Description

Technical Field

[0001] This utility model relates to the field of packaging clamp technology, and in particular to a packaging clamp for anti-oxidation magnetic materials. Background Technology

[0002] In today's fields of electronic information technology and energy conversion and storage, magnetic materials have become core functional materials due to their importance. However, these materials are highly susceptible to oxidation and corrosion in humid or oxygen-containing environments, leading to problems such as decreased magnetic permeability and reduced coercivity, which directly affect product reliability. To overcome this problem, encapsulation technology has become one of the key processing steps after the production of magnetic materials. Traditional packaging fixtures typically use a lever-type clamping structure, where operators manually push the lever arm to clamp the opening of the packaging bag. While this design is simple, it has some inherent drawbacks.

[0003] First, lever-type clamps suffer from an imbalance in force distribution. Due to differences in the design of the lever fulcrum and force application points, the actual contact pressure on both sides of the bag opening may differ significantly during clamping. This can easily create micro-wrinkles during vacuuming, leading to localized seal failure. Second, the rigid connection of the lever structure cannot adapt to variations in bag thickness. When the bag opening thickness differs, the clamping force also varies, thus failing to guarantee the airtightness of the seal. Finally, traditional mechanical clamps lack the ability to precisely control the clamping force. Operators typically rely on experience to judge the clamping degree, which can easily lead to overpressure damaging the bag or underpressure causing secondary oxidation.

[0004] To address the aforementioned issues, some existing solutions employ pneumatic drive combined with pressure-equalizing pads to improve clamping uniformity. However, pneumatic systems suffer from response delays, and the creep characteristics of the pressure-equalizing pads cause the clamping force to decay over time. Another approach utilizes multiple independent springs to provide clamping force, but this results in pressure dispersion at each clamping point as high as ±20%, making it difficult to meet the packaging requirements of high-precision magnetic materials (such as thin magnetic cores). Therefore, there is an urgent need for a clamp that can achieve dynamic pressure equalization, possess a real-time feedback mechanism, and adapt to precision packaging requirements to solve the oxidation failure problem caused by uneven clamping force distribution in existing technologies. Utility Model Content

[0005] This invention provides an anti-oxidation magnetic material packaging clamp to solve the problem mentioned in the background art of existing packaging clamp structural design defects, which make it difficult to evenly distribute the clamping force on the edge of the packaging bag.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An anti-oxidation magnetic material packaging clamp includes a fixing frame and a clamping mechanism. The clamping mechanism includes a clamping seat, with sliding sleeves fixedly installed at both ends of the clamping seat. Sliding rods are slidably installed inside each sliding sleeve. A clamping plate is fixedly installed between the bottom ends of a pair of sliding rods. The upper sides of the fixing frame are respectively fixedly connected to the outer sides of the pair of sliding sleeves. Mounting frames are fixedly installed at both ends of the fixing frame. A first clamping block is fixedly installed at the upper end of the fixing frame, and a second clamping block is fixedly installed at the bottom end of the clamping plate. The second clamping block is aligned with the first clamping block.

[0008] Furthermore, a dual-axis motor is fixedly installed at the top of the inside of the clamping seat. The two ends of the dual-axis motor are respectively fitted with a first bidirectional screw and a second bidirectional screw, and the other ends of the first bidirectional screw and the second bidirectional screw are rotatably connected to the two ends inside the clamping seat.

[0009] Furthermore, the first bidirectional screw has a first slider threadedly connected to both ends, and the second bidirectional screw has a second slider threadedly connected to both ends.

[0010] Furthermore, a first mounting base is fixedly installed at the bottom end of both the first slider and the second slider, and a connecting rod is hinged inside the first mounting base via a pin.

[0011] Furthermore, a pair of second mounting seats are fixedly installed on both sides of the inner bottom end of the clamping plate, and the interior of the second mounting seats is hinged to the other end of the four connecting rods through a pin.

[0012] Furthermore, both the first clamping block and the second clamping block are made of silicone, and a pressure sensor is embedded in the bottom of the first clamping block.

[0013] Furthermore, a controller is fixedly mounted on the outside of the mounting bracket, and the controller is electrically connected to the pressure sensor and the dual-axis motor via wires.

[0014] Furthermore, each end of the mounting bracket has a pair of mounting holes. Furthermore, the contact surfaces of the first and second clamping blocks are provided with annular sealing strips, the cross-section of which has a semi-circular convex structure.

[0015] Furthermore, the outer surface of the slide bar is provided with laser-engraved scale marks, the minimum division value of which is 0.5mm.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This utility model, through the sliding cooperation design of the fixed frame and the sliding sleeve and sliding rod of the clamping mechanism, can realize the vertical lifting and lowering movement of the clamping plate along the sliding rod, so that the clamping force is evenly transmitted along the length direction of the packaging bag opening, avoiding the problem of local clamping failure caused by uneven force at the fulcrum of the traditional lever structure, and ensuring that the sealing of the packaging bag edge meets the standard during the vacuuming process.

[0018] 2. This utility model adopts a synchronous transmission structure of dual-axis motor driving the first bidirectional screw and the second bidirectional screw. It can achieve four-point symmetrical force application of the clamping plate through the linkage of the first slider, the second slider and the connecting rod, so that the force is balanced during the clamping process and the risk of packaging bag wrinkles and deformation is significantly reduced.

[0019] 3. This utility model, through the silicone material design of the first and second clamping blocks and the built-in pressure sensor, can adapt to the thickness fluctuation of the packaging bag during clamping, and provide real-time feedback of the clamping pressure to the controller to form a closed-loop control, preventing bag damage due to overpressure or poor sealing due to underpressure.

[0020] 4. This utility model, through the standardized design of the mounting holes of the mounting bracket, can be adapted to the mounting interfaces of different models of packaging equipment. With the scale markings on the outer surface of the slide bar, the clamping stroke can be quantitatively adjusted, improving the versatility and repeatability of the clamp, and is suitable for the packaging needs of irregularly shaped magnetic materials such as sheet and block.

[0030] Example

[0031] Please see Figure 1-5This utility model provides a packaging clamp for anti-oxidation magnetic materials, including a fixing frame 1 and a clamping mechanism 2. The clamping mechanism 2 includes a clamping seat 6, with sliding sleeves 8 fixedly installed at both ends of the clamping seat 6. Sliding rods 9 are slidably installed inside each sliding sleeve 8. A clamping plate 7 is fixedly installed between the bottom ends of a pair of sliding rods 9. The upper sides of the fixing frame 1 are fixedly connected to the outer sides of a pair of sliding sleeves 8 respectively. Mounting frames 4 are fixedly installed at both ends of the fixing frame 1. A first clamping block 3 is fixedly installed at the upper end of the fixing frame 1, and a second clamping block 10 is fixedly installed at the bottom end of the clamping plate 7. The second clamping block 10 is aligned with the first clamping block 3. The fixing frame 1 provides a stable mounting base for the entire clamp. The sliding sleeve 8 and sliding rod 9 of structure 2 slide together, allowing the clamping plate 7 to move up and down along the sliding rod 9. This facilitates adjustment of the distance between the clamping plate 7 and the first clamping block 3, and makes it easier to clamp and fix the port of the magnetic material packaging bag. Because the clamping plate 7 is slidably connected to the clamping seat 6, the force applied by the power source is evenly transmitted along the sliding direction of the clamping plate 7, making the force on each part of the clamping plate 7 more uniform when in contact with the object being clamped. The first clamping block 3 and the second clamping block 10 are aligned to stably clamp the port of the magnetic material packaging bag, preventing air from entering the packaging bag due to uneven clamping force during the vacuum packaging process of the magnetic material. The outer surface of the sliding rod 9 is laser-engraved with scale markings. These scale markings extend downwards from the upper end face of the sliding sleeve 8 as the reference zero point, marking a range of 0-50mm, with the smallest division accurate to 0.5mm. Operators can monitor the lifting and lowering stroke of the clamping plate 7 in real time by observing the corresponding positions of the edge of the sliding sleeve 8 and the scale marks. Combined with the pressure feedback data from the controller 19, precise and visual control of the clamping process can be achieved. Practical application verification has shown that this design can achieve a clamping position repeatability accuracy of ±0.2mm.

[0032] A dual-axis motor 11 is fixedly installed at the top of the inside of the clamping base 6. The two ends of the dual-axis motor 11 are respectively fitted with a first bidirectional screw 12 and a second bidirectional screw 13. The other ends of the first bidirectional screw 12 and the second bidirectional screw 13 are rotatably connected to the two ends inside the clamping base 6. The dual-axis motor 11 inside the clamping base 6 simultaneously drives the first bidirectional screw 12 and the second bidirectional screw 13 to rotate, providing a power source for the lifting and lowering of the clamping plate 7. The dual-axis drive realizes the centralized transmission and efficient utilization of power, ensuring the stability and synchronization of the lifting and lowering process of the clamping plate 7.

[0033] The first bidirectional screw 12 is threaded to both ends with a first slider 14, and the second bidirectional screw 13 is threaded to both ends with a second slider 15. The first bidirectional screw 12 and the second bidirectional screw 13 are threaded to the first slider 14 and the second slider 15, respectively, so that the rotation of the screw is converted into the linear motion of the slider. The movement distance of the first slider 14 and the second slider 15 can be accurately controlled by the threaded transmission, thereby adjusting the lifting height of the clamp 7.

[0034] The bottom ends of the first slider 14 and the second slider 15 are both fixedly mounted with a first mounting base 16. The inside of the first mounting base 16 is hinged with a connecting rod 18 through a pin. The first mounting base 16 at the bottom ends of the first slider 14 and the second slider 15 and the hinged connecting rod 18 constitute a linkage transmission structure. When the first slider 14 and the second slider 15 move, the force is transmitted to the clamping plate 7 through the connecting rod 18, which drives the clamping plate 7 to rise and fall smoothly. At the same time, the linkage structure can enhance the stability of the transmission and prevent the clamping plate 7 from shaking during the rising and falling process.

[0035] A pair of second mounting seats 17 are fixedly installed on both sides of the bottom of the inner side of the clamping plate 7. The interior of the second mounting seats 17 is hinged to the other end of the four connecting rods 18 through a pin. The second mounting seats 17 inside the clamping plate 7 are hinged to the connecting rods 18, so that the clamping plate 7 can achieve a smooth and reliable lifting movement under the coordinated action of multiple connecting rods 18. This makes the power source applied to the clamping plate 7 more evenly distributed, ensuring the firmness of the clamping plate 7 when it is used with the fixing frame 1 to clamp the port of the magnetic material packaging bag.

[0036] Both the first clamping block 3 and the second clamping block 10 are made of silicone. A pressure sensor is embedded in the bottom of the first clamping block 3. The silicone material provides good flexibility and anti-slip properties, preventing damage to the surface of magnetic materials and enhancing clamping stability. The pressure sensor inside the first clamping block 3 monitors the clamping force in real time, preventing excessive force from affecting the vacuum tube inserted into the packaging bag or insufficient force from causing the packaging bag to loosen. An annular sealing strip is integrally formed on the contact surface edge of the first clamping block 3 and the second clamping block 10. This annular sealing strip is injection molded from silicone and has a semi-circular protrusion with a radius of 1.2mm. When the second clamping block 10 closes with the first clamping block 3, the annular sealing strip undergoes an elastic deformation of 0.8-1.2mm, forming a double-sealed interface. This effectively blocks external air from penetrating along the clamping edge, reducing the leakage rate of the packaging bag clamping area by 37% according to tests.

[0037] A controller 19 is fixedly installed on the outside of the mounting frame 4. The controller 19 is electrically connected to the pressure sensor and the dual-axis motor 11 via wires. The controller 19 on the outside of the mounting frame 4 is electrically connected to the pressure sensor and the dual-axis motor 11. It can receive the clamping force data fed back by the pressure sensor and control the operation of the dual-axis motor 11 to realize automatic adjustment of the clamping force, ensuring that the clamping of the magnetic material packaging bag is stable and does not cause damage, thereby improving the reliability of the packaging fixture.

[0038] One end of each mounting frame 4 is provided with a pair of mounting holes 5. The mounting holes 5 on the mounting frame 4 facilitate the installation and fixation of the entire vacuum packaging fixture on the vacuum packaging equipment. The fixture is fixed by bolts or other connecting parts passing through the mounting holes 5. The installation and disassembly are convenient, which enhances the versatility and applicability of the fixture. It can be flexibly installed on different equipment according to different packaging needs.

[0039] Specifically, the working principle of this anti-oxidation magnetic material packaging clamp is as follows: In use, the clamp is first fixed to the vacuum packaging equipment through the mounting holes 5 on the mounting frame 4. The packaging bag containing magnetic material is placed between the first clamping block 3 and the second clamping block 10. The dual-axis motor 11 in the clamping seat 6 is started. The dual-axis motor 11 drives the first bidirectional screw 12 and the second bidirectional screw 13 to rotate, so that the first slider 14 and the second slider 15, which are threadedly connected to the screw, move along the screw direction. When the first slider 14 and the second slider 15 move, the force is transmitted to the second mounting seat 17 on the clamping plate 7 through the connecting rod 18 hinged to the first mounting seat 16 at the bottom, which drives the clamping plate 7 to rise and fall smoothly along the slide rod 9 until the second clamping block 10 clamps the port of the packaging bag with the first clamping block 3. During this process, the pressure sensor inside the first clamping block 3 monitors the clamping force in real time and feeds the data back to the controller 19 on the outside of the mounting frame 4. If the controller 19 finds that the clamping force is too large or too small, it controls the dual-axis motor 11 to adjust its operation in time, thereby adjusting the lifting degree of the clamping plate 7 and realizing automatic adjustment of the clamping force. Since the clamping plate 7 and the clamping seat 6 are slidably connected through the sliding sleeve 8 and the sliding rod 9, and adopt the linkage transmission structure, the clamping plate 7 is subjected to uniform force, ensuring that the port of the packaging bag is firmly and stably clamped, preventing air from entering the interior of the packaging bag, and ensuring that the magnetic material is not oxidized during the vacuum packaging process.

[0040] It should be noted that all standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Furthermore, since this application is mainly used to protect mechanical devices, this application will not explain the control method and circuit connection in detail.

[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
