Description

Technical Field

[0001] This invention relates to the field of industrial visual inspection, and more particularly to an intelligent quality inspection device for tinning of hollow cup motor coils. Background Technology

[0002] The coreless motor coil is the core conductive and electromagnetic conversion component of the coreless motor. After the coreless motor coil is immersed in tin, it needs to be tested. The core reason is that the quality of the tinning directly determines the electrical performance, structural reliability and service life of the motor. During the production process, due to factors such as process fluctuations and material characteristics, latent or obvious defects are easily generated. If defective products are not detected and removed in time, it will not only lead to motor failure, but may also cause safety risks or significantly increase the subsequent repair costs.

[0003] In related technologies, after the coreless motor coil is tinned, an industrial camera is typically used to photograph the tinned area, and an image processing system is used for visual inspection. However, existing quality inspection devices are not convenient for adjusting the lighting position according to the working position of the industrial camera, leading to missed detection of three-dimensional defects. At the same time, glare and reflection interference can create blind spots in the inspection, resulting in low accuracy of the inspection data.

[0004] Therefore, it is necessary to provide an intelligent quality inspection device for tinning coils of hollow cup motors to solve the above-mentioned technical problems. Summary of the Invention

[0012] Preferably, a dust removal mechanism is fixedly provided on the top of the inner wall of the mounting frame.

[0015] Compared with related technologies, the intelligent quality inspection device for tinning hollow cup motor coils provided by the present invention has the following advantages: When the industrial camera moves down from a high-position shooting state to adjust its shooting position, the mounting bracket simultaneously moves the pressure bracket down. The downward movement of the pressure bracket compresses the slider, thereby switching the LED strip light from high-position vertical light to medium-low angle light and then to extremely low angle light in sequence. This facilitates the industrial camera's shooting operation, making it easier and more accurate to take pictures and effectively improving the accuracy of the detection data. When the industrial camera is at a high position, the LED strip light uses high-position vertical light, which has a wide light coverage and high uniformity, and can clearly present the overall outline of the tin-immersed area, avoiding local shadows. The industrial camera can obtain an image that is uniform overall and without severe shadows, which is convenient for the algorithm to quickly locate and make preliminary judgments. When the industrial camera is lowered to the middle position, the light from the low-to-medium angle is closer to the tin-plated surface. The contrast between the tin-plated layer and the coil substrate can be enhanced by side lighting, allowing the industrial camera to capture grayscale changes more clearly and reducing the problem of blurry details under vertical light. The low-to-medium angle light produces moderate shadows, which enhances the contrast of the two-dimensional contour and enables the edge extraction algorithm to run accurately. When the industrial camera is lowered to a low position, the extremely low-angle light is almost parallel to the tin-immersed surface. The light has weak penetration but strong shadow projection ability. Small defects will form obvious local shadows. The industrial camera can accurately capture these shadow signals, preventing small defects from being covered by vertical light or medium-low angle light, and greatly improving the defect detection rate.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0020] This invention provides an intelligent quality inspection device for tinning coils in hollow cup motors.

[0021] First embodiment: Please see Figures 1 to 8 A smart quality inspection device for tinning coils of hollow cup motors includes a mounting frame 1, an inspection mechanism 2, an inspection auxiliary mechanism 3, and a moving mechanism 4. The detection mechanism 2 includes two slide rails 21 and a sliding seat 22. The two slide rails 21 are fixed on opposite sides of the inner wall of the mounting frame 1. The sliding seat 22 is slidably connected to the slide rails 21. A mounting bracket 23 is fixed on the front side of the sliding seat 22. An industrial camera 24 is provided on the front side of the mounting bracket 23. A distance sensor 25 is provided on the top of the sliding seat 22 and the top of the inner wall of the mounting frame 1. Please combine Figure 4 Industrial camera 24 is used to photograph the tin-immersed part of the hollow cup motor coil. After the image is taken, it is sent to the industrial control computer. The industrial control computer performs real-time image processing and analysis. When the quality inspection fails, the sound and light alarm 13 is triggered to remind the user. Distance sensor 25 is used to work with industrial camera 24. When distance sensor 25 detects that industrial camera 24 coincides with the preset trigger distance value, it transmits the signal to industrial control computer. Industrial control computer controls industrial camera 24 to work. The mounting bracket 1 has a mounting seat 5 fixedly mounted on its inner wall. The detection auxiliary mechanism 3 includes a slider 31 slidably connected to the inner side of the mounting seat 5. A rotating rod 32 is rotatably connected to the inner side of the slider 31. An LED strip light 33 is fixedly mounted at the front end of the rotating rod 32. A rotating gear 34 is fixedly mounted at the rear end of the rotating rod 32. Two rotating toothed plates 35 are fixedly mounted from top to bottom on the rear side of the mounting seat 5. A spring 36 is provided on the inner side of the mounting seat 5 and at the bottom of the slider 31. Two pressing brackets 37 are fixedly mounted on the back of the mounting bracket 23 by bolts. Please combine Figure 6When the mounting bracket 23 moves the industrial camera 24 downward to adjust the shooting position, the downward movement of the mounting bracket 23 also moves the two pressing brackets 37 downward. When the two pressing brackets 37 move downward and contact the two sliders 31 respectively, they will press the two sliders 31 downward. The downward movement of the two sliders 31 drives the LED strip light 33 and the rotating gear 34 downward through the rotating rod 32. When the rotating gear 34 contacts the rotating tooth plate 35 at the top, it will cause the two LED strip lights 33 to rotate inward at the same time. As a result, when the industrial camera 24 is in the middle shooting position, the height of the LED strip light 33 will be lowered and closer to the tin-immersed part of the hollow cup motor coil. The industrial camera 24 is assisted by medium and low angle light for shooting. Please combine Figure 7 When the mounting bracket 23 continues to move the industrial camera 24 downwards and adjusts the industrial camera 24 to a low position for shooting, the pressing bracket 37 will simultaneously press the slider 31 downwards. The downward movement of the slider 31 will cause the LED strip light 33 and the rotating gear 34 to continue to move downwards. When the rotating gear 34 contacts the rotating tooth plate 35 at the bottom, it will cause the two LED strip lights 33 to continue to rotate inwards, thereby using extremely low-angle light to assist the industrial camera 24 in shooting. Furthermore, when the industrial camera 24 is shooting from a high position, the downward support 37 and the slider 31 will not come into contact. At this time, the LED strip light 33 uses high-position vertical light to assist the industrial camera 24 in shooting. Furthermore, when the mounting bracket 23 moves the industrial camera 24 and the pressure bracket 37 upward, the expansion force of the spring 36 will cause the slider 31 to slide upward on the inner side of the mounting base 5, thereby resetting the LED strip light 33. After resetting, the LED strip light is in a high-position vertical light state. The moving mechanism 4 is vertically arranged inside the mounting frame 1 and is used to adjust the working height of the industrial camera 24.

[0022] The detection auxiliary mechanism 3 is arranged in two sets in a left-right mirror image. The inner side of the mounting base 5 is provided with a moving groove that cooperates with the rotating rod 32 to provide the rotating rod 32 for up-down movement.

[0023] The inner side of the pressure bracket 37 is provided with a through groove, and the height of the pressure bracket 37 can be adjusted by the cooperation of bolts with the through groove.

[0024] In this embodiment, when the industrial camera 24 moves downward from the high-position shooting state to adjust the shooting position, the mounting bracket 23 simultaneously drives the pressing bracket 37 to move downward. The pressing bracket 37 moves downward and squeezes the slider 31 to move downward, thereby switching the LED strip light 33 from high-position vertical light to medium-low angle light and extremely low angle light in sequence. This works in conjunction with the shooting operation of the industrial camera 24, making it easier for the industrial camera 24 to shoot more accurately and effectively improving the accuracy of the detection data. When the industrial camera 24 is at a high position, the LED strip light 33 adopts high-position vertical light, which has a wide light coverage and high uniformity, and can clearly present the overall outline of the tin-immersed part, avoiding local shadows. The industrial camera 24 can obtain an image that is uniform overall and without severe shadows, which is convenient for the algorithm to quickly locate and make preliminary judgments. When the industrial camera 24 is lowered to the middle position, the light from the low-to-medium angle is closer to the tin-plated surface. The contrast between the tin-plated layer and the coil substrate can be enhanced by side lighting, allowing the industrial camera 24 to capture grayscale changes more clearly and reducing the problem of blurred details under vertical light. The low-to-medium angle light produces moderate shadows, which enhances the contrast of the two-dimensional contour and enables the edge extraction algorithm to run accurately. When the industrial camera 24 is lowered to a low position, the extremely low-angle light is almost parallel to the tin-immersed surface. The light has weak penetration but strong shadow projection ability. Small defects will form obvious local shadows. The industrial camera 24 can accurately capture these shadow signals, avoid small defects being covered by vertical light or medium-low angle light, and greatly improve the defect detection rate.

[0025] Second embodiment: Please see Figures 9 to 11 The moving mechanism 4 includes a bidirectional threaded screw 41 that is vertically rotatably connected inside the mounting frame 1. A movable screw block 42 is threadedly connected to the surface of the bidirectional threaded screw 41. The front of the movable screw block 42 is fixedly connected to the sliding seat 22. A drive motor 43 for driving the bidirectional threaded screw 41 to rotate is provided on the top of the mounting frame 1. Please combine Figure 9 and Figure 10 Start the drive motor 43. The drive motor 43 rotates and drives the bidirectional threaded screw 41 to rotate. The bidirectional threaded screw 41 rotates and drives the moving screw block 42 to move downward. The moving screw block 42 moves downward and drives the sliding seat 22 to move downward. The sliding seat 22 moves downward and drives the mounting bracket 23 and the industrial camera 24 to move downward, thereby adjusting the working height of the industrial camera 24 downward. By reversing the drive motor 43, the industrial camera 24 can be adjusted upward. A cleaning and protection mechanism 6 is fixedly provided on the right side of the inner wall of the mounting frame 1. The cleaning and protection mechanism 6 includes a guide plate 61 fixedly provided on the right side of the inner wall of the mounting frame 1. An electric telescopic rod 62 is fixedly provided on the front side of the guide plate 61. A flipping toothed plate 63 is fixedly provided at the output end of the electric telescopic rod 62. The flipping toothed plate 63 is slidably connected to the guide plate 61. A rotating shaft 64 is rotatably connected to the inner side of the mounting bracket 23. A flipping gear 65 is fixedly provided on the surface of the rotating shaft 64. The front end of the rotating shaft 64 is fixedly connected to the industrial camera 24. A protective frame 66 is fixedly provided on the left side of the front of the mounting frame 1. An adjusting screw 67 is threadedly connected to the inner side of the protective frame 66. A cleaning plate 68 is rotatably connected to the right end of the adjusting screw 67. Please combine Figure 11 When the moving mechanism 4 drives the industrial camera 24 to move upward, the flip gear 65 contacts the flip gear plate 63, and the flip gear 65 drives the industrial camera 24 to rotate 90 degrees clockwise through the rotating shaft 64. Through the continuous work of the moving mechanism 4, the industrial camera 24 continues to move upward. During the upward movement of the industrial camera 24, the cleaning plate 68 is used to clean the lens, and the protective frame 66 is used to protect the lens. Preferably, there is a large frictional force between the rotating shaft 64 and the mounting bracket 23 to prevent the industrial camera 24 from automatically shifting.

[0026] A lint-free cloth is provided on the right side of the cleaning plate 68. By rotating the adjusting screw 67, the cleaning plate 68 can be moved to the left to cancel the cleaning state.

[0027] In this embodiment, the tin-immersion test of the hollow cup motor coil is carried out in an industrial environment. There may be contaminants such as tin dust, rosin fumes or dust in the air, which can cause blurry images or grayscale distortion if they adhere to the surface of the camera lens. The moving mechanism 4 drives the industrial camera 24 to move upward. With the cooperation of the flip gear 65, the rotating shaft 64 and the flip tooth plate 63, the industrial camera 24 rotates 90 degrees clockwise. The cleaning plate 68 is used to clean the lens, which can eliminate the interference of lens contamination on imaging. The protective frame 66 is used to protect the lens, physically isolate it from external damage, and extend the lens life.

[0028] Third embodiment: Please see Figure 1 , Figure 12 and Figure 13 A dust removal mechanism 7 is fixedly provided on the top of the inner wall of the mounting frame 1. The dust removal mechanism 7 includes an air cylinder 71 fixedly provided on the top of the inner wall of the mounting frame 1. A piston 72 and a push rod 73 are slidably connected to the inner side of the air cylinder 71. The top end of the push rod 73 is fixedly connected to the bottom of the piston 72. A return spring 74 is sleeved on the surface of the push rod 73. A trigger plate 75 is rotatably connected to the bottom end of the push rod 73. Please combine Figure 13 The electric telescopic rod 62 retracts, causing the flipping tooth plate 63 to move to the right, so that the flipping gear 65 and the flipping tooth plate 63 are not on the same vertical line. When the moving mechanism 4 drives the sliding seat 22 and the industrial camera 24 to move upward, when the top of the sliding seat 22 contacts the trigger plate 75, the trigger plate 75 will cause the push rod 73 to drive the piston 72 to slide upward on the inside of the air cylinder 71, thereby delivering the gas through the hose to the air nozzle 9, and using the air nozzle 9 to remove dust from the tin-immersed part of the hollow cup motor coil. Furthermore, when the moving mechanism 4 drives the sliding seat 22 and the industrial camera 24 to reset downwards, the expansion force of the reset spring 74 drives the trigger plate 75 and the push rod 73 to reset downwards, causing the piston 72 to slide downwards on the inner wall of the air cylinder 71, thereby completing the air extraction work. When the trigger plate 75 is rotated 180 degrees and the sliding seat 22 moves upwards, the push rod 73 will not be triggered to work. Preferably, the surface of the air cylinder 71 is connected to a hose and an air extraction pipe, and both the surface of the hose and the air extraction pipe are provided with a one-way valve. The mounting base 5 has two adjusting seats 8 slidably connected to its inner side. Each of the two adjusting seats 8 is provided with an air blowing nozzle 9, which is connected to the air cylinder 71 through a hose.

[0029] A protective plate 10 is fixed to the front side of the mounting bracket 1. A movable groove for cooperating with the rotating rod 32 and the rotating shaft 64 is opened on the inner side of the protective plate 10. A base plate 11 is fixed to the bottom of the mounting bracket 1. A mounting hole 12 is opened on the inner side of the base plate 11. An audible and visual alarm 13 is provided on the right side of the top of the mounting bracket 1.

[0030] In this embodiment, during the tin-immersion inspection of the hollow cup motor coil, if impurities such as residual tin dross, dust, and rosin fragments remain in the tin-immersion area, they are easily misjudged as tin-immersion defects by the industrial camera 24. When the moving mechanism 4 drives the sliding seat 22 and the industrial camera 24 to move upward, and the top of the sliding seat 22 contacts the trigger plate 75 and continues to move upward, the gas in the air cylinder 71 is blown out through the air nozzle 9 by the push rod 73 and the piston 72, thereby cleaning the tin-immersion area and avoiding misjudgment during the inspection process. In addition, the smooth movement of the sliding seat 22 can form a smooth airflow, which can avoid disturbing the workpiece and causing displacement.

[0031] Please refer to the reference again. Figures 1 to 13 The working principle of the intelligent quality inspection device for tinning hollow cup motor coils provided by this invention is as follows: Step S1: When the hollow cup motor coil after tinning moves to the bottom of the industrial camera 24, the industrial control computer sends a command to control the electric telescopic rod 62 to retract, driving the flipping tooth plate 63 to move to the right, so that the flipping gear 65 and the flipping tooth plate 63 are not on the same vertical line. Start the drive motor 43. The drive motor 43 rotates and drives the bidirectional threaded screw 41 to rotate. The bidirectional threaded screw 41 drives the sliding seat 22 and the industrial camera 24 to move upward through the moving screw block 42. When the top of the sliding seat 22 contacts the trigger plate 75, the trigger plate 75 will cause the push rod 73 to drive the piston 72 to slide upward inside the air cylinder 71, thereby delivering the gas through the hose to the air nozzle 9. The air nozzle 9 is used to remove dust from the tin-immersed part of the hollow cup motor coil. Step S2: After dust removal, control the drive motor 43 to reverse. The drive motor 43 rotates, causing the bidirectional threaded screw 41 to rotate. The bidirectional threaded screw 41 rotates, causing the moving screw block 42 to move downward. The moving screw block 42 moves downward, causing the sliding seat 22 to move downward. The sliding seat 22 moves downward, causing the mounting bracket 23 and the industrial camera 24 to move downward, thereby adjusting the working height of the industrial camera 24 downward. The height position of the industrial camera 24 is monitored by the distance sensor 25. When the industrial camera 24 is shooting at a high position, the pressure bracket 37 and the slider 31 will not contact each other. At this time, the LED strip light 33 uses high-position vertical light to assist the industrial camera 24 in shooting. In step S3, combined with step S2, when the mounting bracket 23 continues to move downwards, driving the pressing bracket 37 to move, and the industrial camera 24 is adjusted to the center position for shooting, the two pressing brackets 37 move downwards and contact the two sliders 31 respectively, pressing the two sliders 31 downwards. The downward movement of the two sliders 31 drives the LED strip lights 33 and the rotating gear 34 downwards via the rotating rod 32. When the rotating gear 34 contacts the rotating toothed plate 35 at the top, it causes the two LED strip lights 33 to rotate inwards simultaneously. Consequently, when the industrial camera 24 is in the center position for shooting, the height of the LED strip lights 33 will decrease, approaching the tin-plated part of the hollow cup motor coil. A low-to-medium angle light is used to assist the industrial camera 24 in shooting. As the mounting bracket 23 continues to move the industrial camera 24 downwards and adjusts the industrial camera 24 to a low position for shooting, the pressing bracket 37 will simultaneously press the slider 31 downwards. The downward movement of the slider 31 will cause the LED strip light 33 and the rotating gear 34 to continue to move downwards. When the rotating gear 34 contacts the rotating toothed plate 35 at the bottom, it will cause the two LED strip lights 33 to continue to rotate inwards, thereby using extremely low-angle light to assist the industrial camera 24 in shooting. Step S4: When it is necessary to clean or protect the lens, start the drive motor 43 to move the industrial camera 24 upward. After the flip gear 65 contacts the flip tooth plate 63, the flip gear 65 drives the industrial camera 24 to rotate 90 degrees clockwise through the rotating shaft 64. Through the continuous work of the moving mechanism 4, the industrial camera 24 continues to move upward. During the upward movement of the industrial camera 24, the cleaning plate 68 is used to clean the lens, and the protective frame 66 is used to protect the lens.
