Description

Technical Field

[0002] Aluminum foil welding equipment is mainly used to connect aluminum foil through different welding technologies (such as ultrasonic welding, laser welding, etc.). It is widely used in food packaging, electronic product packaging, medical packaging and other fields. In some industrial scenarios, aluminum foil rolled into a tube can be used as insulation material to prevent heat leakage.

[0003] However, the existing aluminum foil welding equipment has the following problems when welding cylindrical aluminum foil: Problem 1: In some industrial scenarios, different requirements necessitate different diameters of aluminum foil. Existing aluminum foil welding equipment typically uses a cylinder to support the hollow center of the foil, then welds both ends to form a hollow cylinder. However, when welding foils of varying diameters, the cylinder cannot be adjusted to meet varying requirements, resulting in limited adaptability. Based on question one, question two is raised: when the aluminum foil is rolled to different degrees, cylindrical aluminum foils of different thicknesses will be formed. Different degrees of rolling will cause the two ends of the aluminum foil to move to different positions of the cylinder. Therefore, when the aluminum foil is rolled to different degrees, it should also be rotated and adjusted to make the two ends of the aluminum foil easily docked with the welding head. In response to the above problems, the inventors proposed an intelligent automatic aluminum foil welding device and welding method to solve the above problems. Summary of the Invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Example like Figures 1-12 As shown, the present invention provides an intelligent automatic aluminum foil welding device, comprising a frame 1, on which a rotating assembly 7 for rotating an aluminum foil roll is mounted, and the rotating assembly 7 is arranged along the axis direction of the frame 1; The rotating assembly 7 is equipped with a reducing assembly 3 for supporting aluminum foil paper tubes of different diameters. The rotating assembly 7 drives the reducing assembly 3 to rotate. The reducing assembly 3 is provided with a clamping end assembly 4, which is used to clamp one end of the aluminum foil paper tube; The two sides of the frame 1 are respectively installed with limit components 2, which are used to provide limit support for the outer side of the aluminum foil paper tube; When the diameter-changing component 3 rotates, it drives one end of the aluminum foil to rotate, and the aluminum foil is wound circumferentially on the outside of the diameter-changing component 3. The limiting component 2 adaptively limits the formed aluminum foil tube; An inner layer end welding assembly 5 is slidably connected to the outer wall of the clamping end assembly 4, and is used to weld the inner end of the aluminum foil paper tube; An outer layer welding assembly 10 is installed on the outer wall of the limiting assembly 2 for welding the outer end of the aluminum foil paper tube.

[0033] The rotating assembly 7 includes a first motor 701, which is mounted on the outer wall of the frame 1. A rotating shaft 702 is mounted on the output shaft of the first motor 701. A support plate 703 is fixedly connected to the outer wall of the rotating shaft 702. The reducing assembly 3 is mounted on the support plate 703. When the first motor 701 is started, its output shaft drives the rotating shaft 702 to rotate. Since the reducing assembly 3 is mounted on the support plate 703 of the rotating shaft 702, the rotation of the rotating shaft 702 will drive the reducing assembly 3 to rotate.

[0034] The reducing assembly 3 includes a second motor 301, which is mounted on the outer wall of the support plate 703. A driving gear 302 is mounted on the output shaft of the second motor 301. A driven gear 303 is rotatably connected to the outer wall of the rotating shaft 702. The driving gear 302 and the driven gear 303 are meshed with each other. An arc guide groove 304 is provided on the outer wall of the driven gear 303. A connecting rod 305 is slidably connected to the support plate 703. One end of the connecting rod 305 is slidably connected to the arc guide groove 304. On the inner wall, the other end of the connecting rod 305 is fixedly connected to the connecting rod 305, and the clamping end assembly 4 is installed on the outer wall of one of the connecting rods 305. The second motor 301 in the diameter-changing assembly 3 is started, and the driving gear 302 on its output shaft drives the driven gear 303 to rotate. When the driven gear 303 rotates, the arc-shaped guide groove 304 cooperates with the connecting rod 305 to drive the arc plate 306 to move. During the movement of the arc plate 306, the cylindrical diameter formed by the aluminum foil paper 11 is adjusted.

[0035] The clamping end assembly 4 includes a U-shaped plate 401, which is fixedly connected to the outer wall of the arc-shaped plate 306. Several first springs 402 are fixedly connected to the inner wall of the U-shaped plate 401. A movable plate 404 is connected to the first spring 402. The movable plate 404 is slidably connected to the inner wall of the U-shaped plate 401. A fork plate 403 is fixedly connected to the outer wall of the arc-shaped plate 306. Since the U-shaped plate 401 in the clamping end assembly 4 is fixedly connected to the arc-shaped plate 306, and the movable plate 404 is connected to the first spring 402 in the U-shaped plate 401, the bent end 1101 of the aluminum foil paper 11 is clamped.

[0036] An aluminum foil 11 is sleeved on the outer wall of the arc-shaped plate 306. The aluminum foil 11 is provided with a bent end 1101. The bent end 1101 is clamped between the movable plate 404 and the U-shaped plate 401. The fork plate 403 lifts up the aluminum foil 11, and a gap is left between the bent end 1101 and the fork plate 403, which is used to cooperate with the right-angled triangle plate 12 on the outer wall of the carrier 502 to first pass through the gap between the bent end 1101 and the fork plate 403, and push the bent end 1101 out from the clamping end assembly 4.

[0037] The inner end welding assembly 5 includes a guide rail 501, which is fixedly connected to the outer wall of the U-shaped plate 401 and extends to the outside of the diameter reducing assembly 3. A carrier 502 is slidably connected to the guide rail 501, and a sliding rod is slidably connected to the bottom of the carrier 502. A first hot welding plate 504 is installed on the top of the sliding rod. A second spring 503 is provided between the first hot welding plate 504 and the carrier 502, and the second spring 503 is located on the outside of the sliding rod. A sliding plate 505 is slidably connected to the top of the carrier 502, and two rollers 506 are rotatably connected to the sliding plate 505. A screw 507 is rotatably connected to the carrier 502, and the screw 507 passes through the sliding plate 505 and is threadedly connected; A right-angled triangle plate 12 is fixedly connected to the outer wall of the carrier 502. The right-angled triangle plate 12 is used to pass through the gap between the bent end 1101 and the fork plate 403, and is used to push the bent end 1101 out of the clamping end assembly 4, facilitating the inner layer end welding assembly 5 to weld the bent end 1101. After the aluminum foil 11 is adjusted, the carrier 502 slides along the guide rail 501. The position of the sliding plate 505 is adjusted by rotating the screw 507, thereby adjusting the position of the roller 506, so that the aluminum foil 11 can pass between the roller 506 and the first heat welding plate 504. Under the action of the second spring 503, the first heat welding plate 504 can fit and weld the bent end 1101.

[0038] The interior of the rotating shaft 702 is set as a hollow structure. An exhaust hole 7020 is opened at the end of the rotating shaft 702 close to the first motor 701, and two one-way valves 8 are installed at the end of the rotating shaft 702 away from the first motor 701; One of the one-way valves 8 is used to control air intake and serves as an air intake valve; Another one-way valve 8 is used to control exhaust and serves as an exhaust valve. The exhaust valve is connected to an exhaust pipe 6. An air outlet 601 is provided on the outer wall of the exhaust pipe 6. The air outlet 601 faces the bent end 1101. The push rod 13 is supported by the support frame 9. The piston 1301 at one end slides in the rotating shaft 702 toward the first motor 701, and the air inside the rotating shaft 702 is first discharged through the exhaust hole 7020. During the sliding process, due to the negative pressure, the intake valve opens to intake air. When the push rod 13 drives the piston 1301 to move toward the exhaust valve, the gas is discharged through the exhaust valve to cool the inner end of the welded aluminum foil 11.

[0039] A push rod 13 is connected to the bottom outer wall of the carrier 502. The push rod 13 passes through the rotating shaft 702 and is slidably connected. One end of the push rod 13 is fixedly connected to a piston 1301. The piston 1301 is slidably connected to the inner wall of the rotating shaft 702. The sliding of the piston 1301 is used to promote air intake or exhaust. The bottom of the frame 1 is slidably connected to a support frame 9 , one end of the support frame 9 is rotatably connected to one end of the push rod 13 , and the support frame 9 is used to support the push rod 13 and the inner end welding assembly 5 .

[0040] The limiting assembly 2 includes an electric telescopic rod 201, the bottom end of which is fixedly connected to the outer wall of the frame 1. A mounting frame 202 is installed on the output end of the electric telescopic rod 201, and an arc-shaped plate frame 203 is installed on the mounting frame 202. The arc-shaped plate frame 203 fits the outer wall of the aluminum foil paper tube for support. A friction wheel 204 is rotatably connected to the arc-shaped plate frame 203 to adaptively limit the aluminum foil paper 11. The outer layer welding assembly 10 includes a groove plate 1001, which is fixedly connected to the outer wall of the friction wheel 204. A slider 1002 is slidably connected to the groove plate 1001, and a slide rod is slidably connected to the slide rod 1002. A second hot welding plate 1004 is installed at one end of the slide rod, and a terminal is provided at the other end of the slide rod. A circular plate 1005 is fixedly connected to the outer wall of the slide rod, and a third spring 1003 is provided between the circular plate 1005 and the groove plate 1001. The outer end of the aluminum foil paper tube is welded, and the outer end welding position can be rotated and adjusted by the rotating assembly 7.

[0041] A welding method for aluminum foil welding equipment, comprising the following steps: Step 1: Roll up the aluminum foil 11 and put it on the outside of the diameter-changing component 3; Step 2: Adjust the diameter of the aluminum foil 11 through the diameter-changing component 3; Step 3: The clamping end assembly 4 clamps and limits one end of the aluminum foil 11, and cooperates with the limiting assembly 2 to limit the aluminum foil 11 to prevent it from turning outward; Step 4: The right-angled triangle plate 12 pushes out the bent end 1101, and the inner end welding assembly 5 welds the inner end of the aluminum foil 11; Step 5: The push rod 13 drives the piston 1301 to push the gas to cool the inner end of the aluminum foil 11; Step six: the outer layer welding assembly 10 welds the outer end of the aluminum foil 11 .

[0042] Working principle: First, the aluminum foil 11 is placed on the curved plate 306 to form an aluminum foil tube. The bent end 1101 is clamped between the movable plate 404 and the U-shaped plate 401. The fork plate 403 lifts the aluminum foil 11, and a gap is left between the bent end 1101 and the fork plate 403. When the second motor 301 in the reducer assembly 3 is not working, the curved plate 306 provides preliminary fixed support for the aluminum foil tube. When the first motor 701 is started, its output shaft drives the rotating shaft 702 to rotate. Since the diameter-reducing component 3 is installed on the support plate 703 of the rotating shaft 702, the rotation of the rotating shaft 702 drives the diameter-reducing component 3 to rotate. At the same time, the second motor 301 in the diameter-reducing component 3 is started, and the driving gear 302 on its output shaft drives the driven gear 303 to rotate. When the driven gear 303 rotates, the arc-shaped guide groove 304 cooperates with the connecting rod 305 to drive the arc plate 306 to move. During the movement of the arc plate 306, the diameter of the cylinder formed by the aluminum foil 11 is adjusted, which can be either enlarged or reduced. When the aluminum foil paper tube is sleeved on the diameter-reducing component 3 or adjusted, the diameter of the aluminum foil paper tube must be greater than or equal to the diameter of the diameter-reducing component 3, so that it can be completely sleeved on the periphery of the diameter-reducing component 3, thereby ensuring that the two ends of the aluminum foil paper tube can be welded; Since the U-shaped plate 401 in the clamping end assembly 4 is fixedly connected to the arc-shaped plate 306, and the U-shaped plate 401 is connected to the movable plate 404 via the first spring 402 to clamp the bent end 1101 of the aluminum foil 11, when the diameter-reducing assembly 3 rotates, it drives one end of the aluminum foil 11 to rotate, and the aluminum foil 11 is circumferentially wound around the outer side of the diameter-reducing assembly 3, so that after the cylindrical diameter of the aluminum foil 11 is adjusted, it is rewound; The electric telescopic rod 201 in the limiting component 2 adjusts the height of the mounting frame 202 according to the size of the aluminum foil roll, so that the arc-shaped plate frame 203 fits the outer wall of the aluminum foil 11 for support, and the friction wheel 204 on the arc-shaped plate frame 203 can play an auxiliary supporting and limiting role during the rotation of the aluminum foil 11, adaptively limiting the formed aluminum foil 11 to prevent the aluminum foil 11 from turning outward during the winding process; After the adjustment of the aluminum foil 11 is completed, when the inner end of the aluminum foil 11 needs to be welded, the carrier 502 slides along the guide rail 501 . The position of the sliding plate 505 is adjusted by rotating the screw 507, and then the position of the roller 506 is adjusted, so that the aluminum foil 11 can pass between the roller 506 and the first heat welding plate 504, so that the aluminum foil 11 remains in contact. The right-angled triangle plate 12 on the outer wall of the carrier 502 first passes through the gap between the bent end 1101 and the fork plate 403, and pushes the bent end 1101 out of the clamping end assembly 4. The right-angled triangle plate 12 provides a certain oblique support for the pushed-out bent end 1101. Subsequently, after the bent end 1101 is pushed out, one end of the first heat welding plate 504 supports the bottom of the bent end 1101, so that the bent end 1101 and the aluminum foil 11 are in contact. At this time, the first heat welding plate 504 can weld the joint of the bent end 1101 and the aluminum foil 11 under the action of the second spring 503; Furthermore, supported by the support frame 9, the piston 1301 at one end of the push rod 13 slides within the rotating shaft 702 toward the first motor 701, first exhausting the air inside the rotating shaft 702 through the exhaust hole 7020. During the sliding process, due to the negative pressure, the intake valve opens to allow air in. When the push rod 13 drives the piston 1301 toward the exhaust valve, the air is exhausted through the exhaust valve, cooling the inner end of the aluminum foil 11 after welding. By controlling the speed of the piston 1301 movement, the exhaust rate is controlled. Aluminum easily oxidizes with oxygen in the air at high temperatures, forming an aluminum oxide film, which affects the quality and appearance of the weld. By controlling the cooling rate during the cooling process, oxidation and discoloration of the aluminum foil 11 surface can be reduced. The support frame 9 supports the push rod 13 and the inner end welding assembly 5. The support frame 9 is rotatably connected to the push rod 13. The support frame 9 is L-shaped. When the inner end welding assembly 5 rotates along with the reducing assembly 3, the support frame 9 facilitates its passage. When the outer end of the aluminum foil tube needs to be welded, during the rotation of the aluminum foil tube, the slider 1002 slides on the groove plate 1001, and the second hot welding plate 1004 is slid and adjusted to weld the outer end of the aluminum foil tube. The second hot welding plate 1004 at one end of the slide rod welds the outer end of the aluminum foil tube under the action of the third spring 1003 and the circular plate 1005.
