[0066] like Figures 1 to 9As shown, a first aspect of the present invention provides a finned tube insertion device, including a frame 100, a fin assembly, a guide rod assembly 104, a heat exchange tube assembly 106, a first driving device 108, and a second driving device 110; wherein, the fin assembly is placed on the frame 100, and the fin assembly is provided with a plurality of insertion holes, and at least one insertion hole is provided with a picking rod 102 suitable for supporting the fin assembly; the guide rod assembly 104 is positioned on one side of the fin assembly along the axial direction of the insertion holes and corresponds one-to-one with the plurality of insertion holes; the heat exchange tube assembly 106 is positioned along the axial direction of the insertion holes; the guide rod assembly 104 is positioned on one side of the fin assembly along the axial direction of the insertion holes and corresponds one-to-one with the plurality of insertion holes; the heat exchange tube assembly 106 is positioned along the axial direction of the insertion holes; the guide rod assembly 104 is positioned on one side of the fin assembly along the axial direction of the insertion holes; the heat exchange tube assembly 106 is positioned on one side of the finned assembly along the axial direction of the insertion holes; the guide rod assembly 104 ... The axial direction of the tube insertion hole is located on the opposite side of the fin assembly and the guide rod assembly 104, and the heat exchange tube assembly 106 corresponds one-to-one with the multiple tube insertion holes; the first drive device 108 is mounted on the frame 100 and is adapted to drive the guide rod assembly 104 from the first initial position to the first tube insertion position, and is also adapted to drive the guide rod assembly 104 and the picking rod 102 from the first tube insertion position to the first initial position; the second drive device 110 is mounted on the frame 100 and is adapted to drive the heat exchange tube assembly 106 from the second initial position to the second tube insertion position.

[0067] According to the finned tube insertion device provided in the first aspect embodiment of the present invention, by pre-inserting a picking rod 102 into the finned assembly, and by driving the guide rod assembly 104 between a first initial position and a first insertion position via a first driving device 108, the picking rod 102 not only provides guidance for the heat exchange tube assembly 106 during insertion into the finned assembly, but also prevents the finned assembly from bursting or scattering during insertion. By driving the guide rod assembly 104 between the first initial position and the first insertion position via the first driving device 108, and by driving the heat exchange tube assembly 106 between the second initial position and the second insertion position via the second driving device 110, the insertion accuracy and automation level of the heat exchange tube assembly 106 during insertion can be improved. By driving the picking rod 102 from the first insertion position to the first initial position via the first driving device 108, the picking rod 102 can also be retrieved, facilitating the secondary insertion of the finned assembly.

[0068] Please continue reading Figures 1 to 9 The frame 100 is used to install the fin assembly, guide rod assembly 104, heat exchange tube assembly 106, first drive device 108 and second drive device 110. In this embodiment of the invention, the frame 100 may be made of metal material, which can improve the support strength and support stability of the above components.

[0069] In this embodiment of the invention, the frame 100 is generally divided into three areas: a fin fixing area corresponding to the fin assembly, a guide rod placement area corresponding to the guide rod assembly 104, and a heat exchange tube placement area corresponding to the heat exchange tube assembly 106. The fin fixing area is located between the guide rod placement area and the heat exchange tube placement area.

[0070] It is understandable that, such as Figure 1 and Figure 2 As shown, the fin fixing area is used to fix and install the fin assembly, the guide rod placement area is used to place the guide rod assembly 104 and the first driving device 108 for driving the guide rod assembly 104, and the heat exchange tube placement area is used to place the heat exchange tube assembly 106 and the second driving device 110 for driving the heat exchange tube assembly 106. Accordingly, the guide rod assembly 104 and the heat exchange tube assembly 106 are located on opposite sides of the fin assembly.

[0071] In this embodiment of the invention, the heat exchange tube assembly 106 is used to pass through the fin assembly, and the guide rod assembly 104 is used to provide guidance for the heat exchange tube assembly 106 during the process of passing through the fin assembly, so as to ensure the passing accuracy of the heat exchange tube assembly 106.

[0072] The fin assembly is placed on the frame 100. In this embodiment of the invention, the fin assembly has multiple through holes, and at least one of the through holes is used to insert a picking rod 102. The multiple through holes can be opened along the length or width of the fin assembly.

[0073] For example, the through-hole can be opened along the length of the fin assembly and penetrate the fin assembly. At least one of the through-holes is provided with a pick-up rod 102. In this embodiment of the invention, one pick-up rod 102 can be provided in each of the through-holes located on both sides. The pick-up rod 102 serves two purposes: firstly, it guides the heat exchange tube assembly 106 during the installation process; secondly, it provides support for the fin assembly during the installation process, preventing fin bursting or scattering due to inaccurate installation of the heat exchange tube assembly 106.

[0074] See Figure 1 , Figure 2In this embodiment of the invention, to achieve the positioning of the fin assembly, a positioning device 156 is provided on the frame 100 at a position corresponding to the fin fixing area. The positioning device 156 mentioned here can be a positioning stop disposed around the fin assembly. The positioning stop can move relative to the fin assembly to achieve coarse positioning of the fin assembly in the horizontal plane. The positioning stop can be installed on the frame 100 by means of screw connection. When it is necessary to adjust the relative position of the positioning stop and the fin assembly, the screws can be loosened, the positioning stop adjusted to a suitable position, and then the screws tightened to achieve the positioning and installation of the fin assembly.

[0075] Of course, in other embodiments, the fin assembly can be positioned in other ways, such as by electric cylinders, chucks, etc.

[0076] As mentioned above, the heat exchange tube assembly 106 includes heat exchange tube bodies 128 corresponding to a plurality of through holes. For example, the fin assembly has 24 through holes, and correspondingly, the heat exchange tube assembly 106 also includes 24 heat exchange tube bodies 128. This arrangement allows a heat exchange tube body 128 to be inserted into each through hole, thereby improving the structural strength of the fin assembly and enhancing its heat exchange performance.

[0077] In this embodiment of the invention, the heat exchange tube assembly 106 can switch between a second initial position and a second tube-through position under the drive of the second driving device 110. It should be noted that the second initial position mentioned here refers to... Figure 2 As shown in the lower position, when the heat exchange tube assembly 106 is in the second initial position, the heat exchange tube assembly 106 and the through-hole on the fin assembly are far apart. The second through-hole position refers to the position of the heat exchange tube assembly 106 when it is close to the through-hole on the fin assembly. When the heat exchange tube assembly 106 is in the second through-hole position, the heat exchange tube body 128 can contact the through-hole on the fin assembly. If the second driving device 110 continues to drive the heat exchange tube body 128 to move closer to the fin assembly, the heat exchange tube body 128 can be pushed into the through-hole on the fin assembly.

[0078] After the heat exchange tube body 128 is fully inserted into the through hole on the fin assembly, the second drive device 110 can automatically reset, that is, the second drive device 110 can switch from the second through position to the second initial position.

[0079] The guide rod assembly 104 is used to guide the heat exchange tube body 128 when it is inserted into the through hole on the fin assembly, so as to prevent the heat exchange tube body 128 from deviating during the insertion process.

[0080] In this embodiment of the invention, the guide rod assembly 104 includes a pick-up guide rod 130 and a guide rod body 132. The pick-up guide rod 130 is used to retrieve the pick-up rod 102, and the guide rod body 132 is used to guide the remaining heat exchange tube bodies 128 during the process of passing through the tube hole.

[0081] The part-removing guide rod 130 is correspondingly arranged with the part-removing rod 102. It can be understood that since the part-removing rod 102 is located in the through-holes on both sides of the fin assembly, the corresponding part-removing guide rod 130 is also located in a position corresponding to the through-holes on both sides of the fin assembly. After the part-removing rod 102 has completed its guiding function on the heat exchange tube body 128, the part-removing guide rod 130 is used to remove the part-removing rod 102 from the fin assembly, thereby realizing the recycling of the part-removing rod 102. This arrangement facilitates the secondary use of the part-removing rod 102.

[0082] As mentioned earlier, since the picking rod 102 can guide the heat exchange tube body 128 during its insertion into the tube hole, the end of the picking rod 102 that connects with the heat exchange tube body 128 can be tapered to facilitate the connection between the picking rod 102 and the heat exchange tube body 128. Similarly, to facilitate the connection between the picking guide rod 130 and the picking rod 102, the end of the picking rod 102 that connects with the picking guide rod 130 can also be tapered.

[0083] The guide rod body 132 can be set one-to-one with the through holes on the fin assembly where the picking rod 102 is not provided. For example, if the fin assembly has 24 through holes and the two picking rods 102 are respectively inserted into the through holes on both sides, then the guide rod body 132 can be set with 22 of them, and set one-to-one with the remaining 22 through holes.

[0084] The part-retrieving guide rod 130 and guide rod body 132 in the guide rod assembly 104 can switch between a first initial position and a first tube-penetrating position under the drive of the first driving device 108. It should be noted that the first initial position mentioned here refers to... Figure 2 As shown in the upper position, when the guide rod body 132 is in the first initial position, the guide rod body 132 and the through hole on the fin assembly are far apart. The first through position is the position where the guide rod assembly 104 is inserted into the through hole on the fin assembly.

[0085] Taking the guide rod body 132 as an example, when the guide rod body 132 is in the first through-tube position, it can be inserted into the through-tube hole on the fin assembly. If the heat exchange tube body 128 is in the second through-tube position, the guide rod body 132 can be inserted into the through-tube hole to guide the heat exchange tube body 128. When the guide rod body 132 switches from the first through-tube position to the first initial position, it gradually emerges from the through-tube hole, guiding the heat exchange tube body 128 into the through-tube hole. When the guide rod body 132 has fully moved to the first initial position, it separates from the heat exchange tube body 128.

[0086] Taking the retrieval guide rod 130 as an example, when the retrieval guide rod 130 is in the first through-tube position, it can be inserted into the through-tube hole on the fin assembly and connected to the first end of the retrieval rod 102. If the heat exchange tube body 128 is in the second through-tube position, the second end of the retrieval rod 102 can be connected to the heat exchange tube body 128 in the through-tube hole to guide the heat exchange tube body 128. When the retrieval guide rod 130 switches from the first through-tube position to the first initial position, it gradually emerges from the through-tube hole. At this time, the retrieval guide rod 130 can simultaneously drive the retrieval rod 102 to emerge from the through-tube hole, and the retrieval rod 102 simultaneously guides the heat exchange tube body 128 to be inserted into the through-tube hole. When the retrieval guide rod 130 has completely moved to the first initial position, the retrieval rod 102 is completely brought out of the through-tube hole, and the retrieval rod 102 can be recycled for reuse. Since the pick-up guide rod 130 only needs to cooperate with the pick-up rod 102, the length of the pick-up guide rod 130 is less than the length of the guide rod body 132.

[0087] In this embodiment of the invention, the guide rod assembly 104 can be driven by the first driving device 108 to move relative to the fin assembly.

[0088] See Figure 1 , Figures 7 to 9 According to one embodiment of the present invention, the first driving device 108 includes a first driving member 112, a first slider 114 and a first lead screw 116; wherein, the first driving member 112 is mounted on the frame 100, and the first driving member 112 can be a common motor or a stepper motor. In this embodiment of the present invention, the first driving member 112 uses a stepper motor, which can improve the motion accuracy of the guide rod assembly 104.

[0089] The first driving member 112 is adapted to drive the guide rod assembly 104 from the first initial position to the first through-tube position, and is also adapted to drive the guide rod assembly 104 and the retrieval rod 102 from the first through-tube position to the first initial position. As mentioned above, the guide rod body 132 and the retrieval guide rod 130 in the guide rod assembly 104 can switch between the first initial position and the first through-tube position under the drive of the first driving member 112. During the process of the guide rod body 132 and the retrieval guide rod 130 switching from the first through-tube position to the first initial position, the first driving member 112 can also drive the retrieval rod 102 to switch from the first through-tube position to the first initial position at the same time, so that the retrieval rod 102 can be recycled.

[0090] The first slider 114 is slidably mounted on the frame 100, and the first lead screw 116 is rotatably mounted on the first slider 114 and is connected to the first drive member 112 for transmission.

[0091] See Figure 1 , Figure 2 , Figures 7 to 9 Since the first driving member 112 is fixedly installed on the frame 100, in order to achieve the above-mentioned purpose, the first slider 114 can slide relative to the frame 100, and the first lead screw 116 is connected between the first slider 114 and the first driving member 112. With this configuration, when the first driving member 112 drives the first lead screw 116 to rotate, since the relative position of the first lead screw 116 and the first driving member 112 does not change, and the first slider 114 can move along the axial direction of the first lead screw 116, the purpose of driving the guide rod body 132 and the picking guide rod 130 to switch between the first initial position and the first tube insertion position, and driving the picking rod 102 to switch from the first tube insertion position to the first initial position can be achieved during the movement of the first slider 114 relative to the frame 100.

[0092] See Figures 1 to 9 According to one embodiment of the present invention, the first driving device 108 further includes a first guide assembly, which is movably mounted on the frame 100 and positioned between the first driving member 112 and the fin assembly to guide and cooperate with the guide rod assembly 104 and the picking rod 102.

[0093] By providing a first guide assembly on the frame 100, the guide rod body 132, the pick-up guide rod 130, and the pick-up rod 102 can be guided during the switching process between the guide rod body 132 and the pick-up guide rod 130 and the first tube insertion position, as well as during the switching process of the pick-up rod 102 from the first tube insertion position to the first initial position. This arrangement further improves the movement accuracy of the guide rod body 132, the pick-up guide rod 130, and the pick-up rod 102. Since the first guide assembly needs to perform the above functions, it is positioned between the first drive member 112 and the fin assembly.

[0094] Please continue reading Figure 4 and Figure 5 According to one embodiment of the present invention, the first guide assembly includes a first bracket 118, which is slidably mounted on the frame 100. A connecting plate 120 is provided on the first bracket 118, and a guide hole 122 corresponding to the guide rod assembly 104 is provided on the connecting plate 120.

[0095] In this embodiment of the invention, two sets of first supports 118 can be provided. The two sets of first supports 118 can be spaced apart along the axial direction of the first lead screw 116, with two first supports 118 in each set, respectively located on both sides of the frame 100. A connecting plate 120 is provided between the two first supports 118, and guide holes 122 are provided on the connecting plate 120 at positions corresponding to the guide rod and the picking guide rod 130. With this arrangement, the movement of the guide rod and the picking guide rod 130 can be guided by the guide holes 122. The diameter of the guide holes 122 can be slightly larger than the diameter of the guide rod and the picking guide rod 130, which can reduce the friction between the guide holes 122 and the guide rod and the picking guide rod 130.

[0096] According to one embodiment of the present invention, the first guide assembly further includes a first guide rail 124, the first guide rail 124 being disposed on the frame 100, and the first slider 114 and the first bracket 118 being guided and engaged with the first guide rail 124.

[0097] To improve the motion accuracy of the first slider 114 and the first support 118, a first guide rail 124 is also provided on the frame 100 along the axial direction of the first lead screw 116. The first guide rail 124 can be a protrusion structure provided on the frame 100, and correspondingly, the first slider 114 and the first support 118 are provided with groove structures that cooperate with the protrusion structure. When the first slider 114 and the first support 118 move relative to the frame 100, they can move along the direction of the first guide rail 124.

[0098] According to one embodiment of the present invention, a limiting structure is provided on the first guide rail 124, and the first bracket 118 is adapted to limit its relative position with the first guide rail 124 by the limiting structure along the length direction of the guide rail.

[0099] By setting a limiting structure on the first guide rail 124, the collision between the first support 118 and the fin assembly can be prevented, thereby ensuring the integrity of the fin assembly. The limiting structure mentioned here can be a limiting platform, limiting protrusion, or similar structure set on the first guide rail 124. It should be noted that the number of limiting structures corresponds one-to-one with the number of first supports 118. For example, if there are two first supports 118, then there are also two limiting structures, each used to position the two first supports 118. The limiting structures can be spaced apart along the length of the first guide rail 124. When the first first support 118 contacts the first limiting structure, the first first support 118 stops moving. At this time, since the first slider 114 can still move relative to the frame 100, the second first support 118 can still continue to move relative to the frame 100. When the second first support 118 contacts the second limiting structure, the second second support 136 stops moving.

[0100] According to one embodiment of the present invention, the finned tube insertion device further includes a clamping mechanism 126, which is disposed on the connecting plate 120. During the process of the part removal rod 102 switching from the first tube insertion position to the first initial position, the clamping mechanism 126 is adapted to clamp the part removal rod 102.

[0101] See Figure 5 A clamping mechanism 126 is also provided on the connecting plate 120 of the first support 118. This arrangement allows the clamping mechanism 126 to clamp the picking rod 102 when the picking guide rod 130 removes it from the through-hole of the fin assembly, ensuring the connection stability between the picking rod 102 and the picking guide rod 130. The clamping mechanism 126 can be a robotic arm or a gripper, etc. Correspondingly, to improve the automation level of the clamping mechanism 126, a corresponding detection element can be provided on the frame 100. When the detection element detects that the picking rod 102 has been removed, the clamping mechanism 126 can clamp the picking rod 102. Once the picking rod 102 is completely removed, the clamping mechanism 126 can release the picking rod 102, allowing it to fall for recycling.

[0102] See Figure 9 According to one embodiment of the present invention, a first connecting rod 115 is provided between the first bracket 118 and the first slider 114, and the first driving member 112 is adapted to drive the first slider 114 from the first tube-through position to the first initial position. The first slider 114 is adapted to drive the first bracket 118 through the first connecting rod 115.

[0103] A first connecting rod 115 is provided between the first slider 114 and the first support 118. With this arrangement, when the first slider 114 switches from the first initial position to the first through-tube position, after the first slider 114 contacts the first support 118, the first slider 114 can synchronously drive the first support 118 to move from the first initial position to the first through-tube position. When the first driving member 112 reverses, it can drive the first slider 114 to move from the first through-tube position to the first initial position. At this time, when the distance between the first slider 114 and the first support 118 reaches the length of the first connecting rod 115, the first connecting rod 115 can drive the first support 118 to move from the first through-tube position to the first initial position.

[0104] The movement of the guide rod assembly 104 is explained below:

[0105] Install the guide rod body 132 and the part-retrieving guide rod 130 onto the first slider 114 and the first bracket 118, and pass the guide rod body 132 and the part-retrieving guide rod 130 through the guide hole 122 on the connecting plate 120.

[0106] The first driving component 112 starts working, and the first driving component 112 drives the first slider 114 to move along the first guide rail 124. During the process of the first slider 114 moving from the first initial position to the first tube-passing position, the guide rod body 132 and the picking guide rod 130 move synchronously from the first initial position to the first tube-passing position.

[0107] When the first slider 114 contacts the first support 118, the first slider 114 can synchronously drive the first support 118 to move towards the first tube insertion position. When the guide rod body 132 and the part removal guide rod 130 are inserted into the tube insertion hole of the fin assembly, the guide rod body 132 and the part removal guide rod 130 are respectively connected to the heat exchange tube body 128 and the part removal rod 102.

[0108] The first driving component 112 reverses and drives the first slider 114 to move from the first tube insertion position to the first initial position. When the first slider 114 moves to a certain position, the first slider 114 drives the first bracket 118 to move to the first initial position through the first connecting rod 115. At the same time, the guide rod body 132, the picking guide rod 130 and the picking rod 102 move synchronously from the first tube insertion position to the first initial position.

[0109] According to one embodiment of the present invention, the second driving device 110 includes a second driving member 134 and a second guiding assembly; wherein, the second driving member 134 is adapted to drive the heat exchange tube assembly 106 from a second initial position to a second through-tube position. As described above, the heat exchange tube assembly 106 can be switched from the second initial position to the second through-tube position under the drive of the second driving member 134. During the process of switching the heat exchange tube assembly 106 from the second initial position to the second through-tube position, the second driving member 134 can insert the heat exchange tube assembly 106 into the through-tube hole on the fin assembly.

[0110] The second drive unit 134 is mounted on the frame 100. The second drive unit 134 can be a regular motor or a stepper motor. In this embodiment of the invention, the second drive unit 134 uses a stepper motor, which can improve the motion accuracy of the heat exchange tube assembly 106.

[0111] The second guide assembly is movably mounted on the frame 100 and positioned between the second drive member 134 and the fin assembly to guide and engage with the heat exchange tube assembly 106.

[0112] By providing a second guide assembly on the frame 100, the heat exchange tube assembly 106 can be guided during the process of switching from the second initial position to the second through-tube position. This arrangement can further improve the movement accuracy of the heat exchange tube assembly 106. Since the second guide assembly needs to perform the above-mentioned function, it is positioned between the second drive member 134 and the fin assembly.

[0113] Please continue reading Figure 3 and Figure 6 According to one embodiment of the present invention, the second guide assembly includes a second bracket 136 and a second lead screw 144; wherein, the second bracket 136 is slidably mounted on the frame 100, and the second bracket 136 is provided with an upper guide plate 138 and a lower guide plate 140 that are movable relative to each other, and the upper guide plate 138 and the lower guide plate 140 are respectively provided with snap-fit ​​grooves 142 that correspond one-to-one with the heat exchange tube assembly 106; the second lead screw 144 is connected to the second drive member 134 and the second bracket 136 to drive the second bracket 136 to move relative to the frame 100.

[0114] In this embodiment of the invention, two sets of second brackets 136 can be provided, and the two sets of second brackets 136 can be spaced apart along the axial direction of the second lead screw 144. Each set of second brackets 136 consists of two pieces, which are respectively provided on both sides of the frame 100. The second bracket 136 is provided with an upper guide plate 138 and a lower guide plate 140. The upper guide plate 138 and the lower guide plate 140 are respectively provided with snap-fit ​​grooves 142 that correspond one-to-one with the heat exchange tube assembly 106. When the upper guide plate 138 and the lower guide plate 140 are spliced ​​together, the snap-fit ​​grooves 142 on the upper guide plate 138 and the lower guide plate 140 can be connected to each other to form guide holes for guiding the heat exchange tube assembly 106.

[0115] The upper guide plate 138 and the lower guide plate 140 can move relative to each other. This arrangement allows the heat exchanger tube assembly 106 to be guided during its movement by the interlocking of the upper guide plate 138 and the lower guide plate 140. It should be noted that the diameter of the guide hole can be slightly larger than the diameter of the heat exchanger tube body 128, which reduces the friction between the guide hole and the heat exchanger tube body 128.

[0116] The second lead screw 144 is connected between the second drive member 134 and the second bracket 136, so as to drive the second bracket 136 to move relative to the frame 100 via the second drive member 134. With this configuration, when the second drive member 134 drives the second lead screw 144 to rotate, the relative position of the second lead screw 144 and the second drive member 134 does not change, while the second bracket 136 can move along the axial direction of the second lead screw 144. Therefore, when the second drive member 134 moves, the purpose of driving the second bracket 136 to move relative to the frame 100 can be achieved.

[0117] See Figure 2 , Figure 4 and Figure 7 According to one embodiment of the present invention, the second guide assembly further includes a second slider 146 and a second guide rail 150; wherein the second slider 146 is slidably mounted on the frame 100, the second lead screw 144 is rotatably connected between the second slider 146 and the frame 100, and a second connecting rod 148 is connected between the second slider 146 and the second support 136; the second guide rail 150 is disposed on the frame 100, and the second support 136 and the second slider 146 are guided and cooperate with the second guide rail 150.

[0118] To improve the motion accuracy of the second support 136, a second guide rail 150 is also provided on the frame 100 along the axial direction of the second lead screw 144. A second slider 146 is provided on the second guide rail 150 and guides and cooperates with the second guide rail 150. When the second drive member 134 is actuated, since the relative position of the second lead screw and the second drive member 134 does not change, the second lead screw 144 can drive the second slider 146 to move along the axial direction of the second guide rail 150.

[0119] A second connecting rod 148 is provided between the second slider 146 and the second support 136. This arrangement allows the second slider 146 to synchronously move the second support 136 from the second initial position to the second through-tube position after contacting the second support 136 during the transition from the second initial position to the second through-tube position. When the second driving member 134 reverses its direction, it can move the second slider 146 from the second through-tube position back to the second initial position. At this time, when the distance between the second slider 146 and the second support 136 reaches the length of the second connecting rod 148, the second support 136 can be moved from the second through-tube position back to the second initial position via the second connecting rod 148.

[0120] In this embodiment of the invention, the second guide rail 150 may be a protrusion structure disposed on the frame 100. Correspondingly, the second slider 146 and the second bracket 136 are provided with groove structures that cooperate with the protrusion structure. When the second slider 146 and the second bracket 136 move relative to the frame 100, they can move along the direction of the second guide rail 150.

[0121] The movement of the heat exchanger assembly 106 is explained below:

[0122] The heat exchange tube body 128 is installed on the second slider 146 and the second bracket 136, and the upper guide plate 138 and the lower guide plate 140 are brought close to each other so that the heat exchange tube body 128 is snapped into the guide hole on the upper guide plate 138 and the lower guide plate 140.

[0123] The second driving element 134 starts working, and the second driving element 134 drives the second slider 146 to move along the second guide rail 150. During the process of the second slider 146 moving from the second initial position to the second tube position, the heat exchange tube body 128 moves synchronously from the second initial position to the second tube position.

[0124] When the second slider 146 contacts the second bracket 136, the second slider 146 can synchronously drive the second bracket 136 to move to the second tube position. When the heat exchange tube body 128 is inserted into the tube hole of the fin assembly, the heat exchange tube body 128 is connected with the guide rod body 132 and the picking rod 102.

[0125] The second driving component 134 reverses and drives the second bracket 136 to move from the second through-tube position to the second initial position. When the second bracket 136 moves to a certain position, the second bracket 136 moves to the second initial position through the second connecting rod 148.

[0126] According to one embodiment of the present invention, the finned tube insertion device further includes a recovery belt 152, which is disposed on the frame 100, and a guide plate 154 is disposed on the frame 100 at a position corresponding to the guide rod assembly 104 and the recovery belt 152.

[0127] See Figure 1 and Figure 3 A recovery belt 152 is installed on the frame 100 at a position corresponding to the guide rod placement area. After the picking rod 102 is taken out by the picking guide rod 130, it can fall onto the recovery belt 152. In order to ensure that the picking rod 102 can fall accurately onto the recovery belt 152, a guide plate 154 is also provided on the frame 100. When the picking rod 102 falls from the guide rod placement area, it can be guided by the guide plate 154 to fall onto the recovery belt 152.

[0128] A second aspect of the present invention provides a method of using the above-described finned tube insertion device, comprising:

[0129] Step 500: Place the fin assembly on the frame 100 and position the fin assembly using the positioning device 156;

[0130] Step 600: The guide rod assembly 104 is switched from the first initial position to the first tube insertion position by the first driving device 108;

[0131] Step 700: The heat exchange tube assembly 106 is switched from the second initial position to the second through-tube position by the second driving device 110, so that the heat exchange tube assembly 106 is connected with the guide rod assembly 104 and the picking rod 102.

[0132] Step 800: The guide rod assembly 104 and the picking rod 102 are switched from the first tube insertion position to the first initial position by the first driving device 108, so as to retrieve the picking rod 102 and insert the heat exchange tube assembly 106 into the tube insertion hole.

[0133] According to the second aspect of the present invention, the method of using the finned tube insertion device can not only accurately insert the heat exchange tube assembly 106 into the insertion hole in the fin assembly, but also prevent the fin assembly from bursting or scattering during the insertion of the heat exchange tube assembly 106, and can also realize the recovery of the picking rod 102.

[0134] See Figure 10In step 500, the fin assembly is first placed in the fin fixing area on the frame 100, and the fin assembly is coarsely positioned by the positioning device 156. At this time, the fin assembly is coarsely positioned on the frame 100.

[0135] In step 600, the guide rod body 132 and the part-retrieving guide rod 130 are installed on the first slider 114 and the first bracket 118, and the guide rod body 132 and the part-retrieving guide rod 130 are passed through the guide hole 122 on the connecting plate 120.

[0136] The first drive starts working, the first drive component 112 drives the first connecting rod 115 to rotate, and the first connecting rod 115 synchronously drives the first slider 114 to move along the first guide rail 124. During the process of the first slider 114 moving from the first initial position to the first tube-passing position, the guide rod body 132 and the part-taking guide rod 130 synchronously move from the first initial position to the first tube-passing position.

[0137] When the first slider 114 comes into contact with the first bracket 118, the first slider 114 can synchronously drive the first bracket 118 to move towards the first tube position.

[0138] In step 700, the heat exchange tube body 128 is installed on the second slider 146 and the second bracket 136, and the upper guide plate 138 and the lower guide plate 140 are brought close to each other so that the heat exchange tube body 128 is snapped into the guide hole on the upper guide plate 138 and the lower guide plate 140.

[0139] The second drive starts working, the second drive component 134 drives the second connecting rod 148 to rotate, and the second connecting rod 148 synchronously drives the second slider 146 to move along the second guide rail 150. During the process of the second slider 146 moving from the second initial position to the second tube-through position, the heat exchange tube body 128 synchronously moves from the second initial position to the second tube-through position.

[0140] When the second slider 146 comes into contact with the second bracket 136, the second slider 146 can synchronously drive the second bracket 136 to move towards the second tube position.

[0141] In step 800, when the guide rod body 132 and the part-removing guide rod 130 are inserted into the through hole of the fin assembly, and at the same time, when the heat exchange tube body 128 is inserted into the through hole of the fin assembly, the guide rod body 132 and the part-removing rod 102 are respectively connected to the heat exchange tube body 128 at one end, and the part-removing rod 102 is connected to the part-removing guide rod 130 at the other end away from the heat exchange tube body 128.

[0142] The first driving component 112 reverses, causing the first connecting rod 115 to reverse. At this time, the first slider 114 moves from the first tube-through position to the first initial position. When the first slider 114 moves to a certain position, the first slider 114 drives the first bracket 118 to move to the first initial position through the first connecting rod 115. At the same time, the guide rod body 132, the picking guide rod 130, and the picking rod 102 move synchronously from the first tube-through position to the first initial position.

[0143] When the picking rod 102 moves to the position corresponding to the clamping mechanism 126 on the first bracket 118, the clamping mechanism 126 clamps the picking rod 102. When the first slider 114 drives the first bracket 118 back to the first initial position, the clamping mechanism 126 releases the picking rod 102, and the picking rod 102 falls down. Guided by the guide plate 154, it falls onto the recycling belt 152. The recycling belt 152 transports the picking rod 102 to the recycling box.

[0144] The second driving component 134 reverses, causing the second connecting rod 148 to reverse. At this time, the second bracket 136 moves from the second through-tube position to the second initial position. When the second bracket 136 moves to a certain position, the second bracket 136 moves to the second initial position through the second connecting rod 148.

[0145] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
