Description

Technical Field

[0001] This utility model relates to the field of automated welding technology, and more specifically, to a welding reflow line. Background Technology

[0002] An automated welding production line is a production system integrating automated equipment and control systems, primarily used to efficiently and accurately complete welding tasks. Its core equipment includes welding robots, gantry manipulators, and positioners, which work together to achieve functions such as workpiece handling and welding trajectory planning. In industrial production, automated welding technology has been widely applied to automated production lines to improve production efficiency and product quality while reducing labor costs and intensity. However, existing welding production lines still have some shortcomings: for example, inaccurate tooling positioning during manual loading and unloading leads to poor welding position consistency; the flow of tooling between different workstations is not smooth, resulting in waiting time and affecting the overall cycle time; and heavy tooling is prone to displacement during loading operations, affecting operational safety and positioning accuracy.

[0003] Therefore, automatic welding is widely used in industrial production, but it suffers from problems such as long welding time and inconsistent welding positions, which affect efficiency and quality. Therefore, we have made improvements to this problem and proposed a welding reflow line. Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model. It should be noted that, unless otherwise specified, the embodiments, features, and technical solutions in the embodiments of this utility model can be combined with each other.

[0016] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0017] like Figures 1-5 As shown, this embodiment proposes a welding reflow line, including: A return line consisting of a lifting conveyor line 1 and a double-layer conveyor line 2; multiple workstations set on the return line, including a loading workstation, a welding workstation, and a unloading workstation; a welding robot 4 for automatic welding at the welding workstation; a welding fixture 3 for carrying and positioning the workpiece to be welded; and an insertion and inflation mechanism 5 installed at the loading and unloading workstations for docking with and venting the welding fixture 3 to activate the positioning cylinder on the welding fixture 3. The insertion and inflation mechanism 5 includes a fixed bracket 51, an insertion cylinder 52, a linear bearing 53 and a guide rod 54, a release cylinder 55 and a snap-fit ​​plate 56, and the fixed bracket 51 is fixed to the return line. The linear bearing 53 is provided in two sets, and the two sets of linear bearings 53 are mirror-symmetrical along the interlocking cylinder 52. The linear bearing 53 is fixed on the fixed bracket 51. The center of the linear shaft is slidably connected to the guide rod 54. The interlocking cylinder 52 is fixed on the fixed bracket 51, and the movable end of the interlocking cylinder 52 is fixedly connected to the interlocking female head. The upper end of the interlocking female head is fixedly connected to the disengagement cylinder 55. The movable end of the disengagement cylinder 55 is fixedly connected to the snap-fit ​​plate 56. Guide limit devices are provided on both sides of the line, and pneumatic lifting stoppers are configured as positioning stops to ensure that the tooling weighing up to 500KG will not be displaced during manual operation.

[0018] The plug-in inflation mechanism 5 achieves air supply by connecting the male and female plugs, and achieves rapid separation by disengaging the cylinder 55 and the snap-on pressure plate 56.

[0019] The loading and unloading stations are equipped with photoelectric detection devices to detect when the tooling is in place and trigger the insertion and inflation action.

[0020] The reflow line can automatically reflow one welding fixture at position 3, facilitating continuous operation.

[0021] Specifically, the welding return line is mainly composed of a lifting conveyor line 1 station 1, three double-layer conveyor lines 2 station 2, station 3 and station 4, and another lifting conveyor line 1 station 5, connected end to end. The welding robot 4 is usually connected above station 3 and station 4 of the double-layer conveyor line 2, and the welding fixture 3 circulates on the line.

[0022] The workflow of this application is as follows: Figure 5 As shown: (1) Loading station – Station 1 (lifting conveyor): The line receives the tooling from the lower level and lifts it to the operating height. After the tooling is conveyed to the station, it is stopped by the limit stop. After the photoelectric sensor detects that the tooling is in place, the insertion and inflation mechanism 5 is activated to complete the docking and inflation. The operator puts in the workpiece and positions it. After completion, the operator manually releases it, the insertion mechanism disengages, and the tooling flows to the next station; (2) Loading station - Station 2 (horizontal conveyor): Welding fixture 3 is positioned and stopped by the pneumatic lifting stopper, and the subsequent process is the same as Station 1; (3) Welding stations - Station 3 and Station 4 (horizontal conveying): Welding fixture 3 is transferred to the bottom of welding robot 4 and the welding operation is completed automatically; (4) Unloading station - Station 5 (lifting and conveying): The insertion and inflation mechanism 5 inflates the tooling again, the positioning cylinder is released, the operator takes away the finished workpiece and manually starts the return command, the line automatically sends the empty tooling back to the starting end, and completes one cycle.

[0023] The inflatable insertion mechanism 5 is mounted on the side of a predetermined workstation (workstation one, workstation two, workstation five) on the line via a fixed bracket 51. Its operation is as follows: After the fixture is in place, the insertion cylinder 52 extends, pushing the female insertion head forward along the guide rod 54 to precisely align with the male insertion head on the fixture and open the air passage. After inflation is complete, the disengagement cylinder 55 retracts, pulling down the locking plate 56 to release the female insertion head's locking mechanism, allowing the insertion cylinder 52 to retract smoothly and achieve separation.

[0024] Operators control the start, stop, and release of the equipment via push-button stations at various manual workstations. The entire system is controlled by a PLC program, coordinating the sequence of actions of the conveyor belt, stopper lifting, photoelectric detection, and the insertion and inflation mechanism 5, thereby achieving a fully automated welding production cycle.

[0025] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model.
