Description

Technical Field

[0001] The utility model relates to the technical field of wire cutting, and specifically provides a wire cutting machine. Background Art

[0002] Wire cutting machine is a kind of equipment which uses cutting wire (such as diamond wire, etc., with tiny diamond particles embedded on the surface of the diamond wire) to perform cutting operations such as truncation, squaring and slicing on hard and brittle materials to be processed (such as photovoltaic silicon materials (including single crystal silicon rods, polycrystalline silicon ingots, etc.), sapphire, magnetic materials, etc.).

[0003] Taking the slicer that slices photovoltaic silicon rods (referred to as silicon rods) as an example, the slicer directly operates the workpiece through the cutting mechanism. For example, under normal circumstances, the wire cutting machine mainly includes three cutting main rollers (two on the top and one on the bottom) distributed in an inverted triangle shape. The cutting main rollers are processed with dense annular grooves. By densely winding the diamond wire at the position corresponding to the annular groove, a continuous cutting wire network can be formed. Based on this, the diamond wire between the two upper cutting main rollers can cut the workpiece through the reciprocating flow of the diamond wire between the cutting mechanism and other structures of the wire cutting machine such as the retracting and releasing wire rollers.

[0004] However, when the slicer is running at high speed, the cutting fluid containing silicon powder attached to the diamond wire will inevitably be thrown out of the cutting area of ​​the slicer under the action of inertia and centrifugal force. In this way, if the silicon mud (silicon powder agglomerated under the premise of cutting fluid) thrown out of the cutting area falls on structures such as tension wheels and winding rollers, it will affect the slicing efficiency of the slicer to a certain extent and even cause the risk of diamond wire breakage.

[0005] Therefore, this field needs a new technical solution to solve the above technical problems. Utility Model Content

[0006] The utility model aims to at least partially solve the above-mentioned technical problems. Specifically, it solves the technical problem that after the silicon mud thrown out from the cutting area falls on structures such as the tension wheel and the winding roller, it may affect the slicing efficiency of the slicer to a certain extent and even cause the risk of the diamond wire breaking.

[0007] In view of this, the utility model provides a wire cutting machine, which includes a frame and a threading mechanism, wherein the frame forms a cutting area, and the wire cutting machine also includes a sealing assembly, wherein the sealing assembly includes: a base, which is arranged on the frame and forms a chamber capable of collecting cutting fluid from the cutting area; wherein a movable port is arranged on the frame and / or the frame base, and the threading mechanism can penetrate into the cutting area through the movable port; and a sealing structure, which is arranged at the movable port.

[0008] Through such a structure, it is possible to block the cutting fluid containing silicon powder into the chamber formed by the sealing component, thereby effectively avoiding the phenomenon that the silicon mud thrown out from the cutting area falls on structures such as the tension wheel of the tension mechanism and the winding roller of the retracting and releasing mechanism, thereby avoiding the problem that the slicing efficiency of the slicer is affected or even the risk of the diamond wire breaking caused by this. It is understandable that those skilled in the art can determine the structural form of the substrate, the number of components it contains, and the specific position of the substrate on the frame according to actual needs.

[0009] And by configuring a sealing structure on the moving port, the sealing performance of the sealing assembly can be better guaranteed. Those skilled in the art can determine the structural form of the sealing structure according to actual needs. It can be understood that those skilled in the art can determine the possible structural form and sealing performance of the sealing structure according to actual needs. Exemplarily, the sealing structure can be arranged in the entire area or a local area of ​​one or two of the moving ports. Exemplarily, a sealing structure is arranged in a local area of ​​one of the moving ports, and the sealing structure is movably arranged at a position of the substrate corresponding to the moving port.

[0010] For the above-mentioned wire cutting machine, in a possible implementation manner, the sealing structure has a free side that is not fixedly connected to the frame and / or the base, so as to allow the sealing structure to be opened during the movement of the threading mechanism along the moving opening.

[0011] By such a configuration, it is possible to ensure the cutting performance of the wire cutting machine by opening the sealing structure. Exemplarily, the sealing structure is a rigid structure and includes a plurality of sealing structures arranged along the moving direction of the threading mechanism, so that when the threading mechanism reaches the corresponding position, the sealing performance of the opened sealing structure fails or at least partially fails, while the sealing performance of the unopened sealing structure is still retained.

[0012] For the above-mentioned wire cutting machine, in a possible implementation manner, the sealing structure is a soft pad.

[0013] Through such a configuration, a specific structural form of the sealing structure is provided.

[0014] Since the sealing structure is a soft structure, when a part is opened, the other parts will still have a certain sealing effect due to the material. For example, the soft pad can be a rubber pad, a silicone pad, etc.

[0015] For the above-mentioned wire cutting machine, in a possible implementation manner, the flexible pad is fixedly connected to the frame and / or the base near the top.

[0016] With such a structure, it is possible to utilize the material of the sealing structure and gravity so that after a part is opened, the other parts will naturally fall down and the sealing performance will still be retained.

[0017] For the above-mentioned wire cutting machine, in a possible embodiment, the flexible pad is provided with a clamping mechanism so that: during the process of the flexible pad being opened, at least a portion of the free side is clamped by the clamping mechanism so that the free side is in or close to a position in a sealed state corresponding to the clamping position.

[0018] With such a configuration, it is possible to better ensure the sealing performance of the flexible pad.

[0019] It is understandable that those skilled in the art can determine the structural form and number of the pressing mechanism, the location where the pressing mechanism presses on the flexible pad, and the specific pressing method according to actual needs. For example, the pressing mechanism may include a plurality of pressing mechanisms arranged along the moving direction of the threading mechanism and fixed along the moving direction, and the pressing mechanism may press or release the flexible pad by rotating.

[0020] For the above-mentioned wire cutting machine, in a possible implementation manner, the clamping mechanism is movably disposed on the frame and / or the base.

[0021] With such a structure, it is possible to achieve a better sealing effect for the gasket through the activity of the clamping mechanism.

[0022] It is understandable that those skilled in the art can determine the specific form of the movable according to actual needs. For example, the pressing mechanism includes a rotating arm, one end of which is a pivot end and the other end is provided with a structure capable of pressing the soft pad, so that the sealing effect can be improved in the chord length area corresponding to the rotation range.

[0023] For the above-mentioned wire cutting machine, in a possible implementation manner, the clamping mechanism is movably disposed on the frame and / or the base.

[0024] With such a configuration, it is possible to achieve a dynamic sealing effect to a certain extent by accompanying the movement.

[0025] It is understandable that those skilled in the art can determine the specific direction and range of movement and the specific structure by which it is moved according to actual needs. For example, the direction of movement can be parallel to the moving direction of the threading mechanism or have a certain angle. For example, in order to prevent unnecessary interference, the clamping mechanism is made to clamp the soft pad in an inclined manner. For example, the clamping mechanism is a roller that is always in contact with the soft pad, and the driving component drives the roller to rotate through the transmission mechanism, thereby achieving follow-up clamping.

[0026] For the above-mentioned wire cutting machine, in a possible implementation manner, the clamping mechanism is arranged on the threading mechanism in a fixed connection or integrally formed manner.

[0027] With such a configuration, it is possible to achieve a certain degree of dynamic sealing by moving synchronously with the threading mechanism.

[0028] It is understandable that the pressing mechanism and the threading mechanism may be structures that are still independent of each other in terms of function, or they may be integrated to a certain extent under permitted conditions.

[0029] For the above-mentioned wire cutting machine, in a possible implementation manner, the pressing mechanism includes a guide wheel capable of pressing the flexible pad.

[0030] Through such a configuration, a possible structural form of the clamping mechanism is provided.

[0031] For the above-mentioned wire cutting machine, in a possible implementation manner, the wire cutting machine is provided with a support structure at a position corresponding to the moving port, and the guide wheel can abut against the support structure and thus clamp the flexible pad between the guide wheel and the support structure.

[0032] With such a configuration, it is possible to achieve better sealing of the flexible pad by means of the pressing mechanism.

[0033] It is understandable that those skilled in the art can determine the structural form, number of the support structure and the way of coordination between the support structure and the guide wheel according to actual needs. For example, the support structure can be a support groove, a curved plate, etc.

[0034] For the above-mentioned wire cutting machine, in a possible implementation manner, the supporting structure includes an inclined plate matching the guide wheel.

[0035] Through such a composition, a specific structural form of the supporting structure is given.

[0036] For the above-mentioned wire cutting machine, in a possible implementation manner, the guide wheel is configured with an elastic component.

[0037] With such a configuration, the guide wheel can better press the soft pad by means of the elastic force of the elastic member.

[0038] For the above-mentioned wire cutting machine, in a possible implementation manner, the elastic member is configured with an adjustment mechanism so that the elastic force of the elastic member can be adjusted by the adjustment mechanism.

[0039] With such a configuration, it is possible to adjust the pressing force of the guide wheel on the flexible pad by means of the adjustment mechanism.

[0040] For the above-mentioned wire cutting machine, in a possible implementation manner, the elastic member is a tension spring, the tension spring is connected to the guide wheel, and the adjustment mechanism is an adjustment screw capable of adjusting the preload force of the tension spring.

[0041] This configuration provides a possible structural form for the guide wheel to achieve its variable pressing force.

[0042] For the above-mentioned wire cutting machine, in a possible embodiment, the clamping mechanism includes: a first mounting part, on which the guide wheel is arranged; and a second mounting part, which is fixedly connected to the threading mechanism or is integrally formed, and the second mounting part is pivotally connected to the first mounting part; wherein, adjusting screws are respectively arranged on the first mounting part and the second mounting part, and the tension spring is arranged between the two adjusting screws.

[0043] Such a configuration provides a possible structural form of the pressing mechanism.

[0044] It is understandable that those skilled in the art can determine the specific form of the first / second mounting part, the number of groups of adjusting screw-tension spring-adjusting screw and their setting positions on the first / second mounting part and the specific setting method according to actual needs.

[0045] For the above-mentioned wire cutting machine, in a possible embodiment, the first mounting part is provided with a first guide wheel mounting structure and a second guide wheel mounting structure, guide wheels are respectively provided on the first guide wheel mounting structure and the second guide wheel mounting structure, and the first guide wheel mounting structure and the second guide wheel mounting structure are both pivotally connected to the second mounting part.

[0046] Through such a configuration, a specific structural form of the clamping mechanism is provided.

[0047] For the above-mentioned wire cutting machine, in a possible embodiment, a rotating shaft or a rotating sleeve is provided on the first guide wheel mounting structure and the second guide wheel mounting structure, and the second mounting part is correspondingly provided with a rotating sleeve or a rotating shaft at a position corresponding to the first guide wheel mounting structure and the second guide wheel mounting structure.

[0048] Through such a configuration, a specific method is provided for realizing the pivotal connection between the first mounting portion and the second mounting portion.

[0049] For the above-mentioned wire cutting machine, in a possible embodiment, the second mounting part includes a first sub-part and two second sub-parts extending from the first sub-part, wherein the first sub-part is integrated with the threading mechanism and is provided with a vertical wire routing groove; and the two second sub-parts are correspondingly provided with a rotating sleeve or a rotating shaft at positions corresponding to the first guide wheel mounting structure and the second guide wheel mounting structure.

[0084] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. For example, although the sealing structure of the additional clamping mechanism at the position of the moving port is introduced in this embodiment, this is not intended to limit the scope of protection of the present invention. Without departing from the principles of the present invention, those skilled in the art may adopt other forms of sealing structures. In addition, without introducing a sealing structure, the construction of the chamber has been able to substantially solve the technical problems corresponding to the sealing assembly.

[0085] In addition, although the present embodiment is introduced in combination with a wire cutting machine having an axially movable first / second wire retracting and releasing mechanism, this is not intended to limit the scope of protection of the present invention. Obviously, the cutting mechanism of the present invention is also suitable for a traditional wire cutting machine with a six-guide wheel structure.

[0086] It should be noted that in the description of the present invention, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0087] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "setting", and "connection" 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, an indirect connection through an intermediate medium, or the internal connection of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0088] In addition, in order to better illustrate the present invention, many specific details are given in the following specific embodiments, and those skilled in the art should understand that the present invention can also be implemented without certain specific details. In some examples, the principle of the slicer well known to those skilled in the art is not described in detail in order to highlight the main purpose of the present invention.

[0089] The equipment forms of wire cutting machines mainly include cutters, squarers and slicers. Taking the workpiece to be processed as silicon rods as an example, the cutter is mainly used to cut the longer silicon rods into shorter silicon rods. Specifically, a silicon rod is cut into multiple sections by cutting along the radial direction of the silicon rod. The squarer is mainly used to cut a silicon rod with a circular cross section (such as a round rod) into a silicon rod with a rectangular cross section (such as a square) (such as a square rod). Specifically, the edge of the round rod is removed by cutting along the axial direction of the silicon rod to cut the round rod into a square rod. The slicer is mainly used to cut the square rod that meets the precision standard intensively and continuously along its radial direction by multi-wire cutting to obtain the thin slices to be used. Under normal circumstances, the precision standard is ensured by grinding the edges / sides of the square rod. The utility model is mainly improved for the slicer with a wire mesh.

[0090] Main reference Figure 1 and Fig.10In a possible embodiment, the slicer 100 mainly includes a frame 1, wherein the frame is provided with a first pay-off and retracting mechanism 21 and a second pay-off and retracting mechanism 22 on the left and right sides respectively, and the main structure of the first / second pay-off and retracting mechanism is a winding roller, and the diamond wire as a cutting wire can realize the pay-off and retracting function (the pay-off and retracting functions can be interchanged). The frame is provided with a cutting mechanism 3 in the cutting area corresponding to the slicer, such as in this example, the cutting mechanism includes a first cutting main roller 31, a second cutting main roller 32 and a third cutting main roller 33 distributed in an inverted triangle, wherein the cutting main rollers (31, 32) are located above the third cutting main roller 33. A first tension mechanism 41 and a second tension mechanism 42 are respectively provided between the third cutting main roller 33 and the first pay-off and retracting mechanism 21 and the second pay-off and retracting mechanism 22, and the pay-off and retracting rollers of the two pay-off and retracting mechanisms are lower than the tension wheels of the tension mechanisms on the same side. In this way, through the reciprocating motion of the diamond wire between the two pay-off and retracting rollers, the tension wheels on the corresponding sides and the cutting mechanism, the silicon rod can be cut along its radial direction to obtain a silicon wafer. Specifically, the diamond wire wound by the retractable and retractable roller in the "release" function is guided to the main roller mechanism composed of the cutting main rollers (31, 32, 33) through the tension wheel on the corresponding side, and then guided to the retractable and retractable roller in the "retract" function through another tension wheel. The retractable and retractable rollers on both sides alternately retract and release the wire. Based on this, the silicon rod 9 moving downward can be cut by the diamond wire 8 between the cutting main rollers (31, 32) located above. The first tension mechanism 41 and the second tension mechanism 42 are respectively installed on the first linear module 51 and the second linear module 52 fixed on the frame to realize the axial movement of the tension mechanism. The wire cutting machine also includes two threading mechanisms 6 corresponding to the first tension mechanism 41 and the second tension mechanism 42. The right end of the threading mechanism is fixedly connected to the first / second tension mechanism on the corresponding side, and the left end extends into the cutting area. For example, a first wiring groove 61 and a second wiring groove 62 are provided on the threading mechanism 6. In this embodiment, a sealing assembly 7 is respectively arranged at the position of the frame corresponding to the cutting area close to the first / second tension mechanism. As in this example, the frame has a stepped surface 11 at this position, and the sealing assembly is arranged on the inner side of the stepped surface.

[0091] Main reference Figures 2 to 5In a possible embodiment, the sealing assembly 7 includes a base 71, which includes an integrally formed side portion 711 and a top portion 712, and the side portion 711, the top portion 712 and the step surface 11 of the frame enclose a chamber capable of collecting the cutting fluid from the cutting area. Among them, the top portion is divided into an inclined surface that tilts downward from left to right, so that the cutting fluid in the cutting area can flow down along the inclined surface in a timely manner, thereby avoiding the deposition of silicon mud on the top surface. A drain port 721 is provided on the lateral area of ​​the step surface (the bottom of the chamber), and the drain port 721 is provided with a drain pipe 722 capable of discharging the cutting fluid on the outside of the bottom of the chamber. In addition, a guide plate 723 is provided near the drain port in the chamber so as to guide the cutting fluid entering the chamber to the area near the drain port in a timely manner.

[0092] Main reference Figure 2 , Figure 6 and Figure 7 In a possible embodiment, a cleaning port 7121 and an observation port 7122 are provided on the top surface portion 712 of the base body. The cleaning port is mainly used to clean the silicon mud deposited in the chamber during the regular maintenance of the slicer. The observation port is mainly used to facilitate the operator to observe the situation of the diamond wire in the threading mechanism, the routing of the diamond wire after it is broken, etc. The first cover plate 7123 and the second cover plate 7124 are respectively configured at the positions corresponding to the cleaning port and the observation port on the top surface portion. In this example, the first cover plate is screwed to the top surface portion because the cleaning port is used less frequently. The observation port is used more frequently, so the second cover plate is pivotally provided to the top surface portion in this example. Exemplarily, a mounting seat 71251 is provided on the top surface portion, a connecting shaft 71252 is provided on the mounting seat, and the second cover plate is pivotally provided on the connecting shaft. For example, a handle 71241 for easy operation is also provided on the side of the second cover plate away from the connecting shaft. A moving port 7111 is provided on the side portion 711 of the base body, and the threading mechanism 6 can move along the moving port. In addition, a moving opening with a substantially similar structure is also provided in the vertical area of ​​the step surface, so that the threading mechanism can extend to the cutting area through the two moving openings and move within the area defined by the two moving openings. The following mainly takes the moving opening provided on the side part of the base as an example for explanation.

[0093] Main reference Figure 3 A silicone pad 73 is arranged at the position of the base body corresponding to the moving opening. The upper side of the silicone pad is fixed to the side part of the base body through the edge strip 731, and the lower end is a free side. In this way, a sealing curtain can be formed. Since the silicone pad is a soft structure, when the threading mechanism moves along the moving opening, a partial area of ​​the sealing curtain is opened to allow the threading mechanism to move normally, while the other parts can cover the moving opening to play a sealing role. On this basis, continue to refer to Figure 5A clamping mechanism 74 may be provided on the lower side of the silicone pad. In this way, when the silicone pad is opened, the free side is clamped by the clamping mechanism to ensure that the silicone pad obtains a better sealing effect as much as possible when it is opened.

[0094] Main reference Figure 5 , Figure 7 and Figure 8 In a possible embodiment, the clamping mechanism 74 mainly includes a first mounting portion 741 and a second mounting portion 742 integrally formed with the right side of the threading mechanism (the second wiring groove 62 is arranged on the second mounting portion 742), and the two ends of the first mounting portion 741 are connected to guide wheels 743 through two guide wheel mounting structures 744, and the two guide wheel mounting structures are respectively provided with rotating shafts 7471, and the second mounting portion is correspondingly provided with rotating shaft sleeves 7472 that cooperate with the rotating shaft, and the first mounting portion and the second mounting portion are pivotally connected through the cooperation of two pairs of rotating shafts / sleeves. In addition, two tension springs 746 with pre-tightening force are arranged between the first mounting portion and the second mounting portion, and with the help of the pre-tightening force of the tension spring 746, the guide wheel can reliably press the lower side of the silicone pad. In order to better cooperate with the guide wheel, a support plate 748 is added to the side portion of the base body corresponding to the lower edge of the moving port. For example, the support plate is a bent structure composed of a vertical plane plate and an inclined plate in an inclined direction. In this way, the vertical plane plate is fixed to the side portion of the base body by screwing or the like, and the guide wheel can abut against the inclined plate and thus clamp the lower side of the silicone pad between the two. Preferably, two first adjustment screws 7451 and two second adjustment screws 7452 are respectively installed on the first mounting portion and the second mounting portion, and two tension springs 746 are respectively arranged between the first adjustment screw and the second adjustment screw at the corresponding position. In this way, the preload force of the tension spring can be adjusted by a pair of adjustment screws, thereby better ensuring the pressing effect of the guide wheel on the silicone pad.

[0095] On this basis, continue to refer to Fig. 9 , which shows another embodiment of the clamping mechanism. The principle of this embodiment is similar to Figure 8 The structures shown are basically the same, the only difference is that: Figure 8 In the embodiment shown in FIG. 1 , the compression spring is pulled downward, whereas in the present embodiment, the tension spring is pulled upward.

[0096] It can be seen that in the sealing assembly of the utility model, the cutting liquid thrown out by the diamond wire in the cutting area is temporarily collected in the chamber through the chamber constructed by the base body, thereby effectively avoiding the phenomenon that the silicon mud thrown out from the cutting area falls on structures such as the tension wheel of the tension mechanism and the winding roller of the take-up and pay-out mechanism, and thus avoiding the problem that the slicing efficiency of the slicer is affected or even the risk of the diamond wire breaking caused by this. By adding a silicone pad to the moving port, it is possible to further prevent the cutting liquid from reaching the tension mechanism and the take-up and pay-out mechanism through the moving port. On this basis, by configuring a clamping mechanism for the silicone pad, an effect similar to dynamic sealing can be obtained.

[0097] So far, the technical solution of the present invention has 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 invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, 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 invention.
