Embodiment 1

[0031] See figure 1, a surface defect detection device for auto parts includes a base 1, the bottom of the base 1 is evenly provided with a number of legs 15, the center of the bottom of the base 1 is fixedly connected to a motor 5, and the top of the base 1 is fixedly installed with a slide rail 3. The slide rail 3 is a ring structure, the slide rail 3 is rotatably connected with a detection platform 4, the bottom end of the detection platform 4 is fixedly connected with a rotating shaft 6, and the bottom end of the rotating shaft 6 runs through the base 1 and is rotatably connected On the motor 5, the axis of the rotating shaft 6 coincides with the axis of the detection platform 4, and the top of the base 1 is also fixedly connected with a dark box 2, and the dark box 2 is sleeved on the outside of the detection platform 4, and the top of the dark box 2 is embedded with a Observation window 10, the inner cavity of described observation window 10 is equipped with protective p...

Embodiment 2

[0034] See figure 2 , and the difference from Embodiment 1 is that: the top side of the base 1 is fixedly installed with a vertical rod 17 matched with the detection table 4, the vertical rod 17 is located inside the dark box 2, and the top of the vertical rod 17 is connected to the There is a swivel base 18, and an extension rod 19 is embedded on the swivel base 18. There is a sliding connection between the swivel base 18 and the extension rod 19. The end of the extension rod 19 close to the detection table 4 is fixedly connected with a fixed-point lamp 20. The swivel base 18 can drive the extension rod 19 to rotate, thereby adjusting the lighting angle of the fixed-point lamp 20. At the same time, the extension rod 19 pushes and pulls back and forth on the swivel base 18 to adjust the position of the fixed-point lamp 20 on the detection table 4, and then adjust the fixed-point lamp 20. The specific lighting position enables fixed-point observation of the workpiece, which ca...

Embodiment 3

[0036] See image 3 The difference from Embodiment 1 is that: the top of the base 1 is also fixedly connected with a stand 21 that matches the detection platform 4, the stand 21 is an L-shaped structure, and the inner cavity of the stand 21 is fixedly installed with Fixed plate 22, described fixed plate 22 is inclined setting, is embedded with spray device 23 on the fixed plate 22, sprays the workpiece on the detection table 4 by spray device 23, makes the workpiece performance to be attached with a large amount of tiny water droplets, Then, the camera 9 is used to take pictures, which is convenient for later workers to carry out comparative observation, so as to find small scratches on the surface of the workpiece, thereby further improving the detection quality of the workpiece.

Abstract

The invention discloses an automobile part surface defect detection device and a detection method thereof. The device comprises a base, wherein a motor is fixedly connected with the center of the bottom end of the base, slide rails are fixedly mounted at the top end of the base, a detection table is rotationally connected onto the slide rails, the bottom end of the detection table is fixedly connected with a rotating shaft, the bottom end of the rotating shaft penetrates through the base and is rotationally connected onto the motor, the top end of the base is also fixedly connected with a darkbox, the top wall of an inner cavity of the dark box is fixedly connected with a seat frame, multiple LED lamps and multiple cameras matched with the detection table are uniformly arranged on the seat frame, and a touch display screen is mounted on one side of the top end of the dark box; workpieces are directly placed on the detection table, then, under irradiation of the LED lamps, the camerasshoot the workpieces, pictures are directly displayed by the touch display screen, a worker can operate the touch display screen to amplify and observe details of the workpieces more carefully, so that the workpiece detection quality can be substantially improved, and discharge of scratched workpieces can be reduced to the greatest extent.

Description

technical field [0001] The invention relates to the technical field of auto parts inspection, in particular to an auto parts surface defect detection device and a detection method thereof. Background technique [0002] Auto parts are the various units that make up the whole car and a product that serves the car. There are many kinds of auto parts. With the improvement of people's living standards, people consume more and more cars, and the market for auto parts is getting bigger and bigger. In recent years, auto parts manufacturers are also developing rapidly. [0003] During the processing of some auto parts, surface flaw detection is required, especially for auto parts with high requirements on the external surface processing quality, it is necessary to judge whether there are scratches, pits and other defects on the surface of the workpiece, so as to prevent later surface spraying and affect the spraying quality. However, the existing inspection of accessories mainly re...
