Description

Technical Field

[0001] The invention relates to the technical field of capacitor manufacturing, in particular to an air blowing device for surface treatment of capacitor aluminum foil. Background Art

[0002] The internal core of the stacked capacitor is composed of several stacked electrodes. During the manufacturing process, each aluminum foil electrode is formed into an oxide film on the surface, impregnated with electrolyte chemical polymers to form a conductive polymer layer, and then coated with carbon paste to form a carbon coating, and coated with silver paste to form a silver paste coating. After the aluminum foil electrode is impregnated with the compound liquid, the excess compound liquid needs to be removed and dried. After the aluminum foil is impregnated with carbon paste, the carbon paste attached to its surface needs to be flattened to obtain a carbon coating. After the aluminum foil is impregnated with silver paste, the silver paste attached to its surface needs to be flattened to obtain a silver paste coating. The conventional method used in the industry is to dry the aluminum foil electrode after impregnation with the compound liquid, and to dry it naturally after impregnation with carbon paste and silver paste. During the drying or drying process, since the carbon paste and silver paste are in liquid form, vertical flow will occur, resulting in uneven thickness distribution of the carbon coating and silver coating on the surface of the aluminum foil electrode. After the aluminum foil is hung with carbon paste and silver paste, it needs to be blown to make the thickness uniform. Since the existing blowing knife air outlet pressure is uneven and not concentrated enough, it is impossible to perform precise blowing treatment on the product, resulting in excessive adhesion of carbon paste and silver paste on the surface of the aluminum foil and uneven coating distribution, which causes waste of resources and affects product performance. Summary of the Invention

[0032] The embodiments of the present invention are further described in detail with reference to the accompanying drawings: The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection of the present invention.

Thus, features defined as "first," "second," or "third" may explicitly or implicitly include one or more of such features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0035] In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "fixed," and "provided with" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0036] like Figure 1 As shown, the pressure regulating mechanism 1 is arranged on one side of the blowing mechanism 3; the pressure regulating mechanism 1 is composed of a pressure regulating component 101 and a base 102; the pressure regulating mechanism 1 is connected to the blowing mechanism 3 through an air pipe 1013; and one end of the blowing mechanism 3 is fixedly connected to the driving mechanism 2.

[0037] Specifically, the air inlet end of the pressure regulating mechanism 1 is connected to the boosting mechanism, which is used to supply pressurized gas to the pressure regulating mechanism 1. The air pressure is regulated by the pressure regulating assembly 101 in the pressure regulating mechanism 1, and each pressure regulating assembly is independently controlled. Each pressure regulating assembly is separately connected to an air pipe 1013, which is connected to the air inlet interface 302 in the blowing mechanism 3 through the air pipe 1013. Each pressure regulating assembly independently controls the air pressure of an air pipe 1013, achieving the purpose of independent and precise air pressure. The end of the blowing mechanism 3 is fixedly connected to the drive mechanism 2, which drives the blowing mechanism 3 to move longitudinally and laterally.

[0038] The driving mechanism 2 includes a lifting component 201, a fixed frame 202, and a transmission component 203; the lifting component 201 is installed vertically downward on the fixed frame 202, the output end of the lifting component 201 is fixedly connected to one end of the blowing mechanism 3, and the end of the fixed frame 202 away from the lifting component 201 is fixedly connected to the transmission component 203. The transmission component 203 can drive the fixed frame 202, the lifting component 201, and the blowing mechanism 3 to move together in the horizontal plane.

[0039] like Figure 1As shown, the blowing mechanism 3 includes a cross bar 301, an air inlet interface 302, a sealing cover plate 303, a blowing knife 304, a first air blowing port 305, and a second air blowing port 306; the upper end surface of the cross bar 301 is provided with a plurality of air inlet interfaces 302 at intervals along its length direction; the lower end surface of the cross bar 301 is provided with a plurality of air chambers 3011 at intervals along the length direction, and a first through hole 3012 leading to the air inlet interface 302 is opened inside the air chamber 3011, so that the air chamber 3011 and the air inlet interface 302 are connected as a whole.

[0040] Specifically, the lifting assembly 201 can be a cylinder or a motor. In this embodiment, a cylinder is used as the lifting drive. The lifting assembly 201 is driven to rise or fall in the vertical direction, so as to drive the blowing mechanism 3 to rise or fall in the vertical direction. When the blowing mechanism 3 descends, the blow blade 304 is inserted into one side of the iron bar inside the carrier 6. When the blowing mechanism 3 ascends, the blow blade 304 is driven to withdraw from the carrier 6. The transmission assembly 203 drives the blowing mechanism 3 so that the blowing mechanism 3 moves in the horizontal direction. During operation, the transmission assembly 203 can be a cylinder or a motor. In this embodiment, a motor is used as the driving force. The lifting assembly 201 and the transmission assembly 203 cooperate with each other to realize the longitudinal and lateral movement of the blowing mechanism 3.

[0041] like Figure 1 、 Figure 3 As shown, the pressure regulating assembly 101 includes a pressure regulating valve 1011, a pressure gauge 1012, and an air pipe 1013. Several pressure regulating assemblies 101 are arranged at intervals along the length direction of the upper end surface of the base 102. Each pressure regulating assembly 101 is connected to the blowing mechanism 3 by an independent air pipe 1013.

[0042] The upper end surface of the crossbar 301 of the air blowing mechanism 3 is provided with a plurality of air inlet ports 302 spaced apart along its length. Each air inlet port 302 is connected one-to-one to each pressure regulating assembly 101 in the pressure regulating mechanism 1 via a separate air pipe 1013. Each pressure regulating assembly 101 independently controls the air pressure of an air inlet port 302. A first through hole 3012 is provided within the air chamber 3011, leading to the air inlet port 302, thereby connecting the air chamber 3011 and the air inlet port 302 as a whole. This ensures that the air pressure in the air chambers 3011 of the same air inlet port 302 is the same.

[0043] The end face of the cross bar 301 on which the air chamber 3011 is opened is sealedly connected to the upper end face of the sealing cover plate 303; the lower end face of the sealing cover plate 303 away from the air chamber 3011 is provided with a plurality of blowing knives 304 at intervals along its length; the blowing knife 304 is provided with a first blowing port 305 and a second blowing port 306 at one end away from the sealing cover plate 303.

[0044] Each of the blowing blades (304) has two symmetrical second through holes 3031 formed inside along its length, one end of the second through hole 3031 extending to the upper end surface of the sealing cover plate 303 and communicating with the air chamber 3011; the second through hole 3031 extends away from the end of the sealing cover plate 303 to the end of the blowing blade 304 and communicates with the first blowing port 305 and the second blowing port 306 respectively;

[0045] Specifically, the crossbar 301 defines an air chamber 3011, which is sealed by the sealing cover plate 303 to form a closed air chamber 3011. One end of the air chamber 3011 communicates with the air inlet port 302 via a first through-hole 3012, and the other end communicates with a second through-hole 3031 extending through the upper end surface of the sealing cover plate 303. This allows the first and second air ports 305, 306 at the ends of the blow blades 304 to be connected to the air chamber 3011. The gas within the air chamber 3011 is distributed to the first and second air ports 305, 306 at the same pressure. The same air chamber 3011 can simultaneously control the airflow of multiple blow blades 304, and the blow blades 304 under the same air chamber 3011 constitute a blow blade 304 group.

[0046] like Figure 8 As shown, the moving trajectory of the blowing knife 304 is to first reach down to the gap between two adjacent iron bars 603 in the carrier 6 so that the first blowing port 305 and the second blowing port 306 are aligned with the side surface of the aluminum foil 7, and then the blowing knife 304 moves along the length direction of the iron bar 603 to blow air on the side surface of the aluminum foil 7.

[0047] like Figure 8 As shown, the first air blowing port 305 and the second air blowing port 306 are respectively provided with an elbow 3051. The first air blowing port 305 and the second air blowing port 306 are symmetrically arranged opposite to each other, so that the first air blowing port 305 and the second air blowing port 306 are respectively facing the side of the adjacent aluminum foil 7, and the bending angle of the elbow 3051 is 10 to 90 degrees.

[0048] like Figure 1 As shown, a feed track 4 is provided below the blowing mechanism 3, and a carrier 6 for storing the iron bars 603 is placed on the upper end surface of the feed track 4. Figure 1 、 Figure 7 As shown, the carrier 6 includes a rectangular frame 601, limiting teeth 602, and an iron bar 603. The limiting teeth 602 are spaced apart on opposite sides of the rectangular frame 601. The iron bar 603 is installed in the gap between the limiting teeth 602. Several aluminum foils 7 are vertically fixed on the side of the iron bar 603.

[0049] Specifically, the blowing blades 304 in the blowing mechanism 3 are arranged at intervals to form a rake-like structure. The blowing blades 304 in the blowing mechanism 3 are divided into several blowing blade groups. The blowing blades 304 connected to each air chamber 3011 are a blowing blade group. When working, each blowing blade 304 is inserted into the gap between two adjacent iron bars 603 in the carrier 6. The first blowing port 305 and the second blowing port 306 are respectively provided with an elbow 3051. The bending angle of the elbow 3051 is 10 to 90 degrees, so that the first blowing port 305 and the second blowing port 306 are respectively provided with an elbow 3051. 05. The second air blowing port 306 is directed toward the aluminum foil 7 on the side of the two adjacent iron bars 603. The bending angle is set, and the blowing range can be controlled by adjusting the angle. The pressure-regulated airflow is directly blown toward the surface of the aluminum foil 7 through the first air blowing port 305 and the second air blowing port 306, blowing the electrolyte or carbon paste or silver paste attached to the surface of the aluminum foil 7 flat, and blowing away the excess electrolyte or carbon paste or silver paste to prevent the carbon paste and silver paste from flowing vertically, thereby saving resources and flattening the coating.

[0050] During operation, the booster mechanism provides high-pressure gas, which is adjusted to a preset air pressure by the pressure regulating mechanism 1. The carrier 6 equipped with the iron bar 603 moves to the bottom of the blowing mechanism 3 through the feed track 4 under the blowing mechanism 3. The position is detected by the detector 5. After determining that the carrier 6 has entered the predetermined position, the lifting component 201 in the driving mechanism 2 pushes the blowing mechanism 3 downward so that the blowing knife 304 is inserted into the carrier 6. When the blowing mechanism 3 descends, the blowing knife 304 is inserted into one side of the iron bar 603 inside the carrier 6. The first blowing port 305 and the second blowing port 306 are respectively aligned with the aluminum foil 7 on one side of the iron bar 603. When the blowing knife 304 completes its downward movement, the transmission component 20 in the driving mechanism 2 is immediately driven. 3 drives the blowing mechanism 3 to move along the length direction of the iron bar 603, and the high-pressure airflows from the first blowing port 305 and the second blowing port 306 are blown toward the surface of the aluminum foil 7. The movement trajectory of the blowing knife 304 in the horizontal plane is from the front end to the rear end of the iron bar 603 until the surfaces of all the aluminum foils 7 on the iron bar 603 are blown once. After that, the lifting component 201 drives the blowing mechanism 3 to rise to a preset height, and the transmission component 203 drives the blowing mechanism 3 to reset, completing one blowing process and waiting for the next blowing instruction. The cycle is operated to solve the defect problem in the prior art that the thickness distribution of the carbon coating and the silver coating on the surface of the aluminum foil electrode is uneven due to the vertical flow phenomenon after the aluminum foil surface is impregnated with carbon paste and silver paste.

[0051] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention is not limited to the embodiments described in the specific implementation methods. Any other implementation methods derived by those skilled in the art based on the technical solutions of the present invention also fall within the scope of protection of the present invention.
