Description

Technical Field

[0001] This utility model belongs to the field of multifunctional FFC flat wire processing technology, and particularly relates to a quantitative cutting device for multifunctional FFC flat wire processing. Background Technology

[0002] The multi-functional FFC flat cable is a highly flexible and adaptable modern electronic connection cable. It consists of multiple thin conductors arranged in parallel and wrapped in a flexible insulating material, typically made of polymers such as polyester or polyimide, making it both thin and durable. FFC flat cables are designed to meet the needs of data transmission, signal transmission, and power supply within compact spaces, and are widely used in consumer electronics such as laptops, mobile phones, digital cameras, and various electronic devices requiring internal connections.

[0003] Existing quantitative cutting methods lack a device for adaptively adjusting flat wires. The problem with the aforementioned technology is that current multi-functional FFC flat wire processing lacks a clamping and positioning device capable of adaptively adjusting to flat wires of different thicknesses, widths, and materials. Traditional cutting equipment typically uses fixed or single-adjustment structures, which struggle to effectively handle the clamping and positioning needs of diverse wire specifications. This leads to problems such as insecure clamping, positioning deviations, and uneven cutting during actual operation, affecting finished product quality and production efficiency. Furthermore, existing devices often exhibit poor compatibility with wires from different batches and manufacturers due to differences in material hardness, flexibility, and other physical properties, requiring frequent clamp changes or manual adjustments, increasing operational difficulty and labor costs. Utility Model Content

[0008] To improve the applicability of the equipment, preferably, the adjustment device includes a hydraulic pump, a hydraulic cylinder, a fixed platform, a sliding plate, a dual-head motor, a transverse screw, a fixing block, and a cutting blade. The lower surface of the hydraulic pump is fixedly connected to the upper surface of the fixed platform, the upper surface of the hydraulic cylinder is fixedly connected to the lower surface of the fixed platform, the lower surface of the hydraulic cylinder is fixedly connected to the upper surface of the fixed platform, the inner wall of the fixed platform is fixedly connected to the surface of the sliding plate, the output end of the dual-head motor is fixedly connected to the transverse screw, the inner wall of the fixing block is threadedly connected to the surface of the transverse screw, the lower end of the fixing block is fixedly connected to the cutting blade, and the output end of the dual-head motor is fixedly connected to the transverse screw. By driving the screw to rotate through the motor, the cutting width can be automatically adjusted. Fixing blocks are provided at both ends of the transverse screw, and the inner walls of the fixing blocks are threadedly connected to the surface of the transverse screw. When the transverse screw rotates, the two fixing blocks can move synchronously in opposite directions on the transverse screw, thereby adjusting the distance between the two cutting blades.

[0009] To improve the accuracy of clamping and positioning, preferably, the auxiliary device includes a transverse fixing plate, a U-shaped lifting frame, an auxiliary screw, and a servo motor.

[0010] To improve operational stability and consistency, preferably, the inner wall of the fixed frame is provided with a sliding groove, and the bottom of the fixed frame is provided with a base plate. The sliding groove on the inner wall of the fixed frame is used to provide a guide path for the sliding component, so that the relevant actuator can move stably along the set trajectory during the movement. The sliding groove structure can effectively limit the degree of freedom of the sliding component and prevent it from deviating or shaking during operation.

[0011] To improve the continuity of operation, preferably, the left and right ends of the sliding plate are slidably connected to the inner surface of the fixed frame, and the transverse screw is rotatably connected to both ends of the fixed platform. The left and right ends of the sliding plate are slidably connected to the inner surface of the fixed frame, so that the sliding plate can move stably along the inner wall of the fixed frame during the lifting process, thereby effectively improving the guiding accuracy and structural stability during the movement.

[0012] To improve positioning accuracy, preferably, the two ends of the transverse fixing plate are fixedly connected to the inner wall of the fixing frame, and the inner wall of the U-shaped lifting frame is slidably connected to the surface of the cutting plate.

[0015] This invention, through the setting of an adjustment device, an auxiliary device, a fixed platform, a sliding plate, a transverse screw, a transverse fixed plate, a U-shaped lifting frame, and an auxiliary screw, achieves automatic adjustment of the cutting width by setting an adjustment device for quantitative cutting of flat wire, an auxiliary device for fixing the flat wire, and a motor-driven screw rotation. Both ends of the transverse screw are equipped with fixing blocks, the inner walls of which are threadedly connected to the surface of the transverse screw. When the transverse screw rotates, the two fixing blocks can move synchronously in opposite directions on the transverse screw, thereby adjusting the distance between the two cutting blades. The inner wall of the U-shaped lifting frame has a threaded structure matching the auxiliary screw, enabling vertical displacement adjustment through screw transmission. This invention solves the problem of the lack of an adaptive clamping and positioning device in multi-functional FFC flat wire processing. Traditional equipment, due to its fixed or single adjustment structure, cannot meet the diverse wire material requirements, leading to problems such as insecure clamping and positioning deviations, affecting finished product quality and production efficiency. For wires with different physical properties, existing devices have poor adaptability, requiring frequent clamp changes or manual adjustments, increasing operational difficulty and cost.

[0022] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] like Figures 1 to 4As shown in the figure, this utility model provides a multifunctional quantitative cutting device for processing FFC flat wire, including a fixed frame 1, a control box 2, and a cutting plate 3. The control box 2 is located on the front side of the fixed frame 1 and is fixedly connected to the fixed frame 1. The cutting plate 3 is located in the middle of the fixed frame 1, and an adjustment device 4 is located in the middle of the fixed frame 1.

The adjustment device 4 includes a hydraulic pump 401, a hydraulic cylinder 402, a fixed platform 403, a sliding plate 404, a double-head motor 405, a transverse screw 406, a fixing block 407, and a cutting blade 408. The lower surface of the hydraulic pump 401 is fixedly connected to the upper surface of the fixed frame 1, and the hydraulic cylinder... The upper surface of hydraulic cylinder 402 is fixedly connected to the lower surface of fixed frame 1. The lower surface of hydraulic cylinder 402 is fixedly connected to the upper surface of fixed platform 403. The inner wall of fixed platform 403 is fixedly connected to the surface of sliding plate 404. The output end of dual-head motor 405 is fixedly connected to transverse screw 406. The inner wall of fixed block 407 is threadedly connected to the surface of transverse screw 406. The lower end of fixed block 407 is fixedly connected to cutting blade. The output end of dual-head motor 405 is fixedly connected to transverse screw 406. The screw is driven to rotate by the motor, realizing automatic adjustment of cutting width. Fixed blocks 407 are provided at both ends of transverse screw 406. The inner wall of fixed block 407 is threadedly connected to the surface of transverse screw 406. When transverse screw 406 rotates, the two fixed blocks 407 can rotate synchronously on transverse screw 406. The cutting plate 3 moves to adjust the distance between the two cutting blades 408. The auxiliary device 5 includes a horizontal fixing plate 501, a U-shaped lifting frame 502, an auxiliary screw 503, and a servo motor 504. The cutting plate 3 is equipped with a horizontal fixing plate 501 inside, and the cutting plate 3 is fixedly connected to the horizontal fixing plate 501. The surface of the auxiliary screw 503 is threadedly connected to the inner wall of the U-shaped lifting frame 502, and the lower end of the auxiliary screw 503 is fixedly connected to the output end of the servo motor 504. The inner wall of the U-shaped lifting frame 502 is provided with a threaded structure that matches the auxiliary screw 503, which can realize vertical displacement adjustment through screw transmission. The inner wall of the fixing frame 1 is provided with a sliding groove 6, and the bottom of the fixing frame 1 is provided with a base plate 7. The sliding groove 6 on the inner wall of the fixing frame 1 is used to guide the sliding parts. The path ensures that the relevant actuators move stably along a set trajectory during operation. The sliding groove structure 6 effectively restricts the degrees of freedom of the sliding components, preventing deviation or wobbling during operation. The left and right ends of the sliding plate 404 are slidably connected to the inner surface of the fixed frame 1. The transverse screw 406 is rotatably connected to both ends of the fixed platform 403. The sliding plate 404's left and right ends slidingly connected to the inner surface of the fixed frame 1 allows it to move stably along the inner wall of the fixed frame 1 during lifting, effectively improving the guiding accuracy and structural stability during movement. The transverse fixed plate 501 is fixedly connected to the inner wall of the fixed frame 1 at both ends. The inner wall of the U-shaped lifting frame 502 is slidably connected to the surface of the cutting plate 3.The U-shaped lifting frame 502 can move back and forth on the surface of the cutting plate 3, allowing for flexible adjustment of the clamping height according to the thickness of the flat wire to be processed.

The lower end of the servo motor 504 is fixedly connected to the surface of the base plate 7, and the surface of the fixing block 407 is slidably connected to the inner wall of the fixed platform 403. This allows the fixing block 407 to move smoothly along the internal guide direction of the fixed platform 403 under the drive of the transverse screw 406, thereby improving the guiding accuracy and motion stability of the cutting blade 408 during displacement.

[0024] The working principle of this utility model:

[0025] A control box 2 is installed at the front end of the fixed frame 1 for centralized control of the hydraulic pump 401, servo motor 504, and dual-head motor 405 to automate the entire cutting process. Before the equipment is put into use, the operator must place the flat wire to be cut on the cutting plate 3. Then, the servo motor 504 is started, which drives the auxiliary screw 503 to rotate through the transmission mechanism. The external thread of the auxiliary screw 503 engages with the threaded structure on the inner wall of the U-shaped lifting frame 502, thereby realizing the vertical lifting adjustment of the U-shaped lifting frame 502. This adjustment function allows the equipment to precisely adjust its clamping height according to the actual thickness and position of the flat wire, ensuring that the wire is stably fixed in the appropriate position. After the wire is positioned and reliably clamped, the dual-head motor 405 starts working, driving the transverse main screw to rotate. Both ends of the transverse screw 406 are provided with fixing blocks 407, and the fixing blocks 407 have threaded structures that match the transverse screw 406. The structure allows the two fixed blocks 407 to move synchronously along the axis of the transverse screw 406 when it rotates. The lower end of the fixed block 407 is equipped with a cutting blade 408 assembly. By controlling the rotation direction and time of the dual-head motor 405, the distance between the two cutting blades 408 can be precisely adjusted to adapt to different cutting requirements. After the cutting parameters are set, the hydraulic pump 401 starts to work, providing pressurized oil to the hydraulic cylinder 402, pushing the piston rod of the hydraulic cylinder 402 to move downward. The lower end of the hydraulic cylinder 402 is fixedly connected to a sliding plate 404, which moves vertically back and forth along the guide structure inside the fixed platform 403 under the action of gravity and hydraulic pressure. A guide device is provided between the surface of the sliding plate 404 and the inner wall of the fixed platform 403 to ensure that its movement trajectory is stable and accurate, avoiding deviation that affects the cutting quality. Finally, as the sliding plate 404 moves downward, the cutting blade 408 quickly and accurately cuts the positioned flat wire, completing the entire cutting process. This device achieves high efficiency and stability in the cutting process through the organic combination of mechanical transmission, hydraulic drive and electrical control, and is suitable for fixed-length cutting of flat wires of various specifications.

[0026] The specific models and specifications of the hydraulic pump 401, hydraulic cylinder 402, dual-head motor 405, transverse screw 406, auxiliary screw 503, and servo motor 504 proposed in this application need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0027] The wiring connection methods and control methods of the hydraulic pump 401, the dual-head motor 405, and the servo motor 504 proposed in this application are all existing technologies in the field, and therefore will not be described in detail.
