1. Potion Tank Body:
Generally used materials are PP, PVC, stainless steel. If you do not need to heat can use PVC tank, the temperature below 70 °C can use PP tank, if the temperature exceeds 70 °C, you need to use stainless steel tank, but the electroplating tank is not available stainless steel tank (metal tank 0. In continuous plating, there are denominator slots and sub-slots.
The mother tank is used for electroplating solution, and the child tank is for plating. At present, the child and mother groove are separated, the same body, and share three ways. The design of the main tank structure is relatively simple, only considering the factors such as water flow, stirring, steady flow, positioning, and the distance between yin and yang.
2. Groove base frame:
There are generally derivative shelves of plastic medicine trough, angle iron, stainless steel square tube, black iron paint and so on. In order to consider the strength and corrosion resistance, it is recommended to use stainless steel square pipes.
3. Water Inlet System:
Generally, pure water and tap water are used. Water intakes are provided on each medicine trough to replenish the water level and clean the trough. In order to avoid water pipe leakage or human negligence, the electroplating tank is not equipped with a water inlet device.
4. Drainage System:
General drainage needs to be classified and then set up a drainage system. The waste water of terminal continuous electroplating is classified as acid liquid, alkali liquid, nickel liquid, gold liquid, tin and lead liquid, etc. It is recommended to use more than one inch of pipe for each groove drain.
The drainage effect is better. The general washing tank is equipped with a single drain valve, and each electroplating medicine tank is equipped with a double drain valve to avoid human negligence will drain the medicine. Each water tank is provided with overflow pipes to avoid full water flowing to the other tank.
5. Exhaust system:
Electroplating equipment needs to have a seal (that is, an upper cover) to have an exhaust effect. A suction outlet is arranged in the medicine tank which mainly produces waste gas, and the suction volume can be adjusted. Due to the high water content in the gas, it is necessary to have a drainage device. The extracted gas must also be treated as waste gas.

6. Electric heating system:
Because the medicine tank needs to be heated, the heating system is very important. The general heating system consists of heater, temperature sensor, liquid level sensor, temperature setter, TIMER, alarm and so on.
As safety issues are taken into account, an automatic power outage system must be installed without water. Titanium is the longest material to soak in the potion, but in the strong alkali medicine sink, stainless steel or Teflon and other materials are recommended.
7. Cooling system:
There are general direct freezing method and indirect freezing method. The direct freezing method is to pump the potion into the freezer to cool, and this method has a good freezing effect. The indirect freezing rule is to drain the cooling water pipe in the potion tank but the water pipe indirectly freezes the potion. This method has poor freezing effect and is difficult to clear the trough.
The heat dissipation mode of the freezer is water cooling method (with cooling water tower) and air cooling method (fan). If tin-lead potion can maintain 24-hour low temperature state, the potion will not cause turbid situation.
8. Electronic control system:
In addition to the electronic control of the above heating and cooling system, there are pump, filter, shock machine, rectifier, transmission, oven, blower and so on, which are usually controlled by power control box. The rectifier and transmission are set as the connecting device.
9. Scrape equipment:
In continuous electroplating equipment, scraping methods include rubber scraper, brush, air blowing, water absorption sponge and so on. Among them, the blowing method is the best, but the cost is the highest. At present, there are air compressor generation and blower generation. The terminal structure is poor (easy to deform) is not suitable for brush and scraper, silicone rubber scraper is suitable for flat terminal.
10. Drying system:
After electroplating, the water droplets on the terminal surface must be removed, otherwise the drying effect will be very poor. Generally, dry ovens are HEATER or IR, and dried in a hot air cycle. The oven shall have a temperature control device.
11. Discharge system:
The general discharge mode is horizontal and vertical. The discharge area is equipped with a paper rolling device, a connecting switch and a positioning guide wheel. If the production speed is fast, it should be equipped with buffer wiring.
12. Receiving system:
The general way of receiving materials is horizontal and vertical. The receiving area shall be provided with a transmission device (some special transmission devices are not in the receiving system), a counting device, a connecting switch, a receiving device, a paper turntable, a positioning guide wheel, and a buffer connection if the production speed is fast.
13. Pump filter:
General horizontal pump and vertical pump, its specification is distinguished by HP horsepower, the greater the horsepower, the greater its flow rate, the filter core commonly used specifications are 1 μ, 5 μ, 10 μ, the smaller the μ number, the smaller the filterable particles, the better the filtration effect.
It is generally recommended to use 1 μ in gold trough, 1 μ in palladium nickel tank and 5 μ filter center in others, and check regularly every week. The longer the filtration time, the better the effect, such as 24 hours filtration is the best.
14. Rectifier:
At present, there are controllable silicon rectifier, electrocrystal rectifier, variable frequency rectifier, pulse rectifier and so on. Because the DC wave degree will affect the current density range, the smaller the filter degree is, the wider the operable current density will be. Usually, the filtering degree must be less than 3%. Among them, the frequency conversion rectifier is the best, and the filtering degree is about 0.1%.
15. Locator:
The methods commonly used in the medicine tank are fixed (used in full immersion) and adjusted (when plating or considering current distribution), while the materials used are acid-alkali and heat-resistant plastics, glass, ceramics, etc. As for locators outside the medicine trough, stainless steel is mostly used.
16. Yin and anode:
The specification of cathode (anode) conductive wire is = = maximum operating current / 4 * (number of lines). If the current is 100 amperes and there are two conductors, the cross section of the conductor needs to be at least 12.5 square millimeters. The anode can be divided into soluble anode and insoluble anode.
Dissolved anode is used in supplement (common metal electroplating is common), and insoluble anode is used as auxiliary anode, such as nickel metal as dissolved anode and titanium basket as nickel metal, so it is insoluble anode. Precious metal electroplating usually uses insoluble anodes and is conductive well. Precious metal insoluble anodes (such as platinum) are used.
Cathode generally refers to plating parts, but the cathode conductive head for conductive cathode parts described here, the general cathode conductive head uses copper alloy or stainless steel material, must consider conductive, corrosion resistance, operation, cost, before the material can be determined. However, the contact between the cathode conductive head and the plating parts needs to be good, and the smaller the friction, the better.
17. Agitator:
In order to promote electroplating efficiency, increase electroplating uniformity and increase current density, it is necessary to strengthen stirring effect. Generally, there are strong flow stirring, cathodic concussion stirring, ultrasonic stirring, air stirring and so on.
