[0044] Working principle:

[0045] The telescopic end of the material moving cylinder 52 in the driving material moving module 5 is extended outward or retracted inward to drive the material carrying plate 51 to move forward until each positioning cavity hole 511 is located above a corresponding positioning pin unit; then a light source module 7 is placed in each positioning cavity hole 511 so that the multiple conductive spring sheets 71 of each light source module 7 are facing upward and complete the initial positioning, and then the telescopic end of the first lifting cylinder 22 in the positioning module 2 is driven to extend outward to drive each positioning pin unit to move upward with the help of the first lifting bar 23, and then the upper ends of the multiple positioning pins 24 in each positioning pin unit are inserted from bottom to top into a corresponding light source module 7 to effectively prevent the light source module 7 from rotating.

[0046] The telescopic end of the second lifting cylinder 32 in the driving conduction module 3 extends outward to drive the multiple conductive needle units to move downward with the help of the second lifting bar 31, until the multiple conductive needles 33 in each conductive needle unit are overlapped on the multiple conductive springs 71 on the corresponding light source module 7.

[0047] The multiple conductive needles 33 in each conductive needle unit are electrically connected to the test equipment through wires. After the test equipment is started, it can automatically detect whether the circuit of each light source module 7 is normally conductive, and can mark the light source module 7 that fails the test. The above principles are all existing technologies.

[0048] After the test is completed, the telescopic ends of the first lifting cylinder 22 and the second lifting cylinder 32 are driven to retract inwards at the same time to drive each positioning pin unit and each conductive needle unit to leave the light source module 7; then the telescopic end of the material moving cylinder 52 is driven to retract inwards or extend outwards to drive each tested light source module 7 to move backwards with the help of the material carrying plate 51; in addition, the telescopic end of the shift cylinder 44 in the material grabbing module 4 is also driven to retract inwards to drive the lifting beam 41, the two first guide columns 43 and the two sliders 47 with the help of the moving beam 42. Move forward until each pneumatic finger 46 located on the lifting beam 41 moves to directly above a corresponding light source module 7; then, drive the telescopic end of the third lifting cylinder 45 to extend outward to drive each pneumatic finger 46 to move downward with the help of the lifting beam 41, and at the same time drive the two jaws of each pneumatic finger 46 to separate from each other until the two jaws of each pneumatic finger 46 are located on both sides of a corresponding light source module 7; finally, drive the two jaws of each pneumatic finger 46 to move closer to each other to clamp each light source module 7.

[0049] The telescopic end of the third lifting cylinder 45 is driven to retract inward so that each light source module 7 moves up until it leaves each positioning cavity 511, and then the telescopic end of the shift cylinder 44 is driven to extend outward so that each light source module 7 moves backward in the same way, until each light source module 7 is located above the end opening of the discharge hopper 69; and then the telescopic end of the third lifting cylinder 45 is driven to extend outward so that each light source module 7 moves down in the same way until it is close to the end opening of the discharge hopper 69.

[0050] If the test results of each light source module 7 are qualified, the telescopic end of the screening cylinder 68 in the screening module 6 is driven to retract inward to drive the gear 66 to rotate with the help of the moving rack 67, and then the outer edge of the screening plate 65 is driven to swing backward with the help of the shaft 62 until the outer edge of the screening plate 65 is close to the rear inner wall of the opening of the second slot 103; when each pneumatic finger 46 releases each light source module 7, each light source module 7 will pass through the second slot 103 through the discharge hopper 69, and then slide out outward along the top outer wall of the first guide plate 63 under the obstruction of the screening plate 65 to realize the automatic classification and collection of qualified products.

[0051] If the test results of more than one light source module 7 are unqualified, the telescopic end of the screening cylinder 68 in the screening module 6 is driven to extend outward to drive the outer edge of the screening plate 65 to swing forward in the same way, until the outer edge of the screening plate 65 is tightly against the front inner wall of the opening of the second slot 103; then, each light source module 7 that fails the test is released to make each unqualified light source module 7 tilted along the top outer wall of the second guide plate 64 under the obstruction of the screening plate 65 in the same way. The light source modules 7 that fail the test are screened out and discarded; the telescopic end of the screening cylinder 68 is then driven to retract inward to drive the outer edge of the screening plate 65 to swing backward in the same way, until the outer edge of the screening plate 65 is tightly attached to the inner wall behind the opening of the second slot 103; finally, each of the remaining light source modules 7 is released to slide outward along the top outer wall of the first guide plate 63 in the same way to be classified into the group that passes the test.

[0052] When each light source module 7 is subjected to a conduction test, the telescopic end of the adjusting cylinder 54 in each barcode inspection unit can also be driven to extend outward to drive each barcode scanner 55 to move forward, and then the barcode scanner 55 is started so that its sensing end scans the barcode on the outer wall on the rear side of the light source module 7, thereby confirming the product number to prevent errors or duplications.

[0053] The utility model can automatically complete the steps of positioning, wiring and discharging the light source module 7 without manual assistance, thereby simplifying the operation steps to reduce labor costs, and can operate multiple light source modules 7 at the same time, thereby effectively improving work efficiency; in addition, the utility model can also automatically screen the light source modules 7 according to the test structure to further improve work efficiency, and can also automatically scan the barcode corresponding to each light source module 7 for verification, thereby increasing functions to further simplify the operation steps.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some of the technical features therein with equivalents.
