Zinc-Silver Battery Negative Film Automatic Production Line Development And Key Technology Research

The zinc-silver battery has high specific energy, high current discharge, stable discharge voltage, high precision, and good security, it is widely used in a variety of weapons and civilian equipment. In space, zinc-silver battery commonly used for rocket guidance, telemetry, spacecraft, etc.; 90% of military missiles are equipped with the zinc-silver battery power. Zinc-silver battery anode plate as an important part of the domestic production is still produced by hand,the increasingly obvious shortcomings, mainly reflected in the product low precision, low productivity, but also harmful to workers in the mercury film negative health. Therefore, to achieve the automatic negative film production is the preparation of the existing negative film a great innovation and progress.The main work includes the following aspects:1. Introduce the negative film structure, hand-made process, and analysis had negative film automatic production needs, the negative film automatic production process, the preliminary design the automatic production of stirring, the pickup, modulus, taking net, painted cream, pressing, stripping, packaging.2. Based on a lot of research and experiments design the coating equipment of the negative electrode paste of automatic production line,and select the zinc paste spit pump、pasted manipulator, automatic feed hopper, the selection of extrusion, solve the difficulties of automatic feed. Next step is pressing process, the choice of pneumatic press machine as the suppression of the power output mechanism, and determine the output pneumatic pressure cylinder press, and then design an automatic mortgage cloth body.3.The main transmission lines and sub-transmission line is the skeleton of the whole production line, design main line and vice-line mechanical structure, and design the positioning mechanism solve the tooling, silver network positioning.4.Design the negative film automatic packaging machine. First, design the principle for the packaging machines,including the first, second, third and fourth packing station and the flip station.5.Based on negative piece molding and packing equipment done the experiment, inspect automatic molding equipment and packaging machine principle and production effect.
