Description

Technical Field

[0001] The present invention relates to the field of winding and unwinding equipment, and more particularly to a precision winding device for amorphous magnetic rings. Background Art

[0002] An amorphous magnetic ring refers to a magnetic component processed from amorphous materials. According to the shape of the material, it can be divided into strip-type magnetic rings and powder-type magnetic rings.

[0003] In the related art, a large-sized amorphous magnetic ring is disclosed. The unwinding device sequentially unwinds the amorphous strips of multiple small-sized amorphous magnetic rings, and the winding device winds the multiple unwound amorphous strips into a large-sized amorphous magnetic ring.

[0004] Since there are many impurities such as dust and powder in the air, and the impurities may float and adhere to the amorphous strip. During the process of winding the amorphous strip into a large-sized amorphous magnetic ring, the impurities may be wrapped in the large-sized amorphous magnetic ring, thus affecting the use effect of the amorphous magnetic ring, which has obvious deficiencies. Summary of the Invention

[0005] In order to improve the problem that impurities may be wrapped in the amorphous magnetic ring and affect its use quality, the present application provides a precision winding device for amorphous magnetic rings.

[0006] The precision winding device for amorphous magnetic rings provided by the present application adopts the following technical solutions:

[0007] A precision winding device for amorphous magnetic rings includes a first mounting plate seat disposed between a winding device and an unwinding device. A base is provided on the first mounting plate seat. A bearing plate is provided at a position above the base relative to the first mounting plate seat. A cylinder is provided on the bearing plate. The piston rod of the cylinder passes through the bearing plate and is connected to a pressing plate for pressing the amorphous strip against the base. A felt layer is provided on the lower surface of the pressing plate.

[0008] By adopting the above technical solutions, the amorphous strip passes through between the felt layer and the base. Since the felt layer is relatively delicate, it can wipe off the dust, powder and other particles attached to the amorphous strip, which is beneficial to improving the purity of the amorphous magnetic ring and further improving the use quality of the amorphous magnetic ring.

[0009] Optionally, the first mounting plate seat is vertically disposed, and the pressing plate is L-shaped and closely adheres to the first mounting plate seat.

[0010] By adopting the above technical solutions, the close adhesion between the pressing plate and the first mounting plate seat can play a guiding role in the lifting movement of the pressing plate.

[0011] Optionally, a sliding seat is provided at a position below the first mounting plate seat relative to the base. A sliding groove for the base to slide is formed in the upper surface of the sliding seat along the width direction of the amorphous strip. A rotating stud head that extends into the sliding groove and has a connecting column at its end is threadedly connected to the sliding seat. A rotating hole for the connecting column to rotate is formed in the base. A sealing plate for closing the rotating hole is slidably and rotatably sleeved on the rotating stud head, and the sealing plate is connected to the base.

[0012] By adopting the above technical solution, the worker manually twists the rotating stud head, and the rotating stud head drives the connecting column to rotate in the rotating hole, thereby being able to drive the base to move along the width direction of the amorphous strip, realizing the adjustment of the loading position of the amorphous strip, and thus being applicable to the deburring work of amorphous strips with different widths.

[0013] Optionally, two guiding strips parallel to the width direction of the amorphous strip are provided at positions of the sliding seat relative to the bottom wall of the sliding groove. A guiding groove with a dovetail-shaped longitudinal section that slides on the two guiding strips is formed at the bottom of the base. The longitudinal section of the guiding strip is a right-angled trapezoid, and the side wall corresponding to the hypotenuse of the trapezoid is in close contact with the side wall of the guiding groove.

[0014] By adopting the above technical solution, the sliding fit between the guiding strip and the guiding groove plays a guiding role in the movement of the base.

[0015] Optionally, a second mounting plate seat is further provided between the first mounting plate seat and the unwinding device. Two concave-shaped clamping seats are arranged on the second mounting plate seat along the width direction of the amorphous strip. Two pressing strips are vertically stacked between the grooves of the two clamping seats, and the amorphous strip passes through between the two pressing strips.

[0016] By adopting the above technical solution, the upper pressing strip presses the amorphous strip against the lower pressing strip by gravity. When the amorphous strip passes through between the two pressing strips, the two pressing strips cooperate to scrape off the burrs at the two side edges of the length of the amorphous strip.

[0017] Optionally, bearing strips are provided at positions below the first mounting plate seat relative to the sliding seat and below the second mounting plate seat relative to the clamping seat. Adjusting grooves are vertically formed on both the first mounting plate seat and the second mounting plate seat. Adjusting bolts are provided on one side of the first mounting plate seat and the second mounting plate seat facing away from the corresponding bearing strips. The adjusting bolts pass through the adjusting grooves and are threadedly connected to the corresponding bearing strips.

[0018] By adopting the above technical solution, the worker adjusts the height of the base and the pressing strip by loosening and tightening the adjusting bolts, thereby improving the deburring and particle removal effects on the amorphous strip.

[0019] Optionally, a third mounting seat is further arranged between the second mounting seat and the unwinding device, and a magnetic roller for magnetically attracting the amorphous ribbon is arranged on the third mounting seat.

[0020] By adopting the above technical solution, the magnetic attraction of the magnetic roller to the amorphous ribbon can reduce the possibility of the amorphous ribbon unwound by the unwinding device swinging randomly.

[0021] Optionally, a bearing rod is arranged on the third mounting seat, and the magnetic roller is rotatably sleeved on the bearing rod.

[0022] By adopting the above technical solution, during the feeding process of the amorphous ribbon, the magnetic roller can be driven to rotate on the bearing rod, thereby reducing the possibility of the amorphous ribbon being worn.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The amorphous ribbon passes through between the felt layer and the base. Since the felt layer is relatively delicate, it can wipe off the dust, dust and other particles attached to the amorphous ribbon, which is beneficial to improving the purity of the amorphous magnetic ring and thus improving the service quality of the amorphous magnetic ring;

[0025] 2. The worker manually twists the rotating stud head, and the rotating stud head drives the connecting column to rotate in the rotating hole, thereby driving the base to move along the width direction of the amorphous ribbon, realizing the adjustment of the bearing position of the amorphous ribbon, and thus being applicable to the particle removal work of amorphous ribbons with different widths;

[0026] 3. The upper pressing strip presses the amorphous ribbon against the lower pressing strip by gravity. When the amorphous ribbon passes through between the two pressing strips, the two pressing strips cooperate to scrape off the burrs at both edges of the length of the amorphous ribbon.

[0032] The following is a further detailed description of the present application in conjunction with the attached Figures 1 - 4 drawings.

[0033] An embodiment of the present application discloses a precision rewinding device for amorphous magnetic rings.

[0034] Referring to Figure 1 , the precision rewinding device for amorphous magnetic rings includes an unwinding device 1, a deburring device 2, a particle removing device 3 and a rewinding device 5 arranged in sequence. The unwinding device 1 and the rewinding device 5 directly adopt the existing technologies.

[0035] Referring to Figure 1 , the unwinding device 1 unwinds the amorphous strip of the small-sized amorphous magnetic ring, the deburring device 2 deburrs the amorphous strip, the particle removing device 3 wipes off the fine particles on the amorphous strip, and the rewinding device 5 winds the amorphous strip into a large-sized amorphous magnetic ring.

[0036] Referring to Figure 1 , the rewinding device 5 includes a cabinet 51 placed on the ground and in a rectangular shape, and both the deburring device 2 and the particle removing device 3 are arranged outside the cabinet 51.

[0037] Referring to Figure 1 , Figure 2 and Figure 3 , since there is a certain distance between the unwinding device 1 and the deburring device 2, a vertical third mounting plate seat 10 is bolted to the position of the cabinet 51 relative to the deburring device 2 and the unwinding device 1. A horizontal bearing rod 11 is arranged on one side of the third mounting plate seat 10 relative to the amorphous strip, and a magnetic roller 12 is rotatably sleeved on the bearing rod 11 through a bearing.

[0038] Referring to Figure 1 , Figure 2 and Figure 3 , the magnetic roller 12 adsorbs the amorphous strip, so as to limit the amorphous strip, reducing the possibility of the unwound amorphous strip swinging wantonly. During the feeding process of the amorphous strip, it can drive the magnetic roller 12 to rotate on the bearing rod 11.

[0039] The carrier rod 11 is installed on the third mounting plate base 10 in a detachable manner, so that the worker can adjust the height of the magnetic roller 12. A guiding roller 13 with adjustable height is also arranged above the magnetic roller 12. The arrangement of the guiding wheel enables the amorphous strip to enter the deburring device 2 horizontally.

[0040] Referring to Figure 1 、 Figure 2 and Figure 3 , the deburring device 2 includes a second mounting plate base 21 which is vertical and bolted to the cabinet 51 at the bottom. On one side of the second mounting plate base 21 opposite to the amorphous strip, there is a horizontal load-bearing strip 7. The load-bearing strip 7 is parallel to the width direction of the amorphous strip and one end of it abuts against the second mounting plate base 21.

[0041] An adjustment slot 8 is vertically opened on the second mounting plate base 21. On the other side of the second mounting plate base 21 opposite to the load-bearing strip 7, there is an adjustment bolt 9. The adjustment bolt 9 passes through the adjustment slot 8 and is threadedly connected to the corresponding load-bearing strip 7.

[0042] The worker rotates the adjustment bolt 9 through a tool. Under the action of the thread, the adjustment bolt 9 and the load-bearing strip 7 approach each other, so as to cooperate to clamp the first mounting plate base 31.

[0043] Referring to Figure 1 、 Figure 2 and Figure 3 , two clamping seats 22 are bolted along the length direction of the load-bearing strip 7. Both of the two clamping seats 22 are arranged in a concave shape. The grooves of the clamping seats 22 face upward. Two pressing strips 23 are vertically stacked between the grooves of the two clamping seats 22. The amorphous strip passes through between the two pressing strips 23.

[0044] Referring to Figure 1 、 Figure 2 and Figure 3 , the upper pressing strip 23 presses the amorphous strip tightly on the lower pressing strip 23 by gravity. When the amorphous strip passes through between the two pressing strips 23, the two pressing strips 23 cooperate to remove the burrs on both sides of the length of the amorphous strip, and can also intercept impurities such as dust and powder attached to the amorphous strip.

[0045] In addition, the pressing strip 23 itself has a certain weight. Therefore, when the amorphous strip passes through between the two pressing strips 23, the upper pressing strip 23 can play a certain role in straightening the amorphous strip.

[0046] Referring to Figure 1 、 Figure 2 and Figure 3 , the arrangement of the adjustment slot 8 and the adjustment bolt 9 on the second mounting plate base 21 enables the worker to adjust the height of the two pressing strips 23, so as to improve the deburring effect on the amorphous strip.

[0047] Referring toFigure 1 , Figure 2 and Figure 3 , the grain removing device 3 includes a first mounting plate base 31 which is vertical and bolted to the cabinet 51 at the bottom. On the side of the first mounting plate base 31 opposite to the amorphous strip, a bearing bar 7 parallel to the width direction of the amorphous strip is also arranged. The bearing bar 7 is installed on the first mounting plate base 31 through the same structure as the adjusting groove 8 and the adjusting bolt 9 in the deburring device 2, and the height of the bearing bar 7 can also be adjusted up and down.

[0048] Refer to Figure 1 , Figure 2 and Figure 4 , a sliding seat 37 is bolted to the bearing bar 7 corresponding to the grain removing device 3. A sliding groove 371 is formed on the upper surface of the sliding seat 37 along the width direction of the amorphous strip, and the sliding seat 37 is in sliding fit with the sliding groove 371.

[0049] Two guiding bars 6 which are both parallel to the width direction of the amorphous strip are bolted to the position of the sliding seat 37 relative to the bottom wall of the sliding groove 371, and there is a distance between the two guiding bars 6. A guiding groove 322 is formed at the bottom of the base 32, and the base 32 slides on the two guiding bars 6 through the guiding groove 322. The sliding fit between the guiding bar 6 and the guiding groove 322 plays a guiding role in adjusting the position of the base 32.

[0050] The longitudinal section of the guiding groove 322 is arranged in a dovetail shape, and the longitudinal section of the guiding bar 6 is arranged in a right trapezoid shape, and the side wall corresponding to the hypotenuse of the right trapezoid is closely attached to the side wall of the guiding groove 322. The setting of the specific cross-sections of the above guiding groove 322 and guiding bar 6 limits the sliding fit between the base 32 and the sliding seat 37, reducing the possibility of the base 32 accidentally disengaging from the sliding seat 37.

[0051] Refer to Figure 1 , Figure 2 and Figure 4 , a rotating stud head 39 which extends into the sliding groove 371 and is located between the two guiding bars 6 is threadedly connected to the sliding seat 37. A connecting column 38 is fixedly arranged at one end of the rotating stud head 39 located in the sliding groove 371. A rotating hole 321 for the connecting column 38 to rotate is formed on the base 32. A sealing plate 40 for closing the rotating hole 321 is slidably and rotatably sleeved on the rotating stud head 39, and the sealing plate 40 is bolted to the base 32.

[0052] Refer to Figure 1 , Figure 2 and Figure 4 , according to the width of the amorphous strip, the worker manually twists the rotating stud head 39, and the rotating stud head 39 drives the connecting column 38 to rotate in the rotating hole 321. In this way, the base 32 can move along the width direction of the amorphous strip, and further adjust the bearing position of the base 32 on the amorphous strip.

[0053] Refer to Figure 1 ,Figure 2 and Figure 4 , at a position above the base 32, the first mounting plate base 31 is bolted with a horizontal bearing plate 33. A cylinder 34 is bolted to the top of the bearing plate 33. The piston rod of the cylinder 34 passes downward through the bearing plate 33 and is threadedly connected with a pressing plate 35 for pressing the amorphous ribbon onto the base 32. A felt layer 36 is adhered to the lower surface of the pressing plate 35.

[0054] Refer to Figure 1 , Figure 2 and Figure 4 , the texture of the felt layer 36 is relatively delicate. Therefore, when the amorphous ribbon passes between the pressing plate 35 and the base 32, the felt layer 36 can wipe off particulate impurities such as dust and powder attached to the amorphous ribbon, thereby improving the purity of the amorphous magnetic ring and being beneficial to improving the use effect of the amorphous magnetic ring.

[0055] Refer to Figure 1 , Figure 2 and Figure 4 , in addition, the pressing action of the pressing plate 35 on the amorphous ribbon can play a certain role in tensioning the amorphous ribbon between it and the winding device 5, thereby improving the winding tightness of the amorphous ribbon.

[0056] Refer to Figure 1 , Figure 2 and Figure 4 , the use of the cylinder 34 must be coordinated with an air pump. In the air path where the cylinder 34 is connected to the air pump in this application, a pressure gauge is also provided. Workers can understand the magnitude of the pressure of the pressing plate 35 on the amorphous ribbon through the pressure gauge, reducing the possibility that the amorphous ribbon is torn due to excessive pressure.

[0057] Refer to Figure 1 , Figure 2 and Figure 4 , the pressing plate 35 is arranged in an L shape and is in close contact with the first mounting plate base 31. The close contact between the pressing plate 35 and the first mounting plate base 31 can play a guiding role in the lifting movement of the pressing plate 35.

[0058] The implementation principle of an amorphous magnetic ring precision winding device in an embodiment of this application is as follows:

[0059] The unwinding device 1 unwinds the amorphous ribbon of the small-sized amorphous magnetic ring, and the amorphous ribbon is adsorbed by the magnetic roller 12, thereby driving the magnetic roller 12 to rotate on the bearing rod 11. After that, it bypasses the guiding roller 13 and passes between the two pressure bars 23. The two pressure bars 23 cooperate to straighten and deburr the amorphous ribbon, and preliminarily intercept impurities such as dust and powder. Next, the amorphous ribbon passes between the felt layer 36 and the base 32. Since the felt layer 36 is relatively delicate, it can wipe off dust and powder and other fine particles attached to the amorphous ribbon. Finally, the amorphous ribbon is wound by the winding device 5.

[0060] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
