[0002] At present, the machines for producing power inductors on the market have the problems of difficult tool setting, easy tool damage, and difficulty in fixing the coil tail during cutting. During the cutting operation, the coil tail is easy to move, thereby causing the tail cutting length to be inconsistent, the need for secondary processing, the influence on production efficiency, and the difficulty in collecting the cut-off wire ends, thereby causing resource waste.
[0003] To solve the above problems, the invention with the publication number "CN114029427A" discloses a wire cutting mechanism for power inductor production, which comprises a sliding rail, a bottom plate, a baffle and a fixing seat.

DETAILED DESCRIPTION
[0017] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all.

[0019] The winding assembly is composed of a skeleton 7, a winding shaft 19, a wire clamping block 17, and a driving mechanism. It is used for winding an inductor coil. A pair of winding shafts 19 are rotatably connected on one side of the workbench 6. A pair of skeletons 7 are clamped on the winding shaft 18. A pair of wire clamping blocks 17 are fixedly arranged on the workbench 6 and are each provided with a wire clamping groove 18. The inductor coil is wound on the skeleton 7 through the wire clamping groove 18.
[0020] The driving mechanism includes a driving motor 26 and a pair of pulleys 27. The driving motor 26 is fixedly installed on the rack 1 and the output shaft is coaxially fixedly connected with one pulley 27. The pair of pulleys are drivingly connected through a belt and are respectively coaxially fixedly connected with a pair of winding shafts.
[0021] The tangent line assembly is composed of a cutter module 12 for flattening cutting the inductance line, the cutter module 12 comprising a straightening block 1201, a tangent line blade 1202 and a straightening groove 1203, a pair of tangent line blades 1202 being fixedly arranged at one side of the lower end of the T-shaped block 10, the straightening block 1201 being fixedly arranged at both sides of the tangent line blade 1202, the straightening groove 1203 being arranged on the wire clamping block 17 and communicating with the wire clamping groove 18, the straightening groove 1203 being inserted into the straightening block 1201.
[0022] The lower end of the T-shaped block 10 is provided with a pressing module 11, the pressing module 11 comprising a pressing block 1101, a sliding rod 1102 and a pressing spring 1103, a pair of pressing blocks 1101 being arranged below the T-shaped block 10 and the upper end of the pressing block 1101 being vertically and slidingly connected with the sliding rod 1102, the pressing spring 1103 being sleeved outside the sliding rod 1102 and being elastically arranged between the pressing block 1101 and the T-shaped block 10.
[0023] There is a height difference between the lower end surface of the pressing block 1101 and the lower end surface of the tangent line blade 1202, and the position of the pressing block 1101 is lower than the lower end surface of the tangent line blade 1201.
[0024] In the embodiment, first, the skeleton 7 to be wound with the coil is clamped on a pair of winding shafts 19, then one end of the inductance line is pulled out and passes through the wire clamping groove 18 on the wire clamping block 17 and is preliminarily fixed on the skeleton 7; the driving motor 26 in the driving mechanism is started, the output shaft of the driving motor 26 drives a belt pulley 27 coaxially fixed therewith to rotate, the belt pulley 27 drives another belt pulley 27 to rotate synchronously through a belt, and the two belt pulleys 27 drive a pair of winding shafts 19 coaxially fixed therewith to rotate, respectively, the winding shafts 19 drive the skeleton 7 to rotate, so that the inductance line is wound on the skeleton 7 along the wire clamping groove 18, and the winding operation of the inductance coil is realized. When the coil winding reaches the preset requirement, the hydraulic rod 9 on the L-shaped stand 8 is controlled to extend, and the extension end of the hydraulic rod 9 drives the T-shaped block 10 to move downward.
[0025] During the downward movement of the T-shaped block 10, the pressing module 11 at the lower end of the T-shaped block 10 first contacts the inductance line, the pressing block 1101 slides upward along the sliding rod 1102 after being subjected to the reaction force of the inductance line, and the external pressing spring 1103 is compressed at the same time, the elastic reaction force of the pressing spring 1103 enables the pressing block 1101 to firmly fix the inductance line at the wire clamping block 17, so as to avoid the movement of the inductance line during subsequent tangent line cutting; the T-shaped block 10 continues to move downward, driving the cutter module 12 to move downward synchronously, at this time, the straightening blocks 1201 at both sides of the cutter module 12 are first inserted into the straightening grooves 1203 on the wire clamping block 17, and the straightening grooves 1203 cooperate with the straightening blocks 1201 to accurately straighten the inductance line, preventing the inductance line from being bent to cause tangent line deviation.
[0026] With the T-shaped block 10 further down, the tangent blade 1202 between the straightening block 1201 contacts the straightened inductance line, and the inductance line is cut flat, completing the tangent cutting operation; after the tangent cutting is completed, the hydraulic rod 9 is controlled to be shortened, driving the T-shaped block 10, the pressing module 11 and the cutter module 12 to reset, and the inductance coil wound and completed tangent cutting can enter the next operation cycle.
[0027] Embodiment 2 Reference Figures 3-4 The difference from embodiment 1 is that this embodiment also includes a trigger assembly composed of an elastic air bag 20, a position sensor 22 and a sensing ball 23, which is used to trigger the hydraulic rod 9 to press down for tangent cutting. The air bag box 16 is fixedly installed on the rack 1, the elastic air bag 20 is transversely arranged in the air bag box 16 and provided with a one-way air outlet valve 21 at the tail, the position sensor 22 is fixed on the side wall of the air bag box 16 near the tail of the elastic air bag 20, the sensing ball 23 is fixedly arranged at the head of the elastic air bag 20, and the elastic air bag 20 is drivingly connected with the transmission mechanism through the bending rod 25.
[0028] The transmission mechanism includes a gear 28 and a rack 29. The gear 28 is fixedly connected with the driving motor 26 through a one-way bearing, the rack 29 is slidingly connected with the rack 1, and the gear 28 is engaged with the rack 29.
[0029] In this embodiment, first, the same as step one of embodiment 1, the skeleton 7 is clamped on the winding shaft 19 and the inductance line is fixed at one end, the driving motor 26 is started, the driving motor 26 drives the winding shaft 19 to rotate through the belt pulley 27 on one side, so that the skeleton 7 completes the winding of the inductance coil; on the other side, the output shaft of the driving motor 26 drives the gear 28 connected through the one-way bearing to rotate, the gear 28 is engaged with the rack 29 slidingly connected with the rack 1, and then drives the rack 29 to slide linearly along the rack 1.
[0030] During the sliding of the rack 29, the elastic air bag 20 is pushed to be compressed transversely in the air bag box 16 through the bending rod 25, and when the elastic air bag 20 is compressed, the gas in the elastic air bag 20 is slowly discharged through the one-way air outlet valve 21 at the tail; with the increase of the winding turns of the coil, the driving motor 26 drives the gear 28 to rotate synchronously, the sliding distance of the rack 29 gradually increases, and the compression amount of the elastic air bag 20 also increases, and the sensing ball 23 at the head of the elastic air bag 20 moves towards the position sensor 22 near the tail of the air bag box 16.
[0031] When the coil winding reaches the preset fixed number of turns, the elastic air bag 20 is compressed to the trigger position sensor 22 of the sensing ball 23, and the position sensor 22 sends a signal to the control end, and the control end automatically controls the extension of the hydraulic rod 9 on the L-shaped stand 8. The subsequent processes of the fixing module 11 fixing the inductance line and the cutter module 12 straightening and cutting the inductance line are consistent with embodiment 1, and the automatic cutting line triggering under the fixed number of turns is realized.
[0032] After the cutting line is completed, the driving motor 26 is paused or reversed, the one-way bearing causes the gear 28 to be disconnected from the output shaft of the driving motor 26, the elastic air bag 20 is no longer pushed by the bending rod 25, the external air can be supplemented to the inside of the air bag, the rack 29 is reset through the bending rod 25, the gear 28 is reversely slid with the rack 29, and the next winding operation is started. When the above trigger process is repeated.
[0033] Embodiment 3 Reference Figure 5 The difference between the embodiment and embodiments 1 and 2 is that the embodiment further includes a negative pressure assembly, the negative pressure assembly is composed of a drawer box 13, a dust suction hopper 30, an air suction pipe 31 and a dust discharge pipe 32, and is used for sucking and removing the cutting line scraps. The drawer box 13 is fixedly arranged on the storage rack 5, the dust suction hopper 30 is fixed on the line clamping block and is obliquely opened to the position of the straightening groove 1203, the air suction pipe 31 is communicatively arranged between the tail of the elastic air bag 20 and the upper end of the drawer box 13, and the dust discharge pipe 32 is communicatively arranged between the drawer box 13 and the dust suction hopper 30.
[0034] The inner diameter of the dust discharge pipe 32 is 8-12 mm, and the diameter of the pipe opening of the dust discharge pipe 32 close to the dust suction hopper 30 is larger than the diameter of the pipe opening close to the drawer box 13. The connection positions of the dust discharge pipe 32 and the dust suction hopper 30 and the drawer box 13 are all provided with sealing rubber rings.
[0035] In the embodiment, first, the skeleton 7 is installed and the inductance line is fixed according to the process of embodiment 1, the driving motor 26 is started, on one hand, the winding shaft 19 is driven to rotate for winding the coil through the belt pulley 27, and on the other hand, the elastic air bag 20 is compressed in the air bag box 16 through the meshing transmission of the gear 28 and the rack 29 and the pushing of the bending rod 25, until the sensing ball 23 triggers the position sensor 22, the control end drives the hydraulic rod 9 to extend, and the fixing module 11 fixes the inductance line, the cutter module 12 straightens and cuts the inductance line.
[0036] In the process of the elastic air bag 20 compression, the gas inside the elastic air bag 20 is discharged through the tail one-way air outlet valve 21, and at the same time, because the one-way valve in the air suction pipe 31 only allows air to flow from the drawer box 13 to the elastic air bag 20, the negative pressure generated by the compression of the elastic air bag 20 will extract air from the drawer box 13 through the air suction pipe 31, so that a negative pressure environment is formed in the drawer box 13; the negative pressure is transmitted to the dust suction hopper 30 through the chip removal pipe 32 which communicates the drawer box 13 with the dust suction hopper 30, and because the opening of the dust suction hopper 30 is obliquely opposite the tangent line operation area of the straightening groove 1203, the copper wire end debris and dust generated in the tangent line process will be sucked into the dust suction hopper 30, and then transported to the drawer box 13 along the chip removal pipe 32 for collection.
[0037] In the above, the chip removal pipe 32 is designed with an inner diameter of 8-12 mm, and the diameter of the pipe opening near the dust suction hopper 30 is larger than that near the drawer box 13, which can reduce the risk of blockage during chip transportation and improve the chip transportation efficiency; at the same time, the sealing rubber ring at the connection between the chip removal pipe 32 and the dust suction hopper 30 and the drawer box 13 can avoid negative pressure leakage and ensure stable suction force. When the tangent line is completed, the elastic air bag 20 is paused or reversed by the driving motor 26, external air is supplemented into the elastic air bag 20, the negative pressure of the drawer box 13 disappears, and the collected debris can be cleaned by opening the drawer box 13, completing a complete operation cycle including winding, automatic tangent line triggering and automatic debris cleaning.
[0038] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can make equivalent replacement or change according to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
