Description

Technical Field

[0001] The present invention relates to the technical field of aluminum plate welding, and in particular to aluminum plate welding equipment with a protective structure. Background Art

[0002] Aluminum sheet is a thin sheet or plate made by rolling aluminum alloys. It possesses excellent physical and chemical properties, such as light weight, high strength, corrosion resistance, and good electrical and thermal conductivity. This has led to its widespread use in a wide range of fields, including aerospace, automotive, construction, electronic equipment, and packaging. However, many applications require the assembly of aluminum sheets into more complex structures or components, necessitating the use of aluminum sheet welding equipment to connect the sheets. However, existing aluminum sheet welding equipment has several drawbacks.

[0003] For example, the invention patent with publication number CN118143492B discloses a local hot-melt welding device for curtain wall aluminum panels, including a frame and a welding head, a receiving platform, a cooling mechanism, a protective cover, a limiting mechanism, a welding mechanism, a grinding mechanism, a distance-adjusting mechanism, and a cleaning mechanism. The receiving platform is arranged on the frame, the cooling mechanism is used to cool the aluminum panel, the protective cover can be raised and lowered on the frame, the limiting mechanism is used to limit the aluminum panel, the welding mechanism is used to drive the welding head to weld the four corners of the aluminum panel, the grinding mechanism is used to grind the four corners of the aluminum panel, the grinding mechanism includes a lifting frame, an internal grinding component, and an external grinding component, and the distance-adjusting mechanism is used to adjust the distance between the four welding mechanisms and the four grinding mechanisms.

[0016] The working principle and beneficial effects of the present invention are:

[0017] By arranging the second connecting rod, the first rotating plate, the second slide, the first rotating sleeve, the first connecting shaft, the second rotating plate, the second rotating sleeve and the second connecting shaft, when the first motor on the device drives the eccentric wheel to rotate, the eccentric wheel will intermittently push the pressure rod to the right, thereby causing the second slide to slide to the right. After the first connecting shaft above the second slide abuts against the baffle, it will cause the first rotating plate to rotate counterclockwise, thereby driving the supporting plate to move upward, so that the device can automatically transport the aluminum plate to the welding area for welding processing, realizing the functions of automatic feeding and lifting, and after the device lifts the aluminum plate to the appropriate position, the second electric push rod can be used to adjust the position of the outer shell, so that the device can play a protective effect during use and can also block strong light.

[0018] The device is provided with a feeding assembly, and the aluminum plates can be stacked and placed inside the feeding assembly. Then, the position of the first slide is adjusted by extending or shortening the first electric push rod, thereby changing the size of the internal space of the outer frame to adapt to automatic feeding and welding of aluminum plates of different sizes. This solves the problem that existing welding devices cannot adapt to automatic feeding of aluminum plates of different sizes. The device has the advantage of greater adaptability.

[0019] The device is provided with a cleaning component. The grinding plate at the bottom of the cleaning component can automatically grind the surface of the aluminum plate when the aluminum plate passes through. Under the action of the first spring, the grinding plate can ensure the pressing effect of the aluminum plate, and the beveled surfaces on the left and right sides of the grinding plate and the third slide plate make the aluminum plate automatically push the grinding plate upward when passing through the grinding plate, so as to remove the oxide layer on the surface of the aluminum plate before welding the aluminum plate, thereby ensuring the welding quality of the device. The device can remove the oxide layer while automatically feeding, thereby improving the processing efficiency of the aluminum plate.

[0020] The device is provided with a guide assembly and an adjustment assembly. The guide assembly can transport the aluminum plate vertically downward. The distance between the two side plates is adjusted by the first screw to adapt to the longitudinal transportation of aluminum plates of different lengths. After the aluminum plate moves down to the horizontal aluminum plate, the third screw can be driven to rotate by the second motor. When the third screw rotates, the welding gun will slide back and forth, thereby realizing the welding function. After the welding is completed, as the eccentric wheel continues to rotate, the support plate moves down, and the strong magnet adsorbs the support plate to reset the support plate for the next welding work.

DETAILED DESCRIPTION

[0033] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 any creative efforts are within the scope of protection of the present invention.

[0034] Example 1: Figures 1-10As shown, this embodiment proposes an aluminum plate welding device with a protective structure, including a first bracket 1, a first motor 2 is installed on the first bracket 1, a second bracket 8 is provided on the right side of the first bracket 1, a first connecting rod 3 is fixedly connected to the output shaft of the first motor 2, an eccentric wheel 4 is fixedly connected to the first connecting rod 3, a pressure rod 6 is abutted on the right side of the eccentric wheel 4, a fixing plate 9 is fixedly connected to the bottom of the second bracket 8, a first connecting tube 10 is fixedly provided on the fixing plate 9, a first spring 7 is fixedly connected between the first connecting tube 10 and the pressure rod 6, and when the device is in use, the first motor 2 drives the first connecting rod 3 to rotate, thereby driving the eccentric wheel 4 to rotate, and the eccentric wheel 4 can push the pressure rod 6 when rotating, so that the first spring 7 is compressed, thereby driving the pressure rod 6 to slide in the first connecting tube 10. The second bracket 8 is equipped with a connecting assembly 12, which can support the remaining horizontal aluminum plates after one of the aluminum plates is transported. The pressure rod 6 is fixedly connected to the second connecting rod 16, and the first rotating plate 17 is rotatably installed on the second connecting rod 16. The second slide 18 is slidably installed on the fixed plate 9, and the second rotating plate 21 is rotatably installed on the second slide 18. The first rotating plate 17 and the second slide 18 are rotatably connected. The front and rear sides of the first rotating plate 17 are respectively rotatably installed with the first rotating sleeve 19 and the first connecting shaft 20, and the front and rear sides of the second rotating plate 21 are respectively rotatably installed with the second rotating sleeve 22 and the second The connecting shaft 23, the tops of the first rotating sleeve 19 and the second rotating sleeve 22 are fixedly connected to the supporting plate 13, the second bracket 8 is fixedly connected to the baffle 14, and a guide plate 25 is fixedly provided below the baffle 14. The second bracket 8 is installed with a feeding assembly 15, and a second electric push rod 26 is installed on the feeding assembly 15. The second electric push rod 26 is connected to a housing 27, and a cleaning assembly 28 and a guide assembly 29 are installed on the housing 27. A third electric push rod 30 is installed on the guide assembly 29, and an adjusting assembly 31 is installed below the third electric push rod 30, and a welding gun 24 is installed below the adjusting assembly 31. During the process of sliding to the right, the pressure rod 6 can drive the second connecting rod 16 to slide to the right, and the second connecting rod 16 will drive the second slide plate 18 to move to the right until the first connecting shaft 20 abuts against the baffle 14. After the first connecting shaft 20 is blocked, as the second slide plate 18 continues to slide to the right, the first rotating plate 17 and the second rotating plate 21 will rotate counterclockwise, thereby continuously lifting the support plate 13 and the aluminum plate above it. The vertical aluminum plate falling from the guide assembly 29 will fall on the horizontal aluminum plate on the support plate 13. Subsequently, the welding gun 24 can be continuously moved by adjusting the assembly 31 to perform welding work.

[0035] Example 2: Figures 1-10 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes an aluminum plate welding device with a protective structure.

[0036] In this embodiment, a groove 5 for docking with the pressure rod 6 is provided on the eccentric wheel 4. The side of the pressure rod 6 close to the eccentric wheel 4 is a hemispherical structure. A second connecting tube 11 is fixedly provided on the first connecting tube 10. The pressure rod 6 and the first connecting tube 10 and the second connecting tube 11 are all slidingly connected. The groove 5 can make the left side of the pressure rod 6 always maintain abutment state with the eccentric wheel 4, and the pressure rod 6 can intermittently slide left and right as the eccentric wheel 4 rotates.

[0037] In this embodiment, the connecting component 12 includes a connecting frame 1203 fixedly connected to the fixed plate 9, and a guide block 1202 is slidably installed on the connecting frame 1203. A push plate 1201 is fixedly connected to the bottom of the guide block 1202. A strong magnet 1204 is installed on the side of the push plate 1201 close to the supporting plate 13. The material of the supporting plate 13 is a magnetic metal material. Ball bearings 1205 are evenly arranged on the push plate 1201. When the push plate 1201 supports the remaining aluminum plate, the ball bearings 1205 can reduce the resistance of the push plate 1201 when it moves, thereby ensuring that the magnetic force between the supporting plate 13 and the strong magnet 1204 is sufficient to adsorb the push plate 1201 for sliding.

[0038] In this embodiment, the thickness of the push plate 1201 is greater than the thickness of the support plate 13. When the support plate 13 and the push plate 1201 are adsorbed on each other, the support plate 13 forms a lifting structure with the outer shell 27 through the first rotating plate 17, the first connecting shaft 20, the second rotating plate 21 and the second connecting shaft 23. The purpose of the thicker thickness of the push plate 1201 is to ensure that the push plate 1201 can push the aluminum plate on the support plate 13 to the right and support the remaining aluminum plates when it moves with the support plate 13, so as to facilitate subsequent feeding one by one.

[0039] In this embodiment, the feeding assembly 15 includes an outer frame 1501 and a connecting shell 1503 fixedly connected to the second bracket 8. A first slide 1502 is slidably mounted on the outer frame 1501. A first electric push rod 1504 is fixedly connected between the connecting shell 1503 and the first slide 1502. The connecting shell 1503 and the second electric push rod 26 are fixedly connected. By extending or shortening the first electric push rod 1504, the position of the first slide 1502 in the outer frame 1501 is changed, so that the device can adapt to the use of aluminum plates of different lengths, thereby enhancing the functionality of the device.

[0040] In this embodiment, the cleaning component 28 includes a third slide 2801 slidably installed in the outer shell 27, and a convex plate 2804 is fixedly connected to the third slide 2801, and a slide rod 2805 is fixedly provided on the convex plate 2804. A fixed cylinder 2807 is fitted on the outer side of the slide rod 2805, and the fixed cylinder 2807 and the outer shell 27 are fixedly connected. A fourth slide 2802 is slidably installed below the third slide 2801, and a grinding plate 2803 is fixedly provided at the bottom of the fourth slide 2802. A second spring 2806 is fixedly installed between the slide rod 2805 and the fixed cylinder 2807. As the aluminum plate moves to the right, the second spring 2806 can press down the third slide 2801, so that the grinding plate 2803 below the fourth slide 2802 grinds the oxide layer on the surface of the aluminum plate to ensure the subsequent welding effect.

[0041] In this embodiment, beveled surfaces are provided on the left and right sides of the fourth slide 2802 and the polishing plate 2803. The length of the fourth slide 2802 is greater than the length of the third slide 2801. The third slide 2801, the convex plate 2804 and the slide rod 2805 are fixedly connected as an integral structure to ensure the overall stability of the device. The beveled surface facilitates pushing the fourth slide 2802 and the polishing plate 2803 upward after the aluminum plate rests on the beveled surfaces of the fourth slide 2802 and the polishing plate 2803, thereby improving the device's effect in removing the oxide layer.

[0042] In this embodiment, the guide assembly 29 includes a guide frame 2901 fixedly connected to the right side of the shell 27, and a first screw 2902 is installed on the side thread of the guide frame 2901, and a side plate 2903 is rotatably installed on the first screw 2902, and a second screw 2904 is installed on the middle thread of the guide frame 2901, and a first flexible abrasive belt 2905 is rotatably installed on the second screw 2904. A second flexible abrasive belt 2906 is fixedly arranged in the guide frame 2901. By placing the vertically placed aluminum plate to be welded inside the guide frame 2901, the device can cooperate with the horizontal aluminum plate for welding. The position of the side plate 2903 in the guide frame 2901 can be adjusted by rotating the first screw 2902 to adapt to the transportation and welding of vertical aluminum plates of different lengths. The second screw 2904 is used to change the degree of pressure of the first flexible abrasive belt 2905 on the vertical aluminum plate, so that the aluminum plate can fall normally and the oxide layer on the surface of the aluminum plate is polished.

[0043] In this embodiment, the side plate 2903 forms a sliding structure between the first screw 2902 and the guide frame 2901, and the position of the side plates 2903 on both sides of the device is changed by the sliding structure on the device. The first screw 2902 and the side plate 2903 are symmetrically distributed on both sides of the guide frame 2901. The symmetrically distributed first screw 2902 and side plate 2903 can change the conveying position of the aluminum plate, thereby adapting to the horizontal aluminum plate in the corresponding position for welding.

[0044] In this embodiment, the adjustment assembly 31 includes a lap plate 3101 fixedly connected to the bottom of the third electric push rod 30, and a second motor 3102 is fixedly connected to the lap plate 3101, and a third screw 3103 is fixedly connected to the output shaft of the second motor 3102. The outer thread of the third screw 3103 is installed with an outer sleeve 3104, and the outer sleeve 3104 and the lap plate 3101 are in a sliding connection, and the lap plate 3101 and the welding gun 24 are in a fixed connection. The third electric push rod 30 is used to adjust the height of the lap plate 3101 and the welding gun 24, and the third screw 3103 is driven to rotate by the second motor 3102 to adjust the position of the outer sleeve 3104, so that the welding gun 24 can slide left and right, so that the device can weld two aluminum plates that are perpendicular to each other.

[0045] Specifically, the present invention is an aluminum plate welding device with a protective structure, first, as Figure 1-Figure 7 As shown, when the device is in use, the first motor 2 on the first bracket 1 drives the first connecting rod 3 to rotate, thereby driving the eccentric wheel 4 to rotate. When the eccentric wheel 4 rotates, it pushes the pressure rod 6 through the inner wall of the groove 5. The pressure rod 6 moves to the right to compress the first spring 7, thereby driving the pressure rod 6 to slide in the first connecting tube 10 and the second connecting tube 11. In the process of sliding to the right, the pressure rod 6 can drive the second connecting rod 16 to slide to the right. The second connecting rod 16 will drive the second slide plate 18 to move to the right. At this time, the second connecting rod 16 and the first rotating plate 17 are , the second slide plate 18, the first rotating sleeve 19, the first connecting shaft 20, the second rotating plate 21, the second rotating sleeve 22 and the second connecting shaft 23 drive the supporting plate 13 to move to the right as a whole. When the supporting plate 13 moves to the right, the strong magnet 1204 will be adsorbed on the supporting plate 13 and push the aluminum plate on the supporting plate 13 to the right through the push plate 1201. The guide block 1202 slides in the connecting frame 1203 at this time. The push plate 1201 can support the remaining horizontal aluminum plate in the outer frame 1501, and the ball 1205 can reduce the resistance of the push plate 1201 when it moves. When the aluminum plate on the support plate 13 passes under the housing 27, the aluminum plate can abut against the beveled surface of the grinding plate 2803 under the fourth slide 2802, thereby pushing the grinding plate 2803 upward. At this time, the second spring 2806 between the slide rod 2805 and the fixed cylinder 2807 is compressed, and the convex plate 2804 moves upward, realizing the grinding function of the oxide layer on the surface of the aluminum plate. This device can adapt to the transportation of aluminum plates of different lengths, such as Figure 3 and Figure 8As shown, by extending or shortening the first electric push rod 1504 on the connecting shell 1503, the position of the first slide 1502 within the outer frame 1501 is changed, so that the cavity between the outer frame 1501 and the first slide 1502 can accommodate aluminum plates of different lengths for placement and automatic blanking. By rotating the first screw 2902, the position of the side plate 2903 within the guide frame 2901 is adjusted, allowing the device to accommodate vertical aluminum plates of different lengths for conveying and welding. The second screw 2904 is used to change the degree of pressure of the first flexible abrasive belt 2905 on the vertical aluminum plate, allowing the aluminum plate to fall normally and polishing the oxide layer on the aluminum plate surface.

[0046] like Figure 4-10 As shown, after the first connecting shaft 20 moves to abut against the baffle 14, as the second slide plate 18 continues to slide to the right, the first rotating plate 17 and the second rotating plate 21 will rotate counterclockwise, thereby continuously lifting the support plate 13 and the aluminum plate above it. The vertical aluminum plate dropped from the guide assembly 29 will fall on the horizontal aluminum plate on the support plate 13. The third electric push rod 30 is extended or shortened according to the required welding position, so that the welding gun 24 is aligned with the welding area. The third screw rod 3103 is driven to rotate by the second motor 3102, so that the outer bushing 3104 drives the welding gun 24 to continue to move under the lap plate 3101, and then the position of the outer bushing 3104 is adjusted so that the welding gun 24 can slide left and right, thereby welding two aluminum plates that are perpendicular to each other. The eccentric wheel 4 rotates half a circle and continues to rotate. Under the action of the first spring 7, the pressure rod 6 will move to the left again and return to Figure 1 In the state, the two welded aluminum plates can fall onto the guide plate 25 below the baffle 14 and slide down. When the device is in use, the position of the housing 27 can be changed by the second electric push rod 26. The baffles 14 and the housing 27 on both sides of the welding gun 24 can play a protective role during welding.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
