Description

Technical Field

[0001] This invention relates to the field of conductive sealing strip production, and more particularly to a multi-functional device for conductive cloth wrapping and double-sided adhesive bonding of soft sealing strips. Background Technology

[0002] Conductive sealing strips are functional sealing strips that combine sealing performance with conductive / electromagnetic shielding. Their core feature is the addition of conductive agents or composite conductive materials to an elastic substrate (such as silicone rubber) to control current, static electricity, and electromagnetic waves, while simultaneously meeting the sealing and protection requirements of equipment. They are widely used in fields with high requirements for electromagnetic compatibility and environmental protection, such as communication equipment, 5G construction, automotive electronics, and medical equipment.

[0003] For example, the invention patent with application number CN202111510408.X discloses a conductive cloth coating device for rubber sealing strips, which belongs to the field of coating equipment technology. It includes an adhesive applicator installed on a workbench for applying adhesive to the surface of the sealing strip; and a baking oven installed on the workbench for baking the adhesive-coated sealing strip.

[0004] The above cases still have the following shortcomings: For example, during the process of coating conductive cloth with silicone rubber, the conductive cloth is relatively soft, making it difficult to maintain a constant tension value during transportation. This is especially true during equipment operation, when sudden acceleration or deceleration occurs. Due to inertia, the conveyor rollers transporting the conductive cloth cannot easily adjust the tension value quickly, which can easily lead to uneven coating of the conductive cloth onto the sealing strip and reduce the sealing performance of the conductive sealing strip.

[0005] To address these issues, this invention proposes a multifunctional device for covering a soft sealing strip with conductive cloth and applying double-sided adhesive to solve the aforementioned problems. Summary of the Invention

[0006] To achieve the above objectives, the technical solution adopted by the present invention is: a conductive cloth coating device for a soft sealing strip, comprising: The machine tool has a covering fixture at its top, and the covering fixture is provided with multiple sets of guide modules for guiding and covering the conductive cloth and sealing strip. A traction mechanism, which is used to pull the covered conductive sealing strip; An unwinding roller is rotatably connected to a machine tool, and the conductive cloth is wound around the unwinding roller. A tension detection mechanism, used to detect the tension value of the conductive cloth; Two drive arc-shaped grooves are arrayed on the rotating shaft of the unwinding roller. A drive ring is slidably connected to the rotating shaft of the unwinding roller. A first sliding pin is symmetrically fixedly connected inside the drive ring. The first sliding pin is slidably connected inside the drive arc-shaped groove. A connecting ring is rotatably connected to the outer wall of the drive ring. Electric cylinders are symmetrically arranged on the side wall of the connecting ring. The electric cylinders are fixedly connected to the machine tool. The telescopic end of the electric cylinder is fixedly connected to the connecting ring. The controller controls the extension and retraction of the electric cylinder based on the tension value detected by the tension detection mechanism, so that the first sliding pin in the drive ring slides along the drive arc groove to drive the collecting roller to rotate and adjust the tension of the conductive cloth.

[0007] Preferably, the tension detection mechanism includes: Two mounting frames are symmetrically and fixedly connected to the machine tool. A fixing frame is slidably connected inside the mounting frame. A pressure sensor is installed inside the mounting frame to detect the pressure value of the fixing frame. Two tension rollers, which are symmetrically rotated and connected to a fixed frame, are used to stretch the conductive cloth.

[0008] Preferred options also include: A folding and turning frame is rotatably connected to a covering tooling table. Several first pressure rollers are rotatably connected in an array on the folding and turning frame. The first pressure rollers are located above the sealing strip. A turning roller is rotatably connected to the end of the folding and turning frame. The turning roller is located below the sealing strip. A servo motor is fixedly connected to the bottom of the covering fixture. The output shaft of the servo motor is fixedly connected to the rotating shaft of the folding and flipping frame. The controller controls the servo motor to rotate based on the pressure value detected by the pressure sensor. When the pressure value increases or decreases, the controller controls the servo motor to rotate, driving the folding and flipping frame to flip. The sealing strip is moved upward by the actuating roller, so that the sealing strip is separated from the conductive cloth.

[0009] Preferred options also include: Two slids are symmetrically opened on the covering fixture table. A U-shaped bracket is slidably connected in the slid. A second pressure roller is symmetrically arranged at the top of the U-shaped bracket. A sliding seat is vertically slidably connected to the bottom of the U-shaped bracket. The sliding seat is slidably connected to the bottom of the covering fixture table. A guide groove is formed on the inner side wall of the slide groove. The guide groove includes a first inclined groove and a straight groove. A second sliding pin is fixedly connected to the side wall of the U-shaped bracket. The second sliding pin is slidably connected in the guide groove. A drive mechanism is provided to drive the sliding seat to move, so that the U-shaped bracket moves along the guide groove trajectory.

[0010] Preferably, the drive mechanism includes: Two drive plates are symmetrically fixedly connected to the sliding seat, and the sidewalls of the drive plates are provided with second inclined grooves. A connecting plate, one end of which is fixedly connected to the rotating shaft of the folding and flipping frame, and the other end of which is fixedly connected to a third sliding pin, which is slidably connected in the second inclined groove.

[0011] Preferably, the second pressure roller and the U-shaped bracket are connected by a one-way bearing.

[0012] Preferably, the traction mechanism includes two traction roller groups, which are symmetrically rotatably connected to the machine tool, and the traction roller groups are driven by a drive motor.

[0013] Preferably, it also includes a take-up roller, which is rotatably connected to the machine tool for collecting waste paper on the conductive cloth, and the take-up roller and the unwinding roller are connected by a synchronous belt via a pulley.

[0014] Preferably, it also includes a guide wheel assembly, which is rotatably connected to the machine tool and is used to guide the conductive cloth to the covering fixture.

[0015] The present invention also provides a double-sided adhesive bonding device, including the conductive cloth covering device as described above, and further comprising: The adhesive application platform is installed on the machine tool. The side wall of the adhesive application platform is equipped with a suction nozzle, which is located below the conductive sealing strip. The suction nozzle absorbs dust and impurities on the conductive adhesive strip, ensuring that the double-sided tape can fully adhere to the sealing strip during the application process. Compared with the prior art, the present invention has the following beneficial effects: I. This invention, by setting up a driving arc groove, a driving ring, and a connecting ring, detects the tension value of the conductive cloth through a tension detection mechanism during the rotation of the unwinding roller. If the tension value increases or decreases, the driving ring slides along the rotating shaft of the unwinding roller. Under the guidance of the driving arc groove, the unwinding roller rotates in the forward or reverse direction, causing the unwinding roller to tighten excess conductive cloth or loosen more conductive cloth, thereby ensuring the flatness of the conductive cloth on the wrapping fixture and improving the sealing performance of the conductive sealing strip.

[0016] II. This invention, by setting up a folding and flipping frame, a first pressure roller, and a pushing roller, when the pressure value detected by the pressure sensor is not at the specified threshold, the controller controls the servo motor to rotate, driving the folding and flipping frame to flip. The pushing roller pushes the sealing strip upward, causing the sealing strip to leave the conductive cloth from above, thus separating the two. This avoids interference between the sealing strip and the conductive cloth during the adjustment of the conductive cloth tension, and helps to restore the originally uneven conductive cloth to a flat state. When the pressure value returns to the threshold, the folding and flipping frame flips back to its original position, and the first pressure roller presses the conductive cloth and the sealing strip together.

[0017] Third, during the process of the folding and flipping frame flipping and moving the sealing strip away from the conductive cloth, the connecting plate will flip synchronously with the folding and flipping frame, so that the third sliding pin slides along the second inclined groove. Driven by the second inclined groove, the sliding seat drives the U-shaped bracket to slide along the groove, so that the second sliding pin slides along the guide groove. The second sliding pin first slides along the first inclined groove and then enters the straight groove. Driven by the first inclined groove, the U-shaped bracket drives the second pressure roller to move downward first. After the second pressure roller moves to the top surface of the conductive cloth, the second pressure roller rolls along the edge area of ​​the conductive cloth to further smooth out the uneven areas, further improve the flatness of the conductive cloth, and improve the sealing performance of the conductive sealing strip.

[0020] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0021] like Figures 1 to 6 The conductive cloth covering device for a soft sealing strip shown includes: Machine tool 1, with a covering fixture 2 at the top of the machine tool 1, and multiple sets of guide modules 3 on the covering fixture 2 for guiding and covering the conductive cloth and sealing strip; The traction mechanism is used to pull the covered conductive sealing strip. Unwinding roller 8, conductive cloth unwinding roller 8 is rotatably connected to machine tool 1, and conductive cloth is wound on unwinding roller 8; Tension testing mechanism, used to detect the tension value of conductive cloth; Two drive arc grooves 9 are arrayed on the rotating shaft of the unwinding roller 8. A drive ring 10 is slidably connected to the rotating shaft of the unwinding roller 8. A first sliding pin 11 is symmetrically fixedly connected inside the drive ring 10. The first sliding pin 11 is slidably connected inside the drive arc groove 9. A connecting ring 12 is rotatably connected to the outer wall of the drive ring 10. Electric cylinders 13 are symmetrically arranged on the side wall of the connecting ring 12. The electric cylinders 13 are fixedly connected to the machine tool 1. The telescopic end of the electric cylinder 13 is fixedly connected to the connecting ring 12. Controller 14 controls the extension and retraction of electric cylinder 13 based on the tension value detected by the tension detection mechanism, causing the first sliding pin 11 in the drive ring 10 to slide along the drive arc groove 9, thereby driving the collecting roller to rotate and adjusting the tension of the conductive cloth. Specifically, during the process of covering the sealing strip with conductive cloth, due to the relatively soft texture of the conductive cloth, it is difficult to maintain a constant tension value during transportation, especially during equipment operation. Sudden acceleration or deceleration, caused by inertia, makes it difficult for the conveyor rollers to quickly adjust the tension value of the conductive cloth, easily leading to uneven coverage of the sealing strip and reduced sealing performance. This technical solution can solve the above problems, and the specific operation is as follows: During the process of covering the sealing strip with conductive cloth, the sealing strip is first coated with glue by the glue tool, then the sealing strip is dried by the air drying fan group, and then it is pulled to the covering tool table 2 by the first pull and wrapped with conductive cloth. The conductive cloth is wound around the unwinding roller 8. The guide wheel group 7 is rotated on the machine tool 1 to guide the conductive cloth to the covering fixture table 2 and wrap the sealing strip. The conductive cloth is pulled by the traction mechanism, so that the unwinding roller 8 rotates with the traction of the conductive cloth. During the rotation of the unwinding roller 8, the tension value of the conductive cloth is detected by the tension detection mechanism. If the tension value increases or decreases, the controller 14 controls the extension end of the electric cylinder 13 to extend or retract. Under the connection of the connecting ring 12, the drive ring 10 slides along the rotating shaft of the unwinding roller 8, and the first sliding pin 11 slides along the drive arc groove 9. Under the guidance of the drive arc groove 9, the unwinding roller 8 rotates in the forward or reverse direction, so that the unwinding roller 8 tightens the excess conductive cloth (when the tension is small) or loosens more conductive cloth (when the tension is large), thereby ensuring the flatness of the conductive cloth on the covering fixture 2, which is beneficial to improving the flatness of the conductive cloth covering the sealing strip, and thus improving the sealing performance of the conductive sealing strip.

[0022] As a further embodiment of the present invention, the tension detection mechanism includes: Two mounting frames 15 are symmetrically and fixedly connected to the machine tool 1. A fixed frame 16 is slidably connected inside the mounting frame 15. A pressure sensor 17 is installed inside the mounting frame 15. The pressure sensor 17 is used to detect the pressure value of the fixed frame 16. Two tension rollers 18 are symmetrically rotated and connected to the fixed frame 16 to stretch the conductive cloth. Specifically, the conductive cloth is spread apart by two tension rollers 18, and the pressure value is detected in real time by the pressure sensor 17. During the rotation of the unwinding roller 8, if the speed at which the unwinding roller 8 releases the conductive cloth is inconsistent with the speed at which the traction mechanism transports the conductive cloth, the force exerted by the conductive cloth on the two tension rollers 18 will change (increase or decrease). Based on the pressure value parameter, the controller 14 controls the extension and retraction of the extension end of the electric cylinder 13 to extend and retract, so that the drive ring 10 slides along the rotating shaft of the unwinding roller 8, causing the unwinding roller 8 to rotate in the forward or reverse direction. This allows the unwinding roller 8 to tighten the excess conductive cloth (when the tension is low) or loosen more conductive cloth (when the tension is high), thereby ensuring the flatness of the conductive cloth on the covering fixture 2, which is beneficial to improving the flatness of the conductive cloth covering the sealing strip, and thus improving the sealing performance of the conductive sealing strip.

[0023] As a further embodiment of the present invention, it also includes a take-up roller 5, which is rotatably connected to the machine tool 1 and is used to collect waste paper on the conductive cloth. The take-up roller 5 and the unwinding roller 8 are connected by a synchronous belt 6 through a pulley. Specifically, by setting a synchronous belt 6, the rotation speed of the take-up roller 5 and the unwinding roller 8 is ensured to be the same, so as to avoid the waste paper being collected in a timely manner or the waste paper on the conductive cloth being torn excessively, which would cause damage to the conductive cloth.

[0024] As a further embodiment of the present invention, the traction mechanism includes two traction roller groups 4, which are symmetrically rotatably connected to the machine tool 1, and the traction roller groups 4 are driven by a drive motor. Specifically, the traction roller group 4 is driven by a drive motor to rotate, so as to press the wrapped conductive sealing strip together and ensure the sealing performance of the conductive sealing strip.

[0025] As a further embodiment of the present invention, it also includes: A folding and turning frame 19 is rotatably connected to the covering tooling table 2. Several first pressure rollers 20 are rotatably connected in an array on the folding and turning frame 19. The first pressure rollers 20 are located above the sealing strip. A turning roller 21 is rotatably connected to the end of the folding and turning frame 19. The turning roller 21 is located below the sealing strip. Servo motor 22 is fixedly connected to the bottom end of the covering fixture 2. The output shaft of servo motor 22 is fixedly connected to the rotating shaft of folding and flipping frame 19. The controller 14 controls servo motor 22 to rotate based on the pressure value detected by pressure sensor 17. When the pressure value increases or decreases, the controller 14 controls servo motor 22 to rotate, driving folding and flipping frame 19 to flip. The sealing strip is moved upward by the agitator roller 21, so that the sealing strip is separated from the conductive cloth. Specifically, by setting up the folding and flipping frame 19, the first pressure roller 20 and the agitator roller 21, when the pressure value detected by the pressure sensor 17 is at a specified threshold, the first pressure roller 20 presses the conductive cloth and the sealing strip together, which helps to ensure the stability of their movement on the wrapping fixture 2 and prepares in advance for the guide module 3 to guide and wrap the conductive cloth and the sealing strip. When the pressure value detected by the pressure sensor 17 is not at the specified threshold, the controller 14 controls the servo motor 22 to rotate, driving the folding and flipping frame 19 to flip. The sealing strip is moved upward by the actuating roller 21, so that the sealing strip leaves the conductive cloth and the two separate. This avoids the sealing strip interfering with the conductive cloth during the adjustment of the conductive cloth tension and helps to restore the originally uneven conductive cloth to a flat state. When the pressure value returns to the threshold, the folding and flipping frame 19 flips and resets, and the first pressure roller 20 presses the conductive cloth and the sealing strip together.

[0026] As a further embodiment of the present invention, it also includes: Two slids 23 are symmetrically arranged on the covering fixture table 2. A U-shaped bracket 24 is slidably connected inside the slids 23. A second pressure roller 25 is symmetrically arranged at the top of the U-shaped bracket 24. A sliding seat 27 is vertically slidably connected to the bottom of the U-shaped bracket 24 and is slidably connected to the bottom of the covering fixture table 2. The guide groove 28 is formed on the inner side wall of the slide groove 23. The guide groove 28 includes a first inclined groove and a straight groove. The side wall of the U-shaped bracket 24 is fixedly connected to a second sliding pin 29, which is slidably connected inside the guide groove 28. The drive mechanism is used to drive the sliding seat 27 to move, so that the U-shaped bracket 24 moves along the track of the guide groove 28; The drive mechanism includes: Two drive plates 30 are symmetrically fixedly connected to the sliding seat 27, and the side wall of the drive plate 30 is provided with a second inclined groove 31. The connecting plate 32 has one end fixedly connected to the rotating shaft of the folding and flipping frame 19, and the other end fixedly connected to the third sliding pin 33, which is slidably connected in the second inclined groove 31. Specifically, during the process of the folding and flipping frame 19 flipping and moving the sealing strip away from the conductive cloth, the connecting plate 32 will flip synchronously with the folding and flipping frame 19, causing the third sliding pin 33 to slide along the second inclined groove 31. Driven by the second inclined groove 31, the sliding seat 27 drives the U-shaped bracket 24 to slide along the sliding groove 23, causing the second sliding pin 29 to slide along the guide groove 28. The second sliding pin 29 first slides along the first inclined groove and then enters the straight groove to move. Driven by the first inclined groove, the U-shaped bracket 24 drives the second pressure roller 25 to move downwards first. After the second pressure roller 25 moves to the top surface of the conductive cloth, the second pressure roller 25 rolls along the edge area of ​​the conductive cloth to further smooth out the uneven areas, further improve the flatness of the conductive cloth, and improve the sealing performance of the conductive sealing strip.

[0027] As a further embodiment of the present invention, the second pressure roller 25 and the U-shaped bracket 24 are connected by a one-way shaft 26 bearing; specifically, during the process of the second pressure roller 25 smoothing the conductive cloth, the one-way shaft 26 bearing prevents the second pressure roller 25 from rotating, thus preventing the conductive cloth from sliding and causing a decrease in flatness. During the process of the second pressure roller 25 resetting, the second pressure roller 25 rotates under the action of the one-way shaft 26 bearing, thus preventing the resetting of the second pressure roller 25 from affecting the flatness of the conductive cloth.

[0028] The present invention also provides a double-sided adhesive bonding device, including a conductive cloth covering device, and further comprising: The adhesive application platform 34 is mounted on the machine tool 1. The side wall of the adhesive application platform 34 is equipped with a suction nozzle 35, which is located below the conductive sealing strip. The suction nozzle 35 is used to absorb dust and impurities on the conductive adhesive strip, ensuring that the double-sided adhesive can be fully adhered to the sealing strip during the application process.

[0029] The working principle of this invention is as follows: During the process of covering the sealing strip with conductive cloth, the sealing strip is first coated with glue by the glue tool, then the sealing strip is dried by the air drying fan group, and then it is pulled to the covering tool table 2 by the first pull and wrapped by the conductive cloth. The conductive cloth is wound around the unwinding roller 8. The guide wheel group 7 is rotated on the machine tool 1 to guide the conductive cloth to the covering fixture table 2 and wrap the sealing strip. The conductive cloth is pulled by the traction mechanism, so that the unwinding roller 8 rotates with the traction of the conductive cloth. During the rotation of the unwinding roller 8, the tension value of the conductive cloth is detected by the tension detection mechanism. If the tension value increases or decreases, the controller 14 controls the extension end of the electric cylinder 13 to extend or retract. Under the connection of the connecting ring 12, the drive ring 10 slides along the rotating shaft of the unwinding roller 8, and the first sliding pin 11 slides along the drive arc groove 9. Under the guidance of the drive arc groove 9, the unwinding roller 8 rotates in the forward or reverse direction, so that the unwinding roller 8 tightens the excess conductive cloth (when the tension is small) or loosens more conductive cloth (when the tension is large), thereby ensuring the flatness of the conductive cloth on the covering fixture 2, which is beneficial to improving the flatness of the conductive cloth covering the sealing strip, and thus improving the sealing performance of the conductive sealing strip.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
