Description

Technical Field

[0001] This invention relates to the technical field of microchannel heat exchanger core processing, and more particularly to a transverse fin assembly device and method, wherein the fin has a notch for inserting a flat tube. Background Technology

[0002] The metal fins in a flat-tube microchannel heat exchanger are typically formed from uncoiled metal strips through processes such as stamping, slitting, and cutting. During stamping, notches for mounting the flat tubes, openings for hot gas flow, and anti-foolproof protrusions distributed along the fin edges are formed on the fins. After inter-row slitting, the metal strips are divided into several metal strips of a predetermined width. Finally, after cutting along the length direction, the metal strips are formed into fins of a predetermined length to be assembled.

[0003] like Figure 9 As shown, in traditional technology, fins are aligned during stamping, meaning all fins are arranged with their front (convex surface) facing upwards and their notches facing the same side and aligned. This allows for simultaneous placement and pre-pressing of all fins after cutting and trimming. For example, a synchronous flipping mechanism can be used to flip all fins to a set angle, ensuring they face the same direction as the pre-pressing, facilitating subsequent assembly. However, this arrangement can easily generate stress at the comb-tooth area of ​​the fins during stamping, causing warping and deformation during transport. This not only hinders accurate positioning during transport but also easily damages the fins. To address this issue, such as... Figure 8 As shown, some existing technologies employ a symmetrical arrangement of fins, which can reduce the stress generated during stamping to a certain extent, thereby avoiding the aforementioned warping and deformation phenomena.

[0004] However, due to the symmetrical distribution of the fins, they cannot be synchronously arranged before pressing. Therefore, after the fins are cut and output, they need to undergo layer processing. That is, for each pair of symmetrically arranged fins, one column needs to be output to the upper layer and the other column to the lower layer. After the two columns are separated, the fins of each layer are uniformly arranged, transferred, pre-pressed, and finally stacked. Since the upper and lower layers of fins have different orientations after arrangement, the existing technology usually uses two different stacking structures to stack the fins of different layers. In order to enable the two stacking mechanisms to work synchronously, parallel transfer components and pre-pressing devices are also required to perform pre-pressing treatment on the fins.

[0005] In summary, it can be seen that the fins produced by the existing symmetrical arrangement method require two different sets of placement, pre-pressing and stacking structures after layering to complete the press-fitting of the fins and flat tubes. This results in high equipment costs and is not conducive to the intensification and miniaturization of the equipment. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a transverse fin assembly equipment and process. The use of this equipment and process can simplify the press-fit feeding structure for fin rows with different orientations after layering, and further reduce equipment cost and space occupied by the equipment while ensuring fin assembly efficiency.

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

[0008] A transverse fin assembly device, wherein one side of the fin has several comb teeth and a notch for installing a flat tube is formed between two adjacent comb teeth, and in the initial state, the fins are paired in pairs and connected by comb teeth and are distributed in a mirror-symmetrical manner in the same plane. The device is characterized by comprising: a layered conveying device for inputting paired fins and separating them into an upper fin column and a lower fin column for parallel transport; a vertical flipping device for receiving the upper or lower fin column and flipping it to a standing position, wherein the upper and lower fin columns face opposite directions after standing; and a pressing and feeding device, comprising: a frame; an upper pushing component for pushing the standing upper fin column from the vertical flipping device for centralized output; a lower pushing component for pushing the standing lower fin column from the vertical flipping device for centralized output; and a rotating receiving component for receiving the centralized output fin column and conveying it to a pressing and processing line.

[0009] Compared with existing technologies, this transverse fin assembly equipment has the following advantages:

[0010] This equipment incorporates a press-fit feeding device with an adjustable angle within a plane, positioned between the press-fit processing line and the layered conveying device. After being attached to the upper fin row, the orientation of the fin row can be adjusted by rotation to align with the orientation of the next fin row to be attached to the receiving stand. This allows for unified attachment and conveying of each layer of fins after layered output to the press-fit processing line. This simplifies the feeding devices and structures for fin rows with different orientations before press-fitting, ensures efficient transfer and assembly of fin rows, and facilitates a compact, integrated design.

[0011] To optimize the above technical solution, the following technical measures were also adopted:

[0012] In a preferred embodiment, the rotating receiving component includes: a feeding moving seat connected to the frame; a lifting adjustment seat connected to the feeding moving seat; and a receiving upright plate seat rotatably connected to the lifting adjustment seat in a horizontal plane.

[0013] In a preferred embodiment, the layered conveying device includes:

[0014] Separation component for separating the paired fins;

[0015] The upper conveyor line used to transport the upper fin array and the upper conveyor rollers located behind the upper conveyor line;

[0016] The lower conveyor line used to transport the lower fin array and the lower conveyor rollers located behind the lower conveyor line.

[0017] In a preferred embodiment, the vertical flipping device includes:

[0018] An upper-layer flipping mechanism for synchronously adjusting the attitude of the upper fin row; and

[0019] Lower flipping mechanism for synchronously adjusting the attitude of the lower fin row;

[0020] The upper flipping mechanism and the lower flipping mechanism have the same construction.

[0021] In a preferred embodiment, the flipping mechanism includes:

[0022] A linear lifting module is located below the corresponding conveyor roller; and

[0023] Multiple flip-up vertical plates are arranged at intervals and relatively parallel to each other on the upper part of the linear lifting module along the fin conveying direction;

[0024] The flipping plate is adapted to couple the notch of the fin row to restrict the fin row above the plate body. An avoidance groove is formed between two adjacent flipping plates. The comb teeth of the fin row can rotate downward in the corresponding avoidance groove and drive the fin row to flip vertically.

[0025] In a preferred embodiment, the upper pushing component is located above the upper conveying roller, and the upper pushing component includes:

[0026] Guide rails are provided on the frame in a manner extending toward a side perpendicular to the conveying direction of the conveyor rollers; and

[0027] A scraper assembly adapted to the guide rail and suitable for pushing the fin array on the vertically flipping plate to slide out from one end of the plate.

[0028] In a preferred embodiment, the rotating receiving component includes a pair of linear guide rails arranged opposite to each other and parallel to each other on the frame, each linear guide rail being provided with a feeding moving seat adapted thereto, and the lifting adjustment seat being disposed between the two feeding moving seats.

[0029] In a preferred embodiment, the pressing process line includes a pre-pressing collection device, a pre-pressing device, and a stacking device, wherein the pre-pressing collection device is movably coupled to the frame and is used to collect the fin rows from the receiving upright plate seat to the loading platform of the pre-pressing device.

[0030] In a preferred embodiment, the pre-pressing collection device includes:

[0031] Support cantilever, which is mounted on the frame via a slide rail slider; and

[0032] Multiple L-shaped vertical plates are arranged at one end of the supporting cantilever and are spaced apart along the width direction of the cantilever and are relatively parallel to each other.

[0033] The L-shaped vertical plate is offset from the vertical plate on the receiving vertical plate seat in the width direction, and the L-shaped vertical plate is configured to engage the notch of the fin row and restrict the fin row on the L-shaped vertical plate.

[0034] The present invention also discloses an assembly process for transversely inserted fins, which specifically includes the following steps:

[0035] 1) The fins are punched and output in the form of several pairs of fins in an initial state;

[0036] 2) The fin pairs in step 1 are synchronously separated to form an upper fin column and a lower fin column, wherein the comb teeth of the upper fin column are opposite to the comb teeth of the lower fin column.

[0037] 3) The upper and lower fin rows are conveyed to the corresponding conveyor rollers at the set positions. At this time, the notches of the upper and lower fin rows are opposite to the roller gaps of the corresponding conveyor rollers.

[0038] 4) Simultaneously flip the upper and lower fin rows from a horizontal position to a standing position;

[0039] 5) Push the upper fin array from the central assembly onto the receiving plate seat of the rotating receiving component;

[0040] 6) Move the receiving plate seat upwards so that it is longitudinally offset from the components of the assembly equipment and rotate the receiving plate seat to 180° in the plane. At this time, the upper fin row and the lower fin row on the receiving plate seat face the same direction.

[0041] 7) Move the receiving plate seat downwards and push the lower fin array from the central position onto the receiving plate seat of the rotating receiving component;

[0042] 8) Move the pressing and feeding device to uniformly transport the fin array on the receiving upright plate to the pressing and processing line.

[0043] Through the above assembly process, after the rotating feeding component is placed on the upper fin row, the receiving plate seat is slightly lifted to offset it from the other components of the assembly equipment. Then, the receiving plate seat rotates 180° in the plane to align with the orientation of the lower fin row. This allows the lower fin row to be pushed onto the receiving plate seat as well. Essentially, the receiving plate seat reciprocates once to receive both the upper and lower layers of material while maintaining consistent orientation, facilitating subsequent unified pressing. This process ensures efficiency in fin row placement, conveying, and pressing, while reducing the need for parallel conveyor lines. The equipment is simple to operate and has a reliable structure.

[0059] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, features in the following embodiments can be combined with each other.

[0060] Example 1:

[0061] Please see Figure 1 This invention first provides a transverse fin assembly device, which aims to solve the technical problem that the pressing and feeding device or structure of the symmetrically distributed fins after layering in the existing flat tube fin assembly equipment is too complicated or redundant. It not only simplifies the pressing and feeding structure for double-layer fin rows with different orientations, but also further reduces the equipment cost and the space occupied by the equipment, which is conducive to intensive and integrated design.

[0062] refer to Figures 2 to 4 As shown, in this horizontal fin assembly device, one side of the fin has several comb teeth 61, and a notch 62 for installing a flat tube is formed between two adjacent comb teeth 61. The fin is also provided with a protrusion 63. In this embodiment, the side with the protrusion 63 is defined as the front side of the fin row. Figure 8 As shown, in the initial state, the fins 6 are in pairs and the two fins in each pair are connected by comb teeth 61 and are distributed in a mirror-symmetric manner in the same plane. The initial state is the state of the fins output after being punched by the punching device 1.

[0063] Specifically, the equipment includes a layered conveying device 2, a vertical flipping device 3, and a pressing and feeding device 4. The layered conveying device 2 is used to input paired fins and separate them into an upper fin column and a lower fin column for parallel transport. It should be noted that the upper fin column consists of fin columns 6 on the same side of several fin pairs, with the same orientation and consistent comb tooth extension direction. Similarly, the lower fin column also has the same orientation and comb tooth extension direction. Furthermore, the layered conveying device 2 includes: a separating component 21 for separating the paired fins, an upper conveyor line 22 for conveying the upper fin column and an upper conveyor roller 23 located behind the upper conveyor line 22, and a lower conveyor line for conveying the lower fin column and a lower conveyor roller located behind the lower conveyor line. Here, the upper conveyor line and upper conveyor roller can have the same structure as the lower conveyor line and lower conveyor roller, and are arranged relatively parallel to each other on the frame.

[0064] like Figure 5 and 6As shown, in this embodiment, the vertical flipping device 3 is used to receive the upper or lower fin array and flip it to a standing position, wherein the upper and lower fin arrays face opposite directions after standing. Specifically, the vertical flipping device 3 includes an upper flipping mechanism 31 for synchronously adjusting the posture of the upper fin array and a lower flipping mechanism 32 for synchronously adjusting the posture of the lower fin array, wherein the upper flipping mechanism 31 and the lower flipping mechanism 32 can adopt the same structure. Taking the upper flipping mechanism 31 as an example, the flipping mechanism includes a linear lifting cylinder 311 located below the corresponding conveying roller, and a plurality of flipping uprights 312 arranged at intervals and relatively parallel to each other on the upper part of the linear lifting cylinder 311. An avoidance groove 313 is formed between two adjacent flipping uprights 312. When the flipping mechanism is working, the fin row 6 carried on the conveyor roller has been positioned, and it must be ensured that the notch 62 on the fin row 6 is aligned with the roller gap of the corresponding conveyor roller. The linear lifting cylinder 311 lifts the flipping plate 312 upward. The upper edge of the flipping plate 312 can pass through the roller gap and be supported below the notch 62 of the fin row 6. The comb teeth 61 of the fin row 6 rotate downward due to gravity in the corresponding avoidance groove 313, causing the fin row 6 to flip vertically. Figure 6 The image shows a row of fins in an upright position.

[0065] In this embodiment, the pressing and feeding device 4 includes: a frame 41, an upper pushing component 42, a lower pushing component 43, and a rotating receiving component 44. Here, the arrangement direction of the frame 41 is perpendicular to the conveying direction of the conveying roller. The upper pushing component 42 is used to push the upright upper fin array 6 to be concentrated and output from the vertical flipping device 3. The lower pushing component 43 is used to push the upright lower fin array 6 to be concentrated and output from the vertical flipping device 3. The rotating receiving component 44 is used to receive the concentrated output fin array 6 and convey it to the pressing processing line 5. Further, the upper pushing component 42 is located above the upper conveying roller 23, and the upper pushing component 42 includes a guide rail 421 and a scraper assembly 422. The guide rail 421 is arranged on the frame 41 in a manner extending toward a side perpendicular to the conveying direction of the conveying roller. The scraper assembly 422 is adapted to the guide rail 421 and is suitable for pushing the fin array 6 on the vertical flipping plate 312 to slide out from one end of the plate. Here, the scraper assembly 422 includes a movable cantilever that can slide along the guide rail 421 and a scraper that is vertically and retractably connected below the movable cantilever, such as... Figure 6As shown, the lower part of the scraper is provided with a sliding fastening part. When it is necessary to push the fin row 6 on the vertical flip plate 312 to disengage, the lifting drive on the movable cantilever can drive the scraper to move downward until the sliding fastening part is fastened to one end of the flip plate 312. Then, the movable cantilever is controlled to move along the flip plate 312. The direction of arrow A in the figure shows the direction of movement of the scraper, while the direction of arrow C shows the direction of movement of the flip plate 312. The scraper moves to push the fin row 6 to disengage from the flip plate 312.

[0066] In this embodiment, the rotating receiving component 44 includes: a feeding movable seat 442 connected to the frame 41; a lifting adjustment seat 443 connected to the feeding movable seat 442; and a receiving upright plate seat 444 rotatably connected to the lifting adjustment seat 443 in a horizontal plane. Specifically, the rotating receiving component 44 includes a pair of linear guide rails 441 arranged parallel to each other on the frame 41, each linear guide rail 441 being provided with a matching feeding movable seat 442, such as... Figure 4 As shown, the feeding moving seat 442 is inverted L-shaped, and the lifting adjustment seat 443 is disposed between the two feeding moving seats 442. Here, the lifting adjustment seat 443 can be connected between the two feeding moving seats 442 by means of lifting slide rail and slider cooperation, or other lifting and adjusting structures can be adopted. The receiving upright seat 444 includes a body 444a and a number of side uprights 444b that are equally spaced and arranged in parallel on the body 444a. After the fin row 6 is released from the vertical flip upright, it can slide directly onto the receiving upright seat 444 in a standing posture, and at this time, the notch 62 of the fin row 6 is engaged with the corresponding side upright 444b. Here, a rotary drive component 445 is also provided on the lifting adjustment seat 443. It can be a servo motor or a rotary cylinder, etc. The bottom of the receiving upright seat 444 can be directly fixed on the rotary drive component 445. Preferably, the rotary drive component 445 is connected to the lifting adjustment seat 443 through a bearing, and a turntable is provided on its output shaft. The receiving upright seat 444 is fixed on the turntable, so that the seat body is more stable when rotating. Preferably, a transition upright seat 7 is also provided on the frame 41. The transition upright seat 7 is located between the pushing component and the rotary receiving component 44, and the height of the upright on the transition upright seat 7 can be consistent with the height of the vertical flipping upright when it is lifted. Thus, the fin array that comes off the flipping upright can temporarily stay on the transition upright seat 7, so that the loading and unloading process of the fin array 6 between the two devices can be stably connected.

[0067] like Figure 7As shown, the curved arrows indicate the state of the upper fin array 6 rotating along with the rotating receiving component 44 during rotation, i.e., the state when the orientation of the fin array 6 is adjusted. Through the arrangement of the rotating receiving component 44, the receiving stand 444, after being placed onto the upper fin array 6, can adjust the orientation of the fin array 6 by rotation, making it consistent with the orientation of the lower fin array 6 that will be placed onto the receiving stand 444. This achieves unified placement and unified conveying of each layer of fin array 6 after layered output to the pressing processing line 5.

[0068] In this embodiment, the pressing processing line 5 includes a pre-pressing collection device 51, a pre-pressing device 52, and a stacking device 53. The pre-pressing collection device 51 is movably coupled to the frame 41 and is used to collect the fin array 6 from the receiving upright plate seat 444 to the loading platform of the pre-pressing device 52. Specifically, the pre-pressing collection device 51 includes a support cantilever and a plurality of L-shaped upright plates. The support cantilever is mounted on the frame 41 via a slide rail slider. The plurality of L-shaped upright plates are disposed at one end of the support cantilever and are spaced apart along the width direction of the cantilever and arranged in a relatively parallel manner. The L-shaped upright plates are offset from the upright plates on the receiving upright plate seat 444 in the width direction, and the L-shaped upright plates are configured to engage the notch portion 62 of the fin array 6 and constrain the fin array 6 on the L-shaped upright plate. The pre-pressing collection device 51 collects and integrates the finned array 6 after placement onto the loading platform of the pre-pressing device 52. The pre-pressing device 52 first performs pre-pressing treatment, and finally sends the pre-pressed finned array 6 to the stacking device 53 to complete the stacking assembly with the flat tube.

[0069] This embodiment also discloses an assembly process for transversely inserted fins, which specifically includes the following steps:

[0070] 1) such as Figure 8 As shown, the fins are punched and output in the form of several pairs of fins in an initial state;

[0071] 2) The fin pairs in step 1 are synchronously separated to form an upper fin row 6 and a lower fin row 6, wherein the comb teeth 61 of the upper fin row 6 and the comb teeth 61 of the lower fin row 6 are opposite in direction.

[0072] 3) The upper and lower fin rows 6 are conveyed to the corresponding conveyor rollers at the set positions. At this time, the notches 62 of the upper and lower fin rows 6 are opposite to the roller gaps of the corresponding conveyor rollers, which facilitates the subsequent cooperation between the fin rows 6 and the flipping upright plate 312.

[0073] 4) Activate the vertical flipping device 3 to simultaneously flip the upper and lower fin rows 6 from a horizontal position to a standing position;

[0074] 5) Activate the upper pusher component 42 to push the upper fin array 6 from the central position onto the receiving plate seat 444 of the rotating receiving component 44;

[0075] 6) Move the receiving plate seat 444 upward by lifting adjustment seat 443 so that it is longitudinally offset from each component of the assembly equipment and rotate the receiving plate seat 444 to 180° in the plane. At this time, the upper fin row 6 and the lower fin row 6 on the receiving plate seat 444 face the same direction.

[0076] 7) Move the receiving plate seat 444 downward through the lifting adjustment seat 443 to the same height position as the lower transition plate seat 7, start the lower pushing component 43, and push the lower fin array 6 from the centralized position to the receiving plate seat 444 of the rotating receiving component 44. At this time, the upper and lower fin arrays 6 are uniformly connected to the receiving plate seat 444.

[0077] 8) Move the pressing and feeding device 4 to uniformly transport the fin row 6 on the receiving upright plate seat 444 to the pressing and processing line 5.

[0078] Through the above assembly process, after the rotating feeding component 44 is placed on the upper fin row 6, it slightly lifts the receiving stand 444 to offset it from the other components of the assembly equipment. Then, it rotates the receiving stand 444 in the plane to align it with the orientation of the lower fin row 6. This allows the lower fin row 6 to be pushed onto the receiving stand 444 as well, improving the receiving efficiency and facilitating subsequent unified pressing. This process ensures the efficiency of fin row 6 placement, conveying, and pressing, while reducing the need for parallel conveyor lines. The equipment is simple to operate and has a reliable structure.

[0079] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.

An assembly process for transversely inserted fins, based on the assembly equipment as described in any one of claims 1 to 9, specifically comprising the following steps: 1) The fins are punched and output in the form of several pairs of fins in an initial state; 2) The fin pairs in step 1 are synchronously separated to form an upper fin column and a lower fin column, wherein the comb teeth of the upper fin column are opposite to the comb teeth of the lower fin column. 3) The upper and lower fin rows are conveyed to the corresponding conveyor rollers at the set positions. At this time, the notches of the upper and lower fin rows are opposite to the roller gaps of the corresponding conveyor rollers. 4) Simultaneously flip the upper and lower fin rows from a horizontal position to a standing position; 5) Push the upper fin array from the central assembly onto the receiving plate seat of the rotating receiving component; 6) Move the receiving plate seat upwards so that it is longitudinally offset from the components of the assembly equipment and rotate the receiving plate seat to 180° in the plane. At this time, the upper fin row and the lower fin row on the receiving plate seat face the same direction. 7) Move the receiving plate seat downwards and push the lower fin array from the central position onto the receiving plate seat of the rotating receiving component; 8) Move the pressing and feeding device to uniformly transport the fin array on the receiving upright plate to the pressing and processing line.
