Description

Technical Field

[0001] This utility model relates to the field of amorphous ribbon winding technology, and in particular to an automatic winding device for amorphous ribbon. Background Technology

[0002] Amorphous ribbons generally refer to solid thin ribbons of a certain thickness formed by rapidly cooling liquid metal, resulting in an amorphous alloy structure with short-range order and long-range disorder in atomic arrangement. They possess excellent magnetic properties, corrosion resistance, wear resistance, high hardness, high strength, and high resistivity, and are widely used in fields such as electronics, aviation, aerospace, machinery, and microelectronics.

[0003] Amorphous ribbons are extremely thin and brittle, making them prone to breakage. Therefore, multiple rolls of ribbon need to be combined into a single roll to withstand high-strength processing steps such as stamping and lamination. During the coiling process, the ribbon is prone to deviation from its original position as it moves from the unwinding device to the rewinding device, leading to inconsistent rewinding quality.

[0025] Both the winding device 1 and the unwinding device 2 are equipped with a spool 6 for detachably connecting the roll 5, and a winding / unwinding motor 7 for driving the spool 6 to rotate around the axis of the spool 6; the amorphous strip is wound on the roll 5.

[0026] The winding device 1 or the unwinding device 2 is connected to the sliding device, or the winding device 1 and the unwinding device 2 are connected to different sliding devices. The sliding device is used to drive the winding device 1 or the unwinding device 2 to move in a direction parallel to the axis of the roll 6. The sliding device is electrically connected to the detection device 4.

[0027] After the detection device 4 detects that the strip is off-center, the sliding device drives the winding device 1 or the unwinding device 2 to move, so as to adjust the position of the strip on the tensioning device 3, thereby correcting the deviation and improving the winding quality.

[0028] Furthermore, the reel 6 has an expansion and contraction structure. When the expansion and contraction structure is tightened inside the drum 5, the drum 5 is mounted on the reel 6. At this time, when the expansion and contraction structure contracts towards the axis of the reel 6, the drum 5 can be detached from the reel 6. The principle of the expansion and contraction structure is the same as that of the hydraulic / mechanical spring expansion and contraction structure in CN103170589A or the opening and closing principle of the machine tool chuck, and will not be elaborated further here.

[0029] Furthermore, multiple unwinding devices 2 are provided. After the strip material on one unwinding device 2 is consumed, other unwinding devices 2 loaded with strip material can quickly take over the unwinding operation to reduce the impact of unwinding device 2 disassembling and assembling the roll 5 on the winding efficiency and improve the winding efficiency.

[0030] Furthermore, the tensioning device 3 includes multiple rollers, and the strip output from the unwinding device 2 is wound around all the rollers in sequence and then wound up by the winding device 1. The relative positions between the different rollers are adjustable to achieve dynamic adjustment of the strip tension.

[0031] In some embodiments, the detection device 4 is disposed between the tensioning device 3 and the winding device 1 to further improve the winding quality and reduce the possibility of secondary deviation of the strip after correction.

[0032] In some embodiments, the winding device 1 and the unwinding device 2 are connected to different sliding devices, and each unwinding device 2 is connected to a sliding device, so that the winding device 1 and each unwinding device 2 can move relatively independently under the drive of their respective corresponding sliding devices, so as to further improve the correction efficiency.

[0033] In some embodiments, the sliding device connected to the unwinding device 2 is a first sliding device, which includes a first mounting base 81 and a linear drive device 82; the unwinding device 2 is slidably connected to the first mounting base 81, the linear drive device 82 is connected to the first mounting base 81, and the output end of the linear drive device 82 is connected to the unwinding device 2.

[0036] In some embodiments, the first sliding device further includes a plurality of parallel slide rails 83 detachably connected to the first mounting base 81; the unwinding device 2 is provided with slide grooves corresponding one-to-one with the slide rails 83, each slide groove slidingly engaging with its corresponding slide rail 83. The plurality of slide rails 83 can improve the limiting effect on the movement direction of the unwinding device 2, and the detachable configuration of the slide rails 83 also facilitates the extension of the service life of the sliding device by replacing the slide rails 83.

[0037] Furthermore, two slide rails 83 are provided.

[0038] Furthermore, the slide rail 83 is located on the top surface of the first mounting base 81, so as to improve the reliability of the sliding fit between the slide rail 83 and the unwinding device 2 by means of the weight of the unwinding device 2 itself.

[0039] In some embodiments, the sliding device connected to the winding device 1 is a second sliding device, which includes: a second mounting base 91, a lead screw, and a drive motor 92; the lead screw passes through the winding device 1 and is threadedly engaged with the winding device 1, the winding device 1 is slidably engaged with the second mounting base 91, both ends of the lead screw are rotatably connected to the second mounting base 91, and the output end of the drive motor 92 is connected to the end of the lead screw. The rotation of the lead screw drives the winding device 1 to slide on the second mounting base 91. The drive motor 92 and the lead screw enable high-precision control of the displacement of the winding device 1, further improving the correction effect.

[0040] In some embodiments, the drive motor 92 is a servo motor to further improve the control accuracy of the displacement adjustment of the winding device 1.

[0041] In some embodiments, the unwinding device 2 further includes a guide roller 21, which is located on the side of the unwinding device 2's roll 6 near the winding device 1. The axis of the guide roller 21 is parallel to the axis of the roll 6. The strip on the roll 6 of the unwinding device 2 passes sequentially through the guide roller 21 and the tensioning device 3 before being wound up by the winding device 1. The guide roller 21 reduces the impact of the correction action on the position of the strip on the roll 6 in the unwinding device 2.

[0042] In some embodiments, when there are multiple unwinding devices 2, all unwinding devices 2 are arranged longitudinally; tensioning devices 3 correspond one-to-one with unwinding devices 2, and each tensioning device 3 is used to tension the strip output by the corresponding unwinding device 2.

[0044] 2. Multiple unwinding devices 2 are provided. After the strip material on one unwinding device 2 is consumed, other unwinding devices 2 loaded with strip material can quickly take over the unwinding operation to reduce the impact of unwinding device 2 disassembling and assembling the roll 5 on the winding efficiency and improve the winding efficiency.
