[0025] The technical solution of the present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0026] Example

[0027] This embodiment provides a wire constant tension follow-up feeding mechanism, referring to Figure 1 and Figure 2 , whose structure includes:

[0028] The frame 10 is made of an aluminum profile fixed in the vertical direction. A slider type electronic ruler 11 is fixedly installed on the frame 10 in the vertical direction. A guide rail slider assembly 12 parallel to the length direction of the slider type electronic ruler 11 is also provided on the frame 10. A counterweight pulley assembly 13 is fixedly connected to the slider of the guide rail slider assembly 12. The counterweight pulley assembly 13 is fixedly connected to the slider of the slider type electronic ruler 11. Limiters are provided at both upper and lower ends of the guide rail of the guide rail slider assembly 12 to prevent the slider type electronic ruler 11 from exceeding the limit range and being damaged.

[0029] Preferably, in a wire constant tension follow-up feeding mechanism of this embodiment, the counterweight pulley assembly 13 includes a mounting plate 131 fixedly connected to the slider of the slider-type electronic ruler 11, and a first movable pulley 132 and a second movable pulley 133 are rotatably connected side by side on the mounting plate 131.

[0030] Preferably, in the electric wire constant tension follow-up feeding mechanism of this embodiment, a counterweight block 134 is fixedly connected to the mounting plate 131 between the first movable pulley 132 and the second movable pulley 133 .

[0031] Preferably, in the electric wire constant tension follow-up feeding mechanism of the present embodiment, a first fixed pulley 16 and a second fixed pulley 17 are rotatably connected to a frame at the upper end of the guide rail slider assembly 12 .

[0032] It also includes a rotatable bobbin 14 and a servo drive motor 15, the power output shaft of the servo drive motor 15 is fixedly connected to the rotating shaft of the bobbin 14, the slider type electronic ruler 11 is connected to the servo drive motor 15, and the slider type electronic ruler 11 controls the rotation amount of the servo drive motor 15 by detecting the position of its slider.

[0033] Before feeding, the bobbin 14 with the cable 18 wound around it is connected to the power output shaft of the servo motor, and the ends of the cable 18 are guided and connected through the second fixed pulley 17, the second movable pulley 133, the first fixed pulley 16 and the first movable pulley 132 and then output upward to the wire processing device.

[0034] The slider type electronic ruler 11, also commonly known as a linear displacement sensor, can accurately measure the position of its slider on the guide rail and output a corresponding electrical signal. When the cable 18 is subjected to tension during the feeding process, the counterweight pulley assembly 13 moves upward along the guide rail slider assembly 12, and at the same time drives the slider of the slider type electronic ruler 11 to move upward.

[0035] The moving position information is captured by the slider type electronic ruler 11 and converted into an electrical signal. The device should also include a control system. The electrical signal is then transmitted to the control system (using a PLC or similar control device). The control system calculates the current tension of the cable 18 based on the position information and compares it with the preset tension value.

[0036] If the actual tension is less than the preset tension, the control system will issue a command to the servo drive motor 15 to increase the rotation amount, thereby increasing the feeding speed of the cable 18 and increasing the tension. On the contrary, if the actual tension is greater than the preset tension, the control system will instruct the servo drive motor 15 to reduce the rotation amount, reduce the feeding speed of the cable 18, and reduce the tension.

[0037] In this way, the constant control of the tension of the cable 18 during the feeding process can be achieved by accurately measuring the position of the counterweight pulley assembly 13 by the slider-type electronic ruler 11 and accurately controlling the servo drive motor 15 by the control system. This control method can ensure that the cable can maintain a stable tension in various processing and use scenarios, thereby improving product quality and production efficiency.

[0038] Based on the above ideal embodiments of this application, the relevant staff can make various changes and modifications without departing from the technical concept of this application through the above description. The technical scope of this application is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
