Description

Technical Field

[0001] The present application relates to the technical field of aluminum electrolytic cell anode production, and in particular to an automatic production line for a composite steel claw guide rod assembly. Background Art

[0002] Aluminum electrolytic cell anode is one of the important raw materials for electrolytic aluminum production. It acts as a conductor to conduct direct current into the electrolyte layer and also participates in the anode reaction of electrolysis as a carbon material. At present, the production of one ton of electrolytic aluminum consumes about 13,000 to 14,000 kWh of electricity. The electrolytic aluminum industry consumes about 550 billion kWh of electricity per year, accounting for more than 6% of the total electricity consumption in the country.

[0003] The anode guide rod group is the main component of the aluminum electrolytic cell. The anode guide rod group includes the anode guide rod and the anode steel claw. The welding quality of the anode guide rod and the anode steel claw directly affects the working efficiency and power consumption of the aluminum electrolytic cell. In the production of electrolytic aluminum, the anode guide rod group is characterized by large number and easy damage. After damage, it needs to be repaired by welding and then put into use again. The traditional welding method of the anode guide rod and the anode steel claw is to manually grab the anode guide rod and the anode steel claw to be welded and place them on the welding work platform, then manually grab the welding connector and place it between the anode guide rod and the anode steel claw, and then manually weld the welding connector to the anode guide rod and the anode steel claw.

[0004] The problems with the above-mentioned traditional welding method of the anode guide rod and the anode steel claw are: on the one hand, the quality of manual welding is unstable and the welding efficiency is low; on the other hand, since the anode steel claw is usually placed vertically during the transportation process to facilitate transportation, and when welding the anode steel claw to the anode guide rod, the anode steel claw needs to be placed horizontally for ease of welding, so the worker needs to move the vertically placed anode steel claw to the welding work platform first, and then lay the anode steel claw down to place it horizontally on the welding work platform, which is time-consuming and labor-intensive, further resulting in low welding efficiency.

Then, the controller controls the aluminum welding robot arm to weld one side of the steel-aluminum composite sheet 03 to the anode guide rod 02, and controls the steel welding robot arm to weld the other side of the steel-aluminum composite sheet 03 to the anode steel claw 01. After completing the welding of a steel-aluminum composite sheet 03, the telescopic rod of the clamping driving member 105 is controlled to extend, thereby driving the pressing plate 101 to move upward. Then, the welding part grasping device 8 is controlled to grasp the next steel-aluminum composite sheet 03 and place it on the previously welded steel-aluminum composite sheet 03, and then the pressure plate 101 is driven to move downward and press on the upper surface of the steel-aluminum composite sheet 03, and then welding is performed again.

[0047] The implementation principle of the composite steel claw guide rod group automatic production line of the embodiment of the present application is as follows: when working, the anode steel claw 01 is placed vertically on the conveyor belt at the feeding end of the steel claw conveying device 2, and the anode steel claw 01 is conveyed to the unloading end by the conveyor belt. After the conveyor belt conveys the anode steel claw 01 to the unloading end, the anode steel claw 01 falls from the conveyor belt to the receiving space of the turning frame 31, and then the controller controls the turning frame 31 to turn over so that the vertical anode steel claw 01 turns to a horizontal state, and then the controller controls the steel claw driving member 41 to drive the anode steel claw 01 to move along the transfer channel to the steel claw positioning area. When the position sensor detects that the anode steel claw 01 moves to the welding position, the controller controls the telescopic rod of the steel claw driving member 41 to retract to its original position, and then controls the steel claw positioning device 5 to move to fix the anode steel claw 01 on the welding workbench 1. Then, the two ends of the anode guide rod 02 are placed on the conveyor belts of the two belt conveyors respectively, and the anode guide rod 02 is conveyed by the conveyor belts; when the anode guide rod 02 is conveyed to the smooth inclined surface of the guide slide 74, the anode guide rod 02 falls from the conveyor belt and slides along the smooth inclined surface to the support slide rail 72. Then, the controller controls the telescopic rod of the guide rod driving member 75 to extend and push the anode guide rod 02 to slide along the support slide rail 72 toward the anode steel claw 01. When the position sensor detects that the welding end of the anode guide rod 02 and the welding end of the anode steel claw 01 are in contact with each other, the controller controls the telescopic rod of the guide rod driving member 75 to stop extending, and then controls the guide rod clamping assembly 76 to clamp the anode guide rod 02 on the support slide rail 72. After the anode steel claw 01 and the anode guide rod 02 are fixed respectively, the welding part grasping device 8 is controlled to grasp a steel-aluminum composite sheet 03 and place it on the welding workbench 1, and then the telescopic rod of the clamping drive 105 is controlled to contract, thereby driving the connecting plate 102 and the pressing plate 101 to move downward until the pressing plate 101 presses on the upper surface of the steel-aluminum composite sheet 03, thereby pressing and fixing the steel-aluminum composite sheet 03 on the working surface of the welding workbench 1. Then, the controller controls the aluminum welding robot arm to weld one side of the steel-aluminum composite sheet 03 to the anode guide rod 02, and controls the steel welding robot arm to weld the other side of the steel-aluminum composite sheet 03 to the anode steel claw 01. After completing the welding of a steel-aluminum composite sheet 03, the telescopic rod of the clamping drive 105 is controlled to extend, thereby driving the pressing plate 101 to move upward. Then, the welding part grasping device 8 is controlled to grasp the next steel-aluminum composite sheet 03 and place it on the previously welded steel-aluminum composite sheet 03, and then the pressure plate 101 is driven to move downward and press on the upper surface of the steel-aluminum composite sheet 03, and then welding is performed again. After welding is completed, this step is repeated to weld the next steel-aluminum composite sheet 03 until a sufficient number of steel-aluminum composite sheets 03 are stacked and welded so that the anode guide rod 02 and the anode steel claw 01 can be completely connected, thereby completing the welding of the anode steel claw 01 and the anode guide rod 02.After the welding gun welds the anode steel claw 01 and the anode guide rod 02 to form a composite steel claw guide rod group, control the composite plate positioning device 10 to loosen the steel-aluminum composite sheet 03, then control the guide rod clamping assembly 76 to loosen the anode guide rod 02, then control the steel claw positioning device 5 to loosen the anode steel claw 01, then control the telescopic rod of the guide rod driving member 75 to continue to extend and push the composite steel claw guide rod group on the welding workbench 1 toward the steel claw sleeve 201 until the claw of the composite steel claw guide rod group is inserted into the slot 204 of the steel claw sleeve 201, then control the rotating driving member 203 to drive the steel claw sleeve 201 to rotate so that the composite steel claw guide rod group is flipped from a horizontal state to a vertical state, and then the composite steel claw guide rod group is taken away by the staff.

[0048] The beneficial effects of the automatic production line of the composite steel claw guide rod group of the embodiment of the present application are as follows: the automatic production line of the composite steel claw guide rod group of the embodiment of the present application can automatically realize the welding of the anode guide rod 02 and the anode steel claw 01, replacing the traditional manual welding, and can solve the problems of the welding quality deviation, unstable welding quality and low welding efficiency of the products welded by different welders in the traditional manual welding. In addition, in this embodiment, by setting the feed end flipping device 3, the anode steel claw 01 can be automatically converted from a vertical state to a horizontal state, thereby facilitating subsequent welding, and by setting the discharge end flipping device 20, after the anode guide rod 02 and the anode steel claw 01 are welded to form a composite steel claw guide rod group, it can automatically convert it from a horizontal state to a vertical state, thereby facilitating the transfer of the composite steel claw guide rod group, and can further improve the welding efficiency.
