[0022] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0023] See also Figure 1-Figure 3 , Figure 1 It is a first three-dimensional structural schematic diagram of the roundness detection device provided by an embodiment of the utility model; Figure 2 It is a second three-dimensional structural schematic diagram of the roundness detection device provided in an embodiment of the utility model; Figure 3 yes Figure 2The enlarged view of A in the figure. The roundness detection device of the utility model includes a frame 11, a clamping assembly 12 and a detection assembly 13. The clamping assembly 12 includes a robot 121 and a clamping claw 122. The clamping claw 122 is installed at the end of the robot 121 to clamp parts. The robot 121 is installed on the frame 11 to drive the clamping claw 122 to move. The detection assembly 13 includes a detection base, a camera 131 and a shielding plate 132. The detection base and the shielding plate 132 are both arranged on the frame 11. The camera 131 is fixed on the detection base and faces the shooting image of the shielding plate 132. The robot 121 can drive the clamping claw 122 to move to a position between the camera 131 and the shielding plate 132.

[0024] When performing roundness detection on shaft parts, the parts are placed on the frame 11, and the robot 121 drives the clamp 122 to move and clamp the parts. The parts are moved to the position between the camera 131 and the baffle 132 by the robot 121. The parts are photographed by the camera 131, and during the shooting process, the robot 121 controls the clamp to rotate intermittently, so as to obtain multiple pictures of the parts at different angles. The roundness of the parts can be detected by comparing and analyzing the multiple pictures. When the camera 131 is shooting the part image, the part is between the camera 131 and the baffle 132. Therefore, the baffle 132 can isolate the external image interference, so that the image shot by the camera 131 only contains the parts, which is convenient for the subsequent analysis of the roundness of the parts from the image.

[0025] During the above-mentioned inspection process, the robot 121 controls the fixture to rotate intermittently, so that the fixture rotates with the central axis of the part as the axis to ensure that the reference of the camera 131 remains consistent when taking pictures of the part at different angles, thereby reducing the tediousness of subsequent analysis of multiple pictures and improving the accuracy of part roundness detection.

[0026] The utility model adopts a robot 121 to clamp parts, and adopts a camera 131 to capture the image of the parts, and finally detects the roundness of the parts from the image. Compared with the roundness detector in the prior art, the roundness detection device 1 of the utility model has a lower manufacturing cost, and can also realize the roundness detection of shaft parts, has a high cost performance, and is suitable for use by more small and micro enterprises.

[0027] See also Figure 3In an embodiment of the utility model, the detection base includes a fixed base 133 and a first slider 134, the fixed base 133 is fixed on the frame 11, the first slider 134 is slidably connected to the fixed base 133, and the camera 131 is connected to the first slider 134 to adjust the distance between the camera 131 and the baffle 132 under the sliding of the first slider 134.

[0028] By slidably connecting the first slider 134 with the fixing seat 133 and installing the camera 131 on the first slider 134, the camera 131 can be driven to move synchronously when the slider slides along the fixing seat 133, thereby adjusting the position of the camera 131 so that the camera 131 can shoot parts of different diameters. That is, when the diameters of the parts are different, the camera 131 will be out of focus when the distance from the part is close or far. Therefore, the focus of the camera 131 can be adjusted by sliding the first slider 134 to avoid the problem of defocusing when shooting the part image and affecting the roundness detection result.

[0029] In an embodiment of the utility model, the detection base also includes a second slider 135, which is slidably connected to the fixed base 133, and the first slider 134 is slidably connected to the second slider 135 to adjust the height of the camera 131 on the frame 11 under the sliding of the second slider 135.

[0030] By slidably connecting the second slider 135 to the fixed base and slidably connecting the first slider 134 to the second slider 135, the distance between the first slider 134 and the baffle 132 can be adjusted when the first slider 134 slides relative to the second slider 135, and the height of the camera 131 on the frame 11 can be adjusted when the second slider 135 slides relative to the fixed base. When the length of the part to be inspected is long, the height of the camera 131 can be adjusted by adjusting the height of the second slider 135 on the fixed base, so that the camera 131 can shoot the long parts and analyze the roundness of the parts from the captured images.

[0032] When conveying parts, the conveyor belt 142 carries the parts through the material transport plate and transports the parts out of the storage hopper 141 when the conveyor belt 142 rotates, so that the robot 121 can grab the parts from the transported parts for roundness detection, thereby realizing unmanned operation of part roundness detection and improving the detection efficiency of part roundness detection.

[0033] In an embodiment of the utility model, the conveying assembly 14 includes a vibration plate 143, and the vibration plate 143 is arranged on one side of the frame 11. The conveyor belt 142 extends out of one end of the storage hopper 141 and is aligned with the vibration plate 143. A feeding plate connected to the vibration plate 143 is arranged on the frame 11.

[0034] The vibration plate 143 is set on one side of the frame 11 and the conveyor belt 142 is arranged in alignment with the vibration plate 143, so that when the conveyor belt 142 conveys the parts, the parts on the material transport plate can be transferred to the vibration plate 143. After the vibration of the vibration plate 143, the angle of each part after being discharged from the vibration plate 143 is kept consistent, so that the robot 121 can drive the clamp to clamp the part, and then the robot 121 can drive the part to the position between the camera 131 and the baffle plate 132, so that the camera 131 can take pictures of the parts and analyze the roundness of the parts from the image.
