Description

Technical Field

[0001] This utility model relates to a magnetic attraction module, specifically a magnetic attraction module and its device. Background Technology

[0002] Existing magnetic modules require continuous power to maintain their magnetic force. This leads to significant energy consumption, especially in applications where workpieces need to be held for extended periods. More importantly, in the event of a power outage or failure, the magnetic module immediately loses its magnetism, causing the workpiece to fall and posing a serious safety hazard. Utility Model Content

[0003] Existing magnetic modules require continuous power to maintain attraction, which not only wastes energy but also causes the magnetic force to be lost immediately when the power is cut off, resulting in the workpiece falling off and posing a serious safety risk.

[0004] This invention provides a magnetic attraction module, the core of which combines a permanent magnet and a controllable electromagnetic coil. The permanent magnet has two opposing ends, each containing a magnetic attraction direction and a magnetic attraction force, respectively outputting and receiving magnetic lines of force to generate a magnetic attraction force in the magnetic attraction direction, providing a stable attraction force without power supply; while the coil is located at the same end around the permanent magnet and can be energized to generate a reverse magnetic attraction force in the opposite magnetic attraction direction; wherein, the reverse magnetic attraction direction is opposite to the magnetic attraction direction, and the reverse magnetic attraction force is at least 80% greater than the magnetic attraction force, thereby canceling or weakening the magnetic force and realizing the release of the workpiece.

[0005] This design enables an "electrical adsorption, electrical release" operation mode. This solves two major problems of traditional magnetic handling devices: high energy consumption and safety concerns during power outages. Even in the power-off state, the permanent magnet can still firmly adsorb the workpiece, ensuring operational safety while significantly reducing energy consumption. It is particularly suitable for applications requiring frequent or large-scale workpiece adsorption. Attached Figure Description

[0007] Symbol explanation: 10 magnetic modules 11 permanent magnets 12 coils 13 casing 20 bases 30 power supply 40 devices Detailed Implementation

[0008] Please refer to Figure 1 The magnetic module 10 disclosed in this embodiment is a columnar structure, mainly comprising a permanent magnet 11 and a coil 12.

[0009] The permanent magnet 11 is made of a strong magnetic material, such as neodymium iron boron or other similar strong magnetic materials, and generates a strong magnetic field under suitable conditions. In this embodiment, the permanent magnet 11 can be cylindrical in shape, with two opposing ends, which are the two magnetic poles of the permanent magnet 11. Therefore, the permanent magnet 11 defines a magnetic attraction direction and a magnetic attraction force along an axis at both ends. The two ends respectively output and receive magnetic field lines in the magnetic attraction direction to generate the magnetic attraction force, which provides the magnetic force to attract a workpiece.

[0010] The coil 12 is positioned near one end of the permanent magnet 11, generating the magnetic attraction force. The coil 12 can be energized to generate a reverse magnetic attraction force in a reverse magnetic direction. Preferably, the reverse magnetic attraction direction is completely opposite to the magnetic attraction direction, or the angle between them is less than 10%. Preferably, the reverse magnetic attraction force is greater than 80% of the magnetic attraction force, so that the reverse magnetic attraction force and the magnetic attraction force cancel each other out. By controlling the energization state of the coil 12, the magnetic force of the permanent magnet 11 can be weakened, achieving a demagnetization or demagnetization effect when releasing the workpiece.

[0011] Preferably, the difference between the anti-magnetic attraction force and the magnetic attraction force is less than 10%, or the anti-magnetic attraction force can gradually release the workpiece by detecting the weight of the workpiece and progressively changing the power of the coil 12, thereby reducing the danger of sudden release of the workpiece.

[0012] In this embodiment, the permanent magnet 11 is a rectangular prism, and the coil 12 is wound around an outer ring surface of the permanent magnet 11. Alternatively, multiple coils 12 can be arranged in a ring on the outer ring surface of the permanent magnet 11, with the direction of the anti-magnetic attraction force of each coil 12 being opposite to the direction of the magnetic attraction force. In this way, different attraction force control effects can be achieved by adjusting the start-up time of each coil 12.

[0013] Preferably, the magnetic module 10 includes a housing 13, which may be metal, that covers and secures the permanent magnet 11 and the coil 12. This allows the magnetic module 10 to have a modular function, making it easy to install and apply in related equipment, such as processing tools, robotic arms, etc.

[0014] In summary, the magnetic attraction module 10 combines the permanent magnet 11 and the coil 12 in its structural design. The permanent magnet 11 generates the magnetic attraction force, while the coil 12 generates a counter-magnetic attraction force when energized. The direction of this counter-magnetic attraction force is opposite to that of the magnetic attraction force, achieving the effect of adsorption without electricity and release upon energization. Besides its energy-saving advantages, it also improves safety during power outages. For example, when positioning a workpiece at a specific location on the magnetic attraction module 10, the input power to the coil 12 can be adjusted to regulate the magnetic attraction force of the module 10 on the workpiece. After adjusting the workpiece to the desired position, the power to the coil 12 is cut off, thus securing the workpiece firmly to the magnetic attraction module 10.

[0015] Please refer to Figures 2 to 5 The images show various preferred embodiments of the magnetic module device provided by this utility model, which can be applied to different fields. When applied to a portable lifting device, the device mainly includes one or more magnetic modules 10, a base 20, and a power supply 30.

[0016] The base 20 is not limited in shape; for example, it can be a circular disc or a rectangular block. It is fixedly connected to one or more magnetic modules 10. The base 20 can directly or indirectly provide and control the power to the coil 12. In order to achieve the effect of controlling the magnetic attraction force, the base 20 can be equipped with a control circuit, a push-button switch, or a remote control assembly to control the energization state of the coil 12, thereby operating the magnetic attraction force state of the magnetic module 10.

[0017] The power supply 30 is directly or indirectly connected to the coil 12 to provide power to the coil. The power supply 30 may include a commercially available battery or an external power source.

[0018] In a first preferred embodiment of the present invention, the device may further include a handle and a battery.

[0019] Please refer to Figure 2 In a first preferred embodiment, the base 20 is sized to accommodate one of the magnetic modules 10. The power source 30 is a battery, which can be mounted on the surface of the base 20 and connected to the coil 12 of the magnetic module 10, thereby supplying it with the power required for operation. The base 20 can be made of a lightweight and high-strength material, such as plastic, composite material, or lightweight metal.

[0020] The base 20 is further integrated with the handle to form a portable device. The handle includes a button for switching the power supply status of the magnetic module, thereby selectively generating or eliminating magnetic force.

[0021] During operation, the base 20 can be held close to the workpiece to be moved, and the workpiece will be attracted by the magnetic force generated by the permanent magnet 11. When the workpiece needs to be released, the button on the base 20 is pressed to control the power supply 30 to energize the coil 12. After the coil 12 is energized, it will generate a counter-magnetic force in the opposite direction to the magnetic attraction direction of the permanent magnet 11. Since the counter-magnetic force is at least 80% greater than the magnetic attraction force, the overall magnetic force can be reduced, allowing the workpiece to detach from the magnetic module 10.

[0022] Please refer to Figures 3-5 Furthermore, the magnetic module 10 can be applied to equipment to achieve rapid positioning of the workpiece on different processing equipment, thereby significantly reducing the convenience and stability of positioning and releasing the workpiece on the processing tool. To achieve different functions and allow the magnetic module 10 to be used to fix and grip different workpieces, the device with the magnetic module can be further combined with a device 40, thereby expanding the different application range of the magnetic module 10.

[0023] The device 40 can be a processing device, a robotic arm, or other movable components to handle or adjust the position of workpieces as needed.

[0024] Please refer to Figure 3 In the second preferred embodiment, it includes a plurality of the magnetic modules 10. The base 20 is disc-shaped, and multiple magnetic modules 10 are spaced apart on its surface. The power supply 30 is an external power supply connected to the coil 12, providing the power required for it to be energized.

[0025] In this second preferred embodiment, the base 20 can be connected to a device 40, wherein the device 40 is a robotic arm that can move the magnetic module 10 and provide and control the power to the coil 12.

[0026] During operation, multiple magnetic modules 10 correspond to multiple workpieces to be transported, and the permanent magnet 11 attracts multiple workpieces. When it is necessary to release multiple workpieces, the device 40 controls the power supply 30 to energize the coil 12. After the coil 12 is energized, it generates a counter-magnetic force in the opposite direction to the magnetic attraction of the permanent magnet 11. Since the counter-magnetic force is at least 80% greater than the magnetic attraction force, it can effectively reduce the overall magnetic force to achieve a demagnetizing effect, realizing the automatic detachment of multiple workpieces. This second embodiment is particularly suitable for applications in automated equipment that require multi-point adsorption and rapid release.

[0027] Please refer to Figure 4In a third preferred embodiment, the device includes one or more magnetic modules 10. The base 20 is an elongated plate with multiple magnetic modules 10 evenly spaced on its surface. In the same third preferred embodiment, the power supply 30 is also an external power supply, connected to the coil 12, providing the power required for its operation.

[0028] In this third preferred embodiment, the base 20 can be connected to a device 40, wherein the device 40 is the processing device, the processing device includes a workpiece fixing end and a processing end, the workpiece fixing end is fixedly connected to the base 20, and provides and controls the power of the coil 12, so that the workpiece fixing end and the magnetic module 10 can be tightly connected to magnetically attract a workpiece.

[0029] In use, the permanent magnets 11 of multiple magnetic modules 10 can simultaneously correspond to multiple workpieces, attracting them by generating a magnetic force in one magnetic direction, thereby synchronously or segmentally transporting multiple workpieces. When it is necessary to release a workpiece, the power supply 30 is activated by the device 40, energizing the corresponding coil 12. After the coil 12 is energized, it generates a counter-magnetic force in the opposite magnetic direction to the permanent magnet 11. By adjusting the energizing sequence, the overall magnetic force can be reduced one by one or simultaneously, allowing the workpiece to detach and achieving a rapid release effect.

[0030] This preferred third embodiment is particularly suitable for devices in automated production lines that require multi-point suction and discharge operations.

[0031] In summary, this invention combines a permanent magnet with a controllable electromagnetic coil to achieve a magnetic attraction control function that allows for electric-free adsorption and electric-powered release. This design not only boasts high energy efficiency and power-off safety, but also allows for wide application in diverse scenarios such as handheld handling and automated production lines by modifying the base, power supply method, and connecting equipment. The technical concept of this invention is not limited to the forms disclosed in the above embodiments; all equivalent variations and applications made based on the technical features of this invention should be included within the technical scope of this invention.
