[0002] Multi-wire cutting is a cutting method that uses high-speed reciprocating motion of metal wires to bring abrasives into the processing area of ​​the workpiece to be cut for grinding, and cuts hard and brittle materials into hundreds of thin slices at a time. Multi-wire cutting is implemented on a wire saw. Taking diamond wire cutting of silicon rods as an example, when the wire saw is running, the silicon rod is fed from top to bottom, and the wire net composed of diamond wires cuts the silicon rod into multiple slices during high-speed rotation.

[0003] While cutting, cutting fluid needs to be sprayed on the cutting part to remove the heat and debris generated during the cutting process, and the debris in the cutting fluid is collected through the debris box under the cutting piece. However, in the prior art, as the cutting depth increases, the diamond wire will have a wire bow, resulting in insufficient liquid on one side of the diamond wire. At this time, only by spraying the cutting fluid, it is impossible to ensure that the cutting fluid enters between the silicon wafers normally, so that the cutting fluid cannot play a normal cooling, chip removal and lubrication role. At the same time, with the advancement of thinning and thinning, the diamond wire's ability to carry liquid will become worse and worse, further leading to reduced cutting efficiency and increased costs.

For example, the cross-section of the mounting block is set to a sector or a circle. In addition, although the present embodiment is introduced in conjunction with diamond wire cutting of silicon rods, this is not intended to limit the scope of protection of the present application. Without departing from the principles of the present application, those skilled in the art can apply the present application to other application scenarios. For example, by cutting sapphire with diamond wire, etc., of course, the fragment box of the present application can be used for other equipment that needs to be connected to liquids, such as mortar machines or sawing machines.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. In addition, in the description of the present application, "multiple" refers to at least two.

[0040] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" 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 direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0041] As described in the background technology, multi-wire cutting is a cutting method that uses high-speed reciprocating motion of metal wires to bring abrasives into the processing area of ​​the workpiece to be cut for grinding, and simultaneously cuts hard and brittle materials into hundreds of thin slices. Multi-wire cutting is implemented on a wire cutting machine. Taking diamond wire cutting of silicon rods as an example, when the wire cutting machine is running, the silicon rod is fed from top to bottom, and the wire net composed of diamond wires cuts the silicon rod into multiple slices during high-speed rotation.

[0042] While cutting, cutting fluid needs to be sprayed on the cutting part to remove the heat and debris generated during the cutting process, and the debris in the cutting fluid is collected through the debris box under the cutting piece. However, in the prior art, as the cutting depth increases, the diamond wire will have a wire bow, resulting in insufficient liquid on one side of the diamond wire. At this time, only by spraying the cutting fluid, it is impossible to ensure that the cutting fluid enters between the silicon wafers normally, so that the cutting fluid cannot play a normal cooling, chip removal and lubrication role. At the same time, with the advancement of thinning and thinning, the diamond wire's ability to carry liquid will become worse and worse, further leading to reduced cutting efficiency and increased costs.

[0043] In order to solve the problems of low cutting efficiency and high cost caused by the difficulty of diamond wire carrying liquid in the existing cutting process, the present application provides a fragmentation box and a wire cutting machine, the fragmentation box includes a main body and a guide device, the main body is formed with a accommodating cavity with an open top for accommodating cutting liquid, an adapter is provided at the bottom of the main body, the guide device includes a guide box body and a flow regulating member, a liquid inlet and a liquid outlet are provided on the guide box body, a guide channel is formed between the liquid inlet and the liquid outlet, the liquid inlet is connected to the adapter, and the liquid outlet is connected to the flow regulating member.

[0044] When the above technical solution is adopted, the liquid level of the cutting liquid in the accommodating chamber can be adjusted by the flow regulating member, so that the cut part can be cut by immersion cutting, which improves the liquid carrying capacity of the diamond wire and thus improves the cutting efficiency. After the cutting is completed, the cutting tool can be withdrawn by immersion, which improves the problem of wire breakage caused by silicon wafer clamping, thereby reducing costs.

[0045] Refer to the following Figures 1 to 5 , the fragment box of the present application is described in detail. Among them, Figure 1 The overall structure diagram of the debris box of the present application; Figure 2 A structural diagram of the main body of the debris box of the present application; Figure 3 A structural diagram of a support device for a debris box of the present application; Figure 4 This is a structural diagram of the flow guide device of the present application; Figure 5 This is a schematic diagram of the connection between the main body and the guide device of the present application.

[0046] like Figures 1 to 3 As shown, in a preferred embodiment, the debris box includes a main body 10 and a guide device 20, the main body 10 is formed with a accommodating chamber 11 with an open top for accommodating cutting fluid, handles 13 and mounting blocks 14 are provided on both sides of the length direction of the main body 10, and the two mounting blocks 14 are both located in the middle of the side of the main body 10, the main body 10 is fixed by plugging the mounting blocks 14 with support devices 30 installed on two oppositely arranged side walls of the wire cutting machine, and two sets of adapters 12 are symmetrically provided at the bottom of the main body 10.

[0047] like Figure 4 and Figure 5 As shown, the flow guide device 20 includes a flow guide box body 21, a flow regulating member 22 and a sealing assembly 23, wherein the flow guide box body 21 is provided with two liquid inlets 211 and two liquid outlets, a flow guide channel is formed between the liquid inlet 211 and the liquid outlet on each side, the liquid inlet 211 is used to connect with the adapter 12, and the liquid outlet is connected with the flow regulating member 22, and the sealing assembly 23 can seal the adapter 12 and the liquid inlet 211.

[0048] The sealing assembly 23 includes a sealing gasket 231, a pressing block 232 and a connecting piece 233. The sealing gasket 231 is located on the upper side of the liquid inlet 211, the pressing block 232 is located on the upper side of the sealing gasket 231, a first connecting hole is provided on the flow guide box body 21, a second connecting hole is provided on the sealing gasket 231, a third connecting hole is provided on the pressing block 232, and the connecting piece 233 passes through the third connecting hole, the second connecting hole and the first connecting hole in sequence, that is, the connecting piece 233 passes through the pressing block 232, the sealing gasket 231 and the flow guide box body 21 in sequence, so as to fix the sealing assembly 23 and the flow guide box body 21. When the body 10 is connected to the flow guide device 20, the adapter 12 is inserted into the liquid inlet 211, and the sealing gasket 231 is sleeved on the outer side of the adapter 12 to achieve sealing. In this embodiment, the sealing gasket 231 is made of an elastic material such as rubber, the outer diameter of the adapter 12 gradually decreases in the direction toward the guide box body 21, and the inner ring diameter of the sealing gasket 231 is smaller than the outer ring diameter of the adapter 12, and the connecting piece 233 is configured as a screw, and the screw passes through the pressure block 232, the sealing gasket 231 and the guide box body 21 in sequence to complete the fixation of the sealing assembly 23 and the guide box body 21. After the adapter 12 is inserted into the liquid inlet 211 on the guide box body 21, the sealing gasket 231 and the pressure block 232 are both sleeved on the outside of the adapter 12, and because the inner ring diameter of the sealing gasket 231 is smaller than the outer ring diameter of the adapter 12, the sealing gasket 231 will be deformed so that the sealing gasket 231 is tightly combined with the adapter 12, thereby ensuring the tightness of the seal at the connection between the main body 10 and the guide device 20.

[0049] Before starting cutting, the body 10 is first installed on the support device 30 through the mounting blocks 14 on both sides. Taking the diamond wire cutting of silicon rods as an example, the accommodating chamber 11 of the debris box body 10 is filled with a certain height of cutting liquid. The technicians in this field can adjust the liquid level of the cutting liquid in the accommodating chamber 11 through the flow regulating member 22. During the cutting process, the silicon rod is immersed in the cutting liquid and feeds from top to bottom. Since the cutting part is immersed in the cutting liquid, the cutting liquid is easier to enter between the silicon wafers, thereby preventing the silicon wafers from sticking. During cutting, the rotation of the diamond wire can also drive the flow of the cutting liquid, further allowing the cutting liquid to take away the heat and debris generated during the cutting process. When the knife is retracted after the cutting is completed, the suction capacity between the silicon wafers is reduced, thereby reducing the risk of wire breakage and improving the efficiency of retracting the knife. Preferably, the mounting block 14 is set as a wedge block, and more preferably, the wedge block is an inverted equilateral triangle, and the flow regulating member 22 is set as a ball valve. In this embodiment, the width of the wedge block decreases from top to bottom, and the wedge block is plugged into the support device 30 of the debris box. By plugging the wedge block into the support device 30, the automatic centering positioning of the debris box can be completed.

[0050] It is understood by those skilled in the art that the arrangement of the sealing assembly 23 is not fixed. In an alternative embodiment, the pressing block 232 may not be provided, and the sealing of the connection between the body 10 and the flow guide device 20 can also be achieved by the sealing gasket 231 and the connecting member 233. Figure 4 As shown, although in the present embodiment, the first connection hole, the second connection hole and the third connection hole are all set to six, those skilled in the art can change them according to the needs. In an alternative embodiment, the first connection hole, the second connection hole and the third connection hole can also be set to four, five, seven, eight or more. Of course, the sealing component 23 can also be omitted, and only the fitting of the adapter 12 itself and the liquid inlet 211 can play a sealing role. In addition, the setting of the flow regulating member 22 is not static. In an alternative embodiment, the flow regulating member 22 can also be set to a clamp valve, a butterfly valve, a solenoid valve or other valves for regulating flow according to the needs of those skilled in the art, which is not limited here.

[0051] It should be explained that, although in the present embodiment, the outer diameter of the adapter 12 gradually decreases in the direction toward the flow guide box body 21, its specific setting is not set in stone. In an alternative embodiment, the outer diameter of the adapter 12 may also remain unchanged, as long as the adapter 12 can be inserted into the liquid inlet 211 and its outer edge keeps in contact with the liquid inlet 211. In the case of providing a sealing gasket 231, the inner diameter of the sealing gasket 231 only needs to be slightly smaller than the outer diameter of the adapter 12 to play a sealing role. However, considering the difficulty of connecting the main body 10 with the flow guide device 20, it is a better choice to set the outer diameter of the adapter 12 to gradually decrease in the direction toward the flow guide box body 21.

[0052] It can also be understood by those skilled in the art that the setting of the mounting block 14 is not set in stone. In an alternative embodiment, the mounting block 14 can also be set to other shapes. For example, the cross section of the mounting block 14 can be set to a circular, fan-shaped, T-shaped, etc., as long as the fixation of the debris box body 10 can be achieved. The support device 30 can also be changed accordingly according to the needs of those skilled in the art. In addition, the mounting block 14 can also be not set. In this case, the installation method of the debris box body 10 needs to be adjusted accordingly. In addition, the setting of the handle 13 is not necessary. In the case of setting the handle 13, those skilled in the art can also change the shape and height of the handle according to the needs. In an alternative embodiment, the direction of the handle 13 can be set to be horizontally outward, but considering the convenience of installation of the debris box and the limited installation space, setting the handle 13 in the vertical direction is a better choice.

[0053] The present application also provides a wire cutting machine, the wire cutting machine comprising any one of the above-mentioned debris boxes. Preferably, the wire cutting machine is a slicer.

[0054] When the above-mentioned debris box is used, the wire cutting machine or slicer enables the cut part to be cut by immersion cutting, improves the liquid-carrying capacity of the diamond wire, and thus improves the cutting efficiency. After the cutting is completed, the tool can be withdrawn by immersion, improving the wire breakage problem caused by silicon wafer clamping, thereby reducing costs.

[0055] It should be noted that although the present embodiment is described in conjunction with a slicer as an example, this is not intended to limit the scope of protection of the present application. Without departing from the principle of the present application, those skilled in the art may apply the present application to other application scenarios. For example, the fragment box of the present application may be used in other equipment that needs to be connected to a liquid, such as a mortar machine or a sawing machine.

[0056] Those skilled in the art will appreciate that, although some embodiments described herein include certain features included in other embodiments but not other features, the combination of features of different embodiments is meant to be within the scope of the present application and form different embodiments. For example, in the claims of the present application, any one of the claimed embodiments may be used in any combination.

[0057] So far, the technical solutions of the present application have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present application is obviously not limited to these specific embodiments. Without departing from the principles of the present application, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present application.
