[0027] In use, the workpiece to be tested is first placed inside the vibratory feeder. Since the circular vibratory feeder 4 is set inside the vibratory feeder, the messy workpiece can be arranged neatly and fed into the linear vibratory feeder 5. Then, under the action of the linear vibratory feeder 5, the workpiece is conveyed out in a straight line. As the workpiece moves, when the workpiece reaches the other end of the transmission component 6, the horizontal cylinder 7 drives the vertical cylinder 8 to move to the position above the workpiece. Then, the movable end of the vertical cylinder 8 picks up the workpiece through the workpiece picking head 20 and places the workpiece inside the workpiece fixture 19.

[0030] With the help of detection components, the equipment can automatically perform multi-process inspections at the workstation and can put the workpieces into different material boxes according to the test results, thereby realizing fully automated inspection and classification from input to output, which effectively improves the working efficiency of the equipment.

[0031] In operation, the motor is started, and the moving end of the motor drives the turntable to rotate synchronously. The rotation of the turntable drives the worktable 9 to rotate synchronously. The worktable 9 transports the workpiece to the confirmation station 10. The presence sensor at the confirmation station 10 confirms the presence of the workpiece and records its status. Then, the workpiece is transported to the low-pressure test station 11. The low-pressure test station 11 performs vacuum testing on the workpiece to detect the flow rate and records the test results. Next, the workpiece is transported to the high-pressure test station 12. The high-pressure test station 12 performs air inflation testing on the workpiece and records the test results. Next, the workpiece is transported to the negative pressure test station 13. The negative pressure test station 13 performs air inflation testing on the workpiece and records the test results. Finally, the workpiece is transported to the unloading station 14. The unloading station 14 blows the workpiece into the single-axis robot arm.

[0032] Specifically, the bottom of the workbench 9 is fixedly connected to the inside of the frame 1, the confirmation station 10 is fixedly connected to the inside of the workbench 9, the low-pressure test station 11 is fixedly connected to the inside of the workbench 9, the high-pressure test station 12 is fixedly connected to the inside of the workbench 9, the negative-pressure test station 13 is fixedly connected to the inside of the workbench 9, the unloading station 14 is fixedly connected to the inside of the workbench 9, the outer surface of the NG1 unloading frame 15 is fixedly connected to the inside of the frame 1, the outer surface of the NG2 unloading frame 16 is fixedly connected to the inside of the frame 1, the outer surface of the NG3 unloading frame 17 is fixedly connected to the inside of the frame 1, the OK unloading frame 18 is fixedly connected to the inside of the frame 1, the top of the workpiece clamp 19 is fixedly connected to the movable end of the vertical cylinder 8, and the bottom of the workpiece picking head 20 is fixedly connected to the outer surface of the workbench 9.

[0033] Working principle: In actual use, the workpiece to be tested is first placed inside the vibratory feeder. Since the circular vibratory feeder 4 is set inside the vibratory feeder, the messy workpiece can be arranged neatly and fed into the linear vibratory feeder 5. Then, under the action of the linear vibratory feeder 5, the workpiece is conveyed out in a straight line. As the workpiece moves, when the workpiece reaches the other end of the transmission component 6, the horizontal cylinder 7 drives the vertical cylinder 8 to move to the position above the workpiece. Then, the movable end of the vertical cylinder 8 picks up the workpiece through the workpiece picking head 20 and places the workpiece inside the workpiece clamp 19. This realizes the automated operation from workpiece arrangement to loading, effectively reducing manual intervention and avoiding errors caused by human factors, thereby significantly improving work efficiency and accuracy.

[0034] Then the motor is started. The moving end of the motor drives the turntable to rotate synchronously. The rotation of the turntable drives the worktable 9 to rotate synchronously. The worktable 9 transports the workpiece to the confirmation station 10. The presence sensor at the confirmation station 10 confirms the presence of the workpiece and records its status. Next, the workpiece is transported to the low-pressure test station 11. The low-pressure test station 11 performs vacuum testing on the workpiece to detect the flow rate and records the test results. Then, the workpiece is transported to the high-pressure test station 12. The high-pressure test station 12 performs air inflation testing on the workpiece and records the test results. Finally, the workpiece is transported to the negative pressure test station 12. The test station 13, a negative pressure test station, inflates the workpiece to test the flow rate and records the test results. Then, the workpiece is conveyed to the unloading station 14, which blows the workpiece into a single-axis robot arm. The single-axis robot arm moves the workpiece to the corresponding unloading frame based on the test results and places the workpiece into the corresponding frame. This system can automatically perform multi-process inspections at the stations and unload the workpiece into different frames according to the test results, thereby achieving fully automated inspection and classification from input to output, effectively improving the equipment's working efficiency.
