Description

Technical Field

[0001] The utility model relates to the technical field of wire cutting, in particular to a wire-breaking remedial winding device for a wire cutting machine and the wire cutting machine. Background Art

[0002] In the field of online sawing technology, taking photovoltaic silicon ingots as an example, the process of converting ingots into wafers typically involves cutting, squaring, grinding, polishing, and slicing. Due to the high hardness of crystalline silicon, large-sized crystalline silicon is currently cut using cutting wires such as diamond wire. When cutting crystalline silicon, especially with multi-wire sawing equipment, severe wear or other anomalies in the wire can cause the wire to break, rendering it impossible to cut. Manual repair is required before further cutting can be resumed. Wire welding is a frequently used post-breakage treatment method that can significantly reduce losses. Wire break handlers clean the broken wire and sort out the broken wire ends on both sides. Using a wire bonder, they weld the two broken ends together and collect them onto the main roller for further processing. Specifically, the welded wire ends are relatively long and do not fit onto the main roller. Operators use pulleys to tighten the wire, slowly moving the wire, and gradually collect the wire ends onto the main roller so that they can rotate with the main roller like normal wire. The entire process requires experienced wire break handlers. Utility Model Content

[0049] like Figure 1 As shown, and reference Figures 2 to 7 , an embodiment of the present invention provides a wire breakage remedial take-up device 100. The wire breakage remedial take-up device 100 for a wire cutting machine includes a mounting frame 10, a transition wheel 20, a moving unit 30, and a flipping unit 40. The transition wheel 20 is provided with a wire groove for accommodating a cutting wire 300, which may be a steel wire. The moving unit 30 is mounted on the mounting frame 10. The transition wheel 20 is connected to the moving unit 30 so as to move driven by the moving unit 30. The flipping unit 40 is configured to drive the transition wheel 20 to flip so that the cutting wire 300 on the transition wheel 20 is detached from the transition wheel 20.

[0050] In an embodiment of the present invention, when the cutting line 300 is broken, the wire breakage processing personnel clean up the broken wire ends at the broken wire, sort out the broken wire ends on both sides, and use a wire welding machine to weld the two sorted broken wire ends together. According to the length of the cutting line 300 after welding, the transition wheel 20 is moved to a suitable position by the moving unit 30, and the welded cutting line 300 is put on the transition wheel 20. Then the main roller 200 of the cutting device starts to rotate, and the moving unit 30 is controlled to make the transition wheel 20 gradually approach the main roller 200. After the transition wheel 20 moves to the predetermined position, the flipping unit 40 is actuated to flip the transition wheel 20, and the cutting line 300 will be detached from the transition wheel 20, that is, the cutting line 300 falls off freely. Then, as the main roller 200 rotates, the welded cutting line 300 is reeled onto the main roller 200 to complete the wire reeling operation. In this embodiment, after the broken wire is welded and mounted on the transition wheel 20, the process can be automated, eliminating the need for manual intervention, and even more so, the need for experienced wire handling personnel. This allows employees to be kept away from the main roller 200, thereby protecting their safety and reducing labor costs. The wire retrieving and winding device 100 of the present invention can replace manual labor in winding the wire ends after cutting the broken wire onto the main roller 200, thereby improving wire recovery efficiency, improving the quality of silicon wafers after wire cutting, saving labor, and eliminating the need for experience in winding operations.

[0051] In some embodiments of the present invention, the wire breakage remediation take-up device 100 further includes a tension detection unit 50. The tension detection unit 50 is mounted on the mounting frame 10, and the tension detection unit 50 is configured to detect the tension of the cutting wire 300 on the transition wheel 20. During the take-up operation, the cutting wire 300 is tightened, applying a force to the tension detection unit 50, and feeding back information to the mobile unit. The mobile unit controls the mobile transition wheel 20 according to the received signal to ensure the stability of the tension of the cutting wire 300. In the embodiment of the present invention, the tension detection unit 50 is used to ensure that the cutting wire 300 received on the main roller 200 has a stable tension, thereby reducing abnormalities such as reduced quality of the rescued silicon wafers and increased rescue losses caused by abnormal tension, thereby having the advantages of improving the efficiency of wire breakage rescue, improving the quality of silicon wafers after wire cutting, and saving labor.

[0052] In some embodiments of the present invention, Figure 3As shown, the broken line remedial winding device 100 also includes a movable seat 31, and the movable seat 31 is connected to the movable unit 30. The flip unit 40 and the transition wheel 20 are both arranged on the movable seat 31. The mounting frame 10 includes a movable base 11, and the movable base 31 is movably mounted on the movable base 11. For example, a plurality of guide rods 12 are provided on the movable base 11, and a guide hole is provided on the movable base 31, and each guide rod 12 passes through a guide hole. In other embodiments of the present invention, a slide rail may be provided on the movable base 11, and the movable base 31 is provided on the slide rail. In other embodiments of the present invention, a slide rail is provided on the movable base 11, and the movable base 31 is provided on the slide rail; and a plurality of guide rods 12 are provided on the movable base 11, and a guide hole is provided on the movable base 31, and each guide rod 12 passes through a guide hole.

[0053] In the embodiment of the present invention, the flip unit 40 and the transition wheel 20 are both arranged on the flip unit 40, which is beneficial to the overall movement of the flip unit 40 and the transition wheel 20 and the flip unit 40 driving the transition wheel 20 to flip.

[0054] In some embodiments of the present invention, Figure 3 As shown, the turning unit 40 includes a turning frame 41 and a drive assembly. The turning frame 41 is rotatably mounted on the movable base 31. The transition wheel 20 is rotatably mounted on the turning frame 41. The drive assembly is configured to rotate the turning frame 41. The rotation axis of the turning frame 41 is perpendicular to the rotation axis of the transition wheel 20. In other embodiments of the present invention, the angle between the rotation axis of the turning frame 41 and the rotation axis of the transition wheel 20 is 60° to 90°.

[0055] In some embodiments of the present invention, the driving assembly includes a first driving portion 42 and a transmission mechanism, and the transmission mechanism is configured to transmit the output of the first driving portion 42 to the flip frame to drive the flip frame to rotate.

[0056] For example, in some embodiments of the present invention, the rotation axis of the flip frame 41 is arranged vertically. The flip frame 41 is a flip rod, which is rotatably mounted on the movable seat 31. The transition wheel 20 is rotatably mounted on one end of the flip rod around the flip rod. The first driving part 42 can be a motor or a servo, which has an output shaft for rotation. The transmission mechanism includes a crank 43 and a connecting rod 44. One end of the crank 43 is fixedly connected to the output shaft, one end of the connecting rod 44 is rotatably connected to one end of the crank 43, and the other end of the connecting rod 44 is rotatably connected to the other end of the flip rod. In this embodiment, the crank 43, the connecting rod 44 and the flip rod constitute a four-link 44 mechanism, which has a simple structure and stable movement, is conducive to keeping the transition wheel 20 in the current position, and is conducive to stably driving the transition wheel 20 to flip.

[0057] In some embodiments of the present invention, a limit switch is provided on the mobile base 11 to determine the position of the transition wheel 20. When the transition wheel 20 approaches the wire web, the limit switch on the mobile base 11 is triggered, the servo operates, pulling the connecting rod 44 backward, causing the transition wheel 20 to rotate 90 degrees. The walls of the wire groove of the transition wheel 20 no longer restrain the wire, allowing the wire to fall freely, completing the wire take-up operation. The wire web refers to the uniformly dense wire cutting area composed of the sequentially arranged wires wound around the main roller 200.

[0058] In some embodiments of the present invention, Figure 4 As shown, the tension detection unit 50 includes a tension arm 51 and a support wheel 52. One end of the tension arm 51 is mounted on the mobile base 11. The support wheel 52 is disposed at the other end of the tension arm 51 and is configured to support the cutting line 300. The support wheel 52 is disposed outside the cutting line 300. This prevents the cutting line 300 from being entangled by the support wheel 52 after it detaches from the transition wheel 20, facilitating its return to the main roller 200. The support wheel 52 is squeezed by the cutting line 300, which in turn squeezes the tension arm 51, facilitating tension detection.

[0059] In some embodiments of the present invention, the tension arm 51 is a tension sensing arm, one end of which is fixedly mounted on the mobile base 11, and a sensor is provided on the tension sensing arm. The sensor detects the deformation of the tension arm 51, thereby determining the extrusion force provided by the cutting line 300, and thus the tension of the cutting line 300. In some alternative embodiments of the present invention, one end of the tension arm 51 is rotatably mounted on the mobile base 11, an elastic device is provided between one end of the tension arm 51 and the mobile base 11, and a force detection device is provided between the elastic device and the tension arm 51 or between the elastic device and the mobile base 11. In this embodiment, the tension of the cutting line 300 is determined by detecting changes in the elastic device.

[0060] In some embodiments of the present invention, the wire breakage remedial take-up device 100 further includes an alarm unit, which is a light-emitting device and / or a sound-emitting device. The alarm unit is electrically connected to the tension detection unit 50 and is configured to issue an alarm based on the tension detected by the tension detection unit 50. The provision of the alarm unit facilitates intuitive determination of the tension of the cutting line 300, making it easier for employees to operate by observation.

[0061] In some embodiments of the present invention, Figures 3 to 5As shown, the mobile unit 30 includes a screw rod 32, which is rotatably mounted on the mobile base 11. The screw rod 32 can be a T-shaped screw rod. The mobile base 31 has a threaded hole that cooperates with the screw rod 32 so as to move along the screw rod 32 when the screw rod 32 rotates. The mobile unit 30 also includes a second drive portion 33 and / or a handwheel 34. The second drive portion 33 is configured to drive the screw rod 32 to rotate. The handwheel 34 is rotatably mounted on the mobile base 11 and is configured to drive the screw rod 32 to rotate through a transmission assembly. The second drive portion 33 can be a motor, and the transmission assembly can be a pulley transmission device 35.

[0062] In this embodiment, the handwheel 34 can drive the pulley transmission device 35 to control the T-type screw rod. After the wire is welded, the transition wheel 20 can be adjusted to a suitable position. The servo motor can control the rotation speed of the T-type screw rod 32 according to the actual tension detected by the tension detection unit 50 to ensure that the steel wire is retracted onto the main roller 200 under the required tension.

[0063] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the mounting frame 10 also includes a support frame, and the movable base 11 is in the shape of an elongated strip. The movable base 11 is rotatably mounted on the upper end of the support frame around a horizontal axis. For example, the movable base 11 can be rotated to a vertical state or a horizontal state. The rotatable setting of the movable base 11 facilitates adjustment of the angle of the movable base 11 and the distance between the movable base 11 and the machine platform, and is compatible with the use of various machine models. When not in use, the steel wire control body including the movable base 11, the mobile unit, the movable seat 31 and the flipping device can be placed vertically to reduce space occupancy and avoid accidental collision damage.

[0064] In some embodiments of the present invention, a locking device is provided between the support frame and the mobile base 11 to lock the mobile base 11 so that the mobile base 11 remains in its current position relative to the support frame. In other words, the provision of the locking device allows the mobile base 11 to be mounted on the support frame with adjustable angle and sufficient stability. The locking device may include a jackscrew that is threadedly connected to the support frame, disposed parallel to the rotation axis of the mobile base 11, and tightens against a rotating block fixedly connected to the mobile base 11 and mounted on the support frame.

[0065] In some embodiments of the present invention, the support frame includes a support base 13 and a lifting rod 14, and the lifting rod 14 is arranged vertically. The lifting rod 14 is mounted on the support base 13 so that its position can be adjusted in the height direction. The movable base 11 is arranged at the top of the lifting rod 14. By providing the lifting rod 14, multi-wire cutting equipment of cutting chambers of different heights can be compatible. For example, a socket is provided on the support base 13, and the lifting rod 14 is inserted into the socket. A top screw is provided on the support base 13, and the top screw is screwed into the support base and extends into the socket to press the lifting rod 14, thereby locking the lifting rod 14.

[0066] In some embodiments of the present invention, a roller assembly 60 is provided at the lower end of the mounting frame 10. The roller assembly 60 includes a roller and a brake device, wherein the brake device is configured to prevent the roller from rolling relative to the mounting frame 10. Specifically, the roller assembly 60 is provided on the support base 13. The support base 13 may also be referred to as a chassis. The roller assembly 60 is a wheel with brakes, which facilitates on-site mobility and ensures that the wire breakage remedial take-up device 100 can be freely moved to the multi-wire cutting equipment for wire winding operations. Each wheel has a good braking function, ensuring that the relative position of the wire breakage remedial take-up device 100 and the multi-wire cutting machine does not move during wire winding, which is conducive to improving the stability of wire winding.

[0067] When the wire-breaking remedial wire-taking device 100 for a wire cutting machine of the present invention is used, Figure 6 and Figure 7 As shown, after welding the wire ends, push the wire-breaking remedial winding device 100 to the wire cutting equipment that needs to be wound up, and adjust the position, height and angle (the position, height and angle of the same wire cutting equipment are consistent, and no adjustment is required each time). After the brake device brakes the roller, put the steel wire into the wheel groove of the transition wheel 20 and the support wheel 52, and use the hand wheel 34 to gradually tighten the steel wire so that the steel wire has and maintains a certain tension. When the tension sensing arm senses that the steel wire has reached the appropriate tension, the warning unit will light up and display. Then, the multi-wire cutting machine is operated to control the rotation of the main roller 200, and the steel wire is gradually wound onto the main roller 200. Because the tension of the new steel wire on the main roller 200 is greater than the steel wire to be wound, as more new wires are put out of the main roller 200, the tension of this section of steel wire to be wound becomes greater, and a force will be applied to the tension sensing arm and transmitted to the servo motor. The servo motor drives the moving seat 31 to move toward the main roller 200 to relieve the tension, and adjusts the speed at any time to keep the tension of the steel wire stable during the winding process. When the transition wheel 20 moves, it will trigger the limit switch and give a signal to the servo. The servo pulley pulls the connecting rod 44 backward at the set speed to flip the transition wheel 20 to unload the steel wire and complete the winding operation.

[0068] The wire breakage remediation and winding device 100 of the present invention can replace manual labor to wind up the welding wire ends after cutting the broken wires onto the main roller 200, and make the steel wire wound onto the main roller 200 have a stable tension, thereby reducing abnormalities such as the decline in the quality of the rescued silicon wafers and the increase in rescue losses caused by abnormal winding tension. It has the advantages of improving the efficiency of wire breakage rescue, improving the quality of silicon wafers after welding wire cutting, saving labor, and eliminating the need for experience in wire winding operations, and can be operated by operators without rich experience.

[0069] The embodiment of the present utility model also provides a wire cutting machine, which includes a cutting device and a wire breakage remedial winding device 100 in any of the above embodiments. The wire cutting machine is a cutting machine used for cutting hard and brittle material rods such as single crystal silicon material rods, polycrystalline silicon material rods, sapphire rods, magnetic material rods, etc. The wire cutting machine has the advantages of high efficiency, high production capacity, and high precision. Its principle is to achieve the purpose of cutting by rubbing the workpiece to be processed with a high-speed moving cutting wire 300. The wire cutting machine often uses single-wire or multi-wire cutting wires to cut, square, and slice silicon materials, etc., so as to obtain corresponding silicon wafers or silicon materials. The cutting device is used for cutting, and it has a main roller 200, a cutting wire 300 arranged on the main roller 200, and a lifting device for driving the workpiece to move up and down. The lifting device drives the workpiece to move downward, contacts the cutting wire, and is cut by the cutting wire. In this embodiment, the cutting line 300 on the cutting device is first placed on the transition wheel 20 after being disconnected and welded, and the rear flipping unit 40 drives the transition wheel 20 to flip so that the cutting line 300 on the transition wheel 20 is separated from the transition wheel 20, so that the cutting line 300 returns to the cutting device.

[0070] In some embodiments of the present invention, the wire saw is a slicer. It can slice silicon rods and the like. For example, crystalline silicon, the primary raw material for solar panels, requires processes such as squaring and slicing before it can be made into crystalline silicon wafers. The slicing process is performed using a slicer, which slices the squared silicon rods into silicon wafers.
