The accompanying drawings are provided for reference and illustration only, and are not intended to limit the present invention.

1 and 2 are schematic side and top views of the present invention, respectively. The present invention provides a forming device for continuous parallel conveying of heat pipes, comprising: a feeding mechanism 2, a pressing mechanism 3 and a welding mechanism 4; wherein:

The feeding mechanism 2 has a processing table 20, and the processing table 20 has an input end 200 and an output end 201 which are far away from each other. When the pipe 1 is placed horizontally on the processing table 20, the feeding end 200 can be located at a higher position than the discharging end 201, so that the processing table 20 is placed in an inclined position from high to low. Define a feed direction 21 extending from the feed end 200 towards the discharge end 201 on the processing table 20, so that each pipe material 1 advances along the feed direction 21, because each pipe material 1 is continuously arranged side by side on the processing table 20, and each The pipes 1 are pushed continuously due to the rear feed, so that each pipe 1 can be fed forward.

A heating unit 22 , the pressing mechanism 3 and the welding mechanism 4 are sequentially arranged on the processing table 20 along the feeding direction 21 . Among them, the heating unit 22 inputs heat to each advancing pipe material 1 to heat up and degas the working fluid in the pipe material 1, and each pipe material 1 can be pushed forward by the feeding movement of the rear pipe material 1 during the heating process. , until the degassing is completed, it can be pushed to the pressing mechanism 3.

As shown in Figures 3 and 4, after the pipe material 1 passes through the above-mentioned degassing process, the sealing end 10 of the pipe material 1 must be pressed and closed, and the sealing end 10 of the pipe material 1 protrudes from the side of the processing table 20, so that The pressing mechanism 3 is relatively located at the sealing end 10 of the pipe material 1 . The pressing mechanism 3 has a set of sealing molds 30 respectively located above and below the sealing end 10, so each pipe 1 can pass through the sealing of the pressing mechanism 3 when the degassing is completed after passing through the heating unit 22 on the processing table 20 The mold 30 presses and closes the sealed end 10 of the pipe 1 . At the same time, the sealing mold 30 can be in a high-temperature state when pressing the pipe 1 , providing the sealing end 10 of the pipe 1 with thermal compression, so that the seal is more tightly sealed.

As shown in Figures 5 and 6, after the sealing end 10 of the pipe 1 is sealed by the pressing mechanism 3, it is still pushed forward by the feeding movement of the pipe 1 at the rear, so that the sealed pipe 1 can just be pushed To the welding mechanism 4. The welding mechanism 4 is a spot welder, which performs spot welding on the sealed end 10 of the pipe material 1 to form a sealing structure 11 . In this way, the processing procedures such as degassing and sealing of the heat pipe can be completed.

In addition, the heat pipe forming device may further include a material ejection mechanism 5 . The unwinding mechanism 5 is arranged at the discharge end 201 of the feeding mechanism 1 , and has a material distributing member 51 , and the movement of the material distributing member 51 can be controlled by a pneumatic cylinder 50 . As shown in Figure 7, when the pipes 1 on the processing table 20 are still performing their corresponding processing operations, the material ejection mechanism 5 can resist the discharge end 201 of the processing table 20 through its distribution part 51, so that Each pipe material 1 on the processing table 20 can perform its corresponding processing operation. After the processing of each pipe 1 is completed, the distributing member 51 can exit the processing table 20 for the pipes 1 that have been processed above, and allow the pipes 1 to be processed to enter from the feeding end 200 of the processing table 20 . The processed pipe material 1 that has been withdrawn can be transported to the storage place through a receiving plate 6, so as to carry out inspection or other related heat pipe processing operations.

Composed of the above structure, the forming device for continuous parallel transport of heat pipes of the present invention can be obtained.

As shown in FIGS. 8 and 9 , the processing table 20 of the feeding mechanism 2 can also be placed horizontally, and a pushing mechanism 7 is arranged on the processing table 20 . The pushing mechanism 7 has at least one pulley set 70 pressed against the surface of the pipe 1 and a motor 71 for driving the pulley set 70 . In the embodiment of the present invention, two pulley sets 70 are respectively pressed against the both sides of the surface of the pipe 1 (as shown in FIG. 9 ), and each pipe 1 can be fed by the processing table 20 through the push mechanism 7. End 200 is conveyed towards discharge end 201. Thus, the purpose of continuously conveying the pipe material 1 can also be achieved.

As shown in Figure 10, when the heat pipe forming device is provided with a push mechanism 7, the heat pipe forming device can also be placed vertically or obliquely (not shown in the figure), and each pipe material 1 is processed in an upright state, while It is different from the horizontal processing state of the above-mentioned pipe materials 1 .

a) Feeding: The pipes 1 with built-in capillary tissue 12 and working fluid 13 (as shown in Figure 3) are continuously arranged side by side, and each pipe 1 is continuously pushed to feed; in this step, each pipe 1. It can utilize the inclined plane and gravity to continuously push or additionally set up a device that can provide pushing power, such as the pushing mechanism 7 and the like. In the method of using inclined plane and gravity, each pipe material 1 is transported and processed in a horizontal state, and when using pushing power, each pipe material 1 can be placed in a horizontal, vertical or inclined state.

b) Degassing: In the process of continuous pushing and feeding of each pipe 1, heat is input to each pipe 1 for degassing;

c) Pressing: during the continuous pushing and feeding process of each pipe 1, press the mouth of the pipe 10 that has been degassed;

d) Welding: during the process of continuous pushing and feeding of each pipe material 1, welding is performed on the mouth of the pressed pipe material 10; and

e) Material return: the pipe material 1 that has completed the above steps is withdrawn from processing.

According to the above-mentioned steps, the forming method of the heat pipes of the present invention can be obtained for continuous parallel transportation.
