[0020] (III) Beneficial effects

[0021] The beneficial effects of the present invention are as follows: By adopting the above technical solution, the plane length, width dimensions and diagonal dimensions of the entire side plate after assembly are the same as those of the inner frame, thereby accelerating the overall assembly speed of the side plates, shortening the utilization time of the overall assembly platform, increasing the output, improving the efficiency, and making the gap between the side plate and the skeleton square controllable, improving the versatility and convenience of robot welding, increasing the robot welding speed and weld quality, reducing the number of robot shutdowns, and greatly reducing the manual repair welding working hours. Description of the drawings

[0022] Figure 1 It is a schematic diagram of the splicing and welding structure of the side plate. Detailed implementation manners

[0023] In order to better explain the present invention for easy understanding, the present invention will be described in detail below with reference to the drawings through specific implementation manners.

[0024] Please refer to Figure 1 , the present invention provides a manufacturing process for handling, assembling and welding the side plates of a container, including the following steps:

[0025] S1: Perform side plate cutting so that the length and width of the side plate are each 10 mm larger than the designed dimensions. After a single side plate is roll-formed, there are 10-mm reserved cutting edges for both the length and width of the side plate;

[0026] S2: Stack single side plates one by one using a lifting device:

[0027] S3: Transfer the stacked side plates to a special bracket beside the workbench. Use a lifting device to move the first side plate from the bracket to the workbench, and align the side plate with the reference edge of the platform, making the side plate in close contact with the workbench to ensure the side plate is flat.

[0028] S4: Use a laser cutting machine to cut a 5 - mm length on one short side and two adjacent long sides of the first side plate near the reference edge, ensuring that the cut short side of the side plate is perpendicular to the two adjacent long sides, and ensuring that the width of the side plate is the same as the designed width.

[0029] S5: Move the cut side plate to the assembling area on the workbench.

[0030] S6: Repeat steps S4 and S5. Transfer the second and third side plates to the workbench, fix and cut them, and then transfer them to the assembling area using a roller conveyor.

[0031] S7: After aligning the two assembling seams of the three plates, use a multi - point electromagnet to adsorb the three side plates on the integrated workbench at the same time, and use a double - gun laser welder to weld the butt joints to complete the splicing of the small - unit side plates.

[0032] S8: Repeat steps S6 and S7. Transfer the fourth and fifth side plates, fix and cut them, and then transfer them to the assembling area using a roller conveyor. After aligning the assembling seams, weld them.

[0033] S9: Repeat S8 to assemble and weld the remaining side plates in sequence to complete the overall assembly of the side plates.

[0034] S10: After the overall assembly of the side plates is completed and the welding shrinkage deformation ends, when the size of the assembled side plates is stable, adsorb and fix them on the cutting table, and then use a laser cutting machine to cut the four - side contour lines of the whole side plate to the designed size, so that the errors of the plane size and diagonal size of the whole assembled side plate are within the standard range.

[0035] In step S3, a number of electromagnetic suction blocks are arranged on the workbench, and the side plate is in close contact with the workbench through the electromagnetic suction blocks.

[0036] In step S2, a number of electromagnetic suction blocks are arranged at the bottom of the lifting device.

[0037] Using the mechanical assembly principle, that is, each component is precisely manufactured according to the tolerance fit, and the electromagnetic electromagnet is reasonably and skillfully used to carry and fix the side plate. By making full use of the existing mature laser cutting and laser welding technologies, a new manufacturing process for the blanking, handling, assembly and welding of the container side plate is invented. After the whole side plate is assembled, the plane length, width and diagonal dimensions are the same as those of the inner frame, thus accelerating the total assembly speed of the side plate, shortening the utilization time of the total assembly platform, increasing the output, improving the efficiency, and making the gap between the side plate and the skeleton square controllable, improving the versatility and convenience of robot welding, increasing the robot welding speed and weld quality, reducing the robot downtime, and greatly reducing the manual repair welding man-hours.

[0038] Use a moving sling. Two groups of moving slings are set (it can also be three groups or four groups according to the side plate length). Multiple-point electromagnetic electromagnets are arranged at the bottom of the moving sling. The adsorption surface is consistent with the side plate waveform to ensure that the side plate is always tightly adsorbed on the electromagnetic electromagnet. The electromagnetic electromagnet is connected to the vertical lifting guide column. The guide column accurately controls the lifting displacement through a servo motor. The guide column is connected to the transverse moving seat. The transverse moving seat is driven by a servo motor to drive the guide column to move horizontally, realizing the horizontal adjustment and alignment adsorption. The horizontal degree and vertical degree of each group of electromagnetic electromagnets are monitored in real time through sensors to ensure that each group of electromagnets is always on the same horizontal plane, realizing the hoisting and moving of the side plate in a horizontal state all the time. Then set up a support cross beam to strengthen the horizontal stiffness of each group of electromagnetic electromagnets. The whole sling system is installed on the moving gantry, and through the special ground rail, the adsorption and moving position of the side plate can be controlled, and it is ensured that there is no deformation during the handling process.
