The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] See also Figures 1 to 3 A filter element coating device according to an embodiment of the utility model comprises: a machine base 100, on which is provided an assembly station for placing a cylindrical filter element 10 and enabling the cylindrical filter element 10 to rotate around its axis; a storage platform 200, which is arranged at one side of the assembly station and is used to place a filter membrane 20 to be coated; a welding assembly 300, which is movably arranged at the machine base 100 and can be moved to heat-press both side edges of the filter membrane 20 onto the cylindrical filter element 10 respectively; a driving mechanism, which is arranged at the machine base 100 and can drive the cylindrical filter element 10 to rotate around its axis; a positioning mechanism 400, which is movably arranged at the machine base 100 and can fix the filter membrane 20 to the storage platform 200 to prevent the filter membrane 20 from adhering to the welding assembly 300.

[0028] When it is necessary to wrap the filter membrane 20 on the outer wall of the cylindrical filter element 10, the filter membrane 20 to be coated is placed on the storage platform 200, and the welding assembly 300 hot-presses one side edge of the filter membrane 20 to the outer wall of the cylindrical filter element 10. The filter membrane 20 is separated from the welding assembly 300 under the action of the positioning mechanism 400, and then the driving mechanism drives the cylindrical filter element 10 to rotate around its axis to roll up the filter membrane 20, and then the welding assembly 300 hot-presses the other side edge of the filter membrane 20 to the cylindrical filter element 10, thereby realizing automated assembly. The production efficiency of the filter membrane 20 coating is high, and the quality is stable and reliable. It should be noted that when the welding assembly 300 hot-presses one side edge of the filter membrane 20 to the outer wall of the cylindrical filter element 10, the bonding force between the filter membrane 20 and the welding assembly 300 may be greater than the bonding force between the filter membrane 20 and the cylindrical filter element 10, resulting in the inability to reel in the filter membrane 20 when the cylindrical filter element 10 rotates. Therefore, the driving mechanism can fix the filter membrane 20 to the placement platform 200, and then drive the welding assembly 300 and the cylindrical filter element 10 to undergo relative displacement, thereby preventing the filter membrane 20 from adhering to the welding assembly 300, thereby ensuring that the cylindrical filter element 10 rotates around its axis to smoothly reel in the filter membrane 20.

[0029] See also Figure 1 and Figure 2 In some embodiments of the utility model, the base 100 is rotatably provided with a first rotating roller 110 and a second rotating roller 120 which are parallel to each other and spaced apart. The assembly station is defined between the first rotating roller 110 and the second rotating roller 120. The driving mechanism can drive the first rotating roller 110 and the second rotating roller 120 to rotate in the same direction to drive the cylindrical filter element 10 to rotate around its axis. It can be understood that the cylindrical filter element 10 has a cylindrical shape. When the cylindrical filter element 10 is placed on the assembly station, it contacts the outer peripheral walls of the first rotating roller 110 and the second rotating roller 120 at the same time. The driving mechanism drives the first rotating roller 110 and / or the second rotating roller 120 to rotate, which can drive the cylindrical filter element 10 to rotate around its axis. The structure is simple, and there is no need to accurately locate the axial direction of the cylindrical filter element 10, which is very convenient to use. Moreover, the method of placing the cylindrical filter element 10 between the first rotating roller 110 and the second rotating roller 120 can be applicable to cylindrical filter elements 10 of different diameters, has a wider scope of application, and can be directly used when dealing with cylindrical filter elements 10 of different diameters.

[0030] See also Figure 1 and Figure 2In some embodiments of the utility model, an adjustment mechanism 500 is connected between the storage platform 200 and the base 100 to drive the storage platform 200 to move up and down and left and right. It can be understood that the position of the storage platform 200 can be adjusted to the point where the filter membrane 20 can be tangent to the outer wall of the cylindrical filter element 10 by using the adjustment mechanism 500, and cylindrical filter elements 10 of different diameters can be matched, thereby expanding the versatility of the filter element coating device. Specifically, in the present embodiment, the adjustment mechanism 500 includes a translation slider that can move horizontally left and right relative to the base 100 and a lifting slider that can move up and down relative to the translation slider, and the lifting slider is connected to the bottom of the storage platform 200. Among them, the translation slider and the base 100, and the lifting slider and the translation slider are fixed by fastening screws passing through the long holes to achieve position adjustment, which will not be further described here.

[0031] See also Figure 1 In some embodiments of the utility model, the welding assembly 300 includes a lifting seat 310 movably arranged above the assembly station, a hot pressing roller 320 parallel to the first rotating roller 110 and the second rotating roller 120 is rotatably arranged on the lifting seat 310, a heating module is arranged inside the hot pressing roller 320, and the driving mechanism includes a first driver 610 driving the hot pressing roller 320 to rotate, and the hot pressing roller 320 abuts against the outer peripheral wall of the cylindrical filter element 10 to drive the cylindrical filter element 10 to rotate toward each other. It can be understood that when the hot pressing roller 320 abuts against the cylindrical filter element 10, the first rotating roller 110, the second rotating roller 120 and the hot pressing roller 320 simultaneously contact the outer peripheral wall of the cylindrical filter element 10 to form three non-collinear support points for the cylindrical filter element 10, which can prevent the cylindrical filter element 10 from jumping, and the hot pressing roller 320 can drive the cylindrical filter element 10 to rotate through friction when rotating. It should be noted that the filter membrane 20 is generally made of non-woven fabric, and the interior of the non-woven fabric contains colloid that can be heated and melted. When the lifting seat 310 moves downward until the hot pressure roller 320 is against the surface of the cylindrical filter element 10, the colloid inside the filter membrane 20 melts and adheres to the hot pressure roller 320 and the cylindrical filter element 10. At this time, the positioning mechanism 400 fixes the filter membrane 20 on the storage platform 200, and then the first driver 610 drives the hot pressure roller 320 to rotate a certain angle. During this process, the cylindrical filter element 10 and the filter membrane 20 thereon remain stationary, so that the hot pressure roller 320 rotates relative to the filter membrane 20 to prevent the filter membrane 20 from sticking to the hot pressure roller 320. Then the positioning mechanism 400 loosens the filter membrane 20, and then the hot pressure roller 320 continues to rotate to drive the filter membrane 20 to wrap around the cylindrical filter element 10. Specifically, in this embodiment, the positioning mechanism 400 is composed of a lifting cylinder and a pressing block disposed at the output end of the lifting cylinder, and the pressing block presses the filter membrane 20 tightly against the upper surface of the placement platform 200 .

[0032] See also Figure 1 In some embodiments of the present invention, in order to reduce the friction between the first rotating roller 110, the second rotating roller 120 and the filter membrane 20 and avoid the hot pressing roller 320 slipping when driving the cylindrical filter element 10 to rotate, the driving mechanism also includes a second driver 620 connected to the first rotating roller 110 and / or the second rotating roller 120 to drive the first rotating roller 110 and the second rotating roller 120 to rotate in the same direction.

[0033] See also Figure 1 and Figure 3 In some embodiments of the utility model, an end positioning assembly 700 is provided on the base 100, and the end positioning assembly 700 includes a positioning member 710 for abutting against an end face of the cylindrical filter element 10, and the positioning member 710 is provided with a positioning needle 720 that can extend into the inner circumferential surface of the cylindrical filter element 10. It can be understood that the cylindrical filter element 10 placed at the assembly station needs to be positioned in the front-to-back direction to ensure that the filter membrane 20 can completely cover all positions in the length direction of the cylindrical filter element 10. Among them, when the worker or the manipulator abuts the end of the cylindrical filter element 10 against the positioning member 710, the positioning needle 720 abuts against the inner circumferential wall of the cylindrical filter element 10, thereby positioning the position of the cylindrical filter element 10 to ensure the coating effect of the filter membrane 20.

[0034] See also Figure 3 In some embodiments of the utility model, the positioning member 710 is connected to a cantilever member 730, and the cantilever member 730 has a rotating shaft member 740. The rotating shaft member 740 can be rotatably arranged on the base 100 to adjust the positions of the positioning member 710 and the positioning pin 720. The base 100 is provided with a locking assembly 750 that can lock or unlock the rotating shaft member 740. It can be understood that when the diameter size of the cylindrical filter element 10 changes, the height position of the positioning pin 720 also needs to change accordingly. When the above structure is used to adjust the position of the positioning pin 720, it is only necessary to first unlock the rotating shaft member 740 using the locking assembly 750, and then rotate the rotating shaft member 740 to make the cantilever member 730 swing up and down, and finally ensure that the positioning pin 720 is against the inner circumference of the cylindrical filter element 10, and then use the locking assembly 750 to lock the rotating shaft member 740. In this embodiment, the locking assembly 750 is a tightening screw, which will not be further described here.

[0035] See also Figure 2In some embodiments of the present invention, the upper surface of the storage platform 200 is provided with a plurality of vent holes 210 downwardly, and a gas chamber connected to all the vent holes 210 is provided inside the storage platform 200, and the gas chamber is connected to a vacuum pump to adsorb the filter membrane 20 on the upper surface of the storage platform 200. When the vacuum pump extracts the gas in the gas chamber to the outside, the filter membrane 20 can be adsorbed by the plurality of vent holes 210 so that the filter membrane 20 is attached to the surface of the storage platform 200, thereby preventing the filter membrane 20 from being misplaced.

[0036] See also Figure 1 and Figure 2 In some embodiments of the utility model, a limit plate 220 is detachably mounted on the storage platform 200, and the limit plate 220 is provided with a waist-shaped hole 221 extending in the left-right direction. The storage platform 200 is provided with at least one mounting hole opposite to the waist-shaped hole 221, and a bolt is passed through the waist-shaped hole 221 and connected to the mounting hole. It can be understood that the circumference of the filter membrane 20 required to be wound around the cylindrical filter element 10 of different diameters is different, so the position of the filter membrane 20 placed on the storage platform 200 in the left-right direction also needs to change accordingly. The above simple structure can be adjusted to adapt to cylindrical filter elements 10 of different diameters.

[0037] In some embodiments of the utility model, in order to meet the needs of automated production and further improve the working efficiency of the filter membrane 20 coating the cylindrical filter element 10, the filter element coating device also includes a membrane supply mechanism, the membrane supply mechanism includes a unwinding roller and a winding roller located on the front and rear sides of the storage platform 200, the filter membrane 20 is connected between the unwinding roller and the winding roller, the membrane supply mechanism also includes a punching mechanism located between the unwinding roller and the winding roller, the punching mechanism can punch and cut the filter membrane 20 into a preset shape and size.

[0038] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
