Description

An apparatus for producing inductor lead strips Technical Field

[0001] This invention relates to the field of inductor lead strip manufacturing technology, specifically an inductor lead strip production apparatus. Background Technology

[0002] The inductor lead strip is a strip developed by the applicant with multiple inductor leads distributed on it. Processing the inductor lead strip using existing production equipment requires multiple processes. When processing inductor lead strips of different widths, the cutting tools for each process need to be changed. Therefore, the existing equipment has the following shortcomings:

[0003] First, the multi-process processing method using assembly line operations requires multiple punching devices, which not only consumes a lot of energy but also increases the cost of the equipment.

[0004] Secondly, the long tool replacement time affects production efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide an inductor lead strip production device with fast tool change.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: an inductor lead strip production apparatus, including a fixed blade changing device and a moving blade changing device. The fixed blade changing device includes a fixed blade changing roller, a support frame, and a fixed blade changing drive motor. The fixed blade changing roller is mounted on the support frame. Multiple circumferential planes are distributed along the circumferential direction on the fixed blade changing roller. Different types of fixed blade assemblies are provided on each of the circumferential planes. The fixed blade changing drive motor drives the fixed blade changing roller to rotate by a preset angle, so as to rotate the required type of fixed blade assembly to the top of the fixed blade changing roller and make the circumferential plane where the fixed blade assembly is located... The plane remains horizontal; the moving blade changing device includes a moving blade changing roller, a U-shaped moving blade holder, and a moving blade changing drive motor. The moving blade changing roller is mounted on the U-shaped moving blade holder. The structure of the moving blade changing roller is the same as that of the fixed blade changing roller. Different types of moving blade assemblies are mounted on each circumferential plane of the moving blade changing roller. The moving blade changing drive motor is used to drive the moving blade changing roller to rotate by a preset angle so that the required type of moving blade assembly is rotated to the bottom of the moving blade changing roller and the circumferential plane where the moving blade assembly is located remains horizontal. The fixed blade assembly cooperates with the moving blade assembly to perform hole cutting on the surface of the aluminum strip.

[0007] Further, the moving blade assembly includes a base plate, on which are disposed an I-shaped cutting blade, a front circular cutting blade, a rear circular cutting blade, a front elongated cutting blade, and a rear elongated cutting blade. The front circular cutting blade and the rear circular cutting blade are respectively located at the front middle and rear middle of the I-shaped cutting blade. The front elongated cutting blade is close to the front left or front right of the I-shaped cutting blade, and the rear elongated cutting blade is close to the rear left or rear right of the I-shaped cutting blade. The I-shaped cutting blades are connected to the I-shaped cutting blades in the fixed blade assembly. A fixed blade, in conjunction with the aluminum strip, cuts an H-shaped hole on the surface of the aluminum strip, thereby cutting out an inductor front lead and an inductor rear lead in one operation. The front circular hole-shaped cutting blade and the rear circular hole-shaped cutting blade, in conjunction with the front circular hole-shaped cutting fixed blade and the rear circular hole-shaped cutting fixed blade in the fixed blade assembly, respectively, cut out a front positioning hole and a rear positioning hole in one operation on the aluminum strip. The front elongated hole-shaped cutting blade and the rear elongated hole-shaped cutting blade, in conjunction with the front elongated hole-shaped cutting fixed blade and the rear elongated hole-shaped cutting fixed blade in the fixed blade assembly, respectively, cut out a resilient front elongated hole and a resilient rear elongated hole in one operation on the aluminum strip.

[0008] Furthermore, the fixed tool changing roller and the moving tool changing roller are hexagonal prism structures, with 6 moving tool assemblies and 6 fixed tool assemblies respectively provided on the fixed tool changing roller and the moving tool changing roller. The 6 moving tool assemblies and 6 fixed tool assemblies constitute six types of tool assemblies.

[0009] Furthermore, the fixed blade changing roller and the moving blade changing roller are hollow structures made of aluminum alloy.

[0010] Furthermore, an inductor lead strip production apparatus further includes a material tray, aluminum strip, an intermittent feeding device, a cutting device, a linkage coordination device, and an inductor lead strip winding device. The aluminum strip is wound on the material tray. The intermittent feeding device is used to intermittently drive the aluminum strip to transport it to the cutting device. The cutting device includes a hydraulic cylinder and a punch head. The hydraulic cylinder drives the moving blade changing device to move through the punch head, thereby driving the moving blade assembly to rise and fall. The support frame in the fixed blade changing device is mounted on the machine base, and the fixed blade assembly in the fixed blade changing device is located directly below the moving blade assembly. The inductor lead strip formed after the moving blade assembly and the fixed blade assembly cut the aluminum strip is wound by the inductor lead strip winding device. The linkage coordination device is used to activate the intermittent feeding device when the moving blade assembly rises to a predetermined height, thereby driving the aluminum strip to move by a preset feed amount.

[0011] Furthermore, the linkage coordination device adopts a through-beam photoelectric sensor. The light emitting unit and the light receiving unit in the through-beam photoelectric sensor are located on both sides of the moving blade changing device. When the moving blade assembly rises without blocking the light path, and the light receiving unit receives the light, the light receiving unit sends a signal to the main controller, and the main controller starts the intermittent feeding device to feed the material.

[0012] Furthermore, the intermittent feeding device includes a feeding roller group and a servo motor. The servo motor provides power to the feeding roller group. The feeding roller group includes an active roller and a passive roller. The active roller and the passive roller cooperate to drive the aluminum strip to move intermittently.

[0013] Furthermore, the U-shaped moving cutter holder is mounted on a pressure regulating seat. The pressure regulating seat has through holes at its four corners. Bolts pass downwards through these through holes and are threaded into screw holes on the upper surface of the U-shaped moving cutter holder. A buffer spring is fitted onto the bolt, located between the U-shaped moving cutter holder and the pressure regulating seat. A pressure sensor is installed between the U-shaped moving cutter holder and the pressure regulating seat. This pressure sensor monitors the pressure of the U-shaped moving cutter holder in real time and transmits the pressure signal to the main controller. The main controller controls the auxiliary hydraulic cylinder according to a preset pressure value. The auxiliary hydraulic cylinder is installed between the pressure regulating seat and the stamping head. By adjusting the output pressure of the auxiliary hydraulic cylinder, the pressure of the moving cutter assembly on the aluminum strip is precisely controlled.

[0014] Furthermore, a waste material collection box is provided below the fixed blade changing roller. The fixed blade changing roller rotates at a certain angle, causing the waste material on the fixed blade changing roller to slide into the waste material collection box.

[0015] Furthermore, both the fixed tool changing drive motor and the moving tool changing drive motor are servo motors.

[0016] The beneficial effects of this invention are as follows: This application adopts a centralized cutting tool, which can cut out the shape of the inductor pins and the required holes on the strip in one go, greatly improving work efficiency and reducing equipment costs at the same time; In particular, the fixed tool changing device and the moving tool changing device in this application adopt a multi-prism roller structure, and various types of tool assemblies are installed on the roller. Without disassembling the tool, the tool can be changed quickly by rolling, which greatly improves work efficiency. This application can process various types of inductor pin strips of different widths by changing the tool. Attached Figure Description

Therefore, they should not be construed as limitations on this invention.

[0021] Before describing the inductor lead strip manufacturing equipment, let's first introduce the inductor lead strip to be produced.

[0022] As shown in Figure 1, the inductor lead strip includes an aluminum strip with a width of 10mm-50mm and a thickness of 0.2mm-0.8mm. The aluminum strip is cut into a front edge longitudinal strip 1, a rear edge longitudinal strip 2, multiple transverse connecting strips 3, multiple inductor front leads 4, and multiple inductor rear leads 5. The front edge longitudinal strip 1 is connected to the rear edge longitudinal strip 2 through multiple transverse connecting strips 3. The multiple transverse connecting strips 3 are parallel to each other and spaced apart. The multiple inductor front leads 4 are spaced apart on the front edge longitudinal strip 1 and extend towards the rear edge longitudinal strip 2. The multiple inductor rear leads 5 are spaced apart on the rear edge longitudinal strip 2 and extend towards the front edge longitudinal strip 1. An inductor front lead 4 and an inductor rear lead 5 corresponding to the inductor front lead 4 are provided between adjacent transverse connecting strips 3. Multiple front positioning holes 6 and multiple rear positioning holes 7 are distributed on the front edge longitudinal strip 1 and the rear edge longitudinal strip 2, respectively. The front positioning holes 6 and the rear positioning holes 7 correspond to each other, with the front positioning holes 6 near one end of the inductor front pin 4 and the rear positioning holes 7 near one end of the inductor rear pin 5. A resilient front elongated hole 8 is provided on the front edge longitudinal strip 1 near one end of the transverse connecting strip 3, and a resilient rear elongated hole 9 is provided on the rear edge longitudinal strip 2 near the other end of the transverse connecting strip 3. The resilient rear elongated hole 9 and the resilient front elongated hole 8 are used to give the transverse connecting strip 3 a certain degree of resilience. A front solder joint 10 and a rear solder joint 11 are provided on the inductor front pin 4 and multiple inductor front pins 5, respectively. The front solder joint 10 is used to solder to one end of the inductor coil, and the rear solder joint 11 is used to solder to the other end of the inductor coil. The width of the plurality of transverse connecting strips 3 is the same, the width of the inductor front pin 4 and the inductor rear pin 5 is the same, and the width of the inductor rear pin 5 is not less than 5 times the width of the transverse connecting strips 3.

[0023] As shown in Figure 2, an inductor lead strip production apparatus includes a fixed blade changing device 12 and a moving blade changing device 13, as well as a material tray 14, an aluminum strip 15, an intermittent feeding device 16, a cutting device 19, a linkage coordination device 17, and an inductor lead strip winding device 18. The aluminum strip 15 is wound on the material tray 14. The intermittent feeding device 16 is used to intermittently drive the aluminum strip 15 to transport the aluminum strip 15 to the cutting station of the cutting device. The inductor lead strip formed by the moving blade assembly and the fixed blade assembly in the cutting device 19 after cutting the aluminum strip 15 is wound by the inductor lead strip winding device 18. The linkage coordination device 17 is used to activate the intermittent feeding device 16 when the moving blade assembly rises to a predetermined height, so as to drive the aluminum strip 15 to move by a preset feed amount. Specifically, the linkage coordination device uses a through-beam photoelectric sensor. The light emitting unit and the light receiving unit in the through-beam photoelectric sensor are located on both sides of the moving blade changing device. When the moving blade assembly rises without blocking the light path, the light receiving unit receives the light and sends a signal to the main controller. The main controller then starts the intermittent feeding device to feed the material.

[0024] The intermittent feeding device 16 includes a feeding roller group 21 and a servo motor 22. The servo motor 22 provides power to the feeding roller group 21. The feeding roller group includes an active roller and a passive roller. The active roller and the passive roller cooperate to drive the aluminum strip to move intermittently.

[0025] The support frame in the fixed tool changing device 12 is mounted on the machine base 20, and the fixed tool assembly in the fixed tool changing device is located directly below the moving tool assembly.

[0026] Below the fixed blade changing roller 24 in the fixed blade changing device 12 is a cutting waste collection box 23. The fixed blade changing roller 24 rolls at a certain angle, so that the cutting waste on the fixed blade changing roller 24 slides into the cutting waste collection box 23.

[0027] As shown in Figure 3, the fixed blade replacement device 12 includes a fixed blade replacement roller 24, a support frame 25, and a fixed blade replacement drive motor 26. The fixed blade replacement roller 24 is mounted on the support frame 25. The fixed blade replacement roller 24 has multiple circumferential planes distributed along the circumferential direction. Different types of fixed blade assemblies 27 are provided on each of the circumferential planes. The fixed blade replacement drive motor 26 is used to drive the fixed blade replacement roller 24 to rotate by a preset angle so as to rotate the required type of fixed blade assembly 27 to the top of the fixed blade replacement roller 24 and keep the circumferential plane where the fixed blade assembly 27 is located horizontal.

[0028] As shown in Figure 4, the cutting device 19 includes a hydraulic cylinder 28 and a punch head 29. The moving blade changing device 13 includes a moving blade changing roller 30, a U-shaped moving blade holder 31, and a moving blade changing drive motor 32.

Different types of moving blade assemblies 33 are provided on each circumferential plane of the moving blade changing roller 30. The moving blade changing drive motor 32 is used to drive the moving blade changing roller 30 to rotate at a preset angle so that the required type of moving blade assembly 33 is rotated to the bottom of the moving blade changing roller 30 and the circumferential plane where the moving blade assembly is located is kept horizontal. The fixed blade assembly 27 cooperates with the moving blade assembly 33 to perform hole cutting on the surface of the aluminum strip 15.

[0029] The U-shaped moving cutter holder 31 is mounted on the pressure regulating seat 34. The pressure regulating seat 34 has through holes 35 at its four corners. Bolts 36 pass downward through the through holes 35 and are threaded into the screw holes on the upper surface of the U-shaped moving cutter holder 31. A buffer spring 37 is fitted on the bolt 36. The buffer spring 37 is located between the U-shaped moving cutter holder 31 and the pressure regulating seat 34. A pressure sensor 38 is provided between the U-shaped moving cutter holder 31 and the pressure regulating seat 34. The pressure sensor 38 is used to monitor the pressure of the U-shaped moving cutter holder 31 in real time and transmit the pressure signal to the main controller 39. The main controller 39 controls the auxiliary hydraulic cylinder 40 according to the preset pressure value. The auxiliary hydraulic cylinder 40 is installed between the pressure regulating seat 34 and the punch head 29. By adjusting the output pressure of the auxiliary hydraulic cylinder 40, the pressure of the moving cutter assembly 33 on the aluminum strip 15 can be precisely controlled.

[0030] The hydraulic cylinder 28 drives the pressure regulating seat 34 through the punching head 29. The pressure regulating seat 34 drives the U-shaped moving knife seat 31, thereby driving the moving knife assembly 33 on the moving knife changing roller 30 to rise and fall, thus realizing the punching action of the moving knife assembly 33.

[0031] In this embodiment, both the fixed-blade changing drive motor 26 and the moving-blade changing drive motor 32 are servo motors. When the fixed-blade changing drive motor and the moving-blade changing drive motor are not working, or when punching is being performed, the fixed-blade changing roller and the moving-blade changing roller are locked by a brake to prevent them from rotating.

The front elongated cutting blade 45 is close to the front left or front right side of the I-shaped cutting blade 42, and the rear elongated cutting blade 46 is close to the rear left or rear right side of the I-shaped cutting blade 42. The I-shaped cutting blade 42 and the fixed blade assembly 27 are connected to the I-shaped cutting blade 42. The cutting blade 47, in conjunction with the aluminum strip, cuts an H-shaped hole on the surface of the aluminum strip to cut an inductor front lead 4 and an inductor rear lead 5 on the aluminum strip 15 in one go; the front circular hole cutting blade 43 and the rear circular hole cutting blade 44, in conjunction with the front circular hole cutting blade 48 and the rear circular hole cutting blade (not shown in the figure) in the fixed blade assembly, respectively, cut a front positioning hole 6 and a rear positioning hole 7 on the aluminum strip in one go; the front elongated hole cutting blade 45 and the rear elongated hole cutting blade 46, in conjunction with the front elongated hole cutting blade 49 and the rear elongated hole cutting blade (not shown in the figure) in the fixed blade assembly, respectively, cut a resilient front elongated hole 8 and a resilient rear elongated hole 9 on the aluminum strip in one go.
