Description

Technical Field

[0001] This invention relates to the field of conductive sheet production technology, specifically to an automated production device for the continuous preparation of conductive sheets. Background Technology

[0002] With the rapid advancement of electronic information technology, conductive sheets, as an indispensable key material in the manufacturing of electronic components, have become core factors affecting the reliability and market competitiveness of end products due to their performance and production efficiency. Conductive sheets are generally made from conductive particles, thermoplastic matrix materials, and functional binders through a specific composite process. This material has been widely used in many fields due to its unique performance advantages. Whether it is to achieve efficient signal transmission in flexible circuits, effectively block electromagnetic interference in the field of electromagnetic shielding, ensure a precise and sensitive operating experience in touch panels, or help stabilize energy storage and release in new energy batteries, all of these rely on the support of conductive sheets. In the traditional manufacturing process of conductive sheets, the intermittent production mode dominates. This mode requires the use of multiple independent machines to complete a series of processes such as raw material mixing, melt extrusion, and calendering in a predetermined order.

[0003] Existing technologies still have many significant drawbacks. In the material storage stage, the heat emitted from the heating pipes of traditional devices dissipates into the surrounding environment, causing serious energy waste. Furthermore, when the raw materials are mixed, the high coefficient of friction between plastic and conductive particles makes it difficult for the conductive particles to embed smoothly into the plastic particles. This results in a mixing process that is not only energy-intensive but also inefficient. The active ingredients in the binding particles also lack suitable heat activation, failing to uniformly coat the conductive particles and hindering the construction of a stable and effective conductive network. This negatively impacts the conductivity and quality stability of the conductive sheet. In addition, after the mixed material exits the die, the surface often exhibits unevenness due to depressions and material accumulation. During subsequent pressing, these depressions cannot be fully compacted, affecting the conductivity and quality stability of the conductive sheet. Uneven thickness in some areas of the sheet material negatively impacts its electrical performance and mechanical strength. Furthermore, during pressing, uneven pressure distribution in protruding material areas can easily cause excessive compression and deformation of surrounding material, leading to new defects such as cracks. Even after pressing, the final product still exhibits noticeable surface imperfections and extremely poor flatness, failing to meet market demands for high-quality products. In the pressing process, existing roller mechanisms are overly simplistic and lack the flexibility and intelligence to dynamically adjust to surface defects. When minor unevenness remains on the surface of the mixed material after repair, traditional rollers can only apply fixed pressure, unable to apply stronger localized pressure to the repaired area. This results in the final product's surface flatness failing to meet ideal standards, severely affecting the product's appearance and performance. Summary of the Invention

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. In this solution, a three-dimensional heat transfer system consisting of an extrusion pipe, a sealing cover, and a heat transfer plate is constructed by setting up a storage mechanism. This enables precise recovery and gradient utilization of waste heat from production. The heat overflowing from the extrusion pipe is insulated by the sealing cover and then transferred to the storage box inside the storage box via the heat transfer plate. This preheats the bonding particles and plastic particles, softening the plastic particles and reducing the coefficient of friction when mixing them with conductive particles. This makes it easier for the conductive particles to embed, significantly reducing the energy consumption required for mixing and improving production efficiency. At the same time, the bonding particles are activated by heat, resulting in internal active ingredients and surface stickiness. During subsequent mixing, these particles can uniformly coat the conductive particles, forming a stable conductive network and improving the quality of the conductive sheet. 2. In this solution, a pressure roller mechanism is installed, integrating laser detection, particle compensation, airflow shaping, and elastic pressurization. The repair component uses a laser thickness gauge to accurately detect surface defects in the mixed material. When a depression is found, the corresponding storage tilting frame is driven to flip, allowing conductive particles to accurately fill the depression. When a protrusion is found, the acceleration fan is driven to descend, increasing the airflow to flatten the protruding part, making the surface of the mixed material smoother before entering the roller assembly. In the roller assembly, the segmented upper rollers are made of rubber, and each segmented upper roller corresponds to an external sleeve. When the material still has slight unevenness after being processed by the repair component, the electric telescopic rod on the external sleeve extends, driving the force-bearing inner support plate to slightly expand the segmented upper rollers, applying local pressure to the repair area, making the surface smoother, and improving the finished product effect.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Example 1: Please refer to Figures 1 to 8 An automated production apparatus for the continuous preparation of conductive sheets, comprising: The base 1 serves as the fundamental support structure for the entire device. A support frame 2 is mounted on the upper surface of the base 1, and an extrusion pipe 3 is mounted on the upper surface of the support frame 2. The extrusion pipe 3 is one of the core components of the entire device. An energy supply box 35 is also mounted on the upper surface of the support frame 2. The energy supply box 35 is a sealed enclosure structure containing power supply and control circuitry. Multiple heating rings 5 ​​are evenly distributed around the surface of the extrusion pipe 3, providing heat to the extrusion pipe 3 via heating wires. An inner conveying rod 37 is installed inside the extrusion pipe 3. A drive motor 6 for driving the inner conveying rod 37 is located at one end of the extrusion pipe 3. A transfer connection pipe 4 is also located at one end of the extrusion pipe 3. The bottom of the connecting pipe 4 is provided with a discharge mold 10. The transfer connecting pipe 4 serves to connect the extrusion pipe 3 and the discharge mold 10. The upper surface of the base 1 is also provided with a main conveyor belt 11 and a secondary conveyor belt 12. The discharge mold 10 is located above the main conveyor belt 11. When the material is extruded from the discharge mold 10, it will fall directly onto the main conveyor belt 11. An electric lower roller 13 is provided between the main conveyor belt 11 and the secondary conveyor belt 12. A servo motor for driving the electric lower roller 13 is provided on the side surface of the electric lower roller 13. A pressure roller mechanism is also provided on the upper surface of the base 1. The pressure roller mechanism is located above the electric lower roller 13. The upper surface of the extrusion pipe 3 is also provided with a feed opening 36. The feed opening 36 is used to add material into the extrusion pipe 3. A storage mechanism is provided above the feed opening 36. In use, firstly, driven by a user signal, the opening and closing sealing plate 9 above the top cover 8 is flipped open by an electric shaft, exposing the storage box 7 and the heat insulation auxiliary box 24. Then, the operator puts the three raw materials (conductive granules, plastic granules, and adhesive granules) used to make conductive sheets into the storage mechanism for storage. When in use, the storage mechanism is driven to feed the raw materials into the extrusion pipe 3 through the feed opening 36. At this time, the drive motor 6 on the side surface of the extrusion pipe 3 is started, and the inner conveying rod 37 inside the extrusion pipe 3 feeds the three materials... The material is conveyed and mixed, and the power supply box 35 also activates the heating ring 5. The multiple heating rings 5 ​​heat the extrusion pipe 3, thereby raising the temperature of the material inside, so that it can be mixed under the action of the conveying inner rod 37. After the mixed material is conveyed through the extrusion pipe 3 to the inside of the transfer connecting pipe 4, it is discharged through the discharge mold 10 on its bottom surface, and the mixed material is discharged onto the upper surface of the main conveyor belt 11 for conveying. After the mixed material is processed by the pressure roller mechanism, it can form a finished conductive sheet, which can be taken out after being conveyed by the secondary conveyor belt 12, thus completing the production process.

[0018] As a crucial part of the entire production unit, the pressure roller mechanism undertakes the key task of precisely pressing materials and ensuring the surface flatness and thickness uniformity of the product. The pressure roller mechanism includes a roller body assembly and a repair assembly. The roller body assembly includes a control motor 39, which is mounted on the upper surface of the base 1. A threaded output shaft 40 is provided on the output end of the control motor 39. A meshing support rod 50 is engaged with the surface of the threaded output shaft 40. The meshing support rod 50 is a key component that cooperates with the threaded output shaft 40. A connecting inner shaft 38 is provided on one side surface of the meshing support rod 50. The end of the connecting inner shaft 38 facing away from the meshing support rod 50 is... The base 1 has a limiting support rod, and the upper surface of the base 1 is also provided with a limiting rod 47 that cooperates with the limiting support rod. The function of the limiting support rod and the limiting rod 47 is to limit the range of motion of the connecting inner shaft 38. The surface of the connecting inner shaft 38 is provided with multiple segmented upper rollers 14, which are made of rubber. Multiple outer sleeves 58 are sleeved on the surface of the connecting inner shaft 38. Each outer sleeve 58 corresponds to a segmented upper roller 14. Multiple electric telescopic rods 59 are provided on the surface of the outer sleeves 58. The output shaft end of the electric telescopic rod 59 is provided with a force-bearing inner support plate 60, which is in contact with the inner side surface of the segmented upper roller 14. The roller assembly is used to press the mixed material exiting from the discharge mold 10 to form a finished conductive sheet. During use, the electric lower roller 13 is driven by servo motors on its two side surfaces, providing power for the mixed material as it passes over it. After exiting the discharge mold 10, the mixed material is conveyed above the main conveyor belt 11. First, its surface is inspected by a repair assembly. Then, after the repair assembly addresses surface defects (surface depressions and unevenness caused by material accumulation), the mixed material passes through the segmented upper roller 14 and the electric lower roller 13. The gap between them completes the pressing process. If there is an excessively high defect caused by the accumulation of surface material, after the repair component repairs the surface, there may still be slight unevenness on the material surface (such as traces of the repair edge). The outer sleeve 58 at the corresponding position on the surface of the inner shaft 38 is triggered under the drive of the repair component, and multiple electric telescopic rods 59 set on its surface extend outward, driving multiple force-bearing inner support plates 60 to expand outward, so that the segmented upper roller 14 expands slightly. When the mixed material passes through, it can play a local pressure effect, generate stronger pressure on the repaired area, and press the surface flatter, thereby improving the effect of the final product.

[0019] The repair assembly includes four connecting side rods 48. Two connecting side rods 48 are respectively provided on both sides of the connecting inner shaft 38. The connecting side rods 48 possess good rigidity and deformation resistance, enabling them to withstand various external forces during long-term use without damage, ensuring the stable operation of the repair assembly. At each end of the connecting side rods 48 are a ventilation box 49 and a detection box 41. A laser thickness gauge 42 is installed on one side surface of the detection box 41. The laser thickness gauge 42 employs high-precision laser measurement technology, enabling it to measure the thickness of the material surface at extremely high speed and accuracy. A repair air box 43 is installed on one side surface of the laser thickness gauge 42. The repair air box 43 is one of the core functional components of the repair assembly. A top rotating cover 45 is provided on the upper surface of the repair air box 43. An electric shaft is installed at the connection between the top rotating cover 45 and the repair air box 43. Multiple storage tilting frames 51 are installed inside the repair air box 43. These storage tilting frames 51 are used to store the filling powder required for repair. The storage tilting frames 51 are connected to the interior of the repair air box 43. A small electric shaft is installed at the joint. A material feeding opening 52 is provided on the bottom surface of the repair air box 43. An air outlet main pipe 54 is provided on the bottom surface of the repair air box 43. Multiple air outlets 44 are provided on one side surface of the air outlet main pipe 54. These air outlets 44 can evenly spray high-speed airflow onto the material surface, blowing and compacting the repair material to ensure that the repair material can tightly fill the defects on the material surface. An air supply pipe 46 connects the air outlet main pipe 54 and the exhaust box body 49. A conveying pipe 53 is also provided, with openings on the top and bottom surfaces of the conveying pipe 53 to connect the material discharge opening 52 and the air outlet pipe 54. Multiple intermediate frame bodies 55 are provided at the center of the air outlet pipe 54. Inlet and outlet are provided on the upper surface of the intermediate frame body 55. An acceleration fan 56 is provided on the upper surface of the intermediate frame body 55. Multiple small motors 57 are also provided between the repair air box 43 and the air outlet pipe 54. A meshing sub-plate is engaged on the output shaft of the small motor 57. The meshing sub-plate is connected to one side surface of the acceleration fan 56. The repair component is used to treat defects (surface depressions and unevenness caused by material accumulation) on the surface of the mixed material after it exits the discharge mold 10. When the mixed material enters above the main conveyor belt 11, the fan inside the exhaust box 49 is started, and the airflow is conducted to the interior of the exhaust pipe 54 through the air supply pipe 46, and exits from multiple air outlets 44 on the side surface of the exhaust pipe 54 to cool the mixed material. The surface of the mixed material is observed by the laser thickness gauge 42 on the side surface of the detection box 41. When a surface depression occurs, the signal controller inside the detection box 41 drives the small electric shaft on the side surface of the storage tilting frame 51 inside the repair air box 43 corresponding to the depression position, so that it drives the storage tilting frame 51 to tilt. The interior of the multiple storage tilting frames 51 inside the repair air box 43 is pre-filled with conductive particles. When the material is flipped, the conductive particles inside slide out from the inside of the storage flipping frame 51 and exit from the inside of the repair air box 43 through the feeding opening 52. After passing through the conveying pipe 53, they enter the inside of the air outlet pipe 54. With the airflow, the conductive particles are sprayed onto the depressions of the mixed material to fill them. When a protrusion occurs, the signal controller inside the detection box 41 drives the small motor 57 corresponding to the defect location to start. Through the meshing effect of the output shaft of the small motor 57 and the meshing sub-plate, the acceleration fan 56 is driven to descend and enter the inside of the middle frame 55. At this time, the acceleration fan 56 also starts, generating stronger air force, which blows out stronger air force from its corresponding air outlet 44 to flatten the protruding part of the surface of the mixed material. The repair component can make the surface of the mixed material smoother before entering the roller assembly, resulting in a better finished product.

[0020] The storage mechanism includes: a connecting funnel 19, which serves as the connection between the storage mechanism and the subsequent feeding stage. The connecting funnel 19 is located on the upper surface of the feeding opening 36. A sealing cover 27 is provided on the upper surface of the connecting funnel 19. A storage box 7 is located on the upper surface of the sealing cover 27. A top cover 8 is provided on the upper surface of the storage box 7, providing sealed protection for the entire storage box 7. An opening and closing sealing plate 9 is located at the center of the top cover 8. An electric shaft is located at the connection between the opening and closing sealing plate 9 and the top cover 8. Two heat transfer plates 26 are provided on the bottom surface of the storage box 7. The heat transfer plates 26 are made of highly efficient heat-conducting materials, which can quickly transfer external heat to the material inside the storage box 7. In the storage box 7, a mixing disc 15 is provided on one side surface. The mixing disc 15 is a key area for uniform material mixing. An internal motor 16 is provided on the bottom surface of the top cover 8. A stirring support rod 17 is provided at the end of the output shaft of the internal motor 16. The stirring support rod 17 is designed with multiple stirring blades. These stirring blades rotate at high speed under the drive of the internal motor 16, which can perform all-round and multi-level stirring of the materials in the mixing disc 15, so that the various components are fully mixed evenly. A discharge port 18 is opened at the center of the bottom surface of the mixing disc 15. A conveying connection pipe 25 is provided between the bottom surface of the mixing disc 15 and the side surface of the connecting funnel 19. One end of the conveying connection pipe 25 is connected to the discharge port 18, and the other end is connected to the discharge port 18. The end is connected to the interior of the connecting funnel 19. A heat-insulating auxiliary box 24 is provided on the side of the storage box 7 facing away from the mixing disc 15. The heat-insulating auxiliary box 24 is made of heat-insulating material. The heat-insulating auxiliary box 24 is connected to the interior of the storage box 7. Both the heat-insulating auxiliary box 24 and the storage box 7 have a discharge chute 20 inside. Multiple storage boxes 21 are also provided inside the heat-insulating auxiliary box 24 and the storage box 7. One storage box 21 is provided inside the heat-insulating auxiliary box 24, and two storage boxes 21 are provided inside the storage box 7. A discharge opening 23 is provided on one side of each storage box 21. A top conveying cover 22 is provided on the upper surface of each storage box 21. A top feeding port 30 is provided for adding materials into the storage box 21. The upper surface of the top feeding cover 22 is also provided with an observation window 34, which is made of transparent plexiglass. The operator can intuitively understand the remaining amount and usage of materials in the storage box 21 through the observation window 34. A telescopic motor 28 is provided on one side surface of the top feeding cover 22. A lifting sealing plate 29 is provided at the end of the output shaft of the telescopic motor 28. A side motor 31 is also provided on one side surface of the top feeding cover 22. A meshing screw 33 is provided on the output end of the side motor 31. A pushing sliding plate 32 is meshed on the surface of the meshing screw 33. The pushing sliding plate 32 is located on the bottom surface of the top feeding cover 22. Before the processing begins, workers use a feeding device to feed three raw materials (conductive granules, plastic granules, and adhesive granules) into three storage boxes 21 from the top feeding ports 30 above the three top feeding covers 22. The conductive granules are fed into the storage box 21 inside the heat insulation auxiliary box 24, while the plastic and adhesive granules are fed into two storage boxes 21 inside the storage box 7. The plastic granules are fed into the storage box 21 closer to the heat insulation auxiliary box 24, and the adhesive granules are fed into the storage box 21 furthest from the heat insulation auxiliary box 24. When production is required... When the operator sends a start signal via external equipment, the telescopic motors 28 on the side surfaces of the three top feeding covers 22 retract, opening the discharge opening 23 on the side surface of the storage box 21. Then, the side motor 31 is started, utilizing the meshing effect of the engaging screw 33 and the pushing sliding plate 32 to slide the pushing sliding plate 32 inside the storage box 21, pushing the material out of the storage box 21. After exiting the storage box 21, the three materials slide down the discharge chute 20 and into the mixing disc 15. The internal motor 16 inside the mixing disc 15 also starts, driving the stirring support rod. 17 rotates to mix the three types of particles. After mixing, the three types of particles enter the conveying connecting pipe 25 through the discharge port 18, and finally enter the extrusion pipe 3 through the connecting funnel 19 for heating and conveying. When the extrusion pipe 3 is in use, its interior will reach a high temperature due to the heating effect of the heating ring 5. The internal temperature will overflow to the outside through the feed opening 36. After the temperature overflows, the sealing cover 27 can keep the overflowing temperature warm. Subsequently, the temperature is transferred to the interior of the two storage boxes 21 inside the storage box 7 through the two heat transfer plates 26. Because the storage box 21 containing the adhesive particles is located at the lower position... The material is placed in a position where it is subjected to a higher temperature. The overflowing heat preheats the adhesive particles and plastic particles stored inside the storage box 21. After being heated, the surface of the plastic particles softens, reducing the coefficient of friction between them and the conductive particles in the subsequent mixing process. In the subsequent mixing process, the conductive particles can be more easily embedded, reducing the energy consumption required for mixing. After being heated, the adhesive particles can activate their internal active ingredients, making their surface sticky. In the active state, the adhesive particles can uniformly coat the conductive particles, forming a conductive network. By using the overflowing heat to preheat the two types of particles, a better effect can be achieved in the subsequent mixing of materials.

An energy supply box 35 is located on the side surface of the extrusion pipe 3. Multiple heating rings 5 ​​on the energy supply box 35 are fitted onto the surface of the extrusion pipe 3 to heat it. A material conveying inner rod 37 is provided inside the extrusion pipe 3. One end is driven by a drive motor 6, and the other end is connected to the discharge mold 10 through a transfer connecting pipe 4. The discharge mold 10 is located above the main conveyor belt 11. The storage mechanism is responsible for storing raw materials. Storage box 7 and the heat-insulating auxiliary box 24 each have a storage box 21 inside, used to store three types of raw materials for making conductive sheets: conductive granules, plastic granules, and adhesive granules. Before processing, the operator uses an injection device to feed the three raw materials into the corresponding storage box 21 from the top feeding ports 30 above the three top feeding covers 22. During production, the operator sends a start signal, the telescopic motors 28 on the side surfaces of the three top feeding covers 22 retract, opening the discharge openings 23, and the side motors 31 start. The engagement of the meshing screw 33 with the pushing sliding plate 32 drives the pushing mechanism. The sliding plate 32 pushes the material out and into the mixing disc 15 along the feeding slide 20. The internal motor 16 drives the stirring support rod 17 to stir and mix the material. Then, the material enters the extrusion pipe 3 through the feeding port 18, the conveying connecting pipe 25 and the connecting funnel 19. When the extrusion pipe 3 is working, the internal temperature is high. Some of the heat overflows through the feeding opening 36. After the sealing cover 27 keeps it warm, the heat is transferred to the storage box 21 in the storage box 7, which stores plastic particles and binder particles, through two heat transfer plates 26. This preheats the two materials, reduces the friction coefficient between the plastic particles and the conductive particles, and activates the active ingredients of the binder particles, which is beneficial for subsequent mixing. The drive motor 6 starts, the inner conveyor rod 37 conveys and mixes the material, the power supply box 35 starts the heating ring 5 to heat the material, and the mixed material is discharged onto the main conveyor belt 11 through the transfer connecting pipe 4 and the discharge mold 10. The surface defects are first detected by the repair component. If there is a depression, the corresponding storage flipping frame 51 in the repair air box 43 flips, and the conductive particles slide out to fill the depression; if there is a protrusion, the corresponding small motor 57 starts, driving the acceleration fan 56 to descend and generate strong wind to blow the protruding part flat. Next, the mixed material enters the roller assembly. The electric lower roller 13 provides transmission power under the drive of the servo motor. The segmented upper roller 14 on the inner shaft 38 is made of rubber. If there are slight bumps on the surface of the material after repair, the electric telescopic rod 59 on the corresponding position of the outer sleeve 58 extends, driving the force-bearing inner support plate 60 to make the segmented upper roller 14 expand slightly and apply local pressure to make the surface smoother. Finally, the finished conductive sheet is conveyed and taken out by the secondary conveyor belt 12 to complete the production.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
