[0002] Mechatronics equipment is a product of the deep integration of mechanical technology, electronic technology, control technology and information technology. It is widely used in many fields such as industry, transportation, medical care, and home. Common mechatronics equipment includes industrial robots, CNC machine tools, and automated production lines.

[0003] During the use of mechatronics equipment, regular safety inspections are required. This necessitates checking the equipment's appearance, functions, and operational status. However, when inspecting the appearance, the equipment's generally large size makes observation of the bottom and top less than ideal. Traditionally, personnel hold an inspection mirror for assistance. However, the mirror's fixed size makes observation of higher or deeper positions very inconvenient. Furthermore, prolonged holding without support can easily cause arm fatigue, affecting inspection duration and reducing overall efficiency. Therefore, the method is not ideal and has room for improvement. Utility Model Content

These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0018] According to an embodiment of the present invention, a mechatronic retractable safety inspection device is provided.

[0019] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1 , Figure 3 and Figure 4As shown, a mechatronic retractable safety inspection device according to an embodiment of the present invention includes a mounting base 1 and a movable wheel 15. A rotating groove 13 is formed at the center of the top of the mounting base 1. A fixed arm 2 is rotatably connected inside the rotating groove 13. A movable arm 9 is slidably connected inside the fixed arm 2. An inspection block 11 is welded to one end of the movable arm 9. Fixed plates 10 are symmetrically welded to the bottom of the inspection block 11 and the bottom of the mounting base 1. The movable wheel 15 is rotatably connected between the fixed plates 10. Support frames 16 are symmetrically welded to both sides of the movable wheel 15 on the surface of the fixed plates 10. The bottom of the support frames 16 is flush with the bottom of the movable wheel 15. A circular rotating groove 13 is formed at the center of the top of the mounting base 1. A deep groove ball bearing is installed on the shaft. The outer ring of the bearing is interference-fitted with the rotating groove 13, and the inner ring is welded to the bottom end of the fixed arm 2 to form a rotating pair. The fixed arm 2 is a hollow rectangular steel tube. The bottom end is inserted into the inner ring of the bearing and fully welded to ensure that the fixed arm 2 can rotate flexibly around the rotating groove 13, realizing the angle switching between "horizontally pointing to the bottom of the equipment" and "vertically pointing to the top of the equipment". A rectangular slide rail is opened along the length of the fixed arm 2. The groove wall is polished. The movable arm 9 is a solid rectangular steel rod that matches the slide rail. The cross-sectional dimension is slightly smaller than the slide rail. The movable arm 9 is inserted into the slide rail from the end of the fixed arm 2 away from the mounting base 1 to form a sliding fit. The movable arm 9 can reciprocate along the slide rail. By adjusting the extension length, it can adapt to different depths, such as the bottom of the equipment or the top of the equipment. To meet the inspection needs at high locations, the movable arm 9 has a fully welded inspection block 11 at its end away from the fixed arm 2. The inspection block 11 is a cubic steel block with a pre-drilled mounting hole for a camera 12 at the top and two sets of L-shaped steel plates 10 symmetrically welded to the bottom, perpendicular to the inspection block 11, providing a mounting base for the movable wheels 15. The rotation of the fixed arm 2 enables switching between multiple scenarios, such as "horizontal inspection of the bottom of the equipment," "vertical inspection of the top of the equipment," and "tilted inspection of the sides of the equipment," overcoming the limitation of traditional inspection mirrors that "can only inspect horizontally or at close range," thus increasing the inspection coverage. The telescopic movement of the movable arm 9 can extend the inspection block 11 to different ranges, eliminating the need for personnel to bend over and crawl under the equipment or climb to high places, avoiding safety hazards such as bumps and falls, while also expanding the inspection area. Check the depth / height; the two sets of fixing plates 10 at the bottom of the inspection block 11 have the same structure as the two sets of fixing plates 10 at the bottom of the mounting base 1. Each set of fixing plates 10 is rotatably connected to the moving wheel 15 by a pin shaft; the surface of the fixing plates 10 on both sides of the moving wheel 15 is symmetrically welded with support frames 16. The bottom of the support frame 16 is cut into a flat surface, and the bottom of the support frame 16 is completely consistent with the bottom of the moving wheel 15, ensuring that when the moving wheel 15 touches the ground, the support frame 16 simultaneously contacts the ground, forming a "double wheel + double frame" support structure; when the fixed arm 2 inspects the bottom of the equipment horizontally, the moving wheel 15 + support frame 16 at the bottom of the mounting base 1 and the moving wheel 15 + support frame 16 at the bottom of the inspection block 11 contact the ground together, forming a four-point support, and the equipment as a whole has no risk of tipping over;When the device is pushed, the moving wheels 15 roll to drive the entire device to move, while the support frame 16 only plays an auxiliary balancing role. There is no sliding friction, so it does not affect the moving efficiency. The support frame 16 can share the weight of the device, preventing the moving wheels 15 from deforming due to long-term independent load-bearing, and at the same time reducing the "lifting force" when pushed by personnel, making operation easier. The moving wheels 15 facilitate adjusting the inspection position around large electromechanical equipment, such as CNC machine tools and industrial robots, without the need for frequent device movement, thus improving moving efficiency and adapting to continuous inspection of multiple devices in the workshop. The four-point support structure means that the device does not require personnel to hold and bear the weight during inspection; only a slight grip on the guide is needed, avoiding the fatigue caused by the "arm hanging in the air" of traditional handheld inspection mirrors and reducing operational intensity.

[0020] Please refer to Figure 1 and Figure 2 As shown, a groove 6 is provided on one side of the top of the fixed arm 2. A sliding plate 5 is slidably connected inside the groove 6. A display screen 4 is installed on the top of the sliding plate 5. Handles 3 are symmetrically installed on both sides of the fixed arm 2. A rectangular groove 6 is provided along the length of the top of the fixed arm 2, and its width is adapted to the sliding plate 5. Guide grooves are provided on both sides of the inner wall of the groove 6 to prevent the sliding plate 5 from shifting. The sliding plate 5 is a rectangular plastic plate made of insulating material to avoid electrical interference. The bottom has a protrusion that matches the guide groove, and it forms a sliding fit after being embedded in the groove 6. The display screen 4 is fixed to the top of the sliding plate 5 with bolts. The display screen 4 can be adjusted back and forth along the groove 6 with the sliding plate 5 to adapt to the viewing angle of people of different heights. Handles 3 are symmetrically welded to the middle of both sides of the fixed arm 2. The handle 3 is a U-shaped steel pipe covered with anti-slip rubber. The handle 3 is convenient for personnel to hold with both hands, and the force is more even when pushing the device or adjusting the angle of the fixed arm 2. The guide cooperation between the sliding plate 5 and the slide groove 6 ensures that the sliding plate 5 moves only along the length direction. After the position of the display screen 4 is adjusted, there is no tilt, avoiding image distortion when viewing. The handle 3 and the display screen 4 are staggered so that the view of the display screen 4 is not obstructed when holding it. The display screen 4 displays the image captured by the camera 12 in real time. Personnel do not need to get close to the equipment to observe. They can clearly see details such as loose screws and damaged cables. The inspection accuracy is improved compared with the traditional naked eye observation. The sliding plate 5 adjusts the position of the display screen 4 to avoid personnel bending over or standing on tiptoe to view. It is suitable for operators of different heights in the workshop, improving versatility.

[0021] Please refer to Figure 1-5As shown, positioning holes 7 are provided at the bottom of the slide groove 6, the bottom of both sides of the sliding plate 5, the two sides of one end of the fixed arm 2, and the two sides of the moving arm 9.

The fastening rods 8 are common fasteners such as cylindrical steel pins or threaded rods, which can be selected and adjusted by the personnel according to their needs, and their diameter matches the positioning holes 7. The moving arm 9 is locked to the fixed arm 2: after the moving arm 9 is extended to the target length, the positioning holes 7 of the fixed arm 2 and the moving arm 9 are aligned, and the fastening rods 8 are inserted to restrict the sliding of the moving arm 9. The sliding plate 5 is locked to the slide groove 6: after the sliding plate 5 is adjusted to the target position, the positioning holes 7 of the slide groove 6 and the sliding plate 5 are aligned, and the fastening rods 8 are inserted to fix the position of the display screen 4.

[0022] Please refer to Figure 1 , Figure 3 and Figure 4 As shown, locking holes 14 are provided on both sides of the mounting base 1 and on both sides of the other end of the fixing arm 2. Locking holes 14 are provided on both sides of the mounting base 1 and on both sides of the fixing arm 2 near the mounting base 1. After the fixing arm 2 is rotated to the target angle, such as 90° horizontally to check the bottom and 90° vertically to check the top, the locking holes 14 of the mounting base 1 and the fixing arm 2 are aligned, and the fastening rod 8 is inserted to lock the angle of the fixing arm 2, so as to prevent the fixing arm 2 from rotating accidentally during the inspection.

[0023] Please refer to Figure 1-4 As shown, the positioning hole 7 and the locking hole 14 are connected by the fastening rod 8. After locking, the moving arm 9, the sliding plate 5, and the fixed arm 2 have no displacement, and the camera 12 has a stable shooting position, avoiding missed detection due to structural slippage.

[0024] Please refer to Figure 1 and Figure 5As shown, wire holes 17 are provided at the middle position inside the moving arm 9, the middle position inside the inspection block 11, and one end of the slide 6 near the surface of the mounting base 1. The wire hole 17 is provided along the length direction at the middle position inside the moving arm 9, and a vertical wire hole 17 is provided at the middle position inside the inspection block 11, which communicates with the wire hole 17 of the moving arm 9. A horizontal wire hole 17 is provided at one end of the slide 6 near the mounting base 1, which communicates with the interior of the fixed arm 2. The wires are led out from the battery / controller inside the fixed arm 2, pass through the wire holes 17 of the slide 6, the moving arm 9, and the inspection block 11 in sequence, and are connected to the camera 1. 2; The wires of the display screen 4 pass through the wire hole 17 of the slide 6 and are connected to the controller; the diameter of the wire hole 17 is larger than the diameter of the wire, and the path is along the central axis of the structure. When the moving arm 9 extends and retracts, the wires can extend and retract freely in the wire hole 17 without tangling or pulling, avoiding wire wear or breakage; rubber sealing rings are provided at both ends of the wire hole 17 to prevent dust and oil from entering. The fixed arm 2 is filled with fireproof insulating cotton to avoid electrical short circuits and is suitable for environments with a lot of oil and dust in the workshop; the wiring in the wire hole 17 avoids the wires being exposed to the outside, preventing them from being hooked by equipment or contaminated by oil, and at the same time, it avoids the wires from tangling and affecting the extension and retraction of the moving arm 9.

[0025] Please refer to Figure 1 As shown, a controller and a battery are installed inside the fixed arm 2 near the mounting base 1. A rectangular mounting bracket is welded inside the fixed arm 2 near the mounting base 1. The controller, such as a PLC microcontroller, and the battery, such as a lithium battery, are fixed to the mounting bracket with bolts. The two are connected by wires to provide power. The controller is connected to the display screen 4 and the camera 12 by wires to transmit control signals and image data. The built-in battery can provide continuous power without the need for an external power source, making it suitable for areas in the workshop where there are no nearby sockets, such as next to large equipment, thus improving versatility.

[0026] Please refer to Figure 1 and Figure 4As shown, a camera 12 is installed at the top of the inspection block 11. The camera 12, controller, and display screen 4 are all electrically connected to the battery via wires. A threaded hole is opened at the middle of the top of the inspection block 11. The camera 12, such as a high-definition industrial camera 12, is fixed in the threaded hole via a threaded connection. The lens of the camera 12 faces outward and is aligned with the axis of the moving arm 9. The high-definition industrial camera 12 generally has a built-in supplementary light, and the supplementary light surrounds the lens to adapt to the dim environment at the bottom of the equipment. This will not be elaborated further here. The camera 12 is connected to the controller via a wire in the wiring hole 17. The controller processes the image data captured by the camera 12 and transmits it to the display screen 4. Personnel can view the image in real time on the display screen 4. The camera 12 is coaxial with the axis of the moving arm 9, and the shooting direction is consistent with the inspection direction. The brightness of the supplementary light can be adjusted by the controller to adapt to bright / dark environments and ensure clear images. The camera 12 can reach into areas that are difficult for personnel to access, such as the bottom and top of the equipment. The high-definition image displays details, such as loose screws and damaged cable insulation, avoiding blind spots for visual observation.

[0027] Working Principle: In actual use, personnel can adjust the fixed arm 2 horizontally or vertically around the rotating groove 13 on the surface of the mounting base 1 according to the different heights required for visual safety inspection of mechatronic equipment such as machine tools and industrial robots. This allows the fixed arm 2 to be parallel or perpendicular to the ground. When the fixed arm 2 is horizontal, the moving wheels 15 at the bottom of the mounting base 1 and the bottom of the inspection block 11 can contact the ground, facilitating easy movement of the entire inspection device using the moving wheels 15. Support frames 16 are also provided on both sides of the moving wheels 15, providing support for the entire structure and ensuring that the moving wheels 15 do not touch the ground. There is a possibility of tipping over, thus ensuring the stability of the structure. Then, personnel can extend the movable arm 9 to the bottom of the equipment to be inspected. At this time, the camera 12 on the top of the inspection block 11 can obtain information about the bottom of the equipment and transmit it to the display screen 4 via wires. Personnel can then determine whether the bottom of the equipment is intact based on the graphic information on the display screen 4, avoiding damage to the exterior that could expose or damage wiring, thus ensuring the safety of subsequent equipment use. Furthermore, because the entire structure does not require prolonged gripping during low-level inspections, it reduces arm fatigue, thereby extending working time and improving overall inspection efficiency and effectiveness. Similarly, when it is necessary to… When inspecting the top of the equipment, simply raise the fixed arm 2 and align its locking holes 14 with those on the mounting base 1, then lock it with the fastening rod 8 to secure the structure. This prevents the fixed arm 2 from rotating again during raising and causing a hazard. Then, personnel can use the handle 3 to move the device via the casters 15. At this time, the camera 12 can capture images of the top of the equipment and display them on the screen 4, allowing personnel to quickly inspect the equipment from above without climbing. Since the device has casters 15 and a support frame 16 at the bottom for auxiliary movement and support when upright, personnel only act as guides. Compared to traditional structures where the entire weight is placed on the operator's arm, this device significantly reduces labor intensity and facilitates easier use. Furthermore, the fixed arm 2 and the movable arm 9 can extend and retract relative to each other, allowing for inspection of equipment at different heights and depths, thus expanding the overall inspection area and enhancing the structure's practicality. Both the movable arm 9 and the fixed arm 2 have pre-set wire holes 17 for easy wire connection, and the wires are designed according to their maximum extension distance to ensure smooth operation during extension and retraction, preventing them from being too short and affecting normal use. Overall, the device offers advantages such as easy operation, convenient testing, and high practicality.
