[0002] Cabin doors, as the name implies, refer to the doors used in cabins. Cabin doors include airtight doors, non-airtight doors, and cold storage doors. Regardless of the type of cabin door, they need to be able to isolate wind and rain. Cabin doors are generally made of steel. During the production and processing of cabin doors, the steel plates are cut using a cutting device, and then the cut parts are polished and other operations are performed. Then all the accessories are welded together to form the entire cabin door. In this process, welding equipment is required. In the process of welding cabin doors, due to the large size of cabin doors, the accessories are generally placed on a bracket that can be transported, and a welding manipulator is used for welding.

DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0028] like Figure 1-Figure 7 As shown, a welding device for the production and processing of cabin doors includes a bracket 1 and a manipulator 7. A conveying roller 2 is provided on the bracket 1, and a rotating shaft 3 is provided at the end of the conveying roller 2, and the rotating shaft 3 is connected to the bracket 1. A leg 4 is fixedly installed on the bracket 1, a cleaning structure 5 is installed on the leg 4, a cleaning frame 6 is installed on the rotating shaft 3, and the cleaning frame 6 contacts the cleaning structure 5. The lower end of the leg 4 is connected with an adjusting structure 8. A rotating seat 9 is provided at the lower end of the manipulator 7, and the rotating seat 9 is fixedly installed on the adjusting structure 8. The connection between the bracket 1 and the leg 4 is welding, and a cross bar is provided between the legs 4. The conveying roller 2 is installed on the bracket 1 through the rotating shaft 3, a motor 10 is fixedly installed on the bracket 1, and the motor 10 is connected to the rotating shaft 3 at the end of the conveying roller 2. A welding head 11 is provided at the end of the manipulator 7, and the welding head 11 is located above the conveying roller 2. The rotating shaft 3 at one end of the conveying roller 2 passes through the bracket 1, and a sprocket chain assembly is provided at the end of the rotating shaft 3.

[0029] When the device is used for welding the cabin door, the bracket 1 is firmly placed on the ground through the legs 4, and an adjustment structure 8 is connected to the lower end of the legs 4. A rotating seat 9 with a manipulator 7 is installed on the adjustment structure 8, and then a cleaning structure 5 is installed on the legs 4, and a cleaning frame 6 is installed at a corresponding position on the rotating shaft 3. After the cleaning frame 6 and the cleaning structure 5 are installed, the welding work is started after connecting the power supply and other structures. During welding, the workpiece to be welded is placed on the conveying roller 2 between the brackets 1, and spot welding is performed between the corresponding structures of the workpiece to ensure that the workpiece The two conveyors 10 are pre-fixed together, and then a command is sent through the control box. The motor 10 on the bracket 1 starts to run with the first conveyor roller 2. The first conveyor roller 2 rotates, thereby driving the sprocket chain assembly at the end of the rotating shaft 3 to run. Driven by the chain sprocket assembly, the remaining conveyor rollers 2 rotate synchronously, thereby moving the pre-welded workpiece, and stopping when the workpiece moves to a suitable position. Then the manipulator 7 starts to move the welding head 11 close to the position where welding is required. When the welding head 11 contacts the part where welding is required, welding work on the workpiece begins. In this process, the conveyor roller 2 does not run to ensure the stability of the workpiece. At the same time, the manipulator 7 moves flexibly with the welding head 11 to ensure welding flexibility. When the welding work is completed, the conveyor roller 2 runs to move the cabin door after welding to the next station, and at the same time, it moves the next workpiece to be welded to the welding position for welding. After sending away the welded cabin door, there is a blank period without workpieces on the conveyor roller 2 under program control. During the blank period, the cleaning structure 5 starts to run, and the corresponding structure in the cleaning structure 5 moves from one end of the conveyor roller 2 to the other. One end moves, thereby scraping the surface of the conveyor roller 2, cleaning the welding slag generated during welding from the conveyor roller 2, ensuring the cleanliness of the surface of the conveyor roller 2, and then ensuring the stable placement and smooth transportation of subsequent workpieces, ensuring the use effect, with the resetting of the cleaning structure 5, the cleaning frame 6 will clean the corresponding structure in the cleaning structure 5, thereby ensuring the normal use of the cleaning structure 5, the structure is simple, the use is convenient and fast, the effect is excellent, when necessary, the adjustment structure 8 can also be used to adjust the position of the rotating seat 9, thereby changing the action of the manipulator 7 and improving the flexibility of use.

[0030] like Figure 3 , Figure 4As shown, the cleaning structure 5 includes a fixed plate 501, a guide column 502, a movable plate 503 and a scraper frame 506, the fixed plate 501 is fixedly mounted on the support legs 4, the guide column 502 is arranged between the fixed plates 501, the movable plate 503 is movably mounted on the guide column 502, the scraper frame 506 is fixedly mounted on the movable plate 503, and the scraper frame 506 is sleeved on the rotating shaft 3, the cleaning structure 5 also includes a servo motor 504, a screw rod 505 and a protective cover 507, the servo motor 504 is fixedly mounted on the fixed plate 501, the screw rod 505 is arranged between the fixed plates 501, and the screw rod 505 is connected to the servo motor 504, the screw rod 505 runs through the movable plate 503, and the screw rod 505 and the movable plate 503 are threadedly connected, the scraper frame 506 is in contact with the cleaning frame 6, the protective cover 507 is installed on the fixed plate 501, and the protective cover 507 is fixedly connected to the fixed plate 501 The protective cover 507 is located above the screw rod 505, and the protective cover 507 passes through the gap between the scraper frame 506.
