Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of multi-wire cutting machines, and in particular to a slot alignment tool for a multi-wire cutting machine. Background Art
[0002] The working principle of the multi-wire saw is to bring the abrasive into the processing area of the material to be cut for grinding through the high-speed reciprocating motion of the metal wire, and then cut the material to be cut into hundreds or thousands of thin slices at the same time. The length of the groove wheel of the existing multi-wire saw is usually more than 700mm, and the length of each cutting of the silicon carbide ingot is generally not more than 100mm due to cost and hardness reasons. In the actual use of the multi-wire saw, considering the service life of the coating groove on the groove wheel, the groove wheel will be used in a partitioned manner during cutting, that is, the metal wire is only arranged in the use area of the groove wheel, so as to achieve the purpose of process stability and cost reduction.
[0003] The layout position of the metal wire on two adjacent groove wheels is very critical. In order to avoid angle misalignment when cutting the metal wire, which leads to process disorder and scrapping of the cut wafer, the metal wire needs to be arranged in the corresponding grooves of the two adjacent groove wheels (that is, the position of the groove where the metal wire is located is equal to the distance from the end of the groove wheel). For this reason, the traditional practice is to use a steel ruler to measure the distance between the ends of the two groove wheels and the position to be wired. After the wiring is completed, the number of grooves will be counted from the end of the groove wheel to confirm the accuracy of the wiring. Since the groove pitch on the groove wheel is small (the single groove pitch is generally 1mm), during the measurement process of the steel ruler, a slight tilt will cause the measurement error to be expanded to one or more grooves. In addition, the method of manually counting grooves is time-consuming and labor-intensive, especially when the wiring and outlet positions of the metal wire are far away from the end of the groove wheel, it is very easy to make mistakes.

[0034] The present disclosure provides a groove alignment tool for a multi-wire sawing machine, which is used to align the corresponding grooves on the first groove wheel 10 and the second groove wheel 20 that are arranged in parallel and spaced apart. It should be noted here that the corresponding grooves on the first groove wheel 10 and the second groove wheel 20 refer to the grooves being at equal distances from the ends of the groove wheels where they are located, so that the metal wire can be ensured to operate normally on the multi-wire sawing machine, and the metal wire can be prevented from having an angle error during cutting, resulting in process disorder and scrapping of the cut wafers.
[0035] See also Figure 1 and Figure 2 The groove alignment tool provided by the present invention includes a base 30 and a groove alignment ruler 40. The base 30 is provided with a positioning mechanism for positioning the base 30 to the surface of the first groove wheel 10. The groove alignment ruler 40 is arranged on the base 30, and the groove alignment ruler 40 is arranged to be tangent to the corresponding grooves on the surface of the first groove wheel 10 and the surface of the second groove wheel 20 when the base 30 is positioned to the surface of the first groove wheel 10.
[0036] In the technical solution provided in the present disclosure, a positioning mechanism is provided on the base 30 so that it can be positioned on the surface of the first groove wheel 10, and a groove ruler 40 is provided on the base 30. The groove ruler 40 can be tangent to the corresponding grooves on the surface of the first groove wheel 10 and the surface of the second groove wheel 20 when the base 30 is positioned on the surface of the first groove wheel 10, and then the groove ruler 40 can be used as a reference to lay the metal wire in the corresponding grooves on the first groove wheel 10 and the second groove wheel 20, thereby ensuring the accuracy of the wiring position of the metal wire on the first groove wheel 10 and the second groove wheel 20, and effectively preventing process disturbances and scrapping of cut chips caused by wiring errors.
[0037] In addition, compared with the prior art that uses a steel ruler to measure and confirm the corresponding grooves on the two groove wheels, the groove alignment tool provided by the present invention has the advantages of simple structure and easy use.
[0038] It can be understood that the groove alignment tool provided by the present disclosure uses the groove alignment ruler 40 provided on the base 30 as a reference to ensure that the grooves where the metal wires arranged on the two groove wheels are corresponding, that is, the distance between the position of the groove where the metal wires on the two groove wheels (the first groove wheel 10 and the second groove wheel 20) are located and the end of the groove wheel is equal, so as to ensure that the metal wires will not cause process disorder or scrap the cut wafers due to angle misalignment during operation. In specific operation, the groove alignment tool can be positioned on the surface of the first groove wheel 10 by the positioning mechanism provided on the base 30, and then the groove alignment ruler 40 that can extend from the first groove wheel 10 to the second groove wheel 20 is used as a reference, and the thin wires with heavy objects tied at both ends are placed in the grooves of the two groove wheels, and the groove alignment ruler 40 is used as a reference to make the thin wires on the two groove wheels fall into the grooves adjacent to one or more groove spacings of the groove alignment ruler 40, and then the groove alignment tool is removed, and the metal wires are arranged using the thin wires as a mark. Through this method, only one person can achieve accurate arrangement of metal wires.
[0039] It should be noted that in the present disclosure, the definitions of the first sheave 10 and the second sheave 20 are only for convenience of description. In actual operation, the groove alignment tool can be positioned on the surface of the second sheave 20 by the positioning mechanism provided on the base 30, and then the groove alignment ruler 40 is extended from the second sheave 20 to the surface of the first sheave 10, thereby providing a reference basis for the wiring of the metal wire and ensuring accurate wiring.
[0040] In the present disclosure, the role of the positioning mechanism is to position the base 30 on the surface of the first groove wheel 10. In some embodiments, the positioning mechanism is combined with Figure 3 As shown, the positioning mechanism includes a concave arc surface 31 provided on the base 30, and a plurality of convex ridges 311 are provided on the concave arc surface 31. The plurality of convex ridges 311 are arranged at intervals and can mesh with the grooves on the first sheave 10. In the present disclosure, the positioning of the base 30 is achieved by providing the convex ridges 311 to cooperate with the original groove structure on the first sheave 10. The structure is simple and easy to use. When used, the concave arc surface 31 provided with the plurality of convex ridges 311 is placed against the first sheave 10, so that the plurality of convex ridges 311 mesh with the grooves on the first sheave 10, and the positioning of the base 30 can be easily achieved.
[0041] In some embodiments, the spacing between two adjacent ridges 311 is a multiple of the width of the groove on the first sheave 10. It is understandable that by controlling the spacing between two adjacent ridges 311 to be a multiple of the width of the groove on the first sheave 10, not only can the meshing requirements of the ridges 311 and the grooves, that is, the positioning requirements, be met, but also the manufacturing difficulty of the positioning mechanism can be reduced.
[0042] In some embodiments, in combination Figure 4As shown, a positioning portion 32 is provided on the base 30, and the positioning mechanism is provided on the positioning portion 32. It can be understood that by providing the positioning mechanism on the positioning portion 32, it is convenient to select the material of the positioning portion 32, so as to achieve the purpose of easy processing of the positioning mechanism and reducing costs.
[0043] In some embodiments, the positioning part 32 is detachably fixed to the base 30. The above arrangement enables the operator to replace the positioning part 32 with the corresponding positioning mechanism according to the different groove spacings on the sheave, that is, by setting the positioning part 32 to be replaceable, the applicability of the pair of groove tooling is improved. Figure 4 As shown, a slot 321 is provided at the bottom of the positioning portion 32 for being snapped onto the base 30 , and a bolt hole is provided at the side of the positioning portion 32 for bolts or screws to lock and fix the positioning portion 32 onto the base 30 .
[0044] In some embodiments, the groove ruler 40 is configured to be retractable along its length. It is understandable that by configuring the groove ruler 40 to be retractable along its length, the alignment operation of the grooves on two sheaves with different spacings can be satisfied, that is, the applicability of the groove tooling is improved. At the same time, the retractable structure of the groove ruler 40 can also be conveniently stored.
[0045] In some embodiments, the groove ruler 40 is provided with a scale for measuring the distance between the grooves and the respective ends of the first sheave 10 and the second sheave 20. After the wiring is completed, the distance between the groove where the metal wire is located and the corresponding sheave end is measured by the groove ruler 40 with a scale to confirm whether the wiring position of the metal wire is accurate.
[0046] In some embodiments, the groove ruler 40 is rotatably disposed at one end of the base 30 and can rotate between a first position and a second position, wherein in the first position, the groove ruler 40 is parallel to the base 30; in the second position, the groove ruler 40 forms an angle with the base 30 so that the groove ruler 40 can be placed on the surface of the second groove wheel 20 when the base 30 is positioned on the surface of the first groove wheel 10. It can be understood that when not in use, the groove ruler 40 is rotated to the first position parallel to the base 30, that is, the groove ruler 40 is stored.
[0047] In some embodiments, in order to better accommodate the slot ruler 40, Figure 5 As shown, the base 30 is provided with an open slot 33 extending along the length direction thereof for receiving the slot ruler 40 . When in the first position, the slot ruler 40 is received in the open slot 33 .
[0048] In some embodiments, a fixing member is further provided on the base 30, and the fixing member is used to fix the slot ruler 40 when the slot ruler 40 is received in the opening slot 33. In some embodiments, the fixing member is a strap 34 provided at one end of the base 30 away from the slot ruler 40, and when the slot ruler 40 rotates relative to the base 30 and is received in the opening slot 33, the strap 34 constrains the slot ruler 40 in the opening slot 33 to achieve the reception.
[0049] So far, various embodiments of the present disclosure have been described in detail. In order to avoid obscuring the concept of the present disclosure, some details known in the art are not described. Based on the above description, those skilled in the art can fully understand how to implement the technical solution disclosed here.
