Description

Technical Field

[0001] This invention relates to the field of aluminum foil laser cutting, specifically to a laser cutting device for aluminum foil of aluminum electrolytic capacitors. Background Technology

[0002] Aluminum foil is a key material in the manufacture of aluminum electrolytic capacitors. It is mainly divided into anode aluminum foil and cathode aluminum foil. Anode aluminum foil is formed by anodizing to create an aluminum oxide insulating dielectric layer, which is used to store charge. Cathode aluminum foil is etched to increase the surface area and does not form an oxide film. It mainly serves as a conductive path to connect the electrolyte. The quality of the aluminum foil, the depth and uniformity of the etched holes, and the density of the oxide film directly determine the capacitance, withstand voltage, leakage current, and service life of the capacitor.

[0003] When processing aluminum foil, it needs to be laser-cut using a laser cutter to meet the requirements of high precision, high cleanliness, and special structures. Existing laser cutting devices mostly use conveyor belts to transport aluminum foil. The aluminum foil moves to the bottom of the laser cutting equipment. The conveyor belt has a mesh structure, which allows the air pump located below the conveyor belt to adsorb the aluminum foil before the laser cutting equipment cuts it. However, when cutting sheet-like aluminum foil, the airflow generated by the air pump will cause adsorption and pulling on one end of the adjacent aluminum foil, which can easily lead to the aluminum foil shifting position.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figures 1-8 The diagram shows a laser cutting device for aluminum foil of an aluminum electrolytic capacitor. It includes a base 1 and two symmetrically fixed support plates 2 on the top of the base 1. A transverse slide 3 is fixedly installed on the top of each support plate 2, and a longitudinal slide 4 is installed between the two transverse slides 3. A laser cutter 5 is installed on the outer side of the longitudinal slide 4. Multiple equidistant material placement frames 6 are arranged between the two support plates 2, and a grid 7 is fixedly installed on the inner side of each material placement frame 6. Aluminum foil can be placed on the grid 7 inside the material placement frame 6. The position of the laser cutter 5 is adjusted by the cooperation of the transverse slides 3 and the longitudinal slides 4, facilitating laser cutting of the aluminum foil on the grid 7. An air inlet hood 8 is arranged between the two support plates 2. A dust collection box 9 is installed on the outer side of one of the support plates 2, and the dust collection box 9 is connected to the air inlet hood 8 via a flexible hose. This allows the dust collection box 9 to adsorb the aluminum foil on the grid 7 of the air inlet hood 8 and clean impurities generated during the laser cutting process. The conveying mechanism includes two symmetrically arranged toothed conveyor belts 39 between two support plates 2. The toothed conveyor belts 39 can continuously convey multiple material boxes 6. The conveying mechanism also includes two symmetrically rotatably mounted drive rods 11 between the two support plates 2. A drive motor is mounted at one end of the drive rod 11, and the drive motor is fixedly mounted on the outside of the support plate 2, so that the drive motor drives the drive rod 11 to rotate. The drive rod 11 is located inside the two toothed conveyor belts 39. Two transmission wheels 12 are fixedly mounted on the outside of the drive rod 11, which respectively cooperate with the two toothed conveyor belts 39. When the drive rod 11 rotates, it can drive the toothed conveyor belts 39 to rotate through the transmission wheels 12. The top of the toothed conveyor belts 39 is fixedly mounted. A mounting belt 13 is installed, and U-shaped frames 14 are fixedly installed on both sides of the material placement frame 6. A mounting rod 15 is fixedly installed on the side of the U-shaped frame 14 away from the material placement frame 6. Mounting holes are opened on the outer side of the mounting belt 13, and the mounting rod 15 is fixedly installed in the mounting holes of the mounting belt 13. The conveyor belt 39 can drive the mounting belt 13 to rotate, causing the mounting belt 13 to move synchronously through the mounting rod 15. The mounting rod 15 drives the material placement frame 6 to move synchronously through the U-shaped frame 14, thus moving multiple material placement frames 6 sequentially below the laser cutter 5 and above the air inlet hood 8. A first contact plate 16 is fixedly installed at the bottom of the material placement frame 6. The size of the first contact plate 16 is larger than the size of the material placement frame 6. A second contact plate 17 is fixedly installed on the top of the hood 8. When the material placement frame 6 moves above the air intake hood 8, the first contact plate 16 at the bottom of the material placement frame 6 can contact the second contact plate 17 of the air intake hood 8, realizing the docking of the material placement frame 6 and the air intake hood 8. This facilitates the air intake hood 8 to adsorb and clean the aluminum foil on the grille 7, and also prevents adsorption and pulling on the aluminum foil on adjacent grilles 7. Two limiting rings 32 are fixedly installed on the outer side of the mounting rod 15, and the corresponding sides of the two limiting rings 32 contact the two sides of the mounting belt 13 respectively. The limiting rings 32 can provide positioning for the mounting rod 15 and prevent the mounting rod 15 from falling off the mounting belt 13. A return opening is provided at the bottom of the first contact plate 16. A pressure frame 33 is slidably installed on the inner side of the groove. Multiple springs 34 arranged in a rectangular array are fixedly installed between the top of the pressure frame 33 and the inner side of the groove. The bottom of the pressure frame 33 has a sloping structure, and the outer side of the second contact plate 17 has an arc-shaped structure. When the material frame 6 moves, it can drive the pressure frame 33 at the bottom of the first contact plate 16 to contact the outer side of the second contact plate 17, so that the outer side of the second contact plate 17 pushes the sloping surface of the pressure frame 33, pushes the pressure frame 33 into the groove of the first contact plate 16, and compresses the springs 34. Using the elasticity of the springs 34, the pressure frame 33 abuts against the top of the second contact plate 17, improving the sealing between the first contact plate 16 and the second contact plate 17.

[0022] Example 2: Please refer to Figures 2-8This embodiment further illustrates Example 1. The anti-collision mechanism shown in the figure includes four pulleys 10 symmetrically arranged on the outside of the material placement frame 6. The pulleys 10 can improve the stability of the movement of the material placement frame 6. The anti-collision mechanism also includes two guide plates 18 symmetrically arranged between the two support plates 2. Both ends of the guide plates 18 are arc-shaped structures. The outer sides of the pulleys 10 are in contact with the outer sides of the guide plates 18. Two symmetrically distributed positioning rods 19 are fixedly installed on both sides of the material placement frame 6. The end of the positioning rod 19 away from the material placement frame 6 is fixedly installed on the outside of the U-shaped frame 14. The outer side of the positioning rod 19 is sleeved with a support arm 20. The four pulleys 10 are rotatably installed on the four support plates 2. One end of each support arm 20 away from the positioning rod 19 has two symmetrically distributed coil springs 21 fixedly installed between the inner side of the support arm 20 and the outer side of the positioning rod 19. The elasticity of the coil springs 21 causes the support arm 20 to drive the pulley 10 to abut against the outer side of the guide plate 18, providing auxiliary support for the material placement frame 6. A gear 22 is fixedly installed at the end of each support arm 20 away from the pulley 10, and the gears 22 on adjacent support arms 20 mesh with each other. Two symmetrically distributed fixing plates 23 are fixedly installed between the two guide plates 18, and the fixing plates 23 are fixedly installed between the two support plates 2. A support frame 24 is fixedly installed on each corresponding side of the two guide plates 18. Both ends are arc-shaped structures. The outer side of the support frame 24 contacts the outer side of the material placement frame 6. When the material placement frame 6 moves, it can move along the outer side of the two support frames 24, so that the material placement frame 6 can horizontally convey aluminum foil. When the pulley 10 moves to the side of the guide plate 18, the pulley 10 moves along the arc surface of the guide plate 18. The elasticity of the coil spring 21 causes the support arm 20 to drive the pulley 10 to abut against the arc surface of the guide plate 18. At the same time, the support arm 20 can drive the gear 22 at the end of the other support arm 20 to rotate through the gear 22 at its end, so that the two support arms 20 swing in a spreading motion state, and drive the corresponding pulley 10 to abut against the guide plate. On the outside of guide plate 18, to prevent the material placement frame 6 from colliding with the support frame 24, thereby improving the stability of the material placement frame 6 conveying. Two symmetrically distributed guide frames 35 are fixedly installed on the outside of guide plate 18, and the corresponding side of the two guide frames 35 is in contact with the outside of pulley 10, so that guide frames 35 provide support and positioning for the outside of pulley 10, preventing pulley 10 from detaching from guide plate 18 and improving the stability of pulley 10 movement. A support cylinder 36 is sleeved on the outside of drive rod 11, and the support cylinder 36 is fixedly installed between the two guide plates 18, so that support cylinder 36 provides auxiliary support for drive rod 11 and can also improve the firmness of the installation of the two guide plates 18.

[0023] Example 3: Please refer to Figures 3-7This embodiment further illustrates other embodiments. The slag removal mechanism shown in the figure includes a plurality of toothed scrapers 25 equidistantly arranged inside the material frame 6. The toothed scrapers 25 can scrape off impurities on the grid 7. The slag removal mechanism also includes a sliding cavity opened inside the material frame 6. A sliding frame 26 is slidably installed inside the sliding cavity. The toothed scrapers 25 are fixedly installed inside the sliding frame 26 and slide to the inside of the sliding cavity. A spiral frame 27 is fixedly installed on one side of the sliding frame 26. One side of the spiral frame 27 slides to the outside of the material frame 6. A groove is opened on the outside of the mounting rod 15 on one side of the material frame 6 for limiting the sliding of the spiral frame 27. The spiral frame 27 is away from the sliding groove. A sliding rod 28 is fixedly installed on one side of the frame 26. A sliding hole for limiting the sliding of the sliding rod 28 is provided on the inner side of the mounting rod 15. A spherical stop block 29 is fixedly installed at the end of the sliding rod 28 away from the retractable frame 27. The spherical stop block 29 is located on the outer side of the mounting rod 15. A tension spring 30 is sleeved on the outer side of the mounting rod 15. The tension spring 30 is fixedly installed between the retractable frame 27 and the inner side of the sliding groove of the mounting rod 15. A mounting plate 31 is provided above the air intake hood 8, and the mounting plate 31 is fixedly installed on the outer side of one of the support plates 2. Multiple spherical grooves evenly distributed on the outer side of the mounting plate 31 are provided for the spherical stop block 29 to be inserted and limited. After the laser cutter 5 finishes cutting the aluminum foil, the conveyor belt 39 passes through... The material placement frame 6 is conveyed via the mounting rod 15, causing the mounting rod 15 to align the spherical abutment 29 on the sliding rod 28 with the first spherical groove on the mounting plate 31. The spring force of the tension spring 30 pulls the retractable frame 27, causing it to move synchronously with the sliding rod 28 and the sliding frame 26. The sliding rod 28 causes the spherical abutment 29 to insert into the spherical groove, and the sliding frame 26 causes the toothed scraper 25 to move along the inner side of the grid 7. As the material placement frame 6 moves, the spherical abutment 29 can be removed from the first spherical groove on the mounting plate 31, and the retractable frame 27 can move back to its original position, resetting the toothed scraper 25. When aligned with the second spherical groove, the spherical abutment 29 re-inserts into the second spherical groove. Within the groove, the toothed scraper 25 reciprocates to remove impurities remaining on the inner side of the grille 7, facilitating the cleaning of residual impurities by the intake hood 8 before the first contact plate 16 separates from the second contact plate 17. Two symmetrically distributed support rods 37 are slidably installed on both sides of the slide frame 26, and the support rods 37 are fixedly installed on the inner side of the slide cavity, allowing the slide frame 26 to move along the outer side of the four support rods 37, preventing the slide frame 26 from tilting. Multiple ball bearings 38 are rotatably installed at the bottom of the slide frame 26, and the ball bearings 38 contact the bottom of the slide cavity, allowing the slide frame 26 to drive the ball bearings 38 to move along the inner side of the slide cavity, preventing the slide frame 26 from wearing out due to long-term movement within the slide cavity.

[0024] Working principle: First, the operator places aluminum foil in the placement frame 6 located on the left side of the device base 1, so that the aluminum foil is laid flat on the grid 7 of the placement frame 6. Then, the two drive rods 11 are activated. The drive rods 11 drive the two conveyor belts 39 to rotate synchronously through the two transmission wheels 12. The conveyor belts 39 drive the mounting belts 13 to move synchronously, so that the mounting belts 13 drive the mounting rods 15 to move. The mounting rods 15 drive the placement frame 6 to move horizontally above the two support frames 24 through the U-shaped frame 14, and drive the support arm 20 to move along the pulley 10 along the outside of the guide plate 18 through the positioning rod 19. So that the placement frame 6 moves to the left through the grid 7, and places the next aluminum foil on the grid 7 of the next placement frame 6. When the placement frame 6 containing aluminum foil moves to the top of the laser cutter 5. At this time, the first contact plate 16 at the bottom of the material frame 6 contacts the second contact plate 17 at the top of the air inlet hood 8. The second contact plate 17 pushes the pressure frame 33 at the bottom of the first contact plate 16, and retracts the pressure frame 33 into the U-shaped groove of the first contact plate 16, so that the pressure frame 33 compresses the spring 34. Using the elasticity of the spring 34, the pressure frame 33 presses against the top of the first contact plate 16. When the first contact plate 16 and the second contact plate 17 are aligned, the pressure frame 33 can seal the first contact plate 16 and the second contact plate 17. Then, with the cooperation of the transverse slide 3 and the longitudinal slide 4, the laser cutter 5 cuts the aluminum foil. At the same time, the dust collection box 9 adsorbs the aluminum foil on the top of the grid 7 through the hose and the air inlet hood 8, and sucks away the debris and impurities generated by the laser cutter 5 when cutting the aluminum foil.After the laser cutter 5 finishes cutting the aluminum foil, the conveyor belt 39 moves the material placement frame 6 to the right via the mounting rod 15. The mounting rod 15 moves the spherical abutment 29 via the slide rod 28, aligning the spherical abutment 29 with the first spherical groove on the mounting plate 31. The spring force of the tension spring 30 pulls the retracting frame 27, causing the retracting frame 27 to move synchronously with the slide rod 28 and the slide frame 26. The slide rod 28 pushes the spherical abutment 29 into the spherical groove. Meanwhile, the slide frame 26 moves the toothed scraper 25 along the inner side of the grid 7. As the material placement frame 6 moves, the spherical abutment 29 moves out of the first spherical groove on the mounting plate 31. The reaction force of the mounting plate 31 on the spherical abutment 29 pushes the slide rod 28 back to its original position, causing the slide rod 28 to push the toothed scraper 25 along the inner side of the grid 7 via the retracting frame 27. The scraper 25 is reset, and when the spherical abutment 29 is aligned with the second spherical groove, the spherical abutment 29 is inserted into the second spherical groove. As the first contact plate 16 moves along the top of the second contact plate 17, the toothed scraper 25 reciprocates inside the grille 7 to clean the impurities remaining inside the grille 7. Before the air intake hood 8 separates from the first contact plate 16 and the second contact plate 17, the air intake hood 8 sucks the remaining impurities into the dust collection box 9. Finally, the conveyor belt 39 conveys the processed aluminum foil out and moves the next aluminum foil to be processed to below the laser cutter 5, thereby achieving the effect of continuous aluminum foil processing, realizing one-to-one cleaning of the grille 7, preventing adsorption and pulling on other aluminum foils, and ensuring the flatness of the aluminum foil during processing.
