Description

Technical Field

[0001] The utility model relates to the technical field of wire cutting, and specifically provides a deflection detection mechanism, a wire saw unit and 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] Take the slicer that slices photovoltaic silicon rods with a wire cutter as an example. The slicer directly operates the workpiece through the cutting mechanism. For example, under normal circumstances, the wire cutter 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 cutter such as the retractable wire roller.

[0004] Reference Figure 1, the diamond wire of the existing slicer is between the winding rollers 01 of the left and right winding and releasing mechanisms. The cutting mechanism of the slicer usually includes two or three main rollers, and in this example, there are three main rollers, namely, the main roller 1 021 on the upper left, the main roller 2 022 on the upper right, and the main roller 3 023 on the lower side). In addition, the slicer includes at least six guide wheels, three of which are arranged on the left and right sides, taking the left side as an example, they are the wire arrangement wheel 03, the tension wheel 04, and the reversing wheel 05. Based on this structure, the winding path of the slicer is: the winding roller on the left (taking the winding roller as the wire release roller (the winding roller on the right is the winding roller at this time) as an example, it is obvious that the function of the winding roller can be switched between the winding roller and the wire release roller. For example, assuming that the winding roller on the left is the winding roller, the winding roller on the right is switched to the wire release roller accordingly) → the left side (wire arrangement wheel, tension wheel, reversing wheel) → main roller three → main roller two → main roller one → the left side (reversing wheel, tension wheel, wire arrangement wheel) → the right winding roller. Take the slicer with six guide wheels as an example. When the slicer is in working state, the top of one of the three guide wheels on the left (and the three guide wheels on the right) that directly cooperate with the bottom of the other guide wheels are in the same linear plane, so the problem of deflection (such as oblique pulling when arranging the wire) is not obvious. However, due to the large number of guide wheels, it is often accompanied by tension fluctuation. The probability of tension fluctuation can be reduced or the level of tension fluctuation can be reduced by reducing the number of guide wheels in the slicer. However, with the reduction in the number of guide wheels (such as omitting the wire arranging wheel between the winding roller and the tension wheel), in the case of deflection problem, the diamond wire entering or leaving the tension wheel will have a deflection angle with the wire groove of the tension wheel, which will cause friction between the cutting wire and the wire groove of the tension wheel. For the wire groove of the tension wheel, it will increase the wear of the wire groove and affect the service life of the tension wheel. For the diamond wire, the probability of wire breakage is increased. In order to avoid the above problems caused by the deflection problem, it is necessary to detect the state of the diamond wire in time so that the diamond wire can be corrected in time when the deflection problem occurs.

[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 technical problems, specifically, to solve the technical problem of how to detect a diamond wire with a deflection problem so as to correct the deflection in time.

[0007] It should be noted that the background technology only illustrates the necessity and urgency of proposing the present invention through a scenario with a more obvious deflection problem. Obviously, the deflection detection mechanism of the present invention can also be used to detect the state of the diamond wire (between the tension wheel and the wire arrangement wheel) on the slicer with a six-guide wheel structure described in the background technology.

[0008] In the first aspect, the utility model provides a deflection detection mechanism comprising: a trigger mechanism, which includes a first trigger end and a second trigger end, and the first trigger end and the second trigger end can move towards / away from each other, so that: in the stage where the cutting line needs to be deflected, the first trigger end and / or the second trigger end are close to each other, so that: when the cutting line to be detected touches any one of the first trigger end and the second trigger end, the circuit is turned on, thereby detecting the state of deflection of the cutting line.

[0009] With such a configuration, it is possible to detect the problem of the diamond wire being deflected by pulling in the first trigger end and the second trigger end.

[0010] It is understandable that those skilled in the art can determine the specific way in which the first trigger end and the second trigger end achieve their approaching / distancing position change according to needs, such as by movement, rotation, or a combination of the two under the action of an external force or with the help of a certain mechanism, and the mechanism can be any one or more of which can achieve telescopic movement.

[0011] In addition, it is understandable that those skilled in the art can determine the specific form of the first / second trigger end according to actual needs, such as a charged metal rod, a carbon rod, etc.

[0012] Regarding the above-mentioned deflection detection mechanism, in a possible implementation manner, the deflection detection mechanism includes: a movable component, which can drive the first trigger end and / or the second trigger end to move closer to / away from each other in a moving and / or rotating manner.

[0013] With such a configuration, it is possible to seek a possible motion mode of a structure that can realize a detection state.

[0014] For example, the first / second trigger end can be moved closer or farther away in the radial direction (when placed vertically) / axial direction (when placed horizontally) to realize the construction of a narrow space that is more easily touched, or the first / second trigger end can be rotated along a certain axis to change the distance between the parts closest to each other.

[0015] For the above-mentioned deflection detection mechanism, in a possible implementation manner, the movable component includes a driving component, and the driving component can drive the first trigger end and / or the second trigger end to move and / or rotate.

[0016] With such a configuration, it is possible to achieve a structure in which the detection state is realized by the driving member.

[0017] It is understandable that the first trigger end and the second trigger end may share a driving component or may be respectively configured with a driving component. Taking respectively configuring a driving component as an example, the structural form, installation position and corresponding driving mode of the two driving components may be the same or different.

[0018] For the above-mentioned deflection detection mechanism, in a possible implementation manner, an insulating component is provided at the power output end of the driving component, and the first trigger end and / or the second trigger end are provided on the insulating component.

[0019] With such a configuration, it is possible to prevent the first trigger end and / or the second trigger end from contacting other metal parts, thereby causing the circuit to be turned on and affecting the deflection detection result.

[0020] It is understandable that technical personnel in this field can determine the structural form of the insulating component and the connection method between the power output end and the insulating component according to actual needs, such as direct connection or indirect connection, and the insulating component can be a disc-shaped structure, a rod-shaped structure, a groove-shaped structure, a block structure, a plate-shaped structure, etc.

[0021] For the above-mentioned deflection detection mechanism, in a possible implementation manner, the driving component includes two power cylinders capable of respectively driving the first trigger end and the second trigger end to move.

[0022] Through such a configuration, a specific configuration mode of the driving component is provided. For example, the power cylinder can be a pneumatic cylinder, an electric cylinder, a hydraulic cylinder, etc.

[0023] For example, a mounting component may be provided at the power output end of the power cylinder, and an insulating component may be provided on the mounting component. The reason for such a setting is that: the structure of the power output end is relatively fixed and the insulating component has a certain function that is strongly related to the detection effect, so changes to these two components may affect the reliability and accuracy of the deflection detection mechanism. Based on this, a connection link can be added. For example, under the premise that the mounting component is connected to the power output end, the structure of the mounting component and the connection method with the insulating component can be adjusted according to the structure of the insulating component, such as bonding, clamping, or fixed connection with the aid of fasteners.

[0024] For the above-mentioned deflection detection mechanism, in a possible implementation manner, the first trigger end and / or the second trigger end is pivotally disposed on the deflection detection mechanism,

[0025] The driving component can drive the first trigger end and / or the second trigger end to rotate.

[0026] Through such a configuration, a specific setting method of the first / second trigger end is provided.

[0027] It is understandable that those skilled in the art can determine the specific implementation method of the driving component driving the first / second trigger end to rotate on the pivot side according to actual needs, such as by direct connection or indirect connection. Exemplarily, the driving component is a motor, and the rotation of the motor directly drives the first / second trigger end to rotate.

[0028] For the above-mentioned deflection detection mechanism, in a possible implementation manner, the deflection detection mechanism includes a shaft, and the first trigger end and / or the second trigger end is arranged on the shaft.

[0029] The driving component can drive the first trigger end and / or the second trigger end to rotate around the axis or drive the first trigger end and / or the second trigger end to rotate along the axis.

[0030] Through such a configuration, a possible implementation method for rotating the first / second trigger end is provided. For example, the drive component and the shaft can be directly connected or indirectly connected. For example, the shaft is rotatable, the first / second trigger end is coaxially arranged and fixedly connected to the shaft, and the power output shaft of the motor is coaxially arranged and fixedly connected to the shaft.

[0031] For the above-mentioned deflection detection mechanism, in a possible embodiment, the driving component is a power cylinder, the power output end of the power cylinder is pivotally connected to the connecting rod assembly, the connecting rod assembly includes at least one connecting rod, one end of the connecting rod assembly is pivotally connected to the power output end, and the other end of the connecting rod assembly is pivotally connected to the shaft or the first trigger end and / or the second trigger end.

[0032] This design provides a possible structural form of the drive transmission connection.

[0033] For the above-mentioned deflection detection mechanism, in a possible implementation manner, when the connecting rod assembly includes multiple connecting rods, the multiple connecting rods are pivotally connected to each other; and / or the axis is a fixed axis, the first trigger end and / or the second trigger end can rotate around the fixed axis, and the other end of the connecting rod assembly is pivotally connected to the first trigger end and / or the second trigger end; and / or the two connecting rod assemblies corresponding to the first trigger end and the second trigger end are pivotally connected to the same power cylinder.

[0034] Through such a configuration, a possible implementation method of the first / second trigger end detecting the state based on the rotation structure is provided.

[0035] Exemplarily, the power output end of the power cylinder is fixedly connected to the aforementioned insulating component, and one end of the two connecting rod assemblies is pivotally connected to the insulating component respectively.

[0036] In a second aspect, the utility model provides a wire saw unit, comprising the deflection detection mechanism as described in any one of the above items.

[0037] It can be understood that the wire saw unit has all the technical effects of the deflection detection mechanism described in any of the above items, which will not be repeated here.

[0038] In a third aspect, the utility model provides a wire cutting machine, which comprises the deflection detection mechanism or wire saw unit as described in any one of the above items.

[0039] It can be understood that the wire cutting machine has all the technical effects of the deflection detection mechanism described in any of the above items, which will not be repeated here.

[0040] For the above-mentioned wire cutting machine, in a possible implementation manner, the wire cutting machine is a slicer.

[0041] Through such a structure, a specific structural form of the wire cutting machine is provided. BRIEF DESCRIPTION OF THE DRAWINGS

[0063] 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 present embodiment is introduced in combination with the first / second counterweight (block, rod) arranged on the first / second mounting arm, it is obvious that those skilled in the art can adjust the number, setting position, setting method (movable or fixed) and specific activity method of the configuration blocks included in the counterweight group according to actual needs, such as one part can only rotate and another part can only move, etc.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] Main reference Figure 2, the utility model first reduces the number of guide wheels of the wire cutting machine. In a possible embodiment, the slicer 100 includes a frame and a first retractable wire mechanism 21 and a second retractable wire mechanism 22 arranged on the frame. The main structure of the first / second retractable wire mechanism is a retractable wire roller, and the diamond wire as the cutting wire can realize the retractable function (the retractable function can be interchangeable). Among them, the frame is provided with a cutting mechanism in the cutting area corresponding to the slicer. For example, 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 arranged between the third cutting main roller 33 and the first retractable wire mechanism 21 and the second retractable wire mechanism 22. The retractable wire rollers of the two retractable wire mechanisms are lower than the tension wheels of the tension mechanisms on the same side. Taking wire release as an example, after the diamond wire on the retractable wire roller is wound around the tension wheel, it enters the cutting area of ​​the slicer through the threading mechanism. For example, one side of the threading mechanism is mounted on the tension wheel motor mounting seat of the first / second tension mechanism, and the other end extends into the cutting area of ​​the slicer. The threading mechanism is provided with a wire groove that allows the diamond wire to pass through the wire groove. For example, a drainage port is left in the wire groove to drain and discharge the cutting liquid thrown out by the diamond wire in time, so as to avoid the accumulation of silicon mud on the threading mechanism, especially in the wire groove. The main function of the threading mechanism is to protect the diamond wire from breaking due to external interference by allowing the diamond wire to pass through the wire groove of the threading mechanism. In this way, through the reciprocating movement of the diamond wire between the two retractable rollers, the tension wheel on the corresponding side 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 roller in the "release" function is guided by the tension wheel on the corresponding side to the main roller mechanism composed of the cutting main rollers (31, 32, 33), and then guided by another tension wheel to the retractable roller in the "retract" function. The retractable rollers on both sides perform retracting and retracting alternately. Based on this, the silicon rod 7 moving downward can be cut by the diamond wire 6 between the upper cutting main rollers (31, 32). As described in the background technology, when the number of guide wheels is reduced, the problem of deflection will be aggravated. Therefore, in the utility model, a deflection detection mechanism is arranged between the first retractable wire mechanism and the first tension mechanism on the left side and between the second retractable wire mechanism and the second tension mechanism on the right side, so as to timely know the problem of deflection of the diamond wire. Under this premise, by moving the retractable wire roller along its axial direction, the diamond wire is returned to its position in the case of deflection of the diamond wire, thereby realizing the correction function. For example, in the rewinding stage of the diamond wire (before cutting each knife (diamond wire cutting section), the wire consumption required for the process is first quickly wound and placed on the rewinding side of the two retractable wire mechanisms. When cutting, the rewinding side can be used as the pay-off roller to achieve reverse cutting), the deflection detection mechanism of the utility model can be used to detect the deflection problem of the diamond wire.

[0069] The following describes the deflection detection mechanism of the present invention by taking the first wire-retracting and -releasing mechanism and the first tension mechanism as an example.

[0070] Main reference Figure 3 to Figure 4 In a possible implementation, the deflection detection mechanism 5 mainly includes a trigger mechanism, and the trigger mechanism includes a first trigger end 51 and a second trigger end 52. For example, the first / second trigger end can be a charged metal rod or a carbon rod. The first trigger end and the second trigger end can move in a manner of approaching / moving away from each other, so that in the stage where the deflection of the diamond wire between the retractable roller of the first retractable mechanism 21 and the tension wheel of the first tension mechanism 41 needs to be detected (such as the rewinding stage), the two trigger ends are close to each other to form a narrow space. In this way, once the diamond wire has a deflection problem, it will touch one of the trigger ends, thereby causing the circuit to be turned on.

[0071] Embodiment 1:

[0072] Main reference Figure 4 In a possible implementation, the first trigger end and the second trigger end are both in a vertically arranged state, and the two can approach / move away from each other by moving radially. In this example, a cylinder 53 is configured for each of the (first and second) trigger ends, and both cylinders are arranged on the base of the deflection detection mechanism. By introducing compressed gas into the gas circuit assembly, the power output ends of the two cylinders can be extended, thereby driving the (first and second) trigger ends to approach each other.

[0073] In order to prevent the (first and second) triggering ends from contacting other metal parts and thus causing a conducting circuit, an insulating block 54 is provided at the power output end of the cylinder, and the first / second triggering end is provided on the insulating block on the corresponding side. For example, a mounting block 55 that can better match and connect with the insulating block is first provided at the power output end of the cylinder, and then the insulating block 54 is provided on the mounting block 55.

[0074] Based on the above structure, the following mainly refers to Figure 5 and Figure 6 To illustrate the principle of the deflection detection mechanism of the utility model to achieve deflection detection.

[0075] like Figure 5 As shown, when deflection detection and the corresponding correction operation are not needed, the power output ends of the two cylinders are in a retracted state. At this time, the power output ends of the two cylinders respectively drive the mounting blocks and the insulating blocks on the corresponding sides to withdraw to both sides, and the distance between the first trigger end 51 and the second trigger end 52 arranged on the insulating block becomes larger, reserving a larger routing space for the diamond wire, that is, the diamond wire can hardly touch the first trigger end and the second trigger end.

[0076] like Figure 6 As shown, when deflection detection and the corresponding correction operation are required, compressed air is introduced into the two cylinders so that the power output ends of the two cylinders extend out. At this time, the power output ends of the two cylinders respectively drive the mounting blocks and insulating blocks on the corresponding sides to approach each other, and the distance between the first trigger end 51 and the second trigger end 52 set on the insulating block becomes smaller, that is, a smaller gap is formed between the two, so that only a small routing space is left for the diamond wire. If the diamond wire has a deflection problem at this time, the diamond wire will touch the first trigger end or the second trigger end. When the touch occurs, the circuit of the trigger mechanism is turned on, causing the voltage signal in the circuit to change, so that the reminder / alarm to start the correction program can be triggered or the correction program can be directly entered.

[0077] In this example, the execution action corresponding to the correction program is: the retracting and releasing roller moves in the opposite direction along its axis, so that the deflected diamond wire can be pulled back, until the diamond wire is separated from the first trigger end or the second trigger end, and the correction operation is considered to be completed. At this time, the distance between the two charged metal rods or carbon rods is still relatively close. If no further detection is required, a larger routing space can be reserved for the diamond wire by retracting the power extension end of the cylinder.

[0078] Embodiment 2:

[0079] Main reference Figure 7 and Figure 8 In a possible implementation, the first trigger end 51 and the second trigger end 52 are in a vertically arranged state when deflection detection and the corresponding correction operation are not required, and the shortest distance between the two is the distance between the axes of the first trigger end 51 and the second trigger end 52. When deflection detection and the corresponding correction operation are required, the vertical state is switched to a horizontal state, and the shortest distance between the two is the distance between the right end surface of the first trigger end 51 and the left end surface of the second trigger end 52. The first / second trigger ends are moved closer to / away from each other by rotation. For the convenience of comparison and description, the cylinder and the insulating block in this embodiment still use the numbers in Example 1.

[0080] In this example, the (first and second) trigger ends share a cylinder 53, the power output end of the cylinder is connected to an insulating block 54, and the (first and second) trigger ends are both pivotally arranged on a fixed pin 56. A connecting rod assembly 57 is respectively arranged between the insulating block 54 and the pin 56 corresponding to the (first trigger end and the second trigger end), and the two ends of the connecting rod assembly are respectively hinged to the insulating block 54 and the first / second trigger end on the corresponding side. Exemplarily, the connecting rod assembly includes two connecting rods hinged to each other.

[0081] The principle of implementing deflection detection based on the deflection detection mechanism of this embodiment is similar to that of the embodiment.

[0082] like Figure 7 As shown, when deflection detection and the corresponding correction operation are not needed, compressed air is introduced into the cylinder so that the power output end of the cylinder extends. At this time, the power output end of the cylinder drives the insulating block to move upward. The upward movement of the insulating block will drive the first trigger end 51 and the second trigger end 52 to pivot apart through the connecting rod assembly, thereby switching from a horizontal setting state to a vertical setting state. At this time, the shortest distance between the two becomes larger, reserving a larger routing space for the diamond wire, that is, the diamond wire can hardly touch the first trigger end and the second trigger end.

[0083] like Figure 8 As shown, when deflection detection and the corresponding correction operation are required, the power output end of the cylinder is retracted. At this time, the power output end of the cylinder drives the insulating block to move downward. The downward movement of the insulating block will drive the first trigger end 51 and the second trigger end 52 to pivot closer through the connecting rod assembly, thereby switching from a vertically set state to a horizontally set state. At this time, the closest distance between the two becomes smaller, that is, a smaller gap is formed between the two, so only a smaller routing space is left for the diamond wire. If the diamond wire has a deflection problem at this time, the diamond wire will touch the end face of the first trigger end or the second trigger end. When the touch occurs, the circuit of the trigger mechanism is turned on, causing a change in the voltage signal in the circuit, so that a reminder / alarm to start the correction program can be triggered or the correction program can be directly entered. The execution action corresponding to the correction program is similar to that in Example 1 and will not be repeated here.

[0084] It can be seen that in the deflection detection mechanism of the present invention, the deflection detection before correction is achieved by the movement of the two trigger ends based on the trigger mechanism. Specifically, at the stage where the deflection of the diamond wire needs to be detected, a state that can detect the deflection of the diamond wire in a voltage-triggered manner is constructed by bringing the two trigger ends close to each other. At the stage where the deflection of the diamond wire does not need to be detected, the two trigger ends only need to be moved or rotated away from each other.

[0085] 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.
