Abstract
Description
Technical Field
[0001] This utility model relates to the field of crystal testing technology, and more specifically, to a closed backlight observation device for crystal blank test pieces. Background Technology
[0002] During crystal growth, it is sometimes necessary to observe the crystal blank. When observing the crystal blank, it must be placed in a closed environment with a single light source directed directly at it. This prevents the crystal blank from being affected by light sources from other directions, which could influence the observation results. Furthermore, the thickness of the crystal blank will vary each time it is observed. Observing crystal blanks of different thicknesses requires adjusting the distance between the light source and the crystal blank to ensure the crystal blank is positioned optimally for observation.
[0003] In practice, most of the equipment used to observe crystal blanks is relatively simple, and some cannot guarantee that the crystal blank is in a closed environment; at the same time, some existing equipment is not convenient for timely adjustment of the distance between the light source and the crystal blank.

Detailed Implementation
[0017] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0018] Please see Figure 1 and Figure 2 This utility model provides a technical solution:
[0019] A closed-type backlit observation device for crystal blank test pieces includes an observation tube 1 with a head end and an end end. The head end of the observation tube 1 is an observation port 2, and the end end of the observation tube 1 is fitted with an equipment box 6 to block the end of the observation tube 1. A tray 4 for placing the crystal blank 3 is installed inside the observation tube 1 near its head end. The observation tube 1 also has a notch on the tray 4 for placing the crystal blank 3 inside the observation tube 1, and a light-shielding plate 10 is hinged within the notch. When the crystal blank 3 needs to be placed on the tray 4, the light-shielding plate 10 is opened. The observation tube 1 also includes a light source 5 that directs light towards the tray 4, and a control mechanism that controls the movement of the light source 5 within the observation tube 1. The movement direction of the light source 5 is parallel to the central axis of the observation tube 1. This allows the distance between the light source 5 and the crystal blank 3 to be adjusted according to the thickness of the crystal blank 3, ensuring that crystal blanks of different thicknesses are placed on the tray 4 under optimal observation brightness.
[0020] Specifically, the control mechanism includes a gear mechanism installed inside the equipment housing 6 and an actuator installed inside the observation cylinder 1. Figure 2 From the perspective of the device housing 6, in this embodiment, a first rotating shaft 7 is rotatably mounted inside the equipment housing 6. The central axis of the first rotating shaft 7 is collinear with the central axis of the observation tube 1. The left end of the first rotating shaft 7 is located inside the equipment housing 6, and its right end is located inside the observation tube 1. The gear mechanism includes a driving gear (not shown in the figure) rotatably mounted inside the equipment housing 6 and a driven gear 8 mounted on the end of the first rotating shaft 7 located inside the equipment housing 6. The driven gear 8 meshes with the driving gear.
[0021] from Figure 2From the perspective of the device, the actuator includes a second rotating shaft 901 fixedly installed inside the observation cylinder 1, a rotating cylinder 902 rotatably connected to the second rotating shaft 901, a first bevel gear 903 fixedly installed on the second rotating shaft 901, a second bevel gear 904 fixedly installed on the first rotating shaft 7, and a lever 905 installed at the end of the second bevel gear 904. The second bevel gear 904 meshes with the first bevel gear 903. An annular groove 906 is formed on the inner wall of the rotating cylinder 902. The central axis of the first bevel gear 903, the central axis of the second rotating shaft 901, the central axis of the annular groove 906, and the central axis of the rotating cylinder 902 are all collinear with the central axis of the first rotating shaft 7. The central axis of the lever 905 is parallel to and not collinear with the central axis of the second bevel gear 904 (that is, the lever 905 is eccentrically installed relative to the central axis of the second bevel gear 904), and the central axis of the lever 905 is perpendicular to the central axis of the first rotating shaft 7. The light source 5 is installed at the right end of the rotating cylinder 902.
[0022] In this embodiment, to facilitate the rotation of the drive gear, an operating lever 11 is also provided through the equipment housing 6. The operating lever 11 is rotatably connected to the equipment housing 6, and the drive gear is installed at one end of the operating lever 11 located inside the equipment housing 6. In other embodiments of this embodiment, the forward and reverse rotation of the drive gear can also be controlled by a motor.
[0023] Working principle:
[0024] from Figure 2 From the perspective of the user, the crystal blank 3 is first placed on the tray 4, and then the light shield 10 is used to cover the gap. The user's eye is then aligned with the observation port 2, with the viewing angle from right to left. If the amount of light received by the crystal blank 3 needs to be adjusted, the operating lever 11 can be manually rotated, causing the first rotating shaft 7 to rotate synchronously under the drive of the gear mechanism. During the rotation of the first rotating shaft 7, the second bevel gear 904 rotates around the central axis of the first rotating shaft 7. During this process, the end of the lever 905 away from the second bevel gear 904 moves within the annular groove 906. However, due to the presence of the first bevel gear 903, the second bevel gear 904 also rotates around its own central axis while rotating around the central axis of the first rotating shaft 7. Because the lever 905 is eccentrically mounted, the position of the lever 905 in the left-right direction changes during the operation of the second bevel gear 904. This, through the annular groove 906, causes the rotating cylinder 902 to move in the left-right direction, so that the light source 5 is closer to or further away from the crystal blank 3, ensuring the crystal blank 3 receives the optimal amount of light.
