Description

Technical Field

[0001] This invention relates to the field of iron filings cleaning technology, and in particular to an omnidirectional mobile magnetic iron filings recycling trolley and its usage method. Background Technology

[0002] In industrial workshops such as machining, casting, and grinding, the scattering of iron filings is common. This not only damages the cleanliness of the production environment but also easily scratches equipment, interferes with the positioning of automated equipment, and even causes safety accidents such as slips and falls. The efficient cleaning and recycling of iron filings has become an urgent problem to be solved in the industry. Currently, related iron filings handling technologies have many drawbacks. Manual sweeping and handheld magnetic rods are inefficient, generate dust, and suffer from incomplete cleaning and significant safety hazards. Traditional magnetic trolleys also have poor adaptability and cleaning efficiency due to design flaws in their wheels and magnetic structure.

[0003] For example, Chinese patent application CN119056518A discloses a device for recycling shavings from fused brick cutting. This device requires pre-treatment by crushing the shavings before they can be attracted. The magnetic suction device has a fixed height and area, and the ordinary casters can only turn it. The shavings still need to be passively collected by gravity, which is easy to leave residues and has low efficiency. It is only suitable for centralized processing of shavings at fixed locations. Another example is Chinese patent application CN114147628A, which discloses a combined processing device for polishing the joints of cargo truck bodies. Its shavings recycling is only an auxiliary function of the polishing process. It relies on airflow and waterflow to assist in the collection and transportation of shavings. The magnetic screening structure is a fixed design without adjustment function, and it uses an ordinary directional moving vehicle body. It can only be adapted to the polishing operation area and cannot independently complete the cleaning of shavings throughout the workshop.

[0004] In summary, neither of the two types of specialized equipment can meet the needs of mobile iron filings cleaning in complex workshop environments. The existing technologies as a whole are insufficient to meet the requirements of modern industrial workshops for flexibility, efficiency, and automation in iron filings cleaning. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies, such as difficulty in adapting to complex sites, poor flexibility, and low work efficiency, and to provide an omnidirectional mobile magnetic scrap recycling trolley and its usage method.

[0006] In a first aspect, the present invention provides an omnidirectional mobile magnetic scrap recycling trolley to solve the above-mentioned technical problems, comprising a mobile frame, a strong magnetic roller, and a control box; the bottom of the mobile frame is provided with four sets of omnidirectional wheels, and each set of omnidirectional wheels is correspondingly equipped with a DC geared motor A; the strong magnetic roller is located at the center of the mobile frame, and both ends of the strong magnetic roller shaft are rotatably connected to sliders via bearings, the sliders are slidably connected to a vertical slide rail, and the top of the vertical slide rail is perpendicularly connected to the side of the mobile frame; both ends of the strong magnetic roller are respectively provided with magnetic roller lifting devices, the magnetic roller lifting devices are installed at the top of the vertical slide rail, and the magnetic roller lifting device is used to lift the magnetic roller. The working end of the lowering device is connected to the slider, and the two magnetic roller lifting devices can operate synchronously and drive the strong magnetic roller to rise and fall; one end of the rotating shaft rotates through the corresponding slider and is connected to the magnetic roller drive motor, which is mounted on the corresponding slider; the inside of the mobile frame is provided with a material picking box located below the side of the strong magnetic roller, and the outer edge of the material picking box is tightly tangent to the outer wall of the strong magnetic roller; the control box includes a remote control module and a lithium battery power module integrated therein, and the remote control module is electrically connected to the magnetic roller lifting device, the magnetic roller drive motor and the DC geared motor A respectively, and is powered by the lithium battery power module.

[0007] This trolley integrates the core structures of movement, magnetic attraction, lifting, collection, and control into one unit, realizing automated operation of iron filings cleaning and reducing manual intervention. The synchronous operation of the magnetic roller lifting device ensures smooth lifting of the strong magnetic roller, and the tangential design on the lower side of the material box enables efficient scraping and collection of iron filings. The omnidirectional wheels and independent drive motors make the trolley move more flexibly. The overall structure is compact and adaptable to the complex iron filings cleaning scenarios in industrial workshops.

[0008] A further improvement of the present invention is that the magnetic roller drive motor includes a DC geared motor B, the DC geared motor B is mounted on the corresponding slider, the DC geared motor B is electrically connected to the remote control module, and the output shaft of the DC geared motor B is connected to the end of the rotating shaft that rotates through the corresponding slider.

[0009] DC geared motor B can provide stable torque and speed, ensuring uniform rotation of the strong magnetic roller and improving the stability of iron filings adsorption; the motor is directly mounted on the slider and connected to the rotating shaft at close range, reducing power transmission loss, and rises and falls synchronously with the slider, resulting in a more compact structural layout and eliminating the need for additional transmission and telescopic structures.

[0010] A further improvement of the present invention is that the magnetic roller lifting device includes a TT micro motor and a drive screw. The TT micro motor is electrically connected to the remote control module. The output shaft of the TT micro motor is connected to the top of the drive screw. The bottom of the drive screw is threaded into a threaded hole on the slider. The TT micro motor can drive the drive screw to rotate in both directions, thereby driving the slider to rise and fall along the vertical track, and thus adjusting the vertical height of the strong magnetic roller.

[0011] TT micro motors feature high control precision and low operating noise. The threaded transmission of the drive screw is smooth and backlash-free. The height of the strong magnetic roller can be precisely adjusted according to the thickness of the iron filings and the flatness of the ground. This ensures thorough adsorption of iron filings of different thicknesses while avoiding wear caused by direct contact between the strong magnetic roller and the ground, effectively extending the service life of the equipment.

[0012] A further improvement of the present invention is that a camera with a built-in AP hotspot is provided at the end of the mobile frame facing its forward direction, and the camera is electrically connected to the remote control module.

[0013] The camera setup fills in the blind spots for remote operators, enabling real-time visualization of the work site. This allows operators to accurately determine the location of scattered iron filings and the movement path of the trolley, improving the precision of trolley movement and iron filings removal. The built-in AP hotspot ensures more stable signal transmission, eliminating the need for external networks and adapting to the industrial environment of the workshop, while also enhancing the safety of remote operations.

[0014] A further improvement of the present invention is that the remote control module integrates a PS2 wireless transmitter and receiver module and an Arduino microcontroller. The PS2 wireless transmitter and receiver module is electrically connected to the Arduino microcontroller based on the SPI communication protocol. The Arduino microcontroller is electrically connected to the magnetic roller lifting device, the magnetic roller drive motor, the camera, and the DC geared motor A, respectively.

[0015] The SPI communication protocol features high transmission speed and high signal stability, ensuring rapid parsing and transmission of remote control signals; the PS2 wireless transmitter and receiver module enables wireless remote control, freeing users from the constraints of the workspace; the Arduino microcontroller serves as the control core, enabling centralized management of all execution components, enhancing the coordination of actions among components, improving the intelligence level of the equipment, and simplifying the operation process while reducing the difficulty of manual operation.

[0016] A further improvement of the present invention is that the lithium battery power module is a rechargeable power supply capable of outputting 5V and 3.3V DC voltages to provide working power for the magnetic roller drive motor, magnetic roller lifting device, control box, camera and DC geared motor A.

[0017] The rechargeable design enables the recycling of power, eliminating the need for frequent power supply replacements and reducing equipment operating costs. It also adapts to the mobile operation needs of workshops without external power sources. The dual-voltage stable output can meet the power supply requirements of different components, ensuring the normal and stable operation of each electrical component, avoiding equipment failure or malfunction due to voltage instability, and improving the operational reliability of the equipment.

[0018] A further improvement of the present invention is that the material receiving box has a tipping bucket structure, including a support frame and a hopper, the support frame is connected to a mobile frame, the hopper is rotatably mounted on the support frame, and the upper edge of the hopper is tightly tangent to the outer wall of the strong magnetic roller.

[0019] The design of the hopper's upper edge being tightly tangent to the strong magnetic roller can completely scrape off the iron filings from the outer wall of the roller, leaving no iron filings and improving the iron filings collection efficiency; the tipping bucket structure makes the unloading operation simple and quick, eliminating the need for manual stripping of iron filings from the roller, greatly reducing the labor intensity of operators, and the rotating hopper design ensures that there are no dead angles during unloading.

[0020] A further improvement of the present invention is that the mobile frame is made of high-strength aluminum alloy material, and the omnidirectional wheels are Mecanum wheels.

[0021] High-strength aluminum alloy material is lightweight, high-strength, and has good rust and corrosion resistance. It not only reduces the overall weight of the trolley and improves its mobility, but also adapts to the harsh working environment of humid and dusty workshops, effectively extending the service life of the mobile frame. The omnidirectional mobility of the Mecanum wheels allows the trolley to easily shuttle through equipment gaps, narrow passages, and other areas that are difficult for conventional equipment to reach in industrial workshops, improving the adaptability of the equipment to complex workshop sites and achieving full-area cleaning of iron filings.

[0022] A further improvement of the present invention is that the output shaft of the DC geared motor B is fixedly positioned and fastened to the rotating shaft of the strong magnetic roller by positioning screws, and the DC geared motor B is a unidirectional rotation drive.

[0023] The positioning screws provide a simple and reliable fastening method, effectively ensuring the tightness of the connection between the output shaft and the rotating shaft, avoiding slippage and offset during transmission, and improving power transmission efficiency and stability. The unidirectional rotation drive of the DC geared motor B keeps the rotation direction of the strong magnetic roller fixed, ensuring that the iron filings always move in a direction tangential to the material collection box, preventing the adsorbed iron filings from falling off due to the roller reversal, and improving the stability of iron filings collection.

[0024] Secondly, the present invention also provides an operating method for an omnidirectional mobile magnetic scrap recycling trolley, characterized by comprising the following steps: S1. Before operation, check the tightness of the connections of each part of the trolley, ensure that the lithium battery power module is fully charged, turn on the power of the control box, complete the signal pairing between the camera and the remote control module, and realize the real-time transmission of the operation site image. S2. Start the magnetic rotation mechanism. Start the magnetic roller drive motor through the remote control module to drive the strong magnetic roller to rotate in one direction at a uniform speed, and enter the state where iron filings are to be attracted. S3. Move to the work area, remotely control the DC geared motor A to drive the Mecanum wheel to achieve 360° omnidirectional movement of the trolley, and combine the real-time image of the camera to accurately move the trolley to the work area where iron filings are scattered. S4. Adjust the magnetic suction height. Based on the thickness of the iron filings and the flatness of the ground, remotely start the magnetic roller lifting device. The TT micro motor drives the drive screw to rotate forward and backward, adjusting the vertical height of the strong magnetic roller above the ground. S5. Iron filings adsorption and collection: When the trolley moves in the working area, the strong magnetic roller adsorbs iron filings. The iron filings are scraped off when they reach the point tangent to the material box as the roller rotates, and fall into the hopper under the action of gravity to complete the automatic collection. S6. Finish the work and unload the material. After cleaning, remotely turn off the magnetic roller drive motor, move the trolley to the designated unloading position, rotate the tipping hopper to unload the material, and finally turn off the power to the control box.

[0025] The standardized operating procedures make this trolley easy to operate and understand, allowing operators to quickly get started without professional training, thus lowering the barrier to entry for the equipment. The smooth transition between each step enables remote control of the entire process of scrap cleaning from preparation to unloading, significantly improving the efficiency of scrap cleaning in industrial workshops. The standardized operating procedures reduce equipment failures caused by misoperation, extend the service life of the equipment, and achieve efficient scrap cleaning and recycling, meeting the automated and efficient cleaning needs of modern industrial workshops.

[0026] As can be seen from the above technical solutions, the beneficial effects of the present invention are: 1. This trolley achieves 360° omnidirectional movement through the combination of Mecanum wheels and an independent DC geared motor, allowing it to easily navigate between equipment gaps and narrow passages in the workshop, achieving comprehensive cleaning of metal filings. The mobile frame is made of high-strength aluminum alloy, which combines lightweight, high strength, and rust and corrosion resistance, enhancing mobility and adapting to the complex working environment of a humid and dusty workshop. Equipped with a front-end visual camera, it can also compensate for blind spots in remote control and improve operational accuracy.

[0027] 2. This trolley can precisely adjust the vertical height of the strong magnetic roller through the magnetic roller lifting device, and can flexibly adapt to the thickness of the iron filings and the flatness of the ground, ensuring thorough adsorption of iron filings while avoiding wear caused by contact between the roller and the ground; the design of the tipping bucket material box being tightly tangent to the roller can realize automatic scraping and collection of iron filings without residue, and the tipping bucket structure also makes the unloading operation simple, greatly reducing the labor intensity of manually stripping iron filings.

[0028] 3. This vehicle achieves centralized and coordinated control of all components by integrating a wireless remote control module and a microcontroller. The operation process is simple and easy to understand, reducing the operating threshold. The rechargeable lithium battery power supply can output dual-adaptive voltages to provide stable power to all components, eliminating the limitation of external power supply and adapting to the needs of mobile operations in the workshop. The standardized operation process can also reduce failures caused by misoperation, improve the automation and efficiency of iron filings cleaning, and meet the cleaning needs of modern industrial workshops.

[0038] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0039] Example 1: Refer to Figure 1-7 This embodiment provides an omnidirectional mobile magnetic scrap recycling trolley, including a mobile frame 1, a strong magnetic roller 2, and a control box 6. The bottom of the mobile frame 1 is provided with four sets of omnidirectional wheels 11, and each set of omnidirectional wheels 11 is correspondingly equipped with a DC geared motor A12. The strong magnetic roller 2 is located at the center inside the mobile frame 1. Both ends of the shaft 21 of the strong magnetic roller 2 are rotatably connected to sliders 42 via bearings. The sliders 42 are slidably connected to a vertical slide rail 43, and the top of the vertical slide rail 43 is perpendicularly connected to the side of the mobile frame 1. Magnetic roller lifting devices 5 are respectively provided at both ends of the strong magnetic roller 2. The magnetic roller lifting devices 5 are installed on the top of the vertical slide rail 43. The operation of the magnetic roller lifting devices 5... The end is connected to the slider 42, and the two magnetic roller lifting devices 5 can move synchronously and drive the strong magnetic roller 2 to rise and fall; one end of the rotating shaft 21 rotates through the corresponding slider 42 and is connected to the magnetic roller drive motor 4, which is installed on the corresponding slider 42; the inside of the mobile frame 1 is provided with a material picking box 3 located below the side of the strong magnetic roller 2, and the outer edge of the material picking box 3 is tightly tangent to the outer wall of the strong magnetic roller 2; the control box 6 includes a remote control module 61 and a lithium battery power module 62 integrated inside it. The remote control module 61 is electrically connected to the magnetic roller lifting device 5, the magnetic roller drive motor 4 and the DC geared motor A12 respectively, and is powered by the lithium battery power module 62.

[0040] The mobile frame 1 serves as the overall load-bearing foundation. Its four sets of omnidirectional wheels 11 are independently driven by their respective DC geared motors A12, enabling the trolley's movement. The strong magnetic roller 2 is connected to the slider 42 via a rotating shaft 21 and a vertical slide rail 43. The magnetic roller lifting device 5, mounted on top of the vertical slide rail 43, can lift the slider 42, thus adjusting the vertical height of the strong magnetic roller 2. The two magnetic roller lifting devices 5 operate synchronously to ensure smooth roller lifting. The magnetic roller drive motor 4, mounted on the slider 42 and connected to the rotating shaft 21, drives the strong magnetic roller 2 to rotate and attract iron filings. The material collection box 3, located below the side of the strong magnetic roller 2, is tangentially attached to the outer wall of the roller, scraping off and collecting iron filings from the roller. The remote control module 61 in the control box 6 is electrically connected to the magnetic roller lifting device 5, the magnetic roller drive motor 4, and the DC geared motor A12, enabling remote control of each component. The lithium battery power module 62 provides power to all electrically connected components.

[0041] This trolley integrates the core structures of movement, magnetic attraction, lifting, collection, and control into one unit, realizing automated operation of iron filings cleaning and reducing manual intervention; the magnetic roller lifting device 5 operates synchronously to ensure the smooth lifting of the strong magnetic roller 2; the tangential design of the material box 3 on the lower side enables efficient scraping and collection of iron filings; the omnidirectional wheel 11, together with an independent drive motor, makes the trolley move more flexibly; the overall structure is compact and adaptable to the complex iron filings cleaning scenarios in industrial workshops.

[0042] Specifically, refer to Figure 2 and Figure 6 The magnetic roller drive motor 4 includes a DC geared motor B41, which is mounted on the corresponding slider 42. The DC geared motor B41 is electrically connected to the remote control module 61, and the output shaft of the DC geared motor B41 is connected to the end of the rotating shaft 21 that rotates through the corresponding slider 42.

[0043] The magnetic roller drive motor 4 is specifically set as a DC geared motor B41, which is mounted on the slider 42 and electrically connected to the remote control module 61. It can be started and stopped by the command sent by the remote control module 61. The output shaft of the DC geared motor B41 is directly connected to the end of the rotating shaft 21 of the strong magnetic roller 2, and the power is transmitted to the rotating shaft 21, thereby driving the strong magnetic roller 2 to rotate.

[0044] The DC geared motor B41 can provide stable torque and speed, ensuring that the strong magnetic roller 2 rotates at a uniform speed and improving the stability of iron filings adsorption. The motor is directly mounted on the slider 42 and connected to the rotating shaft 21 at close range, reducing power transmission loss. It also rises and falls synchronously with the slider 42, making the structure more compact and eliminating the need for an additional transmission telescopic structure.

[0045] Specifically, refer to Figure 2 and Figure 7The magnetic roller lifting device 5 includes a TT micro motor 51 and a drive screw 52. The TT micro motor 51 is electrically connected to the remote control module 61. The output shaft of the TT micro motor 51 is connected to the top of the drive screw 52. The bottom of the drive screw 52 is threaded into a threaded hole on the slider 42. The TT micro motor 51 can drive the drive screw 52 to rotate in both directions, thereby driving the slider 42 to rise and fall along the vertical slide rail 43, thus adjusting the vertical height of the strong magnetic roller 2.

[0046] The magnetic roller lifting device 5 consists of a TT micro motor 51 and a drive screw 52. The TT micro motor 51 is electrically connected to the remote control module 61. After receiving the remote control command, it drives the drive screw 52 to rotate in both directions. The bottom of the drive screw 52 is threadedly engaged with the threaded hole of the slider 42. The rotational motion of the screw is converted into the linear lifting motion of the slider 42 along the vertical slide 43, which ultimately drives the strong magnetic roller 2 to achieve precise vertical height adjustment.

[0047] The TT micro motor 51 features high control precision and low operating noise. The threaded transmission of the drive screw 52 is smooth and backlash-free. It can precisely adjust the height of the strong magnetic roller 2 according to the thickness of the iron filings and the flatness of the ground. This ensures thorough adsorption of iron filings of different thicknesses and avoids wear caused by direct contact between the strong magnetic roller 2 and the ground, effectively extending the service life of the equipment.

[0048] Specifically, referring to step 3, the end of the mobile frame 1 facing its forward direction is equipped with a camera 7 with a built-in AP hotspot, and the camera 7 is electrically connected to the remote control module 61.

[0049] A camera 7 with a built-in AP hotspot is installed at the end of the mobile frame 1 in the forward direction and electrically connected to the remote control module 61. The camera 7 captures real-time images of the work site and transmits the image signal to the remote control module 61 through the electrical connection, so as to realize the operator's remote visual monitoring of the work site.

[0050] The camera 7 compensates for the blind spots in the operator's remote control, enabling real-time visualization of the work site. This allows operators to accurately determine the location of scattered iron filings and the movement path of the trolley, improving the accuracy of trolley movement and iron filings cleaning. The built-in AP hotspot makes signal transmission more stable, eliminating the need for external networks and adapting to the industrial environment of the workshop, while also enhancing the safety of remote operations.

[0051] Specifically, the remote control module 61 integrates a PS2 wireless transmitter and receiver module and an Arduino microcontroller. The PS2 wireless transmitter and receiver module is electrically connected to the Arduino microcontroller based on the SPI communication protocol. The Arduino microcontroller is electrically connected to the magnetic roller lifting device 5, the magnetic roller drive motor 4, the camera 7, and the DC geared motor A12.

[0052] The remote control module 61 integrates a PS2 wireless transmitter / receiver module and an Arduino microcontroller. The PS2 wireless transmitter / receiver module and the Arduino microcontroller are electrically connected based on the SPI communication protocol. The PS2 module is responsible for transmitting and receiving external wireless remote control signals and transmitting the signals to the Arduino microcontroller. After the microcontroller analyzes the signals, it sends action commands to the magnetic roller lifting device 5, the magnetic roller drive motor 4, the camera 7, and the DC geared motor A12, thereby realizing centralized wireless control of each component.

[0053] The SPI communication protocol features high transmission speed and high signal stability, ensuring rapid parsing and transmission of remote control signals; the PS2 wireless transmitter and receiver module enables wireless remote control, freeing users from the constraints of the workspace; the Arduino microcontroller serves as the control core, enabling centralized management of all execution components, enhancing the coordination of actions among components, improving the intelligence level of the equipment, and simplifying the operation process while reducing the difficulty of manual operation.

[0054] Specifically, refer to Figure 3 The lithium battery power module 62 is a rechargeable power supply that can output 5V and 3.3V DC voltage to provide working power for the magnetic roller drive motor 4, magnetic roller lifting device 5, control box 6, camera 7 and DC geared motor A12.

[0055] The lithium battery power module 62 is configured as a rechargeable power supply, which can stably output two DC voltages: 5V and 3.3V. According to the different voltage power supply requirements of the magnetic roller drive motor 4, magnetic roller lifting device 5, control box 6, camera 7, and DC geared motor A12, it provides suitable and stable working power for each electrical component, and can be recharged and used repeatedly.

[0056] The rechargeable design enables the recycling of power, eliminating the need for frequent power supply replacements and reducing equipment operating costs. It also adapts to the mobile operation needs of workshops without external power sources. The dual-voltage stable output can meet the power supply requirements of different components, ensuring the normal and stable operation of each electrical component, avoiding equipment failure or malfunction due to voltage instability, and improving the operational reliability of the equipment.

[0057] Specifically, refer to Figure 5 The material box 3 is a tipping bucket structure, including a support frame 31 and a hopper 32. The support frame 31 is connected to the mobile frame 1. The hopper 32 is rotatably mounted on the support frame 31, and the upper edge of the hopper 32 is tightly tangent to the outer wall of the strong magnetic roller 2.

[0058] The material collection box 3 is designed as a tipping bucket structure, consisting of a support frame 31 and a hopper 32. The support frame 31 provides fixed support for the hopper 32, which can rotate around the support frame 31. The upper edge of the hopper 32 is tightly tangent to the outer wall of the strong magnetic roller 2. When the iron filings attracted by the rotating strong magnetic roller 2 move to the tangent position, they are scraped off by the upper edge of the hopper 32 and fall into the hopper 32 under the action of gravity to complete the collection. When unloading, rotating the hopper 32 can pour out the iron filings inside.

[0059] The close tangent design between the upper edge of the hopper 32 and the strong magnetic roller 2 can completely scrape off the iron filings on the outer wall of the roller, leaving no iron filings residue and improving the iron filings collection efficiency. The tipping bucket structure makes the unloading operation simple and quick, eliminating the need for manual stripping of iron filings from the roller, greatly reducing the labor intensity of operators. In addition, the rotating setting of the hopper 32 ensures that there are no dead angles for unloading.

[0060] Specifically, refer to Figure 3 The mobile frame 1 is made of high-strength aluminum alloy, and the omnidirectional wheel 11 is a Mecanum wheel.

[0061] The mobile frame 1 is made of high-strength aluminum alloy material. The mechanical properties of the material are used to ensure the load-bearing strength of the frame while reducing the weight of the frame. The omnidirectional wheels 11 are specifically set as Mecanum wheels. Through the differential operation of four sets of Mecanum wheels, the omnidirectional movement of the car, such as forward, backward, lateral movement and 360° rotation, can be realized.

[0062] High-strength aluminum alloy material is lightweight, high-strength, and has good rust and corrosion resistance. It not only reduces the overall weight of the trolley and improves its mobility, but also adapts to the harsh working environment of the workshop, which is humid and dusty, effectively extending the service life of the mobile frame 1. The omnidirectional mobility of the Mecanum wheels allows the trolley to easily shuttle through the gaps between equipment and narrow passages in the industrial workshop, which are difficult for conventional equipment to reach. This improves the adaptability of the equipment to complex workshop sites and enables the complete cleaning of iron filings.

[0063] Specifically, refer to Figure 6 The output shaft of the DC geared motor B41 is fixed to the rotating shaft 21 of the strong magnetic roller 2 by positioning screws 44, and the DC geared motor B41 is a unidirectional rotation drive.

[0064] The output shaft of the DC geared motor B41 and the rotating shaft 21 of the strong magnetic roller 2 are fixed by positioning screws 44 to achieve circumferential and axial fixation of the output shaft and the rotating shaft 21, ensuring the coaxiality of power transmission. The DC geared motor B41 is set to unidirectional rotation drive, driving the strong magnetic roller 2 to always rotate in a fixed direction, and working with the material box 3 to complete the scraping and collection of iron filings.

[0065] The positioning screw 44 has a simple and reliable positioning and fastening method, which can effectively ensure the tightness of the connection between the output shaft and the rotating shaft 21, avoid slippage and offset during transmission, and improve the efficiency and stability of power transmission. The unidirectional rotation drive of the DC geared motor B41 keeps the rotation direction of the strong magnetic roller 2 fixed, ensuring that the iron filings always move in a direction tangential to the material box 3, avoiding the falling off of the adsorbed iron filings due to the roller reversal, and improving the stability of iron filings collection.

[0066] Example 2: Based on Example 1, this example provides an operation method for an omnidirectional mobile magnetic scrap recycling cart, characterized by the following steps: S1. Before operation, check the tightness of the connections of each part of the trolley, ensure that the lithium battery power module 62 is fully charged, turn on the power of the control box 6, complete the signal pairing between the camera 7 and the remote control module 61, and realize the real-time transmission of the operation site image. S2. Start the magnetic rotation mechanism. Start the magnetic roller drive motor 4 through the remote control module 61 to drive the strong magnetic roller 2 to rotate in one direction at a uniform speed, and enter the state of waiting to attract iron filings. S3. Move to the work area, remotely control the DC geared motor A12 to drive the Mecanum wheel to achieve 360° omnidirectional movement of the trolley, and combine the real-time image of the camera 7 to accurately move the trolley to the work area where iron filings are scattered. S4. Adjust the magnetic suction height. Based on the thickness of the iron filings and the flatness of the ground, remotely start the magnetic roller lifting device 5. The TT micro motor 51 drives the drive screw 52 to rotate forward and backward, adjusting the vertical height of the strong magnetic roller 2 and the ground. S5. Iron filings adsorption and collection: When the trolley moves in the working area, the strong magnetic roller 2 adsorbs iron filings. The iron filings are scraped off when they reach the point where they are tangent to the material box 3 as the roller rotates. They fall into the hopper 32 under the action of gravity to complete the automatic collection. S6. Finish the work and unload the material. After cleaning, remotely turn off the magnetic roller drive motor 4, move the trolley to the designated unloading position, rotate the tipping hopper 32 to unload the material, and finally turn off the power to the control box 6.

[0067] Following standardized steps including pre-operation preparation, activation of the magnetic rotating mechanism, movement to the work area, adjustment of the magnetic height, iron filings adsorption and collection, and unloading at the end of the operation, the remote control module 61 sequentially controls the coordinated actions of each component of the trolley. First, the equipment is debugged and the signal is paired. Then, the magnetic rotating function is activated, and the trolley is precisely moved to the area where iron filings are scattered. After adjusting the appropriate magnetic height, the iron filings are automatically adsorbed and collected. Finally, the equipment is shut down and the iron filings are unloaded, forming a complete iron filings cleaning operation process.

[0068] The standardized operating procedures make this trolley easy to operate and understand, allowing operators to quickly get started without professional training, thus lowering the barrier to entry for the equipment. The smooth transition between each step enables remote control of the entire process of scrap cleaning from preparation to unloading, significantly improving the efficiency of scrap cleaning in industrial workshops. The standardized operating procedures reduce equipment failures caused by misoperation, extend the service life of the equipment, and achieve efficient scrap cleaning and recycling, meeting the automated and efficient cleaning needs of modern industrial workshops.
