Technical Field
[0001] This utility model relates to the field of wire harness crimping technology, and in particular to a crimping device for automotive FPC flexible flat wire harnesses. Background Technology
[0002] With the continuous improvement of automotive intelligence and electrification, FPC flexible flat wiring harnesses are increasingly widely used in automotive electronic systems due to their advantages such as small size, flexible wiring, and adaptability to complex spatial layouts. Key components such as in-vehicle displays, sensor networks, and new energy vehicle battery management systems all rely on them to realize signal and power transmission. The bonding quality of FPC flexible flat wiring harnesses and terminals directly affects the stability and safety of automotive electronic systems.
[0003] The shortcomings of existing wire harness terminal crimping devices are: the hydraulic cylinder pushes the lifting plate down to crimp the terminal head on the placement block through the baffle, the overall structure is complicated, and it cannot strip the wire harness ends;
[0004] The existing patent (publication number: CN219535137U) discloses a wire harness terminal crimping device, in which a cylinder pushes the crimping head downward, and the terminal head is crimped by an arc block. By setting a connecting rod, an upper cutting blade and a lower cutting blade, the wire harness end is inserted into a second through groove, and the wire harness end can be stripped so that the terminal head can be fitted onto the outside of the wire harness.
[0005] To address the aforementioned issues, existing patents have provided solutions. However, the peeling structure of the pressing device uses fixed upper and lower cutting blades and is positioned solely by inserting the wire harness into the through slot. This makes it difficult to guarantee the symmetrical precision of peeling the insulation layers on both sides of wire harnesses of different specifications. It is easy for insulation layer residue or conductor scratches to occur on one side, affecting the subsequent pressing quality. Furthermore, the peeling and pressing processes are relatively independent, making it impossible to achieve efficient assembly line operations and failing to meet the needs of large-scale, automated production.
[0006] To address this, a flexible flat wire harness pressing device for automotive FPCs is proposed. Utility Model Content

This device solves the problems of existing pressing devices that use fixed upper and lower cutting blades for the stripping structure and rely solely on wire harness insertion into through slots for positioning. This makes it difficult to ensure the symmetrical accuracy of stripping insulation layers on both sides of wire harnesses of different specifications, which can easily result in insulation layer residue or conductor scratches on one side, affecting the subsequent pressing quality. Furthermore, the stripping and pressing processes are relatively independent, making it impossible to achieve efficient assembly line operations and meet the needs of large-scale, automated production.

[0026] 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.
[0027] Please see Figures 1-5 The present invention provides the following technical solution:
[0028] A flexible flat wire harness pressing device for automotive FPC includes a base 1, a processing frame 2 fixedly connected to the top of the base 1, a stripping component 3 disposed inside the processing frame 2, and a pressing component 4 disposed inside the processing frame 2, the pressing component 4 including a pressing lower mold 401.
[0029] The peeling component 3 includes a rectangular frame 301. A transverse groove 5 is provided on the top of the inner wall of the rectangular frame 301. A bidirectional screw 302 is rotatably connected to the inside of the transverse groove 5 through a bearing. Both sides of the surface of the bidirectional screw 302 are threaded with screw blocks 303, and the screw blocks 303 cooperate with the transverse groove 5. A connecting frame 304 is fixedly connected to the bottom of the screw block 303, and a cutter 305 is fixedly connected to the side of the two connecting frames 304 that are close to each other.
[0030] In this embodiment: by setting the stripping component 3, the rectangular frame 301 is the basic frame of the stripping component 3, which can provide support and protection for the internal structure. The transverse groove 5 can provide installation space and rotation support for the bidirectional screw 302, and at the same time can limit the movement trajectory of the screw block 303. When the bidirectional screw 302 rotates, it will convert the rotational motion into linear motion, driving the screw blocks 303 on both sides to move synchronously. When the screw blocks 303 move, they will drive the corresponding connecting frame 304 and the cutter 305 to move together, so that the two cutters 305 can cut into the insulation layer of the wire harness, realize the precise stripping task, and improve the cutting uniformity.
[0031] Specifically, such as Figure 3 As shown, the lower pressing mold 401 is bolted to the bottom of the inner wall of the processing frame 2, and a U-shaped end 402 is provided inside the lower pressing mold 401.
[0032] Specifically, such as Figure 3 As shown, a hydraulic device 403 is fixedly connected to the top of the processing frame 2, and the telescopic end of the hydraulic device 403 passes through the processing frame 2 and is movably connected to the processing frame 2.
[0033] Specifically, such as Figure 3 As shown, the telescopic end of the hydraulic device 403 is bolted with a pressing head 404, which works in conjunction with the lower pressing mold 401.
[0034] In this embodiment: With the above settings, the lower pressing mold 401 is the base for the pressing operation, which can support the U-shaped end 402 and provide a precise positioning reference, ensuring that the pressing position of the wire harness and the U-shaped end 402 is accurate. The U-shaped end 402 is a transition component for connecting the wire harness conductor to the external circuit. Through pressing, a reliable mechanical connection and electrical conduction can be formed with the wire harness wire. The U-shaped design ensures that the wire harness wire can be smoothly inserted and the deformation after pressing is moderate. The hydraulic device 403 can provide a stable and controllable linear driving force to drive the pressing head 404 to complete the pressing operation. The pressing head 404 can transmit the pressure of the hydraulic device 403 to the U-shaped end 402, causing it to undergo plastic deformation and tightly combine with the wire harness conductor. Furthermore, by bolting the extension end of the hydraulic device 403 to the pressing head 404 and the U-shaped end 402 to the lower pressing mold 401, the pressing mold can be flexibly replaced according to different usage requirements, thereby adapting to diverse pressing needs.
[0035] Specifically, such as Figure 4 , Figure 5 As shown, T-shaped limiting grooves 6 are fixedly connected to both sides of the inner wall of the processing frame 2. T-shaped limiting blocks 7 are slidably connected inside the T-shaped limiting grooves 6, and the two T-shaped limiting blocks 7 are fixedly connected to both sides of the rectangular frame 301 respectively.
[0036] Specifically, such as Figure 1 , Figure 5 As shown, an electric push rod 8 is fixedly connected to the front side of the processing frame 2. The telescopic end of the electric push rod 8 passes through the T-shaped limiting groove 6 and is fixedly connected to the front side of the T-shaped limiting block 7.
[0037] In this embodiment: Through the above settings, the T-shaped limiting groove 6 can limit the movement trajectory of the T-shaped limiting block 7, thereby constraining the movement trajectory of the rectangular frame 301, providing high-precision guidance and lateral support, ensuring the stability and straightness of the stripping assembly 3 during the forward and backward movement. The electric push rod 8 can provide the driving force for the forward and backward movement of the rectangular frame 301. When the electric push rod 8 pushes the rectangular frame 301 forward, the cutter 305 will move forward synchronously. At this time, the manual hand holds the wire harness and keeps it still. The cutter 305 will generate relative displacement with the wire harness, thereby facilitating the cutting of the insulation layer and improving the ease of use.
[0038] Specifically, such as Figure 2 As shown, a guide plate 9 is fixedly connected to the bottom of the inner wall of the processing frame 2, and a collection box 10 is fixedly connected to the rear side of the base 1. The collection box 10 is used in conjunction with the guide plate 9.
[0039] Specifically, such as Figure 4As shown, a micro servo motor 11 is fixedly connected to one end of the bidirectional screw 302. The micro servo motor 11 is fixedly connected inside the transverse groove 5. The micro servo motor 11, the hydraulic device 403, and the electric push rod 8 are all electrically connected to the peripheral controller.
[0040] In this embodiment: With the above settings, the guide plate 9 can guide the insulation layer that falls off during the peeling process, so that it slides down the preset path to the collection box 10. The collection box 10 can collect the insulation layer fragments in a concentrated manner, making it easy to clean regularly, keeping the working environment clean, and reducing the risk of short circuits. The micro servo motor 11 can provide power to the bidirectional screw 302, accurately control the opening and closing distance and movement speed of the cutter 305, and realize the automation and high precision of the peeling process.
[0041] Working principle: First, the FPC wire harness is manually placed in the initial position within the processing frame 2. Then, the micro servo motor 11 is activated via an external controller. The micro servo motor 11 drives the bidirectional screw 302 to rotate, causing the two screw blocks 303 on both sides to move synchronously towards each other, driving the cutter 305. The external controller precisely controls the cutting depth. When the cutter 305 closes to the set distance, the electric push rod 8 is activated. The electric push rod 8 pushes the rectangular frame 301 backward along the T-shaped limiting groove 6. While moving, the cutter 305 remains in the cutting state, which can remove the insulation layer. After stripping is completed, the electric push rod 8 will... The rectangular frame 301 is driven back to its initial position, and the micro servo motor 11 drives the cutter 305 to open to the maximum gap, making it easy to remove the stripped wire harness. Finally, the hydraulic device 403 is activated, which drives the pressing head 404 to move downward. When the bottom of the pressing head 404 contacts the U-shaped end 402, the hydraulic device 403 applies pressure according to the set value, causing the U-shaped end 402 to squeeze the wire harness conductor, thereby forming a tight electrical connection. After pressing is completed, the hydraulic device 403 drives the pressing head 404 to return quickly, so that the pressed wire harness and the U-shaped end 402 can be removed.
[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
