四.Treatment Process:

1. Degreasing
   (1) 6jig(rack)/ tank x 1 tank=6jig(rack)
   (2) treatment time: 2-5min
2. Alkaline Etching
   (1) 6jig(rack) / tank x 2 tank=12jig(rack)
   (2) treatment time: 3-15min
3. Neutralization
   (1) 6jig(rack) / tank x 1 tank=6jig(rack)
   (2) treatment time: 1-5min
4. Anodizing
   (1) 2jig(rack)/tank x 3tanks = 6jig(rack)
   (2) Current density: 130A/m²
   (3) Process time: 30min
   (4) Unprocess time: 10min
   (5) Total time 30+10=40min

(6) Average anodizing layer : 0.36*1.3*30*0.77 =10.81um

5. Colour 1

1) Clour process: Mix Salts

八, Composition and description of the automatic control system

1, This system is applicable to the semi-automatic production line of aluminum oxide anodization. According to its process specifications, the system is planned to adopt an upper computer monitoring and management system (composed of an industrial control computer IPC), a lower computer control execution system (PLC), detection components, and execution devices. There are two operation modes in terms of operation: manual and semi-automatic. When the system is running normally, it is semi-automatic. Based on the input of feeding data, the crane can identify the slot position in semi-automatic mode and execute corresponding oxidation, coloring and other processes. The temperature of the slot liquid meets the process requirements in semi-automatic control. In semi-automatic mode, the single step operation of the crane and related equipment can be controlled in the central control room. In manual mode, the operation can be carried out through on-site operation buttons.
 

2, Semi-automatic given control system
(1) The start and stop of the oxidation power supply can be controlled manually or by the PLC of the automated production line;
(2) PLC setting for oxidation working time timer or automated production line;
(3) The output current or voltage value and operation process of the power supply are set by the production line PLC and the central control system;
(4) The operating parameters and status can be transmitted to the upper PC of the production line through the communication interface;
(5) You can preset the set values according to the process and provided parameters.

九, Automatic transfer of material on the production line and transfer of material beams in the workshop

Automatic feeding and unloading lifting device:

Setting: Each feeding position is a single beam for feeding and unloading, and the lifting device is equipped with conveying equipment before and after the lifting device. The empty beam and the solid beam are separated and the six rows are used as a unit to ensure that the six rows of materials are processed in the same process, avoiding the need to allocate processes and occupying driving resources and efficiency.
