Specific embodiment
The present invention is described further with specific embodiment below in conjunction with the accompanying drawings:
As depicted in figs. 1 and 2, a kind of led element test platform of the present invention, including the frame 1 for installing each assembly,
Frame 1 is provided with the base plate 2 of inclination, and base plate 2 upper surface is parallel to be provided with first baffle 3 and second baffle 4, base plate 2, first gear
Plate 3 and second baffle 4 surround the transfer passage 5 of inclination；The initiating terminal of transfer passage 5 is connected with feeding mechanism, transfer passage 5
End is connected with the initiating terminal of feed belt 15.
First block piece 6 and the second block piece 7 is telescopic is arranged in second baffle 4, in the present embodiment, the first stop
Part 6 is connected with the first telescopic cylinder 11, and the second block piece 7 is connected with the second telescopic cylinder 12, and the first block piece 6 is along led unit
The conveying direction of part is located at the downstream of the second block piece 7.
First block piece 6 and the second block piece 7 are separated out one section of test for testing led element in transfer passage 5
Passage 8；It is provided with the first relative conductive electrode 9 and the second conductive electrode 10, the first conductive electrode 9 and second in TCH test channel 8
Conductive electrode 10 is all connected with wire.First conductive electrode 9 is fixedly mounted on second baffle 4；Second conductive electrode 10 activity
Setting, specifically, the second conductive electrode 10 is connected with the 3rd telescopic cylinder 13, thus the second conductive electrode 10 and the first conductive electricity
The spacing of pole 9 is adjustable.
So that the attitude that led element enters transfer passage is after feeding mechanism arranges led element in an orderly manner: led electrode
Relative with first baffle 3 and second baffle 4 respectively.During original state, the first block piece 6 stretches out, and the second block piece 7 is retracted,
In the presence of gravity, led element enters TCH test channel 8 along transfer passage, and now the second block piece 7 stretches out so that led element
Position is fixed in TCH test channel.Second conductive electrode 10, under the driving of the 3rd telescopic cylinder 13, stretches out default distance, the
Two conductive electrodes 10 apply certain dynamics to led element so that the led electrode of led elements on either side is conductive with first electric respectively
Pole 9 and the second conductive electrode 10 make electrical contact with, and are now tested according to conventional meanses.After the completion of test, the first block piece 6 contracts
Return, under gravity, led element enters feed belt along transfer passage.After TCH test channel discharged by led element, the
One block piece 6 stretches out again, and the second block piece 7 is retracted so that next led element enters TCH test channel.Repeat the above steps,
Led element can be completed endlessly test.
Abnormal and cannot find in order to prevent led element from testing appearance in TCH test channel 8, the second conductive electrode 10 with
The relative one side of led element is provided with pressure transducer, thus when the second conductive electrode 10 stretches out extruding led element, if pressure
Power exceeds preset range, just sends warning, reminds staff to check.If the second conductive electrode 10 stretches out default distance
Afterwards, pressure is less than preset range, also can send warning.
Because the species of the led element in current industry is various, specification has multiple, for various sizes of led unit
Part is tested, and needs to adjust the width of transfer passage, is easy to led element and glides by preset posture, therefore second baffle 4 is set to can
Activity, specifically, base plate 2 is provided with the length direction two parallel chutes 14 vertical with second baffle 4, and bolt passes through to be slided
Second baffle 4 is installed on a base plate 2 by groove 14, and base plate 2 is provided with the quarter of spacing between measurement first baffle 3 and second baffle 4
Degree chi 18.When needing the width adjusting transfer passage, the position that only need to unclamp the mobile second baffle of bolt and bolt is to rule
Upper corresponding position, then retorque, fixing second baffle.
By the led Component screening of test failure out, it is provided with the side of feed belt 15 initiating terminal in order to further
Scraping wings 16, scraping wings 16 is connected with the 4th telescopic cylinder 17.When the led element test in TCH test channel is unqualified, pusher
Inappropriate led element can be released feed belt by plate 16.It should be noted that the Synchronization Control of pushing course can be according to work
Needing of making selects different modes to realize, and such as the situation and passing through of putting in place of led element monitored by setting infrared sensor
Plc system is realized.
Those of ordinary skill in the art will be appreciated that, embodiment described here is to aid in reader and understands this
Bright principle is it should be understood that protection scope of the present invention is not limited to such special statement and embodiment.This area
Those of ordinary skill can make various other each without departing from present invention essence according to these technology disclosed by the invention enlightenment
Plant concrete deformation and combine, these deform and combine still within the scope of the present invention.
