[0031] The polishing apparatus proposed in the embodiments of the application will be further described below with reference to the accompanying drawings.
[0032] Please see Figure 1 , Figure 1 Schematic diagram of the grinding device provided in the embodiment Figure 1 As shown in the figure, the polishing device includes a base 10, a drive mechanism 20, and a polishing component 30. The base 10 is provided with a first limiting groove 11 and a second limiting groove 12 that are connected to each other. The opening direction of the first limiting groove 11 is perpendicular to the opening direction of the second limiting groove 12. The first limiting groove 11 is used to fix the coil area of the coil to be polished, and the second limiting groove 12 is used to fix the wire bending area of the coil to be polished.
[0033] The driving mechanism 20 and the grinding component 30 are both disposed on the base 10. The grinding component 30 is vertically disposed in the first limiting groove 11, and the vertical projection area of the grinding component 30 on the base 10 partially overlaps with the first limiting groove 11. The driving mechanism 20 and the grinding component 30 are connected, and the grinding component 30 rotates under the driving action of the driving mechanism 20.
[0034] The coil to be polished can be a flat inductor coil, specifically a flat coil used in inductors, comprising a coil portion and leads extending from both ends of the coil portion. The coil portion is a flat, wound conductive wire, and both the coil portion and the leads are coated with an insulating sheath. Depending on the direction of the external circuit connection, the leads typically have bending areas in different directions, such as horizontal bending areas and vertical bending areas. Figure 2 As shown, this is a horizontal coil to be polished. Figure 3 for Figure 2 The coil to be polished after bending in the middle, such as Figure 5 As shown, this is the coil to be polished in the vertical direction. Figure 6 Then it is Figure 5 The coil to be polished after being bent in the middle.
[0035] It should be understood that the drive mechanism 20 can be fixedly mounted on the base 10 via a fixing structure, wherein the drive mechanism 20 can be located on one side of the first limiting groove 11 and the second limiting groove 12. The grinding component 30 can also be fixedly mounted on the base 10 via a fixing structure, wherein the grinding component 30 and the drive mechanism 20 are located on the same side of the first limiting groove 11 and the second limiting groove 12, and the grinding component 30 is vertically positioned at the opening of the first limiting groove 11. Under the driving action of the drive mechanism 20, the grinding component 30 is rotated so that it contacts the lead portion of the coil to be ground located in the first limiting groove 11 for grinding. The surface of the grinding component 30 has multiple protrusions of the same grit size. The grinding component 30 rotates under the driving action of the drive mechanism 20 so that the protrusions contact the coil to be ground, thus grinding the area to be ground.
[0036] In an optional embodiment, the coil portion can be fixedly disposed within the first limiting groove 11, and the bent area of the lead portion can be fixedly disposed within the second limiting groove 12. The grinding member 30 rotates under the driving action of the driving mechanism 20 to grind a portion of the exposed lead portion. The area without insulation covering after grinding is the interface for connection with the external circuit.
[0037] In this embodiment, the grinding device can fix the coil area and the bending area of the lead wire of the coil to be ground by the first limiting groove 11 and the second limiting groove 12 respectively, which can improve the accuracy of the lead wire position of the coil.
[0038] It should be understood that, depending on the structure of the base 10, the arrangement of the connected and mutually perpendicular first limiting groove 11 and second limiting groove 12 can be presented in different forms. Because the first limiting groove 11 and second limiting groove 12 presented in different forms can fix coils with different lead-out angles, as shown above, they can include at least the horizontal and vertical directions.
[0039] Please see Figure 1 , Figure 1 Schematic diagram of the grinding device provided in the embodiments of this application Figure 1 As shown in the figure, the base 10 has a square structure. A first limiting groove 11 and a second limiting groove 12 are provided on the base 10. The first limiting groove 11 is located on the first surface of the square structure and extends to the edge of the first surface. The second limiting groove 12 extends from the edge of the first surface to the adjacent second surface. The first limiting groove 11 is used to fix the coil area of the coil to be polished, and the second limiting groove 12 is used to fix the wire bending area of the coil to be polished. At this time, if... Figure 2 As shown, the wire exit angle of the coil to be polished is in the horizontal direction.
[0040] In this way, when the lead angle of the coil to be polished is horizontal, the drive mechanism 20 drives the polishing component 30 to rotate, and the polishing component 30 polishes a portion of the exposed pins. The area without insulation covering after polishing is the interface for connection with the external circuit.
[0041] Optionally, such as Figure 4 As shown, Figure 4 Schematic diagram of the grinding device provided in the embodiments of this application Figure 2 The base 10 includes a first base block and a second base block arranged perpendicularly to each other. The first base block is provided with a first limiting groove 11, and the second base block is provided with a second limiting groove 12.
[0042] As shown in the figure, the base 10 includes a first base block and a second base block that are perpendicular to each other. A first limiting groove 11 is provided on the surface of the first base block, extending towards the second base block. A second limiting groove 12 is provided on the second base block, extending towards the first base block. The two limiting grooves are connected at the junction of the two base blocks. The first limiting groove 11 is used to fix the coil area of the coil to be polished, and the second limiting groove 12 is used to fix the wire bending area of the coil to be polished. At this time, as... Figure 5 As shown, the wire exit angle of the coil to be polished is in the vertical direction.
[0043] Thus, when the lead angle of the coil to be polished is vertical, the drive mechanism 20 drives the polishing component 30 to rotate, and the polishing component 30 polishes a portion of the exposed pins. The area without insulation covering after polishing is the interface for connection with the external circuit.
[0044] Optionally, such as Figure 7As shown, the driving mechanism 20 includes a driving motor, a driving shaft 21, and a connecting belt 22 connected to the driving shaft 21. The grinding component 30 is connected to the connecting belt 22. The driving motor is connected to the driving shaft 21. The driving motor drives the driving shaft 21 to rotate. The connecting belt 22 drives the grinding component 30 to rotate in the direction of the second limiting groove 12.
[0045] In this embodiment, the drive motor is connected to the drive shaft 21, the drive shaft 21 is connected to the connecting belt 22, and the grinding component 30 is connected to the connecting belt 22. The drive motor, drive shaft 21, connecting belt 22, and grinding component 30 are all located on one side of the first limiting groove 11. Simultaneously, the distance between the grinding component 30 and the second limiting groove 12 is less than the distance between the drive motor, drive shaft 21, and connecting belt 22 and the second limiting groove 12. The drive shaft 21 rotates under the drive of the drive motor, thereby moving the connecting belt 22, causing the grinding component 30 to move towards the second limiting groove 12 until it reaches its maximum movable distance. This allows for the grinding of a portion of the exposed pin. The area without insulation covering after grinding becomes the interface for connection to the external circuitry.
[0046] Optionally, the drive mechanism 20 further includes an elastic element 23, the first end of which is connected to the base 10, and the second end of which is connected to the connecting band 22.
[0047] In this embodiment, the two ends of the elastic element 23 are connected to the base 10 and the connecting belt 22, respectively. After the drive shaft 21 rotates for one cycle under the drive of the drive motor, the connecting belt 22 moves away from the second limiting groove 12 under the reset action of the elastic element 23. At this time, the grinding part 30 rotates back to its original position away from the second limiting groove 12. In this way, through N cycles and N reset actions of the elastic element 23, the grinding part 30 continuously contacts the area to be ground, thereby performing grinding, where N is a positive integer greater than 1.
[0048] In an optional embodiment, the elastic element 23 includes a spring structure. When the drive motor drives the drive shaft 21 to rotate and the connecting belt 22 drives the grinding part 30 to move towards the second limiting groove 12 to the maximum movable distance, the spring is at its maximum tension length. Under the spring's reset action, the spring drives the connecting belt 22 to move away from the second limiting groove 12 back to its original position, at which point the spring is at its minimum compression length.
[0049] Optionally, the grinding device further includes a push rod 24, the pusher is vertically disposed in the first limiting groove 11, the push rod 24 is connected to the connecting belt 22, the drive motor drives the drive shaft 21 to rotate, and the connecting belt 22 drives the push rod 24 to rotate in the direction of the second limiting groove 12.
[0050] In this embodiment, the drive motor is connected to the drive shaft 21, the drive shaft 21 is connected to the connecting belt 22, and the push rod 24 is connected to the connecting belt 22. The push rod 24, the drive motor, the drive shaft 21, the connecting belt 22, and the grinding part 30 are all located on one side of the first limiting groove 11. Simultaneously, the distance between the push rod 24 and the grinding part 30 and the second limiting groove 12 is less than the distance between the drive motor, the drive shaft 21, and the connecting belt 22 and the second limiting groove 12. The drive shaft 21 rotates under the drive of the drive motor, thereby moving the connecting belt 22 so that the push rod 24 moves towards the second limiting groove 12 until it reaches its maximum movable distance, thus bending the area of the coil to be bent. The outgoing wire angle of the bent coil matches the conduction direction of the external circuit.
[0051] It should be understood that after the drive shaft 21 rotates for one cycle under the drive of the drive motor, the connecting belt 22 moves away from the second limiting groove 12 under the reset action of the elastic element 23. At this time, the push rod 24 rotates back to its original position away from the second limiting groove 12. In this way, through N cycles and N reset actions of the elastic element 23, the push rod 24 continuously contacts the area to be bent, thereby performing bending.
[0052] In an optional embodiment, after the drive motor drives the drive shaft 21 to rotate and the connecting belt 22 drives the push rod 24 to move to the maximum movable distance in the direction close to the second limiting groove 12, the spring is at its maximum tension length. Under the spring's reset action, the spring drives the connecting belt 22 to move away from the second limiting groove 12 back to its original position, at which point the spring is at its minimum compression length.
[0053] Optionally, the distance between the push rod 24 and the second limiting groove 12 is less than the distance between the grinding part 30 and the second limiting groove 12.
[0054] It should be understood that the push rod 24 and the grinding part 30 are arranged in parallel. The push rod 24 is used to bend the bending area of the coil lead, while the grinding part 30 is used to grind the coil lead area. The coil lead area to be bent is farther away from the coil area than the lead area to be ground.
[0055] In this embodiment, by setting the distance between the push rod 24 and the second limiting groove 12 to be less than the distance between the grinding part 30 and the second limiting groove 12, the push rod 24 and the grinding part 30 can move towards or away from the second limiting groove 12 in the bending area and the grinding area under the driving action of the driving mechanism 20, thereby realizing the completion of the two processes of grinding and bending the coil to be ground.
[0056] In practical implementation, the drive shaft 21 rotates under the drive of the drive motor, causing the connecting belt 22 to move towards the second limiting groove 12. At this time, the push rod 24 and the grinding part 30 also move towards the second limiting groove 12. After the drive shaft 21 rotates for one cycle, under the reset action of the elastic element 23, the connecting belt 22 moves away from the second limiting groove 12. At this time, the push rod 24 and the grinding part 30 rotate back to their original positions away from the second limiting groove 12. In this way, through N cycles and N reset actions of the elastic element 23, the push rod 24 continuously contacts the area to be bent, and the grinding part 30 continuously contacts the area to be ground, thereby performing bending and grinding.
[0057] Optionally, the first limiting groove 11 includes a first sub-groove 111, a second sub-groove 112, and a third sub-groove 113. The second sub-groove 112 and the third sub-groove 113 are both connected to the first sub-groove 111. The second sub-groove 112 and the third sub-groove 113 are arranged in parallel, and the second sub-groove 112 and the third sub-groove 113 both extend from the first sub-groove 111 in a direction away from the first sub-groove 111.
[0058] The grinding component 30 includes a first drive shaft and a first grinder 31 and a second grinder 32 disposed opposite to each other. The first drive shaft is located on the horizontal connecting line between the first sub-slot 111 and the second sub-slot 112. The first grinder 31 is vertically disposed in the first sub-slot 111, and the second grinder 32 is vertically disposed in the second sub-slot 112. The vertical projection area of the first grinder 31 on the base 10 partially overlaps with the first sub-slot 111, and the vertical projection area of the second grinder 32 on the base 10 partially overlaps with the second sub-slot 112.
[0059] Both the first polisher 31 and the second polisher 32 are connected to the first drive shaft, which is connected to the connecting belt 22. The first drive shaft drives the first polisher 31 and the second polisher 32 to rotate.
[0060] It should be understood that the first sub-slot 111, the second sub-slot 112, and the third sub-slot 113 respectively limit the coil area and the two lead-out areas of the coil to be polished. The first sub-slot 111 can be of different shapes depending on the shape of the coil to be polished. Correspondingly, the second limiting slot 12 includes a fourth sub-slot and a fifth sub-slot. The fourth sub-slot is connected to the second sub-slot 112, and the fifth sub-slot is connected to the third sub-slot 113. The fourth sub-slot is used to fix one of the bent lead-out areas, and the fifth sub-slot is used to fix the other bent lead-out area.
[0061] In an optional embodiment, the coil shape of the coil to be polished includes a circle, in which case the first sub-groove 111 is a circular groove.
[0062] In another alternative embodiment, the coil shape of the coil to be polished includes a square shape, in which case the first sub-slot 111 is a square slot.
[0063] The grinding component 30 includes a first drive shaft and two grinding tools arranged opposite each other. The first drive shaft is connected to the connecting belt 22. At this time, the drive motor, drive shaft 21, connecting belt 22 and the second drive shaft can be arranged between the second sub-slot 112 and the third sub-slot 113. The two grinding tools are respectively arranged vertically at the openings of the second sub-slot 112 and the third sub-slot 113. The drive shaft 21 rotates under the drive of the drive motor, which drives the connecting belt 22 to move, and then drives the first drive shaft to rotate, so that the two grinding tools move towards the second limiting groove 12 until the maximum movable distance is reached, so as to grind a part of the exposed pin portion of the two outgoing areas. The area without insulation covering after grinding is the interface for connection with the external circuit.
[0064] In an optional embodiment, the drive motor, drive shaft 21, and connecting belt 22 can be disposed on the outside of the second sub-slot 112 or the third sub-slot 113. The length of the first drive shaft is greater than the maximum vertical distance between the second sub-slot 112 and the third sub-slot 113. The first polisher 31 and the second polisher 32 are both polishing structures disposed on the first drive shaft. The surface of the polishing structure has protrusions with different particle sizes. The polishing part 30 rotates under the driving action of the drive mechanism 20 so that the protrusions contact the coil to be polished and polish the area to be polished. Two grinders are respectively vertically set at the openings of the second sub-slot 112 and the third sub-slot 113. The drive shaft 21 rotates under the drive of the drive motor, which drives the connecting belt 22 to move, and then drives the first transmission shaft to rotate, so that both grinders move towards the second limiting slot 12 until the maximum movable distance is reached, so as to grind a part of the exposed pins of the two outgoing areas. The area without insulation covering after grinding is the interface for connection with the external circuit.
[0065] Optionally, both the first polisher 31 and the second polisher 32 are polishing rollers.
[0066] In this embodiment, both the first polisher 31 and the second polisher 32 are polishing rollers. One end of the polishing roller has multiple protrusions of the same particle size, and the other end has a smooth surface. Thus, under the driving action of the drive motor, the drive shaft 21 is driven to rotate, which drives the connecting belt 22 to move towards the second limiting groove 12. The first transmission shaft connected to the connecting belt 22 rotates, thereby driving the polishing roller with the protrusions to contact the coil to be polished, so as to polish the area to be polished.
[0067] It should be noted that the size of the polishing roller and the polishing precision are related to the required polishing precision of the coil to be polished, and this embodiment does not limit this.
[0068] Optionally, the push rod 24 includes a second drive shaft and a first push rod and a second push rod disposed opposite to each other. The second drive shaft is parallel to the first drive shaft. The first push rod is perpendicular to the first sub-slot 111, and the second push rod is perpendicular to the second sub-slot 112. The vertical projection area of the first push rod on the base 10 partially overlaps with the first sub-slot 111, and the vertical projection area of the second push rod on the base 10 partially overlaps with the second sub-slot 112.
[0069] Both the first push rod and the second push rod are connected to the second drive shaft, which is connected to the connecting belt 22. The second drive shaft drives the first push rod and the second push rod to rotate.
[0070] Two push rods 24 are positioned opposite each other on both sides of the second drive shaft, which is connected to the connecting belt 22. At this time, the drive motor, drive shaft 21, connecting belt 22, and second drive shaft can be positioned between the second sub-slot 112 and the third sub-slot 113. The two push rods 24 are respectively vertically positioned at the openings of the second sub-slot 112 and the third sub-slot 113. The drive shaft 21 rotates under the drive of the drive motor, which drives the connecting belt 22 to move, thereby driving the second drive shaft to rotate, so that both push rods 24 move towards the second limiting groove 12 until the maximum movable distance is reached, so as to bend the two bending areas to match the conduction direction of the external circuit.
[0071] In an optional embodiment, the drive motor, drive shaft 21, and connecting belt 22 can be disposed on the outside of the second sub-slot 112 or the third sub-slot 113. The length of the second drive shaft is greater than the maximum vertical distance between the second sub-slot 112 and the third sub-slot 113. The first and second push rods are both push structures disposed on the second drive shaft, wherein the maximum diameter of the push structure is greater than the diameter of the second drive shaft. The push rod 24 rotates under the drive of the drive mechanism 20 to make the push structure contact the coil to be polished and bend the area to be bent. The two push rods 24 are respectively vertically disposed at the openings of the second sub-slot 112 and the third sub-slot 113. The drive shaft 21 rotates under the drive of the drive motor, driving the connecting belt 22 to move, which in turn drives the second drive shaft to rotate, so that both push rods 24 move toward the direction closer to the second limiting groove 12 until the maximum movable distance is reached, so as to bend the area to be bent on the two outgoing areas to adapt it to the conduction direction of the external circuit.
