Abstract
The invention relates to a computer driver, in particular to a method for clearing a fault of a floppy drive photoelectric inductor. The method comprises the following steps: the first step: rotating a screw rod magnetic head of a stepping motor to move to the front side, inserting an anti-dazzling screen into a seam at the middle part of the photoelectric inductor, and then energizing; if the magnetic head does not move, taking out the anti-dazzling screen, when the magnetic head ceaselessly moves backwards, the photoelectric inductor is proved to be not damaged, but off-position, and the off-position problem can be solved through a fine adjustment method; the second step: repeating the first step; if the magnetic head moves backwards after being energized, the photoelectric inductor is proved to be damaged; the photoelectric inductor is only required to be removed and replaced. The method can reduce the noise when a floppy drive is in use and prolong the service life of the floppy drive.
Description
Technical field
The present invention relates to computer drive, particularly a kind of troubleshooting methodology of floppy drive photoelectric sensor.
Background technology
As everyone knows, floppy drive is one of standard configuration of computing machine.As Chinese utility model patent instructions (Granted publication number: CN2859747Y) disclose a kind of fixed sturcture of floppy drive, it comprises: a support, have first, second side plate, above-mentioned CD-ROM drive and floppy drive are arranged on above-mentioned first side plate, and connect above-mentioned second side plate with a side respectively; One locking unit, the one end is fixed on above-mentioned first side plate, and another end has a trip, and extended proficiency shank on the body of the unit that should lock; Wherein, conflict and be arranged at above-mentioned CD-ROM drive and the above-mentioned floppy drive another side with respect to above-mentioned first side plate in above-mentioned locking unit; Above-mentioned housing has a square through hole, and an end of above-mentioned CD-ROM drive and above-mentioned floppy drive exposes outside above-mentioned through hole, and the conflict of above-mentioned trip one side of above-mentioned locking unit is pressed on the inwall of above-mentioned through hole; Above-mentioned housing is limited between above-mentioned handle portion and the above-mentioned trip.Element of the present utility model reduces, and simple in structure, meeting does not have the manufacturing technology of screw equalization trend now.
But floppy drive can send continuous " quack " noise when starting shooting and reading to coil sometimes, and this is the rotation sound of stepper motor and the sound of magnetic head bump floppy drive shell.Run into this phenomenon, existing mode mainly is: shutdown immediately.Otherwise the time might be caused the magnetic head off normal once long, and the chip for driving of stepper motor or stepper motor is burnt in serious meeting.
The reason that produces this fault is: when starting owing to floppy drive, stepper motor drives magnetic head and ceaselessly does homing action (just ceaselessly moving backward).And floppy drive has individual photoelectricity limit induction device, and its effect is the reduction point of restriction magnetic head, thereby makes magnetic head ceaselessly seek reduction point (just ceaselessly doing homing action).Above-mentioned generating noise in seeking the process of reduction point because reduction point is sought incorrect causing.
Summary of the invention
The object of the present invention is to provide a kind of troubleshooting methodology of floppy drive photoelectric sensor, mainly solve existing technical matters in the above-mentioned prior art, the noise when reducing the floppy drive use, the serviceable life of prolongation floppy drive.
For achieving the above object, technical scheme of the present invention is:
A kind of troubleshooting methodology of floppy drive photoelectric sensor is characterized in that: it comprises the steps:
The first step: the screw magnetic head of rotaty step motor moves to the front, inserts in the middle crack of photoelectric sensor energising then with an anti-dazzling screen; If magnetic head is motionless, just take out anti-dazzling screen, when magnetic head is ceaselessly mobile backward, proves that then photoelectric sensor does not damage, but off normal has taken place, solve off normal by fine-tuning mode;
Second step: repeat the first step; The energising back just proves that inductor damages if magnetic head moves backward; It is pulled down, and replacing gets final product.
The troubleshooting methodology of described floppy drive photoelectric sensor is characterized in that: described anti-dazzling screen is the black scraps of paper.
The troubleshooting methodology of described floppy drive photoelectric sensor is characterized in that: in described second step, when changeing element, soldering appliance must ground connection, with the destruction of avoiding static to be brought.
The troubleshooting methodology of described floppy drive photoelectric sensor is characterized in that: if floppy drive itself has the spacing setting nut of magnetic head, need only and regulate this setting nut in the described first step.
By technique scheme, the invention has the beneficial effects as follows:
Use the inventive method can effectively determine the optoelectronic induction fault of floppy drive, the noise when reducing the floppy drive operation prolongs its serviceable life.
Embodiment
The invention discloses a kind of troubleshooting methodology of floppy drive photoelectric sensor, concrete steps are:
The first step: the screw magnetic head with the hand rotaty step motor moves to the front, inserts in the middle crack of photoelectric sensor energising then with black scraps of paper.Will note magnetic head in the process of operation, if it is motionless, just take out black scrip, this is that magnetic head should be able to ceaselessly move backward.If like this, prove that then photoelectric sensor does not damage, but off normal has taken place.The floppy drive that has itself has the spacing setting nut of magnetic head, as long as regulate this setting nut.If there is not setting nut, find photoelectric sensor, try every possible means to finely tune its position.
Second step: repeat the first step.After the energising,, just prove that inductor damages (as long as computer one start, the circuit of floppy drive is just started working, and inductor is also worked simultaneously, the unavoidable year in and year out strike phenomenon that occurs) if magnetic head moves backward.It is pulled down, and replacing gets final product.
In the above-mentioned steps two, when changeing element, soldering appliance must ground connection, with the destruction of avoiding static to be brought.
Being preferred embodiment of the present invention only in sum, is not to be used for limiting practical range of the present invention.Be that all equivalences of doing according to the content of the present patent application claim change and modification, all should be technology category of the present invention.
