[0001] The present invention relates to the field of wire twisting, and in particular to a tubular twisting method, system and intelligent terminal. Background Art

[0002] Tubular stranding refers to passing multiple single wires (usually metal conductors) through a tubular stranding die, and under the action of rotating force, the single wires are spirally stranded around a central axis.

[0003] In the prior art, the wires need to be taken out before twisting them. After the wires are taken out, the staff will usually conduct a rough inspection of the surface of the wires on site. After the inspection and confirmation of no abnormalities, the wires are placed in a twisting device and then twisted.

[0004] Regarding the above-mentioned related technologies, when checking the wires, manual checking by staff takes a corresponding amount of time, and the staff's inspection may be incomplete, which may lead to failure to find abnormalities on the wires, resulting in reduced production quality, which needs to be improved.

[0015] By adopting the above technical solution, the presence of foreign matter on the outer surface of the wire can be known by understanding the inclusion between the detection image information and the foreign matter characteristics. When there is no foreign matter on the outer surface of the wire, the prestress of the wire is released, and when the prestress cannot be released, the wire is heated by a heating device to complete the release of the prestress of the wire, thereby improving production quality.

Then, by understanding the material parameters, the weight of the anti-shake object is known, and then the anti-shake object corresponding to the weight and number of the anti-shake object is pressed on the wire to reduce the shaking of the wire.

[0053] Optionally, a protection method for the wires when they are twisted is also included, and the protection method includes:

[0083] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0084] The embodiment of the present application discloses a tubular twisting method. When there is no foreign matter on the surface of the wire, the prestress of the wire is first released before twisting. When there is foreign matter on the surface of the wire, the foreign matter is blown away by blowing, and when it cannot be blown away, the wire is rotated. When the wire shakes, the shaking of the wire is reduced by knocking, stretching and clamping. And when the wire is twisted, image recognition is used to ensure that there is no abnormality around, thereby improving production quality.

[0085] Reference Figure 1 , a tubular stranding method, comprising the following steps:

[0086] Step 100: Acquire detection image information of a preset detection area.

[0087] The detection area refers to the area used to detect whether there is foreign matter on the outer surface of the wire. The detection area is set in advance by a person skilled in the art and will not be described in detail here. The detection image information refers to the image of the outer surface of the wire. The detection image information is obtained by taking a picture with a camera.

[0088] Step 101: Determine whether the detected image information contains preset foreign body features.

[0089] Foreign body features refer to features used to assist in determining whether there are foreign bodies on the outer surface of the wire. Foreign body features are set in advance by those skilled in the art and will not be described in detail here. By determining whether the detected image information contains foreign body features, it is possible to determine whether there are foreign bodies on the outer surface of the wire.

[0090] Step 102: If and only if it is not included, release the prestress of the wire according to a preset prestress release method, and after the release, obtain the current prestress of the wire.

[0091] When and only when the detected image information does not contain foreign body features, the prestress of the wire is released by using a prestress release method for subsequent use, and after the release, the current prestress of the wire is obtained. The prestress release method refers to a method for releasing the prestress of the wire itself. The prestress release method is set in advance by those skilled in the art and will not be described here. The current prestress refers to the prestress that still exists in the wire itself after the prestress of the wire is released by the prestress release method. The current prestress is measured and obtained by a preset prestress measurement method. The prestress measurement method refers to measuring the current prestress of the wire using the pre-tensioning method.

[0092] And when the detected image information contains foreign matter features, it is necessary to first use a preset removal method to remove foreign matter on the outer surface of the wire. The removal method is described in detail in subsequent steps 200 to 205 and will not be repeated here.

[0093] Step 103: Determine the completion of prestress release according to the excess relationship between the current prestress and the preset reference prestress, or calculate the difference between the current prestress and the reference prestress as the released prestress.

[0094] The reference prestress refers to the prestress used to assist in determining whether the prestress release of the wire has been completed. By determining the excess relationship between the current prestress and the reference prestress, it is possible to determine whether the prestress release of the wire has been completed.

[0095] If the current prestress does not exceed the reference prestress, it means that the prestress release of the wire has been completed.

[0096] If the current prestress exceeds the reference prestress, it means that the wire has not completed prestress release and needs to be further released. Released prestress refers to the value that requires further prestress release of the wire. The released prestress can be obtained by calculating the difference between the current prestress and the reference prestress.

[0097] Step 104: Matching a heating temperature value from a preset heating database according to the released prestress.

[0098] The heating temperature value refers to the temperature used to heat the wire to further release the prestress of the wire. The heating temperature value corresponding to the release of prestress can be matched through the heating database. The heating database contains the corresponding relationship between the release of prestress and the heating temperature value. The heating database is a manually set database and will not be described here.

[0099] The heating temperature value can be obtained by the algorithm formula ,in, is the heating temperature value, To release the prestress, is the cross-sectional area of ​​the wire, is the elastic modulus of the wire, is the linear expansion coefficient of the wire. , as well as It is obtained in advance by those skilled in the art and will not be described in detail here.

[0102] The heating device refers to a hot air gun used to heat the wire. The heating device is controlled to heat the wire at a heating temperature value, thereby completing the prestress release of the wire.

[0103] Step 106: After the prestress is released, a preset twisting device is controlled to twist the wires.

[0104] The twisting device refers to a tubular twisting machine used to twist the wires. When the prestress of the wires is released, the twisting device is controlled to twist the wires.

[0105] Reference Figure 2 , the removal method comprises the following steps:

[0106] Step 200: Identify and mark the location of the foreign object based on the detected image information and the foreign object features.

[0107] The foreign body position refers to the position of the foreign body on the outer surface of the wire. By detecting the image information, the foreign body features can be identified, and then the foreign body features can be marked to obtain the foreign body position.

[0108] Step 201: Determine the blowing angle according to the position of the foreign matter.

[0109] The blowing angle refers to the angle at which the foreign object is blown to remove the foreign object. The blowing angle corresponding to the foreign object position can be matched through a preset blowing database, which includes the correspondence between the foreign object position and the blowing angle. The blowing database is a manually set database and will not be described in detail here.

[0110] Step 202: Control a preset blowing device to blow air at the foreign object position with a preset blowing force according to the blowing angle, and update the detection image information after blowing.

[0111] The blowing device refers to a blower used to blow away foreign matter. The blowing force refers to the force of the blowing device when blowing. The blowing force is set in advance by a person skilled in the art and will not be described in detail here.

[0112] The blowing device is controlled to blow air to the position of the foreign matter at a blowing force and blowing angle, and the detection image information is updated after blowing for subsequent steps.

[0113] Step 203: If and only if the updated detection image information still contains foreign body features, the position of the foreign body after twisting is matched from a preset twisting database according to the position of the foreign body and the preset twisting angle.

[0114] The twisting angle refers to the angle at which the wires are twisted. The twisting angle is set in advance by a person skilled in the art and will not be described in detail here. The position of the foreign matter after twisting refers to the position of the foreign matter after the wires are twisted. If and only if the updated detection image information still contains foreign matter features, the position of the foreign matter and the position of the foreign matter after twisting corresponding to the preset twisting angle need to be matched through the twisting database so that the foreign matter can appear on the outer surface of the twisted wire.

[0115] And when the updated detection image information does not contain the foreign body feature, the twisting device can be directly controlled to twist the wires.

[0116] Step 204: Control the twisting device to twist the wires according to the consistency between the foreign object position after twisting and the preset foreign object reference position after twisting, or match the rotation angle from a preset rotation database according to the foreign object position after twisting and the foreign object reference position after twisting.

[0117] The reference position of foreign matter after twisting refers to the position where the foreign matter should be located on the outer surface of the wire after the wire is twisted. The reference position of foreign matter after twisting is set in advance by a person skilled in the art and will not be described in detail here. The rotation angle refers to the angle at which the wire is rotated.

[0118] By judging the consistency between the position of the foreign matter after twisting and the reference position of the foreign matter after twisting, it is known whether the wire needs to be rotated.

[0119] If the position of the foreign matter after twisting is consistent with the reference position of the foreign matter after twisting, there is no need to rotate the wires, and the twisting device can be directly controlled to twist the wires.

[0120] If the position of the foreign body after twisting is inconsistent with the reference position of the foreign body after twisting, the wire needs to be rotated. The rotation angle corresponding to the position of the foreign body after twisting and the reference position of the foreign body after twisting can be matched through the rotation database, which includes the corresponding relationship between the position of the foreign body after twisting, the reference position of the foreign body after twisting and the rotation angle. The rotation database is a manually set database and will not be described here.

[0121] Step 205: Control a preset rotating device to rotate the wire according to the rotation angle, and control a twisting device to twist the wire after the rotation.

[0122] The rotating device refers to a mechanical arm that clamps the wire and rotates the wire. The rotating device is controlled to rotate the wire at a rotation angle, and after the rotation, the twisting device is controlled to twist the wire.

[0123] Reference Figure 3 , the repair method includes the following steps:

[0124] Step 300: Determine whether the detected image information contains a preset bending feature.

[0125] The bending feature refers to the feature when the wire is bent. The bending feature is set in advance by a person skilled in the art and will not be described in detail here. By judging whether the detection image information contains the bending feature, it is known whether the wire is bent.

[0126] Step 301: If and only if included, control a preset clamping device to place the wire into a preset conveying device, and obtain material parameters of the wire.

[0127] If and only if the detected image information contains bending features, it means that the wire is bent and needs to be straightened. Control the clamping device to clamp the wire into the conveying device and obtain the material parameters of the wire. The clamping device refers to a mechanical arm used to clamp the wire into the conveying device. The conveying device refers to a conveyor belt used to convey the wire to the straightening device. The material parameters refer to the material and strength of the wire. The material parameters are obtained by scanning the QR code on the wire with a preset scanner. The content obtained after scanning the QR code corresponds to the material parameters.

[0128] Step 302: Match the straightening conveying speed from a preset straightening database according to the material parameters.

[0129] The straightening conveying speed refers to the speed at which the conveying device conveys the wire into the straightening device when the wire is being straightened. The straightening conveying speed corresponding to the material parameters is matched in the straightening database, which includes the correspondence between the material parameters and the straightening conveying speed. The straightening database is a manually set database and will not be described in detail here.

[0130] Step 303: Control the conveying device to convey the wire into a preset straightening device at a preset initial conveying speed, and obtain the sensing pressure value of the straightening device.

[0131] The initial conveying speed refers to the conveying speed of the wire before it is conveyed into the straightening device. The initial conveying speed is set in advance by a person skilled in the art and will not be described in detail here. The straightening device refers to a pressure straightening machine used to straighten the wire. The induced pressure value refers to the pressure value borne by the straightening device. The induced pressure value is obtained by a pressure sensor provided on the straightening device. The conveying device is controlled to convey the wire into the straightening device at the initial conveying speed, and the induced pressure value of the straightening device is obtained. In this way, it is known whether the wire has entered the straightening device.

[0132] Step 304: When and only when the sensed pressure value exceeds the preset reference pressure value, control the conveying device to convey the wire at a straightening conveying speed until the sensed pressure value is zero.

[0133] The reference pressure value refers to the pressure value used to assist in determining whether the wire has entered the straightening device. The reference pressure value is set in advance by a person skilled in the art and will not be described in detail here. By determining whether the sensed pressure value exceeds the reference pressure value, it is determined whether the wire has entered the straightening device.

[0134] When the induced pressure value does not exceed the reference pressure value, it means that the wire has not entered the straightening device, and the induced pressure value can be continued to be obtained.

[0135] When the induced pressure value exceeds the reference pressure value, it means that the wire has entered the straightening device. The conveying device needs to be controlled to convey the wire at the straightening conveying speed until the induced pressure value is zero, which means that the straightening of the wire is completed.

[0136] Step 305: After the sensed pressure value is zero, control a preset knocking device to knock the wire with a preset knocking force, and obtain knocking sound information.

[0137] When the induced pressure value is zero, it means that the straightening of the wire is completed. It is necessary to control the tapping device to tap the wire with a tapping force and obtain the tapping sound information. For subsequent steps. The tapping device refers to a tapping hammer used to tap the straightened wire. The tapping force refers to the force with which the tapping device taps the wire. The tapping force is set in advance by a technician in this field and will not be described here. The tapping sound information refers to the sound made when the wire is tapped. The tapping sound information is obtained through a sound sensor set on the tapping device.

[0138] Step 306: According to the consistency between the knocking sound information and the preset reference sound information, the clamping device is controlled to clamp the wire back to the detection area or output a wire abnormality signal to a preset signal transceiver terminal.

[0139] The reference sound information refers to the sound emitted when the wire is not damaged. The reference sound information is set in advance by a person skilled in the art and will not be described in detail here. By judging the consistency between the knocking sound information and the reference sound information, it is known whether the wire is damaged.

[0140] If the knocking sound information is consistent with the reference sound information, it means that there is no damage inside the wire. The clamping device is controlled to clamp the wire back to the detection area for subsequent steps.

[0141] If the knocking sound information is inconsistent with the reference sound information, it means that the wire is damaged inside, and the abnormal wire signal needs to be output to the signal transceiver terminal to prompt the staff. The signal transceiver terminal refers to a terminal for receiving and transmitting various signals. The signal transceiver terminal is set up in advance by a technician in this field and will not be described in detail here.

[0142] Reference Figure 4 , the detection method comprises the following steps:

[0143] Step 400: When twisting the wires using a twisting device, obtain a shaking amplitude value of the wires.

[0144] When the twisting device twists the wires, the shaking amplitude value of the wires is obtained for subsequent steps. The shaking amplitude value refers to the shaking amplitude of the wires when the wires are twisted by the twisting device. The shaking amplitude value is obtained by a displacement sensor.

[0145] Step 401: Match the shake type from a preset shake database according to the shake amplitude value, where the shake type includes shaking and trembling.

[0146] The shaking type refers to the type of shaking of the wire, including shaking and jittering. The shaking type corresponding to the shaking amplitude value can be matched through the shaking database, which includes the corresponding relationship between the shaking amplitude value and the shaking type, where the shaking amplitude value of shaking is greater than the shaking amplitude value of jittering. The shaking database is a manually set database and will not be described in detail here.

[0147] Step 402: When the shaking type is shaking, the stretching force is matched from a preset stretching database according to the material parameters, and the stretching force is output to a preset stretching device to stretch the wire, and the post-stretching shaking value is obtained after stretching.

[0148] The stretching force refers to the force used to straighten the wire to reduce the shaking of the wire. The stretching device refers to the device used to stretch the wire. When the shaking type is shaking, the stretching force corresponding to the material parameters is matched through the stretching database, and the stretching force is output to the stretching device to stretch the wire, so as to reduce the amplitude of the wire shaking. And obtain the post-stretching shaking value after stretching for subsequent steps. The stretching database contains the correspondence between material parameters and stretching force. The stretching database is a manually set database and will not be described here. The post-stretching shaking value is obtained through a displacement sensor.

[0149] Step 403: Update the shake type from the shake database according to the post-pull shake value.

[0150] The post-pull sway value is input into the sway database to update the sway type for subsequent steps. The sway database contains the corresponding relationship between the post-pull sway value and the sway type.

[0151] Step 404: When the updated shaking type is still shaking, the impact force and impact position are matched from the shaking database according to the post-pulling shaking value and the preset wire size information, and the impact force and impact position are output to the preset impact device to control the impact device to impact the wire to reduce the shaking amplitude of the wire.

[0152] When the updated shaking type is still shaking, the shaking database is used to match the impact force and impact position corresponding to the shaking value after pulling and the wire size information for subsequent steps. The shaking database contains the correspondence between the shaking value after pulling, the wire size information, the impact force and the impact position. The wire size information refers to the length and diameter of the wire. The wire size information is set in advance by a technician in this field and will not be repeated here. The impact force refers to the force with which the impact device hits the wire. The impact position refers to the position where the impact device hits the wire. The impact device refers to a drop hammer used to hit the wire. The matched impact force and impact position are output to the impact device to control the impact device to hit the wire to reduce the shaking amplitude of the wire.

[0153] Reference Figure 5 , the treatment method to reduce shaking includes the following steps:

[0154] Step 500: Match the shaking intensity from a preset shaking database according to the material parameters and the shaking amplitude value.

[0155] The shaking intensity refers to the strength of the wire when it is shaken. The shaking intensity corresponding to the material parameters and the shaking amplitude value can be matched through the shaking database, which contains the corresponding relationship between the material parameters, the shaking amplitude value and the shaking intensity. The shaking database is a manually set database and will not be described here.

[0156] Step 501: Match the clamping force from a preset clamping database according to material parameters.

[0157] The clamping force refers to the force of the clamping device when clamping the wire. The clamping force corresponding to the material parameters can be matched through the clamping database, which contains the corresponding relationship between the material parameters and the clamping force. The clamping database is a manually set database and will not be described here.

[0158] Step 502: Calculate the number of clamping devices according to the clamping force and a preset reference clamping force.

[0159] The reference clamping force refers to the force that the wire can withstand from a single clamping device. The number of clamping devices refers to the number of clamping devices used to ensure that the wire can be clamped with the clamping force. The number of clamping devices is obtained by calculating the quotient of the clamping force divided by the reference clamping force. If the quotient is a decimal, the decimal part is removed and the integer part is added by one to obtain the number of clamping devices.

[0160] Step 503: Perform matching analysis from the clamping database according to the number of clamping devices, wire size information and shaking amplitude value to obtain the clamping position.

[0161] The clamping position refers to the position of the clamping device when clamping the wire. The clamping database can match the number of clamping devices, wire size information, and the clamping position corresponding to the swing amplitude value, which contains the corresponding relationship between the number of clamping devices, wire size information, swing amplitude value, and clamping position.

[0162] Step 504: Control the preset clamping device to clamp the clamping position with a clamping force to reduce the shaking of the wire.

[0163] The clamping device refers to a mechanical arm used to clamp the wire to reduce the shaking of the wire. The clamping device is controlled to clamp the clamping position with a clamping force to reduce the shaking of the wire.

[0164] Reference Figure 6 The processing method for the jitter type is jitter, including the following steps:

[0165] Step 600: When the shaking type is jitter, the number of anti-shake objects is matched from a preset jitter database according to the shaking amplitude value and the wire size information.

[0166] The anti-shake object refers to the anti-shake block used to reduce the jitter of the wire. The number of anti-shake objects refers to the number of objects used to reduce the jitter of the wire. When the shaking type is shaking, the shaking amplitude value and the number of anti-shake objects corresponding to the wire size information are matched through the shaking database, which contains the corresponding relationship between the shaking amplitude value, the wire size information and the number of anti-shake objects. The shaking database is a manually set database and will not be described here.

[0167] Step 601: Determine the position of the anti-shake object according to the number of anti-shake objects and the wire size information.

[0168] The position of the anti-shake object refers to the position where the anti-shake object is placed on the cable. Since the anti-shake objects need to be evenly placed on the cable to reduce the shaking of the cable, the distance between the two anti-shake objects can be known by calculating the quotient of the cable size information divided by the number of anti-shake objects, and then the anti-shake object position can be obtained.

[0169] Step 602: Match the anti-shake object weight from a preset shake database according to the material parameters.

[0170] The weight of the anti-shake object refers to the weight of the anti-shake object. The anti-shake object weight corresponding to the material parameters can be matched through the jitter database, which contains the corresponding relationship between the material parameters and the anti-shake object weight. The jitter database is a manually set database and will not be described here.

[0171] Step 603: Match the corresponding anti-shake object from the anti-shake database according to the weight of the anti-shake object, and control the anti-shake objects of corresponding weight and quantity to move to the anti-shake object position to reduce the wire shaking.

[0172] The anti-shake database is used to match the anti-shake object with the weight of the anti-shake object, and the anti-shake objects with the corresponding weight and quantity are controlled to move to the anti-shake object position to reduce the wire shaking. The anti-shake database contains the corresponding relationship between the weight of the anti-shake object and the anti-shake object.

[0173] Reference Figure 7 , the protection method includes the following steps:

[0174] Step 700: Obtain the output signal of the twisting device.

[0175] The output signal refers to the signal of the twisting device when it is working or on standby. The signal is output to the signal transceiver terminal through the signal transceiver set in the twisting device, and then the output signal is obtained by calling from the signal transceiver terminal.

[0176] Step 701: When the output signal is consistent with the preset working signal, the twisting image information is obtained.

[0177] The working signal refers to the signal sent by the twisting device when it is twisting. The working signal is set in advance by a person skilled in the art and will not be described in detail here. When the output signal is consistent with the working signal, it means that the twisting device is twisting and twisting image information needs to be obtained for subsequent steps. The twisting image information refers to the image of the twisting device when it is twisting. The twisting image information is obtained by taking a picture with a camera.

[0178] Step 702: Determine whether the twisted image information contains a preset abnormal feature.

[0179] The abnormal feature refers to the feature around the twisting device other than the twisting device, wire and ground. The abnormal feature is set in advance by a person skilled in the art and will not be described in detail here. By determining whether the twisting image information contains the abnormal feature, it is known whether there is an abnormality around the twisting device.

[0180] Step 7021: If included, the abnormality type is identified from a preset abnormality database based on the twisted image information and abnormality features, and the abnormality type includes biological abnormality and object abnormality.

[0181] If the twisting image information contains abnormal features, it means that there are abnormalities around the twisting device. It is necessary to match the abnormal type corresponding to the abnormal features in the twisting image information through the abnormal database, which contains the correspondence between abnormal features and abnormal types. The abnormal database is a manually set database and will not be described here. The abnormal type refers to the type of abnormal feature, and the abnormal type includes biological abnormalities and object abnormalities. Biological abnormality refers to the abnormality of the presence of staff around the twisting device. Object abnormality refers to the abnormality of the presence of paper and other garbage around the twisting device.

[0182] Step 70211: Based on the biological anomaly, control the preset alarm device to sound an alarm and stop the operation of the twisting device until the biological anomaly exits the preset alarm area.

[0183] When the abnormality type is a biological abnormality, the alarm device is controlled to give an alarm prompt and stop the twisting device until the biological abnormality exits the alarm area, and then the twisting device is restarted. The alarm device refers to an alarm used to give an alarm prompt to the staff. The alarm area refers to an area used to separate the staff from the twisting device to ensure work safety. The alarm area is set in advance by those skilled in the art and will not be described in detail here.

[0184] Step 70212: Based on the object abnormality, the abnormal area is framed and marked according to the twisted image information and abnormal features, and the preset suction device is controlled to absorb the abnormal features in the abnormal area with a preset suction force.

[0185] The abnormal area refers to the specific area around the twisting device where the abnormal object is located when the abnormal type is an abnormal object. The suction device refers to a suction fan used to absorb the abnormal object. The suction force refers to the suction force of the suction device when absorbing the abnormal object.

[0186] The abnormal features can be framed by the twisted image information, and then the framed area can be marked to obtain the abnormal area. Then the suction device is controlled to absorb the abnormal features in the abnormal area with the suction force to prevent the abnormal features from entering the twisting device and interfering with the twisting device and the wire.

[0187] Step 7022: If not included, control the preset blowing devices on both sides of the twisting device to blow air at a preset blowing intensity to form a protective wind curtain.

[0188] The blowing device refers to a blower used to blow air to both sides of the twisting device to form a protective wind curtain on both sides. The blowing intensity refers to the strength of the blowing device to form the protective wind curtain. The blowing intensity is set in advance by a person skilled in the art and will not be described in detail here. The protective wind curtain refers to a wind curtain used to prevent abnormal features from entering the twisting device.

[0189] If the twisting image information does not contain abnormal features, it means that there is no abnormality around the twisting device. The blowing devices on both sides of the twisting device are controlled to blow air at a blowing intensity to form a protective air curtain.
