Abstract
Description

[0002] Wire cutting machine is an important equipment used to cut solar crystal rods into solar wafers. During the long-term cutting operation of the wire cutting machine, the wire is easy to break due to fatigue and aging. A wire break alarm device is required to immediately transmit the wire break signal to the wire cutting machine to stop the wire cutting machine to prevent the broken wire from being entangled in other wires and damaging the solar crystal rod.
[0003] The existing wire break alarm device mainly includes a metal rod installed in front of the winding wheel, and the metal rod is connected to the wire cutter control circuit. When the wire cutter's tangent breaks, the broken tangent falls on the metal rod under the action of inertia, causing the wire cutter control circuit to short-circuit, thereby automatically stopping the wire cutter. However, due to the harsh working environment of the wire cutter, the metal rod is stained with mortar used in solar wire cutting operations. The broken tangent cannot be connected to the metal rod when it reaches the metal rod, and the wire cutter control circuit cannot be short-circuited. When the tangent breaks, the wire cutter cannot stop automatically, and the alarm is not accurate. In normal wire cutting operations, water droplets on the tangent splashing on the metal rod will also cause the wire cutter control circuit to short-circuit, resulting in false alarms.

[0024] Reference below Figure 1-Figure 3 A wire saw 100 according to an embodiment of the present invention is described.
[0025] like Figure 1-Figure 3 As shown, the wire cutting machine 100 according to the embodiment of the utility model includes a housing 1, a winding main roller 2 and an alarm device 3.
[0026] Specifically, the housing 1 has a cutting chamber. The winding main roller 2 is arranged in the cutting chamber, and a tangent line 21 is wound on the winding main roller 2, and the tangent line 21 is used to cut the solar crystal rod. The alarm device 3 is arranged on one radial side of the winding main roller 2, and the alarm device 3 includes a pull wire, a shielding member 32 and a sensor 33. One end of the pull wire is fixed, and the other end of the pull wire is connected to the shielding member 32. The shielding member 32 is suitable for shielding the sensor 33. Among them, after the tangent line 21 breaks, the pull wire is cut off, the shielding member 32 falls off and separates from the sensor 33, the sensor 33 alarms, and the wire cutting machine 100 stops working.
[0027] For example, in Figure 1-Figure 3In the example, the winding main roller 2 is arranged along the length direction of the shell 1 (for example, Figure 1 The length direction of the winding main roller 2 (for example, Figure 1 The two ends of the wire cutting machine 100 (left and right directions in the drawing) are connected to the side walls of the shell 1. The tangent 21 is wound around the winding main roller 2 and extends in a direction away from the winding main roller 2. There are multiple tangents 21, and the multiple tangents 21 are evenly spaced along the length direction of the winding main roller 2. The alarm device 3 is arranged between one end of the winding main roller 2 in the length direction and the side wall of the shell 1. Among them, the sensor 33 is connected to the side wall of the shell 1, and the shielding member 32 is located on the side of the sensor 33 adjacent to the winding main roller 2. The shielding member 32 is pulled up by the pull wire so that the shielding member 32 shields the sensor 33. When the sensor 33 is blocked, the wire cutting machine 100 is in a normal working state, and the sensor 33 will not alarm. When the tangent wire 21 breaks, the tangent wire 21 will still move in the wire cutting machine 100 due to inertia and cut the pull wire. The pulling force of the pull wire on the shielding member 32 disappears, causing the shielding member 32 to fall. At this time, the shielding member 32 no longer blocks the sensor 33. The sensor 33 will immediately sound an alarm to remind the staff that the tangent wire 21 in the wire cutting machine 100 is broken, and the wire cutting machine 100 will stop working immediately to prevent the tangent wire 21 from causing damage to other components in the cutting room.
[0028] Therefore, by blocking and separating the sensor 33 through the shielding member 32 and controlling the alarm function of the sensor 33, an alarm can be given in time for the cutting and breaking situation inside the wire cutting machine 100, and the alarm signal is accurate, that is, when the alarm is given, the wire 21 must have been broken inside the wire cutting machine 100, which makes it convenient for the staff to repair the wire cutting machine 100 in time to prevent affecting the normal operation of production.
[0029] According to the wire cutting machine 100 of the embodiment of the utility model, an alarm device 3 is arranged in the cutting chamber of the wire cutting machine 100, and the shielding member 32 shields and separates the sensor 33, so as to control the sensor 33 to alarm. Therefore, compared with the traditional wire cutting machine, the wire cutting machine 100 can alarm in time when the cutting wire 21 is broken, and the alarm is accurate, so that the staff can replace the cutting wire 21 in time, thereby ensuring the normal operation of production.
[0030] According to some embodiments of the present invention, the wire cutting machine 100 further includes a mounting bracket 4 and at least one winding shaft 421. The mounting bracket 4 is disposed on the side of the sensor 33 facing the winding main roller 2, and the mounting bracket 4 is located above the sensor 33. The winding shaft 421 is disposed on the mounting bracket 4, and the wire is wound around the winding shaft 421 and connected to the shielding member 32. Figure 1-Figure 3The mounting bracket 4 is arranged on one side of the sensor 33 adjacent to the winding main roller 2, and the mounting bracket 4 is connected to the sensor 33. One end of the pull wire is wound on the winding shaft 421, and the other end of the pull wire is connected to the sensor 33, which facilitates the pull wire wound on the winding shaft 421 to pull up the shielding member 32, and the shielding member 32 shields the sensor 33, so that the pull wire is as close to the tangent line 21 as possible, ensuring that the pull wire can be cut off when the tangent line 21 breaks. In this way, the internal structure of the wire cutting machine 100 is reasonable, which can realize the alarm without hindering the normal operation of the wire cutting machine 100.
[0031] According to some embodiments of the present invention, the mounting bracket 4 and the shielding member 32 are located in a first direction of the sensor 33 (for example, Figure 1 The same side of the front-to-back direction. Figure 1-Figure 3 As shown, the width direction of the sensor 33 is the first direction. The mounting bracket 4 and the shielding member 32 are both located on the side of the sensor 33 adjacent to the winding main roller 2. The pull wire needs to bypass the winding shaft 421 located on the mounting bracket 4 and connect with the shielding member 32, that is, the pull wire is also located on the side of the sensor 33 adjacent to the winding main roller 2. In this way, it can be ensured that the shielding member 32 can shield the sensor 33, and when the cut wire 21 breaks, the cut wire 21 can cut the pull wire, so that the shielding member 32 can be separated from the sensor 33, and the sensor 33 can send out an alarm, so that the staff can promptly discover the broken wire condition of the wire cutting machine 100.
[0032] According to some embodiments of the present invention, the sensor 33 includes a main body 331 and a probe 332 connected to each other, the main body 331 is connected to the inner wall of the housing 1, the mounting bracket 4 is connected to the main body 331, and the probe 332 is located between the shielding member 32 and the main body 331. Figure 1-Figure 3 In the example, the probe 332 is arranged on one side of the main body 331 adjacent to the winding main roller 2. The mounting bracket 4 is arranged on one side of the main body 331 adjacent to the probe 332, and the probe 332 and the main body 331 are respectively located on both sides of the thickness direction of the mounting bracket 4. When the shielding member 32 is pulled up by the pull wire, the shielding member 32 shields the probe 332. When the probe 332 cannot sense the shielding member 32, a signal can be transmitted to the main body 331, so that the main body 331 sends an alarm. In this way, the arrangement of the alarm device 3 in the wire cutting machine 100 is reasonable, and the alarm device 3 can give an alarm in time, so that the staff can repair it in time.
[0033] According to some embodiments of the present invention, when the pull wire is not broken, the minimum distance between the shielding member 32 and the probe 332 in the first direction is L, where L satisfies: L≤5mm. Figure 1-Figure 3When the minimum distance between the probe 332 and the shielding member 32 in the first direction is greater than 5 mm, the distance between the probe 332 and the shielding member 32 is too far, and the shielding effect of the shielding member 32 on the probe 332 is not obvious enough, so that the sensor 33 is easy to fail to sense the shielding of the shielding member 32 and issue a false alarm. Therefore, when the minimum distance between the probe 332 and the shielding member 32 in the first direction is less than or equal to 5 mm, it is ensured that the probe 332 can sense the shielding of the shielding member 32, and the sensor 33 is prevented from issuing a false alarm. When the shielding member 32 is separated from the probe 332, the probe 332 can also sense the detachment of the shielding member 32 and issue an alarm in time. The alarm accuracy of the alarm device 3 is improved, so that the staff can promptly discover the breakage of the tangent 21 of the wire cutting machine 100 and replace the tangent 21 in time.
[0034] According to some embodiments of the present invention, the wire cutting machine 100 further includes a baffle 5, which is connected to the inner wall of the housing 1. The baffle 5 and the inner wall of the housing 1 together define an installation cavity, and the shielding member 32, the probe 332 and at least part of the main body 331 are located in the installation cavity. Figure 1-Figure 3 As shown, the baffle 5 is arranged above the sensor 33. By arranging the shielding member 32, the probe 332 and at least part of the main body 331 in the installation cavity, the shielding member 32, the probe 332 or the main body 331 is contaminated by the splash of mortar and liquid when the tangent line 21 is cut, and the probe 332 is prevented from being contaminated and affecting the sensing of the shielding member 32 by the probe 332, and pollutants are prevented from entering the sensor 33, so that the sensor 33 is prevented from being damaged, and the service life of the alarm device 3 is extended.
[0035] According to some embodiments of the present invention, a stopper 7 is provided on the inner wall of the baffle plate 5 on the side adjacent to the shielding member 32 in the first direction. The stopper 7 extends along the first direction and is located on the side adjacent to the mounting bracket 4 of the shielding member 32. Figure 1-Figure 3 In the example, the limit block 7 is located above the shielding member 32, and the limit block 7 abuts against the upper end of the baffle 5 and is fixedly connected to the baffle 5. When the pull wire pulls up the shielding member 32, the shielding member 32 can contact the limit block 7, and the limit block 7 abuts against the shielding member 32 to limit the shielding member 32, preventing the shielding member 32 from being pulled up too high, and also preventing the shielding member 32 from being pulled up too low, limiting the position of the shielding member 32 when it blocks the probe 332, and facilitating the operation of the staff. Therefore, by setting the limit block 7, it is ensured that the position of the shielding member 32 can completely block the probe 332, so that the alarm device 3 can work normally.
[0036] According to some embodiments of the present invention, the shielding member 32 is a non-uniform weight block. The wire cutting machine 100 further includes a connecting member 6, which is passed through the baffle 5, and the lighter end of the shielding member 32 is connected to one end of the connecting member 6, and the other end of the connecting member 6 is connected to the other end of the pull wire. Figure 3 , the shielding member 32 is arranged along the width direction of the housing 1 (for example, Figure 3 The shielding member 32 is divided into a first connecting section 321 and a second connecting section 322, and the first connecting section 321 and the second connecting section 322 are arranged along the width direction of the shell 1. The cross-section of the first connecting section 321 and the second connecting section 322 is in a T-shape. The heavier end of the shielding member 32 is the first connecting section 321, and the shape of the first connecting section 321 is a cube, and the lighter end of the shielding member 32 is the second connecting section 322, and the shape of the second connecting section 322 is a rectangular parallelepiped.
[0037] The connecting member 6 is connected to the second connecting section 322 to fix the second connecting section 322 on the baffle 5. A winding screw is connected to the first connecting section 321, and the winding screw is located on the side of the first connecting section 321 away from the probe 332. The pull wire is connected to the winding screw so that the shielding member 32 is pulled up and the sensor 33 is shielded. When the tangent 21 in the wire cutting machine 100 is broken, the broken tangent 21 cuts off the pull wire, causing the shielding member 32 to fall. At this time, the first connecting section 321 falls downward, and the second connecting section 322 rotates around the connecting member 6, thereby preventing the shielding member 32 from falling completely to the bottom of the shell 1, and facilitating the repair of the wire cutting machine 100. The shielding member 32 can be pulled up again, which is easy to operate and easy to repair, saving the maintenance time of the staff.
[0038] It should be noted that the pull wire can bear the weight of the shielding member 32 and the tension when the pull wire is tightened, and the wire cutting 21 can directly cut the pull wire.
[0039] According to some embodiments of the present invention, the mounting bracket 4 includes a first bracket segment 41 and a second bracket segment 42. One end of the first bracket segment 41 is connected to the sensor 33, and the first bracket segment 41 is arranged along the second direction (for example, Figure 2 The second bracket segment 42 is connected to the other end of the first bracket segment 41, and the second bracket segment 42 extends along the first direction. The second bracket segment 42 is provided with a winding shaft 421.
[0040] like Figure 1-Figure 3As shown, the first bracket section 41 is arranged between the body and the probe 332. The second bracket section 42 is connected to the end of the first bracket section 41 away from the sensor 33, and the second connecting section 322 extends in a direction away from the sensor 33. The winding shaft 421 is arranged on the second bracket section 42, and the winding shaft 421 extends along the height direction of the housing 1. In this way, the winding shaft 421 is located above the shielding member 32, so that the pull wire wound on the winding shaft 421 can pull up the shielding member 32, so that the shielding member 32 can shield the sensor 33, so as to control the alarm of the sensor 33.
[0041] According to some embodiments of the present invention, there are multiple winding shafts 421. In the description of the present invention, "multiple" means two or more. The multiple winding shafts 421 are spaced apart along the first direction. Figure 1-Figure 3 The plurality of winding shafts 421 may respectively use screws with fixed threads and screws with smooth surfaces, so that when the wire is wound around the plurality of winding shafts 421, the wire can be fixed and can slide, so that the wire can tighten the shielding member 32. Figure 1 As shown, the number of winding shafts 421 can be 2, wherein the winding shaft 421 on the side away from the shielding member 32 can be a screw with a fixed thread, and the winding shaft 421 on the side adjacent to the shielding member 32 can be a screw with a smooth surface. When the pull wire is wound, one end of the pull wire is first wound around the screw with a fixed thread, and then wound around the screw with a smooth surface, and the other end of the pull wire is connected to the shielding member 32, thereby, the pull wire can smoothly pull the shielding member 32, and the pull wire can be kept taut to avoid the tension of the pull wire gradually loosening, so as to ensure that the tangent line 21 can cut off the pull wire when the tangent line 21 breaks, so that the alarm device 3 can smoothly alarm.
