Detailed ways

In order for those skilled in the art to further understand the features and technical content of the present invention, please refer to the following detailed description and accompanying drawings of the present invention. 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 degassing and sealing device for continuous parallel transport of heat pipes, comprising: a feeding mechanism 2 and a pressing mechanism 3; 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 that 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 and a pressing mechanism 3 are sequentially arranged on the processing table 20 along the feeding direction 21 . Wherein, the heating unit 22 inputs heat to each traveling pipe material 1 so as to raise the temperature of the working fluid in the pipe material 1 and remove gas. During the heating process, each pipe material 1 can be pushed forward by the feed movement of the rear pipe material 1, and can be pushed to the pressing mechanism 3 when the degassing is completed.

As shown in FIG. 3 and FIG. 4 , after the pipe 1 undergoes the above-mentioned degassing process, the sealing end 10 of the pipe 1 must be pressed and closed. The sealing end 10 of the pipe material 1 protrudes from one 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 located on the top and bottom of the sealing end 10 respectively. Therefore, each pipe 1 can pass through the sealing molds of the pressing mechanism 3 after being degassed by the heating unit 22 on the processing table 20 30 to press and seal the sealing end 10 of the pipe material 1 . At the same time, the sealing mold 30 can be in a high-temperature state when pressing the pipe material 1 , so as to provide the sealing end 10 of the pipe material 1 with thermal compression, so as to make the sealing more tightly and form the 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 degassing and sealing 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 whose operation can be controlled by a pneumatic cylinder 50 . As shown in Figure 5, when the pipes 1 on the processing table 20 are still performing their corresponding processing operations, the 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 part 51 can exit the processing table 20 with all the above-mentioned processed pipes 1 , so that the pipe 1 to be processed enters from the feed end 200 of the processing table 20 . The withdrawn processed pipe material 1 can be transported to the storage place through the receiving plate 6, so as to carry out inspection or other related heat pipe processing operations.

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

As shown in FIGS. 6 and 7 , 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 Figure 7), and each pipe 1 can be fed by the processing table 20 through the push mechanism 7. The end 200 is conveyed towards the discharge end 201, thereby, the purpose of continuously conveying the pipe 1 can also be achieved.

As shown in Figure 8, when the heat pipe degassing and sealing device is provided with a push mechanism 7, the heat pipe forming device can be placed vertically or obliquely (not shown in the figure), and each pipe material 1 can be processed in an upright state. But it is different from the horizontal processing state of the above-mentioned pipe materials 1 .

According to the above-mentioned heat pipe degassing and sealing device, the present invention provides a degassing and sealing method for continuous parallel transport of heat pipes, the steps of which are as follows:

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 be continuously pushed by using the inclined plane and gravity or additional devices that can provide pushing power, such as the pushing mechanism 7, etc.; in the way of using the inclined plane and gravity, each pipe 1 is conveyed and processed in a horizontal state, and when using the pushing power, Each pipe material 1 can be transported and processed in a horizontal, vertical or inclined state.

b) Degassing: During the continuous push and feeding process 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, the nozzles of the degassed pipes 10 are pressed together; and

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

According to the above-mentioned step process, the degassing and sealing method for continuous parallel transportation of heat pipes of the present invention can be obtained.

The degassing and sealing method and device for continuous parallel transport of the heat pipes of the present invention not only do not need to use traditional mechanical claw clamps to clamp the heat pipes, but also can avoid damage to the pipes. At the same time, since the pipes 1 are continuously arranged side by side and are closely connected to each other, they can be continuously pushed by feeding from the rear, so that each pipe can be fed forward, and at the same time, the degassing inside the heat pipe and the sealing and pressing of the pipe mouth are carried out. Processing operations, realize continuous manufacturing of heat pipes, and improve production efficiency.
