Description

Technical Field

[0001] The utility model relates to the technical field of inductor assembly, in particular to a tangent mechanism used for inductor assembly. Background Art

[0002] Inductors are commonly used electrical components. In order to convert electrical energy into magnetic energy and store it, a wire needs to be wound around the magnetic core of the inductor to form a coil. In order to improve the production efficiency of inductors, automated equipment is generally used to assemble inductors. The automated equipment is provided with a core winding mechanism and a wire cutting mechanism. When winding, the core is first clamped and fixed by the core winding mechanism, and then the wire is fed to the core by the wire feeding mechanism, and then the core is driven to rotate in cooperation with the core winding mechanism to complete the winding. After winding, the wire is cut by the wire cutting mechanism to facilitate subsequent welding processes. The current wire cutting mechanism includes a power device and a wire cutting knife connected to the power device. When cutting, the wire is in a suspended state, and the wire cutting knife contacts the wire. Due to the lack of support and fixation, the wire is pressed and offset, and the actual cutting position of the wire is inconsistent with the preset cutting position. The cut of the wire is uneven. In order to ensure the quality of the inductor, the cut of the wire needs to be polished and smoothed before the subsequent welding process can be carried out, which reduces the production efficiency of the inductor.

In addition, the technical features involved in each embodiment of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0022] See also Figure 1 and Figure 2 The utility model relates to a wire cutting mechanism for inductor assembly, which comprises a wire cutting base 1 arranged at a winding position of a machine, a movable knife holder arranged on the top of the wire cutting base 1, and a wire cutting knife 2 arranged on the knife holder and capable of cutting a wire; a wire cutting groove 3 is arranged on the top of the wire cutting base 1, and a driving device drives the knife holder and the wire cutting base 1 to close together to clamp the wire, and at the same time drives the wire cutting knife 2 to cooperate with the wire cutting groove 3 arranged on the top of the wire cutting base 1 to cut the clamped wire.

[0023] The knife holder includes a pressing plate 4 opposite to the top of the tangent base 1, and a knife mounting plate 5 located on the top of the pressing plate 4 for mounting the wire cutting knife 2; a guide piece is provided on the pressing plate 4, and the knife mounting plate 5 is connected to the guide piece and can move along the guide piece to realize that the knife mounting plate 5 and the pressing plate 4 are moving away from or close to each other; a driving device is connected to the knife mounting plate 5, and the driving device can apply a driving force to the knife mounting plate 5. After receiving the driving force, the knife mounting plate 5 moves along the guide piece toward the pressing plate 4, and accordingly drives the pressing plate 4 to close with the tangent base 1 to clamp the wire. After closing, the knife mounting plate 5 continues to move, driving the wire cutting knife 2 to pass through the bottom of the pressing plate 4 and cooperate with the wire cutting groove 3 set on the top of the tangent base 1 to complete the wire cutting.

[0024] Specifically, the pressing plate 4 and the knife-mounting plate 5 are both rectangular plate structures; in this embodiment, the driving device is a cylinder 6, the piston rod of the cylinder 6 is connected to the top surface of the knife-mounting plate 5, and the wire cutter 2 is fixedly installed at the center of the bottom surface of the knife-mounting plate 5. A knife hole for the wire cutter 2 to pass through is provided at the center of the pressing plate 4, and the knife hole passes through the top and bottom surfaces of the pressing plate 4, and the wire cutter 2 can move in the knife hole of the pressing plate 4; when cutting wire, the knife head 2b of the wire cutter 2 extends out of the knife hole; when not cutting wire, the knife head 2b of the wire cutter 2 retracts into the knife hole to avoid the knife head 2b of the wire cutter 2 being exposed for a long time to adhere to dust or collide, thereby extending the service life of the wire cutter 2.

[0025] The guide member is a guide column 7, one end of which is connected to the top surface of the pressure plate 4, and the other end of the guide column 7 passes through the top surface of the knife mounting plate 5 and is provided with a stop cap to prevent the guide column 7 and the knife mounting plate 5 from detaching from each other; a guide hole for the guide column 7 to pass through is opened on the knife mounting plate 5, and the guide hole passes through the top and bottom surfaces of the knife mounting plate 5.

[0026] During the specific implementation, the cylinder 6 is started, and the piston rod of the cylinder 6 extends to generate thrust, pushing the knife plate 5 to move toward the pressing plate 4. An elastic member is connected between the knife plate 5 and the pressing plate 4, and the pressing plate 4 is driven by the elastic member to move toward the tangent base 1; when the pressing plate 4 and the tangent base 1 are closed together to clamp the wire, the knife plate 5 continues to move toward the pressing plate 4, and the distance between the knife plate 5 and the pressing plate 4 is reduced. The elastic member is compressed to generate elastic force, so that the pressing plate 4 remains closed with the tangent base 1, and the knife plate 5 continues to move toward the pressing plate 4. The knife plate 5 drives the wire cutting knife 2 to move along the knife hole on the pressing plate 4, and moves to extend out of the bottom surface of the pressing plate 4 to cooperate with the wire cutting groove 3 set on the top of the wire cutting base 1 to complete the cutting of the wire; the non-cutting part of the wire is clamped and fixed by the pressing plate 4 and the wire cutting base, so that the wire as a whole is maintained in a straight state, and the cutting part of the wire is subjected to greater force when it contacts the wire cutting knife 2, so that the wire can be quickly cut off, and the incision of the wire remains flat, which is conducive to the subsequent inductor welding process and improves the overall quality of the inductor.

[0027] In the present embodiment, four guide posts 7 are provided, and the four guide posts 7 are respectively located at four right angles of the pressing plate 4. Correspondingly, four guide holes are provided on the knife mounting plate 5. The guide posts 7 correspond to the guide holes one by one to form four guide points, so that the force is more balanced, so that the knife mounting plate 5 and the pressing plate 4 can be guided away from or close to each other more stably, which is conducive to driving the wire cutting knife 2 to accurately cut at the cutting position of the wire, avoiding deviation and uneven incision of the wire.

[0028] When the wire is cut, the spring 8 is in a state of extension. When the wire is cut, the knife plate 5 moves toward the direction close to the pressure plate 4, and the spring 8 drives the pressure plate 4 to move toward the direction of the cutting base 1. When the pressure plate 4 and the cutting base 1 are closed together to clamp the wire, the guide column 7 and the guide hole cooperate with each other to guide the knife plate 5 to continue to move toward the pressure plate 4. The distance between the knife plate 5 and the pressure plate 4 is reduced, and the spring 8 is compressed to form an elastic force, so that the pressure plate 4 can keep closing with the cutting base 1. At the same time, the knife plate 5 drives the cutting knife 2 to move along the knife hole on the pressure plate 4, and moves to the bottom surface of the pressure plate 4 and cooperates with the cutting groove 3 set on the top of the cutting base 1 to complete the cutting.

The handle 2a is a rod structure, one end of the handle 2a is threadedly connected to the knife mounting plate 5, and the other end of the handle 2a is threadedly connected to the cutter head 2b; the cutter head 2b is a right-angled triangle structure with a wide top and a sharp bottom, one side of the cutter head 2b is a vertical first cut surface, and the other side of the cutter head 2b is an inclined second cut surface, the bottom of the first cut surface is connected to the bottom of the second cut surface to form an angle, and the angle between the first cut surface and the second cut surface of the cutter head 2b is 35°; the wire cutting groove 3 at the top of the wire cutting base 1 is a right-angled triangle groove body corresponding to the cutter head 2b of the wire cutting knife 2, and the top of the wire cutting groove 3 forms a notch; the pressing plate 4 and the wire cutting base 1 are closed together to clamp When the non-cutting part of the wire is tightened, the cutting part of the wire is suspended at the notch of the wire cutting groove 3. By pushing the knife mounting plate 5 to move toward the pressing plate 4, the wire cutting knife 2 is driven to move along the knife hole on the pressing plate 4, so that the knife head 2b of the wire cutting knife 2 extends out of the bottom surface of the pressing plate 4 and contacts the cutting part of the wire to complete the cutting. After the cutting, the knife head 2b of the wire cutting knife 2 cooperates with the wire cutting groove 3. The knife head 2b of the wire cutting knife 2 in this embodiment can further improve the flatness of the wire incision, and avoid the wire head from curling up and affecting the subsequent welding process. At the same time, the knife handle 2a and the knife head 2b are threadedly connected, which can be quickly disassembled and assembled. After the knife head 2b is worn, there is no need to replace the wire cutting knife 2 as a whole, which is beneficial to reducing production costs.
