Description

Technical Field

[0001] This invention relates to an assembly apparatus and method for a high-efficiency filter, belonging to the field of machining and assembly technology. Background Technology

[0002] HEPA filters are air filtration devices that effectively filter tiny particles in the air. Their core principle is to achieve high-intensity filtration by filtering impurities in the air through filter paper with tiny filtration gaps. However, as the filter paper is used, the voids in the filter paper structure are constantly filled, causing the filter paper efficiency to decrease. After the filter paper reaches the end of its service life, the filter paper structure needs to be replaced. For some heavily polluted or high-requirement cleanrooms, the filter paper replacement cycle can even be as long as three to four months. In order to ensure the service life of the filter paper and a larger filtration area, this filter paper is usually folded and assembled in the HEPA filter housing. When replacing the filter paper in customer usage scenarios, it is difficult to maintain the stability of the structure of this bent filter paper. Moreover, due to the presence of the folded corners of the filter paper, manual replacement of the adhesive can easily lead to leakage points. This is not only cumbersome to operate but also prone to producing defective products, making it difficult to apply to customers' high-efficiency maintenance work. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an assembly device and method for a high-efficiency filter. This provides a new filter paper assembly method to facilitate efficient replacement of filter cores in customers' high-efficiency filter equipment according to customer needs. It can reduce human error while ensuring assembly efficiency, and has better assembly efficiency and quality.

[0004] To achieve the above objectives, the present invention employs the following technical solution: On one hand, the present invention provides an assembly apparatus for a high-efficiency filter, comprising an assembly line for conveying folded filter paper. The assembly line is sequentially configured from upstream to downstream with an adhesive coating assembly, a mesh placement assembly, a side plate assembly assembly, and a connecting strip assembly assembly. The assembly line is divided into a first section and a second section upstream and downstream of the feeding position of the side plate assembly assembly, respectively. The feeding width of the second section of the assembly line is less than the length of the filter paper. The adhesive coating assembly is used to coat an adhesive layer at the crest of the filter paper. The screen placement assembly is used to place a protective screen on the surface of the filter paper; The side panel assembly is used to provide a side adhesive plate, the side adhesive plate including a substrate and an adhesive groove disposed on the substrate, the adhesive groove being able to match the side dimensions of the folded filter paper and being filled with an adhesive layer, the side panel assembly being used to assemble the adhesive groove of the side adhesive plate corresponding to the two sides of the filter paper respectively. The connecting strip assembly is used to install a fixing strip on two opposing bases; A lifting conveyor line is also provided on the side of the second section of the assembly line upstream. The lifting conveyor line includes a lifting mechanism and a receiving line located at the output end of the lifting mechanism. The receiving line is used to receive the side bonding plate assembled on the side of the filter paper. A second conveyor line for conveying the side bonding plate is also provided on the side of the second section of the assembly line downstream.

[0005] Specifically, the adhesive application assembly includes an adhesive tank, a first actuation module, and an adhesive sheet. The first actuation module is used to drive the adhesive sheet to reciprocate between the adhesive dispensing station in the adhesive tank and the surface of the filter paper.

[0006] Specifically, it includes a horizontal rail that can move above the assembly line, and the mesh plate placement assembly includes a first lifting drive component that can move along the extension direction of the horizontal rail. The output end of the first lifting drive component is provided with a suction cup. The bottom surface of the suction cup is provided with an adsorption groove, and the upper surface of the suction cup is provided with a vacuum tube that can communicate with the adsorption groove.

[0007] Specifically, it also includes a thermosetting assembly, which includes a second lifting drive component that can move along the extension direction of the horizontal rail. The output end of the second lifting drive component is provided with a positioning plate, and an air blowing pipe capable of oblique blowing is mounted on the positioning plate.

[0008] Specifically, the side panel assembly includes a material picking platform, a second action module, and a clamping assembly located at the output end of the second action module. The second action module is used to drive the clamping assembly to reciprocate between the material picking platform and the assembly line. The clamping assembly includes a bidirectional lead screw, two clamping plates disposed on the bidirectional lead screw, and a motor for driving the bidirectional lead screw to rotate.

[0009] Specifically, it also includes an edge adhesive curing component. The substrate has a back groove on the side opposite to the adhesive groove. The edge adhesive curing component includes a mounting platform and a pushing component set on the mounting platform. The output end of the pushing component is connected to a mounting plate. The mounting plate has several hollow tubes. Each hollow tube has a water film protruding from the end face of the hollow tube and sealing it. The hollow tube has a heating rod inside for heating the aqueous solution filled inside the hollow tube. The pushing component is used to connect the protruding water film with the inner surface of the back groove.

[0010] Specifically, the base has mounting grooves on both sides, and the mounting grooves have threaded holes inside. The two ends of the fixing strip can match the size of the mounting grooves, and the fixing strip has positioning holes. The second conveyor line is located downstream of the connecting strip assembly and has a screw fastening mechanism.

[0011] On the other hand, the present invention provides a method for assembling a high-efficiency filter, the method comprising the following steps: Apply adhesive to the folded filter paper at the crest position; Place a protective mesh on the surface of the filter paper and bond the protective mesh and the adhesive layer together; Adhesive side bonding plates are attached to both sides of the filter paper structure. Two opposing side adhesive plates are installed together using fixing strips to form a stable frame structure; The frame structure with filter paper is assembled inside the housing of the high-efficiency filter, and the two sides of the filter paper are sealed.

[0012] Specifically, when bonding the side bonding plate, first fill the bonding groove with a porous sponge that has absorbed thermosetting adhesive, and then install the side bonding plate on the side of the filter paper corresponding to the porous sponge.

[0013] Specifically, when installing the side adhesive plates, the positions of the side adhesive plates on both sides are positioned, and the thermosetting adhesive is cured by heating before the positioning of the side adhesive plates is loosened.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: This invention improves the filter paper assembly process by first shaping the filter paper structure using a protective net before assembly. Then, the edges of the filter paper with wavy corners are sealed with adhesive and cured. The use of mounting strips further stabilizes this frame structure. This allows for adhesive application to the wavy corners of the filter paper before assembly. Finally, this frame structure is assembled with the outer frame of the HEPA filter, enabling rapid assembly. During filter paper replacement, there is no need to seal the edges at the wavy corners, providing efficient customer service and significantly improving assembly and replacement efficiency. This also reduces the risk of missed sealing during manual adhesive application at the wavy corners, contributing to improved product quality during filter paper replacement.

[0016] The present invention will be further described below with reference to the accompanying drawings.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances. Example 1

[0019] This invention provides an assembly device for a high-efficiency filter, offering a novel filter paper assembly method to efficiently replace filter cores in customer-required high-efficiency filter equipment. This method ensures assembly efficiency while reducing human error, resulting in superior assembly efficiency and quality. To achieve the device's structural functions, it includes an assembly line 1 for conveying folded filter paper. The assembly line 1 is configured with, from upstream to downstream, a gluing assembly 2, a screen placement assembly 3, a side plate assembly 5, and a connecting strip assembly 8. The assembly line 1 is divided into a first section and a second section (which can be composed of conveyor belt structures at both ends) upstream and downstream of the side plate assembly assembly 5, with the feeding position as the reference point. The feeding width of the second section of the assembly line 1 is less than the length of the filter paper, allowing blank portions to protrude from both ends after the filter paper is conveyed to the second section of the assembly line 1 for subsequent assembly operations. The adhesive coating assembly 2 is configured to apply an adhesive layer at the crest of the filter paper. The specific structure is not limited here. However, as a preferred embodiment, the adhesive coating assembly 2 may include an adhesive tank 201, a first action module 202, and an adhesive sheet 203, as described in [reference needed]. Figure 1 as well as Figure 2As shown, the first action module 202 is used to drive the adhesive sheet 203 to reciprocate between the glue-taking station of the glue tank 201 and the surface of the filter paper. The glue tank 201 should be filled with glue to be cured. The adhesive sheet 203 is used to adhere glue to its bottom surface through movement and to apply the adhered glue to the folded filter paper layer transported by assembly line 1. Since only the highest point of the filter paper crest can contact the glue film layer at the bottom of the adhesive sheet 203, the glue will only adhere at the crest. Considering that if the adhesive sheet 203 is flat, the glue layer may have uneven thickness and be prone to dripping during movement, as another preferred method, the adhesive sheet 203 can be... A flange is provided on the outer side of the bottom surface to form a limiting frame structure for holding the adhesive. During the movement of the adhesive, it can prevent the adhesive from excessively shifting to one side due to acceleration and dripping from the outside of the adhesive sheet 203. The size of this limiting frame structure should be larger than the size of the filter paper. The resistance provided by the flange can suppress the dripping of the adhesive layer from the edge to a certain extent after the adhesive layer adheres. In some other preferred embodiments, the adhesive layer below the flange can be scraped off by a scraper to avoid taking too much adhesive and causing the adhesive to drip continuously downward. In this embodiment, the thickness of the adhesive film layer formed after scraping off the adhesive layer thickness below the flange is preferably between 2-3 mm to achieve stable adhesive taking action. Other preferred embodiments are not limited here. The screen placement assembly 3 is used to place a protective mesh 11 on the surface of the filter paper. By allowing the adhesive layer at the crest of the filter paper to contact the protective mesh 11 to form an adhesive surface, the protective mesh 11 can form a stable connection with the filter paper through the curing of the adhesive layer. This protects the filter paper and stabilizes its shape after the adhesive layer cures (the adhesive layer can be cured while the filter paper is in a constrained position; other methods are not limited here). In a preferred embodiment, the configuration device includes a horizontal rail 12 that can move above the assembly line 1, and the screen placement assembly 3 includes a first lifting drive 301 that can move along the extension direction of the horizontal rail 12. Figure 8 As shown, the output end of the first lifting drive 301 is provided with a suction cup 302, and the bottom surface of the suction cup 302 is provided with an adsorption groove, and the upper surface of the suction cup 302 is provided with a vacuum tube 303 that can connect to the adsorption groove. The adsorption groove is used to adsorb the protective net 11 with multiple holes. It is necessary to pay attention to the position and negative pressure state when picking up the material so that the adsorption point can generate sufficient adsorption force so that the suction cup 302 can accurately carry the protective net 11 and place it on the adhesive layer on the surface of the filter paper. Side panel assembly 5 is used to provide side adhesive plate 6, such as Figure 10 as well as Figure 11As shown, the side bonding plate 6 includes a substrate 601 and an bonding groove 602 disposed on the substrate 601. The bonding groove 602 is configured to match the side dimensions of the folded filter paper and is filled with an adhesive layer. The side plate assembly assembly 5 is used to assemble the bonding groove 602 of the side bonding plate 6 to the two sides of the filter paper respectively. The specific operation method is not limited here. That is, the side bonding plate 6 is assembled on both sides of the folded corner of the filter paper using the side plate assembly assembly 5, so that the side bonding plate 6 can form a stable adhesive connection with the filter paper and achieve the sealing and curing action of the folded corner surface where the filter paper is located. Due to the thin adhesive film thickness in the bonding groove 602 during assembly, This can easily lead to incomplete bonding. If the adhesive film is too thick, it can cause the adhesive to move downwards before curing, resulting in uneven thickness. Therefore, as a preferred embodiment, a sponge with a certain thickness of adhesive layer can be placed in the bonding groove 602. When the side of the filter paper is squeezed against the sponge, the adhesive can seep out and contact the side of the filter paper. After the adhesive cures, a stable connection and seal are formed. This ensures that the adhesive layer is not prone to leakage when it is of a certain thickness. This assembly method can be achieved by manual labor combined with mechanical handling, so as to reduce the complexity of mechanical assembly and inspection (installation of sponge layer and inspection of adhesive state). The connecting strip assembly 8 is used to install the fixing strip 10 on two opposing bases 601, and the final connection structure can be referred to Figure 9 As shown, the connecting strip assembly 8 can use a robotic arm 801 in conjunction with a material gripper 802 to grasp the fixing strip 10 and install the fixing strip 10 on the two side adhesive plates 6. Finally, the frame assembly of the fixing strip 10 is achieved through a locking structure, thereby forming a replacement core structure with a certain structural stability. This formed structure can be directly assembled into the inside of a high-efficiency filter with a corresponding shape during installation. Through sealing assembly, the other two sides of the filter paper can be clamped and sealed directly by the structure, or sealed by manual glue application, which can also save a lot of disassembly and assembly work. Since the sealing of the corrugated corner side is completed in advance, it also helps to improve the sealing performance after the final replacement. The produced assembly structure is also relatively stable and is conducive to transportation. To automate the transportation operations of the assembly line, a lifting conveyor line 14 is also installed on the side at the upstream position of the second section of assembly line 1, such as... Figure 1 as well as Figure 14As shown, the lifting conveyor line 14 includes a lifting mechanism 1401 and a receiving line 1402 located at the output end of the lifting mechanism 1401. The receiving line 1402 is used to receive the side adhesive plate 6 assembled on the side of the filter paper, so that after the side plate assembly assembly 5 is assembled, the receiving line 1402 can support the side adhesive plate 6 in its uncured state. At the same time, a second conveyor line 13 for conveying the side adhesive plate 6 is also provided on the side at the downstream position of the second section of the assembly line 1, so that the second conveyor line 13 can correspond to the conveying position of the receiving line 1402, so that the product can be accurately conveyed downstream when the side adhesive plate 6 is uncured. It should be noted that when the side plate assembly assembly 5 is assembled, the receiving line 1402 should be in a clearance position by lifting, and the height of the conveying position should be able to match the position of the folded filter paper conveyed in the second section of the assembly line 1.

[0020] This invention provides an assembly apparatus for a high-efficiency filter. To accelerate the curing speed of the adhesive layer on assembly line 1, the apparatus further includes a thermosetting component 4. The adhesive filling the adhesive tank 201 is a thermosetting adhesive, and the thermosetting component 4 includes a second lifting drive member 401 capable of moving along the extension direction of the transverse rail 12. Figure 8 As shown, the output end of the second lifting drive 401 is equipped with a positioning plate 402. The positioning plate 402 is equipped with an air blowing pipe 403 capable of oblique blowing. The air blowing pipe 403 is used to blow hot air onto the surface of the folded filter paper so that the protective net 11 placed on the surface of the filter paper can quickly form an adhesive state with the filter paper structure, thereby quickly achieving stable shaping of the filter paper structure. The second lifting drive 401 is configured to move along the extension direction of the horizontal rail 12, thereby providing a wider blowing range. Since the first lifting drive 301 is also configured on the horizontal rail 12, it can perform high-efficiency operation while saving structure. When the first lifting drive 301 drives the suction cup 302 to pick up the material, the air blowing pipe 403 can be replaced to blow air at the working position. The two alternately operate, which can effectively save structural space.

[0021] This invention provides an assembly device for a high-efficiency filter, specifically offering a side plate assembly assembly 5. Specifically, the side plate assembly assembly 5 includes a material handling platform 501, a second action module 502, and a clamping assembly located at the output end of the second action module. Figure 1 as well as Figure 3As shown, the second action module 502 is configured to drive the clamping assembly to reciprocate between the picking table 501 and the assembly line 1. Preferably, the clamping assembly includes a bidirectional lead screw 503, two clamping plates 504 disposed on the bidirectional lead screw 503, and a motor for driving the bidirectional lead screw 503 to rotate. When picking up the side adhesive plate 6 for installation, the clamping plates 504, which can move relative to each other, are used to clamp the side adhesive plate 6, and the second action module 502 is used to move it to the assembly position. The material on the picking table 501 can be prepared and placed manually. In some other preferred embodiments, automated assembly inspection feeding can also be used. It should be noted that the picking table 501 should be provided with a limit structure to ensure the accuracy of the feeding position.

[0022] This invention provides an assembly device for a high-efficiency filter. Considering that after the side bonding plate 6 is installed and transported, a film of a certain thickness is located on the inner side of the side bonding plate 6, in order to accelerate the curing speed of the inner adhesive layer, the device further includes an edge adhesive curing component 7. Specifically, a back groove 604 is provided on the side of the substrate 601 opposite to the bonding groove 602. This back groove 604 is opposite to the bonding groove 602 to shorten the thickness of the metal parts between the two grooves. The edge adhesive curing component 7 includes a mounting platform 701 and a pushing component 702 disposed on the mounting platform 701. Figure 12 and Figure 13 As shown, the output end of the push assembly 702 is connected to a mounting plate 703. The mounting plate 703 has several hollow tubes 704. Each hollow tube 704 has a water film 705 protruding from its end face and sealing it. The height of the water film 705 should match the height of the back groove 604 so that the water film 705 can move into the back groove 604. Inside the hollow tube 704, a heating rod 706 is provided for heating the solution (such as ethylene glycol, boiling point approximately 197°C) filling the hollow tube 704, so that the heating rod 706 can heat the solution located inside the hollow tube 704. 04 The internally filled solution is heated, and the pushing component 702 is used to connect the raised water film 705 with the inner surface of the back groove 604, so as to realize the heat exchange between the metal surface where the water film 705 and the back groove 604 are located, thereby accelerating the temperature rise of the metal and rapidly increasing the temperature of the inner adhesive layer. By setting two such edge adhesive curing components 7 on both sides of the assembly line 1, the flexible contact of the water film 705 can increase the heating surface while avoiding the squeezing of the filter paper by the side adhesive plate 6 caused by the rigid contact of the structure. This can avoid damaging the folding structure of the filter paper and control the pressure during heating within a reasonable range.

[0023] The present invention provides an assembly device for a high-efficiency filter. To facilitate the positioning and connection of the fixing strip 10, mounting grooves 603 are provided on both sides of the base 601. Threaded holes are provided inside the mounting grooves 603. The two ends of the fixing strip 10 are configured to match the size of the mounting grooves 603, and the fixing strip 10 is provided with positioning holes. By limiting the connection through the positioning holes, the positional deviation of the fixing strip 10 caused by the product during the process of conveying can be avoided. At this time, a screw fastening mechanism 9 is provided at the downstream position of the connecting strip assembly assembly 8 on the second conveyor line 13. The fixing strip 10 and the side adhesive plate 6 are fastened together by the screw fastening mechanism 9, which can ensure the structural stability of the product. Example 2

[0024] This invention provides a method for assembling a high-efficiency filter, used in the rapid replacement of high-efficiency filters. This method facilitates maintenance of customer equipment while ensuring high product yield after replacement. The assembly method includes the following steps: Apply glue to the crest of the folded filter paper. At this time, the shape of the crest can be shaped by pre-applying glue to the folded filter paper. Since this is existing technology, it will not be explained in detail here. The pre-shaped filter paper has a certain stability after being transported, which can prevent the filter paper structure from collapsing during the transport process. In some other embodiments, the structure of the filter paper can be constrained by a limiting structure during the transport process. The design of the limiting structure is not limited here. It is sufficient to ensure the stability of the filter paper shape when the protective net 11 is laid later. After the glue application is completed, a protective net 11 is placed on the surface of the filter paper and the protective net 11 is bonded to the adhesive layer. The adhesive layer can be UV glue or thermosetting glue, etc. Since the protective net 11 covers the bonding point after it is laid, UV curing is easily hindered. At this time, it is preferable to use thermosetting glue. Hot air flows on the surface of the folded filter paper to quickly achieve the curing effect of the glue. After the filter paper and protective net 11 form a stable adhesive structure, the two side adhesive plates 6 are respectively bonded to both sides of the filter paper structure through the adhesive side adhesive plates 6, thereby achieving the sealing action at the wavy edge of the filter paper. The bonding and curing of the adhesive can also be done in the form of thermosetting adhesive. The specific thermosetting method can refer to the flexible contact heating of the water film 705 shown in Embodiment 1. When the width of the water film 705 is limited, the contact position of the water film 705 can be changed by moving the side adhesive plates 6 and the overall structure of the filter paper, thereby ensuring the curing state of each adhesive application position. After the glue cures and forms a stable adhesive structure, the two opposite side adhesive plates 6 are installed together by the fixing strip 10 to form a stable frame structure. This frame structure, together with the filter paper, is the replacement filter element structure that is mainly assembled in this process. The frame structure with filter paper is assembled inside the housing of the high-efficiency filter, and the two sides of the filter paper are sealed to form a stable seal with the outer frame. This makes it easier to replace the filter paper during disassembly and assembly compared to traditional methods. Since the corrugated edges are pre-sealed, leakage at the corrugated edges is less likely to occur, resulting in a higher assembly success rate and efficiency, and ensuring maintenance quality.

[0025] This invention provides an assembly method for a high-efficiency filter. Considering that when installing the side bonding plate 6, the adhesive filling the upright side bonding plate 6 is prone to sagging due to gravity, leading to uneven adhesive distribution, and if the adhesive film layer is too thin, it may not perfectly contact the corrugated edge of the filter paper to form sufficient seal, a porous sponge soaked in thermosetting adhesive can be filled into the bonding groove 602 before bonding the side bonding plate 6. In this way, the porous structure of the sponge can, to some extent, prevent the adhesive layer from sinking and causing uneven adhesive distribution. During the installation of the side bonding plate 6, the squeezing action of the corrugated edge of the filter paper causes the sponge to exude adhesive and cover the corrugated edge, thus facilitating the formation of a stable adhesive-covered structure. Further curing at this point further ensures the structural stability of the sealing adhesive layer and guarantees a good seal. The preferred thickness of the sponge layer is 3-5 mm.

[0026] The present invention provides an assembly method for a high-efficiency filter. To avoid deformation of the side bonding plate 6 due to expansion during the curing process of thermosetting adhesive, which would affect the subsequent assembly of the fixing strip 10, the side bonding plates 6 on both sides can be positioned during installation (this can be achieved by increasing the counterweight of the side bonding plates 6 to increase the maximum static friction, or by using a corresponding limiting mechanism to limit and hold the side bonding plates 6). After the thermosetting adhesive is cured by heating, the positioning of the side bonding plates 6 is then released, thereby ensuring the final product effect when the final product is shaped.

[0027] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
