Description

Technical Field

[0001] This invention relates to the field of industrial robot welding, and more particularly to a full-function column welding production line. Background Technology

[0002] Welding, also known as fusion welding, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure.

[0003] In existing industries, this process is mostly implemented through a fully manual mode or a combination of manual labor and individual workstations. The positioning of products in the welding process still relies on auxiliary tooling for positioning and manual spot welding for shaping.

[0004] In the manual mode, the parts are shaped manually using tooling or fixtures, then spot-welded to fix them in sequence. The entire welding process is carried out manually according to the process and manufacturing requirements until the parts are welded.

[0005] The manual and individual workstation modes are similar to the manual mode. In the early stage, the parts are shaped by manual tooling or fixtures and then fixed by spot welding. The purpose is to effectively connect the parts in the initial stage by spot welding. After that, the parts are transported to the fixed welding workstation by heavy cranes or transport racks for large-scale welding work.

[0006] The main reasons for this phenomenon are the changes in the material form of components such as columns and the shrinkage and deformation during the welding process. This results in traditional methods being unable to effectively supply component materials, assemble and weld parts, perform full welding throughout the entire process, finish finished products, and produce compatible products of different grades on the same production line.

[0007] Therefore, it is necessary to provide a fully functional column welding production line to solve the above-mentioned technical problems. Summary of the Invention

[0008] This invention provides a full-function welding production line for columns, which solves the problem that the current phenomenon is mainly limited by the changes in the material form of components such as columns and the shrinkage and deformation during the welding process, which makes it impossible for traditional methods to effectively supply component materials, assemble and weld parts, perform full welding throughout the entire process, finish the finished product, and produce compatible products of different grades on the same line.

This production line eliminates the need for human intervention during actual production; only equipment maintenance and upkeep personnel are required, significantly reducing the occurrence of such hazards.

[0064] Appendix Figure 1 The base plate welding module has been separated, which greatly optimizes the scalability of the entire production line.

[0066] The magazine feeding mechanism has been simplified, making it easier to change part numbers and feed materials more quickly.

[0067] The magazine feeding mechanism has been optimized for faster part number changes and feeding.

[0068] Add a small component welding module to more specifically weld the components on all four sides of the lift column.

[0069] The small component welding module includes a single-axis positioner + ground rail, a single-axis positioner + ground rail, a handling robot + gantry, a welding robot + gantry, a lifting and positioning mechanism, and a small component loading flow line.

[0070] The single-axis positioner plus the ground rail is the first conveyor table 8, and the single-axis positioner plus the ground rail is the drive device 6.

[0071] The work process is as follows:

[0072] Base plate assembly welding module operation: First, the base plate components, including upper and lower pulley supports and chain seats, are manually placed on the second material placement rack. The second material handling device picks up the base plate body from the moving vehicle and places it on the base plate assembly welding worktable. Then, the second material handling device picks up a base plate component from the second material placement rack and places it in the corresponding position on the base plate body. The second welding robot assembly first spot welds the base plate component. Simultaneously, the second material handling device picks up the next base plate component and places it on the base plate body. After spot welding is completed, the second welding robot assembly performs full welding. The welded semi-finished base plate assembly is moved from the base plate assembly welding worktable to the base plate assembly conveyor by the second material handling device, ready for the next step.

[0073] The column assembly welding module operates synchronously with the base plate assembly welding module. After the bending equipment bends the column body, it is automatically conveyed to the non-powered conveyor line. The non-powered conveyor line releases the column body onto the main conveyor line, which then conveys it to the lifting and positioning device. The lifting and positioning device lifts the column body, while a single-axis positioner at one end of the lifting and positioning device clamps and flips the column body to accommodate the welding of column accessories at different positions. These column accessories include wire guide grooves and safety toothed plates. The first material handling device picks up the column accessories from the first material conveyor platform and places them on the corresponding positions on the four sides of the column body on the lifting and positioning device. The first welding robot assembly performs spot welding on these accessories. After spot welding, the lifting and positioning device descends, placing the column assembly onto the main conveyor line and then conveying it to the column base plate assembly welding module for the next processing step.

[0074] The column base plate assembly welding module operates as follows: The column assembly from the column assembly welding module arrives above the lifting and positioning device. The lifting and positioning device lifts the column assembly, and a single-axis positioner at one end of the lifting and positioning device clamps and fixes the column assembly. Simultaneously, the third material handling device first picks up the semi-finished base plate assembly from the base plate assembly conveyor table and places it onto the base plate assembly alignment machine at one end of the lifting and positioning device. The single-axis positioner and the base plate assembly alignment machine move relative to each other until the base plate assembly and the support assembly are combined. Then, the rotation angle of the single-axis positioner and the base plate assembly alignment machine is adjusted adaptively, and the third welding robot assembly performs spot welding on both. At the same time, the third material handling device picks up the accessories from the third material stacking table and places them onto the semi-finished column. The third welding robot assembly performs spot welding on them. The third material handling device then retreats, and the fourth welding robot assembly performs full welding on each weld seam. After welding is completed, the lifting and positioning device descends, placing the finished product onto the main conveyor line, which then releases it to the accumulation conveyor line.
