Utility model content
The purpose of this utility model is to provide the feeding mechanism of a kind of feeding interval light-emitting diode detection device even, simple in structure.
The technical solution of the utility model is: the feeding mechanism of light-emitting diode detection device, comprise that one can be by LED by the circular vibrating disk of setting cathode and anode directions auto-sequencing and sending one by one, the bar shaped vibrator being connected with circular vibrating disk, it is characterized in that described bar shaped vibrator and slide unit have the straight trough that inserts and move for LED pin, this two straight trough is connected, the thickness that the width of straight trough is greater than pin is less than the ultimate range between two pins, when LED is moved in straight trough, can not turn to.
The body rear end of described bar shaped vibrator arranges the first motor-driven cam of being controlled by controller, and this cam and bar shaped vibrator body rear end lower surface contact; The bearing pin normal-running fit of bar shaped vibrator front bottom end and setting.Or described bar shaped vibrator body rear end is connected with the disk body of circular vibrating disk by power transmission lever
One side of described bar shaped vibrator is installed the second motor-driven thumb wheel that the stepping motor controlled by controller forms, and the moving tooth of this thumb wheel has stoped a rear LED stirring when last LED moves ahead.
The utility model is because bar shaped vibrator and slide unit have the straight trough that inserts and move for LED pin, this two straight trough is connected, the thickness that the width of straight trough is greater than pin is less than the ultimate range between two pins, when LED is moved in straight trough, can not turn to, for follow-up test operation provides location, guarantee; Dial wheel device can guarantee the test of orderly interval, avoids postorder LED crowded forward; The setting of slide unit; Can make LED accurately be seated in test start bit, keep the spacing distance enough with a rear LED, after preventing, a LED disturbs the test of a LED after last; Controller is controlled the rotating speed of cam, can regulate bar shaped vibrator to be fed forward the speed of LED, forms the cooperation of synchronizeing with the second motor, and simple in structure, is conducive to the cost control of mass production.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the left view of bar shaped vibrator in Fig. 1, slide unit, LED seat stand.
Description of symbols in figure: bar shaped vibrator 1, slide unit 11, slide unit straight trough 111, bar shaped vibrator body 13, body straight trough 131, LED seat stand 15, pivot pin 17, the first motors 18, cam 181, extension block 19, circular vibrating disk 2, power transmission lever 21, LED3, thumb wheel 4, the second motors 41.
The specific embodiment:
With reference to Fig. 1, Fig. 2, in the utility model feeding mechanism, LED can be selected to commercially available prod by the circular vibrating disk 2 of setting cathode and anode directions auto-sequencing and send one by one, as the LED vibrating disk that Dongguan City Chang'an Jian Jia automation equipment factory produces, its per minute discharging quantity is 90-160.Circular vibrating disk 2 is connected with bar shaped vibrator body 13, and the light-emitting diode 3 of circular vibrating disk output is entered in bar shaped vibrator body straight trough 131 successively; Bar shaped vibrator 1 and slide unit 11 have the straight trough that inserts and move for LED pin, the other end of bar shaped vibrator body straight trough 131 is connected with slide unit straight trough 111 upper ends, the LED of body straight trough output is entered in slide unit straight trough successively, the width of above-mentioned straight trough is identical, the thickness that is all greater than LED pin is less than the ultimate range between two pins, LED does not turn in operational process, keep the unified anodal pin of LED at front or negative pole pin front, until landing to LED seat stand arrives test reference position.Extension block 19 belows of bar shaped vibrator body 13 rear ends arrange the cam 181 of the first motor 18 drivings of being controlled by controller by rotating speed, this cam and extension block 19 contact, or bar shaped vibrator body 13 rear ends are connected with the disk body of circular vibrating disk 2 by power transmission lever 191, as shown in phantom in Figure 2, bearing pin 17 normal-running fiies of body 13 front bottom end and setting, like this, the rotation of cam or the drive of circular vibrating disk, body 13 is swung up and down a little around bearing pin 17, constantly will before LED, deliver to the LED seat stand 15 being connected with slide unit 11 lower ends.
One side of bar shaped vibrator body 13 is installed the thumb wheel 4 of the second motor 41 drivings that consist of stepping motor, the moving tooth interval of this thumb wheel is stirred and when last LED moves ahead, has been stoped a rear LED, crowded and disturb last LED test run to avoid waiting in slide unit straight trough the LED of test.The setting of slide unit 11, is for the LED in test bit and an adjacent rear LED provide enough spacing distance, touches an adjacent rear LED pin simultaneously and causes stuck when avoiding vertical pole to stir the LED pin of test bit.
Slide unit one by one sent and entered to bar shaped vibrator by LED by setting-up time interval by thumb wheel, to guarantee that last LED is not when being completed, guarantee that an adjacent rear LED is still stopped by the moving tooth of thumb wheel, thumb wheel has 12 moving teeth as shown, the rotating speed of thumb wheel is controlled by controller, first the per minute LED sendout based on circular vibrating disk, such as 160 of per minutes, the rotating speed of the first motor should be per minute 160/12 and turns.
