Technical Field

[0001] The invention relates to the field of processing and manufacturing of microchannel flat tube heat exchangers, and in particular to a fin flat tube press-fitting device. Background Art

[0002] The combined core of fins and flat tubes is one of the core components of the microchannel all-aluminum flat tube heat exchanger. Before installation, the stamped fins need to be pressed onto the microchannel flat tubes. Taking the assembly process of comb-shaped fins and flat tubes arranged in mirror symmetry as an example, the specific procedures are as follows: ① The stamped fins are separated and transported to the transfer station; ② The separated fins are transferred to the fin feeding device in turn; ③ The flat tubes are clamped and fed; ④ The fin rows are clamped, gathered and pressed onto the flat tubes.

[0003] In the above process ②, since the fin rows arranged in mirror symmetry are in opposite directions before being transported to the fin feeding device after separation, the fin rows cannot be uniformly stacked. Therefore, the directions of the fin rows need to be adjusted to be uniform by manual or other equipment before feeding, which reduces the pressing efficiency of the fin flat tube. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a fin flat tube press-fitting device, which has the advantage of being able to synchronously adjust the orientation of the fin row before press-fitting and feeding, thereby improving the press-fitting efficiency of the fin flat tube.

Among them, the fin column from the transfer station can be transported to the fin loading assembly by reciprocating the fin adjustment seat along the conveying guide rail by the horizontal moving seat, and the direction of the fin column can be synchronously adjusted during the conveying process by setting the fin adjustment seat to be rotatable in the horizontal plane, so that the direction of the fin column entering the fin pressing assembly is arranged in the same direction, so as to facilitate the subsequent stacking and collection of the fin columns, thereby improving the pressing efficiency of the fin flat tube.

[0044] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.

[0045] Embodiment 1:

[0046] The present invention provides a fin flat tube press-fitting device, which aims to solve the problem in the prior art that the direction of the feeding fin is not easy to adjust. The press-fitting device can not only realize the synchronous adjustment of the direction or orientation of the fin row during the feeding process, so as to facilitate the subsequent lamination of the fin row and the assembly between the fin row and the flat tube, but also the device occupies a small space during operation, which is convenient for the overall intensive design and miniaturized design. Figure 1 As shown, the fins described in this embodiment are comb-shaped, and a snap-fitting groove on the flat tube is formed between two adjacent comb teeth. The fin has a front side and a back side. A plurality of fins (fin rows) arranged in the same direction, that is, the front side or the back side is facing the pressing direction or arranged in the pressing direction, are clamped and stacked to form a fin row module with a certain density. Finally, the fins are pressed onto the flat tube in the form of a fin row module.

[0047] like Figure 2-3As shown, in this embodiment, the press-fitting equipment comprises: a frame 1, a pre-pressing feeding device 2, a fin loading assembly 3 and a fin pressing assembly 5. The frame 1 comprises a main frame, a front conveying frame body located at the front side of the main frame and a rear conveying frame body located at the rear side of the main frame. A flat tube positioning area is provided below the main frame. The fin pressing assembly 5 is connected to the main frame and is used to clamp and stack the fin rows and press-fit the stacked fin rows onto the positioned flat tubes. The fin loading assembly 3 is used to supply the fin pressing assembly 5 with the fins. For the stacked fin rows arranged in the same direction, the pre-pressing feeding device 2 is connected to the front conveying frame of the frame 1, and the pre-pressing feeding device 2 specifically includes a conveying guide rail 21, a horizontal movable seat 221 and a fin adjustment seat 22, wherein the conveying guide rail 21 is arranged on the front conveying frame in a manner extending toward the pressing direction; the horizontal movable seat 221 is connected to the conveying guide rail 21, and the fin adjustment seat 22 is arranged on the horizontal movable seat 221 in a manner capable of rotating in a horizontal plane, for receiving and adjusting the direction of the fin row.

[0048] In this embodiment, after the separated fins are conveyed to the transfer station, the fin array of the transfer station is received by the pre-pressing feeding device 2 and conveyed to the fin loading assembly 3, and the fin loading assembly 3 transfers the fin array on the pre-pressing feeding device 2 to the clamping component of the fin pressing assembly 5, and the fin pressing assembly 5 clamps and stacks the fin arrays arranged in the same direction to form a fin array module with a set density, and the fin array module is pressed onto the positioned flat tube to complete the fin and flat tube connection. Press-fitting, specifically, by reciprocating the fin adjustment seat 22 along the conveying guide rail 21 through the horizontal moving seat 221, the fin row from the transfer station can be continuously conveyed to the fin loading assembly 3. Since the fin adjustment seat 22 is configured to be rotatable in the horizontal plane, the direction of the fin row can be synchronously adjusted during the conveying process, so that the several fin rows entering the fin press-fitting assembly 5 are arranged in the same direction, thereby facilitating the subsequent stacking and collection of the fin rows, thereby improving the press-fitting efficiency of the fin flat tube.

[0049] Specifically, the frame 1 has two parallel and oppositely arranged conveying rails 21, wherein each of the conveying rails 21 is provided with a horizontal moving seat 221, and the two horizontal moving seats 221 are provided with a first lifting rail 222, a longitudinal moving seat 223 is connected between the two first lifting rails 222, and the fin adjustment seat 22 is provided on the longitudinal moving seat 223. Further, a driving turntable 224 is provided on the longitudinal moving seat 223, and the fin adjustment seat 22 is installed on the driving turntable 224, and the rotation angle range of the driving turntable 224 is α≥180°. Here, the driving turntable 224 can be a hydraulic turntable or a servo rotating platform, which is not limited here.

[0050] Here, the fin adjustment seat 22 includes a rectangular mounting seat body 22a placed horizontally on the driving turntable 224 and a plurality of fin guide blades 22b. The mounting seat body 22a is arranged on the horizontal movable seat 221, and the plurality of fin guide blades 22b are arranged on the mounting seat body 22a in a spaced-apart and parallel manner. During the feeding process, the fin can be buckled on the guide blade 22b in a standing posture through the snap-fit ​​groove between the comb teeth.

[0051] The structure of the rotatable fin adjustment seat 22 can flexibly adjust the orientation of the fin row before entering the fin pressing assembly, and has better use effects in multiple application scenarios. For example, when the transfer station needs to uniformly transport two fin rows with different orientations, the horizontal movable seat 221 can be moved to the transfer station platform first. Assuming that one of the fin rows is received first, the fin adjustment seat 22 is lifted to a certain height by the longitudinal movable seat 223 to avoid the surrounding equipment structure, and the drive turntable 224 drives the fin adjustment seat 22 to rotate 180 degrees. At this time, the orientation of the fin row is adjusted, that is, from the original front side facing the pressing direction to the back side facing the pressing direction, or vice versa. Then the longitudinal movable seat 223 drives the fin adjustment seat 22 to move to the station of another fin row to receive the fin row. At this time, the two received fin rows are in the same orientation, which is convenient for the subsequent loading and stacking steps. For another example, when assembling a parallel flow heat exchanger core with the feature of changing the refrigerant flow direction, the installation orientation of the fins on the flat tubes at different locations may be different. In this case, it is necessary to adjust the orientation of the fin row before pressing and loading. The above structure can realize fully automated assembly of the flat tubes and fins, thereby improving the core processing efficiency.

[0052] refer to Figures 2 to 5 As shown, in this embodiment, the fin loading assembly 3 includes a lifting mounting frame 33, a mobile loading frame 31 and a first screw driving mechanism 34. The lifting mounting frame 33 is connected to the frame 1 and is located above the flat tube positioning area. Specifically, two second lifting guide rails 32 arranged opposite to each other are provided on both sides of the main frame, and the lifting mounting frame 33 is connected between the two second lifting guide rails 32. The mobile loading frame 31 is movably connected to the lifting mounting frame 33, and the first screw driving mechanism 34 is used to drive the mobile loading frame 31 to move back and forth. Figure 3 , 4 As shown in Figure 5, the movable loading rack 31 includes an L-shaped movable frame and a plurality of material receiving knife plates connected to the lower part of the movable frame, wherein the movable frame is connected to the lifting mounting frame 33 through a frame guide rail, the arrangement direction of the frame guide rail is parallel to the feeding direction, and the plurality of material receiving knife plates are connected to the end of the movable frame in an interval and parallel manner, and the material receiving knife plate and the guide knife plate 22b on the fin adjustment seat 22 are staggered with each other in the horizontal direction, and the first screw driving mechanism 34 is connected to the movable frame to drive the movable frame to reciprocate on the frame guide rail.

[0053] In this embodiment, the fin press assembly 5 includes a press cylinder 51, a pressure seat plate 52 and a fin clamping mechanism 53. One end of the press cylinder 51 is fixed on the frame 1, and its piston rod passes through the lifting mounting frame 33. The pressure seat plate 52 is connected to the lower end of the piston rod of the press cylinder 51, and the fin clamping mechanism 53 is arranged at the lower part of the pressure seat plate 52. Here, the fin clamping mechanism 53 specifically includes a fixed baffle 531, a movable baffle 532 and a second screw driving mechanism 533. The fixed baffle 531 is arranged at the lower part of the pressure seat plate 52 in a direction perpendicular to the conveying direction or feeding direction of the fin column. The movable baffle 532 is arranged opposite to and parallel to the fixed baffle 531. The upper part of the movable baffle 532 is slidably connected to the lower part of the pressure seat plate 52. The second screw driving mechanism 533 is used to drive the movable baffle 532 to move relative to the fixed baffle 531 to clamp the fin column.

[0054] It should be noted that the pressure seat plate 52 and the lifting mounting frame 33 can move relative to each other in the longitudinal direction. When the fins need to be transferred to the fin clamping mechanism 53, the first screw driving mechanism 34 can first drive the movable loading frame 31 to move toward the fin adjustment seat 22, and the lifting mounting frame 33 drives the movable loading frame 31 to move upward, so that the material receiving knife plate on the movable loading frame 31 passes over the fin row on the fin adjustment seat 22, and then the lifting mounting frame 33 drives the movable loading frame 31 to move downward, so that the material receiving knife plate on the movable loading frame 31 moves in the longitudinal direction. The first screw driving mechanism 34 drives the movable loading rack 31 to move backward until the material receiving blade reaches the bottom of the fin row, and the lifting and lowering mounting frame 33 drives the movable loading rack 31 to move upward. At this time, the fin row falls on the material receiving blade, and the first screw driving mechanism 34 drives the movable loading rack 31 to continue to move backward. The lifting and lowering mounting frame 33 drives the movable loading rack 31 to move downward. The first screw driving mechanism 34 drives the movable loading rack 31 to load materials and moves to the position where the material receiving blade is located below the fin clamping mechanism 53. At this time, the second screw driving mechanism 533 drives the movable baffle 532 to move, clamp and stack the fins on the material receiving blade until a fin row module or module with a set density is formed, and the first screw driving mechanism 34 drives the movable loading rack 31 to move forward, so that the material receiving blade exits the fin clamping mechanism 53.

[0055] refer to Figure 2 , 3As shown in FIG6 , in this embodiment, a flat tube feeding device 4 for conveying the flat tubes to the flat tube positioning area is further included. Specifically, the flat tube feeding device 4 includes a flat tube tray 41 and a flat tube clamping mechanism 42 disposed on the flat tube tray 41, wherein the flat tube tray 41 is movably connected to the frame 1. Here, the flat tube clamping mechanism 42 includes a plurality of mounting grooves 421 and a plurality of support blocks 422, and the plurality of mounting grooves 421 are disposed on the flat tube tray 41 in a manner of being spaced apart along a set direction, as shown in FIG6 . Figure 2 As shown, a plurality of rectangular mounting grooves 421 are arranged at intervals in the width direction of the pallet, and a plurality of support blocks 422 are connected to the mounting grooves 421 one by one, and the support blocks 422 are constructed to be able to float up and down in the corresponding mounting grooves 421. For example, a floating spring can be installed between the bottom of the support block 422 and the mounting groove, or other structures with buffering and floating effects in the prior art can be adopted, which will not be elaborated here. A clamping groove 423 for clamping the flat tube is formed between two adjacent support blocks 422. Preferably, since the flat tube has a certain length, in order to maintain the stability of the flat tube during installation or loading, a plurality of flat tube clamping mechanisms 42 are equidistantly and evenly arranged along the length direction of the flat tube, and the plurality of flat tube clamping mechanisms 42 act synchronously, so that the clamping and installation of the flat tube is more firm and stable.

[0056] In this embodiment, the rear conveying frame of the frame 1 is arranged vertically with the front conveying frame, and a pallet loading guide rail 411 is provided on the rear conveying frame. The flat tube pallet 41 is connected to the pallet loading guide rail 411 and can reciprocate along the pallet loading guide rail 411. A pallet conveying line 412 is also provided on the rear conveying frame. The flat tube and fin integrated core after press-fitting can be unloaded from the pallet conveying line 412, and the flat tube pallet 41 can be loaded from the pallet conveying line 412.

[0057] In this embodiment, during press-fitting, the flat tube tray 41 drives the clamped and installed flat tube to move to the flat tube positioning area, and the press-fitting cylinder 51 drives the pressure seat plate 52 to press-fit the stacked fin row onto the flat tube. During the press-fitting stage, the comb teeth of the fins can first contact the upper surface of the support block 422. As the pressure increases, the support block 422 gradually floats downward until the comb teeth of the fins drop to a set height. This structural setting can buffer the downward pressure on the fins, which can not only ensure that the fins are pressed into place, but also make the press-fitting process of the fins and the flat tubes more stable, preventing excessive pressure from damaging the surface of the fins or the flat tubes.

[0058] In summary, in the above embodiment, the fin adjustment seat 22 is reciprocated along the conveying guide rail 21 by the horizontal moving seat 221, so that the fin row from the transfer station can be conveyed to the fin loading assembly 3, and by setting the fin adjustment seat 22 to be rotatable in the horizontal plane, the direction of the fin row can be synchronously adjusted during the conveying process, so that the several fin rows entering the fin pressing assembly 3 are arranged in the same direction, thereby facilitating the stacking and collection of subsequent fin rows, thereby improving the pressing efficiency of the fin flat tube.
