[0023] refer to Figure 2 In some embodiments of the present specification, the crystal detection device may include a base 110, a rotating platform 120, a bracket 130 and a line drawing mechanism 140. The rotating platform 120 is rotatably disposed on the base 110, and the rotating platform 120 is used to place the crystal, and then the crystal is driven to rotate relative to the base 110 by the rotation of the rotating platform 120 relative to the base 110, so that the user can adjust the angle of the crystal. The bracket 130 is used to support the line drawing mechanism 140 to achieve the marking of crystal defects. The bracket 130 includes a supporting mechanism and a sliding rod 131. The supporting mechanism supports the sliding rod 131. The line drawing mechanism 140 is slidably disposed on the sliding rod 131 along the axial direction of the sliding rod 131. The base 110 is used to carry the rotating platform 120. The rotating platform 120 can be rotatably connected to the base 110 through a rotating shaft, a spherical rotating structure, etc. In some embodiments, the rotating platform 120 may have a flat surface for placing the crystal. In other embodiments, the rotating platform 120 may also be designed with other structures so that the crystal can be stably placed on the rotating platform. For details, please refer to the relevant description below.
[0024] The support mechanism may be in the shape of a rod, a column, or other regular or irregular shapes. In some embodiments, taking the support mechanism as a support rod as an example, one end of the support rod may be connected to the base 110, and the other end of the support rod may be connected to the sliding rod 131 to support the sliding rod 131. In some embodiments, the support mechanism may be fixed to other locations (such as peripheral columns or walls) to support the sliding rod 131.
[0025] The marking mechanism 140 can be a component such as a pencil or a ballpoint pen that can leave marks on the crystal. The marking mechanism 140 can be used to conveniently mark defects such as holes, islands, steps, etc. on the crystal. By sliding the marking mechanism 140 along the axial direction of the sliding rod 131 and cooperating with the rotation of the rotating platform 120, it is more convenient to mark defects and mark each quadrant during the marking process, thereby making it more convenient and quick to determine the defect position on the crystal.
[0026] refer to Figure 3 In some embodiments, the rotating platform 120 is connected to the base 110 via the rotating shaft 112. In some embodiments, the rotating platform 120 can rotate along the rotating shaft 112 relative to the base 110, thereby driving the crystal placed on the rotating platform 120 to rotate, so that the user can observe or further mark the crystal. It should be noted that, in some embodiments, the rotating platform 120 can be connected to the base 110 in other ways that can realize that the rotating platform 120 is rotatably arranged on the base 110. For example, the rotating platform 120 can be connected to the base 110 through structures such as bearings, rollers, or ball joints.
[0027] In some embodiments, an angle ruler is provided on the rotating platform 120 and / or the base 110. The angle ruler can reflect the angle at which the rotating platform 120 rotates relative to the base 110. The user can determine the angle of rotation of the rotating platform 120 by the angle ruler, and then determine the angle of rotation of the crystal, so as to achieve more accurate marking of crystal defects. For example, in the process of drawing lines to mark the four quadrants, two orthogonal line segments can be drawn more accurately. In some other embodiments, the angle of rotation between the rotating platform 120 and the base 110 can also be obtained by setting sensors or other methods.
[0028] In some embodiments, for ease of operation, the sliding rod 131 is located on the top of the rotating platform 120 , so that when the bottom end face of the crystal is placed on the rotating platform 120 , the marking mechanism 140 can mark the top end face of the crystal.
[0029] In some embodiments, the rotating shaft 112 extends in the vertical direction, and the axial direction of the sliding rod 131 is perpendicular to the rotating shaft 112. In other words, the sliding rod 131 is arranged in the horizontal direction. Through such a structural design, the crystal can be placed and rotated in the vertical direction, and the line drawing mechanism 140 can slide in the horizontal direction to draw lines, so as to draw accurate line segments to divide quadrants. For the crystal grown from the crystal growth furnace, it is roughly cylindrical, and the above-mentioned structural design can be used to easily draw lines on the end face of the crystal, making the line drawing operation simple and convenient. In some other embodiments, the rotating shaft 112 can also extend in other directions. For example, the rotating shaft 112 can extend in the horizontal direction.
[0030] In some embodiments, a mounting groove 121 for fixing the position of the crystal is provided on the rotating platform 120. The mounting groove 121 prevents the crystal from being displaced or rotated during the detection or defect marking process to ensure the accuracy of the marking. In some embodiments, the structure of the mounting groove 121 can be adapted to the crystal to facilitate the fixing of the crystal. In some embodiments, the rotating platform 120 can also cooperate with the mounting groove 121 through other structures to achieve clamping or clamping of the crystal to fix the crystal position.
[0031] In some embodiments, the rotating platform 120 can be used to place the crystal and the seed crystal holder used when the crystal is grown. During the crystal production process, the seed crystal can be bonded to the surface of the seed crystal holder facing the crucible, and the seed crystal holder can be placed in the crystal growth furnace together with the seed crystal so that the crystal grows on the side of the seed crystal holder facing the crucible. In some embodiments, the seed crystal holder and the crystal can be fixed by the aforementioned mounting groove 121. In some other embodiments, the crystal and the seed crystal holder can also be separated, and only the crystal is fixed to the mounting groove 121.
[0032] In some embodiments, in order to better fix the position of the seed crystal holder and prevent the crystal from moving when the line drawing mechanism 140 draws a line on the crystal, the shape of the mounting groove 121 is configured to match the shape of the seed crystal holder bonded during the crystal growth process. For example, when the seed crystal holder is truncated, the shape of the mounting groove 121 is also truncated; for another example, when the seed crystal holder is cylindrical, the shape of the mounting groove 121 is also cylindrical.
[0033] In some embodiments, a mounting member 122 is provided at the bottom of the mounting groove 121, and the mounting member 122 is used to fix the seed crystal holder. Since the seed crystal holder and the crystal are originally bonded and relatively fixed, the mounting member 122 fixes the seed crystal holder to fix the position of the crystal.
[0034] In some embodiments, the mounting member 122 may be a threaded rod or a screw, and the seed crystal holder is fixed by means of threaded cooperation with the seed crystal holder. Since the seed crystal holder generally has a threaded hole, in the crystal growth furnace, the seed crystal holder is generally connected to the lifting rod (provided with an external thread) by means of a threaded connection. By setting the mounting member 122 as a threaded rod, it can be adapted to the structure (threaded hole) of the seed crystal holder itself, so that the seed crystal holder can be stably fixed in the mounting groove, and the structure of the mounting member 122 can also be simple, and the crystal detection device is easy to manufacture. It should be noted that the mounting member 122 can also be other structures that can achieve the fixation of the seed crystal holder, such as a clamping structure, a pressing structure, etc.
[0035] Since the size, shape and whether the crystal to be detected includes a seed crystal holder may vary in actual scenarios, in some embodiments, the support mechanism is configured to make the distance between the sliding rod 131 and the rotating platform 120 in the vertical direction adjustable. For example, in the case where a seed crystal holder is included and the crystal is relatively long, the support mechanism can be adjusted to increase the distance between the sliding rod 131 and the rotating platform 120 in the vertical direction, thereby expanding the adaptability of the crystal detection device. In some embodiments, the support mechanism can adjust the distance between the sliding rod 131 and the rotating platform 120 in the vertical direction by using a telescopic rod or a gear-rack mechanism.
[0036] In some embodiments, the support mechanism includes a first telescopic rod 133 and a second telescopic rod 134, one end of the first telescopic rod 133 and the second telescopic rod 134 are respectively arranged on the base 110, and the other ends of the first telescopic rod 133 and the second telescopic rod 134 are respectively connected to the two ends of the sliding rod 131; the rotating platform 120 is arranged between the first telescopic rod 133 and the second telescopic rod 134. By providing at least two telescopic rods (the first telescopic rod 133 and the second telescopic rod 134), the telescopic mechanism can support the sliding rod 131 more stably, and can not only adjust the distance between the sliding rod 131 and the rotating platform 120 in the vertical direction, but also adjust the inclination angle of the sliding rod 131 according to the use requirements, so that the crystal detection device can be suitable for detecting crystals of various shapes.
[0037] In some embodiments, the sliding rod 131 is provided with a measuring ruler (not shown) along the axial direction, and the measuring ruler can be used to measure the diameter of the crystal, the aperture size of the hole, the hole spacing and the relative position of the hole.
[0038] In some embodiments, in order to meet actual needs, the measuring ruler is configured to be able to slide along the axial direction of the sliding rod 131. For example, a sliding groove can be provided on the sliding rod 131 along the axial direction of the sliding rod 131, a sliding member is provided in the sliding groove, and the measuring ruler is connected to the sliding member, so that the measuring ruler can slide along the axial direction of the sliding rod 131. By moving the measuring ruler, the diameter of the crystal, the hole size, the hole distance and the relative position of the hole in a larger range can be measured.
[0039] In some embodiments, the measuring ruler is configured to be able to rotate along a horizontal axis that is perpendicular to the axial direction of the sliding rod 131. The measuring ruler can rotate along an axis that is perpendicular to the axial direction of the sliding rod 131, which can change the extension direction of the measuring ruler, that is, the measuring ruler can no longer extend along the axial direction of the sliding rod 131, but form a certain angle with the axial direction of the sliding rod 131, such as an angle of 45°, 60°, 90°, etc. Since the axis is horizontal, this allows the measuring ruler to rotate in a vertical plane and can be switched between a horizontal state and a vertical state, which is suitable for detection scenarios for crystals. Through the rotatable setting of the above-mentioned measuring ruler, the measuring ruler can measure the size of the crystal from different angles. As an example only, one end of the measuring ruler can be connected to the sliding rod through a rotating shaft so that the measuring ruler can switch between the state of extending along the axial direction of the sliding rod and extending along the vertical direction.
[0040] In some embodiments, the measuring ruler can slide relative to the sliding rod 131 (such as sliding along the extension direction of the measuring ruler), and can also rotate along a horizontal axis that is perpendicular to the axial direction of the sliding rod 131, so that the rotated measuring ruler can adjust its position relative to the sliding rod. For example, when the measuring ruler is rotated to extend in the vertical direction, the measuring ruler can also slide in the up and down direction relative to the sliding rod 131, which can more conveniently adjust the measuring angle and measuring position of the measuring ruler. As an example only, a guide groove and a sliding block are provided on the measuring ruler, and the sliding block is slidably connected to the guide groove. The sliding block is rotatably connected to the sliding rod 131, and the rotation of the sliding block relative to the sliding rod 131 will drive the measuring ruler to rotate synchronously. The sliding block can slide in the guide groove, and the sliding measuring ruler, the cooperation of the guide groove and the sliding block can ensure that the measuring ruler slides along the extension direction of the measuring ruler, and ensure that the measuring ruler and the sliding rod 131 do not separate.
[0041] The basic concepts have been described above. Obviously, for those skilled in the art, the above detailed disclosure is only for example and does not constitute a limitation of this specification. Although not explicitly stated here, those skilled in the art may make various modifications, improvements and corrections to this specification. Such modifications, improvements and corrections are suggested in this specification, so such modifications, improvements and corrections still belong to the spirit and scope of the exemplary embodiments of this specification.
