Description

Technical Field

[0001] This disclosure relates to the field of electronic equipment technology, and more particularly to a clamp and pressing device. Background Technology

[0002] In modern precision industrial manufacturing systems, the pressing and fixing processes between components serve as the core guarantee for product quality and performance, and their technical level directly determines the final quality of the product. Taking the pressing operation of component A and the hinge as an example, the traditional process usually involves the following steps: First, component A is precisely positioned onto the molding fixture. Then, adhesive is applied to the preset area and the hinge is assembled. Next, the matching molding pressure block is covered, and a vertical downward thrust is applied using a pneumatic cylinder. Finally, the molding fixture, along with component A and the pressure block, is moved to the curing station and left to stand for 20 minutes to allow the adhesive to cure.

[0003] However, in this traditional process, the molding block is mostly made of lightweight aluminum. Even with the assistance of a pneumatic cylinder, it cannot provide continuous and sufficient contact pressure, which makes it impossible for the hinge to fully fit the surface of part A. Summary of the Invention

[0004] This disclosure provides a solution to at least address the aforementioned technical problems existing in the prior art.

[0005] The first aspect of this disclosure provides a clamp, comprising: First magnetic chuck; The pressure block is provided with a second magnetic attraction element; A driving mechanism, connected to the second magnetic attractor, is used to drive the second magnetic attractor to move so that there is an attractive magnetic force between the first magnetic attractor and the second magnetic attractor.

[0006] Furthermore, the pressure block is provided with a mounting hole, the second magnetic member is disposed in the mounting hole, and the second magnetic member can rotate within the mounting hole along its own axis; The driving mechanism is used to drive the second magnetic chuck to rotate so that there is an attractive magnetic force between the first magnetic chuck and the second magnetic chuck. Furthermore, the driving mechanism includes a guide rail, a slider, and a connecting rod; The pressure block is provided with a first connecting shaft, the axis of the second magnetic suction member is provided with a second connecting shaft, the guide rail is connected to the first connecting shaft and the second connecting shaft respectively, the guide rail extends radially along the mounting hole, and the slider is movably disposed on the guide rail; The slider is provided with a first rotating shaft, the second magnetic suction member is provided with a second rotating shaft, and the two ends of the connecting rod are respectively rotatably connected to the first rotating shaft and the second rotating shaft; The connecting rod is used to drive the second magnetic element to rotate as the slider moves along the extension direction of the guide rail.

[0007] Furthermore, it also includes an elastic element, the two ends of which are respectively connected to the first rotating shaft and the first connecting shaft.

[0008] Furthermore, the guide rail is provided with a guide groove that extends radially along the mounting hole, and the slider slides in cooperation with the guide groove.

[0009] Furthermore, the driving mechanism includes a driving member that cooperates with the slider to drive the slider to move along the extension direction of the guide rail.

[0010] Furthermore, the driving component is a cylinder, and the telescopic end of the cylinder is connected to the slider.

[0011] Furthermore, the first magnetic attractor is a magnetic conductor, and the pressure block includes a non-magnetic conductor extending in the vertical direction of the first magnetic attractor.

[0012] Furthermore, the first magnetic element is an iron sheet, and the second magnetic element is a magnet.

[0013] A second aspect of this disclosure provides a pressing device, including the clamp described in the first aspect.

[0014] The technical solution provided in this disclosure has the following advantages compared with the prior art: The clamp provided in this embodiment includes a first magnetic attractor, a pressure block, and a driving mechanism. The pressure block is equipped with a second magnetic attractor. The driving mechanism is connected to the second magnetic attractor and is used to drive the second magnetic attractor to move, so that the first magnetic attractor and the second magnetic attractor have an attractive magnetic force. Taking the pressing of part A and the hinge as an example, in use, the first magnetic attractor is first placed on one side of part A, and the pressure block is placed on one side of the hinge. The driving mechanism can flexibly control the magnetic force between the first magnetic attractor and the second magnetic attractor. When it is necessary to apply greater pressure to make the hinge and part A fit completely, by making the first magnetic attractor and the second magnetic attractor have an attractive force, the pressure block can generate a continuous and stable downward pressure, making up for the deficiency of insufficient gravity of traditional aluminum pressure blocks.

[0019] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0020] Combination Figure 1 , Figure 2 and Figure 3 As shown, the clamp provided in this embodiment includes a first magnetic suction member 1, a pressure block 2, and a driving mechanism; the pressure block 2 is provided with a second magnetic suction member 3; the driving mechanism is connected to the second magnetic suction member 3 and is used to drive the second magnetic suction member 3 to move so that there is a magnetic force attracting each other between the first magnetic suction member 1 and the second magnetic suction member 3.

[0021] Taking the pressing of part A8 and hinge 9 as an example, in use, the first magnetic suction element 1 is first placed on one side of part A8, and the pressure block 2 is placed on one side of hinge 9. The drive mechanism can flexibly control the magnetic force between the first magnetic suction element 1 and the second magnetic suction element 3. When greater pressure is required to make hinge 9 and part A8 fit completely, by making the first magnetic suction element 1 and the second magnetic suction element 3 have an attractive force, the pressure block 2 can generate a continuous and stable downward pressure, making up for the deficiency of insufficient gravity of traditional aluminum pressure block 2; when it is necessary to disassemble or adjust the parts, by weakening the magnetic force or making the first magnetic suction element 1 and the second magnetic suction element 3 repel each other (or have no attraction), the clamping parts can be separated conveniently and quickly, improving operating efficiency.

[0022] Stable and sufficient pressure ensures that the adhesive forms a uniform and high-strength bonding interface after curing, effectively avoiding stress concentration and weak bonding areas, significantly reducing the probability of failures such as component loosening and detachment, extending product lifespan, and reducing later maintenance costs and quality control pressure.

[0023] Optionally, the first magnetic suction element 1 is disposed on the first clamping element and the pressure block 2 is disposed on the second clamping element. In this embodiment, by replacing the first clamping element, the second clamping element and the pressure block 2 of different specifications, it can adapt to the pressing operation requirements of various parts A 8 and hinges 9, improve the versatility and production applicability of the fixture, and provide a reliable guarantee for high-precision and high-quality assembly in industrial manufacturing.

[0024] In some specific embodiments, the pressure block 2 has a mounting hole, and the second magnetic attractor 3 is disposed in the mounting hole, and the second magnetic attractor 3 can rotate within the mounting hole along its own axis; a driving mechanism is used to drive the second magnetic attractor 3 to rotate, so that there is an attractive magnetic force between the first magnetic attractor 1 and the second magnetic attractor 3. Integrating the second magnetic attractor 3 into the mounting hole of the pressure block 2, making the second magnetic attractor 3 and the pressure block 2 an integrated design, can reduce external connecting parts and complex transmission structures, effectively reducing the overall size and weight of the fixture. The rotary second magnetic attractor 3 can achieve faster and more stable magnetic force switching, avoiding magnetic force fluctuations caused by distance changes.

[0025] In some specific embodiments, the driving mechanism includes a guide rail 4, a slider 5, and a connecting rod 6. The pressure block 2 is provided with a first connecting shaft 21, and the axis of the second magnetic suction member 3 is provided with a second connecting shaft 31. The guide rail 4 is connected to the first connecting shaft 21 and the second connecting shaft 31 respectively. The guide rail 4 extends radially along the mounting hole, and the slider 5 is movably mounted on the guide rail 4. The design of the guide rail 4 extending radially along the mounting hole cleverly utilizes the internal space of the pressure block 2, making the driving mechanism highly integrated with the structure of the pressure block 2, and significantly reducing the overall volume of the fixture. The slider 5 is provided with a first rotating shaft 51, and the second magnetic suction member 3 is provided with a second rotating shaft 32. The two ends of the connecting rod 6 are rotatably connected to the first rotating shaft 51 and the second rotating shaft 32 respectively. The connecting rod 6 is used to drive the second magnetic suction member 3 to rotate as the slider 5 moves along the extension direction of the guide rail 4. The guide rail 4 provides precise guidance for the linear motion of the slider 5, and the connecting rod 6 mechanism accurately converts this linear displacement into a rotation angle, realizing precise control of the rotation angle of the second magnetic suction member 3. By calculating the correspondence between the displacement and rotation angle of slider 5, angle control precision can be achieved, ensuring accurate adjustment of the magnitude and direction of the magnetic force between the first magnetic chuck 1 and the second magnetic chuck 3, thus meeting the requirements of high-precision assembly processes. In this embodiment, the linear motion of guide rail 4 and slider 5 is efficiently converted into the rotational motion of the second magnetic chuck 3 through the linkage 6 mechanism. Compared with the traditional method of directly driving rotation with a motor, this reduces transmission links and lowers energy loss.

[0026] In some specific embodiments, an elastic element 7 is also included, with its two ends connected to the first rotating shaft 51 and the first connecting shaft 21, respectively. The elastic deformation characteristics of the elastic element 7 cause the second magnetic chuck 3 to generate an adaptive restoring force during rotation. When no magnetic force is needed between the first magnetic chuck 1 and the second magnetic chuck 3, the elastic element 7 can, under the action of its own elastic restoring force, cause the second magnetic chuck 3 to rotate back to its initial position in the opposite direction. Optionally, the elastic element 7 can be a spring or other elastic device.

[0027] In some specific embodiments, the guide rail 4 is provided with a guide groove 41, which extends radially along the mounting hole. The slider 5 slides in cooperation with the guide groove 41, making the rotation drive of the second magnetic suction member 3 more precise.

[0028] In some specific embodiments, the driving mechanism includes a driving member 10, which cooperates with the slider 5 to drive the slider 5 to move along the extension direction of the guide rail 4. The driving member 10 can achieve precise control over the moving distance and speed of the slider 5, thereby accurately adjusting the rotation angle and speed of the second magnetic suction member 3.

[0029] In some specific implementations, the usage process is as follows: Place part A8 precisely on the molding fixture. After applying glue, place hinge 9 according to the process requirements to prepare for subsequent pressing. The cylinder moves downward, applying a thrust to the slider 5. With the help of the stable linear driving force of the pneumatic cylinder, the transmission process is started. The slider 5 moves downward under the push force, and through the linkage of the connecting rod 6, it drives the second magnetic suction component 3 to rotate, changing its magnetic direction, in preparation for magnetic attraction and pressure cooperation. The cylinder continues to act, applying pressure to the pressure block 2. At the same time, the slider 5 and the connecting rod 6 cooperate to rotate the second magnetic attractor 3 to an orientation state of "left N pole, right S pole" or "left S pole, right N pole", thus constructing a specific magnetic circuit.

[0030] The bottom iron plate of the molding fixture (first magnetic component 1) generates an attractive force due to the orientation of its magnetic poles. This force is precisely applied to the hinge 9, achieving stable pressing. At this point, the fixture can be moved and left to stand for 20 minutes to allow the adhesive to cure. This solution uses only one set of pneumatic cylinders to support continuous mass production, achieving high-efficiency production with low-cost equipment. Moreover, the pressing state remains stable when the fixture is moved, eliminating concerns about poor hinge 9 fit or adhesion failure caused by tilting of the pressure block 2 or insufficient pressure.

[0031] After the glue has fully cured, push the slide rail upwards. The elastic element 7 will drive the slide rail to reset and lock in its initial position. The magnetic circuit will disconnect as the mechanism resets, the magnetic force will disappear, and the pressure block 2 can be removed smoothly, and part A 8 can be taken away.

[0032] In some specific embodiments, the driving component 10 is a cylinder, and the telescopic end of the cylinder is connected to the slider 5. The cylinder uses compressed air as a power source, providing stable and relatively large thrust. Compared to traditional electric drive methods, it can effectively overcome greater load resistance when pushing the slider 5 to rotate the second magnetic component 3. The cylinder has a simple structure and fewer internal moving parts, offering higher reliability and anti-interference capabilities compared to the complex mechanical structures and electronic components of electric drives.

[0033] In some specific embodiments, the first magnetic attractor 1 is a magnetic conductor 23, the pressing block 2 includes a non-magnetic conductor 22 extending perpendicularly to the first magnetic attractor 1, and the other areas of the pressing block 2 are magnetic conductors 23. (Combined with...) Figure 4 and Figure 5 As shown, the first magnetic attractor 1 acts as a magnetic conductor 23, working in conjunction with the vertically extending non-magnetic conductor 22 in the pressure block 2 to achieve precise switching of the magnetic circuit between "on" and "off". For example, in the "OFF" position, the non-magnetic conductor 22 blocks the outward extension of the magnetic lines of force of the second magnetic attractor 3, and the magnetic circuit is enclosed internally, with no external attraction force. In the "ON" position, the second magnetic attractor 3 shifts, and the magnetic conductor 23 guides the magnetic lines of force of the second magnetic attractor 3 to extend outward to the workpiece (or corresponding component), forming an attraction magnetic circuit. By changing the mechanical structure (the driving component 10 drives the second magnetic attractor 3 to rotate), the magnetic attraction "on-off" function is easily achieved.

[0034] In some specific embodiments, the first magnetic attractor 1 is an iron sheet, and the second magnetic attractor 3 is a magnet. The iron sheet, acting as a magnetic conductor 23, can significantly enhance the magnetic field strength and magnetic field concentration generated by the magnet. The magnet's magnetism can be used to drive the second magnetic attractor 3 to rotate or shift via a cylinder, quickly achieving magnetic connection or disconnection with the iron sheet.
