Description

Technical Field

[0001] The present invention relates to the technical field of heat pipe production equipment, and particularly relates to a welding device for the reduced head end of a heat pipe. Background Art

[0002] In the production process of heat pipes, for the welding of the reduced head end of a heat pipe, generally, the heat pipe is manually loaded and placed in a welding device, and a welding torch in the welding device is used to perform spot welding on the reduced head end of the heat pipe. Subsequently, it is manually taken out and collected and placed. Due to reasons such as the storage environment and manual grasping by workers, an oxide layer may exist on the reduced head end of the heat pipe before spot welding. During spot welding, the oxide layer of the heat pipe is easily wrapped into the welding structure, resulting in poor welding effects, easy occurrence of cracks, easy generation of defective products, and low production efficiency, which is not convenient for production applications. Summary of the Invention

For this purpose, the present invention provides a welding device for the reduced head end of a heat pipe. The heat pipe is loaded and transported through a loading mechanism and a conveying mechanism. The reduced head end of the heat pipe extends into a heating chamber of a heating mechanism. By filling a reducing gas and an inert gas into the heating chamber and using a heating element to heat the reduced head end of the heat pipe, it is beneficial to remove the oxide layer on the reduced head end of the heat pipe before welding, improve the welding effect, increase the yield rate, and facilitate production applications.

[0004] According to the welding device for the reduced head end of a heat pipe described in an embodiment of the present invention, it includes a frame and a loading mechanism, a conveying mechanism, a heating mechanism, and a welding mechanism connected to the frame. A first hopper and a rack assembly are provided on the frame. The first hopper has a receiving cavity for placing the heat pipe.

The loading mechanism can load the heat pipe in the receiving cavity onto the loading station of the rack assembly. The conveying mechanism can convey the heat pipe on the rack assembly in the order of the loading station, the heating station, the welding station, and the discharging station. The heating mechanism is arranged corresponding to the heating station. The heating mechanism has a heating chamber for the reduced head end of the heat pipe to extend into. A heating element is provided in the heating chamber. A reducing gas and an inert gas can be filled into the heating chamber. The heating element can heat the reduced head end of the heat pipe.

The feeding mechanism feeds the heat pipe in the accommodating cavity to the feeding station of the rack assembly. The conveying mechanism conveys the heat pipe at the feeding station to the heating station. The shrinkage end of the heat pipe extends into the heating chamber of the heating mechanism. By filling the heating chamber with a reducing gas and an inert gas and making the heating element heat the shrinkage end of the heat pipe, the reducing gas is used to reduce the oxide layer on the shrinkage end of the heat pipe to remove the oxide layer on the shrinkage end of the heat pipe, and the inert gas is used to protect the shrinkage end of the heat pipe to avoid the generation of an oxide layer. Subsequently, the conveying mechanism conveys the heat pipe at the heating station to the welding station, and the welding mechanism welds the shrinkage end of the heat pipe at the welding station.

Feeding and conveying the heat pipe through the feeding mechanism and the conveying mechanism is beneficial to improving production efficiency and can reduce the contact of workers with the heat pipe, reducing the possibility of the heat pipe generating an oxide layer due to grease, sweat, etc. on human hands. Removing the oxide layer on the shrinkage end of the heat pipe before welding through the heating mechanism is beneficial to improving the welding effect, increasing the yield rate, and facilitating production application.

[0037] Referring to Figure 1 、 Figure 2 and Figure 3 , a welding device for the shrinkage head end of a heat pipe, which includes a frame 100 and a feeding mechanism 200, a conveying mechanism 300, a heating mechanism 400 and a welding mechanism 500 connected to the frame 100. A first hopper 110 and a rack assembly 120 are provided on the frame 100. The first hopper 110 has a receiving cavity 101 for placing the heat pipe 1, and the rack assembly 120 has a feeding station 102, a heating station 104, a welding station 105 and a discharging station 106. The feeding mechanism 200 can feed the heat pipe 1 in the receiving cavity 101 to the feeding station 102 of the rack assembly 120. The conveying mechanism 300 can convey the heat pipe 1 on the rack assembly 120 in the order of the feeding station 102, the heating station 104, the welding station 105, and the discharging station 106. The heating mechanism 400 is arranged corresponding to the heating station 104. The heating mechanism 400 has a heating chamber 410 into which the shrinkage head end of the heat pipe 1 extends. A heating element (not shown in the figure) is provided in the heating chamber 410. A reducing gas and an inert gas can be filled into the heating chamber 410, and the heating element can heat the shrinkage head end of the heat pipe 1. The welding mechanism 500 is arranged corresponding to the welding station 105, and the welding mechanism 500 can weld the shrinkage head end of the heat pipe 1 located at the welding station 105.

[0038] It can be understood that, such as Figure 1 、 Figure 2 and Figure 3As shown in the figure, the first hopper 110 is located on the left side of the rack assembly 120. The rack assembly 120 is sequentially provided with a loading station 102, a heating station 104, a welding station 105, and a unloading station 106 in the direction from left to right. The conveying mechanism 300 conveys the heat pipe 1 from left to right. During use, the heat pipe 1 is placed in the accommodating cavity 101 of the first hopper 110. The loading mechanism 200 loads the heat pipe 1 in the accommodating cavity 101 to the loading station 102 of the rack assembly 120. The conveying mechanism 300 conveys the heat pipe 1 located at the loading station 102 to the heating station 104. The shrinking end of the heat pipe 1 extends into the heating chamber 410 of the heating mechanism 400. The heating mechanism 400 is connected to a gas supply device. By filling a reducing gas and an inert gas into the heating chamber 410 and making the heating element heat the shrinking end of the heat pipe 1, the reducing gas is used to reduce the oxide layer at the shrinking end of the heat pipe 1 to remove the oxide layer at the shrinking end of the heat pipe 1, and the inert gas is used to protect the shrinking end of the heat pipe 1 to avoid the formation of an oxide layer. Subsequently, the conveying mechanism 300 conveys the heat pipe 1 located at the heating station 104 to the welding station 105, and the welding mechanism 500 welds the shrinking end of the heat pipe 1 located at the welding station 105. After welding is completed, the conveying mechanism 300 conveys the heat pipe 1 located at the welding station 105 to the unloading station 106 for unloading. By loading and conveying the heat pipe 1 through the loading mechanism 200 and the conveying mechanism 300, it is beneficial to improve production efficiency and reduce the contact of workers with the heat pipe 1, reducing the possibility of the heat pipe 1 generating an oxide layer due to grease, sweat, etc. on human hands. By removing the oxide layer at the shrinking end of the heat pipe 1 through the heating mechanism 400 before welding, it is beneficial to improve the welding effect, increase the yield rate, and facilitate production application.

[0039] During actual application, the specific structures of the loading mechanism 200, the conveying mechanism 300, the heating mechanism 400, the welding mechanism 500, etc. can be set accordingly according to actual usage needs, and will not be described in detail here. Specific descriptions will be given below.

[0040] In some embodiments, the loading mechanism 200 includes a first driver 210 and a top plate 220 drivingly connected to the first driver 210. The top plate 220 is slidably connected to the frame 100 and can move up and down and extend into the accommodating cavity 101. A pushing portion 221 is provided on the top plate 220, and a clamping inclined surface 222 is provided on the pushing portion 221. A matching plate 111 is provided on one side of the first hopper 110 with respect to the top plate 220. The clamping inclined surface 222 is located on the side of the pushing portion 221 close to the matching plate 111 and slopes downward to form an included angle position 201 for accommodating the heat pipe 1 with the matching plate 111. The bottom wall of the accommodating cavity 101 is an inclined surface structure inclined towards the top plate 220, so that the heat pipe 1 in the accommodating cavity 101 can roll to the included angle position 201. The upper end of the matching plate 111 is provided with a first guiding surface 112 inclined towards the loading station 102 of the rack assembly 120.

[0041] It is understandable that, as Figure 1 , Figure 4 , Figure 5 and Figure 6 shown, the top plate 220 is slidably connected to the frame 100 and can be driven by the first driver 210 to move up and down and extend into the accommodating cavity 101. The top plate 220 is located on the right side of the accommodating cavity 101. The bottom wall of the accommodating cavity 101 is inclined towards the lower right side. The mating plate 111 is correspondingly located on the right side of the accommodating cavity 101 and on the right side of the top plate 220. A clamping inclined surface 222 is provided on the upper right side of the top pushing portion 221. The clamping inclined surface 222 is inclined towards the lower right side to form an included angle position 201 with the mating plate 111. A first guiding surface 112 is provided on the upper right side of the mating plate 111. The first guiding surface 112 is inclined towards the loading station 102 of the material rack assembly 120.

[0042] During use, the first driver 210 drives the top plate 220 to move downward, so that the included angle position 201 is located at the bottom wall of the accommodating cavity 101. The heat pipe 1 rolls down along the guide of the bottom wall of the accommodating cavity 101 to the included angle position 201. The clamping inclined surface 222 and the left side wall of the mating plate 111 clamp the heat pipe 1. Subsequently, the first driver 210 drives the top plate 220 to move upward, and uses the top pushing portion 221 to push the heat pipe 1 falling into the included angle position 201 to move upward. When moving to the upper part of the mating plate 111, the heat pipe 1 loses the restriction of the left side wall of the mating plate 111 and rolls to the right side. Guided by the first guiding surface 112, the heat pipe 1 rolls to the loading station 102 to complete the loading of the heat pipe 1. Its structure is simple and it is convenient to realize the one-by-one loading of the heat pipe 1.

[0043] Furthermore, the mating plate 111 is provided with a protruding portion 115 on the side wall close to the top plate 220. During the upward movement of the heat pipe 1 falling into the included angle position 201, the protruding portion 115 is used to squeeze the stacked heat pipes 1 in the included angle position 201, and the redundant stacked heat pipes 1 can be extruded from the included angle position 201, which is beneficial to ensuring the one-by-one loading of the heat pipe 1.

[0044] In practical applications, in addition to the above structure, the heat pipe 1 can also be grabbed for loading and conveying by means of pattern recognition and clamping, or a fixture can be set up to arrange the heat pipes 1 on the fixture, and the heat pipe 1 is grabbed by a mechanical gripper or a suction cup, and then the heat pipe 1 is conveyed to the loading position by a multi-axis manipulator, which can be specifically set according to actual use needs.

[0045] In some embodiments, the first hopper 110 is provided with a limiting plate 113. The limiting plate 113 is located in the accommodating cavity 101 and is perpendicular to the mating plate 111. The limiting plate 113 can move in a horizontal direction parallel to the mating plate 111.

[0046] It is understandable that, as Figure 1 and Figure 4As shown, the limiting plate 113 is located in the accommodating cavity 101 and is arranged perpendicular to the mating plate 111. The first hopper 110 is provided with a guiding column 114. The guiding column 114 is parallel to the front-rear direction and penetrates through the limiting plate 113, so that the limiting plate 113 can move in the horizontal direction parallel to the mating plate 111, thereby changing the front-rear width dimension of the accommodating cavity 101 according to heat pipes 1 of different lengths, improving applicability, restricting the heat pipes 1 to be placed in the accommodating cavity 101 parallel to the front-rear direction, and facilitating their rolling down along the bottom wall of the accommodating cavity 101 to the included angle position 201 for convenient use.

[0047] In actual application, in addition to the above structure, the limiting plate 113 can also be slidably connected to the first hopper 110 through a slide rail to realize its front-rear movement parallel to the mating plate 111, and the specific structure of the limiting plate 113 can be set accordingly according to actual use requirements.

[0048] In some embodiments, the rack assembly 120 is respectively provided with a first baffle 131 and a first pushing member 132 on the front and rear sides of the loading station 102. The first pushing member 132 is connected to a second driver 133, and the second driver 133 can drive the first pushing member 132 to move back and forth, so that the first pushing member 132 can push the heat pipe 1 at the loading station 102 to move until it abuts against the first baffle 131.

[0049] It can be understood that, as Figure 1 and Figure 3 shown, the rack assembly 120 is provided with a first pushing member 132 on the front side of the loading station 102 and a first baffle 131 on the rear side of the loading station 102. During use, the second driver 133 is used to drive the first pushing member 132 to move back and forth, so that the first pushing member 132 pushes the heat pipe 1 at the loading station 102 to move until it abuts against the first baffle 131, thereby realizing the alignment and positioning of the heat pipe 1, facilitating the adjustment of the placement of the heat pipe 1, and facilitating subsequent conveying and use.

[0050] In actual application, the first baffle 131 can also be arranged on the front side of the loading station 102, then the first pushing member 132 is correspondingly arranged on the rear side of the loading station 102, and the specific structures of the first baffle 131 and the first pushing member 132 can be set accordingly according to actual use requirements.

[0051] In some embodiments, the rack assembly 120 includes two first placement racks 121. The two first placement racks 121 are arranged at intervals in the front-rear direction and are parallelly distributed. Each first placement rack 121 is correspondingly provided with a first accommodating groove 122 for placing the heat pipe 1 at the loading station 102, the heating station 104, and the welding station 105, and the front-rear interval distance between the two first placement racks 121 is adjustable.

[0052] It can be understood that, as Figure 1 andFigure 3 As shown, two first material racks 121 are arranged at intervals in the front-rear direction and distributed in parallel. Each first material rack 121 is correspondingly provided with a first receiving groove 122 for placing the heat pipe 1 at the loading station 102, the heating station 104, and the welding station 105, so that the heat pipe 1 can be better placed at the corresponding stations. Both first material racks 121 are slidably connected to the machine frame 100, so that the front-rear interval distance between them can be adjusted, facilitating the adjustment of the position of the material rack assembly 120 and enabling it to adapt to heat pipes 1 of different lengths, improving applicability.

[0053] In actual application, in addition to the above structure, the material rack assembly 120 can also be an integral frame body. Among the two first material racks 121, one can be slidably connected to the machine frame 100 while the other is fixedly arranged on the machine frame 100. Or, multiple installation positions can be set on the machine frame 100, and the first material rack 121 is installed at different installation positions to adjust the front-rear interval distance between the two first material racks 121, which can be specifically set according to actual usage needs.

[0054] In some embodiments, a transfer station 103 is further provided between the loading station 102 and the heating station 104 of the material rack assembly 120. The first material rack 121 is provided with multiple first receiving grooves 122 at the transfer station 103, the heating station 104, and the welding station 105. The conveying mechanism 300 can convey the heat pipes 1 at the loading station 102 to the transfer station 103 one by one. The conveying mechanism 300 can convey multiple heat pipes 1 at the transfer station 103 to the heating station 104 together. The conveying mechanism 300 can convey multiple heat pipes 1 at the heating station 104 to the welding station 105 together.

[0055] It can be understood that as Figure 1 、 Figure 2 and Figure 3As shown, a transfer station 103 is also provided between the loading station 102 and the heating station 104. The loading station 102, the transfer station 103, the heating station 104, the welding station 105, and the unloading station 106 are arranged in sequence in the left-to-right direction. A first placement has a first accommodation groove 122 at the loading station 102, and multiple first accommodation grooves 122 are provided at the transfer station 103, the heating station 104, and the welding station 105. In use, the feeding mechanism 200 feeds the heat pipes 1 one by one to the loading station 102, and the positioning and placement of the heat pipes 1 are realized through the first accommodation grooves 122. The conveying mechanism 300 conveys the heat pipes 1 at the loading station 102 to the transfer station 103 one by one, and then conveys multiple heat pipes 1 at the transfer station 103 to the heating station 104 together. After the oxide layer removal treatment, multiple heat pipes 1 at the heating station 104 are then conveyed to the welding station 105 together, which is conducive to realizing the simultaneous processing of multiple heat pipes 1 and facilitating the improvement of production efficiency. In actual application, in addition to the above structure, the heat pipes 1 can also be grabbed and sent to different stations for processing one by one. The transfer station 103 can be specifically set according to actual use needs.

[0056] In some embodiments, the conveying mechanism 300 includes a moving seat 310 and a lifting seat 320. There are multiple moving seats 310, and they are all slidably connected to the frame 100. The multiple moving seats 310 are arranged in sequence along the conveying direction of the heat pipe 1. Each moving seat 310 is connected to a horizontal driver 330, and the horizontal driver 330 can drive the moving seat 310 to move left and right. A vertical driver 340 is provided on each moving seat 310. There are multiple lifting seats 320 corresponding to the moving seats 310 and they are respectively connected to the multiple vertical drivers 340 one by one. The vertical driver 340 can drive the lifting seat 320 to move up and down. A second placement rack 321 is provided on each lifting seat 320, and multiple second accommodation grooves 322 for placing the heat pipes 1 are correspondingly provided on each second placement rack 321.

[0057] It can be understood that, such as Figure 1 and Figure 7As shown in the figure, three moving seats 310 are provided and are all slidably connected to the frame 100. The three moving seats 310 are arranged in sequence along the conveying direction of the heat pipe 1. Each moving seat 310 is connected with a horizontal driver 330. A vertical driver 340 is provided on each moving seat 310. Three lifting seats 320 are correspondingly arranged and are respectively connected to the three vertical drivers 340 one by one. A second material placing rack 321 is arranged on each lifting seat 320, and a plurality of second accommodating grooves 322 are correspondingly arranged on the second material placing rack 321. During use, a part of the heat pipe 1 is placed in the first accommodating groove 122 for positioning. The horizontal driver 330 drives the corresponding moving seat 310 to move left and right to the corresponding working position. The vertical driver 340 drives the corresponding lifting seat 320 to move upward and drives the second material placing rack 321 thereon to move upward, so that a part of the heat pipe 1 is placed in the second accommodating groove 322. Continuing to move upward, the heat pipe 1 is pushed upward to the upper part of the corresponding working position. Subsequently, the horizontal driver 330 drives the corresponding moving seat 310 to move left and right to convey the heat pipe 1 to the upper part of other working positions. The vertical driver 340 drives the corresponding lifting seat 320 to move downward, driving the second material placing rack 321 to move downward, conveying the heat pipe 1 to the corresponding working position, and placing a part of the heat pipe 1 in the first accommodating groove 122 for positioning. Multiple moving seats 310 can act simultaneously. For example, when the moving seat 310 on the left moves, the moving seats 310 in the middle or on the right can also act. By providing multiple moving seats 310 and lifting seats 320, it is beneficial to improve the transportation efficiency. The above structure is simple and reasonable, facilitating the placement, processing and transportation of the heat pipe 1 and being easy to use.

[0058] In practical applications, in addition to the above structure, the conveying mechanism 300 may further include a plurality of clamping jaws. The heat pipe 1 is clamped by the clamping jaws to realize the grasping of the heat pipe 1, and the clamping jaws are driven to move by a multi-axis moving platform, so as to realize the conveying of the heat pipe 1, which can be specifically set according to actual usage requirements.

[0059] In some embodiments, the first material placing rack 121 is provided with a second guiding surface 123 at the blanking station 106. A second hopper 140 is provided on the frame 100. The conveying mechanism 300 can convey the heat pipe 1 onto the second guiding surface 123, and the second guiding surface 123 can guide the heat pipe 1 into the second hopper 140.

[0060] It can be understood that, such as Figure 3As shown in the figure, the blanking station 106 is arranged on the right side of the first material placing rack 121. A second guiding surface 123 is correspondingly arranged on the right side of the first material placing rack 121. The second hopper 140 is located on the right side of the material rack assembly 120 and below the second guiding surface 123. The second guiding surface 123 slopes downward to the right. During use, the vertical driver 340 drives the lifting seat 320 to move upward, driving the second material placing rack 321 to move upward. The heat pipe 1 at the welding station 105 is lifted by the second material placing rack 321, so that the heat pipe 1 after welding is separated from the welding station 105. The horizontal driver 330 drives the moving seat 310 to move to the right, conveying the heat pipe 1 to above the blanking station 106. Subsequently, the vertical driver 340 drives the lifting seat 320 to move downward, placing the heat pipe 1 on the second guiding surface 123. The heat pipe 1 is guided by the second guiding surface 123 and rolls down to the second hopper 140 for collection. Its structure is simple and reasonable, facilitating the blanking and collection of the heat pipe 1 after processing and facilitating use.

[0061] In practical applications, in addition to the above structure, when the conveying mechanism 300 conveys the heat pipe 1 in a clamping manner, the second hopper 140 can also be directly arranged at the blanking station 106, so that the conveying mechanism 300 can directly convey and place the heat pipe 1 into the second hopper 140. The second guiding surface 123 can be specifically set according to actual use needs, as long as it can guide the heat pipe 1 into the second hopper 140. The specific structure of the second hopper 140 can also be set according to actual use needs.

[0062] In some embodiments, the frame 100 is connected with a third driver 151. The third driver 151 is connected with a positioning block 152 and can drive the positioning block 152 to move up and down. The positioning block 152 can move to abut against the heat pipe 1 at the heating station 104. The heating mechanism 400 is slidably connected to the frame 100. A fourth driver 153 connected to the heating mechanism 400 is arranged on the frame 100. The fourth driver 153 can drive the heating mechanism 400 to move back and forth, so that the shrinking end of the heat pipe 1 at the heating station 104 can extend into the heating chamber 410.

[0063] It can be understood that, such as Figure 1 、 Figure 2 and Figure 3As shown in the figure, the third driver 151 is located above the heating station 104. The heating mechanism 400 is slidably connected to the frame 100 and can move back and forth relatively. During use, the heat pipe 1 is transported to the heating station 104. The third driver 151 drives the positioning block 152 to move downward, so that the positioning block 152 moves to abut against the heat pipe 1 at the heating station 104, thereby restricting the position of the heat pipe 1 and realizing its positioning and fixing. Subsequently, the fourth driver 153 drives the heating mechanism 400 to move forward, so that the shrinking end of the heat pipe 1 located at the heating station 104 can extend into the heating chamber 410. By filling the heating chamber 410 with reducing gas and inert gas and heating the shrinking end of the heat pipe 1 with the heating element, it is beneficial to remove the oxide layer at the shrinking end of the heat pipe 1. After processing, the fourth driver 153 drives the heating mechanism 400 to move backward and reset, and the third driver 151 drives the positioning block 152 to move upward and reset, which is convenient for the subsequent transportation of the heat pipe 1. The above structure is simple and reasonable and convenient to use.

[0064] Specifically, the heating mechanism 400 can be set as a high-frequency induction heating machine, and the heating element is an induction coil. By using a large current of high frequency to flow through the induction coil, a powerful magnetic flux with instantaneous polarity change is generated inside the induction coil. When the shrinking end of the heat pipe 1 is placed inside the induction coil, the magnetic flux will penetrate the shrinking end of the heat pipe 1, and a corresponding powerful eddy current will be generated inside the shrinking end. Utilizing the resistance existing in the metal, Joule heat energy is generated, so that the temperature of the shrinking end of the heat pipe 1 rises rapidly, thereby achieving the purpose of heat treatment. Its heating speed is fast, which is beneficial to reducing the oxide layer and is convenient to use.

[0065] In actual application, in addition to the above structure, a feeding mechanism can also be set. The feeding mechanism uses a mechanical gripper to grip the heat pipe 1 at the heating station 104 and moves and transports the heat pipe 1 towards the heating mechanism 400, so that the shrinking end of the heat pipe 1 located at the heating station 104 can extend into the heating chamber 410; the heating element can also be an electric heating element, etc., which can be specifically set according to actual use needs. Since the specific composition and heating principle of the high-frequency induction heating machine in the embodiment of the present invention are known to those of ordinary skill in the art, they will not be described in detail here.

[0066] In some embodiments, a fifth driver 161 and a sixth driver 162 are respectively provided on the front and rear sides of the rack assembly 120 at the welding station 105. The fifth driver 161 is connected to a second pushing member 163 and can drive the second pushing member 163 to move back and forth. The sixth driver 162 and the welding mechanism 500 are on the same side of the rack assembly 120. The sixth driver 162 is connected to a second baffle 164 and can drive the second baffle 164 to move up and down. The second pushing member 163 can push the heat pipe 1 at the welding station 105 to move until it abuts against the second baffle 164. The welding mechanism 500 includes a seventh driver 510, a connecting seat 520, a gun seat assembly 530, and a welding gun (not shown in the figure). The seventh driver 510 and the gun seat assembly 530 are both arranged on the frame 100. The seventh driver 510 is connected to the connecting seat 520 and can drive the connecting seat 520 to move up and down. An eighth driver 521 is provided on the connecting seat 520. The eighth driver 521 is connected to a roller 522 and can drive the roller 522 to rotate. The roller 522 can move to abut against the heat pipe 1 at the welding station 105 and can drive the heat pipe 1 to rotate. The welding gun is connected to the gun seat assembly 530 and can weld the reduced head end of the heat pipe 1 at the welding station 105.

[0067] It is understandable that, such as Figure 1 , Figure 2 , Figure 3 and Figure 8As shown in the figure, a fifth driver 161 is provided on the front side of the welding station 105 of the rack assembly 120, and a sixth driver 162 is provided on the rear side of the welding station 105. The welding mechanism 500 is located on the rear side of the rack assembly 120. The fifth driver 161 is drivingly connected to a second pushing member 163, and the sixth driver 162 is drivingly connected to a second baffle 164. A seventh driver 510 is located above the welding station 105. The seventh driver 510 is drivingly connected to a connecting seat 520. An eighth driver 521 is provided on the connecting seat 520. The eighth driver 521 is drivingly connected to a roller 522. The gun seat assembly 530 is arranged behind the welding station 105, and a welding gun (not shown in the figure) is connected to the gun seat assembly 530. During use, the sixth driver 162 is used to drive the second baffle 164 to move upward so that the second baffle 164 is located on the rear side of the welding station 105. The fifth driver 161 is used to drive the second pushing member 163 to move back and forth so that the second pushing member 163 pushes the heat pipe 1 at the welding station 105 to move until it abuts against the second baffle 164, thereby realizing the alignment and positioning of the heat pipe 1, facilitating the adjustment of the placement of the heat pipe 1, and facilitating subsequent welding use. Subsequently, the fifth driver 161 drives the second pushing member 163 to move back to its original position, and the sixth driver 162 drives the second baffle 164 to move back to its original position to avoid the welding mechanism 500. The seventh driver 510 drives the connecting seat 520 to move downward, driving the eighth driver 521 and the roller 522 to move downward so that the roller 522 moves to abut against the heat pipe 1 at the welding station 105. The eighth driver 521 drives the roller 522 to rotate, and the heat pipe 1 is driven to rotate by the frictional force. From the perspective of relative motion, it can be regarded as the welding gun rotating relative to the shrinking end of the heat pipe 1. The welding gun welds the shrinking end of the heat pipe 1 to better weld and seal the shrinking end of the heat pipe 1 and achieve a better welding effect.

[0068] In practical applications, the specific structures of the gun seat assembly 530 and the welding gun can be set accordingly according to actual usage requirements. Since the specific composition of the welding gun in the embodiments of the present invention is known to those of ordinary skill in the art, it will not be described in detail here.

[0069] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those of ordinary skill in the art.
