For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0029] The following Figures 1 to 3 is combined to describe a mechanism for wrapping insulating paper according to an embodiment of the present utility model.

[0030] A mechanism for wrapping insulating paper includes a magnetic core clamping device 431, a first magnetic core auxiliary pressing device 432, and a second magnetic core auxiliary pressing device 433.

[0031] The magnetic core clamping device 431 is provided with a space for clamping the magnetic core. The first magnetic core auxiliary pressing device 432 and the second magnetic core auxiliary pressing device 433 are both located on the front side of the magnetic core clamping device 431. The pressing end of the first magnetic core auxiliary pressing device 432 is located above the center of the space for clamping the magnetic core, and the pressing end of the second magnetic core auxiliary pressing device 433 is located above the two ends of the space for clamping the magnetic core.

[0032] The magnetic core clamping device 431 is used for clamping and rotating the magnetic core. The first magnetic core auxiliary pressing device 432 is used for pressing the middle part of the magnetic core, and the second magnetic core auxiliary pressing device 433 is used for pressing the two ends of the magnetic core.

[0033] The first magnetic core auxiliary pressing device 432 is accurately positioned above the middle part of the magnetic core, ensuring the tight fit of the insulating paper in the central area of the magnetic core and effectively preventing the problem of central voids caused by uneven paper tension or improper operation. At the same time, the second magnetic core auxiliary pressing device 433 covers the upper parts of the two ends of the magnetic core, further compressing the wrinkles and voids of the insulating paper at the two ends of the magnetic core, making the entire wrapping process more uniform and compact.

[0034] Traditional processes for insulating paper wrapping around magnetic cores often rely on the experience and skills of operators, resulting in significant uncertainties and cost fluctuations. However, through automated or semi-automated designs, this mechanism can stably and efficiently control the process of wrapping insulating paper, reducing production interruptions and time waste caused by gap adjustment, re-wrapping, etc., lowering the requirements for operator skills, and also reducing material waste and rework costs caused by improper operations.

[0035] The magnetic core clamping device 431 includes a rotating component 4311, a first clamping member 4312, and a second clamping member 4313. The first clamping member 4312 and the second clamping member 4313 approach each other and clamp the magnetic core.

[0036] The rotating component 4311 includes a rotating motor 4314, a rotating shaft 4315, a first rotating belt 4316, and a second rotating belt 4317. The driving end of the rotating motor 4314 is fixedly connected to the rotating shaft 4315. The rotating shaft 4315 is located below the first clamping member 4312 and the second clamping member 4313. The length direction of the rotating shaft 4315 is the connection direction of the first clamping member 4312 and the second clamping member 4313. The first rotating belt 4316 is sleeved on one end of the first clamping member 4312 and the rotating shaft 4315, and the second rotating belt 4317 is sleeved on the other end of the second clamping member 4313 and the rotating shaft 4315.

[0037] First, start the rotating motor 4314. The driving end of the motor drives the rotating shaft 4315 to rotate. The rotating shaft 4315 serves as the central axis, and its length direction is exactly the same as the connection direction of the first clamping member 4312 and the second clamping member 4313, ensuring that the first clamping member 4312 and the second clamping member 4313 can rotate synchronously around the same axis.

[0038] As the rotating shaft 4315 rotates, the first rotating belt 4316 and the second rotating belt 4317 sleeved on both ends of the rotating shaft 4315 also rotate. The first clamping member 4312 and the second clamping member 4313 respectively rotate around the rotating shaft 4315 under the traction of the first rotating belt 4316 and the second rotating belt 4317.

[0039] While the first clamping member 4312 and the second clamping member 4313 are rotating, they approach each other and tightly clamp the magnetic core. The magnetic core, under the stable clamping of the first clamping member 4312 and the second clamping member 4313, rotates synchronously with the rotation of the first clamping member 4312 and the second clamping member 4313, enabling the magnetic core to maintain a stable posture and position during the processing, facilitating the subsequent smooth wrapping of insulating paper and tape.

[0040] The first magnetic core auxiliary pressing device 432 includes a magnetic core pressing horizontal power component 4321, a magnetic core pressing slider 4322, a magnetic core auxiliary pressing component 4323, a magnetic core pressing vertical power component 4324, and a magnetic core auxiliary pressing roller;

[0041] The installation end of the magnetic core pressing horizontal power component 4321 is installed on the frame 1. The driving end of the magnetic core pressing horizontal power component 4321 is fixedly installed with the magnetic core pressing slider 4322. The driving end of the magnetic core pressing horizontal power component 4321 faces the space for clamping the magnetic core. The magnetic core pressing slider 4322 is fixedly installed with the magnetic core pressing vertical power component 4324. The driving end of the magnetic core pressing vertical power component 4324 is fixedly connected to the magnetic core auxiliary pressing component 4323. The pressing end of the magnetic core auxiliary pressing component 4323 is rotatably installed with the magnetic core auxiliary pressing roller.

[0042] It should be noted that the magnetic core pressing horizontal power component 4321 is preferably a cylinder, and the magnetic core pressing vertical power component 4324 is preferably a cylinder. By using the magnetic core pressing horizontal power component 4321, the device can accurately adjust its position in the horizontal direction, ensuring that the magnetic core auxiliary pressing component 4323 can accurately align with the magnetic core to be processed, which is crucial for improving the automation level of the production line and reducing the error of manual intervention. At the same time, the introduction of the magnetic core pressing vertical power component 4324 enables flexible height adjustment of the magnetic core auxiliary pressing component 4323 and the magnetic core auxiliary pressing roller in the vertical direction, further enhancing the adaptability and flexibility of a kind of insulating paper wrapping mechanism, ensuring that the magnetic core auxiliary pressing roller can just press on the predetermined position of the magnetic core to achieve precise pressing.

[0043] Compared with the traditional planar pressing method, the design of the magnetic core auxiliary pressing roller significantly reduces the contact area, thereby reducing the friction and wear caused by direct contact, protecting the surface of the magnetic core from damage. In addition, the roller-shaped pressing can better adapt to the minor unevenness of the magnetic core surface, achieving a more uniform and stable pressing force and improving the processing quality.

[0044] The magnetic core auxiliary pressing component 4323 is of an arc-shaped structure.

[0045] The arc-shaped magnetic core auxiliary pressing component 4323 can naturally fit the edge of the magnetic core, effectively avoiding the direct collision or interference between the magnetic core auxiliary pressing component 4323 and the magnetic core surface during the process of wrapping the insulating paper. This not only protects the magnetic core from damage but also reduces the noise and vibration caused by improper contact, improving the overall working stability and reliability. At the same time, the arc-shaped structure also enables materials such as insulating paper to be more smoothly wrapped around the magnetic core during the pressing process, reducing quality problems caused by material accumulation or wrinkles.

[0046] The magnetic core auxiliary pressing member 4323 with an arc-shaped structure has stronger adaptability and can be applied to magnetic cores of various shapes and sizes. Whether it is a cylindrical, square or other irregular-shaped magnetic core, the arc-shaped pressing member can achieve accurate and stable pressing effects by adjusting its position and angle. This wide range of applicability greatly expands the usage scope of the equipment, enabling the same set of equipment to handle diversified production requirements and enhancing the flexibility and efficiency of the production line.

[0047] The second magnetic core auxiliary pressing device includes two silicone auxiliary pressing members 4331, and an activity space of the first magnetic core auxiliary pressing device 432 is formed between the two silicone auxiliary pressing members 4331.

[0048] As a highly elastic material, silicone has good buffering and shock-absorbing characteristics. When the magnetic core is subjected to external impacts during the process of wrapping insulating paper, the silicone auxiliary pressing member 4331 can effectively absorb these impact energies, reduce vibrations and noises, protect the magnetic core and surrounding components from damage, and thus extend the service life of the entire system.

[0049] When the magnetic core auxiliary pressing roller and the silicone auxiliary pressing member 4331 act together, they form an efficient and accurate pressing mechanism. The magnetic core auxiliary pressing roller provides stable mechanical pressure, while the silicone auxiliary pressing member 4331 evenly transfers this pressure between the insulating paper and the magnetic core through its elastic deformation ability, ensuring a tight fit between the two, improving the efficiency of wrapping insulating paper, significantly enhancing the finished product quality of assembling the magnetic core, and ensuring the stability and reliability of the magnetic core during operation.

[0050] The silicone auxiliary pressing member 4331 is provided with a circular clearance groove.

[0051] The design of the circular clearance groove enables the silicone auxiliary pressing member 4331 to more flexibly adapt to the shape and contour of the magnetic core surface when pressing the magnetic core. The existence of the circular clearance groove reduces the direct contact area between the silicone and the magnetic core surface, thereby reducing the stress concentration caused by shape mismatch and the risk of damage to the magnetic core and the silicone itself. This design is particularly suitable for magnetic cores with complex shapes or uneven surfaces, improving the assembly compatibility and success rate.

[0052] When the silicone auxiliary pressing member 4331 is subjected to an external force, the clearance groove can serve as a stress release point, enabling the pressure to be more evenly distributed between the magnetic core and the insulating paper. This uniform pressure distribution helps to achieve a tighter fit effect, reducing voids and wrinkles caused by excessive or insufficient local pressure.

[0053] The second magnetic core auxiliary pressing device also includes a second magnetic core auxiliary lifting power component 4332, which is vertically installed on the frame 1, and the driving end of the second magnetic core auxiliary lifting power component 4332 is fixedly connected to the silicone auxiliary pressing component 4331.

[0054] The introduction of the second core-assisting lifting element 4332 enables precise vertical height adjustment of the silicone auxiliary pressing element 4331. This function is crucial for ensuring that the silicone auxiliary pressing element 4331 accurately and stably presses against the magnetic core. By precisely controlling the output of the lifting element, the contact force between the silicone auxiliary pressing element 4331 and the magnetic core is ensured to be moderate, neither too tight to cause damage nor too loose to affect the fit.

[0055] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific implementations of the present invention without inventive effort, and such implementations will fall within the scope of protection of the present invention.
