Description

Technical Field

[0001] This utility model relates to the field of connecting wire processing technology, and in particular to a connecting wire cutting device. Background Technology

[0002] As a key component in electronic devices, home appliances, and automotive circuits, connecting wires are widely used in signal transmission and power connection scenarios. Different application scenarios have strict requirements on the length and specifications of connecting wires. For example, the internal wiring of electronic components needs to be accurate to the millimeter level, while automotive wiring harnesses need to be customized to different lengths according to the vehicle body structure. Therefore, the precise cutting and processing of connecting wires is an important part of ensuring product performance.

[0003] Currently, in small-batch or sample production scenarios, the traditional method of cutting connecting lines mostly adopts a manual operation mode of "measuring with a tape measure + cutting with a cutter". Specifically, the operator first marks the length of the connecting line to be cut with a tape measure, and then cuts it along the marked position with a cutter. This method relies on manual operation, has a certain degree of flexibility in small-batch processing, and can complete the basic cutting operation without complex equipment.

[0004] However, this traditional cutting method has significant shortcomings in practical applications. Manual measurement with a measuring tape requires repeated alignment of the scale and marking of the position. Especially in batch processing, the frequent measurement operations are time-consuming and labor-intensive, resulting in low overall production efficiency. To solve this problem, we propose a cutting device for connecting wires. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for cutting connecting wires.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A connecting wire cutting device includes a base and a connecting wire. A support mechanism and a second support frame are respectively installed at both ends of the top of the base. A fixed frame is installed on the side of the support mechanism. The fixed frame has a U-shaped structure and a through groove. A clamping mechanism is installed on the top of the support mechanism. An electric push rod is installed inside the second support frame. The output shaft of the electric push rod passes through the side of the second support frame and is connected to a movable frame. The movable frame is inserted into the fixed frame and is connected to a cutter.

[0008] The support mechanism includes a first support frame fixed on a base. A dual-axis motor and an angle sensor are installed inside the first support frame. A first pulley is installed on the output shaft of one side of the dual-axis motor. The output shaft of the other side of the dual-axis motor passes through the first support frame and is connected to a first roller. A second pulley is installed on the input shaft of the angle sensor. The output shaft of the angle sensor passes through the first support frame and is connected to the second roller. A transmission belt is installed between the first pulley and the second pulley.

[0009] Preferably, the angle sensor is a shaft-type angle sensor, which is used to detect the rotation angle of the second roller.

[0010] Preferably, the diameters of the first roller, the second roller, the first pulley, and the second pulley are exactly the same.

[0011] Preferably, the clamping mechanism is installed on the top of the first support frame, and the fixing frame is installed on the side of the first support frame.

[0012] Preferably, the clamping mechanism includes an adjusting rod rotatably mounted on the top of the first support frame and guide shafts fixed at both ends of the top of the first support frame. A threaded sleeve is threadedly connected to the adjusting rod, and a mounting bracket is fixed to the threaded sleeve. A third roller is rotatably connected to both ends of the side of the mounting bracket, and the mounting bracket is slidably connected to the guide shaft.

[0013] Preferably, the axial direction of both guide shafts is parallel to the axial direction of the adjusting rod.

[0014] Preferably, the connecting line is inserted between the third roller and the first roller on one side, passes through the through groove, and then exits from the third roller and the second roller on the other side.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In the support mechanism of this utility model, the dual-axis motor drives the first and second rollers to rotate synchronously. When the connecting line passes through the gap between the third roller and the first and second rollers, the rotation of the rollers causes the connecting line to move at a constant speed. Since the first and second rollers are connected to the pulley of the angle sensor through the transmission belt, and each roller has the same diameter, the angle sensor can accurately calculate the moving length of the connecting line by detecting the rotation angle of the second roller, thus avoiding the error and time-consuming problems of traditional manual tape measure measurement. At the same time, the clamping mechanism drives the threaded sleeve to move up and down through the adjusting rod, so that the third roller on the mounting bracket clamps the connecting line to prevent it from slipping during movement and ensure the accuracy of length measurement.

[0017] When the length fed back by the angle sensor reaches the preset value, the electric push rod drives the movable frame to move along the through groove of the fixed frame. The cutter at the front end of the movable frame applies pressure to cut the positioned connecting line. This cutting process is automatically executed by the mechanical structure. Compared with manual cutting, it not only cuts more accurately but also avoids the problem of uneven cuts caused by shaking or uneven force during human operation. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-4 A cutting device for a connecting wire includes a base 1 and a connecting wire 5. A support mechanism 2 and a second support frame 7 are respectively installed at the two ends of the top of the base 1. A fixed frame 3 is installed on the side of the support mechanism 2. The fixed frame 3 has a U-shaped structure and a through groove 4 is provided on the fixed frame 3. A pressing mechanism 6 is installed on the top of the support mechanism 2. An electric push rod 8 is installed inside the second support frame 7. The output shaft of the electric push rod 8 passes through the side of the second support frame 7 and is connected to a movable frame 9. The movable frame 9 is inserted into the interior of the fixed frame 3 and is connected to a cutter 10.

[0025] In this embodiment, please refer to Figure 1-4The support mechanism 2 includes a first support frame 21 fixed on the base 1. A dual-axis motor 22 installed inside the first support frame 21 synchronously drives the first pulley 23 and the first roller 24 to rotate via its output shaft. The first pulley 23 drives the second pulley 26 to rotate via a transmission belt 27, causing the output shaft of the angle sensor 25 to drive the second roller 28 to rotate synchronously with the first roller 24. This design, through the power transmission structure of the dual-axis motor 22, ensures that the first roller 24 and the second roller 28 pull the connecting line 5 at the same linear speed, avoiding errors from traditional manual measurement. The angle sensor 25 detects the rotation angle of the second roller 28 in real time. Combined with the first pulley 23 and the second pulley 26, which have the same wheel diameter, the moving length of the connecting line 5 can be accurately calculated, achieving automated length measurement. The fixing frame 3 is installed on the side of the first support frame 21. Its U-shaped structure and through groove 4 provide a precise positioning path for the cutter 10, ensuring the accuracy of subsequent cutting operations.

[0026] First, insert the connecting wire 5 between the third roller 65 and the first roller 24 on one side, pass through the through slot 4, and then pass out from the third roller 65 and the second roller 28 on the other side. Rotate the adjusting rod 61, and the adjusting rod 61 drives the threaded sleeve 63 to slide on the guide shaft 62 through the thread, so that the mounting bracket 64 drives the third roller 65 to move up and down, pressing the connecting wire 5 on the first roller 24 and the second roller 28.

[0027] When the dual-axis motor 22 is started, one output shaft drives the first pulley 23 to rotate. The first pulley 23 drives the second pulley 26 to rotate through the transmission belt 27. The other output shaft drives the first roller 24 to rotate. When the second pulley 26 rotates, the angle sensor 25 detects its rotation angle. At the same time, the second roller 28 rotates synchronously with the first roller 24 under the drive of the output shaft of the angle sensor 25, thereby pulling the connecting line 5 forward.

[0028] When the angle sensor 25 detects that the rotation angle of the second roller 28 has reached the preset value, the angle sensor detects the rotation angle θ of the second roller. According to the wheel diameter r, the moving length of the connecting line L = θ × r / 2π, the electric push rod 8 is started, and its output shaft pushes the movable frame 9 to move along the through groove 4 of the fixed frame 3. The movable frame 9 drives the cutter 10 to apply pressure and cut the connecting line 5 located at the through groove 4. After the cutting is completed, the electric push rod 8 retracts, the dual-axis motor 22 stops running, and one cutting operation is completed.

[0029] In summary, this utility model achieves automated measurement and precise cutting of the connecting wire length through the coordinated design of the support mechanism and the clamping mechanism. The dual-axis motor drives the roller to move the connecting wire, and the angle sensor, combined with the wheel diameter, calculates the length, avoiding errors from manual measurement. The clamping mechanism ensures that the connecting wire does not slip, improving measurement accuracy. The electric push rod drives the cutter to automatically cut the wire, solving the problems of low efficiency and uneven cuts in traditional manual operation, and significantly improving work efficiency.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
