Description

Technical Field

[0001] This invention relates to the field of conductive foam die-cutting technology, specifically to a conductive foam positioning die-cutting device. Background Technology

[0002] Currently, conductive foam is a material that combines the elasticity and conductivity of foam for electromagnetic shielding.

[0003] In the manufacturing of communication equipment terminals (including but not limited to smartphones, base station antennas, server chassis, etc.), electromagnetic compatibility (EMC) is a core indicator related to the stability and reliability of equipment performance. To effectively shield internal precision circuits from complex electromagnetic interference from the external environment, conductive foam, as a sealing material with both excellent conductivity and elastic compression properties, is widely used in critical areas such as joints and I / O interfaces of equipment housings. With the evolution of communication technology towards 5G and even 6G, the internal structure of equipment is becoming increasingly compact and highly integrated, and signal frequencies are constantly increasing. This places extremely stringent requirements on the shape complexity, dimensional accuracy, and assembly fit of conductive foam shielding components. Traditional conductive foam processing mainly relies on pre-made steel dies for punching. This process has certain efficiency advantages when dealing with single products with regular shapes and large batches. However, when applied to the current "small batch, multi-variety" and rapidly iterating design of communication equipment terminals, it exposes many inherent defects: poor flexibility and inability to adapt to complex angle cutting; traditional dies have fixed shapes, and one set of dies can only correspond to one cutting contour. When conductive foam with non-perpendicular cut surfaces such as bevels and arcs needs to be processed in different batches or different locations of the same product, multiple sets of special molds must be designed and manufactured, resulting in high production costs and long preparation cycles, which seriously restricts the research and development and market launch speed of new products. Limited positioning accuracy affects final assembly and shielding effectiveness: the internal space of communication equipment is extremely limited, and even a millimeter-level deviation in the installation position of conductive foam may lead to insufficient shielding or difficulties in shell assembly. Traditional die-cutting equipment mostly relies on mechanical limiters for positioning, lacking real-time visual feedback and compensation mechanisms, making it difficult to cope with the slight offsets or deformations that may occur during material transportation, thus affecting the yield and performance consistency of the final product.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0019] Example like Figures 1-7 As shown, a conductive foam positioning and die-cutting device includes a conveying assembly 100, which consists of a conveying base 101 and a conveying belt 102, with the conveying belt 102 mounted on the conveying base 101. The die-cutting device also includes a height adjustment component 200, a fixing component 300, and an adjustable cutting component; The height adjustment component 200 is disposed on the top of the conveying component 100, and the height adjustment component 200 is used to adjust the cutting height; The fixing component 300 is installed at the bottom of the height adjustment component 200, and the fixing component 300 is used to fix the conductive foam. The adjustable cutting components are installed on both sides of the fixed component 300. The adjustable cutting components are used for cutting conductive foam at different angles.

[0020] Specifically, a conductive foam positioning and die-cutting device, its core lies in the coordinated operation of a conveying component 100, a height adjustment component 200, a fixing component 300, and an adjustable cutting component to achieve positioning and multi-angle cutting of conductive foam. The conveying component 100 consists of a conveying base 101 and a conveyor belt 102. The conveyor belt 102 is mounted on the conveying base 101 and is driven by a motor to circulate, conveying the conductive foam to the processing area. The height adjustment component 200 is located at the top of the conveying component 100 and uses a cylinder or screw mechanism to adjust the height of the cutting head to accommodate foam materials of different thicknesses. Its principle is to control the extension and retraction of the cylinder or the rotation of the motor to drive the connecting parts to move up and down, thereby changing the distance between the cutting component and the foam surface. The fixing component 300 is installed at the bottom of the height adjustment component 200 and uses pneumatic or mechanical... A mechanical clamping mechanism secures the conductive foam, preventing displacement during cutting. The drive of the fixing component 300 is based on pneumatic or electric power, applying pressure via a piston or slider to ensure stable foam positioning. Adjustable cutting components are mounted on both sides of the fixing component 300, employing rotatable cutting tools such as heating wires or blades. The cutting angle is changed via motor drive, utilizing a servo motor 407 or stepper motor to control the oscillation of the cutting head. Combined with sensor feedback, precise cutting at different angles is achieved. The entire device's transmission system is coordinated by a PLC controller, ensuring the continuity of the conveying, adjusting, fixing, and cutting processes. The electrical structure, including the motors and sensors, operates based on electromagnetic induction and signal processing. The motor converts electrical energy into mechanical energy to drive the transmission components, while the sensors detect position and angle, sending signals to the controller for real-time adjustments. This design improves cutting efficiency and accuracy, making it suitable for diverse foam processing needs. In this embodiment, the height adjustment component 200 is composed of a gantry frame 201, which is arranged on both sides of the conveying component 100. An adjustment cylinder 203 is installed on the top of the gantry frame 201, and a telescopic shaft 204 is installed at the output end of the adjustment cylinder 203. A connecting disc 205 is fixedly connected to the bottom of the telescopic shaft 204, and a connecting frame 206 is fixedly connected to the bottom of the connecting disc 205.

[0021] Specifically, in the conductive foam positioning and die-cutting device, the height adjustment component 200 consists of a gantry frame 201, which is positioned on both sides of the conveying component 100, forming a stable support structure. An adjusting cylinder 203 is mounted on the top of the gantry frame 201. The output end of the adjusting cylinder 203 is connected to a telescopic shaft 204. When the cylinder is energized, compressed air drives the piston, causing the telescopic shaft 204 to move up and down. A connecting disc 205 is fixedly connected to the bottom of the telescopic shaft 204. The connecting disc 205 is fixed to the connecting frame 206 by bolts or welding, thereby transmitting the linear motion of the cylinder to the connecting frame 206. The connecting frame 206 serves as a load-bearing platform for mounting and fixing the component 300 and the cutting component. The adjusting cylinder 203 operates based on pneumatic transmission, controlling the intake and exhaust of air via a solenoid valve to achieve precise extension and retraction of the telescopic shaft 204. The design of the connecting disc 205 enhances structural stability and prevents deflection. The connecting frame 206 is typically made of lightweight alloy to reduce weight and improve response speed. The entire height adjustment process is programmed and controlled by a PLC or microcontroller. The user can set the desired height, and the cylinder automatically adjusts according to the signal. The transmission path is: the cylinder drives the telescopic shaft 204, the connecting disc 205, and the connecting frame 206 to achieve overall lifting. Electrically, the adjusting cylinder 203 relies on a pneumatic system, including an air compressor, filter, and pressure regulating valve, to ensure stable air pressure. The control circuit manages the cylinder's movement through relays or solid-state switches, combined with position sensor feedback, to achieve closed-loop control, ensuring the accuracy and repeatability of height adjustment. This structure is simple and reliable, suitable for rapid adjustments on high-speed production lines.

[0022] In this embodiment, at least two symmetrically arranged vision sensors 202 are also provided at the bottom of the gantry frame 201. The vision sensors 202 are used for position identification of conductive foam and cutting angle determination.

[0023] Specifically, in the height adjustment assembly 200 of the conductive foam positioning die-cutting device, at least two symmetrically arranged vision sensors 202 are installed at the bottom of the gantry 201. These sensors are used for identifying the position of the conductive foam and determining the cutting angle. The vision sensors 202 are based on optical imaging principles, capturing images of the foam through a camera and transmitting the data to an image processing system. The system analyzes the edges, shape, and position of the foam, calculates the optimal cutting point and angle, and then sends instructions to the height adjustment assembly 200 and the cutting assembly. The working principle of the vision sensors 202 involves CCD or CMOS photosensitive elements, converting light signals into electrical signals, and then identifying feature points through algorithms. In terms of transmission, the sensors are linked with the adjusting cylinder 203 and the cutting motor. When a foam position shift is detected, the sensor triggers a signal, the adjusting cylinder 203 adjusts the height, and the cutting assembly rotates to the corresponding angle. Electrically, the vision sensors 202 are connected to a central controller such as a PLC or industrial computer, transmitting data via Ethernet or serial communication. The control program processes the images in real time to ensure cutting accuracy. Furthermore, the symmetrical arrangement of the sensors eliminates blind spots and improves the reliability of detection. The entire process's transmission chain is as follows: vision sensor 202 collects data, controller processes the data, outputs control signals, and cylinders and motors execute the actions. The integrated vision system design achieves automated positioning, reduces manual intervention, and improves production efficiency and product quality.

[0024] In this embodiment, the fixing component 300 consists of four placement frames 301, which are fixedly connected to the four corners of the connecting frame 206. A transmission frame 302 is fixedly connected to the top of every two adjacent placement frames 301. A lead screw motor 303 is installed at one end of the transmission frame 302. The output end of the lead screw motor 303 is connected to a coaxially arranged bidirectional lead screw 304 through a coupling. A limit slider 305 is sleeved on the bidirectional lead screw 304 through a transmission nut. An electric cylinder 306 is installed at the bottom of the limit slider 305. A sliding shaft 307 is installed at the output end of the electric cylinder 306. An inner groove frame 308 is fixedly connected to the bottom of the sliding shaft 307.

[0025] Specifically, the fixing component 300 in the conductive foam positioning and die-cutting device consists of four placement racks 301, which are fixedly connected to the four corners of the connecting frame 206 to form a rectangular frame. A transmission frame 302 is fixedly connected to the top of every two adjacent placement racks 301, and a lead screw motor 303 is mounted at one end of the transmission frame 302. The output end of the lead screw motor 303 is connected to a coaxially arranged bidirectional lead screw 304 via a coupling. When the motor is energized, the rotational motion is transmitted to the bidirectional lead screw 304 through the coupling. A limiting slider 305 is fitted onto the bidirectional lead screw 304 via a transmission nut, and the limiting slider 305 moves axially as the lead screw rotates. An electric cylinder 306 is mounted at the bottom of the limiting slider 305, and the output end of the electric cylinder 306 is connected to a sliding shaft 307. An inner groove frame 308 is fixedly connected to the bottom of the sliding shaft 307. The electric cylinder 306 operates on the principle of an electric push rod, which drives a gear or screw via a motor to generate linear motion, pushing the sliding shaft 307 up and down. The transmission process is as follows: the lead screw motor 303 rotates, the bidirectional lead screw 304 rotates, the limit slider 305 moves, the electric cylinder 306 adjusts its position, the sliding shaft 307 rises and falls, and the inner groove frame 308 contacts the foam. Electrically, the lead screw motor 303 is typically a stepper motor or servo motor 407, receiving pulse signals to control the rotation angle and direction; the electric cylinder 306 manages the extension and retraction actions through a relay or driver. The entire fixing assembly 300 is coordinated by a controller to achieve the clamping and release of the foam. The design of the limit slider 305 ensures smooth movement and avoids jamming. This structure provides adjustable fixing force to accommodate foams of different sizes, enhancing the flexibility of the device.

[0026] In this embodiment, a plurality of dampers 309 with evenly distributed circular shafts are provided inside the inner groove frame 308, and one end of the plurality of dampers 309 is fixedly connected to a pressure block 310.

[0027] Specifically, within the inner groove frame 308 of the fixed component 300, several dampers 309 are evenly distributed on circular shafts. One end of each damper 309 is fixedly connected to a pressure block 310. Based on hydraulic or pneumatic principles, the dampers 309 provide cushioning and shock absorption. When the pressure block 310 contacts the conductive foam, the damper 309 absorbs the impact force, preventing overpressure damage to the foam. The pressure block 310 is connected to the inner groove frame 308 via the dampers 309, forming a floating clamping mechanism. In terms of working principle, the damper 309 is filled with fluid or elastic material, generating resistance under pressure and evenly distributing the pressure. During transmission, when the electric cylinder 306 pushes the sliding shaft 307 and presses down the inner groove frame 308, the pressure block 310 first contacts the foam, compressing the dampers 309 and adapting to the unevenness of the foam surface to ensure uniform fixation. Electrically, the damper 309 is a passive component, not directly powered, but linked to the electric cylinder 306, indirectly managing the clamping force through the cylinder's control signal. The clamping block 310 is typically made of soft material to avoid scratching the foam. The entire fixing action's transmission chain is: electric cylinder 306 drives, sliding shaft 307 moves, inner groove frame 308 descends, damper 309 compresses, and clamping block 310 applies pressure. This design improves the stability and adaptability of the fixing process, making it particularly suitable for easily deformable foam materials and reducing the scrap rate in production.

[0028] In this embodiment, the adjustable cutting assembly 400 includes an arc-shaped guide rail 401, which is fixedly connected to two placement frames 301 on the same side. A guide frame 403 is slidably sleeved on the arc-shaped guide rail 401, and a heating cutting wire 410 is installed on both guide frames 403.

[0029] Specifically, the adjustable cutting assembly includes an arc-shaped guide rail 401, which is fixedly connected to two placement frames 301 on the same side, forming an arc-shaped track. A guide frame 403 is slidably fitted onto the arc-shaped guide rail 401, and a heating cutting wire 410 is mounted on both guide frames 403. The heating cutting wire 410 generates high temperature through resistance heating, which is used to melt and cut conductive foam. The guide frames 403 slide on the arc-shaped guide rail 401, changing the angle of the cutting wire to achieve multi-directional cutting. In terms of transmission, the movement of the guide frames 403 is driven by a motor, moving along the guide rail via gears or belts. The power supply of the heating cutting wire 410 is managed by a controller, which regulates the current to control the temperature, ensuring smooth cutting and clean edges. Electrically, the heating wire is based on the Joule effect; current passing through the resistance wire generates heat. A temperature sensor may be integrated into the heating wire, providing feedback to maintain a constant temperature. The guide frames 403 may contain insulating material to prevent short circuits. The entire cutting process transmission chain is as follows: the motor drives the guide frame 403 to slide, the heated cutting wire 410 is positioned, electricity is applied for heating, and the cutting is completed upon contact with the foam. This adjustable design allows for customized cutting angles, improving the versatility and precision of the device, and making it suitable for processing foams with complex shapes.

[0030] In this embodiment, an arc-shaped rack 402 is fixedly connected to one side of the arc-shaped guide rail 401, a drive motor 404 is installed on the top of the guide frame 403, a drive shaft 405 is installed at the output end of the drive motor 404, and a meshing gear 406 is fixedly sleeved on the outer circumferential surface of the drive shaft 405, and the meshing gear 406 meshes with the arc-shaped rack 402.

[0031] Specifically, in the adjustable cutting assembly, an arc-shaped rack 402 is fixedly connected to one side of the arc-shaped guide rail 401, and a drive motor 404 is mounted on the top of the guide frame 403. A drive shaft 405 is mounted on the output end of the drive motor 404, and a meshing gear 406 is fixedly sleeved on the outer circumference of the drive shaft 405. The meshing gear 406 meshes with the arc-shaped rack 402. When the drive motor 404 is energized, the rotational motion is transmitted to the meshing gear 406 through the drive shaft 405. The meshing of the gear and rack converts the rotational motion into linear sliding of the guide frame 403 along an arc-shaped path. The working principle is based on gear transmission; the teeth of the meshing gear 406 engage with the tooth grooves of the arc-shaped rack 402 to ensure smooth movement. The drive motor 404 is typically a servo motor 407 or a stepper motor, receiving control signals to precisely control the rotation angle and speed, thereby adjusting the cutting position. In terms of electrical structure, the motor is connected to the PLC via a driver, and the cutting trajectory is programmed. A position sensor may be used to provide feedback on the actual position of the guide frame 403, achieving closed-loop control. The transmission path is as follows: the drive motor 404 rotates, the drive shaft 405 rotates, the meshing gear 406 rolls along the rack, the guide frame 403 slides, and the heated cutting wire 410 adjusts its angle. This design provides high-precision angle control, is suitable for foam processing requiring complex cutting patterns, and enhances the level of automation.

[0032] In this embodiment, a servo motor 407 is installed at the bottom of the guide frame 403, and a rotating shaft 408 is installed at the output end of the servo motor 407. A take-up reel 409 is fixedly sleeved on the rotating shaft 408. The heating and cutting wire 410 is fixedly fixed on the two take-up reels 409. Two symmetrically arranged straight shafts 411 are rotatably installed inside the guide frame 403. Guide wheels 412 are fixedly sleeved on the outer circumferential surface of the straight shafts 411. The heating and cutting wire 410 passes through the four guide wheels 412.

[0033] Specifically, a servo motor 407 is mounted at the bottom of the guide frame 403. A rotating shaft 408 is mounted at the output end of the servo motor 407, and a take-up reel 409 is fixedly sleeved on the rotating shaft 408. The heated cutting wire 410 is simultaneously fixed on two take-up reels 409. Two symmetrically arranged straight shafts 411 are rotatably mounted inside the guide frame 403. Guide wheels 412 are fixedly sleeved on the outer circumference of the straight shafts 411, and the heated cutting wire 410 passes through the four guide wheels 412. The working principle of the servo motor 407 is based on precise position control. The rotation angle is fed back by an encoder, driving the rotating shaft 408 to rotate, thereby winding or releasing the heated cutting wire 410 on the take-up reels 409. The guide wheels 412 reduce friction and ensure smooth movement of the cutting wire. The transmission process is as follows: the servo motor 407 rotates, the rotating shaft 408 drives the take-up reels 409 to rotate, the heated cutting wire 410 is tightened or loosened, and guided and positioned by the guide wheels 412. In terms of electrical principle, the servo motor 407 receives pulse signals to control the direction and speed of the take-up reel 409, maintaining constant tension in the cutting wire. The power supply to the heated cutting wire 410 is independently controlled, with the energizing time adjusted via a relay. The entire system coordinates the servo motor 407 and the heating circuit through a controller, achieving precise movement and heating of the cutting wire. This design allows for rapid adjustment of the cutting wire length and position to accommodate different sizes of foam, improving production efficiency and cutting quality.

[0034] Working Principle: The entire die-cutting process begins with the conveyor assembly 100. A motor-driven conveyor belt 102 continuously rotates on the conveyor base 101, smoothly transporting the conductive foam to be processed to the processing station. Once the foam reaches the predetermined position, the device enters the precision positioning and cutting stage. First, the vision sensors 202, symmetrically arranged at the bottom of the gantry 201, are activated. Their internal CCD or CMOS photosensitive elements capture real-time images of the foam, converting optical signals into electrical signals and transmitting them to the central PLC controller. The image processing system quickly analyzes the edge contour and position coordinates of the foam, calculating the optimal cutting point and required angle, providing data instructions for subsequent actions.

[0035] Next, the height adjustment component 200 begins to operate. The PLC sends a signal to the adjustment cylinder 203, and the solenoid valve controls the compressed air to enter the cylinder, pushing the piston and the connected telescopic shaft 204 to move vertically. The telescopic shaft 204 drives the entire connecting frame 206 to rise and fall via the connecting disc 205 at the bottom, thereby precisely adjusting the height of the fixing component 300 and the cutting component mounted on the connecting frame 206 to accommodate foam materials of different thicknesses.

[0036] After positioning, the fixing component 300 performs a clamping action. Upon receiving the command, the lead screw motor 303 rotates, driving the bidirectional lead screw 304 to rotate via a coupling. The limiting sliders 305, sleeved on the lead screw, move in opposite directions to adjust to a position suitable for the foam width. Subsequently, the electric cylinder 306 at the bottom of the limiting slider 305 is activated, pushing the sliding shaft 307 and the inner groove frame 308 downwards. The dampers 309, evenly distributed on the inner cylindrical shafts of the inner groove frame 308, play a crucial role in this process. Their internal hydraulic or pneumatic mechanisms effectively absorb impact energy, allowing the pressure block 310 connected to the end of the damper 309 to adaptively press the foam surface with a balanced force, preventing displacement and avoiding product deformation or damage caused by overpressure.

[0037] Finally, the adjustable cutting component performs the core cutting operation. To achieve multi-angle cutting, the drive motor 404 starts, and its output shaft drives the meshing gear 406 to roll along the arc-shaped rack 402 fixed to the side of the arc-shaped guide rail 401, thereby causing the entire guide frame 403 to slide along the arc-shaped trajectory, adjusting the heated cutting wire 410 to the optimal cutting angle set by the vision system. At the same time, to ensure that the cutting wire is always taut, the servo motor 407 at the bottom of the guide frame 403 works, precisely controlling the take-up and untake-up actions of the take-up reel 409 through the rotating shaft 408. The heated cutting wire 410 is tensioned and precisely positioned as it passes through the four guide wheels 412. At the moment the cutting wire is energized, based on the Joule effect, the current passes through the resistance wire to generate high temperature, instantly melting the foam material. Under the unified coordination of the PLC controller, all components work together to complete a precise, efficient, and smooth-edge cutting operation. The entire system achieves fully automated and efficient operation from conveying, identification, positioning, and pressing to multi-angle cutting through the organic combination of electric, pneumatic, and mechanical transmission.
