DETAILED DESCRIPTION

[0042] The application will be further described below in conjunction with the drawings. The following examples are only used to more clearly illustrate the technical solutions of the application, and cannot be used to limit the protection scope of the application.

In addition, the terms "first", "second" and the like are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second" and the like can explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0044] In the description of the present application, it needs to be understood that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium, or the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood through specific circumstances. Example one

[0045] The high-efficiency filter assembly device provided by the embodiment of the application provides a new filter paper assembly method, so that the core of the high-efficiency filter device of the customer can be replaced under the demand of the customer, the manual operation error can be reduced while the assembly efficiency is ensured, and the assembly efficiency and quality are better. In order to realize the structure and function of the device, the device is provided with an assembly line 1 for conveying the folded filter paper, and the assembly line 1 is sequentially provided with a glue coating assembly 2, a mesh plate placing assembly 3, a side plate assembling assembly 5 and a connecting strip assembling assembly 8 from upstream to downstream. The feeding position of the side plate assembling assembly 5 is used as a reference, and the upstream and downstream of the position are divided into a first section and a second section (which can be formed by two different conveying belt structures), and the feeding width of the second section of the assembly line 1 is less than the length of the filter paper, so that the filter paper can leak out the blank part at both ends after being conveyed to the second section of the assembly line 1, thereby facilitating subsequent assembly work.

[0046] The glue coating assembly 2 is configured to coat a glue layer at the wave peak position of the filter paper, and the specific structure is not limited here. Specifically, as a preferred embodiment, the glue coating assembly 2 can include a glue groove 201, a first action module 202 and a glue sheet 203, which can be referred to as shown in Figure 1 and Figure 2 The first action module 202 is used to drive the glue sheet 203 to reciprocate at the glue taking position of the glue groove 201 and the surface of the filter paper. The glue groove 201 inside should be filled with glue to be cured. The glue sheet 203 is used to adhere glue at the bottom position thereof by movement, and coat the adhered glue on the folded filter paper layer conveyed by the assembly line 1. Since only the highest part of the wave peak position of the filter paper can contact the glue film layer at the bottom of the glue sheet 203, the glue will only be adhered at the wave peak position. If the glue sheet 203 is a flat plate, the thickness of the glue layer may not be uniform during movement and the glue layer may easily drip. Therefore, as another preferred way, a turn-up can be provided outside the bottom surface of the glue sheet 203 to form a limiting frame structure for maintaining the glue. During the movement of the glue, the glue can be prevented from dripping from the outside of the glue sheet 203 due to excessive deviation of the glue to one side caused by acceleration. The size of the limiting frame structure should be greater than the size of the filter paper. The resistance provided by the turn-up can inhibit the dripping of the glue layer from the edge to a certain extent. In some other preferred embodiments, a scraper can be provided to remove the glue layer below the turn-up to prevent the glue from continuously dripping downward due to excessive glue taking. In this embodiment, the thickness of the glue film layer formed after the glue layer below the turn-up is removed is preferably between 2-3 mm, so as to realize stable glue taking action. Other preferred embodiments are not limited here.

[0047] The net plate placing assembly 3 is used to place the protective net 11 on the surface of the filter paper, and the adhesive layer at the peak position of the filter paper is contacted with the protective net 11 to form a bonding surface, so that the protective net 11 can form a stable connection state between the adhesive layer and the filter paper through the curing of the adhesive layer, thereby on the one hand, the filter paper can be protected, and on the other hand, the shape of the filter paper can be stabilized after the adhesive layer is cured (the adhesive layer can be cured in a limited state of the filter paper, and other modes are not limited here), as a preferred embodiment, the device includes a cross rail 12 capable of moving above the assembly line 1, and the net plate placing assembly 3 includes a first lifting drive 301 capable of moving along the extension direction of the cross rail 12, as shown in Figure 8 , wherein 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 a suction long groove, and the upper surface of the suction cup 302 is provided with a vacuum pipe 303 capable of communicating with the suction long groove, and the suction long groove is used to adsorb the porous protective net 11, and it needs to be noted that the position and negative pressure state of the suction cup 302 can meet the requirement of generating sufficient suction force at the suction point, 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;

[0048] The side plate assembly assembly 5 is used to provide a side bonding plate 6, as shown in Figure 10 and Figure 11 , the side bonding plate 6 includes a base body 601 and a bonding groove 602 provided on the base body 601, wherein the bonding groove 602 is capable of matching the size of the side edge of the folded filter paper and is filled with an adhesive layer, at this time, the side plate assembly assembly 5 is used to assemble the bonding groove 602 of the side bonding plate 6 corresponding to the two side edges of the filter paper respectively, and the specific action mode is not limited here, that is, the side plate assembly assembly 5 is used to assemble the side bonding plate 6 on both sides of the folded angle of the filter paper, so that the side bonding plate 6 can form a stable bonding connection with the filter paper and realize the sealing and curing action of the folded angle surface of the filter paper. Because the thickness of the adhesive film in the bonding groove 602 is too thin during assembly, it is easy to cause misbonding, and if the thickness of the adhesive film is too thick, it is easy to cause the adhesive to move downward before curing, resulting in uneven thickness, therefore, as a preferred embodiment, a sponge with a certain thickness adsorbed with an adhesive layer can be placed in the bonding groove 602, and the side edge of the filter paper can extrude the adhesive and contact the side edge of the filter paper when the sponge is extruded, and a stable connection and sealing state can be formed after the adhesive is cured, and the adhesive layer is not easy to leak under a certain thickness, and this assembly mode can be realized by manual cooperation with mechanical handling, so as to reduce the complexity of mechanical assembly and detection (position of installed sponge layer and detection of adhesive state);

[0049] The connecting strip assembly assembly 8 is used to install the fixing strip 10 on the two opposite base bodies 601, and the finally formed connecting structure can be referred to Figure 9As shown, the connecting strip assembly component 8 can adopt the mode of cooperation between the mechanical hand 801 and the material taking gripper 802 to realize the grabbing action of the fixed strip 10, and install the fixed strip 10 on the two side bonding plates 6, and finally realize the frame assembly of the fixed strip 10 through the locking structure, so as to form a replacement core structure with certain structural stability. This formed structure can be directly assembled in the inside of the high-efficiency filter with a corresponding shape during installation, and through sealing assembly, the structure can be directly used to clamp and seal the other two side edges of the filter paper, or artificial glue sealing can also save a lot of disassembly and assembly work. Since the sealing of the wave angle side is completed in advance, it is also helpful to improve the sealing performance after disassembly and replacement, and the output assembly structure is also relatively stable, which is beneficial to transportation.

[0050] In order to realize the automatic transportation operation of the assembly line, the side of the upstream position of the second section of the assembly line 1 is also provided with a jacking conveying line 14, as shown in Figure 1 and Figure 14 As shown, the jacking conveying line 14 includes a jacking mechanism 1401 and a receiving line 1402 located at the output end of the jacking mechanism 1401. The receiving line 1402 is used to receive the side bonding plate 6 assembled on the side of the filter paper, so that the side plate assembly component 5 can realize the holding action of the side bonding plate 6 in the uncured state through the holding action of the receiving line 1402 after the side bonding plate 6 is assembled. The second conveying line 13 for conveying the side bonding plate 6 is also arranged at the side of the downstream position of the second section of the assembly line 1, so that the second conveying line 13 can correspond to the conveying position of the receiving line 1402, so that the product can be accurately conveyed to the downstream position when the side bonding plate 6 is uncured. It should be noted that the receiving line 1402 should be lifted to avoid the assembly of the side plate assembly component 5, and the height of the conveying position should be matched with the position of the folded filter paper conveyed by the second section of the assembly line 1.

[0051] The high-efficiency filter assembly device provided by the embodiment of the application can accelerate the curing speed of the glue layer on the assembly line 1. The device also includes a heat curing assembly 4, the glue filled in the glue groove 201 is heat curing glue, and the heat curing assembly 4 includes a second lifting driving member 401 capable of moving along the extension direction of the horizontal rail 12, as shown in Figure 8As shown, the output end of the second lifting driving member 401 is provided with a positioning plate 402, and a blow pipe 403 capable of performing inclined blowing is assembled on the positioning plate 402, and the blow pipe 403 is used for blowing hot air to the surface of the folded filter paper, so that the protective net 11 placed on the surface of the filter paper can be quickly and the filter paper structure can be formed in a bonding state, thereby quickly realizing the stable setting of the filter paper structure, and the second lifting driving member 401 is arranged to be movable along the extension direction of the cross rail 12, thereby providing a wider blowing range, and since the first lifting driving member 301 is also arranged on the cross rail 12, the structure can be saved while high-efficiency operation is performed, and when the first lifting driving member 301 drives the suction cup 302 to take materials, the blow pipe 403 can be replaced to the working station to blow air, and the two are alternately operated, thereby effectively saving the structural space.

[0052] The embodiment of the present application provides an efficient filter assembly device, and specifically provides a structure of a side plate assembly component 5, and specifically, the side plate assembly component 5 is arranged to include a material taking table 501, a second action module 502 and a clamping assembly arranged at the output end of the second moving module, as shown in the figure.

Embodiment two

[0055] The embodiment of the application provides an efficient filter assembling method, which is used in rapid disassembly and replacement work of the efficient filter, can facilitate maintenance of customer equipment and ensure yield after product disassembly and replacement, and the efficient filter assembling method comprises the following steps.

[0056] The folded filter paper is glued at the wave crest position, the folded filter paper can be shaped into a wave crest shape through pre-gluing, and since it belongs to the prior art, details are not described here, the filter paper after pre-shaping has certain stability after conveying, and the structure collapse of the filter paper structure in the conveying process can be avoided, in some other embodiments, the structure form of the filter paper can be constrained through a limiting structure in the conveying process, and the design of the limiting structure is not limited here, and the stability of the filter paper form can be ensured when the protective net 11 is subsequently laid.

[0057] After the gluing action is completed, the protective net 11 is placed on the surface of the filter paper and the protective net 11 and the glue layer are bonded together, and the glue layer can adopt UV glue, heat-curing glue and the like. Since the protective net 11 shields the position of the bonding point after being laid, the UV curing is easily hindered, at this time, it is preferred that the glue is set as heat-curing glue, and the hot air is flowed on the surface of the folded filter paper, so that the curing effect of the glue is quickly realized;

[0058] After the filter paper and the protective net 11 form a stable bonding structure, the two side bonding plates 6 are bonded on both sides of the filter paper structure respectively through the bonding side bonding plate 6, so that the sealing action of the filter paper undulating edge position is realized. The bonding and curing of the glue can also adopt the form of heat-curing glue, and the specific heat-curing method can refer to the water film 705 flexible contact heating shown in the embodiment one. When the width of the water film 705 is limited, the overall structure of the side bonding plate 6 and the filter paper can be moved to realize the change of the contact position of the water film 705, so as to ensure the curing state of each gluing position;

[0059] After the glue is cured to form a stable bonding structure, the two opposite side bonding plates 6 are installed together through the fixing strip 10, so as to form a stable frame-shaped structure. The frame-shaped structure cooperates with the filter paper to form the replacement filter element structure which is the main assembly of this time;

[0060] The frame-shaped structure with the filter paper is assembled in the shell of the high-efficiency filter, and the edges of the two sides of the filter paper are edge-sealed to enable the filter paper structure to form a stable sealing structure with the outer frame. Compared with the traditional way, the disassembly and assembly are more convenient, and since the undulating edge position has been sealed in advance, the undulating edge sealing leakage problem is less likely to occur, and the assembly success rate and efficiency are better, thereby ensuring the maintenance quality.

[0061] The embodiment of the application provides a kind of assembly method of high-efficiency filter, when installing side bonding plate 6, the glue filled in the side bonding plate 6 that stands is prone to sag under the influence of gravity, leading to uneven distribution of glue, if the thickness of glue film layer is too thin, it is also easy to cause that glue layer cannot perfectly contact with the undulating edge position of filter paper to form enough gluing sealing, therefore when bonding side bonding plate 6, porous sponge with heat-curing glue adsorbed can be filled in bonding groove 602 first, then install side bonding plate 6 on the side of filter paper corresponding to porous sponge, in this way, the porous structure of sponge can avoid the sinking of glue layer to some extent, leading to uneven distribution of glue, and when installing side bonding plate 6, the extrusion of filter paper undulating edge to sponge leads to sponge extruding glue to cover undulating edge, so as to be more conducive to forming stable glue covering structure, and then through curing effect, it is more conducive to ensuring the structural stability of sealing glue layer, and is conducive to ensuring good sealing effect, and the thickness of sponge layer is preferably 3-5mm.

[0062] The high-efficiency filter assembling method provided by the embodiment of the present application can position the side bonding plates 6 on both sides when the side bonding plates 6 are installed (the positioning can be realized by increasing the weight of the side bonding plates 6 to increase the maximum static friction, or by using a corresponding limiting mechanism to limit and press the side bonding plates 6, etc.), and then the positioning of the side bonding plates 6 is released after the thermosetting glue is cured by heating, so that the final product effect when the final product is shaped is ensured.

[0063] The above only describes the preferred embodiments of the present application, and it should be noted that those skilled in the art can make several improvements and modifications without departing from the technical principles of the present application, and these improvements and modifications should also be considered as the protection scope of the present application.
