Description

Technical Field

[0001] This invention relates to the field of metal foil etching technology, specifically to a metal foil etching apparatus and its usage method. Background Technology

[0002] Metal foil etching equipment is a device used to remove unwanted parts of the surface of metal foil. It is mainly achieved through chemical reactions or physical impact. Metal etching is a technology that removes parts of material through chemical reactions or physical impact. It is widely used in many industries and fields and has become an indispensable part of modern industry. Metal etching technology can be divided into two main categories: wet etching and dry etching. Wet etching uses chemical solutions to corrode the metal surface, while dry etching uses physical or chemical methods to bombard or corrode the metal surface.

[0003] Regarding the aforementioned technologies, it is believed that metal foil is generally collected in rolls. When it is necessary to etch various patterns and logos on its surface, it is gradually extended and flattened outwards. Its surface is then processed by a metal etching machine. However, before processing, the surface of the metal foil needs to be cleaned and dried, and then its surface is flattened before being processed by a metal etching machine. Summary of the Invention

The same servo motor is hinged to the movable end of each of the electric telescopic components 2. A laser etching head is installed on the bottom wall of the servo motor, and the laser etching head is connected to an external laser etching machine.

[0013] Furthermore, a first transmission roller is installed on the left side of the top wall of the workbench, located on both sides of the inner wall of the U-shaped frame; a guide roller is rotatably installed on the inner wall of the cleaning tank; a second transmission roller is installed on the left side of the top wall of the workbench, located on both sides of the U-shaped support; a discharge roller is installed on the right side of the top wall of the workbench; a feeding roller is installed on the left side of the workbench; a receiving roller is installed on the right side of the workbench; a working motor is installed on the rear wall of the receiving roller; and a PLC controller is installed on the front wall of the workbench.

[0014] A method for etching metal foil includes the following steps: S1. Before starting work, first connect the external power supply and PLC controller electrically. The lifting push rod, vacuum cleaner, servo motor, drive motor, electric telescopic component one, drive component, electric telescopic component two, laser etching head and external etching machine are all connected. When starting work, first install the feeding roller on the left side of the worktable, and then extend the metal foil around the winding outward and pass through the outer wall of the transmission roller one, receiving roller and cleaning soft brush in sequence. Then, it enters the cleaning tank, passes through the bottom wall of the guide roller and sticks to the outer wall of the transmission roller two and the discharge roller and is fixed to the outer wall of the receiving roller, thus completing the feeding and installation of the metal foil. S2. By gradually adding cleaning liquid or water into the cleaning tank, the receiving roller is driven by the working motor on the receiving roller to start rotating slowly. Then, the servo motor is started to drive the rotating rod and the cleaning soft brush to rotate. When the cleaning soft brush rotates, it cleans the surface of the metal foil that it contacts, so that the metal foil that has passed the surface of the receiving roller is cleaned. The impurities that are brushed off move backward with the rotation of the cleaning soft brush. When the rotating rod rotates, it will drive the large synchronous wheel to rotate synchronously. S3. Simultaneously start the lifting push rod to push the lifting seat downward in the U-shaped frame. The lifting seat simultaneously drives the slider to move downward along the outer wall of the positioning rod in the inner wall of the limiting groove. Then, the integrated tube and the dust suction hood move downward in sync to approach the metal foil surface. The integrated tube simultaneously drives the dust suction pipe downward. Start the vacuum cleaner. The vacuum cleaner, integrated tube and dust suction hood remove the impurities brushed off by the cleaning soft brush. After passing through the integrated tube and dust suction pipe, the impurities are transported into the collection box through the dust exhaust pipe and stored. S4. After the metal foil passes through the roller brush, it enters the cleaning tank and is cleaned again. It is then moved to the bottom of the drying fan blade by the transmission roller two. When the rotating rod rotates, it drives the large synchronous wheel and the small synchronous wheel to work. When the small synchronous wheel rotates, it drives the transmission shaft and the first bevel gear to rotate. When the first bevel gear rotates, it drives the second bevel gear that meshes with it to rotate synchronously. When the second bevel gear rotates, it drives the connecting shaft and the drying fan blade to rotate at the bottom of the U-shaped bracket, thus drying the metal foil after it has been cleaned in the cleaning tank. S5. When the dried metal foil reaches the bottom of the etching assembly, it stops moving. The drive motor drives the adjusting screw to rotate in the inner wall of the mounting slot. When the adjusting screw rotates, it drives the slide to move the moving plate back and forth along the outer wall of the adjusting screw. At the same time, according to the etching scheme pre-input into the PLC controller, the drive unit drives the rotation of the first electric telescopic component and the second electric telescopic component. The extension and retraction of the movable ends of the first and second electric telescopic components can drive the movement of the second hinge seat and the servo motor. Thus, the laser etching head etches the metal foil under the force. The specific adjustment scheme of the etching assembly is determined according to the etching content and there are no specific adjustment restrictions. After the etching is completed, the etched metal foil is collected by the receiving roller.

[0015] The present invention has the following beneficial effects: (1) The metal foil etching apparatus and its usage method, through the cooperation of the cleaning component, the dust collection component and the cleaning tank, thoroughly cleans the surface of the metal foil before processing. First, the surface of the metal foil is cleaned by a roller brush. The impurities brushed off are removed by a vacuum cleaner to prevent them from accumulating on the surface of the metal foil. The metal foil after the roller brush is then transported into the cleaning tank for cleaning. This ensures that the surface of the metal foil is clean and free of any residual impurities after etching, preventing any impact on the etching effect and further improving the etching quality of the metal foil.

[0016] (2) The metal foil etching device and its usage method, through the setting of the air drying component, mainly the cleaning component works in conjunction with the synchronous operation. When the cleaning component is working, it will drive the air drying component to rotate synchronously. The rotation speed of the air drying fan blade is three times the rotation speed of the cleaning soft brush. When the cleaned metal foil moves under the cleaning soft brush, the residual moisture on its surface can be fully dried by the continuous rotation of the air drying fan blade, which is convenient for subsequent etching work.

[0017] (3) The metal foil etching device and its usage method, through the setting of the etching components, when the cleaned metal foil moves under the laser etching head, according to the etching scheme, the etching components are controlled by the PLC controller to work. By adjusting the position of the laser etching head in multiple directions, it can meet the diversified processing needs and improve the functionality and working range of the entire device.

[0018] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0031] Specifically, a transmission roller 10 is installed on the left side of the top wall of the workbench 1 and on both sides of the inner wall of the U-shaped frame 5; a guide roller 14 is rotatably installed on the inner wall of the cleaning tank 13; a transmission roller 2 11 is installed on the left side of the top wall of the workbench 1 and on both sides of the U-shaped bracket 81; a discharge roller 12 is installed on the right side of the top wall of the workbench 1; a feeding roller 3 is installed on the left side of the workbench 1; a receiving roller 4 is installed on the right side of the workbench 1; a working motor is installed on the rear wall of the receiving roller 4; and a PLC controller 2 is installed on the front wall of the workbench 1. In this embodiment, when etching the metal foil, the metal foil is assisted in conveying by the transmission roller 10, guide roller 14, transmission roller 2 11, and discharge roller 12. At the same time, the metal foil is extended outward by the feeding roller 3, and the working motor drives the take-up roller 4 to rotate and rewind the etched metal foil.

[0032] A method for etching metal foil includes the following steps: S1. Before starting work, first connect the external power supply and PLC controller 2 electrically. The lifting push rod 61, vacuum cleaner 68, servo motor 76, drive motor 95, electric telescopic component 1 98, drive component 910, electric telescopic component 2 911, laser etching head 913 and external etching machine are connected. When starting work, first install the feeding roller 3 on the left side of the worktable 1. Then extend the metal foil that is wrapped around the worktable outward and pass through the outer wall of the transmission roller 10, receiving roller 72 and cleaning soft brush 73 in sequence. Then enter the cleaning tank 13, pass through the bottom wall of the guide roller 14 and stick to the outer wall of the transmission roller 2 11 and the discharge roller 12 and fix it to the outer wall of the receiving roller 4 to complete the feeding and installation of the metal foil. S2. By gradually adding cleaning liquid or water into the cleaning tank 13, the receiving roller 4 is driven by the working motor on the receiving roller 4 to start rotating slowly. Then, the servo motor 76 is started to drive the rotating rod 71 and the cleaning soft brush 73 to rotate. When the cleaning soft brush 73 rotates, it cleans the surface of the metal foil that it contacts, so that the metal foil that has passed the surface of the receiving roller 72 is cleaned by the roller. The impurities that are brushed off move backward with the rotation of the cleaning soft brush 73. When the rotating rod 71 rotates, it will drive the large synchronous wheels 74 and 75 to rotate synchronously. S3. Simultaneously start the lifting push rod 61 to push the lifting seat 65 to move downward in the U-shaped frame 5. Simultaneously, the lifting seat 65 drives the slider 64 to move downward along the outer wall of the positioning rod 63 in the inner wall of the limiting groove 62. Then, the integrated tube 67 and the dust suction hood 66 move downward in sync to approach the metal foil surface. Simultaneously, the integrated tube 67 drives the dust suction pipe 69 downward, start the vacuum cleaner 68, and remove the impurities brushed off by the cleaning soft brush 73 through the vacuum cleaner 68, integrated tube 67 and dust suction hood 66. After passing through the integrated tube 67 and dust suction pipe 69, the impurities are transported into the collection box 611 through the dust discharge pipe 610 and collected and stored. S4. After the metal foil passes through the roller brush, it enters the cleaning tank 13 and is cleaned again. It is then moved to the bottom of the drying fan blade 86 by the transmission roller 11. When the rotating rod 71 rotates, it drives the large synchronous wheel 74 and 75 and the small synchronous wheel 87 to perform transmission work. When the small synchronous wheel 87 rotates, it drives the transmission shaft 82 and the bevel gear 83 to rotate. When the bevel gear 83 rotates, it drives the bevel gear 84 meshing with it to rotate synchronously. When the bevel gear 84 rotates, it drives the connecting shaft 85 and the drying fan blade 86 to rotate at the bottom of the U-shaped bracket 81, thus drying the metal foil after it has been cleaned in the cleaning tank 13. S5. When the dried metal foil reaches the bottom of the etching assembly 9, it stops moving. The drive motor 95 drives the adjusting screw 93 to rotate in the inner wall of the mounting groove 92. When the adjusting screw 93 rotates, it drives the slide 94 to move the moving plate 96 back and forth along the outer wall of the adjusting screw 93. At the same time, according to the etching scheme pre-input into the PLC controller 2, the drive component 910 drives the rotation of the electric telescopic component 1 98 and the electric telescopic component 2 911. The extension and retraction of the movable ends of the electric telescopic component 1 98 and the electric telescopic component 2 911 can drive the hinge seat 2 99 and the servo motor 912 to move. Then, the laser etching head 913 is subjected to force to etch the metal foil. The specific adjustment scheme of the etching assembly 9 is determined according to the etching content and there is no specific adjustment limit. After the etching is completed, the etched metal foil is collected by the receiving roller 4.

[0033] The working principle of this device is as follows: Before operation, it is first electrically connected to the external power supply and PLC controller 2. The lifting push rod 61, vacuum cleaner 68, servo motor 76, drive motor 95, electric telescopic component 1 98, drive component 910, electric telescopic component 2 911, laser etching head 913, and external etching machine are connected. When the operation starts, the feeding roller 3 is first installed on the left side of the worktable 1. The metal foil that is wound around the worktable is extended outward and passes through the outer wall of the transmission roller 10, receiving roller 72, and cleaning soft brush 73 in sequence. Then it enters the cleaning tank 13, passes through the bottom wall of the guide roller 14, and is attached to the outer wall of the transmission roller 2 11 and the discharge roller 12 and fixed to the outer wall of the receiving roller 4, thus completing the feeding and installation of the metal foil. By gradually adding cleaning liquid or water into the cleaning tank 13, the receiving roller 4 is driven by the working motor on the receiving roller 4 to start rotating slowly. Then, the servo motor 76 is started to drive the rotating rod 71 and the cleaning soft brush 73 to rotate. When the cleaning soft brush 73 rotates, it cleans the surface of the metal foil that it contacts, so that the metal foil that has passed the surface of the receiving roller 72 is cleaned by the roller. The impurities that are brushed off move backward with the rotation of the cleaning soft brush 73. When the rotating rod 71 rotates, it will drive the large synchronous wheels 74 and 75 to rotate synchronously. The lifting push rod 61 is activated simultaneously to push the lifting seat 65 downward within the U-shaped frame 5. The lifting seat 65 simultaneously drives the slider 64 to move downward along the outer wall of the positioning rod 63 within the inner wall of the limiting groove 62. Consequently, the integrated tube 67 and the dust suction hood 66 move downward synchronously to approach the metal foil surface. The integrated tube 67 simultaneously drives the dust suction pipe 69 downward, activating the vacuum cleaner 68. The vacuum cleaner 68, integrated tube 67, and dust suction hood 66 remove the impurities brushed down by the cleaning soft brush 73. After passing through the integrated tube 67 and dust suction pipe 69, the impurities are transported through the dust discharge pipe 610 and enter the collection box 611 for collection and storage. After the metal foil passes through the roller brush, it enters the cleaning tank 13 and is cleaned again. It is then moved to the bottom of the drying fan blade 86 by the transmission roller 11. When the rotating rod 71 rotates, it drives the large synchronous wheel 74 and 75 and the small synchronous wheel 87 to perform transmission. When the small synchronous wheel 87 rotates, it drives the transmission shaft 82 and the bevel gear 83 to rotate. When the bevel gear 83 rotates, it drives the bevel gear 84 meshing with it to rotate synchronously. When the bevel gear 84 rotates, it drives the connecting shaft 85 and the drying fan blade 86 to rotate at the bottom of the U-shaped bracket 81, thus drying the metal foil after it has been cleaned in the cleaning tank 13. When the dried metal foil reaches the bottom of the etching assembly 9, it stops moving. The drive motor 95 drives the adjusting screw 93 to rotate in the inner wall of the mounting groove 92. When the adjusting screw 93 rotates, it drives the slide 94 to move the moving plate 96 back and forth along the outer wall of the adjusting screw 93. At the same time, according to the etching scheme pre-input into the PLC controller 2, the drive component 910 drives the rotation of the electric telescopic component 1 98 and the electric telescopic component 2 911. The extension and retraction of the movable ends of the electric telescopic component 1 98 and the electric telescopic component 2 911 can drive the hinge seat 2 99 and the servo motor 912 to move. Then, the laser etching head 913 etches the metal foil under the action of force. The specific adjustment scheme of the etching assembly 9 is determined according to the etching content and there is no specific adjustment limit. After the etching is completed, the etched metal foil is collected by the receiving roller 4. After the local metal foil processing is completed, continue to perform the above-mentioned work process of brushing, dust removal, cleaning, drying and etching on the metal foil to prevent the impurities remaining on the metal foil surface from affecting the etching effect.

Before starting work, first connect the external power supply and PLC controller (2) to the lifting push rod (61), vacuum cleaner (68), servo motor (76), drive motor (95), electric telescopic part one (98), drive part (910), electric telescopic part two (911), laser etching head (913) and external etching machine. When starting work, first install the feeding roller (3) on the left side of the workbench (1), and start extending the metal foil around the winding outward and passing through the outer wall of the transmission roller one (10), receiving roller (72) and cleaning soft brush (73) in sequence, and then enter the cleaning tank (13) and pass through the bottom wall of the guide roller (14) to adhere to the outer wall of the transmission roller two (11) and the discharge roller (12) and fix it to the outer wall of the receiving roller (4) to complete the feeding installation of the metal foil. S2. By gradually adding cleaning liquid or water into the cleaning tank (13), the receiving roller (4) is driven to start rotating slowly by the working motor on the receiving roller (4). Then, the servo motor (76) is started to drive the rotating rod (71) and the cleaning soft brush (73) to rotate. When the cleaning soft brush (73) rotates, it cleans the surface of the metal foil that it contacts, so that the metal foil that passes through the receiving roller (72) is cleaned by the roller. The impurities that are brushed off move backward with the rotation of the cleaning soft brush (73). When the rotating rod (71) rotates, it will drive the large synchronous wheel (74) and (75) to rotate synchronously. S3. Simultaneously start the lifting push rod (61) to push the lifting seat (65) to move downward in the U-shaped frame (5). The lifting seat (65) simultaneously drives the slider (64) to move downward along the outer wall of the positioning rod (63) in the inner wall of the limiting groove (62). Then the integrated tube (67) and the dust hood (66) move downward synchronously to approach the metal foil surface. The integrated tube (67) simultaneously drives the dust suction pipe (69) downward. Start the vacuum cleaner (68). The vacuum cleaner (68), integrated tube (67) and dust hood (66) suck up the impurities brushed down by the cleaning soft brush (73). After passing through the integrated tube (67) and dust suction pipe (69), the impurities are transported into the collection box (611) through the dust discharge pipe (610) and collected and stored. S4. After the metal foil after passing through the roller brush enters the cleaning tank (13), it is cleaned again. It is then moved to the bottom of the drying fan blade (86) by the transmission roller two (11). When the rotating rod (71) rotates, it drives the large synchronous wheel (74) and (75) and the small synchronous wheel (87) to work. When the small synchronous wheel (87) rotates, it drives the transmission shaft (82) and the first bevel gear (83) to rotate. When the first bevel gear (83) rotates, it drives the second bevel gear (84) that meshes with it to rotate synchronously. When the second bevel gear (84) rotates, it drives the connecting shaft (85) and the drying fan blade (86) to rotate at the bottom of the U-shaped bracket (81) to air dry the metal foil after it has been cleaned in the cleaning tank (13). S5. When the dried metal foil reaches the bottom of the etching assembly (9), it stops moving. The adjusting screw (93) is driven to rotate in the inner wall of the mounting slot (92) by the drive motor (95). When the adjusting screw (93) rotates, it will drive the slide (94) to move the moving plate (96) back and forth along the outer wall of the adjusting screw (93). At the same time, according to the etching scheme pre-input into the PLC controller (2), the electric telescopic component (98) can be driven to rotate by the drive component (910). The drive unit (910) drives the rotation of the electric telescopic component two (911). At the same time, the extension and retraction of the movable ends of the electric telescopic component one (98) and the electric telescopic component two (911) can drive the hinge seat two (99) and the servo motor (912) to move. Then, the laser etching head (913) is subjected to force to etch the metal foil. The specific adjustment scheme of the etching component (9) is determined according to the etching content and no adjustment restrictions are imposed. After the etching is completed, the etched metal foil is collected by the receiving roller (4).
