[0024] Before further describing the present invention in detail, the structure and processing flow of the breathable tab are described:

[0025] like Figure 1 As shown, the breathable tab consists of a tab sheet, a breathable filler disposed in the tab sheet's through-holes, and tab glue covering the tab sheet. Furthermore, the tab glue cover has through-holes for the breathable filler. The tab sheet is a conductive substrate made of metal. The breathable filler can be a composite of a water-absorbing material and a foam substrate.

[0026] The process of manufacturing breathable tabs includes: punching the tab sheet to form a through hole, fixing a breathable filler in the through hole, and finally applying tab glue to seal the through hole with the breathable filler.

[0027] To facilitate understanding of the embodiments of this application, first Figures 2 to 4 Detailed description. Figures 2 to 4 The fully automatic production equipment of a breathable tab in an embodiment of the present invention is shown. The fully automatic production equipment of a breathable tab in this embodiment includes:

[0028] Loading station 1, feeding station 2, slicing station 3 and the tab processing section with the introduction of a ring guide;

[0029] Among them, the loading station 1 is used to place the tab coil; the feeding station 2 is used to feed the tab coil into the slicing station 3; the slicing station is used to cut the tab coil to a set size to obtain tab sheets; the tab processing section is used to perform the punching operation of the tab sheet, the filling operation of the breathable filler, the fixing operation of the breathable filler, the coating operation of the tab glue, the repeated hot pressing and fusion operation and the tab detection operation in sequence with the cooperation of the annular guide rail to obtain the final breathable tab.

[0030] It should be understood that the tab coil is made of metal and is the raw material for the tab sheet. Those skilled in the art can set the size of the tab sheet according to actual process requirements, so that the slicing station can cut the tab coil according to the set tab sheet size.

[0031] In one embodiment, if Figure 3 as well as Figure 4 As shown, the tab processing section includes: a punching station 6 equidistantly arranged around the annular guide rail 5, a filler loading station, a first shaping station 9, a glue coating station 10, a second shaping station 11, a third shaping station 12, a first tab inspection station 13 and a second tab inspection station 14.

[0032] In one embodiment, if Figures 1 to 4 As shown, the punching station 6 is used to punch holes in the tabs to form through holes in the tabs.

[0033] In one embodiment, if Figures 1 to 4As shown, the filler loading station is equipped with a flexible vibrating plate 8 and a robotic arm 7. The flexible vibrating plate 8 is pre-placed with breathable filler, and the robotic arm 7 is used to evenly fill the breathable filler into the through-holes of the tabs. It should be understood that even filling refers to filling gaps, grooves, or uneven areas on the surface of an object to achieve a smooth and uniform surface.

[0034] In one embodiment, the robotic arm is a four-axis Scara robot with a vision positioning system.

[0035] In one embodiment, if Figures 1 to 4 As shown, the first shaping station 9 is used to secure the breathable filler in the through-holes of the tab; the adhesive coating station 10 is used to apply tab adhesive to the top and bottom surfaces of the tab to which the breathable filler is attached. Specifically, the first shaping station utilizes a hot press or hot pressing equipment, which is used to heat and pressurize specific areas of a material or product. It is typically equipped with a heating device, a pressure-applying device, and a platform or mold for placing the item to be processed.

[0036] In one embodiment, if Figures 2 to 4 As shown, the second shaping station 11 and the third shaping station 12 jointly perform repeated hot pressing and fusing on the glue-coated tabs. It should be understood that both the second shaping station and the third shaping station utilize hot pressing machines or hot pressing equipment. Repeated hot pressing and fusing refers to the process of hot pressing the glue-coated tabs by the second shaping equipment, followed by another hot pressing process by the third shaping equipment.

[0037] In one embodiment, if Figures 2 to 4 As shown, the first tab inspection station 13 and the second tab inspection station 14 jointly perform the tab inspection operation; wherein the first tab inspection station 13 is used to inspect the top surface of the tab; the second tab inspection station 14 is used to inspect the bottom surface of the tab. For example, Figure 1 The top surface of the tab is shown, with the bottom surface of the tab opposite the top surface.

[0038] In a specific embodiment, both the first tab inspection station and the second tab inspection station use CCD inspection equipment.

[0039] In one embodiment, if Figure 3 as well as Figure 4As shown, a plurality of transport structures 51 are provided at the station spacing of the tab processing section on the annular guide rail 5; wherein, a tab sheet will be placed on each transport structure 51 before it moves to the punching station 6, and the transport structure 51 will move in sequence to the punching station 6, the filler loading station, the first shaping station 9, the glue coating station 10, the second shaping station 11, the third shaping station 12, the first tab detection station 13 and the second tab detection station 14, so that each station can perform corresponding processing on the tab sheet. Specifically, since the stations of the tab processing section are arranged around the annular guide rail and at equal intervals, the station spacing of the tab processing section refers to the spacing between any two adjacent stations. By setting each transport structure according to the station spacing of the tab processing section, when each transport structure moves from one station to the next, the two adjacent transport structures of the transport structure also move to the corresponding station, so as to facilitate the fully automatic processing of multiple breathable tabs.

[0040] In one embodiment, the transport structure is a ring-shaped robot.

[0041] In one embodiment, if Figure 3 as well as Figure 4 As shown, the annular guide rail 5 is equipped with a tab sheet handling robot arm 4 ; wherein, the tab sheet handling robot arm 4 is used to transport the tab sheet from the slicing station 3 to the corresponding handling structure 51 .

[0042] In one embodiment, the tab handling robot is a four-axis Scara robot.

[0043] In one embodiment, if Figure 3 as well as Figure 4 As shown, the fully automatic production equipment for the breathable tab further includes: a packaging station 16 for packaging the final breathable tab.

[0044] In one embodiment, the packaging station 16 is equipped with a packaging robot 15 .

[0045] In one embodiment, the packaging robot is a three-axis robot.

[0046] The following will be combined with the attached Figure 2 To the attached Figure 4 , explaining the fully automated production process of breathable tabs:

[0047] The tab coil is placed on the loading station 1 in advance, and the feeding station 2 feeds the tab coil into the slicing station 3 through the servo control system. The slicing station 3 cuts the tab sheet according to the set tab sheet size to obtain the tab sheet.

[0048] Furthermore, the tab sheet transporting robot arm 4 places a tab sheet on the corresponding transport structure 51 of the annular guide rail 5. The tab sheet is clamped and fixed by the transport structure 51. The transport structure 51 first moves to the punching station 6, where the tab sheet is punched to form a through hole on the tab sheet. Then the transport structure 51 moves to the filler loading station, where the robot arm 7 of the filler loading station fills the breathable filler placed in the flexible vibration disk 8 into the through hole of the tab sheet, and fills the breathable filler evenly in the through hole of the tab sheet. Then the transport structure 51 moves to the first shaping station 9, where the first shaping station 9 fixes the breathable filler in the through hole of the tab sheet and forms a complete plane (the surface of the tab sheet is consistent with that of the breathable filler). Then the transport structure 51 moves to the glue coating station 10, where the tab glue is covered on the top and bottom surfaces of the tab sheet with the breathable filler fixed. After that, the transport structure 51 passes through the second shaping station 11 and the third shaping station 12 in sequence for repeated hot pressing and fusion to obtain a preliminary breathable tab. The transport structure 51 moves the preliminary tab sheet to the first tab inspection station to inspect the top surface of the preliminary tab sheet, and then transports it to the second tab inspection station to inspect the bottom surface of the preliminary tab sheet to obtain the final breathable tab.

[0049] It should be noted that the processing process of the existing tab production equipment is as follows: the raw materials are loaded into the loading station in the form of a roll, and then enter the pressing station and the gluing station in sequence through the guide station. The upper and lower glue of the tab are then passed through the material by mechanical fingers, and pressed at the gluing station to combine the tab glue with the metal. Then, the tab passes through the exhaust station, the fusion station, and the shaping station in sequence to ensure that the product meets the performance requirements. After passing through the cutting station, it is cut according to the set specifications. Therefore, the existing tab production equipment sequentially coats glue and fuses the tab coil. After the fusion is completed, it is sliced ​​to obtain the final tab. However, during the processing of breathable tabs, the tab coil needs to be cut first, and only then can punching, fixing the breathable filler, and gluing the tab glue be performed in sequence. Therefore, the strip feeding method used by the existing tab production equipment, which uses a servo clamp to clamp the strip and move it back and forth, cannot be applied to the production of breathable tabs. In the embodiment of the present invention, the tab coil is first cut by a slicing station, and then the cut tab slices are sent to the tab processing section introduced with an annular guide rail by a robotic arm to perform operations such as punching, fixing of breathable fillers, and coating of tab glue in sequence, thereby ensuring that each processing step can be completed normally after the tab coil is cut.

Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
