Description

Technical Field

[0001] This invention relates to an assembly and positioning device for a polygonal core, and also to an assembly and positioning method for a polygonal core, belonging to the field of fresh air tooling technology. Background Technology

[0002] Hexagonal heat exchange cores are widely used in fresh air systems. For example, Chinese Utility Model Patent No. ZL201120289817.7 discloses a heat recovery core for a total heat exchanger. This heat recovery core has a frame around its edge and a hexagonal structure, comprising multiple overlapping hexagonal core sheets. Similarly, Chinese Invention Application No. 202111514607.8 discloses a hexagonal airflow plate for an intelligent fresh air system, its processing method, and a heat exchange core. However, existing technologies lack efficient and convenient solutions for assembling such polygonal cores using existing tooling and processes.

[0003] exist Figure 6 The hexagonal core shown includes a lower end cap, an upper end cap, and a core sandwiched between the lower and upper end caps. The core is a single unit, and the entire core, end caps, corner protectors, and side panels are all made of plastic. During assembly, adhesive is applied to the end caps, corner protectors, and side panels, which are then bonded to the core, forming the complete assembled core. Furthermore, the corner protectors, side panels, and end caps need to be bonded together to form a frame structure, providing overall support for the core.

[0004] Because the adhesive itself needs to be left to cure completely before it can bond firmly, this curing process takes about 30 minutes to reach optimal bond strength. To improve assembly efficiency, it's impossible to wait until it's fully cured before assembling. Therefore, positioning and assembly must be performed while the adhesive is still wet, which makes precise positioning difficult.

[0005] Furthermore, since positioning the hexagonal core requires avoiding the corners and the two opposing side plates, positioning can only be achieved using the beveled edge. However, because the beveled edge has a certain angle, the application of supporting force will create two component forces in different directions. When the colloid is not dry, relative displacement is particularly likely to occur, making the design of beveled edge positioning very difficult. Moreover, the hexagonal core has a high degree of freedom in positioning and requires high dimensional accuracy.

[0006] Overall, the current hexagonal cores lack dedicated assembly and positioning devices, making automated production impossible. Ordinary positioning methods cannot meet the requirements, and the positioned products cannot guarantee their shape. This presents difficulties in operation, is time-consuming and labor-intensive, and does not improve production efficiency. Summary of the Invention

[0007] The primary technical problem to be solved by the present invention is to provide an assembly and positioning device for a polygonal core.

[0008] Another technical problem to be solved by the present invention is to provide a method for assembling and positioning a polygonal core.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] According to a first aspect of the present invention, an assembly and positioning device for a polygonal core is provided, comprising a bracket, a horizontal push plate mechanism, a vertical push plate mechanism, and an inclined side positioning mechanism; wherein...

[0011] The bracket includes a horizontal section and a vertical section perpendicular to the horizontal section, and the horizontal push plate mechanism is installed on the horizontal section to move in the horizontal direction;

[0012] The horizontal push plate mechanism includes at least two push plates, which are symmetrically arranged and have surfaces conforming to the contour of the polygonal core.

[0013] The vertical push plate mechanism includes a pressure plate that can move up and down in the vertical direction. The pressure plate includes a pressure plate moving part and a pressure plate. The shape of the pressure plate is consistent with the shape of the upper surface of the polygonal core. The pressure plate moving part drives the pressure plate to move up and down in the vertical direction.

[0014] The inclined side positioning mechanism includes two top edge baffles, which are fixed on the side of the horizontal part away from the horizontal push plate mechanism.

[0015] Preferably, the assembly positioning device further includes a distal corner plate disposed on the side of the horizontal portion away from the horizontal push plate mechanism, and has a surface conforming to the shape of the corner of the polygonal core.

[0016] Preferably, the assembly positioning device further includes a proximal corner plate disposed on the side of the horizontal portion near the horizontal push plate mechanism, and has a surface conforming to the shape of the corner of the polygonal core.

[0017] Preferably, the assembly positioning device further includes a straight edge positioning mechanism, which is positioned at a location corresponding to the straight edge of the polygonal core.

[0018] Preferably, the distal corner plate is arranged parallel to the two top edge baffles.

[0019] Preferably, the proximal apex plate is disposed on the push plate.

[0020] Preferably, the push plate includes two symmetrically arranged wing plates, each wing plate having a wing plate plane, the wing plate plane forming an angle with the moving direction of the horizontal push plate mechanism.

[0021] Preferably, the proximal apex plate is disposed between the two wing plates and is detachably connected to one of the two wing plates.

[0022] According to a second aspect of the present invention, a method for assembling and positioning a polygonal core is provided, comprising the following steps:

[0023] Place the hexagonal core with the glued bottom cover into the bracket, use the horizontal push plate mechanism to push the bottom cover towards the two top edge baffles, and then reset the horizontal push plate mechanism.

[0024] Place the main body on the bottom cover, and then use the horizontal push plate mechanism to push the main body towards the two top edge baffles, so that the main body is pressed against the two top edge baffles; and maintain the state of pressing the main body against the two top edge baffles;

[0025] The top cover with pre-adhesive is placed on top of the main body, and then the top cover, the main body and the bottom cover are pressed together in the vertical direction using a vertical push plate mechanism;

[0026] Attach the pre-adhesive corner protector to the far corner protector of the hexagonal core, then press the far corner plate onto the far corner protector, and attach the adhesive-coated corner protector to the near corner protector of the hexagonal core, pressing the near corner plate onto the near corner protector.

[0027] Finally, the horizontal push plate mechanism, the vertical push plate mechanism, the far-end corner plate, and the near-end corner plate are reset, and the assembled polygonal core is removed.

[0028] Preferably, the assembly and positioning method further includes attaching two side plates with pre-adhesive to the two opposite straight edges of the hexagonal core before attaching the far end corner or the near end corner, and then pressing the straight edge positioning mechanism onto the side plates so that the side plates are reliably adhered to the two opposite straight edges of the top cover, the main core and the end cover.

[0029] Compared with existing technologies, the assembly positioning device and method provided by this invention can achieve positioning in 10 degrees of freedom, enabling both rapid center positioning and positioning of all edges. The operation is convenient, simple, and flexible. The processed hexagonal core has pressing and positioning functions in all 10 degrees of freedom, and can be released and pressed in all directions. This invention is suitable for assembling and positioning polygonal cores of various shapes and sizes; the high accuracy of the oblique edge positioning ensures that the dimensional tolerance of the assembled core product is within 0.5mm, improving the product quality of the core.

[0036] The technical content of the present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0037] <First Embodiment>

[0038] like Figures 1-3 As shown, this embodiment of the invention first provides an assembly and positioning device for assembling and positioning a polygonal core. In one embodiment of the invention, the polygonal core is hexagonal, and the following description is based on this hexagonal core. However, those skilled in the art will understand that the assembly and positioning device provided in this embodiment of the invention can also be used for polygonal cores such as octagons or dodecagons that simultaneously have hypotenuses and straight edges.

[0039] The polygonal core is composed of multiple layers of thin sheets of the same shape, heat-pressed together layer by layer. In one embodiment of the invention, the two opposite straight edges of the polygonal core are parallel to each other, and these two straight edges cannot be subjected to opposing forces for positioning because they are used for heat-sealing adjacent sheets. The other four edges are not parallel to these two straight edges and are called hypotenuses. In another embodiment of the invention, positioning is achieved using the four hypotenuses. Therefore, during assembly and positioning, to ensure positioning accuracy, it is necessary to consider that applying force to the hypotenuses will result in two directional force components (a horizontal component parallel to the straight edge and a vertical component perpendicular to the straight edge), which could cause the polygonal core to shift. This embodiment of the invention utilizes a combination of angular positioning and hypotenuse positioning to overcome the shift caused by hypotenuse positioning alone.

[0040] Here, the polygonal core is not limited to a symmetrical structure; it can also be an asymmetrical structure. In one embodiment of the invention, a symmetrical hexagon is used as an example. The assembly and positioning device provided in this embodiment can be used for both symmetrical and asymmetrical polygonal cores. When assembling an asymmetrical polygonal core, it is only necessary to adjust the shape of the pressure plate 422 accordingly and adjust the relative positions of each component accordingly to adapt to the outer contour of the asymmetrical polygonal core.

[0041] In one embodiment of the present invention, the assembly positioning device provided by the present invention includes a bracket 1, a horizontal push plate mechanism 3, a vertical push plate mechanism 4, a straight edge positioning mechanism 6, and an inclined edge positioning mechanism 7. Since this embodiment of the present invention is for a hexagonal core, the number of straight edge positioning mechanisms 6 is two; the number of inclined edge positioning mechanisms 7 is two. However, if the assembly positioning is for an octagonal core, then the number of straight edge positioning mechanisms 6 is two; the number of inclined edge positioning mechanisms 7 is at least four; if the assembly positioning is for a dodecagonal core, then the number of straight edge positioning mechanisms 6 is two; the number of inclined edge positioning mechanisms 7 is at least eight.

[0042] The bracket 1 has a horizontal section 11 and a vertical section 12 perpendicular to the horizontal section. A horizontal push plate mechanism 3 is mounted on the horizontal section 11. The horizontal push plate mechanism 3 can move smoothly in the horizontal direction under the drive of pneumatic pressure or a motor. The horizontal push plate mechanism 3, as... Figure 3 and 4 As shown, it includes a slide rail 31, a horizontal drive component 32, a slide block 33, and a push plate 34.

[0043] The slide rail 31 is fixedly mounted on the horizontal part 11, and the bottom of the slide block 33 is slidably disposed on the slide rail 31; the rear end of the slide block 33 is connected to the horizontal drive member 32; the front end of the slide block 33 is connected to the push plate 34. Here, the front end refers to the direction facing the assembled core; the rear end is the opposite direction to the front end. In this embodiment, the push plate 34 includes two sets of push arms 341 arranged symmetrically about the center line of the slide rail (that is, the direction of movement of the horizontal push plate mechanism).

[0044] Each push arm 341 includes a wing plate 3411 and a push rod 3412. The wing plate 3411 has a wing plate plane, which forms an angle with the center line of the slide rail (which is also the direction of movement of the horizontal push plate mechanism). This angle is designed based on the angle between adjacent sides of the polygonal core. For example, if the angle between adjacent sides of the polygonal core is θ, then the angle formed between the two wing plate planes is also θ. The push rod 3412 connects the wing plate 3411 and the slide block 33. In one embodiment of the invention, the push rod 3412 consists of two vertically symmetrical rods to provide vertically symmetrical support force to the wing plate 3411, ensuring that the wing plate 3411 is subjected to uniform force during the pushing process. Those skilled in the art will understand that the push rod 3412 can also be a plate, as long as the height of the push rod 3412 is equivalent to the height of the polygonal core, at least 2 / 3 of the height of the polygonal core.

[0045] The two sets of push arms 341 are symmetrical about the center line of the slide rail, so the two wing plates 3411 are also symmetrical about the center line of the slide rail and have surfaces conforming to the contour of the polygonal core. Furthermore, a gap is left between the two wing plates 3411, located on the center line of the slide rail, allowing the joints of adjacent sides of the polygonal core to extend in.

[0046] The vertical push plate mechanism 4 is mounted on the vertical part 12 and includes a vertical drive member 41, a pressure plate 42, and a vertical guide rail 43. The vertical drive member 41 is fixed above the vertical part 12. The vertical guide rail 43 is disposed on the vertical part 12 and extends vertically. Under the force applied by the vertical drive member 41, the pressure plate 42 can move up and down along the guide rail 43 on the vertical part 12.

[0047] The pressure plate 42 includes a pressure plate moving part 421 and a pressure plate 422. The shape of the pressure plate 422 is consistent with the shape of the upper surface of the polygonal core, and is therefore polygonal. In one embodiment of the present invention, since a hexagonal core is being assembled, the shape of the pressure plate 422 is hexagonal. The lower surface of the pressure plate 422 is used to press the upper surface of the polygonal core.

[0048] A vertical drive member 41 connects to a pressure plate moving part 421, which in turn connects to the upper surface of a pressure plate 422. The pressure plate moving part 421 cooperates with a vertical guide rail 43 and moves up and down along the vertical guide rail 43 under the force of the vertical drive member 41. In one embodiment of the invention, the plane containing the pressure plate 422 is perpendicular to the vertical guide rail 43; therefore, as the pressure plate moving part 421 moves up and down along the vertical guide rail 43, the pressure plate 422 can move to different heights and be fixed at those heights.

[0049] On two sides of the pressure plate 422 parallel to the center line of the slide rail, cover pressing mechanisms 5 are respectively provided. The cover pressing mechanism 5 is an openable and self-locking clamping mechanism, such as an elbow clamp mechanism or a hinge clamp mechanism. One end of the cover pressing mechanism 5 is fixed to the side of the pressure plate 422; the other end is fixed to the straight edge positioning mechanism 6. By operating the cover pressing mechanism 5, the straight edge positioning mechanism 6 is opened or closed relative to the pressure plate 422 (i.e., moved away from or closer to the pressure plate). Those skilled in the art will understand that the cover pressing mechanism 5 can also be other structures that enable the straight edge positioning mechanism 6 to open or close, such as a bolted structure, allowing the straight edge positioning mechanism 6 to move away from the polygonal core.

[0050] In one embodiment of the present invention, the straight edge positioning mechanism 6 is a two-piece structure, fixed to the horizontal part 11 or the pressure plate 422 respectively. The straight edge positioning mechanism 6 is a plate whose length and width are conformable to the dimensions of one side of the polygonal core, so that it can fit tightly against one side of the polygonal core, thereby applying pressure to the polygonal core. In one embodiment of the present invention, the straight edge positioning mechanism 6 consists of two symmetrically arranged plates, symmetrically arranged at positions corresponding to the straight edges of the hexagonal core. The upper straight edge positioning mechanism 6 is connected to the upper surface of the pressure plate 422 by a cover pressing mechanism 5; the lower straight edge positioning mechanism 6 is connected to the lower surface of the horizontal part 11 by another cover pressing mechanism 5. Those skilled in the art will understand that the straight edge positioning mechanism 6 can be a single plate extending from the horizontal part 11 to the pressure plate 422. When the height of the polygonal core is small, it is suitable to use a structure where the straight edge positioning mechanism 6 is a single plate. In this embodiment, the straight edge positioning mechanism 6 adopts a two-plate structure, and the height is adjusted by the pressure plate 422 along the vertical track 43, making it suitable for assembling polygonal cores of any height.

[0051] In one embodiment of the invention, the inclined edge positioning mechanism 7 includes two top edge baffles 71. A horizontal push plate mechanism 3 is mounted on one side of the horizontal portion 11 located at the vertical portion 12; the top edge baffles 71 are fixed to the other side of the horizontal portion 11 located at the vertical portion 12. The two top edge baffles 71 are symmetrically arranged about the center line of the slide rail and form a top edge angle. This top edge angle coincides with the angle between the adjacent sides of the polygonal core that abut against the top edge baffles 71, so that the two top edge baffles 71 can make close contact with the adjacent sides, thereby applying pressure to the adjacent sides. Figure 5 As shown, both top edge baffles 71 are fixed to the horizontal part 11.

[0052] The assembly positioning device provided in this embodiment of the invention further includes a distal apex plate 81 and a proximal apex plate 82. The distal apex plate 81 is disposed parallel to the two top edge baffles 71; the proximal apex plate 82 is disposed parallel to the wing plates 3411. The surfaces of the distal apex plate 81 and the proximal apex plate 82 facing the polygonal core are conformed to the angles of the polygonal core to ensure a tight fit with the angles of the polygonal core.

[0053] A proximal apex plate 82 located between winglets 3411 is fixedly connected to one of the winglets 3411, and can therefore switch between open and closed states with the winglet 3411. For example, the apex plate 82 is fixed to one of the winglets 3411 by a connecting plate. The proximal apex plate 82 is closably connected to the winglet 3411 by an elbow clamp, so that the proximal apex plate 82 can be opened (i.e., away from the winglet) or closed (i.e., close to the winglet) relative to the winglet 3411.

[0054] Preferably, the distal corner plate 8 located between the two top edge baffles 71 is divided into upper and lower pieces in one embodiment of the invention. The upper piece (top) of the corner plate 8 is connected to the upper surface of the pressure plate 422 by a cover clamping mechanism 5 (e.g., an elbow clamp); the lower piece (bottom) of the distal corner plate 8 is connected to the lower surface of the horizontal portion 11 by another cover clamping mechanism 5. Therefore, the upper piece of the distal corner plate 8 is controlled by an elbow clamp to switch between a state perpendicular to the horizontal portion 11 and a state not perpendicular to the horizontal portion 11. With this design, different sizes of corner plates 8 can be replaced by opening the cover clamping mechanism 5 to accommodate the assembly of polygonal cores of different sizes.

[0055] As an alternative, the lower piece of the distal corner plate 81 is fixed to the apex of the horizontal part 11; the upper piece of the distal corner plate 81 is connected to the upper surface of the flattening part 422 via the cover pressing mechanism 5.

[0056] As an alternative, the far-end corner plate 8 can also be a one-piece structure, without the need for two pieces. If a fixed-size (as long as the angle of the apex remains unchanged) polygonal core is assembled, the lower piece of the far-end corner plate 8 can be replaced with a structure welded to the horizontal part 11.

[0057] <Second Embodiment>

[0058] A second embodiment of the present invention provides an assembly and positioning method for assembling a polygonal core. This assembly and positioning method includes at least the following steps.

[0059] During the preparation phase, both the slide block 33 and the push plate 34 are positioned at the far end (away from the vertical part 12), the cover pressing mechanism 5 is reset to the upper position (away from the horizontal part 11), and the inclined edge positioning mechanism 7 is reset to the outward-folding position. In this state, there is a large space between the push plate 33 and the vertical part 34, allowing the bottom cover of the hexagonal core to be placed within this space.

[0060] When the pre-adhesive bottom cover of the hexagonal core is inserted, the horizontal drive member 32 pushes the push plate 34 towards the bottom cover of the hexagonal core along the slide rail 31, and then the horizontal drive member 32 resets the push plate 34. This pushes the bottom cover of the hexagonal core towards the two top edge baffles 71. Since the top edge baffles 71 are pre-fixed to the edge of the horizontal portion 11 away from the horizontal drive member 32, and an included angle is pre-formed between the two top edge baffles 71, the two top edge baffles 71 conform to the contour of the hexagonal core.

[0061] Then, the main body of the hexagonal core (with adhesive already applied to the bottom) is placed in, and the horizontal drive component 32 is used to push the reset push plate 34 back towards the top edge baffle 71. This presses the main body against the two top edge baffles 71. At this time, the push plate 34 remains in the position pressing the main body against the two top edge baffles 71, that is, the two top edge baffles 71 and the two wing plates 3411 respectively abut against the four inclined sides of the hexagonal core, thereby ensuring that the hexagonal core is accurately positioned and avoiding the displacement that occurs in conventional inclined side positioning.

[0062] With the four inclined sides in contact, place the top cover (with adhesive already on the bottom) on top of the main body, and then use the vertical drive 41 to drive the pressure plate 42 to slide, pushing the hexagonal core to the horizontal part and pressing them together as one, so that the top cover, main body and bottom cover are bonded together in the vertical direction.

[0063] Two side panels (already glued) are attached to the two opposite straight edges of the hexagonal core. Then, the cover pressing mechanism 5 is operated to press the straight edge positioning mechanism 6 onto the side panels, so that the side panels are reliably bonded to the opposite straight edges of the top cover, main core, and end cover. Because the straight edges need to be bonded to the side panels, only beveled edges can be used for positioning in the aforementioned steps, which increases the difficulty of positioning. This invention solves the problem of easy displacement of beveled edge positioning.

[0064] After applying adhesive, the corner protectors are attached to the far corner of the hexagonal core. Then, the pressing mechanism 5 is operated to press the far corner plate 81 onto the far corner. Next, the adhesive-coated corner protectors are attached to the near corner of the hexagonal core, and the pressing mechanism 5 is operated to press the near corner plate 82 onto the near corner. Simultaneously, the far corner plate 81 and the near corner plate 82 are pressed against the hexagonal core and held in a locked state for a predetermined time, thereby assembling the polygonal core.

[0065] Since the far-end corner plate 81 is pre-positioned and is a triangular steel with a pre-set angle (θ), the angles match when the corner of the hexagonal core is pushed toward the far-end corner plate 81; the two hypotenuses are positioned by the opposite side baffles to achieve precise positioning.

[0066] Therefore, the hexagonal core is subjected to relative forces along the centerline by the distal apex plate 81 and the proximal apex plate 82 located on the centerline; it is also subjected to symmetrical forces about the centroid line of the hexagonal core between the two top edge baffles 71 and the two wing plates 3411. It is subjected to symmetrical forces in multiple directions, so it is reliably positioned.

[0067] Since both the horizontal and vertical drive components are powered by air, there is no need for manual pressing of the hexagonal core for extended periods. The core can remain locked for a long time, even if the adhesive has a long curing time.

[0068] Finally, reset the push plate 34, pressure plate 42, and cover pressing mechanism 5, and remove the assembled polygonal core.

[0069] Compared with existing technologies, the assembly positioning device provided in this invention utilizes a top corner plate and a push plate to achieve precise positioning in the first step, and the oblique positioning ensures accurate positioning throughout the entire operation. According to the inventors' experimental results, using the assembly positioning device and method provided by this invention, the dimensional tolerance of the assembled core product can be guaranteed to be within 0.5mm, thereby improving the product quality of the core.

[0070] Furthermore, the assembly positioning device provided by this invention can be freely adjusted using a cover pressing mechanism and slide rails to meet the assembly needs of polygonal cores of various sizes and shapes. Therefore, its application range is wide and not limited to cores; it can also be suitable for assembling multi-layered polygonal objects that are bonded together. Moreover, the assembly positioning device provided by this invention utilizes independently operating corner plates and a two-piece straight-edge positioning mechanism, which allows for easy assembly and disassembly of the corner plates and side plates on the polygonal core, making it suitable for objects of different shapes and sizes, such as octagons.

[0071] The assembly and positioning device and method for the polygonal core provided by this invention have been described in detail above. Any obvious modifications made by those skilled in the art without departing from the essence of this invention will constitute an infringement of the patent rights of this invention and will incur corresponding legal liability.
