[0001] This invention relates to the field of conveyor technology, and more particularly to an intelligent conveyor line for automotive welding. Background Technology

[0002] Welding is a crucial step in automobile manufacturing. Patent document CN206915216U discloses an automobile welding production line, characterized by comprising a lifting roller bed, a fixed roller bed, a horizontal moving mechanism, and a trolley. The fixed roller bed, lifting roller bed, and horizontal moving mechanism are connected end-to-end in a rectangular layout, and the fixed roller bed, lifting roller bed, and horizontal moving mechanism drive the trolley to move. This utility model provides an automobile welding production line with high conveying speed, capable of simultaneously processing and conveying multiple vehicle models, and can also perform welding on difficult-to-weld areas such as body panels and roofs.

[0003] In practical use, it has been found that automotive welding conveyor lines typically have a low degree of automation and the position of the automotive parts to be welded is fixed when they are transported to the welding area. When the welding position of the automotive parts to be welded needs to be changed, it is not convenient to adjust the position of the automotive parts to be welded. Therefore, we propose an intelligent conveyor line for automotive welding to solve the above problems. Summary of the Invention

Chains are driven on the corresponding two sprockets. Multiple fixing plates are fixedly mounted on the chains. A connecting plate is fixedly mounted on the top of the fixing plates.

[0008] The bottom of the conveyor body is fixedly installed with multiple vertical rods, and the bottom of the multiple vertical rods is fixedly installed with the same horizontal plate. The top of the horizontal plate has two movable holes, and a movable seat is slidably installed in the movable holes. A fixed seat is fixedly installed on one side of the movable seat. Fixed grooves are opened on both sides of the connecting plate, and the fixed seat is adapted to the corresponding fixed groove.

[0009] The top of the adjustment plate has a rectangular hole, and a rectangular seat is slidably installed in the rectangular hole. The top of the rectangular seat is fixedly installed on the adjustment plate. The adjustment plate is provided with a drive mechanism, and the drive mechanism is connected to the rectangular seat. A frame is fixedly installed at the bottom of the rectangular seat, and a moving wheel is installed at the bottom of the frame.

[0010] Preferably, a support plate is fixedly installed between the two vertical rods, a hydraulic cylinder is fixedly installed on the top of the support plate, a push plate is fixedly installed on the output shaft of the hydraulic cylinder, and two hinge rods are hinged to the bottom of the push plate, with the bottom ends of the hinge rods hinged to the movable seat.

[0011] Preferably, each of the two rectangular seats has a slot on one side that is close to the other, and the movable seat is provided with an insertion mechanism that is adapted to the slot.

[0012] Preferably, the mating mechanism includes a sliding hole and a plug rod. The sliding hole is formed on the vertical rod, and the plug rod is slidably installed in the sliding hole. One end of the plug rod is fixedly installed on the movable seat, and the plug rod is adapted to the corresponding slot.

[0021] 2. By starting the drive motor, the drive motor can drive the rotating shaft and sprocket to rotate. The sprocket can drive the fixed plate and connecting plate to rotate through the chain. The connecting plate can drive the conveyor body to be conveyed on the conveyor frame, thereby conveying the automotive parts to be welded to the welding area.

[0022] 3. When the automotive parts to be welded are transported to the welding area, the rotating gear and the rack work together to drive the rectangular seat to move upward through the rack. The rectangular seat can drive the adjusting plate to move upward, and the adjusting plate can drive the automotive parts to be welded to move upward through the placement plate. This can achieve the purpose of moving the welding station of the parts to be welded and adjusting its height.

[0023] 4. When the adjusting plate moves upward, the locking rod separates from the locking slot, releasing the rack seat from its fixation. By activating hydraulic cylinder two, the hydraulic rod two drives the rack seat to move via the output shaft. The rack seat then drives the transmission shaft and the placement plate to rotate via the transmission gear, thereby achieving the purpose of adjusting the welding position of the automotive parts to be welded.
