However, this manual method is susceptible to human error, lacks precision in parameter control, and has a slow response time. Particularly during the insulation material melting and insulation layer extrusion stages, even minor temperature fluctuations can lead to uneven insulation thickness and reduced voltage withstand capability.

[0022] Reference Figure 1 The diagram shown is a flowchart illustrating a cable production quality monitoring method based on real-time data according to an embodiment of the present invention. In this embodiment, the cable production quality monitoring method based on real-time data includes: S1. Receive cable production quality monitoring instructions, and confirm the cable production environment based on the cable production quality monitoring instructions. The cable production environment includes: n initial cables, extruder, cooling device, infrared thermometer, laser diameter gauge, temperature sensor and thermocouple. The extruder includes a first transmission screw, a second transmission screw, a feeding zone, a heating zone and an extrusion zone. The thermocouple includes a hot end and a cold end. The feeding zone and the heating zone are connected by the first transmission screw, and the heating zone and the extrusion zone are connected by the second transmission screw.
[0023] It should be explained that the initial cable is obtained by twisting together multiple mutually insulated wires, and this initial cable is pre-produced in a factory. The cable is the initial cable with an insulation layer. Cable production quality control instructions are generally initiated by the technician responsible for cable production in the factory.
[0024] Furthermore, the insulation layer plays a role in electrical isolation, preventing current leakage and short circuits in cables, and is crucial for the safe and normal use of cables. Therefore, the main focus of this invention is to achieve quality monitoring of the cable insulation layer during production.
[0025] For example, Zhang is a technician in a factory responsible for producing cables. Now Zhang needs to produce cables in the factory, so Zhang initiates the cable production quality monitoring instruction.
[0026] In this embodiment of the invention, the environment used for producing cables is a cable production environment, which includes: n initial cables, an extruder, a cooling device, an infrared thermometer, a laser diameter gauge, a temperature sensor, and a thermocouple. The extruder includes a first transmission screw, a second transmission screw, a feeding zone, a heating zone, and an extrusion zone. The thermocouple includes a hot end and a cold end. The feeding zone and the heating zone are connected by the first transmission screw, and the heating zone and the extrusion zone are connected by the second transmission screw.
[0027] It should be explained that an extruder is a device used to produce cables. Its heating zone heats the plastic to a molten state, and the molten plastic is then extruded into the initial cable through the extrusion zone to form a continuous and dense insulation layer, thereby manufacturing the cable. Both the first and second transfer screws are located within the extruder. The main function of the first transfer screw is to transport the initial material from the feeding zone to the heating zone, while the main function of the second transfer screw is to transport the target material from the heating zone to the extrusion zone.
[0028] It should be understood that the feeding zone is an area within the extruder responsible for the initial processing of raw materials. The feeding zone includes a pressure sensor, a material magazine, and a mixing chamber. The material magazine contains the raw materials and the feed inlet, while the mixing chamber contains an agitator. The pressure sensor is a pressure sensor that converts the measured pressure value into an electrical signal and outputs it externally. It is located at the bottom center of the outside of the mixing chamber. Optionally, an LC103B-200 stainless steel S-type load cell is used as the pressure sensor. The material magazine is a funnel-shaped container made of stainless steel or aluminum used to store the raw materials. The feed inlet is an outlet at the bottom of the material magazine funnel. Generally, opening or closing the feed inlet controls the feeding or stopping of raw materials into the mixing chamber. The mixing chamber is a horizontal cylindrical container made of stainless steel or aluminum. An internal agitator shears and mixes the raw materials. The agitator is a stainless steel spiral blade placed in the mixing chamber. It shears and mixes the raw materials, expelling internal air and making the material denser for subsequent processing. Raw materials refer to plastic granules free of impurities. For example, PVC plastic pellets.
[0029] Understandably, raw materials are replenished to the material warehouse periodically by the factory's technicians.
[0030] It should be explained that the heating zone is an area within the extruder where the initial material is heated and melted via an internal resistance heating coil. The initial material refers to the raw material that has undergone preliminary processing in the feeding zone. The resistance heating coil is a type of heating coil that uses an electrothermal alloy wire as the heating element, converting electrical energy into heat energy through the Joule effect of electric current to heat the initial material.
[0031] Importantly, the extrusion zone is an area within the extruder responsible for extruded and wrapped the target material onto the initial cable. The extrusion zone includes the extrusion die, traction device, and third transfer screw. The target material refers to the initial material after being heated and melted in the heating zone. The traction device is used to pull the initial cable; optionally, a winch from the Mailefer-PullingCapstan Series is used as the traction device. The third transfer screw, located in the extrusion zone, primarily transports the target material at a certain speed to the die sleeve of the extrusion die. The extrusion die is a stainless steel mold with a specific shape, including a die core and a die sleeve. The initial cable is extruded through the die core, and the target material is extruded through the die sleeve. When the initial cable and target material are extruded simultaneously through the die core and die sleeve, the target material wraps around the initial cable.
[0032] It should be explained that the cooling device consists of multiple cooling water tanks containing water at different temperatures. The purpose of the cooling device is to gradually cool and shape the target cable. For specific applications of the target cable, please refer to subsequent embodiments. The infrared thermometer is an instrument that measures temperature using infrared thermal imaging technology; optionally, an infrared imager from the HIKMICRO M Series can be used as the infrared thermometer. The laser diameter gauge's main function is to measure the cable's diameter; optionally, a TAKANO LY-3503D can be used as the laser diameter gauge. The temperature sensor is an electronic instrument with a built-in thermistor and resistance meter; optionally, a B3950 thermistor can be used.
[0033] It should be understood that a thermocouple is a temperature-sensing element, consisting of a hot junction and a cold junction. Optionally, a thermocouple with a K-type calibration is used. The hot junction is the end of the thermocouple where the higher temperature region is located. The cold junction is the end of the thermocouple where the lower temperature region is located. Temperature is measured by the temperature gradient between the hot and cold junctions. The specific temperature measurement principle is existing technology and will not be elaborated here.
[0034] Specifically, receiving cable production quality monitoring instructions and confirming the cable production environment based on these instructions includes: After receiving the cable production instruction, start the extruder; After startup, acquire n initial cables and perform self-tests on the temperature sensor, cooling device, and thermocouple. After the self-test passes, the parameters of the infrared thermometer and laser diameter gauge are set respectively until the parameters are successfully set, thus obtaining a cable production environment including n initial cables, an extruder, a cooling device, an infrared thermometer, a laser diameter gauge, a temperature sensor, and a thermocouple.
[0035] It should be explained that the n initial cables are pre-produced by the factory and obtained by the technician, who then places them in designated positions on the extruder. The parameters for the infrared thermometer and laser diameter gauge are set, including measurement frequency and operating time.
[0036] S2. The initial material and its density are obtained by using the feeding area, and the initial material is transported to the heating area by the first transfer screw to obtain the working heating area.
[0037] It should be explained that the working heating zone is the heating zone that receives the initial material.
[0038] Specifically, the method of obtaining the initial material and material density using the feeding area includes: The feeding area includes a pressure sensor, a material storage chamber, and a mixing chamber. The material storage chamber includes raw materials and a feed inlet. The mixing chamber contains an agitator, and the pressure sensor is located at the bottom center of the outside of the mixing chamber. The initial pressure is obtained by measuring the mixing chamber using a pressure sensor, and the material feed port of the material storage is opened. The raw material is then fed into the mixing chamber through the material storage after the feed port is opened. The time when the feed inlet is opened is taken as the first initial time. The time is recorded in real time from the first initial time to obtain the feed time. When the feed time reaches the preset feed time threshold, the feed inlet is closed to obtain the target mixing chamber. The target mixing chamber is measured using a pressure sensor to obtain the update pressure. The material density is obtained using the material feeding time threshold, the initial pressure, and the update pressure. The initial material is obtained using the agitator and the original material in the target mixing chamber.
[0039] It should be explained that the initial pressure refers to the pressure exerted by the mixing chamber on the pressure sensor. The target mixing chamber refers to the mixing chamber after receiving material from the material storage tank. The update pressure refers to the pressure exerted by the target mixing chamber on the pressure sensor. The first initial time refers to the time it takes to open the feed inlet. The preset feed time threshold is set by the technician. Material density reflects the initial density of the material; the higher the material density, the higher the initial density of the material.
[0040] For example, the computer reads the pressure sensor reading and uses this reading as the initial pressure. At 10:00, the feed port is opened, and the material library feeds the raw material into the mixing chamber through the feed port. Taking 10:00 as the first initial time, and Xiao Zhang sets the feed time threshold to 5 minutes, the feed port is closed at 10:05. At this time, the mixing chamber after the feed is the target mixing chamber. The pressure sensor reading at this time is read and used as the update pressure. Then, the agitator in the mixing chamber is started to shear and mix the raw material, remove the air, and make the raw material more compact, thereby obtaining the initial material.
[0041] Furthermore, the method of obtaining material density using the feeding time threshold, initial pressure, and renewal pressure includes: The density of the material is calculated using the following formula: in, For material density, As the initial pressure, To update the pressure, The area of the preset feed inlet. It is the acceleration due to gravity. This is the material feeding time threshold.
[0042] It should be explained that the preset feed port area is determined by the parameters of the material library corresponding to the feed port. The gravitational acceleration is taken as 9.8 m / s².
[0043] For example, if the initial pressure is 500 N, the refresh pressure is 800 N, the area of the feed inlet is 0.2 square meters, and the feed time threshold is 150 seconds, then the material density is 1. .
[0044] S3. Fix the cold end of the thermocouple onto the extruder to obtain the temperature measuring cold end. Place the hot end of the thermocouple into the working heating zone to obtain the temperature measuring hot end. Use the temperature measuring cold end, temperature measuring hot end, working heating zone and temperature sensor to obtain the target melting temperature and target material.
[0045] It should be explained that the cold end for temperature measurement refers to the cold end fixed on the extruder, while the hot end for temperature measurement refers to the hot end placed in the working heating zone.
[0046] Specifically, the method of obtaining the target melting temperature and target material using a temperature sensing cold end, a temperature sensing hot end, a working heating zone, and a temperature sensor includes: The working heating zone includes the initial material and the resistance heating coil; The resistance heating coil is activated, wherein the heating power of the resistance heating coil is preset as the initial heating power, the time of activation of the resistance heating coil is set as the second initial time, and the time is recorded in real time from the second initial time to obtain the heating time. The initial material is heated by the activated resistance heating coil to obtain molten material. When the heating time reaches the preset heating time threshold, the resistance heating coil is turned off. The test electromotive force is obtained using the hot junction and the molten material, and the reference room temperature is obtained using a temperature sensor. Based on the reference room temperature and the cold junction, the compensation electromotive force is determined. The actual electromotive force is calculated using the test electromotive force and the compensation electromotive force. The calculation formula is as follows: in, This is the actual electromotive force. To test the electromotive force, To compensate for the electromotive force; Confirming the first using actual electromotive force A melting temperature, wherein... ≥2; The first of the pre-constructed melting temperature series Replace item with the first A melting temperature is calculated, resulting in an updated temperature sequence. The first item in this sequence is pre-defined as the first melting temperature. The melting temperature sequence is shown below: in, It is the first term in the melting temperature series. It is the second term in the melting temperature series. The first of the melting temperature series item; Using the first The melting temperature was confirmed in the updated temperature series. The melting temperature, using the first The melting temperature and the first The melting temperature difference is calculated based on the melting temperature, using the following formula: in, For melting temperature difference, For the first A melting temperature, For the first One melting temperature; Compare the melting temperature difference with the preset temperature difference threshold and compare the first... The melting temperature is the same as the preset material melting point temperature; If the melting temperature difference is greater than the preset temperature difference threshold or the first If the melting temperature is lower than the material's melting point, then the first melting temperature is used. A heating power prediction model is constructed using the melting temperature and update temperature series, and the model is used to... A prediction model for melting temperature and heating power confirmed the target heating power; Obtain the execution count of the starting resistor heating coil, where the execution count is... Next, then As Using the target heating power as the initial heating power, the molten material as the initial material, and the updated temperature series as the melting temperature series, the process returns to the step of starting the resistance heating coil until the melting temperature difference is less than or equal to the temperature difference threshold and the first... The melting temperature is greater than or equal to the material's melting point temperature; If the melting temperature difference is less than or equal to the temperature difference threshold and the first The melting temperature is greater than or equal to the melting point temperature of the material. The target melting temperature is defined as the melting temperature, and the molten material is defined as the target material.
[0047] It should be explained that the initial heating power is the power used by the heating resistance coil, and this initial heating power is set by the technician when the heating coil is first started. The second initial time is the time it takes to start the heating resistance coil. The molten material is the initial material after heating. The heating time threshold is set by the technician. The melting temperature is the temperature of the molten material.
[0048] It should be understood that obtaining the test electromotive force using the temperature measuring hot junction and molten material means that the temperature measuring hot junction of the thermocouple will generate an electromotive force under the action of the temperature of the molten material, and the instrument in the thermocouple can display the specific electromotive force value when the electromotive force is generated, which is the test electromotive force.
[0049] It is understood that the determination of the compensating electromotive force based on the reference room temperature and the cold junction of the thermocouple means that the cold junction of the thermocouple will generate an electromotive force under the influence of the reference room temperature, and the electromotive force value corresponding to the reference room temperature can be found through the K thermocouple calibration number millivolt to temperature conversion table. This electromotive force value is the compensating electromotive force. For specific applications of the reference room temperature, please refer to the following embodiments.
[0050] It should be understood that the thermocouple's hot junction generates an electromotive force under the influence of the temperature of the molten material, and the thermocouple's cold junction generates an electromotive force under the influence of the reference room temperature. This is existing technology and will not be elaborated here.
[0051] Understandably, in the K thermocouple calibration millivolt to temperature conversion table, the relationship between electromotive force and temperature only applies when the temperature of the cold junction is 0. This condition is met at the time, therefore, when the cold junction temperature is not 0. In some cases, the temperature at the hot end of the temperature sensor cannot be directly calculated from the measured electromotive force (EMF). The temperature at the cold end needs to be considered. Therefore, a compensation EMF is obtained using the reference room temperature at the cold end location. This compensation EMF is then added to the measured EMF to obtain the actual EMF, which restores the temperature of the cold end to 0. In this case, the actual electromotive force is then converted into the corresponding temperature in the K thermocouple graduation number millivolt to temperature conversion table. This temperature can represent the temperature of the hot junction, i.e., the melting temperature.
[0052] For example, when the instrument in the thermocouple displays an electromotive force of 10 mV, the reference room temperature measured by the temperature sensor is 25°C. That is, the cold end temperature is approximately 25°C. From the table, the compensated electromotive force is 1mV, and the calculated actual electromotive force is 11mV. Then, by converting the actual electromotive force using the K thermocouple calibration number millivolt to temperature conversion table, the melting temperature is found to be 273°C. .
[0053] It should be understood that the instruments in thermocouples can display the specific electromotive force value when the electromotive force is generated, which is existing technology and will not be elaborated here.
[0054] Importantly, the first The melting temperature refers to the first melting temperature. The melting temperature obtained after the first activation of the starting resistor heating coil, and The initial value is 2. For example, the first activation of the resistance heating coil corresponds to the second melting temperature, the second activation corresponds to the third melting temperature, and so on. The target heating power is the ideal heating power calculated through a heating power prediction model. The target molten material refers to the molten material in the working heating zone that meets the conditions. The target melting temperature refers to the temperature of the target molten material.
[0055] It should be explained that the temperature difference threshold is set by the technician. The material melting point temperature is the temperature at which the original material melts, which is related to the physical properties of the original material and is also set by the technician. In the melting temperature series, the first item is the first melting temperature, which is set in advance by the technician; the rest... Each item is an empty set, and Much larger Updating the temperature series refers to updating the melting temperature series by retrieving the first element from the set of melting temperatures. Replace item with the first A sequence of melting temperatures following a given melting temperature.
[0056] For example, Xiao Zhang starts the resistance heating coil with an initial heating power of 5000 watts. Since this is the first time the resistance heating coil is started, then... If the start time is 15:00, then 15:00 is taken as the second initial time. When the heating time reaches the set heating time threshold of 2 minutes, i.e., at 15:02, the second melting temperature is measured to be 60. The pre-constructed melting temperature series is , the second item Replace with 60 The updated temperature series is obtained as follows The first melting temperature is found in the updated temperature series using the second melting temperature. The calculated melting temperature difference is 35°C. Greater than the temperature difference threshold 2 A heating power prediction model is then constructed, and the target heating power is calculated to be 2000 watts. This 2000 watts is then used as the initial heating power. Since the step of starting the resistance heating coil has already been performed once, then... Change the setting to 3, and restart the resistance heating coil with an initial heating power of 2000 watts. Record the start time as 15:03. Then, at 15:05, the third melting temperature is measured to be 75. At this point, the melting temperature sequence is: The third item Replace with 75 The updated temperature series is obtained as follows The second melting temperature is found in the updated temperature series using the third melting temperature. The calculated melting temperature difference is 15. Greater than the temperature difference threshold 2 Then continue calculating the target heating power, and so on, until the melting temperature difference is 1 after the resistance heating coil has been activated 11 times. Less than the temperature difference threshold 2 And the twelfth melting temperature is 152. Greater than the material's melting point temperature of 150°C Then the twelfth melting temperature is 152. The target melting temperature is used as the target molten material.
[0057] Specifically, the method of obtaining a reference room temperature using a temperature sensor includes: Start the temperature sensor, which includes a thermistor and a resistance meter; The temperature sensor is fixed on the extruder, and the resistance meter reading is obtained by using the fixed temperature sensor. The resistance meter reading is used as the resistance value of the thermistor. The reference room temperature is calculated using the resistance of a thermistor, as shown in the following formula: in, For reference room temperature, The preset reference temperature, The resistance value of the thermistor. The preset reference resistance value, The first material constant is preset. This is a preset second material constant.
[0058] It should be explained that the ohmmeter reading is the actual reading of the ohmmeter. The thermistor's resistance is its actual resistance value. The reference room temperature refers to the temperature at the location of the temperature sensor on the extruder. Since the cold junction of the temperature sensor is also located on the extruder, the reference room temperature represents the temperature of the cold junction.
[0059] For example, after the temperature sensor is fixed to the extruder, the thermistor in the temperature sensor will determine its resistance value according to the temperature of the extruder, and the ohmmeter will also display a reading, which is the ohmmeter reading.
[0060] It should be understood that the resistance of a thermistor is determined by the temperature of the extruder, which is a physical characteristic of the thermistor and will not be elaborated here.
[0061] It should be explained that the first and second material constants are parameters used to describe the temperature characteristics of a negative temperature coefficient thermistor, reflecting the sensitivity of its resistance to temperature changes. The preset reference temperature, reference resistance, and the first and second material constants are determined by the thermistor's model. For example, a thermistor model B3950 has a reference resistance of 10000Ω and a reference temperature of 25℃. The specific values of the first and second material constants can be found in the thermistor's product manual.
[0062] Furthermore, the heating power prediction model is as follows: in, For the target heating power, This represents the maximum power of the resistance heating coil. For the first A melting temperature, To update the temperature series of the first item, The melting point temperature of the material. The preset material safety temperature, and 1≤ ≤ , < , This is the preset temperature weighting coefficient.
[0063] It should be explained that the temperature weighting coefficient is set by the technician. The maximum power of the resistance heating coil is determined by the model of the resistance heating coil. The safe temperature of the material is related to the physical properties of the original material and is set in advance by the technician.
[0064] For example, if the temperature series is updated as The temperature weighting coefficient is 10, the maximum power of the resistance heating coil is 5000 watts, and the material melting point temperature is 150°C. The material's safe temperature is 170°C. Because the fifth melting temperature is Less than 150°C of the material's melting point Construct a heating power prediction model and substitute it into the calculation: The target heating power is approximately 3383 watts.
[0065] It should be understood that, in this embodiment of the invention, the heating power prediction model is represented by a three-part piecewise function, wherein, when the first... When the melting temperature is lower than the melting point temperature of the material, the calculation is performed on the first... The smaller the difference between the melting temperature and the material's melting point, the lower the heating power. Therefore, a lower heating power is used to restart the resistance heating coil, resulting in a smoother heating process and preventing overheating. The summation term in the formula is to prevent the target temperature from being reached when the heat dissipation from the environment equals the heat generated by the resistance heating coil. When the melting temperature is greater than the melting point temperature of the material, by comparing the first... The difference between the initial melting temperature and the material's safe temperature is used to further limit the heating power, ensuring it remains stably above the material's melting point. If the initial heating power is set too high, causing the melting temperature to exceed the safe temperature, the heating power is immediately reduced to zero, thus cooling the material. Ultimately, under the control of the heating power prediction model, the temperature of the molten material is stabilized above its melting point and no longer fluctuates, achieving the desired effect.
[0066] S4. Use the second transfer screw to transport the target material to the extrusion zone to obtain the target extrusion zone. Use the material density, target melting temperature, target extrusion zone, infrared thermometer, cooling device and n initial cables to obtain n cooling cables.
[0067] It should be explained that the target extrusion zone is the extrusion zone that has received the target material.
[0068] In detail, the process of obtaining n cooling cables using material density, target melting temperature, target extrusion zone, infrared thermometer, cooling device, and n initial cables includes: The target extrusion zone includes the target material, the extrusion die, the traction device, and the third transmission screw. The extrusion die includes the die core and the die sleeve. Extract initial cables sequentially from the n initial cables, and perform the following operations on the extracted initial cables: The traction device is started, wherein the traction speed of the traction device is preset as the initial traction speed. The traction device is used to pull the initial cable into the core of the extrusion mold after it is started, so as to obtain the new cable. The target material is transported to the die sleeve of the extrusion mold using the third transfer screw to obtain the new material; The angle difference between the die core and die sleeve in the extrusion mold is obtained, and the discharge speed is calculated using the angle difference and the material density. The calculation formula is shown below: in, For the discharge speed, Due to the angle difference, For the preset target density, The preset rotational speed of the third transmission screw is given, where the unit of rotational speed of the third transmission screw is revolutions per second. The pitch of the third transmission screw to be acquired; The replacement material is wrapped around the replacement cable using an extrusion mold to obtain the target cable; A cooling device is used to cool the target cable to obtain a cooled cable. The cooling cable is tested using an infrared thermometer to obtain the cooling temperature. The target traction speed is obtained using the cooling temperature, discharge speed, and target melting temperature. The target traction speed is used as the initial traction speed, and the process is repeated until n cooling cables are obtained.
[0069] It should be explained that the traction speed refers to the speed at which the traction device pulls the initial cable through the die core. The initial traction speed is set by the technician. The replacement cable is the initial cable that passes through the die core of the extrusion mold. The replacement material is the target material transported to the die sleeve of the extrusion mold. The target cable is the replacement cable wrapped with the replacement material. The cooling cable refers to the target cable after it has been cooled by the cooling device.
[0070] Understandably, the angle difference between the die core and die sleeve in an extrusion die is related to the model of the extrusion die.
[0071] It should be explained that the discharge speed refers to the speed at which the target material is extruded through the extrusion die. The target density and the rotational speed of the third transmission screw are set by the technician. The pitch of the third transmission screw is related to the model of the third transmission screw.
[0072] It should be understood that the cooling operation of the target cable using the cooling device refers to passing the target cable sequentially through multiple water tanks containing water at different temperatures within the cooling device, allowing the target cable to gradually cool and set. The order of passing through the different water tanks is from the highest temperature tank to the lowest temperature tank. The detection operation of the cooled cable using an infrared thermometer refers to using an infrared thermometer to photograph the cooled cable and reading the temperature at the corresponding location on the cooled cable from the infrared thermometer, which is then used as the cooling temperature.
[0073] It should be noted that the cooling temperature refers to the temperature of the cooling cable. The target traction speed is the ideal traction speed.
[0074] Furthermore, the method of obtaining the target traction speed by utilizing the cooling temperature, discharge rate, and target melting temperature includes: The temperature difference is calculated using the target melting temperature and cooling temperature, as shown in the following formula: in, For the temperature difference, The target melting temperature, This refers to the cooling temperature. The target traction speed is calculated using the temperature difference, as shown in the following formula: in, For the target traction speed, The preset temperature threshold, and These are the preset first material viscosity coefficient and the second material viscosity coefficient, respectively.
[0075] It should be explained that the temperature difference is the absolute value of the difference between the target melting temperature and the cooling temperature. The temperature threshold is set by the technician. The viscosity coefficients of the first and second materials are related to the physical properties of the materials and are obtained and set in advance by the technician.
[0076] Generally speaking, temperature affects the viscosity of the replacement material, which in turn affects the thickness and uniformity of the replacement material covering the replacement cable. By detecting the cooling temperature of each cooling cable output, the temperature threshold is calculated, and the traction speed is adjusted in real time according to the degree of temperature change. The traction speed and the discharge speed are balanced, so that when processing the next initial cable, the thickness of the replacement material covering the replacement cable is more uniform.
[0077] S5. Perform the following operation on each of the n cooling cables: use a laser diameter gauge to measure the diameter of the cooling cable, and calculate the diameter difference using the cable diameter and the preset target diameter.
[0078] In detail, the calculation of the diameter difference using the cable diameter and the preset target diameter is shown in the following formula: in, This is the diameter difference. The diameter of the cable. The target diameter.
[0079] It should be explained that the diameter difference is the absolute value of the difference between the cable diameter and the target diameter.
[0080] It should be understood that the measurement operation of the cooling cable using a laser diameter gauge to obtain the cable diameter refers to passing the cooling cable through the laser diameter gauge, measuring the diameter at multiple locations on the cooling cable, and taking the average value to obtain the cable diameter. Measuring the diameter of a cooling cable using a laser diameter gauge is existing technology and will not be elaborated upon here.
[0081] S6. Compare the diameter difference with the preset diameter difference threshold. If the diameter difference is less than or equal to the diameter difference threshold, the cooling cable is considered a qualified cable, thus completing the quality monitoring of cable production.
[0082] It should be explained that the diameter difference threshold is set by the technician. A qualified cable refers to a cooling cable that meets the requirements.
[0083] For example, the computer compares the diameter difference of each of the ten cooling cables with the diameter difference threshold, selects nine cooling cables, and marks them. Technician Xiao Zhang then extracts the nine marked cooling cables as nine qualified cables, thus completing the quality monitoring of cable production.
[0084] To address the problems described in the background art, this invention receives cable production quality monitoring instructions and, based on these instructions, identifies the cable production environment. This environment includes: n initial cables, an extruder, a cooling device, an infrared thermometer, a laser diameter gauge, a temperature sensor, and thermocouples. The extruder comprises a first transmission screw, a second transmission screw, a feeding zone, a heating zone, and an extrusion zone. The thermocouples include a hot end and a cold end. The feeding zone and the heating zone are connected by the first transmission screw, and the heating zone and the extrusion zone are connected by the second transmission screw. Therefore, this invention provides an automated production environment by constructing a complete cable production environment, thereby improving the automation level of cable production and facilitating practical application. This lays the foundation for quality monitoring of the cable. Furthermore, the initial material and its density are obtained using the feeding zone, and the initial material is transported to the heating zone using the first transfer screw, thus obtaining the working heating zone. It is evident that this embodiment of the invention obtains the initial material through the feeding zone and provides it to the heating zone through the first transfer screw, ensuring the continuity of the initial material processing and obtaining the material density in advance, facilitating subsequent control of the cooling material acquisition process based on the material density. The cold end of the thermocouple is fixed to the extruder to obtain the temperature-sensing cold end, and the hot end of the thermocouple is placed in the working heating zone to obtain the temperature-sensing hot end. The target melt is obtained using the temperature-sensing cold end, the temperature-sensing hot end, the working heating zone, and the temperature sensor. Regarding temperature and target material, this embodiment of the invention uses thermocouples and temperature sensors to obtain real-time information about the working heating zone, thereby adjusting the heating power of the working heating zone in real time and improving the automation level of target material acquisition. The target material is transported to the extrusion zone using a second transfer screw, resulting in the target extrusion zone. Using material density, target melting temperature, the target extrusion zone, an infrared thermometer, a cooling device, and n initial cables, n cooling cables are obtained. This embodiment of the invention uses an infrared thermometer to detect the cooling temperature in real time and adjusts the extrusion process of the cooling cables in the target extrusion zone in real time based on the cooling temperature, material density, and target melting temperature, ensuring that the obtained cooling cables meet the requirements and improving the product quality of the cables. For each of the n cooling cables, the following operations are performed: The cable diameter is measured using a laser diameter gauge; the diameter difference is calculated using the cable diameter and a preset target diameter. This embodiment of the invention uses a laser diameter gauge to inspect the cooling cables, facilitating the screening of substandard cooling cables in subsequent embodiments. The diameter difference is compared with a preset diameter difference threshold. If the diameter difference is less than or equal to the threshold, the cooling cable is considered a qualified cable, thus completing quality monitoring of cable production. This embodiment of the invention automatically screens qualified cooling cables by comparing the diameter difference and the diameter difference threshold, improving the automation level of the production process and thereby achieving quality monitoring of the cables. Therefore, this invention can improve the product quality of cables and reduce the scrap rate.
