Description

Technical Field

[0001] This utility model relates to the technical field of demagnetizing coil production equipment, specifically a demagnetizing coil packaging auxiliary fixture. Background Technology

[0002] Encapsulation of demagnetizing coils is a key process for ensuring stable coil performance and lifespan. The core involves insulating and protecting the demagnetizing coil, making it suitable for electronic devices, industrial instruments, medical equipment, and other applications. Encapsulation materials often include high-temperature resistant epoxy resin and silicone, formed through molding and potting processes. These materials provide insulation, moisture resistance, and impact resistance. The encapsulation process requires precise control of temperature and curing time to ensure a tight fit between the coil and the encapsulation body, preventing internal air bubbles from affecting magnetic field conduction. This process isolates the coil from external humidity, dust, and mechanical damage, while simultaneously fixing the coil structure and reducing electromagnetic leakage, ensuring the demagnetizing accuracy and stability of the demagnetizing coil under complex operating conditions. It is a core supporting process for the mass production of demagnetizing equipment. However, existing demagnetizing coil encapsulation methods still have certain problems: For example, the technical solution of a demagnetizing coil packaging fixture with application number 201220256728.7 is as follows: it includes a demagnetizing coil, and clamps are provided around the demagnetizing coil. The clamps are connected and fixed by screws. The gap between the demagnetizing coil and the clamps is sealed with glue on the surface of the flat coil. The packaging of the demagnetizing coil is a key process of bonding and fixing the coil body with the insulating shell, potting glue and other packaging materials. It has extremely high requirements for the positioning accuracy and clamping stability of the fixture. Existing auxiliary fixtures have obvious defects: the positioning structure is simple and cannot be adapted to coils of different specifications. Moreover, the fixture is cumbersome to disassemble and assemble, and it is difficult to remove the coil after packaging, which affects the production efficiency. Therefore, there is an urgent need for a demagnetizing coil packaging auxiliary fixture with strong versatility, accurate positioning and convenient operation.

[0003] In view of this, in-depth research was conducted on the above issues, which led to the creation of this case.

[0004] To address the aforementioned issues, an innovative design was implemented based on the existing packaging fixture for demagnetizing coils. Utility Model Content

[0005] The purpose of this invention is to provide an auxiliary fixture for packaging demagnetizing coils, so as to solve the problems mentioned in the background art, such as the inability to adapt to coils of different specifications and poor versatility.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A demagnetizing coil packaging auxiliary fixture includes a base, which is square in shape and has four anti-slip pads on the bottom. The base has an internal cavity, and baffles are provided on the outer sides of the four sides. The upper surface of the base has guide grooves on the left and right sides. The upper surface of the base has three sliding grooves, and sliding columns are slidably connected inside the sliding grooves. A fixture body is fixedly installed on the top of each sliding column. There are three fixture bodies, and each fixture body extends outward to form a fixing structure for the inner circle of the demagnetizing coil package.

[0007] Preferably, the guide channels are all formed on the upper surface and side of the base, and the inside of each guide channel is provided with an inclined flow-guiding surface.

[0008] By adopting the above technical solution, the guide channel and the inclined flow surface that connect the upper surface and the side of the base improve the efficiency of adhesive discharge, prevent adhesive from accumulating at the edge of the base, reduce the amount of subsequent cleaning work, and improve maintenance efficiency.

[0009] Preferably, the base has a mounting groove in the middle of its bottom, and a servo motor is fixedly installed inside the mounting groove.

[0010] The above technical solution uses a servo motor installed in the mounting slot at the bottom of the base. Compared with an external motor design, this reduces the overall height of the equipment, decreases the space occupied, enhances the motor's internal protection, prevents potting compound from dripping and damaging the motor, and extends its service life.

[0011] Preferably, a turntable is connected and installed at the output end above the servo motor, and the surface of the turntable is provided with three positioning slots, and the angle between two adjacent positioning slots and the center of the turntable is 120°.

[0012] Using the above technical solution, the servo motor-driven turntable and the positioning slots distributed at 120° angles improve the synchronous expansion accuracy of the three clamp bodies compared to manual adjustment. The uniform angle design ensures that the coil package is subjected to balanced force, avoids deformation of the package, and ensures stable performance of the demagnetizing coil.

[0013] Preferably, each of the positioning grooves is slidably connected to a sliding column, and the bottom of the sliding column is slidably connected to a slide rail, and the slide rail is fixedly installed on the bottom surface of the inner cavity of the base.

[0014] Using the above technical solution, the sliding column in the positioning groove slides in conjunction with the slide rail on the bottom surface of the base cavity, reducing the resistance to the movement of the sliding column. The dual guidance reduces the swaying amplitude when the fixture body expands, further improving the positioning accuracy and adapting to high-precision packaging requirements.

[0015] Preferably, the clamp body is an arc-shaped elastic block structure.

[0016] Using the above technical solution, the clamp body with the arc-shaped elastic block structure has a higher fit with the inner circle of the coil package than a rigid clamp. The elasticity can buffer the clamping force and avoid damage to the surface of the package, while also being suitable for packages with slight dimensional deviations.

[0017] Preferably, the clamp body is a fractal vise structure, and an elastic layer is provided on the side of the clamp body near the demagnetizing coil package.

[0018] Using the above technical solution, the clamp body of the fractal vise structure is combined with an elastic layer. Compared with ordinary arc clamps, the clamping force adjustment range is widened, which can be adapted to packaging materials with different hardness. The elastic layer is made of rubber to avoid direct contact between the clamp and the package, reduce the surface indentation rate, and enhance the anti-slip performance, ensuring the stability of the packaging process.

[0019] Compared with the prior art, the beneficial effects of this utility model are: this demagnetizing coil packaging auxiliary fixture, 1. The combination of baffles and flow channels solves the problems of potting compound waste and cleaning. The baffles on the four sides of the base can effectively prevent potting compound from overflowing and avoid contaminating the surrounding environment of the equipment. The flow channels on the base, together with the inclined flow surface, quickly discharge excess glue. Compared with the traditional non-flow structure, the potting compound waste rate is reduced, the subsequent cleaning workload is reduced, and the economy and convenience of the encapsulation process are significantly improved. 2. Expandable clamps with multiple types of clamp bodies break through the bottleneck of versatility and adaptability: The servo motor driven expandable clamps can be adapted to demagnetizing coil packages with different inner diameters through synchronous expansion, which improves the versatility compared to fixed clamps. The two types of clamp bodies, arc-shaped elastic blocks and fractal vises, are adapted to package materials with conventional sizes and special hardness respectively, improving the fit and widening the clamping force adjustment range. This can not only ensure the stable clamping of coils of different specifications, but also avoid damage to the package, adapting to the production needs of multiple scenarios.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1 Please see Figure 1-5 This utility model provides a technical solution: A demagnetizing coil packaging auxiliary fixture includes a base 1, which has a square structure and four anti-slip pads on the bottom. The base 1 also has an internal cavity, and baffle plates 2 are provided on the four outer sides of the base 1. The upper surface of the base 1 has guide grooves 3 on both the left and right sides. The upper surface of the base 1 has three sliding grooves, and sliding posts 8 are slidably connected inside the sliding grooves. The top of each sliding post 8 is fixedly mounted with a fixture body 10. There are three fixture bodies 10, and each fixture body 10 extends outward to form a fixing structure for the inner circle of the demagnetizing coil packaging.

[0024] The flow channels 3 are all opened on the upper surface and side of the base 1, and the flow channels 3 are all provided with inclined flow guiding surfaces. The flow channels 3 and inclined flow guiding surfaces that connect the upper surface and side of the base 1 improve the efficiency of adhesive discharge, prevent adhesive from accumulating at the edge of the base 1, reduce the amount of subsequent cleaning work, and improve maintenance efficiency.

[0025] The base 1 has a mounting groove 4 in the center of its bottom, and a servo motor 5 is fixedly installed inside the mounting groove 4. A turntable 6 is connected and installed above the output end of the servo motor 5. Each turntable 6 has three positioning grooves 7 on its surface, and the angle between any two adjacent positioning grooves 7 and the center of the turntable 6 is 120°. Each positioning groove 7 has a sliding column 8 slidably connected inside it, and the bottom of the sliding column 8 is slidably connected to a slide rail 9. The slide rail 9 is fixedly installed on the bottom surface of the internal cavity of the base 1. The clamp body 10 has an arc-shaped elastic block structure. Compared with an external motor design, the servo motor 5 installed in the mounting groove 4 at the bottom of the base 1 has a lower overall height and less space occupation. The motor's internal protection is enhanced, preventing potting compound from dripping and damaging the motor, and extending its service life. The turntable 6 driven by the servo motor 5 and the positioning grooves 7 distributed at a 120° angle improve the accuracy of synchronous expansion of the three clamp bodies 10 compared to manual adjustment. The uniform angle design ensures balanced force on the coil package, avoids deformation of the package, and ensures stable performance of the demagnetizing coil. The sliding column 8 in the positioning groove 7 slides in cooperation with the slide rail 9 on the bottom surface of the base 1 cavity. The sliding resistance of the sliding column 8 is reduced. The dual guidance reduces the shaking amplitude when the clamp body 10 expands, further improving the positioning accuracy and adapting to high-precision packaging requirements. The clamp body 10 with an arc-shaped elastic block structure has a better fit with the inner circle of the coil package than a rigid clamp. The elasticity can buffer the clamping force and avoid damage to the surface of the package. It is also suitable for packages with slight dimensional deviations.

[0026] Example 2 Please see Figure 6 This utility model provides a technical solution: The clamp body 10 is a fractal vise structure, and an elastic layer is provided on the side of the clamp body 10 near the demagnetizing coil package. The clamp body 10 with the fractal vise structure and the elastic layer have a wider range of clamping force adjustment compared with ordinary arc clamps, and can adapt to packaging materials with different hardness. The elastic layer is made of rubber to avoid direct contact between the clamp and the package, reduce the surface indentation rate, and enhance the anti-slip performance, ensuring the stability of the packaging process.

[0027] Working principle: When using this utility model, Equipment preparation stage: Place the demagnetizing coil package in the center of the base 1, set the speed and direction of the servo motor 5 through the control module, ensure that the guide groove 3 is not blocked, and apply grease to the surface of the slide rail 9 to reduce friction; Fixture adjustment stage: Start the servo motor 5, its output end drives the turntable 6 to rotate, the positioning groove 7 on the turntable 6 drives the slide column 8 to slide outward along the slide rail 9, and the fixture body 10 at the top of the slide column 8 expands synchronously along the slide groove of the base 1 until it is tightly fitted with the inner circle of the coil package. The servo motor 5 stops running, and the clamping and positioning are completed. Encapsulation and flow guiding stage: potting adhesive is poured, the baffle plate 2 prevents the adhesive from splashing outward, and the excess adhesive is discharged from the base 1 along the inclined flow guiding surface of the flow guiding groove 3. After the encapsulation and curing are completed, the servo motor 5 is started in reverse, and the turntable 6 drives the sliding column 8 and the clamp body 10 to retract and reset, so that the encapsulated coil can be easily taken out.
