[0040] The movable front seat 4 and the conveying track 3, in this embodiment, the conveying track 3 is arranged at the front section of the frame 1 and extends horizontally. The movable front seat 4 is located at the input end of the conveying track 3, and the movable front seat 4 is provided with a plurality of front through holes 41, and the plurality of front through holes 41 are vertically spaced. The plurality of front through holes 41 correspond to the plurality of bobbin assemblies 11 one by one, so that wires 2 of different specifications can pass through. A vertical cylinder is installed at the bottom of the frame 1, which is used to drive the movable front seat 4 to move up and down, and by driving the movable front seat 4 to rise and fall, different through holes are switched to align with the input end of the conveying track 3, and the wire 2 sent out by the corresponding bobbin assembly 11 enters the conveying track 3 through the front through hole 41, and the conveying track 3 conveys the wire 2, thereby achieving the purpose of automatic line selection.

The two rows of conveying wheels 32 can be driven by two synchronous belt mechanisms respectively, so as to realize the synchronous reverse rotation of the two rows of conveying wheels 32, thereby realizing the function of the conveying track 3 conveying the wires 2 forward.

[0041] Reference Figure 1 and Figure 3 , a movable rear seat 8, in this embodiment, the movable rear seat 8 is vertically slidably connected to the frame 1 and connected to the output end of the conveying track 3. The movable rear seat 8 is installed with a plurality of guide tubes 81, and the apertures of the plurality of guide tubes 81 are respectively adapted to wires 2 of different specifications. The plurality of guide tubes 81 are distributed vertically and extend laterally. A vertical cylinder for driving the movable rear seat 8 to move up and down is also installed at the bottom of the frame 1. By driving the movable rear seat 8 to rise and fall, different guide tubes 81 are switched to align with the output end of the conveying track 3. The wires 2 sent out from the conveying track 3 pass through the guide tubes 81 and then pass out. Since the aperture of the guide tubes 81 is adapted to the wires 2 of the corresponding specifications, the wires 2 have a better limiting effect.

[0042] The cutting assembly 10, in this embodiment, is located at the output end of the conveying track 3 and close to the outlet end of the guide tube 81. The cutting assembly 10 is located at the cutting station of the frame 1, and is used to cut the wire 2 sent out of the guide tube 81.

Before cutting the wire 2, the movable limit slot block is closed with the movable limit slot block under the driving action of the power member to limit the wire 2.

The clamping and reversing component 6 includes a reversing seat 61 vertically rotatably connected to the frame 1 and a reversing jaw 62 installed under the reversing seat 61, wherein the reversing jaw 62 deviates from the rotating axis of the reversing seat 61.

[0045] The clamping and transferring assembly 7, in this embodiment, comprises two transfer jaws 71 arranged side by side in the longitudinal direction. Before cutting, one of the transfer jaws 71 of the clamping and transferring assembly 7 and the reversing jaw 62 under the reversing seat 61 are arranged in sequence behind the cutting assembly 10, and the wire 2 output from the conveying track 3 passes through the cutting assembly 10, one of the transfer jaws 71 of the clamping and transferring assembly 7 and the reversing jaw 62 at the reversing seat 61 in sequence. The clamping and reversing assembly 6 clamps the end of the wire 2 through the reversing jaw 62, and transfers the end of the wire 2 to the other transfer jaw 71 of the clamping and transferring assembly 7 by rotating the reversing seat 61 180º. The two transfer claws 71 of the clamping and transferring assembly 7 clamp and fix the end of the wire 2 and the position where the wire 2 passes through the cutting assembly 10 respectively. After the cutting assembly 10 cuts the wire 2, the clamping and transferring assembly 7 moves the cut wire 2 longitudinally out of the cutting station of the frame 1.

[0046] In this embodiment, the movable front seat 4 is rotatably connected with a plurality of vertically distributed conveying rollers 42, and the plurality of conveying rollers 42 correspond to the plurality of front through holes 41 one by one. The conveying rollers 42 penetrate to the upper side of the corresponding front through holes 41 and abut against the outer wall of the wire 2 in the front through holes 41. The rotating shaft of the conveying roller 42 is arranged longitudinally so that the rotating shaft of the conveying roller 42 and the axis of the front through hole 41 are perpendicular to each other. The frame 1 is equipped with a front driving assembly 5 for driving the conveying roller 42 to rotate. Specifically, the front driving assembly 5 includes a front cylinder 52, a front motor 51 slidably connected to the frame 1, and an electromagnet arranged at the end of the output shaft of the front motor 51. When the front through hole 41 is aligned with the conveying track 3, the axis of the conveying roller 42 corresponding to the front through hole 41 coincides with the axis of the output shaft of the front motor 51, and the front cylinder 52 drives the front motor 51 to move toward the movable front seat 4, and the output shaft of the front motor 51 is fixed to the conveying roller 42 by the electromagnet magnetic attraction. When the movable front seat 4 moves to switch the front end through hole 41, the conveying roller 42 at the output shaft of the front end motor 51 is also switched accordingly, and the output shaft of the front end motor 51 and the conveying roller 42 are magnetically fixed by energizing the electromagnet, so that the corresponding conveying roller 42 can be driven according to the line selection situation. Multiple conveying rollers 42 do not need to be independently equipped with drive components, which is beneficial to reducing the number of drive components, thereby reducing the frequency of maintenance and reducing the probability of equipment failure.

[0047] The implementation principle of the automatic wire selection and cutting device for wire processing in the embodiment of the present application is as follows:

[0048] Multiple wire drum assemblies 11 are respectively wound with wires 2 of different specifications, and the ends of wires 2 of different specifications are respectively in place at different through holes. When selecting wires, the positions of the front through holes 41 are changed by lifting the movable front seat 4, so that the front through holes 41 corresponding to the wires 2 to be processed are aligned with the conveying track 3, and then the front driving assembly 5 drives the conveying roller 42 to rotate, so that the wires 2 to be processed are sent out from the corresponding front through holes 41 and extend into the conveying track 3, and the conveying track 3 continues to convey the wires 2 forward, thereby realizing the function of automatic wire selection.

[0049] Before cutting, one of the transfer jaws 71 of the clamping and transferring assembly 7 and the reversing jaw 62 under the reversing seat 61 are arranged in sequence behind the cutting assembly 10, and the wire 2 output by the conveying track 3 passes through the cutting assembly 10, one of the transfer jaws 71 of the clamping and transferring assembly 7, and the reversing jaw 62 at the reversing seat 61 in sequence. The clamping and reversing assembly 6 clamps the end of the wire 2 through the reversing jaw 62, and transfers the end of the wire 2 to the other transfer jaw 71 of the clamping and transferring assembly 7 by rotating the reversing seat 61 180 degrees. In this embodiment, the reversing jaw 62 and the transfer jaw 71 both adopt the clamping mechanism commonly used in the field of material transfer, and the specific structure is not repeated.

[0050] The two transfer jaws 71 of the clamping and transferring assembly 7 clamp and fix the ends of the wire 2 and the part where the wire 2 passes through the cutting assembly 10 respectively. After the cutting assembly 10 cuts the wire 2, the cut wire 2 is fixed on the clamping and transferring assembly 7 in a folded manner. Finally, the clamping and transferring assembly 7 moves the cut wire 2 longitudinally out of the cutting station of the frame 1. While completing the purpose of automatic cutting, it is also convenient to transfer the cut wire 2 to the next processing station in a way that the two ends are flush, which is convenient for synchronous processing of the two ends of the wire 2 in the subsequent process, which is conducive to improving the processing efficiency of the wire 2. In addition, by transferring the wire end of the wire 2 to another transfer jaw 71 of the clamping and transferring assembly 7 with the clamping and reversing assembly 6, the position of the wire end can be fixed in advance. No matter how long the wire 2 is output by the subsequent conveying track 3, the position of the wire end can be kept fixed, so that the purpose of neatly transferring the cut wire 2 can be achieved.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
