[0040] The present invention is in use:

[0041] 1. The envelopes are fed by a flexible vibrating plate and photographed by a visual camera to solve the problem of feeding envelopes of different diameters (13-17mm) and lengths (12-17mm). One device can meet the requirements of multiple specifications. The visual camera confirms the size of the envelope by taking a photo to confirm whether it is the envelope required at the current stage. If so, it is grasped by the four-axis robot gripper mechanism.

[0042] 2. Feeding mechanism: 1. The visual camera takes a picture above the flexible vibration plate, guides the four-axis robot gripper mechanism to clamp the envelope, and puts it into the slide, and the envelope naturally rolls from the high end to the end. When the full fiber detects the envelope, the four-axis robot gripper mechanism stops discharging. 2. When the detection fiber detects that there is an envelope on the platform, the push rod cylinder extends, and the push rod pushes the envelope to the second three-claw finger, and the second three-claw finger clamps the envelope from the inner diameter of the envelope. Here, the automatic centering function of the second three-claw finger is used to fix envelopes of different diameters at the same center height, which is convenient for alignment with the center of the first three-claw finger. 3. The third lifting cylinder rises upward so that the center of the second three-claw finger is on the same axis as the center of the first three-claw finger.

[0043] 3. Positioning mechanism: 1. Manually fix the elbow on the fixture plate; 2. After placing the elbow, press the start button 34 with both hands, and the start button controls the rotation of the rotating cylinder; 3. Repeat the above actions to position the elbow on the outer periphery of the fixture plate.

[0044] 4. Arrangement mechanism: 1. Manually take a braided tube and place it according to the tooling position. The front end of the braided tube touches the baffle, which can be a trigger switch. After touching, the first clamp and the second clamp clamp the braided tube. 2. The first lifting cylinder moves down to move the baffle downward. 3. The first telescopic cylinder moves backward, and moves the second clamp backward to straighten (or straighten) the braided tube and the steel wire inside until the front end of the second clamp is flush with the front end of the braided tube. 4. After the first telescopic cylinder moves backward into place, the double-control solenoid valve that controls this cylinder is vented and exhausted, so that there is no compressed air in the first telescopic cylinder, and it is in a natural state.

[0045] 5. Transplanting mechanism: 1. The second telescopic cylinder of the transfer mechanism extends forward, the first three-claw finger clamps the outer periphery of the envelope on the second three-claw finger, and then the second telescopic cylinder retracts. 2. The transverse cylinder moves to the right so that the envelope and the braided tube are on the same axis, that is, the center of the first three-claw finger and the braided tube are on the same straight line. 3. The second telescopic cylinder extends forward and assembles the envelope to the outer periphery of the front end of the braided tube. 4. The third telescopic cylinder extends, and after the third clamp at the front end clamps the elbow, the third telescopic cylinder retracts. 5. The transverse cylinder moves to the left, and the second lifting cylinder is lifted at the same time; the reaming rod is set coaxially with the braided tube. 6. The fourth telescopic cylinder extends, and the reaming rod is inserted into the braided tube to expand the hole. After the hole is expanded, the fourth telescopic cylinder is reset. 7. The second lifting cylinder descends, so that the insertion end of the elbow is aligned with the braided tube, and they are also on the same axis. 8. The third telescopic cylinder extends forward to assemble the elbow into the braided tube, the third clamping jaw is released, and the third telescopic cylinder is reset. The assembly of an elbow tube is completed.
