Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to a dust filter device, an air conditioner, and assembly equipment and method for the dust filter device. Background Technology

[0002] Existing dust filters are supported by a flexible square mesh frame structure, utilizing the elastic deformation of the frame crossbars to adapt to the shape of the housing. Typically, the size of the dust filter is only suitable for the air inlet of one type of housing.

[0003] With the diversification of air conditioner product designs, the shapes of air inlets on existing air conditioner housings vary, and the widths of the air inlets are also different. Dust filter structures of the same size cannot adapt to the installation requirements of air inlets on different housings. Furthermore, the original dust filter is difficult to adjust in width. Each time the width of the air inlet on the housing is adjusted, a special mold needs to be developed for the frame structure of the dust filter, which increases production costs and reduces production efficiency. Summary of the Invention

[0004] This invention provides a dust filter device, an air conditioner, and assembly equipment and method for the dust filter device, in order to solve the problem that the existing dust filter structure is not easy to adapt to the installation requirements of air inlets of different widths.

[0005] This invention provides a dust filter device, comprising:

[0006] A pair of flexible connecting rods are arranged opposite each other, and the flexible connecting rods are provided with at least two mounting slots at intervals. The mounting slots are located on opposite sides of the pair of flexible connecting rods and are arranged at intervals along the extension direction of the flexible connecting rods.

[0007] At least one filter unit, the filter unit including a support frame and a filter screen disposed on the support frame, wherein the middle portions of both ends of the support frame are respectively provided with connecting posts corresponding to the flexible connecting rod, and the connecting posts are inserted into the mounting groove.

[0009] According to a dust filter device provided by the present invention, the width of the support frame is greater than the spacing between adjacent mounting slots, and the adjacent support frames overlap.

[0010] According to the dust filter device provided by the present invention, a limiting structure is further included, the limiting structure being connected to adjacent filter units and used to provide a driving force to the adjacent filter units to move their adjacent sides closer to each other.

[0011] According to a dust filter device provided by the present invention, the limiting structure includes a first magnetic element and a second magnetic element, the first magnetic element and the second magnetic element are respectively placed on adjacent sides of two adjacent filter units, and the first magnetic element and the second magnetic element are arranged with opposite poles.

[0012] According to a dust filter device provided by the present invention, the limiting structure includes a first torsion spring and a second torsion spring, the first torsion spring and the second torsion spring being disposed on the connecting post of two adjacent filter units respectively, the first torsion spring and the second torsion spring being used to provide a torque to the corresponding filter unit, causing the filter unit to tend to move to one side closer to the adjacent side of the adjacent filter unit.

[0013] According to a dust filter device provided by the present invention, the limiting structure includes an elastic traction member, the two ends of which are respectively connected to the adjacent sides of the adjacent filter unit.

[0014] The present invention also provides an air conditioner, including the above-described dust filter device.

[0015] The present invention also provides an assembly apparatus for the above-mentioned dust filter device, comprising:

[0016] A positioning mechanism is used to position a pair of flexible connecting rods respectively, and to drive the pair of flexible connecting rods to move closer or further apart from each other;

[0017] A cutting mechanism for cutting a pair of flexible connecting rods to a preset length; and

[0018] The mounting mechanism is used to move the filter unit between a pair of flexible connecting rods and align the connecting post of the filter unit with the corresponding mounting slot.

[0019] The present invention also provides a method for assembling the above-mentioned dust filter device, comprising:

[0020] Position the flexible connecting rods so that a pair of flexible connecting rods face each other and are spaced a first preset distance apart;

[0021] Cut a pair of flexible connecting rods to a preset length;

[0022] Move the filter unit between a pair of flexible connecting rods and align the connecting post of the filter unit with the corresponding mounting slot;

[0023] Drive a pair of flexible connecting rods to move closer to each other until they are a second preset distance apart.

[0024] The dust filter device, air conditioner, and assembly equipment and method for the dust filter device provided by this invention are provided with a pair of flexible connecting rods and at least two mounting slots on the flexible connecting rods. The filter unit is installed between the pair of flexible rods through the mounting slots. The flexible connecting rods can be easily cut according to the width of the air inlet, and the number of filter units can be increased or decreased, thereby adapting to air inlets of different widths. This can effectively reduce the number of molds to be developed, reduce production costs, and improve production efficiency. In addition, since the filter unit is connected to the flexible connecting rod through the cooperation of the connecting column and the mounting slot, the filter unit can be easily adjusted at the bending position of the air inlet of the housing to adapt to the bending state of the flexible connecting rod, thus having better applicability.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0045] The following is combined Figures 1 to 6 This invention describes a dust filter device that can be installed at the air inlet of an air conditioner casing to filter the incoming air. Of course, the dust filter device in this embodiment can also be installed in other devices requiring filtration; no specific limitation is made here.

[0046] like Figure 1 and Figure 2 As shown, the dust filter device according to an embodiment of the present invention includes a pair of flexible connecting rods 100 and at least one filter unit 200; the pair of flexible connecting rods 100 are arranged opposite to each other, and the flexible connecting rods 100 are provided with at least two mounting grooves 110 at intervals. The mounting grooves 110 are located on opposite sides of the pair of flexible connecting rods 100 and are arranged at intervals along the extending direction of the flexible connecting rods 100; the filter unit 200 includes a support frame 210 and a filter 220 disposed on the support frame 210. The middle portions of both ends of the support frame 210 are respectively provided with connecting posts 230 corresponding to the flexible connecting rods 100, and the connecting posts 230 are inserted into the mounting grooves 110.

[0047] In this embodiment, a pair of flexible connecting rods 100 can be installed on two opposite sides of the air inlet of the air conditioner housing. For example, one flexible connecting rod 100 can be installed on the upper side of the air inlet, and the other flexible connecting rod 100 can be installed on the lower side of the air inlet; or, one flexible connecting rod 100 can be installed on the left side of the air inlet, and the other flexible connecting rod 100 can be installed on the right side of the air inlet. For ease of description, the following description uses a pair of flexible connecting rods 100 arranged vertically, with one flexible connecting rod 100 installed on the upper side of the air inlet and the other flexible connecting rod 100 installed on the lower side of the air inlet as an example.

[0048] The upper flexible connecting rod 100 has a mounting groove 110 on its lower side and a mounting groove 110 on its upper side. Furthermore, in the vertical direction, the mounting groove 110 of the upper flexible connecting rod 100 is aligned with the mounting groove 110 of the lower flexible connecting rod 100.

[0049] A connecting post 230 is provided at the middle of the upper end and the middle of the lower end of the support frame 210. The diameter of the connecting post 230 is less than or equal to the diameter of the mounting groove 110. The connecting post 230 at the upper end of the support frame 210 is inserted into the mounting groove 110 of the upper flexible connecting rod 100, and the connecting post 230 at the lower end of the support frame 210 is inserted into the mounting groove 110 of the lower flexible connecting rod 100.

[0050] The support frame 210 can adopt a square frame structure. Preferably, the support frame 210 adopts a rectangular frame structure with its length direction perpendicular to the flexible connecting rod 100.

[0051] The shape of the filter screen 220 is adapted to the shape of the support frame 210, and the edge of the filter screen 220 is fixedly connected to the frame of the support frame 210 and is supported and shaped by the support frame 210.

[0052] The dust filter device of the present invention has a flexible connecting rod 100 that can bend and deform to adapt to the shape of the shell. Furthermore, since the support frame 210 is connected to the flexible connecting rod 100 through the connecting column 230, the angle can be adjusted with the bending and rotation of the flexible connecting rod 100, thus having better applicability.

[0053] Optionally, an anti-detachment ring 231 is provided on the outer side of the connecting column 230, and an anti-detachment groove 120 adapted to the anti-detachment ring 231 is provided on the side wall of the mounting groove 110. When the connecting column 230 is located in the mounting groove 110, the anti-detachment ring 231 is located in the anti-detachment groove 120. Thus, while ensuring that the filter screen unit 200 can rotate relative to the flexible connecting rod 100, the resistance to the separation of the filter screen unit 200 from the flexible connecting rod 100 can be increased, so that the dust filter device forms a stable whole and is easier to install.

[0054] It is worth noting that even without the anti-detachment ring 231 and the anti-detachment groove 120, the diameter of the connecting post 230 can be larger than the inner diameter of the anti-detachment groove 120 to achieve the anti-detachment function.

[0055] Optionally, the support frame 210 is made of ABS resin, and the flexible connecting rod 100 is made of flexible polypropylene. Combining the flexible connection structure with the rigid frame structure forms a stable support structure with deformability.

[0056] In some embodiments of the present invention, there are two or more filter units 200, and each filter unit 200 is arranged sequentially along the flexible connecting rod 100. Each filter unit 200 works together to perform the filtering function. By increasing the number of filter units 200, the size of a single filter unit 200 under the same filtering area can be reduced, thereby giving the dust filter device better bending adaptability.

[0057] like Figure 3 As shown, in some alternative embodiments of the present invention, the width of the support frame 210 is greater than the spacing between adjacent mounting slots 110, and the adjacent support frames 210 overlap and cooperate.

[0058] It is understandable that when the width of the support frame 210 is greater than the spacing between the adjacent mounting slots 110, the adjacent support frames 210 overlap in some areas. By setting them in a staggered manner, an angular difference can be generated between the adjacent support frames 210 while meeting the requirements of comprehensive filtration.

[0059] Optionally, the same-direction sides of each support frame 210 deflect in the same direction relative to the flexible support rod. For example, when the right side of one support frame 210 deflects to the left of the flexible support rod's length direction, the right side of the other support frames 210 also deflects to the left of the flexible support rod's length direction. This avoids interference between the support frames 210.

[0060] Combination Figure 4 , Figure 5 and Figure 6 In some embodiments of the present invention, the dust filter device further includes a limiting structure, which is connected to adjacent filter units 200 and is used to provide a driving force to bring adjacent filter units 200 closer together. It is worth noting that, in this embodiment, "adjacent side" refers to the side of adjacent filter units 200 that is close to each other. For example, between two adjacent filter units 200, the right side of the filter unit 200 on the left and the left side of the filter unit 200 on the right are adjacent sides.

[0061] In this embodiment of the invention, by setting a limiting structure, the tightness of the fit between adjacent filter units 200 can be ensured, and gaps can be avoided between adjacent sides of adjacent filter units 200, preventing some air from flowing out from the gap position and affecting the filtration effect.

[0062] The following are examples of several optional methods for limiting structures:

[0063] like Figure 4 As shown, in one alternative embodiment, the limiting structure includes a first magnetic element 240 and a second magnetic element 250, which are respectively placed on adjacent sides of two adjacent filter units 200, with the opposite poles of the first magnetic element 240 and the second magnetic element 250 facing each other.

[0064] Taking two adjacent filter units 200 arranged on the left and right as an example, the right side frame of the filter unit 200 on the left is provided with a first magnetic element 240, and the left side frame of the filter unit 200 on the right is provided with a second magnetic element 250. The opposite poles of the first magnetic element 240 and the second magnetic element 250 are arranged facing each other (for example, the N pole of the first magnetic element 240 and the S pole of the second magnetic element 250 are arranged facing each other). The first magnetic element 240 and the second magnetic element 250 attract each other, causing the right side frame of the filter unit 200 on the left and the left side frame of the filter unit 200 on the right to stick together.

[0065] Optionally, the two side frames of the support frame 210 are respectively provided with hidden grooves for installing the first magnetic component 240 and the second magnetic component 250.

[0066] like Figure 5 As shown, in another alternative embodiment, the limiting structure includes a first torsion spring 260 and a second torsion spring 270, which are respectively placed on the connecting posts 230 of two adjacent filter units 200. The first torsion spring 260 and the second torsion spring 270 are used to provide a torque to the corresponding filter unit 200 to make the filter unit 200 tend to move to one side closer to the adjacent side of the adjacent filter unit 200.

[0067] Optionally, the first torsion spring 260 and the second torsion spring 270 are respectively sleeved on the corresponding connecting post 230, and one end of the first torsion spring 260 and the second torsion spring 270 are connected to the corresponding support frame 210, and the other end is connected to the flexible support rod. The torque provided by the first torsion spring 260 to the corresponding support frame 210 is in the same direction as the torque provided by the second torsion spring 270 to the corresponding support frame 210.

[0068] Taking two adjacent filter units 200 arranged on the left and right as an example, the filter unit 200 on the left is provided with a first torsion spring 260, and the filter unit 200 on the right is provided with a second torsion spring 270. Both the first torsion spring 260 and the second torsion spring 270 provide clockwise torque, causing the corresponding filter unit 200 to rotate clockwise. The right side of the support frame 210 in the left filter unit 200 is located counterclockwise from the left side of the support frame 210 in the right filter unit 200. The torques provided by the first torsion spring 260 and the second torsion spring 270 cancel each other out, and make the right side of the support frame 210 in the left filter unit 200 and the left side of the support frame 210 in the right filter unit 200 fit together.

[0069] like Figure 6 As shown, in another alternative embodiment, the limiting structure includes an elastic traction member 280, the two ends of which are respectively connected to the adjacent sides of the adjacent filter unit 200.

[0070] Taking two adjacent filter units 200 arranged on the left and right as an example, one end of the elastic traction member 280 is connected to the right side frame of the left filter unit 200, and the other end is connected to the left side frame of the right filter unit 200. Under the pulling force of the elastic traction member 280, the right side frame of the left filter unit 200 can be made to stick to the left side frame of the right filter unit 200.

[0071] Optionally, the elastic traction element 280 can be a tension spring or an elastic band, etc.

[0072] It is worth noting that the above solutions only provide a few exemplary options for limiting structures, and other solutions that can achieve the corresponding functions of the limiting structure should also be within the protection scope of the embodiments of the present invention.

[0073] This invention also provides an air conditioner, including the dust filter device described above.

[0074] Optionally, the air conditioner includes a housing with an air inlet and a dust filter device disposed at the air inlet.

[0075] Optionally, the housing has mounting grooves 110 on both sides of the air inlet, and the flexible connecting rod 100 is located in the corresponding mounting groove 110.

[0076] like Figure 7 and Figure 8 As shown, embodiments of the present invention also provide an assembly device for a dust filter screen, comprising:

[0077] The positioning mechanism 300 is used to position a pair of flexible connecting rods 100 respectively, and to drive the pair of flexible connecting rods 100 to move closer or further apart from each other;

[0078] Cutting mechanism 400 is used to cut a pair of flexible connecting rods 100 to a preset length; and

[0079] Mounting mechanism 500 is used to move filter unit 200 between a pair of flexible connecting rods 100 and align the connecting post 230 of filter unit 200 with the corresponding mounting groove 110.

[0080] In some embodiments of the present invention, the positioning mechanism 300 includes a first robotic arm 310, a second robotic arm 320, a first mounting plate 330, a second mounting plate 340, a plurality of first grippers 350, and a plurality of second grippers 360. The first robotic arm 310 and the second robotic arm 320 are arranged facing each other. The movable end of the first robotic arm 310 is fixed perpendicularly to the first mounting plate 330, and a plurality of first grippers 350 are provided on the first mounting plate 330. The movable end of the second robotic arm 320 is fixed perpendicularly to the second mounting plate 340, and a plurality of second grippers 360 are provided on the second mounting plate 340. The plurality of first grippers 350 located on the first mounting plate 330 can jointly grip one of the flexible connecting rods 100, and the plurality of second grippers 360 located on the second mounting plate 340 can jointly grip the other flexible connecting rod 100. At this time, a pair of flexible connecting rods 100 are parallel to the first mounting plate 330 and the second mounting plate 340 and face each other on the side where the mounting groove 110 is provided.

[0081] Optionally, the positioning mechanism 300 further includes a position adjustment drive (not shown in the figure), which corresponds one-to-one with the first gripper 350 and the second gripper 360. The adjustment drive is connected to the corresponding first gripper 350 or second gripper 360 and is used to adjust the position of the corresponding first gripper 350 or second gripper 360 along the length direction of the first mounting plate 330 and the second mounting plate 340.

[0082] Optionally, the position adjustment drive can be a cylinder or a telescopic motor.

[0083] In some embodiments of the present invention, the cutting mechanism 400 includes a third robotic arm 410 and a cutting component 420 disposed at the movable end of the third robotic arm 410. The cutting component 420 can be a cutting knife, scissors, or a chainsaw, etc. The third robotic arm 410 can move the cutting component 420 to a preset position for cutting, thereby cutting the flexible connecting rod 100 to a preset length.

[0084] In some embodiments of the present invention, the installation mechanism 500 includes a fourth robotic arm 510 and a third gripper 520 disposed at the end of the fourth robotic arm 510. The fourth robotic arm 510 is adapted to drive the third gripper 520 to move between the temporary storage position of the filter unit 200 and the installation position of the filter unit 200. The third gripper 520 is used to hold the filter unit 200.

[0085] It is understandable that since multiple filter units 200 can be provided, multiple mounting mechanisms 500 can be provided to clamp the filter units 200 respectively and move the filter units 200 to the corresponding positions. Alternatively, the mounting mechanism 500 can be provided with multiple second clamping claws, each second clamping claw is mounted on the same fourth robotic arm 510, and each second clamping claw is used to clamp one filter unit 200.

[0086] The assembly method of the dust filter device provided by the present invention is described below. The assembly method of the dust filter device described below can be referred to in correspondence with the assembly equipment of the dust filter device described above.

[0087] An assembly method for a dust filter device according to an embodiment of the present invention includes:

[0088] S100: Position the flexible connecting rod 100 so that a pair of flexible connecting rods 100 are positioned facing each other and separated by a first preset distance;

[0089] Step S100 specifically includes:

[0090] S110. The first mounting plate 330 is positioned and its orientation is adjusted by the first robotic arm 310 so that it is parallel to one of the flexible connecting rods 100 and located on the side of the flexible connecting rod 100 away from the mounting groove 110. The first robotic arm 310 drives the first mounting plate 330 to approach the flexible connecting rod 100 and clamps the flexible connecting rod 100 together with each of the first grippers 350. The second mounting plate 340 is positioned and its orientation is adjusted by the second robotic arm 320 so that it is parallel to the other flexible connecting rod 100 and located on the side of the flexible connecting rod 100 away from the mounting groove 110. The second robotic arm 320 drives the second mounting plate 340 to approach the flexible connecting rod 100 and clamps the flexible connecting rod 100 together with each of the second grippers 360.

[0091] S120. The first mounting plate 330 is adjusted by the first robotic arm 310, and the second mounting plate 340 is adjusted by the second robotic arm 320, so that the pair of flexible connecting rods 100 are parallel to each other and separated by a first preset distance, and the sides of the pair of flexible connecting rods 100 with mounting grooves 110 face each other.

[0092] The first preset distance is greater than or equal to the distance between the opposite ends of the two connecting posts 230 placed at both ends of the filter unit 200.

[0093] Optionally, before step S110, step S100 further includes:

[0094] S110' Adjust the position of the first gripper 350 and the second gripper 360 by adjusting the position drive.

[0095] Optionally, adjusting the positions of the first gripper 350 and the second gripper 360 by adjusting the position adjustment drive includes: placing two adjacent first grippers 350 on both sides of the corresponding flexible connecting rod 100 cutting position by adjusting the drive, and placing two adjacent second grippers 360 on both sides of the corresponding flexible connecting rod 100 cutting position by adjusting the drive.

[0096] S200, Cut a pair of flexible connecting rods 100 to a preset length;

[0097] The third robotic arm 410 moves the cutting piece 420 to the cutting position of the flexible connecting rod 100 and cuts the flexible connecting rod 100 so that the remaining length of the flexible connecting rod 100 is the preset length.

[0098] S300: Move the filter unit 200 between a pair of flexible connecting rods 100 and align the connecting post 230 of the filter unit 200 with the corresponding mounting groove 110.

[0099] Step S300 specifically includes:

[0100] S310, The third gripper 520 is moved to the temporary storage position of the filter unit 200 by the fourth robotic arm 510, and the filter unit 200 is gripped by the third gripper 520.

[0101] S320, the third gripper 520 is moved to the installation position of the filter unit 200 by the fourth robotic arm 510, so that the connecting post 230 of the filter unit 200 is aligned with the corresponding mounting groove 110.
