[0002] Welding is an essential step in the manufacturing of aluminum alloy blinds. Traditional welding methods typically rely on manual or semi-automated welding equipment, which is inadequate for window frames of varying specifications and sizes. This results in low efficiency and poor weld quality. Especially for heat-sensitive materials like aluminum alloy, the welding process requires strict control of temperature, pressure, and speed to avoid defects such as deformation, cracks, and porosity.

[0003] Most existing welding devices use fixed workbenches that cannot be flexibly adjusted to accommodate window frames of different sizes and shapes. This results in the need to frequently replace fixtures or adjust welding parameters when welding blinds of different specifications, which not only increases the difficulty of operation but also prolongs the production cycle. In addition, traditional welding devices usually require manual flipping of the window frame when welding both sides of the window frame, which not only increases labor intensity but also increases safety risks.

[0004] Therefore, the present application provides a welding device for aluminum alloy shutters to meet the needs. Utility Model Content

DETAILED DESCRIPTION

[0026] The following describes in detail a welding device for aluminum alloy Venetian blinds provided by the present invention, with reference to the accompanying drawings and specific embodiments. It is also noted that, for the sake of completeness, the following embodiments are best and preferred embodiments. For some known technologies, those skilled in the art may employ alternative implementations. Furthermore, the accompanying drawings are provided solely for the purpose of illustrating the embodiments in greater detail and are not intended to limit the present invention.

[0027] like Figure 1 - Figure 7 As shown, an embodiment of the present invention provides a welding device for aluminum alloy shutters, including: a welding bed 1, which serves as the basic support platform of the entire welding device to ensure stability during the welding process, and is composed of two side platforms fixed parallel to each other, and a flip assembly driven by a motor is provided on the side platform.

[0028] The flip plate 2 is installed in the middle of the two side platforms of the welding bed 1 through rotating connectors such as bearings or hinges. Both ends are fixedly connected to the flip assembly and can rotate around a fixed axis. The maximum flip angle of the flip plate 2 is 180°, which is convenient for flipping the entire installed window frame, thereby welding both sides of the window frame.

[0029] There are multiple sliding plates 3, which are all slidably connected with the flip plate 2. The multiple sliding plates 3 are arranged parallel to each other and perpendicular to the flip plate 2. They are used to provide sliding tracks for the welding table 4, so as to realize flexible adjustment of the welding table 4 in the horizontal direction. By adjusting the distance between each sliding plate 3 and the number of sliding plates 3 used, the overall placement of window frames of different sizes and styles can be adapted.

[0030] The welding platform 4 is slidably connected to the sliding plate 3 and can be adjusted in position as needed to build a platform for supporting the window frame. There are several welding platforms 4, and the top of each welding platform 4 is on the same plane to ensure the flatness and consistency of the welded parts. Among them, the welding platform 4 is provided with a double-sided transparent welding groove (not shown in the figure) to facilitate welding the reverse side of the welded part after the flip plate 2 is turned over.

[0031] The positioning plate 17 is used to accurately position the window frame components to ensure welding accuracy. It is set on the top of the welding table 4. The positioning plates 17 on multiple welding tables 4 cooperate with each other to form a placement groove for placing the entire window frame. The positioning plates 17 and the welding table 4 are detachably connected. The width of the placement groove can be adjusted by adjusting the distance between the positioning plates 17 on the same welding table 4 to adapt to the fixation of welding components of different widths.

[0032] Furthermore, the welding device also includes a welding robot for welding, which controls the welding trajectory through program programming to adapt to the welding of window frames of different specifications, and a positioning fixture for pressing downwards and cooperating with the welding table 4 to fix the upper and lower surfaces of the welded parts to prevent the welded parts from falling off the welding table 4 after the flip plate 2 is flipped.

[0033] By arranging a sliding plate 3 and a welding table 4 with movable adjustment of the mutual spacing on the welding bed 1, it is convenient to cope with the positioning and clamping of shutter frames of different specifications (such as 6-piece and 8-piece) and different sizes, and in conjunction with the flip plate 2 that can be flipped 180°, fully automatic front and back welding of the window frame can be achieved, which not only reduces the labor cost, but also improves the welding efficiency of the window frame.

[0034] like Figure 4 As shown, it also includes guide rails 5, two of which are symmetrically fixed on the lower side walls of the flip plate 2, and positioning grooves 11 are evenly opened at the upper and lower ends of the guide rails 5; it also includes a fixed plate 9, which is fixed to the bottom of the sliding plate 3 through a curved arm 8. There are two fixed plates 9, and they are symmetrically arranged at the bottom of the sliding plate 3. The two fixed plates 9 are rotatably connected to the opposite side of the two fixed plates 9. There are multiple rollers 10, and they are distributed in a rectangular array on the fixed plate 9. The rollers 10 are rollingly connected with the positioning grooves 11 to achieve smooth sliding of the sliding plate 3 on the flip plate 2.

[0035] like Figure 4As shown, it also includes: a rack 6, which is arranged on the upper side of the flip plate 2; a second motor 12, which is fixed to the bottom of the sliding plate 3; a gear 13, which is fixedly connected to the output end of the second motor 12 and is engaged with the rack 6.

[0036] The second motor 12 drives the gear 13 to engage with the rack 6 , thereby achieving automatic sliding adjustment of the sliding plate 3 on the flip plate 2 .

[0037] like Figure 6 As shown, it also includes: a first motor 7, fixed at the end of the sliding plate 3; a screw rod 14, rotatably connected to the top of the sliding plate 3, and one end is connected to the output end of the first motor 7; a nut seat 15, fixedly connected to the welding table 4, and the nut seat 15 is threadedly connected to the screw rod 14; a slide rail 16, arranged at the top of the sliding plate 3, and slidingly connected to the bottom of the welding table 4.

[0038] The first motor 7 drives the screw rod 14 to rotate, and the nut seat 15 is threadedly connected to the screw rod 14 to achieve vertical lifting and adjustment of the welding platform 4 on the sliding plate 3. The slide rail 16 ensures the stability of the welding platform 4 during the lifting process.

[0039] Among them, three welding platforms 4 arranged in a straight line are provided on a single sliding plate 3. The welding platforms 4 at both ends are threadedly connected to the same screw rod 14 through a nut seat 15, and the screw rod 14 is a bidirectional screw rod 14. By rotating the bidirectional screw rod 14, the two welding platforms 4 at both ends can achieve synchronous linear sliding close to or away from each other. The welding platform 4 in the middle is threadedly connected to another screw rod 14 through a nut seat 15, and the two screw rods 14 are independently driven by two first motors 7 respectively.

[0040] When dealing with a 6-branch window frame, that is, four parallel longitudinal branches are arranged between two horizontally parallel branches, it is only necessary to adjust the spacing between the four sliding plates 3 and the distance between the welding platforms 4 located at both ends of the sliding plates 3 to complete the positioning and clamping of the entire window frame component.

[0041] When dealing with 8-branch window frames, that is, relative to 6-branch window frames, a short horizontal rod support is installed between the two longitudinal supports at both ends (refer to Figure 2 ), at this time, it is necessary to adjust the position of the welding table 4 located in the middle of the sliding plate 3 to ensure the lateral fixation of the two short rod lateral supports.

[0042] This invention encompasses any alternatives, modifications, equivalents, and solutions that do not depart from the spirit and scope of this invention. While specific details are described in detail in the preferred embodiments of this invention to provide a thorough understanding, those skilled in the art will be able to fully understand this invention without these details. Furthermore, to avoid unnecessary confusion regarding the essence of this invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
