The methods include a plurality of method steps for implementing various functions of the device. [Embodiment] Various embodiments of the present invention are described in detail below, and one or more examples thereof are illustrated in the drawings. In the following description of the drawings, the same elements represent the same elements. In general, only the differences of the individual embodiments are described. The various embodiments are provided to explain the invention and are not intended to be construed as limiting. Further, features illustrated or described as part of an embodiment can be used in other embodiments or in combination with other embodiments to yield further embodiments. We intend to include such changes and changes in the description. Further, in the following description, a wire management unit will be understood as a device that processes the supply of a wire to a work area of a wire sawing device such as a cutter, a squarer, or a wafer-cut wire saw. Typically, the wire saw includes a wire guide for conveying and guiding the wire in the direction of wire movement while the wire management unit provides control of the wire tension. Further, the wire provided by the wire management unit forms a wire mesh as described above. In the following, a wire mesh will be identified as a mesh formed by a single wire management unit. It should be understood that a wire mesh may contain more than one work area, where the work area is defined as the area in which the sawing process is performed. Typically, embodiments of the wire guides described herein are suitable or provided for use in a wire sawing device, which may be used in a wire sawing device 8 201134571 and/or may be a wire sawing device Part of it. In addition to other aspects that may be used to fit or set any pulley or other components described herein, such a pulley may have a grooved structure that is configured to direct a thickness of 40 〇μηη or less or a thickness of Any of the other diameter wires described above. By this, it should be noted that the groove structure is specifically designed for the wire diameter and the cutting process in order to allow high-precision cutting (e.g., 25 μm or less, or even 5 μm or less). As shown in Fig. 1, in the wire sawing device, the wire 1 is supplied from the spool 12. The wire 10 is released from the spool 12 during the sawing. Thereby, the spool rotates about its axis 12a. Figure i shows that the wire 1〇 is being carried on the wire carrying area of the reel $13a丨. In the wire cutting device 1, the wire 10 is guided from the spool 12 over the pulleys to the pulleys 20, 3, which rotate about respective pulley axes (e.g., 32). Next, the wire 10 is guided to a cutting area where a wire web is formed. Thereby, for example, the wire 10 is conveyed through the wire sawing device γ 100'. Here, you can understand the main frame system.

The ground is moved from one side of the reel to one of the main frame portions of the main frame, which is part of the device, which is the base of the device during operation. Therefore, when the wire tube is mounted on the main frame portion, the wire is tied to the side (flange to flange) when the field is opened. This can be seen by the 201134571 bursting of the thread that was loosened from the different positions of the reel 12 as shown by the dashed line showing the thread 1 〇 ' at a different position from the thread. For advanced wire sawing devices, such as cutters, square cutters or wire saws, there is a desire to cut hard materials such as semiconductor materials (e.g., tantalum, quartz, or the like) at high speed. The wire speed, which is the speed at which the wire moves through the wire cutting device, the wire management unit, and the material to be cut, may be, for example, 1 〇 m/s or higher. Typically, the wire speed can be 15-20 m/s. However, higher wire speeds of 25 m/s or 3 〇 m/s are also desirable and can be achieved under certain conditions. In order to loosen the wire at the desired wire speed, the drum is rotated at a rotational speed of up to several thousand revolutions per minute. For example, 1〇〇〇-2_ rpm can be supplied to loosen the wire. Therefore, as shown in Fig. i, the different positions of the wire 10 from the reel 12 are also changed at a relatively high speed, and the angle at which the wire 10 enters the pulley 20 is correspondingly changed. Thus, the angle between the wire at the reel 12 and the entrance of the fixed pulley groove at the slide #2 periodically changes. This change creates a shock in the wire as the wire slides from one side of the pulley groove to the other side. This change eventually causes the wire to climb up the side wall 23 of the groove. These vibrations are detrimental to the process' because they create a high risk of wire breakage (e.g., when the wire is accommodated on the pulley groove sidewall 23 and the amplitude of the shock moves up and down) due to the tension in the wire. Again, this is particularly relevant when there is a desire for a thinner wire diameter and a diamond coated wire, because in these cases the wire will break even more easily. Again, the change in the position of the varying thread on the barrel 12, and in particular the entry of the thread (7) into the pulley 2011 10 201134571, causes fluctuations in the wire sawing device which can deteriorate the cutting accuracy. To this end, the fixed sheave 20 can be replaced by a movable sheave that is longitudinally movable in the direction of the parallel reel axis 12a. Movable; the bone wheel can be fitted with a tracking system that allows it to follow the position where the wire moves from one side of the reel to the other, so that the wire always enters the pulley tangentially. Such a pulley system is described in, for example, European Patent Application No. EP 9153 519, the disclosure of which is incorporated herein by reference in its entirety in its entirety in its entirety in its entirety in its entirety, in its entirety in The narrative of the graph tracking system and its corresponding narrative. However, due to the relatively high tension of the wire sometimes, it is difficult to sufficiently support the movable sheave so that the movable sheave can withstand high wire tension. Undesirable deformation and vibration of the pulley support, the movable wheel and the wire can occur if the movable pulley is not sufficiently supported. Such vibrations again cause undesirable fluctuations in the wire' and in some cases cause the wire to break. As a result, it is hoped that the wire management unit can be improved, thereby reducing the above difficulties. According to one embodiment described in Fig. 2, a wire sawing device 1 is provided. In the wire sawing device, there is a wire management unit, and some components of the wire management unit are shown in Fig. 2. According to various embodiments, the wire sawing device can be a cutter, a square cutter, a wire saw or a multi-wire saw. Thereby, the cut-off can be understood as a device which can be used to cut from a block or a block which has been separated into a plurality of blocks in a squarer. 201134571 A saw blade is a wire saw. It roughly cuts the saw block into blocks of a desired size so that a wire saw or a multi-wire saw can cut the wafer from the block in a wafer forming process. The wire management unit here is a wire sawing device which is particularly suitable for a squarer, but is not limited to a squarer. The wire management unit of Fig. 2 includes a spool 212 having a spool axis 2112a. The reel is carried by a reel shaft 21〇. The spool shaft 210 is rotatably mounted to the main frame portion (10) for rotation about the spool axis 212a. Thereby, the spool shaft 21 rotates the spool about the spool axis 212a. The reel shaft rotation can be driven by a reel motor. In contrast, the pulley system to be described hereinafter is substantially freely rotatable. On the reel 212, the wire 1 supplied to the wire web is carried in a wire carrying area 213a of one of the reels. The wire carrying area 213a has a wire carrying length in the direction of the spool axis 212a. During the unwinding of the wire 1 from the spool 212, the wire is supplied towards the wire mesh of the wire saw. A first pulley 220 is shown in FIG. Here and generally, the pulley has a groove adapted to guide the wire. Further, the pulley generally has a wire guiding position for guiding a wire in the pulley, i.e., in the pulley groove. The first pulley 220 is adapted to receive a wire from the spool 212 (especially directly from the spool 212) and then redirect the wire. The first pulley system is rotatably mounted to a pulley carrying unit 224 such that the first pulley 22 is rotatable about the first pulley axis 222. The pulley carrying unit 224 is in turn coupled to a wire sawing device (more specifically, to the main frame portion of the wire sawing device 1) such that the pulley carrying unit 224 can move longitudinally along a 12 201134571 pulley motion (ie, The pulley motion track is defined as the area in which the pulley carrying unit moves. Thereby, the first pulley motion track of the first pulley (i.e., the track along which the first pulley 220 can move longitudinally) is also defined. Still further, as a general aspect, the first pulley motion track can have a length of at least 9% of the length of the wire carrying region 213a of the spool 212. Here, the wire carrying area 213a is the length segment of the wire 212 from which the wire can be exposed from the reel, i.e., substantially the length from the flange of the reel to the flange. As a further general aspect, the pulley motion can extend across the length of the wire carrying area 213a from the flange to the flange. The main frame portion 1 is rigidly connected or rigidly connectable to the wire sawing device base. Thereby, the main frame portion 1 is very strong, and for example, the load on the main frame portion can be absorbed by the base. The main frame portion can be made in one piece or in multiple pieces (such as pieces 110 and 112 in Fig. 2). Here, these pieces! The 丨〇 and 丨丨 2 are rigidly connected to each other, for example by screws or some other connector. Without being affected by the embodiment shown, the main frame portion 1 is integrally rigidly coupled to the base of the wire sawing device during operation. The pulley motion of the pulley 220 is substantially parallel to the spool axis 212a. According to embodiments that may be combined with any of the other embodiments described herein, other directions of movement may overlap to the above movement. For example, one of the curved tracks and/or one of the inclined tracks can be provided as compared to the spool axis 212a. In Fig. 2, the pulley carrying unit 224 is shown as a standard. In other embodiments that may be combined with any of the other embodiments described herein, 201134571 - load-bearing pulley 220 pulley carrier unit 224 may be provided as a rod or another support such that it can rotate about axis 222 - the pulley axis The 222 series is oriented relative to the spool axis η. It is 90 in nature. The angle. Here, the angle is defined as a spatial angle, that is, the angle of the axes in the plane across the axes (if necessary) 'translating on one of the axes of the axes such that the axes intersect and straddle - After the plane). This angle is defined as an absolute angle, which is always positive. In accordance with an embodiment described herein, a pulley moving device is provided. The pulley shifting device 228 is shown by the arrows in Figure 2 and is adapted to move the pulley retainer 224 in a U-mode motion. The pulley moving device 228 is adapted to move the pulley 22 and the wire position (4) device along the moving track (here parallel to the axis 2 i 2a of the drum) in order to position the pulley at a desired position above the spool 212. The pulley moving device 228 can be, for example, a linear actuator (such as a linear motor), a pneumatic cylinder, a motor with a worm drive, a bracket-rack-gear, or the like so that the pulley moving device can be at least along Move the (four) wheel with the direction of the pulley's motion track. Thereby, the pulley can be moved relative to the main frame portion 100 of the thread cutting device by moving the π wheel carrier 224. A wire position detecting device 226 can be provided in accordance with a further embodiment that can be combined with other embodiments described herein. The wire position detecting device detects the direction along the moving path (here, the position of the thread along the axis of the reel, in more detail, the detecting wire crosses the wire position 201134571. The position of the wire of the area is measured. Thereby, the position of the wire 10 from the reel 212 or the wire carrying area 213a can be obtained (by triangulation if necessary). The wire position detecting device 226 is connected to the pulley moving device 228. For example, a signal receiving unit, a controller, a computer for calculating the correct pulley position, etc. may be provided between the wire position detecting device 226 and the pulley moving device 228. In a specific embodiment, the controller system may Operatively coupled to the wire position detecting device 226 for receiving the detected wire position. The controller determines a target position and transmits a movement command to the first pulley moving device 228 to move the first pulley moving device The first pulley to the target position. In particular, the target position may be a position corresponding to the position where the wire 10 leaves the reel. By the target position, the wire is phased. Leaving the reel at a right angle to the pulley axis 2123, as shown in Fig. 2. The first pulley moving device 2 28, the wire position detecting device 226 and the first pulley position controller may be collectively referred to as a first pulley wire tracking system. In general, the __first-pulley wire and longitudinal system can be provided to respond to the detected position of the detected wire by the first pulley moving device 228. Further, as a general aspect, the pulley of the first pulley 2 2 0 The track system is arranged such that for any position of the wire 10 away from the wire carrying area 213a of the coil 212, there is a first pulley to > position 'on the pulley moving track so that the wire line enters the first z-month substantially tangentially Wheel 220. Further, in general, the first pulley 220 (and any other pulley, right present in the embodiment, such as the second pulley 230 described below) may be arranged by 15 201134571 such that the material is removed from the coil 212 The wire bearing area 213 & ^ location, at least one position of the first pulley 220 is present on the pulley moving track so that the wire is substantially tangentially separated and enters either the coil and the pulleyThis arrangement allows for a thread that does not twist. Here, "non-twisting" means that the wire enters and exits the coil and pulley of the wire management unit substantially tangentially. As an opposite example, the wire shown in Figure i (which enters and exits the pulley 20 non-tangentially) will twist. Thus, the controller can be programmed to actuate the pulley moving device 228 for any position of the wire 1 〇 away from the wire carrying unit 213a, thereby causing the wire to enter the first pulley 22 实质上 substantially tangentially, particularly such that the wire does not substantially twist . Continuing with the description of the embodiment of Figure 2, the wire management unit of Figure 2 has a second pulley 230 adapted to receive the wire from the first pulley 220 (especially directly from the first pulley) and to redirect The wire first pulley 230 is rotatably mounted to the main frame portion and rotatable about the second pulley axis 232. In general, further pulleys can be provided in the wire management unit. The thread is re-guided by the first pulley 22〇9〇. The first re-orientation angle' is redirected 180 by the second pulley 230. The second redirection angle. Due to the large second re-directing angle, a major portion of the wire tension (especially in the case of a tension spike) is absorbed by the second pulley, which is stably supported by the main frame portion 1〇〇. Due to the stable support of the main frame portion 100, the second pulley 230 can withstand tension more easily and stably than the movable first-slide 220. Thereby, it is possible to reduce the deformation and vibration of the movable pulley 220 and thus the wire, which is not expected. Therefore, it is also possible to reduce the fluctuation of the wire itself, the member of the wire cooking unit, or other members of the wire cutting device. Furthermore, the risk of wire breakage can be reduced. This allows for higher thread speeds and thus higher thread yields. In general, the m-line is redirected by the first pulley to no more than 12G. The first-redirect angle' and if the wire is redirected by the second pulley is not less than 60. The second redirecting angle ' absorbs the tension of the wire to a certain extent by firmly attaching the second slider 230. In the example of Fig. 2, the redirection angle is independent of the position of the first pulley 220 on the first motion track, but more generally the 'first pulley 22' must be satisfied at least one position on the first motion track. The above situation. In this second embodiment, which can be combined with any of the other embodiments described herein, the first pulley can even satisfy the above situation at any position on the first motion track. In some embodiments, the second redirect angle is °100° or less, or even 9〇. Or smaller. Also, in some embodiments the 'second redirect angle is no less than 90. , no less than 120 or even 18 inches. . Here, the redirection angle is defined as the entire deflection angle of the wire deflection. Thus, for example, a quarter-rotation will result in a skew angle of 9 , and a three-quarter rotation will result in 270. The skew angle is absent, and the direction of the skew is taken. The skew angle is taken as an absolute value and therefore the total deviation is. Again, an alternative and substantially useful configuration can be represented as follows: In a configuration, the second redirection angle is greater than the first redirection angle. In this configuration, the load received by the second pulley due to the wire tension of the wire may be greater than the load received by the first pulley. Again, this can help to avoid the excessive load on the movable first pulley on 17 201134571. A further alternative and substantially useful configuration can be indicated as follows: In a configuration, the redirecting angle is selected such that the pulley 2, the material tension of the wire iQ, receives a greater load than the first pulley 220. In Fig. 2, the first and second re-directing angles are directed to opposite winding directions. This allows for a particularly small configuration and also allows for particularly effective wire tension absorption of the second pulley. Furthermore, the first pulley axis 222 and the second pulley shaft and line 232 are qualitatively parallel to each other. More generally, in an embodiment, the first pulley axis 222 and the second pulley axis 232 can have less than 9 turns relative to one another. Angle. Further, in Fig. 2, the wire 10 is deflected by the first pulley 220 in a direction away from the wall member of the main frame 1〇〇. Next, the wire 10 is deflected by the second pulley 23〇 in a direction toward the wall member 11 () of the main frame 1〇〇. Furthermore, the pulley movement track in Fig. 2 is parallel to the wire segment of the wire/line (7) between the first/moon wheel 220 and the second pulley 23G. Thereby, for any position of the first pulley 22G, the wire between the first and second pulleys extends in a direction (i.e., parallel to) the direction of movement of the pulley. This means that the orientation of the wire is not affected by the position of the first pulley 22 on the pulley motion. For any position of the first pulley, the first pulley and the second pulley are arranged to each other such that the thread is tangentially Leaving the first pulley and feeding it tangentially to the second pulley, or not twisting. Further, if a thin wire or wire having a coating (e.g., a diamond coating) is used, the spool shaft can be particularly useful. In particular, the spool shaft is suitable; therefore, in the embodiment of any other implementation 201134571 j »: described herein, the wire processing portion and the wire sawing device described herein are: Suitable for thin wires having a diameter of less than about 400 (e.g., about 2 〇〇 _ μιη, more specifically about 2 〇〇 μηη to about the claw). However, in other cases, the embodiment may also have a straight line of light as small as, for example, 10 or even η. Further, the wire processing portion and the wire cutting system described herein are applied to the coated wire, for example, a wire having a recording coating in which diamond particles are embedded. Such a wire may typically have a diameter of from about (iv) to about 4 angstroms, such as from 31 〇μηη to 340 μΓη. The reel shaft disclosed herein is particularly useful for diamond threads because it may be necessary to remove the diamond thread (especially from time to time), such as for a two-way saw or for a substantially short length of wire. A thread of increased risk of twisting of the wire, a loss of 4-wire or damage to the coating is advantageous as shown in Figure 2. By using a diamond thread, the production = an increase of 2 or even a larger multiple. In the case of a squarer, a throughput rate of 1 〇〇 MW or even greater can be achieved in this way. When the diamond thread is used, the silk and silk feed-step material can be applied to the drill wire. For example, 'mechanical parts, electrical parts and (4) software can be used for the use of diamond threads. In the following, further embodiments are described, the elements of which may be combined with any of the other embodiments described herein. In the following description, only elements that are different from the elements of the foregoing embodiments or the elements of other embodiments described herein are described. It should be understood that the components, aspects, and details described in connection with the other embodiments may be applied to embodiments that do not describe all components, aspects, or details. 19 201134571 Figure 3 shows a further embodiment in which the first pulley 220 is in a position different from that of Figure 2 on the pulley motion track (i.e., away from the main frame portion 100). Further, Fig. 3 depicts some variations of the embodiment described in Fig. 2. All of these variations can be included in the embodiment of Figure 2 independently of each other. As a first variation in Fig. 3, a recess 116 is provided in the main frame portion 1A. The recess is sized and the recess is arranged to at least partially receive the first pulley 220. This recess allows the first pulley 220 and thus the spool 212 to be arranged closer to the main frame portion 1' while still allowing the first pulley motion track to cover most or all of the wire carrying area 2 1 3 a. As a step change in Fig. 3, the main frame portion 100 of Fig. 3 is integrally formed as a single piece, instead of including some components as shown in Fig. 2. The main frame portion 1〇〇 may even be integrally formed in the main frame as one and the same member. As a step-by-step change in FIG. 3, a third pulley 24 is provided, and the third pulley 240 is adapted to receive a wire from the second pulley 230 (especially directly from the second pulley 230) and to redirect the wire Three Re-Guided Angles - The first π wheel 240 is rotatably mounted to the main frame portion 旋转 for rotation about the third pulley axis 242. The third pulley axis 242 is substantially perpendicular to the spool axis 212a and the second pulley axis 232. Thus, the wire exits the third pulley 24 (in the right side of the second pulley 240 in the figure) in a direction perpendicular to the image plane of Fig. 3, so that the redirection angle is 90. . Figure 4 is a schematic illustration of one of the wire management units 20 201134571 in accordance with a further embodiment. Here, the reel 212, the wire 10, the first, second and third pulleys 22, 230 and 240 mounted on the spool shaft 210 of Fig. 3 are shown. In contrast to the side view of Fig. 3, Fig. 4 shows a front view of the reel 212 (from the left side of Fig. 3) facing the direction of the spool axis 212a. Further, Fig. 4 shows a fourth pulley 250 which receives the wire from the second pulley and redirects the wire to a fourth redirection angle. The fourth pulley 250 is rotatably mounted on the frame for rotation about the fourth pulley axis 252. Here, the fourth redirection angle is about 9 〇. . In other embodiments, the fourth redirection angle can be between 6 〇〇 and 丨 2 。. Between. The fourth pulley axis 252 is substantially parallel to the spool axis 212a.

Independent of the one shown, the first pulley 220 and the second pulley 230 are mounted on a common assembly (especially on a one-piece dream component). The general aspect. Flying Mount Figure 6 shows a perspective view of the Stereo 23 201134571 of the Wire Management Unit of the further step embodiment. The embodiment of Fig. 6 includes the elements shown in Fig. 5, and the above description of Fig. 5 is also applied to Fig. 6. Also, a fourth pulley 25 is displayed. The fourth pulley 250 is arranged as shown in Fig. 4, so that the corresponding Fig. 4 description is also applied to Fig. 6. The fourth pulley is mounted on the mounting member 114. The embodiment of Figure 6 further includes a wire tensioner for controlling the tension of the wire. The wire tensioner includes a fifth pulley 26 and a sixth pulley 270. The fifth pulley 26 is rotatably mounted to the frame and rotates about the fifth pulley axis 262. The sixth pulley 27 is rotatably mounted to A movable jaw 274 rotates about the sixth pulley axis 272. The movable jaw 274 is movably mounted on the main frame portion. Movement of the movable element 274 can be controlled by a motor, or the movable element 274 can be pre-biased, for example, by a spring to control wire tension. In Fig. 6, the movable member 274 is shown as a pre-biased rotary lever. The wire tensioner receives the wire 1 from the fourth pulley 250 and provides a wire 1 to the wire mesh (to the right of the wire management unit shown in Figure 6). More precisely, the fifth pulley 260 receives the wire 1〇 from the fourth pulley 25〇 and deflects the wire to a fifth skew angle, and then the sixth pulley 26〇 receives the wire 10 from the fourth pulley 250 and is skewed Silk - the sixth skew angle. With the χ-yz reference frame defined above, the embodiment of Fig. 6 is a general aspect that satisfies at least one state selected from the following (and all states in some embodiments): - Silk The tensioner is located on one side of the reel 2 1 2 , substantially relative to the first pulley 220 ; the wire between the fourth pulley and the thread tensioner (in more detail, the second and fifth of 2011 34571 in the fourth and fifth The wire between the pulleys extends mainly along the 2 axes; - the wire between the fifth pulley and the sixth pulley extends mainly along the 7 axis; the wire leaves the sixth pulley and is substantially parallel to the y axis; The sixth pulley has a direction substantially extending from the χ direction; the fifth re-guide angle of the pregnancy is about 60. To 90. (In more detail, about 8 〇 to 90 °); - The sixth re-guide angle is about 18 〇. . In general, in embodiments that may be combined with any of the other embodiments described herein, the pulleys have at least one of the following radii (and in some embodiments all of the following radii): reel shaft 21Q has a diameter of about 15 〇. The first pulley 220 and the second pulley 230 have a diameter of __ to 150 mm, particularly U2 mm (here, the diameter means the diameter traversed by the thread, i.e., the diameter within the wire guiding groove). The third pulley 240 has a diameter of 140 to 170 mm, in particular 158 mm. The fourth pulley 250 has a heart similar to the first pulley 22〇. The fifth pulley 260 and the sixth pulley 27A have a diameter similar to that of the third pulley. Continuing with the description of Fig. 6, in addition to the wire processing unit 200 (which will be referred to as a main wire processing unit in the following), the wire management unit of Fig. 6 also has a primary wire processing unit 300. Here, the terms "main" and "under-required" are used, which are used for easy identification, and do not mean silk processing. Any order or functional order of p, reel, etc. The secondary wire treatment is constructed similarly to the main wire processing portion and has elements corresponding to the elements of the main wire processing portion. The secondary wire portion 25 201134571 is labeled as a "minor" component and assigned component symbols 310, 312, etc., and corresponds to the "main" components 21, 212, etc. of the corresponding primary wire processing portion 200. . Therefore, the secondary wire processing unit has, for example, a secondary reel shaft 31 for the reel 312, a first pulley 320, a second pulley 33, and the like. The secondary first pulley 320 is rotatably mounted to the primary pulley carrier unit 324 and rotates about the secondary first wheel axis 322. The secondary pulley carrier unit 324 can be moved longitudinally along the secondary pulley motion track. The secondary wire processing units 200 and 300 are placed adjacent to each other in the x-direction. As a general aspect (shown by the illustrated embodiment but independent of the embodiment shown), the primary and secondary wire processing sections 2, 3 can be disposed on a common wall portion of the main frame section (10). That is, the primary and secondary wire processing sections 200, 300 can be disposed in a common tolerance of one of the wire sawing devices. Further, it can be seen from Fig. 6 that the main reel 212 and the second reel have different types (the slit is not present in the front flange of the secondary reel 312). In general, according to any of the embodiments described herein, the secondary thread processing portion 300 is formed in the same manner as the thread processing portion. Therefore, the description of the elements of the main wire processing unit 200 can be applied to the corresponding elements of the secondary wire processing unit 300. In the -operation example mode (hereinafter referred to as primary to secondary reel cutting) 'the main wire processing section provides the wire from the main - (four) 212 to the mesh) so that the wire can be used for the cutting of the wire. Next, the secondary wire processing portion receives the wire 1〇β from the mesh whereby the wire 1〇 is transferred from the mesh 26 201134571 to the secondary wire tensioner (more precisely to the secondary sixth pulley 370) and then To the fifth pulley 36 〇, from here to the second heart here - the second pulley 34 〇, from here to the second pulley 3 3 0, from here to 丨丨 + _ $ ±人<·><·* 攸 攸 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The movement of the pulley motion track is such that the wire is wound onto the wire carrying area of the secondary reel 312 in a controlled manner. In order to receive the wire, the first pulley controller at a time includes a wire winding pattern and is programmed to determine a desired wire winding position for winding the wire on the secondary winding wire and to transmit a movement command to the secondary first The pulley moving device 328 is configured to enable the secondary first pulley moving device 328 to move the secondary first pulley 32 to the desired wire winding position. The secondary second pulley 3 3 0 re-directs the wire about 8 〇. And the second pulley again guides the wire about 90. . Due to the large secondary second pulley 33〇 re-directing the angle, severe tension and fluctuations during winding of the wire (as explained above) can be avoided, so that the wire can be entangled stably with a reduced risk of wire damage. Therefore, independent of the embodiment of Figure 7, the secondary second pulley 330 should redirect the wire no less than 6 turns. And the secondary first pulley re-guides the wire to be no greater than 120. . In general, the type of reel (i.e., the first reel type) in which the new filament is provided is different from the type of reel on which the used filament is wound (i.e., the second reel type). For example, a reel provided with a new wire may be a disposable reel from a wire manufacturer. On the other hand, such a reel may not be suitable for receiving the used thread, which is due to the fact that such a reel sometimes has a high thread tension that cannot be tolerated by the used thread. In order to support these different reel types during the primary to secondary reeling of the saw, the main reel shaft (i.e., the reel shaft of the v-wang wire processing section) may be adapted to carry the first type of reel, and. The person wants the spool shaft (i.e., the spool shaft of the secondary wire processing portion) to be adapted to carry, and to carry, the second type of spool, i.e., the second type is different from the first type. In the embodiments, which may be combined with any of the other embodiments described herein, the wire management unit may support bidirectional cutting. Here, the bidirectional cutting is known as the _cut 4 mineral processing process. During the cutting process, the wire is first transferred from the main reel to the person who wants to be wounded, and then from the secondary volume.

Please be transferred back to the main squad, and again from the main reel to the secondary reel. Thus, for bidirectional (four), the (primary) reel 212 is adapted to provide a wire to the wire web and is also adapted to receive the used wire from the wire web. In the same manner, the second reel 3 I2 may be adapted to provide a wire to the wire mesh, and also, it is also suitable for receiving the used wire from the wire mesh. For both sides 1^7 ·1:7Ι ★ Knife saw, a controller is adapted to send an actuation command to the main cylinder shaft and to the secondary reel shaft 'actuation command system so that the first reel shaft is loose in a first step Opening the wire to the second reel and causing the second reel to unwind the wire to the first reel in a second step. Fig. 7 is a perspective view showing the upper portion of the ice knives from the wire arranging unit according to a further embodiment described herein. The embodiment of Fig. 7 generally corresponds to the embodiment of Fig. 4, except for the features mentioned below, except for the arrangement of the Κ pulley which is most worthy of the note. Here, in the χγζ coordinate system, the X thin β丄 is defined by the reel axis 212a, and the y axis is 28 201134571 is defined by the first roll _232 (pointing to the vertical direction), and the first pulley axis 222 can be The position is inclined in the Z direction or in the 2 direction, but in the Η plane. The second and third pulley axes 232, 242 are in the y direction. The fourth pulley axis 252 is in the z direction. Here, the wire U) is deflected by the first pulley 22 (four) in the direction of the wall element of the main _ 1 〇 0. Then, the wire is deflected away from the main frame by the second pulley 23〇! (9) The direction of the wall element. In this embodiment, the first skew angle is about 9 〇. The second and third skew angles are about 18 〇 ° ' and the fourth skew angle is about 90. . Figure 8 shows a top view of the wire cutting device 其 (which is a _ squarer). The square cutter includes a wire management unit, and the wire management unit has a first wire processing unit 200 and a second wire processing unit 3〇〇. Further, the wire cutting device 1 has a guard zone right, and the wire ig is formed in the blade zone 41 - the wire mesh 41 (), and the actual (four) process is performed in the wire mesh 410. The first wire processing portion 2" and the second wire processing portion 3" are included in accordance with any of the embodiments described herein (for example, the embodiment shown in Fig. 6). The wire processing sections 200 and 3 each have a wire spool and a plurality of pulleys for guiding the wire 10 toward the wire mesh 410. The wire saw 1 further includes pulleys 420, 430 for re-introducing the V wire from the wire management unit to the wire mesh. Further, in the work area 4, a plurality of pulleys 412 are arranged to guide the wires, thereby establishing a wire mesh. In Fig. 6, the square cutter of a matrix-like matrix is shown to have cut wire segments in two mutually opposite parent directions. a wire mesh can have in the two phases

29 S 201134571 For example, six cutting wire segments in each of the mutually positive directions. Alternatively, a network of cut-off wires can be provided, for example, in U.S. Patent Application Serial No. 0815,449, the entire disclosure of which is incorporated herein by reference. In the work area 4, a sample supply line (not shown) is provided for carrying the sample to be sawed. The sample supply plate has a plurality of grooves so that during the sawing, the wires can pass through the grooves while the sample is carried by the remainder of the plate. Furthermore, the wire management unit has a cooling system 5〇〇. The cooling system 500 includes a coolant tank 5 10 for storing a coolant (generally slurry), a coolant supply line 520 for supplying coolant from the coolant tank 5 to the working area, and a use The coolant return line 53 is returned from the working area 4 to the coolant return line 53. The coolant supply line 520 has a plurality of nozzles for spraying the coolant to the wire in the wire mesh. . The nozzles can be arranged along the square boundary of the wire web 410. Although only one supply line 52A is shown, there may be more than one supply line, for example, each side of the square boundary of the wire mesh has a supply line (ie, there are four supply lines in total) 'each supply line supplies coolant to a plurality of sprays Nozzles (e.g., each side of the wire web 410 has six spray nozzles for each of the six wire segments). In the case of diamond threads, no aggregates are required, but it is still advantageous to cool the diamond threads during cutting. Accordingly, the slurry can be replaced by some other coolant such as a water-based cooling liquid. Accordingly, the cooling system can be advantageously adapted to a water system cooling liquid, as described below. Figure 9 shows a spray nozzle 54 特别 which is used in particular for the use of non-destroyed 30 201134571 2 such as water-based coolants. The money nozzle 540 is sprayed, and the crucible supply line 52G receives the coolant and is adapted to the /7 agent to the wire 10. The spray nozzle 540 is substantially formed into a shape of a cylindrical body, and the body of the column has a vertical cylindrical axis to the right. The circle has a notch (which is located on the left side of the body of FIG. 9). A nozzle outlet is provided in the middle. In Fig. 9, (iv) the nozzle system 54 is sprayed with some coolant onto the wire 10 in the spray direction 542. Here, the coolant spray has some expansion, and the spray direction 542 (dashed line) is: the center of the spray or the main direction 'where the expansion is around the spray. The angle 544 between the spray direction 542 and the wire 10 is 9 〇. To 18 baht. , to 170 (especially about 15 〇.) is advantageous. This large angle allows for sufficient wire cooling by cooling the liquid. Moreover, such a large angle allows the spray of coolant to always be on the wire 10, independent of the grooves used on the wire guide. Figure 10 is a perspective view showing one of the cooling system 500 of the cooling system 500 of Figure 8 "The coolant tank is suitable for non-slurry coolants (especially water-based coolants)" and is therefore particularly useful for diamond threads. of. The coolant tank system has a coolant tank volume 5 10 for storing coolant liquid. Again, the return line 530 is directly connected to the coolant tank volume to directly return the coolant liquid from the working area of the wire saw to the coolant tank volume 51 (see also Figure 8). Here, direct return means that there is no pump in the return line 530 between the working area 400 and the coolant tank volume 510. Further, the coolant tank return line 530 is connected to the coolant tank volume 5 1 0 at a connection portion of the coolant tank volume 5 1 〇. Advantageously, the connection 31 201134571 °P is at the bottom of the blade, which is arranged below the minimum coolant level during normal operation. The absence of both pump and arrangement at the bottom of the coolant tank volume 51〇 significantly reduces the formation of bubbles in the coolant tank volume 5丨〇 (which is a problem for the aqueous coolant liquid) The return line 530 can optionally also include a feed line for filling the fresh coolant supply to the trough volume 5 1 。. Further, the coolant tank volume 5 1 〇 is shaped and an inclined bottom surface (the guide The outlet (not shown) at its lowermost portion is matched. Again, the tank volume 51 is connected to the coolant liquid supply line 520 via a pump 522 (eg, a pneumatic pump). Any of the embodiments described herein can be used. In combination with the general aspect, the controller of the cooling system 500 can have a discharge program that is programmed to cause the actuator of the outlet to open the opening to discharge the tank (ie, remove all of the coolant liquid from the tank ( In addition to the possible small amount of residual coolant)). In other embodiments, the pump 522 or a further fruit (eg, aerodynamic fruit) is coupled to a drain line (not shown). In this case, the drain program may alternatively or additional The ground is stylized so that the pump delivers the coolant liquid from the tank to drain the tank. This allows for easy replacement of the coolant without the need to remove the coolant tank volume 5 1 0 from the wire sawing device.
