Description

Technical Field

[0001] This invention relates to a detection system, and more particularly to a detection system and method for finished crystal spheres. Background Technology

[0002] Currently, various growth processes and methods are available for different crystals. While the principles of different crystal growth methods are similar, they differ slightly and can be categorized into vapor phase methods, solution methods, melt methods, epitaxial methods, etc. Important artificial crystal materials such as sapphire single crystals, yttrium aluminum garnet single crystals, silicon-germanium single crystals, and calcium fluoride single crystals can already be obtained through crystal growth technology. Currently, completed crystals require dimensional inspection and internal growth testing using laser light. During growth testing, inspectors must hold a laser lamp and shine light into the crystal, observing the crystal structure directly with the naked eye. This method is quite harmful to the eyes. For dimensional inspection, inspectors must directly measure the crystal size using calipers or other tools, but manual measurement inevitably introduces errors, affecting the accuracy of crystal size detection. Therefore, a detection system and method for finished crystal spheres are proposed. This system eliminates the need for inspectors to move the crystal spheres back and forth, reducing the risk of drops during manual handling. It can accurately detect the size of crystal spheres and simultaneously acquire images of the crystal spheres to assist inspectors in their testing, without requiring them to directly observe the light reflected from within the crystal.

[0035] The crystal moving device transports the crystal ball 1 between the dimensional measuring device and the image acquisition device, eliminating the need for manual handling and reducing the risk of the crystal ball 1 falling. Simultaneously, the crystal moving device rotates the crystal ball 1, facilitating the image acquisition device to capture images of the crystal ball 1 at different positions, enabling the dimensional measuring device to perform dimensional inspections at various locations. The dimensional measuring device measures the length and diameter of the crystal ball 1 on the crystal moving device, reducing manual intervention and effectively improving the accuracy and reliability of dimensional inspection.

A USB interface facilitates the export of the crystal ball 1's dimensional data and image data.

[0039] The position switching mechanism moves the long strip seat 7 laterally, allowing the long strip seat 7 to move the crystal ball 1 between the image acquisition device and the size measurement device, eliminating the need for manual adjustment of the crystal ball 1's position and enabling continuous size detection and image acquisition. The rolling drive unit drives the two cantilever shafts 10 to rotate synchronously and in the same direction, allowing the crystal ball 1 to rotate stably under the action of the two anti-slip sleeves 11, thus realizing the rotation drive of the crystal ball 1. This facilitates the image acquisition device to acquire images of the crystal ball 1 at different positions, and at the same time, it facilitates the size measurement device to perform size detection of the crystal ball 1 at different positions.

[0040] The switching drive motor 47 operates under the control of the controller, causing the switching gear rack pair to drive the placement of the long strip seat 7 to slide along the position switching track 46, thereby realizing the movement drive of the placement of the long strip seat 7, so that the crystal ball 1 can switch positions between the image acquisition device and the size measurement device.

[0041] The rolling drive motor 8 operates under the control of the controller, driving the rolling drive screw 9 to drive the two cantilever shafts 10 to rotate synchronously and in the same direction through two rolling bevel gear transmission pairs, thereby realizing the rotation drive of the two cantilever shafts 10.

On the top; anti-loosening nuts 18 are threaded onto both positioning screws 17 for preventing loosening; anti-detachment limiting discs 13 are fixed to the rear ends of both cantilever shafts 10; anti-detachment pressure springs 12 sleeved on the corresponding cantilever shafts 10 are elastically supported between the two anti-detachment limiting discs 13 and the corresponding anti-detachment limiting tubes 14; the two anti-detachment pressure springs 12 are used to drive the two anti-detachment limiting tubes 14 to move the anti-detachment limiting rods 15, so that the pressing wheel 16 on the anti-detachment limiting rod 15 moves closer to the other pressing wheel 16, and the edges of the two pressing wheels 16 press against the two end faces of the crystal ball 1 respectively.

[0043] Two anti-detachment pressure springs 12 are used to support the two anti-detachment limiting discs 13 and the corresponding anti-detachment limiting tubes 14. The anti-detachment limiting rod 15 is driven to approach the long strip seat 7, so that the two pressing wheels 16 press lightly on the two end faces of the crystal ball 1, which has a positioning effect on the crystal ball 1. The pressing wheels 16 will rotate with the crystal ball 1 without affecting the rotation of the crystal ball 1.

[0044] Furthermore, the size measuring device includes a measuring adjustment mechanism and two distance sensors 31; the measuring adjustment mechanism is mounted on the inspection table 2 and controlled by a controller; the two distance sensors 31 are mounted opposite each other on the measuring adjustment mechanism and are both electrically connected to the controller, and the measuring adjustment mechanism simultaneously adjusts the positions of the two distance sensors 31; the detection ends of the two distance sensors 31 are opposite each other, and the connecting line of the detection ends of the two distance sensors 31 is used to intersect with the axis of the crystal ball 1.

[0045] By using two ranging sensors 31 positioned opposite each other, with their detection ends facing each other and the line connecting the detection ends intersecting the axis of the crystal ball 1, the diameter and length of the crystal ball 1 can be detected. At the same time, the measuring and adjusting mechanism adjusts the positions of the two ranging sensors 31, enabling the measurement of the dimensions of the crystal ball 1 at different axial positions, thereby improving the accuracy of the dimension measurement.

[0047] The rotary drive motor 22 operates under the control of the controller, which drives the rotary drive column 21 to rotate through the worm gear transmission pair. This causes the L-shaped support rod 23 to rotate the synchronous translation branch, thereby realizing the rotational adjustment of the two distance sensors 31 and switching between diameter detection and length detection of the crystal ball 1.

[0048] Furthermore, the synchronous translation branch includes a translation drive unit, a central connecting pipe 24, and two translation branch pipes 26; the translation drive unit includes a translation drive motor 25, a synchronous drive shaft 27, and two synchronous drive lead screws 28.

[0053] The system uses a high-definition camera 39 to capture images of the crystal sphere 1, and a laser lamp 45 to illuminate the crystal sphere 1, allowing inspectors to analyze the growth of the crystal sphere 1 by observing the light scattering within the crystal sphere 1. A crystal rolling mechanism rotates the crystal in place, and a collection and adjustment mechanism moves the laser lamp 45, allowing light to enter the crystal sphere 1 at different positions. This enables the high-definition camera 39 to capture images of the crystal sphere 1 at different locations illuminated by light, further aiding in analysis. Compared to traditional detection methods, this system eliminates the need for inspectors to directly view the light reflected from the laser lamp 45 within the crystal sphere 1, reducing the risk of eye damage.
