Description

[0002] At present, both slicers and squarers usually use cutting wires for slicing or squaring. Usually, the cutting wire is wound on a cutting wheel, and the cutting wire can be driven to move by the rotation of the cutting wheel to complete the cutting action. In practical applications, before the cutting wire enters the cutting wheel, it is usually necessary to set a guide wheel to adjust the direction of the cutting wire so that the cutting wire can enter the cutting wheel in a state perpendicular to and tangent to the cutting wheel to avoid the defect of the cutting wire being broken.

[0003] However, due to the long distance between the guide wheel and the cutting wheel, the cutting line will be exposed for a long distance between the guide wheel and the cutting wheel, and the cutting line is easily broken by external impact. Moreover, in the existing technology, whether the cutting line is perpendicular to the cutting wheel is determined only by visual inspection or steel ruler measurement. Due to the lack of a reliable positioning reference when measuring with a steel ruler, the measurement error is large, and the cutting line is easily inclined relative to the cutting wheel. The cutting wheel is further increased. The risk of breaking the cutting line. Utility Model Content

[0048] An embodiment of the present application provides a protective structure for a cutting wire, which can be used for silicon material cutting. The silicon material cutting equipment may include but is not limited to slicers, square cutters and other equipment that require the use of cutting wires for cutting operations. The embodiment of the present application may not limit the specific type of the silicon material cutting equipment.

[0049] Reference Figure 1 , shows a schematic diagram of an application scenario of a cutting line protection structure according to an embodiment of the present application, referring to Figure 2 , showing Figure 1 The structural diagram of the protective structure shown in FIG. Figure 3 , showing Figure 2 The schematic diagram of the top view of the protective structure shown; refer to Figure 4 , showing Figure 2 A schematic diagram of the top view of the protective structure shown;

[0050] like Figure 1As shown, the protective structure can be used in a silicon material cutting device, and the silicon material cutting device can include a frame 10, a guide wheel 11, a cutting wheel 12, and a cutting line 13; wherein the guide wheel 11 and the cutting wheel 12 are both connected to the frame 10; and the cutting line 13 is respectively wound around the guide wheel 11 and the cutting wheel 12. In practical applications, before the cutting line 13 enters the cutting wheel 12, it is usually necessary to set the guide wheel 11 to adjust the direction of the cutting line 13, so that the cutting line 13 can enter the cutting wheel 12 in a state perpendicular to and tangent to the cutting wheel 12, so as to avoid the defect of the cutting line 13 being broken.

[0051] like Figure 1 and Figure 2 As shown, the protective structure may specifically include: a protective structure body 14, which may be disposed between the guide wheel 11 and the cutting wheel 12 and at least partially shield the cutting line 13; and a measuring mechanism 15, which is disposed on the protective structure body 14 and may be used to measure the position of the cutting line 13.

[0052] In the embodiment of the present application, the protective structure body 14 of the protective structure can be arranged between the guide wheel 11 and the cutting wheel 12, and at least partially shield the cutting line 13 to protect the cutting line 13 and avoid the cutting line 13 from being broken. Moreover, since the protective structure body 14 is provided with a measuring mechanism 15, the measuring mechanism 15 can be used to accurately measure the position of the cutting line 13, so that the cutting line 13 can enter the cutting wheel 12 in a state perpendicular to and tangent to the cutting wheel 12, further avoiding the defect of the cutting line 13 being broken.

[0053] In a specific application, the protective structure body 14 can shield the cutting line 13 from the side of the cutting line 13 to prevent the cutting line 13 from being hit from the side and causing the defect of breaking. The protective structure body 14 can be arranged along the extension direction of the cutting line 13 to shield the cutting line 13 as long as possible and improve the protection effect for the cutting line 13. In practical applications, the length of the protective structure body 14 can be greater than or equal to three quarters of the distance between the cutting wheel 12 and the guide wheel 11 to protect the cutting line 13 exposed between the cutting wheel 12 and the guide wheel 11.

[0054] For example, when the length of the cutting line 13 exposed between the cutting wheel 12 and the guide wheel 11 is 100 centimeters, the length of the protective structure body 14 may be greater than or equal to 75 centimeters.

[0055] Specifically, the measuring mechanism 15 provided on the protective structure body 14 can be used to measure the position of the cutting line 13 to determine whether the cutting line 13 can enter the cutting wheel 12 in a state perpendicular to the axial direction of the cutting wheel 12, thereby avoiding the problem of inaccurate measurement caused by the operator manually measuring the position of the cutting line 13. In practical applications, when the measuring mechanism 15 measures that the position of the cutting line 13 does not meet the requirements, the position of the guide wheel 11 can be adjusted to adjust the position of the cutting line 13 until the cutting line 13 can enter the cutting wheel 12 in a correct state, thereby avoiding the defects of increased wear or breakage of the cutting line 13 after entering the cutting wheel 12.

[0056] Optionally, the measuring mechanism 15 may include: at least one of a laser measuring instrument, an angle measuring instrument, a collimator, and a ruler. The embodiment of the present application does not specifically limit the type of the measuring mechanism 15.

[0057] In the embodiment of the present application, the protective structure body 14 can be detachably connected to the frame 10 by fastener connection, snap connection, etc., that is, when the cutting line 13 needs to be protected, the protective structure body 14 can be installed on the frame 10 to protect the cutting line 13 through the protective structure body 14, and the position of the cutting line 13 can be accurately measured by the measuring mechanism 15 on the protective structure body 14. When there is no need to protect the cutting line 13 or the protective structure needs to be repaired and maintained, the protective structure body 14 can be removed from the frame 10 to improve the maintainability of the protective structure.

[0058] like Figure 2 , Figure 3 As shown, the protective structure body 14 is provided with a groove 141, and the groove 141 can be used to accommodate the cutting line 13; wherein the measuring mechanism 15 is a plurality of scales arranged on the groove 141, and the plurality of scales are arranged at intervals along the extension direction of the cutting line 13, and the measuring direction of the scales is perpendicular to the extension direction of the cutting line 13. In a specific application, the groove 141 can be arranged along the vertical direction (i.e., the direction perpendicular to the axial direction of the cutting wheel 12), and the measuring direction of the scale can be the horizontal direction.

[0059] In practical applications, the scale can be used to measure the position of the cutting line 13. By arranging multiple scales at intervals along the extension direction of the cutting line 13, the position of the cutting line 13 can be measured from multiple positions. When the positions of the cutting line 13 measured on multiple scales are the same, it can be considered that the extension direction of the cutting line 13 is the vertical direction, that is, the cutting line 13 can enter the cutting wheel 12 in a state perpendicular to the axial direction of the cutting wheel 12, and the position of the cutting line 13 can meet the requirements. When the positions of the cutting line 13 measured on multiple scales are different, it can be considered that the extension direction of the cutting line 13 is inclined relative to the vertical direction, that is, the cutting line 13 cannot enter the cutting wheel 12 in a state perpendicular to the axial direction of the cutting wheel 12, and the position of the cutting line 13 cannot meet the requirements.

[0060] In a specific application, the horizontal width of the groove 141 can be set according to the actual situation. For example, the width of the groove 141 can be 8 mm, 10 mm or 12 mm. Correspondingly, the measurement range of the scale needs to cover the width of the entire groove 141, but the minimum scale of the scale can be set according to the actual situation. For example, the minimum scale of the scale can be 0.5 mm, 1 mm or 2 mm, etc., which is not specifically limited in the embodiment of the present application.

[0061] Optionally, in order to improve the measurement accuracy, the spacing between the multiple scales along the vertical direction needs to be greater than or equal to 100 mm. In practical applications, when the distance between the scales is less than 100 mm, since the distance between the scales is too close, when the inclination of the cutting line 13 is small, the positions of the cutting line 13 measured by the two scales that are too close are relatively close, and the inclination of the cutting line 13 may not be detected, thereby reducing the measurement accuracy of the entire measuring mechanism 15.

[0062] For example, the distance between the two scales may be 100 mm, 110 mm, 118 mm or 150 mm, etc., which is not specifically limited in the embodiments of the present application.

[0063] It should be noted that the drawings of the embodiments of the present application only show the case where the number of the scales is two, and in actual applications, the number of the scales can be set according to actual conditions. For example, the number of the scales can also be 3, 4, or 6, etc., and the embodiments of the present application do not specifically limit this.

[0064] like Figure 1 , Figure 2 As shown, the scale can be set at the bottom of the groove 141. In this way, when the cutting line 13 passes through the groove 141, the position information of the cutting line 13 can be directly read from the scale at the bottom of the groove 141.

[0065] In a specific application, the scale can be set in the groove 141 by directly drawing scales on the bottom of the groove 141. The implementation method is relatively simple and the measurement accuracy is relatively high.

[0066] Reference Figure 5 , shows a schematic diagram of an application scenario of another cutting line protection structure described in an embodiment of the present application, referring to Figure 6 , showing Figure 5 The structural diagram of the protective structure shown in FIG. Figure 7 , showing Figure 6 The schematic diagram of the top view of the protective structure shown in FIG. Figure 8 , showing Figure 6 The side view of the protective structure is shown in FIG. Figures 5 to 7 As shown, the scale is movably connected to the protective structure body 14, and when the scale needs to measure the position of the cutting line 13, the scale is located above the groove 141 to facilitate the operator to directly read the position information of the cutting line 13, thereby improving the convenience of the operator in reading.

[0067] In a specific application, when the cutting line 13 needs to be placed in the groove 141, the scale can be moved to remove the shielding of the scale from the groove 141, so as to facilitate placing the cutting line 13 in the groove 141. After the cutting line 13 is placed in the groove 141, the scale can be moved above the groove 141, so that the scale can measure the position of the cutting line 13 in the groove 141.

[0068] Optionally, the scale may be movably connected to the protective structure body 14 by rotation, sliding, etc. The embodiment of the present application does not specifically limit the connection method of the scale to the protective structure body 14.

[0069] In some optional embodiments of the present application, a block is provided at one end of the protective structure body 14 close to the cutting wheel 12, and the block at least partially blocks the groove 141, and a through hole is provided on the block for the cutting line 13 to pass through. The block can be used to prevent a large amount of cutting fluid from entering the groove 141 and causing damage to the groove 141 and the scale, thereby increasing the service life of the protective structure.

[0070] Reference Fig. 9 , shows a schematic diagram of an application scenario of another cutting line protection structure described in an embodiment of the present application, referring to Fig.10 , showing Fig. 9 The structural diagram of the protective structure shown in FIG. Fig.11 , showing Fig.10 The schematic diagram of the top view of the protective structure shown in FIG. Fig.12, showing Fig.10 The side view of the protective structure is shown in FIG. Figures 9 to 12 As shown, the protective structure body 14 may specifically include: a baffle 142 arranged along the extension direction of the cutting line 13, the two baffles 142 are arranged at intervals, and a gap 143 for the cutting line 13 to pass through is formed between the two baffles 142; the measuring mechanism 15 may include a plurality of scales, the plurality of scales are arranged at intervals along the extension direction of the cutting line 13, and the measuring direction of the scales is perpendicular to the extension direction of the cutting line 13.

[0071] In a specific application, the baffle 142 can be used to protect the cutting line 13 from the side of the cutting line 13 to prevent the cutting line 13 from being hit from the side. In practical applications, the baffle 142 is used to protect the cutting line 13 from the side, which is conducive to the flexibility of the layout.

[0072] In practical applications, the baffle 142 can be detachably connected to the frame 10, and the height of the baffle 142 can be slightly higher than the cutting line 13 to achieve side protection for the cutting line 13. The width of the gap 143 between the two baffles 142 can refer to the width of the groove 141 in the above embodiment, and the setting method of the scale can refer to the setting method of the scale in the above embodiment, which will not be repeated here.

[0073] like Fig. 9 As shown, the two baffles 142 have the same length along the extending direction of the cutting line 13, so as to protect the cutting line 13 as a whole from both sides of the cutting line 13 to prevent the cutting line 13 from being hit by both sides.

[0074] Reference Fig.13 , shows a schematic diagram of an application scenario of another cutting line protection structure described in an embodiment of the present application, referring to Fig.14 , showing Fig.13 The structural diagram of the protective structure shown in FIG. Fig.15 , showing Fig.14 The schematic diagram of the top view of the protective structure shown in FIG. Fig.16 , showing Fig.14 The side view of the protective structure is shown in FIG. Figures 13 to 16 As shown, the lengths of the two baffles 142 along the extending direction of the cutting line 13 are different, and the length of the baffle 142 on the left side of the cutting line 13 is obviously shorter than the length of the baffle 142 on the right side. In actual applications, the impact on the cutting line 13 mainly comes from the side away from the cutting chamber (i.e. Fig.13 Therefore, only the side away from the cutting chamber needs to be protected as a whole. In this way, the cutting line 13 can be prevented from being impacted by the outside world and the material of the baffle plate 142 can be saved.

[0075] like Figures 13 to 16 As shown, the protective structure body 14 may further include a connecting plate 144 , and the connecting plate 144 is respectively connected to the two baffles 142 to achieve a reliable connection between the two baffles 142 .

[0076] It should be noted that Figures 13 to 16 Only the case where the connecting plate 144 is arranged on the top of the baffle 142 is shown in the figure. In actual application, the position of the connecting plate 144 can be set according to actual conditions. For example, the position of the connecting plate 144 can also be set at the bottom or middle area of ​​the baffle 142, etc. The embodiment of the present application does not specifically limit the setting position of the connecting plate 144.

[0077] In some optional embodiments of the present application, the scale is movably connected to the baffle 142 and / or the connecting plate, and when the scale needs to measure the position of the cutting line 13, the scale is located above the gap 143 to facilitate the operator to directly read the position information of the cutting line 13, thereby improving the convenience of the operator's reading.

[0078] In a specific application, when the cutting line 13 needs to be placed in the gap 143, the scale can be moved to remove the shielding of the scale from the gap 143, so as to facilitate the placement of the cutting line 13 in the gap 143. After the cutting line 13 is placed in the gap 143, the scale can be moved above the gap 143, so that the scale can measure the position of the cutting line 13 in the gap 143.

[0079] Optionally, the scale may be movably connected to the baffle 142 or the connecting plate 144 by rotation, sliding, etc. The embodiment of the present application does not specifically limit the connection method of the scale to the protective structure body 14.

[0080] In summary, the cutting line protection structure described in the embodiment of the present application can at least include the following advantages:

[0081] In the embodiment of the present application, the protective structure body of the protective structure can be arranged between the guide wheel and the cutting wheel, and at least partially shield the cutting line to protect the cutting line and avoid the cutting line from being broken. Moreover, since a measuring mechanism is arranged on the protective structure body, the measuring mechanism can be used to accurately measure the position of the cutting line, so that the cutting line can enter the cutting wheel in a state perpendicular to and tangent to the cutting wheel, further avoiding the defect of the cutting line being broken.
