Detailed Description
The technical contents and the detailed description of the invention are described as follows with the accompanying drawings:
fig. 1 and fig. 2 are schematic top views of a heat pipe continuous conveyor of the present invention. Referring to fig. 1 and 2, the method and apparatus for continuously transferring and welding heat pipes of the present invention mainly transfer the heat pipes 1 in a horizontal continuous conveying manner during manufacturing and production, and simultaneously perform welding and sealing on the heat pipes 1 after being pressed and sealed or shrunk.
The method for continuously conveying and welding the heat pipe comprises the following steps: firstly, placing the heat pipe 1 after being pressed and sealed in an aggregate unit 2, and continuously sending out the heat pipe 1 through a conveying unit 3;
the power generation source to be conveyed by the conveying unit 3 is a power generation unit 31 formed of either a stepping or servo motor. The power generating assembly 31 is driven by a pulse signal output from an external control unit (not shown). The power output by the power generating assembly 31 drives the transmission assembly 32 to rotate through the rotating shaft 311, and the rotating wheel 33 on the transmission assembly 32 drives the conveying belt 34 to move;
since the external control unit outputs the pulse signal at continuous intervals, when the pulse signal drives the power generating assembly 31 each time, the rotating shaft 311 of the power generating assembly 31 is rotated one time, and the movement of the rotating one time forms the conveying unit 3 to convey one heat pipe 1 forward, so that the heat pipe 1 can be accurately positioned in the welding unit 4 (as shown in fig. 3, 4 and 5), and the welding unit 4 is sealed.
As shown in fig. 1 and 2: in the process of continuously conveying, degassing, pressing and sealing the heat pipe, the used device comprises: a conveying unit 3; an aggregate unit 2 disposed at one end of the conveying unit 3; a welding unit 4 arranged at one side of the conveying unit 3 and a collecting unit 5 arranged at the other end of the conveying unit 3; wherein,
the aggregate unit 2 is used for placing the heat pipe 1 to be processed;
the conveying unit 3 has a power generating assembly 31. The power generation assembly 31 is constituted by either a stepping or 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 rotating wheel 33, the rotating wheel 33 is sleeved with a conveying belt 34 driven by the rotating wheel 33, and the conveying belt 34 is provided with a plurality of placing spaces 341 for placing the heat pipes 1 to be processed at intervals;
the welding unit 4 is provided with a gun body 41, the front end of the gun body 41 is a welding end 42, and when the external control unit controls the welding unit 4, the welding end 42 can perform hot melting on the sealing end of the heat pipe 1 after being pressed and sealed;
a collecting unit 5 for collecting the processed heat pipe 1;
when the invention is processed and manufactured, the heat pipe 1 which is pressed and sealed is firstly placed in the aggregate unit 2; when the conveyor belt 34 of the conveyor unit 3 is driven, the heat pipe 1 will automatically fall into the placement space 341 of the conveyor belt 34; when the power generation assembly 31 of the conveying unit 3 is continuously and intermittently output pulse signals by an external control unit, and each time the pulse signals drive the power generation assembly 31, the rotating shaft 311 of the power generation assembly 31 rotates by one cell, and the movement of the rotating cell forms the power for conveying the conveying unit 3 forward by one cell, so that the heat pipes 1 to be processed can be continuously sent out one by one.
When the heat pipe 1 is continuously sent out by the conveyer belt 34, and the heat pipe 1 with the pressed seal is conveyed and positioned at the welding unit 4, the external control unit starts the welding unit 4, and the welding end 42 of the welding unit 4 is thermally fused with the pressed seal of the heat pipe 1 (as shown in fig. 3, 4 and 5).
After the heat pipe 1 is welded and sealed, because the power generating assembly 31 is driven by the pulse signal output by the external control unit, the rotating shaft 31 of the power generating assembly 31 rotates one grid, and the welded and sealed heat pipe 1 is sent away from the welding unit 4, so that the next heat pipe 1 with a pressed seal directly enters the welding unit 4, and the heat pipe 1 with the welded and sealed seal is also sent to the collecting unit 5 to be collected, i.e. the welding and sealing operation after the heat pipe is pressed and sealed is completed.
Fig. 6 is a schematic view of a second embodiment of the present invention. As shown in FIG. 6, the heat pipe continuous conveying and welding method of the present invention can be applied to the welding of the heat pipe 1a after shrinking, in addition to the heat pipe 1 with the pressed seal.
Firstly, placing the heat pipe 1a which is shrunk in an aggregate unit 2, and continuously sending out the heat pipe 1a through a conveying unit 3;
the power generation source to be conveyed by the conveying unit 3 is a power generation unit 31 formed of either a stepping or servo motor. The power generating assembly 31 is driven by a pulse signal outputted from an external control unit (not shown). The power output by the power generating assembly 31 drives the transmission assembly 32 to rotate through the rotating shaft 311, and the rotating wheel 33 on the transmission assembly 32 drives the conveying belt 34 to move.
Because the external control unit outputs the pulse signal in a continuous interval manner, 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 rotation of one grid forms a grid for the conveying unit 3 to convey the heat pipe 1a forwards, so that the heat pipe 1a can be accurately positioned in the welding unit 4, and the welding unit 4 is sealed.
Fig. 7 is a schematic view of a third embodiment of the present invention. As shown in fig. 7: according to the invention, when the conveying unit 3 conveys the heat pipe 1 for a long time, the conveying belt 34 of the conveying unit 3 is fatigue due to materials, and the conveying belt 34 cannot convey the heat pipe 1 and accurately position the heat pipe 1 at the workstation of the welding unit 4 under the driving of the power generation assembly 31, the welding unit 4 is provided with the positioning sensing unit 6, when the positioning sensing unit 6 senses that the heat pipe 1 arrives, a signal is immediately output to the external control unit, the external control unit controls the power generation assembly 31 to stop rotating, and after the heat pipe 1 is welded, the power generation assembly 31 is rotated to convey and position the next heat pipe 1 in the welding unit 4 to weld the next heat pipe 1.
Furthermore, the invention uses the heat pipes which are pressed and sealed to carry out welding and sealing operation, so that the quality, the production speed and the quantity of the heat pipes 1 are improved, the volume of the processing machine is relatively reduced, and the processing machine can be erected according to different production modes.
The above description is only for the preferred embodiment of the present invention and is not intended to limit the scope of the present invention, and all equivalent structural changes made by using the contents of the present specification and the drawings, or any other related technical fields, are intended to be covered by the present invention.
