Description

Technical Field

[0001] This invention relates to a radiator fin-flat tube assembly mechanism. Background Technology

[0002] Fins and flat tubes are the core components of a radiator for heat dissipation. Currently, most radiators on the market use fins mounted on the outside of the flat tubes. However, to further improve heat dissipation, some radiators have also adopted an internal fin design, where the fins are inserted into the flat tubes. Because the adoption rate of internal fin radiators is still relatively low, most fin and flat tube assembly machines on the market are designed for externally finned radiators. Internally finned radiators are currently mostly assembled manually, especially the step of inserting the fins into the flat tubes, which significantly limits the production capacity of internally finned radiators. Summary of the Invention

[0003] To solve the above-mentioned technical problems, this invention proposes a highly automated radiator fin-flat tube assembly mechanism.

[0004] The radiator fin-flat tube assembly mechanism includes a frame, an assembly platform, a flat tube feeding assembly, a fin feeding assembly, and a fin pushing assembly.

[0005] The assembly platform provides a station for assembling fins and flat tubes, and along this station are a fin feed end, a flat tube feed end, and an assembly discharge end. The fin feed end and the flat tube feed end are perpendicular, and the flat tube feed end and the assembly discharge end are parallel and opposite to each other. The fin feed end is located between the flat tube feed end and the assembly discharge end, and can introduce fins into the station where flat tubes have already been placed.

[0006] The flat tube feeding assembly connects to the flat tube feeding end, and the flat tube enters the assembly platform in an orientation parallel to the flat tube conveying direction. The fin feeding assembly connects to the fin feeding end, and the fins enter the assembly platform in an orientation parallel to the flat tube.

[0007] The fin pusher assembly is installed between the assembly platform and the fin feeding assembly, and is provided with a pusher plate that reciprocates along the fin conveying direction. The pusher plate pushes the fins located on the fin feeding assembly so that they enter the assembly platform through the fin feeding end and are inserted into the flat tube on the assembly platform to realize the assembly between the fins and the flat tube.

[0008] This invention provides a radiator fin-flat tube assembly mechanism with an assembly platform featuring a fin feed end, a flat tube feed end, and an assembly discharge end. A flat tube feed assembly, a fin feed assembly, and a fin pushing assembly are arranged along the assembly platform. The flat tube is transported to the assembly station on the assembly platform, and the fin pushing assembly then pushes the fins fed through the fin feed assembly into the flat tube, completing the assembly. This radiator fin-flat tube assembly mechanism is highly automated and can quickly and systematically complete the assembly of fins and flat tubes, thereby improving the radiator assembly speed.

[0009] Preferably, the flat tube feeding assembly includes a pair of flat tube feeding belts symmetrically arranged on both sides of the assembly platform, driven by pulleys, and both flat tube feeding belts are driven by the same motor. The flat tube feeding end is located between the two flat tube feeding belts, and the fin feeding end of the assembly platform is close to one of the flat tube feeding belts. The flat tube feeding assembly can feed flat tubes into the assembly platform and also can send the assembled flat tubes out of the assembly platform.

[0010] Preferably, the flat tube feeding belt is provided with a flat tube limiting groove to restrict a single flat tube, and the two flat tube feeding belts restrict the two ends of the flat tube through the flat tube limiting groove, thereby positioning the flat tube.

[0011] Preferably, to enable the assembly mechanism to feed flat tubes of different lengths, the flat tube feeding assembly further includes two adjusting seats. The two adjusting seats are located on both sides of the assembly platform and are slidably mounted on the frame via sliders and rails, respectively. They are driven by the same motor via a lead screw and nut, allowing them to simultaneously move closer to or further away from the assembly platform. The two feeding belts are respectively mounted on the two adjusting seats and can adjust their spacing accordingly.

[0012] Preferably, the fin feeding assembly includes a fin feeding belt, which is installed perpendicular to the fin feeding end and driven by a motor via a pulley.

[0013] Preferably, the fin pushing assembly includes a pushing base, a pushing translation drive, and a pushing lifting drive. The frame has a crossbeam at the top of the fin feeding assembly, the fin pushing assembly, and the assembly platform. The pushing base is mounted on the bottom of the crossbeam via the pushing translation drive and reciprocates along the fin's moving direction. The pushing lifting drive is mounted on the pushing base and drives the pushing plate to reciprocate up and down, moving it away from or towards the conveying track of the fin feeding assembly. This allows the fin to be lowered and pushed when assembly is required, and after pushing and assembling the fin, it rises to avoid obstructing the entry of the next fin.

[0014] Preferably, to prevent the fins from warping or shifting during assembly, and to prevent the flat tube from deviating from its position, the fin pushing assembly further includes a fin pressing component and a flat tube pressing component, both of which include a pressing and lifting drive component and a pressing seat. The fin pressing component is installed near the fin feed end and can limit the movement of the fin, allowing it to move only in the conveying direction. The flat tube pressing component is installed on the top of the assembly platform via a crossbeam and can press down on the flat tube.

[0015] Preferably, the jacking and translating drive component adopts a drive structure of motor driving belt and pulley, while the jacking and lifting drive component and the pressing and lifting drive component both adopt a cylinder drive structure, which is simple in structure.

[0016] Preferably, the device further includes a flat tube feeding assembly, which comprises a movable storage seat, a discharge drive, and a baffle plate. The movable storage seat is movably disposed at the top of the feed end of the conveyor belt of the flat tube feeding assembly and is driven by the discharge drive to reciprocate along the direction of flat tube conveying. There are two movable storage seats, arranged parallel to each other on both sides of the flat tube feeding belt, with several vertically penetrating storage troughs on opposite sides. The baffle plate is installed between the flat tube feeding belt and the movable storage seat, blocking the bottom opening of the storage troughs. The discharge drive drives the movable storage seat to move gradually, and each storage trough gradually shifts away from the baffle plate, thereby enabling the flat tubes stacked in the storage troughs to be fed one by one onto the conveyor belt of the flat tube feeding assembly.

[0017] Preferably, to straighten the assembled flat tube, a straightening component is also included. The feeding end of the straightening component is connected to the assembly discharge end of the assembly platform, and includes an output track, at least two sets of clamping rollers, an output drive component, and an output push plate. The output track receives the flat tube output from the assembly discharge end. The clamping rollers are installed at intervals along the output track, dividing the output track into several segments. The flat tube output from the assembly mechanism discharge end is straightened by the clamping rollers and pushed out of the output track. The output drive component is installed on the top of the assembly discharge end and drives the output push plate to push the flat tube on the assembly discharge end into the output track and the clamping rollers.

[0018] As can be seen from the above description of the present invention, the present invention has the following beneficial effects:

[0019] 1. This invention provides an assembly platform with a finned feed end, a flat tube feed end, and an assembly discharge end. A flat tube feed assembly, a finned feed assembly, and a fin pushing assembly are arranged along the assembly platform. The flat tube is transported to the assembly station on the assembly platform, and the fin pushing assembly pushes the fins fed through the finned feed assembly into the flat tube, completing the assembly. The radiator fin-flat tube assembly mechanism provided by this invention has a high degree of automation and can quickly and orderly complete the assembly between the fins and the flat tube, thereby improving the radiator assembly speed.

[0020] 2. The flat tube feeding assembly adopts an adjustable spacing structure, making it suitable for flat tubes of various lengths and specifications;

[0021] 3. The fin pushing assembly also includes a fin pressing component and a flat tube pressing component, which can prevent the fins from tilting or shifting during assembly, and also prevent the flat tube from deviating from its position.

Detailed Implementation

[0034] To make the technical problems, solutions, and beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the invention.

[0035] Please see Figures 1 to 7 The radiator fin-flat tube assembly mechanism includes a frame 1, an assembly platform 2, a flat tube feeding assembly 3, a fin feeding assembly 4, and a fin pushing assembly 5.

[0036] The assembly platform 2 provides a station for assembling fins and flat tubes, and a fin feed end 21, a flat tube feed end 22, and an assembly discharge end 23 are provided along the station. The fin feed end 21 and the flat tube feed end 22 are perpendicular, and the flat tube feed end 22 and the assembly discharge end 23 are parallel and opposite to each other. The fin feed end 21 is located between the flat tube feed end 22 and the assembly discharge end 23, and can introduce fins into the station where flat tubes have already been placed.

[0037] The flat tube feeding assembly 3 is connected to the flat tube feeding end 22, and the flat tube enters the assembly platform 2 in an attitude parallel to the flat tube conveying direction. The discharge end of the fin feeding assembly 4 is connected to the fin feeding end 21, and the fins enter the assembly platform 2 in an attitude parallel to the flat tube.

[0038] In one embodiment, the flat tube feeding assembly 3 includes a pair of flat tube feeding belts 31, symmetrically arranged on both sides of the assembly platform 2, driven by pulleys, and both flat tube feeding belts 31 are driven by the same motor. The flat tube feeding end 22 is located between the two flat tube feeding belts 31, and the fin feeding end 21 of the assembly platform 2 is close to one side of the flat tube feeding belt 31. The flat tube feeding assembly 3 can feed flat tubes into the assembly platform 2 and also can send assembled flat tubes out of the assembly platform 2.

[0039] To improve the alignment of the fins and flat tubes, the flat tube feed belt 31 is provided with a flat tube limiting groove 311 for placing a single flat tube. The two flat tube feed belts 31 restrict the two ends of the flat tube through the flat tube limiting groove 311, thereby positioning the flat tube.

[0040] Based on the above embodiments, in another embodiment, to enable the assembly mechanism to transport flat tubes of different lengths, the flat tube feeding assembly 3 further includes two adjusting seats 32. The two adjusting seats 32 are disposed on both sides of the assembly platform 2 and are slidably mounted on the frame 1 via sliders and rails, respectively. They are driven by the same motor via a lead screw and nut, allowing them to simultaneously move closer to or further away from the assembly platform 2. The two feeding belts are respectively mounted on the two adjusting seats 32, and their spacing can be adjusted accordingly.

[0041] In one embodiment, the fin feeding assembly 4 includes a fin feeding belt 41, which is installed perpendicular to the fin feeding end 21 and driven by a motor via a pulley.

[0042] The fin pusher assembly 5 is installed between the assembly platform 2 and the fin feeding assembly 4, and is provided with a pusher plate 51 that reciprocates along the fin conveying direction. The pusher plate 51 pushes the fins located on the flat tube feeding assembly 3 so that they enter the assembly platform 2 through the fin feeding end 21 and are inserted into the flat tube on the assembly platform 2, thereby realizing the assembly between the fins and the flat tube.

[0043] In one embodiment, the fin pushing assembly 5 includes a pushing base 52, a pushing translation drive 53, and a pushing lifting drive 54. The frame 1 has a crossbeam 11 at the top of the fin feeding assembly 4, the fin pushing assembly 5, and the assembly platform 2. The pushing base 52 is mounted on the bottom of the crossbeam 11 via the pushing translation drive 53 and reciprocates along the fin's moving direction. The pushing lifting drive 54 is mounted on the pushing base 52 and drives the pushing plate 51 to move up and down reciprocally to move away from or near the conveying track of the fin feeding assembly 4. This allows the plate to descend and push the fins when assembly is required, and after pushing and assembling the fins, it can rise to avoid blocking the entry of the next fin.

[0044] In another embodiment, to prevent the fins from warping or shifting during assembly, and to prevent the flat tube from deviating from its position, the fin pushing assembly 5 further includes a fin pressing component 55 and a flat tube pressing component 56, both of which include a pressing and lifting drive component and a pressing seat. The fin pressing component 55 is installed near the fin feed end 21 and can limit the movement of the fins, allowing them to move only in the conveying direction. The flat tube pressing component 56 is installed on the top of the assembly platform 2 via a crossbeam 11 and can press down the flat tube.

[0045] Preferably, the push-and-translate drive 53 adopts a drive structure driven by a motor, belt, and pulley, while the push-and-lift drive 54 and the press-and-lift drive both adopt a cylinder drive structure, which is simple in structure.

[0046] Based on the above embodiments, in one embodiment, a flat tube feeding assembly 6 is further included. The flat tube feeding assembly 6 includes a movable storage seat 61, a discharge drive 62, and a baffle plate 63. The movable storage seat 61 is movably disposed at the top of the feed end of the conveyor belt of the flat tube feeding assembly 3, and is driven by the discharge drive 62 to reciprocate along the direction of flat tube conveying. There are two movable storage seats 61, which are arranged parallel to each other on both sides of the flat tube feeding belt, and each opposite side has a plurality of vertically penetrating storage troughs 611. The baffle plate 63 is installed between the flat tube feeding belt and the movable storage seat 61, and blocks the bottom opening of the storage trough 611. The discharge drive 62 drives the movable storage seat 61 to move gradually, and each of the storage troughs 611 and the baffle plate 63 are gradually staggered, so that the flat tubes stacked in the storage troughs 611 can be fed one by one onto the conveyor belt of the flat tube feeding assembly 3.

[0047] Based on the above embodiments, in order to straighten the assembled flat tubes, one embodiment further includes a straightening component 7. The feeding end of the straightening component 7 is connected to the assembly discharge end 23 of the assembly platform 2, and includes an output track 71, at least two sets of clamping rollers 72, an output drive component 73, and an output push plate 74. The output track 71 receives the flat tubes output from the assembly discharge end 23. The clamping rollers 72 are installed at intervals along the output track 71, dividing the output track 71 into several segments. The flat tubes output from the assembly mechanism discharge end are straightened by the clamping rollers 72 and pushed out of the output track 71. The output drive component 73 is installed on the top of the assembly discharge end 23 and drives the output push plate 74 to push the flat tubes on the assembly discharge end 23 into the output track 71 and the clamping rollers 72.

[0048] When the radiator fin-flat tube assembly mechanism provided by the present invention is working, the flat tube enters the assembly platform 2 from the flat tube feeding end 22 through the flat tube feeding assembly 3, while the fins are transported to the fin feeding end 21 of the assembly platform 2 through the fin feeding assembly 4, and then pushed by the fin pushing assembly 5, so that the fins enter the assembly platform 2 and at the same time enter the flat tube on the assembly platform 2, thereby realizing the assembly of the flat tube and the fins.

[0049] This invention provides an assembly platform 2 with a finned feed end 21, a flat tube feed end 22, and an assembly discharge end 23. A flat tube feed assembly 3, a finned feed assembly 4, and a fin pushing assembly 5 are arranged along the assembly platform 2. This allows the flat tube to be transported to the assembly station on the assembly platform 2. The fin pushing assembly 5 then pushes the fins fed through the finned feed assembly 4 into the flat tube, completing the assembly. The radiator fin-flat tube assembly mechanism provided by this invention has a high degree of automation and can quickly and orderly complete the assembly between the fins and the flat tube, thereby improving the radiator assembly speed.

[0050] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
