Description

Technical Field

[0001] This utility model relates to the field of wire harness processing equipment technology, and in particular to a core wire stripping and terminal crimping machine with a positioning mechanism. Background Technology

[0002] Wire stripping and crimping machines are key automated equipment in the wire harness processing industry. They can automatically complete the cutting, stripping, and subsequent terminal crimping of wires, greatly improving production efficiency and processing consistency. In the stripping and crimping processes, precise positioning of the wire is the core prerequisite for ensuring processing quality. The wire must be stably fixed in the preset position to ensure that the stripping blade accurately cuts off the specified length of insulation and that the crimping die can accurately crimp onto the wire conductor.

[0003] However, existing wire stripping and crimping machines still have shortcomings in the design of their positioning mechanisms. Many devices use simple clamping mechanisms, such as relying on single-sided clamping or simple pneumatic grippers. During the clamping process, uneven force on the wire can easily cause slight offset or displacement. This slight positioning deviation will be directly transmitted to subsequent processes, resulting in inconsistent stripping lengths, conductor damage, or misaligned or poor crimping of terminals, which seriously affects the electrical connection reliability and yield of the final wire harness product.

[0004] Therefore, this utility model proposes a core wire stripping and terminal cutting machine with a positioning mechanism to overcome the shortcomings of the prior art. Summary of the Invention

[0005] In view of the problems of unstable clamping of the fixing mechanism in the existing wire stripping and terminal crimping machine with positioning mechanism, which easily leads to wire displacement and thus affects the accuracy of subsequent stripping and terminal crimping, this utility model aims to provide a wire stripping and terminal crimping machine with positioning mechanism that has an improved structure and can effectively solve the above problems.

[0006] This utility model provides a core wire stripping and terminal breaking machine with a positioning mechanism, including: an operating machine and a fixing mechanism fixedly connected to the operating machine.

[0007] The fixing mechanism includes a slotted block and a hollow block fixed to the manipulator. An electric push rod is installed inside the hollow block. The output end of the electric push rod is movably connected to a connecting block. The two ends of the connecting block are rotatably connected to the bottom ends of an L-shaped rotating arm. The middle part of the L-shaped rotating arm is rotatably connected to the slotted block through a connecting rod. A clamping plate is fixedly connected to the upper end of the L-shaped rotating arm, and an elastic pad is fixedly connected to the inner wall of the clamping plate.

[0008] Preferably, the wire stripping and terminal breaking machine with positioning mechanism also includes a cleaning mechanism disposed on the operating machine.

[0009] Preferably, the cleaning mechanism includes a housing, and a slide rail is fixedly connected to the bottom wall of the housing.

[0010] Preferably, the cleaning mechanism also includes a motor installed inside the housing, and the output shaft of the motor is connected to a turntable.

[0011] Preferably, the cleaning mechanism also includes a belt that surrounds the turntable.

[0012] Preferably, the cleaning mechanism further includes a slotted plate slidably disposed on the top wall of the housing, a slider fixedly connected to the bottom wall of the slotted plate, and the slider slidably connected to a slide rail.

[0013] Preferably, a vacuum cleaner is fixedly connected to the outer wall of the slotted plate.

[0014] Preferably, the cleaning mechanism further includes a slide bar fixedly connected to the outer wall of the belt, and the slide bar is slidably connected to the slotted plate.

[0015] This utility model has the following beneficial effects: 1. This utility model solves the problem of inaccurate core wire positioning and unstable clamping in the prior art, which leads to low processing accuracy, by setting up a linkage lever-type fixing mechanism consisting of an electric push rod, a connecting block, an L-shaped rotating arm, a connecting rod and a clamping plate.

[0016] 2. This utility model solves the problem that rigid contact of the clamping mechanism is prone to damaging the core wire or cannot be compatible with different wire diameters by fixing elastic pads to the inner walls of the clamping plate. It realizes the use of elastic deformation to enhance the clamping friction, making the clamping more stable, and can adapt to different core wire thicknesses, thus improving the versatility of the equipment.

[0017] 3. This utility model solves the problem that the debris generated during the peeling process is easy to accumulate and contaminate the fixing mechanism or mold, thus affecting the long-term stability and processing accuracy of the equipment, by setting up an automatic cleaning mechanism consisting of a motor, belt, slide bar, slotted plate, slide rail, slider and vacuum cleaner.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] Example: Please refer to Figures 1 to 4 This utility model provides a wire stripping and terminal crimping machine with a positioning mechanism, which aims to solve the problems of inaccurate positioning in existing wire stripping and terminal crimping machines, leading to poor processing and easy residue of debris affecting equipment stability. like Figure 1 and Figure 2 As shown, the wire stripping and terminal crimping machine with a positioning mechanism includes an operating machine 1, a fixing mechanism 2 fixedly connected to the operating machine 1, and a cleaning mechanism 3 disposed on the operating machine 1. Please refer to... Figure 3 The fixing mechanism 2 includes a slotted block 205 and a hollow block 207 fixed to the operating machine 1. An electric push rod 206 is installed inside the hollow block 207. The output end of the electric push rod 206 is movably connected to a connecting block 204. The two ends of the connecting block 204 are rotatably connected to the bottom ends of an L-shaped rotating arm 202. The middle part of the L-shaped rotating arm 202 is rotatably connected to the slotted block 205 through a connecting rod 203. A clamping plate 201 is fixedly connected to the upper end of the L-shaped rotating arm 202. An elastic pad 208 is fixedly connected to the inner wall of the clamping plate 201. When the electric push rod 206 drives the connecting block 204 to move, the clamping plate 201 moves in opposite directions through the lever linkage between the L-shaped rotating arm 202 and the connecting rod 203.

[0022] Please refer to the following carefully. Figure 4The cleaning mechanism 3 includes a housing 307, and a slide rail 308 is fixedly connected to the bottom wall of the housing 307. The cleaning mechanism 3 also includes a slotted plate 302 slidably disposed on the top wall of the housing 307. A slider 309 is fixedly connected to the bottom wall of the slotted plate 302 and is slidably connected to the slide rail 308. A vacuum cleaner 304 is fixedly connected to the outer wall of the slotted plate 302. Through the sliding cooperation between the slider 309 and the slide rail 308, the slotted plate 302 and the vacuum cleaner 304 fixed on the slotted plate 302 are driven to reciprocate along the length direction of the slide rail 308.

[0023] As a preferred embodiment, please refer to Figure 4 The cleaning mechanism 3 also includes a motor 301 installed in the housing 307, and the output shaft of the motor 301 is connected to a turntable 306.

[0024] In a preferred embodiment, the cleaning mechanism 3 also includes a belt 305 surrounding the turntable 306.

[0025] In a preferred embodiment, the cleaning mechanism 3 further includes a slide rod 303 fixedly connected to the outer wall of the belt 305, and the slide rod 303 is slidably connected to the slotted plate 302.

[0026] Working principle: When the core wire needs to be positioned and clamped, the electric push rod 206 installed in the hollow block 207 is activated. The output end of the electric push rod 206 drives the movable connecting block 204 to move downward. The connecting block 204 then pulls the bottom end of the L-shaped rotating arm 202 to move downward synchronously. Since the middle part of the L-shaped rotating arm 202 is rotatably connected to the fixed slotted block 205 through the connecting rod 203, the L-shaped rotating arm 202 rotates under the fulcrum of the connecting rod 203, causing the upper end of the L-shaped rotating arm 202 to drive the fixedly connected clamping plate 201 to move towards each other. The elastic pad 208 of the clamping plate 201 relative to the inner wall finally clamps and fixes the core wire, thus providing stable and high-precision positioning for subsequent stripping and terminal crimping processes. When the equipment generates debris during the peeling operation, the motor 301 installed inside the housing 307 is activated. The motor 301 drives the turntable 306 to rotate. The turntable 306 is circulated by the belt 305 surrounding the turntable 306. The slide rod 303, which is fixedly connected to the outer wall of the belt 305, moves with the belt 305. At the same time, the slide rod 303 is slidably connected to the slotted plate 302, thereby pushing the slotted plate 302. The slider 309, which is fixedly connected to the bottom wall of the slotted plate 302, slides in the slide rail 308 fixed to the bottom wall of the housing 307. This causes the slotted plate 302 and the vacuum cleaner 304, which is fixed to the outer wall of the slotted plate 302, to move back and forth along the path of the slide rail 308, thereby realizing the automatic dust collection and cleaning of debris below the peeling station.
