[0012] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0013] This embodiment discloses an automatic welding device for container door sealing plates, and its structure is as follows: Figure 1 and Figure 2 As shown, it is mainly composed of a workbench 8, a silo 2, a welding robot and a control console 12 for triggering control instructions. The workbench 8 includes a support frame and a horizontally arranged table top, and the table top is used to place the door vertical beam 6 and the door sealing plate 5. A welding robot and a control console 12 are arranged beside the workbench 8. The control console 12 is mainly used for command control of the entire device, and the welding robot is used to perform welding operations on the connection between the door vertical beam 6 and the door sealing plate 5.

[0014] by Figure 1 Taking the direction shown as an example, a tightening cylinder 10 and a clamping hand 11 are arranged on the left side of the table top of the workbench 8. The piston rod of the tightening cylinder 10 is arranged horizontally. The clamping hand 11 is used to clamp the door vertical beam placed on the table top. The clamping hand 11 is fixedly connected to the piston rod of the tightening cylinder 10. A guide wheel 9 is arranged on the top of the table top near the tightening cylinder 10. After the door vertical beam 6 is placed on the table top, the guide wheel 9 can guide and limit the side of the door vertical beam. The clamping hand 11 clamps the edge of the door vertical beam 6. Under the horizontal push of the piston rod of the tightening cylinder 10, the door vertical beam 6 can be pushed to the right until it collides with the door sealing plate 5 dropped on the right end of the table top and stops moving. The setting of the guide wheel 9 prevents the door vertical beam 6 from deflecting during the movement.

[0015] A silo 2 is provided on the right side of the table. The silo 2 is used to place multiple door sealing plates 5. A material discharge cylinder 3 and a material discharge head 1 are provided on the silo 2. A positioning cylinder 4 is provided at the lower part of the material discharge cylinder 3. The piston rods of the material discharge cylinder 3 and the positioning cylinder 4 are both arranged horizontally. A large number of door sealing plates 5 need to be stored in the silo 2. Each door sealing plate 5 can be stacked in a row longitudinally. In order to prevent the door sealing plates 5 in the silo 2 from accidentally falling, in this embodiment, a material discharge cylinder 3 is arranged horizontally on the silo 2, and a baffle is arranged on the side of the silo 2 opposite to the material discharge cylinder 3. The door sealing plates 5 in the silo 2 can be tightened by the cooperation of the piston rod of the material discharge cylinder 3 and the baffle. A discharge notch is provided on one side of the silo 2, and the discharge notch faces the table surface. The discharge head 1 can use a cylinder perpendicular to the discharge cylinder 3, and an additional lifting cylinder can be provided to drive the discharge head 1 to rise and fall. The discharge head 1 can be used to push one of the stacked door sealing plates 5 from the silo 2 onto the table surface. The door sealing plate 5 dropped onto the table surface can be fixed in position by the cooperation of the positioning cylinder 4 and other limit blocks.

[0016] Through the above structural design, the door vertical beam 6 and the door sealing plate 5 can be accurately positioned, and the welding position needs to be the joint between the door vertical beam 6 and the door sealing plate 5. Since the welding position is fixed, the welding robot in this embodiment does not need to move for operation, and can be directly fixed in one position using a six-axis joint robot 7. The six-axis joint robot 7 can realize multi-axis joint linkage, flexible position conversion, good controllability, and can realize accurate spot welding of the door sealing plate 5. Figure 1 and Figure 2 As shown, a base 14 is arranged beside the workbench 8, and the bottom of the six-axis articulated robot 7 is fixedly mounted on the base 14. A welding gun 13 is arranged on the top of the six-axis articulated robot 7, and the welding gun 13 is connected to an air pipe 15, which provides the welding gun 13 with a melting electrode gas.

[0017] The working process of the automatic welding device of the utility model is as follows:

[0018] Preparation work: manually put multiple door sealing plates 5 into the silo 2 to meet the welding of multiple door vertical beams 6; manually fix a door vertical beam 6 on the table surface of the workbench 8 through the guide wheel 9, and clamp the edge of the door vertical beam 6 with the clamp 11.

[0019] After completing the above preparations, first press the unloading start button on the interface of the control panel 12, the piston rod of the positioning cylinder 4 extends out to prepare, the unloading head 1 pushes a door sealing plate 5 in the silo 2 to fall from the silo 2, and the door sealing plate 5 falls to the table in front of the positioning cylinder 4, and the piston rod of the positioning cylinder 4 continues to extend to tighten the door sealing plate 5 to fix the position, and the unloading head 1 rises back to its position; then, the piston rod of the tightening cylinder 10 moves to the right, driving the clamp 11 to push the door vertical beam 6 toward the door sealing plate 5 until the door sealing plate 5 and the side of the door vertical beam 6 are close together. Then press the welding start button on the interface of the control panel 12 to drive the six-axis articulated robot 7 to weld the door sealing plate 5 to the door vertical beam 6. After the welding is completed, the six-axis articulated robot 7 is reset; after the welding is completed, the piston rod of the positioning cylinder 4 is away from the door sealing plate 5 to prepare for the next work; the piston rod of the tightening cylinder 10 retracts, driving the clamping hand 11 to pull the door vertical beam 6 with the door sealing plate 5 welded to the initial position, and then the clamping hand 11 is released; the door vertical beam 6 workpiece with the door sealing plate 5 welded is manually taken away, waiting for the next cycle.

[0020] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
