Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of semiconductor production, and particularly relates to a wire welding and arrangement device of a cutting machine and the cutting machine. BACKGROUND

[0002] A semiconductor wafer is a substrate material for chip manufacturing, and a wire cutting machine is an important production device in the photovoltaic industry, which is used to cut a single crystal rod into a wafer. In work, a groove wheel is usually installed on the rack of the wire cutting machine, and a steel wire is wound around the outer periphery of the groove wheel. The cutting of the single crystal rod is completed through the cooperation of the groove wheel and the steel wire.

[0003] In the current single crystal cutting process, cutting abnormalities easily occur, causing the steel wire to break, and welding equipment needs to be used for welding to achieve the purpose of continuing cutting. Before welding, the steel wire of the wire net needs to be pulled out to two roots for operation, and after welding is completed, the welded steel wire is sent into the wire net in cooperation with the rotation of the groove wheel. Due to the influence of the tension between the steel wires and the differentiation of manual operation by personnel, the steel wire sent in is easy to have an excessively large inclination angle, causing the appearance of the wafer to be affected during secondary cutting, and even in the case that the broken wire area is too wide to connect the broken point of the steel wire, the single crystal uncut part needs to be cut off when starting, causing serious loss of the single crystal.

[0004] Therefore, a device for assisting the welding of the cutting machine is needed to assist the arrangement of the wire when the wire cutting machine breaks the steel wire and needs to be welded, to reduce the slope of the welded wire on the groove wheel and improve the quality of wafer cutting.

[0043] The technical solutions and other beneficial effects of the present application will become apparent from the following detailed description of specific embodiments of the present application, taken in conjunction with the accompanying drawings.

In addition, the terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first", "second" can explicitly or implicitly include one or more features.

[0045] The following disclosure provides many different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and arrangements of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application.

[0046] The first embodiment of the present application provides a cutting machine wire welding device 100, as shown in Figure 1 With Figure 2 As shown, comprising:

[0047] The first panel 110 has a first direction X;

[0048] The second panel 120 is movably connected with the first panel 110, and the first slide rail 121 is arranged on the second panel 120 along the first direction X;

[0049] The first pulley 130 is fixed on one side of the first panel 110;

[0050] The second pulley 140 is movably connected with the first slide rail 121, so that the second pulley 140 moves back and forth along the first direction X; wherein the second pulley 140 is located on the side of the second panel 120 close to the first panel 110.

[0051] When the steel wire in the cutting machine is broken, the two broken points of the broken steel wire need to be welded. After the steel wire is broken, an empty gap without steel wire is formed between the two broken points. In order to repair the steel wire, it is necessary to select direct welding of the broken points or use a welding wire to weld the two broken points respectively according to the width of the empty gap. However, due to the change of the interaction force between the broken steel wires, it may cause the reconnected steel wire to be inclined relative to the cut piece, and the large inclination of the steel wire will affect the cutting quality and even cause secondary breakage. The cutting machine welding wire routing device 100 provided by the embodiment of the application assists the welding operation when the steel wire is broken. The first pulley 130 and the second pulley 140 each have a V-shaped groove 131 for accommodating the welding wire. During welding, the steel wire or the welding wire is routed through the first pulley 130 and the second pulley 140, so that the threading mode of the welding wire is changed to winding using a pulley combination, breaking the bottleneck that the cutting broken position is too wide to thread or the inclination of the welding wire after threading is too large to cut. The bottleneck is effectively avoided, and the loss of single crystal after cutting the broken wire net is avoided due to the inability to thread. At the same time, since the second pulley 140 can move relative to the first pulley 130, the winding width can be flexibly adjusted, which can adapt to different axle distances under the condition of processing different specifications of silicon wafers, has high compatibility, and can be applied to a wide range of single crystal cutting scenes.

[0052] In some embodiments, the second pulley 140 is movably connected to the first sliding rail 121 through the first limiting block 122.

[0053] In some embodiments, the first pulley 130 and the second pulley 140 have the same diameter.

[0054] In other embodiments, the first pulley 130 and the second pulley 140 have different diameters.

[0055] As shown in Figure 3 some embodiments, the first pulley 130 has a first diameter D1, and the second pulley 140 has a second diameter D2. In the first direction X, the first pulley 130 and the second pulley 140 have a maximum distance L1, which satisfies: L1>0; and the axis of the second pulley 140 is arranged in the second panel 120.

[0056] In some embodiments, 80mm≤D1≤85mm.

[0057] It can be understood that the value of D1 (unit: mm) can be any one of 80, 81, 82, 83, 84, 85 or a range between any two values.

[0058] In some embodiments, 80mm≤D2≤85mm.

[0059] It is understandable that the value of D2 (unit: mm) can be any value among 80, 81, 82, 83, 84, and 85, or a range between any two values.

[0060] In some embodiments, 20mm ≤ L1 ≤ 420mm.

[0061] It is understandable that the value of L1 (unit: mm) can be any value among 20, 70, 120, 220, 320, and 420, or a range between any two values.

[0062] like Figure 3 As shown, it can be understood that the maximum spacing L1 is a unidirectional spacing along the first direction X, that is, the first pulley 130 and the second pulley 140 do not coincide in the first direction X. When the axis of the first pulley 130 is set at the first edge 111 and the axis of the second pulley 140 is set on the side of the second panel 120 away from the first edge 111, L1 has a maximum value. The second pulley 140 is always set in the direction away from the first edge 111 relative to the first pulley 130, thereby ensuring that the bonding wire is in a taut state after passing through the first pulley 130 and the second pulley 140 during the wire routing process.

[0063] In some preferred embodiments, L1≥D1+D2. That is, the first pulley 130 and the second pulley 140 do not coincide in the first direction X, and the second pulley 140 is always positioned in a direction away from the first edge 111 relative to the first pulley 130, thereby ensuring that the bonding wire is in a taut state after passing through the first pulley 130 and the second pulley 140 during the wire winding process.

[0064] like Figure 4 As shown, in some embodiments, the first panel 110 and the second panel 120 are movably connected by a first rotating shaft 150, which extends along a first direction X. The plane containing the first panel 110 intersects the plane containing the second panel 120 and forms an included angle α, where 0 < α ≤ 180°.

[0065] Understandably, the first panel 110 and the second panel 120 can rotate around the first pivot 150. On the one hand, this allows for further adjustment of the distance between the first pulley 130 and the second pulley 140 to ensure the welding wire is taut. On the other hand, by controlling the included angle α, the welding wire can be parallel to other steel wires when entering and exiting the welding wire wiring device 100 of the cutting machine, thus reducing the slope of the welding wire. The value of α can be any value or a range between any two of 30°, 45°, 60°, 90°, 135°, 150°, and 180°.

[0066] In some embodiments, such as Figures 1 to 3As shown, the cutting machine wire routing device 100 further comprises a third pulley 160;

[0067] The second panel 120 is further provided with a second sliding rail 123, which is connected with the third pulley 160 through a second limiting block 124, so that the third pulley 160 moves back and forth along the first direction X; the second sliding rail 123 is parallel to the first sliding rail 121, and the third pulley 160 is located on the side of the second panel 120 close to the first panel 110.

[0068] It can be understood that the second sliding rail 123 is arranged on the side of the first sliding rail 121 away from the first panel 110, so that the third pulley 160 can move on the parallel track below the second pulley 140. The third pulley also has a V-shaped groove 131 for accommodating the welding wire. When the broken wire forms a narrow swing cutting gap, only using the first pulley 130 and the second pulley 140 cannot meet the demand of aligning the broken wire. At this time, the first pulley 130, the second pulley 140 and the third pulley 160 are used to route the welding wire at the same time, and the welding wire is wound around the first pulley 130, the second pulley 140 and the third pulley 160 in turn, while adjusting the angle of the included angle a and the relative position between the three pulleys, so that the longer welding wire can also be in a tension state, ensuring the welding quality.

[0069] In some embodiments, as shown in Figure 3 As shown, along the first direction X, the side of the first pulley 130 close to the first edge 111 and the side of the third pulley 160 close to the first edge 111 have a second spacing L2, which satisfies:

[0070] 0 < L2 ≤ D1 + D2.

[0071] When the second spacing L2 satisfies the above condition, the second pulley 140 does not coincide with the first pulley 130 and the third pulley 160 in the first direction X, so as to ensure that the welding wire is in a tension state after winding around the first pulley 130, the second pulley 140 and the third pulley 160 during the winding process.

[0072] In some embodiments, as shown in Figures 1 to 3 As shown, along the first direction X, the first panel 110 has a first edge 111 and a second edge 112 arranged oppositely;

[0073] Wherein, the first pulley 130 is arranged on the side of the first panel 110 close to the first edge 111, the second pulley 140 is arranged on the side of the second panel 120 close to the second edge 112, and the third pulley is arranged on the side close to the first edge 111.

[0074] It can be understood that the first pulley 130, the second pulley 140 and the third pulley 160 are arranged in a staggered manner in the direction towards the cutting device 200, so that the three pulleys are more reasonable and dispersed in the overall layout of the wire winding, can uniformly share the tension of the welding wire, effectively prevent the welding wire from being worn and broken due to excessive local stress, and at the same time, it is beneficial to accurately guide the direction of the welding wire, so that the welding wire always maintains a stable path during the wire layout process, reduces the wire layout error, and thus reduces the slope of the welding wire on the cutting device 200.

[0075] In some embodiments, as shown in Figure 4 and Figure 5 The cutting machine wire layout device 100 further comprises:

[0076] The support 170 is connected to the second panel 120 at one end;

[0077] The base 180 comprises a third sliding rail 181 inside, the third sliding rail 181 is arranged along the first direction X and is connected to the end of the support 170 away from the second panel 120 through a third limiting block 182, so that the support 170 moves back and forth along the first direction X.

[0078] The support connects the second panel 120 and the base 180, and under the cooperation of the third sliding rail 181 and the third limiting block 182, the support 170 can accurately and smoothly move back and forth along the first direction X, so that the pulley combination in the cutting machine wire layout device 100 can quickly and accurately move to the specific position where the welding wire and the wire layout are required, effectively adapt to different specifications and layouts of the cutting machine welding wire operation scene, and improve the versatility and compatibility of the device. At the same time, the stable and reliable moving structure can ensure the stability of the cutting machine wire layout device 100 during position adjustment, avoid affecting the accuracy and quality of the wire layout due to shaking or displacement deviation, so as to ensure that the welding wire after the layout operation has no slope or has a small slope.

[0079] In some embodiments, the support 170 is movably connected to the second panel 120 through a second rotating shaft 190.

[0080] It can be understood that the second panel 120 can rotate around the second rotating shaft 190, so as to adjust the relative distance and the relative angle with the cutting device 200 during the wire layout, so that the welding wire can be wound out of the second panel 120 at an ideal angle.

[0081] In some embodiments, as shown in Figure 4 The support 170 is movably connected to the third limiting block 182 through a third rotating shaft 183. The support 170 can rotate around the third rotating shaft 183, so as to adjust the distance between the first panel 110, the second panel 120 and the cutting device 200.

[0082] The second embodiment of the present application provides a cutting machine, as shown in Figure 5 and Figure 6 The cutting device 200 includes a fixed assembly 210, a first pulley 130, a second pulley 140, a third pulley 160, a first panel 110, a second panel 120, and a wire welding and wiring device 100.

[0083] The fixed assembly 210 includes at least two grooved wheels 211 arranged at intervals, each of which extends along the first direction X.

[0084] The steel wire 220 is spirally wound around the outer periphery of the fixed assembly 210 to form at least two wire mesh surfaces 221 for cutting single crystals.

[0085] The wire welding and wiring device 100 is arranged outside any one of the wire mesh surfaces 221, and when the steel wire is disconnected, the wire welding and wiring device 100 can reconnect the steel wire 220 by welding.

[0086] The number of grooved wheels 211 can be two, three, four, or more, preferably three. The steel wire 220 is spirally wound around the outer periphery of the fixed assembly 210 formed by the grooved wheels 211 arranged at intervals, thereby forming multiple wire mesh surfaces 221. This design of multiple wire mesh surfaces 221 improves the efficiency of the cutting machine, allowing it to handle larger areas of single crystal material in a unit of time and shortening the processing cycle. The wire welding and wiring device 100 is arranged outside any one of the wire mesh surfaces 221, and when the steel wire 220 is disconnected, the wire welding and wiring device 100 can be moved to the position where the steel wire 220 is disconnected, and the distance and angle of the first panel 110 and the second panel 120 towards the wire mesh surface 221 are adjusted, and the spacing of the first pulley 130, the second pulley 140, and the third pulley 160 is adjusted to align with the breakpoint of the steel wire 220 for welding and wiring. The coordinated operation of the cutting device 200 and the wire welding and wiring device 100 enables real-time welding when a broken wire occurs during the cutting process, solving the problem of a wide cutting broken wire position that cannot be threaded, or a large slope after the wire is threaded, which effectively avoids the loss of single crystals after cutting the wire mesh.

[0087] In some embodiments, when the gap formed by the broken wire is wide, the first pulley 130 and the second pulley 140 can each connect the steel wire 220 by welding. The outer edge of the first pulley 130 is flush with one breakpoint, allowing the wire to be vertically wound into the first panel 110, and the outer edge of the second pulley 140 is flush with the other breakpoint, allowing the wire to be vertically wound out of the second panel 120.

[0088] In other embodiments, as shown in Figure 6As shown, when the gap formed by the broken wire is narrow, the first pulley 130 and the third pulley 160 can be connected by the welding wire respectively. The outer edge of the first pulley 130 is flush with one broken point, so that the welding wire can be vertically wound into the first panel 110, and the inner edge of the third pulley 160 is flush with the other broken point, so that the welding wire can be vertically wound out of the second panel 120.

[0089] It can be understood that the judgment of whether the gap formed by the broken wire is narrow or wide depends on the specific width of the gap formed by the broken wire and the diameters of the first pulley 130, the second pulley 140 and the third pulley 160 respectively. In some specific embodiments, when the gap formed by the broken wire is smaller than the sum of the diameters of the first pulley 130 and the second pulley 140, it can be judged that the gap formed by the broken wire is narrow; when the gap formed by the broken wire is greater than or equal to the sum of the diameters of the first pulley 130 and the second pulley 140, it can be judged that the gap formed by the broken wire is wide.

[0090] In some embodiments, the size of the base 180 in the first direction X is greater than or equal to the size of the wire net surface 221 in the first direction X.

[0091] It can be understood that the first panel 110 and the second panel 120 can be moved back and forth along the first direction X under the driving of the support 170, and controlling the size of the base 180 in the first direction X to be greater than or equal to the size of the wire net surface 221 in the first direction X can make the cutting machine welding wire layout device 100 can be slid to the corresponding position when the broken wire occurs at any position of the wire net surface 221, thereby assisting the layout of the welding operation.

[0092] In some embodiments, the groove wheel 211 includes a plurality of wire grooves for accommodating the steel wire 220, and the wire grooves are arranged along the first direction X, and the distance between every two adjacent wire grooves is equal.

[0093] It can be understood that each wire groove is perpendicular to the axial direction of the groove wheel 211, which is used to further ensure that each steel wire 220 wound on the groove wheel 211 is perpendicular to the axial direction of the groove wheel 211 and uniformly distributed on the outer periphery of the groove wheel 211, thereby ensuring the quality of the cutting machine.
