[0028] As a preferred embodiment; the conveying mechanism 3 also includes a first movable cylinder 17 and a movable plate 18, the first movable cylinder 17 is fixedly connected to the machine platform 1, the push rod end of the first movable cylinder 17 is fixedly connected to the movable plate 18, and the loading platform 4 is fixedly installed on the top surface of the movable plate 18; it can be understood that the conveying mechanism 3 mainly drives the movable plate 18 and the loading platform 4 to move back and forth through the first movable cylinder 17, so that when working, it can drive the loading platform 4 to move toward the wire pulling mechanism 2, and then the wire pulling head operation; at the same time, the structure of this design is also very compact, the process is stable and reliable, while ensuring smooth operation, it can save equipment space and have good automation connection.

After the circle 5 is fixed; what is mainly fixed is that the position of the inductor 5 cannot be moved, and the inductor 5 is plugged into the connecting shaft (the connecting shaft is arranged on the worktable 4), so when the correction nut touches the end of the wire, the inductor 5 can be rotated. In other words, the fixing mechanism 19 fixes the position of the inductor 5, and the inductor 5 can also rotate on the connecting shaft; in addition, the correction process is: when the worktable 4 is driven to move by the conveying mechanism 3, the end of the wire of the inductor 5 will touch the correction nut, and a vertical correction state will be formed after rotation (a limited position surface is also arranged on the worktable 4, so the end of the wire is resisted by the limited position surface when it rotates), so that the wire head is in a position to be pulled out.

[0031] As a preferred embodiment; the wire drawing machine also includes a feeding mechanism 28, and the feeding mechanism 28 includes an xz two-axis module 29, a pneumatic finger cylinder 30, a first unloading tray 31 and a second unloading tray 32; the xz two-axis module 29 is fixedly connected to the machine table 1, and the moving end of the xz two-axis module 29 is fixedly connected to the pneumatic finger cylinder 30, and the top surface of the machine table 1 and the two sides of the pneumatic finger cylinder 30 are respectively fixedly installed with the first unloading tray 31 and the second unloading tray 32; by providing a feeding machine Structure 28, when the inductor coil 5 completes the wire pulling operation and reaches the feeding mechanism 28, the second movable cylinder 20 on the fixing mechanism 19 will release the inductor coil 5.

When unloading, release the pneumatic finger cylinder 30; the first unloading tray 31 can be a good product conveying channel, and the second unloading tray 32 can be a defective product conveying channel; or vice versa.

The two second material sensors 34 correspond to two thread heads. If the second material sensor 34 does not detect the thread head when passing through the second material sensor 34, it proves that the thread head is not in place (or not pulled out), then it is a defective product and will be sent to the defective product conveying channel by the feeding mechanism 28; otherwise it will be sent to the good product conveying channel.

When the inductor 5 continues to be transported, the thread end will be pulled out by the pressure rod 11. After the thread end is pulled out, the pushing cylinder 8 will immediately release the rocker arm 10, and the rocker arm 10 will also immediately make the pressure rod 11 release the thread end, so that the inductor 5 is separated from the wire pulling device 6 during transportation. At this time, the first moving cylinder 17 drives the wire pulling device 6 to reset; then, when the inductor 5 reaches the feeding mechanism 28, it will be clamped by the pneumatic finger cylinder 30 and transported to the first unloading tray 31 or the second unloading tray 32 for unloading.

[0035] It should be pointed out that the problems existing in the prior art are: the traditional method is to operate by manual wire pulling, which not only consumes a lot of labor, but also leads to a very high defective rate due to the manual wire pulling operation, which greatly affects the production quality of the coil;
