Abstract
Description
Technical Field
[0001] The invention belongs to the field of surface treatment of amorphous nanoribbons, and specifically refers to an insulating coating device for amorphous nanoribbons. Background Art
[0002] Amorphous nanoribbons have excellent soft magnetic properties, so they are often used to prepare the magnetic cores of devices operating under high-frequency alternating magnetic fields and are widely used in electromagnetic application fields such as inductors, transformers, and motors. At low frequencies, due to the small interlayer eddy current effect in the magnetic core, the magnetic core can usually work normally; when the magnetic core works at high frequencies (such as above 20 kHz), if the insulation between the ribbon laminations is not ideal, connectivity may occur between the layers, increasing the eddy current loss and causing a sharp increase in the high-frequency loss of the entire magnetic core. Moreover, the eddy currents inside each layer of the ribbon result in a high induced voltage between the ribbon laminations, easily causing interlayer discharge phenomena, leading to the breakdown of the ribbon laminations and even the burning of the entire magnetic core.
[0003] To improve the insulation performance between the laminations of magnetic alloy ribbons, a non-magnetic insulating material needs to be filled between the ribbon laminations as an electrical insulation layer to form a uniform coating film on the surface of the ribbon, so as to reduce or eliminate interlayer eddy currents and improve the interlayer breakdown voltage. Usually, a single-sided insulating coating is used, and the single-sided insulating coating is important for controlling the stress generated by the insulating medium on the magnetic ring during subsequent annealing to be uniform and consistent; the existing equipment controls the spraying thickness of the insulating layer by reducing the traveling speed, and the accuracy of controlling the spraying thickness is relatively low, which is not conducive to improving the insulation performance between the laminations of magnetic alloy ribbons. Summary of the Invention
[0004] In view of the above situation, to overcome the defects of the prior art, the invention creatively adopts an insulating coating device for amorphous nanoribbons to at least partially solve the problems raised in the above background art.
[0005] The technical solution adopted is as follows: The invention embodiment provides an insulating coating device for amorphous nanoribbons, including: a mounting frame, a first winding wheel, a first winding motor, an amorphous nanoribbon, an amorphous nanoribbon coating assembly, a laser thickness gauge sensor, a second winding wheel, and a second winding motor. The amorphous nanoribbon coating assembly is provided on the mounting frame, the laser thickness gauge sensor is provided on the outer wall of the amorphous nanoribbon coating assembly, the first winding wheel is provided on the left side of the amorphous nanoribbon coating assembly, the first winding wheel is connected to the first winding motor, the second winding wheel is provided on the right side of the amorphous nanoribbon coating assembly, and the second winding wheel is connected to the second winding motor.
[0006] Among them, the amorphous nanobelt coating assembly includes a protective housing, an amorphous nanobelt roller group, and an amorphous nanobelt protective roller group. The amorphous nanobelt roller group is arranged inside the protective housing, and the amorphous nanobelt roller group is connected to an amorphous nanobelt motor. The amorphous nanobelt protective roller group is arranged at the lower part of the protective housing, and the amorphous nanobelt protective roller group is connected to an amorphous nanobelt protective motor.
[0007] Among them, the roller position of the amorphous nanobelt protective roller group is directly below the roller of the amorphous nanobelt roller group.
[0008] In addition, the amorphous nanobelt exits from the upper part of the first winding wheel and then enters from the upper left side of the amorphous nanobelt roller group. The amorphous nanobelt exits from the upper right side of the amorphous nanobelt roller group and then enters from the upper part of the second winding wheel. The amorphous nanobelt exits from the lower part of the second winding wheel and then enters from the lower right side of the amorphous nanobelt roller group. The amorphous nanobelt exits from the lower left side of the amorphous nanobelt roller group and then enters from the lower part of the first winding wheel, forming a cycle.
[0009] In addition, an amorphous nanobelt protective belt is arranged on the amorphous nanobelt protective roller group.
[0010] Furthermore, the amorphous nanobelt protective belt is in the same direction as the traveling direction of the amorphous nanobelt, and the amorphous nanobelt protective belt is arranged in contact with the amorphous nanobelt.
[0011] Furthermore, the width of the amorphous nanobelt protective belt is greater than the width of the amorphous nanobelt.
[0012] Even further, the laser thickness measurement sensor is located directly above the amorphous nanobelt.
[0013] Even further, the first winding motor, the second winding motor, the amorphous nanobelt motor, and the amorphous nanobelt protective motor are connected to a signal receiving controller, and the laser thickness measurement sensor controls the rotation of the first winding motor, the second winding motor, the amorphous nanobelt motor, and the amorphous nanobelt protective motor through the signal receiving controller.
[0014] The beneficial effects obtained by adopting the above structure invention are as follows: By arranging the amorphous nanobelt protective roller group, the flatness of the amorphous nanobelt after spraying the insulating layer can be improved, and the bottom surface of the amorphous nanobelt protective belt can be prevented from being sprayed with the insulating layer, keeping the bottom surface of the amorphous nanobelt protective belt clean; The thickness signal is received by the signal receiving controller, and the rotation and roll change of the first rewinding motor, the second rewinding motor, the amorphous nanobelt motor, and the amorphous nanobelt protection motor are controlled online to achieve online control of the spraying thickness of the insulating layer of the amorphous nanobelt, and improve the insulation performance between the laminations of the magnetic alloy strip.

[0016] The drawings are used to provide a further understanding of the embodiments, and constitute a part of the specification. They are used to explain together with the present embodiments, and do not constitute a limitation to the embodiments. Detailed Embodiments
[0017] Next, the technical solutions in the embodiments will be clearly and completely described in conjunction with the drawings in the embodiments of the invention. Obviously, the described embodiments are only a part of the embodiments of the invention, rather than all the embodiments; based on the embodiments, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection.

[0019] In some embodiments, as Figure 1 shown, an amorphous nanobelt insulation coating device includes: a mounting frame 1, a first winding wheel 2, a first winding motor 3, an amorphous nanobelt 4, an amorphous nanobelt coating assembly 5, a laser thickness sensor 6, a second winding wheel 7, and a second winding motor 8. The amorphous nanobelt coating assembly 5 is provided on the mounting frame 1, the laser thickness sensor 6 is provided on the outer wall of the amorphous nanobelt coating assembly 5, the first winding wheel 2 is provided on the left side of the amorphous nanobelt coating assembly 5, the first winding wheel 2 is connected to the first winding motor 3, the second winding wheel 7 is provided on the right side of the amorphous nanobelt coating assembly 5, and the second winding wheel 7 is connected to the second winding motor 8; The thickness of the insulation layer of the amorphous nanobelt is measured by the laser thickness sensor 6 and a signal is transmitted. The first winding motor 3, the second winding motor 8, and the amorphous nanobelt motor 5.4 rotate forward. The amorphous nanobelt is unwound through the first winding wheel 2 and enters the amorphous nanobelt coating assembly 5, and is wound through the second winding wheel 7 after coming out of the amorphous nanobelt coating assembly 5, so as to realize the first unwinding and winding of the amorphous nanobelt 4 and perform a primary spraying of the insulation layer. The first winding motor 3, the second winding motor 8, and the amorphous nanobelt motor 5.4 rotate in reverse. The amorphous nanobelt is unwound through the second winding wheel 7 and enters the amorphous nanobelt coating assembly 5 again, and is wound through the first winding wheel 2 after coming out of the amorphous nanobelt coating assembly 5, so as to realize the second unwinding and winding of the amorphous nanobelt 4 and perform a secondary spraying of the insulation layer. This process of unwinding and winding is repeated until the required spraying thickness of the insulation layer of the amorphous nanobelt is reached.
[0020] As Figure 2 and Figure 3As shown in the figure, the amorphous nanobelt coating assembly 5 includes a protective housing 5.1, an amorphous nanobelt roller group 5.2, and an amorphous nanobelt protective roller group 5.3. The top of the protective housing 5.1 is an open frame. Inside the protective housing 5.1, there is an amorphous nanobelt roller group 5.2. The amorphous nanobelt roller group 5.2 is connected to an amorphous nanobelt motor 5.4, and the amorphous nanobelt motor 5.4 provides drive for the amorphous nanobelt roller group 5.2. At the lower part of the protective housing 5.1, there is an amorphous nanobelt protective roller group 5.3. The amorphous nanobelt protective roller group 5.3 is connected to an amorphous nanobelt protective motor 5.5, and the amorphous nanobelt protective motor 5.5 provides drive for the amorphous nanobelt protective roller group 5.3.
[0021] The roller position of the amorphous nanobelt protective roller group 5.3 is directly below the roller of the amorphous nanobelt roller group 5.2.
[0022] As Figure 4 shown, the first winding motor 3, the second winding motor 8, and the amorphous nanobelt motor 5.4 rotate forward. The amorphous nanobelt 4 exits from the upper part of the first winding wheel 2 and then enters from the lower left side of the amorphous nanobelt roller group 5.2, realizing the unwinding of the amorphous nanobelt 4. The amorphous nanobelt 4 exits from the lower right side of the amorphous nanobelt roller group 5.2 and then enters from the upper part of the second winding wheel 7, realizing the winding of the amorphous nanobelt 4. When a roll of amorphous nanobelt 4 has been sprayed with an insulating layer once, the first winding motor 3, the second winding motor 8, and the amorphous nanobelt motor 5.4 rotate in reverse. The amorphous nanobelt 4 exits from the upper part of the second winding wheel 7 and then enters from the lower right side of the amorphous nanobelt roller group 5.2, realizing the unwinding of the amorphous nanobelt 4. The amorphous nanobelt 4 exits from the lower left side of the amorphous nanobelt roller group 5.2 and then enters from the upper part of the first winding wheel 2, realizing the winding of the amorphous nanobelt 4, and realizing the continuous spraying of the insulating layer on the amorphous nanobelt until the required spraying thickness is reached.
[0023] As Figure 5 shown, an amorphous nanobelt protective belt 9 is provided on the amorphous nanobelt protective roller group 5.3; The amorphous nanobelt protective belt 9 is in the same direction as the traveling direction of the amorphous nanobelt 4, and the amorphous nanobelt protective belt 9 is in contact with the amorphous nanobelt 4; The width of the amorphous nanobelt protective belt 9 is greater than the width of the amorphous nanobelt 4, avoiding curling and unevenness of the amorphous nanobelt 4; The bottom amorphous nanobelt protection belt 9 is driven by the amorphous nanobelt protection roller group 5.3. The amorphous nanobelt protection belt 9 levels the amorphous nanobelt 4 after the insulating layer is sprayed, avoiding wrinkles in the amorphous nanobelt 4 after the insulating layer is sprayed, and can prevent the bottom surface of the amorphous nanobelt protection belt 9 from being sprayed with the insulating layer, keeping the bottom surface of the amorphous nanobelt protection belt 9 clean.
[0024] As Figure 1 shown, the amorphous nanobelt 4 is located in the middle of the laser thickness gauge sensor 6, enabling the laser thickness gauge sensor to detect the spraying thickness of the insulating layer of the amorphous nanobelt 4 and transmit signals.
[0025] The first winding motor 3, the second winding motor 8, the amorphous nanobelt motor 5.4 and the amorphous nanobelt protection motor 5.5 are connected to the signal receiving controller 10. The laser thickness gauge sensor 6 controls the rotation of the first winding motor 3, the second winding motor 8, the amorphous nanobelt motor 5.4 and the amorphous nanobelt protection motor 5.5 through the signal receiving controller 10.
[0026] In the present invention, through the laser thickness gauge sensor 6, the laser thickness gauge sensor 6 is a sensor that can sense the thickness of the object to be measured and convert it into an available output signal such as an analog current-voltage signal or a digital signal. The signal receiving controller 10 sets a standard value. When the spraying thickness of the insulating layer of the amorphous nanobelt 4 reaches the standard value set by the signal receiving controller 10, the signal receiving controller 10 controls the rotation of the first winding motor 3, the second winding motor 8, the amorphous nanobelt motor 5.4 and the amorphous nanobelt protection motor 5.5 to slow down and issues an alarm signal to achieve roll change.
[0027] The present invention is provided with a spraying assembly 11 on the upper part of the amorphous nanobelt coating assembly 5, and a plurality of spraying heads 12 are provided on the spraying assembly 11. The first winding motor 3, the second winding motor 8 and the amorphous nanobelt motor 5.4 rotate forward, and the amorphous nanobelt 4 is wound out from the upper part of the first winding wheel 2 and then wound into the lower left side of the amorphous nanobelt roller group 5.2 to realize the unwinding of the amorphous nanobelt 4. When the amorphous nanobelt 4 passes through the plurality of spraying heads 12, the insulating layer of the amorphous nanobelt 4 is sprayed. The amorphous nanobelt 4 is wound out from the lower right side of the amorphous nanobelt roller group 5.2 and then wound into the upper part of the second winding wheel 7 to realize the winding of the amorphous nanobelt 4. After a roll of amorphous nanobelt 4 passes through the spraying insulation layer once, the first winding motor 3, the second winding motor 8 and the amorphous nanobelt are rotated forward. The motor 5.4 rotates in reverse, and the amorphous nanobelt 4 is wound out from the upper part of the second winding wheel 7 and then wound into the lower right side of the amorphous nanobelt roller group 5.2 to realize the unwinding of the amorphous nanobelt 4. When the amorphous nanobelt 4 passes through multiple spray heads 12, the insulating layer of the amorphous nanobelt 4 is sprayed for the second time. The amorphous nanobelt 4 is wound out from the lower left side of the amorphous nanobelt roller group 5.2 and then wound into the upper part of the first winding wheel 2 to realize the winding of the amorphous nanobelt 4, and the continuous spraying of the amorphous nanobelt insulating layer is realized until the required spraying thickness is reached. When the required spraying thickness is reached, the signal receiving controller 10 controls the first winding motor 3, the second winding motor 8, the amorphous nanobelt motor 5.4 and the amorphous nanobelt protection motor 5.5 to slow down the rotation, and sends an alarm signal to realize the roll change.

[0029] The above description of the embodiment is non-limiting. The drawings show only one embodiment, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by this and, without departing from the purpose of the invention, designs a similar structure and embodiment without inventiveness, they shall fall within the scope of protection.
