Detailed Implementation

[0020] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0021] Example: A flip-plate device for quality inspection of plastic casings, such as... Figures 1-6As shown, the system includes a mounting frame 1, a belt conveyor 2, a connecting plate 3, a conveyor plate 4, a connecting frame 5, a vision sensor 6, a first mounting plate 7, a rotating frame 8, a pneumatic motor 9, an air pipe 10, a second mounting plate 11, a bidirectional lead screw 12, a guide rod 13, a moving block 14, a locking block 15, a docking frame 16, a third mounting plate 17, a sliding rod 18, a sealing plate 19, a spring 20, a connecting rod 21, a scale strip 22, a guide plate 23, and a sponge pad 24. The belt conveyor 2 is installed inside the mounting frame 1. Connecting plates 3 are symmetrically installed on the left and right sides of the rear side of the mounting frame 1. Each connecting plate 3 has a conveyor plate 4 installed on it, and each conveyor plate 4 is connected to a connecting frame 5. Each connecting frame 5 has a vision sensor installed inside it. Sensor 6 captures images of the plastic shell during the conveying process, identifying defects and whether clips are installed. First mounting plates 7 are symmetrically mounted on the mounting frame 1, and a rotating frame 8 is rotatably connected between the two first mounting plates 7, driving the entire clamping device to rotate and complete the flipping operation of the plastic shell. A pneumatic motor 9 is mounted on the right first mounting plate 7, and an air pipe 10 is connected to the pneumatic motor 9 to supply air, forming a complete pneumatic drive circuit. Multiple second mounting plates 11 are connected to the rotating frame 8, and a bidirectional lead screw 12 is rotatably connected between each pair of adjacent second mounting plates 11 on the left and right sides, and a guide rod is connected between each pair of adjacent second mounting plates 11 on the left and right sides. 13. Each bidirectional lead screw 12 is threaded with a movable block 14. Two movable blocks 14 slide with corresponding guide rods 13. Each movable block 14 has a locking block 15 inside. Each locking block 15 has a mating frame 16 connected to its rear side for clamping and positioning the plastic shell, keeping the workpiece stable and preventing it from falling off during the flipping process. Each movable block 14 is equipped with a third mounting plate 17. Each third mounting plate 17 has a sliding rod 18 slidably connected inside. Each sliding rod 18 has a sealing plate 19 connected to its rear end. Each sealing plate 19 contacts and engages with the movable block 14 at its corresponding position to prevent the locking block 15 from accidentally falling off, thus providing a limiting and locking function. Each sealing plate 19 and the third mounting plate 17 at its corresponding position... Springs 20 are connected between the three mounting plates 17. A connecting rod 21 is connected to the outer end of each bidirectional lead screw 12. The connecting rod 21 passes through the second mounting plate 11, which facilitates the rotation of the bidirectional lead screw 12. Multiple scale bars 22 are evenly spaced on the rotating frame 8 to provide visual reference and help the operator accurately adjust the spacing between the docking frames 16, thereby improving the adjustment accuracy. A guide plate 23 is connected to each docking frame 16 to guide the plastic shell into the docking frames 16, avoiding placement failure or damage to the workpiece due to misalignment. A sponge pad 24 is connected inside each docking frame 16 to buffer the contact force between the plastic shell and the docking frame 16, prevent surface scratches or collision damage, and improve clamping safety.

[0022] When the plastic casing needs to be inspected and flipped, the operator first connects the air pipe 10 of this device to the starting component in the subsequent processing equipment (such as a fastening machine) to establish a shared air circuit system, providing power support for the subsequent pneumatic components. Then, the sliding rod 18 on the left is pushed forward, causing the sealing plate 19 connected to it to move, while compressing the internal spring 20. When the sealing plate 19 no longer blocks the through groove on the moving block 14, the sliding rod 18 is stopped. At this point, the appropriate docking frame 16 and locking block 15 are selected according to the size of the plastic casing. Insert them into the through slots of the movable block 14. After insertion, release the sliding rod 18. Under the action of the spring 20, the sliding rod 18 and the sealing plate 19 will automatically reset. The sealing plate 19 will limit and fix the locking block 15. Repeat the above operation to complete the installation of the remaining three docking frames 16. Then, according to the specific size of the plastic shell, rotate the connecting rod 21 to drive the bidirectional lead screw 12 to rotate. The rotation of the bidirectional lead screw 12 causes the movable blocks 14 on the left and right sides to move synchronously inward or outward along the guide rod 13, thereby adjusting the spacing between the docking frames 16. During the adjustment process, the scale bar 22 can be observed to assist in positioning and ensure accuracy. After adjusting one set of docking frames 16, the same operation is performed on the other docking frames 16 in sequence until all positions are adjusted in place. Then, the conveying system can be started, and the plastic shell to be inspected is conveyed forward through the conveyor plate 4. During the conveying process, the vision sensor 6 takes real-time pictures and identifies the plastic shell to determine whether it has been correctly installed with the buckle. If a shell without a buckle is found, the system will automatically send a signal to the control terminal to prompt the staff to remove the abnormal workpiece in time. The qualified plastic shell continues to move forward and falls between the docking frames 16. Then, the pneumatic motor 9 is started to drive the rotating frame 8 to rotate 170 degrees around the first mounting plate 7, so that the plastic shell is flipped. After the flipping is completed, the pneumatic motor 9 automatically reverses and drives the rotating frame 8 to return to its original position. The flipped plastic shell falls from the docking frame 16 onto the belt conveyor 2. The belt conveyor 2 is started to convey the workpiece forward to the next process. The equipment can repeat the above process to realize continuous quality inspection and automatic flipping operation of the plastic shell.

Any equivalent structural or procedural transformations made based on the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
