Detailed implementation manners

[0029] The present invention will be further described below with reference to the accompanying drawings:

[0030] As Figure 1 、 2 As shown in FIGS. 1, 2, and 3, this embodiment includes a feeding device, a straightening device 3, a wire arranging tension control device 4, a winding mechanism 5, and a wire winding mechanism 6 arranged in sequence according to the process. Specifically, the feeding device is arranged on the frame body 8, and the straightening device 3, the wire arranging tension control device 4, the winding mechanism 5, and the wire winding mechanism 6 are arranged on the workbench 7.

[0031] The feeding device includes a wire unwinding assembly 1 and a material storage assembly 2. The wire unwinding assembly 1 includes a spool 11 with a cable 9 wound thereon, and a second driving motor 12 for driving the spool 11 to rotate. The second driving motor 12 is used to rotate the spool 11 so that the cable 9 on the spool 11 is actively released and conveyed to the material storage assembly 2. The material storage assembly 2 includes a vertically placed support frame 21. At the left and right ends of the support frame 21, a first wire guide pulley 22 and a second wire guide pulley 23 are provided. In the middle of the support frame 21, a fixed pulley set 24 and a movable pulley set 25 are arranged up and down. A heavy object 252 is also installed on the movable pulley set 25. Both the fixed pulley set 24 and the movable pulley set 25 include a housing and four pulleys 252 that are arranged inside and can rotate independently; the fixed pulley set 24 is located at the top of the support frame 21, and the movable pulley set 25 is arranged below the fixed pulley set 24. Specifically, the cable 9 on the spool 11 first passes through the first wire guide pulley 22, then bypasses the pulleys 252 of the movable pulley set 25 and is connected, then goes up and bypasses the pulleys 252 of the fixed pulley set 24, then goes down and bypasses the pulleys 252 of the movable pulley set 25 again, and then bypasses the second wire guide pulley 23 and is connected to the next process. Through the above material storage assembly 2, when the overall device stops working and conveying the cable 9, under the action of gravity, the counterweight pulls the movable pulley set 25 downward, the distance between the fixed pulley set 24 and the movable pulley set 25 gradually becomes longer, and the cable 9 wound on it also extends accordingly. Workers can remove the wire coil, reinstall the winding wheel, and then start the overall device to wind the wire. At this time, under the operation of the driving motors of the subsequent processes, the tension of the cable 9 is greater than the tension of the counterweight, and the distance between the fixed pulley set 24 and the movable pulley set 25 gradually becomes shorter, thus forming a situation where the winding machine pauses and performs wire replacement processing.

[0032] The straightening device 3 includes straightening rollers 31 arranged in a staggered manner up and down, and the wire sequentially passes through each straightening roller 31 up and down. Specifically, the cable 9 conveyed from the feeding device enters the next process after being straightened by the straightening device 3.

The tension control system consists of a pressure sensor 42, a magnetic powder brake 41, and a tension controller (placed on the front cabinet door of the operation console) to form a closed-loop control. When the winding reaches the set value, press the shearing button on the touch screen. The pneumatic wire clamping device 44 first clamps the wire and then cuts the wire. Specifically, the cable 9 conveyed from the straightening device 3 first passes through the magnetic powder brake 41, the length measuring encoder 43, the pneumatic wire clamping device 44, the pneumatic cutting device 45, and the wire arranging wheel 46 in sequence and then enters the next process.
