Description

Technical Field

[0001] This invention relates to the technical field of condenser assembly lines, and more specifically to an assembly line for condenser fins and flat tubes arranged alternately. Background Technology

[0002] The condenser is one of the core components of the radiator in engineering vehicles. It is mainly used to condense the high-temperature and high-pressure gaseous refrigerant discharged from the compressor into a liquid state through heat exchange, releasing heat to the external environment, thereby maintaining the efficient operation of the engine and hydraulic system.

[0003] Condenser such as Figure 1 As shown, the condenser includes a circular tube 1, multiple flat tubes 2, and multiple fins 3. The flat tubes 2 and fins 3 are arranged alternately. The flat tubes 2 are connected to the circular tube 1. Gaseous refrigerant flows through the circular tube 1 into the flat tube 2, where it transfers heat to the fins 3. The heat is then released into the air through the fins 3, thus achieving the function of cooling the refrigerant. Traditional condenser assembly mainly relies on manual arrangement of the flat tubes 2 and fins 3, which is time-consuming, labor-intensive, and has low production efficiency.

[0004] Chinese utility model patent application CN204487133U discloses a manual assembly device for finned condensers, including a base, a workpiece fixing structure, and an alignment structure. The base, connected to the workpiece fixing and alignment structures, includes a platform 1, a right plate 2, a left plate 3, and a stop block 5. The right plate 2 and left plate 3 are mounted on the platform 1 via front and rear support beams 4, respectively. The stop block 5 is vertically mounted on the front side of the platform 1. The workpiece fixing and alignment structures are symmetrical. The workpiece fixing structure, located in the middle of the left and right alignment structures, is the core of this device. The alignment structure is fixed to the right plate 2 and is used to align the flat tubes and compress the manifold. This design ensures smooth sliding of the upright block without damaging the flat tubes. The added comb teeth ensure that the flat tubes remain vertical and do not tilt when the upright block is pulled open, facilitating the insertion of fins. It increases the continuity of assembly actions and the interlocking constraints between actions, relatively improving worker efficiency and safety. However, this manual assembly device still requires manual placement of fins and flat tubes, resulting in low production efficiency.

[0005] In summary, the existing technology requires a device that can automatically and alternately place flat tubes and fins to facilitate the assembly of condensers. Summary of the Invention

[0006] To address the aforementioned technical problems, the present invention aims to provide an assembly line for alternating arrangement of condenser fins and flat tubes, comprising a main frame, an alternating feeding device, a feeding plate, and a positioning and clamping device. This assembly line for alternating arrangement of condenser fins and flat tubes has the advantage of being able to alternately place flat tubes and fins, facilitating condenser assembly, improving condenser production efficiency, saving time and labor, and reducing labor costs.

[0007] To achieve the above-mentioned objectives, the technical solution adopted by the present invention is as follows:

[0008] An assembly line for condenser fins and flat tubes arranged alternately includes a main frame, an alternating feeding device, a feeding plate, and a positioning and clamping device. The alternating feeding device, feeding plate, and positioning and clamping device are all mounted on the main frame. The alternating feeding device and positioning and clamping device are located at opposite ends of the feeding plate. The alternating feeding device includes a fixed frame, a flat tube feeding mechanism, and a fin feeding mechanism. The fixed frame is fixedly connected to the main frame. The flat tube feeding mechanism includes a storage frame, a flat tube pusher plate, and a pusher plate drive component. All driving components are fixedly mounted on the fixed frame. The flat tube pusher plate is fixedly connected to the output end of the pusher plate. The bottom of the storage frame is provided with a flat tube through groove for the flat tube pusher plate to pass through. The fin feeding mechanism includes a conveyor belt, a fin pusher plate and a fin driving component. The conveyor belt and the fin driving component are mounted on the fixed frame. The fin pusher plate is fixedly connected to the output end of the fin driving component. The fixed frame is provided with a feeding trough located between the storage frame and the conveyor belt. One end of the feeding plate is fixedly connected to the fixed frame and located below the feeding trough.

[0009] With this setup, the flat tube feeding mechanism and the fin feeding mechanism alternately feed flat tubes and fins into the feeding trough, allowing the flat tubes and fins to move alternately through the feeding trough to the top of the feeding plate. This enables the flat tubes and fins to be arranged alternately on the feeding plate, realizing the function of alternating placement of flat tubes and fins by the equipment. This facilitates the assembly of the condenser, improves the production efficiency of the condenser, saves time and labor, and reduces labor costs.

[0010] Preferably, the feeding plate includes a vertical section, an arc section, and an inclined section. The two ends of the arc section smoothly transition to the vertical section and the inclined section, respectively. The upper and lower ends of the vertical section are fixedly connected to the fixed frame and the arc section, respectively. The end of the inclined section away from the arc section is inclined upward.

[0011] This setup ensures that the flat tube and fins remain stable as they move on the feed plate.

[0012] Preferably, the fixing frame is fixedly installed with a pressing drive, and the output end of the pressing drive is fixedly connected to a pressing plate. The pressing drive drives the pressing plate to press downward into the feeding groove.

[0013] This design prevents flat tubes and fins from getting stuck in the feed chute.

[0014] Preferably, the feeding plate is fixedly connected to both sides of the feeding plate.

[0015] This design prevents the flat tubes and fins from accidentally slipping off the sides of the feed plate, while also increasing the structural strength of the feed plate.

[0016] Preferably, the support baffle is provided with a sliding groove and a sliding frame. The sliding frame is fixedly connected with two guide rods passing through the sliding groove. The guide rods are rotatably connected to pulleys located in the sliding groove. The support baffle is provided with a clamping plate. The two guide rods pass through the clamping plate. The clamping plate and the sliding frame are respectively engaged with the two sides of the support baffle. The clamping plate is provided with screws threaded to the sliding frame. The sliding frame is provided with a retaining plate on the side near the feeding trough.

[0017] With this setup, when the flat tubes and fins are initially fed onto the feeding plate, the flat tubes and fins are supported by the clamps on the sliding frame, so that the flat tubes and fins do not fall too high after passing through the feeding chute, and the flat tubes and fins can make stable contact.

[0018] Preferably, the sliding groove is provided with a synchronous section and a deviating section. The distance between any two positions of the synchronous section and the feeding plate is the same. The deviating section is connected to the end of the synchronous section away from the feeding groove and transitions smoothly. The distance between the deviating section and the feeding plate gradually increases along the direction away from the synchronous section.

[0019] This setup allows the flat tube and materials to move onto the inclined section and assembly control panel.

[0020] Preferably, two storage frames are provided. Each storage frame has a storage trough that extends vertically and opens toward the other storage frame. A top material drive is fixedly installed on the fixing frame, and the output end of the top material drive is fixedly connected to a top block located between the two storage frames.

[0021] This design reduces the resistance encountered when the flat tube pusher plate pushes the flat tube at the bottom of the storage tank.

[0022] Preferably, the positioning and clamping device includes an assembly operation plate and a leveling positioning mechanism. The assembly operation plate is fixedly installed on the main frame, and the assembly operation plate smoothly transitions away from the feeding plate and the alternating feeding device. The leveling positioning mechanism includes a mounting frame, a rotating rod, and two positioning frames. The middle part of the rotating rod is rotatably connected to the mounting frame, and the positioning frames are slidably connected to the mounting frame. A connecting rod is provided between the positioning frames and the rotating rod. The two positioning frames are rotatably connected to the two connecting rods respectively. The two ends of the rotating rod are rotatably connected to the two connecting rods respectively. The mounting frame is provided with a positioning drive component that drives the connecting rod to rotate, and a positioning plate is fixedly connected to the positioning frame.

[0023] With this setup, two positioning plates can be aligned with the flat tube and fins from both ends, ensuring that the flat tube and fins are neatly arranged.

[0024] Preferably, the main frame is fixedly mounted with a clamping drive unit located at the end of the assembly operation plate away from the feeding plate. The output end of the clamping drive unit is fixedly connected to a pressure plate. The main frame is provided with a limiting plate. One end of the limiting plate is rotatably connected to the main frame. The limiting plate is located above the assembly operation plate and at the end of the positioning plate near the feeding plate. The pressure plate moves towards the limiting plate. The movement direction of the pressure plate is perpendicular to that of the positioning plate. The main frame is fixedly connected with a support block. The support block is provided with a slot for the limiting plate to be inserted.

[0025] This configuration facilitates the installation of round tubes at the ends of the flat tubes and fins.

[0026] Preferably, the mounting bracket is fixedly connected to a sliding rod that is vertically slidably connected to the main frame, and the main frame is equipped with a lifting drive component connected to the mounting bracket.

[0027] This design allows the positioning plate to be moved away from the end of the flat tube and fins, thus freeing up space for the round tube to be installed at the end of the flat tube, which facilitates the assembly of the round tube.

[0028] Compared with the prior art, the present invention has achieved beneficial technical effects:

[0029] The flat tube feeding mechanism and the fin feeding mechanism alternately feed flat tubes and fins to the feeding trough, allowing the flat tubes and fins to move alternately through the feeding trough to the top of the feeding plate. This enables the flat tubes and fins to be arranged alternately on the feeding plate, realizing the function of alternating placement of flat tubes and fins by the equipment. This facilitates the assembly of the condenser, improves the production efficiency of the condenser, saves time and labor, and reduces labor costs. Attached Figure Description

[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the embodiments. However, the scope of protection of this invention is not limited to the specific embodiments described below.

[0041] refer to Figure 1 An assembly line for condenser fins and flat tubes arranged alternately includes a main frame 11, an alternating feeding device, a feeding plate 31, and a positioning and clamping device. The alternating feeding device, the feeding plate 31, and the positioning and clamping device are all installed on the main frame 11, and the alternating feeding device and the positioning and clamping device are located at both ends of the feeding plate 31, respectively.

[0042] The alternating feeding device includes a fixed frame 12, a flat tube feeding mechanism, and a fin feeding mechanism, which are respectively arranged on both sides of the feeding trough 13. The fixed frame 12 is fixedly connected to the main frame 11. The flat tube feeding mechanism includes a storage frame 14, a flat tube push plate 21, and a push tube drive component 22. The storage frame 14 and the push tube drive component 22 are both fixedly installed on the fixed frame 12. The flat tube push plate 21 is fixedly connected to the output end of the push tube drive component 22. The bottom of the storage frame 14 is provided with a flat tube through groove 15 for the flat tube push plate 21 to pass through. There are two storage frames 14. Each storage frame 14 has a storage trough 16 that extends vertically and opens towards the other storage frame 14. The storage trough 16 communicates with the flat tube through groove 15. The fixed frame 12 is fixedly installed with a top material drive component 28. The output end of the top material drive component 28 is fixedly connected to a top block 29 located between the two storage frames 14. The fin feeding mechanism includes a conveyor belt 23, a fin pusher plate 24, and a fin drive component 25. The conveyor belt 23 and the fin drive component 25 are mounted on a fixed frame 12. The fin pusher plate 24 is fixedly connected to the output end of the fin drive component 25. The fixed frame 12 is provided with a feeding trough 13 located between the storage frame 14 and the conveyor belt 23. One end of the feeding plate 31 is fixedly connected to the fixed frame 12 and located below the feeding trough 13.

[0043] The storage frame 14 is used to store flat tubes, and the conveyor belt 23 is used to convey fins. The flat tubes on the storage frame 14 and the fins on the conveyor belt 23 are parallel and horizontal, so that the flat tubes and fins entering the feeding trough 13 one after another can be stably flat and aligned. The storage frame 14 is located between the flat tube push plate 21 and the feeding trough 13, and the conveyor belt 23 is located between the fin push plate 24 and the feeding trough 13.

[0044] The fixed frame 12 is fixedly installed with a pressing drive 26. The output end of the pressing drive 26 is fixedly connected to a pressing plate 27. The pressing drive 26 drives the pressing plate 27 to press downward into the feeding groove 13.

[0045] The feeding plate 31 includes a vertical section 32, an arc section 33 and an inclined section 34. The two ends of the arc section 33 smoothly transition to the vertical section 32 and the inclined section 34 respectively. The upper and lower ends of the vertical section 32 are fixedly connected to the fixed frame 12 and the arc section 33 respectively. The end of the inclined section 34 away from the arc section 33 is inclined upward. The vertical section 32 is set vertically.

[0046] Supporting baffles 35 are fixedly connected to both sides of the feeding plate 31. Each supporting baffle 35 has a sliding groove 36 and a sliding frame 41. Two guide rods 42, passing through the sliding groove 36, are fixedly connected to the sliding frame 41. The guide rods 42 are rotatably connected to pulleys 43 located within the sliding groove 36. The supporting baffle 35 has a clamping plate 44, through which the two guide rods 42 pass. The clamping plate 44 and the sliding frame 41 are respectively engaged with both sides of the supporting baffle 35. Screws 45 threadedly connect the clamping plate 44 to the sliding frame 41. A retaining plate 46 is provided on the side of the sliding frame 41 closest to the feeding trough 13. The sliding groove 36 has a synchronous section 37 and a deflection section 38. The distance between any two positions of the synchronous section 37 and the feeding plate 31 is the same. The deflection section 38 is connected to the end of the synchronous section 37 furthest from the feeding trough 13 and transitions smoothly. The distance between the deflection section 38 and the feeding plate 31 gradually increases along the direction away from the synchronous section 37.

[0047] The positioning and clamping device includes an assembly operation plate 51 and a leveling positioning mechanism. The assembly operation plate 51 is fixedly installed on the main frame 11. The assembly operation plate 51 and the feeding plate 31 smoothly transition away from the alternating feeding device. The leveling positioning mechanism includes a mounting frame 61, a rotating rod 63, and two positioning frames 65. The middle part of the rotating rod 63 is rotatably connected to the mounting frame 61. The positioning frames 65 are slidably connected to the mounting frame 61. A connecting rod 64 is provided between the positioning frames 65 and the rotating rod 63. The two positioning frames 65 are rotatably connected to the two connecting rods 64 respectively. The rotating rod 63 is a cylinder whose two ends are rotatably connected to the two connecting rods 64 respectively. The mounting frame 61 is provided with a positioning drive component 62 that drives the connecting rod 64 to rotate. The two ends of the positioning drive component 62 are rotatably connected to the mounting frame 61 and the connecting rod 64 respectively. A positioning plate 66 is fixedly connected to the positioning frame 65. A sliding rod 67 is fixedly connected to the mounting frame 61 and slidably connected to the main frame 11. A lifting drive component 68 connected to the mounting frame 61 is installed on the main frame 11.

[0048] The main frame 11 is fixedly mounted with a clamping drive 52 located at the end of the assembly operation plate 51 away from the feeding plate 31. The output end of the clamping drive 52 is fixedly connected to a pressure plate 53. The main frame 11 is provided with a limiting plate 54. One end of the limiting plate 54 is rotatably connected to the main frame 11. The limiting plate 54 is located above the assembly operation plate 51 and at the end of the positioning plate 66 near the feeding plate 31. The pressure plate 53 moves toward the limiting plate 54. The movement direction of the pressure plate 53 is perpendicular to that of the positioning plate 66. The main frame 11 is fixedly connected with a support block 55. The support block 55 is provided with a slot 56 for the limiting plate 54 to be inserted.

[0049] The push tube drive 22, fin drive 25, pressing drive 26, ejector drive 28, positioning drive 62, clamping drive 52, and lifting drive 68 are all cylinders. Each of these components is equipped with a solenoid valve to control its movement. A PLC module is connected to each of these components respectively. The PLC module controls the push tube drive 22, fin drive 25, pressing drive 26, ejector drive 28, positioning drive 62, clamping drive 52, and lifting drive 68 according to a preset program, thereby improving the automation rate.

[0050] The conveyor belt 23 is driven by a motor. A first photoelectric sensor 71 is fixedly installed on the mounting frame 12 above the conveyor belt 23. The first photoelectric sensor 71 is located at the end of the feeding trough near the conveying direction of the conveyor belt 23. The first photoelectric sensor 71 is used to sense whether there are fins on the conveyor belt 23. Both the first photoelectric sensor 71 and the motor of the conveyor belt 23 are electrically connected to the PLC module. When the first photoelectric sensor detects fins, the PLC module controls the motor to stop operating, so that the conveyor belt 23 stops conveying fins, preventing fins from accumulating on the conveyor belt 23, and ensuring that the fin pusher plate 24 can only push one fin into the feeding trough 13 at a time.

[0051] A second photoelectric sensor, electrically connected to the PLC module, is fixedly installed at one end of the support baffle 35 near the assembly operation plate 51. The second photoelectric sensor 72 is used to sense whether there are flat tubes and fins at the end of the feeding plate 31 near the assembly operation plate 51. When the second photoelectric sensor 72 senses that flat tubes and fins have arrived at the end of the feeding plate 31 near the assembly operation plate 51, the PLC module controls the alternating feeding device to stop feeding flat tubes and fins to the feeding plate 31 to prevent material blockage. Detailed Implementation

[0053] In the initial state, multiple flat tubes are vertically stacked in the storage tank 16, and the sliding frame 41 is located at one end of the sliding tank 36 near the feeding tank 13.

[0054] The flat tube is placed into the discharge chute, and the fins are placed on the conveyor belt 23. The tube pusher 22 drives the flat tube pusher plate 21 to move upward to the feed chute 13, and moves the flat tube in the storage frame 14 through the flat tube through slot 15 to the feed chute 13, where it falls onto the clamping plate 46 and the feeding plate 31. The tube pusher 22 then drives the flat tube pusher plate 21 to move away from the feed chute 13 and back to its original position. Then, the pressing loader 26 drives the pressing plate 27 to press downward into the feed chute 13, causing the pressing plate 27 to push the flat tube and the sliding frame 41 downward. The pressing loader 26 then drives the pressing plate 27 to move upward back to its original position. The fins are placed on the conveyor belt 23, which moves them between the fin pusher plate 24 and the feeding trough 13. The fin drive unit 25 moves the fin pusher plate 24 to the feeding trough 13, pushing the fins into the feeding trough 13 and onto the flat tube and feeding plate 31. The fin drive unit then moves the electric fin pusher plate 24 away from the feeding trough 13 to return to its original position. Then, the pressing drive unit 26 moves the pressing plate 27 downward into the feeding trough 13, causing the pressing plate 27 to push the fins, flat tube, and sliding frame 41 downward. The pressing drive unit 26 then moves the pressing plate 27 upward back to its original position, thus realizing the function of alternately feeding flat tubes and fins to the feeding plate 31 through the alternating feeding device. By repeating this alternating feeding of flat tubes and fins, the alternately arranged flat tubes and fins can be continuously fed to the feeding plate 31.

[0055] As more and more flat tubes and fins are added to the feeding plate 31, the clamping plate 46 and the sliding frame 41 are pushed from the synchronous section 37 to the deflection section 38, and then move along the extension direction of the deflection section 38, so that the distance between the clamping plate 46 and the feeding plate 31 gradually increases, thereby causing the clamping plate 46 to detach from the flat tubes and fins, while the flat tubes and fins move along the feeding plate 31 to the inclined section 34 under the push of the pressure plate 27.

[0056] Rotate the limiting plate 54 away from the assembly operation plate 51. The operator pushes a specified number of fins and flat tubes from the inclined section 34 onto the assembly operation plate 51, and then rotates the limiting plate 54 towards the assembly operation plate 51, so that the limiting plate 54 is engaged in the slot 56. The lifting drive 68 drives the mounting frame 61, the positioning frame 65, and the positioning plate 66 to move upward, so that the height of the positioning plate 66 is slightly higher than the assembly operation plate 51. Then, the positioning drive 62 drives the rotating rod 63 to rotate. The rotating rod 63 drives the positioning frame 65 and the positioning plate 66 to move towards the fins and flat tubes through the connecting rod 64. The positioning plate 66 is brought close to the ends of the fins and flat tubes, aligning the ends of the fins and flat tubes. Then, the pressing drive 52 drives the pressure plate 53 to move towards the limiting plate 54, so that the pressure plate 53 and the limiting plate 54 press the flat tubes and fins together, so that the multiple flat tubes and fins arranged alternately can be closely attached. Then, the positioning drive 62, through the rotating rod 63 and connecting rod 64, drives the positioning frame 65 to move away from the flat tube and fins back to its original position. The lifting drive 68 drives the mounting frame 61 to move downwards back to its original position, preventing the positioning plate 66 and the positioning frame 65 from blocking the end of the flat tube. This allows for easy installation of the round tube at the end of the flat tube, thus facilitating the assembly of the condenser.

[0057] This embodiment has the following advantages:

[0058] The flat tube feeding mechanism and the fin feeding mechanism alternately feed flat tubes and fins to the feeding trough 13, so that the flat tubes and fins can move alternately through the feeding trough 13 to the top of the feeding plate 31. This allows the flat tubes and fins to be arranged alternately on the feeding plate 31, realizing the function of alternately placing flat tubes and fins through the equipment. This facilitates the assembly of the condenser, improves the production efficiency of the condenser, saves time and labor, and saves labor costs.

[0059] As the flat tube and fins pass through the feeding plate 31, they slide down along the extension direction of the vertical section 32, then smoothly transition to the arc section 33, and then smoothly transition from the arc section 33 to the inclined section 34, thus keeping the flat tube and fins stable during their movement on the feeding plate 31.

[0060] As the flat tubes and fins are continuously fed onto the feeding plate 31, a portion of the flat tubes and fins are located at the end of the arc section 33 near the inclined section 34. Since the end of the inclined section 34 near the positioning and pressing device is inclined upward, the end where the arc section 33 and the inclined section 34 smoothly transition is also tilted upward. Thus, the flat tubes and fins located at the end of the arc section 33 near the inclined section 34 and on the inclined section 34, as well as the friction of the flat tubes and fins on the surface of the feeding plate 31, prevent the flat tubes and fins on the arc section 33 and the vertical section 32 from sliding freely, thereby improving the stability of the flat tubes and fins on the feeding plate 31. This ensures that the flat tubes and fins can only slide on the feeding plate 31 under the push of the pressing drive 26 and the pressing plate 27, so that the height of the flat tubes and fins falling freely after passing through the feeding trough 13 is not too high, and the flat tubes and fins can make stable contact.

[0061] When the flat tubes and fins on the vertical section 32 are full, the material in the feeding trough is stuck in the feeding trough. The pressing drive 26 drives the pressing plate 27 downward to fix the flat tubes and fins in the feeding trough, thereby pushing the flat tubes and fins on the feeding plate 31 to move towards the positioning and pressing device, preventing the flat tubes and fins from being blocked in the feeding trough 13.

[0062] The support baffle 35 can block the flat tubes and fins on the feed plate 31, preventing them from accidentally slipping off from both sides of the feed plate 31. At the same time, the support baffle 35 can also provide support for the feed plate 31, improving the structural strength of the feed plate 31.

[0063] At the beginning of processing, there are no flat tubes and fins on the feeding plate 31. If the flat tubes and fins fall directly from the feeding trough 13 onto the feeding plate 31, they are prone to tumbling on the feeding plate 31, causing deviations in the placement angle of the flat tubes and fins. Operators need to adjust the placement angle of the flat tubes and fins on the assembly operation plate 51, which affects production efficiency. Therefore, at the beginning of processing, slide the sliding frame 41 to a position close to the feeding trough 13, rotate the screw 45 to apply pressure to the clamping plate 46, and generate friction between the clamping plate 46 and the support baffle 35. By rotating the screw 45, the friction between the clamping plate 46 and the support baffle 35 is sufficient to prevent the fins and flat tubes from sliding freely on the feeding plate 31, and ensure that the push tube drive 22 and the ejector plate can push the sliding frame 41 and the clamping plate 46 to slide on the support baffle 35. (During the equipment installation and commissioning process, if the sliding frame 41 cannot stably support the flat tubes and fins, tighten the screw 45; if the pressing drive 26 and the pressing plate 27 cannot push the sliding frame 41, loosen the screw 45. The adjustment of the screw 45 can be completed after a limited number of repeated adjustments.) When the flat tubes and fins are initially fed onto the feeding plate 31, the clamping plate 46 on the sliding frame 41 supports the flat tubes and fins, keeping them stable on the vertical section 32 and close to the feeding trough 13. This prevents the flat tubes and fins from falling too far after passing through the feeding trough 13, ensuring smooth contact between them. After the flat tubes or fins enter the feeding trough 13, the pusher drive 22 and the ejector plate push the flat tubes, fins, and sliding frame 41 away from the feeding trough 13, thus enabling continuous and stable feeding of the flat tubes and fins onto the feeding plate 31.

[0064] During the movement of the sliding frame 41 along the synchronous section 37, the clamping plate 46 can contact the flat tube and fins; after the flat tube and fins push the clamping plate 46 and the sliding frame 41 to the deviation section 38, they can gradually move away from the feeding plate 31 along the extension direction of the deviation section 38, so that the flat tube and material can move to the inclined section 34 and the assembly operation plate 51.

[0065] When the flat tube pusher plate 21 pushes the flat tube at the bottom of the storage tank 16, the top material drive member 28 drives the top block 29 to move towards the flat tube and pushes the flat tube in the middle position, preventing the flat tube in the middle position and the top from pressing down on the flat tube pusher plate 21, thereby reducing the resistance encountered by the flat tube pusher plate 21 when pushing the flat tube at the bottom of the storage tank 16.

[0066] When the electric rotating rod 63 of the positioning drive component 62 rotates, the rotating rod 63 can synchronously drive the two positioning frames 65 to move in opposite directions through the two connecting rods 64. This causes the two positioning frames 65 and the positioning plate 66 to simultaneously approach and clamp the two ends of the flat tube and the fin, aligning the ends of the flat tube and the fin on the assembly operation plate 51. Thus, the two positioning plates 66 can be aligned with the flat tube and the fin from both ends, ensuring that the flat tube and the fin are neatly arranged.

[0067] The clamping drive 52 drives the pressure plate 53 to move toward the limiting plate 54, so that the pressure plate 53 and the limiting plate 54 flat tube and fin are close together to eliminate gaps, and can keep the flat tube and fin stable when the positioning plate 66 releases the flat tube and fin, thus facilitating the installation of round tubes at the ends of the flat tube and fin.

[0068] The lifting drive component 68 drives the mounting bracket 61, positioning bracket 65 and positioning plate 66 to move downward, so that the positioning plate 66 is away from the end of the flat tube and fins, thereby freeing up space to install the round tube at the end of the flat tube, which facilitates the assembly of the round tube.

Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on the invention.
