[0033] Please refer to Figure 2 The electrode head cache mechanism includes an adjustable stroke slide cylinder 4 and an electrode head cache platform 5. The electrode head cache platform 5 is fixedly connected to the movable slide of the adjustable stroke slide cylinder 4. The electrode head cache platform 5 is provided with a front electrode head cache position 10, a middle electrode head cache position 14 and a rear electrode head cache position 13 from the front to the rear.

[0034] Please refer to Figure 3-5 The adjustable-stroke slide cylinder 4 is connected to the overall structural mounting bracket 1 via four hexagon socket screws. The electrode tip buffer 5 is cut, punched, and polished from a thickened steel block, and its surface is chrome-plated for enhanced aesthetics and wear resistance. It has three electrode tip buffer positions. The front electrode tip buffer position 10 and the middle electrode tip buffer position 14 are combined to buffer the electrode tips of electrofusion pipe fittings with relatively close electrode posts. The front electrode tip buffer position 10 and the rear electrode tip buffer position 13 are combined to buffer the electrode tips of electrofusion pipe fittings with relatively far electrode posts. The electrode tip buffer position 5 is connected to the movable slide of the adjustable-stroke slide cylinder 4 via six hexagon socket screws.

[0035] The electrode tip gripping mechanism includes a 90° rotating cylinder 9, a lifting cylinder 11, and a finger cylinder 12.

The electrode tip stopper 18 is used to limit the pressure during pressing, preventing excessive pressing. The electrode tip measuring and welding end 19 is used for subsequent resistance measurement and on-site welding connection.

[0038] The specific implementation process of the utility model device in the production process is as follows:

[0039] First, adjust the stroke of the adjustable slide cylinder 4 according to the specifications of the electrofusion pipe fittings being assembled and packaged. Then, start the device. The front conveyor mechanism feeds the electrode tips 7 one by one into the direct vibration conveying channel 8. The electrode tip pressing end 17 and the electrode tip stop 18 are located within the direct vibration conveying channel 8, while the electrode tip measurement welding end 19 is exposed for grasping. The direct vibration feeder 3 then starts to convey the electrode tips 7 one by one to the left. When the in-position sensing sensor 6 detects the electrode tip 7, it indicates that the electrode tip 7 has been delivered to its designated position, at which point the direct vibration feeder 3 stops.

[0040] Then the lifting cylinder 11 drives the finger cylinder 12 to move down to its position, and then the finger cylinder 12 drives the electrode head clamps on the left and right sides to close and grab the electrode head 7. Then the lifting cylinder 11 moves up and drives the finger cylinder 12 to clamp the electrode head 7 out of the direct vibration conveying channel 8. At this time, the in-place sensing sensor 6 detects that there is no electrode head, and the direct vibration feeder 3 starts to continue conveying the electrode head to the left until it is sensed by the in-place sensing sensor 6 and stops. At the same time, the 90° rotating cylinder 9 rotates 90° counterclockwise to its position, and the lifting cylinder 11 drives the finger cylinder 12 to move down to insert the electrode head 7 into the front electrode head buffer position 10, and then the finger cylinder 12 drives the electrode head clamps on the left and right sides to loosen and release the electrode head 7. Then the lifting cylinder 11 moves up to its position, the 90° rotating cylinder 9 rotates 90° clockwise, and at the same time the adjustable stroke slide cylinder 4 moves out to drive the electrode head buffer table 5 to move forward. If the electrode head spacing of the assembled and packaged electric fusion pipe fittings is short at this time, the middle electrode head buffer position 14 is moved to the position of the original front electrode head buffer position 10;

[0041] If the electrode head spacing of the assembled and packaged electric fusion pipe fittings is large, the rear electrode head buffer position 13 is moved to the position of the original front electrode head buffer position 10. Then the lifting cylinder 11 drives the finger cylinder 12 to move down to its position, and the finger cylinder 12 drives the electrode head clamps on the left and right sides to close and clamp the newly positioned electrode head, and then the lifting cylinder 11 moves up to its position, and at the same time, the in-position sensing sensor 6 continues to combine with the direct vibration feeder 3 to transport the electrode head. Then the 90° rotating cylinder 9 rotates 90 degrees counterclockwise to its position, and then the lifting cylinder 11 drives the finger cylinder 12 to move down and insert the electrode head into the existing electrode head buffer position. Then the finger cylinder 12 loosens the electrode head clamps on the left and right sides to release the electrode head, and then the lifting cylinder 11 moves up to its position, and the 90° rotating cylinder 9 rotates 90 degrees clockwise to return to its original position. At the same time, the adjustable stroke slide cylinder 4 drives the electrode head buffer platform 5 to move backward and return to its original position until the rear end electrode head grabbing and pressing equipment grabs the two electrode heads at one time to press the electrode heads of the electric fusion pipe fittings. The device then starts the next conveying, grabbing and caching, and the device action is completed.
