DETAILED DESCRIPTION

[0020] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0021] The following describes a nanocrystalline soft magnetic tape heat treatment device according to an embodiment of the present invention in conjunction with the accompanying drawings.

[0022] like Figure 1 , Figure 3 , Figure 4 As shown, the nanocrystalline soft magnetic tape heat treatment device provided by the embodiment of the present invention includes a heat treatment box 1, a transmission mechanism 3 and a heating mechanism 4, wherein the transmission mechanism 3 is arranged throughout the inside and outside of the heat treatment box 1, and the transmission mechanism 3 is used for spirally transmitting the nanocrystalline magnetic ring, and the heating mechanism 4 is arranged inside the heat treatment box 1, and the heating mechanism 4 is used for heat treatment of the nanocrystalline tape.

[0023] The transmission mechanism 3 includes a transmission drive component 31, a transmission guide rail component 32 and a transmission chain component 33, wherein the transmission chain component 33 is arranged inside the transmission guide rail component 32, the transmission drive component 31 is arranged on the transmission guide rail component 32, the transmission drive component 31 is used to drive the transmission chain component 33 to transmit and move inside the transmission guide rail component 32, and the transmission guide rail component 32 includes a spiral guide rail 324 arranged inside the heat treatment box 1.

[0024] Specifically, when the nanocrystalline magnetic ring is heat treated, the magnetic ring is first fed from the input end of the transmission guide rail assembly 32, the magnetic ring is placed on the transmission chain assembly 33, and the magnetic ring is transmitted to the spiral guide rail 324 inside the heat treatment box 1 through the transmission drive assembly 31. During the spiral rotation of the magnetic ring, the heating mechanism 4 in the heat treatment box 1 heats the heat treatment box 1. The magnetic ring is heated in all aspects during the spiral rotation on the spiral guide rail 324. The magnetic ring has a longer distance during the spiral movement and is fully heated. The entire heating process is carried out in the heat treatment box 1, and the heating space is small, saving energy consumption.

[0025] In one embodiment of the present invention, Figure 3 and Figure 4 As shown, the spiral guide rail 324 is arranged on the inner circumferential wall of the heat treatment box 1, and the heating mechanism 4 includes a heating tube 41 and a heating wire 412, wherein the heating tube 41 is vertically arranged in the middle position of the spiral guide rail 324, the heating tube 41 is a sealed structure, the heating tube 41 is made of high temperature resistant glass material, and the heating wire 412 is arranged inside the heating tube 41.

[0026] Specifically, in the process of heating the nanocrystalline magnetic ring, the heating wire 412 in the heating tube 41 is energized to radiate heat in the horizontal direction, heat-treating the magnetic ring in the horizontal direction, and heating the entire heat treatment box 1. The glass heating tube 41 provides the heating wire 412 with a better heat transmission effect, and the heating wire 412 is sealed inside the heating tube 41 to prevent the heating wire 412 from oxidation.

[0027] In one embodiment of the present invention, Figure 3 and Figure 4 As shown, the top of the spiral guide rail 324 is an open structure, and a hollow groove 325 is provided at the bottom. The inner circumferential wall of the heat treatment box 1 is also provided with a heating plate 43 with a spiral structure, and the heating plate 43 and the spiral guide rail 324 are parallel to each other.

[0028] Specifically, when the magnetic ring spirally rotates on the spiral guide rail 324, the heating plate 43 bakes and heats the upper and lower surfaces of the magnetic ring, wherein the heat at the top of the spiral guide rail 324 is received through the opening, and the heat at the bottom of the spiral guide rail 324 is received through the hollow groove 325, thereby fully heating the upper and lower end surfaces of the magnetic core.

[0029] In one embodiment of the present invention, Figure 3As shown, the heating wire 412 adopts a multi-section structure, wherein the power of the heating wire 412 in the middle portion of the heating tube 41 is greater than the power of the heating wire 412 at both ends of the heating tube 41, an electrical base 44 is provided at the bottom of the heating tube 41, and a top seat 47 is provided at the top to fix the two ends of the heating tube 41, a wire groove 45 is provided at the bottom of the heat treatment box 1, and a heating controller 46 is provided on the heat treatment box 1, and the heating controller 46 is electrically connected to the electrical base 44.

[0030] Specifically, since the heating wire 412 adopts a multi-stage structure, the power in the middle of the heating tube 41 is greater than the power at the two ends. Therefore, in the process of the magnetic ring spiraling downward, the magnetic ring passes through the low-temperature zone at the top of the heating tube 41 to be fully preheated, and then the magnetic ring enters the central high-temperature zone of the heating tube 41 to be fully heated. Finally, the magnetic ring passes through the low-temperature zone at the bottom of the heating tube 41 to be slowly cooled to prevent the magnetic ring from being deformed due to sudden heating and cooling.

[0031] Since the heating tube 41 is arranged inside the heat treatment box 1, the external heating controller 46 is connected to the wire, and the wire passes through the wire groove 45 and is connected to the bottom of the heating tube 41 to prevent the wire from being damaged by thermal fatigue and to insulate the wire and the heating controller 46.

[0032] In one embodiment of the present invention, Figure 5-Figure 7 As shown, the transmission chain assembly 33 includes a support plate 334, a bracket 335, a pin rod 336 and a movable chain plate 332, wherein the support plate 334 is arranged on the inner side of the transmission guide rail assembly 32, the pin rod 336 is arranged through the support plate 334, and two pin rods 336 are arranged on each support plate 334. The two pin rods 336 at the same end are provided with a fixed chain plate 337, and bearing rollers 333 are arranged at both ends of the pin rod 336. The movable chain plate 332 is arranged between adjacent support plates 334.

[0033] Specifically, in order to make the magnetic ring stably pass through the spiral guide rail 324, each support plate 334 is connected to each other through a movable chain plate 332, so that there is a certain twisting space between the support plates 334, which is convenient for the support plates 334 to pass through the spiral guide rail 324, thereby driving the magnetic ring to pass through the spiral guide rail 324. Bearing rollers 333 are provided at both ends of the pin rod 336 to reduce the walking resistance of the support plate 334 during the movement of the spiral guide rail 324, and balls 331 are provided at the ends of the limit stopper 339 to reduce the friction resistance between the pin shaft and both sides of the spiral guide rail 324, so that the support plate 334 can move more smoothly.

[0034] In one embodiment of the present invention, Figure 5-Figure 7As shown, a limiting baffle 339 is provided at the end of the pin rod 336, an embedding slot 3322 is provided in the middle part of the movable chain plate 332, and anti-dropping slots 3321 are provided at both ends. The upper and lower widths of the embedding slot 3322 are greater than the upper and lower widths of the anti-dropping slot 3321, the caliber of the limiting baffle 339 is greater than the width of the anti-dropping slot 3321, and the caliber of the limiting baffle 339 is smaller than the upper and lower widths of the embedding slot 3322, and a spring clip 338 for tightening the pin rod 336 is also provided inside the embedding slot 3322, and the spring clip 338 is fixed to the center position of the embedding slot 3322 by a rivet 3381.

[0035] Specifically, Figure 7 As shown, the pin 336 is inserted into the slot 3322, and the pin 336 enters the anti-dropout slot 3321 under the extrusion of the spring clip 338, and the limit stopper 339 prevents the two ends of the pin shaft from being separated from the movable chain plate 332. In addition, when the transmission chain assembly 33 moves in the spiral guide rail 324, the transmission chain assembly 33 is laterally offset along its travel direction. At this time, the pin shaft is offset in the anti-dropout slot 3321 to achieve the lateral offset of the transmission chain assembly 33, so that the transmission chain assembly 33 is easier to flexibly pass through the multi-dimensional curved spiral guide rail 324 and the hollow guide rail 321.

[0036] In one embodiment of the present invention, Figure 3-Figure 6 As shown, the bracket 335 is arranged in the middle position of the support plate 334, and the top of the bracket 335 is chamfered to facilitate the accurate placement of the magnetic ring in the bracket 335. The bottom of the bracket 335 is a mesh hollow structure, which is used for the heating plate 43 to heat the bottom of the magnetic ring.

[0037] In one embodiment of the present invention, Figure 1-Figure 5 As shown, the transmission guide rail assembly 32 also includes a hollow guide rail 321 arranged outside the heat treatment box 1, and an input guide rail 323 and an output guide rail 322 are respectively arranged at both ends of the hollow guide rail 321, wherein the input guide rail 323 is arranged at the top of the heat treatment box 1, and the input guide rail 323 is connected to the input end of the spiral guide rail 324, and the output guide rail 322 is arranged at the bottom of the heat treatment box 1, and the output guide rail 322 is connected to the output end of the spiral guide rail 324.

[0038] A driving groove 314 is provided on the feeding guide rail 323 and the discharging guide rail 322, and the transmission driving assembly 31 is arranged on the driving groove 314. The transmission driving assembly 31 includes a transmission motor 311 and a sprocket 313, wherein the transmission motor 311 is arranged outside the driving groove 314, and the sprocket 313 is arranged on the output shaft of the transmission motor 311. Two sprockets 313 are provided, and the two sprockets 313 are connected to the output shaft of the transmission motor 311 through the same rotating shaft 312. A bearing swivel 315 is provided at the end of the rotating shaft 312, and the sprocket 313 and the pin rod 336 are adapted to each other.

[0039] Specifically, during the movement of the transmission chain assembly 33 in the transmission guide rail assembly 32, the two sprockets 313 on the rotating shaft 312 are driven to rotate by the transmission motor 311, and the two sprockets 313 are meshed with the pins at both ends of the support plate 334 through the driving groove 314, thereby pushing the transmission chain assembly 33 to move in the transmission guide rail assembly 32. By arranging the transmission drive assembly 31 on both the feeding guide rail 323 and the discharging guide rail 322, the two ends of the transmission chain assembly 33 are pushed and pulled to prevent the transmission chain assembly 33 from getting stuck.

[0040] In one embodiment of the present invention, Figure 1 and Figure 3 As shown, a feeding mechanism 2 is provided on the feeding guide rail 323, and the feeding mechanism 2 is used to place the nanocrystalline magnetic ring on the bracket 335. The feeding mechanism 2 includes a feeder 21 arranged on the feeding guide rail 323, and the discharge port of the feeder 21 is provided with a discharge nozzle 22, and the discharge nozzle 22 is located above the bracket 335, and a guide plate 23 is provided at the discharge nozzle 22; a discharge mechanism 5 is provided on the delivery guide rail 322, and the discharge mechanism 5 is used to export the nanocrystalline magnetic ring that has been heat treated.

[0041] Specifically, the magnetic tape that needs heat treatment is fed from the feeder 21. After passing through the feeder 21, the magnetic ring is discharged downward from the discharge nozzle 22 and falls on the bracket 335 along the guide plate 23. The magnetic ring after heat treatment is taken out through the discharge mechanism 5. The discharge mechanism 5 can be a receiving machine or a robotic arm, or it can be taken manually.

[0042] In one embodiment of the present invention, Figure 1 As shown, an exhaust window 11 and a visual window 12 are provided on the top of the heat treatment box 1. The exhaust window 11 is used to exhaust the waste gas from the heat treatment box 1, and the visual window 12 is convenient for the operator to check the treatment status in the heat treatment box 1 at any time.

[0043] In order to clearly explain the above embodiments, refer to Figure 1-Figure 7 The specific working principle of the nanocrystalline soft magnetic tape heat treatment device of the present invention is as follows: When the nanocrystalline magnetic ring is heat-treated, the magnetic ring is first fed from the magnetic tape to be heat-treated from the feeder 21. After passing through the feeder 21, the magnetic ring is discharged downward from the discharge nozzle 22 and falls on the bracket 335 of the transmission chain assembly 33 along the guide plate 23. Then, the transmission motor 311 drives the two sprockets 313 on the rotating shaft 312 to rotate. The two sprockets 313 are meshed with the pins at both ends of the support plate 334 through the driving groove 314, thereby pushing the transmission chain assembly 33 to move in the transmission guide rail assembly 32, and the magnetic ring enters the spiral guide rail 324 along the feeding guide rail.

[0044] Since each support plate 334 is connected to each other through the movable chain plate 332, there is a certain twisting space between the support plates 334, which is convenient for the support plates 334 to pass through the spiral guide rail 324, thereby driving the magnetic ring to pass through the spiral guide rail 324. By providing bearing rollers 333 at both ends of the pin rod 336 and balls 331 at the end of the limit stopper 339, the walking resistance of the support plate 334 during the movement of the spiral guide rail 324 is reduced, so that the support plate 334 can move more smoothly.

[0045] After the magnetic ring enters the spiral guide rail 324, during the heating process of the magnetic ring, the heating wire 412 in the heating tube 41 is energized to radiate heat in the horizontal direction, heat-treating the magnetic ring in the horizontal direction, and also heating the entire heat treatment box 1. Since the heating wire 412 adopts a multi-stage structure, the power in the middle of the heating tube 41 is greater than the power at both ends. Therefore, during the downward transmission of the magnetic ring spiral, the magnetic ring passes through the low-temperature zone at the top of the heating tube 41 for sufficient preheating, and then the magnetic ring enters the central high-temperature zone of the heating tube 41 for sufficient heating, and finally the magnetic ring passes through the low-temperature zone at the bottom of the heating tube 41 for slow cooling, so as to prevent the magnetic ring from being deformed due to sudden heating and cooling.

[0046] During the spiral rotation of the magnetic ring on the spiral guide rail 324, the heating plate 43 bakes and heats the upper and lower surfaces of the magnetic ring, wherein the heat at the top of the spiral guide rail 324 is received through the opening, and the heat at the bottom of the spiral guide rail 324 is received through the hollow groove 325, so that the upper and lower end surfaces of the magnetic core are fully heated. Finally, the magnetic ring after the heat treatment is taken out through the discharging mechanism 5. The transmission chain assembly 33 continues to circulate through the hollow guide rail 321 and enters the spiral guide rail 324.

[0047] In summary, the nanocrystalline soft magnetic tape heat treatment device of the embodiment of the present invention is configured by arranging a spiral transmission guide rail in the heat treatment box and a heating mechanism in the heat treatment box, and by placing a nanocrystalline magnetic ring on the spiral guide rail, the nanocrystalline magnetic ring spirally rotates along the spiral guide rail in the heat treatment box. During the spiral rotation, the nanocrystalline magnetic ring is subjected to all-round heat treatment by the heating mechanism, and the distance of the nanocrystalline magnetic ring during the spiral movement is extended, the heating is sufficient, the heating space is small, and energy consumption is saved.

[0048] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and deform the above embodiments within the scope of the present invention.
