Various examples may omit, substitute, or add various processes or components as needed. In addition, features described with respect to some examples may also be combined in other examples.

[0019] like Figures 1 to 3 As shown, a CCD visual inspection device according to an embodiment of the present invention includes a base 1, an inspection cabinet door 11 is provided on the base 1, a back mounting plate 13 is provided on the back of the inspection cabinet door 11, a fill light 12 is provided on the base 1, a display 14 is fixedly mounted on the back mounting plate 13, a plurality of inspection rotating fixtures 2 are slidably mounted on the base 1, a camera mounting plate 15 is provided on one side of the inspection cabinet door 11, a camera 16 is provided at the center of the camera mounting plate 15, the inspection rotating fixture 2 is used to limit the inspection workpiece, so as to facilitate the angle adjustment and rotation of the workpiece when passing through the interior of the inspection cabinet door 11, and the camera 16 is used to perform visual inspection on the workpiece; like Figures 4 to 6 As shown, the detection rotating fixture 2 includes a first connecting member 21, an adjusting member 22, a second connecting member 23, a rotating member 25, and an adsorption member 26. A slide rail is provided on the base 1, and a plurality of first connecting members 21 are installed on the slide rail. The side of the first connecting member 21 is provided with an adjusting member 22, the top of the first connecting member 21 is provided with a second connecting member 23, the end of the second connecting member 23 away from the side of the first connecting member 21 is provided with a rotating member 25, and the side of the rotating member 25 away from the side of the first connecting member 21 is provided with an adsorption member 26. The movement of the adjusting member 22 drives the second connecting member 23 to move up and down, and the lifting and lowering of the second connecting member 23 is used to adjust the angle of the rotating member 25. The movement of the rotating member 25 is used to adjust the angle of the adsorption member 26, so that the camera 16 can take pictures and detect the workpiece on the detection rotating fixture 2.

[0020] It should be noted that when visually inspecting a workpiece, it is not certain where the obstruction will occur. If conventional fixtures are used, it is difficult to control the clamping force for different workpieces. To address this issue, the following improvements have been made: First, align one of the planes of the workpiece with the adsorption part 26, and the side of the adsorption part 26 is provided with an air suction disk for adsorbing the workpiece, which can adsorb the workpiece in a position close to the adsorption part 26, and start the second connecting part 23 to adjust the position of the adsorption part 26 so that the first motor 212 is at the farthest end from the center of the adsorption part 26, and then start the first connecting part 21 to drive the second connecting part 23 to rotate, so as to adjust any angle of rotation of the workpiece on the adsorption part 26. After the adjustment is completed, start the slide rail on the base 1 to drive the detection rotating fixture 2 to move toward the direction close to the inside of the display 14. When the detection rotating fixture 2 passes through the camera mounting plate 15, the camera 16 on the camera mounting plate 15 will take a picture of the workpiece adsorbed on the side of the adsorption part 26. Since the position of the photo may be blocked, the position of the second connecting part 23 can be adjusted by adjusting the adjusting part 22, so that the second connecting part 23 can be vertically lifted and horizontally moved. The vertical lifting and horizontal movement of the second connecting part 23 can bring The rotating member 25 rotates, driving the adsorption member 26 at the end of the rotating member 25 to rotate, and photographing the workpiece at various angles on the adsorption member 26 to prevent the problem of obstruction caused by ordinary external fixtures, thereby improving the detection effect. When the detection rotating fixture 2 moves to the center position of the detection cabinet door 11, a camera is also provided at the bottom of the center position of the detection cabinet door 11, which can photograph the bottom of the workpiece to reduce the generation of blind spots. Until the detection rotating fixture 2 moves to the other end of the base 1, the visual detection function is completed. The adsorption member 26 on this device can be adsorbed with a plane of the workpiece to complete the clamping effect of the workpiece and reduce the blind spot of the field of view. When the first connecting member 21 is started, it can drive the adsorption member 26 to rotate and adjust the angle of the workpiece during detection to prevent the blind spot of the field of view when the second connecting member 23 moves. This improves the effect of visual detection, reduces the uneven force that the fixture may produce on the workpiece, and causes the problem of deformation of the workpiece, thereby improving the safety of the workpiece during detection.

[0022] It should be noted that a mounting rod 24 is provided on the side of the first connecting member 21, which can limit the position of the rotating member 25, and a placement frame 27 is provided at the lower part of the first connecting member 21. When the workpiece is adsorbed on the adsorption member 26, a simple comparison effect can be used to determine whether the workpiece will collide during the rotation process, thereby improving the safety during detection.

[0023] like Figures 4 to 6As shown, the first connecting member 21 includes a first fixed block 211 arranged on the top slide rail of the base 1, and a first motor 212 is arranged on the side of the first fixed block 211. The end of the first motor 212 passes through the first fixed block 211 and is connected to the second connecting member 23. An adjusting member 22 is fixedly installed on the top of the first fixed block 211, and the adjusting member 22 is used to adjust the position of the second connecting member 23.

[0024] It should be noted that the output shaft of the first motor 212 is provided with a second connecting member 23, and the end of the second connecting member 23 is connected to the rotating member 25. Therefore, when the first motor 212 is started, it can drive the second connecting member 23 and the rotating member 25 to rotate, thereby driving the adsorption member 26 to rotate. The rotation of the adsorption member 26 can rotate the workpiece adsorbed on the adsorption member 26, thereby adjusting the visual inspection angle of the workpiece, and the top of the first fixed block 211 is provided with an adjusting member 22. By adjusting the position of the adjusting member 22, the position of the second connecting member 23 can be adjusted, so that the adsorption member 26 can be detected in a plane parallel to the three-dimensional coordinate system, which is easy to determine the angle of the picture after taking the picture and improves the accuracy of the detection.

[0025] like Figures 4 to 6 As shown, the adjusting member 22 includes a second fixed block 221 fixedly mounted on the top of the first fixed block 211, a first U-shaped block 226 fixedly mounted on the side of the second fixed block 221, a second screw 225 is rotatably mounted inside the first U-shaped block 226, an external thread of the second screw 225 is threadedly mounted with a second connecting block 224, a first screw 223 is rotatably mounted inside the second connecting block 224, an external thread of the first screw 223 is threadedly mounted with a first connecting block 222, and the bottom of the first connecting block 222 is connected to the second connecting member 23.

[0026] It should be noted that a motor can be provided at the end of the first U-shaped block 226 away from the second fixed block 221. The output shaft of the motor is connected to the second screw 225, so that the second screw 225 can be driven to rotate, thereby driving the second connecting member 23 at the bottom to move, and the rotation of the first screw 223 can drive the first connecting block 222 to slide, and the bottom of the first connecting block 222 is connected to the second connecting member 23, thereby achieving the effect of driving the second connecting member 23 to move horizontally. In the initial state, the second connecting block 224 is at the nearest end close to the second fixed block 221, and the first connecting block 222 is located at the center outside the first screw 223, and the rotation of the second screw 225 can make the second connecting block 224 move away from the second fixed block 2 When the first screw 223 rotates and drives the first connecting block 222 to move toward the two ends of the second connecting block 224, the second connecting member 23 can be moved, thereby driving the rotating member 25 to rotate, so that the adsorption member 26 is parallel to a surface in the three-dimensional coordinate system, thereby facilitating the angle calculation after the photograph is formed. At the same time, a telescopic rod can be installed at the bottom of the first connecting block 222 to drive the second connecting member 23 to move up and down, thereby achieving the effect of parallelism of another surface in the three-dimensional coordinate system, which is convenient for determining the angle and shape after photographing.

[0028] It should be noted that the fourth U-shaped block 238 moves horizontally, which can drive the adsorption member 26 to rotate horizontally, and the fourth U-shaped block 238 moves up and down, which can drive the adsorption member 26 to rotate vertically, thereby driving the side workpiece of the adsorption member 26 to perform multi-angle detection. In the initial state, the limit slider 233 is located outside the first telescopic rod 231, so the third telescopic rod 237 can be oriented to any direction and angle, and the rotating member 25 and the adsorption member 26 at the end of the third telescopic rod 237 can also be oriented to any angle, which can facilitate the purpose of installation and adjustment. When the second screw 225 rotates, it drives the second connecting block 224 to move away from the second fixed block 221, and the first screw 223 is in a state as shown in FIG. Figure 5 When the state is reached, the fourth U-shaped block 238 moves, which can drive the second telescopic rod 232, the limiting slider 233 and the limiting protrusion 234 to move in the direction close to the rotating member 25, and the limiting slider 233 and the limiting protrusion 234 slide outside the third telescopic rod 237, so that the third telescopic rod 237 and the axis of the first motor 212 are in the same straight line, so that the adsorption member 26 is in the state as shown in FIG. Figure 5 state, so that the rotation direction of the adsorption member 26 can be determined, so that the picture after taking the photo can be calculated, and the rotation of the adsorption member 26 can also reduce the problem of occlusion and improve the accuracy of detection.

[0030] It should be noted that an external limiting block 253 is fixedly installed on the side of the third fixed block 251, and a rotating sphere 252 is movably installed inside the external limiting block 253. The two ends of the rotating sphere 252 are provided with a first protrusion 254 and a second protrusion 255, and the third fixed block 251 is provided with a plurality of rotation limiting grooves 256, so that when the first protrusion 254 rotates around the rotating sphere 252 as the center of the circle, the first protrusion 254 can be engaged with the rotation limiting groove 256, and when the third telescopic rod 237 moves horizontally, the first protrusion 254 can be engaged with the rotation limiting groove 256.

Therefore, by adjusting the position of the third telescopic rod 237, the position of the rotating sphere 252 sliding inside the external limit block 253 can be adjusted, thereby adjusting the direction and angle of the adsorption component 26.

[0031] like Figures 4 to 6 As shown, the adsorption member 26 includes an adsorption plate 261 fixedly mounted on the end of the second protrusion 255 , a first suction cup 262 is fixedly mounted on the side edge of the adsorption plate 261 , and a second suction cup 263 is fixedly mounted on the side center of the adsorption plate 261 .

[0032] It should be noted that the first suction cup 262 and the second suction cup 263 can be connected to an air suction machine. When the workpiece needs to be fixed on the adsorption plate 261, a plane on the workpiece can be used as a reference, and then this plane can be moved close to the position of the first suction cup 262 and the second suction cup 263. Then, the air suction machine is started, so that the first suction cup 262 and the second suction cup 263 can adsorb one of the planes of the workpiece, thereby completing the effect of limiting and fixing.
