Description

Technical Field

[0001] This application relates to the field of materials processing technology, specifically to a flattening assembly and a method for detecting the pressing thickness based on the flattening assembly. Background Technology

[0002] When it is necessary to detect the thickness of pressed material, the two most common methods are short-circuit thickness detection and laser thickness detection. Short-circuit thickness detection has drawbacks in terms of sensitivity and ease of adjustment, and suffers from insufficient detection accuracy. Laser sensors also have the problem of insufficient detection accuracy. Furthermore, these two detection methods are usually difficult to integrate with the components undergoing the pressing process; generally, the thickness of the material is measured separately after the pressing process is completed, making the operation cumbersome. Summary of the Invention

[0003] This application mainly provides a flattening component and a pressing thickness detection method based on the flattening component, which can realize real-time detection of material thickness changes during the material pressing process.

[0004] To solve the above-mentioned technical problems, one technical solution adopted in this application is: to provide a flattening component, including a pressing component, a fixing component, and a force sensor group. The pressing component is used to press against a material to reduce the thickness of the material. A fixing groove is formed on one side surface of the fixing component, and the fixing groove is used to accommodate the pressing component. The force sensor group is disposed in the fixing groove and connected to the pressing component, and is used to measure the force data of the pressing component. The force data is used to provide feedback on the change in the thickness of the material.

[0005] In one specific embodiment, the force sensor group includes a first sensor, which is disposed at the bottom of the fixing groove.

[0006] In one specific embodiment, the flattening assembly further includes an elastic pad disposed on the inner wall of the fixing groove and isolated between the pressing member and the inner wall of the fixing groove.

[0007] In one specific embodiment, the force sensor group includes a second sensor disposed on the side wall of the fixing groove and facing the pressing member.

[0008] In one specific embodiment, the flattening assembly further includes a pressure cap, which is detachably connected to the fixing member. The pressure cap is used to abut against the side surface of the pressing member facing out of the fixing groove to confine the pressing member within the fixing groove.

[0009] In one specific embodiment, the force sensor group includes a third sensor disposed on the side of the pressure cap facing the pressing member, for measuring the force of the pressing member abutting against the pressure cap; when the pressing member abuts against the material, the pressing member is subjected to a force exerted by the material along the depth direction of the fixing groove, and at this time the force of the pressing member abutting against the pressure cap measured by the third sensor decreases.

[0010] In one specific embodiment, the flattening assembly further includes a controller having a communication module for signal connection between the controller and the force sensor group. The controller is used to receive electrical signals sent by the force sensor group, convert the electrical signals into digital signals, and analyze the digital signals.

[0011] To solve the above-mentioned technical problems, another technical solution adopted in this application is: providing a pressing thickness detection method based on a flattening component, using the flattening component described in any of the above embodiments. The pressing thickness detection method includes: a measurement data acquisition step: acquiring measurement data from a force sensor group, the measurement data including force data collected by the force sensor group and the acquisition time of the force data; an analysis and judgment step: analyzing the measurement data to determine whether the real-time thickness of the material at the acquisition time can be calculated based on the measurement data; and a real-time thickness calculation step.

[0012] In one specific embodiment, the analysis and judgment step includes: comparing the measurement data with the operating parameter range of the flattening component; after the analysis and judgment step, the step further includes: generating an alarm message and controlling the flattening component to stop working in response to the measurement data being outside the operating parameter range; the real-time thickness calculation step includes: calculating the real-time thickness using the measurement data in response to the measurement data being within the operating parameter range.

[0013] In one specific embodiment, the step of calculating the real-time thickness using the measurement data includes: repeating the step of acquiring measurement data from the force sensor group at first intervals until the step of calculating the real-time thickness using the measurement data, so as to obtain multiple real-time thicknesses at different acquisition times; and generating a working status chart of the flattening component using the multiple real-time thicknesses, the multiple measurement data, and the multiple acquisition times.

[0014] The beneficial effects of this application are as follows: Unlike the prior art, in the embodiments of this application, a fixing groove for accommodating the pressing member is provided in the fixing member, thereby setting a force sensor group between the pressing member and the fixing groove. During the pressing process of the pressing member pressing the material, the force of the pressing material can be transmitted to the force sensor group through the pressing member. Thus, the force sensor group of the flattening assembly can be used to directly monitor the pressing process of the material in real time, achieving the technical effect of characterizing the material thickness using force data, without the need to remove the material from the structure of the flattening assembly for separate thickness measurement. Furthermore, while simplifying the material preparation and testing process, the measurement of force data can also achieve the effect of timely detection of anomalies, improving the usability of the flattening assembly.

[0028] To ensure product quality and consistency across all products, it is necessary to inspect the thickness of the embossed material on the production line. Common methods for embossing thickness include short-circuit thickness detection and laser thickness detection. However, short-circuit thickness detection suffers from limitations in sensitivity and ease of adjustment, resulting in insufficient detection accuracy. Laser sensors also exhibit insufficient accuracy. Furthermore, these two methods are typically difficult to integrate with the embossing equipment; generally, the material thickness can only be measured separately after the embossing process is complete, making the operation cumbersome and lacking real-time feedback on the embossing progress.

[0029] In order to improve or solve the above technical problems, the inventors of this application, after long-term research, have proposed at least the following embodiments.

[0030] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 1 This is a schematic diagram of the assembly structure of the flattening component provided in this application. Figure 2 This is a schematic diagram of the assembly structure of the flattening component provided in this application from another angle. Figure 3 This is a structural schematic diagram of the fastener provided in this application. Figure 4 This is an exploded structural diagram of the flattening assembly provided in this application. Embodiments of this application provide a flattening assembly 1 for pressing materials to form a shape. The flattening assembly 1 includes a pressing member 2, a fixing member 11, and a force sensor group 13.

[0031] The pressing member 2 is used to press against the material to reduce its thickness. A fixing groove 111 is formed on one side surface of the fixing member 11 for accommodating the pressing member 2. A force sensor group 13 is disposed within the fixing groove 111 and connected to the pressing member 2 to measure the force data acting on the pressing member 2. This force data can be used to provide feedback on changes in the material's thickness.

[0032] The force sensor assembly 13 may include at least one sensor, which is a force sensor, a device that can convert the magnitude of force into a corresponding electrical signal. Force sensors can detect mechanical quantities such as tension, strain, pressure, weight, torque, internal stress, and strain.

[0033] The force sensor may include at least one of strain tube sensors, diaphragm sensors, strain beam sensors, and combined sensors.

[0034] The structure provided in this embodiment utilizes a fixing groove 111 in the fixing member 11 to accommodate the pressing member 2. A force sensor group 13 can be installed between the pressing member 2 and the fixing groove 111. During the pressing process of the pressing member 2, the force of the pressing material is transmitted through the pressing member 2 to the force sensor group 13. This allows for real-time monitoring of the pressing process using the force sensor group 13 of the flattening assembly 1, achieving the technical effect of characterizing material thickness using force data. This eliminates the need to remove the material from the structure of the flattening assembly 1 for separate thickness measurement, reducing the workload of operators and improving the efficiency of the flattening assembly 1. Furthermore, while simplifying the material preparation and testing process, the force data measurement also enables timely detection of anomalies, improving the usability of the flattening assembly 1.

[0035] Optionally, the flattening assembly 1 may further include a support rod 17, which is used for transmission connection to the fixing member 11, and the support rod 17 and the fixing member 11 are relatively fixed. During the pressing process, the support rod 17 can support the pressing member 2 that is pressing against the material, maintaining pressing stability. Furthermore, the support rod 17 can drive a connected motor to move the pressing member 2 under the driving action of the motor, thereby realizing the material pressing process.

[0036] Optionally, the material of the pressing component 2 can be manganese steel, specifically manganese steel sheet 21. Manganese steel is a high-strength steel with good pressure-bearing properties, capable of withstanding harsh working conditions such as impact, extrusion, and material abrasion, thus making it suitable for use as the pressing component 2 as a pressing material.

[0037] See Figure 5 , Figure 6 , Figure 5 yes Figure 4 Schematic diagram of the cross-sectional structure at section AA. Figure 6 yes Figure 1 A cross-sectional view of section BB. In a specific embodiment of this application, the force sensor group 13 may include a first sensor 131, which is disposed at the bottom of the fixing groove 111.

[0038] To ensure structural stability and uniform force distribution, the flattening component 1 typically applies force to the material in the opposite direction of the depth F of the fixed groove. Therefore, by placing the first sensor 131 at the bottom of the fixed groove 111, the force applied by the pressing component 2 to the bottom of the fixed groove 111 can be effectively detected, thereby effectively feeding back the force data changes of the pressing material and thus enabling real-time characterization of the material thickness changes.

[0039] In one specific embodiment of this application, the flattening assembly 1 may further include an elastic pad 14. The elastic pad 14 may be disposed on the inner wall of the fixing groove 111 and isolated between the pressing member 2 and the inner wall of the fixing groove 111. This uniformly distributes the force applied by the pressing member 2 to the inner wall of the fixing groove 111. When the surface of the pressing member 2 facing the material experiences uneven force, the elastic pad 14 can evenly fix the pressure on all parts of the inner wall of the groove 111, thereby reducing damage to the fixing member 11 caused by excessive pressure in a single area and improving the stability of the flattening assembly 1.

[0040] Optionally, the elastic pad 14 can be made of urethane (polyurethane elastomer). Urethane is a new type of material with properties between plastics and rubber, possessing the rigidity of plastics and the elasticity of rubber. It has good strength, low compression deformation, and features cushioning, sound insulation, shock absorption, wear resistance, and high temperature resistance. It also has superior tensile strength, tear resistance, high elasticity, high pressure load resistance, and wear resistance, as well as good aging resistance and a long service life.

[0041] Optionally, the elastic pad 14 can be combined with the force sensor assembly 13 to facilitate their installation. For example, the force sensor assembly 13 can be embedded in the side of the elastic pad 14 facing the pressing member 2, so that the opposing surfaces of the force sensor assembly 13, the elastic pad 14, and the pressing member 2 can fit tightly together, improving the detection effect of the force sensor assembly 13 and maintaining the structural stability of the flattening assembly 1.

[0042] Optionally, the force sensor assembly 13 may include an elastic pad 14, which can undergo elastic deformation during the compression of the pressing member 2 and the inner wall of the fixing groove 111. Thus, the force on the elastic pad 14 can be detected by detecting the elastic deformation of the elastic pad 14, thereby characterizing the thickness change of the material.

[0043] In one specific embodiment of this application, the force sensor group 13 includes a second sensor 132, which is disposed on the side wall of the fixing groove 111 and faces the pressing member 2. When the reaction force of the material on the pressing member 2 is not along the depth direction F of the fixing groove, the second sensor 132 can measure part of the reaction force.

[0044] This allows for the detection of any abnormalities during the pressing process by monitoring the pressure exerted by the pressing component 2 on the inner wall of the fixing groove 111. These abnormalities may include the pressing component 2 becoming misaligned, the presence of foreign objects in the fixing groove 111, foreign objects at the contact surface between the pressing component 2 and the material, or unstable material fixation. Using the second sensor 132 to acquire the pressure of the pressing component 2 on the side wall of the fixing groove 111 provides a more accurate understanding of the pressing process, thereby improving the accuracy of the pressed thickness characterization and effectively detecting abnormalities.

[0045] See Figure 7 , Figure 7 This is another structural schematic diagram of the flattening assembly provided in this application. In a specific embodiment of this application, the flattening assembly 1 may further include a pressure cap 15, which is detachably connected to the fixing member 11. The pressure cap 15 is used to press against the side surface of the pressing member 2 facing out of the fixing groove 111, so as to confine the pressing member 2 within the fixing groove 111. With the structure provided in this embodiment, by using the pressure cap 15 to confine the pressing member 2 within the fixing groove 111, the position of the pressing member 2 can be effectively controlled, and the stability of the material pressing process fed back by the force sensor group 13 can be improved.

[0046] Optionally, the pressure cap 15 can be an annular pressure cap 15, wherein the diameter of the hole in the annular pressure cap 15 is smaller than the diameter of the pressing member 2, so that while limiting the pressing member 2, part of the pressing member 2 can be exposed through the annular pressure cap 15 to contact the material.

[0047] Optionally, the flattening assembly 1 may further include a movable screw 3, a second mating hole 32 may be provided in the pressure cap 15, and a first mating hole 31 may be provided in the fixing member 11. The movable screw 3, the first mating hole 31, and the second mating hole 32 are arranged correspondingly. The movable screw 3 can screw the first mating hole 31 and the second mating hole 32, thereby connecting the pressure cap 15 and the fixing member 11, and thus limiting the pressing member 2.

[0048] In one specific embodiment of this application, the force sensor group 13 may include a third sensor 133. The third sensor 133 is disposed on the side of the pressure cap 15 facing the pressing member 2, and is used to measure the force of the pressing member 2 abutting against the pressure cap 15.

[0049] When the pressing member 2 comes into contact with the material, it is subjected to a force F exerted by the material along the depth direction of the fixing groove. At this time, the force from the pressure cap 15 on the pressing member 2 in this direction decreases, and therefore the contact force between the pressing member 2 and the pressure cap 15 measured by the third sensor 133 decreases. In this way, the force data during the material pressing process can also be measured, further providing feedback on the material thickness change and improving the accuracy of material thickness monitoring.

[0050] In one specific embodiment of this application, the flattening assembly 1 further includes a controller, which has a communication module 161. The communication module 161 is used to signal connect the controller and the force sensor group 13. The controller receives electrical signals sent by the force sensor group 13, converts these electrical signals into digital signals, and then analyzes the digital signals. By setting the controller, the electrical signals output by the force sensor group 13 can be effectively converted into analyzable digital signals for analysis, thereby enabling the monitoring of material thickness.

[0051] In the case where a third sensor 133 is installed on the pressure cap 15, since the pressure cap 15 and the fixing member 11 of the flattening assembly 1 are detachably connected, the controller's communication module 161 can be installed at two locations, one on the pressure cap 15 and the other on the fixing member 11, to acquire electrical signals output by the sensors at different positions. Optionally, the communication module 161 may include a wireless communication module and / or a wired communication module.

[0052] See Figure 8 , Figure 8 This is a schematic flowchart of the pressing thickness detection method based on a flattening component provided in this application. This application also provides a pressing thickness detection method based on a flattening component 1, characterized in that it employs the flattening component 1 described in any of the above specific embodiments.

[0053] In this embodiment, the execution subject of the pressing thickness detection method based on the flattening component 1 can be the controller of the flattening component 1. The pressing thickness detection method based on the flattening component 1 can be stored in the controller or in the memory connected to the controller in the form of device software. The controller runs the device software as a device to execute the pressing thickness detection method based on the flattening component 1.

[0054] The pressing thickness detection method based on the flattening component 1 may specifically include the following steps:

[0055] S100 acquisition of measurement data steps: acquire measurement data from force sensor group 13. The measurement data includes force data collected by force sensor group 13 and the acquisition time of the force data.

[0056] The controller acquires measurement data from the force sensor group 13 via a communication module 161 connected to the force sensor group 13. This measurement data may include force data collected by the sensors in the force sensor group 13, and the time at which this force data was collected. The measurement data can be transmitted to the controller in the form of electrical signals via the communication module 161.

[0057] S200 analysis and judgment steps: Analyze the measurement data and determine whether the real-time thickness of the material at the time of acquisition can be calculated based on the measurement data.

[0058] The controller converts the measurement data into an analyzable form, such as converting electrical signal measurement data into digital signals, and then analyzes it to determine whether the measurement data can be used as a basis for judgment when calculating the real-time thickness of the material at the acquisition time.

[0059] S300 real-time thickness calculation steps.

[0060] The controller calculates the real-time thickness to obtain the material's real-time thickness at the time of acquisition.

[0061] The method provided in this embodiment utilizes a fixing groove 111 in the fixing member 11 to accommodate the pressing member 2. A force sensor group 13 is set between the pressing member 2 and the fixing groove 111. During the pressing process of the pressing member 2 pressing the material, the force of the pressing material is transmitted through the pressing member 2 to the force sensor group 13. The force sensor group 13 of the flattening assembly 1 can directly monitor the pressing process of the material in real time, eliminating the need to remove the material from the structure of the flattening assembly 1 for thickness measurement. This reduces the workload of the operators of the flattening assembly 1 and improves its working efficiency. Furthermore, it allows for analysis of whether the force data can be used as a calculation basis, thereby achieving the technical effect of characterizing material thickness using force data. Moreover, the method provided in this embodiment simplifies the material preparation and testing process while also achieving timely anomaly detection, improving the usability of the pressing thickness detection method based on the flattening assembly 1.

[0062] In one specific embodiment of this application, step S200, the analysis and judgment step, may include: comparing the measured data with the operating parameter range of the flattening component 1. This determines whether the measured data is normal data within the operating parameter range of the flattening component 1.

[0063] At this point, the S200 analysis and judgment step may further include: the equipment software responding to the measurement data being outside the operating parameter range generates an alarm message and controls the flattening assembly 1 to stop working. When the measurement data is abnormal, it is very likely that there is an abnormality inside the flattening assembly 1, between the flattening assembly 1 and the material, and / or at the material, such as the presence of foreign objects. In this case, the alarm message can serve as a reminder to the relevant technical personnel of the flattening assembly 1, and the automatic shutdown of the flattening assembly 1 can protect the flattening assembly 1, thereby promptly notifying the relevant technical personnel to come and repair the abnormality, and reducing the probability of the flattening assembly 1 being damaged due to abnormalities or producing a large number of non-compliant products, thus improving the stability and availability of the flattening assembly 1.

[0064] In this case, the S300 real-time thickness calculation step may specifically include: the controller responding to the measurement data being within the range of the operating parameters, using the measurement data to calculate the real-time thickness, thereby obtaining a real-time thickness that effectively characterizes the material at the time of acquisition.

[0065] In a specific embodiment of this application, the controller can actually cyclically execute the pressing thickness detection method based on the flattening component 1, thereby acquiring force data at multiple acquisition times, and then calculating the real-time thickness at multiple acquisition times, and forming force change curves and / or material thickness change curves at different acquisition times.

[0066] After calculating the real-time thickness using measurement data, the following steps may be included:

[0067] S400: The controller repeatedly executes steps S100 to S300 at the first time interval, such as executing the steps of acquiring measurement data from the force sensor group 13 and calculating the real-time thickness using the measurement data, so as to obtain multiple real-time thicknesses at different acquisition times.

[0068] S500: The controller uses multiple real-time thicknesses, multiple measurement data, and multiple acquisition times to generate a chart showing the working status of the flattening component 1.

[0069] Specifically, the working status chart can include a force change curve, which reflects the changes in force applied to the material during the pressing process. The force change curve can show the changes in force applied to the material by the flattening component 1 during a single pressing process, or the cyclical nature of the force applied by the flattening component 1 during multiple pressing processes, effectively providing feedback on the working status of the flattening component 1.

[0070] Optionally, the working status chart may include a thickness variation curve, which can reflect the thickness variation of the material during a single material pressing process, or reflect the thickness variation of the material during multiple material pressing processes. This can effectively reflect the working status of the flattening component 1 and help the user understand the processing status of the material.

[0071] Optionally, the status chart may include only the data from the ten most recent acquisition times so that users can know the latest status of the flattening component 1.

[0072] In this embodiment of the application, the method of calculating the thickness of the material using force data may include a lookup table method. Specifically, multiple standard experiments can be conducted beforehand using the flattening component 1 to test the pressing process of the material, recording the force data at multiple sampling moments during the pressing process, and manually measuring the material thickness at these moments. These sampling moments belong to different material pressing stages.

[0073] Subsequently, a parameter change table or curve can be established using the force data, material thickness, and the material pressing stage at which the data was collected, to establish a correlation among the three. The parameter change table or curve obtained from multiple standard tests can be converted into an average parameter change table or curve. During subsequent material pressing processes, the controller can obtain the corresponding material thickness from the average parameter change table or curve based on the measured force data, and then calculate the real-time material thickness at that collection moment.

[0074] Furthermore, by statistically analyzing the force data from standard tests, the range of force data variation during the normal material pressing process can be measured. Force data exceeding this range can then be identified as abnormal force data, thus achieving the purpose of detecting whether the flattening component 1 is functioning normally.

[0075] The above description is only a partial embodiment of this application and does not limit the scope of protection of this application. Any equivalent device or equivalent process transformation made based on the content of this application specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the scope of patent protection of this application.
