Description

Technical Field

[0001] This utility model relates to the technical field of inductor board insertion, and in particular to a lead-cutting mechanism for an inductor board insertion machine. Background Technology

[0002] An inductor is a component that converts electrical energy into magnetic energy and stores it. An inductor has a certain inductance; it only impedes changes in current. If no current flows through the inductor, it will attempt to impede the current flow when the circuit is closed. If current flows through the inductor, it will attempt to maintain a constant current when the circuit is open. In the production of products containing electronic components, inductors need to be fixed by passing their pins through a plastic sheet for easy positioning and installation. However, the pins need to be trimmed before passing through the plastic sheet. This manual operation is inefficient, and the inconsistent trimming lengths affect the quality of the insertion process.

[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] like Figures 1 to 6 As shown in this embodiment, a shearing mechanism for an inductor threading machine includes front and rear guide rails 1, a slider connecting plate 2, and a shearing upper plate 3. The slider connecting plate 2 slides along the front and rear guide rails 1. The shearing upper plate 3 is fixed above the slider connecting plate 2. A clamping cylinder 4 is installed on the shearing upper plate 3. An upper pressure block 5 is connected to the driving end of the clamping cylinder 4. A wire positioning plate 6 is fixed in the middle of the shearing upper plate 3. Wire foot pressure plates 7 are movably connected to the front and rear ends of the wire positioning plate 6. A lifting plate 8 is provided between the shearing upper plate 3 and the slider connecting plate 2. The lifting plate 8 moves in the vertical direction. Pull plates 9 move laterally on both sides of the lifting plate 8. A cutter head 10 is slidably connected to the pull plate 9. A side pressure block 11 is elastically connected to the cutter head 10. The side pressure block 11 is inserted into the inside of the wire foot pressure plate 7.

[0026] The inductor 18 is placed in the middle of the upper plate 3 of the cutting foot, with the pins of the inductor 18 on the wire positioning plate 6. The clamping cylinder 4 is rotated and the inductor 18 is fixed by the upper pressure block 5. The wire positioning plate 7 moves towards the middle from the front and back, restricting the pins of the inductor 18 in the pin holes of the wire positioning plate 6. The cutter head 10 moves from both sides towards the middle. When the side pressure block 11 is inserted into the slot between the wire positioning plate 6 and the wire positioning plate 7, the pin position is fixed. Then the cutter head 10 continues to move forward. At this time, the lifting plate 8 drives the pulling plate 9 to move downward, and the front end of the cutter head 10 cuts the pins.

[0027] The upper cover plate 12 is connected to the wire positioning plate 6. The upper pressure block 5 is pressed on the middle of the upper cover plate 12. The front and rear ends of the upper plate 3 are fixed with pressure plate cylinders 13. The driving end of the pressure plate cylinder 13 is fixedly connected to the wire foot pressure plate 7. The end of the wire positioning plate 6 is located in the guide groove of the wire foot pressure plate 7. The upper cover plate 12 restricts the pressing position of the upper pressure block 5 and can be aligned with the inductor 18. The forward and backward movement of the wire foot pressure plate 7 is driven horizontally by the pressure plate cylinder 13.

[0028] The cutter head 10 has a guide shaft 14 fixed inside. The lower end of the side pressure block 11 slides on the guide shaft 14. A load spring 15 is sleeved on the guide shaft 14. The load spring 15 is elastically connected to the side pressure block 11. The front end of the side pressure block 11 is provided with a push angle. A V-shaped slot is formed between the wire foot pressure plate 7 and the wire position plate 6. The push angle is inserted into the V-shaped slot. After the push angle part of the side pressure block 11 is inserted into the V-shaped slot between the wire foot pressure plate 7 and the wire position plate 6, the position of the needle is fixed. Then the load spring 15 retracts. While the side pressure block 11 remains fixed, the cutter head 10 continues to move forward to cut the fixed needle.

[0029] Both sides of the upper plate 3 of the scissor are fixed with blade cylinders 16. The blade 10 is fixed on the drive end of the blade cylinder 16. The lateral movement of the blade 10 and the side pressure block 11 is powered by the blade cylinder 16.

[0030] The front end and rear end of the pull plate 9 are provided with a first inclined surface 17, and the lower front end and the lower rear end of the cutter head 10 are provided with a second inclined surface. The first inclined surface 17 and the second inclined surface slide relative to each other. After the side pressure block 11 fixes the needle, the cutter head 10 continues to move forward. Under the inclined force of the first inclined surface 17 and the second inclined surface, the lateral movement of the cutter head 10 will force the pull plate 9 to move downward, so that the cutter head 10 can continue to move forward and cut the needle.

[0031] A first spring bolt 19 is fixed to the lower end of the pull plate 9, and a second spring bolt 20 is fixed to the lifting plate 8. A tension spring 21 is connected between the first spring bolt 19 and the second spring bolt 20. When the cutter head 10 finishes cutting and retracts, the tension spring 21 also pulls the pull plate 9 back to achieve reset.

[0032] A guide plate 22 is fixed in the middle of the upper plate 3 of the shear head, and the cutter head 10 moves in the middle of the guide plate 22. A mounting plate 23 is fixed below the guide plate 22. A spring rod 24 is connected between the lifting plate 8 and the mounting plate 23. A lifting spring 25 is sleeved on the outside of the spring rod 24. A lifting cylinder 26 is fixed on the mounting plate 23. The drive end of the lifting cylinder 26 is connected to the lifting plate 8. The guide plate 22 guides the movement of the cutter head 10. The mounting plate 23 restricts the lifting of the lifting plate 8. The lifting cylinder 26 provides lifting thrust and, together with the spring rod 24 and the lifting spring 25, resets the lifting plate 8.

[0033] A shearing cylinder 27 is provided behind the slider connecting plate 2. The drive end of the shearing cylinder 27 is fixedly connected to the slider connecting plate 2. A buffer 28 and a stop bolt 29 are installed on the side of the shearing cylinder 27. When the inductor 18 is loaded onto the shearing plate 3, the shearing cylinder 27 controls the slider connecting plate 2 to move forward. When the inductor 18 is in place and shearing is required, the shearing cylinder 27 drives the slider connecting plate 2 to move backward under the action of the front and rear guide rails 1, and stops under the action of the buffer 28 and the stop bolt 29.

[0034] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles applied thereto. Within the scope of the technology disclosed in this utility model, any variations or substitutions that are easily conceived by those skilled in the art should be covered within the protection scope of this utility model.
