Abstract

This application relates to a cable alignment control method. A specific position on the I-beam reel is designated as the edge alignment judgment point. The edge alignment component can identify this judgment point. When the edge alignment component identifies the judgment point, the cable alignment guide wheel is positioned at a preset position. A linear coordinate system is established with the preset position as the origin, allowing the cable alignment guide wheel to move along the axial direction of the I-beam reel. The coordinates C corresponding to the edge alignment judgment point in the linear coordinate system are calculated. A first cable alignment endpoint A' and a second cable alignment endpoint B' are defined on the I-beam reel. The coordinates A and B corresponding to the first cable alignment endpoint A' in the linear coordinate system are calculated. When the cable alignment guide wheel moves to coordinates A or B, it can reverse its movement. This cable alignment control method solves the problem that manual edge alignment is difficult to guarantee accuracy, leading to inefficient production operations.

Description

Technical Field

[0001] This application relates to the field of wire cutting machine technology, and in particular to a wire routing control method. Background Technology

[0002] In the field of wire cutting machine technology, a wire cutting machine can transfer the cutting wire from the feed reel on one side of the cutting chamber to the main roller of the cutting chamber via a wire feeding device, and neatly wind the cutting wire onto the take-up reel on the other side of the cutting chamber. The wire feeding device is equipped with a wire feeding guide wheel, which moves along the axial direction of the reel to feed the cutting wire onto the take-up reel, or to retract the cutting wire from the take-up reel. Before the wire feeding device feeds the wire onto the reel, manual edge alignment is required. That is, before running the wire feeding, a safe distance is first set between the starting point of the winding on the winding reel and the inner edge of the reel. Then, the wire feeding guide wheel is moved, and the cutting wire is visually observed to determine whether it has moved to the starting point of the winding and whether it is perpendicular to the axis of the reel. Since the safe distance between the starting point of the winding and the inner edge of the reel is usually very small, it is difficult to guarantee the accuracy of manual edge alignment. Furthermore, each time a new I-beam is replaced, the edges need to be aligned again. The varying levels of worker proficiency result in unpredictable downtime for equipment changes, leading to inefficient production operations. Summary of the Invention

[0003] Therefore, it is necessary to provide a wiring control method to solve the problem that manual edge alignment is difficult to guarantee the accuracy of edge alignment and leads to inefficient operation of the production end.

[0004] A cable laying control method is provided, wherein the cable laying control method is executed by a cable laying device, the cable laying device includes a counter-side assembly and a cable laying guide wheel, and the counter-side assembly can follow the cable laying guide wheel to move along the axial direction of the I-beam wheel. The cable laying control method includes the following steps:

[0005] A certain position on the I-beam is set as the opposite edge judgment point C'. The opposite edge component can identify the opposite edge judgment point C'. When the opposite edge component identifies the opposite edge judgment point C', the cable guide wheel is defined to be at a preset position. With the preset position as the origin, a linear coordinate system is established for the cable guide wheel to move along the axial direction of the I-beam, and the coordinates C corresponding to the opposite edge judgment point C' in the linear coordinate system are calculated. A first cable endpoint A' and a second cable endpoint B' are set on the I-beam. When the opposite edge component identifies the opposite edge judgment point C', the cable guide wheel can move towards the direction closer to the first cable endpoint A' or the second cable endpoint B'. The coordinates A corresponding to the first cable endpoint A' in the linear coordinate system are calculated, and the coordinates B corresponding to the second cable endpoint B' in the linear coordinate system are calculated. When the cable guide wheel moves to coordinates A or B, the cable guide wheel can continue to move in the opposite direction.

[0006] In one embodiment, the opposite side component is a laser sensor, which can emit laser rays toward the I-beam to detect the distance from the surface of the I-beam to the laser emission point. The wiring control method further includes the following steps:

[0007] The distance between the opposite edge judgment point C' and the laser emission point is set to a preset distance value. When the laser sensor detects that the distance between the surface of the I-beam wheel and the laser emission point is equal to the preset distance value, the cable guide wheel moves towards the direction closer to the first cable endpoint A' or the second cable endpoint B'. It can be understood that this setting facilitates the opposite edge component to identify the opposite edge judgment point C'.

[0008] In one embodiment, the first inner edge of the I-beam is designated as the opposite edge determination point C', or the second inner edge of the I-beam is designated as the opposite edge determination point C'. It is understood that this design facilitates the laser sensor's identification of the opposite edge determination point C'.

[0009] In one embodiment, the laser beam emitted by the laser sensor is positioned parallel to the cutting line, or at an angle to the cutting line. It is understood that this arrangement facilitates the calculation of coordinate C.

[0010] In one embodiment, a laser sensor is disposed at one end of the cable guide wheel near the first inner edge of the I-beam. The laser ray emitted by the laser sensor is parallel to the cutting line, and the distance between the laser ray and the cutting line is l1. The distance between the first inner edge and the second inner edge of the I-beam is L. The distance between the first cable endpoint A' and the first inner edge of the I-beam is s1, and the distance between the second cable endpoint B' and the first inner edge of the I-beam is s2. The direction from near the preset position to near the first inner edge of the I-beam is defined as the positive direction of the linear coordinate system. When the first inner edge of the I-beam is taken as the opposite edge judgment point C', the coordinates of the first inner edge of the I-beam on the linear coordinate system are C = l1, A = l1 - s1, B = -|s2 - l1|. When the second inner edge of the I-beam is taken as the opposite edge judgment point C', the coordinates of the second inner edge of the I-beam on the linear coordinate system are C = l1, A = l1 + L - s1, B = l1 + L - s2. Understandably, this setup makes it easier to calculate coordinates A, B, and C.

[0011] In one embodiment, s1 < l1. It is understood that this setting helps to reduce the assembly difficulty of the laser sensor.

[0012] In one embodiment, l1 = 0. It is understood that this setting simplifies the calculation of coordinates A and B.

[0013] In one embodiment, the cable laying device further includes a drive assembly capable of driving the cable laying guide wheel to move axially along the I-beam wheel. The cable laying control method further includes the following steps:

[0014] The calculation and drive component drives the cable guide wheel from a preset position to the first stroke corresponding to coordinate A, and then drives it from the preset position to the second stroke corresponding to coordinate B. When the drive component reaches the first or second stroke, it drives the cable guide wheel to move in the opposite direction. This configuration allows the cable guide wheel to reciprocate between the first cable endpoint A' and the second cable endpoint B'.

[0015] In one embodiment, the driving component is a ribbon motor, and the ribbon control method further includes the following steps:

[0016] When the ribbon cable motor is at a preset position, its angle and number of revolutions are both 0. The first stroke is the first rotation angle and first revolution value corresponding to the ribbon cable guide wheel moving from the preset position to coordinate A. The second stroke is the second rotation angle and second revolution value corresponding to the ribbon cable guide wheel moving from the preset position to coordinate B. When the ribbon cable motor rotates to the first rotation angle and first revolution value, or when it rotates to the second rotation angle and second revolution value, the ribbon cable motor rotates in the opposite direction. This configuration helps reduce the calculation difficulty of the first rotation angle and first revolution value, as well as the second rotation angle and second revolution value, and allows the ribbon cable guide wheel to reverse direction promptly at the first ribbon cable endpoint A' or the second ribbon cable endpoint B'.

[0017] In one embodiment, the ribbon motor is a servo motor, which can record the angle and number of revolutions it has turned through through the encoder of the ribbon motor.

[0018] Since the opposite edge component can identify the opposite edge judgment point C' on the I-beam, and when the opposite edge component identifies the opposite edge judgment point C', the cable guide wheel can move towards the direction closer to the first cable endpoint A' or the second cable endpoint B'. Therefore, a linear coordinate system parallel to the axis of the I-beam can be established with the position of the cable guide wheel when the opposite edge component identifies the opposite edge judgment point C' as the origin. Normally, the cutting line on the I-beam is perpendicular to the axis of the I-beam. Therefore, when the opposite edge component identifies the opposite edge judgment point C', the four positions—the opposite edge component, the cable guide wheel, the opposite edge judgment point C', and the connection point of the cutting line on the I-beam—form the four endpoints of a rectangle or right trapezoid. Based on the distance between the opposite edge component and the cable guide wheel, and the positional relationship between the opposite edge component and the opposite edge judgment point C', the coordinate C of the opposite edge judgment point C' in the linear coordinate system can be calculated. Furthermore, based on the distance between the first line endpoint A' and the opposite side judgment point C' and the coordinate C, the coordinate A of the first line endpoint A' in the linear coordinate system is calculated, and based on the distance between the second line endpoint B' and the opposite side judgment point C' and the coordinate C, the coordinate B of the second line endpoint B' in the linear coordinate system is calculated.

[0019] By setting the opposite edge component and the opposite edge judgment point C', the opposite edge component and the opposite edge judgment point C' can work together to play a positioning role, which makes it easy to calculate the coordinates A of the first wire laying end point on the I-beam wheel in the linear coordinate system and the coordinates B of the second wire laying end point in the linear coordinate system. Combined with the fact that when the wire laying guide wheel moves to coordinates A or B, the wire laying guide wheel can continue to move in the opposite direction, it can be seen that the movement range of the wire laying guide wheel is accurately positioned between coordinates A and coordinates B.

[0020] Therefore, after replacing the new H-beam, you only need to move the cable guide wheel so that the opposite edge component recognizes the opposite edge judgment point C'. The cable guide wheel can then move toward coordinate A or coordinate B, and then move back and forth between coordinate A and coordinate B to lay the cable on the H-beam, without the need for manual edge alignment.

[0031] In the field of wire cutting machine technology, a wire cutting machine can transfer the cutting wire from the feed reel on one side of the cutting chamber to the main roller of the cutting chamber via a wire feeding device, and neatly wind the cutting wire onto the take-up reel on the other side of the cutting chamber. The wire feeding device is equipped with a wire feeding guide wheel, which moves along the axial direction of the reel to feed the cutting wire onto the take-up reel, or to retract the cutting wire from the take-up reel. Before the wire feeding device feeds the wire onto the reel, manual edge alignment is required. That is, before running the wire feeding, a safe distance is first set between the starting point of the winding on the winding reel and the inner edge of the reel. Then, the wire feeding guide wheel is moved, and the cutting wire is visually observed to determine whether it has moved to the starting point of the winding and whether it is perpendicular to the axis of the reel. Since the safe distance between the starting point of the winding and the inner edge of the reel is usually very small, it is difficult to guarantee the accuracy of manual edge alignment. Furthermore, each time a new I-beam is replaced, the edges need to be aligned again. The varying levels of worker proficiency result in unpredictable downtime for equipment changes, leading to inefficient production operations.

[0032] Please see Figures 1-3 To address the problem that manual edge alignment is insufficient to guarantee accuracy and leads to inefficient production, this application provides a cable routing control method. The method is executed by a cable routing device, which includes an edge alignment component and a cable routing guide wheel. The edge alignment component can follow the cable routing guide wheel along the axial direction of the I-beam. The cable routing control method includes the following steps:

[0033] A certain position on the I-beam 1 is designated as the opposite edge judgment point C'. The opposite edge component can identify the opposite edge judgment point C'. When the opposite edge component identifies the opposite edge judgment point C', the cable guide wheel 3 is positioned at a preset position 5. A linear coordinate system is established with the preset position 5 as the origin, allowing the cable guide wheel 3 to move along the axial direction of the I-beam 1. The coordinates C corresponding to the opposite edge judgment point C' in the linear coordinate system are calculated. A first cable endpoint A' and a second cable endpoint B' are defined on the I-beam 1. When the opposite edge component identifies the opposite edge judgment point C', the cable guide wheel 3 can move towards either the first cable endpoint A' or the second cable endpoint B'. The coordinates A corresponding to the first cable endpoint A' in the linear coordinate system and B corresponding to the second cable endpoint B' in the linear coordinate system are calculated. When the cable guide wheel 3 moves to coordinates A or B, it can continue moving in the opposite direction.

[0034] Since the opposite edge component can identify the opposite edge judgment point C' on the I-beam 1, and when the opposite edge component identifies the opposite edge judgment point C', the cable guide wheel 3 can move towards the direction closer to the first cable endpoint A' or the second cable endpoint B'. Therefore, a linear coordinate system parallel to the axis of the I-beam 1 can be established with the position of the cable guide wheel 3 when the opposite edge component identifies the opposite edge judgment point C' as the origin. Normally, the cutting line 4 on the I-beam 1 is perpendicular to the axis of the I-beam 1. Therefore, when the opposite edge component identifies the opposite edge judgment point C', the four positions of the opposite edge component, the cable guide wheel 3, the opposite edge judgment point C', and the connection point of the cutting line 4 on the I-beam 1 form the four endpoints of a rectangle or a right trapezoid. Based on the distance between the opposite edge component and the cable guide wheel 3 and the positional relationship between the opposite edge component and the opposite edge judgment point C', the coordinate C of the opposite edge judgment point C' on the linear coordinate system can be calculated. Furthermore, based on the distance between the first line endpoint A' and the opposite side judgment point C' and the coordinate C, the coordinate A of the first line endpoint A' in the linear coordinate system is calculated, and based on the distance between the second line endpoint B' and the opposite side judgment point C' and the coordinate C, the coordinate B of the second line endpoint B' in the linear coordinate system is calculated.

[0035] By setting the opposite edge component and the opposite edge judgment point C', the opposite edge component and the opposite edge judgment point C' can work together to play a positioning role, thereby making it easier to calculate the coordinate A of the first wire laying endpoint A' on the linear coordinate system and the coordinate B of the second wire laying endpoint B' on the linear coordinate system. Combined with the fact that the wire laying guide wheel 3 can continue to move in the opposite direction when it moves to coordinate A or coordinate B, it can be seen that the movement range of the wire laying guide wheel 3 is accurately positioned between coordinate A and coordinate B.

[0036] Therefore, after replacing the new H-beam 1, it is only necessary to move the cable guide wheel 3 so that the opposite side component can identify the opposite side judgment point C'. The cable guide wheel 3 can then move towards coordinate A or coordinate B, and then move back and forth between coordinate A and coordinate B to lay the cable on the H-beam 1, without the need for manual edge alignment.

[0037] In one embodiment, such as Figures 1-3 As shown, the opposite component is a laser sensor 2. The laser sensor 2 can emit a laser beam 21 towards the I-beam 1 to detect the distance from the surface of the I-beam 1 to the laser emission point. The wiring control method also includes the following steps:

[0038] The distance between the opposite edge judgment point C' and the laser emission point is set to a preset distance value. When the laser sensor 2 detects that the distance between the surface of the I-beam wheel 1 and the laser emission point is equal to the preset distance value, the cable guide wheel 3 moves toward the direction close to the first cable endpoint A' or the second cable endpoint B'.

[0039] Since the laser sensor 2 can emit a laser beam 21 towards the I-beam 1 to detect the distance from the surface of the I-beam 1 to the laser emission point, by setting the distance from the opposite edge judgment point C' to the laser emission point as a preset distance value, when the laser sensor 2 detects that the distance from the surface of the I-beam 1 to the laser emission point is equal to the preset distance value, it indicates that the laser irradiation point is located at the opposite edge judgment point C'. This facilitates the laser sensor 2 in identifying the opposite edge judgment point C'.

[0040] Furthermore, when the laser sensor 2 detects that the distance between the surface of the I-beam 1 and the laser emission point is equal to the preset distance value, the laser sensor 2 sends a signal to the controller, and the controller controls the movement toward the direction of the first cable endpoint A' or the second cable endpoint B' to start the cable laying operation.

[0041] Furthermore, in one embodiment, the first inner edge 11 of the I-beam is set as the opposite edge judgment point C', or the second inner edge 12 of the I-beam is set as the opposite edge judgment point C'.

[0042] There is a height abrupt change from the first inner edge 11 of the I-beam to the winding wheel in the middle of the I-beam 1. Combined with the fact that the laser sensor 2 can emit a laser beam 21 towards the I-beam 1 to detect the distance from the surface of the I-beam 1 to the laser emission point, it can be seen that setting the first inner edge 11 of the I-beam 1 or the second inner edge of the I-beam 1 as the opposite edge judgment point C' is beneficial for the laser sensor 2 to identify the opposite edge judgment point C' based on the detected abrupt change in the distance from the surface of the I-beam 1 to the laser emission point.

[0043] However, this is not the only one. In other embodiments, the opposite edge component can also be a mechanical contact sensor, which can identify the opposite edge judgment point C' by contacting the opposite edge judgment point C'.

[0044] In one embodiment, the laser beam 21 emitted by the laser sensor 2 is arranged parallel to the cutting line 4, or the laser beam 21 emitted by the laser sensor 2 is arranged at an angle to the cutting line 4.

[0045] like Figure 1 As shown, under normal circumstances, the extension direction of the cutting line 4 is perpendicular to the axial direction of the I-beam wheel 1. Therefore, when the laser ray 21 emitted by the laser sensor 2 is set parallel to the cutting line 4, the distance between the opposite side judgment point C' and the connection point of the cutting line 4 on the I-beam wheel 1 is equal to the distance between the laser ray 21 and the cutting line 4. Specifically, if the distance between the laser ray 21 and the cutting line 4 is l1, then |C| = l1.

[0046] like Figure 2As shown, when the laser ray 21 emitted by the laser sensor 2 forms an angle with the cutting line 4, the coordinate C can also be calculated based on the angle between the laser ray 21 and the cutting line 4. Specifically, the laser sensor 2 detects the distance M from the surface of the I-beam wheel 1 to the laser emission point, the distance l1 between the cable guide wheel 3 and the laser sensor 2, and the angle α between the laser ray 21 and the cutting line 4, |C| = l1 + Msina. Typically, the value of angle α is approximately 0, meaning the value of sinina is also approximately 0.

[0047] In one embodiment, such as Figure 1 and Figure 3 As shown, the laser sensor 2 is located at one end of the cable guide wheel 3 near the first inner edge 11 of the I-beam. The laser beam 21 emitted by the laser sensor 2 is parallel to the cutting line 4 between the I-beam and the cable guide wheel 3, and the distance between the laser beam 21 and the cutting line 4 is l1. The distance between the first inner edge 11 and the second inner edge 12 of the I-beam is L. The distance between the first cable endpoint A' and the first inner edge 11 of the I-beam is s1, and the distance between the second cable endpoint B' and the first inner edge 11 of the I-beam is s1. The distance s2 is defined as the positive direction from the direction near the preset position 5 to the direction near the first inner edge 11 of the I-beam wheel. When the first inner edge 11 of the I-beam wheel is taken as the opposite side judgment point C', the coordinates of the first inner edge on the linear coordinate system are C = l1, A = |l1-s1|, B = -|s2-l1|. When the second inner edge of the I-beam wheel 1 is taken as the opposite side judgment point C', the coordinates of the second inner edge on the linear coordinate system are C = l1, A = l1+L-s1, B = l1+L-s2.

[0048] In this embodiment, the one-way travel N of the cable guide wheel is N = s2 - s1. This facilitates the calculation of coordinates A, B, and C.

[0049] However, this is not the only embodiment. In other embodiments, the laser sensor 2 may be located at one end of the cable guide wheel 3 near the second inner edge 12 of the I-beam wheel.

[0050] Furthermore, in one embodiment, s1 < l1.

[0051] When the first inner edge 11 of the I-beam is taken as the opposite side judgment point C', since the distance s1 between the first wiring end point A' and the first inner edge 11 of the I-beam is usually small, setting s1 < l1 helps to reduce the assembly difficulty of the laser sensor 2.

[0052] In one embodiment, l1 = 0.

[0053] Thus, the laser beam 21 emitted by the laser sensor 2 coincides with the cutting line 4 along the radial direction of the I-beam 1. When the first inner edge 11 of the I-beam is taken as the opposite side judgment point C', C = 0, A = -s1, B = -s2; when the second inner edge of the I-beam 1 is taken as the opposite side judgment point C', C = 0, A = L -s1, B = L -s2.

[0054] This simplifies the calculation of coordinates A and B.

[0055] However, this is not the only possibility; in other embodiments, l1 ≠ 0.

[0056] In one embodiment, s2 = L - s1.

[0057] In this way, the distance between the starting point of the cable and the first inner edge 11 of the I-beam is equal to the distance between the ending point of the cable and the second inner edge 12 of the I-beam, that is, the cutting line 4 can maintain the same safe distance from the inner sides of both ends of the I-beam 1.

[0058] In one embodiment, the cable laying device further includes a drive assembly, which is capable of driving the cable laying guide wheel 3 to move along the axial direction of the I-beam wheel 1. The specific method by which the drive assembly drives the cable laying guide wheel 3 to move is as follows:

[0059] The calculation drive component drives the cable guide wheel 3 to move from the preset position 5 to the first stroke corresponding to coordinate A, and the calculation drive component drives the cable guide wheel 3 to move from the preset position 5 to the second stroke corresponding to coordinate B. When the drive component moves to the first stroke or the second stroke, the drive component drives the cable guide wheel 3 to move in the opposite direction.

[0060] Since the preset position 5 is the origin of the linear coordinate system, and A is the coordinate of the first cable endpoint A' in the linear coordinate system, it can be known that |A| is equal to the straight-line distance from the preset position 5 to the first cable endpoint A'. Based on this straight-line distance, the first stroke required for the drive component to run can be calculated.

[0061] Similarly, since the preset position 5 is the origin of the linear coordinate system, and B is the coordinate of the second cable endpoint B' in the linear coordinate system, it can be known that |B| is equal to the straight-line distance of the cable guide wheel 3 from the preset position 5 to the first cable endpoint B'. Based on this straight-line distance, the second stroke that the drive component needs to run can be calculated.

[0062] Furthermore, when the drive component reaches the first or second stroke, it drives the cable guide wheel 3 to move in the opposite direction, enabling the cable guide wheel 3 to reciprocate between the first cable endpoint A' and the second cable endpoint B'.

[0063] Furthermore, in one embodiment, the driving component is a ribbon cable motor, and the method for calculating the first stroke and the second stroke is as follows:

[0064] When the ribbon cable motor is located at a preset position 5, the angle value and number of revolutions of the ribbon cable motor are 0. The first stroke is the first rotation angle and the first revolution value corresponding to the ribbon cable guide wheel 3 moving from the preset position 5 to coordinate A. The second stroke is the second rotation angle and the second revolution value corresponding to the ribbon cable guide wheel 3 moving from the preset position 5 to coordinate B. When the motor rotates to the first rotation angle and the first revolution value, or when the motor rotates to the second rotation angle and the second revolution value, the ribbon cable motor rotates in the opposite direction.

[0065] When a ribbon cable motor drives the ribbon cable guide wheel 3, the ribbon cable guide wheel 3 is usually directly or indirectly connected to the output shaft of the ribbon cable motor. Therefore, for every fixed angle and number of revolutions the ribbon cable motor rotates, the ribbon cable guide wheel 3 moves a corresponding distance. Thus, the first stroke is the first rotation angle and first revolution value corresponding to the ribbon cable guide wheel 3 moving from the preset position 5 to coordinate A, and the second stroke is the second rotation angle and second revolution value corresponding to the ribbon cable guide wheel 3 moving from the preset position 5 to coordinate B. Furthermore, by setting the angle value and number of revolutions of the ribbon cable motor to 0 at this point, the calculation difficulty of the first rotation angle, first revolution value, and second rotation angle and second revolution value is reduced. Even further, when the ribbon cable motor rotates to the first rotation angle and first revolution value, or when the ribbon cable motor rotates to the second rotation angle and second revolution value, the controller controls the ribbon cable guide wheel 3 to reverse direction, thereby enabling the ribbon cable guide wheel 3 to reverse direction in a timely manner at the first ribbon cable endpoint A' or the second ribbon cable endpoint B'.

[0066] However, this is not the only option. In other embodiments, the cable guide wheel 3 can be driven to move along the axial direction of the I-beam wheel 1 by a cylinder or electric cylinder, and the travel of the cylinder or electric cylinder can be calculated according to |A| and |B| respectively.

[0067] Furthermore, in one embodiment, the ribbon motor is a servo motor, and the ribbon motor can record the angle it has rotated through through its encoder.

[0068] To ensure the cutting quality of a wire cutter, the tension of the cutting wire must be maintained within a reasonable range. This is typically achieved by using a tension sensor to detect the wire tension. When the tension sensor detects that the wire tension is outside the reasonable range, a correction mechanism is triggered. This involves the wire guide roller stopping at a specific position on the I-beam, and the correction mechanism adjusts the wire tension until it returns to the reasonable range. However, if the tension sensor malfunctions, false correction may occur. False correction means that the wire guide roller remains stationary at one of the two ends of the I-beam. Theoretically, this could lead to a break in the cutting wire. Because the I-beam is constantly winding and unwinding the wire, the actual displacement of the steel wire is ongoing, causing continuous changes in the wire tension. This can result in abnormal cutting quality from the wire cutter.

[0069] The wiring control method provided in this application can also detect whether incorrect correction has occurred during the operation of the wire cutting machine. The specific method is as follows:

[0070] The cable guide wheel 3 can reciprocate along the axis of the I-beam wheel 1, and the one-way stroke of the cable guide wheel 3 along the axis of the I-beam wheel 1 is N. Specifically, it includes the following steps:

[0071] Set a standard time T1 for the cable guide wheel 3 to complete a loop path of length kN along the axial direction of the I-beam wheel 1. Set a preset duration T2 as the pause time required for normal correction during the process of the cable guide wheel 3 completing a loop path of length kN along the axial direction of the I-beam wheel 1. Add the preset duration T2 to the standard time T1 to obtain the alarm time T3. Record the action time T used by the cable guide wheel 3 to complete a loop path of length kN along the axial direction of the I-beam wheel 1. Determine the magnitude of the action time T and the alarm time T3. If the action time T is greater than the alarm time T3, the alarm device will sound an alarm.

[0072] It should be noted that the preset duration T2 is a time range derived from experience. Since T3 = T1 + T2, T3 is also a time range. T greater than T3 means that T is greater than the maximum value of this time range.

[0073] Furthermore, it should be noted that k is a natural number that is not equal to 0.

[0074] Since T1 is the standard time for the cable guide wheel 3 to complete a kN loop along the axial direction of the I-beam wheel 1, and since the preset duration T2 is the pause time required for normal correction during the process of the cable guide wheel 3 completing a kN loop along the axial direction of the I-beam wheel 1, and since T3 = T1 + T2, the alarm time T3 is the normal time range for the cable guide wheel 3 to complete a kN loop along the axial direction of the I-beam wheel 1 under normal working conditions. If the action time T of the cable guide wheel 3 to complete a kN loop along the axial direction of the I-beam wheel 1 is greater than the alarm time T3, it indicates that a false correction has occurred within this kN loop. At this time, the alarm device will sound, and the staff can shut down the equipment in time based on the alarm sound to troubleshoot the wire cutting machine.

[0075] In one embodiment, such as Figure 1 As shown, the laser sensor 2 can emit a laser beam 21 towards the I-beam 1 to detect the distance from the surface of the I-beam 1 to the laser emission point. The process also includes the following steps:

[0076] A certain position on the I-beam 1 is set as the opposite side judgment point C', and the distance from the opposite side judgment point C' to the laser emission point is set as a preset distance value. When the laser sensor 2 detects that the distance from the surface of the I-beam 1 to the laser emission point is equal to the preset distance value, the timing starts.

[0077] Since laser sensor 2 emits laser beam 21 towards the I-beam 1 to detect the distance from the surface of the I-beam 1 to the laser emission point, by setting the distance from the opposite edge judgment point C' to the laser emission point as a preset distance value, when laser sensor 2 detects that the distance from the surface of the I-beam 1 to the laser emission point is equal to the preset distance value, it indicates that the laser irradiation point is located at the opposite edge judgment point C'. Furthermore, when laser sensor 2 detects that the distance from the surface of the I-beam 1 to the laser emission point is equal to the preset distance value, timing begins. In this way, laser sensor 2 can cooperate with the opposite edge judgment point C' to perform positioning and identification functions, facilitating the recording of action time T.

[0078] However, this is not the only option. In other embodiments, a mechanical contact sensor can be used in conjunction with the opposite edge judgment point C' to achieve the function of positioning and identification.

[0079] Furthermore, in one embodiment, as Figure 2 and Figure 3 As shown, the first inner edge 11 or the second inner edge 12 of the I-beam wheel is set as the opposite edge judgment point C'.

[0080] There is a height abrupt change from the first inner edge 11 or the second inner edge 12 of the I-beam to the winding wheel in the middle of the I-beam 1. Combined with the fact that the laser sensor 2 can emit a laser beam 21 to the I-beam 1 to detect the distance from the surface of the I-beam 1 to the laser emission point, it can be seen that setting the first inner edge 11 or the second inner edge 12 of the I-beam 1 as the opposite edge judgment point C' is beneficial for the laser sensor 2 to identify the opposite edge judgment point C' based on the detected abrupt change in the distance from the surface of the I-beam 1 to the laser emission point.

[0081] Furthermore, in one embodiment, k=2, and the preset duration T2 is the pause time required for the guide wheel 3 to complete a 2N-length cyclic path along the axis of the I-beam wheel 1 during normal correction. The method also includes the following steps: recording the time T6 taken for the laser ray 21 of the laser sensor 2 to irradiate the opposite side judgment point C' twice consecutively, where T=T6.

[0082] Since the timing starts when the laser sensor 2 detects that the distance from the surface of the I-beam wheel 1 to the laser emission point is equal to the preset distance value, and since the unidirectional stroke of the cable guide wheel 3 along the axial direction of the I-beam wheel 1 is N, the laser ray 21 of the laser sensor 2 illuminates the opposite side judgment point C' twice in succession, indicating that the cable guide wheel 3 has completed a loop path of length 2N along the axial direction of the I-beam wheel 1. That is, the time T6 = T is taken for the laser ray 21 of the laser sensor 2 to illuminate the opposite side judgment point C' twice in succession.

[0083] In this way, every time the wire guide wheel 3 completes a 2N-length cycle path along the axis of the I-beam wheel 1, it can detect whether there is any misalignment during the process, which is conducive to timely detection of whether the wire cutter has misalignment.

[0084] Furthermore, in one embodiment, a second preset time value T4 is set, and the time taken for the laser ray 21 of the laser sensor 2 to irradiate the opposite edge judgment point C' on two consecutive occasions is continuously recorded. calculate and The absolute value of the difference, |△|, if |△| > T4, the alarm device will sound an alarm.

[0085] It should be noted that the second preset time value T4 is a time range, and |△| > T4 means that |△| is greater than the maximum value of this time range.

[0086] Under normal operating conditions of the tension sensor, the action time T6 required for the cable guide wheel 3 to complete a 2N-length loop along the axial direction of the I-beam wheel 1 has a normal time range. Therefore, the time taken for the laser beam 21 of the laser sensor 2 to irradiate the opposite side judgment point C' between two consecutive occurrences is continuously recorded. but and The absolute value of the difference, Δ, should also have a normal range. By setting a second preset time value T4, if Δ is greater than T4, it indicates that a miscorrection has occurred.

[0087] Thus, in addition to detecting whether miscorrection occurs within each loop path of length 2N, an extra detection procedure is added, which helps to improve reliability.

[0088] In one embodiment, the wiring is performed by a wiring device, which includes a wiring guide wheel 3, a controller, a timer assembly, a drive assembly, and a counter-side assembly. The wiring guide wheel 3, the counter-side assembly, the timer assembly, and the drive assembly are electrically connected to the controller. The drive assembly can drive the wiring guide wheel 3 to reciprocate along the axial direction of the I-beam wheel 1. The counter-side assembly can send a preset signal to the controller so that the controller controls the timer assembly to start timing. The preset signal refers to the signal sent to the controller by the counter-side assembly when it identifies the counter-side judgment point C' of the I-beam wheel 1.

[0089] In one embodiment, if the action time T is greater than the alarm time T3, the controller controls the drive component to stop running and controls the I-beam 1 to stop winding and unwinding.

[0090] This makes it easier to shut down the equipment in a timely manner to troubleshoot the wire cutting machine malfunction.

[0091] In one embodiment, the driving component is a servo motor, and the controller records the action time T through the servo motor.

[0092] However, this is not the only one; in other embodiments, the drive component may also be a cylinder or an electric cylinder, etc.

[0093] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0094] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
