Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, and more specifically, to a rotary capacitor appearance inspection device. Background Technology

[0002] During the production and handling of capacitors, defects can easily occur in their appearance, such as dirt, foreign objects, deformation, scratches, or damage. Visual inspection is typically required to reject defective products. Currently, existing image inspection systems can photograph capacitors using a camera and analyze the images to identify any defects. However, simply using an image inspection system to capture images of capacitors placed on a conveyor belt cannot inspect multiple locations on the capacitor. Furthermore, the camera is prone to focusing errors, making it difficult to identify defects, resulting in low accuracy in visual inspection of capacitors.

[0003] Existing solutions involve using multiple processes to inspect the appearance of capacitors at different locations and rotating the capacitor to inspect multiple angles. However, this method suffers from poor imaging due to capacitor instability caused by rotation, low inspection efficiency, and complex mechanical structure, resulting in high costs. Therefore, there is an urgent need to invent a rotary capacitor appearance inspection device. Utility Model Content

[0004] One of the objectives of this invention is to provide a rotary capacitor appearance inspection device that addresses the shortcomings of existing technologies. This device features stable capacitor posture, stable camera imaging, high recognition rate of appearance defects, and high inspection efficiency.

[0005] To solve the above-mentioned technical problems, this application adopts the following technical solution: A rotary capacitor appearance inspection device is provided, comprising: a mounting base; a clamping and rotating mechanism mounted on the mounting base, the clamping and rotating mechanism including a clamping structure, a rotating structure, and a driving component, the output end of the driving component being connected to the rotating structure, the clamping structure being uniformly arranged along the outer periphery of the rotating structure for conveying capacitors along the rotation direction of the rotating structure; and multiple inspection stations arranged along the rotation direction of the clamping and rotating mechanism, each inspection station including a light source, a camera assembly, and multiple reflective lenses, the camera assembly for acquiring capacitor appearance information, the light source for illuminating and imaging the capacitor, and the reflective lenses for reflecting the image of the capacitor's inspected surface onto the camera assembly.

[0006] Furthermore, each of the inspection stations is provided with a clearance groove that runs through the rotation direction of the clamping and rotating mechanism.

[0007] Furthermore, one of the detection stations is a body station, in which the camera assembly is vertically mounted on the top of the capacitor, the light source is a coaxial ring-shaped parallel light source located below the camera assembly, and the reflective mirrors are set to 4 pieces, which are evenly arranged around the bottom of the capacitor.

[0008] Furthermore, one of the detection stations is a character station, in which the camera assembly is vertically mounted on top of the capacitor, the light source is a columnar light source surrounding the sidewall of the capacitor, and the reflective mirrors are set to 6 pieces, which are evenly arranged on the inner wall of the columnar light source.

[0009] Furthermore, one of the detection stations is a safety valve station. In the safety valve station, the camera assembly is vertically mounted on the top of the capacitor, the light source is a coaxial ring-shaped parallel light source located below the camera assembly, and there are four reflective lenses, which are evenly arranged around the top of the capacitor.

[0010] Furthermore, one of the detection stations is a camera head station, in which the camera assembly is vertically mounted on top of the capacitor, the light source is a columnar light source, the columnar light source is arranged around the top of the capacitor, and there are 6 reflective lenses, which are evenly arranged around the top of the columnar light source.

[0011] Furthermore, the angles between the reflective lens and the top of the capacitor are all different.

[0012] Furthermore, it also includes a fixed frame and a movable plate, the movable plate being fixedly connected to the fixed frame, the movable plate being able to be connected to different positions of the fixed frame, the movable plate connecting the light source, the reflective lens and the camera assembly, and being used to adjust the positions of the light source, the reflective lens and the camera assembly.

[0013] Furthermore, the clamping structure includes multiple grippers for gripping and releasing the capacitor.

[0014] Furthermore, it also includes a sorting mechanism, which comprises a collection bin and a good product unloading structure. The collection bin is used to receive defective capacitors, and the good product unloading structure is used to unload good capacitors. The detection station is electrically connected to the clamping and rotating mechanism and is used to control the release of the capacitor by the clamping structure. The beneficial effects of this utility model are as follows: The detection station set in this application uses a reflective lens to simultaneously reflect the image of the capacitor from various angles to the camera assembly for shooting. It can simultaneously collect 360° appearance information of the capacitor, without the need to rotate the capacitor for shooting. The structure is simple and efficient, and the capacitor posture is stable, resulting in stable imaging. This application sets multiple detection stations and arranges them along the rotation direction of the clamping and rotating mechanism, so that the clamping and rotating mechanism completes the detection of multiple positions of the capacitor during rotation by passing through different detection stations.

[0019] Although this application discloses preferred embodiments as described above, it is not intended to limit the claims. Any person skilled in the art can make several possible changes and modifications without departing from the concept of this application. Therefore, the scope of protection of this application should be determined by the scope defined in the claims of this application.

[0020] like Figure 1-3 As shown, this application provides a rotary capacitor appearance inspection device, including: a mounting base 1; a clamping and rotating mechanism 2, mounted on the mounting base 1, the clamping and rotating mechanism 2 including a clamping structure 21, a rotating structure 22, and a driving component 23, the output end of the driving component 23 being connected to the rotating structure 22, the clamping structure 21 being uniformly arranged along the outer periphery of the rotating structure 22, used to transport the capacitor along the rotation direction of the rotating structure 22; and multiple inspection stations 3, arranged along the rotation direction of the clamping and rotating mechanism 2, each inspection station 3 including a light source 31, a camera assembly 32, and multiple reflecting mirrors 33, the camera assembly 32 being used to acquire capacitor appearance information, the light source 31 being used to illuminate and image the capacitor, and the reflecting mirrors 33 being used to reflect the image of the capacitor's inspected surface onto the camera assembly 32.

[0021] The applicant discovered that existing appearance inspection equipment requires rotating the capacitor during the inspection process to ensure inspection from multiple angles. However, the capacitor's instability during inspection leads to unstable images, and this instability also places high demands on the camera. Therefore, the inventor uses a reflective mirror 33 to reflect multiple angle views of the capacitor to the camera, allowing the camera to capture these views. This eliminates the need for rotating the capacitor to capture images from multiple angles, thus enabling the camera to capture images from motion. By changing to static shooting, images from all angles are captured at the same time, eliminating image registration errors and time delays caused by capacitor movement or rotation. This makes the camera's imaging of the capacitor more stable and improves the recognition rate of appearance defects. Moreover, by eliminating the capacitor rotation structure 22, the overall structure is simpler. By setting up a clamping rotation mechanism 2 and arranging each inspection station 3 along the rotation direction, the functions of overall capacitor transfer and capacitor posture fixation can be completed. Furthermore, since the capacitor shooting process only requires taking one static picture to meet the shooting requirements, there is no need to shoot the entire capacitor rotation process, which improves the efficiency of capacitor appearance inspection.

[0022] The clamping structure 21 can clamp the capacitor. The rotating structure 22 rotates under the drive of the driving component 23, which in turn drives the clamping structure 21 to rotate. The driving component 23 can be a motor or other device that can drive the rotating structure 22 to rotate, so that the capacitor is transported along the rotation direction. During the transport process, it passes through multiple different detection stations 3 for detection. The detection device can control the imaging quality of the capacitor by setting the angle of the light source 31 and the reflective lens 33. Multiple reflective lenses 33 can reflect the capacitor from multiple angles to the camera assembly 32 to complete the shooting. When shooting, the rotating structure 22 remains stationary to ensure the imaging quality.

[0023] Preferably, each of the testing stations 3 is provided with a clearance groove 34 that runs through the rotation direction of the clamping rotating mechanism 2. The size of the clearance groove 34 is matched with the size of the capacitor, so that the capacitor can directly enter the appropriate position of the testing station 3 during the rotation of the rotating structure 22. The clearance groove 34 makes it easier for the capacitor to pass through different testing stations 3 without adjusting the position of the capacitor, thus improving the testing efficiency.

[0024] like Figure 4As shown, one of the inspection stations 3 is the body station 35. In the body station 35, the camera assembly 32 is vertically mounted on the top of the capacitor. The light source 31 is a coaxial ring-shaped parallel light source 311 set below the camera assembly 32. There are 4 reflective lenses 33, which are evenly arranged around the bottom of the capacitor. When inspecting the body of the capacitor, it is necessary to inspect the side of the capacitor. Setting the light source 31 as a coaxial ring-shaped parallel light source 311 enhances the side texture, making it easier to detect damage on the side of the capacitor. It can also avoid the influence of characters on the inspection and reduce reflection. The 4 reflective lenses 33 can meet the requirement of covering the entire 360° side, satisfying multi-angle coverage at the lowest cost.

[0025] like Figure 5 As shown, one of the detection stations 3 is a character station 36. In the character station 36, the camera assembly 32 is vertically mounted on the top of the capacitor. The light source 31 is a cylindrical light source 312, which surrounds the side wall of the capacitor. There are 6 reflective lenses 33, which are evenly distributed on the inner wall of the cylindrical light source 312. To reduce the influence of side textures such as unevenness when detecting characters on the capacitor, the cylindrical light source 312 is used. When the light source 31 illuminates the side of the capacitor, it forms a uniform diffuse reflection, reducing shadows and the influence of surface textures and unevenness, thus improving the accuracy of character detection. The reflective lenses 33 are placed inside the light source 31, which is conducive to adjusting the angle of the reflective lenses 33. By controlling the appropriate angle of the reflective lenses 33, the viewing angle deviation can be reduced, thus reducing the influence of the viewing angle deviation on the characters. The use of 6 lenses can reduce distortion and improve the accuracy of character detection.

[0026] like Figure 6 As shown, one of the detection stations 3 is the safety valve station 37. In the safety valve station 37, the camera assembly 32 is vertically mounted on the top of the capacitor. The light source 31 is a coaxial ring-shaped parallel light source 311 set below the camera assembly 32. There are 4 reflective lenses 33, which are evenly arranged around the top of the capacitor. The safety valve is set on the top of the capacitor. By setting the reflective lenses 33 on the top of the capacitor, the image on the top of the capacitor can be accurately reflected to the camera assembly 32 through the reflective lenses 33.

[0027] like Figure 7As shown, one of the inspection stations 3 is the capacitor head station 38. In the capacitor head station 38, the camera assembly 32 is vertically mounted on the top of the capacitor. The light source 31 is a cylindrical light source 312, which is arranged around the top of the capacitor. There are 6 reflective lenses 33, which are evenly arranged around the top of the cylindrical light source 312. The capacitor head is a structure that connects the top of the capacitor to the external circuit. It generally has a three-dimensional structure. The inspection of the capacitor head requires the capacitor head to be inspected without blind spots. Through the combination of the cylindrical light source 312 and the 6 reflective lenses 33, the top surface and the entire circumference of the capacitor head can be acquired simultaneously in a single shot, realizing high-efficiency and blind-spot-free automated inspection.

[0028] More preferably, the angles between the reflective lens 33 and the top of the capacitor are different. By setting the lens at different angles, more information about the capacitor can be obtained, thereby more accurately determining whether the capacitor is faulty.

[0029] Preferably, the device also includes a fixed frame 11 and a movable plate 12. The movable plate 12 is fixedly connected to the fixed frame 11 and can be connected to different positions of the fixed frame 11. The movable plate 12 connects to the light source 31, the reflective lens 33, and the camera assembly 32, and can be used to adjust the positions of the light source 31, the reflective lens 33, and the camera assembly 32. By setting the fixed frame 11 and the movable plate 12, the distance between the reflective lens 33, the camera assembly 32, and the capacitor can be adjusted by changing the position of the movable plate 12 on the fixed frame 11, so that the appearance inspection equipment of this application can be adapted to different types of capacitors.

[0030] Preferably, the clamping structure 21 includes multiple grippers for gripping and releasing capacitors. The grippers can grip and release capacitors so that the process of loading and unloading capacitors can be carried out by the grippers. Multiple grippers can be set to detect multiple capacitors at the same time. Preferably, the distance between different grippers and the distance between different detection stations 3 are matched so that when each rotation stops for photo detection, there are capacitors being detected at each detection station 3, forming a production line.

[0031] Preferably, the system also includes a sorting mechanism 4, which comprises a collection bin 41 and a good product unloading structure 42. The collection bin 41 is used to receive defective capacitors, and the good product unloading structure 42 is used to unload good capacitors. The detection station 3 is electrically connected to the clamping and rotating mechanism 2 and is used to control the release of the capacitors by the clamping structure 21. By controlling the release position of the clamping mechanism on the capacitors through the detection result of the detection station 3, the sorting of good and defective capacitors can be completed, thereby improving the level of automation. The above description illustrates and describes several preferred embodiments of the present invention. However, as mentioned above, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be modified within the scope of the present invention through the above teachings or the technology or knowledge in related fields. Modifications and changes made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
