Description

Technical Field

[0001] This application relates to the field of motor testing technology, and in particular to a method for detecting the rotation of a motor's appearance. Background Technology

[0002] Motor appearance inspection refers to the comprehensive inspection and evaluation of a motor's external structure, surface quality, and assembly condition. The purpose is to ensure that the motor's appearance meets design requirements and relevant standards before production, transportation, storage, and use, avoiding performance problems or safety hazards caused by appearance defects. The main inspection contents include surface integrity (such as checking for scratches, dents, cracks, deformation, and other mechanical damage to the casing; confirming the uniformity of the surface coating and the absence of peeling, rust, or oxidation; and observing whether the markings are clear and complete), dimensional and assembly accuracy, and inspection of connections and interfaces.

[0003] In the prior art, a CCD camera is usually used for shooting and inspection, and defects are identified by image processing algorithms. However, since the imaging range of a single CCD camera is limited, the detection range is also limited. Therefore, multiple adjustments are required to complete the inspection, resulting in low overall efficiency. To address this, this application proposes a method for detecting the rotation of a motor's appearance. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this application is to provide a motor appearance rotation detection method to solve the technical problems in the background art.

[0005] The above-mentioned objective of this application is achieved through the following technical solution: a motor appearance rotation detection, including a transport component with a frame already mounted on the frame, a transport tray for placing the motor to be tested is provided on the transport component, an ejection mechanism for ejecting the transport tray is provided at the bottom of the frame, multiple sets of horizontal CCD cameras are provided on the frame, and a vertical pole is fixedly provided at the upper end of the frame, with a vertical CCD camera fixedly provided at the upper end of the vertical pole, and the shooting end of the CCD camera facing downward.

[0006] By adopting the above technical solution, in this application, during inspection, the motor to be inspected is transported to the middle of the frame via a transport component, and then ejected by an ejection mechanism. A 12MP CCD camera at the top of the frame then takes a photograph of the top of the product for inspection. Simultaneously, three 6MP CCD cameras are horizontally mounted on the side, rotating to take pictures and capture images, allowing for a 360° comprehensive inspection of the product's sides, thus enabling simultaneous multi-faceted inspection. According to product inspection requirements and equipment cycle time, a fixed-position camera takes vertical pictures of the product, and the inspection is completed using the captured images.

[0007] Furthermore, the transport assembly includes a pair of transport frames fixedly connected to the frame, a transport belt is fitted on the transport frames, a drive motor for driving the transport belt to rotate is fixedly installed at the bottom of the transport frames, and a transport pallet is placed on the upper end of the transport belt.

[0008] In this application, the drive frame is equipped with drive shafts at both ends, and the output end of the drive motor is fixedly connected to one of the drive shafts. The two ends of the conveyor belt are sleeved on the drive shafts. The drive motor drives the conveyor belt to rotate, thereby driving the transport pallet above. When the transport pallet moves to the ejection mechanism, it is lifted and detected by multiple CCD cameras.

[0009] Furthermore, the ejection mechanism includes an ejection cylinder disposed between the transport frames. The ejection cylinder is fixedly connected to the frame, and a connecting frame is fixedly disposed on the output end of the ejection cylinder. A rotating assembly is disposed within the connecting frame.

[0010] By adopting the above technical solution, when the conveyor belt moves the transport pallet to the top cylinder, the output end is lifted, which in turn lifts the connecting frame and raises the motor, thus facilitating multiple CCD cameras to perform shooting and detection.

[0011] Furthermore, the rotating assembly includes a servo motor fixedly connected to the upper end of the connection, and the output end of the servo motor is provided with a positioning seat for placing the transport pallet.

[0012] By adopting the above technical solution and setting up a servo motor, the transport tray can be rotated left and right during shooting, which makes it more convenient to shoot from multiple angles and improves the inspection efficiency.

[0013] Furthermore, a speed reducer is fixedly connected to the output end of the servo motor, and the output end of the speed reducer is fixedly connected to the positioning seat.

[0014] By adopting the above technical solution, the reducer in this application uses a 1:10 reduction ratio, so that when the servo motor is driven, it will not rotate too fast, resulting in unclear images taken by the CCD camera.

[0015] Furthermore, a positioning pin is fixedly connected to the upper end of the positioning seat, and a positioning hole is opened at the bottom of the transport pallet to be inserted into the positioning pin.

[0016] By adopting the above technical solution, the positioning pin is used to engage with the positioning hole at the bottom of the transport pallet after being ejected by the output end of the ejector cylinder, thus preventing the pallet from detaching when it is rotated.

[0017] Furthermore, a blocking frame is fixedly connected between the frames, a blocking cylinder is fixedly connected to the bottom of the blocking frame, a blocking component is fixedly connected to the middle of the blocking frame, a blocking block is rotatably connected to the blocking component, and the output end of the blocking cylinder abuts against the blocking block.

[0018] By adopting the above technical solution, when the transport pallet moves to the ejector cylinder, the blocking cylinder will push the output end to abut against the blocking block, thereby lifting the blocking block and blocking the movement of the transport pallet. After the transport pallet has completed the inspection, the blocking cylinder will retract, allowing the transport pallet to continue moving with the conveyor belt.

[0019] In summary, this application offers the following beneficial technical advantages: Automated transport components and ejection mechanisms enable rapid positioning and ejection of the motor under inspection, reducing manual operation time and improving inspection efficiency. Multiple horizontally mounted CCD cameras on the side work simultaneously with a top vertical CCD camera, allowing for multi-faceted simultaneous inspection of the motor product, further shortening inspection time. The use of high-resolution CCD cameras for photographic inspection captures subtle defects in the motor product's appearance, improving inspection accuracy. Rotational image capture enables 360° comprehensive inspection of the motor product's sides, avoiding missed inspections due to limited inspection angles. Attached Figure Description

Detailed Implementation

[0025] The present application will be further described in detail below with reference to the accompanying drawings.

[0026] Example, refer to Figure 1 as well as Figure 2A method for rotating and inspecting the appearance of a motor includes a transport assembly mounted on a frame 1. The transport assembly has a transport tray 36 for holding the motor to be inspected. An ejection mechanism is located at the bottom of the frame 1 to eject the transport tray 36. Multiple horizontal CCD cameras 2 are mounted on the frame 1. A vertical pole 21 is fixedly mounted on the upper end of the frame 1, and a vertical CCD camera 22 is fixedly mounted on the upper end of the pole 21, with the imaging end of the CCD camera facing downwards. In this application, during inspection, the motor to be inspected is transported to the middle of the frame 1 via the transport assembly, and then ejected by the ejection mechanism. A 1200W pixel CCD camera at the upper end of the frame 1 then takes a photograph of the top of the product for inspection. Simultaneously, three 600W pixel CCD cameras are horizontally mounted on the side to take rotating photographs, enabling a 360° comprehensive inspection of the product's side surfaces, allowing for simultaneous multi-faceted inspection. According to product inspection requirements and equipment cycle time, the fixed-position camera takes a vertical photograph, and the inspection is completed using the captured product image.

[0027] In this embodiment, refer to Figure 3 as well as Figure 4 The transport assembly includes a pair of transport frames 11 fixedly connected to the frame 1. A transport belt 12 is fitted onto the transport frame 11. A drive motor 13 for driving the transport belt 12 to rotate is fixedly installed at the bottom of the transport frame 11. A transport pallet 36 is placed on the upper end of the transport belt 12. In this application, drive shafts are provided at both ends of the drive frame. The output end of the drive motor 13 is fixedly connected to one of the drive shafts. The two ends of the transport belt 12 are fitted onto the drive shafts. The drive motor 13 drives the transport belt 12 to rotate, thereby driving the transport pallet 36 above. When the transport pallet 36 moves to the ejection mechanism, it is lifted and detected and photographed by multiple CCD cameras.

[0028] In this embodiment, the ejection mechanism includes an ejection cylinder 3 disposed between the transport frames 11. The ejection cylinder 3 is fixedly connected to the frame 1. A connecting frame 31 is fixedly disposed on the output end of the ejection cylinder 3. A rotating component is disposed inside the connecting frame 31. When the transport belt 12 moves the transport tray 36 to the ejection cylinder 3, the output end is lifted, which pushes the connecting frame 31 to raise the motor, thereby facilitating multiple CCD cameras to perform shooting and detection.

[0029] In this embodiment, the rotating component includes a servo motor 32 fixedly connected to the upper end of the connector, and a positioning seat 34 for placing the transport tray 36 is provided on the output end of the servo motor 32. By providing the servo motor 32, the transport tray 36 can be rotated during shooting, thus facilitating shooting from multiple angles.

[0030] In this embodiment, a reducer 33 is fixedly connected to the output end of the servo motor 32, and the output end of the reducer 33 is fixedly connected to the positioning seat 34. The reducer 33 in this application adopts a 1:10 reduction ratio, so that the servo motor 32 will not rotate too fast when driven.

[0031] In this embodiment, a positioning pin 35 is fixedly connected to the upper end of the positioning seat 34, and a positioning hole is opened at the bottom of the transport pallet 36 to engage with the positioning pin 35. The function of the positioning pin 35 is that after being pushed out by the output end of the ejector cylinder 3, it will engage with the positioning hole at the bottom of the transport pallet 36 to complete the docking and prevent the transport pallet 36 from disengaging when it is rotated.

[0032] In this embodiment, a blocking frame 41 is fixedly connected between the frames 1. A blocking cylinder 4 is fixedly connected to the bottom of the blocking frame 41, and a blocking member 42 is fixedly connected to the middle of the blocking frame 41. A blocking block 43 is rotatably connected to the blocking member 42, and the output end of the blocking cylinder 4 abuts against the blocking block 43. When the transport pallet 36 moves to the ejection cylinder 3, the blocking cylinder 4 pushes its output end against the blocking block 43, thereby lifting the blocking block 43 and blocking the movement of the transport pallet 36. After the transport pallet 36 has completed the inspection, the blocking cylinder 4 retracts, allowing the transport pallet 36 to continue moving with the conveyor belt 12.

[0033] Specific implementation process: First, ensure the equipment is placed in a suitable environment with dry, ventilated, flat, and firm ground, free from significant vibration, with an ambient temperature maintained between 15 and 35 degrees Celsius and an air humidity below 70% RH. Connect the power supply and gas lines to provide the necessary power and gas supply to the equipment. Simultaneously, check that all components of the equipment are intact, including the frame 1, transport assembly, ejection mechanism, and CCD camera. Next, place the motor to be tested on the transport tray 36 and ensure it is secure. Then, place the transport tray 36 on the conveyor belt 12 of the transport assembly. Start the drive motor of the transport assembly. Machine 13 drives the conveyor belt 12 to rotate, causing the transport pallet 36 to move towards the center of the frame 1. When the transport pallet 36 moves above the ejection mechanism, the conveyor belt 12 stops rotating. Then, the ejection cylinder 3 is activated, and its output end lifts upward and drives the rotating assembly to rise through the connecting frame 31. The positioning pin 35 on the rotating assembly is inserted into the positioning hole at the bottom of the transport pallet 36 to complete the docking. At the same time, the blocking cylinder 4 pushes the output end against the blocking block 43, lifting the blocking block 43 to prevent the transport pallet 36 from moving and ensuring its stability during the inspection process. After that, a 1200W image sensor on the upper part of the frame 1 is activated. The vertical CCD camera 22 takes pictures of the top of the motor product for inspection. Simultaneously, three horizontally mounted 600W pixel CCD cameras on the side are activated, and the servo motor 32 starts working. Through the reducer 33, the positioning seat 34 and transport tray 36 rotate 360°. During rotation, the three horizontal CCD cameras 2 continuously take pictures, performing a comprehensive inspection of the side of the motor product. The equipment automatically inspects the appearance of the motor product based on the captured images. The inspection results are displayed in real time on the equipment's monitor, and the inspection data is recorded. Simultaneously, the inspection data is transmitted via RF... The ID reader / writer writes the RFID card; after the test is completed, the ejector cylinder 3 descends to place the transport pallet 36 back onto the transport belt 12, and the blocking cylinder 4 retracts to allow the transport pallet 36 to continue moving back to the starting position with the transport belt 12. The CT of the entire test process is controlled within 10.5 seconds. Then, the above steps are repeated to test the next motor to be tested. Finally, the equipment is cleaned and maintained regularly, and the cleanliness and accuracy of optical components such as cameras, lenses, and coaxial light sources are checked. Mechanical components such as the transport belt 12 and rotating mechanism are lubricated and tightened to ensure the stability and durability of the equipment.

[0034] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
