Description

Technical Field

[0001] This invention relates to the field of automotive parts welding technology, specifically to an automated welding device for automotive seat parts. Background Technology

[0002] In the manufacturing process of automobile seats, the seat frame typically involves the stacking and welding of multiple layers of metal sheets. Components such as the seat back support plate and connecting brackets are formed by welding upper and lower metal sheets after they are positioned and stacked. The structural characteristics of the upper and lower metal sheets in an automobile seat frame often differ, for example... Figure 11 and Figure 12 As shown, the upper metal plate has a circular mounting hole and the lower metal plate has an arc-shaped elongated hole. When the two are stacked, they not only need to be aligned at the center, but also need to ensure the uniqueness of the angle direction. Otherwise, the assembly dimensions of the product will be out of tolerance after welding.

[0003] Chinese patent CN218016354U discloses a hydraulic resistance welding device, including a frame; a first hydraulic cylinder disposed on one side of the frame; a second hydraulic cylinder located on the other side of the frame and working synchronously with the first hydraulic cylinder, its output end being opposite to the output end of the first hydraulic cylinder; a first electrode assembly connected to the output end of the first hydraulic cylinder; a second electrode assembly connected to the output end of the second hydraulic cylinder, and the second electrode assembly cooperating with the first electrode assembly; and a hydraulic pump station connected to the first hydraulic cylinder and the second hydraulic cylinder. However, this device still has the following problems during use: The upper and lower metal plates are placed directly between the first and second hydraulic cylinders for welding without a corresponding positioning device, which cannot ensure that the upper and lower metal plates are aligned in the center. During the pressure welding process, the stacked upper and lower metal plates are also prone to shifting, affecting the stability of the welding current distribution, and thus causing inconsistent weld penetration or spatter defects.

[0007] Compared with the prior art, the beneficial effects of this invention are as follows: 1. The vibrating screen feeders of the first and second material distribution components control the upper and lower metal plates to move continuously to the position of the lifting and transferring component. Then, the lifting and transferring component first distributes the upper and lower metal plates one by one, and then lifts the upper and lower metal plates upward so that the upper and lower metal plates are aligned with the first and second material handling components respectively. The first and second material handling components respectively adsorb and fix the upper and lower metal plates. Then, the second material handling component first controls the lower metal plate to move above the lower electrode component and places the lower metal plate on the lower electrode component. Then, the positioning component limits the arc-shaped mounting hole of the lower metal plate to prevent the lower metal plate from deflecting and ensures the accuracy of subsequent welding of the upper and lower metal plates. 2. While the second conveying component resets and conveys the next lower metal plate from the second material distribution component, the first conveying component moves the upper metal plate to the right above the lower electrode component. The circular mounting hole of the upper metal plate is then placed downwards along the positioning component on top of the lower metal plate, aligning the welding holes in the middle of the upper and lower metal plates. Subsequently, the first conveying component moves to the left to ensure that the upper electrode component can move downwards until it contacts the welding hole. Then, the upper and lower electrode components cooperate to weld and fix the upper and lower metal plates. This achieves alternating parallel operation of loading, unloading, and stacking processes, reducing welding waiting time and further improving overall welding efficiency. 3. The positioning component releases the restriction on the lower metal plate, and the first conveying component moves back above the lower electrode component, fixing the welded product composed of the upper and lower metal plates and removing it from the lower electrode component. Then, the pushing component controls the first conveying component to move forward until the welded product is aligned with the receiving component. The first conveying component then releases the fixation on the welded product, allowing it to move into the receiving component for automatic unloading. The above operation is then repeated to achieve automatic batch stacking welding of the upper and lower metal plates without manual intervention, effectively improving the automation level and material supply efficiency of the welding operation.

In this invention, the vibrating screen feeder 32 of the first and second material distribution components respectively controls the upper metal plate 6 and the lower metal plate 7 to continuously move to the position of the lifting and transferring component. Then, the lifting and transferring component first distributes the upper metal plate 6 and the lower metal plate 7 one by one, and then lifts the upper metal plate 6 and the lower metal plate 7 upward, so that the upper metal plate 6 and the lower metal plate 7 are aligned with the first and second material handling components respectively.

The upright plate 38 is fixedly installed on the right side of the support bracket 33; the lifting dual-shaft push cylinder 39 is fixedly installed on the front end of the upright plate 38; the lifting push plate 310 is fixedly connected to the output end of the lifting dual-shaft push cylinder 39. The upper end of the lifting push plate 310 of the second material distribution component is fixedly installed with a contoured insert 311 that is inserted into the arc-shaped mounting hole 71. like Figures 1-10 As shown, both the first and second transport components include a support frame 41, a linear module 42, a material transfer dual-axis push cylinder 43, an L-shaped moving plate 44, a limiting plate 45, a limiting post 46, and a vacuum suction cup 47.

A vacuum suction cup 47 is also fixedly installed at the lower end of the limiting plate 45; the vacuum suction cup 47 is connected to an external air pump. In this invention, the vibrating screen feeders 32 of the first and second material distribution components control the upper metal plate 6 and the lower metal plate 7 to move continuously to the position of the rear feed inlet 341. When the upper metal plate 6 or the lower metal plate 7 moves into the limiting slot 37, the push rodless cylinder 35 controls the transverse push plate 36 to move along the push port 342 to the position of the lifting port 343. Then, the lifting dual-shaft push cylinder 39 controls the lifting push plate 310 to move upward. The lifting push plate 310 of the first material distribution component drives the upper metal plate 6 to rise until the upper metal plate 6 is aligned with the limiting post 46 on the limiting plate 45 of the first conveying component. Then, the vacuum suction cup 47 of the first conveying component adsorbs and fixes the upper metal plate 6. The contoured insert 311 on the lifting push plate 310 of the second material distribution component will align with the arc-shaped mounting hole 71, and control the lower metal plate 7 to rise upward, so that the lower metal plate 7 is aligned with the limiting post 46 on the limiting plate 45 of the second conveying component.

Subsequently, while the linear module 42 of the second transport component drives the material transfer dual-axis push cylinder 43 to reset to the right to transport the next lower metal plate 7, the linear module 42 of the first transport component will drive the material transfer dual-axis push cylinder 43 to move to the right, so that the upper metal plate 6 moves above the lower mounting platform 25. Then, the material transfer dual-axis push cylinder 43 of the first transport component controls the upper metal plate 6 to move down, so that the circular mounting hole 61 of the upper metal plate 6 is stacked down along the positioning post 210 on the upper end of the lower metal plate 7, and at this time the welding hole 8 opened in the middle of the upper metal plate 6 and the lower metal plate 7 are aligned. Subsequently, the linear module 42 of the first conveying component controls the material transfer dual-axis push cylinder 43 to move to the left, ensuring that the welding cylinder slide module 22 can control the upper electrode rod 23 and the upper electrode head 24 to move downward until the upper electrode head 24 contacts the welding hole 8. Then, the external power supply passes a large current to the location through the upper electrode rod 23 and the lower electrode rod 26, causing the contact position of the upper metal plate 6 and the lower metal plate 7 to heat up and melt, thereby achieving the welding and fixing of the upper metal plate 6 and the lower metal plate 7. Then, the limiting cylinder 28 controls the contour limiting rod 29 to reset, releasing the limit on the lower metal plate 7. The first conveying component re-controls the linear module 42 to move the material transfer dual-axis push cylinder 43 above the lower mounting platform 25, so that the vacuum suction cup 47 of the first conveying component adsorbs and fixes the welded product composed of the upper metal plate 6 and the lower metal plate 7, and moves it out of the lower mounting platform 25. Then, the pushing component controls the support frame 41 of the first conveying component to move forward until the welded product is aligned with the receiving component. The vacuum suction cup 47 of the first conveying component releases the fixation on the welded product, so that the welded product moves into the receiving component to achieve automatic unloading. By repeating the above operations, the automatic batch stacking and welding of the upper metal plate 6 and the lower metal plate 7 can be achieved.
