Electroplating equipment Not all positive ions of metal materials can accumulate out of the solution. If the adverse reaction of the recovery of hydroxyl ions to hydrogen on the cathode plays a key role, the positive ions of metal materials cannot be dissolved on the cathode. According to the test, the probability of positive ions of metal materials electrodepositing from the solution can obtain the necessary regularity from the periodic table of elements, Anodic oxidation can be divided into soluble anodic oxidation and insoluble anodic oxidation. Most of the anodic oxidation is soluble anodic oxidation corresponding to the coating, for example, hot galvanizing is zinc anode, nickel/silver plating is silver anodic oxidation, and tin violet lead alloy is tin lead alloy anodic oxidation. However, very few electroplating processes apply insoluble anodic oxidation because of the difficulty of anodic oxidation and melting, For example, platinum or titanium anodes are commonly used for acid alkaline gilding. The positive ions of the main salt of the plating solution are filled by adding the configured standard gold containing aqueous solution. The stainless steel anodizing shall be insoluble anodizing such as pure lead, lead tin aluminum alloy, lead antimony aluminum alloy, etc.
The walking wheel used for driving is a composite structure of steel core and polyester vulcanized rubber. Imported induction coil proximity switch is used for precise parking positioning. Imported soft starter is used for operation and imported well-known brand brake motor is used for operation, which is stable in operation and accurate in parking. Corrosion resistant pump, corrosion resistant column pump and self-priming pump work continuously, with high production efficiency and large production volume. The automatic gantry type electroplating production line, which is operated automatically on the computer and brought back to the flying target for actual operation, greatly alleviates the labor efficiency of employees. The design scheme of the production line is effective, compact and small, and can greatly improve the office environment. Bidirectional thyristor electroplating power supply has two key ways in power circuit construction:
1. Use bidirectional thyristor to carry out voltage transformation at multiple sides of power frequency transformer, and then use silicon tube polyphase rectifier at the secondary side.
2. Immediately use bidirectional thyristor to carry out transformer rectifier at the secondary side of power frequency transformer.
At present, most of the rectifier transformers are three-phase electric five column core environment-friendly transformers, which eliminates the equalization reactor compared with the rectifier method of six phase double reverse active equalization reactor, Electroplating equipment manufacturer The cost is reduced and the efficiency is improved. The maintenance of bidirectional thyristor power supply is complicated. During the maintenance, the common fault position shall be distinguished first. The AC voltage of the digital multimeter shall be 2.3V, the operating pole shall be disconnected, and the operating voltage of the bidirectional thyristor operating pole shall be measured accurately. Adjust the control knob. If the operating voltage is between 0~IV (different bidirectional thyristors, different operating voltage values), then all is normal for part of the open operation, and the bidirectional thyristors are abnormal. If there is no working voltage or the working voltage value is not large, the controller is abnormal. First, check whether the operating frequency and simultaneous operating voltage keyed in by the controller are normal. After clearing the common faults of the transformer with the operating frequency and simultaneous operating voltage, the common faults will be concentrated on the opening board, which needs to be replaced or sent for repair.
The key difference between the vertical electroplating process line and the horizontal electroplating process line depends on the different transportation methods of the circuit board, while the maintenance and repair methods of the relevant tanks are not substantially different. 7d Stop cleaning each hand washing tank for many times Stop cleaning the acid washing tank for many times and replace the tank liquid; Check the automatic spraying installation of the tank body for many times to see if there is any blockage. If there is any blockage, stop dredging immediately; For the conductive rubber support on the barrel plating bath and the tin plating purple bath and the contact position between the anodic oxidation and the Star Wars Empire, the towel can be used to scrub and sandpaper can be used to stop polishing when the cleaning is stopped for many times; The titanium basket and tin bar basket of the barrel plating bath and the tin plating purple bath shall be checked for many times. The worn titanium basket bag and tin bar basket shall be replaced, and the copper ball and tin bar shall be added. After the copper ball and tin bar are added 7 days later, the titanium electrode of the electroplating copper bath and tin bath shall be terminated. 7d also needs to use the high and low electricity flow method to stop the trial consumption, so that the consumption can be stopped after the new copper balls and tin bars are added and the consumption characteristics are stable. Copper balls and anodic oxidation bags shall be cleaned for many times every 95. Every 130~130 days, activated carbon shall be used to stop filtering and cleaning the bath solution for many times, filter out the residue in the bath solution, and stop cleaning the tin bath for many times.
