[0039] The housing 100 in the crystal detection device may include a cavity a1, an opening a2 communicating with the cavity a1, and a top cover 101 located at the opening a2 of the housing 100. The top cover 101 may have a first light-transmitting area a3. Here, the housing 100 may be made of an opaque material, or the inner sidewalls of the housing 100 may be coated with an opaque material such as ink to ensure a darkroom within the housing 100.

[0040] The mounting frame 200 in the crystal detection equipment can be fixed at the bottom of the cavity a1 of the box body 100 and can be arranged opposite to the opening a2 of the box body 100. The mounting frame 200 can have a first light-transmitting hole 201 corresponding to the first light-transmitting area a3 of the top cover 101, and the polarizer 400 in the crystal detection equipment can be fixed in the first light-transmitting hole 201 of the mounting frame 200.

[0041] The first light source 300 in the crystal detection device can be fixed to the bottom of the cavity a1 of the housing 100, and the light emitting surface of the first light source 300 can face the polarizer 400 in the first light hole 201. For example, the first light source 300 can be a light source that emits white light or yellow light, for example, the first light source 300 can be a first laser light source.

[0042] The crystal carrier 500 in the crystal detection equipment can be connected to the side of the mounting frame 200 close to the opening a2 of the box body 100, and the second light source 600 can be located at the side of the crystal carrier 500 and can be movably connected to the inner wall of the box body 100. The crystal carrier 500 can have a second light-transmitting area b1 corresponding to the first light-through hole 201 of the mounting frame 200, and a third light-transmitting area b2 corresponding to the light-emitting surface of the second light source 600. Here, the crystal carrier 500 can be used to fix the crystal to be tested, and the crystal to be tested is located in the area of ​​the second light-transmitting area b1 of the crystal carrier 500. For example, the second light source 600 can emit at least one of red light, green light and purple light, and emit light of different colors according to the detection requirements of the crystal to be tested. For example, the second light source 600 can be a second laser light source.

[0043] The analyzer 700 in the crystal detection device can be rotatably connected to the top cover 101, and the light receiving surface of the analyzer 700 can face the first light transmission area a3 of the top cover 101. For example, the polarizer 400 in the crystal detection device can be a polarizing plate, and the analyzer 700 can be a vibration detector plate.

[0044] The crystal detection device may have a first detection state and a second detection state. When the crystal detection device is in the first detection state, the first light source 300 can emit a first light ray to the crystal to be tested through the polarizer 400 in the first light hole 201 and the second light-transmitting area b1 of the crystal carrier 500. When the crystal detection device is in the second detection state, the second light source 600 can emit a second light ray to the crystal to be tested through the third light-transmitting area b2 of the crystal carrier 500. It should be noted that when the crystal detection device is in the first detection state, the first light source 300 works normally, and the second light source 600 is in a non-light-emitting state; when the crystal detection device is in the second detection state, the second light source 600 works normally, and the first light source 300 is in a non-light-emitting state.

[0045] In an embodiment of the present application, after placing the crystal to be tested on the crystal carrier 500 through the opening a2 of the housing 100, the operator controls the crystal detection device to be in the first detection state. At this time, the first light emitted by the first light source 300 can pass through the polarizer 400 and the second light-transmitting area b1 to be emitted toward the crystal to be tested, and after the first light passes through the crystal to be tested, it is emitted from the first light-transmitting area a3 of the top cover 101 to the analyzer 700. The operator synchronously rotates the analyzer 700 and observes the stress condition of the crystal to be tested and the light cone condition of the directional growth of the crystal through the shape of the light beam presented on the analyzer 700. Afterwards, the operator controls the crystal detection device to be in the second detection state. The second light source 600, which is movably connected to the housing 100, can move to emit the second light to different positions of the crystal to be tested. The second light passes through the crystal to be tested and then turns and is emitted to the analyzer 700. The shape of the light beam presented by the analyzer 700 is used to observe the light column, scattered particles, bubbles and other phenomena of the crystal to be tested. In this way, by integrating two light sources and a crystal carrier 500 for carrying the crystal to be tested in the box 100, and arranging a polarizer 700 on the top cover 101 of the box 100, when the crystal detection equipment is controlled to be in different detection states, the crystal to be tested is illuminated by different light sources, and the shape of the light beam is observed on the polarizer 700 to detect different performance states of the crystal to be tested, thereby increasing the functional diversity of the crystal detection equipment, improving the efficiency of the preliminary classification of crystals, saving corporate costs, and providing a better reference significance for further crystal preparation processes.

[0046] In summary, the embodiment of the present application provides a crystal detection device, which may include: a box, a mounting frame, a first light source, a polarizer, a crystal carrier, a second light source and an analyzer. After the crystal to be tested is placed on the crystal carrier through the opening of the box, the operator controls the crystal detection device to be in the first detection state, at which time the first light emitted by the first light source can pass through the polarizer and the second light-transmitting area to be emitted toward the crystal to be tested, and after the first light passes through the crystal to be tested, it is emitted from the first light-transmitting area of ​​the top cover to the analyzer, and the operator synchronously rotates the analyzer, and observes the stress condition of the crystal to be tested and the light cone condition of the directional growth of the crystal through the shape of the light beam presented by the analyzer. Afterwards, the operator controls the crystal detection device to be in the second detection state, and the second light source movably connected to the box can be moved to emit the second light to different positions of the crystal to be tested, and the second light passes through the crystal to be tested and then turns toward the analyzer, and observes the light column, scattered particles and bubbles in the crystal to be tested through the shape of the light beam presented by the analyzer. In this way, by integrating two light sources and a crystal carrier for carrying the crystal to be tested in the box, and arranging a polarizer on the top cover of the box, when the crystal detection equipment is controlled to be in different detection states, different light sources are used to illuminate the crystal to be tested, and the shape of the light beam is observed on the polarizer to detect different performance states of the crystal to be tested, thereby increasing the functional diversity of the crystal detection equipment, improving the efficiency of the preliminary classification of crystals, saving enterprise costs, and providing a better reference significance for further crystal preparation processes.

[0047] In this application, please refer to Figure 3 , Figure 3 1 is a cross-sectional view of another crystal detection device provided in an embodiment of the present application. One side of the top cover 101 may have a support column 101a and a support frame 101b rotatably connected to the support column 101a, and the polarizer 700 may be fixed on the support frame 101b. In this way, the rotation of the polarizer 700 is achieved by the rotational connection between the support frame 101b and the support column 101a. For example, the support frame 101b can be sleeved on the support column 101a through a rotating bearing (not shown in the figure) to achieve stable rotation with the support frame 101b.

[0048] Optional, such as Figure 3 As shown, crystal carrier 500 can be a square shell with a housing c1. A crystal to be tested can be secured to the bottom of the housing c1 of crystal carrier 500. The bottom of crystal carrier 500 can have a second light-transmitting region b1, and the sides of crystal carrier 500 can have a third light-transmitting region b2. Thus, by placing the crystal to be tested within housing c1 of crystal carrier 500, crystal carrier 500 can provide a certain degree of protection for the crystal to be tested.

[0049] In the present application, the crystal testing apparatus may further include: a transparent liquid injected into the accommodating cavity c1 of the crystal carrier 500 for soaking the crystal to be tested. In this case, by injecting the transparent liquid into the accommodating cavity c1 of the crystal carrier 500 and placing the crystal to be tested within the transparent liquid, the cleanliness of the crystal to be tested can be ensured, thereby ensuring a good testing effect on the crystal to be tested.

[0050] Optional, please refer to Figure 4 , Figure 4 is a cross-sectional view of another crystal testing device provided by an embodiment of the present application. The crystal testing device may further include: a tilt angle adjustment assembly 800 and a rotation angle adjustment assembly 900 located between the crystal carrier 500 and the mounting frame 200. One end of the tilt angle adjustment assembly 800 may be connected to the bottom of the crystal carrier 500, and the rotation angle adjustment assembly 900 may be connected to the tilt angle adjustment assembly 800 and the mounting frame 200, respectively. The rotation angle adjustment assembly 900 may have a second light hole d1 that communicates with the first light hole 201 of the mounting frame 200, and the tilt angle adjustment assembly 800 may have a third light hole d2 that communicates with the second light hole d1.

[0051] The tilt angle adjustment component 800 can be configured to drive the crystal carrier 500 to swing so as to adjust the angle between the central axis L1 of the crystal carrier 500 and the optical axis L2 of the first light source 300. The rotation angle adjustment component 900 can be configured to drive the tilt angle adjustment component 800 and the crystal carrier 500 to rotate synchronously around the optical axis L2 of the first light source 300. In this case, by providing the tilt angle adjustment component 800 and the rotation angle adjustment component 900 in the crystal detection device, the rotation angle adjustment component 900 can be controlled to drive the tilt angle adjustment component 800 and the crystal carrier 500 to rotate a certain angle in the horizontal plane, thereby achieving a coarse adjustment of the position of the crystal to be tested; thereafter, the tilt angle adjustment component 800 can be controlled to drive the crystal carrier 500 to swing so as to finely adjust the position of the crystal to be tested, thereby enabling detection of whether there is a fault phenomenon inside the crystal to be tested.

[0052] In the embodiments of this application, Figure 4As shown, the tilt angle adjustment assembly 800 may include: a first sliding table 801, a second sliding table 802, a transmission member (not shown), and a first drive assembly 803. The first sliding table 801 may have a first curved surface e1 and a first sub-hole e2. The second sliding table 802 may have a second curved surface e3 that slides with the first curved surface e1 of the first sliding table 801, and a second sub-hole e4 that communicates with the first sub-hole e2 of the first sliding table 801. The first sub-hole e2 and the second sub-hole e4 may form a third light-clearing hole d2. The surface of the first sliding table 801 facing away from the second sliding table 802 may be fixedly connected to the crystal carrier 500, and the surface of the second sliding table 802 facing away from the first sliding table 801 may be fixedly connected to the rotation angle adjustment assembly 900. The transmission member may be located between the first sliding table 801 and the second sliding table 802 and may be in transmission connection with the first sliding table 801 and the second sliding table 802, respectively. The first drive assembly 803 may be in transmission connection with the transmission member. The first driving assembly 803 may be configured to drive the first sliding platform 801 to slide relative to the second sliding platform 802 on the second curved surface e3 of the second sliding platform 802 through a transmission member.

[0053] In this case, when the tilt angle adjustment component 800 is required to drive the crystal to be measured to swing, the first drive component 803 is controlled to drive the first sliding table 801 through the first curved surface e1 and the second curved surface e3 of the second sliding table 802 through the transmission member, so that the first sliding table 801 can swing along the second curved surface e3 relative to the second sliding table 802. For example, the first drive component 803 may include a drive motor, and the transmission member may include: a worm gear and a worm that cooperate with each other, the worm gear can be sleeved on the worm and fixedly connected to the first sliding table 801, the worm can be connected to the second sliding table 802, and the end of the worm can be transmission-connected to the first drive component 803. In this way, after receiving the instruction issued by the operator, the first drive component drives the first sliding table 801 to slide a certain angle relative to the second sliding table 802 through the transmission member, thereby achieving the swing of the crystal carrier 500 and the crystal to be measured. It should be noted that the transmission member and the first drive component in the tilt angle adjustment component 800 can also be other structures, and the embodiments of the present application do not specifically limit this. For example, the first sliding platform 801 is driven by the telescopic rod of the telescopic cylinder to slide on the second arc surface e3 of the second sliding platform 802.

[0054] Optional, such as Figure 4As shown, the rotation angle adjustment assembly 900 may include: a first rotation support member 901 and a second rotation support member 902 stacked and rotatably connected along the optical axis of the first light source 300, and a second drive assembly 903. The first rotation support member 901 may have a third sub-aperture f1, and the second rotation support member 902 may have a fourth sub-aperture f2 connected to the third sub-aperture f1. The third sub-aperture f1 and the fourth sub-aperture f2 may form a second light-transmitting aperture d1. The surface of the first rotation support member 901 facing away from the second rotation support member 902 may be fixedly connected to the tilt angle adjustment assembly 800, and the surface of the second rotation support member 902 facing away from the first rotation support member 901 may be fixedly connected to the mounting bracket 200. The second drive assembly 903 is fixed within the cavity a1 of the housing 100 and may be in transmission connection with the first rotation support member 901. The second drive assembly 903 may be configured to drive the first rotation support member 901 to rotate relative to the second rotation support member 902, thereby driving the crystal carrier 500 to rotate. In this case, by setting a first rotating support member 901 and a second rotating support member 902 that are rotatably connected to each other in the rotation angle adjustment component 900, the second driving component 903 drives the first rotating support member 901 to rotate relative to the second rotating support member 902 after receiving the operator's instructions, thereby realizing the function of driving the crystal carrier 500 and the crystal to be measured to rotate.

[0055] Here, the side of the first rotating support member 901 facing away from the second rotating support member 902 can be fixedly connected to the second sliding platform 802 in the tilt angle adjustment assembly 800. The rotation angle adjustment assembly 900 can also include: a plurality of rolling elements (not shown in the figure) located between the first rotating support member 901 and the second rotating support member 902, and the plurality of rolling elements can be slidably connected to the first rotating support member 901 and the second rotating support member 902. It should be noted that the two rotating supports and the plurality of rolling elements in the rotation angle adjustment assembly 900 can form a plane bearing, that is, the second drive assembly 903 can be used in combination with the plane bearing.

The driving gear 903b can be connected with the output shaft of the driving motor 903a and can be in transmission connection with the plurality of driving external teeth 901a. For example, after the driving motor 903a receives a control instruction of an operator, the driving motor 903a drives the driving gear 903b to rotate, and then drives the first rotating support 901 to rotate through the plurality of driving external teeth 901a on the first rotating support 901.

The arrangement direction of the two first guide rails 102 can be parallel to the plane where the opening a2 of the box body 100 is located. The two ends of the second guide rail 103 can be in transmission connection with the two first guide rails 102 respectively, and the second light source 600 can be in sliding connection with the second guide rail 103.

[0061] In summary, the embodiment of the present application provides a crystal detection device, which can include a box body, a mounting frame, a first light source, a polarizer, a crystal carrier, a second light source and a polarimeter. After the to-be-tested crystal is placed on the crystal carrier through the opening of the box body, the operator controls the crystal detection device to be in a first detection state, at which time the first light emitted by the first light source can pass through the polarizer and the second light transmission area to the to-be-tested crystal, and the first light transmits through the to-be-tested crystal to the polarimeter through the first light transmission area of the top cover, and the operator synchronously rotates the polarimeter to observe the stress condition of the to-be-tested crystal and the light cone condition of the crystal directional growth through the shape of the light beam presented by the polarimeter. Then, the operator controls the crystal detection device to be in a second detection state, and the second light source movably connected with the box body can emit second light to different positions of the to-be-tested crystal, and the second light is emitted to the polarimeter after being bent by the to-be-tested crystal, and the light column, scattering particles, bubbles and other phenomena of the to-be-tested crystal are observed through the shape of the light beam presented by the polarimeter. In this way, by integrating two light sources in the box body, and the crystal carrier for carrying the to-be-tested crystal, and setting the polarimeter on the top cover of the box body, when the crystal detection device is controlled to be in different detection states, the to-be-tested crystal is irradiated by different light sources, and the shape of the light beam on the polarimeter is observed to detect different performance states of the to-be-tested crystal, the functional diversity of the crystal detection device is increased, the efficiency of the preliminary classification of the crystal is improved, the enterprise cost is saved, and better reference significance is provided for further crystal preparation process.
