[0011] Beneficial effects

[0012] This utility model provides a plate welding device, which has the following beneficial effects:

[0013] 1. By opening cavities, grooves, and ventilation ducts, and installing an exhaust fan, after placing the plate on the workbench, turning on the exhaust fan can extract the gas in the cavities, grooves, and ventilation ducts until a vacuum is reached, thereby fixing the plate.

After the board is placed, the lifting block 6 can be lowered under the action of the board's own weight. At this time, the spring 7 is compressed, and the ventilation duct 5 is connected to the groove 4 and the cavity 2 to facilitate the fixing of the board.

[0025] Specifically, a movable plate 13 is movably installed inside the cavity 2, a pair of first cylinders 12 are fixedly installed at the bottom of the worktable 1, the telescopic ends of the pair of first cylinders 12 are fixedly connected to the movable plate 13, several connecting rods are fixedly installed on the movable plate 13, several sliding grooves 9 are opened inside the worktable 1, ball seats 10 are slidably installed in the several sliding grooves 9, the several ball seats 10 are all fixedly connected to the several connecting rods, and ball bearings 11 are rotatably installed in the several ball seats 10.

[0033] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical connections between the various electrical components are completed in sequence. The detailed connection methods are well-known technologies in the field. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0034] The working principle and usage process of this utility model are as follows: When in use, the sheet material is placed on the workbench 1. To move the sheet material 13, the first cylinder 12 is activated. The extension end of the first cylinder 12 extends, causing several connecting rods, ball seats 10, and rollers 11 to rise until the rollers 11 contact the sheet material and the sheet material leaves the top of the lifting block 6. The sheet material 13 can then be easily moved. After adjusting the position of the sheet material, the extension end of the first cylinder 12 retracts, causing the moving sheet material 13 to descend, thereby causing the ball seats 10 and rollers 11 to descend until the rollers 11 no longer contact the sheet material. At this point, the sheet material is in good condition. Under the action of force, the lifting block 6 can be lowered. At this time, the spring 7 is compressed, and the groove 4, ventilation duct 5 and cavity 2 are connected. The exhaust fan 3 is turned on, and the groove 4, ventilation duct 5 and cavity 2 can be drawn into a vacuum state. At this time, the plate can be fixed on the worktable 1. The second cylinder 14 is started. The extension end of the second cylinder 14 extends and drives the mounting cover 15 to fall, thereby driving the welding gun 18 to fall until it is convenient to weld the plate. The motor is started to drive the threaded rod 16 to rotate, thereby driving the slider 17 to move, thereby driving the welding gun 18 to move, which is convenient to weld the entire gap of the plate.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
