Description

Technical Field

[0001] The present invention relates to the field of welding, and in particular to a multi-station BOSS post welding device. Background Art

[0002] In the field of automotive interior manufacturing, Boss posts, as key connecting structural parts to be processed, are widely used in the assembly of components such as instrument panels, door panels, and center consoles. In traditional production processes, a manual hand-held welding device or a fixed robotic arm equipped with a welding torch is usually used to weld and fix the Boss post to the base material.

[0003] However, in the prior art, most automotive interior parts are complex shaped curved surface structures, and the spatial distribution of their Boss posts has non-standard characteristics; existing molds are difficult to position and fix, and the welding process adopts a single-piece flow mode. After each single-piece welding is completed, the workpiece needs to be manually disassembled and a new workpiece needs to be repositioned; during this process, the welding device is in a forced standby state, resulting in a significant reduction in the proportion of the effective working time of the device (seriously restricting the production line rhythm). Summary of the Invention

[0004] In view of the above problems, the present invention provides a multi-station BOSS post welding device to continuously carry out welding work, improve the effective working time of the welding device, and improve production efficiency and processing consistency.

[0006] The rotating platform includes a support plate and a driving motor. The support plate is rotatably arranged inside the frame. The movable end of the driving motor is meshed with the edge of the support plate to drive the support plate to rotate inside the frame. Above the support plate, a plurality of processing stations are arranged;

[0007] The positioning mold includes a profiling block. Above the profiling block, a profile of the front surface of the structural part to be processed is provided. During processing, the positioning mold is located at the processing station on the support plate;

[0008] The welding assembly is arranged close to the rotating platform. The welding assembly includes a robotic arm and a welding device fixed to the movable end of the robotic arm.

[0009] Preferably, two positioning blocks are arranged on the support plate, and the area between the two positioning blocks is the processing station.

[0010] Preferably, the positioning mold includes a mounting plate. The profiling block is arranged above the mounting plate, and handles are installed on both sides of the mounting plate opposite to the profiling block.

[0024] As Figure 1 shown, the present invention provides a multi-station BOSS post welding device, including a frame 1, in which a rotating platform 2, a positioning die 3, and at least one welding assembly 4 are provided;

[0025] The rotating platform includes a support plate 21 and a driving motor 22. The support plate 21 is rotatably arranged inside the frame 1. The movable end of the driving motor 22 is meshed with the edge of the support plate 21 to drive the support plate 21 to rotate inside the frame 1. A plurality of processing stations are arranged above the support plate 21;

[0026] As Figure 2 shown, the positioning die 3 includes a profiling block 31. The profiling of the front surface of the workpiece to be processed is provided above the profiling block 31. During processing, the positioning die 3 is located at the processing station on the support plate 21;

[0027] The welding assembly 4 is arranged at a position close to the rotating platform 2. The welding assembly 4 includes a robotic arm and a welding device fixed to the movable end of the robotic arm.

[0028] In this embodiment, during processing, the workpiece to be welded is placed on the positioning die 3 outside the frame 1, and then the entire positioning die 3 is placed at the processing station on the support plate 21. The driving motor 22 is driven to rotate the support plate 21, so that the positioning die 3 is close to the position of the welding assembly 4. Finally, the robotic arm of the welding assembly 4 drives the welding device to weld the BOSS post on the workpiece to be processed; it can be understood that since there are a plurality of processing stations on the support plate 21, when the welding device welds the BOSS post, the driving motor 22 is in the off state. At this time, the positioning die 3 with the workpiece to be processed can continue to be placed at the next processing station on the support plate 21. After the welding device welds the previous workpiece to be processed, the driving motor 22 continues to drive the support plate 21 to rotate, so as to rotate the next positioning die 3 with the workpiece to be processed to a position close to the welding assembly 4. In this way, the welding assembly 4 will not be in an idle waiting state, effectively improving the effective working time of the welding assembly.

[0029] There are two positioning blocks arranged on the support plate 21, and the area between the two positioning blocks is the processing station.

[0030] In this embodiment, the positioning blocks can be in a 7-shaped structure, and the two positioning blocks are arranged oppositely, so that when the positioning die is placed on the support plate, it can be limited by the positioning blocks, which is beneficial for the manipulator of the subsequent welding assembly to perform welding on the preset moving track.

[0031] In a specific embodiment, as Figure 2 shown, the positioning die 3 includes a mounting plate 32, the profiling block 31 is arranged above the mounting plate 32, and handles 33 are mounted on both sides of the mounting plate 32 opposite to the profiling block 31.

[0032] In this embodiment, it can be understood that the die is generally made of metal material and has a certain weight itself. Through the arrangement of the handles 33, it is beneficial to place the positioning die 3 on the support plate 21.

[0033] In a specific embodiment, pressing devices are mounted on both sides of the mounting plate 32 opposite to the profiling block 31.

[0034] It can be understood that the profiling above the profiling block 31 can only play a role in limiting the structure to be processed. During welding, affected by the acting force, the structure to be processed is prone to displacement, thus affecting the welding accuracy. Especially for the special-shaped curved surface structure, it is also prone to warping during welding, and even the welding assembly 4 cannot be positioned on multiple BOOS columns on the structure to be processed according to the preset moving track. In this embodiment, through the arrangement of the pressing devices, the structure to be processed can be fixed on the profiling block to avoid the influence of displacement and warping.

[0035] In a specific embodiment, the pressing device includes a pressing cylinder 341, the pressing cylinder 341 is connected with a connecting plate 342 through a connecting block, and a plurality of telescopic rods 343 are mounted below the connecting plate 342.

[0036] In this embodiment, the pressing cylinder 341 can at least drive the connecting plate 342 to displace in the vertical direction, so that the telescopic rods 343 can move up and down. During the pressing process, the connecting plate 342 drives the telescopic rods 343 to move downward. When dealing with the structure to be processed with a special-shaped curved surface, the telescopic degrees of the plurality of telescopic rods 343 are different, so that the plurality of telescopic rods 343 can apply pressure to each point on the curved surface of the structure to be processed, so as to adapt to the curved surfaces of various special-shaped structures, thereby realizing fixing the structure to be processed on the profiling block 31.

[0037] In a specific embodiment, the pressing cylinder 341 has a flipping function, and the model of the pressing cylinder is: JSK50AK.

[0038] In this embodiment, through the flipping function of the pressing cylinder 341, not only can the connecting plate 342 be displaced in the vertical direction, but also it can be opened or closed to avoid the installation of the mounting plate 32 and the profiling block 31.

[0039] In a specific embodiment, a silica gel block is installed below the telescopic rod 343, and the silica gel block can prevent the structure to be processed from being damaged.

[0040] In the description of this specification, the description with reference to terms such as "one embodiment", "certain embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0041] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the claims and their equivalents.
