Description

Technical Field

[0001] This invention relates to the field of electromagnetic component processing technology, and in particular to an electromagnetic component wire cutting device and an electromagnetic component hanging device. Background Technology

[0002] Electromagnetic components are common in electronic products, such as inductors and transformers. However, some components in these devices often need to be fixed to an insulating base, and the coil ends of the electromagnetic component are connected to the conductive pins of the insulating base to facilitate mounting on the circuit board during application. Taking a common-mode inductor as an example, a common-mode inductor typically has two coils, with each coil having a lead at both ends. In the fabrication of a common-mode inductor, two coils are first wound on a magnetic core, and then the four leads of the two coils are wound onto the four conductive pins of the insulating base (this process is called "pin mounting").

[0003] During the pin-hanging process, after the wire ends are wound onto the conductive pins, the excess wire ends need to be cut off. Then, spot welding is performed on the wound area to achieve an electrical connection between the coil wire ends and the conductive pins. In related technologies, the excess wire ends formed after pin-hanging are usually cut manually, which is inefficient and difficult to automate. Summary of the Invention

[0004] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, the object of this invention is to provide an electromagnetic component wire cutting device and an electromagnetic component pin hanging device.

[0005] To achieve the above objectives, in one aspect, according to an embodiment of the present invention, an electromagnetic component wire end cutting device is provided, wherein the electromagnetic component includes an insulating base and a magnetic core coil, the insulating base has conductive leads, and the wire end of the magnetic core coil is wound around the conductive leads to form a hanging wire end. The electromagnetic component wire end cutting device includes:

[0006] Two fixed tool holders are arranged opposite each other in a first direction and define a workpiece positioning space suitable for positioning the electromagnetic element, each fixed tool holder having a fixed tool head;

[0007] A movable cutting blade is located between two fixed blade holders, and the movable cutting blade has a cutting head with two moving blades arranged back to back in the first direction.

[0008] A driving device is provided to drive the movable cutter to switch between a central position, a first cutting position, and a second cutting position, wherein the first cutting position and the second cutting position are located on both sides of the central position, respectively.

[0009] When the movable cutter moves from the central position to the first cutting position, one of the moving blades in the cutter head holds one lead of the electromagnetic element against the fixed blade of one of the two fixed blade holders and cuts it off; when the movable cutter moves from the central position to the second cutting position, the other moving blade in the cutter head holds the other lead of the electromagnetic element against the fixed blade of the other of the two fixed blade holders and cuts it off.

[0010] In addition, the electromagnetic component wire cutting device according to the above embodiments of the present invention may also have the following additional technical features:

[0011] According to one embodiment of the present invention, there are four conductive pins, and a hanging wire end is formed on each of the four conductive pins;

[0012] Each of the fixed blade holders has two fixed blade heads, which are arranged opposite each other in a second direction, which is perpendicular to the first direction; the movable cutter has two cutter heads, which are arranged opposite each other in the second direction.

[0013] One of the two cutting heads is located between two opposing fixed cutting heads on the two fixed cutting seats, and is used to cut the lead wire ends on two of the four conductive pins; the other of the two cutting heads is located between two other opposing fixed cutting heads on the two fixed cutting seats, and is used to cut the lead wire ends on the other two of the four conductive pins.

[0014] According to one embodiment of the present invention, the fixed cutter head has a stop surface, and the first direction is perpendicular to the stop surface;

[0015] When the electromagnetic element is located within the workpiece positioning space, the conductive pin is located inside the stop surface and is close to the stop surface.

[0016] According to one embodiment of the present invention, the fixed blade has an inclined surface, the inclined surface intersects with the stop surface to form a fixed cutting edge, and the moving cutting edge is substantially opposite to the fixed cutting edge in the first direction.

[0017] According to one embodiment of the present invention, the bottom of the cutting head has a groove for cooperating with the fixed cutting head, the groove being open to one side facing the fixed cutting head to form an open side, and the moving cutting edge being formed on the inner wall of the groove.

[0018] According to one embodiment of the present invention, the bottom of the cutting head is provided with a slit, the slit is connected to the cutting groove and is open in the second direction, so as to avoid the hanging wire head when the electromagnetic element is inserted into the workpiece positioning space.

[0019] According to one embodiment of the present invention, the fixed tool holder is provided with a positioning groove for positioning the insulating seat, and the two fixed tool heads are located on both sides of the positioning groove in the second direction.

[0020] According to one embodiment of the present invention, it further includes:

[0021] A base having a downwardly penetrating swing groove;

[0022] A swing arm, which passes through the swing groove and whose upper end is pivotable about an axis extending along the second direction;

[0023] Two fixed blade holders are installed at the lower end of the base and located on both sides of the swing groove in the first direction. The movable cutter is installed at the lower end of the swing arm. The driving device drives the swing arm to swing within the swing groove so that the movable cutter switches between the central position, the first cutting position, and the second cutting position.

[0024] According to one embodiment of the present invention, the driving device includes:

[0025] A first elastic component is disposed between the base and one side of the swing arm;

[0026] A second elastic component is disposed between the base and the other side of the swing arm. The elastic forces provided by the first elastic component and the second elastic component are in opposite directions, and the swing arm is positioned in the central position.

[0027] A driver, which is mounted on the base and connected to the swing arm, is used to drive the swing arm to move to one side of the first direction against the elastic force of the first elastic component, or to move to the other side of the first direction against the elastic force of the second elastic component.

[0028] On the other hand, the electromagnetic component mounting device according to an embodiment of the present invention includes:

[0029] The hanging mechanism is used to assemble the insulating base and the magnetic core and hang the wire ends on the magnetic core coil on the conductive pins of the insulating base to form hanging wire ends;

[0030] The electromagnetic component wire end cutting device described above is used to cut the hanging wire end.

[0031] According to the embodiments of the present invention, the electromagnetic component wire end cutting device and the electromagnetic component lead hanging device have a movable cutting blade located between two fixed blade seats. The movable cutting blade can switch between a central position, a first cutting position, and a second cutting position. When the movable cutting blade moves from the central position to the first cutting position, one moving blade of the cutting head holds one lead hanging wire of the electromagnetic component against the fixed blade of one of the two fixed blade seats and cuts it off. When the movable cutting blade moves from the central position to the second cutting position, the other moving blade of the cutting head holds the other lead hanging wire of the electromagnetic component against the fixed blade of the other of the two fixed blade seats and cuts it off. In this way, the lead hanging wires on the electromagnetic components can be automatically cut off, improving the efficiency of production and processing and the quality of products.

[0072] The electromagnetic component wire cutting device of the present invention will now be described in detail with reference to the accompanying drawings.

[0073] Reference Figures 2 to 8 As shown, according to an embodiment of the present invention, the electromagnetic component wire end cutting device includes an electromagnetic component 40 comprising an insulating base 401 and a magnetic core coil 402. The insulating base 401 has conductive pins 401a. The wire end of the magnetic core coil 402 is wound around the conductive pins 401a to form a hanging wire end 402a. The electromagnetic component wire end cutting device includes two fixed blade holders 10, a movable cutting blade 20, and a driving device 30.

[0074] Specifically, the two fixed tool holders 10 are arranged opposite each other in a first direction and define a workpiece positioning space suitable for positioning the electromagnetic element 40, and each fixed tool holder 10 has a fixed tool head 101. That is, after the electromagnetic element 40 is attached, it can be just locked in the workpiece positioning space between the two fixed tool holders 10.

[0075] The movable cutter 20 is located between the two fixed cutter seats 10, and the movable cutter 20 has a cutter head 201, which has two moving blades 201a arranged back to back in the first direction. The movable cutter 20 can swing back and forth between the two fixed cutter seats 10. During the swinging process, the two back-to-back moving blades 201a on the movable cutter 20 respectively cooperate with the fixed cutter seats 10 on both sides, that is, one moving blade 201a cooperates with the fixed cutter seat 10 on the same side opposite to it, and the moving blade 201a is used to cut the hanging wire end 402a on the fixed cutter seat 10.

[0076] The driving device 30 is used to drive the movable cutter 20 to switch between a central position, a first cutting position, and a second cutting position, wherein the first cutting position and the second cutting position are located on both sides of the central position.

[0077] When the movable cutter 20 moves from the central position to the first cutting position, one of the moving blades 201a of the cutter head 201 holds one of the hanging wire ends 402a of the electromagnetic element 40 against the fixed blade head 101 of one of the two fixed blade seats 10 and cuts it off; when the movable cutter 20 moves from the central position to the second cutting position, the other moving blade 201a of the cutter head 201 holds the other hanging wire end 402a of the electromagnetic element 40 against the fixed blade head 101 of the other of the two fixed blade seats 10 and cuts it off.

[0078] In other words, the drive device 30 can drive the movable cutter 20 to switch between a central position, a first cutting position, and a second cutting position. The central position is where the movable cutter 20 is positioned exactly between the two fixed blade holders 10, with both moving blades 201a separated from the two fixed blade holders 10. When the drive device 30 drives the movable cutter 20 to one side to the first cutting position, one of the moving blades 201a on the movable cutter 20 moves towards the fixed blade holder 10 on the same side (one of the fixed blade holders 10), pressing and cutting off one of the lead wire ends 402a on the electromagnetic element 40 against the fixed blade holder 10. When the drive device 30 drives the movable cutter 20 to the other side to the second cutting position, the other moving blade 201a on the movable cutter 20 moves towards the fixed blade holder 10 on the same side, pressing and cutting off one of the lead wire ends 402a on the electromagnetic element 40 against the fixed blade holder 10 (the other fixed blade holder 10).

[0079] In practical applications, this electromagnetic element wire end cutting device can be mounted on a multi-axis robotic arm. The electromagnetic element 40 is attached in the hanging mechanism. The multi-axis robotic arm can drive the electromagnetic element wire end cutting device to move into the hanging mechanism and lower it to a predetermined height, so that the two fixed blade holders 10 are positioned outside the electromagnetic element 40, that is, the electromagnetic element 40 is better positioned in the workpiece positioning space between the two fixed blade holders 10. At this time, one hanging wire end 402a on the electromagnetic element 40 is exactly between one fixed blade holder 10 and one moving blade 201a of the cutting head 201, and the other hanging wire end 402a on the electromagnetic element 40 is exactly between the other fixed blade holder 10 and the other moving blade 201a of the cutting head 201. Then, the drive device 30 drives the movable cutting blade 20 to move from the central position to the first cutting position and from the central position to the second cutting position, thereby cutting both hanging wire ends 402a at once.

[0080] According to the electromagnetic component wire cutting device provided in the embodiment of the present invention, the movable cutting blade 20 is located between the two fixed blade seats 10 and can switch between a central position, a first cutting position, and a second cutting position. When the movable cutting blade 20 moves from the central position to the first cutting position, one moving blade 201a of the cutting head 201 holds one hanging wire end 402a of the electromagnetic component 40 against the fixed blade head 101 of one of the two fixed blade seats 10 and cuts it off. When the movable cutting blade 20 moves from the central position to the second cutting position, the other moving blade 201a of the cutting head 201 holds the other hanging wire end 402a of the electromagnetic component 40 against the fixed blade head 101 of the other of the two fixed blade seats 10 and cuts it off. In this way, the hanging wire end 402a on the electromagnetic component 40 can be automatically cut off, thereby improving the efficiency of production and processing and the quality of products.

[0081] In some embodiments of the present invention, there are four conductive pins 401a, and each of the four conductive pins 401a forms a hanging wire end 402a. For example, the electromagnetic element 40 has two coils 402, each coil 402 has two wire ends, one at the beginning and one at the end, so the two coils 402 have four wire ends. The insulating base 401 has four conductive pins 401a, and the four wire ends are wound one-to-one around the four conductive pins 401a, thus forming four hanging wire ends 402a. Exemplarily, the four wire ends are arranged symmetrically in pairs and extend along the second direction.

[0082] Each of the fixed blade holders 10 has two fixed blade heads 101, which are arranged opposite each other in a second direction, which is perpendicular to the first direction; the movable cutter member 20 has two cutter heads 201, which are arranged opposite each other in the second direction.

[0083] One of the two cutting heads 201 is located between two opposing fixed cutting heads 101 on the two fixed cutting heads 10, and is used to cut the hanging wire ends 402a on two of the four conductive pins 401a; the other of the two cutting heads 201 is located between two other opposing fixed cutting heads 101 on the two fixed cutting heads 10, and is used to cut the hanging wire ends 402a on the other two of the four conductive pins 401a.

[0084] In other words, the two fixed cutter heads 101 on one fixed cutter holder 10 correspond one-to-one with the two fixed cutter heads 101 on the other fixed cutter holder 10, forming two sets of fixed cutter heads 101. The two fixed cutter heads 101 in each set are arranged opposite to each other in the first direction. The two cutting cutter heads 201 correspond one-to-one with the two sets of fixed cutter heads 101, and each cutting cutter head 201 is located between the two fixed cutter heads 101 in the corresponding set.

[0085] Therefore, when the driving device 30 drives the movable cutter 20 from the central position to the first cutting position, the two moving blades 201a on one side of the two cutter heads 201 respectively cooperate with the fixed blades 101 on the two fixed blade holders 10 on the same side to cut the two hanging wire ends 402a on that side. When the driving device 30 drives the movable cutter 20 from the central position to the second cutting position, the two moving blades 201a on the other side of the two cutter heads 201 respectively cooperate with the fixed blades 101 on the two fixed blade holders 10 on the same side to cut the two hanging wire ends 402a on that side. In this way, four hanging wire ends 402a can be cut quickly, efficiently, and reliably.

[0086] Reference Figures 5 to 8 As shown, in one embodiment of the present invention, the fixed tool head 101 has a stop surface S1a, and the first direction is perpendicular to the stop surface S1a. When the electromagnetic element 40 is located within the workpiece positioning space, the conductive pin 401a is located inside the stop surface S1a and close to the stop surface S1a.

[0087] During the cutting operation, when the cutting head 201 moves towards the fixed blade holder 10, the moving blade 201a on the cutting head 201 applies pressure to the lead wire end 402a. Since the lead wire end 402a is formed by the wire end of the coil 402 wrapped around the conductive pin 401a, it extends outward around the conductive pin 401a. When the moving blade 201a applies pressure to the lead wire end 402a, part of the pressure is transmitted to the conductive pin 401a through the lead wire end 402a. In this embodiment, a stop surface S1a is provided on the fixed blade holder 10. When the stop surface S1a stops outside the conductive pin 401a, it supports the conductive pin 401a, preventing it from deforming outward due to force. This prevents problems such as unsmooth switching of the lead wire end 402a and poor product quality due to deformation of the conductive pin 401a.

[0088] In other words, by using the supporting effect of the stop surface S1a on the conductive pin 401a, it can be ensured that when the moving blade 201a applies pressure to the hanging wire end 402a, the conductive pin 401a will not deform outward, the hanging wire end 402a will smoothly abut against the fixed blade holder 10 and be reliably cut off, thereby improving the reliability of wire cutting and product quality.

[0089] It is understood that the moving blade 201a can cut the hanging wire end 402a by pressing it against the stop surface S1a, or it can cut the hanging wire end 402a by pressing it against other positions of the fixed blade holder 10. This is not intended to limit the present invention.

[0090] Reference Figures 5 to 8 As shown, in one embodiment of the present invention, the fixed cutting head 101 has an inclined surface S1b, which intersects with the stop surface S1a to form a fixed cutting edge 101a, and the moving cutting edge 201a is substantially opposite to the fixed cutting edge 101a in the first direction. Preferably, the included angle between the inclined surface S1b and the stop surface S1a is between 90° and 180°.

[0091] In this embodiment, a fixed cutting edge 101a is formed by the intersection of the inclined plane S1b and the stop surface S1a. When the moving cutting edge 201a approaches the fixed cutting edge 10, the lead wire end 402a abuts against the fixed cutting edge 101a. Under the pressure of the moving cutting edge 201a, a shearing force is easily generated on the fixed cutting edge 101a, making it easier to cut the lead wire end 402a from the position of the fixed cutting edge 101a. In addition, during this process, the lead wire end 402a deflects towards the inclined plane S1b and abuts against the inclined plane S1b, which helps the cut end to form a wrapped and abutting state on the conductive pin 401a after cutting, rather than a loose state deviating from the conductive pin 401a. This wrapped and abutting state helps to improve the reliability of the electrical connection between the coil 402 and the conductive pin 401a, and after spot welding at this position, a more reliable electrical connection can be formed.

[0092] In one embodiment of the present invention, the bottom of the cutting head 201 has a groove H2a for cooperating with the fixed cutting head 101, the groove H2a is open to one side facing the fixed cutting head 101 to form an open side, and the moving cutting edge 201a is formed on the inner wall of the groove H2a.

[0093] In other words, a groove H2a is provided on the cutting head 201. When the movable cutting member 20 moves to the first cutting position, the groove H2a receives the fixed cutting head 101, ensuring that the moving blade 201a can approach the fixed cutting head 101, thereby successfully cutting the leaded wire end 402a. In addition, the groove H2a allows the conductive pin 401a to be inserted, ensuring that the leaded wire end 402a on the conductive pin 401a is located between the fixed cutting head 101 and the moving blade 201a. This ensures accurate and reliable wire cutting.

[0094] Preferably, the bottom of the cutting head 201 is provided with a slit H2b, which communicates with the blade groove H2a and is open in the second direction, so as to avoid the hanging wire end 402a when the electromagnetic element 40 is inserted into the workpiece positioning space. By providing a slit H2b on the cutting head 201 that communicates with the blade groove H2a, when the workpiece positioning space of the electromagnetic element wire end cutting device is positioned and engaged with the electromagnetic element 40, the conductive pin 401a on the electromagnetic element 40 is inserted into the guide groove, and the hanging wire end 402a on the conductive pin 401a can just extend outward from the slit H2b in the second direction, ensuring that the hanging wire end 402a can be positioned between the fixed blade head 101 and the moving blade 201a and extend outward. In this way, it is convenient to cut the hanging wire end 402a and improve the reliability of cutting.

[0095] In one embodiment of the present invention, the fixed tool holder 10 is provided with a positioning groove H1a for positioning the insulating seat 401, and the two fixed tool heads 101 are located on both sides of the positioning groove H1a in the second direction.

[0096] In other words, positioning grooves H1a are provided on the two fixed blade holders 10. These positioning grooves H1a are adapted to the insulating seat 401 of the electromagnetic element 40. When the two fixed blade holders 10 descend, they can ensure that both sides of the insulating seat 401 are locked in the two positioning grooves H1a. In this way, the electromagnetic element 40 is kept fixed. In the subsequent cutting process, based on the relatively stable positional relationship, the hanging wire end 402a can be cut off smoothly.

[0097] Reference Figures 2 to 4 As shown, in one embodiment of the present invention, a base 50 and a swing arm 51 are also included. The base 50 has a downward penetrating swing groove. Exemplarily, the base 50 is a strip structure and the swing groove is formed inside.

[0098] The swing arm 51 passes through the swing groove, and the upper end of the swing arm 51 is pivotable about an axis that extends along the second direction. That is, the swing arm 51 can swing about the axis in the swing groove. The swing amplitude of the swing arm 51 can be limited by the width of the swing groove, thereby defining the first cutting position and the second cutting position of the movable cutter 20.

[0099] Two fixed blade holders 10 are mounted on the lower end of the base 50 and located on both sides of the swing groove in the first direction. The movable cutter 20 is mounted on the lower end of the swing arm 51. The drive device 30 drives the swing arm 51 to swing within the swing groove, so that the movable cutter 20 switches between the central position, the first cutting position, and the second cutting position.

[0100] In other words, the two fixed blade holders 10 are fixed to the bottom of the base 50, while the movable cutter 20 is mounted on the swing arm 51. The drive device 30 is connected to the swing arm 51. The drive device 30 drives the swing arm 51 to swing in the swing groove, thereby driving the movable cutter 20 to switch between the first cutting position, the center position and the second cutting position, thereby cutting the hanging wire end 402a.

[0101] In this embodiment, the swing-type drive structure is adopted. It is stable and the swing is reliable, thereby ensuring that the movable cutter 20 can switch reliably between the first cutting position, the center position and the second cutting position. In addition, the structure is simple, occupies little space and is suitable for cooperation with other mechanisms in the equipment.

[0102] It is understandable that the movable cutter 20 can also adopt a linear drive structure, that is, drive the movable cutter 20 to slide back and forth along a straight line in the first direction, which can also realize the switching between the first cutting position, the center position and the second cutting position.

[0103] Reference Figures 3 to 4 As shown, in one embodiment of the present invention, the driving device 30 includes a first elastic component 301, a second elastic component 302, and a driver. The first elastic component 301 is disposed between the base 50 and one side of the swing arm 51. The second elastic component 302 is disposed between the base 50 and the other side of the swing arm 51. The elastic forces provided by the first elastic component 301 and the second elastic component 302 are in opposite directions, thereby positioning the swing arm 51 in the central position.

[0104] The actuator is mounted on the base 50 and connected to the swing arm 51, for driving the swing arm 51 to move to one side of the first direction against the elastic force of the first elastic component 301, or to move to the other side of the first direction against the elastic force of the second elastic component 302. Exemplarily, the actuator includes a first cylinder 303 and a second cylinder 304, with the first cylinder 303 mounted on one side of the base 50 in the first direction and the second cylinder 304 mounted on the other side of the base 50 in the first direction.

[0105] During the cutting process, the movable cutter 20 can first be driven by the second cylinder 304 to overcome the elastic force of the first elastic component 301 and move to one side in the first direction, thereby cutting off a portion of the lead wire 402a on the electromagnetic element 40. Then, the movable cutter 20 can be driven by the first cylinder 303 to overcome the elastic force of the second elastic component 302 and move to the other side in the first direction, thereby cutting off another portion of the lead wire 402a on the electromagnetic element 40. In this way, the cutting operation of the lead wire 402a can be achieved. In addition, when reset is required, neither the first cylinder 303 nor the second cylinder 304 is working. Under the elastic forces provided by the first elastic component 301 and the second elastic component 302 in opposite directions and of equal magnitude, the movable cutter 20 can be reset to the central position. This drive structure is simple in structure and provides stable and reliable drive.

[0106] An electromagnetic component hanging device according to an embodiment of the present invention includes a hanging mechanism and an electromagnetic component wire cutting device as described in the above embodiment.

[0107] The hanging mechanism is used to assemble the insulating base 401 and the magnetic core and hang the wire end on the magnetic core coil 402 on the conductive pin 401a of the insulating base 401 to form the hanging wire end 402a; the electromagnetic component wire end cutting device is used to cut the hanging wire end 402a.

[0108] According to the embodiment of the present invention, the electromagnetic element 40 hanging device has an electromagnetic element wire cutting device as described above. The movable cutter 20 is located between the two fixed cutter seats 10 and can switch between a central position, a first cutting position, and a second cutting position. When the movable cutter 20 moves from the central position to the first cutting position, one moving blade 201a of the cutter head 201 holds one hanging wire end 402a of the electromagnetic element 40 against the fixed cutter head 101 of one of the two fixed cutter seats 10 and cuts it off. When the movable cutter 20 moves from the central position to the second cutting position, the other moving blade 201a of the cutter head 201 holds the other hanging wire end 402a of the electromagnetic element 40 against the fixed cutter head 101 of the other of the two fixed cutter seats 10 and cuts it off. In this way, the hanging wire end 402a on the electromagnetic element 40 can be automatically cut off, thereby improving the efficiency of production and processing and the quality of products.
