[0002] Electrolytic aluminum is a method of producing metallic aluminum through electrolysis. Electrolytic aluminum anodes are mostly composed of conductive steel claws and inert conductive carbon blocks. During the electrolytic aluminum process, the carbon blocks on the electrolytic aluminum anodes are consumed due to the participation in the electrolytic aluminum reaction, but the conductive steel claws can be reused. In order to smoothly connect the steel claws with the new anode carbon block and complete the subsequent casting work, it is necessary to bite and fix the steel claws with the carbon block together, that is, to install the conductive steel claws on the new carbon block to form a new anode. However, the existing electrolytic aluminum anodes are often difficult to adjust the centering of the anode segments during assembly, and cannot meet the good assembly of various specifications of electrolytic aluminum anode parts. Therefore, it is necessary to continuously improve the assembly workbench of electrolytic aluminum anodes. In addition, during the anode processing process, the assembled anodes need to be transferred to the conveyor line. The transfer process not only realizes the position transfer of the anode group, but also realizes the rotation of the anode group.

[0026] The working process of the present invention is as follows:

[0027] Step 1: The charcoal block conveyor transports the charcoal block to the rotary bite device of the casting station of the present invention, and sends the charcoal block 20 onto the guide roller 9. At this time, the charcoal block longitudinal positioning cylinders 14 on both sides of the charcoal block longitudinal positioning device 8 are actuated, driving the linkage block 25 to rotate, and the linkage block 25 simultaneously drives the right connecting rod 27 and the left connecting rod 24 on both sides to move, and then the right connecting rod 27 and the left connecting rod 24 respectively drive the left charcoal block longitudinal positioning claw 36 and the right charcoal block longitudinal positioning claw 34 to move, so that the left charcoal block longitudinal positioning claw 36 and the right charcoal block longitudinal positioning claw 34 can simultaneously clamp and position the charcoal block 20. At the same time, along the input direction of the guide roller 9, the charcoal block transverse positioning cylinder 26 is actuated to drive the charcoal block transverse positioning claw 19 to rotate, and the charcoal block 20 is clamped and positioned on one side by the charcoal block transverse positioning claw 19, completing the positioning of the charcoal block 20.

[0028] Step 2, when the catenary transports the steel claw 21 to the top of the carbon block 20, the steel claw positioning cylinder 2 is actuated to drive the steel claw positioning arms 22 on both sides to clamp the steel claw 21, thereby clamping the steel claw 21.

[0029] Step three, after the carbon block 20 and the steel claw 21 are fixed, the lifting cylinder 5 is activated to drive the lifting platform 13 to move upward, thereby driving the carbon block 20 on the lifting platform 13 to move upward together, so that the carbon block 20 is docked with the steel claw 21.

[0030] Step 4: After the steel claw 21 is fixed to the carbon block 20, the carbon block 20 needs to be rotated 90 degrees before being sent to the casting station to facilitate casting. At this time, the rotary reduction motor 16 is activated, and the driving gear 15 on the output shaft of the rotary reduction motor 16 drives the driven gear 32 to rotate, thereby driving the turntable 17 to rotate, so that the guide roller 9 fixed on the turntable 17 can be turned, and finally the transmission reduction motor 4 is activated, and the transmission reduction motor 4 drives the guide roller 9 to rotate through the sprocket mechanism 10, thereby driving the carbon block 20 on the guide roller 9 to move, and the carbon block 20 is transferred from the guide roller 9 to the casting station.

[0031] To sum up, the present invention can realize the functions of rotation and lifting, and can position and engage the carbon blocks and steel claws. At the same time, it can also engage the carbon blocks that enter laterally with the steel claws, and then send them longitudinally into the casting machine for casting, thereby realizing steering transportation to meet the requirements of anode assembly work and greatly improve work efficiency.
