Description

Technical Field

[0001] The present invention relates to the field of magnetic attraction systems, and more particularly, to a controllable automatic replacement magnetic attraction system. Background Art

[0002] Magnetic attraction systems play an indispensable role in modern industry and various daily applications. Especially in the fields of automated production and intelligent device connection, their application scope is constantly expanding. This system uses magnetic force to achieve the adsorption, fixation, and handling of objects, and can complete precise operations in complex environments, with advantages such as high efficiency and convenience. It is widely used in scenarios with high requirements for operation accuracy and efficiency, such as intelligent manufacturing, logistics automated sorting, and electronic device assembly. With the rapid development of technology, higher requirements are put forward for the performance and adaptability of magnetic attraction systems in various industries, promoting the continuous innovation and progress of magnetic attraction technology.

[0003] However, many problems have emerged in the practical application of existing magnetic attraction systems, seriously restricting their further development and application. In terms of the scope of use, the design of traditional magnetic attraction systems is relatively single, making it difficult to meet the diverse needs in different working scenarios. For example, in some special industrial production environments, due to the particularity of the working space, object shape, and material, existing magnetic attraction systems cannot effectively function, resulting in restricted operations and affecting production efficiency. In terms of magnetic force adjustment, most current magnetic attraction systems do not have the function of automatically adjusting the magnetic force and cannot make real-time adjustments according to the actual situation of the adsorbed object. When facing objects of different weights and materials, the fixed magnetic force either cannot provide sufficient adsorption force, causing the object to fall off during handling, or the magnetic force is too large, causing damage to the surface of the object. This problem is particularly prominent when dealing with precision electronic components or fragile items. In addition, the non-replaceability of the magnetic attractor is also a major shortcoming. Once the magnetic attractor fails, the entire magnetic attraction system will be paralyzed. If it is necessary to adapt to new work tasks or repair faults, it often requires replacing the entire system, which is not only time-consuming and laborious but also significantly increases the use cost and maintenance difficulty, seriously affecting the continuity and stability of production.

[0004] In view of this, how to develop a controllable automatic replacement magnetic attraction system that can automatically adjust the magnetic force size, realize the automatic replacement of the magnetic attractor, and has wide applicability has become a key problem that needs to be solved urgently in the relevant industry. This will provide strong support for the efficient application of magnetic attraction systems in more fields and promote the technological upgrading and development of the relevant industry. Summary of the Invention

[0005] According to the above-mentioned technical problems that the existing magnetic adsorption system has limited application range, non-adjustable magnetic force, and non-replaceable magnetic adsorbers, a controllable automatic replacement magnetic adsorption system is provided. The present invention mainly utilizes intelligent control and precise adjustment. The microcontroller in the control device receives the parameter information fed back by the sensor, and automatically adjusts the magnetic force magnitude and position of the magnet according to the preset parameters or external instructions. At the same time, the automatic replacement of the magnetic adsorber is realized by using an automated mechanical structure to meet diverse requirements.

[0006] The technical means adopted by the present invention are as follows:

[0007] A controllable automatic replacement magnetic adsorption system includes a magnet unit module, a sensor module, a control device module, an automatic replacement module, a power supply module, and an interaction interface module;

[0008] The magnet unit module is composed of multiple independent and cooperative magnet units, and multiple magnet units are matrix-layout integrated within the main frame;

[0009] The sensor module is fixed on the main frame through a mounting bracket and is used to detect the magnetic force magnitude, direction, and relative position between the magnet and the adsorbed object;

[0010] The control device module is respectively connected to the sensor module, the magnet unit module, and the automatic replacement module through a data transmission bus;

[0011] The automatic replacement module includes a multi-joint robotic arm composed of several joints, and each joint has a 180° rotation angle and can accurately grasp and release the magnetic adsorber.

[0012] Furthermore, the magnetic adsorption system is also provided with an interaction interface module. The interaction interface module is connected to the control device module through a data interface, and the control device module controls the magnet unit module and the automatic replacement module according to the received information.

[0013] Furthermore, the magnet unit is an electromagnet or a permanent magnet, and the diameter of each magnet unit is 20–50 mm;

[0014] Adjacent magnet units are positioned and connected through a slot and a block. A connecting piece passes through the slot and block on adjacent magnet units to connect multiple magnet units together;

[0015] One end of the L-shaped device is connected to the main frame through a screw, and the other end is fixed on the base to enhance the stability of the magnet unit.

[0016] Furthermore, the sensor module is connected to the control device module through a signal transmission line.

[0017] Further, the control device module is installed on the main frame; the control device module includes a microcontroller, a power supply module, and a circuit board, on which a signal processing chip and electronic components are integrated; the power supply module is respectively connected to the microcontroller and the circuit board. Among them, the microcontroller is the core of the control device module, responsible for analyzing and processing sensor data and coordinating the work of each module. It pre-stores control strategies for different working scenarios and parameter requirements, and can quickly generate corresponding control signals according to the received data and user instructions.

[0018] Further, the power supply module is respectively connected to the sensor module, the control device module, the automatic replacement module, and the magnet unit module through connecting wires to provide power.

[0019] Further, the base is located at the bottom of the magnetic attraction system, the main frame is arranged above the base, and shock-absorbing rubber pads are evenly distributed between the base and the main frame.

[0020] Further, the power supply module is equipped with overload protection and short-circuit protection devices to ensure the electrical safety of the system.

[0021] The processing logic in the system control device module is as follows: Control strategies for different working scenarios and parameter ranges are preset in the microcontroller. After receiving parameters such as the current magnetic field strength H of the magnet, the relative distance d between the object and the magnet, and the estimated weight W of the adsorbed object fed back by the sensor, it will first judge the current working mode. If in the standard adsorption mode, it will compare the current magnetic field strength H with the preset standard magnetic field strength range Hmin - Hmax, and comprehensively adjust the magnetic force of the magnet in combination with the relative distance d between the object and the magnet and the estimated weight W of the adsorbed object. If H is lower than Hmin, and d is within the effective adsorption distance, and W is within a certain range, the microcontroller will issue an instruction to increase the current input to the magnet (for an electromagnet) to enhance the magnetic field strength; if H is higher than Hmax, an instruction will be issued to reduce the current input to weaken the magnetic field strength, so as to achieve precise adjustment of the magnetic force size and ensure that the magnet can stably adsorb the object without affecting the adsorption effect due to too large or too small magnetic force. For the adjustment of the magnet position, if it is judged according to the sensor data that the object deviates from the central adsorption position of the magnet, the microcontroller will send an instruction to the driving device that controls the magnet position according to the deviation direction and distance information, and the driving device will adjust the magnet position through the mechanical structure to make the object in the best adsorption position.

[0033] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments may be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0034] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part rather than all of the embodiments of the present invention. The description of at least one exemplary embodiment is actually only illustrative and in no way restrictive of the present invention and its application or use. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0035] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments of the present invention. As used herein, unless otherwise clearly specified in the context, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of the described features, steps, operations, devices, components and / or their combinations.

[0036] For ease of description, spatial relative terms such as "above...", "on top of...", "on the upper surface of...", "above" etc. may be used herein to describe the spatial positional relationship of one device or feature to another device or feature as shown in the figures. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is inverted, the device described as "above other devices or structures" or "on top of other devices or structures" will then be positioned "below other devices or structures" or "beneath other devices or structures". Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations should be made for the spatial relative descriptions used herein.

[0037] Such as Figures 1-3As shown in the figure, the present invention provides a controllable automatic replacement magnetic attraction system, including a magnet unit module 1, a sensor module 2, a control device module 3, an automatic replacement module 4, a power supply module 5, an aluminum alloy base 6, a shock-absorbing rubber pad 7, a magnetic attraction system main frame 8, a magnet unit 9, a slot and block 10, a high-strength stainless steel connecting piece 11, an L-shaped device 12, a status display area 13, a parameter setting area 14, a touch button area 15, a magnetic force adjustment slider 16, an adsorption time setting 17, a drop-down menu 18, a start button 19, a stop button 20, and a magnetic attraction device replacement button 21.

[0038] The magnet unit module 1 is composed of multiple magnet units 9 arranged in a matrix within the magnetic attraction system main frame 8. The diameter of each magnet unit 9 is between 20 - 50 millimeters, and an electromagnet or a permanent magnet can be selected according to actual working requirements. The adjacent magnet units 9 are initially positioned and connected through the slot and block 10. The design of the slot and block 10 makes the installation and disassembly of the magnet units 9 more convenient and rapid. The high-strength stainless steel connecting piece 11 passes through the slot and block 10 on adjacent magnet units 9, firmly connecting the multiple magnet units 9 together to ensure that the magnet units 9 maintain a stable position and posture during the working process. One end of the L-shaped device 12 is connected to the main frame 8 by screws, and the other end is firmly fixed on the aluminum alloy base 6, further enhancing the stability of the magnet unit 9 and preventing it from displacing during the working process.

[0039] The sensor module 2 is installed on the magnetic attraction system main frame 8 through a special installation bracket, adjacent to the magnet unit module 1, for real-time monitoring of information such as the magnetic field strength around the magnet unit 9 and the relative position between the object and the magnet unit 9, and sending this data to the control device module 3 through a signal transmission line. The information monitored here can be quantified into parameters such as the current magnetic field strength H of the magnet, the relative distance d between the object and the magnet, and the estimated weight W of the adsorbed object, providing a data basis for the subsequent processing of the microcontroller.

[0040] The control device module 3 is installed at a suitable position inside the main frame 8 of the magnetic adsorption system. It includes a microcontroller, a power supply module, and a customized circuit board. Various signal processing chips and electronic components are integrated on the circuit board, which is used to receive the data transmitted by the sensor module 2 and analyze and process the data. The microcontroller is the core of the microcontroller, and various control logics are pre-stored inside it. After receiving parameters such as the current magnetic field strength H of the magnet, the relative distance d between the object and the magnet, and the estimated weight W of the adsorbed object from the sensor, it first determines the current working mode. If it is in the standard adsorption mode, it will compare the current magnetic field strength H with the preset standard magnetic field strength range Hmin - Hmax, and at the same time, comprehensively adjust the magnetic force of the magnet by combining the relative distance d between the object and the magnet and the estimated weight W of the adsorbed object. If H is lower than Hmin, and d is within the effective adsorption distance, and W is within a certain range, the microcontroller will issue an instruction to increase the current input to the magnet (for the electromagnet) to enhance the magnetic field strength; if H is higher, it will issue an instruction to reduce the current input to weaken the magnetic field strength, so as to achieve precise adjustment of the magnetic force size and ensure that the magnet can stably adsorb the object without affecting the adsorption effect due to excessive or too small magnetic force. For the adjustment of the magnet position, if it is judged according to the sensor data that the object deviates from the central adsorption position of the magnet, the microcontroller will send an instruction to the driving device that controls the magnet position according to the deviation direction and distance information, and the driving device will adjust the magnet position through the mechanical structure to make the object in the best adsorption position. At the same time, the control device module 3 is connected to the interaction interface through a data interface, and receives the parameter settings and instruction information input by the user through the interaction interface. When the user adjusts the parameters through operation elements such as the magnetic force adjustment slider 16 in the parameter setting area 14 of the interaction interface, the microcontroller also receives and controls the magnet unit module 1 according to these user inputs.

[0041] The automatic replacement module 4 includes a multi-joint robotic arm. Each joint of the robotic arm can rotate ±180°, and can move and position with an accuracy of ±0.1 mm in three-dimensional space. The automatic replacement module 4 is fixed on the aluminum alloy base 6 through an independent mounting base at the bottom. When the microcontroller in the control device module 3 determines that the magnet unit 9 in the magnet unit module 1 needs to be replaced, it sends a replacement instruction to the automatic replacement module 4, and the automatic replacement module 4 completes the replacement operation of the magnet unit 9 according to the instruction. The user can also manually trigger this operation by clicking the replace magnetizer button 21 in the touch button area 15 of the interaction interface. At this time, the microcontroller receives the instruction and controls the automatic replacement module 4 to perform the replacement action.

[0042] The power supply module 5 is connected to the modules that need to be powered, such as the sensor module 2, the control device module 3, the automatic replacement module 4, and the magnet unit module 1, through connecting wires, and uses a power supply circuit with a voltage stabilizing function to provide stable power supply for each module of the system.

[0043] The aluminum alloy base 6 is located at the bottom of the entire system, providing stable support for the system; the shock-absorbing rubber pads 7 are evenly distributed between the aluminum alloy base 6 and the main frame 8 of the magnetic attraction system, which can effectively reduce the impact of external vibrations on the system.

[0044] The tactile buttons in the interaction interface adopt a tactile feedback design. The high-definition touch screen is 7 inches, with high resolution, clear display, and is convenient for users to view the system status information and set parameters. In the interaction interface, the status display area 13 intuitively presents the status of the system such as normal operation, fault, and the magnetizer being replaced through different color indicator lights; the parameter setting area 14 is provided with a magnetic force adjustment slider 16. When the user drags this slider, the magnetic force can be adjusted. The two ends of the slider are respectively marked with the minimum magnetic force value "0N" and the maximum magnetic force value "50N", and the currently set magnetic force value is also displayed; the adsorption time setting part 17 adopts a text box form, with "adsorption time (s)" marked beside the text box, and preset adsorption time options such as "5s", "10s", "15s", etc. are also provided below; for the drop-down menu 18 of the trigger condition for replacing the magnetizer, after the user clicks, options such as "manual trigger", "magnetic force anomaly trigger", "timed trigger", etc. can be selected from it, and each trigger condition is simply explained beside the menu. In the tactile button area 15, there is a start button 19, and the user can click it to start the system operation; the stop button 20 is used to stop the system operation; the magnetizer replacement button 21, when clicked, can manually trigger the magnetizer replacement operation. Through these tactile buttons and the operation elements on the high-definition touch screen, users can easily set parameters such as the magnetic force size, adsorption time, and trigger conditions for replacing the magnetizer, as well as input instructions such as start, stop, and replace the magnetizer. These parameter and instruction information are transmitted to the control device module 3 through the data interface, and the microcontroller controls the magnet unit module 1, the automatic replacement module 4, etc. accordingly based on the received information.

[0045] Furthermore, the special installation bracket of the sensor module 2 is made of high-strength aluminum alloy material, which not only ensures the installation stability but also reduces the overall weight.

[0046] Furthermore, the circuit board of the control device module 3 adopts a multi-layer design, which improves the circuit integration and anti-interference ability.

[0047] Furthermore, the grasping device of the automatic replacement module 4 adopts a pneumatic clamping structure, which has the characteristics of large clamping force and fast response speed.

[0048] Furthermore, the power supply module 5 is equipped with overload protection and short-circuit protection functions to ensure the electrical safety of the system.

[0049] Furthermore, the slot and block 10 are made of high-strength engineering plastic, which has good wear resistance and corrosion resistance, and can ensure a long-term stable connection effect.

[0050] The working process of the present invention is as follows:

[0051] The power supply module 5 supplies power to each module, enabling the system to enter the initial working state;

[0052] The sensor module 2 continuously detects the magnetic field intensity around the magnet unit 9 in the magnet unit module 1 and the information on the relative position between the object and the magnet unit 9, and sends these data in the form of quantified parameters such as the current magnetic field intensity H of the magnet, the relative distance d between the object and the magnet, and the estimated weight W of the adsorbed object to the control device module 3;

[0053] The microcontroller in the control device module 3 analyzes and processes the data to determine whether the working state of the current magnet unit module 1 meets the working requirements;

[0054] If it is necessary to adjust the working state of the magnet unit module 1, the user can also directly adjust the relevant parameters through operation elements such as the magnetic force adjustment slider 16 in the parameter setting area 14 of the interaction interface. The microcontroller in the control device module 3 receives and sends a control signal to the magnet unit module 1 to achieve the control of the adsorption force;

[0055] If it is determined that the magnet unit 9 in the magnet unit module 1 needs to be replaced, the control device module 3 sends a replacement instruction to the automatic replacement module 4, and the automatic replacement module 4 completes the replacement operation of the magnet unit 9 according to the instruction; the user can also manually trigger this operation by clicking the magnet replacement button 21 in the touch button area 15 of the interaction interface;

[0056] The whole process repeats continuously to achieve the continuous and stable operation of the system.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
