Description

Technical Field

[0001] This application relates to the field of coil winding equipment, and more specifically, to a skeleton clamping structure and its coil winding device. Background Art

[0002] A coil winding machine is a machine that can wind copper wires around a skeleton. In an inductance coil winding machine, due to the small structure of the wound skeleton, strict requirements are imposed on the clamping structure of the skeleton: the structure of the skeleton cannot be damaged while ensuring the completion of winding. In the existing inductance coil winding, a robotic arm is often used to clamp the skeleton, and the robotic arm clamps the skeleton from the left and right sides of the skeleton. When the flying fork winding process is used for winding, the copper wire is guided by the flying fork and wound around the skeleton in circles. During this process, since the skeleton has been subjected to the clamping force of the robotic arm in the horizontal direction, and the skeleton is also subjected to the pulling force of the flying fork around it, this will cause uneven stress on the skeleton, resulting in a decrease in the progress of the copper wire laying, and it will also damage the copper wire. Seriously, it will also damage the skeleton. Summary of the Invention

[0023] The following will describe the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application.

[0024] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of the present application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0025] Please refer to Figures 1 to 4In a first aspect of an embodiment of the present application, a skeleton clamping structure 1 is provided, which is used to clamp a skeleton 7 and is suitable for a coil winding device, such as an inductor coil winding device. The skeleton clamping structure 1 includes a rotating shaft 2, a base 3, a first clamping block 4 and a second clamping block 5. The rotating shaft 2 extends outward from the base 3 along the axial direction, and the base 3 can be a flat plate. The base 3 can be formed integrally with the rotating shaft 2. The first clamping block 4 is detachably connected to the base 3, and the second clamping block 5 can be rotatably connected to the base 3 and move closer to or away from the first clamping block 4. The end of the first clamping block 4 away from the rotating shaft 2 forms a first clamping portion 41, and the end of the second clamping block 5 away from the rotating shaft 2 forms a second clamping portion 51. The first clamping portion 41 and the second clamping portion 51 form a clamping space 6. If the first clamping portion 41 can be a "匚" type opening to the left, and the second clamping portion 51 can be a "匚" type opening to the right, the clamping space 6 can be formed into a "口"-shaped rectangle. The clamping space 6 matches the shape of the skeleton 7. The shape of the skeleton 7 can be rectangular, polygonal, circular, etc., and the clamping space 6 can be correspondingly rectangular, polygonal, circular, etc. The clamping space 6 matches the shape of the skeleton 7, providing a uniform force-bearing area for the skeleton 7, and protecting the structural integrity of the skeleton 7 during the winding process.

[0026] Please refer to Figure 3 In order to improve the adaptability and applicability of the skeleton clamping structure 1, the first clamping block 4 includes a first upper clamping piece 42 and a first lower clamping piece 43. The first upper clamping piece 42 and the first lower clamping piece 43 are stacked on the base 3. The first upper clamping piece 42 and the first lower clamping piece 43 form a first clamping portion 41 at one end away from the rotating shaft 2. If the first clamping portion 41 is a "匚" type opening to the left, the first upper clamping piece 42 corresponds to a "┐" type, and the first lower clamping piece 43 corresponds to a "┘" type. Similarly, the second clamping block 5 includes a second upper clamping piece 52 and a second lower clamping piece 53, which are stacked on the base 3 and correspond to the first upper clamping piece 42 and the first lower clamping piece 43. The second upper clamping piece 52 and the second lower clamping piece 53 form a second clamping portion 51 at one end away from the rotating shaft 2. If the second clamping portion 51 is a "匚" type opening to the right, the second upper clamping piece 52 corresponds to a "┌" type, and the second lower clamping piece 53 corresponds to a "└". The combination form can expand the clamping range and application range of the first clamping block 4 and the second clamping block 5.

[0027] Please refer to Figure 2 In a general embodiment, the first upper clamping piece 42 matches the first lower clamping piece 43 in shape, and the second upper clamping piece 52 matches the second lower clamping piece 53 in shape.

[0028] In a general embodiment, an elastic element 8 is further included, and the elastic element 8 can be a clip-opening spring. One end of the first clamping block 4 close to the rotating shaft 2 forms a first abutting portion 44, and one end of the second clamping block 5 close to the rotating shaft 2 forms a second abutting portion 54. The first abutting portion 44 and the second abutting portion 54 are arranged at intervals. The elastic element 8 is press-fitted between the first abutting portion 44 and the second abutting portion 54, so that the elastic element 8 can continuously expand the distance between the first abutting portion 44 and the second abutting portion 54 to reach the maximum defined distance. Taking the middle part of the second clamping block 5 as the rotation point, the second clamping portion 51 of the second clamping block 5 can stably provide a clamping force to the clamping space 6 to clamp the skeleton 7.

[0029] Please refer to Figure 2 , in a general embodiment, a slope 9 is formed on one side of the first clamping block 4 close to the second clamping block 5. The slope 9 has a tendency to gradually move away from the second clamping block 5 between the first clamping portion 41 and the first abutting portion 44. The first clamping block 4 can be trapezoidal, and the second clamping block 5 can be rectangular. The gap between the first clamping block 4 and the second clamping block 5 serves as the activity space for the rotation of the second clamping block 5.

[0030] In a general embodiment, a rotating pin shaft 19 is further included. The rotating pin shaft 19 sequentially passes through the middle part of the second clamping block 5 and the base 3 and is fixedly connected to the base 3. The rotating pin shaft 19 serves as the rotation point of the second clamping block 5, and the second clamping block 5 can rotatably form or separate the clamping space 6.

[0031] Please refer to Figure 2 , in a general embodiment, in order to prevent impurities from falling into the activity space where the second clamping block 5 rotates during the working process and hinder the rotation of the second clamping block 5, the skeleton clamping structure 1 further includes a positioning pin shaft 10 and a limiting piece 11. The limiting piece 11 covers the first clamping block 4 and the second clamping block 5 and covers the activity space of the second clamping block 5. The first clamping block 4 and the second clamping block 5 are clamped between the limiting piece 11 and the base 3. The positioning pin shaft 10 sequentially passes through the limiting piece 11, the first clamping block 4, and the base 3 and is fixedly connected to the base 3.

[0032] Please refer to Figure 1 , in a general embodiment, a fixed bracket 12, a first wire winding bracket 13, and a second wire winding bracket 14 are further included. The rotating shaft 2 is sleeved in the fixed bracket 12 and exposed from the base 3. The rotating shaft 2 drives the base 3 to rotate relative to the fixed bracket 12. The fixed bracket 12 can be a frame-shaped structure. The first wire winding bracket 13 is connected to the fixed bracket 12, and the second wire winding bracket 14 is connected to the base 3. When the rotating shaft 2 drives the base 3 to rotate, the second wire winding bracket 14 rotates with the base 3. The first wire winding bracket 13 and the second wire winding bracket 14 form a combined structure similar to a "U" shape. The copper wire 18 is wound around the skeleton 7 under the guidance of the first wire winding bracket 13 and the second wire winding bracket 14 to form a coil.

[0033] In a general embodiment, it further includes a wire winding pin shaft 15. The wire winding pin shaft 15 passes through the first clamping block 4 and the base 3 and is connected to the base 3, and is exposed on the first clamping block 4. The copper wire 18 can pass through the wire winding pin shaft 15 and then be wound around the skeleton 7.

[0034] Please refer to Figure 4 , in a second aspect, an embodiment of the present application provides a coil winding device, which includes the above-mentioned skeleton clamping structure 1, a working turntable 16, and a driving main shaft (not shown in the figure). A plurality of skeleton clamping structures 1 are arranged around the working turntable 16, and the skeleton clamping structure 1 can be installed according to work requirements. The driving main shaft is movably connected to the rotating shaft 2 through a coupling 17, and multiple skeleton clamping structures 1 can be started simultaneously to perform coil winding work. At the same time, since the driving main shaft rotates, compared with the rotation of the guiding needle in the traditional flying fork winding, since the copper wire 18 has no obvious fold angle, in a natural state, it can ensure that the winding needle and the copper wire 18 are perpendicular to the winding surface of the skeleton 7, which can effectively prevent damage to the copper wire 18 caused by the fold angle and unstable wire arrangement.

[0035] An embodiment of the present application provides a skeleton clamping structure 1 and its coil winding device. Through the clamping space 6 formed by the combination of the first clamping block 4 and the second clamping block 5, the clamping space 6 matches the shape of the skeleton 7, providing a uniform stress area for the skeleton 7. Compared with the existing coil winding machines, the skeleton clamping structure 1 and its coil winding device provided by the embodiment of the present application protect the integrity of the skeleton 7 structure while improving the wire arrangement accuracy of the copper wire 18 and not damaging the copper wire 18.

[0036] In several embodiments provided by the present application, it should be understood that the functional modules in each embodiment can be integrated together to form an independent part, or each module can exist alone, or two or more modules can be integrated to form an independent part.
