The jig is connected to the frame through a driving device 1; the shearing device is connected to the frame through a driving device 2; 2. The jig is connected to the frame; the shearing device is connected to the frame through a driving device 1 and a driving device 2; 3. The jig is connected to the frame through a driving device 1; the shearing device is connected to the frame through a driving device 2 and a driving device 3.

After the inductor coil after wire trimming is transmitted to the right transmission mechanism 2, the wire pressing cylinder 52 is started, and the piston rod of the wire pressing cylinder 52 is extended, driving the wire pressing plate 53 to move toward the transmission mechanism 2, so that the wire pressing tooth 54 moves toward the wire tail of the inductor coil, squeezes the wire tail toward the center of the inductor coil, and compresses the wire tail after wire trimming.

[0061] like Figure 12-13As shown, the wire-managing mechanism 6 includes a driving component 61, a first wire-managing component 62, and a second wire-managing component 63. The driving component 61 includes a fixed seat 611, a second finger cylinder 612, and a fixed block 613; the fixed seat 611 is an L-shaped structure, and its bottom surface is fixedly connected to the top surface of the pressure plate 34 of the right clamping mechanism 3; the left end of the second finger cylinder 612 is fixedly connected to the right end of the fixed seat 611, and its slide is set downward; the fixed block 613 is horizontally arranged front and back, and is respectively fixedly connected to the two slides of the second finger cylinder 612; the first wire-managing component 62 includes a third connecting member 621, a fourth connecting member 622, a first clamping plate 623, a second clamping plate 624, a first clamping tooth 625, and a second clamping tooth 626; the third connecting member 621 is arranged on the right fixed block 613 on the right end face side; the fourth connecting member 622 is arranged on the left end face side of the left fixed block 613; the first clamping plate 623 is arranged horizontally left and right, and is fixedly connected to the bottom surface of the third connecting member 621; the second clamping plate 624 is arranged horizontally left and right, and is fixedly connected to the bottom surface of the fourth connecting member 622, and the second clamping plate 624 is located behind the first clamping plate 623; the first clamping tooth 625 and the second clamping tooth 626 are L-shaped structures, one end of which is vertically arranged on the bottom surfaces of the first clamping plate 623 and the second clamping plate 624 respectively, and the other end is bent toward the transmission mechanism 2 direction, the first clamping tooth 625 and the second clamping tooth 626 are staggered, and the first clamping tooth 625 is located on the right side of the second clamping tooth 626; the second wire management component 63 is formed by the first wire management component 62 being symmetrically arranged around the center point of the pressure plate 34. After the inductor coil is transmitted to the right transmission mechanism 2 after the wire trimming, the fixture and the inductor coil on the fixture are clamped by the right clamping mechanism 2, and then the second finger cylinder 612 is started, and the two sliders of the second finger cylinder 612 are close to each other, so that the first clamping plate 623 and the second clamping plate 624 move relative to each other, so that the first clamping tooth 625 and the second clamping tooth 626 move relative to each other, and the wire tail of the inductor coil after the wire trimming is corrected. Since the wire tail may bounce off after the wire trimming, the wire tail is corrected by the wire management mechanism 6, so that the wire pressing tooth 54 of the wire pressing mechanism 5 can smoothly press the wire tail.

[0062] The working mode of the utility model is:

[0063] The jig carrying the inductor coil enters the belt conveyor 21 of the left transmission mechanism 2. When the feed sensor senses the jig entering, the feed cylinder 22 is started to extend the feed baffle to the belt conveyor 21, and the belt conveyor 21 stops at the same time. The left clamping mechanism 3 is started, and the clamping cylinder 36 drives the pressing plate 34 to move downward, so that the middle of the bottom surface of the pressing plate 34 is pressed on the jig, and the positioning rod 35 is inserted into the positioning hole of the jig to press the jig and the inductor coil. The motor 415 of the front and rear moving component 41 is started to drive the wire cutting component 42 and the clamping component 43 to move toward the inductor coil, the first finger cylinder 431 is started to make the first clamping member 432 and the second clamping member 433 clamp the wire tail of the inductor coil, and the pneumatic scissors 423 are started to cut off a part of the wire tail of the inductor coil, and then the moving cylinder 441 of the left and right moving component 44 is started to move the wire cutting component 42 to the right to cut off the remaining wire tail of the inductor coil.

[0064] After the wire tail of the inductor coil is trimmed, the discharge cylinder 24 of the left transmission mechanism 2 is started, the discharge block 25 is opened, and the belt conveyor 21 is started at the same time, and the jig is sent into the right transmission mechanism 2. When the feed sensor of the right transmission mechanism 2 senses the entry of the jig, the feed cylinder 22 is started, so that the feed baffle extends to the belt conveyor 21, and the belt conveyor 21 stops at the same time. The left clamping mechanism 3 is started, and the clamping cylinder 36 drives the pressure plate 34 to move downward, so that the middle of the bottom surface of the pressure plate 34 is pressed on the jig, and the positioning rod 35 is inserted into the positioning hole of the jig to press the jig and the inductor coil. At the same time, the second finger cylinder 612 of the wire management mechanism 6 is started, so that the first clamping plate 623 and the second clamping plate 624 move relative to each other, so that the first clamping tooth 625 and the second clamping tooth 626 move relative to each other, and the wire tail of the inductor coil is corrected. The wire pressing cylinder 52 of the wire pressing mechanism 5 is started to drive the wire pressing plate 53 to move toward the wire tail of the inductor coil, squeeze the wire tail toward the center of the inductor coil, and compress the wire tail after cutting.

[0065] Finally, the right discharge cylinder 24 is started, the discharge stopper 25 is opened, and the belt conveyor 21 moves to move the fixture to the next process.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
