Description

Technical Field

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

[0002] In the field of wire cutting machine technology, a wire cutter 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 feed reel to feed the cutting wire to the take-up reel, or to retract the cutting wire from the take-up reel. To ensure the cutting quality of the wire cutter, the tension value of the cutting wire needs to be maintained within a reasonable range. Typically, a tension sensor is used to detect the tension of the cutting wire. When the tension sensor detects that the tension value of the cutting wire is outside the reasonable tension range, a correction mechanism is triggered. That is, the feed guide wheel stops at a certain position on the feed reel, and the correction mechanism corrects the cutting wire until the cutting wire returns to the reasonable tension range. However, when the tension sensor fails, false correction may occur. False correction means that the wire guide wheel stays at a certain position between the two ends of the I-beam. If the wire guide wheel stays at this position for too long, under theoretical limits, the cutting wire may not break. Since the I-beam is constantly taking in and releasing the wire, the actual displacement of the steel wire is constantly in progress, which causes the tension of the cutting wire to change continuously. This will lead to abnormal cutting quality of the wire cutter. Summary of the Invention

[0003] Therefore, it is necessary to provide a method for detecting incorrect alignment in order to detect whether incorrect alignment occurs in the wire cutting machine.

[0004] A method for detecting incorrect alignment, wherein a cable guide wheel can reciprocate along the axial direction of an H-beam, and the one-way stroke of the cable guide wheel along the axial direction of the H-beam is N, the method for detecting incorrect alignment includes the following steps:

[0005] Set the standard time T1 for the cable guide wheel to complete a loop path of length kN along the axial direction of the I-beam wheel. Set the preset duration T2 as the pause time required for normal correction during the process of the cable guide wheel completing a loop path of length kN along the axial direction of the I-beam wheel. Calculate the alarm time T3 = T1 + T2. Record the action time T for the cable guide wheel to complete a loop path of length kN along the axial direction of the I-beam wheel. 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.

[0006] In one embodiment, the laser sensor 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 error correction detection method further includes the following steps:

[0007] A specific position on the I-beam wheel is designated as the opposite edge detection point, and the distance between this point and the laser emission point is set to a preset distance value. Timing begins when the laser sensor detects that the distance between the I-beam wheel surface and the laser emission point equals the preset distance value. This allows the laser sensor to work in conjunction with the opposite edge detection point for positioning and identification, facilitating the recording of the action time T.

[0008] In one embodiment, k=2, and the preset duration T2 is the pause time required for normal correction during the process of the cable guide wheel completing a 2N-length loop path along the axial direction of the I-beam. The false correction detection method further includes the following step: recording the time T6 taken for the laser beam from the laser sensor to irradiate the opposite edge judgment point twice consecutively, where T=T6. It can be understood that with this setting, every time the cable guide wheel completes a 2N-length loop path along the axial direction of the I-beam, it can detect whether false correction has occurred, thus facilitating timely detection of whether the wire cutting machine has experienced false correction.

[0009] In one embodiment, the error correction detection method further includes the following steps:

[0010] Set a second preset time value T4, and continuously record the time taken for the laser ray from the laser sensor to hit the opposite edge judgment point in two consecutive instances. calculate and The absolute value of the difference, |Δ|, is taken. If |Δ| > T4, the alarm device will sound an alarm. It is understandable that, based on detecting whether false corrections occur within each loop path of length 2N, an additional detection procedure is added, thereby improving the reliability of the false correction detection method.

[0011] In one embodiment, either the first inner edge or the second inner edge of the I-beam is designated as the opposite edge determination point. It is understood that this design facilitates the laser sensor in identifying the opposite edge determination point based on the detected abrupt change in the distance between the I-beam surface and the laser emission point.

[0012] In one embodiment, k=1, and the preset duration T2 is the pause time required for normal correction during the process of the cable guide wheel completing a single path of length N along the axial direction of the I-beam wheel. The method for detecting incorrect correction further includes the following steps:

[0013] Two proximity switches are respectively installed at both ends of the wire guide wheel. The sensing length of the proximity switches is set. When the distance between the wire guide wheel and either the first or second inner edge of the I-beam is equal to the sensing length of the proximity switch, the wire guide wheel can move in the opposite direction. Timing begins when the distance between the wire guide wheel and either the first or second inner edge of the I-beam is equal to the sensing length of the proximity switch, and the time t taken for the wire guide wheel to move from one end of the I-beam to the other is recorded, where T = t. It can be understood that with this setup, every time the wire guide wheel completes a loop path of length N along the I-beam axis, it can detect whether there is any misalignment during the process, thus facilitating timely detection of misalignment in the wire cutting machine.

[0014] In one embodiment, the error correction detection method further includes the following steps:

[0015] Set a third preset time value T5, and continuously record the time t1, t2, t3...t taken for the cable guide wheel to move from one end of the I-beam wheel to the other. n-1 t n Calculate t n With t n-1 The absolute value of the difference, |Δ|, is taken. If |Δ| > T5, the alarm device will sound an alarm. It is understandable that, in addition to detecting whether false corrections occur within each loop path of length N, an extra detection step is added, which helps improve the reliability of the false correction detection method.

[0016] In one embodiment, the error correction detection method is performed by a cable laying device, which includes a cable laying guide wheel, a controller, a timer assembly, a drive assembly, and a counter-side assembly. The cable laying guide wheel, the counter-side assembly, the timer assembly, and the drive assembly are electrically connected to the controller. The drive assembly can drive the cable laying guide wheel to reciprocate along the axis of the I-beam. 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 a specific position on the I-beam.

[0017] In one embodiment, if the action time T is greater than the alarm time T3, the controller controls the drive component to stop operating and controls the I-beam reel to stop winding and unwinding the wire. It is understood that this configuration facilitates timely shutdown of the equipment to troubleshoot wire cutter malfunctions.

[0018] In one embodiment, the driving component is a servo motor, and the controller records the action time T through the servo motor.

[0019] Since T1 is the standard time taken for the cable guide wheel to complete a kN loop along the axial direction of the I-beam, and since the preset duration T2 is the pause time required for normal correction during the completion of the kN loop along the axial direction of the I-beam, and since T3 = T1 + T2, the alarm time T3 is the normal time range taken for the cable guide wheel to complete a kN loop along the axial direction of the I-beam under normal working conditions. If the action time T taken for the cable guide wheel to complete a kN loop along the axial direction of the I-beam 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. Attached Figure Description

[0030] In the field of wire cutting machine technology, a wire cutter 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 feed reel to feed the cutting wire to the take-up reel, or to retract the cutting wire from the take-up reel. To ensure the cutting quality of the wire cutter, the tension value of the cutting wire needs to be maintained within a reasonable range. Typically, a tension sensor is used to detect the tension of the cutting wire. When the tension sensor detects that the tension value of the cutting wire is outside the reasonable tension range, a correction mechanism is triggered. That is, the feed guide wheel stops at a certain position on the feed reel, and the correction mechanism corrects the cutting wire until the cutting wire returns to the reasonable tension range. However, when the tension sensor fails, false correction may occur. False correction means that the wire guide wheel stays at a certain position between the two ends of the I-beam. Under theoretical limits, there is a possibility that the cutting wire may not break. Since the I-beam is constantly taking in and releasing the wire, the actual displacement of the steel wire is in progress, which causes the tension of the cutting wire to change continuously. This will lead to abnormal cutting quality of the wire cutter.

[0031] In order to detect whether false correction occurs during the operation of a wire cutting machine, this application provides a method for detecting false correction.

[0032] 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. The error correction detection method includes the following steps:

[0033] 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.

[0034] 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.

[0035] Furthermore, it should be noted that k is a natural number that is not equal to 0.

[0036] 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.

[0037] 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 error correction detection method further includes the following steps:

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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'.

[0042] 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.

[0043] 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 loop path along the axial direction of the I-beam wheel 1 during normal correction. The error correction detection 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.

[0044] 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.

[0045] 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.

[0046] Furthermore, in one embodiment, the error correction detection method further includes the following steps:

[0047] Set a second preset time value T4, and continuously record the time taken for the laser ray 21 of laser sensor 2 to hit the opposite edge judgment point C' on two consecutive occasions. calculate and The absolute value of the difference, |△|, if |△| > T4, the alarm device will sound an alarm.

[0048] 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.

[0049] 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.

[0050] 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 the reliability of the miscorrection detection method.

[0051] In one embodiment, k=1, and the preset duration T2 is the pause time required for the cable guide wheel 3 to complete a single-trip path of length N along the axial direction of the I-beam wheel 1 during normal correction. The error correction detection method further includes the following steps:

[0052] Two proximity switches are respectively set at both ends of the cable guide wheel 3. The sensing length of the proximity switches is set. When the distance between the cable guide wheel 3 and the first inner edge 11 or the second inner edge 12 of the I-beam is equal to the sensing length of the proximity switch, the cable guide wheel 3 can move in the opposite direction. When the distance between the cable guide wheel 3 and the first inner edge 11 or the second inner edge 12 of the I-beam is equal to the sensing length of the proximity switch, the timing starts and the time t taken for the cable guide wheel 3 to move from one end of the I-beam 1 to the other end is recorded, T = t.

[0053] Since the cable guide wheel 3 can move in the opposite direction when the distance between it and the first inner edge 11 or the second inner edge 12 of the I-beam is equal to the sensing length of the proximity switch, and since timing starts when the distance between the cable guide wheel 3 and the first inner edge 11 or the second inner edge 12 of the I-beam is equal to the sensing length of the proximity switch, the proximity switch can cooperate with the first inner edge 11 or the second inner edge 12 of the I-beam to perform the positioning and identification function, which is convenient for recording the time t taken for the cable guide wheel 3 to move from one end of the I-beam 1 to the other end, and also enables the cable guide wheel 3 to reciprocate along the axial direction of the I-beam 1.

[0054] In this way, every time the wire guide wheel 3 completes a cycle path of length N 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.

[0055] Furthermore, in one embodiment, the error correction detection method further includes the following steps:

[0056] Set a third preset time value T5, and continuously record the time t1, t2, t3...t taken for the cable guide wheel 3 to move from one end of the I-beam wheel 1 to the other end. n-1 tn Calculate t n With t n-1 The absolute value of the difference, |△|, if |△| > T5, the alarm device will sound an alarm.

[0057] Under normal operating conditions of the tension sensor, the time t taken for the cable guide wheel 3 to move from one end of the I-beam wheel 1 to the other end has a normal time range. Therefore, the time t1, t2, t3...t taken for the cable guide wheel 3 to move from one end of the I-beam wheel 1 to the other end is continuously recorded. n-1 t n , then t n With t n-1 The absolute value of the difference, Δ, should also have a normal range. By setting a third preset time value T5, if Δ is greater than T5, it indicates that a miscorrection has occurred.

[0058] Thus, in addition to detecting whether miscorrection occurs within each loop path of length N, an extra detection step is added, which helps to improve the reliability of the miscorrection detection method.

[0059] In one embodiment, the error correction detection method is performed by a cable laying device, which includes a cable laying guide wheel 3, a controller, a timer assembly, a drive assembly, and a counter-side assembly. The cable laying 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 cable laying 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 a specific position on the I-beam wheel.

[0060] The opposite edge component can be a laser sensor 2. In this case, the preset signal refers to the signal sent by the laser sensor 2 to the controller when the distance between the surface of the I-beam 1 and the laser emission point is equal to the preset distance value. The specific position here refers to the opposite edge judgment point C' that is used in conjunction with the laser sensor 2 for positioning and identification. The opposite edge component can also be a proximity switch. In this case, the preset signal refers to the signal sent by the proximity switch to the controller when the distance between the cable guide wheel 3 and the first inner edge 11 or the second inner edge 12 of the I-beam is equal to the sensing length of the proximity switch. The specific position here refers to the first inner edge 11 or the second inner edge 12 of the I-beam.

[0061] In one embodiment, if the action time T is greater than the alarm time T3, the controller controls the drive component to stop operating and controls the I-beam 1 to stop winding and unwinding.

[0062] This makes it easier to shut down the equipment in a timely manner to troubleshoot the wire cutting machine malfunction.

[0063] In one embodiment, the driving component is a servo motor, and the controller records the action time T through the servo motor.

[0064] However, this is not the only one; in other embodiments, the drive component may also be a cylinder or an electric cylinder, etc.

[0065] The specific process of the cable laying device laying the cable on the I-beam 1 includes the following steps:

[0066] like Figures 1-3 As shown, a certain position on the I-beam 1 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 3 is defined to be located at a preset position 5. With the preset position 5 as the origin, a linear coordinate system is established for the cable guide wheel 3 to move along the axial direction of the I-beam 1, 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 1. 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'. 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 3 moves to coordinates A or B, the cable guide wheel 3 can continue to move in the opposite direction.

[0067] 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 corresponding to 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 corresponding to the second line endpoint B' in the linear coordinate system is calculated.

[0068] 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.

[0069] 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.

[0070] 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 process also includes the following steps:

[0071] 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'.

[0072] 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'.

[0073] 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.

[0074] 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'.

[0075] 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.

[0076] 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'.

[0077] 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.

[0078] 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.

[0079] like Figure 2 As 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.

[0080] In one embodiment, such as Figure 1 and Figure 3As 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.

[0081] 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.

[0082] 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.

[0083] Furthermore, in one embodiment, s1 < l1.

[0084] 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.

[0085] In one embodiment, l1 = 0.

[0086] 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.

[0087] This simplifies the calculation of coordinates A and B.

[0088] However, this is not the only possibility; in other embodiments, l1 ≠ 0.

[0089] In one embodiment, s2 = L - s1.

[0090] 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.

[0091] 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:

[0092] 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.

[0093] 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.

[0094] 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.

[0095] 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'.

[0096] 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:

[0097] 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.

[0098] 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'.

[0099] 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.

[0100] 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.
