The main function of the ion fan is to remove static electricity, and it has outstanding static elimination performance to prevent static pollution and damage. It is an ideal equipment for personal electrostatic protection areas such as electronic production lines and maintenance stations. It is designed for local areas. It has the characteristics of small size, light weight and convenient installation. It can be installed in blocks and is suitable for various places. General ion fans can be divided into desktop ion fans, horizontal ion fans, suspended ion fans, and micro ion fans.
The ion fan produces a large amount of positively and negatively charged airflow that neutralizes the charge on the object. When the surface of the object is negatively charged, it absorbs the positive charge in the gas stream. When the surface of the object is positively charged, it absorbs the negative charge in the gas stream, so that the static electricity on the surface of the object is neutralized. To achieve the purpose of eliminating static electricity. Its daily maintenance work is as follows: The daily maintenance work of the ion fan is mainly to maintain the static elimination effect of the fan and reduce the maintenance rate. The ion fan is used as a static elimination device. In the long-term use, the fan and the discharge needle will contaminate the particles in the air. Floating dust, if not cleaned regularly will reduce the static removal effect, while also blowing residual particles to the product. The main maintenance cleaning work has three aspects: the cleaning of the casing and the discharge needle, the verification of the regular function, and the performance test of the static elimination. 1. Wipe the shell with alcohol. Regularly use the configured brush to clean the discharge needle every week. Four times of discharge needle alcohol wipe in one year, these tasks will keep the static elimination time and residual voltage and other parameters to maintain long-term stability. 2. Verification of the regular function includes: normal display of the power indicator light, alarm light and related switch buttons, and other functions such as heating. Each manufacturer's products will have slight differences, and the products should be routinely verified according to the operating instructions. 3. The static electricity performance test includes: ion balance test and static elimination time test, which are subject to the static test analyzer. If it is found during the test that the static elimination time and residual voltage have a large deviation from the new machine, it should be sent to the factory for ion fan test calibration. The universal offset standard is now within ±10V, and should be returned to the factory for maintenance in high-precision industries above this value. Ion fan is used for the formation of resin products, film processing, etc.; integrated circuit board printing; ESD protection of electronic components; optical equipment, dust removal and removal of precision parts. Ion fan maintenance program:
First, turn the governor switch clockwise to light, that is, turn on the fan, generate ion airflow, increase the wind speed of the fan, turn the governor switch clockwise; turn to the "off" position indicator light off, indicating ion The fan is turned off. To adjust the airflow direction, loosen the bracket plum screw, tilt the body to adjust the up and down position, and then tighten the bracket screw after adjusting. Clean the ion emitter, rotate the head of the cleaning head clockwise to stop, and then turn it repeatedly until it is clean.
Second, the wind speed and electrostatic time of the ion fan are determined by various factors. The two most important reasons are the distance of the ion fan and the wind speed. The air ions are constantly neutralized with each other, and the cations and anions are attracted to each other by static electricity to form a transfer of these charges and recombine. High wind speeds enable them to neutralize further away, and the greater the wind speed, the faster the neutralization. When using an ion fan for electronic assembly, the ionized airflow should cover the working area as much as possible, so that the positive and negative charges on the surface of the object can be well neutralized to maintain neutralization.
3. Clean the launching point of the transmitter. Rotate the cleaning head handle clockwise to stop and let go, then turn it repeatedly until it is clean, at least once a week. The air inlet and ionization outlets should be kept clean to prevent airflow and can be cleaned with a soft brush or compressed air.
Fourth, use the plate load monitor to measure, or use the ion tester to measure the ion balance (residual voltage). The ion fan's output design for the ion volume is stable and fixed. The ion balance is offset due to factors such as voltage fluctuations, ambient air dryness, and the like.
