Description

Technical Field

[0001] This utility model relates to the field of parts inspection technology, specifically a parts defect detection platform. Background Technology

[0002] Defect detection is a quality control technology that uses machine vision to automatically identify and evaluate defects such as spots, pits, and scratches on the surface of objects. This technology is widely used in industrial fields with strict requirements for appearance, such as metal surfaces, glass surfaces, and electronic components. It mainly uses image processing algorithms combined with multi-light source collaborative imaging systems to enhance the imaging effect of surface defects of different materials through dark field, bright field, and light transmission methods.

[0003] According to Chinese Utility Model Application No. 202421914085.X, a visual inspection device for parts is proposed. The utility model describes that "through the cooperation of the inspection mechanism, the first motor can drive the first lead screw to rotate, thereby driving the first slider to move, which facilitates the adjustment of the camera position, so that the camera can accurately capture the whole picture of the part. The second motor can drive the second slider to rise and fall, thereby adjusting the height of the camera, ensuring that the camera can capture the best inspection angle, and ensuring that the camera can clearly capture the image of the part, avoiding inspection errors caused by poor angle, thereby improving the stability and reliability of the inspection results."

[0004] The current visual inspection device for parts can only perform overall defect detection on circular parts, making it difficult to rotate the circular parts for local inspection, which affects the inspection effect and needs to be improved. Therefore, a part defect inspection platform is proposed to solve the above problems. Utility Model Content

The transparent baffle 8 is made of acrylic.

[0026] Specifically, the staff first places the circular part on top of the rotating mechanism 5, then uses the rotating mechanism 5 to rotate the circular part, and uses the inspection mechanism 3 to inspect the top of the circular part for defects. The inspection table 1, the protective chamber 2, and the shielding mechanism 6 shield the circular part, while the observation window 7 and the transparent baffle 8 facilitate observation. After one side is inspected, the circular part is flipped over to inspect the other side for defects. Finally, the rotating mechanism 5 is used to rotate the circular part, and the measuring mechanism 4 is used to inspect the size of the circular part. This allows for local inspection by rotating the circular part, improving the inspection effect.

[0027] In this embodiment, the detection mechanism 3 includes a bracket 31, which is fixedly connected to the top of the detection platform 1 and extends through the protective chamber 2. A baffle 32 that fits against the top of the protective chamber 2 is fixedly installed on the side wall of the bracket 31.

An infrared lamp 35 is fixedly installed on the top of the detection platform 1.

[0028] Specifically, the shadowless lamp 34, together with the measuring mechanism 4, inspects the dimensions of the circular part, and the infrared lamp 35, together with the camera 33, inspects the defects of the circular part, such as cracks and scratches.

[0029] In this embodiment, the measuring mechanism 4 includes a connecting frame, which is fixedly connected to the top of the detection table 1, and a laser sensor is threadedly installed on the side wall of the connecting frame via a second bolt.

[0030] Specifically, the laser sensor calculates the distance to the circular part by emitting a laser beam and receiving the reflected signal.

[0031] In this embodiment, the rotating mechanism 5 includes a first mounting frame 51, which is fixedly connected to the inner bottom wall of the detection table 1. A motor 52 is fixedly mounted on the inner top wall of the first mounting frame 51. The output end of the motor 52 passes through the first mounting frame 51 and is fixedly mounted with a rotating shaft 53. The infrared lamp 35 has a through hole that matches the rotating shaft 53. A second mounting frame 54 is fixedly mounted on the top of the first mounting frame 51. The rotating shaft 53 is rotatably connected to the second mounting frame 54 through a first bearing. The top of the rotating shaft 53 passes through the second mounting frame 54 and is detachably mounted with a base plate 55. A light shield 56 is detachably mounted on the top of the base plate 55. The light shield 56 passes through the base plate 55 through a third bolt and is threadedly connected to the second mounting frame 54. The center of the base plate 55 and the center of the light shield 56 are on the same straight line as the axis of the output end of the motor 52.

[0032] Specifically, by turning on the motor 52, the motor 52 drives the rotating shaft 53, the base plate 55, the light shield 56 and the central part to rotate, which facilitates the inspection of the circular part.

[0033] In this embodiment, the shielding mechanism 6 includes a connecting plate 61, which is fixedly connected to the side wall of the bracket 31. A chamber 62 is fixedly installed on the side wall of the connecting plate 61, and a first clamping plate 63 is fixedly installed on the side wall of the chamber 62. A shielding plate 64 is inserted into the inside of the first clamping plate 63. A bidirectional threaded rod 65 is rotatably installed on the inner side wall of the chamber 62 via a second bearing. The side of the bidirectional threaded rod 65 away from the inner side wall of the chamber 62 passes through the chamber 62 and is fixedly installed with a knob 66. Two threads are installed on the outer side of the bidirectional threaded rod 65. Two threaded sleeves 67 are fixedly mounted on the side walls of each threaded sleeve 67. The side wall of the chamber 62 is provided with a moving hole that matches the moving rod 68. The side of each moving rod 68 away from the threaded sleeve 67 passes through the chamber 62 and is fixedly mounted with a second clamping plate 69. The two second clamping plates 69 are used to clamp the two sides of the baffle plate 64. The baffle plate 64 matches the circular part. The inside of the first clamping plate 63 and the two second clamping plates 69 is provided with a clamping groove, and an anti-slip pad is fixedly installed inside the clamping groove.

[0034] Specifically, first, insert the shielding plate 64 that matches the circular part into the middle position inside the first clamping plate 63. Then, turn the knob 66. The knob 66 ​​drives the bidirectional threaded rod 65 to rotate. The bidirectional threaded rod 65 drives the two threaded sleeves 67 to move relative to each other. The two threaded sleeves 67 drive the two moving rods 68 and the two second clamping plates 69 to move relative to each other. The two second clamping plates 69 clamp the two sides of the shielding plate 64, so that the shielding plate 64 shields the area around the circular part, ensuring that the detection focus is concentrated on the surface of the part.

[0035] The working principle of the above embodiments is as follows:

[0036] The operator first places the circular part on top of the substrate 55, inserts the matching shielding plate 64 into the center of the first clamping plate 63, and rotates the knob 66 ​​to rotate the bidirectional threaded rod 65. The bidirectional threaded rod 65 drives the two threaded sleeves 67 to move relative to each other, and the two threaded sleeves 67 drive the two moving rods 68 and the two second clamping plates 69 to move relative to each other. The two second clamping plates 69 clamp the two sides of the shielding plate 64, so that the shielding plate 64 blocks the substrate 55. Then, the motor 52 is turned on to drive the rotating shaft 53, the substrate 55, the light shielding plate 56, and... The circular part rotates, and the infrared lamp 35 and camera 33 are turned on to detect defects in the circular part. The inspection table 1, protective chamber 2 and shielding plate 64 shield the circular part. The observation window 7 and transparent baffle 8 facilitate observation. After one side is inspected, the circular part is flipped over to inspect the other side for defects. Finally, the motor 52 is turned on to drive the rotating shaft 53, base plate 55, light shielding plate 56 and the circular part to rotate, and the shadowless lamp 34 and laser sensor are turned on to detect the size of the circular part. This allows for localized inspection by rotating the circular part, improving the inspection effect.
