The second correction component 32 includes an opposite second correction cylinder 321 and a second positioning plate 322; the second correction cylinder 321 and the The second positioning plates 322 are respectively provided on both sides of the support rail 2 .

As can be seen from the above description, the beneficial effect of the present invention is to provide a correction and positioning assembly and method, which divides the correction process into primary correction and secondary correction, and performs preliminary positioning of the single crystal silicon rod through the first correction cylinder and the first positioning plate. , and then the second correction cylinder and the second positioning plate are used to position the single crystal silicon rod for a second time to share the force of the single crystal silicon rod during the positioning process, prevent damage, and improve the positioning accuracy.

Further, the support rail 2 includes a ball support rail 21 and a flexible support rail 22 that are supported along the axial direction of the support rail. The ball support rail 21 is located between the first correction cylinder 311 and the first positioning plate. 312 , the flexible support rail 22 is located between the second correction cylinder 321 and the second positioning plate 322 .

It can be seen from the above description that the friction force generated by the single crystal silicon rod during the correction process is reduced through the setting of the ball support rail, and at the same time, the first correction component is used to perform preliminary correction of the single crystal silicon rod; after the preliminary positioning is completed, the flexible support is used The rail changes the dynamic friction between the single crystal silicon rod and the track from dynamic friction to static friction. At the same time, the second correction component is used to fine-tune the position of the single crystal silicon rod and clamp it to complete the final positioning and reduce the material loss of the single crystal silicon rod during the correction process. Loss is taken into account to achieve corrective positioning effect.

Further, the installation platform 1 is provided with an installation slot 11, and both the first positioning plate 312 and the second positioning plate 322 are detachably connected to the installation platform 1 through the installation slot 11;

The axis of the mounting slot 11 is parallel to the axis of the support rail 2; there are multiple mounting slots 11, and the mounting slots 11 follow the first predetermined direction along the direction perpendicular to the axis of the support rail 2. Set the spacing in sequence.

As can be seen from the above description, in order to adapt to single crystal silicon rods of different sizes, the positioning plate is detachably connected to the mounting platform 1 through the mounting groove 11. At the same time, the axis of the mounting groove 11 is parallel to the axis of the support rail 2 and along the axis perpendicular to the support rail. The direction of the axis of 2 is provided in sequence according to the first preset spacing (that is, multiple mounting grooves 11 of positioning plates are provided in the width direction of the single crystal silicon rod), so that the actual width of the single crystal silicon rod can be determined. The positioning plates are arranged in different installation slots 11 to ensure that the center of gravity of the single crystal silicon rod is always located on the support rail 2 and prevent the single crystal silicon rod from falling off the support rail 2 during the correction and positioning process.

Further, the projection perpendicular to the axial direction of the support rail is a first projection plane. On the first projection plane, the horizontal distance between the installation position of the first positioning plate and the center of the support rail is less than the The horizontal distance between the installation position of the second positioning plate and the center of the support rail.

It can be seen from the above description that in order to prevent wear between the single crystal silicon rod and the positioning plate, the horizontal distance between the installation position of the first positioning plate and the center of the support rail is smaller than the horizontal distance between the installation position of the second positioning plate and the center of the support rail. The principle is: after the single crystal silicon rod is initially positioned in the first correction cylinder 311 and the first positioning plate 312, the side surface of the single crystal silicon rod is attached to the first positioning plate 312. In order to prevent the single crystal silicon rod from being If the side of the rod collides with the second positioning plate 322 or generates large friction, causing damage to the single crystal silicon rod, the minimum distance between the second positioning plate 322 and the support rail 2 is controlled to be greater than the minimum distance between the first positioning plate 312 and the support rail 2 .

The principle is to prevent defects or inclinations on the sides of the detected single crystal silicon rods, which would lead to large errors in distance sensing. , use the two distance sensing parts 61 in the vertical direction to project and sense the side of the single crystal silicon rod at the same time, and obtain the through-beam distance (the distance between the distance sensing part 61 and the side of the single crystal silicon rod) respectively. If the two are different, Then, the average of the two through-beam distances is taken as the final through-beam distance, and the midpoint between the two distance sensing units 61 is taken as the sampling point.

In a certain embodiment of the present invention, the zero position is located at the head of the ball support rail.

Further, the step S32 is specifically:

When one side of the distance sensing sensor 6 detects the rod tail of the adjacent surface of the single crystal silicon rod, record the traveling distance U ₁ of the slide 4 at this time; when the other side of the distance sensing sensor 6 detects the adjacent surface of the single crystal silicon rod When the end of the stick is reached, record the traveling distance U ₂ of the slide 4 at this time;
