[0059] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0060] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0061] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0062] In the description of this embodiment, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0063] The present embodiment provides an amorphous nanocrystalline magnetic core winding machine, which has high operating reliability, high winding uniformity of the processed magnetic cores, and low failure rate, which reduces maintenance costs and saves maintenance time, thereby improving the production efficiency of amorphous nanocrystalline magnetic cores.

[0064] Specifically, Figure 1-Figure 7 As shown, the amorphous nanocrystalline winding machine includes a frame (not shown in the figure), a tape unwinding mechanism 100 for releasing the amorphous nanocrystalline tape 20, a tape conveying track 200 for conveying the amorphous nanocrystalline tape 20, a tape pressing mechanism 300 for pressing the amorphous nanocrystalline tape 20, a winding mechanism 400 for winding the amorphous nanocrystalline tape 20 into a magnetic core 10, a tape cutting mechanism 500 for cutting the amorphous nanocrystalline tape 20, and a welding mechanism 600 for welding the two ends of the wound magnetic core 10.

[0065] The strip pressing mechanism 300 includes a base 310 disposed on one side of the strip conveying track 200 and a pressing assembly 320 disposed on the base 310. The pressing assembly 320 includes a strip pressing arm 321 extending in the direction of the strip conveying track 200, and the strip pressing arm 321 is detachably mounted with a wear strip 3211 facing the bottom surface of the strip conveying track 200, and the outer surface of the wear strip 3211 protruding from the strip pressing arm 321 is an arc surface, and the strip pressing arm 321 can rotate relative to the base 310, so that the arc surface of the wear strip 3211 presses the amorphous nanocrystalline strip 20 on the strip conveying track 200.

[0066] If the wear-resistant strip 3211 is not provided, the belt pressing arm 321 will press the belt toward the bottom surface of the belt conveying track 200. After a period of use, the bottom surface of the belt pressing arm 321 will be worn. When the bottom surface of the belt pressing arm 321 is worn, the pressure applied to the amorphous nanocrystalline belt 20 will decrease. This slight decrease in pressure is difficult to detect, so the equipment continues to run, resulting in difficulty in ensuring the uniformity of the processed magnetic core 10. In addition, when the pressure of the belt pressing arm 321 is completely unable to meet the belt pressing requirements, the entire clamping assembly 320 needs to be replaced, and the maintenance cost is high and the maintenance time is also long.

[0067] In this embodiment, the wear-resistant strip 3211 is provided. When the wear-resistant strip 3211 is worn, the wear-resistant strip 3211 can be directly replaced without replacing the entire clamping assembly 320. The maintenance cost is low and the maintenance time is short. Moreover, after the wear-resistant strip 3211 is worn, the belt pressing arm 321 can be rotated to make the unworn part of the wear-resistant strip 3211 contact with the amorphous nanocrystalline strip 20 to achieve belt pressing, thereby extending the service life of the wear-resistant strip 3211. Compared with not providing the wear-resistant strip 3211, the failure rate of the equipment is greatly reduced.

[0068] The welding mechanism 600 includes an external welding assembly 610 for welding the outer end of the magnetic core 10. The external welding assembly 610 includes a first driving member arranged on a frame, a fixing assembly 611 connected to the output end of the first driving member, and two groups of welding needle groups 612 with different lengths arranged on the fixing assembly 611. The welding needle groups 612 include a long welding needle group 6121 close to the frame and a short welding needle group 6122 arranged parallel to the long welding needle group 6121 and away from the frame. The first driving member drives the fixing assembly 611 to move to switch the two groups of welding needle groups 612 between the initial position and the welding position.

[0069] It is worth noting that the initial position is far away from the magnetic core 10 to avoid interfering with the winding of the magnetic core 10 ; the welding position is close to the magnetic core 10 , and at the welding position, the two groups of welding needles 612 weld the outer ends of the magnetic core 10 .

[0070] During welding, the two welding needle groups 612 need to contact the outermost amorphous nanocrystalline strip 20 of the magnetic core 10 at the same time to form a current loop. If the two welding needle groups 612 have the same length, the heads of the two welding needle groups 612 need to be kept in the same plane when they are installed to ensure that the heads of the two welding needle groups 612 can contact the amorphous nanocrystalline strip 20 at the same time. This requires high installation accuracy. In addition, the heads of the welding needle groups 612 are prone to wear and must be replaced with new ones after wear, resulting in high equipment failure rates and maintenance costs.

[0071] In this embodiment, the lengths of the two welding needle groups 612 are set to be different. During welding, the bottom plane of the long welding needle group 6121 contacts the amorphous nanocrystalline strip 20 of the outermost layer of the magnetic core 10, and the head of the short welding needle group 6122 contacts the amorphous nanocrystalline strip 20. With this setting, the assembly accuracy requirements of the long welding needle group 6121 and the short welding needle group 6122 are not high, and the welding requirements can be met. In addition, the space occupied by the short welding needle group 6122 is greatly reduced, which can effectively avoid interference with other mechanisms.

[0072] The amorphous nanocrystalline magnetic core winding machine provided in this embodiment improves the belt pressing assembly and the welding mechanism 600, so that the magnetic core 10 processed by the amorphous nanocrystalline magnetic core winding machine has higher winding uniformity, and reduces the failure rate of the belt pressing mechanism and the welding mechanism 600, reduces maintenance costs, saves maintenance time, and thus improves the production efficiency of the amorphous nanocrystalline magnetic core 10.

[0073] Optionally, in this embodiment, the wear-resistant strip 3211 is a cylinder.

[0074] It can be understood that the long solder pin group 6121 may include multiple solder pins, and similarly, the short solder pin group 6122 may also include multiple solder pins.

[0075] Optionally, continue to see Figure 2 and Figure 3 The strip clamping mechanism 300 also includes a magnetic part 330 which is arranged on the frame and can adjust the magnetic attraction force. The clamping assembly 320 also includes a transmission arm 322 which rotates synchronously with the strip pressing arm 321 along the same rotating axis. The end surface of the transmission arm 322 close to the magnetic part 330 is adsorbed and connected with the magnetic part 330, and the rotation angle of the transmission arm 322 can be adjusted by controlling the magnetic attraction force of the magnetic part 330, thereby controlling the rotation angle of the strip pressing arm 321 in linkage.

[0076] Specifically, when the magnetic attraction is small, the transmission arm 322 is away from the magnetic part 330, thereby driving the belt pressing arm 321 to lift upward, so that the wear-resistant strip 3211 on the belt pressing arm 321 exerts a small pressure on the amorphous nanocrystalline strip 20; when the magnetic attraction is large, the transmission arm 322 is close to the magnetic part 330, thereby driving the belt pressing arm 321 to press downward, so that the wear-resistant strip 3211 on the belt pressing arm 321 exerts a large pressure on the amorphous nanocrystalline strip 20. That is, the belt pressing mechanism can control the pressure of the wear-resistant strip 3211 on the belt pressing arm 321 on the amorphous nanocrystalline strip 20 by controlling the magnetic attraction of the magnetic part 330, and the adjustment is simple and convenient, without the need to shut down the equipment, which greatly improves the reliability of the operation of the amorphous nanocrystalline magnetic core winding machine.

[0077] Optionally, in this embodiment, the belt holding arm 321 and the transmission arm 322 are an integrated structure, and a connection hole is provided at the connection between the belt holding arm 321 and the transmission arm 322, and the connection hole is sleeved on the rotating shaft. The belt holding arm 321 and the transmission arm 322 are set as an integrated structure, which can reliably ensure that the belt holding arm 321 and the transmission arm 322 rotate synchronously, and is easy to process and install.

[0078] Furthermore, the transmission arm (322) is arranged in the vertical direction. This arrangement makes the magnetic attraction between the transmission arm 322 and the magnetic member 330 relatively stable, thereby improving the stability of the belt pressing force of the belt pressing arm 321.

[0079] The transmission arm 322 and the belt pressing arm (321) may also be arranged at an angle less than 90 degrees, so that when the magnetic attraction between the magnetic member 330 and the transmission arm 322 is large, the pressure of the belt pressing arm 321 on the amorphous nanocrystalline ribbon 20 is also large.

[0080] Preferably, continue to see Figure 2 and Figure 3 On the strip conveying track 200, a groove is provided at a position corresponding to the strip pressing arm 321, and an elastic pad 340 is installed in the groove. The upper surface of the elastic pad 340 is flush with the conveying surface of the strip conveying track 200, and the wear-resistant strip 3211 presses the amorphous nanocrystalline strip 20 against the elastic pad 340. By providing the elastic pad 340, when the wear-resistant strip 3211 applies a pressing force to the amorphous nanocrystalline strip 20, the elastic pad 340 can buffer the pressing force through elastic deformation, thereby protecting the amorphous nanocrystalline strip 20 to a certain extent, and will not affect the size of the pressing force, thereby ensuring the pressing effect. At the same time, the elastic pad 340 is in direct flexible contact with the amorphous nanocrystalline strip 20, which can reduce the friction loss of the amorphous nanocrystalline strip 20.

[0081] Preferably, the wear-resistant strip 3211 is made of an elastic material, such as rubber. On the one hand, it has strong wear resistance, so that its service life is longer; on the other hand, it can effectively protect the amorphous nanocrystalline strip 20.

[0082] Further, see Figure 4 The fixing assembly 611 includes a fixing seat 6111, a soldering pin seat 6112 and a first elastic member 6113. The fixing seat 6111 is connected to the output end of the first driving member, the middle area of ​​the soldering pin seat 6112 is rotatably connected to the fixing seat 6111, the first end of the soldering pin seat 6112 is elastically connected to the fixing seat 6111 through the first elastic member 6113, and the second end of the soldering pin seat 6112 is provided with two soldering pin groups 612. In addition, the first end of the soldering pin seat 6112 and the second end of the soldering pin seat 6112 are respectively placed at the two ends of the rotation center of the soldering pin seat 6112.

[0083] When two groups of welding needles 612 are welded, the first elastic member 6113 is in a compressed state, so that the first elastic member 6113 can push up the first end of the welding needle seat 6112 under the action of the elastic restoring force, thereby enabling the two groups of welding needle groups 612 on the second end of the welding needle seat 6112 to always press on the magnetic core 10, thereby improving the reliability of the welding work of the welding needle group 612.

[0084] Optionally, one or more first elastic members 6113 may be provided, depending on actual needs, and this application does not make any specific limitation.

[0085] Further, see Figure 4The ends of the welding pins of the short welding pin group 6122 are all provided with a chamfered surface 61221, and the chamfered surface 61221 faces the magnetic core 10. In this way, the welding pins of the short welding pin group 6122 can better contact with the magnetic core 10 through the chamfered surface 61221, and even if the welding pin heads of the short welding pin group 6122 are slightly worn, it will not affect the formation of a current loop between the two welding pin groups 612, thereby reducing the probability of failure and shutdown of the above-mentioned amorphous nanocrystalline magnetic core winding machine.

[0086] It is worth noting that, in this embodiment, the chamfered surface 61221 is inclined from the upper surface of the solder pins in the short solder pin group 6122 toward the magnetic core 10. The chamfered surface 61221 can also be formed by cutting off the edge formed by connecting the side and bottom surfaces of the solder pins.

[0087] Further, see Figure 1 The welding mechanism 600 also includes an internal welding component 620. The winding mechanism 400 includes a winding needle, which is hollow inside and has a notch. The welding needle 612 of the internal welding component 620 can extend into the winding needle to weld the inner end of the magnetic core 10 through the notch.

[0088] Furthermore, if Figure 5 and Figure 6 As shown, the unwinding mechanism 100 includes a turntable 110, a second driving member (not shown in the figure), a reel 120 and a reducing ring 130. Among them, the second driving member is arranged on the frame, and the output end of the second driving member is connected to the turntable 110, and is used to drive the turntable 110 to rotate around the center of the turntable 110. One end of the reel 120 is fixedly connected to the center of the turntable 110. The reducing ring 130 includes an inner ring 131 sleeved outside the reel 120 and an outer ring 132 for fixing the amorphous nanocrystalline strip 20, and the diameter of the outer ring 132 is adjustable. The disc-shaped amorphous nanocrystalline strip 20 is sleeved on the outer ring 132 of the reducing ring 130, and the second driving member is controlled to drive the turntable 110 to rotate, which can drive the reel 120 to rotate, and the reel 120 can rotate synchronously with the reducing ring 130 installed thereon, and the reducing ring 130 can rotate to drive the disc-shaped amorphous nanocrystalline strip 20 installed thereon to rotate, so as to realize unwinding. Since the inner ring specifications of the incoming amorphous nanocrystalline ribbons 20 are not uniform, the outer ring 132 of the reducing ring 130 is adjustable in diameter so that it can be applied to amorphous nanocrystalline ribbons 20 of various specifications, thereby improving the universality of the unwinding mechanism 100 .

[0089] Optionally, continue to see Figure 6In this embodiment, the peripheral wall of the inner ring 131 is provided with a plurality of threaded holes 1311 arranged in the circumferential direction, each threaded hole 1311 is connected to a screw rod 133, an arc block 134 is provided at one end of the screw rod 133 away from the inner ring 131, and a plurality of arc blocks 134 surround the outer ring 132. When the diameter of the outer ring 132 needs to be adjusted, the screwing depth of the screw rod 133 and the threaded hole 1311 can be adjusted at the same time. The reducer ring 130 has a simple structure and the diameter of the outer ring 132 is easy to adjust.

[0090] Further, see Figure 5 The unwinding mechanism 100 further includes a baffle 140, a fixing pin 150 and a second elastic member 160. A center hole is provided at the center of the baffle 140, and the winding roller 120 is slidably inserted into the center hole. The fixing pin 150 is detachably mounted on an end of the winding roller 120 away from the turntable 110. The second elastic member 160 is sleeved on the winding roller 120, and one end of the second elastic member 160 is connected to the plate surface of the baffle 140 away from the turntable 110, and the other end is connected to the fixing pin 150.

[0091] The steps of installing the amorphous nanocrystalline ribbon 20 on the ribbon unwinding mechanism 100 are as follows:

[0092] First, after adjusting the diameter of the outer ring 132 of the reducer ring 130, the reducer ring 130 is installed on the winding roller 120;

[0093] Then, the amorphous nanocrystalline ribbon 20 is mounted on the reducing ring 130;

[0094] Afterwards, the baffle plate 140 is installed on the winding roller 120;

[0095] Finally, the fixing pin 150 is mounted on the winding roller 120 .

[0096] By providing the baffle 140, the baffle 140 can be used together with the turntable 110 to clamp the amorphous nanocrystalline ribbon 20, so as to prevent the amorphous nanocrystalline ribbon 20 from loosening during the unwinding process and affecting the unwinding speed. By providing the second elastic member 160, the baffle 140 can be always pressed on the amorphous nanocrystalline ribbon 20 under the action of elastic force, which can not only ensure the compacting effect on the amorphous nanocrystalline ribbon 20, but also make it applicable to amorphous nanocrystalline ribbons 20 of various widths, and has high universality.

[0097] Furthermore, if Figure 1 and Figure 7As shown, the above-mentioned amorphous nanocrystalline magnetic core winding machine also includes a magnetic core outer diameter detection mechanism 700, and the magnetic core outer diameter detection mechanism 700 includes an outer diameter sensing ring 710 and a third driving member 720. The outer diameter sensing ring 710 is used to obtain the outer diameter of the magnetic core 10 wound on the winding mechanism 400, and the third driving member 720 is arranged on the frame. The output end of the third driving member 720 is connected to the outer diameter sensing ring 710, which is used to adjust the distance between the outer diameter sensing ring 710 and the winding mechanism 400.

[0098] When making the magnetic core 10, there are different requirements for the diameter of the magnetic core 10. Therefore, before winding, the outer diameter induction ring 710 is first transported to one side of the winding mechanism 400 through the third driving member 720, so that the distance between the outer diameter induction ring 710 and the winding needle of the winding mechanism 400 is a preset diameter. During the process of the winding mechanism 400 winding the magnetic core 10, if the outer diameter induction ring 710 senses the magnetic core 10, the winding mechanism 400 stops winding. By setting the magnetic core outer diameter detection mechanism 700, the diameter of the wound magnetic core 10 can be intelligently controlled. In addition, the diameter detection mechanism of the magnetic core 10 has a simple structure and is easy to control.

[0099] Further, see Figure 1 and Figure 7 , a boss 210 is provided on one side of the strip conveying track 200 close to the frame, and one end of the amorphous nanocrystalline strip 20 in the width direction abuts against the boss 210. The above-mentioned amorphous nanocrystalline magnetic core winding machine also includes a limiting mechanism 800, and the limiting mechanism 800 includes a limiting push rod 810, and the limiting push rod 810 can move between the strip cutting mechanism 500 and the winding mechanism 400, and abut against the other end of the amorphous nanocrystalline strip 20 in the width direction. Through the cooperation of the limiting push rod 810 and the boss 210, the opposite ends of the amorphous nanocrystalline strip 20 in the width direction can be limited, thereby improving the stability of the amorphous nanocrystalline strip 20 conveying, and further facilitating the uniformity of the wound magnetic core 10.

[0100] Further, see Figure 1 and Figure 7 The above-mentioned amorphous nanocrystalline magnetic core winding machine further includes a pushing mechanism 900, which includes a fourth driving member 910 and a push plate 920 connected to the output end of the fourth driving member 910. The fourth driving member 910 is used to drive the push plate 920 to flatten the side of the magnetic core 10 on the winding mechanism 400. When the winding mechanism 400 stops winding, the fourth driving member 910 is controlled to drive the push plate 920 to press the side of the magnetic core 10, so that the side edges of the amorphous nanocrystalline strip 20 of each circle of the magnetic core 10 are located in the same plane, that is, the side of the magnetic core 10 is flattened, and then welded by the external welding assembly 610. By setting the pushing mechanism 900, the quality of the magnetic core 10 can be improved.

[0101] Further, see Figure 1 The above-mentioned amorphous nanocrystalline magnetic core winding machine also includes a weighing mechanism 1000, a qualified product receiving tray 1100, a failed product receiving tray 1200, a grasping mechanism 1300 and a pushing mechanism 1400.

[0102] The weighing mechanism 1000 is used to obtain the weight of the wound magnetic core 10 .

[0103] The qualified product receiving tray 1100 and the unqualified product receiving tray 1200 are respectively arranged on both sides of the weighing mechanism 1000.

[0104] The grabbing mechanism 1300 is used to transfer the wound magnetic core 10 to the weighing mechanism 1000 .

[0105] The pushing mechanism 1400 includes a pushing rod 1410 , which can push qualified products into the qualified product receiving tray 1100 and push unqualified products into the unqualified product receiving tray 1200 according to the weighing result of the weighing mechanism 1000 .

[0106] Specifically, after the wound magnetic core 10 is welded, the gripping mechanism 1300 will take the magnetic core 10 off the winding mechanism 400 and transfer it to the weighing mechanism 1000, which will weigh the magnetic core 10. If the weight meets the requirements, it is a qualified product, and if the weight does not meet the requirements, it is a defective product. Then, the push rod 1410 pushes the qualified products into the qualified product receiving tray 1100 and pushes the defective products into the defective product receiving tray 1200.

[0107] Optionally, in this embodiment, the grabbing mechanism 1300 includes a rotating driving member 1310 and a claw 1320 , and the rotating driving member 1310 is connected to the claw 1320 , and the claw 1320 grabs the magnetic core 10 and transfers the magnetic core 10 to the weighing mechanism 1000 by rotating.

[0108] Further, see Figure 1 In order to ensure that the magnetic core 10 falling from the weighing mechanism 1000 can reliably fall into the qualified product receiving tray 1100 or the unqualified product receiving tray 1200, a slide 1600 is provided between the weighing mechanism 1000 and the qualified product receiving tray 1100, and between the weighing mechanism 1000 and the unqualified product receiving tray 1200.

[0109] Preferably, continue to see Figure 1 In this embodiment, the above-mentioned amorphous nanocrystalline magnetic core winding machine also includes a belt conveyor 1500, and the internal welding component 620, the fourth driving member 910, the limiting mechanism 800 and the grabbing mechanism 1300 are all arranged on the belt conveyor 1500, and the belt conveyor 1500 transports each part to the work station.
