Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wire harness stripping equipment, in particular to a low-voltage wire harness stripping device and a use method thereof. BACKGROUND

[0002] In many industries such as electronics, electrical appliances, and automobiles, wire harnesses are widely used as key components for power and signal transmission. Before use, wire harnesses often need to be stripped according to actual needs to expose the internal wires, facilitating subsequent connection, welding, and other operations. Therefore, efficient, accurate, and stable wire harness stripping processes are crucial to ensuring product quality and production efficiency. Currently, wire harness stripping is mainly achieved through mechanical stripping equipment. With the increasing degree of industrial automation, the market has higher requirements for the automation level, stripping quality, and equipment stability of wire harness stripping equipment. High-automation equipment can reduce manual intervention and improve production efficiency; good stripping quality can ensure the reliability of subsequent wire harness connections; and strong equipment stability can reduce maintenance costs and the risk of production interruptions.

[0003] Some existing wire harness stripping equipment has a low degree of automation and lacks effective linkage mechanisms between operation steps. For example, after the cutting blade completes a cutting action, manual operation is required to move the wire harness for the next cutting. Or, during the cutting process, the component clamping the wire harness cannot automatically adjust the clamping state according to the cutting progress, resulting in an incoherent stripping process that requires frequent manual intervention. This not only increases the labor intensity of the operators but also reduces production efficiency, making it difficult to meet the needs of large-scale, continuous production.

[0004] During the wire harness stripping process, the cutting blade continuously contacts and cuts the outer skin of the wire harness, easily attaching impurities and debris to the surface. If these impurities are not cleaned in time, they will affect the sharpness of the cutting blade, leading to uneven cutting or even damaging the cutting blade. At the same time, a large amount of heat is generated during the cutting process, causing the cutting blade temperature to rise. High temperatures can accelerate the wear of the cutting blade, reduce its service life, and even cause the wire harness outer skin to melt, affecting the stripping quality. However, most existing wire harness stripping equipment does not have effective cutting blade cleaning and cooling devices. Some equipment attempts to use simple blowing or water spraying methods for cleaning and cooling, but the effect is not ideal. Blowing is difficult to completely remove impurities attached to the surface of the cutting blade, and water spraying may cause the equipment to be damp, affecting the normal operation of electrical components, and cannot achieve precise cleaning and uniform cooling of the cutting blade surface.

[0005] The existing wire harness stripping equipment often has the problem of insufficient precision in controlling the movement of the cutting blade, the movement of the wire harness and the action of the clamping component. Due to the insufficient precision of the transmission and cooperation between the components, the cutting depth and length of the cutting blade are difficult to accurately control when cutting the wire harness, and conditions such as over-deep or over-shallow stripping and inconsistent stripping length are prone to occur. In addition, the clamping force of the clamping component on the wire harness is unstable, which may also cause the wire harness to move or deform during cutting, further affecting the stripping quality; the wire harness products produced by such stripping equipment lacking precise control are prone to poor contact, short circuit and other problems during subsequent connection and welding, which seriously affects the performance and reliability of the entire product, increases the product rejection rate and rework rate, and causes great economic losses to the enterprise. Therefore, we provide a low-voltage wire harness stripping device and a use method. SUMMARY

[0023] Further, a method for using the low-voltage wire harness stripping device is also provided, comprising the low-voltage wire harness stripping device according to the claims, and comprising the following steps:

[0024] The movement of the U-shaped plate one drives the L-shaped plate to move the U-shaped plate three, the U-shaped plate three is rotationally connected with the rotating link through the rotating shaft, the other end of the rotating link is rotationally connected with the U-shaped plate two through the rotating shaft, the U-shaped plate two is fixedly installed at the side edge of the clamping block, thereby driving the clamping block to move towards the wire harness main body, the sliding sleeve block slides on the fixed rod one, the spring one is stretched, and the two clamping blocks clamp and fix the wire harness main body;

[0025] During the movement of the clamping block, the arc-shaped limiting block is driven to move through the linkage structure two; after the clamping block clamps and fixes the wire harness main body, the arc-shaped limiting block moves to the opening groove of the cross extending plate, under the action of the spring two, the moving sleeve block slides on the fixed rod two, so that the arc-shaped limiting block is inserted into the opening groove, the clamping block is fixed in position, the clamping block is prevented from loosening, and the wire harness main body is ensured to be stable during the cutting process;

[0026] The starting servo motor drives the threaded rod to rotate, the threaded rod rotates to make the threaded sleeve block slide in the rectangular groove, and the threaded sleeve block drives the U-shaped plate I to move; when the U-shaped plate I moves, the clamping block is driven to move through the linkage structure I; the servo motor continues to drive the threaded rod to rotate, the threaded sleeve block continues to move, drives the U-shaped plate I and the cutting blade to move towards the wire harness body, and the cutting blade contacts the outer skin of the wire harness body; with the continuous movement of the cutting blade, the outer skin of the wire harness body is cut, and at the same time, the cutting blade is rotatably connected with the U-shaped plate I through the rotating shaft, so that the cutting blade can rotate at a certain angle according to the shape of the wire harness body and the cutting resistance during the cutting process, so that the cutting is better completed.

[0027] During the cutting process of the cutting blade, the hollow cylinder is driven to rotate through the linkage structure III; the shaft rotating rod II is driven to rotate by the rotating shaft, the conical gear II at the end of the shaft rotating rod II drives the conical gear I meshing therewith to rotate, the shaft rotating rod I is driven to rotate by the conical gear I, and the hollow cylinder is driven to rotate by the shaft rotating rod I; the brush on the hollow cylinder cleans the cutting blade during the rotating process, and removes impurities attached to the blade during the cutting process; at the same time, the sponge column in the hollow cylinder absorbs the stored water source, and the water source seeps out through the water outlet hole to cool and lubricate the cutting blade, prolong the service life of the cutting blade and improve the cutting quality.

[0028] When the cutting blade moves to the rightmost end, the wire harness body skin cutting is completed, and at the same time, the vertical rod drives the connecting block and the horizontal rod to move synchronously, so that the connecting block hits and presses the switch button on the fixed plate, drives the motor to start, and drives the motor to drive the roller to rotate; when the roller rotates, it contacts the wire harness body and generates friction force, moves the peeled part of the wire harness body outward, realizes automatic moving out of the peeled part, and improves the work efficiency.

[0030] Compared with the prior art, the beneficial effects of the present application are:

[0031] 1、When the cutting blade moves to the far right, the vertical rod contacts the adapter block, triggering the horizontal rod to move synchronously. During this process, the adapter block touches the switch button, causing the guide assembly to operate, while the arc-shaped limiting block moves out of the open slot, and the clamping block no longer clamps the wire harness body due to the cooperation of the fixed rod, spring, and sliding sleeve block. The combination of U-shaped plate II, L-shaped plate, U-shaped plate III, and rotating link makes the horizontal frame rise, allowing the cutting blade to disengage from the wire harness body. The entire process is automated and linked, allowing the wire harness body to automatically move to the right while the guide assembly operates, moving the peeled part out of the way for subsequent peeling work, greatly improving the continuity and efficiency of the peeling work, reducing manual intervention, and reducing the complexity of operation.

[0032] 2、During the cutting blade rolling cutting process, the hollow cylinder is rotated by the transmission of the bevel gear I, shaft rotating rod II, and bevel gear II. On the one hand, the brush on the hollow cylinder cleans the surface of the cutting blade, removing impurities and debris generated during cutting, maintaining the cleanliness of the cutting blade surface, and ensuring cutting accuracy and effectiveness. On the other hand, the centrifugal force generated by the rotation of the hollow cylinder causes the water in the sponge column to be thrown out of the water outlet hole, along the brush to the end and applied to the surface of the cutting blade, which cools the cutting blade, preventing rapid damage due to long-term high-temperature cutting, effectively extending the service life of the cutting blade, reducing equipment maintenance costs, and ensuring the smooth progress of subsequent peeling work.

[0033] 3、Through a series of precise mechanical linkage and transmission structures, precise cooperation of cutting, clamping, moving, cleaning, and cooling actions is achieved. During the movement of the cutting blade, the right movement of the wire harness body, and the cleaning and cooling of the cutting blade, the movement time and position of each component can be accurately controlled to ensure the stability and consistency of each peeling operation. This precise control can effectively prevent uneven peeling, damage to the wire harness, and other problems caused by improper operation or inaccurate component cooperation, thereby ensuring peeling quality and improving product qualification rate, meeting high-quality production and processing requirements.
