear motion control. In the known field, the extension and retraction of the electric push rod 1304 is common knowledge. The extended end of the electric push rod 1304 passes through the connecting plate 1303 and is fixedly connected to the mounting plate 1305. A ray lamp 1306 is fixedly connected to the bottom of the mounting plate 1305.

[0021] When the dual-head motor 3 is started, the drive shaft 4 rotates accordingly, which in turn drives the drive bevel gears 5 at both ends to rotate. The drive bevel gears 5 mesh with the driven bevel gears 10, transmitting power to the driven shaft 8, causing the worm gear 9 fixed on it to rotate synchronously. The worm gear 9 drives the worm wheel 12 meshing with it to rotate, thereby driving the rotating shaft 11 and the adjustment assembly 13 fixed on it to rotate around the bottom of the rotating rod 1301 as the center. The electric push rod 1304 in the adjustment assembly 13 can drive the mounting plate 1305 to rise and fall, thereby adjusting the irradiation height of the X-ray lamp 1306, ultimately realizing automated light irradiation testing of the fluorescent sheet 18 fixed in the arc plate 17 at multiple angles and heights.

[0022] In another embodiment of this utility model, please refer to Figure 3 Two second positioning rings 16 are fixedly connected to the outer wall of the driven shaft 8. The two second positioning rings 16 are located on both sides of the two fixed plates 7 respectively, which improves the stability of the driven shaft 8 when it rotates.

[0023] In another embodiment of this utility model, please refer to Figure 2 The top of the base 1 has a groove 19, which is connected to the through groove 2. Multiple arc-shaped plates 17 are fixedly connected to the top of the groove 19. The multiple arc-shaped plates 17 are evenly distributed in a circumferential array. A fluorescent sheet 18 is placed in the middle of the multiple arc-shaped plates 17, which makes it easy to take out the fluorescent sheet 18 located inside the multiple arc-shaped plates 17.

[0024] In another embodiment of this utility model, please refer to Figure 1 The outer wall of the base 1 is fixedly connected with multiple fixed feet 20, which are symmetrically distributed in pairs.
