Description

Technical Field

[0001] This disclosure relates to assembly technology, and more specifically, to an assembly device and method for a heat exchange and humidification structure. Background Technology

[0002] Heat and humidity exchange structures are widely used in fresh air systems and air conditioning equipment. They typically consist of heat exchange plates and heat exchange films stacked alternately in a preset order, forming isolated or staggered airflow channels inside to achieve heat and moisture exchange between different airflows. Therefore, the production process of heat and humidity exchange structures requires stacking heat exchange plates and heat exchange films layer by layer according to a set number of layers and order.

[0003] In the existing production method, the assembly method of pre-cut diaphragms requires cutting the roll heat exchange diaphragms into a large number of sheet heat exchange diaphragms before assembly. The cut diaphragms are then collected, transported and fed, and then automated equipment is used to pick up and place the pre-cut heat exchange diaphragms and heat exchange sheets and stack them.

[0004] However, while heat exchange fins possess a certain rigidity and can be temporarily stacked using trays, heat exchange films are typically thin, flexible sheets. After being cut from rolls, these films are prone to misalignment, adhesion, and localized warping during handling, transport, and stacking. Positional deviations in the heat exchange films during stacking make subsequent handling mechanisms difficult to compensate for, and the accumulation of stacking errors occurs with the number of layers. Therefore, in the current automated assembly process of heat exchange and humidification structures, the problem of poor stacking accuracy caused by the material of the heat exchange films still exists.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure. Summary of the Invention

[0006] The purpose of this disclosure is to provide an assembly device and assembly method for a heat exchange and humidification structure, which solves the problem of poor stacking accuracy caused by the material of the heat exchange diaphragm in the automated assembly of existing heat exchange and humidification structures.

[0007] Other features and advantages of this disclosure will become apparent from the following detailed description, or may be learned in part by practice of this disclosure.

[0008] According to one aspect of this disclosure, an assembly device for a heat exchange and humidity exchange structure is provided for assembling a heat exchange and humidity exchange structure formed by alternating layers of heat exchange plates and heat exchange films, including an assembly mechanism and a heat exchange plate assembly module and a heat exchange film assembly module for providing heat exchange plates and heat exchange films to the assembly mechanism, respectively. The heat exchange film assembly module includes a die-cutting assembly and a vacuum conveyor belt connected to the die-cutting assembly. The die-cutting assembly is used to roll-die-cut the heat exchange film material to continuously form a heat exchange film adapted to the heat exchange plate. The vacuum conveyor belt has a conveying surface for receiving and adsorbing the heat exchange film. The vacuum conveyor belt is provided with a straightening component at its feed end. The straightening component includes at least one straightening roller disposed opposite to the conveying surface. The straightening roller has a plurality of air blowing holes facing the conveying surface. At least a portion of the air blowing holes have an airflow component extending along the conveying surface from the center of the heat exchange diaphragm toward its edge, so as to make the heat exchange diaphragm unfold along the conveying surface.

[0009] Optionally, the straightening assembly includes three straightening rollers spaced apart along the conveying direction of the vacuum conveyor belt, the three straightening rollers being a central roller located in the middle and two side rollers located on both sides of the central roller along the conveying direction.

[0010] Optionally, fixed frames are provided on both sides of the vacuum conveyor belt, and fixed seats are provided on the fixed frames. The two ends of each straightening roller are rotatably connected to the mounting seats, and the mounting seats are connected to the fixed seats. The mounting seat corresponding to the middle roller is fixedly set relative to the fixed seats, and the mounting seats corresponding to the two side rollers are slidably set on the fixed seats along the conveying direction of the vacuum conveyor belt.

[0011] Optionally, the plurality of air holes are spaced apart along the axial direction of the straightening roller, and include a central hole located in the middle of the straightening roller and a plurality of side holes located on both sides of the central hole respectively; The air outlet direction of the central hole is toward the conveying surface, and the air outlet direction of the side hole is inclined away from the center of the straightening roller relative to the direction toward the conveying surface, so that the airflow acting on the heat exchange diaphragm tends to spread from the center of the heat exchange diaphragm to both sides.

[0012] Optionally, along the direction extending from the middle of the straightening roller to both ends, the angle of inclination of the air outlet direction of the plurality of side holes relative to the direction perpendicular to the conveying surface gradually increases.

[0013] Optionally, the straightening roller has an air blowing channel formed inside, and the plurality of air blowing holes are respectively connected to the air blowing channel. The straightening assembly further includes: An air tube is provided in the air blowing channel. Two air tubes are symmetrically arranged, and the ends of the two air tubes that are close to each other extend to the area corresponding to the central hole. A sealing element is slidably sleeved on the air tube, and two sealing elements are slidably arranged. The two sealing elements are respectively located on both sides of the area corresponding to the central hole. When the sealing element moves, the side hole can switch between a first state and a second state. In the first state, the two sealing members cut off the connection between the side hole and the air blowing channel, while keeping the middle hole connected to the air blowing channel. In the second state, both the middle hole and the side hole are connected to the air blowing channel.

[0014] Optionally, during the process of the heat exchange diaphragm entering the blowing area corresponding to the straightening component, the sealing element is in a first state, and after the heat exchange diaphragm enters the blowing area corresponding to the multiple straightening rollers, the two sealing elements are switched to a second state.

[0015] Optionally, the assembly mechanism includes an assembly base, which serves as an assembly station for placing the heat exchange and humidity exchange structure to be assembled. The heat exchanger assembly module includes a first pick-and-place section and a heat exchanger temporary storage section. The first pick-and-place section is used to pick up heat exchangers from the heat exchanger temporary storage section and transfer them to the assembly base.

[0016] Optionally, the heat exchange diaphragm assembly module further includes a second pick-and-place section and a vision positioning component. The second pick-and-place section is used to pick up the heat exchange diaphragm from the vacuum conveyor belt and transfer it to the assembly base. The vision positioning component is used to obtain the position information of the heat exchange diaphragm after being corrected by the correction component. The second pick-and-place section adjusts the picking position of the heat exchange diaphragm according to the position information.

[0017] According to another aspect of the present invention, an assembly method is also provided, comprising the following steps: (The assembly equipment employing the heat exchange and humidity exchange structure described above is also provided.) Multiple heat exchange plates are provided in a stacked manner, and the heat exchange plates are picked up one by one through the first pick-and-place section; The roll-shaped heat exchange film is continuously unwound, and during the unwinding process, the heat exchange film is rolled and die-cut to form heat exchange films that are compatible with the heat exchange plates in sequence. The heat exchange film, which has been die-cut, is received by a vacuum conveyor belt, and the conveyor surface is used to adsorb and transport the heat exchange film. During the transport of the heat exchange film along the conveyor surface, air is blown onto the heat exchange film by a correction component, and the airflow acting on the heat exchange film has an airflow component that extends along the conveyor surface from the middle of the heat exchange film toward its edge, so that the heat exchange film unfolds along the conveyor surface and is held in an unfolded state by the adsorption of the vacuum conveyor belt. The position information of the corrected heat exchange diaphragm is obtained, and the picking position of the second picking and placing part on the heat exchange diaphragm is adjusted according to the position information. The second picking and placing part picks up the heat exchange diaphragm and transfers it to the assembly station. The heat exchange plates and heat exchange films are transferred alternately to the assembly station according to a preset assembly sequence until the heat exchange plates and heat exchange films are stacked to a preset number of layers to form the heat exchange and humidity exchange structure.

[0018] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides an assembly device and method for a heat exchange and humidification structure, which integrates a die-cutting component with the assembly equipment for the heat exchange and humidification structure into a continuous operation system. This allows the roll-shaped heat exchange membrane material to be directly die-cut during the assembly process, and the resulting heat exchange membrane sheet is directly transported to the subsequent pick-and-place area. This reduces the intermediate processes of centralized collection, transfer, and reloading of a large number of heat exchange membrane sheets in the pre-cutting method, thereby reducing the possibility of adhesion and warping of the heat exchange membrane sheets. In addition, by setting up a vacuum conveyor belt and a straightening component, the heat exchange membrane sheet is subjected to continuous negative pressure adsorption during the transport process, providing a stable transport state for the heat exchange membrane sheet. The straightening component can generate a straightening effect along the membrane surface to straighten the heat exchange membrane sheet during the transport process, thereby improving the local wrinkles and edge warping of the heat exchange membrane sheet, and thus reducing the stacking error caused by the heat exchange membrane, improving the interlayer alignment accuracy, assembly stability, and finished product consistency of the heat exchange and humidification structure.

Detailed Implementation

[0030] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0031] In the description of this invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component positioned centrally in the connection.

[0032] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] In air handling devices such as fresh air systems and air conditioning, a structure formed by alternating layers of heat exchange plates and heat exchange films is usually used to achieve heat and moisture exchange between different airflows. Since the heat exchange films are usually flexible membrane materials with a small thickness, they are prone to warping, adhesion or positional displacement during cutting, conveying and handling, which affects the stacking accuracy between the heat exchange films and heat exchange plates.

[0034] Based on this, such as Figure 1-7 As shown, this embodiment of the invention provides an assembly device and method for a heat exchange and humidification structure, which is applicable to the automated assembly of heat exchange and humidification structures formed by multi-layer heat exchange plates and multi-layer heat exchange films. Through structural improvements, this embodiment of the invention can at least reduce the stacking accuracy problem caused by the material of the heat exchange films themselves.

[0035] Example 1: like Figure 1 , Figure 4 and Figure 5 As shown, this embodiment of the invention provides an assembly device for a heat exchange and humidification structure, including an assembly mechanism 100 and a heat exchanger assembly module 200 and a heat exchanger film assembly module, respectively used to provide heat exchanger plates and heat exchanger films to the assembly mechanism 100. The heat exchanger film assembly module includes a die-cutting assembly 310 and a vacuum conveyor belt 320 connected to the die-cutting assembly 310. The die-cutting assembly 310 is used to perform rolling die-cutting on the rolled heat exchanger film to continuously form a heat exchanger film adapted to the heat exchanger plates. The vacuum conveyor belt 320... The vacuum conveyor belt 320 has a conveying surface 321 for receiving and adsorbing heat exchange films; the feed end of the vacuum conveyor belt 320 is provided with a straightening component 400, the straightening component 400 includes at least one straightening roller 410 disposed opposite to the conveying surface 321, the straightening roller 410 has a plurality of air blowing holes 430 facing the conveying surface 321, and at least some of the air blowing holes 430 have an airflow component extending along the conveying surface 321 from the middle of the heat exchange film toward its edge, so as to make the heat exchange film unfold along the conveying surface 321.

[0036] Specifically, the assembly mechanism 100 is used to form an assembly station for stacking heat exchange plates and heat exchange films. The heat exchange plate assembly module 200 and the heat exchange film assembly module are respectively used to provide heat exchange plates and heat exchange films to the assembly mechanism 100 according to a preset assembly sequence, so that multiple layers of heat exchange plates and heat exchange films are stacked alternately at the assembly station.

[0037] The heat exchanger assembly module 200 can be used to pre-store multiple heat exchangers and provide them to the assembly mechanism 100 one by one according to the assembly rhythm. Since the heat exchangers themselves have a certain structural rigidity, multiple heat exchangers can be temporarily stored in a stacked manner and then transferred to the assembly mechanism 100 one by one by means of suction cups, robotic arms, etc.

[0038] The heat exchanger assembly module is used to process roll-shaped heat exchanger materials online into heat exchanger sheets that can be directly assembled. It includes a die-cutting assembly 310 and a vacuum conveyor belt 320 located downstream of the die-cutting assembly 310. For example, the roll-shaped heat exchanger material enters the die-cutting assembly 310 along a preset conveying path under traction. The die-cutting assembly 310 periodically cuts the heat exchanger sheet during its continuous movement, thereby sequentially forming heat exchanger sheets that match the outer contour and size of the heat exchanger sheets to be assembled. The die-cutting assembly 310 can employ a rolling die-cutting method, allowing the heat exchanger sheets to be continuously formed during the assembly process of the heat exchange and humidification structure, eliminating the need to pre-cut, collect, and reload a large number of heat exchanger sheets.

[0039] Meanwhile, the vacuum conveyor belt 320 is located downstream of the die-cutting assembly 310 and has a conveying surface 321 for receiving the heat exchange film. After the heat exchange film has been die-cut, it is directly fed into the vacuum conveyor belt 320 after being output from the die-cutting assembly 310, where it is received and conveyed further. A negative pressure chamber can be formed inside the vacuum conveyor belt 320, and the conveying surface 321 is provided with adsorption holes that communicate with the negative pressure chamber. When a negative pressure is generated in the negative pressure chamber, an adsorption effect can be generated at the conveying surface 321. After the heat exchange film enters the conveying surface 321, it can adhere to the conveying surface 321 under the vacuum adsorption effect and move synchronously with the vacuum conveyor belt 320.

[0040] It is understandable that, since the heat exchange film that has just completed the rolling die-cutting is a flexible sheet structure, after it is separated from the continuous roll, it may experience edge lifting, local wrinkles, or unstable laying posture due to factors such as the curling tendency formed by the original roll and electrostatic adsorption.

[0041] Based on this, a straightening assembly 400 is provided at the feed end of the vacuum conveyor belt 320 to straighten the flatness of the heat exchange film after it has been die-cut and enters the vacuum conveyor belt 320. The straightening assembly 400 includes at least one straightening roller, which is positioned above and opposite the conveying surface 321 of the vacuum conveyor belt 320. A conveying space is formed between the straightening roller and the conveying surface 321 for the heat exchange film to pass through, allowing the heat exchange film to pass under the straightening roller under the drive of the vacuum conveyor belt 320. Simultaneously, the straightening roller is provided with multiple air blowing holes 430 facing the conveying surface 321, which can be connected to an air supply device. When the air supply device is working, gas is discharged through the air blowing holes 430 towards the conveying surface 321 of the vacuum conveyor belt 320 and acts on the heat exchange film passing under the straightening roller.

[0042] Furthermore, at least a portion of the multiple air outlets 430 have an airflow component extending along the conveying surface 321 from the center of the heat exchange diaphragm towards its edge. That is, in addition to a pressure component moving towards the conveying surface 321, the airflow also has a lateral component moving along the surface of the heat exchange diaphragm towards its edge.

[0043] When the heat exchange diaphragm enters the corresponding area of ​​the straightening assembly 400, the airflow discharged from the air outlet 430 acts on the heat exchange diaphragm. On one hand, the component of the airflow towards the conveying surface 321 can blow and press the heat exchange diaphragm towards the vacuum conveyor belt 320, making the heat exchange diaphragm adhere tightly to the conveying surface 321; on the other hand, the component of the airflow extending from the center of the heat exchange diaphragm towards the edge can exert an outward spreading effect on the heat exchange diaphragm along the surface of the heat exchange diaphragm, causing the heat exchange diaphragm to gradually unfold from the center to the periphery. Therefore, the straightening assembly 400 and the vacuum conveyor belt 320 can form a mutually cooperating straightening method. The straightening assembly 400 uses airflow with a preset direction to actively unfold the heat exchange diaphragm, while the vacuum conveyor belt 320 adsorbs and holds the unfolded heat exchange diaphragm. As the heat exchange diaphragm continues to be conveyed downstream, its flat state can gradually stabilize.

[0044] In the specific assembly process, the heat exchanger assembly module 200 first provides a layer of heat exchanger to the assembly mechanism 100; at the same time, after the heat exchanger film enters the vacuum conveyor belt 320, it is corrected by the straightening component 400 and continues to be transported to the film picking position; the heat exchanger film picking and placing mechanism picks up the heat exchanger film and stacks it on the corresponding heat exchanger; this cycle continues until the heat exchanger and heat exchanger film reach the preset number of assembly layers, thereby forming a complete heat exchange and humidification structure.

[0045] In this embodiment, the die-cutting component 310 is integrated with the assembly equipment of the heat exchange and humidification structure into a continuous operation system. This allows the roll heat exchange film to be directly die-cut during the assembly process, and the resulting heat exchange film is directly transported to the subsequent pick-and-place area. This reduces the intermediate process of collecting, transferring, and reloading a large number of heat exchange films in the pre-cutting method, thereby reducing the possibility of adhesion and warping of the heat exchange film. In addition, by setting up a vacuum conveyor belt 320 and a straightening component 400, the heat exchange film can be subjected to continuous negative pressure adsorption during the transport process, providing a stable transport state for the heat exchange film. The straightening component 400 can generate a straightening effect along the film surface to straighten the film during the transport process, thereby improving the local wrinkles and edge warping of the heat exchange film, thus reducing the stacking error caused by the heat exchange film, improving the interlayer alignment accuracy, assembly stability, and finished product consistency of the heat exchange and humidification structure.

[0046] like Figure 4 and Figure 5 As shown, the straightening assembly 400 further includes three straightening rollers spaced apart along the conveying direction of the vacuum conveyor belt 320. The three straightening rollers are a central roller 411 located in the middle and two side rollers 412 located on both sides of the central roller 411 along the conveying direction.

[0047] Specifically, three straightening rollers are all positioned above the conveying surface 321 of the vacuum conveyor belt 320. The axial direction of the three straightening rollers can correspond to the width direction of the vacuum conveyor belt 320, allowing each straightening roller to span the conveying area of ​​the heat exchange film on the conveying surface 321. A preset spacing is maintained between adjacent straightening rollers along the conveying direction of the vacuum conveyor belt 320, so that the three straightening rollers form a continuous straightening area of ​​a certain length above the conveying surface 321. The middle roller 411 is located in the middle of the three straightening rollers, and the two side rollers 412 are located upstream and downstream of the middle roller 411, respectively. Each straightening roller is provided with multiple air blowing holes 430 facing the conveying surface 321 of the vacuum conveyor belt 320. At least some of the air blowing holes 430 discharge airflow with an airflow component extending from the center of the heat exchange film towards its edge.

[0048] The three straightening rollers are spaced apart along the conveying direction, so they can form a straightening area extending along the conveying direction as the heat exchange diaphragm moves with the vacuum conveyor belt 320. This allows the three straightening rollers to act on different areas of the heat exchange diaphragm, so that the heat exchange diaphragm is continuously subjected to unfolding and flattening during the conveying process.

[0049] like Figure 4 and Figure 5As shown, further, fixed frames 420 are respectively provided on both sides of the vacuum conveyor belt 320, and fixed seats are provided on the fixed frames 420. The two ends of each straightening roller are rotatably connected to the mounting seat 421, and the mounting seat 421 is connected to the fixed seat. The mounting seat 421 corresponding to the middle roller 411 is fixedly set relative to the fixed seat, and the mounting seats 421 corresponding to the two side rollers 412 are slidably set on the fixed seat along the conveying direction of the vacuum conveyor belt 320.

[0050] Specifically, the vacuum conveyor belt 320 is provided with fixed frames 420 on both sides along its width direction, and the two fixed frames 420 are arranged opposite to each other. The fixed seat is located on the outside of the fixed frame 420. Each straightening roller extends along the width direction of the vacuum conveyor belt 320, and its two ends are rotatably connected to the mounting seats 421 located on both sides of the vacuum conveyor belt 320, so that the straightening roller can be suspended above the conveying surface 321 of the vacuum conveyor belt 320.

[0051] The mounting base 421 corresponding to the middle roller 411 is fixedly set relative to the fixed base, so that the position of the middle roller 411 in the conveying direction of the vacuum conveyor belt 320 remains relatively fixed; the mounting bases 421 corresponding to the two side rollers 412 are slidably set on the fixed base, so that the two side rollers 412 can move relative to the middle roller 411 along the conveying direction of the vacuum conveyor belt 320, thereby changing the distance between the side rollers 412 and the middle roller 411.

[0052] In one embodiment, a chute extending along the conveying direction of the vacuum conveyor belt 320 can be formed on the fixed seat, and the mounting seat 421 corresponding to the side roller 412 slides in cooperation with the chute; when it is necessary to adjust the position of the side roller 412, the mounting seat 421 can slide along the fixed seat and remain in the corresponding position after moving to the preset position.

[0053] For example, when the size of the heat exchange film to be conveyed along the conveying direction is large, the two side rollers 412 can be moved away from the middle roller 411, thereby increasing the overall correction area formed by the three correction rollers along the conveying direction. This allows the heat exchange film to be subjected to the blowing action of the correction rollers over a larger area along the conveying direction after it enters the correction area.

[0054] In addition, for heat exchange films with irregular outer contours or conveyed in different laying directions on the vacuum conveyor belt 320, the positions of the two side rollers 412 relative to the middle roller 411 can be adjusted so that the blowing area formed by the three straightening rollers along the conveying direction corresponds to the actual occupied area of ​​the heat exchange film.

[0055] Furthermore, each straightening roller has its two ends rotatably connected to its corresponding mounting base 421, allowing the straightening roller to rotate relative to the mounting base 421 around its own axis. Since the air blowing hole 430 is provided on the straightening roller, the orientation of the air blowing hole 430 relative to the conveying surface 321 of the vacuum conveyor belt 320 can be changed accordingly by adjusting the circumferential position of the straightening roller relative to the mounting base 421.

[0056] During actual operation of the equipment, the required correction area can first be determined based on the specifications, outer contour, and laying direction of the heat exchange diaphragm to be assembled on the vacuum conveyor belt 320. Taking the central roller 411 as a reference, the mounting seats 421 corresponding to the two side rollers 412 are moved to form a spacing between the two side rollers 412 and the central roller 411 that matches the size of the heat exchange diaphragm. The rotation angle of each correction roller is adjusted according to the direction in which the heat exchange diaphragm needs to unfold, so that the multiple air holes 430 form an air blowing direction that matches the heat exchange diaphragm.

[0057] like Figure 5 , Figure 6 and Figure 7 As shown, in this embodiment of the invention, a plurality of air holes 430 are spaced apart along the axial direction of the straightening roller, and include a central hole 431 located in the middle of the straightening roller and a plurality of side holes 432 located on both sides of the central hole 431; the air outlet direction of the central hole 431 is toward the conveying surface 321, and the air outlet direction of the side holes 432 is inclined away from the middle of the straightening roller relative to the direction toward the conveying surface 321, so that the airflow acting on the heat exchange diaphragm has a tendency to spread from the middle of the heat exchange diaphragm to both sides.

[0058] Specifically, the straightening roller spans across the conveying surface 321 along the width of the vacuum conveyor belt 320, and multiple air-blowing holes 430 are arranged at intervals along the axial direction of the straightening roller, thereby forming corresponding air-blowing areas on the heat exchange diaphragm along its width. The central hole 431 is located at the middle of the straightening roller along its axial direction, with the air outlet direction of the central hole 431 facing the conveying surface 321 of the vacuum conveyor belt 320. This allows the gas discharged through the central hole 431 to directly act on the central region of the heat exchange diaphragm located below the straightening roller. This blows and presses the central region of the heat exchange diaphragm towards the conveying surface 321 of the vacuum conveyor belt 320, causing the central part of the heat exchange diaphragm to adhere to the conveying surface 321. Combined with the negative pressure adsorption of this region by the vacuum conveyor belt 320, this ensures that the central region of the heat exchange diaphragm remains relatively stable.

[0059] Multiple side holes 432 are distributed on both sides of the central hole 431 along the axial direction of the straightening roller, corresponding to the membrane surface areas on both sides of the central region of the heat exchange diaphragm. The air outlet direction of the side holes 432 is inclined away from the central part of the straightening roller relative to the direction toward the conveying surface 321. For example, the multiple side holes 432 located on the central side of the straightening roller have an air outlet direction toward the conveying surface 321 while also having an airflow component toward the corresponding end of the straightening roller. Thus, the airflow formed by the side holes 432 on both sides of the central hole 431 generally diffuses from the central part of the straightening roller to both sides.

[0060] When the heat exchange diaphragm passes under the straightening roller, the central hole 431 acts on the central region of the heat exchange diaphragm, causing the central region to be subjected to downward blowing pressure; at the same time, the side holes 432 on both sides blow air into the side regions of the heat exchange diaphragm respectively. Therefore, while blowing the side regions of the heat exchange diaphragm towards the conveying surface 321, it can also produce a flattening effect on the heat exchange diaphragm from the center to both sides.

[0061] For example, to facilitate matching with the heat exchange diaphragm, the middle roller 411 may have three rows of air holes 430 spaced circumferentially on the side facing the conveying surface 321, with at least one row of air holes 430 perpendicular to the conveying surface 321; the side roller 412 may have two rows of air holes 430 spaced circumferentially on the side facing the conveying surface 321, with at least one row of air holes 430 perpendicular to the conveying surface 321, and the other row of air holes 430 on the side away from the middle roller 411. Thus, the air holes 430 of the three straightening rollers 410 work together to straighten the heat exchange diaphragm, further improving the flattening effect of the heat exchange diaphragm.

[0062] like Figure 5 , Figure 6 and Figure 7 As shown, further, along the direction extending from the middle of the straightening roller 410 to both ends, the angle of inclination of the air outlet direction of the plurality of side holes 432 relative to the direction perpendicular to the conveying surface 321 gradually increases.

[0063] Specifically, multiple side holes 432 are respectively disposed on both sides of the central hole 431 along the axial direction of the straightening roller, and are arranged sequentially from the position closest to the central hole 431 to the position closest to both ends of the straightening roller. The side holes 432 disposed near the central hole 431 have a small inclination angle relative to the direction perpendicular to the conveying surface 321, so the airflow discharged from them mainly exhibits a blowing and pressing effect towards the conveying surface 321, while having a relatively small outward spreading effect; as the side holes 432 gradually move away from the central hole 431 and closer to the end of the straightening roller along the axial direction of the straightening roller, the inclination angle of each side hole 432 gradually increases, so that the component of the airflow extending outward along the conveying surface 321 in the discharged airflow gradually increases.

[0064] In other words, in the region corresponding to the axial direction of the straightening roller along the heat exchange diaphragm, the lateral expansion effect of the straightening airflow gradually increases from the center of the heat exchange diaphragm towards its two edges. The region near the center of the heat exchange diaphragm is mainly subjected to a blowing and pressing effect towards the conveying surface 321, while the region closer to the edge of the heat exchange diaphragm is subjected to a more significant outward expansion effect.

[0065] Because rolled membrane materials tend to have a certain degree of curling memory during long-term winding, the heat exchange diaphragm after die-cutting usually exhibits a noticeable tendency to curl up at the edges. By making the side holes 432 near the edge of the heat exchange diaphragm have a larger tilt angle, the outward airflow component acting on the edge area of ​​the diaphragm can be increased. This allows for targeted unfolding of the edge area prone to curling, thus maintaining the heat exchange diaphragm's tendency to adhere to the conveying surface 321 while simultaneously allowing it to stretch outwards. This reduces the possibility of the airflow directly blowing the heat exchange diaphragm away from the conveying surface 321 or causing the diaphragm to drift as a whole.

[0066] For example, for heat exchange films of different widths, different outer contours, or conveyed using different laying directions, the overall orientation of the air blowing holes 430 can be adaptively adjusted by combining the rotation adjustment of the straightening roller relative to the mounting base 421, so that the air blowing direction that gradually increases from the middle to both ends can match the actual unfolding direction of the heat exchange film, thereby improving the applicability of the straightening assembly 400 to heat exchange films of different specifications.

[0067] like Figure 5 , Figure 6 and Figure 7 As shown, in this embodiment of the invention, an air blowing channel 440 is formed inside the straightening roller, and multiple air blowing holes 430 are respectively connected to the air blowing channel 440. The straightening assembly 400 also includes an air pipe 450 and a sealing member 460. The air pipe 450 is disposed in the air blowing channel 440, and two air pipes 450 are symmetrically arranged. The ends of the two air pipes 450 that are close to each other extend to the area corresponding to the central hole 431. The sealing member 460 is slidably sleeved on the air pipe 450, and two sealing members 460 are slidably arranged. The two sealing members 460 are respectively located on both sides of the area corresponding to the central hole 431. When the sealing member 460 moves, the side hole 432 can be switched between a first state and a second state. In the first state, the two sealing members 460 cut off the communication between the side hole 432 and the air blowing channel 440, and keep the central hole 431 connected to the air blowing channel 440. In the second state, both the central hole 431 and the side hole 432 are connected to the air blowing channel 440.

[0068] Specifically, an air blowing channel 440 is formed inside the straightening roller, and multiple air blowing holes 430 provided on the straightening roller are respectively connected to the air blowing channel 440. Externally supplied gas can enter the air blowing channel 440 and be discharged towards the conveying surface 321 of the vacuum conveyor belt 320 through the corresponding air blowing holes 430.

[0069] Two air pipes 450 are provided, and the two air pipes 450 are symmetrically arranged with respect to the middle area of ​​the straightening roller. The ends of the two air pipes 450 that are close to each other extend to the area corresponding to the middle hole 431. The air pipes 450 can serve as the air supply structure inside the air blowing channel 440. A sealing member 460 is slidably sleeved on each of the two air pipes 450. The two sealing members 460 are located on both sides of the area corresponding to the middle hole 431. The sealing member 460 can move relative to the air pipe 450 along the extension direction of the corresponding air pipe 450, and change the communication state between the air blowing channel 440 and the corresponding side hole 432 during the movement.

[0070] In the first state, the two sealing elements 460 are positioned between the central hole 431 and the two side holes 432, respectively, cutting off the airflow path between the side holes 432 and the blowing channel 440, while the central hole 431 remains connected to the blowing channel 440. At this time, the gas entering the blowing channel 440 is mainly discharged through the central hole 431 towards the conveying surface 321 of the vacuum conveyor belt 320, causing the correction assembly 400 to form a concentrated blowing state with the central region of the heat exchange diaphragm as the main operating area. In the second state, the two sealing elements 460 move to the side of the side holes 432 away from the central hole 431, so that both the central hole 431 and the side holes 432 are connected to the blowing channel 440, thereby simultaneously blowing air into both the central and side regions of the heat exchange diaphragm.

[0071] The sealing component 460 can be driven by an electric push rod, a motor, or other means, so that the two sealing components 460 reciprocate between preset positions and correspond to the conveying position of the heat exchange diaphragm on the vacuum conveyor belt 320, thereby realizing automatic switching between the first state and the second state.

[0072] Furthermore, during the process of the heat exchange diaphragm entering the blowing area corresponding to the straightening component 400, the sealing component 460 is in the first state. After the heat exchange diaphragm enters the blowing area corresponding to the multiple straightening rollers, the two sealing components 460 switch to the second state.

[0073] For example, after the heat exchange diaphragm is rolled and die-cut by the die-cutting assembly 310, it is received by the vacuum conveyor belt 320 and moves along the conveying direction with the vacuum conveyor belt 320. During the process of the heat exchange diaphragm entering the blowing area corresponding to the straightening assembly 400, the two sealing members 460 located inside the straightening roller are in a first state. In the first state, the two sealing members 460 respectively cut off the connection between the side hole 432 and the blowing channel 440, while the central hole 431 remains connected to the blowing channel 440, so that the gas supplied into the blowing channel 440 is mainly discharged through the central hole 431. At this time, the airflow discharged from the central hole 431 mainly acts on the central region of the heat exchange diaphragm, and blows the central region toward the conveying surface 321 of the vacuum conveyor belt 320. The vacuum conveyor belt 320 adsorbs the central part of the heat exchange diaphragm through negative pressure adsorption, so that the heat exchange diaphragm first establishes a relatively stable flat laying reference in the central region.

[0074] Because the heat exchange diaphragms have inconsistent shapes, they may be transported diagonally in the same direction as the conveying direction. Before the heat exchange diaphragm fully enters the correction zone, the side holes 432 are kept closed to reduce the premature action of the inclined side airflow on the unstable edge region of the heat exchange diaphragm. Therefore, in the initial stage of the heat exchange diaphragm entering the correction assembly 400, it is mainly subjected to a blowing action towards the conveying surface 321.

[0075] When the heat exchange diaphragm enters the air blowing area corresponding to the multiple straightening rollers, the two sealing components 460 switch from the first state to the second state. In the second state, the central hole 431 and the multiple side holes 432 are connected to the air blowing channel 440. At this time, the central hole 431 continues to blow air toward the central area of ​​the heat exchange diaphragm to maintain the adhesion of the central area of ​​the heat exchange diaphragm to the conveying surface 321; at the same time, the multiple side holes 432 located on both sides of the central hole 431 begin to blow air toward the side areas of the heat exchange diaphragm, so that the side areas of the heat exchange diaphragm gradually move closer to the vacuum conveyor belt 320, and at the same time, the heat exchange diaphragm gradually expands to both sides based on the relatively stable central area.

[0076] Therefore, the heat exchange diaphragm undergoes a phased attitude correction process as it passes through the correction assembly 400. In the first phase, the concentrated airflow formed by the central hole 431 causes the central region of the heat exchange diaphragm to first approach and adhere to the vacuum conveying surface 321. In the second phase, after the heat exchange diaphragm enters the blowing area corresponding to the multiple correction rollers, the side holes 432 are opened, allowing the airflow range to expand from the center of the heat exchange diaphragm to both sides, thereby further eliminating curling, warping, or wrinkles on both sides of the heat exchange diaphragm.

[0077] like Figure 1 , Figure 2 and Figure 3As shown, in this embodiment of the invention, the assembly mechanism 100 includes an assembly base 110, which serves as an assembly station for placing the heat exchange and humidification structure to be assembled; the heat exchanger assembly module 200 includes a first pick-and-place section 210 and a heat exchanger temporary storage section 220, which is used to pick up heat exchangers from the heat exchanger temporary storage section 220 and transfer them to the assembly base 110.

[0078] Specifically, the upper surface of the assembly base 110 forms an assembly bearing area for supporting the heat exchanger plates, heat exchange film, and the heat exchange and humidification structure formed by stacking them layer by layer. During equipment operation, after the heat exchanger plate assembly module 200 transfers the heat exchanger plates to the assembly base 110, the heat exchange film assembly module 300 transfers the heat exchange film, which has been die-cut, conveyed, and corrected, to the corresponding heat exchanger plate, so that the heat exchange film and the heat exchanger plate are stacked in a predetermined position.

[0079] The heat exchanger storage section 220 is used to centrally store multiple heat exchangers to be assembled during the operation of the assembly equipment. Since heat exchangers have higher structural rigidity than heat exchange films and are less prone to significant curling or folding, multiple heat exchangers can be stacked vertically layer by layer in the heat exchanger storage section 220. The first pick-and-place section 210 can adopt a vacuum adsorption structure to pick up heat exchangers one by one from the heat exchanger storage section 220 according to a preset assembly rhythm and transfer the picked-up heat exchangers to the assembly base 110.

[0080] Furthermore, the heat exchange diaphragm assembly module also includes a second pick-and-place unit 330 and a vision positioning component. The second pick-and-place unit 330 is used to pick up the heat exchange diaphragm from the vacuum conveyor belt 320 and transfer it to the assembly base 110. The vision positioning component is used to obtain the position information of the heat exchange diaphragm after it has been corrected by the correction component 400. The second pick-and-place unit 330 adjusts the pick-up position of the heat exchange diaphragm according to the position information.

[0081] Specifically, the second pick-and-place unit 330 is located between the vacuum conveyor belt 320 and the assembly base 110. It can reciprocate between the film-picking position corresponding to the vacuum conveyor belt 320 and the film-dispensing position corresponding to the assembly base 110 to complete the absorption, transfer, and release of the heat exchange film. The second pick-and-place unit 330 can adopt a vacuum adsorption type pick-and-place structure. After the heat exchange film is rolled and die-cut by the die-cutting assembly 310, it is received by the vacuum conveyor belt 320 and conveyed backward. When it passes through the aforementioned straightening assembly 400, it is straightened by blowing air. After the straightening is completed, the heat exchange film continues to be conveyed along the vacuum conveyor belt 320 to the film-picking area corresponding to the second pick-and-place unit 330.

[0082] The visual positioning component is set in the film taking area on the vacuum conveyor belt 320, and is used to obtain the actual position information of the heat exchange film on the vacuum conveyor belt 320 before the second taking and placing part 330 picks up the heat exchange film.

[0083] For example, the visual positioning component can be positioned above the vacuum conveyor belt 320, so that the detection area of ​​the visual positioning component covers the film-taking area corresponding to the second pick-and-place section 330. When the calibrated heat exchange film enters the detection area, the visual positioning component acquires the image information corresponding to the heat exchange film, and determines the actual position of the heat exchange film on the vacuum conveyor belt 320 based on the edge, corner, or other contour features that can determine the position of the heat exchange film. When the visual positioning component detects a positional deviation between the actual position of the heat exchange film and the reference pick-up position, it adjusts the pick-up position of the second pick-and-place section 330 according to the detected position information, so that the second pick-and-place section 330 moves to a position corresponding to the current actual position of the heat exchange film before adsorption.

[0084] Example 2: This invention also provides an assembly method, using the heat exchange and humidity exchange structure described above, comprising the following steps: Multiple heat exchange plates are provided in a stacked manner, and the heat exchange plates are picked up one by one through the first pick-and-place section 210; The roll-shaped heat exchange film is continuously unwound, and during the unwinding process, the heat exchange film is rolled and die-cut to form heat exchange films that are compatible with the heat exchange plates in sequence. The heat exchange film that has been die-cut is received by the vacuum conveyor belt 320, and the heat exchange film is adsorbed and transported by the conveyor surface 321. During the transport of the heat exchange film along the conveyor surface 321, the corrective component 400 blows air onto the heat exchange film, and at least part of the airflow acting on the heat exchange film has an airflow component that extends along the conveyor surface 321 from the middle of the heat exchange film toward its edge, so that the heat exchange film unfolds along the conveyor surface 321 and is adsorbed and kept in the unfolded state by the vacuum conveyor belt 320. The position information of the corrected heat exchange diaphragm is obtained, and the picking position of the heat exchange diaphragm by the second picking and placing part 330 is adjusted according to the position information. The heat exchange diaphragm is picked up by the second picking and placing part 330 and transferred to the assembly station. The heat exchange plates and heat exchange films are transferred alternately to the assembly station according to the preset assembly sequence until the heat exchange plates and heat exchange films are stacked to the preset number of layers to form a heat exchange and humidity exchange structure.
