Description

Technical Field

[0001] This utility model relates to the field of electronic wire harness technology, specifically a fixed-length cutting device for electronic wire harness processing. Background Technology

[0002] In the field of electronic equipment manufacturing, electronic wire harnesses are key components, bearing the important responsibility of signal transmission and power supply. Different electronic devices have vastly different requirements for the specifications of electronic wire harnesses, and the length of the wire harness needs to be precisely controlled. Overly long wire harnesses will occupy too much space, increase wiring difficulty and cost, and may also cause damage to internal circuits due to bending. Overly short wire harnesses cannot meet the equipment connection requirements, directly affecting equipment assembly and normal operation. Therefore, a device that can achieve high-precision fixed-length cutting is crucial for ensuring the quality of electronic wire harnesses and improving the production efficiency and stability of electronic equipment.

[0003] However, traditional fixed-length cutting technology for electronic wire harness processing has significant shortcomings. In the measurement stage, simple measuring tools are often used, which are difficult to cope with the complex and diverse requirements of wire harness length. The measurement accuracy is limited, resulting in large deviations in the dimensions of the cut wire harness. During the feeding process, the roller group design lacks scientific design, and the wire harness is prone to deviation and jamming during transportation. This not only reduces the cutting accuracy but also often causes wear on the wire harness surface, affecting its electrical performance. The cutting structure has a slow response speed, and the connection between various actions is not smooth, which seriously restricts the processing efficiency. Moreover, the traditional device has poor stability and frequent failures, which greatly hinders the efficient development of the electronic wire harness processing industry. To address these issues, we propose a fixed-length cutting device for electronic wire harness processing. Utility Model Content

[0011] Compared with the prior art, this utility model provides a fixed-length cutting device for electronic wire harness processing, which has the following beneficial effects:

[0012] 1. This fixed-length cutting device for electronic wire harness processing uses a telescopic ruler at the front end of the cutting frame. Two rulers of different sizes can flexibly extend and retract, accurately measuring the size of the wire harness entering the device according to actual needs. The measurement accuracy is high. Each group of feeding rollers has three equidistant feeding rollers that rotate in coordination and are symmetrically distributed within the cutting frame and cover plate. The lower and upper connecting strips rotate flexibly, and the positioning blocks of the upper and lower baffles are inserted into the positioning grooves. The semi-circular grooves form a ring to fix the wire harness, ensuring smooth and non-deviation-free conveying. This allows the wire harness to accurately reach the preset cutting position. Combined with the high-speed rotation of the rotary cutting blade, high-precision fixed-length cutting is achieved, meeting the stringent dimensional accuracy requirements of electronic wire harness processing.

[0013] 2. This fixed-length cutting device for electronic wire harness processing allows the wire harness to quickly enter from the right end of the cutting frame. The feeding roller assembly starts rapidly, using friction to efficiently drive the wire harness forward. When the preset length is reached, the drive motor quickly drives the threaded rod, which, through the threaded bushing, causes the guide plate to quickly position the cutting assembly. The electric push rod then pushes the rotating cutting blade to quickly complete the cutting action. Afterward, all components quickly reset. The entire process is tightly connected, greatly improving cutting efficiency. At the same time, the stable structural design, such as the storage plate fixing the telescopic ruler, and the upper and lower baffles and connecting strips providing stable support for the feeding roller assembly, ensures that the device remains stable during long-term operation, reduces the occurrence of failures, and guarantees continuous and efficient production.

[0046] Working principle: The wire harness enters the device through the ring formed at the right end of the cutting frame 2. Simultaneously, the telescopic ruler 1 at the front end of the cutting frame 2 begins to function. The telescopic ruler 1 consists of two rulers of different sizes, which work together to achieve telescopic functionality, flexibly adapting to different length measurement needs. The operator can extend the telescopic ruler 1 to a suitable length according to actual needs to accurately measure the size of the wire harness entering the device. The telescopic ruler 1 is inserted and fixed on the storage plate 13 on the left side of the front end of the cutting frame 2, ensuring... Its stability during the measurement process is as follows: After the wire harness enters the cutting frame 2, the feeding roller group 3 inside the cutting frame 2 and at the bottom of the cover plate 4 starts to work. Each feeding roller group 3 consists of three equally spaced feeding rollers, and the three feeding rollers are fixedly connected by a rotating shaft. The positions of the feeding roller group 3 inside the cutting frame 2 and the cover plate 4 correspond to each other and cooperate with each other. They clamp the wire harness through friction and drive it forward. The lower connecting strip 15 and the upper connecting strip 17 respectively engage the feeding roller group 3, and the feeding roller group 3 can rotate flexibly within it. The positioning block at the bottom of plate 16 engages with the positioning groove at the top of the lower baffle 14, ensuring the stability and accuracy of the wire harness during transport and preventing it from shifting or shaking. When the wire harness is transported to the preset length, drive motor 12 starts, and the output shaft of drive motor 12 drives the threaded rod 11 fixedly connected to it to rotate. Since the threaded bushing 10, which is engaged with the threaded rod 11 on the inner side of the left end face of the protective cover 9, slides along the sliding groove at the top of the cover plate 4, thereby moving the entire cutting assembly mounted on the guide plate 7 to the appropriate cutting position. After the cutting assembly is in place, the electric push rod 8 starts to work. The piston shaft of the electric push rod 8 passes through the guide plate 7, pushing drive motor 6 and its connected rotary cutting blade 5 downward. At the same time, drive motor 6 drives the rotary cutting blade 5 to rotate at high speed to cut the wire harness that has reached the designated position. After the cutting is completed, the electric push rod 8 retracts, causing the rotary cutting blade 5 to rise and reset. Drive motor 12 reverses, driving the guide plate 7 back to the initial position, preparing for the next cut.
