[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] The crystal rod deviation detection device 1 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0026] like Figure 1 and Figure 2As shown, the crystal rod deviation detection device 1 according to the embodiment of the utility model includes a base (not shown in the figure) and two detection components 10.

[0027] Two detection components 10 are arranged at intervals on the base, and each detection component 10 includes a bracket 300, a crystal tray distance sensor 200 and a crystal rod distance sensor 100. The crystal tray distance sensor 200 and the crystal rod distance sensor 100 are both arranged on the bracket 300, and the crystal rod distance sensor 100 is located above the crystal tray distance sensor 200 (the up and down directions are shown by the arrows in the figure).

[0028] Specifically, the crystal ingot distance measuring sensor 100 detects the distance between itself and the crystal ingot 2 , and the crystal tray distance measuring sensor 200 detects the distance between itself and the crystal tray 3 .

[0029] For example, the two detection components 10 are respectively the first detection component and the second detection component. During detection, the crystal rod distance sensor 100 of the first detection component detects the first crystal rod distance X1 between the crystal rod 2, and the crystal tray distance sensor 200 detects the first crystal tray distance X2 between the crystal tray 3. By calculating the difference Z1 between the first crystal rod distance X1 and the first crystal tray distance X2, the relative distance between the edges of the crystal rod 2 and the crystal tray 3 at the first detection component can be obtained. The crystal rod distance sensor 100 of the second detection component detects the second crystal rod distance Y1 between the crystal rod 2, and the crystal tray distance sensor 200 detects the second crystal tray distance Y2 between the crystal tray 3. By calculating the difference Z2 between the second crystal rod distance Y1 and the second crystal tray distance Y2, the relative distance between the edges of the crystal rod 2 and the crystal tray 3 at the second detection component can be obtained.

[0030] By judging the values ​​of Z1 and Z2, the degree of deviation of the crystal rod 2 and the crystal tray 3 can be determined. When any value of Z1 and Z2 exceeds the allowable range, it means that the deviation of the crystal rod 2 on the crystal tray 3 is greater than the allowable range and a collision may occur. At this time, an alarm is used to inform the operator to adjust the position of the crystal rod 2.

[0031] In addition, by calculating the difference between Z1 and Z2, the difference between the relative distance between the crystal rod 2 and the crystal tray 3 at the first detection component and the relative distance between the edges of the crystal rod 2 and the crystal tray 3 at the second detection component can be reflected, thereby reflecting the relative inclination of the crystal rod 2 and the crystal tray 3. When the difference between Z1 and Z2 exceeds the allowable range, it means that the inclination of the crystal rod 2 on the crystal tray 3 is greater than the allowable range, and a collision may occur. At this time, an alarm is issued to inform the operator to adjust the position of the crystal rod 2.

[0032] In this way, not only the degree of parallel deviation of the crystal ingot 2 but also the degree of inclination of the crystal ingot 2 can be detected.

[0033] Those skilled in the art can determine the allowable ranges of Z1 and Z2 and the allowable range of the difference between Z1 and Z2 according to actual needs and the actual conditions of subsequent slicing equipment.

[0034] According to the crystal rod displacement detection device 1 of the embodiment of the utility model, by setting two detection components 10 spaced apart from each other, and the two detection components 10 both include a crystal tray distance sensor 200 and a crystal rod distance sensor 100, the displacement of the crystal rod 2 and the crystal tray 3 at the two detection components 10 can be detected respectively, so as to reflect the relative displacement degree of the crystal rod 2 and the crystal tray 3. Compared with the method of visual judgment by detection personnel in the related art, on the one hand, the detection speed is faster and the detection efficiency is higher, which can reduce the waiting time required for detection. On the other hand, manpower can be saved and the degree of automation of the production line can be improved. On the other hand, the detection by distance sensor is more accurate than visual inspection, which can avoid misjudgment caused by visual errors and avoid collision of crystal rods.

[0035] Therefore, the crystal rod deviation detection device 1 according to the embodiment of the utility model has the advantages of high detection efficiency, high degree of automation, good accuracy, etc.

[0036] The following describes a crystal rod deviation detection device 1 according to a specific embodiment of the present invention with reference to the accompanying drawings.

[0037] In some specific embodiments of the present invention, Figure 1 and Figure 2 As shown, the crystal rod deviation detection device 1 according to the embodiment of the utility model includes a base and two detection components 10.

[0038] Specifically, Figure 1 and Figure 2 As shown, the support 300 includes a support substrate, a support rod 330, an upper mounting plate 310 and a lower mounting plate 320, the crystal support distance sensor 200 is mounted on the lower mounting plate 320, the crystal ingot distance sensor 100 is mounted on the upper mounting plate 310, the upper mounting plate 310 and the lower mounting plate 320 are both arranged on the support rod 330 and the upper mounting plate 310 is located above the lower mounting plate 320, the support rod 330 is arranged on the support substrate, and the support substrate is arranged on the base. In this way, the crystal ingot distance sensor 100 and the crystal support distance sensor 200 can be arranged at intervals up and down.

[0039] Advantageously, if Figure 1 and Figure 2As shown, the support base plate includes a lifting adjustment plate 350 and a horizontal adjustment plate 340. The lifting adjustment plate 350 can be lifted and lowered on the base, the horizontal adjustment plate 340 can be horizontally moved on the lifting adjustment plate 350, and the support rod 330 is arranged on the horizontal adjustment plate 340. In this way, the position adjustment of the crystal ingot distance sensor 100 and the crystal tray distance sensor 200 in the horizontal and vertical directions can be achieved through the lifting adjustment plate 350 and the horizontal adjustment plate 340, so that the crystal ingot distance sensor 100 and the crystal tray distance sensor 200 are easy to align with the crystal ingot 2 and the crystal tray 3.

[0040] More specifically, Figure 1 and Figure 2 As shown, the lifting and adjusting plate 350 is provided with a vertical oblong hole 351 whose length direction is oriented in the vertical direction. The lifting and adjusting plate 350 is lifted and lowered on the base by means of a threaded fastener engaged in the vertical oblong hole 351. The lifting and adjusting plate 350 is also provided with a horizontal oblong hole 341 whose length direction is oriented in the horizontal direction. The horizontal adjusting plate 340 is horizontally movable on the lifting and adjusting plate 350 by means of a threaded fastener engaged in the horizontal oblong hole 341. Specifically, the lifting and adjusting plate 350 includes a horizontal section and a vertical section. The horizontal oblong hole 341 is provided on the horizontal section, and the vertical oblong hole 351 is provided on the vertical section. In this way, the threaded fastener can be loosened to allow the threaded fastener to slide in the vertical oblong hole 351 and the horizontal oblong hole 341. The lifting and adjusting plate 350 and the horizontal adjusting plate 340 can be positioned by tightening the threaded fastener, thereby achieving position adjustment of the crystal ingot distance sensor 100 and the crystal support distance sensor 200.

[0041] Alternatively, if Figure 1 As shown, the moving direction of the horizontal adjustment plate 340 is perpendicular to the spacing direction of the two detection components 10. In this way, the basic distance between the crystal ingot distance sensor 100 and the crystal tray distance sensor 200 and the crystal ingot 2 and the crystal tray 3 can be adjusted, so as to measure the distance between the crystal ingot 2 and the crystal tray 3 and judge the degree of deviation.

[0042] More advantageously, if Figure 1 As shown, the spacing direction of the two detection components 10 is oriented along the length direction of the crystal tray 3. Since the crystal tray 3 is arranged on the conveying device and its position is relatively stable, the relative deviation between the crystal rod 2 and the crystal tray 3 is mainly caused by the deviation of the crystal rod 2 itself. By arranging the two detection components 10 with the length direction of the crystal tray 3 as the reference spacing, the deviation of the crystal rod 2 can be easily detected.

[0043] In some examples, the upper mounting plate 310 and the lower mounting plate 320 are movably disposed on the support rod 330. In this way, the position height of the crystal ingot distance sensor 100 and the crystal tray distance sensor 200 can be adjusted, and the distance between the crystal ingot distance sensor 100 and the crystal tray distance sensor 200 can be adjusted, so that the crystal ingot distance sensor 100 and the crystal tray distance sensor 200 can be aligned with the crystal ingot 2 and the crystal tray 3.

[0044] Specifically, the support rod 330 has a thread, and the thread on the support rod 330 is matched with a first upper nut, a second upper nut, a first lower nut, and a second lower nut, the upper mounting plate 310 is clamped between the first upper nut and the second upper nut, and the lower mounting plate 320 is clamped between the first lower nut and the second lower nut. In this way, the position height of the upper mounting plate 310 and the lower mounting plate 320 can be adjusted by the matching of the nut and the thread on the support rod 330.

[0045] Optionally, both the crystal tray distance measuring sensor 200 and the crystal rod distance measuring sensor 100 are laser distance measuring sensors, which can ensure the detection efficiency and detection accuracy of the crystal rod distance measuring sensor 100 and the crystal tray distance measuring sensor 200.

[0046] Furthermore, the distance between the two detection components 10 is 700-850 mm, which can reduce the detection error, improve the detection accuracy, and make the crystal rod deviation detection device 1 applicable to crystal rods 2 of different lengths.

[0047] Reference below Figure 1 and Figure 2 The working process of the crystal rod deviation detection device 1 according to the embodiment of the utility model is described.

[0048] Adjust the bracket 300 so that the crystal tray distance sensor 200 is aligned with the crystal tray 3, and the crystal rod distance sensor 100 is aligned with the crystal rod 2. Then adjust the horizontal adjustment plate 340 of the bracket 300 to adjust the calibration distance, and finally input the allowable range of Z1, Z2 and the difference between Z1 and Z2 in the human-computer interaction interface.

[0049] When the manipulator grabs the crystal rod 2 onto the crystal tray 3, the crystal rod distance sensor 100 and the crystal tray distance sensor 200 of one detection component 10 respectively measure the distances X1 and X2 to the crystal rod 2 and the crystal tray 3, and calculate the difference between X1 and X2 as Z1. The crystal rod distance sensor 100 and the crystal tray distance sensor 200 of another detection component 10 respectively measure the distances Y1 and Y2 to the crystal rod 2 and the crystal tray 3, and calculate the difference between Y1 and Y2 as Z2.

[0050] Determine whether Z1, Z2 and the difference between Z1 and Z2 are within the allowable range. If Z1, Z2 and the difference between Z1 and Z2 are all within the allowable range, it proves that the deviation of crystal rod 2 is small and does not affect subsequent production. If any of Z1, Z2 and the difference between Z1 and Z2 is outside the allowable range, it proves that the deviation of crystal rod 2 is large, and an alarm is issued at this time, and the position of the crystal rod is adjusted manually.

[0051] Other structures and operations of the crystal rod deviation detection device 1 according to the embodiment of the utility model are known to ordinary technicians in the field and will not be described in detail here.
