[0014] 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.

[0015] This embodiment discloses an automatic welding device for a wide side reinforcement plate on a wide bottom beam of a container, and its structure is as follows: Figure 1 and Figure 2 As shown, it is mainly composed of a large silo 1, a small silo lifting cylinder 2, a large silo feeding head 3, a large silo feeding cylinder 4, a small silo feeding cylinder 5, a small silo feeding head 6, a small silo 7, a welding robot, a workbench 10, and a control console 13. The workbench 10 includes a support frame and a table for placing a wide bottom beam 11, and a fixing device is provided on the table to fix the position of the wide bottom beam 11. The control console 13 is located on the side of the workbench 10 and is mainly used for command control of the entire device. A small silo 7 and a large silo 1 are respectively provided above the workbench 10. The small silo 7 is located below the large silo 1. The large silo 1 is used to place a large number of wide-edge reinforcement plates 12, and the large silo feeding head 3 delivers a wide-edge reinforcement plate 12 to the small silo 7 each time. The small silo 7 is only used to store one wide-edge reinforcement plate 12. The small silo 7 moves up and down, and the wide-edge reinforcement plate 12 is placed on the wide bottom beam 11 through the small silo feeding head 6. An automatic welding robot is also provided beside the workbench 10 , which can realize automatic welding operations on the wide side reinforcement plate 12 placed on the wide bottom beam 11 .

[0016] To further explain, since the position on the wide bottom beam 11 where the wide side reinforcement plate 12 needs to be welded is fixed, it is only necessary to fix the wide bottom beam 11 where it needs to be welded on the table top of the workbench 10, and the position where the wide side reinforcement plate 12 is placed on the wide bottom beam 11 by the small silo 7 is also fixed. Therefore, the welding robot in this embodiment does not need to move for operation, and can be directly fixed in one position using the six-axis articulated robot 9. The six-axis articulated robot 9 can realize multi-axis joint linkage, flexible position conversion, good controllability, and can realize precise spot welding of the wide side reinforcement plate 12. Figure 1 and Figure 2 As shown, a base 15 is arranged beside the workbench 10 , and the six-axis articulated robot 9 is fixedly mounted on the base 15 . A welding gun 14 is arranged on the top of the six-axis articulated robot 9 . The welding gun 14 is connected to an air pipe 16 , and the air pipe 16 provides the welding gun 14 with a melting electrode gas.

[0017] The feeding mechanism of the large silo 1 is further explained. A large number of wide-side reinforcing plates 12 need to be stored in the large silo 1. The wide-side reinforcing plates 12 can be stacked vertically in a row. In order to prevent the wide-side reinforcing plates 12 in the large silo 1 from accidentally falling off, in this embodiment, a large silo top-loading cylinder 4 is also arranged in the horizontal direction on the large silo 1, and a baffle is arranged on the opposite side of the large silo 1 and the large silo top-loading cylinder 4. The wide-side reinforcing plates 12 in the large silo 1 can be tightened by utilizing the cooperation of the piston rod of the large silo top-loading cylinder 4 and the baffle. A discharge notch is provided on one side of the large silo 1, and the discharge notch faces the side where the small silo 7 is located. The small silo 7 and the large silo 1 are somewhat staggered in upper and lower positions. The large silo discharge head 3 can also use a cylinder, and an additional large silo lifting cylinder can be provided to drive the large silo discharge head 3 to rise and fall. The large silo discharge head 3 and the large silo top cylinder 4 are arranged in a vertical direction. The large silo discharge head 3 can push one of the stacked wide-edge reinforcement plates 12 from the large silo 1 into the small silo 7.

[0018] Further explanation of the feeding mechanism of the small silo 7 is that a small silo top-loading cylinder 5 is also provided in the horizontal direction on the small silo 7. The function of the small silo top-loading cylinder 5 is similar to that of the large silo top-loading cylinder 4, both of which are to support the wide-side reinforcement plate 12 to prevent it from accidentally falling. The small silo 7 is fixedly installed on the small silo lifting cylinder 2. When the small silo 7 needs to receive the wide-side reinforcement plate 12 from the large silo 1, the small silo 7 is located at the highest position of the small silo lifting cylinder 2 to reduce the risk of the wide-side reinforcement plate 12 accidentally falling. When the wide-side reinforcement plate 12 falls into the small silo 7, the small silo lifting cylinder 2 drives the small silo 7 to descend to the lowest position, and the wide-side reinforcement plate 12 in the small silo 7 is pushed out by the small silo unloading head 6, and placed at the welding position on the wide bottom beam 11. The small silo unloading head 6 can also press the wide-side reinforcement plate 12 placed on the wide bottom beam 11 to ensure that the welding position is fixed. The specific design of the various driving mechanical structures involved above, after the execution functions of each main driving mechanism have been given above, can be fully realized based on existing mechanical design technology for those skilled in the art.

[0019] As an automatic welding equipment, the design process tries to reduce manual participation and improve the degree of automation. The utility model sets sensors to collect signals for the control chip in the control console 13. The control chip sends work instructions to each device according to the received sensor signals. Two control schemes are provided below:

[0020] Solution 1: Two command buttons are set on the operation interface of the control panel 13, namely the unloading command button and the welding command button, and a sensor 8 is also installed under the small silo 7. The sensor 8 in this solution adopts a position sensor, which can obtain the position of the small silo 7 in real time. For example, a laser ranging sensor can be used to measure the distance between the small silo 7 and the surface of the workbench 10 in real time, and compare it with the preset distance threshold in the control system. When the set distance threshold position is reached, it means that the small silo 7 has dropped to the specified height. The specific control process of this scheme is: first, manually place the required number of wide-edge reinforcement plates 12 in the large silo 1, and fix the wide bottom beam 11 to the table top of the workbench 10. After completing the above preparations, the operator presses the unloading command button, and the wide-edge reinforcement plate 12 can automatically complete the entire unloading process, that is, the large silo unloading head 3 pushes the single wide-edge reinforcement plate 12 into the small silo 7, and then the large silo unloading head 3 returns to its position, and the small silo lifting cylinder 2 drives the small silo 7 to descend to the preset position. When the control chip determines that the small silo 7 has been loaded according to the feedback signal from the received position sensor, the control chip will automatically unload the small silo 7. After it is in place, control instructions are automatically sent to the small material bin top cylinder 5 and the small material bin unloading head 6 in turn, and the small material bin unloading head 6 pushes the wide side reinforcement plate 12 onto the wide bottom beam 11 and presses it down. At this time, the entire unloading process is completed; then, the welding instruction button is pressed manually, and the control chip of the control console 13 will send a work instruction to the six-axis articulated robot 9, and the six-axis articulated robot 9 will automatically complete the welding operation. After welding is completed, the welding gun 14 is reset through the movement of the joint, the small material bin unloading head 6 returns to its position, and the small material bin lifting cylinder 2 rises to drive the small material bin 7 back to its position, and waits for the next cycle operation again.

[0021] Solution 2: The main difference between this solution and Solution 1 is that only one command button, namely the start button, is required on the operation interface of the control panel 13, and the sensor 8 on the side of the workbench 10 is replaced with an infrared sensor. The sensor here is no longer used to detect the descending height of the small silo 7, but is used to detect whether there is a wide-edge reinforcement plate 12 on the top of the wide bottom beam 11. The specific control process of this solution is: first, manually place the required number of wide-edge reinforcement plates 12 in the large silo 1, and also fix the wide bottom beam 11 to the table surface of the workbench 10. After completing the above preparations, the operator presses the start button, and the unloading and welding of the wide-edge reinforcement plate 12 can be automatically completed, that is: the large silo unloading head 3 pushes the single wide-edge reinforcement plate 12 into the small silo 7, and then the large silo unloading head 3 returns to its position, and the small silo lifting cylinder 2 drives the small silo 7 to descend to the specified position. The specified position can be achieved by setting the stroke of the small silo lifting cylinder 2, which can save the method of using sensors to collect signals; when the small silo 7 has been lowered into place After that, the small material bin top cylinder 5 and the small material bin unloading head 6 are started successively, and the small material bin unloading head 6 pushes the wide side reinforcement plate 12 onto the wide bottom beam 11 and presses it down; the infrared sensor will detect in real time whether the wide side reinforcement plate 12 has been placed on the top of the wide bottom beam 11. Once it is detected that it has been placed, it will feedback a signal to the control chip of the control console 13. The control chip will automatically send a work instruction to the six-axis articulated robot 9, and the six-axis articulated robot 9 will automatically complete the welding operation. After welding is completed, the welding gun 14 is reset by the joint movement, the small material bin unloading head 6 returns to its position, and the small material bin lifting cylinder 2 rises to drive the small material bin 7 back to its position, and wait for the next cycle operation again.

[0022] 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.
