Description

Technical Field

[0001] This utility model relates to the field of pressure holding equipment technology, and more specifically, to a pressure holding device for magnet bonding. Background Technology

[0002] Magnet assemblies often require bonding with other magnets or structural components using adhesives. During this process, the "pressure holding" step in the bonding and curing stage is crucial. Its purpose is to apply and maintain constant, uniform pressure to ensure consistent adhesive layer thickness, eliminate internal air bubbles, and thus achieve a high-strength bond. Currently, common pressure holding devices in the industry often employ structures where cylinders or hydraulic cylinders directly lift the pressure plate, or utilize mechanical mechanisms such as screws and cams to apply pressure. However, these existing technologies have several significant drawbacks:

[0003] 1) Insufficient control precision, easily damaging magnets: The control precision of the pressing stroke in the scheme that directly uses pneumatic or hydraulic cylinders is limited by the manufacturing precision of the equipment itself. For magnets that are inherently brittle and prone to cracking, excessive pressing force or even a small overstroke can easily cause chipping at the magnet's edge or microcracks throughout, resulting in product scrap.

[0004] 2) Difficulty in achieving high-precision micro-displacement control: To protect the magnet, the ideal pressure-holding process requires the pressure plate to achieve a small and precise final pressing displacement after contacting the magnet, in order to control the final adhesive layer thickness and pressure. Conventional power components (such as ordinary cylinders) often lack the stroke resolution to meet this precision control requirement in order to achieve sufficient idle travel speed. Using a high-precision electric servo system for this purpose would significantly increase equipment costs. Utility Model Content

[0013] Optionally, the first power component is a pneumatic cylinder or a hydraulic cylinder; the first power component is fixed on the frame.

Detailed Implementation

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] In the description of this utility model, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship when the product is in normal use.

[0029] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0030] This utility model provides a pressure-holding device for magnet bonding. Please refer to [link / reference]. Figure 1-9As shown, it includes: a base 1, with a limiting structure 101 inside the base 1; a magnet carrier 102 for holding the magnet assembly that has completed the bonding process is engaged inside the limiting structure 101, and the limiting structure 101 positions the magnet carrier 102; a pressure plate 2, fixed above the magnet carrier 102, the pressure plate 2 cooperating with the base 1 to press and hold the magnet assembly that has completed the bonding process inside the magnet carrier 102 until the magnet assembly is firmly bonded to other components, improving product quality; and a first power assembly 3, which has a... The first telescopic end 301, which reciprocates axially, includes, but is not limited to, a cylinder or a hydraulic cylinder as its first power component 3. The first power component 3 is fixed to the frame 6. A connecting bracket 302 is fixed to the first telescopic end 301. Several pairs of levers 4 are rotatably connected to a support frame 401. A rotating shaft 4011 for threading the levers 4 is provided on the support frame 401. A first roller 402 and a second roller 403 are rotatably connected to both ends of the levers 4. The first roller 402 mates with the bottom surface of the base 1, and the second roller 403 mates with the bottom surface of the connecting bracket 302. The purpose of setting up the first roller 402 and the second roller 403 is to ensure that while supporting the base 1 and the connecting bracket 302, they can also move up and down together. The distance from the rotating shaft 4011 to the first roller 402 is less than the distance from the rotating shaft 4011 to the second roller 403. With this design, when the first power component 3 drives the connecting bracket 302 downward a large distance, the base 1 drives the magnet component inside it to move upward only a small distance. A high-precision operation can be achieved with ordinary power equipment, without the need for... Using high-precision equipment saves costs; especially since pressing the magnet assembly too tightly will damage it, while pressing it too loosely will not achieve a good bonding effect; the first power component 3 is configured to drive the first telescopic end 301 to extend or retract, so that the connecting bracket 302, in conjunction with the lever 4, pushes the base 1 upward, so that the pressure plate 2 presses and holds the magnet assembly in the magnet carrier 102, or pushes the base 1 downward to release the pressure of the pressure plate 2 on the magnet assembly in the magnet carrier 102.

[0031] Regarding the limiting structure 101: including but not limited to using 4 L-shaped plates fixed at the 4 corners of the magnet carrier 102, thereby positioning the magnet carrier 102 and preventing the magnet carrier 102 from shifting in the horizontal direction.

[0032] Regarding the first roller 402 and the second roller 403: a wear-resistant layer should be provided on the surface of both rollers, and the flatness of the surfaces of the first roller 402 and the second roller 403 should be ensured so that the base 1 can be raised and lowered smoothly.

[0033] Regarding the number and settings of lever 4: (e.g.) Figure 4As shown, lever 4 is provided in two pairs and symmetrically arranged, which improves the overall support strength, extends the service life of lever 4, and ensures the stability of the base 1 and the magnetic components inside it during lifting.

[0034] In one embodiment, such as Figure 1-4 As shown, the magnet bonding and pressure-holding device also includes a second power component 5 located below the base 1. The second power component 5 includes, but is not limited to, a cylinder or a hydraulic cylinder. The second power component 5 has a second telescopic end 501 that can reciprocate axially. The second telescopic end 501 is fixedly connected to a support plate 502, and the support plate 502 is fixed to the support frame 401. The second power component 5 is configured to drive the second telescopic end 501 to extend or retract to adjust the height position of the base 1. After the magnet assembly in the magnet carrier 102 has completed the pressing and pressure holding, the second power component 5 drives the second telescopic end 501 to retract, thereby driving the base 1 to move downward quickly. At this time, there is a large operating space between the base 1 and the pressure plate 2, so that the magnet assembly after bonding, pressing and pressure holding can be removed.

[0035] In one embodiment, such as Figure 5 As shown, a plurality of first guide cylinders 503 are fixedly connected to the support plate 502; second guide cylinders 504 are slidably connected to the inner wall of the first guide cylinders 503. When the first power component 3 or the second power component 5 drives the base 1 to rise or fall, the first guide cylinders 503 and the second guide cylinders 504 cooperate to support and guide the base 1; the second guide cylinders 504 are fixedly connected to the bottom of the base 1 to guide the movement of the base 1 and provide auxiliary support for the base 1.

[0036] In one embodiment, such as Figure 8 As shown, the base 1 has several positioning holes 103 along its surface edge; the pressure plate 2 has several positioning posts 201 along its bottom edge; the positioning posts 201 cooperate with the positioning holes 103 to position the base 1 and the pressure plate 2, ensuring that the base 1 and the pressure plate 2 are positioned, which facilitates the subsequent accurate pressing of the pressure plate 2 with the magnet assembly in the magnet carrier 102.

[0037] In one embodiment, such as Figure 9 As shown, a positioning groove 202 is provided on the bottom surface of the pressure plate 2. Since the magnet assembly has a certain thickness, the positioning groove 202 is provided to facilitate the cooperation with the magnet assembly. The inner side wall of the positioning groove 202 is cooperated with the periphery of the limiting structure 101. The bottom wall of the positioning groove 202 is cooperated with the top surface of the magnet assembly in the magnet carrier 102 to continuously press the magnet assembly.

[0038] In one embodiment, such as Figure 7As shown, several extension plates 303 protrude outward from both sides of the connecting bracket 302. The greater the distance from the rotating shaft 4011 to the center of the second roller 403 than the distance from the rotating shaft 4011 to the center of the first roller 402, the smaller the distance the base 1 drives the magnet assembly inside to move upward. This allows the first power assembly 3 to control the pressing operation of the magnet assembly more accurately. The extension plates 303 can ensure a large distance between the rotating shaft 4011 and the center of the second roller 403, ensuring that the second roller 403 always supports the connecting bracket 302. The bottom surface of the extension plates 303 cooperates with the second roller 403.

[0039] In one embodiment, such as Figure 4 As shown, a reinforcing plate 304 is provided between several extension plates 303 on each side of the connecting bracket 302. The extension plates 303 need to withstand a large force, and the reinforcing plate 304 is provided to improve the strength of the extension plates 303.

[0040] In one embodiment, such as Figure 4 As shown, the connecting bracket 302 also includes a connecting part 305 that is fixedly connected to the first telescopic end 301; the connecting part 305 is located above the connecting bracket 302 to avoid interference with the pressure plate 2 when the connecting bracket 302 descends, which is equivalent to having a space to avoid the pressure plate 2; a number of connecting pieces 306 are fixed to the bottom edge of the connecting bracket 302, and the connecting pieces 306 are fixed to the connecting bracket 302.

[0041] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
