The three main components of the transplanting mechanism: the first three-claw finger, the reaming rod, and the third clamping jaw can move forward and backward relative to the sorting mechanism, and the reaming rod and the third clamping jaw can also move up and down relative to the machine.

[0033] Preferably, the organizing mechanism also includes a baffle 23, which can abut and cooperate with the end face of one end of the braided tube. When one end of the braided tube abuts and cooperates with the baffle, the braided tube completes the positioning. It also includes a first lifting cylinder 24, which can be connected to the baffle.

A second three-claw finger 51 capable of clamping the envelope is provided on one side (front side) of the platform. The second three-claw finger can clamp the envelope from the inside, while the first three-claw finger can clamp the envelope from the outside. In other words, the second three-claw finger clamps the inner periphery of the envelope, while the first three-claw finger clamps the outer periphery of the envelope.

The feeding mechanism 10 also includes a third lifting cylinder 54 that can be connected to the second three-claw finger, so that the first three-claw finger and the second three-claw finger are on the same axis, making it easier for the first three-claw finger to clamp the envelope on the second three-claw finger.

The driving method is similar to that of the prior art, and will not be elaborated on again, nor will they be marked in the figure; the slide rails required for forward and backward, left and right movement are similar to those of the prior art, and will not be elaborated on again, nor will they be marked in the figure.

[0040] The utility model is in use:

[0041] 1. The envelopes are fed by a flexible vibrating plate and photographed by a visual camera, solving the problem of feeding envelopes of different diameters (13-17mm) and lengths (12-17mm). One device can meet 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, guiding the four-axis robot gripper mechanism to clamp the envelope and place it into the slide. The envelope naturally rolls from the high end to the end. When the full optical fiber detects the envelope, the four-axis robot gripper mechanism stops discharging. 2. When the detection optical 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. The second three-claw finger clamps the envelope from the inner diameter of the envelope. The automatic centering function of the second three-claw finger is used here 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 and the center of the first three-claw finger are on the same axis.

[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 to control the rotation of the rotary cylinder; 3. Repeat the above steps 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 equipped with a trigger switch. After the touch, the first clamp and the second clamp will clamp the braided tube. 2. The first lifting cylinder descends to move the baffle downward. 3. The first telescopic cylinder moves backward, taking the second clamp with it, and straightens the braided tube and the steel wire inside (or straightens it) 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 dual-control solenoid valve that controls this cylinder performs intermediate exhaust, 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 clamping claw at the front end clamps the elbow, the third telescopic cylinder retracts. 5. The transverse cylinder moves to the left, and at the same time the second lifting cylinder is lifted; 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 perform reaming operation. After the hole is expanded, the fourth telescopic cylinder resets. 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 releases and the third telescopic cylinder returns to its original position. This completes the assembly of one elbow tube.

[0046] More specifically, the present invention is an elbow pipe assembly machine whose main components include a machine platform, a four-axis robot gripper mechanism, a flexible vibrating plate, a sorting mechanism, an elbow positioning mechanism, a feeding mechanism, a push rod, a transfer mechanism, a reaming rod, a vision system (primarily a vision camera), and an electronic control system. The vision camera takes a picture of the flexible vibrating plate surface to determine the position, size, and opening direction of the envelope, and then guides the four-axis robot gripper mechanism to pick up the envelope.
