Description

Chip inductor coiling bonding machine

Technical field

The utility model relates to the electronic component inductance and makes the field, specifically is meant chip inductor coiling bonding machine.

Background technology

Inductor is an inductance coil, is to be enclosed the land on insulation tube by one by lead one circle, and lead insulate each other, and insulation tube can be hollow, also can comprise iron core or magnetic core, is called for short inductance, represents with L.Inductor is pressed the magnetic conductor qualitative classification: hollow coil, ferrite coil, iron-core coil, copper core circle; Classify by job specification: aerial coil, oscillator coil, choking-winding, trap coil, deflection, press the winding structure classification: single layer coil, lattice coil, honeycomb coil.

The major parameter of inductor: inductance value, depend on the number of turns of coil, structure and winding method, reflection inductance coil storage tape can ability, also reflect the ability that produces induced electromotive force when inductor passes through variable-current.Induction reactance: inductance coil is to the size of alternating current inhibition.Quality factor: a physical quantity of expression mass of coil is the ratio of the induction reactance resistance equivalent with it.

Stepper motor is the open loop control element that electric impulse signal is changed into angular displacement or displacement of the lines.Under the situation of non-overload, the frequency and the umber of pulse of pulse signal are only depended in rotating speed of motor, the position that stops, and are not subjected to the influence of load variations, promptly add a pulse signal to motor, and motor then turns over a step angle.The existence of this linear relationship adds that stepper motor has only periodic error and do not have characteristics such as accumulated error.Make in control fields such as speed, positions very simple of controlling change with stepper motor.

Servomotor claims operating motor again, in automatic control system, as executive component, angular displacement or angular speed that the signal of telecommunication of being received converts on the motor reel is exported.It also is the indirect speed change gear of a kind of subsidy motor.Servomotor can make control rate, and positional precision is very accurate.Voltage signal is converted into torque and rotating speed to drive the control object.Servomotor is higher than Stepping Motor Control precision.

Early stage inductance adopts artificial method for winding, and degree of tightness differs during owing to coiling, and flatness is also inconsistent, so unstable product quality, owing to be manually-operated, can't make small size chip product.

Existing coil winding machine, use machinery to wind the line, weld coil two ends joint automatically, but have following two aspect problems:

2) use the lifting and the move left and right of common electric machine control plumb joint, left and right sidesing shifting is inaccurate, and the welding position is not that to take back be exactly to take over, and product appearance is uneven, and qualification rate is not high; Plumb joint is to the pressure transient of pad, the time little when big; When plumb joint pressure is big, easily crushing, presses the side core body and break soldered enamel covered wire, plumb joint pressure hour, enamel covered wire and termination electrode not prison welding are consolidated.

The utility model content

Tight during pine when solving the enamel covered wire that prior art chip inductor coiling bonding machine exists, easy broken string, plumb joint is to the problems such as pressure transient of pad, it is stable to the utility model proposes a kind of enamel covered wire coiling, and welding pressure is stablized manageable a kind of chip inductor coiling bonding machine.

The technical scheme that the utility model uses is as follows:

A kind of chip inductor coiling bonding machine comprises frame, coiling electric motor, mobile motor, wire storage ring, left push rod, right push rod, cylinder, plumb joint, and control system, it is characterized in that: described wire storage ring adopts storage line step motor control to rotate; On the top of wire storage ring, be provided with the stringing ring of connection angle sensor; Angular transducer is electrically connected with storage line stepper motor, when enamel covered wire is under-supply, its pulling force is bigger, angular transducer can rotate than wide-angle, the big voltage of output makes storage line stepper motor faster rotational speed, increases the enamel covered wire supply, otherwise then reduce the enamel covered wire supply, have characteristics such as line sending is steady, quick; Described plumb joint adopts servomotor control lifting, and lifting process is steady, and the lifting accurate positioning prevents that the electrode of plumb joint collision chip wire-wound inductor from causing fragment, lateral plate, broken string etc. or not prison welding admittedly.

The move left and right of enamel covered wire is by enamel covered wire move left and right Electric Machine Control.

As optimization, described coiling electric motor adopts servomotor, and winding turns is accurately controlled.

Described control system adopts two cover cpu systems, and a cover CPU control storage line stepper motor, coiling electric motor and soldering tip move up and down motor; Another set of CPU control mobile motor, enamel covered wire move forward and backward motor and enamel covered wire move left and right motor.

Adopt dual-cpu structure to control three cover servo electrical machinery systems and three cover stepping motor systems respectively in the control of the utility model system, guaranteed not produce the dead point in the control, improved control rate and reliability.

The beneficial effects of the utility model are:

1) wire storage ring adopts stepper motor fit angle sensor, control enamel covered wire supply length, and guarantee that pulling force is stable, and enamel covered wire supply length is accurate, and the enamel covered wire pulling force at every moment all is in stable state, and product quality is guaranteed naturally.

2) the plumb joint servomotor is accurately controlled plumb joint dropping distance and pressure, and decrease speed is slowed down when plumb joint drops near pad especially, and the steady Contact welding contact of plumb joint is welded; Accurately move about soldering tip move left and right Electric Machine Control plumb joint, welding effect is good.

3) adopt two CPU to control the mode of many cover servo electrical machinery systems and stepping motor system respectively, improved control rate and reliability.
