Description

Technical Field

[0001] This utility model relates to the field of electromagnetic component processing technology, specifically to a tangent hanging device for electromagnetic components. 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 wire ends of the magnetic core coil 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 wire end at both ends. In the manufacturing of a common-mode inductor, two coils are first wound on the magnetic core, and then the four wire ends of the two coils are wound onto the four conductive pins of the insulating base (this process is called "pin hanging"). During the pin hanging process, after the wire ends are wound onto the conductive pins, the excess wire ends need to be cut off to facilitate subsequent processes.

[0003] The existing wire cutting and lead hanging processes still have some shortcomings and need to be improved for some practical functions. For example, most of the existing wire cutting processes are performed manually, which is inefficient, and the quality of the wire cutting process is affected by human factors to a certain extent, making it impossible to guarantee the quality of the wire cutting, which in turn affects the performance of the processed electromagnetic components. In addition, some wire cutting and lead hanging processes are performed by multiple machines, some of which can only perform the lead hanging process, while others can only perform the wire cutting process. The number of machines used is too large and their structure is relatively complex, resulting in high energy consumption during the process and relatively high maintenance costs. Utility Model Content

[0004] To address the problems mentioned above, the present invention aims to provide a wire-cutting and hanging device for electromagnetic components. This device utilizes a rotating cutter bar assembly, a drive assembly, and an auxiliary base block to replace the traditional manual wire-cutting process, thus resolving the issues of low efficiency and poor quality caused by human error. Furthermore, by reducing the number of machines required for the wire-cutting and hanging processes, and combining this with the simple design of the rotating cutter bar assembly, drive assembly, and auxiliary base block, the invention solves the problems of high energy consumption and high maintenance costs in existing wire-cutting and hanging processes.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A rotary cutter assembly, one end of which is provided with a cutting head, and an eccentric position of the cutting head is provided with a through hole, and the conductive pin is inserted into the interior of the through hole;

[0008] The drive assembly has another end connected to the drive assembly for transmission, and the drive assembly is used to drive the rotary tool holder assembly to rotate on a fixed axis.

[0009] The auxiliary base block includes a receiving groove and a blocking block. The cutting head is movably disposed inside the receiving groove. The cutting head and the blocking block are disposed opposite each other. The driving component drives the rotating blade assembly to make the cutting head rotate on a fixed axis inside the receiving groove. Through the cooperation of the cutting head and the blocking block, the coil wire end is cut and hooked on the conductive pin.

[0010] Furthermore, the rotary cutter assembly includes a first rotary cutter and a second rotary cutter. One end of the first rotary cutter and the second rotary cutter are each provided with a cutting head, and the other end of the first rotary cutter and the second rotary cutter are both connected to the drive assembly for transmission. The first rotary cutter and the second rotary cutter are arranged perpendicularly to each other.

[0011] Furthermore, the driving assembly includes a first driving assembly and a second driving assembly, with the first driving assembly disposed above the second driving assembly, and the first driving assembly and the second driving assembly respectively connected to the first rotating tool bar and the second rotating tool bar of the rotating tool bar assembly.

[0012] Furthermore, the first drive assembly includes a first placement plate, a first cylinder, a first connecting block, and a first connecting member. The first cylinder is fixedly disposed on the left side of the first placement plate. The piston rod of the first cylinder is fixedly connected to one end of the first connecting block. The first connecting block is movably disposed on the first placement plate. The first connecting block has a first connecting groove. One end of the first connecting member is movably engaged inside the first connecting groove. The other end of the first connecting member is connected to the first rotating tool holder drive.

[0013] Furthermore, the second drive assembly includes a second placement plate, a second cylinder, a second connecting block, and a second connecting member. The second cylinder is fixedly disposed on the right side of the second placement plate. The piston rod of the second cylinder is fixedly connected to one end of the second connecting block. The second connecting block is movably disposed on the second placement plate. The second connecting block has a second connecting groove. One end of the second connecting member is movably engaged inside the second connecting groove. The other end of the second connecting member is connected to the second rotating tool holder drive.

[0014] Furthermore, the tangent hanging device also includes an upper cover plate and an intermediate connector. The upper cover plate is fixedly installed on the top of the drive assembly. One end of the intermediate connector is fixedly connected to the bottom of the drive assembly, and the other end of the intermediate connector is fixedly connected to the top of the auxiliary base block. The rotating blade assembly passes through the interior of the intermediate connector.

[0015] Furthermore, the first placement plate is provided with a first placement groove, and the first connecting block is movably placed inside the first placement groove.

[0017] The beneficial effects of this utility model are as follows:

[0018] (1) The wire cutting and hanging device of this utility model includes a rotating blade assembly, a drive assembly and an auxiliary base block. One end of the rotating blade assembly is provided with a cutting head. The auxiliary base block includes a receiving groove and a blocking block. The drive assembly can drive the cutting head at one end of the rotating blade assembly to rotate on a fixed axis inside the receiving groove of the auxiliary base block. The wire cutting process of the coil wire end on the conductive pin is realized by the fixed axis rotation of the cutting head inside the receiving groove and the cooperation of the blocking block. After the wire cutting process is completed, the wire hanging process of the coil wire end on the conductive pin is realized by the fixed axis rotation of the cutting head inside the receiving groove. The wire cutting process and the hanging process of the coil wire end on the conductive pin are realized simultaneously. This replaces the traditional manual wire cutting method, effectively improves the wire cutting efficiency and quality, and eliminates the adverse effects of human factors on the wire cutting process. In addition, the simple structural combination design of the rotating blade assembly, drive assembly and auxiliary base block reduces the number of machines required for the wire cutting process and the hanging process, reduces the energy consumption required for the wire cutting process and the hanging process to a certain extent, and reduces the cost of equipment maintenance.

[0019] (2) The cutting head of this utility model has a through hole at the eccentric position, and the conductive pin is inserted into the through hole. By opening a through hole at the eccentric position of the cutting head instead of the traditional method of opening a through hole at the center position of the cutting head, it can effectively avoid the excessive length of the coil wire end cut by the cutting head during the wire cutting process. This avoids the situation where a long coil wire end remains after the coil wire end is attached to the conductive pin, thereby effectively improving the quality of the attachment process and ensuring the performance of the electromagnetic component after processing.

[0035] Specifically, an external robotic arm is used to vertically move the entire tangent hanging device up and down, thereby adjusting the distance between the tangent hanging device and the electromagnetic component, so as to facilitate the tangent hanging device to perform the tangling and hanging processes on the electromagnetic component.

[0036] The rotary cutter assembly 5 of this utility model includes a first rotary cutter 502 and a second rotary cutter 503. One end of the first rotary cutter 502 and the second rotary cutter 503 is provided with a cutting head 501. The other end of the first rotary cutter 502 and the second rotary cutter 503 are connected to the drive assembly 6 for transmission. The first rotary cutter 502 and the second rotary cutter 503 are arranged perpendicularly and alternately to each other.

[0037] In a specific implementation of this utility model, by arranging the first rotating tool bar 502 and the second rotating tool bar 503 perpendicularly and alternately, and by arranging the first driving component 601 and the second driving component 602 in upper and lower layers, it is possible to effectively prevent operational interference, thereby ensuring the normal operation of the components.

[0038] The drive assembly 6 of this utility model includes a first drive assembly 601 and a second drive assembly 602. The first drive assembly 601 is disposed above the second drive assembly 602. The first drive assembly 601 and the second drive assembly 602 are respectively connected to the first rotating tool bar 502 and the second rotating tool bar 503 of the rotating tool bar assembly 5 for transmission.

[0039] The first drive assembly 601 of this utility model includes a first placement plate 6011, a first cylinder 6012, a first connecting block 6013, and a first connecting member 6014. The first cylinder 6012 is fixedly disposed on the left side of the first placement plate 6011. The piston rod of the first cylinder 6012 is fixedly connected to one end of the first connecting block 6013. The first connecting block 6013 is movably disposed on the first placement plate 6011. The first connecting block 6013 has a first connecting groove 8. One end of the first connecting member 6014 is movably engaged inside the first connecting groove 8.

[0040] The second drive assembly 602 of this utility model includes a second placement plate 6021, a second cylinder 6022, a second connecting block 6023, and a second connecting member 6024. The second cylinder 6022 is fixedly disposed on the right side of the second placement plate 6021. The piston rod of the second cylinder 6022 is fixedly connected to one end of the second connecting block 6023. The second connecting block 6023 is movably disposed on the second placement plate 6021. The second connecting block 6023 has a second connecting groove 9. One end of the second connecting member 6024 is movably engaged inside the second connecting groove 9. The other end of the second connecting member 6024 is connected to the second rotating cutter bar 503 for transmission.

[0041] The tangent hanging device of this utility model also includes an upper cover plate 10 and an intermediate connector 11. The upper cover plate 10 is fixedly covered on the top of the drive assembly 6. One end of the intermediate connector 11 is fixedly connected to the bottom end of the drive assembly 6, and the other end of the intermediate connector 11 is fixedly connected to the top of the auxiliary base block 7. The rotating blade assembly 5 passes through the interior of the intermediate connector 11.

[0042] Specifically, the upper cover plate 10 and the intermediate connecting piece 11 allow the rotary tool holder assembly 5 and the drive assembly 6 to be in a relatively sealed environment to prevent external factors from interfering with them, thereby ensuring the normal operation of both.

[0043] The first placement plate 6011 of this utility model is provided with a first placement groove 12, and the first connecting block 6013 is movably placed inside the first placement groove 12.

[0044] The second placement plate 6021 of this utility model is provided with a second placement groove 13, and the second connecting block 6023 is movably placed inside the second placement groove 13.

[0045] Reference Appendix Figure 1-9 The working process of the tangential hanging device for an electromagnetic component according to this utility model is as follows:

[0046] During operation, the entire wire-cutting hanging device is vertically moved toward the electromagnetic component under the action of the external robotic arm, so that the conductive pins 4 on the insulating base 2 are inserted into the through holes 5011 on the cutting head 501, and at the same time, the coil wire ends 3 at both ends of the magnetic core coil 1 are inserted between the cutting head 501 and the blocking block 702.

[0047] Secondly, the first cylinder 6012 and the second cylinder 6022 are started simultaneously. The piston rods of the first cylinder 6012 and the second cylinder 6022 push the first connecting block 6013 and the second connecting block 6023 respectively, so that the first connecting block 6013 moves to the right in the first placement groove 12 on the first placement plate 6011 and the second connecting block 6023 moves to the left in the second placement groove 13 on the second placement plate 6021. This allows the first connecting member 6014 and the second connecting member 6024 to rotate a certain angle with the connecting end of the first connecting member 6014 and the first rotating cutter bar 502, and the connecting end of the second connecting member 6024 and the second rotating cutter bar 503 as the central fulcrum. At the same time, one end of the first connecting member 6014 and the second connecting member 6024 moves inside the first connecting groove 8 and the second connecting groove 9 respectively, so that the first rotating cutter bar 502 and the second rotating cutter bar 503 rotate on a fixed axis, thereby realizing the fixed axis rotation of the cutting head 501 inside the receiving groove 701 of the auxiliary base block 7.

[0048] Subsequently, after the cutting head 501 rotates a certain distance on a fixed axis inside the receiving groove 701, it will trap the coil wire end 3 between the cutting head 501 and the side of the blocking block 702. By allowing the cutting head 501 to continue rotating on a fixed axis and combining with the blocking of the side of the blocking block 702, the coil wire end 3 located outside the side of the blocking block 702 is cut off and detached, thus completing the wire cutting process of the coil wire end 3 on the conductive pin 4. After the wire cutting process is completed, the cutting head 501 continues to rotate on a fixed axis. One side of the cutting head 501 rotates on a fixed axis with the remaining coil wire end 3, so that the remaining coil wire end 3 is wound around the conductive pin 4, thus completing the hanging process of the coil wire end 3 on the conductive pin 4.

[0049] After completing the cutting and hanging processes on conductive pin 4, the cutting and hanging device is reset as a whole under the action of an external robotic arm, and the electromagnetic component can proceed to the next process.

[0050] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
