Mode two
A kind of testing, sorting device that is used for vertical LED, it comprises dish to be tested, test panel, separator plate and test macro.Said dish to be tested and separator plate all are made as disk rotatable, that move horizontally and move up and down, place on the dish to be tested of test panel one side and are equipped with chip, and separator plate places the opposite side of test panel.Test panel upper surface one circle is uniformly distributed with a plurality of standing grooves, and each standing groove bottom connects vacuum tube, and the test panel top is equipped with the probe and the probe that can move horizontally and move up and down, and probe is connected with test macro respectively with probe.Be provided with the test suction nozzle that can rotate transposition between dish to be tested and the test panel, be provided with the sorting suction nozzle that can rotate transposition between separator plate and the test panel.
The present invention has following beneficial effect owing to adopted above-mentioned structure:
1. a kind of device that is used for the light emitting diode (LED) chip with vertical structure testing, sorting is provided, a difficult problem that can't automatic test after having solved present light emitting diode (LED) chip with vertical structure and dissociating;
2. apparatus of the present invention have been given full play to the advantage of continuous productive process, couple together and can work simultaneously chip testing and sorting are organic, can effectively improve the speed of testing, sorting.
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described further.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Specific embodiment
Embodiment one
Referring to Fig. 1, the present invention includes dish to be tested 102, test panel 104, separator plate 110 and test macro 108.Dish to be tested 102, test panel 104 and the disk of separator plate 110 for rotating, move horizontally and move up and down.Dish 102 to be tested places on the side of test panel 104 and puts chip 101, and separator plate 110 places the opposite side of test panel 104.Test panel 104 upper surfaces one circle is uniformly distributed with a plurality of standing grooves 105, and each standing groove 105 bottom connects vacuum tube.The corresponding position of the standing groove 105 of test panel 104 tops and test position is equipped with probe 107 and probe 106, and probe 107 is connected with test macro 108 respectively with probe 106.Be provided with the test suction nozzle 103 that can rotate transposition between dish 102 to be tested and the test panel 104, be provided with the sorting suction nozzle 109 that can rotate transposition between separator plate 110 and the test panel 104.
Testing, sorting step when the present invention uses is:
The first step: the chip 101 after expanding crystalline substance is positioned on the dish 102 to be tested, and dish 102 to be tested can be selected the general blue film of industry for use.By test suction nozzle 103 chip 101 is drawn to the standing groove 105 of test panel 104 test positions.Then, test panel 104 raises, and the test position vacuum is opened.The probe 107 of test position top distinguishes according to predefined test pattern in the test macro 108 whether the position, the left and right sides of chip 101 and the anglec of rotation be suitable.
Second step; Test panel 104 rises; And move a correction according to the chip of distinguishing 101 situations; Finally make the electrode on the chip 101 can accurately run into probe 106, the photoelectric characteristic of beginning test chip 101 generates these chip 101 pairing bin attribute shelves and preservation according to predefined minute bin condition then.Whenever test the photoelectric characteristic of a chip 101, test panel 104 rotates a step-length, makes next vacant standing groove 105 be positioned at test position, supplies test suction nozzle 103 to draw next chip 101 and is placed in this standing groove 105.
In the 3rd step, test panel 104 descends and chip 101 is rotated to sort location, and the sort location vacuum is closed.Sort location is provided with the sorting camera, and the sorting camera is distinguished the position of this chip 101 according to predefined test pattern, and computer can access the corresponding bin attribute shelves of this chip 101 according to the step-length number that test panel 104 rotates.Sorting suction nozzle 109 is drawn the chip 101 of sort location to separator plate 110.When need changing separator plate 110, test panel 104 can stop operating, and treats that new separator plate 110 rotates after in place more again.
In the 4th step, repeat above step and can finally accomplish testing, sorting a plurality of chips 101.
Embodiment two
The difference of the structure of the embodiment of the invention two and method and embodiment one is; Test panel 104 is fixed, and test suction nozzle 103, probe 107 and probe 106, sorting suction nozzle 109 are then accomplished testing, sorting through moving horizontally and moving up and down to each chip 101 on the test panel 104.
Under most of situation, the test suction nozzle 103 in apparatus of the present invention, test panel 104, sorting suction nozzle 109 are synchronization jobs, therefore can test simultaneously and sorting work, have improved operating efficiency.
