Description

Technical Field

[0001] This invention belongs to the technical field of winding equipment, specifically relating to a winding device for multiple sets of ultra-fine metal wires and its winding method. Background Technology

[0002] In the process of winding wire, the common winding method is to use the external thread to move the winding axis to control the winding spacing. However, this method is only suitable for applications with a wide winding spacing. Since it is difficult to make the pitch of the external thread controlling the translation very small, it is difficult to control the spacing when winding extremely fine metal wires, which can easily lead to uneven winding and a large winding spacing. Summary of the Invention

[0003] The purpose of this invention is to provide a winding device and method for winding multiple sets of ultra-fine metal wires in order to solve the above-mentioned problems.

[0004] A multi-set ultra-fine metal wire winding device is used to wind folded fine metal wires. It includes a main frame, an internal thread block disposed on the main frame, and a winding shaft passing through the internal thread block. The surface of the winding shaft is provided with an external thread corresponding to the internal thread block. A locking part for locking the winding carrier is provided at the center of the end of the winding shaft. The main frame is also provided with a wire distributor for equidistantly arranging the fine metal wires. The winding device also includes a counterweight hook for hooking the folded part of the fine metal wire.

[0005] As a further optimization of the present invention, a handle is provided at the end of the winding shaft away from the winding carrier, and the handle is provided to improve the rotation efficiency of the winding shaft.

[0006] As a further optimization of the present invention, the wire divider is fixed to the upper surface of the main frame by a fixing seat, and the surface of the wire divider is provided with equally spaced wire dividing grooves. The entrance of each wire dividing groove is provided with a chamfer. The pitch of the external thread is D, and the distance between adjacent wire dividing grooves is d, where D = 2Nd, and N is the number of metal wire groups. The wire dividing grooves are provided to control the spacing of the fine metal wires before winding, so that the spacing between the multiple strands of metal wires after winding is uniform.

[0007] As a further optimization of the present invention, the internal thread block is an openable combination block, which makes it convenient for the external thread to quickly return after running to the shortest point, without the need for a long reverse winding.

[0008] As a further optimization of the present invention, the internal thread block includes two opposing moving blocks. The contact surfaces of the two moving blocks are provided with semi-circular grooves that fit together to form a complete circle. The surface of the semi-circular groove is provided with an internal thread area corresponding to the external thread, wherein the internal thread area is an intermittent thread. The surface of the main frame is provided with two sliding grooves. The end surface of the moving block is provided with a limiting slider corresponding to the sliding groove. The surface of the main frame is also provided with a driving component for controlling the up and down movement of the moving block. By setting an openable internal thread block, the internal thread block is easy to open and close, easy to drive, and can quickly reset after the internal thread block is disengaged from the external thread.

[0009] As a further optimization of the present invention, the driving component includes a threaded rod rotatably connected to the surface of the main frame, a knob disposed at the end of the threaded rod, and a threaded cylinder corresponding to the threaded rod. One end of the moving block is provided with an inner groove, and a hinge rod is provided between the outer surface of the threaded cylinder and the inner groove wall. A spring is also provided between the two inner grooves. This opening and closing structure is used to drive the inner threaded block to achieve rapid opening and closing, solving the cumbersome problem of external thread rewinding and reset.

[0010] As a further optimization of the present invention, a limit ring is provided at the end of the external thread for positioning during the resetting of the winding shaft.

[0011] To implement the above-mentioned multi-set ultra-fine metal wire winding device, the present invention also proposes a winding method for multi-set ultra-fine metal wires, comprising the following steps:

[0012] S1: Fold N groups of thin metal wires in half along their midpoints to produce 2N ends. Then fix the 2N ends of the folded thin metal wires to the ends of the winding carrier in sequence.

[0013] S2: Place the thin metal wires side by side into the dividing groove, and then hook the counterweight hook into the fold of the thin metal wires;

[0014] S3: Rotate the handle to make the winding shaft rotate. The winding shaft moves laterally through the action of the internal thread block to wind multiple sets of fine metal wires.

[0015] As a further optimization of the present invention, in step S1, the fine metal wire is fixed to the winding carrier by welding, groove fixing, or pressing.

[0016] As a further optimization of the present invention, N sets of the fine metal wires are wound, and for each thread of the external thread, a pitch unit D is given. 2N strands of fine metal wire are wound, and the total spacing of the fine metal wires is 2Nd, where D = 2Nd.

[0017] The beneficial effects of this invention are as follows:

[0018] This invention involves folding a fine metal wire in half and winding it in multiple parallel groups. This winding method is suitable for extremely fine metal wires and has low requirements for thread precision. The device only needs to control the spacing of the dividing grooves during manufacturing, resulting in low process complexity and low cost. It can evenly wind extremely fine metal wires onto the surface of the winding carrier. Attached Figure Description

[0026] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0027] Example 1

[0028] like Figure 1-6As shown, a multi-set ultra-fine metal wire winding device is used to wind a folded fine metal wire 11. It includes a main frame 1, an internal thread block 5 disposed on the main frame 1, and a winding shaft 6 passing through the internal thread block 5. The surface of the winding shaft 6 is provided with an external thread 61 corresponding to the internal thread block 5. A locking part for locking the winding carrier 9 is provided at the center of the end of the winding shaft 6. The main frame 1 is also provided with a wire separator 8 for equidistantly arranging the fine metal wires 11. The winding device also includes a counterweight hook 2 for hooking the folded part of the fine metal wire 11.

[0029] The splitter 8 is fixed to the surface of the main frame 1 by the fixing base 7, and the surface of the splitter 8 is provided with equally spaced splitting grooves 81, and the entrance of each splitting groove 81 is provided with a chamfer 82.

[0030] In use, the fine metal wires 11 are wound in parallel. When the external thread 61 advances one thread unit, the fine metal wires 11 are wound in parallel for one turn. Each group of fine metal wires 11 is folded in half and a counterweight hook 12 is used to hook the folded part, so that each group of fine metal wires 11 is in a taut state. When the fine metal wires 11 are about to be wound on the surface of the winding carrier 9, they are first separated by the wire divider 8 to prevent tangling. At the same time, the wire divider 8 is provided with equidistant wire dividing grooves 81 to make the spacing of the fine metal wires 11 equal.

[0031] like Figure 6 The diagram shows the winding process of two sets of fine metal wires 11. The winding spacing on the surface of the winding carrier 9 is d, the spacing of each branching groove 81 in the distributor 8 is d, and the winding carrier 9 is wound for a length of D for each pitch unit D of the external thread 61. For each turn of winding, four metal wires are wound on the surface of the winding carrier 9, i.e., D = 4d. The multiple winding method allows even the fine metal wires to be wound uniformly.

[0032] It should be noted that when adjusting the winding spacing d, the corresponding splitter 8 and the corresponding external thread 61 need to be replaced first. If N groups of fine metal wires 11 are wound, where N is an integer greater than 1, then for each pitch unit D of the external thread 61, the fine metal wires 11 are wound with 2N strands, and the total spacing of the fine metal wires 11 is 2Nd, that is, D = 2Nd.

[0033] In actual use, after completing a winding task, the winding shaft 6 needs to be reversed and reset, that is, it needs to be reversed along the external thread 61 back to the starting point. In order to facilitate the reset, the internal thread block 5 is set as an open and close combination block.

[0034] The internal thread block 5 includes two opposing moving blocks 51. The contact surfaces of the two moving blocks 51 are provided with semi-circular grooves 53 that fit together to form a complete circle. The inner wall of the semi-circular groove 53 is provided with an internal thread area 54 corresponding to the external thread 61. The internal thread area 54 is an intermittent thread. The surface of the main frame 1 is provided with two sliding grooves 31. The end surface of the moving block 51 is provided with a limiting slider 52 corresponding to the sliding groove 31. The surface of the main frame 1 is also provided with a driving component for controlling the up and down movement of the moving block 51.

[0035] When the moving blocks 51 move away from each other, the semicircular grooves 53 open, and the internal thread area 54 disengages from the external thread 61, so that the winding shaft 6 can return without rotation. The internal thread areas 54 of the upper and lower semicircular grooves 53 are intermittent threads to facilitate disengagement. Without affecting the winding, the moving blocks 51 only need to open a small distance to allow the winding shaft 6 to move back and forth.

[0036] The driving component includes a threaded rod 58 rotatably connected to the surface of the main frame 1, a knob 57 located at the end of the threaded rod 58, and a threaded cylinder 59 corresponding to the threaded rod 58. One end of the moving block 51 is provided with an inner groove 55. A hinge rod 510 is provided between the outer surface of the threaded cylinder 59 and the surface wall of the inner groove 55. A spring 56 is also provided between the two inner grooves 55.

[0037] In use, rotating the knob 57 moves the threaded cylinder 59 away from the knob 57. Under the push of the spring 56, the two moving blocks 51 separate from each other. Conversely, rotating the knob 57 in the opposite direction pulls the two moving blocks 51 to close through the hinge rod 510. The knob 57 has a small rotation range, making operation convenient and quick.

[0038] The end of the winding shaft 6 is provided with a handle 4 for easy rotation, and the surface of the main frame 1 is provided with a limiting block 3 for limiting the winding shaft 6.

[0039] To facilitate positioning when the winding shaft 6 returns, a limit ring 62 is provided at the end of the external thread 61.

[0040] After the thin metal wire 11 is hung on the counterweight hook 2, in order to prevent the thin metal wire 11 from swinging and getting tangled, a guide plate 10 is provided on the surface of the main frame 1 to guide and separate the thin metal wire 11.

[0041] To implement the above-mentioned multi-set ultra-fine metal wire winding device, the present invention also proposes a winding method for multi-set ultra-fine metal wires, comprising the following steps:

[0042] S1: Fold N groups of fine metal wires in half along their midpoints to produce 2N ends. Then, fix the 2N ends of the folded fine metal wires to the ends of the winding carrier in sequence. The fixing methods include welding, groove fixing, and pressing fixing.

[0043] S2: Place the thin metal wires side by side into the dividing groove, and then hook the counterweight hook into the fold of the thin metal wires;

[0044] S3: Rotate the handle to make the winding shaft rotate. The winding shaft moves laterally through the action of the internal thread block to wind multiple sets of fine metal wires.

[0045] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
