The automation equipment of the LED test table of being made up of above-mentioned feeding structure, assignment test structure and discharging structure is the present invention.
The test process that automatic structure provided of LED test table of the present invention is as follows:
Before testing, the light emitting diode of finishing encapsulation is concentrated in the circular vibrating disk 13, because of more than of vibration light emitting diode meetings are regardless of the inlet end that the direction permutation is delivered to flat shape vibrating disk 14, flat shape vibrating disk 14 moves to catch pawl 15 forward with light emitting diode gradually, when trace routine begins, see also Figure 12, Figure 13, move after small slide plate is vertical, the locating detent group is vertically reach simultaneously, and the material folding pawl opens; See also Figure 14, big slide plate 16 then moves after laterally, and charging set of jaws 4 moves to the light emitting diode place before the catch pawl 15 thereupon, this moment band material pawl group 5 four breach and four positioning ports of locating detent group 6 face successively; See also Figure 15, small slide plate is vertically reach then, and the locating detent group also vertically retreats thereupon, the closed thereupon pin of clamping light emitting diode of material folding pawl 41; See also Figure 16, big slide plate 16 laterally moves forward and resets then, and charging set of jaws 4 brings to a positioning point P0 place with light emitting diode, and first process finishes; See also Figure 17, when moving, promptly begin second process after small slide plate is vertical once more, the material folding pawl opens, and meanwhile, locating detent group 6 vertically moves forward, and entangles light emitting diode with first positioning port 61 and adjusts its position; See also Figure 18, move after big slide plate 16 is then horizontal, before charging set of jaws 4 moves to catch pawl; See also Figure 19, small slide plate vertically moves forward then, the closed thereupon pin of clamping light emitting diode of material folding pawl 41, meanwhile, locating detent group 6 is moved after vertically, and the band material pawl group 5 on the small slide plate is along with small slide plate vertically moves forward, and band material pawl group 5 first breach entangle the light emitting diode of first process; See also Figure 20, big slide plate 16 laterally resets then, and will the transpose light emitting diode of some P0 place first process of band material pawl group 5 first breach brings to the first testing station P1, and charging set of jaws 4 brings to a positioning P0 place, the end of second process with light emitting diode; Equally, when after small slide plate continues vertically, moving, the 3rd process begins, material folding pawl 41 opens, simultaneously, locating detent group 6 vertically moves forward, entangle the light emitting diode at positioning point P0 place with first positioning port 61, adjust its position, entangle the light emitting diode at P1 place, first testing station with second positioning port 62, and it is carried out polarity detect, big slide plate 16 moves after laterally then, and before charging set of jaws 4 moved to catch pawl 15, small slide plate vertically moved forward then, material folding pawl 41 is closed thereupon and clamp the pin of light emitting diode, meanwhile, locating detent group 6 is moved after vertically, and band material pawl group 5 is entangled the light emitting diode at positioning point P0 place with first breach, entangle the light emitting diode of the P1 of place, first testing station with second breach, big slide plate laterally resets then, and band material pawl group 5 first breach bring to the first testing station P1 with light emitting diode, and second breach brings to the second testing station P2 with light emitting diode, charging set of jaws 4 brings to positioning point P0 place with folded light emitting diode, and the 3rd process finishes; When after small slide plate is then vertical, moving, the 4th process begins, material folding pawl 41 opens, simultaneously, locating detent group 6 vertically moves forward, entangle the light emitting diode at positioning point P0 place with first positioning port, adjust its position, entangle the light emitting diode at P1 place, first testing station with second positioning port, it is carried out polarity detects, entangle the light emitting diode at P2 place, second testing station with the 3rd positioning port, testing result according to the 3rd process is rotated or waits for it, big slide plate 16 moves after laterally then, before charging set of jaws 4 moves to catch pawl, small slide plate vertically moves forward then, material folding pawl 41 is closed thereupon and clamp the pin of light emitting diode, meanwhile, locating detent group 6 is moved after vertically, band material pawl group 5 is entangled the light emitting diode at positioning point P0 place with first breach, entangle the light emitting diode of the P1 of place, first testing station with second breach, entangle the light emitting diode at P2 place, second testing station with the 3rd breach, big slide plate 16 laterally resets then, band material pawl group 5 first breach bring to the first testing station P1 with light emitting diode, second breach brings to the second testing station P2 with light emitting diode, the 3rd breach brings to the 3rd testing station P3 with light emitting diode, and the charging set of jaws brings to positioning point P0 place with folded light emitting diode, and the 4th process finishes; The rest may be inferred, when the light emitting diode of the 5th process is fed set of jaws 4 and brings to positioning point P0 place, the light emitting diode that band material pawl group 5 the 4th breach has detected P3 place, the 3rd testing station brings on the pawl 82 that connects material, the do action that so constantly goes round and begins again by band material pawl group 5 and charging set of jaws 4, can carry out automatic test to light emitting diode, and simple in structure.
Although the present invention has done detailed explanation and has quoted some instantiations as proof; but for those skilled in the art; only otherwise leave that the spirit and scope of the present invention can be done various variations or correction is obvious, all should be included within the protection domain of claim of the present invention.
