Description

Technical Field

[0001] This utility model relates to the field of FFC cable production technology, specifically to an FFC cable aluminum foil cutting and pasting machine. Background Technology

[0002] FFC cable, short for Flexible Flat Cable, is a flat cable with polyester film insulation and polyvinyl chloride (PVC) or fluorinated ethylene propylene (FEP) as sheath. The FFC cable aluminum foil cutting and pasting machine is a piece of equipment specially designed for the production of FFC (Flexible Flat Cable) cables. It can accurately cut and paste aluminum foil onto the FFC cable.

[0003] In the prior art, patent CN211806588U discloses an FFC cable aluminum foil cutting and pasting machine, including a frame, on which are sequentially arranged an FFC cable semi-finished product feeding mechanism, an aluminum foil pasting mechanism, a pressing mechanism, and a traction mechanism. The frame also includes a die-cutting mechanism and an aluminum foil feeding mechanism, both located on one side of the aluminum foil pasting mechanism. The die-cutting mechanism is located between the aluminum foil feeding mechanism and the aluminum foil pasting mechanism. The aluminum foil feeding mechanism is used to place aluminum foil. After being die-cut by the die-cutting mechanism, the aluminum foil passes through the aluminum foil pasting mechanism, which pastes the aluminum foil onto the passing FFC cable semi-finished product. The traction mechanism is used to traction the FFC cable movement. Through the extension and retraction of the telescopic end of the first cylinder, and the cooperation of the first fixed block, the second fixed block, and the slide rod, the pasting component can be stably raised and lowered, thereby realizing the pasting of the die-cut aluminum foil onto the FFC cable semi-finished product.

[0004] These types of FFC cable aluminum foil cutting and pasting machines have some problems. For example, the conveyor rollers are all in fixed positions, which provides limited tension to the aluminum foil. This makes it impossible to meet the tension required by the aluminum foil under different conveying conditions, and it cannot ensure that the aluminum foil maintains a taut state during the conveying process, which affects the bonding effect of the aluminum foil and thus affects the quality of the finished FFC cable.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This embodiment provides a technical solution: an FFC cable aluminum foil cutting and pasting machine, including a cutting and pasting table 1, a cutting and pasting frame 2 fixedly connected to the middle of the upper surface of the cutting and pasting table 1, and a tension adaptive mechanism 3.

[0023] Tension adaptive mechanism 3: It includes an adjusting groove 31, a sliding seat 32, a fixed shaft 33, a connecting rod 34, and a tension roller 38. The adjusting groove 31 is respectively set at the left and right ends of the cutting frame 2. The front and rear ends and the upper end of the adjusting groove 31 are slidably connected to the sliding seat 32. The tension roller 38 is rotatably connected between two horizontally adjacent sliding seats 32. The two upper sliding seats 32 are fixedly connected to symmetrically distributed fixed shafts 33 opposite to their outer surfaces. The lower sliding seats 32 are fixedly connected to a connecting shaft at the end away from the center of the cutting frame 2. The connecting shaft and the vertically adjacent fixed shaft 33 are rotatably connected to the connecting rod 34. The tension adaptive mechanism 3 also includes a telescopic column 35, a spring 36, and a spring 37. Spring 2 37 is fixedly connected between the lower surface of the upper sliding seat 32 and the bottom wall of the horizontally adjacent adjusting groove 31. Telescopic columns 2 are fixedly connected between the lower surface of the upper sliding seat 32 and the bottom wall of the horizontally adjacent adjusting groove 31. Spring 2 37 is movably sleeved on the outer surface of the horizontally adjacent telescopic columns 2. A support plate is fixedly connected to the end of the lower sliding seat 32 away from the center of the cutting frame 2. Telescopic columns 1 35 are fixedly connected between two vertically adjacent support plates. Spring 1 36 is fixedly connected between two vertically adjacent support plates. Spring 1 36 is movably sleeved on the outer surface of the vertically adjacent telescopic columns 1 35. When the aluminum foil passes through the tension roller 38, the aluminum foil exerts a pushing force on the tension roller 38. The force causes both the front and rear tension rollers 38 to move towards the center of the adjusting groove 31. Both tension rollers 38 drive the laterally adjacent sliding seats 32 to move centripetally within their respective adjusting grooves 31. The movement of the sliding seats 32 towards the center of the adjusting groove 31 via the laterally adjacent connecting shafts drives the lower ends of the corresponding connecting rods 34 towards the center of the adjusting groove 31. This causes the upper ends of the connecting rods 34 to push the upper sliding seats 32 upwards via the fixed shaft 33, thereby causing the upper tension roller 38 to move upwards. The upward movement of the upper tension roller 38 causes the two upper sliding seats 32 to move upwards within their respective adjusting grooves 31. The upward movement of the upper sliding seats 32... The telescopic ends of the vertically adjacent telescopic columns 2 extend, and at the same time, the vertically adjacent spring 2 37 is elastically stretched. The sliding seats 32 on both the front and rear sides move towards the center of the adjustment groove 31. Then, through the corresponding support plate, the telescopic ends of the horizontally adjacent telescopic columns 1 35 are compressed, and the horizontally adjacent spring 1 36 is elastically compressed. The elastic force of spring 1 36 and spring 2 37 reacts to the corresponding sliding seats 32. The sliding seats 32 transmit the elastic force to the horizontally adjacent tension rollers 38. The tension rollers 38 provide the required tension for aluminum foil conveying, ensuring the stability of aluminum foil conveying and preventing wrinkles when the aluminum foil is pasted onto the surface of the FFC cable, thus greatly ensuring the production quality of the FFC cable.

[0024] The cutting and pasting frame 2 has a pressing roller 13 rotatably connected to its rear end. Symmetrically distributed guide grooves 9 are provided at the rear end of the cutting and pasting frame 2. Adaptor seats 10 are slidably connected inside each guide groove 9. Adaptor rollers are rotatably connected between two adaptor seats 10. The adaptor rollers and pressing rollers 13 are fitted together. Telescopic columns 11 are fixedly connected between each adaptor seat 10 and each vertically adjacent guide groove 9. Springs 12 are fixedly connected between each adaptor seat 10 and each vertically adjacent guide groove 9. Springs 12 are movably sleeved on the outer surface of horizontally adjacent telescopic columns 11. Aluminum foil and FFC cables pass through the pressing rollers simultaneously. When the adapting roller and the extrusion roller 13 are in contact, the cooperation of the adapting roller and the extrusion roller 13 extrudes and presses the aluminum foil onto the surface of the FFC cable. At the same time, the aluminum foil and the FFC cable push the adapting roller to move upward. The upward movement of the adapting roller causes the two adapting seats 10 to move upward. The adapting seats 10 slide upward inside the corresponding guide grooves 9. The upward movement of the adapting seats 10 causes the telescopic ends of the vertically adjacent telescopic columns 11 to contract. At the same time, the vertically adjacent springs 12 are elastically compressed. The elastic force of the springs 12 reacts to the adapting seats 10, so that the adapting roller and the extrusion roller 13 are tightly fitted together, and the aluminum foil and the FFC cable are stably bonded.

[0025] The cutting frame 2 has a controller 17 on its right side surface. The input end of the controller 17 is electrically connected to an external power source. A support plate 6 is fixedly connected to the front end of the cutting frame 2. Slide openings are provided at both ends of the support plate 6. Guide posts 7 are slidably connected inside the slide openings. The rear ends of the guide posts 7 are fixedly connected to the front end of the cutting blade 5. A fixed roller 4 is fixedly connected to the middle of the cutting frame 2. The central axis of the cutting blade 5 and the fixed roller 4 are located on the same horizontal plane. An electric push rod 8 is provided at the front end of the support plate 6. The telescopic end of the electric push rod 8 is fixedly connected to the front end of the cutting blade 5. The input end of the electric push rod 8 is electrically connected to the output end of the controller 17. The controller 17 enables the electric push rod 8 to run. The telescopic end of the electric push rod 8 extends and pushes the cutting blade 5 backward. Under the support of the fixed roller 4, the aluminum foil is cut. At the same time, the guide posts 7 slide backward inside the corresponding slide openings to provide guidance and limit for the backward movement of the cutting blade 5.

[0026] Among them: the upper end of the cutting and pasting rack 2 is rotatably connected to an aluminum foil roller 15, which stores aluminum foil rolls; both the left and right ends of the cutting and pasting rack 2 are provided with protective covers 16, and the interior of the protective covers 16 is installed in conjunction with the corresponding end of the tension adaptive mechanism 3. The protective covers 16 provide protection for the components of the tension adaptive mechanism 3; both the front and rear ends of the cutting and pasting table 1 are rotatably connected to a conveyor roller 14, which assists in the conveying of the FFC cable.

[0027] The working principle of the FFC ribbon cable aluminum foil cutting and pasting machine provided by this utility model is as follows: During operation, the operator first places the cutting and pasting table 1, the cutting and pasting frame 2, and other mechanisms stably in the horizontal working area. After the placement is stable, the operator uses the external traction mechanism to guide the aluminum foil through the aluminum foil roller 15. The aluminum foil passes sequentially through the lower end of the front tension roller 38, the upper end of the upper tension roller 38, the rear end of the rear tension roller 38, and the front end of the fixed roller 4, and then enters the bonding area. At the same time, the external traction mechanism guides the FFC ribbon cable through the cutting and pasting machine under the conveying action of the conveyor roller 14. When the aluminum foil and the FFC ribbon cable pass between the extrusion roller 13 and the adapting roller, the cooperation of the adapting roller and the extrusion roller 13 achieves the bonding of the aluminum foil to the surface of the FFC ribbon cable. The FFC line pushes the adapting roller upward, which in turn moves the two adapting seats 10 upward. Each adapting seat 10 slides upward within its corresponding guide groove 9. This upward movement of the adapting seats 10 causes the telescopic ends of the vertically adjacent telescopic columns 11 to contract, simultaneously compressing the vertically adjacent springs 12. The elastic force of the springs 12 reacts on the adapting seats 10, ensuring a tight fit between the adapting roller and the extrusion roller 13, achieving stable bonding between the aluminum foil and the FFC cable. Simultaneously, as the aluminum foil passes through the tension roller 38, it exerts a pushing force on the tension roller 38, causing both the front and rear tension rollers 38 to move towards the center of the adjustment groove 31. Both the front and rear tension rollers 38 then drive the horizontally adjacent sliding seats 32 to move centripetally within their corresponding adjustment grooves 31. The movement of the sliding seats 32 on both sides towards the center of the adjusting groove 31 is achieved by the adjacent horizontal connecting shafts driving the lower ends of the corresponding connecting rods 34 towards the center of the adjusting groove 31. This causes the upper ends of the connecting rods 34 to push the upper sliding seats 32 upwards via the fixed shafts 33, thereby causing the upper tension rollers 38 to move upwards. The upward movement of the upper tension rollers 38 causes the two upper sliding seats 32 to move upwards within the corresponding adjusting grooves 31. The upward movement of the upper sliding seats 32 causes the telescopic ends of the vertically adjacent telescopic columns 2 to extend, and simultaneously causes the vertically adjacent springs 2 37 to stretch elastically. The sliding seats 32 on both the front and rear sides move towards the center of the adjusting groove 31, thereby causing the horizontally adjacent telescopic columns 1 35 to move upwards via the corresponding support plates. The telescopic ends of the aluminum foil are compressed, which simultaneously causes the adjacent spring 36 to compress elastically. The elastic forces of spring 36 and spring 37 react on the corresponding sliding seats 32. The sliding seats 32 transmit the received elastic forces to the adjacent tension rollers 38. The tension rollers 38 provide the required tension for aluminum foil conveying, ensuring the stability of aluminum foil conveying and preventing wrinkles when the aluminum foil is applied to the surface of the FFC cable. This greatly ensures the production quality of the FFC cable. When the aluminum foil is conveyed to a certain extent, the external traction mechanism stops traction of the aluminum foil. The controller 17 activates the electric push rod 8. The telescopic end of the electric push rod 8 extends and pushes the cutting blade 5 backward. Under the support of the fixed roller 4, the aluminum foil is cut. At the same time, the guide posts 7 slide backward inside the corresponding sliding opening.It provides guidance and limitation for the backward movement of the cutting blade 5.

[0028] It is worth noting that the controller 17 disclosed in the above embodiments controls the operation of the electric push rod 8 using methods commonly used in the prior art.

[0029] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
