Description

Technical Field

[0001] The utility model relates to the technical field of heat pipe production equipment, in particular to an automatic loading and unloading device for evacuating a heat pipe. Background Art

[0002] During the production process of the heat pipe, evacuation is required. In order to evacuate the heat pipe, a vacuum tube for evacuation is often reserved, and the inside of the heat pipe is evacuated through the vacuum tube. When evacuating the heat pipe, manual loading and unloading is often used, which requires a large amount of labor and slow production efficiency. The existing automatic loading and unloading device only clamps the heat pipe and does not fix the vacuum tube. However, the diameter of the vacuum tube is small and the length is long, and it is a slender pipe fitting. During the feeding process, the vacuum tube is prone to swing and is difficult to insert into the evacuation device. Especially when the clamped heat pipe is skewed, the vacuum tube is severely offset, easily hitting the evacuation device, resulting in bending and damage of the vacuum tube, causing the entire heat pipe to be scrapped, with poor reliability and stability, high production cost, and low yield. Therefore, it is necessary to improve. Summary of the Utility Model

[0031] Specifically, as Figure 4 shown, the upper clamping assembly 42 includes a two-jaw cylinder 422 and two upper clamping blocks 421. The two upper clamping blocks 421 are respectively arranged on the two jaws of the two-jaw cylinder 422. The lower clamping assembly 43 includes a four-jaw cylinder 433, two first lower clamping blocks 431 and two second lower clamping blocks 432. The two first lower clamping blocks 431 are respectively arranged on the upper and lower jaws of the four-jaw cylinder 433, and the two second lower clamping blocks 432 are respectively arranged on the left and right jaws of the four-jaw cylinder 433.
