Description

Technical Field

[0001] This invention relates to the field of motor manufacturing equipment technology, specifically to an automated cleaning and photographing device for motor stators. Background Technology

[0002] As a core component of the drive motor in new energy vehicles, the surface quality of the stator directly affects the motor's insulation performance, service life, and operational safety. During the production and processing of the stator, dust, metal burrs, oil stains, and tiny impurities adhering due to electrostatic adsorption are inevitably generated. If these surface contaminants are not thoroughly cleaned and their appearance quality is not fully inspected before leaving the production line, residual foreign objects or defects may lead to short circuits, insulation failures, or even serious quality problems such as motor burnout during subsequent assembly.

[0003] Currently, the industry mostly uses manual operation or semi-automatic equipment to complete the cleaning and inspection of stators before they come off the production line. The common practice is to first use an air gun or cleaning brush to blow or wipe the surface of the stator, and then conduct random inspections of some parts of the stator surface by manual visual inspection or a fixed camera. However, manual cleaning has problems such as uneven cleaning intensity, many blind spots, and low efficiency. Existing semi-automatic equipment can usually only achieve photographic inspection from a single angle or a limited surface, making it difficult to fully cover the six perspectives of the stator, including the outer circumference, end face, inner wall, and bottom. In addition, the stator needs to be transferred and repositioned multiple times between the cleaning and photographing stages, which can easily introduce secondary contamination, and the test results are easily affected by human factors, resulting in poor stability and low automation.

[0004] To address the aforementioned issues, there is an urgent need to develop an automated device that integrates cleaning and six-sided full-coverage photographic inspection functions. This device would enable efficient removal of surface contaminants from new energy motor stators before they come off the production line and accurate identification of appearance defects, thereby improving the consistency and reliability of product quality inspection. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the prior art, the present invention provides an automated cleaning and photographing device for motor stators, which solves the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: An automated cleaning and photographing device for motor stators is provided, comprising: The frame is equipped with two synchronous conveyor belts with gaps between them. Conveyor discs are placed on the two synchronous conveyor belts. A clearance hole is provided in the middle of the conveyor disc. Several arc-shaped locking blocks for limiting the motor stator are provided around the clearance hole. A primary lifting mechanism, comprising a first lifting ring for lifting the conveyor tray and disengaging it from the synchronous conveyor belt; The secondary lifting mechanism includes a second lifting ring for passing through the clearance hole and lifting the motor stator. The middle part of the second lifting ring is provided with an inner support assembly for limiting and fixing the motor stator. Both the second lifting ring and the inner support assembly are mounted on an electric rotary table. Clamping mechanism, used to clamp, lift, and flip the motor stator; The camera assembly includes a first camera for taking pictures of the side of the motor stator and a second camera for taking pictures of the end of the motor stator; Air blowing assembly, used for air blowing to clean the motor stator.

[0007] Furthermore, the primary lifting mechanism also includes a base plate, which is fixed on the frame and located below the first lifting ring. The base plate is connected to the first lifting ring through several first telescopic cylinders, and several first guide posts are provided at the bottom of the first lifting ring. Several first linear bearings that slide with the first guide posts are provided on the base plate. Several positioning pins and several rubber pads for contacting the bottom of the conveyor plate are provided on the first lifting ring, and several positioning holes that cooperate with the positioning pins are provided at the bottom of the conveyor plate.

[0008] Furthermore, the secondary lifting mechanism also includes a lifting plate, an electric rotary table is mounted on the lifting plate, a number of second linear bearings are mounted on the lifting plate, a number of second guide columns that slide in cooperation with the second linear bearings are mounted on the bottom of the base plate, and the lifting plate and the base plate are connected by a number of second telescopic cylinders.

[0009] Furthermore, the inner support assembly includes several arc-shaped inner support blocks for abutting against the inner sidewall of the motor stator. The arc-shaped inner support blocks are evenly arranged in the circumferential direction of the second lifting ring and are driven by the cylinder assembly to synchronously expand radially outward or contract radially inward.

[0010] Furthermore, the clamping mechanism includes a lifting vertical plate that is slidably disposed on one side of the frame, and the lifting vertical plate is connected to the frame via a third telescopic cylinder. A first electric turntable is provided on one side of the lifting vertical plate, and a pneumatic gripper for clamping the outer wall of the motor stator is provided on the first electric turntable.

[0011] Furthermore, the camera assembly also includes a horizontal sliding block driven by a fourth telescopic cylinder, on which a vertical linear module is provided. The first camera is fixed on the slider of the linear module and located on one side of the motor stator, and the second camera is fixed on the frame located above the motor stator.

[0012] Furthermore, the air blowing assembly includes a second electric turntable fixed on the frame. The second electric turntable is provided with a horizontal plate, and both ends of the horizontal plate are provided with vertically downward air blowing heads. The two air blowing heads are located above the motor stator and are connected to an external compressed air supply device through a hose. The second electric turntable is configured to rotate 180 degrees in the forward direction and then rotate 180 degrees in the reverse direction, and repeat this process.

[0013] Furthermore, both ends of the horizontal plate are provided with strip-shaped mounting holes, and both sides of the strip-shaped mounting holes are provided with strip-shaped bolt holes. The air blower head passes through the strip-shaped mounting holes and is fastened to the strip-shaped bolt holes with bolts.

[0014] Furthermore, the inner arc surfaces of several arc-shaped blocks are all clearance-fitted with the outer side wall of the motor stator, and the inner arc surfaces of the arc-shaped blocks are provided with arc-shaped support platforms for supporting the bottom of the motor stator.

[0015] Furthermore, the two synchronous conveyor belts are equipped with lifting and blocking cylinders for stopping the conveyor trays, the bottom of the frame is equipped with proximity sensors for detecting the passage of the conveyor trays, and the sides of the frame are equipped with laser beam sensors for detecting whether a motor stator is placed on the conveyor tray.

[0016] The beneficial effects of this invention are as follows: 1. This solution uses a primary lifting mechanism to lift the conveyor tray, detaching it from the synchronous conveyor belt. A secondary lifting mechanism lifts the motor stator on the conveyor tray, and an internal support assembly limits and fixes the motor stator. An electric rotary table then rotates the motor stator, allowing the first camera to capture a comprehensive view of its outer surface. Next, a clamping mechanism holds the motor stator and lifts it upwards, bringing it closer to the second camera and air-blowing assembly, facilitating the second camera's view of the stator's end. Simultaneously, the air-blowing assembly cleans the motor stator. Afterwards, the clamping mechanism flips the motor stator, repeating the end-viewing and air-blowing cleaning process. Finally, the clamping mechanism returns the motor stator to the conveyor tray, resetting the primary and secondary lifting mechanisms. This achieves fully automated cleaning and photographing of the motor stator, ensuring comprehensive cleaning and no blind spots in the photographing.

[0017] 2. This solution uses a proximity sensor to detect the passage of the conveyor tray, which causes the lifting and blocking cylinder to rise in advance and stop the conveyor tray, so that the conveyor tray can be accurately lifted later. A laser beam sensor can detect whether a motor stator is placed on the conveyor tray, so as to determine whether the subsequent cleaning and photography steps should be performed.

[0018] 3. The internal support assembly of this solution expands radially outward synchronously through several arc-shaped internal support blocks and abuts against the inner side wall of the motor stator, thereby achieving the limiting and fixing of the motor stator. This fixing method ensures that the outer side wall of the motor stator is completely unobstructed, facilitating full-view photography of the outer side of the motor stator. At the same time, the pneumatic gripper holds the outer side wall of the motor stator, ensuring that the ends and inner side wall of the motor stator are completely unobstructed during photography, thus automatically achieving full-view photography of the motor stator.

[0019] 4. The air blowing assembly of this solution can perform circumferential air blowing cleaning of the motor stator through two air blowing heads that rotate 180 degrees in both directions, and effectively avoid the hose connected to the air blowing head from getting tangled due to excessive rotation; at the same time, the spacing between the two air blowing heads can be adjusted by the cooperation of the strip mounting holes, strip bolt holes and bolts, so as to adapt to motor stators with different radial dimensions.

[0020] 5. The first camera in this solution can be adjusted in both horizontal and vertical directions via the fourth telescopic cylinder and the linear module, allowing the first camera to perform both overall side views and detailed close-up views of defect locations, making it highly practical.

[0033] Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0034] like Figures 1 to 7 As shown, the automatic cleaning and photographing equipment for motor stators in this solution includes a frame 11, on which two synchronous conveyor belts 12 with gaps are threaded. The frame 11 is equipped with a primary lifting mechanism, a secondary lifting mechanism, a clamping mechanism, a photographing component, and an air blowing component.

[0035] Two synchronous conveyor belts 12 are equipped with conveyor discs 13. A clearance hole is provided in the middle of the conveyor disc 13, and three arc-shaped blocks 14 are provided around the clearance hole. The inner arc surface of the arc-shaped blocks 14 is in clearance fit with the outer wall of the motor stator 9, and an arc-shaped mounting platform 141 for supporting the bottom of the motor stator 9 is provided on the inner arc surface of the arc-shaped blocks 14 to achieve the limiting placement of the motor stator 9.

[0036] As an optional implementation, the primary lifting mechanism includes a base plate 22 and a first lifting ring 21 for lifting the conveyor plate 13 and disengaging it from the synchronous conveyor belt 12. The base plate 22 is fixed on the frame 11 and located below the first lifting ring 21. The base plate 22 and the first lifting ring 21 are connected by several first telescopic cylinders 23. Several first guide posts 24 are provided at the bottom of the first lifting ring 21. Several first linear bearings 25 that slide with the first guide posts 24 are provided on the base plate 22. Several positioning pins 26 and several rubber pads 27 for contacting the bottom of the conveyor plate 13 are provided on the first lifting ring 21. Several positioning holes that cooperate with the positioning pins 26 are provided at the bottom of the conveyor plate 13. During the process of the first lifting ring 21 lifting the conveyor plate 13 upward, the positioning pins 26 and the positioning holes can be used to achieve the pre-positioning of the conveyor plate 13 to ensure the stability of the lifting process.

[0037] As an optional implementation, the secondary lifting mechanism includes a lifting plate 33 and a second lifting ring 31 for passing through the clearance hole and lifting the motor stator 9. The middle part of the second lifting ring 31 is provided with an inner support assembly for limiting and fixing the motor stator 9. Both the second lifting ring 31 and the inner support assembly are mounted on an electric rotary table 32, which is mounted on the lifting plate 33. The lifting plate 33 is provided with a plurality of second linear bearings 34. The bottom of the base plate 22 is provided with a plurality of second guide posts 35 that slide in cooperation with the second linear bearings 34. The lifting plate 33 and the base plate 22 are connected by a plurality of second telescopic cylinders 36.

[0038] As an optional implementation, the inner support assembly includes three arc-shaped inner support blocks 37 for abutting against the inner wall of the motor stator 9. The three arc-shaped inner support blocks 37 are evenly arranged in the circumferential direction of the second lifting ring 31 and are driven by the cylinder assembly to synchronously expand radially outward or retract radially. When the three arc-shaped inner support blocks 37 synchronously expand radially outward and abut against the inner wall of the motor stator 9, the motor stator 9 is limited and fixed on the second lifting ring 31. This fixing method makes the outer wall of the motor stator 9 completely unobstructed, so as to facilitate full-viewing of the outer side of the motor stator 9.

[0039] As an optional implementation, the clamping mechanism of this solution is used to clamp, lift, and flip the motor stator 9. It includes a lifting vertical plate 51 slidably disposed on one side of the frame 11, and the lifting vertical plate 51 is connected to the frame 11 through a third telescopic cylinder 52. A first electric turntable 53 is provided on one side of the lifting vertical plate 51, and a pneumatic gripper 54 for clamping the outer wall of the motor stator 9 is provided on the first electric turntable 53. When the pneumatic gripper 54 clamps the outer wall of the motor stator 9, the end and inner wall of the motor stator 9 are completely unobstructed, so as to facilitate full-viewing of the end and inner wall of the motor stator 9.

[0040] As an optional implementation, the camera assembly includes a first camera 41 for taking pictures of the side of the motor stator 9 and a second camera 42 for taking pictures of the end of the motor stator 9. The first camera 41 is located on one side of the motor stator 9, and the second camera 42 is fixed on the frame 11 located above the motor stator 9.

[0041] The working principle of this solution will be explained in detail below: This solution uses a primary lifting mechanism to lift the conveyor tray 13, detaching it from the synchronous conveyor belt 12. A secondary lifting mechanism lifts the motor stator 9 on the conveyor tray 13, and an internal support assembly limits and fixes the motor stator 9. The motor stator 9 can then be rotated by the electric rotary table 32, allowing the first camera 41 to capture a full view of the outer side of the motor stator 9. Afterward, a clamping mechanism holds the motor stator 9 and lifts it upward, bringing it closer to the second camera 42 and the air blowing assembly, allowing the second camera 42 to capture a view of the end of the motor stator 9. Simultaneously, the air blowing assembly cleans the motor stator 9. Afterward, the clamping mechanism flips the motor stator 9, repeating the image capture and air blowing cleanup of the end of the motor stator 9. Finally, the clamping mechanism returns the motor stator 9 to the conveyor tray 13, and the primary and secondary lifting mechanisms are reset. This achieves fully automated cleaning and photography of the motor stator 9, ensuring comprehensive cleaning and no blind spots in the photography.

[0042] As an optional implementation, a horizontal sliding block 43 driven by a fourth telescopic cylinder 45 is provided on one side of the frame 11. A vertical straight module 44 is provided on the horizontal sliding block 43. The first camera 41 is fixed on the slider of the straight module 44, so that the position of the first camera 41 can be adjusted in the horizontal and vertical directions through the fourth telescopic cylinder 45 and the straight module 44. This allows the first camera 41 to take overall side shots as well as close-up detailed shots of defect locations, thereby enhancing its practicality.

[0043] As an optional implementation, the air-blowing assembly is used for air-blowing cleaning of the motor stator 9. It includes a second electric turntable 61 fixed on the frame 11. A horizontal plate 62 is provided on the second electric turntable 61. Vertically downward air-blowing heads 63 are provided at both ends of the horizontal plate 62. The two air-blowing heads 63 are located above the motor stator 9 and are connected to an external compressed air supply device through hoses. The second electric turntable 61 is configured to rotate 180 degrees in the forward direction and then rotate 180 degrees in the reverse direction, and repeat this process. This configuration allows for comprehensive air-blowing cleaning of the motor stator 9 in the circumferential direction and effectively prevents the hoses connected to the air-blowing heads 63 from becoming tangled due to excessive rotation.

[0044] As an optional implementation, both ends of the horizontal plate 62 are provided with strip-shaped mounting holes 64, and both sides of the strip-shaped mounting holes 64 are provided with strip-shaped bolt holes 65. The air blower 63 passes through the strip-shaped mounting holes 64 and is fastened to the strip-shaped bolt holes 65 with bolts. Through the cooperation of the strip-shaped mounting holes 64, the strip-shaped bolt holes 65 and the bolts, the distance between the two air blowers 63 can be adjusted to adapt to motor stators 9 with different radial dimensions.

[0045] Specifically, to achieve automatic cleaning and photography, this solution includes two synchronous conveyor belts 12 equipped with lifting and blocking cylinders 71, a proximity sensor at the bottom of the frame 11, and laser beam sensors on both sides of the frame 11. The proximity sensor can detect the passage of the conveyor plate 13, thereby causing the lifting and blocking cylinders 71 to rise in advance and stop the conveyor plate 13, so that the conveyor plate 13 can be accurately lifted afterward. The laser beam sensor can detect whether the motor stator 9 is placed on the conveyor plate 13, so as to determine whether the subsequent cleaning and photography steps should be executed.

[0046] The top and outer sides of the frame 11 can be covered by baffles 81, and lifting gates 82 can be installed at the inlet and outlet ends of the frame 11 to achieve the effect of closed shooting and reducing air dust.

[0047] Although the specific embodiments of the invention have been described in detail with reference to the accompanying drawings, this should not be construed as limiting the scope of protection of this patent; various modifications and variations that can be made by a person skilled in the art without inventive effort within the scope described in the claims are still within the scope of protection of this patent.
