Description

Technical Field

[0001] This utility model belongs to the field of crystal detection technology, and specifically relates to a centering adjustment device for crystal detection. Background Technology

[0002] In the field of crystal material preparation, after ingot rounding and end-face grinding, non-contact morphology and dimensional analysis is typically performed using optical imaging and rangefinder sensors. Optical imaging drives the ingot to rotate in stages via a motion axis. The optical lens acquires images segment by segment, and the images are then stitched together to calculate the ingot's diameter and roundness. Before optical imaging, the ingot must be concentrically positioned with respect to the axis of motion to ensure measurement accuracy. The rangefinder sensor drives the ingot to rotate in stages via a rotation axis, while simultaneously using the sensor's horizontal drive axis to drive the rangefinder sensor step-by-step, enabling point cloud scanning and morphology mapping of the ingot's upper surface. This detection also requires the ingot to rotate concentrically with the rotation axis to ensure that the fitted point cloud matches the crystal's shape.

[0003] However, during the rotation of the ingot, radial runout errors can easily occur due to the deviation between the workpiece axis and the rotation axis, leading to optical image distortion and directly affecting the measurement accuracy of key parameters such as surface porosity and grain boundary tilt angle. In addition, existing ingot positioning mainly relies on manual handling in conjunction with dedicated centering fixtures. However, the ingot size range is large (diameter 50-300mm, length 200-800mm), requiring multiple sets of centering fixtures of different sizes, resulting in poor equipment compatibility, low positioning efficiency, and high maintenance costs.

[0004] While some current fixtures employ adjustable jaw structures, their adjustment range is still limited by the mechanical structure, making it difficult to cover the large dimensional tolerances encountered in ingot production. Furthermore, repeated adjustments can easily introduce secondary positioning errors. Therefore, there is an urgent need to develop a centering adjustment device with adaptive centering function for crystal inspection to solve the problem of rapid positioning and rotation center calibration for ingots of various specifications.

[0038] The first pair of center sections 51 includes a first holding end 511, and the second pair of center sections 52 includes a second holding end 521. Both the first holding end 511 and the second holding end 521 are located on the front side of the annular structure and are arranged opposite to each other, together forming a receiving space for accommodating the workpiece.

[0041] The support assembly 1 includes a base plate 11, a support seat 12, an adjusting plate 13, and a guide block 14. The support seat 12 is disposed on the left and right sides of the base plate 11.

[0042] The guide rail assembly 2 includes a rail 22, a support beam 21, and a limiting plate 23. The support beam 21 includes two beam units that correspond one-to-one with the support base 12. The outer end of the beam unit is connected to the top of the corresponding support base 12, and the inner end extends between the two support bases 12. The axes of the two beam units are on the same straight line, and a gap is provided between them. The inner end of the beam unit is located close to the receiving space on its outer side to avoid interference with the receiving space.

[0043] The outer end of the beam unit is provided with an oblong hole running in the left-right direction. A fixing bolt is installed in the oblong hole and is threaded to the support seat 12. The oblong hole provides the beam unit with fine-tuning space in the left-right direction.

[0044] The track 22 includes two track units corresponding to the slider 53, and the track units are respectively set on the corresponding beam units. Preferably, limiting plates 23 are provided at both ends of the track units to prevent the slider 53 from slipping off the track units.

[0045] The synchronous belts 33 located at the front and rear of the annular structure move in opposite directions, and their lengths in the left-right direction are greater than the length of the track unit. The clamping plates 54 on the first pair of middle sections 51 are connected to the synchronous belts 33 at the front of the annular structure, and the clamping plates 54 on the second pair of middle sections 52 are connected to the synchronous belts 33 at the rear of the annular structure, so as to drive the first pair of middle sections 51 and the second pair of middle sections 52 to move in opposite directions in the left-right direction.

[0046] An mounting plate is provided on the support base 12. The mounting plate is located at the bottom of the support beam 21. Two idler wheels 32 are provided on it along the front-back direction. The idler wheel 32 located in front is provided on the inner side of the end of the track unit connected to the second pair of middle parts 52, so that the synchronous belt 33 turns backward and to the left in sequence at the end of the track unit, so that the ring structure is misaligned with the accommodating space in the horizontal direction.

[0047] The slider 53 connected to the second pair of middle parts 52 is located inside the annular structure, while the slider 53 connected to the first pair of middle parts 51 is located outside the annular structure, thus avoiding interference between the front synchronous belt 33 and the connection between the slider 53 and the clamp 54.

[0048] The beam units and track units are disconnected, which facilitates the adjustment of the position on one side and avoids interference with the longitudinal direction of the accommodating space, thus affecting the positioning of the workpiece.

[0049] The drive assembly 4 includes a motor 41, a photoelectric switch 42, a sensing plate 43, and a reducer 44. The reducer 44 is mounted on the support base 12 and is connected to the synchronous pulley 31 via a transmission connection. The motor 41 is connected to the synchronous pulley 31 via the reducer 44 to drive the synchronous pulley 31 to rotate. The photoelectric switch 42 is mounted on the support beam 21 and is electrically connected to the motor 41. The sensing plate 43 is mounted on the first pair of center sections 51, and the photoelectric switch 42 detects the position of the sensing plate 43.

[0050] When using this device for the first time, a pre-alignment adjustment is required. The specific method is as follows:

[0051] (1) Place the workpiece in the ideal working position, and use the workpiece as a reference to start the motor 41, which drives the first pair of middle parts 51 and the second pair of middle parts 52 to move towards each other, so that the contact rollers 55 contact the surface of the workpiece.

[0052] (2) Adjust the position of the support unit so that there is a gap of about 2mm between the limiting plate 23 at the inner end of the support unit and the slider 53;

[0053] (3) Adjust the position of the support seat 12 by adjusting the bolts to make the timing belt 33 tensioned. After adjusting to the position, rotate the tightening bolt to lock the position of the support seat 12.

[0054] (4) If the left and right contact rollers 55 are offset after adjustment, the positioning bolts on the slider 53 can be adjusted to move the first pair of middle parts 51 and the second pair of middle parts 52 until the contact rollers 55 re-contact the workpiece, and then the positioning bolts can be tightened.

[0055] (5) The motor 41 drives the first pair of middle parts 51 and the second pair of middle parts 52 to move away from each other until the slider 53 contacts the limiting plate 23 at the outer end of the track unit.

[0056] (6) The position of the sensor plate 43 is collected by the photoelectric switch 42 and used as the zero point of the motor 41. The pre-alignment adjustment is now complete.

[0057] After the pre-alignment adjustment is completed, when it is necessary to test the crystal, place the workpiece between the first pair of centering parts 51 and the second pair of centering parts 52, start the motor 41, and drive the first pair of centering parts 51 and the second pair of centering parts 52 to move towards each other, so that the contact rollers 55 on the first pair of centering parts 51 and the second pair of centering parts 52 are in contact with the surface of the workpiece, thus achieving the ideal detection position of the workpiece.
