Detailed ways

Relevant technical content and detailed description of the present invention, now cooperate accompanying drawing to explain as follows:

FIG. 1 and FIG. 2 are schematic diagrams of the heat pipe continuous conveying machine and its top view of the present invention. As shown in Fig. 1 and Fig. 2, the method and device for continuous transfer and welding of heat pipes of the present invention are mainly to transfer the heat pipe 1 in a horizontal continuous transfer mode during production, and simultaneously press and seal the heat pipe 1 during the transfer process. Or the heat pipe 1 after shrinkage is welded and sealed.

The above-mentioned heat pipe continuous transfer welding method includes: firstly, placing the heat pipe 1 after pressing and sealing in the collecting unit 2, and continuously sending the heat pipe 1 out through the conveying unit 3;

The power generating source conveyed by the conveying unit 3 is a power generating assembly 31 formed by any one of a stepper motor or a servo motor. The power generating assembly 31 is driven by a pulse signal output by an external control unit (not shown in the figure). The power output by the power generation component 31 drives the transmission component 32 to rotate through the rotating shaft 311, and at the same time, the runner 33 on the transmission component 32 drives the conveyor belt 34 to move;

Since the external control unit outputs pulse signals at continuous intervals, when each pulse signal drives the power generation assembly 31, the rotating shaft 311 of the power generation assembly 31 is rotated by one grid, and the movement of the one grid rotation forms the forward transport of the conveying unit 3. A heat pipe 1 allows the heat pipe 1 to be accurately positioned in the welding unit 4 (as shown in Figure 3, Figure 4, and Figure 5), allowing the welding unit 4 to be sealed.

As shown in Fig. 1 and Fig. 2: in the heat pipe continuous transmission degassing and sealing process of the present invention, the device used includes: a conveying unit 3; a material collecting unit 2 arranged at one end of the conveying unit 3; The welding unit 4 on one side and the collecting unit 5 arranged at the other end of the conveying unit 3; wherein,

A material collecting unit 2 is used to place the heat pipe 1 to be processed;

The conveying unit 3 has a power generation assembly 31 . The power generating unit 31 is constituted by either a stepping motor or a servo motor. The rotating shaft 311 of the power generating assembly 31 is connected with a transmission assembly 32, the transmission assembly 32 is provided with a runner 33, the runner 33 is provided with a conveyor belt 34 driven by the runner 33, and the conveyor belt 34 is provided with a plurality of Spaces 341 for placing heat pipes 1 to be processed at intervals;

The welding unit 4 has a gun body 41 on it, and the front end of the gun body 41 is a welding end 42. When the external control unit controls the welding unit 4, the welding end 42 can be made to heat-melt the sealing end of the heat pipe 1 after pressing and sealing. ;

A collection unit 5, used to collect the processed heat pipe 1;

When the present invention is being processed and manufactured, the heat pipe 1 that has been pressed and sealed is placed in the collection unit 2; when the conveyor belt 34 of the conveying unit 3 is driven, the heat pipe 1 will automatically fall into the placement space 341 of the conveyor belt 34 In the middle; the power generation component 31 of the delivery unit 3 is output by the external control unit in a continuous interval mode. The movement forms the power of the conveying unit 3 to convey one grid forward, and can continuously send out the heat pipes 1 to be processed one by one.

When the heat pipe 1 is sent out continuously by the conveyer belt 34, and the heat pipe 1 after pressing and sealing is transported and positioned on the welding unit 4, the external control unit starts the welding unit 4, and at this moment, the welding end 42 of the welding unit 4 is connected to the heat pipe 1. Hot-melt the press-fit seal (as shown in Figure 3, Figure 4, and Figure 5).

After the heat pipe 1 is welded and sealed, because the power generation component 31 is driven by the pulse signal output by the external control unit, the rotating shaft 31 of the power generation component 31 rotates one more step, and the heat pipe 1 that has been welded and sealed is sent away from the welding unit 4 , let the next heat pipe 1 that has been pressed and sealed directly enter the welding unit 4, and the heat pipe 1 that has also been welded and sealed will be transported to the collection unit 5 for collection, that is, the welding and sealing operation after the heat pipe is pressed and sealed is completed .

Fig. 6 is a schematic diagram of the second embodiment of the present invention. As shown in FIG. 6 , the heat pipe continuous conveying welding method of the present invention can not only be applied to the heat pipe 1 that has been pressed and sealed, but also can be applied to the welding of the heat pipe 1a after shrinkage.

First, place the heat pipe 1a after shrinkage in the collection unit 2, and send the heat pipe 1a continuously through the delivery unit 3;

The power generating source conveyed by the conveying unit 3 is a power generating assembly 31 formed by any one of a stepper motor or a servo motor. The power generation assembly 31 is driven by a pulse signal output by an external control unit (not shown in the figure). The power output by the power generation component 31 drives the transmission component 32 to rotate through the rotating shaft 311 , and at the same time, the runner 33 on the transmission component 32 drives the conveyor belt 34 to move.

Since the external control unit outputs pulse signals at continuous intervals, each time the pulse signal drives the power generation assembly 31, the rotating shaft 311 of the power generation assembly 31 is rotated by one grid, and the movement of the one grid rotation forms the transport unit 3 to transport the heat pipe forward. 1a advances one grid, so that the heat pipe 1a can be accurately positioned in the welding unit 4, so that the welding unit 4 can be sealed.

Fig. 7 is a schematic diagram of a third embodiment of the present invention. As shown in Figure 7: the present invention considers that when the conveying unit 3 transports the heat pipe 1 for a long time, the conveying belt 34 of the conveying unit 3 will be fatigued due to the material, and the conveying belt 34 cannot convey the heat pipe 1 under the drive of the power generation assembly 31 When accurately positioned on the workstation of the welding unit 4, the present invention is provided with a positioning sensing unit 6 on the welding unit 4, and when the positioning sensing unit 6 senses the arrival of the heat pipe 1, it immediately outputs a signal to the external control unit, by The external control unit controls the power generation assembly 31 to stop rotating. After the heat pipe 1 is welded, the power generation assembly 31 is rotated to transport and position the next heat pipe 1 in the welding unit 4 for welding of the next heat pipe 1 .

Further, the present invention uses the heat pipes that have been pressed and sealed to be welded and sealed continuously, so that the quality, production speed and quantity of the heat pipes 1 are improved, and the size of the processing machine is relatively reduced, and the processing machine can be set up according to different production modes.

The above is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made by using the description of the present invention and the contents of the accompanying drawings, or directly or indirectly used in other related technical fields, All are included in the patent scope of the present invention in the same way.
