Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] like Figures 1-4The device shown is a quality inspection device for surface defects on the inner wall of a clutch bracket, used for quality inspection such as... Figure 5The diagram illustrates the inspection of the inner wall appearance quality of a clutch bracket part. The inspection device includes a turntable 1, a workpiece drive mechanism 3, and a vision inspection mechanism 4. The turntable 1 is mounted on a quality inspection workbench and is driven by a power element (not shown in the diagram). The power element uses a common electric motor. To accommodate the workstation setup, a stepper motor is configured on the turntable 1 to meet the requirement of intermittent rotation at a fixed angle. Along the rotation direction of the turntable 1, a loading station 11, a quality inspection station 12, a scrap removal station 13, and a good product output station 14 are sequentially arranged. These four stations are evenly distributed circumferentially around the center of the turntable 1. The turntable 1 has four circular recesses 15 formed in the recessed area of its surface. Each of these recesses 15 is evenly distributed circumferentially around the center of the turntable 1. A workpiece seat 2 is rotatably mounted within the inner groove 15. The workpiece seat 2 supports the clutch bracket part, and its inner diameter is adapted to the outer diameter of the clutch bracket part. The top of the workpiece seat 2 is open to facilitate the insertion of the clutch bracket part. The rotation angle of the turntable 1 is set to 90 degrees each time. After each rotation of the turntable 1, a clutch bracket part will enter the corresponding workstation. The clutch bracket part completes the loading operation at the loading station 11. The loading operation can be performed manually by workers or with the help of a robot. The workpiece drive mechanism 3 and the vision inspection mechanism 4 are installed at the quality inspection station 12. The workpiece drive mechanism 3 can be driven to the workpiece seat 2 at the quality inspection station 12. The vision inspection mechanism 4 includes a camera 41 that is movably mounted and lowered. The camera 41 is inserted into the inside of the clutch bracket part to collect image data of the inner wall. Since the camera 41 cannot rotate, only partial data of the inner wall of the part is collected at this time. This utility model design uses the workpiece drive mechanism 3 to drive the rotation of the workpiece seat 2 to realize the rotation of the clutch bracket part. After the clutch bracket part rotates, complete image data of the inner wall of the part can be obtained. The rotation of the clutch bracket part is generally set to rotate 2-3 times. The camera 41 is connected to a computer device (not shown in the figure). The collected inner wall image data is analyzed and compared by software on the computer device to detect whether there are any appearance defects. If there are appearance defects, the part needs to be removed in advance at the scrap rejection station 13. If there are no appearance defects, it is transferred to the good product station. The output station 14 outputs the product. This invention includes a scrap collection box 5 at the scrap removal station 13 to collect defective parts removed in advance. The good product output station 14 is equipped with a good product output conveyor belt 6. Good product parts are transported outwards via the good product output conveyor belt 6 after being removed. The scrap removal and good product removal operations can be performed manually by workers or with the aid of a robotic arm. This invention adopts a combination of rotary table assembly line operation and automatic detection, significantly improving quality inspection efficiency. The images of the inner walls of the parts collected by this invention are analyzed and compared by computer, significantly improving the accuracy of quality inspection compared to traditional manual quality inspection. The application of this invention can greatly reduce the labor intensity and workload of workers, meeting the production needs of cost reduction and efficiency improvement.
[0024] like Figure 2 As shown, the height of the workpiece seat 2 is less than the height of the clutch bracket component. This ensures that the clutch bracket component is partially exposed in the vertical direction after installation, meeting the requirements for gripping operations. A drive column 21 is vertically and fixedly connected to the bottom surface of the workpiece seat 2. The bottom end of the drive column 21 passes through the turntable 1 and extends downwards, where a transmission wheel 22 is fixedly connected. The transmission wheel 22, through the drive column 21, links with the workpiece seat 2. Rotating the transmission wheel 22 causes the workpiece seat 2 to rotate. The workpiece drive mechanism 3 includes a sliding frame 31, pulleys 32, a belt 33, and a first push cylinder 36. The three pulleys 32 are rotatably mounted on the top of the sliding frame 31. Figure 4 As shown, three pulleys 32 are arranged in a triangular pattern. A belt 33 is driven and mounted on the three pulleys 32. A motor 34 is mounted on the sliding frame 31. The output end of the motor 34 is connected to one of the pulleys 32, which is the driving pulley. After the motor 34 starts, it drives the three pulleys 32 to rotate synchronously through the belt 33. A guide rail 35 is laid under the sliding frame 31. The sliding frame 31 is movably mounted on the guide rail 35. The direction of movement of the sliding frame 31 is along the length of the guide rail 35. The sliding frame 31 needs to be designed in a linear movement mode so that the belt 33 can contact or move away from the drive wheel 22 of the workpiece seat 2. When the belt 33 contacts the drive wheel 22 of the workpiece seat 2, it can drive the workpiece seat 2 to rotate synchronously. When the belt 33 moves away from the workpiece seat 2... When the transmission wheel 22 is in motion, the turntable 1 can rotate. The first push cylinder 36 is horizontally mounted on the side of the sliding frame 31. The piston rod end of the first push cylinder 36 is connected to the side of the sliding frame 31. The sliding frame 31 is driven to move back and forth by the extension and retraction of the piston rod of the first push cylinder 36. In order to drive the workpiece seat 2, the wheel wall of the transmission wheel 22 is made into a rough surface, and the outer belt surface of the belt 33 is also made into a rough surface. After the sliding frame 31 moves towards the workpiece seat 2, the outer belt surface of the belt 33 contacts the wheel wall of the transmission wheel 22 to form a friction transmission effect (the workpiece seat 2 and the clutch bracket parts are relatively light, and the requirements can be met by friction transmission), thereby driving the rotation of the workpiece seat 2 and the clutch bracket parts.
[0025] like Figure 2 As shown, the visual inspection mechanism 4 also includes a stand 42 and a lifting drive element 43. The top of the stand 42 is provided with a crossbeam 421, and the lifting drive element 43 is installed on the crossbeam 421. The camera 41 is connected and installed on the lifting drive element 43. The lifting drive element 43 drives the lifting movement of the camera 41. After the camera 41 descends, it can be inserted into the inside of the clutch bracket part. At this time, the quality inspection operation is performed. The turntable 1 can only be rotated again after the camera 41 returns to the upper limit position. After the camera 41 returns to the upper limit position, the part is not interfered with in the movement path, and the turntable 1 can rotate normally.
[0026] like Figure 2As shown, the lifting drive element 43 includes a second push cylinder 431 and an electrical board 432. The second push cylinder 431 is installed vertically downwards, and the electrical board 432 is fixedly connected to the piston rod end of the second push cylinder 431. The extension and retraction of the piston rod of the second push cylinder 431 drives the lifting and lowering of the electrical board 432. The camera 41 is fixedly installed on the surface of the electrical board 432, near the bottom of the surface. The camera 41 moves up and down with the electrical board 432. The lens of the camera 41 faces the inner wall of the clutch bracket part. Light strips 433 are installed on both sides of the lens of the camera 41, and the light strips 433 on both sides form a lighting effect so that the camera 41 can capture a clean image. In this utility model, a linkage plate 434 is fixedly connected to the side of the electrical board 432. The linkage plate 434 also moves up and down with the electrical board 432. The visual inspection mechanism 4 also includes a limiting element 44, which includes a limiting frame 441. The limiting frame 441 is fixedly installed below the crossbeam 421. The turntable 1 is equipped with an upper limit switch 442 and a lower limit switch 443. The upper limit switch 442 is located at the upper limit of the linkage plate 434, and the lower limit switch 443 is located at the lower limit of the linkage plate 434. During the lifting and lowering motion, the linkage plate 434 contacts the upper limit switch 442 and the lower limit switch 443 respectively. Both the upper limit switch 442 and the lower limit switch 443 are contact-type trigger switches. The upper limit switch 442 can provide a start signal to the power element of the turntable 1. The turntable 1 can only rotate when the linkage plate 434 triggers the upper limit switch 442 (at this time, the camera 41 and the electrical board 432 are at the upper limit and will not cause a collision). The lower limit switch 443 provides a start signal to the camera 41, the light strip 433 and the workpiece drive mechanism 3. When the lower limit switch 443 is triggered, it means that the camera 41 has descended to the correct position. The camera 41 and the light strip 433 can start image acquisition, and the workpiece drive mechanism 3 can create the rotation effect of the part.
[0027] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
