Description

Technical Field

[0001] The invention relates to the field of aluminum foil production, and in particular to a flattening device for aluminum foil surface production. Background Art

[0002] Aluminum electrolytic capacitor is a capacitor with positive and negative electrodes. Its basic structure includes a layer of anode aluminum foil, a layer of cathode aluminum foil, and a layer of liner paper soaked in electrolyte and a natural oxide film in the middle. These materials are wound in an overlapping manner. After the electrodes are soaked in electrolyte, they are sealed with aluminum shells and rubber covers. In capacitors, anode aluminum foil and cathode aluminum foil are the key parts of capacitors, and their quality directly affects the performance of capacitors. In particular, anode aluminum foil needs to be made of industrial high-purity aluminum to ensure the stability and reliability of the capacitor; in addition, the texture of the aluminum foil needs to be uniform to ensure the stable performance of the capacitor.

[0003] In order to make the texture of aluminum foil uniform, the aluminum foil blank needs to be leveled. Leveling requires the use of special machinery. The principle is to use multiple sets of rollers to apply pressure to the aluminum foil, gradually reducing the thickness difference and surface defects of the aluminum foil blank. Therefore, the performance of the leveling machine is particularly important for aluminum foil. However, since the aluminum foil is applied to the surface of the aluminum foil by the entire roller, the flatness of the roller has extremely high precision requirements, otherwise it will cause cracks, bridge edges, broken edges, wrinkles and other defects on the surface of the aluminum foil. The existing leveling machines do not have a better way to prevent or avoid the above characteristics. They can only be adjusted after encountering the corresponding problems. This not only affects the production efficiency of the aluminum foil, but also reduces the yield rate of the aluminum foil. Summary of the invention

[0004] The purpose of the present invention is to solve the problems in the background technology and provide a flattening device for aluminum foil production. The flattening device can monitor the flattening of the aluminum foil and adjust the flattening machine in time when defects are found, thereby ensuring the production efficiency of the aluminum foil.

[0005] The objective of the present invention is achieved through the following technical solutions:

DETAILED DESCRIPTION

[0028] Example

[0029] like Figure 1 to Figure 7 As shown, the flattening device for the production of aluminum foil provided in this embodiment includes an uncoiler, a flattening machine and a servo feeder. The uncoiler unwinds the aluminum material roll and transmits it to the flattening machine for flattening. The flattening machine is installed between the uncoiler and the servo feeder. After the flattening machine flattens the aluminum foil, the servo feeder sends it to the punching machine to punch and cut the aluminum foil into parts. In order to ensure the flatness of the aluminum foil after stamping, the flattening machine includes a frame 1, a flattening roller group 2, a flattening roller group 3 and a machine cover 4. The machine cover 4 is hinged on the surface of the frame 1. The flattening roller group 2 is installed on the surface of the frame 1 below the machine cover 4. The flattening roller group 3 is installed inside the machine cover 4. The flattening roller group 3 is parallel to the axis of the flattening roller group 2 and rotates in the opposite direction. The flattening roller group 3 and the flattening roller group 2 cooperate with each other to flatten the aluminum foil so that the aluminum foil meets the production needs. The side walls at both ends of the machine cover 4 are added The machine has a feed port and a discharge port adapted to a leveling roller group 3 and a leveling roller group 2. A cleaning device 6 is installed on the frame 1 and the cover 4 at the feed port. The cleaning device 6 is used to clean the surface of the aluminum foil to remove aluminum chips and oil stains attached to the aluminum foil that affect the flatness of the aluminum foil. A feeding roller is installed on the rear side of the cleaning device 6. The feeding roller can adjust the moving speed of the aluminum foil in the leveling machine. A trimming device 7 is installed on the frame 1 at the discharge port. The trimming device 7 is used to trim the burrs and edges of the aluminum foil to ensure the uniform quality of the aluminum foil.

[0030] In order to level the efficiency, Figure 2 , Figure 3As shown, the structure of the leveling roller group 2 and the leveling roller group 3 are similar, both of which include a roller 21, a support frame 22, a bearing seat 23, a screw 24, a support spring 25 and a drive motor 26. The multiple rollers 21 are parallel to each other and arranged in sequence. Support frames 22 are installed at both ends of the rollers 21. The bearing seat 23 is installed in the support frame 22. The support frame 22 is installed on the surface of the frame 1 or the bottom surface of the cover 4. The end of the roller 21 is connected to the corresponding bearing seat 23. The support frame 22 is vertically processed with a limit groove for the lifting of the bearing seat 23. The screw 24 is threadedly connected The screw 24 is connected in the limiting groove, and a limiting block 27 is installed at the lower part. Connecting wings 28 are processed on both sides of the bearing seat 23. The connecting wings 28 are processed with avoidance holes 29 for the screw 24 to pass through. The support spring 25 is set on the screw 24 between the limiting block 27 and the connecting wing 28. The output shaft of the driving motor 26 is connected to one end of the roller 21. The driving motor 26 can adopt conventional connection methods such as transmission chain and gear set. The height of the limiting block 27 can be adjusted through the screw 24, and then the force applied to the aluminum foil by the roller 21 can be adjusted to ensure the leveling effect.

[0031] In order to flatten the aluminum foil more conveniently, Figure 4 As shown, a heating roller 5 is also installed on the support frame 22 near the feed port, and the heating roller 5 includes a support shaft 51, an insulating layer 52, a capacitor coil layer 53, a thermal insulation layer 54, an alloy layer 55 and a conductive slip ring 56. The support shaft 51 is rotatably installed on the bearing seat 23, and a conductive slip ring 56 is installed at one end of the support shaft 51. The insulating layer 52, the capacitor coil layer 53, the thermal insulation layer 54 and the alloy layer 55 are sequentially wrapped around the outside of the support shaft 51. The aluminum foil can be heated by the heating roller 5, thereby improving the plasticity of the aluminum foil so that it can be more conveniently flattened.

[0032] In order to reduce the impact of external factors on the leveling effect of aluminum foil, such as Figure 5 As shown, the cleaning device 6 includes a spray rack 61, an electric roller brush 63 and an air jet device 64. The spray rack 61 is frame-shaped. The top and the inner part of the spray rack 61 are installed with spray pipes 62 arranged opposite to each other. Two groups of electric roller brushes 63 in the same vertical plane are installed on the spray rack 61 on the rear side of the spray pipe 62. The aluminum foil passes horizontally through the middle of the spray rack 61. The rotation direction of the electric roller brush 63 is opposite to the moving direction of the aluminum foil. The spray rack 61 on the side of the electric roller brush 63 away from the spray pipe 62 is installed with an air jet device 64. The air jet device 64 includes a plurality of high-pressure air nozzles installed on the spray rack 61 and an air compressor connected to the plurality of high-pressure air nozzles. The air outlet directions of the plurality of high-pressure air nozzles are toward the electric roller brush 63. The electric roller brush 63 can clean up aluminum chips, impurities, etc. attached to the surface of the aluminum foil. The spray liquid sprayed from the spray pipe 62 can improve the cleaning efficiency of oil stains. At the same time, the high-pressure air nozzle can dry the residual spray liquid to ensure that the aluminum foil can be leveled normally.

[0033] In order to detect the leveling effect of aluminum foil, Figure 1 As shown, the cover 4 and the frame 1 at the rear side of the cleaning device 6 and the frame 1 at the rear side of the discharge port are both installed with detection systems 8 arranged relatively to each other. The flattening effect of the aluminum foil can be directly observed by using two sets of detection systems 8, such as Figure 7 As shown, the detection system 8 includes a detection box 81, a laser generator 82 and an industrial camera 83. A through hole for the aluminum foil to pass through is processed in the middle of the detection box 81. The laser generator 82 and the industrial camera 83 are installed side by side at the top and bottom of the detection box 81. The laser emitter emits a laser beam toward the surface of the aluminum foil. The laser beam scans the surface of the aluminum foil. The laser beam will deviate or gather at uneven places. The industrial camera 83 then captures the laser feedback information and uploads it to the image processing system for comparison, thereby judging the leveling effect of the aluminum foil.

[0034] In order to avoid the edge of the aluminum foil from warping and other conditions that affect the quality, such as Figure 6 As shown, the trimming device 7 includes a waste bin 71 symmetrically installed on both sides of the roller 21 and a cutting edge 72 installed on the waste bin 71. The cross-section of the waste bin 71 is rectangular, and an avoidance opening 73 is processed on the side wall of the waste bin 71 close to the aluminum foil. The cutting edge 72 is installed on the inner wall of the waste bin 71 at the end of the avoidance opening 73. When the aluminum foil moves, the edge of the aluminum foil enters the avoidance opening 73 and contacts the cutting edge 72. The cutting edge 72 cuts the aluminum foil it contacts to ensure the consistent quality of the aluminum foil.

[0035] The method of using the present invention is:

[0036] First, the aluminum foil raw material is continuously sent to the leveling machine through the uncoiler. When being sent to the leveling machine, the aluminum foil first passes through the spray rack 61. At this time, the spray pipe 62 sprays the cleaning agent toward the surface of the aluminum foil, and then the electric roller brush 63 cleans the aluminum foil. Finally, the jet device 64 sprays it to dry the cleaning agent. Then the aluminum foil passes through the detection system 8 and enters the heating roller 5. The heating roller 5 heats the aluminum foil to soften the texture of the aluminum foil and make it more convenient to clean. Then, the aluminum foil enters between the leveling roller group 3 and the leveling roller group 2 for leveling. After the trimming device 7 trims the aluminum foil after leveling, the detection system 8 performs another detection to determine the leveling quality and the working status of each component of the leveling device. The leveled aluminum foil is transmitted to the servo feeder to be processed into parts.

[0037] The above is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any modification and replacement based on the technical solution and inventive concept provided by the present invention shall be included in the protection scope of the present invention. It should be noted that the structures or components illustrated in the drawings are not necessarily drawn to scale, and the present invention omits the description of known components and processing technologies and processes to avoid unnecessary limitation of the present invention.
