Description

Technical Field

[0001] This utility model relates to the technical field of amorphous ribbon production equipment, specifically to an auxiliary winding and welding mechanism and an automatic winding device for amorphous ribbon magnetic cores equipped with the auxiliary winding and welding mechanism. Background Technology

[0002] Amorphous alloy materials possess excellent physical properties such as high efficiency, low loss, and high magnetic permeability, which has promoted the development of electronic components towards high frequency, high efficiency, energy saving, and miniaturization, and enabled them to partially replace traditional materials such as silicon steel and permalloy. Especially in power technology, three-dimensional magnetic core distribution transformers made by winding amorphous alloy strips have the characteristics of high strength, three-phase balance, uniform temperature rise, short circuit resistance, low noise, material saving, and low leakage flux. This results in a significant reduction in seamless connection air gap, a substantial reduction in magnetic reluctance, and a significant reduction in no-load current, making it a major development direction for the transformer industry towards green environmental protection and energy saving.

[0003] An automatic winding equipment for amorphous strip magnetic cores is a device used to wind amorphous alloy strips into three-dimensional magnetic cores, such as... Figure 1 As shown, it includes a feeding mechanism 91, a winding mechanism 92, a cutting mechanism 93, an auxiliary winding and welding mechanism 94, and a welding mechanism 95. The feeding mechanism 91 is used to transfer the unwound amorphous alloy strip onto the winding needle of the winding mechanism 92; the winding mechanism 92 is used to wind the amorphous alloy strip to form a magnetic core; the cutting mechanism 93 is used to cut the wound amorphous alloy strip to a fixed length. Figure 2 As shown, the auxiliary winding and welding mechanism 94 includes a first driving unit 941 and a clamping assembly 942. The first driving unit 941 drives the clamping assembly 942 to move relative to the magnetic core in the axial direction of the winding needle. After the cutting mechanism 93 completes the cutting action, the first driving unit 941 drives the clamping assembly 942 to first shape the end of the magnetic core shaft, and then drives the clamping assembly 942 to press it onto the magnetic core. The auxiliary winding mechanism 92 performs finishing treatment on the end of the amorphous alloy strip of the magnetic core, and the auxiliary welding mechanism 95 performs welding treatment on the outer periphery of the magnetic core. After the winding and outer periphery welding treatment of the magnetic core are completed, the first driving unit 941 drives the clamping assembly 942 to release the clamping and fixing of the magnetic core, so as to facilitate the unloading of the magnetic core.

[0004] However, the existing auxiliary winding and welding mechanism 94 has the following defects: During the process of the clamping component 942 clamping the magnetic core and the auxiliary winding mechanism 92 driving the magnetic core to rotate, the magnetic core is subjected to a certain clamping force by the clamping component 942, and the magnetic core rotates relative to the clamping component 942, which causes friction between the clamped end of the magnetic core and the clamping component 942, which can easily lead to wear at the end of the magnetic core and affect product quality; Secondly, the unbalanced force at both ends of the magnetic core during the finishing winding process causes the magnetic core to be twisted to a certain extent, which makes it very easy for wrinkles and winding position to occur during the finishing process of the amorphous alloy strip, affecting the finishing quality of the amorphous alloy strip. Summary of the Invention

[0005] To address the aforementioned problems, the main objective of this invention is to provide an auxiliary winding and welding mechanism that can improve the quality of magnetic core winding and welding.

[0006] Another objective of this invention is to provide an automatic winding device for amorphous strip magnetic cores equipped with the aforementioned auxiliary winding and welding mechanism.

[0007] To achieve the main objective of this utility model, this utility model provides an auxiliary winding and welding mechanism, including a clamping unit. The clamping unit includes a clamping component and a first driving module. The first driving module can drive the clamping component to move in a first direction. The clamping unit also includes a second driving module. The clamping component is rotatably connected to the driving end of the first driving module around its own first axis. The second driving module can drive the clamping component to rotate. The first axis is parallel to the first direction.

[0008] As can be seen from the above, by adding a second drive module to drive the second clamping assembly, the clamping assembly can rotate with the drive end of the winding mechanism when it is used in conjunction with the winding mechanism of the automatic winding equipment for amorphous strip magnetic core to finish the end of the amorphous alloy strip of the magnetic core and when it is used in conjunction with the welding mechanism to weld the outer periphery of the magnetic core. This avoids friction between the clamping assembly and the end of the magnetic core, prevents wear on the end of the magnetic core, and balances the forces on both ends of the magnetic core during the finishing winding process. This prevents the magnetic core from being twisted and prevents problems such as wrinkles and winding position displacement during the finishing process of the amorphous alloy strip end, thus ensuring the finishing quality of the amorphous alloy strip end and the welding quality of the outer periphery of the magnetic core.

[0009] In a preferred embodiment, the second drive module includes a fixed base, a first motor, a flexible transmission assembly, a support base, a transmission rod, a connecting rod, and a first transmission wheel set. The first motor is mounted on the fixed base, the input wheel of the flexible transmission assembly is connected to the drive shaft of the first motor, the support base is mounted on the fixed base, the transmission rod can rotate relative to the support base around its second axis, and the transmission rod can slide relative to the support base and the output wheel of the flexible transmission assembly in a first direction. The output wheel can drive the transmission rod to rotate. The second axis is parallel to the first direction. The connecting rod connects the drive end of the first drive module and the transmission rod, and the first drive module can drive the transmission rod to slide via the connecting rod. The first transmission wheel set connects the transmission rod and the clamping assembly, and the transmission rod can drive the clamping assembly to rotate via the first transmission wheel set.

[0010] As can be seen from the above, this design allows the drive end of the first drive module to only drive the clamping assembly, transmission rod, connecting rod and first transmission wheel set to slide, without having to drive the entire second drive module. This effectively reduces the load on the first drive module and also reduces the space that the automatic winding equipment for amorphous strip magnetic cores needs to provide for the second drive module. This helps to optimize the layout between the various mechanisms of the automatic winding equipment for amorphous strip magnetic cores and reduce the size of the automatic winding equipment for amorphous strip magnetic cores.

[0011] A further embodiment is that the first transmission wheel assembly includes a first driving wheel and a first driven wheel. The first driving wheel is mounted on the transmission rod and can move with the transmission rod in a first direction. The first driven wheel is mounted on the clamping assembly. Both the first driving wheel and the first driven wheel are gears, or both the first driving wheel and the first driven wheel are friction wheels. The flexible transmission assembly is a belt transmission assembly or a chain transmission assembly.

[0012] As can be seen from the above, the design can ensure the stability and reliability of the second drive module driving the clamping component to rotate, and guarantee the transmission efficiency of the first transmission wheel set, flexible transmission component, etc.

[0013] A further proposed solution is that the second drive module also includes a bushing and a rolling bearing. The bushing is rotatably mounted in the support seat, and the transmission rod is slidably connected to the bushing in the first direction and can drive the bushing to rotate. The rolling bearing is located between the bushing and the support seat.

[0014] As can be seen from the above, the bushing helps the first drive module to drive the transmission rod to slide more smoothly, and the rolling bearing helps the first motor to drive the transmission rod and the clamping assembly to rotate more smoothly.

[0015] Another preferred embodiment is that the second drive module includes a mounting base, a second motor, and a transmission assembly. The drive end of the first drive module can also drive the mounting base to move in a first direction. The second motor is mounted on the mounting base, and the transmission assembly is connected between the drive shaft of the second motor and the clamping assembly. The second motor can drive the clamping assembly to rotate through the transmission assembly.

[0016] As can be seen from the above, this design can simplify the structure of the second drive module and improve the efficiency of the second drive module in driving the clamping component to rotate.

[0017] Another preferred embodiment is that the clamping assembly includes a base, a clamping member, and an elastic member. The base is rotatably connected to the drive end of the first drive module about a first axis. The clamping member is slidably connected to the base in a first direction. The elastic member is connected between the base and the clamping member and forces the clamping member to move away from the first drive module.

[0018] As can be seen from the above, this design can avoid hard compression between the clamping component and the magnetic core, prevent the magnetic core from being damaged by pressure, and at the same time ensure the clamping effect of the clamping component on the magnetic core and the relative stillness between the clamping component and the magnetic core.

[0019] A further option is to have a rubber or silicone part on the clamping part.

[0020] As can be seen from the above, this design can prevent the clamping parts from damaging the magnetic core.

[0021] A further embodiment of the auxiliary winding and welding mechanism includes a winding limiting unit, a sliding module, and a driving unit. The winding limiting unit includes a limiting rod assembly and a third driving module. The limiting rod assembly includes a limiting rod and a connecting seat. The limiting rod is parallel to the first direction and is mounted on the connecting seat. The third driving module can drive the connecting seat to move in the first direction. The sliding module includes a slide rail and a sliding seat. The slide rail extends along the second direction and the sliding seat is slidably connected to the slide rail. The pressing unit and the winding limiting unit are mounted on the sliding seat. The second direction is perpendicular to the first direction. The driving unit can drive the sliding seat to slide along the slide rail.

[0022] As can be seen from the above, the winding limiting unit is used to limit the amorphous alloy strip during the magnetic core winding process, so that the amorphous alloy strip can be better wound into a magnetic core; the driving unit and sliding module are used to control the winding limiting unit to move out of the current position after the unwound amorphous alloy strip is cut to a fixed length, and simultaneously control the pressing unit to move to the magnetic core to shape and press the magnetic core, so as to assist in the finishing and welding of the amorphous alloy strip of the magnetic core.

[0023] A further embodiment is that the auxiliary winding welding mechanism also includes a welding unit. In the second direction, the welding unit and the winding limiting unit are located on both sides of the first drive module. The welding unit includes a welding head assembly and a fourth drive module. The fourth drive module is mounted on a sliding seat and can drive the welding head assembly to move in the first direction.

[0024] As can be seen from the above, the welding unit is used to weld the inside of the wound magnetic core. By mounting the welding unit on the sliding seat, the clamping unit, winding limiting unit and welding unit can be driven to move simultaneously by a single drive unit, thereby simplifying the structure of the auxiliary winding and welding mechanism, reducing the number of drive sources to optimize the drive and reduce costs.

[0025] To achieve another objective of this utility model, this utility model provides an automatic winding device for amorphous strip magnetic cores, which includes the aforementioned auxiliary winding and welding mechanism.

[0026] As can be seen from the above, by setting up the above-mentioned auxiliary winding and welding mechanism, the magnetic cores processed by the automatic winding equipment for amorphous strip magnetic cores have higher forming accuracy and better quality, thereby reducing the defect rate of the magnetic cores processed by the automatic winding equipment for amorphous strip magnetic cores.

[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0033] First embodiment of auxiliary winding and welding mechanism

[0034] Reference Figure 3 and Figure 4 The auxiliary winding and welding mechanism 100 includes a clamping unit 1, a winding and limiting unit 2, a sliding module 3, a welding unit 4, and a driving unit 5.

[0035] Combination Figure 5 The clamping unit 1 includes a clamping assembly 11, a first drive module 12, a second drive module 13, a support seat 134, a transmission rod 135, a connecting rod 136, a first transmission wheel set 137, a bushing 138, and a rolling bearing 139.

[0036] The clamping assembly 11 is used to clamp the wound magnetic core in conjunction with the winding mechanism of the automatic winding equipment for amorphous strip magnetic cores, so as to assist the winding mechanism in finishing the end of the amorphous alloy strip of the magnetic core; in addition, the clamping mechanism is also used to weld the outer periphery of the wound magnetic core in conjunction with the winding mechanism and the welding mechanism of the automatic winding equipment for amorphous strip magnetic cores.

[0037] Preferably, the clamping assembly 11 includes a base 111, a clamping member 112, and an elastic member 113. The base 111 is rotatably mounted on the drive end of the first drive module 12 about its own first axis, so that the first drive module 12 can drive the clamping assembly 11 to move in a first direction (parallel to the axial direction of the winding needle of the winding mechanism), so that the clamping assembly 11 cooperates with the winding mechanism to clamp or release the magnetic core; wherein, the first axis is parallel to the first direction. In this embodiment, the first drive module 12 is a cylinder; of course, in some embodiments, the first drive module 12 may be an electric cylinder or other drive modules with the same function.

[0038] The clamping member 112 is slidably connected to the base 111 in the first direction, so that the clamping member 112 can slide relative to the base 111 in the first direction. Preferably, the clamping member 112 is provided with a rubber part or a silicone part; the rubber part or silicone part is used to contact the end of the magnetic core, so as to avoid hard contact between the clamping member 112 and the magnetic core, thereby avoiding damage to the magnetic core during the clamping process.

[0039] The elastic element 113 is installed inside the base 111 and connected between the base 111 and the clamping element 112. The elastic element 113 is used to force the clamping element 112 to move away from the drive end of the first drive module 12 in a first direction; wherein, the elastic element 113 is preferably a compression spring. The clamping element 112 is slidably connected to the base 111. With the action of the elastic element 113, it can further avoid the clamping assembly 11 from hard squeezing the magnetic core and prevent the magnetic core from being damaged by pressure. In addition, under the action of the elastic element 113, it can also ensure that the clamping element 112 reliably presses the magnetic core onto the winding mechanism, ensuring the clamping effect on the magnetic core, and ensuring that the magnetic core and the clamping assembly 11 can remain relatively stationary, so as to reduce the magnetic core being twisted during the finishing process of the amorphous alloy strip end and / or the welding mechanism welding the magnetic core.

[0040] The second drive module 13 is used to drive the clamping assembly 11 to rotate relative to the drive end of the first drive module 12. This allows the clamping assembly 11 to rotate synchronously with the winding needle of the winding mechanism during the finishing process of the amorphous alloy strip of the magnetic core by the auxiliary winding mechanism and the welding process of the winding and welding mechanisms on the outer periphery of the magnetic core. This prevents the clamping assembly 11 from rubbing against the end of the magnetic core and avoids wear on the end of the magnetic core. In addition, the synchronous rotation of the clamping assembly 11 and the winding needle of the winding mechanism can balance the forces at both ends of the magnetic core, preventing the magnetic core from being twisted and deformed. This prevents problems such as wrinkles and misalignment of the winding position during the finishing process of the amorphous alloy strip, ensuring the finishing quality of the amorphous alloy strip and the welding quality of the outer periphery of the magnetic core, and improving the forming accuracy and quality of the magnetic core.

[0041] In this embodiment, the second drive module 13 includes a fixed base 131, a first motor 132, a flexible transmission assembly 133, a support base 134, a transmission rod 135, a connecting rod 136, a first transmission wheel set 137, a bushing 138, and a rolling bearing 139. The fixed base 131 is fixedly connected to the cylinder of the first drive module 12; alternatively, the fixed base 131 can also be fixedly connected to the frame of an automatic winding equipment for amorphous strip magnetic cores.

[0042] The first motor 132 and the bearing housing are both mounted on the fixed base 131. The transmission rod 135 can rotate relative to the bearing housing in the first direction, and the transmission rod 135 can rotate relative to the support base 134 around its own second axis. The flexible transmission assembly 133 is connected between the drive shaft of the first motor 132 and the transmission rod 135, so that the first motor 132 can drive the transmission rod 135 to rotate; wherein, the second axis is parallel to the first direction.

[0043] In this embodiment, the flexible transmission assembly 133 is a belt transmission assembly. The input wheel 1331 of the belt transmission assembly is fixedly connected to the drive shaft of the first motor 132, and the output wheel 1332 of the belt transmission assembly is keyed to the transmission rod 135. The output wheel 1332 is rotatably mounted on the fixed base 131 around its own axis, allowing the transmission rod 135 to slide relative to the output wheel 1332 in a first direction, and the output wheel 1332 can drive the transmission rod 135 to rotate. Preferably, both the input wheel 1331 and the output wheel 1332 are synchronous pulleys. Correspondingly, the belt 1333 connecting the input wheel 1331 and the output wheel 1332 is a synchronous belt, to prevent slippage between the belt 1333 and the input wheel 1331 or the output wheel 1332 when the first motor 132 drives the output wheel 1332 and the transmission rod 135 to rotate via the flexible transmission assembly 133, thus ensuring the reliability of the flexible transmission assembly 133's transmission. Of course, in other embodiments, the flexible transmission component 133 can also be a chain transmission component. Since the assembly method of the chain transmission component is basically the same as that of the belt transmission component, it will not be described in detail here.

[0044] The connecting rod 136 is fixedly connected between the transmission rod 135 and the drive end of the first drive mechanism, so that when the first drive module 12 drives the pressing component 11 to move, the first drive module 12 can drive the transmission component to move synchronously and in the same direction through the connecting rod 136.

[0045] The first transmission wheel set 137 is connected between the transmission rod 135 and the base 111 of the clamping assembly 11, so that the transmission rod 135 can drive the clamping assembly 11 to rotate synchronously through the first transmission wheel set 137. In this embodiment, the first transmission wheel set 137 includes a first driving wheel 1371 and a first driven wheel 1372. Both the first driving wheel 1371 and the first driven wheel 1372 are gears. The first driving wheel 1371 is mounted on the transmission rod 135 and fixedly connected to it, so that the driving wheel 1371 can rotate with the transmission rod 135 and move with it. The first driven wheel 1372 is mounted on the base 111 and fixedly connected to it. The first driven wheel 1372 meshes with the first driving wheel 1371, so that when the transmission rod 135 is driven to rotate by the first motor 132 and the flexible transmission assembly 133, the transmission rod 135 can drive the clamping assembly 11 to rotate synchronously through the first transmission wheel set 137. Of course, in some embodiments, the first driving wheel 1371 and the first driven wheel 1372 may both be friction wheels. Through the design of the first transmission wheel set 137, the stability and reliability of the second drive module 13 driving the clamping assembly 11 to rotate are effectively guaranteed, and the transmission efficiency of the first transmission wheel set 137, the flexible transmission assembly 133, etc. is guaranteed.

[0046] In some embodiments, an idler wheel or idler wheel assembly may be provided between the first driving wheel 1371 and the first driven wheel 1372 as needed. The idler wheel or idler wheel assembly can move synchronously with the first driving wheel 1371, the first driven wheel 1372, the clamping assembly 11, the transmission rod 135, the connecting rod 136, etc. The arrangement of the idler wheel or idler wheel assembly can change the transmission ratio of the first transmission wheel assembly 137, thereby changing the output torque, speed, etc. of the clamping assembly 11.

[0047] By designing the structure of the second drive module 13, when the first drive module 12 drives the pressing assembly 11 to move, the first drive module 12 only needs to drive the transmission rod 135, connecting rod 136 and first transmission wheel set 137 of the second drive module 13 to move, without having to drive the entire second drive module 13 to move, thereby reducing the drive load of the first drive module 12. In addition, since the entire second drive module 13 does not need to move, the clearance space required when the second drive module 13 moves can be reduced, which helps to optimize the layout between the various mechanisms of the automatic winding equipment for amorphous strip magnetic cores and reduce the size of the automatic winding equipment for amorphous strip magnetic cores.

[0048] The bushing 138 is rotatably mounted within the support 134. The bushing 138 is keyed to the transmission rod 135, allowing the transmission rod 135 to slide relative to the bushing 138 in a first direction, and enabling the transmission rod 135 to drive the bushing 138 to rotate. The bushing 138 helps the first drive module 12 to drive the transmission rod 135 to slide more smoothly, thereby reducing the sliding resistance of the transmission rod 135. A rolling bearing 139 is disposed between the bushing 138 and the support 134 to reduce the resistance encountered by the bushing 138 and the rotating rod when rotating relative to the support 134, thereby enabling the first motor 132 to drive the transmission rod 135 and the clamping assembly 11 to rotate more smoothly.

[0049] The winding limiting unit 2 includes a limiting rod assembly 21 and a third drive module 22. The limiting rod assembly 21 includes a limiting rod 211 and a connecting seat 212. The limiting rod 211 is mounted on the connecting seat 212 and is parallel to the first direction. The connecting seat 212 is connected to the drive end of the third drive module 22, so that the third drive module 22 can drive the connecting seat 212 to move in the first direction. The winding limiting unit 2 is used to limit the amorphous alloy strip during the magnetic core winding process, so that the amorphous alloy strip can be better wound into a magnetic core. Preferably, the connecting seat 212 can be rotatably connected to the driving end of the third driving module 22, wherein the rotation axis of the connecting seat 212 is parallel to the first direction, and a reset elastic element is provided between the connecting seat 212 and the driving end of the third driving module 22, so that during the magnetic core winding process, as the radius of the magnetic core increases with the increase of the magnetic core radius of the limiting rod 211, the connecting seat 212 is driven to rotate, so that there is no need to control the movement of the winding limiting unit 2 during this process. The reset elastic element 113 is used to reset the rotation of the rotating seat; in addition, the reset elastic element can also ensure the reliability of the limiting rod 211 in limiting the amorphous alloy strip and avoid the limiting rod 211 from damaging the amorphous alloy strip.

[0050] In this embodiment, the third drive module 22 is a cylinder; of course, in some embodiments, the third drive module 22 may be an electric cylinder or other drive modules with the same function.

[0051] The sliding module 3 has a slide rail 31 and a sliding seat 32. The slide rail 31 extends along a second direction, which is perpendicular to the first direction. The sliding seat 32 is slidably connected to the slide rail 31. The pressing unit 1 and the winding limiting unit 2 are installed on the sliding seat 32.

[0052] The drive unit 5 drives the sliding seat 32 to slide along the slide rail 31. After the unwound amorphous alloy strip is cut to a fixed length, it controls the winding limiting unit 2 to move out of its current position and simultaneously controls the clamping unit 1 to move to the magnetic core to shape and clamp it, thereby assisting in the finishing and welding of the amorphous alloy strip to the magnetic core. In this embodiment, the drive unit 5 is a cylinder; however, in some embodiments, the drive unit 5 may be an electric cylinder or other drive units 5 with the same function.

[0053] In the second direction, the welding unit 4 and the winding limiting unit 2 are located on both sides of the first drive module 12. By setting the relative positions of the pressing unit 1, the winding limiting unit 2 and the welding unit 4, the time required for the pressing unit 1, the winding limiting unit 2 and the welding unit 4 to move to the target position can be reduced, making the structural layout of the auxiliary winding welding mechanism 100 more reasonable and helping to improve the working efficiency of the auxiliary winding welding mechanism 100.

[0054] The welding unit 4 includes a welding head assembly 41 and a fourth drive module 42. The fourth drive module 42 is mounted on the sliding seat 32 and is used to drive the welding head assembly 41 to move in a first direction. The welding unit 4 is used to perform welding processing on the inside of the wound magnetic core. By mounting the welding unit 4 on the sliding seat 32, the clamping unit 1, the winding limiting unit 2, and the welding unit 4 can be driven to move simultaneously by a single drive unit. This simplifies the structure of the auxiliary winding and welding mechanism 100, reduces the number of drive sources to optimize the drive, and lowers costs.

[0055] Second embodiment of auxiliary winding welding mechanism

[0056] The difference between this embodiment and the first embodiment of the auxiliary winding and welding mechanism lies in the mechanism of the second drive module. Specifically, in this embodiment:

[0057] The second drive module includes a mounting base, a second motor, and a transmission assembly. The drive end of the first drive module can also drive the mounting base to move in a first direction. The second motor is mounted on the mounting base, and the transmission assembly connects the drive shaft of the second motor and the clamping assembly. The second motor can drive the clamping assembly to rotate through the transmission assembly. Although a larger clearance space is required, this design simplifies the structure of the second drive module and improves the efficiency of the second drive module in driving the clamping assembly to rotate. The transmission assembly can be a gear set, friction wheel set, belt drive assembly, or chain drive assembly, etc.
