Monocrystalline silicon is a basic material in the information industry, and is widely used in the fields of semiconductors, solar energy, and the like. Monocrystalline silicon is a substance in which silicon atoms are formed in an arrangement. The manufacture of the monocrystalline silicon material mainly comprises the following steps: quartz sand-metallurgical grade silicon-purification and refining-deposition polycrystalline silicon ingot-single crystal silicon rod-silicon segment (piece) cutting. The single crystal silicon rod is formed by shaping or pulling in a hearth through zone melting or Czochralski technology, and is a silicon single crystal rod with silicon atoms rearranged according to the lattice arrangement direction of seed crystals. And the silicon segment (sheet) cutting means that after the silicon rod is formed, the silicon rod is cut into segments or into sheets by a cutting machine head assembly of a cutter (also called a cutting machine, a cutting machine and the like) so as to meet the use of the follow-up links.

The working steps of the cutting machine generally comprise feeding, conveying, supporting, cutting and blanking links from beginning to end, wherein after the silicon rod is conveyed to the lower part of the cutting device through the conveying device, the silicon rod is further supported in place through the supporting device, and then the cutting device is controlled to cut. However, since the silicon rod is generally placed horizontally, the overall axial direction is easily deviated from the horizontal accuracy, or easily deviated from the machining direction (corresponding to the arrangement direction of each cutting device) or easily deviated from the predetermined accuracy on the same horizontal plane, if the deviation is ignored, the flatness of the machined surface of the silicon wafer or the silicon segment and the parallelism of the cut surface of the silicon segment are not good, thereby affecting the machining quality of the back-end process. In addition, in the prior art, the lifting mechanisms are arranged on two sides of the conveying device, so that the position of the conveying device can be adjusted, but generally, the two sides are lifted simultaneously, and the axial level of the axis of the silicon rod is difficult to adjust, so that in general, how to obtain the deviation and apply the deviation to realize the adjustment of the axial state (namely the centering or leveling) of the silicon rod according to the preset level is a difficult problem facing the current industry.

All other embodiments, based on the embodiments herein, which a person of ordinary skill in the art would obtain without undue burden from the person of ordinary skill in the art, are within the scope of protection of the present application. It should be noted that, in the case of no conflict, the embodiments and features in the embodiments may be arbitrarily combined with each other.

The following description refers to fig. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12. As shown in the drawing, the silicon rod aligning system provided in this embodiment of the application may include a silicon rod detecting device, a conveying device 60, a first lifting mechanism 601, a second lifting mechanism 602 and a controller, where the first lifting mechanism 601 includes a first lifting support 619, the second lifting mechanism 602 includes a second lifting support 625, the first lifting support 619 is rotatably supported at the bottom of the first end of the conveying layer 603 of the conveying device 60, the second lifting support 625 is movably supported at the bottom of the second end of the conveying layer 603, the silicon rod detecting device includes two telescopic detecting assemblies respectively disposed at two different cutting head assemblies 50, the telescopic detecting assemblies are used to detect three position point information (corresponding to three detection points) on the same section of the silicon rod 200 in a manner of extending from the cutting head assembly 50, and the controller is used to obtain current axial information of the silicon rod 200 according to the detection results of the two telescopic detecting assemblies, and reduce the deviation of the inclination of the current axial information from a predetermined degree (such as a level degree) by the lifting amplitude of the first lifting mechanism 601 and/or the second lifting mechanism 602.

In operation, after the conveying device 60 conveys the silicon rod to the lower part of the cutting device (each cutting head assembly 50), before cutting, for example, before the supporting device 70 does not act, two telescopic detection assemblies arranged on different cutting head assemblies can be started, three circumscribed position point (corresponding to detection position point) information on the same section of the first group of the silicon rod 200 can be detected and obtained by one telescopic detection assembly, three circumscribed position point information on the same section of the second group of the silicon rod 200 can be detected and obtained by the other telescopic detection assembly, the controller can obtain the three circumscribed position point information, and as the first center point in the corresponding axial direction can be conveniently obtained by the first three circumscribed position points, the second center point in the corresponding axial direction can be conveniently obtained by the second three circumscribed position points, and the connecting line of the two center points represents the current axial state (information) of the silicon rod, so that the controller can easily obtain the current axial state (information) of the silicon rod 200 through calculation, and the current axial state (information) of the silicon rod 200 can be removed according to the preset degree of accuracy, and the preset degree of accuracy can be controlled according to the preset degree of accuracy, and the preset degree of accuracy, namely, the preset degree of accuracy and the degree of accuracy can be controlled according to the preset degree, and the preset degree of accuracy. It should be noted that, according to the principle that two points determine a straight line, a line connecting two center points is used to determine the current axial state of the silicon rod, which is at least two center points, and in other embodiments, a greater number of center point data may be used to determine the current axial state of the silicon rod, and correspondingly, at least two detection assemblies, which may be a greater number of detection assemblies, may be used.

In addition, the first lifting mechanism and the second lifting mechanism on two sides of the conveying mechanism are also prepared in advance in terms of structure, that is, the two lifting mechanisms are not only lifted and adjustable, but also one end of the conveying mechanism can realize supporting rotation, and the other end of the conveying mechanism can realize supporting movement, so that a structural foundation is built for the two lifting mechanisms to lift and lower independently and adjustably, that is, the requirement of height adjustment is met while supporting is considered, for example, when the right end lifting mechanism (corresponding to the second lifting mechanism 602) is not adjusted and the left end lifting mechanism (corresponding to the first lifting mechanism 601) is adjusted to be higher in the drawing, the left end of the conveying layer 603 of the conveying device 60 can adaptively rotate by a preset angle while the first lifting support 619 supports, and the bottom support of the right end of the conveying layer 603 can properly move, so that the two lifting mechanisms can only cooperate and do not interfere with the height adjustment of the left end, otherwise, similarly, therefore, the scheme of the embodiment of the application can realize self-adaptive centering of the silicon rod (adjusting the axial direction of the silicon rod), so that the problem that the processing effect is directly affected due to the fact that the placement accuracy of the silicon rod is not enough (has deviation) can be reduced or effectively avoided.

Referring to fig. 9, as a preferred embodiment, the first lifting mechanism 601 may further include a first base body 611, a first lifting driving part 616, and a rotatable supporting frame, wherein the first lifting supporting frame 619 is disposed on one side of the first base body 611 in a manner of being able to move up and down, the rotatable supporting frame is disposed on the first lifting supporting frame 619, the first end bottom of the conveying layer 603 is mounted on the rotatable supporting frame, the first lifting driving part 616 is used for driving the first lifting supporting frame 619 to lift or descend relative to the first base body 611, and further, the height of one end of the conveying layer 603 is adjusted, and the controller controls the lifting amplitude of the first lifting mechanism by controlling the first lifting driving part 616.

On this basis, the rotatable support frame may further include a rotatable support shaft 620, a first support plate 621 and a second support plate 622, wherein the rotatable support shaft 620 is disposed on the first lifting support frame 619, the first support plate 621 and the second support plate 622 are fixed on the rotatable support shaft 620 at intervals, and two sides of the bottom of the first end of the conveying layer 603 are respectively mounted on the first support plate 621 and the second support plate 622. The structure can be rotated and simultaneously plays a firm supporting role.

There are various ways to realize the lifting of the first lifting support 619 relative to the first base body 611, in the scheme shown in the drawings, the first lifting mechanism 601 includes a screw pair, the first base body 611 includes a first base 6111, a screw 613 of the screw pair is vertically disposed on the first base 6111, the first lifting support 619 is slidingly engaged with one side of the first base 6111 and is fixed with a nut of the screw pair, and the first lifting driving component 616 is used for driving the screw 613 to rotate. In particular, the guide rails 618 may be disposed on two sides of the first base 6111, and the first lifting support 619 may include a sliding fit portion 617 (e.g. a chute), through which the first lifting support 619 is in lifting fit with the guide rails 618.

In addition, there may be various manners in spatial arrangement of the first lifting driving part 616 and driving of the first lifting driving part 616 on the screw 613, fig. 9 shows an implementation manner that saves space and takes into account transmission efficiency, where the first base body 611 further includes a second base 6112 juxtaposed with the first base 6111, an accommodating space is provided in the second base 6112, the first lifting driving part 616 may be a motor, the first lifting driving part 616 is installed in the accommodating space, a first driving wheel 612 connected with the screw 613 is provided on a top side of the first base 6111, a second driving wheel 615 connected with an output shaft of the first lifting driving part 616 is provided on a top side of the second base 6112, and the first driving wheel 615 and the second driving wheel 612 are in transmission connection through the transmission member 614. In particular embodiments, the driving member 614 may be a toothed belt, and the first and second driving wheels 615, 612 may be respective gears; in other embodiments, a sprocket and chain drive or a gear drive may be used.

As shown in fig. 5 and 12, in the embodiment, the second lifting mechanism further includes a second base body, a second lifting driving component and two sets of rotating support members 626, the second lifting support frame 625 is movably disposed on one side of the second base body, the second lifting driving component is used for driving the second lifting support frame 625 to move up and down relative to the second base body, two parallel tracks 627 (parallel to the conveying direction of the conveying device) are disposed on the second lifting support frame 625 at intervals, the two sets of rotating support members 626 are movably disposed in the two tracks 627 respectively, two sides of the bottom of the second end of the conveying layer 603 are respectively mounted on the two sets of rotating support members 626, and the controller controls the lifting amplitude of the second lifting mechanism 602 by controlling the second lifting driving component. After the scheme is adopted, the right end of the position of the conveying layer 603 generated at the right end when the left end is lifted can be adjusted, the track 627 can realize the regulation of the moving range of the rotary support 627, and the rotary support 627 can play a supporting role when moving. In particular, the rotational support 627 may employ bearings. Other parts of the second lifting mechanism 602 may be implemented with reference to the relevant description of the first lifting mechanism 601.

In addition, based on the foregoing embodiments, two telescopic detection assemblies may be described below in more specific and optimized manners, and as shown, the two telescopic detection assemblies may be respectively disposed on different cutting head assemblies 50, where each of the two telescopic detection assemblies includes a first detection element 521, a second detection element 522, a third detection element 523, a first up-down telescopic member, a second up-down telescopic member 527, a third up-down telescopic member 528, and the like.

The first vertical telescopic member, the second vertical telescopic member 527 and the third vertical telescopic member 528 may be arranged at three positions on the mounting plate 502 of the cutting head assembly in a staggered manner, and the first detecting element 521, the second detecting element 522 and the third detecting element 523 are respectively disposed at telescopic ends of the first vertical telescopic member, the second vertical telescopic member 527 and the third vertical telescopic member 528. In particular, in order to make the plane formed by the three detection points and the axial direction of the silicon rod be approximately perpendicular, the first detection element 521, the second detection element 522 and the third detection element 523 are arranged in such a way that the three detection points are located on the same vertical plane perpendicular to the machining direction (namely, the feeding, conveying and discharging directions corresponding to the whole cutting machine) during operation. In addition, the staggered arrangement means that the telescopic members are staggered in the horizontal direction in the illustrated direction so that the telescopic members can normally extend with the detection elements, interference does not occur, and the silicon rod is normally detected.

In the use process, as shown in fig. 3 and fig. 4, after the conveying device 60 conveys the silicon rod 200 to the lower part of the cutting device (each cutting head assembly 50), two telescopic detection assemblies can be started, so that the corresponding first upper and lower telescopic parts, second upper and lower telescopic parts 527 and third upper and lower telescopic parts 528 respectively extend downwards to a certain distance until the position detection points of the three detection elements can touch the silicon rod, then, by detecting the three detection elements at the three detection positions, three circumscribed position points (corresponding to the detection position points) on one group of identical tangent planes of the silicon rod 200 can be obtained, the corresponding axial center point can be conveniently obtained by the other group of three circumscribed position points, and the connecting line of the two center points represents the current axial direction of the silicon rod, and by comparing the axial direction with the preset accuracy (such as the horizontal direction accuracy or the machining direction accuracy), the inclination of the silicon rod can be easily obtained.

In the specific implementation, each detection element is in communication connection with the controller, and after each group of detection elements obtains the data of two groups of three circumscribed position points, the detection result is transmitted in time. To facilitate placement, assembly, adjustment, maintenance and signal connection, the individual sensing elements may be implemented with probes. In addition, considering that the front face of the cutter head assembly mounting plate (the side containing the respective cutting wheel sets and the looped wires) is more limited in space constraints, also for ease of arrangement, maintenance and adjustment, the telescoping detection assembly or the first, second and third upper and lower telescoping members 527, 526 may be provided on the back face of the mounting plate 502.

On this basis, the positional relationship of the respective components may be further optimized, specifically, the first upper and lower telescopic members may be disposed on the top side of the processing accommodation groove 520 of the mounting plate 502 (extending from the top side thereof up to beyond the top side of the mounting plate), and the second upper and lower telescopic members 527 and the third upper and lower telescopic members 528 may be disposed on both sides of the processing accommodation groove 520 of the mounting plate 502, respectively. Further, the distance between the detection position point of the second detection element and the detection position point of the first detection element may be equal to the distance between the detection position point of the third detection element and the detection point of the first detection element, and the second upper and lower telescopic members 527 and the third upper and lower telescopic members 528 are substantially symmetrical to the lower two sides of the first upper and lower telescopic members.

In addition, in order to further improve each detecting element and adapt to different space constraints, avoid or reduce the influence and interference of other parts, each detecting element may adopt a telescopic manner, as shown in the drawing, the first telescopic detecting component and the second telescopic detecting component each further include a first detecting mount 524, a second detecting mount 525 and a third detecting mount 526, the first detecting mount 524, the second detecting mount 525 and the third detecting mount 526 are respectively provided with telescopic channels for the detecting element to enter and exit, and the first detecting mount 524, the second detecting mount 525 and the third detecting mount 526 are respectively provided at telescopic ends (lower ends in the drawing) of the first upper and lower telescopic parts, the second upper and lower telescopic parts 527 and the third upper and lower telescopic parts 528, and the first detecting element 521, the second detecting element 522 and the third detecting element 523 are respectively arranged in the telescopic channels of the first detecting mount 524, the second detecting mount 525 and the third detecting mount 526 in a telescopic manner. Further, the extending directions of the first detecting element 521, the second detecting element 522 are opposite to the extending direction of the third detecting element 523, and are perpendicular to the extending direction of the first detecting element 521. In particular, each telescopic component may adopt a linear reciprocating element such as an air cylinder or an oil cylinder, and its cylinder barrel may be fixedly mounted at a corresponding position of the mounting plate 502, and the piston rod thereof may extend and retract. In addition, considering that the first telescopic member is above the processing accommodation groove 520, the distance that the first telescopic member extends down to the silicon rod is longer, and the length of the telescopic member used is also longer, and the telescopic member needs to exceed the top side of the mounting plate 502 when in extension arrangement, in order to better arrange the first telescopic member and the subsequent sealing needs, the first telescopic detection assembly and the second telescopic detection assembly can both comprise a mounting box 529 with a bottom provided with an access channel, the mounting box 529 is mounted on the mounting plate 502, the first upper telescopic member and the lower telescopic member are arranged in the mounting box 529, and the telescopic ends of the first upper telescopic member and the second telescopic member can extend down and retract through the access channel.

It should be noted that, in some existing cutting head assemblies, the back surface of the mounting plate 502 of the cutting head assembly 50 is provided with an up-down telescopic component (corresponding to the first up-down telescopic component of the present application), but its function is mainly suitable for cooperating with the supporting device 70, that is, when the supporting device 70 is about to act, the up-down telescopic component stretches down in advance against the silicon rod 200, and when the supporting portion of the supporting device 70 moves up to take over the support of the silicon rod 200 by the output device 60, the up-down telescopic component retracts, and in the present application, the first up-down telescopic component is used to carry the first detecting element 521 to move down to facilitate the first detecting element 521 to contact the silicon rod 200. Or from another perspective, the application may be considered as a new use of the existing component with respect to the use of the first up-down telescoping component.

Further, as shown in connection with fig. 4, the spacing between the cutting head assemblies 50 provided with the retractable detecting elements may not be too small nor too large, for example, the number of cutting head assemblies 50 may be seven, two retractable detecting elements may be provided at the second cutting head assembly and the sixth cutting head assembly, respectively, or two retractable detecting elements may be provided at the third cutting head assembly and the fifth cutting head assembly, respectively. Such a distance is relatively suitable to facilitate a more accurate degree of deflection of the silicon rod calculated based on the detected data.

It should be noted that, in the foregoing embodiments and various implementations, the first lifting support 619 is rotatably supported at the bottom of the first end of the conveying layer 603 of the conveying device 60, the second lifting support 625 is movably supported at the bottom of the second end of the conveying layer 603, but in other embodiments, it is not limited thereto, and other implementations may be used to implement separate lifting and adjusting of the two lifting mechanisms, for example, the first lifting support 619 is movably supported at the bottom of the first end of the conveying layer 603 of the conveying device 60, and the second lifting support 625 is movably supported at the bottom of the second end of the conveying layer 603.
