Description

Technical Field

[0001] This invention relates to the field of automatic feeding and cutting technology, and in particular to a feeding device for aluminum foil roll forming in the production of automotive radiators. Background Technology

[0002] Composite current collector film is the main material for producing aluminum foil for automotive radiators. Composite current collector film mainly adopts a sandwich structure of "metal-polymer material-metal". Composite aluminum current collector deposits aluminum metal on the surface of the base film through a one-time vapor deposition method. Vacuum coating is usually a continuous coating process of the whole roll of product completed in a vacuum chamber, and then the chamber is opened to take out the whole roll of product.

[0003] Because the height of the splashed aluminum dots on the film surface varies during the vapor deposition process, a pressure roller process is needed to press and align them. The second step of the rolling process has a significant drawback. Due to the working characteristics of the rolling press and the product characteristics of the fluid in the laminating machine, there are splashed aluminum dots of different sizes and heights on the surface of the fluid in the laminating machine. When the rolling process is completed, the height of the splashed aluminum dots will be pressed into a uniform shape due to the pressure, and the surface of the composite current collector film will become flat. However, some splashed aluminum dots will "slip through the net" and not be pressed, or because the splashed dots are too large, their height will still be very high after pressing. These splashed aluminum dots that are not pressed will be blocked by the doctor blade during the coating stage in the battery cell industry, which will seriously lead to film breakage and affect the production quality of aluminum foil. To prevent large splashes that haven't been pressed from flowing downstream, a slit scraper device is added after roll forming. This slit device removes large splashes still attached to the film surface after roll forming, preventing them from flowing to downstream processes. The scraper device can adjust the height of the slit using a cylinder and wedge to accommodate different base film thicknesses and coating thicknesses. Each product has a specified slit height. In actual production, this slit scraper does effectively remove large splashes, keeping defective products within the production line and preventing them from flowing to downstream processes. However, due to the excessive number of large splashes on the film surface, the film is often broken by the scraper each time a large splash passes by. After breaking, the film needs to be re-rolled, often resulting in wasted finished film during the scraper removal process.

[0004] Therefore, a new type of aluminum foil roll forming feeding device for automotive radiator production can be used to overcome the shortcomings of existing technologies. Summary of the Invention

[0008] Preferably, the aluminum dot cutting assembly further includes two horizontal plates fixedly mounted on the bracket, and a first guide roller and a second guide roller are rotatably mounted on the two horizontal plates.

[0009] Preferably, the micro-cutting mechanism further includes a disc rotatably mounted on a corresponding horizontal plate, a shaft rotatably mounted on each of the two discs, a spring coil fixedly mounted between each of the two discs and the corresponding shaft, a motor fixedly mounted on one of the horizontal plates, the motor drive end being fixedly connected to the corresponding disc, a rotating frame fixedly mounted on each of the two shafts, and a first transmission roller, a second transmission roller, a first limiting roller, and a second limiting roller rotatably mounted between the two rotating frames. The laser cutting structure has two sets, which respectively perform sputtered aluminum dot cutting on the upper and lower surfaces of the film material, and are both mounted on one of the rotating frames.

[0010] Preferably, the laser cutting structure includes a movable frame fixedly mounted on a rotating frame, a movable plate slidably mounted on the movable frame, a laser emitter fixedly mounted on the movable plate, an adjustment component that cooperates with the movable plate mounted on the movable frame, and a thickness sensing component that cooperates with the film material mounted on the movable plate.

[0011] Preferably, the adjusting component includes a motor fixedly mounted on the movable frame, a take-up roller mounted on the drive end of the motor, a steel wire rope wound on the take-up roller, a steel wire rope fixedly connected to a movable plate at the end of the steel wire rope away from the take-up roller, and a plurality of return springs fixedly mounted between the movable plate and the movable frame. Two rollers that cooperate with the wire rope are rotatably mounted on the movable frame for adjusting the direction of the wire rope.

[0012] Preferably, the thickness sensing component includes a movable block slidably mounted on a movable plate, a sensing roller that abuts against the membrane material is rotatably mounted on the movable block, and a pressure sensor is fixedly mounted between the sensing roller and the movable plate.

[0014] Preferably, a steering roller that cooperates with the tension roller is rotatably mounted on the bracket, and two vision detectors are fixedly mounted between the two rotating plates.

[0015] The present invention also provides a method for feeding aluminum foil roll forming in automotive radiator production, including the above-mentioned feeding device for aluminum foil roll forming in automotive radiator production, and further including the following steps: S1. First, the membrane material on the unwound membrane material is pulled out. The membrane material passes through the dust removal component, the aluminum dot cutting component and the tension control component in sequence, and then passes out from the guide roller. S2. Next, the end of the membrane material that is protruding is put into the roller forming equipment for feeding. During the feeding process, the surface of the membrane material is cleaned by the dust removal component. S3. In addition, during the feeding process, an aluminum spot cutting assembly is used to cut the splashed aluminum spots on the surface of the film material to ensure that the aluminum spots on the film material are even. S4. Finally, the tension of the membrane material is controlled by the tension control component, so that the membrane material is fed into the roller pressing equipment with a certain degree of tension.

[0016] Compared with existing technologies, the advantages of this invention are: 1. When feeding aluminum foil roll forming equipment for automotive radiators, this equipment can remove splattered aluminum spots on the surface of the film material, resulting in higher stability and cutting efficiency. It can effectively prevent the film material from deforming due to scraper cutting and effectively protect the film material.

[0017] 2. When removing splattered aluminum spots from the surface of the aluminum foil in the production of this automotive radiator, the aluminum foil roll forming feeding device uses a dust removal component to clean the dust on the surface of the film material, avoiding the influence of dust on the cutting deviation. The tension of the film material is controlled by a tension control component to ensure that the splattered aluminum spots are fully exposed, making the cutting of the splattered aluminum spots more thorough.

[0018] 3. When removing splattered aluminum spots from the surface of the aluminum foil in the production of this automotive radiator, two laser emitters mounted on the same rotating frame 31 are used to simultaneously cut the splattered aluminum spots on both sides of the film. In addition, a pressure sensor is set up in conjunction with the motor to automatically adjust the slit between the laser emitter and the film according to the thickness of the film. This makes it more applicable and avoids the cutting deviation caused by uneven film.

[0019] 4. When removing splattered aluminum spots from the surface of the film material, the aluminum foil roll forming feeding device for automotive radiator production uses a spring coil, a first guide roller, a second guide roller, a first limit roller, and a second limit roller to straighten the film material that needs to be cut off of the splattered aluminum spots, making the thickness detection of the film material more accurate.

Detailed Implementation

[0022] 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.

[0023] Example 1: Refer to Figures 1-8 A feeding device for rolling aluminum foil in automobile radiator production includes an unwinding film 1, a guide roller 2, a film 3, and a bracket 9. It also includes a first support component 4, a tension control component 5, an aluminum dot cutting component 6, a dust removal component 7, and a second support component 8 installed on the bracket 9. The first support assembly 4 is used to place the guide roller 2; the second support assembly 8 is used to place the unwound film 1; the film 3 passes through the cleaning assembly 7, the aluminum dot cutting assembly 6 and the tension control assembly 5 in sequence.

[0024] The second support assembly 8 is equipped with a driver that works in conjunction with the guide roller 2. This part is based on existing winding technology, and its specific structure and operation will not be described in detail here. It is used to drive the guide roller 2 to rotate for winding. The guide roller 2 is the finished product of the film material 3 after cutting the splashed aluminum points, and the unwound film material 1 is the finished product of the film material 3 before cutting the splashed aluminum points.

[0025] Example 2: This example differs from Example 1 in that: (Refer to...) Figures 11-17 The aluminum dot cutting assembly 6 is used to cut the spattered aluminum dots on the surface of the film material 3. The aluminum dot cutting assembly 6 includes a micro-cutting mechanism 25, which automatically adjusts the slit height according to the thickness of the film material 3. The micro-cutting mechanism 25 includes a laser cutting structure 28, which uses a laser to cut the spattered aluminum dots.

[0026] The aluminum dot cutting assembly 6 also includes two horizontal plates 21 fixedly mounted on the bracket 9, and a first guide roller 23 and a second guide roller 24 are rotatably mounted on the two horizontal plates 21.

[0027] The membrane material 3 passes under the first guide roller 23 and then exits from above the second guide roller 24, forming an inclined membrane material 3 between the first guide roller 23 and the second guide roller 24, forming a certain angle with the horizontal plate 21. The purpose of setting the first guide roller 23 and the second guide roller 24 is to guide the membrane material 3 to the center of gravity of the horizontal plate 21, which facilitates the installation of the micro-cutting mechanism 25, reduces the occupied area, and makes the equipment more compact.

[0028] The micro-cutting mechanism 25 also includes a disc rotatably mounted on a corresponding horizontal plate 21. A shaft is rotatably mounted on each of the two discs. A spring coil 32 is fixedly mounted between each of the two discs and the corresponding shaft. A motor 22 is fixedly mounted on one of the horizontal plates 21. The drive end of the motor 22 is fixedly connected to the corresponding disc. A rotating frame 31 is fixedly mounted on each of the two shafts. A first transmission roller 26, a second transmission roller 27, a first limiting roller 29, and a second limiting roller 30 are rotatably mounted between the two rotating frames 31. There are two sets of laser cutting structures 28, which respectively perform sputtered aluminum dot cutting on the upper and lower surfaces of the film material 3. Both are mounted on one of the rotating frames 31.

[0029] The motor 22 is started, and the drive end of the motor 22 rotates, which drives the disc to rotate. The rotation of the disc drives the shaft to rotate, and the rotation of the shaft drives the rotating frame 31 to rotate. This causes the first transmission roller 26, the second transmission roller 27, the first limit roller 29, and the second limit roller 30 to abut against the upper and lower surfaces of the film material 3, straightening the section of film material 3 that needs to be cut to remove the splattered aluminum spots, ensuring that the cutting area is a straight section, and also ensuring that the film material 3 is perpendicular to the moving direction of the laser emitter 36. The purpose of setting the spring coil 32 between the disc and the shaft is to change the pressure between the first drive roller 26, the second drive roller 27, the first limit roller 29, and the second limit roller 30 and the film material 3. The greater the pressure, the more accurate the straightening. After the first drive roller 26, the second drive roller 27, the first limit roller 29, and the second limit roller 30 come into contact with the film material 3, the drive end of the drive motor 22 continues to rotate. At this time, the spring coil 32 is wound up. The more it is wound up, the greater the elasticity, and the greater the pressure between the first drive roller 26, the second drive roller 27, the first limit roller 29, and the second limit roller 30 and the film material 3 (the pressure needs to be controlled within a certain range).

[0030] The laser cutting structure 28 includes a movable frame 33 fixedly mounted on a rotating frame 31, a movable plate 37 slidably mounted on the movable frame 33, a laser emitter 36 fixedly mounted on the movable plate 37, an adjustment component that cooperates with the movable plate 37 mounted on the movable frame 33, and a thickness sensing component that cooperates with the membrane material 3 mounted on the movable plate 37.

[0031] The adjusting component includes a motor 34 fixedly mounted on the movable frame 33. A take-up roller is mounted on the drive end of the motor 34. A steel wire rope 38 is wound on the take-up roller. The end of the steel wire rope 38 away from the take-up roller is fixedly connected to the movable plate 37. A plurality of return springs 39 are fixedly installed between the movable plate 37 and the movable frame 33.

[0032] Before cutting, the thickness of the membrane material 3 is detected by the aforementioned thickness sensing component. Then, the starting motor 34 drives the take-up roller to rotate and wind up the wire rope 38. (When unwinding, the motor 34 drives in the opposite direction and the movable plate 37 is reset under the action of the return spring 39.) This changes the position of the movable plate 37, and the position of the laser emitter 36 changes with the movement of the movable plate 37, and the slit spacing also changes. Two rollers that cooperate with the wire rope 38 are rotatably mounted on the movable frame 33 to adjust the direction of the wire rope 38. The purpose of this arrangement is to ensure that the wire rope 38 moves smoothly within the movable frame 33 and that the wire rope 38 moves vertically within the movable frame 33.

[0033] The thickness sensing component includes a movable block 40 that is slidably mounted on a movable plate 37. A sensing roller 35 that abuts against the membrane material 3 is rotatably mounted on the movable block 40. A pressure sensor 41 is fixedly mounted between the sensing roller 35 and the movable plate 37. A tension spring is installed between the pressure sensor 41 and the movable plate 37.

[0034] When the sensing roller 35 comes into contact with the membrane material 3, the pressure sensor 41 will sense the pressure. If the thickness of the membrane material 3 suddenly changes, the pressure sensor 41 will send a signal to the motor 34 to change the position of the laser emitter 36. At this time, the tension spring will be compressed or stretched, the pressure value of the pressure sensor 41 will change, and the distance between the laser emitter 36 and the sensing roller 35 will change. When the thickness of membrane material 3 increases, the pressure value of pressure sensor 41 increases; when the thickness of membrane material 3 decreases, the pressure value of pressure sensor 41 decreases.

[0035] Example 3: This example differs from Example 2 in that: (Refer to...) Figures 9-10 The dust removal assembly 7 is used to remove dust from the surface of the membrane material 3. The dust removal assembly 7 includes two support plates 16 fixedly installed on the bracket 9. A fixed dust removal roller 17 is rotatably installed on both support plates 16. A sliding block 20 is slidably installed on each of the two support plates 16. An electric push rod 19 is fixedly installed on each of the two support plates 16. The driving ends of the two electric push rods 19 are fixedly connected to the corresponding sliding blocks 20. A pressure dust removal roller 18 is rotatably installed between the two sliding blocks 20. The membrane material 3 is passed through the fixed cleaning roller 17 and the pressure cleaning roller 18. The sliding block 20 is moved by the electric push rod 19, which in turn moves the pressure cleaning roller 18. The pressure cleaning roller 18 and the fixed cleaning roller 17 will adsorb and remove the dust on the surface of the membrane material 3 by rotating. (Both the pressure cleaning roller 18 and the fixed cleaning roller 16 are existing cleaning technologies, and their specific cleaning methods will not be described here.)

[0036] The tension control assembly 5 is used to control the tension of the membrane material 3. The tension control assembly 5 includes two fixed plates fixedly installed on the bracket 9. A frame 12 is rotatably installed between the two fixed plates. Two rotating plates 13 are rotatably installed on the frame 12. A servo motor is fixedly installed on the frame 12. The drive end of the servo motor is fixedly connected to the rotating plate 13. Two tension rollers 14 are rotatably installed between the two rotating plates 13. A hydraulic rod 11 is rotatably installed on the bracket 9. The telescopic end of the hydraulic rod 11 is rotatably connected to the frame 12.

[0037] Start the hydraulic rod 11 and change the position of the rotating plate 13 according to the winding degree of the guide roller 2 to ensure that the film material 3 is stably discharged (during the winding process, the diameter of the guide roller 2 becomes larger and larger, and the film material 3 becomes more stable everywhere. By changing the position of the rotating plate 13, the winding force is gradually reduced, but the tension of the film material 3 in the cutting area remains unchanged). The servo motor is started to drive the rotating plate 13 to rotate, changing the angle of the rotating plate 13. The larger the angle, the greater the tension of the membrane material 3, and the smaller the angle, the smaller the tension of the membrane material 3.

[0038] A guide roller 10 that cooperates with the tension roller 14 is rotatably mounted on the bracket 9, and two vision detectors 15 are fixedly mounted between the two rotating plates 13; The function of the steering roller 10 is to change the direction of the film material 3, ensuring that the film material 3 remains taut when passing through the two tension rollers 14, and to work with the vision detector 15 to inspect the film material 3 after cutting the aluminum splatter points, ensuring that the cutting meets the standards.

[0039] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
