The inductor production line can complete each step of making the inductor in sequence with high efficiency, and the devices and mechanisms required for each step of the inductor production are concentrated on the machine 100, so that the structure of the inductor production line is relatively compact and occupies relatively less space.

[0027] Reference Figure 4 In some embodiments, the terminal punching device 500 includes a reel 510, a slitting mechanism 520, a first rotary clamping mechanism 530 and a terminal punching mechanism 540.

[0032] The machine 100 is provided with a waste collecting trough 525 , which is disposed below the cutting board 521 . The waste collecting trough 525 is used to collect damaged terminals and auxiliary materials punched out from the terminal strip by the punching knife 523 .

[0033] A conveying path 121, a first rotating clamping mechanism 530 and a slitting mechanism 520 are arranged in sequence, and the rotating axis of the first rotating cylinder 532 is parallel to the conveying direction of a conveying path 121, so that when the first rotating cylinder 532 drives the first horizontal linear driving mechanism 533 and the terminal clamp 531 to rotate, the terminal clamp 531 can face the slitting mechanism 520 and upward.

[0034] The front end of the unwinding terminal strip 510 passes between the driving wheel and the driven wheel, and the rotary drive mechanism drives the driving wheel to rotate, thereby driving the terminal strip to be transported to the slide groove 521a of the chopping board 521. The limiting protrusion 521c can be close to the limiting groove on the terminal strip to ensure that the terminal strip moves along the length direction of the slide groove 521a. When the auxiliary material of the terminal strip moves to face the through hole 521b, the terminal strip stops moving, and the first rotating clamping mechanism 530 drives the first horizontal linear driving mechanism 533 and the terminal clamping claw 531 to rotate, so that the terminal clamping claw 531 faces the opening of the slide slot 521a, and the first horizontal linear driving mechanism 533 drives the terminal clamping claw 531 to extend into the slide slot 521a, and the terminal clamping claw 531 clamps the terminal at the front end of the terminal strip, and the first lifting driving mechanism 522 drives the punching knife 523 to pass through the through hole 521b from top to bottom, and the punching knife 523 cuts off the auxiliary material, and the terminal at the front end of the terminal strip is separated from the terminal strip and is on the terminal clamping claw 531, and then the first horizontal linear driving mechanism 533 drives the terminal clamping claw 531 to move away from and exit the slide slot 521a, and the first rotating clamping mechanism 530 drives the first horizontal linear driving mechanism 533 and the terminal clamping claw 531 to rotate in the opposite direction, so that the terminal clamping claw 531 and the terminal on the terminal clamping claw 531 face upward.

A limiting hole 541f is provided on the side of the conical shell 541b. The limiting hole 541f is connected to the stepped hole 541e, and the length direction of the limiting hole 541f is in the up and down direction. A limiting column 541g is provided on the pressing head 541a and passes through the limiting hole 541f. The first elastic member 541c is arranged in the stepped hole 541e and forces the conical shell 541b to move downward. The second horizontal linear driving mechanism 542 is used to drive the second lifting driving mechanism 543 and the pressing head group 541 to move back and forth between the first rotating clamping mechanism 530 and the skeleton on the flow carrier 121a. The second lifting driving mechanism 543 is used to drive the pressing head group 541 to descend so that the terminal on the terminal clamp 531 enters the lower end of the stepped hole 541e and presses the terminal into the terminal slot.

[0036] The connecting line between the circular conveying mechanism 120 and the first rotating clamping mechanism 530 is parallel to the driving direction of the second horizontal linear driving mechanism 542. The second horizontal linear driving mechanism 542 drives the second lifting driving mechanism 543 and the pressure head group 541 to move back and forth between the circular conveying mechanism 120 and the first rotating clamping mechanism 530. The second lifting driving mechanism 543 drives the pressure head group 541 to rise and fall so that the pressure head group 541 can take over the terminal on the terminal clamp 531 and press the terminal into the terminal slot.

[0037] When the terminal punching mechanism 540 is working, the first elastic member 541c forces the conical shell 541b to move downward, the limiting column 541g abuts against the top of the limiting hole 541f, and the lower end of the pressing head 541a retreats into the stepped hole 541e, so that the lower end of the stepped hole 541e is connected with the suction nozzle 541d, and the second lifting drive mechanism 543 drives the pressing head 541a and the conical shell 541b to descend at the same time, and the terminal on the terminal clamp 531 enters the lower end of the stepped hole 541e, and the suction nozzle 541d adsorbs the terminal into the lower end of the stepped hole 541e, and then the second lifting drive mechanism 543 drives the pressing head 541a and the conical shell 541b to rise at the same time, and the second horizontal linear drive mechanism 542 drives the second lifting drive mechanism 543 and the pressing head group 541 to move to the top of the skeleton on the circulation carrier 121a of the circular conveying mechanism 120, so that the stepped hole 541e and the terminal are opposite to the terminal groove of the skeleton, and then the second lifting drive mechanism 543 drives the pressing head 541a and the conical shell 541b to rise. The descending driving mechanism 543 drives the pressure head 541a and the conical shell 541b to descend simultaneously. The conical shell 541b first abuts against the frame, the first elastic member 541c is compressed, and the conical shell 541b rises relative to the pressure head 541a until the limiting column 541g abuts against the bottom of the limiting hole 541f. At this time, the pressure head 541a extends out of the stepped hole 541e and pushes the terminal in the stepped hole 541e out of the stepped hole 541e. The terminal is away from the suction nozzle 541d and is pressed. The head 541a is pressed into the terminal slot, and finally the second lifting drive mechanism 543 drives the pressure head 541a to rise. The pressure head 541a rises relative to the conical shell 541b, and the first elastic member 541c stretches until the limiting column 541g rests on the top of the limiting hole 541f again. Then, the pressure head 541a and the conical shell 541b rise synchronously, so that the lower end of the pressure head 541a is retracted into the stepped hole 541e again, and the stepped hole 541e is connected to the suction nozzle 541d.

[0038] Reference Figure 4The terminal crimping mechanism 540 further includes a second bracket 548 disposed on the machine platform 100 , and the second horizontal linear driving mechanism 542 is disposed on the second bracket 548 .

Since the skeleton has two specifications of different heights, the height of the first pad 547a is the height difference between the two specifications of the skeleton. When the first pad 547a is below the limit block, the pressure head group 541 is used to press or drive the terminal into the skeleton with the higher specification. When the third horizontal linear drive mechanism 547 drives the first pad 547a to move in the reverse direction and the first pad 547a avoids the bottom of the limit block, the pressure head group 541 is used to press or drive the terminal into the skeleton with the lower specification.

[0039] In some of the embodiments, the terminal punching mechanism 540 also includes a third lifting drive mechanism 544, a top plate 545, a fifth horizontal linear drive mechanism 546 and a second pad 546a, the output end of the third lifting drive mechanism 544 is connected to the top plate 545, the top plate 545 is used to lift the flow conveyor 121a on the circular conveying mechanism 120 to position the skeleton on the flow conveyor 121a, the output end of the fifth horizontal linear drive mechanism 546 is connected to the second pad 546a, the fifth horizontal linear drive mechanism 546 is used to drive the second pad 546a to move to the bottom of the top plate 545 to position the top plate 545 above the circular conveying mechanism 120.

[0040] When the third lifting drive mechanism 544 drives the top plate 545 to rise, the top plate 545 will lift up the flow conveyor 121a on the circular conveying mechanism 120, and the flow conveyor 121a will be separated from the circular conveying mechanism 120. The circular conveying mechanism 120 will not be able to continue to drive the flow conveyor 121a to move, thereby positioning the flow conveyor 121a and the frame thereon, so that the pressure head group 541 can press the terminal into the terminal groove of the frame.

[0041] When the top plate 545 rises, the fifth horizontal linear drive mechanism 546 drives the second pad 546a to move to the bottom of the top plate 545, and the top plate 545 can rest on the second pad 546a. When the pressure head group 541 presses the terminal into the terminal slot, the top plate 545 is subjected to a downward force, and the second pad 546a can prevent the top plate 545 from moving downward.

[0042] Reference Figure 4 The terminal crimping mechanism 540 also includes a fourth horizontal linear drive mechanism 549 arranged on the machine 100, the driving direction of the fourth horizontal linear drive mechanism 549 is parallel to the conveying direction of a conveying path 121, the output end of the fourth horizontal linear drive mechanism 549 is connected to the third lifting drive mechanism 544, the fourth horizontal linear drive mechanism 549 drives the third lifting drive mechanism 544 to move in the conveying direction of a conveying path 121, and never adjusts the positions of the third lifting drive mechanism 544, the top plate 545 and the flow conveyor 121a in the conveying direction of a conveying path 121, so as to ensure that the skeleton on the flow conveyor 121a can be directly below the pressure head group 541.

[0043] The output end of the fourth horizontal linear driving mechanism 549 is connected to the second mounting plate. The fifth horizontal linear driving mechanism 546 and the second cushion block 546a are both arranged on the second mounting plate, and the top plate 545 can be against the upper surface of the second mounting plate.

[0044] Reference Figure 1 , Figure 8 and Fig. 9 In some embodiments, the skeleton feeding device 200 includes a first feeding mechanism 210, a transfer conveying mechanism 220, a skeleton detection mechanism 230 and a second feeding mechanism 240. The transfer conveying mechanism 220 is provided with an intermediate transfer tool 221, and the intermediate transfer tool 221 is provided with a rotatable support seat 221a. The first feeding mechanism 210 is used to transport the skeleton to the support seat 221a. The transfer conveying mechanism 220 transports the skeleton on the support seat 221a to an area close to the skeleton detection mechanism 230. The skeleton detection mechanism 230 takes a picture of the skeleton to distinguish the position of the terminal slot on the skeleton. The support seat 221a can rotate to adjust the position of the terminal slot on the skeleton. The linear conveying mechanism 110 is provided with a conveying carrier 111. The second feeding mechanism 240 is used to transport the skeleton on the support seat 221a to the conveying carrier 111.

[0045] The first loading mechanism 210 transports the skeleton to the support seat 221a of the intermediate conveyor 221 of the intermediate conveying mechanism 220. The intermediate conveying mechanism 220 transports the intermediate conveyor 221 and the skeleton on the intermediate conveyor 221 to an area close to the skeleton detection mechanism 230. The skeleton detection mechanism 230 takes a picture of the skeleton to distinguish the position of the terminal slot on the skeleton. When the position of the terminal slot on the skeleton does not meet the specified requirements, the support seat 221a rotates to complete the adjustment of the position of the terminal slot on the skeleton so that the position of the terminal slot on the skeleton meets the specified requirements. Then the second loading mechanism 240 transports the skeleton on the support seat 221a to the conveying carrier 111, so that the position of the terminal slot on the skeleton cooperates with the conveying carrier 111, and the skeleton can be accurately limited on the conveying carrier 111, so that the skeleton can be transported to the area corresponding to the winding device 300 and the transfer and conveying mechanism 130 in an accurate posture, so that the winding device 300 can wind the skeleton, and the transfer and conveying mechanism 130 can accurately grasp the skeleton and place the skeleton on the circulation conveyor 121a in a specific posture.

[0046] Reference Fig. 9 In some embodiments, the intermediate transfer tool 221 is provided with a first in-place sensor 221b, a second in-place sensor 221c and a third in-place sensor 221d. The heights of the first in-place sensor 221b, the second in-place sensor 221c and the third in-place sensor 221d are successively reduced. The third in-place sensor 221d is used to detect the detection port of the skeleton to confirm whether the skeleton falls in the correct position of the support seat 221a. The first in-place sensor 221b and the second in-place sensor 221c are respectively used to detect inductors of two different height specifications.

[0047] When the skeleton falls on the correct position of the support base 221a, the third in-place sensor 221d can sense a signal, the first in-place sensor 221b can sense a signal, proving that the skeleton on the support base 221a is of a higher specification, and the second in-place sensor 221c can sense a signal, proving that the skeleton on the support base 221a is of a lower specification.

[0048] Reference Fig.10 and Fig.11 In some embodiments, the conveying carrier 111 includes multiple groups of clamping arms, and a second elastic member is provided between two clamping arms of a group of clamping arms. The second elastic member forces the two clamping arms to approach each other to clamp the skeleton. The machine 100 is provided with an opening clamping jaw 140 in the area corresponding to the second loading mechanism 240. The opening clamping jaw 140 is used to open the two clamping arms so that the skeleton can enter or exit between the two clamping arms.

[0049] When the second loading mechanism 240 places the frame directly between the two clamping arms, the clamping jaws 140 open the two clamping arms so that the frame enters the area between the two clamping arms and is clamped by the two clamping arms. The clamping jaws 140 are arranged in the area corresponding to the frame to be removed, such as in the two areas corresponding to the winding device 300 and the transfer mechanism 130 on the machine 100. The clamping jaws 140 open the two clamping arms to remove the frame from the two clamping arms.

The conveying directions of the transfer conveying mechanism 220 and the linear conveying mechanism 110 are parallel to each other, and the driving direction of the sixth horizontal linear drive mechanism 241 is perpendicular to the conveying direction of the linear conveying mechanism 110. The rotation axis of the second rotary cylinder 243 is parallel to the conveying direction of the transfer conveying mechanism 220, and the second rotary cylinder 243 can drive the first skeleton clamp 244 to rotate, so that the skeleton changes from an upright posture on the intermediate conveyor 221 to a lying state on the conveying carrier 111.

[0052] It is conceivable that the structure of the transfer mechanism 130 is similar to the second loading mechanism 240. The transfer mechanism 130 transfers the semi-finished product lying on the conveying carrier 111 to the circulation conveyor 121a, and the frame on the circulation conveyor 121a is in an upright position.

[0057] The seventh horizontal linear drive mechanism 910, the fifth lifting drive mechanism 920, the eighth horizontal linear drive mechanism 930 and the good product clamp 940 can transport the good products on the circulation transport 121a to the front of the flying line clamp 961. The flying line clamp 961 clamps the thread ends on the thread end columns on the skeleton, and then the seventh horizontal linear drive mechanism 910, the fifth lifting drive mechanism 920, the eighth horizontal linear drive mechanism 930 and the good product clamp 940 move the good products to the front of the flying line clamp 961, so that the thread ends fall off the thread end columns, and the flying line clamp 961 releases the thread ends, and the thread ends can fall into the flying line collecting groove 962. Finally, the seventh horizontal linear drive mechanism 910, the fifth lifting drive mechanism 920, the eighth horizontal linear drive mechanism 930 and the good product clamp 940 transport the good products after the flying lines are pulled out to the unloading conveyor belt 950.
