[0004] However, the precision cutting device for electronic connector production of this utility model is a simple mechanical shearing device, which has problems such as unstable cutting length, slow speed and low efficiency. The length control of the cut connector is not precise enough, resulting in a high defect rate of the produced connectors, which cannot meet the production requirements. Therefore, a precision cutting device for electronic connector production is proposed to solve the problems mentioned above. Utility Model Content

It has the advantages of high cutting accuracy and strong practicality, and solves the problems of simple mechanical cutting, unstable cutting length, slow speed, and low efficiency of existing precision cutting devices for electronic connector production. The devices also have insufficient precision in controlling the length of the cut connectors, resulting in a high defect rate of the produced connectors and failing to meet production requirements.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a precision cutting device for the production of electronic connecting wires, comprising a base and a controller fixedly installed outside the base, wherein a wire feeding mechanism is provided on the upper surface of the base, and a cutting mechanism is provided on the upper surface of the base;

[0007] The wire feeding mechanism includes two mounting plates fixedly connected to the top of the base, a wire feeding roller rotatably mounted between the two mounting plates, and a drive motor fixedly mounted to the outside of the left mounting plate.

[0008] The shearing mechanism includes a fixed frame fixedly connected to the top of the base, a servo motor fixedly installed on the upper surface of the fixed frame, a rotating disk fixedly installed on the output shaft of the servo motor, a swing arm hinged to the outside of the rotating disk, a universal joint fixedly connected to the bottom end of the swing arm, and a shearing blade fixedly installed at the bottom end of the universal joint.

The sensing mechanism includes a movable frame disposed on the upper surface of the base, an electric push rod fixedly installed on the upper surface of the movable frame, a connecting seat fixedly installed on the output end of the electric push rod, and a pressure sensor fixedly installed inside the connecting seat.

[0018] Compared with the prior art, this utility model provides a precision cutting device for the production of electronic connecting wires, which has the following advantages:

[0019] 1. This precision cutting device for electronic connector production uses a controller to start a servo motor, which converts the rotational motion of the rotating disk into the linear motion of the shearing blades via a swing arm, enabling rapid cutting of the electronic connector while ensuring cutting accuracy. The controller also starts a drive motor to rotate the wire feeding roller, ensuring stable feeding of the electronic connector and achieving the advantage of high cutting precision.

[0020] 2. This precision cutting device for electronic connector production allows for easy adjustment of the connector height by controlling the extension and retraction of the electric push rod. This, in turn, changes the position of the pressure sensor, thereby precisely controlling the cutting force of the shearing blade on the electronic connector. This prevents damage to the wire or incomplete cutting due to excessive cutting force, ensuring cutting quality. Simultaneously, the pressure sensor ensures stable contact pressure between the shearing blade and the electronic connector during the cutting process, reducing cutting length errors caused by pressure fluctuations and improving cutting accuracy. This meets the high-precision cutting requirements of electronic connector production and offers significant practical advantages. Attached Figure Description
