[0001] The present invention relates to the technical field of motor visual inspection, and in particular to a motor visual inspection device and method with a visual adjustment mechanism. Background Art

[0002] With the rapid development of modern industrial technology, motors, as core components of various mechanical equipment, have become increasingly important for performance and quality inspection. Traditional motor inspection methods often rely on manual operation and empirical judgment, and their accuracy and efficiency are greatly limited. Therefore, how to achieve efficient and accurate inspection of motors has become an urgent problem to be solved in the current industrial field. In recent years, visual inspection technology has been widely used in the industrial field. This technology simulates the human visual system and uses computers to collect, process and analyze images of the target, thereby realizing automatic inspection of the target state, performance, etc. Compared with traditional inspection methods, visual inspection technology has the advantages of non-contact, high efficiency, and high precision, and is particularly suitable for the inspection of complex components such as motors.

[0003] For example, the patent application with the prior art announcement number CN116773449B discloses a machine vision inspection device for pixel adjustment, including a frame, a conveyor belt is arranged on the frame, partition blocks are evenly arranged on the conveyor belt, side frames are arranged on both sides of the conveyor belt, a translation mechanism is arranged on the side frames, the translation mechanism is connected with an adjustment mechanism, and the adjustment mechanism is connected with a visual detector; the visual detector includes a back plate arranged above the conveyor belt, a detection camera is arranged on the back plate, the back plate is connected with a fixed frame, the back plate and the fixed frame are rotatably installed, a rotating motor is arranged in the fixed frame, and the rotating motor is connected with the back plate; it also includes a centering mechanism, and the centering mechanism is provided with a pitch adjustment component; the present invention realizes driving the visual detector to move to the four sides and the top of the product for visual inspection and shooting through the adjustment mechanism and the translation mechanism, and cooperates with the centering mechanism to push the product to the center of the conveyor belt, thereby improving the efficiency of visual inspection and shooting.

[0004] The above-mentioned prior art can obtain viewing angles of different positions for shooting by adjusting the orientation direction of the visual detector, but in actual use, the sizes of motors of different models may vary greatly, some may be smaller, and some may be larger, which makes the above-mentioned prior art have certain limitations when dealing with motors of different models.

[0015] Preferably, the interior of the rotating column is fixedly connected with a return spring whose elastic end is fixedly connected to a plurality of movable blocks.

[0016] A method for visual inspection of a motor with a visual adjustment mechanism specifically comprises the following steps:

[0017] S1. First, place the motor to be visually inspected on the top of the placement table and directly below the inner disc teeth. The motor can be photographed and inspected by operating multiple visual detectors.

[0018] S2. When multiple visual detectors have finished photographing the motor, they are subsequently moved to obtain a more comprehensive photo. The stepper motor is controlled to rotate quickly so that the drive assembly runs quickly, thereby driving the multiple visual detectors to rotate to another position to photograph the motor a second time.

[0019] S3. Adjust the heights of the multiple visual detectors again so that the multiple visual detectors are located at different height angles for shooting. Turn on the stepper motor and rotate it slowly to make the drive component run slowly, which pulls the rotating disk to rotate and pulls the multiple cranks to tilt, so that the first drive component starts and drives the movable plate to move up, thereby changing the height positions of the multiple visual detectors. Then, the visual detector can be controlled to shoot the motor.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The height of the movable plate can be changed by setting the fixed air cylinder and the slide bar to cooperate with each other, so as to adjust the height of multiple visual detectors. The fixed air cylinder and the slide bar can be driven close to each other by the cooperation of the rotating disk, multiple slide seats and the crank. The top of the fixed air cylinder is ventilated by opening the solenoid valve, and the air is pushed out by the piston to generate air pressure, so as to lock the position between the slide bar and the fixed air cylinder, thereby preventing the position deviation caused by external force or vibration. The stepper motor rotates the rotating column at a slow speed to ensure the stable position of the ball in the inclined slide groove, thereby ensuring the accurate action between the transmission block and the slip ring, so that the height adjustment process of the movable plate is smooth and accurate, and the error caused by too fast or too slow speed is avoided.

[0022] 2. By controlling the speed of the stepper motor to achieve different adjustment effects on multiple visual detectors, when the rotating column rotates rapidly, the ball will be subjected to a strong centrifugal force, causing the ball to impact the movable block away from the rotating column, causing the movable block to collide with the protrusion, thereby driving the connecting rod to rotate. The setting of the ball enables the visual detector to play a conversion function in height adjustment or angle adjustment. This function is easy to operate according to user needs. The stepper motor drives the rotating column to rotate rapidly, and the centrifugal force is used to move the ball in the inclined slide groove, thereby quickly changing the orientation of multiple visual detectors. This design greatly reduces the adjustment time and improves work efficiency. This structure can not only adjust the orientation of the visual detector, but also adjust the height of the visual detector. This dual adjustment function allows the visual detector to adapt to more complex shooting scenes, improving the flexibility and practicality of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Example 1: Please refer to Figure 1 and Figure 3 as well as Figure 4The present invention provides a technical solution: a motor visual inspection device with a visual adjustment mechanism, comprising a top plate 100 and a placement table 101 for placing a power supply motor, both ends of the placement table 101 are respectively fixedly connected with brackets 103 fixedly connected to the top of the top plate 100, a movable plate 200 is arranged directly below the top plate 100, a plurality of visual detectors 104 are evenly fixedly connected to the bottom of the inner disc teeth 300, a first driving component for driving the movable plate 200 to rise and fall is arranged inside the top plate 100, a stepping motor 400 is fixedly connected to the top of the movable plate 200, and a driving rotating disk 20 is arranged at the output end of the stepping motor 400. 6 rotating second drive assembly, the first drive assembly includes a plurality of fixed air cylinders 201 fixedly connected to the inside of the top plate 100, a plurality of sliding rods 202 slidably connected to the bottom of the fixed air cylinders 201 are fixedly connected to the top of the movable plate 200, a crank 205 is hinged on one side of the plurality of fixed air cylinders 201, and a rotating disk 206 for driving the plurality of cranks 205 to tilt is rotatably connected to the top of the movable plate 200. By setting the first drive assembly, the rotating disk 206 can be driven to rotate, thereby driving the cranks 205 to tilt, thereby pulling the movable plate 200 to move in a direction close to the top plate 100 so that the plurality of visual detectors 104 move up or down.

[0038] For further information, see Figure 4 and Figure 5 as well as Fig.12 In order to further improve the stability of the lifting and lowering of the movable plate 200 and its stability after being fixed, the bottoms of the plurality of cranks 205 are rotatably connected to the slide seats 208, the top of the movable plate 200 is evenly provided with a plurality of slide grooves 209 for the slide seats 208 to slide, the interior of the rotating disk 206 is provided with a plurality of arc guide grooves 207 slidably connected to the slide seats 208, the interiors of the plurality of fixed air cylinders 201 are provided with air storage chambers, the tops of the plurality of slide rods 202 are respectively fixedly connected to the pistons 203 adapted to the air storage chambers, and the tops of the plurality of fixed air cylinders 201 are respectively fixedly connected to the electromagnetic valves 204. When the slider 202 rotates, the arc-shaped guide groove 207 moves, thereby changing the position of the slide seat 208, causing the crank 205 to tilt, thereby pulling the slide bar 202 to move in the direction close to the fixed gas cylinder 201, so that the piston 203 moves in the fixed gas cylinder 201, wherein the electromagnetic valve 204 can make the fixed gas cylinder 201 communicate with or close to the outside, so that when the slider 202 moves, the electromagnetic valve 204 opens, and when the slider 202 is stationary, the electromagnetic valve 204 closes, making the fixed gas cylinder 201 airtight, wherein the air pressure between the piston 203 and the fixed gas cylinder 201 assists the crank 205 in supporting the movable plate 200.

[0039] Among them, see Figure 7 and Figure 8 as well as Fig. 9In order to facilitate driving the rotating disk 206 to rotate, the second driving component includes a rotating column 401 fixedly connected to the output end of the stepping motor 400, the top of the rotating column 401 is rotatably connected to a slip ring 412, and the two ends of the top of the slip ring 412 are respectively fixedly connected to connecting handles 413 fixedly connected to the rotating disk 206, and the interior of the rotating column 401 is provided with a co-rotating mechanism that is transmitted by the slip ring 412. By setting up the co-rotating mechanism, the rotating column 401 and the slip ring 412 can cooperate with each other to drive the slip ring 412 to rotate together with them.

[0040] For further information, see Fig.10 and Fig.11 The same-rotation mechanism includes a plurality of polished rods 409 slidably connected to the inside of the rotating column 401, the tops of the plurality of polished rods 409 are respectively fixedly connected with transmission blocks 411, the bottoms of the slip rings 412 are each provided with grooves 414, the insides of the grooves 414 are uniformly and fixedly connected with a plurality of interference blocks 415 that can interfere with the transmission blocks 411, a plurality of inclined grooves 404 are uniformly provided inside the rotating column 401, the insides of the plurality of inclined grooves 404 are each rolled with balls 405 adapted thereto, the bottoms of the plurality of polished rods 409 are each extended to the inside of the inclined grooves 404 and are fixedly connected with inclined blocks 410 that interfere with the balls 405, wherein the balls 405 are provided to support the inclined blocks 410 so that the transmission blocks 411 and the interference blocks 415 are placed at the same height.

[0041] Specifically, when adjusting the height of the movable plate 200, the stepper motor 400 is turned on to drive the rotating column 401 to rotate at a slow speed. At this time, the rotating column 401 obtains a smaller centrifugal force due to the slow rotation speed, and the gravity of the ball 405 and the slope of the inclined slide groove 404 will suppress the centrifugal force, so that the ball 405 is continuously placed under the inclined block 410 without being misplaced. At this time, the rotation of the rotating column 401 will pull the transmission block 411 to rotate with it. At the same time, when the transmission block 411 rotates, it will conflict with the resistance block 415 at the bottom of the slip ring 412, thereby pushing the slip ring 412 to rotate with it. At this time, the rotation of the groove 414 will drive the connecting handles 413 at both ends to rotate with it, and the connecting handles 413 will pull the rotating disk 206 to slide on the top of the movable plate 200. The rotation of the rotating disk 206 will change the axial position of the multiple arc-shaped guide grooves 207, and when the rotating disk 206 rotates clockwise, it will pull the multiple slide seats 208 closer to each other, thereby driving the fixed air cylinder 201 and the slide rod 202 closer to each other. At this time, multiple solenoid valves 204 are opened to allow ventilation to the top of the fixed air cylinder 201, and when the slide rod 202 moves closer to the fixed air cylinder 201, the piston 203 will move up to push the air at its top out of the fixed air cylinder 201. After adjusting the height of the inner disk teeth 300, the stepper motor 400 and the multiple solenoid valves 204 are turned off. At this time, the fixed air cylinder 201 will be in a sealed state. At this time, under the action of the piston 203, the position between the slide rod 202 and the fixed air cylinder 201 will be limited by air pressure, thereby increasing the strength of supporting the movable plate 200.

[0042] In summary, the fixed air cylinder 201 and the slide bar 202 are arranged to cooperate with each other to change the height of the movable plate 200, thereby realizing the adjustment of the height of multiple visual detectors 104, and the fixed air cylinder 201 and the slide bar 202 can be easily driven to approach each other under the cooperation of the rotating disk 206, the multiple slide seats 208 and the crank 205, and the top of the fixed air cylinder 201 is ventilated by opening the solenoid valve 204, and the air is pushed out and air pressure is generated by the piston 203, thereby locking the position between the slide bar 202 and the fixed air cylinder 201. This air pressure locking mechanism greatly enhances the stability of the movable plate 200 after adjustment, and prevents position deviation caused by external force or vibration. The stepper motor rotates the rotating column 401 at a slow speed, ensuring the stable position of the ball 405 in the inclined slide groove 404, thereby ensuring the accurate movement between the transmission block 411 and the slip ring 412. This design makes the height adjustment process of the movable plate 200 smooth and accurate, avoiding errors caused by too fast or too slow speed.

[0043] Embodiment 2: Based on the previous embodiment, in order to facilitate the adjustment of the positions of the multiple visual detectors 104, please refer to Figure 2 and Figure 6The present invention also provides a technical solution: a motor visual inspection device with a visual adjustment mechanism, wherein the bottom of the movable plate 200 is rotatably connected to an idler wheel 301 meshing with the inner disc teeth 300, and the interior of the movable plate 200 and directly below the stepping motor 400 is rotatably connected to a connecting rod 303, and the bottom of the connecting rod 303 extends to the bottom of the movable plate 200 and is fixedly connected to a driving gear 302 meshing with the idler wheel 301.

[0044] For further information, see Fig.11 , different adjustment effects of the visual detector 104 are achieved under different driving speeds of the stepping motor 400, and the connecting rod 303 is provided with a notch placed on the outer surface of the rotating column 401, and a plurality of protrusions 304 are evenly and fixedly connected in the notch of the connecting rod 303, and the outer surface of the rotating column 401 is provided with movable blocks 402 adapted to the plurality of protrusions 304, and both sides of the plurality of movable blocks 402 are constructed with limit grooves 403 slidably connected to the rotating column 401, and the ends of the plurality of movable blocks 402 close to each other are respectively hinged with hinged rods 406, and the ends of the plurality of hinged rods 406 close to each other extend to the inside of the inclined slide groove 404 and are fixedly connected with arc plates 407 that abut against the ball 405.

[0045] Furthermore, in order to facilitate the resetting of the movable block 402 , a resetting spring 408 having an elastic end fixedly connected to the plurality of movable blocks 402 is provided inside the rotating column 401 .

[0046] Specifically, by turning on the stepper motor 400, the drive column 401 is driven to rotate at a fast speed, thereby driving the column 401 to rotate quickly and subjecting it to a strong centrifugal force. At this time, multiple balls 405 will climb and roll in the inclined groove 404 under the action of the centrifugal force, thereby moving away from the position of the inclined block 410. At this time, the inclined block 410 will be affected by gravity and the transmission light rod 409 will slide on the column 401 to drive the transmission block 411 to move downward, thereby moving away from the direction of the slip ring 412. At this time, the slip ring 412 will be placed under the resistance block 415, so that when the column 401 rotates, it will pull the transmission block 411 to slide inside the groove 414, thereby failing to pull the slip ring 412 to slide with it, and the balls 405 of the column 401 will be impacted by the centrifugal force when it rotates at a high speed. Arc plate 407, at this time, the arc plate 407 is subjected to force to move the transmission movable block 402, and then bulges, so that multiple movable blocks 402 bulge out to the outer surface of the rotating column 401, and finally contact with multiple protrusions 304, thereby pulling the connecting rod 303 to rotate, and when the connecting rod 303 rotates, it will drive the driving gear 302 to rotate so that it engages with the idler wheel 301, and then the idler wheel 301 will engage with the inner disk teeth 300 and drive it to rotate, thereby driving multiple visual detectors 104 to change their orientations, and when the adjustment is completed, the rotating column 401 will be in a stationary state, and the ball 405 will fall in the inclined groove 404 under the influence of gravity without the support of centrifugal force to the bottom of the inclined block 410, and at this time it will contact with the inclined block 410 to reset the transmission block 411 and put it back at a height parallel to the contact block 415.

[0047] In summary, by controlling the speed of the stepper motor 400 to achieve different adjustment effects on multiple visual detectors 104, when the rotating column 401 rotates rapidly, the ball 405 will be subjected to a strong centrifugal force, causing the ball 405 to impact the movable block 402 away from the rotating column 401, so that the movable block 402 conflicts with the protrusion 304, thereby driving the connecting rod 303 to rotate. The setting of the ball 405 enables the visual detector 104 to play a conversion function in height adjustment or angle adjustment. This function is convenient for operation according to user needs. The stepper motor 400 drives the rotating column 401 to rotate rapidly, and the centrifugal force is used to move the ball 405 in the inclined slide groove 404, thereby quickly changing the orientation of multiple visual detectors 104. This design greatly reduces the adjustment time and improves work efficiency. This structure can not only adjust the orientation of the visual detector 104, but also adjust the height of the visual detector 104. This dual adjustment function enables the visual detector 104 to adapt to more complex shooting scenes, thereby improving the flexibility and practicality of the equipment.

[0048] Example 3: Please refer to Figures 1 to 12 The present invention provides a technical solution: a method for visual inspection of a motor with a visual adjustment mechanism, specifically comprising the following steps:

[0049] S1. First, place the motor to be visually inspected on the top of the placement table 101 and directly below the inner disc teeth 300. The motor can be photographed and inspected by operating multiple visual detectors 104.

[0050] S2. When the multiple visual detectors 104 have finished photographing the motor, they will then move in a small direction to obtain a more comprehensive photo. By controlling the stepper motor 400, the stepper motor 400 drives the rotating column 401 to rotate at a fast speed, thereby driving the rotating column 401 to rotate quickly. At this time, the multiple balls 405 will climb and roll in the inclined groove 404 under the action of centrifugal force, thereby moving away from the position of the inclined block 410. At this time, the inclined block 410 will be affected by gravity and the transmission light rod 409 will slide on the rotating column 401 to drive the transmission block 411 to move downward, thereby moving away from the direction of the slip ring 412. At this time, the slip ring 412 will be placed below the resistance block 415, so that when the rotating column 401 rotates, it will pull the transmission block 411 inside the groove 414 The sliding of the rotating column 401 makes it impossible to pull the slip ring 412 to slide with it, and the ball 405 of the rotating column 401 will impact the arc plate 407 under the action of centrifugal force when the rotating column 401 rotates at a high speed. At this time, the arc plate 407 is subjected to the force to move the transmission movable block 402, and then bulge out so that multiple movable blocks 402 bulge outward to the outer surface of the rotating column 401, and finally contact with multiple protrusions 304 to pull the connecting rod 303 to rotate. When the connecting rod 303 rotates, it will drive the driving gear 302 to rotate so that it meshes with the idler wheel 301, and then the idler wheel 301 will mesh with the inner disc teeth 300 and drive it to rotate, thereby driving the multiple visual detectors 104 to change their positions, and then the multiple visual detectors 104 can be controlled to take pictures and detect the motor again;

[0051] S3. The heights of the multiple visual detectors 104 can be adjusted again so that the multiple visual detectors 104 can obtain different height angles for shooting. By turning on the stepper motor 400, it drives the rotating column 401 to rotate at a slow speed. The rotating column 401 obtains a smaller centrifugal force due to the slow rotation speed, and the gravity of the ball 405 and the slope of the inclined slide groove 404 will suppress the centrifugal force, so that the ball 405 is continuously placed under the inclined block 410 without being misplaced. At this time, the rotation of the rotating column 401 will pull the transmission block 411 to rotate with it. At the same time, when the transmission block 411 rotates, it will conflict with the resistance block 415 at the bottom of the slip ring 412, thereby pushing the slip ring 412 to rotate with it. At this time, the rotation of the groove 414 will drive the connecting rods at both ends to rotate. The connecting handle 413 rotates with it, and the connecting handle 413 will pull the rotating disk 206 to slide on the top of the movable plate 200. At this time, the rotation of the rotating disk 206 will change the axial position of the multiple arc-shaped guide grooves 207. When the rotating disk 206 rotates clockwise, it will pull the multiple slide seats 208 closer to each other, thereby driving the fixed air cylinder 201 and the slide rod 202 closer to each other. At this time, multiple solenoid valves 204 are opened to allow ventilation at the top of the fixed air cylinder 201. When the slide rod 202 moves close to the fixed air cylinder 201, the piston 203 will move up to push the air at its top out of the fixed air cylinder 201. After adjusting the height of the inner disc teeth 300, the stepping motor 400 and the multiple solenoid valves 204 are closed to fix the height of the movable plate 200.

[0052] S4. The images collected by the multiple visual detectors 104 will then undergo a series of processing, including two main steps: preprocessing and feature extraction. The preprocessing step mainly involves filtering, enhancing, binarizing, and other processing of the images to facilitate subsequent feature extraction. Feature extraction uses image processing technology to extract key features of the motor's operating status from the image, such as shape, texture, color, etc. Based on the extracted features, a model of the motor's quality and operating status will be established, and this model will be used for subsequent motor quality detection and operating status analysis.

[0053] Working principle: When in use, the motor to be visually inspected is placed on the top of the placement table 101 and directly below the inner disc teeth 300, and the motor can be photographed and inspected by controlling multiple visual detectors 104;

[0054] When the orientation of multiple visual detectors 104 needs to be adjusted, the stepper motor 400 is turned on to drive the rotating column 401 to rotate at a fast speed, thereby driving the rotating column 401 to rotate quickly and subjecting it to a strong centrifugal force. At this time, multiple balls 405 will climb and roll in the inclined groove 404 under the action of centrifugal force, thereby moving away from the position of the inclined block 410. At this time, the inclined block 410 will be affected by gravity and the transmission light rod 409 will slide on the rotating column 401 to drive the transmission block 411 to move downward, thereby moving away from the direction of the slip ring 412. At this time, the slip ring 412 will be placed under the resistance block 415, so that when the rotating column 401 rotates, it will pull the transmission block 411 to slide inside the groove 414, thereby failing to pull the slip ring 412 to slide with it, and the balls 405 of the rotating column 401 will be affected by the high-speed rotation. The arc plate 407 is impacted by the centrifugal force. At this time, the arc plate 407 is subjected to the force to move the transmission movable block 402, thereby protruding, so that the multiple movable blocks 402 protrude to the outer surface of the rotating column 401, and finally collide with the multiple protrusions 304, thereby pulling the connecting rod 303 to rotate. When the connecting rod 303 rotates, it will drive the driving gear 302 to rotate so that it meshes with the idler wheel 301. Then, the idler wheel 301 will mesh with the inner disc teeth 300 and drive it to rotate, thereby driving the multiple visual detectors 104 to change their orientations. After the adjustment is completed, the rotating column 401 will be in a stationary state, and the ball 405 will fall to the bottom of the inclined block 410 in the inclined slot 404 under the influence of gravity without the support of centrifugal force. At this time, it will collide with the inclined block 410, so that the transmission block 411 is reset and placed at a height parallel to the conflicting block 415.

[0055] When the height of multiple visual detectors 104 needs to be adjusted, the stepper motor 400 can be turned on to drive the rotating column 401 to rotate at a slow speed. At this time, the rotating column 401 obtains a smaller centrifugal force due to the slow rotation speed, and the gravity of the ball 405 and the slope of the inclined slide groove 404 will suppress the centrifugal force, so that the ball 405 is continuously placed under the inclined block 410 without being misplaced. At this time, the rotation of the rotating column 401 will pull the transmission block 411 to rotate with it. At the same time, when the transmission block 411 rotates, it will conflict with the resistance block 415 at the bottom of the slip ring 412, thereby pushing the slip ring 412 to rotate with it. At this time, the rotation of the groove 414 will drive the connecting handles 413 at both ends to rotate with it, and the connecting handles 413 will pull the rotating disk 206 to slide on the top of the movable plate 200. At this time, the rotation of the rotating disk 206 will change the axial position of the multiple arc-shaped guide grooves 207, and when the rotating disk 206 rotates clockwise, it will pull the multiple slide seats 208 closer to each other, thereby driving the fixed air cylinder 201 and the slide rod 202 closer to each other. At this time, multiple solenoid valves 204 are opened to allow ventilation at the top of the fixed air cylinder 201, and when the slide rod 202 moves close to the fixed air cylinder 201, the piston 203 will move up to push the air at its top out of the fixed air cylinder 201. After adjusting the height of the inner disk teeth 300, the stepper motor 400 and the multiple solenoid valves 204 are turned off. At this time, the fixed air cylinder 201 will be in a sealed state. At this time, under the action of the piston 203, the position between the slide rod 202 and the fixed air cylinder 201 will be limited by air pressure, thereby increasing the strength of supporting the movable plate 200.
