The A-pillar inner panel reinforcement plate is an important component to enhance the performance of the A-pillar, and the optimization of its manufacturing process is crucial to improving the overall vehicle quality and production efficiency.

[0003] The existing manufacturing and welding of A-pillar inner panel reinforcement plates usually involves manually placing the inner panel and reinforcement plate onto the welding equipment. After the welding equipment is operational, the welding torch moves to perform the welding. After welding, the plates are manually removed and new plates are placed for the next round of welding. This operation is cumbersome, time-consuming, and requires frequent machine stops for loading and unloading. It is difficult to achieve continuous production, which leads to extended production cycles, affects production efficiency and quality, and increases production costs.

[0004] Therefore, it is necessary to design an A-pillar inner panel reinforcement plate manufacturing device that can automatically transport the inner panel and reinforcement plate for positioning and welding, while the extrusion limiting frame moves to facilitate the discharge of the welded plate, save time, reduce manual intervention, facilitate continuous production, and improve production efficiency and quality.

The output shaft of each first motor is connected to a fixing plate, and each fixing plate is rotatably connected to the adjacent connecting plate.

[0009] As a further preferred option, the fixing plate is made of rubber.

[0010] As a further preferred embodiment, the welding assembly includes an extrusion rod, a moving frame, a second motor, a guide rod, a lead screw, a second laser welding gun, and a positioning rod.

The front of the support frame 1 is provided with a positioning component for positioning the inner plate and the reinforcing plate. The upper sides of both the left and right sides of the support frame 1 are provided with fixing components for fixing the inner plate and the reinforcing plate. The upper part of the support frame 1 is provided with a welding component for welding the inner plate and the reinforcing plate.

[0022] like Figure 1 and Figure 3 As shown, the positioning component includes a connecting block 3, a limiting frame 301, and a spring 303. The upper front part of the support frame 1 is connected to two connecting blocks 3, one on the left and one on the right. The limiting frame 301 is connected to the connecting block 3 by a damping sliding mechanism. The spring 303 is connected between the limiting frame 301 and the connecting block 3 on the same side.

[0023] like Figure 1 and Figure 4 As shown, the fixing assembly includes a fixing plate 4, a first motor 401, and a connecting plate 402. The upper sides of both the left and right sides of the support frame 1 are connected to two connecting plates 402, and the upper part of each connecting plate 402 is connected to the first motor 401. The first motor 401 and the processor are electrically connected through a control module. The output shaft of each first motor 401 is connected to the fixing plate 4. Each fixing plate 4 is rotatably connected to the adjacent connecting plate 402. The fixing plate 4 is made of rubber, which has good wear resistance and is not easy to scratch the workpiece.

[0024] like Figure 1 , Figure 3 and Figure 5 As shown, the welding assembly includes an extrusion rod 302, a movable frame 5, a second motor 501, a guide rod 502, a lead screw 503, a second laser welding gun 504, and a positioning rod 505. The movable frame 5 is slidably connected to the upper part of the support frame 1. Two extrusion rods 302 are connected to the lower front side of the movable frame 5. Each extrusion rod 302 contacts the limiting frame 301 on the same side. The lower part of each extrusion rod 302 is spherical to facilitate extrusion. The second motor 501 is connected to the upper side of the support frame 1. The second motor 501 and the processor are electrically connected through a control module. The upper sides of both the front and rear parts of the support frame 1 are connected to two guide rods 502, which are slidably connected to the movable frame 5. The output shaft of the second motor 501 is connected to the lead screw 503, and the movable frame 5 is connected to the lead screw 503 by a thread. The lower side of the middle part of the movable frame 5 has six second laser welding guns 504, and the lower sides of both the front and rear parts of the movable frame 5 are connected to two positioning rods 505.

[0025] When laser welding technology is required to manufacture the A-pillar inner panel reinforcement plate, this device can be used. The support frame 1 is brought into contact with the ground, and then the A-pillar inner panel and reinforcement plate are stacked on the conveyor belt 101. The processor then starts the conveyor belt 101 via the control module to transport the A-pillar inner panel and reinforcement plate, allowing them to contact the limiting frame 301 for positioning. The processor then continues to place the inner panel and reinforcement plate. Next, the processor starts the first motor 401 via the control module, which drives the fixing plate 4 to rotate along the connecting plate 402 to contact and fix the plate. The first motor 401 is then turned off. The fixing plate 4 is... Made of rubber, it has good wear resistance and is not easily scratched on the workpiece, thus enabling it to fix the inner plate and reinforcing plate during welding, preventing displacement of the inner plate and reinforcing plate, and improving welding stability and efficiency. Then, the processor starts the second motor 501 through the control module, which drives the lead screw 503 to rotate. Under the action of the thread, the moving frame 5 moves along the guide rod 502, causing the second laser welding gun 504 to move, causing the positioning rod 505 to move and contact the plate for positioning and fixation, causing the pressing rod 302 to move and press the limiting frame 301 to move along the connecting block 3 and disengage from the plate, compressing the spring 303, and then shutting off the second motor 501. The lower part of each extrusion rod 302 is spherical for easy extrusion. Then, the second laser welding gun 504 is activated to perform laser welding on the plate. After welding, the second laser welding gun 504 is turned off. The processor, through the control module, activates the electric push rod 2 on one side, which drives the first laser welding gun 201 on that side to move and contact the plate. The first laser welding gun 201 is then activated again for welding and turned off. Next, the electric push rod 2 on one side reverses its operation, causing the first laser welding gun 201 on that side to move in the opposite direction and reset. The above operation is repeated using the first laser welding gun 201 on the other side. After welding is completed, the first motor 401 reverses its operation, causing the fixed plate 4... The rotation is reversed to reset, and then the second motor 501 operates in the reverse direction, causing the lead screw 503 to rotate in the reverse direction. Under the action of the thread, the moving frame 5 moves in the reverse direction, causing the second laser welding gun 504 to move in the reverse direction and reset. This causes the positioning rod 505 to move in the reverse direction and disengage from the plate, and the pressing rod 302 to move in the reverse direction and disengage from the limiting frame 301. The spring 303 rebounds, and under the action of damping, the limiting frame 301 slowly moves to reset. At the same time, the conveyor belt 101 continues to transport the plate, outputting the welded plate, so that the next plate moves and contacts the limiting frame 301. The above operation is repeated to continue positioning, fixing and welding the plate until the plate welding is completed.This allows for the automatic conveying of the inner plate and reinforcing plate for positioning and welding, while simultaneously pressing the limiting frame 301 to facilitate the discharge of the welded plate, saving time, reducing manual intervention, promoting continuous production, and improving production efficiency and quality. Then, the conveyor belt 101, the electric push rod 2, the first motor 401, and the second motor 501 can be shut down.
