[0022] Working principle:

[0023] 1. Bend pipe feeding mechanism 1: The operator puts the bent pipes into the mechanism in batches, and the device inside the mechanism will automatically feed the bent pipes to the discharge port one by one; when the bent pipes are empty, the mechanism will emit an audible and visual alarm to prompt the operator to replenish the bent pipes.

[0024] 2. Bend pipe inspection: The robot takes out the bend pipe from the outlet of the bend pipe feeding mechanism 1, and then moves it to the bend pipe inspection position, where a visual inspection system is installed. The robot constantly adjusts its posture to allow the visual system to inspect different positions of the bend pipe. If there are unqualified products, the robot will put them into the NG material box, otherwise they will be placed in the visual positioning station.

[0025] 3. Visual positioning: The visual system installed at this station measures the position of the 1# bushing installation hole on the elbow, and the servo mechanism adjusts the elbow to the optimal assembly position based on the measured hole position data.

[0026] 4. 1# bushing conveying mechanism 4: The bushing conveying device obtains the bushing from the corresponding bushing feeding device 18 according to the preset model and delivers it to the bushing assembly station.

[0027] 5. Bushing assembly: The servo mechanism presses the bushing into the 1# elbow bushing hole positioned in step 3.

[0028] 6. Support rod loading: The operator places the support rods in batches on the support rod loading chain plate line 6 mounting device. The mounting device is equipped with an error-proofing device. The motor drives the chain plate line to automatically send the support rods one by one to the discharge port to be taken out by the 5# robot.

[0029] 7. Support rod positioning: The support rod is pre-positioned through a set of mechanical structures such as cylinders.

[0030] 8. Pin inspection: The pin is fed into a special pipeline through a pin feeding device and then output. The pneumatic gripper cooperates with the slide cylinder to send the pin to the inspection station, where the length of the pin is inspected to avoid mixing of pins of different models. Pins with qualified length are then sent to the pin insertion position.

[0031] 9. Pre-installation of support rod: The wedge block combines the two components into place, and then guides the cylinder into the pin hole of the component to support the pin shaft. The pin-pushing cylinder moves to pre-install the pin shaft into the support rod assembly and guides the cylinder to retreat at the same time.

[0032] 10. Support rod riveting: After multiple cylinders have positioned the product well, the riveting machine works to rivet the pin and the support rod assembly. Multiple sensors are installed on the workstation to detect the riveting quality.

[0033] 11. Visual positioning: The visual system installed at this station measures the position of the 2# bushing installation hole on the elbow, and the servo mechanism adjusts the elbow to the optimal assembly position based on the measured hole position data.

[0034] 12. 2# bushing conveying mechanism 4: The bushing conveying device obtains the bushing from the corresponding bushing feeding device 18 according to the preset model and delivers it to the bushing assembly station.

[0035] 13. Bushing assembly: The servo mechanism presses the bushing into the 2# elbow bushing hole located in step 11.

[0036] 14. Loading the base: The operator places the bases in batches on the support rod loading chain plate line 6 mounting device, which is equipped with an error prevention device and a detection device. The motor drives the chain plate line to automatically send the bases one by one to the discharge port to be taken out by the 7# robot.

[0037] 15. Pre-installation of the base: The wedge block combines the two components into place, and then guides the cylinder into the pin hole of the component to support the pin shaft. The pin-pushing cylinder moves to pre-install the pin shaft into the base component and guides the cylinder to retreat at the same time.

[0038] 16. Base riveting: After multiple cylinders have positioned the product well, the riveting machine will rivet the pins and base components. Multiple sensors are installed on the workstation to detect the riveting quality.

[0039] 17. Inspection station 14: The 9# robot puts the assembled finished product into the inspection fixture, which is equipped with an array of cylinders and sensors to check whether the finished product is qualified.

[0040] 18. Finished product unloading: The 10# robot takes the finished product from the inspection fixture, and puts the finished product into the OK unloading mechanism or NG unloading mechanism according to the inspection results and waits for the operator to take it away.
