The performance index of inductance coil is mainly the inductance. In addition, the wire winding the inductance coil generally has a certain resistance, which is usually very small and can be ignored. However, when the current flowing through some circuits is large, the small resistance of the coil can not be ignored, because a large current will consume power on the coil, causing the coil to heat or even burn out. Therefore, sometimes the electrical power that the coil can bear should be considered.

"Inductance coil is a device that works based on the principle of electromagnetic induction. When a current flows through a wire, a certain electromagnetic field will be generated around the wire, and the wire of the electromagnetic field itself will induce the wire within the range of the electromagnetic field. The effect on the wire that generates the electromagnetic field itself is called" self induction " "That is, the changing current generated by the conductor itself generates a changing magnetic field, which further affects the current in the conductor; the effect on other conductors within the electromagnetic field is called" mutual inductance "."

Packaging machine is a kind of smart card production equipment. The module is firmly pasted in the slot hole on the card conforming to ISO standard after a certain time and pressure hot welding with hot melt adhesive. Encapsulation machine is generally used for IC card and SIM card encapsulation. According to different settings, one card, one chip and one card multi chip packaging can be realized.

Inductance coil dispensing is an automatic dispensing operation aimed at the gap between the inductance coil and the base plate to cement the inductance coil. Both sides need to carry out dispensing, which requires four-axis dispensing operation based on the original three-axis dispensing manipulator to ensure the same amount and effect of dispensing on both sides.

Inductance coil dispensing is an automatic dispensing operation aimed at the gap between the inductance coil and the base plate to cement the inductance coil. Dispensing is required on both sides. Four axis dispensing operation is required based on the original three-axis dispensing manipulator to ensure the same amount and effect of dispensing on both sides.

Inductance is the ratio of the magnetic flux of the conductor to the current producing the alternating magnetic flux generated in and around the conductor when the alternating current passes through the conductor. When DC current passes through the inductor, only fixed magnetic lines of force appear around it, which does not change with time; However, when AC current passes through the coil, there will be magnetic lines of force around it that change with time. According to Faraday's law of electromagnetic induction - magnetoelectricity, the changing magnetic lines of force will produce induced potential at both ends of the coil, This induced potential is equivalent to a "new power supply" ". when a closed loop is formed, the induced potential will generate induced current. According to Lenz's law, the total amount of magnetic lines of force generated by the induced current should try to prevent the change of the original magnetic lines of force. Since the change of the original magnetic lines of force comes from the change of external alternating power supply, from the objective effect, the inductive coil has the characteristics of preventing the change of current in AC circuit. The inductive coil has the characteristics of The characteristic of inertia in mechanics is similar. It is called "self induction" in electricity. Usually, sparks will occur at the moment when the knife switch is opened or turned on. This is caused by the high induced potential generated by the self induction phenomenon. In short, when the inductance coil is connected to the AC power supply, the magnetic field line inside the coil will change with the alternating current, resulting in the continuous electromagnetic induction of the coil. This electromotive force generated by the change of the current of the coil itself is called "self induced electromotive force". It can be seen that the inductance is only a parameter related to the number of turns, size, shape and medium of the coil. It is a measure of the inertia of the inductance coil and has nothing to do with the applied current.

Detection broadcast (1) When selecting and using inductive coils, we should first think about the inspection and measurement of coils, and then judge the quality and advantages and disadvantages of coils. In order to accurately detect the inductance and quality factor Q of inductive coils, special instruments are generally required, and the test method is complex. In practical work, this kind of detection is generally not carried out, but only the on-off inspection of coils and the size of Q value Judgment. [1] First measure the DC resistance of the coil with the resistance gear of the multimeter, and then compare it with the original determined resistance or nominal resistance. If the measured resistance is much larger than the original determined resistance or nominal resistance, Even the pointer doesn't move (the resistance value tends to infinity x) it can be judged that the coil is broken; if the measured resistance value is very small, it can be judged that it is a serious short circuit or a local short circuit, which is difficult to compare. In these two cases, it can be judged that the coil is bad and can not be used. If the measured resistance is not different from the original determined or nominal resistance value, it can be judged that the coil is good. In this case, we can judge according to the following: In this case, judge the quality of the coil, that is, the size of the Q value. When the inductance of the coil is the same, the smaller the DC resistance is, the higher the Q value is; The larger the diameter of the wire used, the larger the Q value; If multi strand winding is adopted, the more strands of conductor, the higher Q value; Coil frame (or iron core) the smaller the loss of materials used, the higher the Q value. For example, when high silicon silicon steel sheet is used as iron core, its Q value is higher than that when ordinary silicon steel sheet is used as iron core; the smaller the coil distributed capacitance and magnetic leakage, the higher the Q value. For example, the Q value of honeycomb wound coil is higher than that of flat winding, which is also higher than that of random winding; when the coil has no shielding cover and there are no metal components around the installation position, its Q value is higher If the value is high, on the contrary, the Q value is low. The closer the shield or metal component is to the off-line coil, the more serious the Q value decreases; The position of magnetic core shall be properly arranged; The antenna coil and the oscillation coil shall be perpendicular to each other, which avoids the influence of mutual coupling. (2) The coil shall be visually inspected before installation Before use, check whether the structure of the coil is firm, whether the wire turns are loose and loose, whether the lead contacts are loose, whether the magnetic core rotates flexibly, whether there are sliding buckles, etc. After these aspects are checked and qualified, the installation can be carried out. (3) If the coil needs fine adjustment during use, the fine adjustment method shall be considered Some coils need to be fine tuned during use, and it is inconvenient to change the number of coils. Therefore, the method of fine tuning should be considered when selecting. For example, a single-layer coil can use the method of removing the trapped coil near the end point, that is, 3 ~ 4 turns are wound around one end of the coil in advance. During fine adjustment, the inductance can be changed by moving its position. Practice shows that this regulation method can fine tune the inductance of ± 2% - ± 3%. For coils used in short wave and ultrashort wave circuits, half a turn is often reserved for fine adjustment. Move or turn this half turn to change the inductance and realize fine adjustment. The fine adjustment of multi-layer segmented coil can be realized by moving the relative distance of one segment, and the number of turns of the movable segment shall be 20% - 30% of the total number of turns. Practice has proved that this fine-tuning range can reach 10% - 15%. For a coil with a magnetic core, the coil inductance can be fine tuned by adjusting the position of the magnetic core in the coil tube. (4) When using the coil, pay attention to maintaining the inductance of the original coil Do not change the shape of the coil when the coil is in use. Size and distance between coils, otherwise it will affect the original inductance of the coil. In particular, the higher the frequency, that is, the fewer coils. Therefore, the high-frequency coil used in TV is generally sealed and fixed with high-frequency wax or other dielectric materials. In addition, it shall be noted that during maintenance, the position of the original coil shall not be changed or adjusted at will, so as to avoid detuning fault. (5) The adjustable coil shall be installed for easy adjustment The adjustable coil shall be installed at the easily adjustable position of the machine, so as to adjust the inductance of the coil to achieve the best working state

Blocking action The self induced electromotive force in the inductance coil always competes with the change of current in the coil. The inductance coil has a blocking effect on AC current. The size of the blocking effect is called inductive reactance XL, and the unit is Ohm. The relationship between inductance L and AC frequency f is XL = 2 π fl. inductors can be mainly divided into high-frequency choke coil and low-frequency choke coil. Tuning and frequency selection The LC tuning circuit can be composed of inductance coil and capacitor in parallel. That is, if the natural oscillation frequency f0 of the circuit is equal to the frequency f of the non AC signal, the inductive reactance and capacitive reactance of the circuit are also equal, so the electromagnetic energy oscillates back and forth in the inductance and capacitance, which is the resonance phenomenon of the LC circuit. During resonance, the inductive reactance and capacitive reactance of the circuit are equivalent and reverse. The inductive reactance of the total circuit current is the smallest and the current is the largest (referring to the AC signal of F = "F0").
