Description

Technical Field

[0001] The present application relates to the technical field of glass fiber cloth production and processing, and in particular to a tension control device and a method for preparing glass fiber cloth using the same. Background Art

[0002] Electronic-grade glass fiber cloth is the base material used to produce and process copper-clad laminates. It is made by drawing high-purity glass into fibers and then undergoing textile processing.

[0003] As the requirements for various electronic devices increase, the requirements for circuit boards and circuit board substrates are also getting higher and higher. Among them, the requirements for glass fiber cloth are: uniform mechanical properties - uniform tensile strength, high tear strength, good dimensional stability, good wrinkle resistance, consistent surface flatness, etc.

[0004] In order to achieve the above-mentioned effects, in addition to adjusting the warp and weft density, parameters such as fiber tension need to be adjusted during the weaving process of the glass fiber cloth. However, many existing textile machines rely on imports, and the structures of domestic alternative equipment are relatively similar. In addition, the equipment is costly, and often has not been improved much for many years or even longer. The equipment is complex, and the adjustment of the above-mentioned parameters requires strong professional dependence, and it cannot be operated by non-experienced workers and industry insiders. As a result, major manufacturers either have resident professionals or hire external professionals every time they encounter a demand, which is not conducive to the orderly advancement of production and processing. Therefore, this application proposes a new technical solution. Summary of the invention

[0051] The following is combined with Figure 1-7 This application is described in further detail.

[0052] The embodiment of the present application discloses a tension regulating device.

[0053] Reference Figure 1 The tension control device includes a factory-end device and a mobile-end device, wherein the factory-end device refers to a device deployed in each glass fiber cloth production and processing plant, and the mobile-end device refers to a device "carried" by designated professionals. The former collects on-site data and modulation parameters in the factory, and the latter displays the on-site situation to the user at the remote end and sends instructions to the device on the factory side for control according to user requirements. Therefore, after applying this application, even if the modulation of the glass fiber cloth weaving equipment is still relatively professional, because the staff can be away from the factory site, the weaving process modulation is also relatively convenient, which helps to improve the convenience of production and processing of glass fiber cloth and meet the processing needs of high-quality glass fiber cloth.

[0054] Reference Figure 2 The above-mentioned plant-side device includes a sensing mechanism 1, a plant-side controller 2, a communication module 3 and a regulating mechanism 4, wherein the structure of the regulating mechanism 4 is the main carrier, so the following starts with the regulating mechanism 4:

[0055] Reference Figure 1 and Figure 3 The adjusting mechanism 4 includes an adjusting wheel 41, a guide wheel 42 and a wheel cup 43. The wheel cup 43 is fixed on a weaving machine, such as a wire rack support of a weaving machine. It can be understood that the fibers are woven into wires, so this embodiment is no longer described with a single glass fiber.

[0056] In this embodiment, a cup cavity is formed inside the wheel cup 43, and the upper part of the cup cavity is opened for other structural components to enter and exit. A cup cover 431 is fixed to the upper opening of the cup cavity by bolts, and a cup cover hole is opened in the center of the cup cover 431. The adjusting wheel 41 forms a wire groove around the central axis and a rotating shaft 1 411 is fixed to the central axis. The rotating shaft 1 411 penetrates the cup cover hole and is rotatably connected to the cup cover 431, that is, the rotation of the adjusting wheel 41 is realized; the cup cover 431 is made of ceramic, which is insulated and has high strength.

[0057] Reference Figure 4 A section of the rotating shaft 411 located in the wheel cup 43 is fixed with a coil group (the winding method refers to the winding of the motor and the generator, and can be simply considered as the C line); a small current release unit 44 is arranged on the outside of the cup cover 431, and the small current release unit 44 is in rotational contact with the rotating shaft 411 and is electrically connected to the coil group.

[0058] Two electromagnets 45 are fixed in the cup cavity of the wheel cup 43, and the two electromagnets 45 are symmetrically distributed on both sides of the rotating shaft 411. The electromagnets 45 are electrically connected to the factory-end controller 2 and the magnetic force is controllable. The magnetic force is controlled, for example: the electromagnet 45 is a DC electromagnet, which controls a sliding rheostat, and the sliding rheostat is connected in series to the power supply circuit of the electromagnet 45; if the sliding rheostat is in the form of a potentiometer, it can be equipped with a small servo reduction motor to drive its rotation to change the resistance.

[0059] During use, the longitude and latitude lines pass around the adjustment wheel 41, for example:

[0060] In the first method, the warp and weft threads are pulled out from the reel on the thread rack, wound around the adjusting wheel 41 once, and then pulled to the subsequent process position;

[0061] The second method is to fix a top shaft at the top center of the adjusting wheel 41, fix a bobbin on the top shaft, and the warp and weft threads are wound around the bobbin. After being pulled out from the bobbin, they are wound around the adjusting wheel 41 once and then pulled to the subsequent process position.

[0062] Under the above premise, during the weaving process, the adjusting wheel 41 will be pulled along by the continuous pulling of the wire. Due to the structure in the wheel cup 43, the staff can determine the resistance encountered when the adjusting wheel 41 rotates by controlling the magnetic force of the electromagnet 45, thereby changing the tension of the wire (i.e., glass fiber) during the weaving process.

[0063] In the process of generating the rotation resistance of the adjusting wheel 41, the coil group on the rotating shaft 1 411 will generate current due to cutting the magnetic lines of force. However, the resistance is relatively small, resulting in a small induced current. Moreover, the current is also unstable due to the need to adjust the resistance. Therefore, the generated current cannot be directly used to charge the battery, etc. However, it is relatively wasteful if it is directly released. Therefore, the following configuration is made in this embodiment:

[0064] The tiny current release unit 44 includes a brush and an electrochromic glass; a section of the rotating shaft 411 outside the wheel cup 43 is fixed with two conductive rings 441, and the two ends of the wire in the coil group are electrically connected to the conductive rings 441 along the long grooves on the outer wall of the rotating shaft 411; an insulating seat is fixed outside the cup cover 431, the brush fixes the insulating seat and contacts the corresponding conductive ring 441, and the electrochromic glass is adhered to the cup wall of the wheel cup 43 and electrically connected to the brush.

[0065] According to the above arrangement, the current generated in the wheel cup 43 can be led out and sent to the electrochromic glass. Since the electrochromic glass can change even with a current of milliamperes, it can be driven by the current generated by the tension adjustment. Moreover, due to the visual characteristics of the electrochromic glass, the staff can also diagnose whether there is a fault in the wheel cup 43 by observing the performance of the electrochromic glass during tension adjustment, thereby facilitating maintenance work.

[0066] After the longitude and latitude lines are drawn out from the adjusting wheel 41 on the wheel cup 43, the longitude and latitude lines are guided to move to the subsequent position by the guide wheel 42. The function of the guide wheel 42 is to allow the lines to leave the adjusting wheel in time and guide the direction of the lines. The guide wheel 42 can be one or more. The guide wheel 42 is fixed with the central axis to the second rotating shaft, and the second rotating shaft is rotatably connected to an L-shaped structural rod fixed outside the wheel cup 43. The longitude and latitude lines pulled out from the adjusting wheel 41 bypass the guide wheel 42.

[0067] The sensing mechanism 1 includes a sensing column 11, a force measuring wheel 12 and a pressure sensor 13.

[0068] The sensing column 11 is fixed by the weaving machine structure near the wheel cup 43, the ground, etc.; taking the horizontal movement of the longitude and latitude lines sent from the guide wheel 42 as an example:

[0069] The sensing column 11 is located on the side of the longitude and latitude lines, and the pressure sensor 13 is inserted into the preset slot on the side of the sensing column 11; the sensing surface of the pressure sensor 13 faces outward, and the sensing surface is fixed to the force measuring seat 14; the force measuring wheel 12 is rotatably connected to the force measuring seat 14, and the force measuring wheel 12 can be made of ceramic, and its wheel surface contacts the longitude and latitude lines and the rotation direction is parallel to the section of the longitude and latitude lines.

[0070] It should be noted that the force measuring wheel 12 should be able to lift the warp and weft lines in contact, so that they deviate from the expected route when there is no force measuring wheel 12, that is, the line connecting the force measuring wheel 12 and the guide wheel 42 forms an angle with the direction of the warp and weft lines when there is no force measuring wheel. According to the above settings, the change of the tension of the warp and weft lines will cause the detection value of the pressure sensor 13 to change.

[0071] The pressure sensor 13 is electrically connected to the factory-side controller 2, which is installed in a control cabinet near the weaving machine, and is one-to-many; the communication module 3 is electrically connected to the factory-side controller 2, and the communication module 3 can be a 3G / 4G / 5G module for networking for wireless data interaction.

[0072] When in use, the factory-side controller 2 sends the detection value of the pressure sensor 13 to the mobile device; it can be understood that any pressure sensor 13 has its own ID or identification number, and is bound to the corresponding longitude and latitude line number / position, and bound to the corresponding production line / factory, so that it can be reasonably called and analyzed on the mobile device.

[0073] Reference Figure 1 and Figure 5 In another embodiment of the device, the mobile terminal device includes a body 5, and the body 5 includes a base 51 and a mobile terminal controller 52 integrated in the base 51, a communication module 2 53, a mobile power supply and a touch display 54.

[0074] The base 51 is a box structure in this embodiment and is made of high-strength plastic, which reduces the weight as much as possible while ensuring a certain structural strength. The communication module 2 53 and the touch display 54 are electrically connected to the mobile terminal controller 52, and the communication module 2 53 is on the inside, and the touch display 54 is exposed to the outside after being embedded and installed, so that the user can operate it; the mobile power supply supplies power to the power structure on the mobile terminal device.

[0075] Reference Figure 6 and Figure 7 The mobile terminal device further includes a routing simulation mechanism 6, which is mounted on the base 51 and electrically connected to the mobile terminal controller 52. The routing simulation mechanism 6 includes a plurality of loop routing groups 61, a second sensing mechanism 62 and a movable driving mechanism 63. Specifically:

[0076] 1) The circular wiring group 61 includes two groups of winding and releasing wire units 611 and a simulation wire. The winding and releasing wire unit 611 includes a wire wheel, a wire wheel shaft and a wire wheel seat. The wire wheel seat is fixed in the machine base 51. The wire wheel is fixed to the wire wheel shaft with the same central axis. The wire wheel shaft is rotatably connected to the wire wheel seat. A wire groove is formed on the wire wheel.

[0077] The two groups of retractable and retractable wire units 611 are symmetrically arranged, and two ends of the simulation wire are respectively fixed in the wire grooves of the wire wheels of the two groups of retractable and retractable wire units 611 .

[0078] When in use, one retractable wire unit 611 reels the simulation wire, and another symmetrical retractable wire unit 611 releases the simulation wire; a plurality of groups of circulating wire routing groups 61 are arranged along the width direction of the machine base 51 .

[0079] 2) The movable driving mechanism 63 includes two sets of driving units 631 and a lateral movement unit 632. The driving unit 631 includes a servo motor, a long shaft, a driving gear and a driven gear;

[0080] The transverse movement unit 632 can be a small linear motor and a screw slide, which is fixed to the machine base 51; the servo motor is fixed to the slider of the transverse movement unit 632, and the long axis and the center axis are fixed to the output shaft of the servo motor. The length direction of the long axis is perpendicular to the distribution direction of the same pair of take-up and pay-out units 611 and is close to the take-up and pay-out unit 611 on one side. The long axis is also radially fixed and axially slidable by slidingly connecting to the bearing seat of the machine base 51; the number of driving (bevel) gears is the same as the number of circulating wiring groups 61, and the driving gears are fixed to the long axis and correspond one-to-one to each group of circulating wiring groups 61; the number of driven gears is the same as the driving gears, and the driven gears are fixed to the reel shaft of the take-up and pay-out unit 611 and correspond one-to-one to each driving gear; the two groups of driving units 631 are respectively close to the two groups of take-up and pay-out units 611 of the same circulating wiring group 61.

[0081] When in use, the active gear of one set of drive units 631 meshes with the corresponding driven gear, and the active gear of the other set of drive units 631 is separated from the driven gear, then all the simulated lines can be driven to move toward one side by the servo motor; after the simulated line has been running for a period of time, the conditions of the above two sets of drive units 631 are swapped to allow the simulated line to move in the opposite direction; the above cycle can continuously perform simulated wiring to meet the continuous use needs of continuous users. It should be known that when the factory end weaves, there are not only a few lines, but dozens or hundreds of lines, and the mobile terminal device cannot be made very large because it needs to be convenient. Therefore, this device considers simulating a part of the situation on site at a time, and multiple cycles can simulate all of the situation on site, so that professional staff can understand the actual situation of the factory by touching the simulated line on the mobile terminal device with their fingers, and make relatively accurate tension adjustments.

[0082] At the same time, because when one end of the loop wiring assembly 61 actively rotates, the driving gear and the servo motor at the other end will retreat, so less obstruction interference is generated and the tension adjustment is easier.

[0083] How to complete the simulation routing will be explained later, so I will not go into details here.

[0084] 3) The sensing mechanism 62 includes a force measuring unit 621 and an electric cylinder 622. The number of force measuring units 621 is the same as the number of simulation lines and corresponds one to one. The electric cylinder 622 is a small electric cylinder, and the number is the same as the force measuring unit 621. The electric cylinder 622 is fixed to the machine base 51, and the telescopic end is fixed to the force measuring unit 621. The force measuring unit 621 includes a force measuring wheel 2 and a pressure sensor 2; the pressure sensor 2 is fixed to the telescopic rod end of the electric cylinder 622, and the sensing surface of the pressure sensor 2 is connected to the force measuring wheel 2 through the corresponding force measuring seat, and the force measuring wheel 2 contacts the simulation line.

[0085] According to the above settings, on the one hand, the detection value of pressure sensor 2 can be used to evaluate whether the tension of the simulation line is the same as that of the factory site, and after meeting the standard, professionals can perform touch perception analysis; on the other hand, the tension of the simulation line can now be achieved not only by changing the speed of the servo motor, but also by changing the position of the force measuring wheel 2 through the extension and retraction of the electric cylinder 622. The operation mode is flexible and diverse to meet various usage requirements.

[0086] The above-mentioned pressure sensor 2, electric cylinder 622, servo motor, and lateral movement unit 632 are respectively electrically connected to the mobile end controller 52 for automatic control.

[0087] In one embodiment of the device, the body 5 (i.e., the mobile terminal controller 52) is configured to: control the routing simulation mechanism to perform simulation actions according to the sensing data of the latitude and longitude lines on site acquired by the factory terminal device, specifically:

[0088] 1. Identify and classify the perceived data to obtain real-time information on all the longitude and latitude lines under supervision of any factory / production line.

[0089] It is known that the perception data is measured by a pressure sensor 13, which has corresponding ID, factory / production line, longitude and latitude lines and other binding information. Therefore, the mobile terminal controller 52 can sort out the corresponding data according to the factory / production line and wait for calling.

[0090] 2. Determine the number of longitude and latitude lines under supervision based on real-time information, and combine the current record of the maximum number of lines that can be simulated at a time on the mobile terminal to determine the number of times to be simulated, and establish a one-to-one correspondence between the number of simulations and the corresponding longitude and latitude lines.

[0091] Among them, the currently recorded maximum number of lines that can be simulated at a single time on the mobile terminal is determined by the staff's own input, or it can be the number of loop routing groups 61 of the device that are currently functioning normally. For example: the number is 20 groups, and the number of longitude and latitude lines under supervision is 105, then 105 / 20, the integer 5 and the remainder are obtained, so the number of simulations to be performed is 6 times, and 20 of the 105 longitude and latitude lines are divided into 5 parts, and the remaining 5 are used as one part, which are allocated to 6 simulations respectively.

[0092] 3. If a user's factory-side data viewing request is received, the factory / production line name in the request is identified and the corresponding real-time information is called for display.

[0093] The request is input by the user through the touch display 54. After the factory-side data viewing request is input, the staff can view the weaving data at the factory site through the touch display screen to compare with previous data and judge whether the tension needs to be adjusted based on experience.

[0094] If a factory data simulation request is received from the user, the factory / production line name in the request is identified, and the corresponding real-time information, the number of times to be simulated, and the longitude and latitude lines corresponding to the number of simulations are called, and the various components of the routing simulation mechanism are sequentially controlled to implement the simulation.

[0095] Example: If the request is a simulation request for production line A, the real-time information of production line A, the number of times to be simulated, and the longitude and latitude lines corresponding to the number of simulations will be called;

[0096] First, the loop routing group 61 in the device is initialized;

[0097] Secondly, read the real-time information of the first round of simulation, control a servo motor to rotate, and read the current detection value of the second pressure sensor, and compare it with the corresponding value in the real-time information; if they are different, automatically control the servo motor to change the speed or the electric cylinder 622 to extend and retract according to the instructions of the staff, until the detection value of the second pressure sensor is the same as the corresponding value in the real-time information, and the touch display 54 pops up a finger touch perception prompt, and displays the production line and longitude and latitude information corresponding to the current round of simulation;

[0098] The servo motor stops when the rotation reaches the preset maximum value; it moves away, and another servo motor rotates in the opposite direction to pull the simulation line to move;

[0099] Repeat the above steps until the staff actively determines to proceed to the next round of simulation or ends the simulation;

[0100] Finally, after the simulation is completed, the user is requested to fill in the tension control parameters.

[0101] In another embodiment of the device, the factory-side device is configured to control the regulating mechanism to perform actions according to user feedback after the user performs a simulation action on the mobile device.

[0102] The user feedback includes data input into the mobile device after the user touches and perceives the simulation content of the routing simulation mechanism; that is, the above tension control parameter, adjustment example:

[0103] The tension control parameter is the detection value of a pressure sensor 13 corresponding to a set of longitude and latitude lines. If the new pressure is greater than before, the electromagnet 45 is controlled to increase the magnetic force until the pressure reaches the standard.
