Description

Technical Field

[0001] This utility model relates to the field of power cable manufacturing, and in particular to a device for fixing irregularly shaped conductors and a processing system. Background Technology

[0002] The sector-shaped conductor structure has several significant advantages in the current cable industry. It features high utilization rate, material cost savings, excellent flexibility and bending performance, achieving a balance between quality and cost, making it the preferred solution in specific application scenarios.

[0003] Due to their irregular shape, fan-shaped conductors are more difficult to process than round conductors. During extrusion, they are prone to mold jamming, core rubbing causing breakage, and uncontrollable eccentricity. Issues such as embedded insulation on the fan edges are also industry challenges. Unlike round conductors on the market, fan-shaped conductors have an irregular structure, and the fan edges tend to protrude, resulting in burrs. When using traditional molds, the protruding conductor burrs, the insulation being squeezed and embedded in the conductor, and the sagging of the insulation fan edges all contribute to irregular insulation extrusion and significant eccentricity. Using custom-designed fan-shaped extrusion molds and sleeves ensures that the insulation is extruded in the same direction as the conductor, resulting in a uniform insulation layer that adheres to the fan-shaped conductor. However, the irregular surface of the fan-shaped conductor leads to significant vibration during production, and the conductor is prone to rubbing against the mold core. Utility Model Content

[0006] The fixing mechanism includes: a base, a first guide wheel and a second guide wheel.

The number of the second guide wheels is at least two and the angle formed between the movement direction of the second guide wheel and the movement direction of the first guide wheel is an obtuse angle. A groove is formed on the circumference of the first guide wheel.

[0007] The drive mechanism is configured in multiple groups and is used to drive the first guide wheel and the second guide wheel respectively.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0027] Example

[0028] Reference Figures 1-5 As shown, the present invention provides a device for fixing irregularly shaped conductors, comprising:

[0029] The fixing mechanism includes: a base 1, a first guide wheel 3 and a second guide wheel 4. The first guide wheel 3 and the second guide wheel 4 are respectively movably disposed on the base 1 radially. The number of the second guide wheels 4 is at least two and the angle formed between the direction of movement of the second guide wheel 4 and the direction of movement of the first guide wheel 3 is an obtuse angle. The circumferential side of the first guide wheel 3 is provided with a groove.

[0030] The drive mechanism is configured in multiple groups to drive the first guide wheel 3 and the second guide wheel 4 respectively. Each drive mechanism includes: a drive component 2, a first gear 10, a second gear 11, a nut sleeve 7, and a lead screw 8. The first gear 10 is fixedly connected to the end of the drive component 2. The nut sleeve 7 is rotatably connected to the base 1. The second gear 11 is coaxially fixedly connected to the nut sleeve 7 and meshes with the first gear 10. The lead screw 8 is adapted to be fitted inside the nut sleeve 7. The first guide wheel 3 or the second guide wheel 4 is rotatably connected to the lead screw 8 respectively.

[0031] The present invention discloses a device for fixing irregularly shaped conductors. A first guide wheel 3 and a second guide wheel 4 are radially movably arranged along a base 1, allowing them to move in a radial direction with the center of the base 1 as the origin. This enables the guide wheels to be adjusted according to the different shapes and positions of the irregularly shaped conductors. A driving component 2 drives a first gear 10 to rotate. Since the first gear 10 meshes with a second gear 11, the second gear 11 rotates accordingly. The second gear 11 is coaxially fixed to a nut sleeve 7, so the nut sleeve 7 also begins to rotate. The internal threads of the nut sleeve 7 cooperate with a lead screw 8. When the nut sleeve 7 rotates, the lead screw 8 moves linearly along the radial direction of the base 1 under the drive of the nut sleeve 7, causing the first guide wheel 3 and the second guide wheel 4 to make close contact with the irregularly shaped conductor from different directions. The groove of the first guide wheel 3 fits into the fitting part of the irregularly shaped conductor, and multiple second guide wheels 4 provide support from other directions, thereby stably fixing the irregularly shaped conductor to the fixing mechanism, completing the fixing operation of the irregularly shaped conductor.

[0032] Reference Figure 2 As shown, the base 1 is an annular base 1, and the fixing mechanism and driving mechanism are arranged around the periphery of the base 1, providing a centrally symmetrical and stable structure. This shape allows the fixing mechanism and driving mechanism to be evenly arranged around its periphery, facilitating the all-round and balanced fixing and adjustment of irregularly shaped conductors. Around the circumference of the annular base 1, multiple sets of guide wheels for fixing irregularly shaped conductors and driving components for driving the guide wheels are distributed at intervals. This allows the irregularly shaped conductors to be fixed and adjusted from multiple different angles within the annular space, greatly improving the adaptability of the device to irregularly shaped conductors of different shapes and sizes.

[0033] Reference Figure 1 , Figure 4As shown, the base 1 has a first through hole 9 extending through its thickness in the radial direction. A bearing 13 is embedded in the first through hole 9. The outer ring of the bearing 13 is fixedly sleeved in the first through hole 9, and the inner ring of the bearing 13 is fixedly sleeved on the outside of the nut sleeve 7. The bearing 13 is tightly embedded in the first through hole 9. The outer ring of the bearing 13 and the first through hole 9 are sleeved in a fixed fit, including but not limited to interference fit, snap-fit, adhesive, threaded connection, etc. This ensures a stable and reliable connection between the outer ring of the bearing 13 and the base 1. The inner ring of the bearing 13 is firmly sleeved on the outside of the nut sleeve 7, allowing the nut sleeve 7 to rotate flexibly with the support of the inner ring of the bearing 13. When the driving component 2 in the driving mechanism drives the first gear 10 to rotate, and then causes the second gear 11 meshing with it to rotate, the nut sleeve 7 will rotate with the support of the inner ring of the bearing 13 because the second gear 11 is coaxially fixed to the nut sleeve 7. During this process, the tight fit between the inner ring of bearing 13 and nut sleeve 7 effectively reduces the frictional resistance between them, ensuring the smoothness and stability of nut sleeve 7's rotation. This greatly reduces frictional loss during nut sleeve 7's rotation, improves the transmission efficiency of the drive mechanism, reduces energy consumption, and extends the service life of the device.

[0034] Reference Figure 3 As shown, the second gear 11 is sleeved on the lead screw 8, and its inner diameter is larger than the outer diameter of the lead screw 8. The second gear 11 is located on the outer side of the annular base 1. This ensures that the second gear 11 and the lead screw 8 are not tightly fitted, but have a certain gap. This avoids interference between the lead screw 8 and the second gear 11 when the lead screw 8 moves linearly along the nut sleeve 7, allowing the lead screw 8 to move smoothly axially without being obstructed by the second gear 11, thus ensuring the stability and smoothness of the drive mechanism transmission. From the perspective of installation and maintenance, placing the second gear 11 on the outside, exposing it to a relatively easily accessible position, greatly facilitates the operation of the second gear 11 during device assembly, debugging, and subsequent maintenance. Whether it is for inspection, cleaning, lubrication, or disassembly and installation when parts need to be replaced, it is more convenient and efficient, reducing maintenance costs and difficulty. From the perspective of overall structural layout, the second gear 11 being located on the outer side of the annular base 1 helps to optimize the utilization of the internal space of the device, avoiding the stacking of too many parts in the limited space inside the annular base 1, making the internal structure more compact and reasonable.

[0035] Reference Figure 5 As shown, the first guide wheel 3 and the second guide wheel 4 are detachably mounted on the lead screw 8. The first end of the lead screw 8 is provided with a limiting part 12, the size of which is larger than the inner diameter of the second gear 11. This allows the guide wheels to be easily disassembled and replaced when they are worn, damaged, or when different specifications of guide wheels need to be replaced due to processing requirements, effectively reducing equipment maintenance costs and improving the versatility of the device.

[0036] Reference Figure 5 As shown, the second end of the lead screw 8 is connected to a plug-in portion 14, and a sleeve 16 is fitted onto the plug-in portion 14. A bracket 6 is fixedly connected to the sleeve 16, and the first guide wheel 3 or the second guide wheel 4 is rotatably connected to the bracket 6. The sleeve 16 is fitted onto the plug-in portion 14, and the sleeve 16 and the plug-in portion 14 can be corresponding polygonal structures to prevent rotation, such as triangles, rectangles, pentagons, etc. The first guide wheel 3 or the second guide wheel 4 is rotatably connected to the bracket 6 through another bearing 13.

[0037] The sleeve 16 has a second through hole 17, which is a threaded hole. A stud 15 is threaded into the threaded hole, and the end of the stud 15 can abut against the periphery of the insertion part 14. Tightening the stud 15 causes it to gradually advance within the threaded hole, and its end exerts pressure on the periphery of the insertion part 14, thereby fixing the sleeve 16 to the insertion part 14. Tightening the stud 15 in any direction releases the fixation between the sleeve 16 and the insertion part 14.

[0038] The first guide wheel 3 is disposed on the first side of the base 1, and the second guide wheel 4 is disposed on the second side of the base 1. There are two second guide wheels 4, and the angle between the moving directions of the two second guide wheels 4 is 120 degrees. The angle between the moving directions of the two second guide wheels 4 and the moving direction of the first guide wheel 3 is also 120 degrees. The drive mechanism is activated, driving the first guide wheel 3 and the second guide wheel 4 to move radially along the base 1. The first guide wheel 3 moves from the first side of the base 1 toward the irregular conductor, while the two second guide wheels 4 move simultaneously from the second side of the base 1 toward the irregular conductor at an angle of 120 degrees to each other and also at an angle of 120 degrees to the first guide wheel 3. As the guide wheels gradually approach each other, the groove on the periphery of the first guide wheel 3 contacts the corresponding part of the irregular conductor, and the two second guide wheels 4 contact the surface of the irregular conductor from different directions. Due to the angular relationship between the three guide wheels, after contacting the irregular conductor, a stable triangular constraint structure can be formed in space, applying pressure to the irregular conductor uniformly from multiple directions. It is particularly suitable for constraining sector-shaped conductors, and by changing the shape of the first guide wheel 3 and the second guide wheel 4, it can also be adapted to the shape of other irregular conductors.

[0039] A coupling and / or a reducer (not shown in the figure) is provided between the output shaft of the drive component 2 and the first gear 10. If only a coupling is provided, the power is directly transmitted to the first gear 10 through the coupling. During the power transmission process, the coupling, by virtue of its own structural characteristics, compensates for any slight displacement deviation that may exist between the output shaft of the drive component 2 and the shaft of the first gear 10, so that the first gear 10 can rotate synchronously and stably with the output shaft of the drive component 2, thereby driving the subsequent components such as the second gear 11, the nut sleeve 7, and the lead screw 8 to move, thus realizing the drive of the guide wheel. If a reducer is also provided, the power from the output shaft of the drive component 2 is first transmitted to the reducer. The transmission components inside the reducer, such as gears or worm gears, convert the high speed and low torque output of the drive component 2 into a low speed and high torque power output according to a predetermined transmission ratio. For example, a gear reducer reduces the speed and increases the torque by meshing gears with different gear ratios. The power adjusted by the reducer is then transmitted to the first gear 10 through the coupling. By adjusting the speed and torque of the reducer, and through reliable connection and displacement deviation compensation of the coupling, the power transmitted to the first gear 10 can precisely match the driving requirements of the guide wheel, achieving smooth and precise movement of the guide wheel and meeting the different working conditions of the irregular conductor fixing device for guide wheel drive. It also includes a frame 5, with the base 1 mounted on the frame 5.

[0040] This embodiment also discloses an irregular conductor processing system, including the aforementioned irregular conductor fixing device.

[0041] The irregular conductor fixing device described in this embodiment also includes a vision inspection module, which includes: a camera, using a high-resolution, high-precision industrial camera, capable of detecting the shape and size of the product to be fixed, stopping the guide rollers when they contact and adhere to the surface of the product; a light source, employing various types of light sources, such as ring light sources, backlight sources, and strip light sources, selecting the appropriate light source based on the material, shape, and inspection requirements of the irregular conductor; an image acquisition card, used to quickly and accurately transmit image data acquired by the industrial camera to a computer for processing. The image acquisition card has a high-speed data transmission interface; and an inspection system, featuring a user-friendly graphical interface for operators to easily set inspection parameters, view inspection results, and historical data. The software can establish standard inspection models for different types of irregular conductors, storing corresponding size, shape, and defect standard data. During the inspection process, the acquired image data is compared with the standard model in real time to quickly determine whether the conductor is qualified and generate a detailed inspection report, including information such as the defect type, location, and size of unqualified products.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
