Description

Technical Field

[0001] The invention belongs to the technical field of welding aluminum edge sealing, and particularly relates to a welding aluminum edge sealing device and a use method thereof. Background Art

[0002] In the field of smart home, all-aluminum home and sheet metal cabinet, edge banding technology is a key link to improve the aesthetics, durability and service life of products. However, the traditional PVC and wood strip edge banding process has many defects, such as easy tearing and breaking in high temperature environment, short value retention time at room temperature, and poor environmental adaptability, which makes it difficult to meet the needs of modern home and industry for high temperature and high humidity environment. In addition, PVC edge banding involves chemical substances in the production process, which has a certain impact on the environment, while wood strip edge banding is easy to be damaged in extreme environments due to the natural properties of wood, and does not have fireproof and anti-corrosion properties. With the rapid development of the all-aluminum home and sheet metal cabinet industries, the market has put forward higher requirements for edge banding technology, and traditional processes can no longer meet their adaptability requirements for high temperature and high humidity environments. The emergence of fiber optic welding technology has brought new solutions to edge banding technology. The fiber optic welding machine melts and connects the materials through a high-energy laser beam. No glue is needed during the welding process, which avoids the problems of weak bonding and overflow caused by glue in traditional processes.

[0059] Abutment hole 10, which is formed at one end of the assembly shell 9;

[0060] The grinding mechanism is arranged on the upper side of the movable plate 16, and is used to grind the weld edge. The grinding mechanism is composed of a suspension rod 21, a grinding head 22, a rotating rod 23, a rack 17 and a gear 18. The suspension rod 21 is fixedly connected to the upper end of the movable plate 16, the rotating rod 23 is rotatably connected to the lower end of the suspension rod 21, the grinding head 22 and the gear 18 are respectively fixedly connected to the two ends of the rotating rod 23, and the rack 17 is fixedly connected to the inner walls of both sides of the assembly shell 9, and the rack 17 is meshed with the gear 18;

[0061] The coiling mechanism is arranged at the upper end of the movable plate 16 and is used for rolling up and conveying the edge banding strips. A base is arranged at the upper end of the movable plate 16 .

[0062] In a specific embodiment of the present invention, when it is necessary to perform aluminum strip edge banding on the sheet, the sheet is placed on the edge banding table 2 of the mounting shell 1. At this time, one end of the sheet will abut against the limiting plate 3, and the vertical plate surface of the limiting plate 3 will be fitted with the welding surface of the sheet. Then, the control mechanism 4 controls the abutting strip 14 to press the sheet downward, and at the same time, the limiting plate 3 is retracted downward through its lifting mechanism, so that the height of the limiting plate 3 is lower than the height of the edge banding table 2. The sheet is limited and fixed by pressing the sheet downward by the abutting strip 14 and the limiting plate 3 is retracted downward. After the sheet is fixed, the edge banding strip 13 is unfolded by the traction roller provided at the upper end of the moving plate 16, so that the unfolded edge banding strip 13 is located between the two coupled pulse welding gun heads 20, and the roller is rolled. The wheel body 25 presses the aluminum strip against the plate to be welded through a spring pre-tightening mechanism to ensure the tightness of the edge banding, and then welds the edge banding strip 13 to one end of the plate through the coupling pulse welding gun head 20 for edge banding, and drives the sliding bar 15 and the movable plate 16 to move through the slide rail bar 12, thereby driving the edge banding strip 13 and multiple components to move, thereby completely edge banding one end of the plate, and when the movable plate 16 moves, it will drive the suspension rod 21, the two rotating rods 23 and the two grinding heads 22 to move, and when the gear 18 moves, it will engage with the rack 17 to rotate the two rotating rods 23 and the two grinding heads 22, and the upper and lower sides of the welded aluminum edge banding will be polished simultaneously by the grinding head 22.

[0063] Specific reference Fig. 9 and Fig.10 The spring preload mechanism includes a U-shaped frame 29, an adjusting bolt 30, a spring 31, a first sliding plate 32, and a second sliding plate 33. An integrally formed second sliding plate 33 extends from the side of the U-shaped frame 29. The second sliding plate 33 is slidably connected to a sliding groove provided on the side of the mounting rod 19. The second sliding plate 33 is connected to the first sliding plate 32 through two symmetrically arranged springs 31. The adjusting bolt 30 is threaded through the rear side of the mounting rod 19 and enters the sliding groove in the mounting rod 19. The adjusting bolt 30 can be rotated to resist the rotating groove on the first sliding plate 32 and then push the first sliding plate 32 to squeeze the spring 31. No thread is processed near the end of the adjusting bolt 30.

[0064] In this embodiment: when the spring 31 is in a natural state, the distance between the first sliding plate 32 and the second sliding plate 33 is determined by the initial length of the spring, and the adjusting bolt 30 enters the sliding groove in the mounting rod 19 by rotation and abuts against the rotating groove on the first sliding plate 32. When the adjusting bolt 30 continues to rotate inward, it pushes the first sliding plate 32 closer to the second sliding plate 33, thereby compressing the spring 31. After the spring 31 is compressed, a greater elastic force is generated, thereby increasing the preload force, which is transmitted to the roller body 25 through the U-shaped frame 29, so that the roller can stably press the aluminum strip against the plate. By adjusting the screw-in depth of the bolt 30, the size of the preload force can be controlled to meet the requirements of edge banding of different thicknesses.

[0065] Specific reference Figure 1 , Figure 3 , Figure 4 , Figure 5 The abutment strip 14 is telescopically arranged on the upper inner wall of the abutment hole 10, and a limit plate 3 is arranged on the edge of the edge banding table 2 near the coupling pulse welding gun head 20 for lifting and lowering. The limit plate 3 is linked with the abutment strip 14, and a series plate is fixed on the top of multiple abutment strips 14. Two ends of the series plate are respectively fixedly connected to two connecting rods 28 in the vertical direction, and the two ends of the limit plate 3 are respectively fixedly connected to the two connecting rods 28. The two connecting rods 28 are respectively slidably connected to the inner walls of the two sliding grooves 24 in the assembly shell 9. The side of the assembly shell 9 is fixedly connected to the control mechanism 4, and the control mechanism 4 is used to control the operation of various mechanisms of the edge banding operation. A plurality of spacings are provided between the vertical plate surface of the limit plate 3 and the edge of the edge banding table 2, and the lifting mechanism of the limit plate 3 is arranged in the assembly shell 9.

[0066] In this embodiment: when the plate is placed on the edge banding table 2, the control mechanism 4 is first used to start the telescopic action of the abutment bar 14 to press the plate. Subsequently, the limit plate 3 is retracted downward through the linkage of the connecting rod 28 to ensure that the height of the limit plate is lower than the edge banding table 2, so as not to affect the welding operation. After the welding is completed, the abutment bar 14 and the limit plate 3 are reset at the same time to release the plate. The limit plate 3 is arranged in linkage with the abutment bar 14 to simultaneously limit and fix the plate through collaborative work, saving operation time and improving work efficiency. The control mechanism 4 is used to control the operation of various mechanisms of the edge banding operation to ensure the automation and precise control of the entire edge banding process. A number of spacings are provided between the vertical plate surface of the limit plate 3 and the edge of the edge banding table 2 to leave enough operating space during the edge banding process.

[0067] For details, please refer to Figure 2The coiling mechanism includes a winding seat 7, a locking column 8, a limiting bracket 6, a limiting column 5, and a base plate. The upper end of the base plate is fixedly connected to the winding seat 7. The edge banding strip 13 is wound on the winding seat 7. The winding seat 7 is provided with a locking groove for the locking column 8 to be engaged. The limiting bracket 6 is fixedly connected to the locking column 8. The top of the limiting column 5 is provided with a groove for the limiting bracket 6 to be inserted.

[0068] In this embodiment: the components of the coiling mechanism are arranged on the base, and the winding seat 7 is fixedly connected to the upper end of the base plate. Its main function is to coil the edge banding strip 13. The top of the limiting column 5 is provided with a groove for inserting the limiting bracket 6, which further fixes the position of the limiting bracket 6 and ensures the stability of the entire coiling mechanism. The locking column 8 enters the locking groove by locking to complete the fixation of the limiting bracket 6.

[0069] For details, please refer to Figure 1 The abutment bar 14 is curved and fits the edges and corners of the plate. The rail bar 12 is convex and the sliding bar 15 is concave. The sliding bar 15 is slidably arranged on the rail bar 12. The grinding head 22 is semi-spherical and made of wear-resistant material. The suspension rod 21 is L-shaped and made of alloy steel.

[0070] In this embodiment, the curved shape of the abutting strip 14 can make the edges and corners of the plate fit more closely, and the "concave and convex" shapes of the slide rail strip 12 and the slide strip 15 can achieve high-precision sliding fit.

[0071] The working principle and use process of the present invention are as follows: when the plate needs to be edge-sealed with aluminum strips, on the edge-sealing table 2, one end of the plate will be abutted against the limiting plate 3, and the vertical plate surface of the limiting plate 3 will be fitted with the welding surface of the plate, and then the control mechanism 4 will control the abutting strip 14 to press the plate down, and at the same time, the limiting plate 3 will be retracted downward through its lifting mechanism, so that the height of the limiting plate 3 is lower than the height of the edge-sealing table 2, and the plate is limited and fixed by pressing the plate against the abutting strip 14 and the limiting plate 3 retracting downward, and the plate After the fixing is completed, the edge banding strip 13 is unfolded by the traction roller arranged at the upper end of the movable plate 16 to extend it to the welding area. The unfolded edge banding strip 13 is located between the two coupled pulse welding gun heads 20, ready for welding. The roller body 25 provides a pre-tightening force through the spring pre-tightening mechanism to press the edge banding strip 13 against the surface to be welded of the plate to ensure that the edge banding strip and the plate are closely fitted. Then, the edge banding strip 13 is welded to one end of the plate by the coupled pulse welding gun head 20 to perform the edge banding process, and the control mechanism 4 controls the motor drive The movable sliding bar 15 slides along the slide rail bar 12 to realize the movement of the movable plate 16, thereby driving the edge banding strip 13 and multiple components to move, and gradually completing the edge banding operation on one side of the plate. During the movement of the movable plate 16, the suspension rod 21, the rotating rod 23 and the grinding head 22 move synchronously with the movable plate 16, and the gear 18 is engaged with the rack 17 to drive the rotating rod 23 and the grinding head 22 to rotate, and the upper and lower sides of the welded aluminum edge banding are simultaneously subjected to the initial grinding treatment to remove larger welding slag and burrs. When the movable plate 16 moves to the end of the plate, After completing the entire edge banding operation, the welding gun head 20 stops working. After standing still for a period of time, the control mechanism 4 controls the motor to drive the sliding bar 15 to slide along the sliding rail bar 12 and then drives the movable plate 16 to return to the initial position. The moving speed of the movable plate 16 returning is higher than the moving speed during the welding edge banding. On the way back, the movable plate 16 will drive the grinding mechanism to perform a secondary grinding on the welded edge banding to remove the fine burrs and uneven parts that may remain after the initial grinding, ensure the perfect fit between the edge banding strip and the plate, and optimize the surface quality of the edge banding strip.

A method for using a welding aluminum edge sealing device, characterized in that: The aluminum edge welding device described in claim 9 is used, comprising the following steps: S1: When the plate needs to be edge-sealed with aluminum strips, the plate is placed on the edge-sealing table (2) of the mounting shell (1). At this time, one end of the plate will be pressed against the limiting plate (3), and the vertical plate surface of the limiting plate (3) will be pressed against the welding surface of the plate. Then, the control mechanism (4) controls the abutting strip (14) to press the plate downward. At the same time, the limiting plate (3) is retracted downward through its lifting mechanism, so that the height of the limiting plate (3) is lower than the height of the edge-sealing table (2). The plate is limited and fixed by the abutting strip (14) pressing the plate downward and the limiting plate (3) retracting downward; S2: After the plate is fixed, the edge banding strip (13) is unfolded by a traction roller arranged at the upper end of the movable plate (16), so that the unfolded edge banding strip (13) is located between the two coupled pulse welding gun heads (20), and then the edge banding strip (13) is welded to one end of the plate by the coupled pulse welding gun head (20) to perform edge banding processing, and the sliding bar (15) and the movable plate (16) are driven to move by the slide rail bar (12), thereby driving the edge banding strip (13) and multiple components to move, so as to completely perform edge banding processing on one end of the plate; S3: When the movable plate (16) moves, it drives the suspension rod (21), the two rotating rods (23) and the two grinding heads (22) to move, and when the gear (18) moves, it meshes with the rack (17), causing the two rotating rods (23) and the two grinding heads (22) to rotate, and the two sides of the aluminum edge are polished simultaneously by the upper and lower grinding heads (22).
