Firstly, adjusting the position of the clamping plate 601, pulling out the clamping rod 606 by an operator, pushing the driving block 605 to the first position of the limiting hole, driving the rotating frame 603 to rotate in opposite directions by the linkage rod 604, driving the clamping plate 601 to move aside, and then pressing the clamping rod 606 to enable the clamping rod 606 to extend into the first position of the limiting hole, and fixing the driving block 605;
Secondly, adjusting the position of the second mounting frame 503, an operator presses the first elastic telescopic rod 5021 inwards, simultaneously rotates the connecting frame 502, the end head of the first elastic telescopic rod 5021 slides along the arc-shaped sliding chute 5011 to extend into the first embedding hole, loosens the first elastic telescopic rod 5021, and the connecting frame 502 is fixed, and the second mounting frame 503 is vertical and opposite to the mobile testing device 4;
Subsequently, the rectangular light source 7 is placed between the conveying rollers 504 on one side, the servo motor III 505 is started, the conveying rollers 504 rotate, and the rectangular light source 7 is conveyed to the middle position; in the moving process of the rectangular light source 7, an operator presses the two pressing plates 5062, the two pressing plates 5062 are close to each other and drive the two sliding frames 506 to be close to each other, so that the two rotating rods 507 on the same sliding frame 506 rotate and are far away from each other, namely, the opening angle is increased, the tension spring stretches, and the spacing roller 508 on the two rotating rods 507 is increased; the rectangular light source 7 slides along the limit roller 508 and passes through the transport roller 504 on the other side, the worker releases the pressing plate 5062, and the rectangular light source 7 is fixed;
Finally, performing a lamp bead test, wherein the second servo motor 408 drives the driving gear 409 to rotate, and the driving gear 409 drives the gear ring 404 to rotate, so that the inner slide rail 4041 and the outer slide rail 4011 are in butt joint to form a complete vertical slide rail; the servo screw 402 drives the lifting block 403 to move to the first mounting frame 405, and the servo electric cylinder 4031 drives the clamping block 4032 to extend into the limiting frame, so that the lifting block 403 and the first mounting frame 405 are relatively fixed; when the first mounting frame 405 moves up and down, the fixing rod 4051 is separated from the fixing hole 4042; the servo screw 402 drives the lifting block 403 and the first mounting frame 405 to rise to the position flush with the first row of lamp beads of the rectangular light source 7; the first servo motor 4073 drives the sliding gear 4072 to rotate, so that the sliding block 406 is driven to move along the sliding rack 4071, the optical light head 2 moves along with the sliding block 406 to detect the whole row of lamp beads one by one, and signals are transmitted to the measuring terminal 3; after testing of one row of lamp beads, the first mounting frame 405 moves down to the next row until all lamp beads are tested;
After the test is completed, the servo motor III 505 drives the conveying roller 504 to rotate, the rectangular light source 7 is conveyed out, and the tension spring drives the rotating rod to return to the original position.
2. When testing individual beads of the circular light source 8 (as shown in fig. 3):
Firstly, adjusting the position of the second mounting frame 503, an operator presses the first elastic telescopic rods 5021 inwards, simultaneously rotates the connecting frame 502, the end heads of the first elastic telescopic rods 5021 slide along the arc-shaped sliding grooves 5011 to extend into the second embedding holes, loosens the first elastic telescopic rods 5021, and the connecting frame 502 is fixed to give up a test space;
Secondly, adjusting the positions of the clamping plates 601, pulling out the clamping rods 606 by an operator, pushing the driving block 605 to the second position of the limiting hole, driving the rotating frame 603 to rotate in opposite directions by the linkage rod 604, enabling the two clamping plates 601 to face each other, and then pressing the clamping rods 606 to enable the clamping rods 606 to extend into the second position of the limiting hole, and fixing the driving block 605;
Then, an operator dials the clamping plates 601 to two sides, the second elastic telescopic rod 602 is contracted, the circular light source 8 is placed between the two clamping plates 601, the clamping plates 601 are loosened, the second elastic telescopic rod 602 rebounds, and the two clamping plates 601 clamp the circular light source 8;
Finally, performing lamp bead test, wherein the servo screw 402 drives the lifting block 403 and the first mounting frame 405 to move to the position of the fixing hole 4042, and the fixing rod 4051 automatically enters the fixing hole 4042 to enable the first mounting frame 405 and the gear ring 404 to be relatively fixed; the servo electric cylinder 4031 drives the clamping block 4032 to be separated from the limiting frame; the first servo motor 4073 drives the sliding gear 4072 to rotate, so that the sliding block 406 is driven to move along the sliding rack 4071, and the optical pick-up head 2 moves to the center of the first mounting frame 405 (namely, the center of the gear ring 404) along with the sliding block 406 for detection; after the detection of the lamp beads at the circle center of the gear ring 404 by the optical light-collecting head 2 is completed, the sliding block 406 moves outwards for a certain distance, the lamp beads on the first circle from inside to outside are arranged on the optical light-collecting head 2, the second servo motor 408 drives the driving gear 409 to rotate, the driving gear 409 drives the gear ring 404 to rotate, the lamp beads on the first circle are detected by the optical light-collecting head 2, and signals are transmitted to the measuring terminal 3; after the detection of the lamp beads in one circle is completed, the sliding block 406 drives the optical light-collecting head 2 to move to the next circle until the test of the lamp beads in all circles is completed;
after the test is completed, the operator pulls the clamping plate 601 to both sides and removes the circular light source 8.
Embodiment two:
the present embodiment is based on the first embodiment, and the number and arrangement of the optical light-emitting heads 2 on the slider 406 are changed to accommodate more rectangular light sources 7 and circular light sources 8, and the plurality of optical light-emitting heads 2 can improve the testing efficiency.
