[0002] In modern lighting technology, LED lamp beads have become one of the widely used light sources due to their advantages of energy saving, high efficiency and long life. LED lamp beads are a kind of semiconductor device, which emits light through the compound of electrons and holes. Compared with traditional incandescent lamps and fluorescent lamps, LED lamp beads have the advantages of small size, low energy consumption, long life, fast response and environmental protection. Because of this, LED lamp beads are widely used in various lighting and display equipment, such as indoor lighting, car lights, display screens, etc. The Chinese patent with application number 202320896174.5 discloses "a pickup device for LED lamp bead production, including a base, the front ends of both sides of the base are fixedly connected with support blocks, and the upper side of the adjacent support blocks is A mounting frame is fixedly connected, and a slide groove is provided at the middle position of the upper and lower front ends of the mounting frame, and a screw motor is fixedly connected at the middle position of the upper outer wall of the right support block, and a screw is fixedly connected at the front end of the screw motor, and a nut pair is threadedly connected to the outer wall of the screw, and a fixed block is fixedly connected at the middle position of the outer wall of one side of the nut pair.

[0040] The cleaning mechanism 5 includes a limit plate 504, a lifting groove 506 and a top plate 507. The limit plate 504 is fixedly installed in the rotating sleeve 503 by bolts. The lifting groove 506 is provided in the middle section of the lifting rod 505. The limit plate 504 is installed in the lifting groove 506 by insertion, and the top plate 507 is fixedly installed on the top of the lifting rod 505 by bolts. The limit plate 504 is inserted into the lifting groove 506 to drive the lifting rod 505 to rotate synchronously with the rotating sleeve 503. When the lifting rod 505 rotates, the cleaning soft brush 514 is driven to rotate through the rotating plate 513, and the bottom of the LED lamp bead is cleaned by the rotating cleaning soft brush 514.

[0041] The cleaning mechanism 5 includes a reset spring 508, a pressure plate 509 and a transmission shaft 510. The reset spring 508 is movably sleeved outside the lifting rod 505 and is located between the rotating sleeve 503 and the top plate 507. The pressure plate 509 is fixedly installed on the front side of the top end of the second connecting plate 301 by bolts, and the transmission shaft 510 is movably installed on the top end of the lifting plate 304 by a bearing. The lifting rod 505 drives the rotating plate 513 to rise and reset through the elastic force of the reset spring 508, so that the LED lamp beads can be put down smoothly, and the gear 511 is meshed with the rack 502 to drive the gear 511 to rotate, so that the transmission shaft 510 rotates with the gear 511. When the transmission shaft 510 rotates, the rotating sleeve 503 is driven to rotate through the transmission belt 512;

[0042] The cleaning mechanism 5 includes a gear 511 and a transmission belt 512. The gear 511 is fixedly installed on the top of the transmission shaft 510 by bolts. The gear 511 is movably connected to the rack 502 by meshing. The two ends of the transmission belt 512 are movably sleeved on the rotating sleeve 503 and the transmission shaft 510 respectively. The rotating sleeve 503 is driven to rotate by the transmission belt 512. When the rotating sleeve 503 rotates, the limit plate 504 inside it is driven to rotate at the same time.

[0043] Working principle: When the present invention is in use, the first cylinder 206 is controlled to retract the translation push rod 207 into the first cylinder 206, and the translation slider 204 and the translation plate 205 are connected by the push plate 208, so that the translation plate 205 follows the translation slider 204 to move on the translation guide rail 203 toward the first cylinder 206. When it moves to the position where the LDE lamp beads are to be picked up, the second cylinder 305 is controlled to make the lifting push rod 306 extend from the second cylinder 305, and the lifting plate 304 is pushed to move by the second cylinder 305, so that the lifting plate 304 follows the two lifting sliders 30 3 moves downward on the lifting guide rail 302, and the lifting plate 304 is assisted to rise and fall smoothly by two supporting slide bars 307, and the lifting plate 304 drives the picking tube 401 to fall, so that the suction cup 402 contacts the LED lamp bead, and the negative pressure generating device 404 is started. The negative pressure generating device 404 forms a negative pressure in the picking tube 401 through the air pipe 403, and then the LED lamp bead is sucked up by the suction cup 402. Through the negative pressure adsorption, damage to the LED lamp bead is avoided, and impurity particles on the lens of the LED lamp bead can be absorbed through adsorption, so as to avoid damage to the lens in the subsequent production links;

[0044] After picking up the LED lamp bead, the lifting push rod 306 is retracted into the second cylinder 305 by controlling the second cylinder 305, thereby driving the lifting plate 304 to rise, and driving the LED lamp bead adsorbed under the suction cup 402 to rise through the picking tube 401, and then controlling the first cylinder 206 to make the translation push rod 207 extend from the first cylinder 206, and driving the translation plate 205 to move away from the first cylinder 206 through the first cylinder 206, thereby driving the LED lamp bead to translate, and when it moves to the LED lamp bead placement position, the lifting plate 304 is driven to descend through the supporting slide bar 307, and after reaching the designated position, the negative pressure generating device 404 is controlled to stop working, so that the pressure in the picking tube 401 is normal, and the LED lamp bead can be smoothly put down at this time;

[0045] When the lifting plate 304 rises, the lifting rod 505 is driven to rise, and the lifting rod 505 is pressed down by the pressing plate 509, so that the top of the cleaning soft brush 514 can rotate and contact the bottom of the LDE lamp bead. At this time, the reset spring 508 is squeezed, and when the lifting plate 304 translates, the gear 511 translates with the lifting plate 304. When the gear 511 is engaged with the rack 502, the gear 511 is driven to rotate, so that the transmission shaft 510 rotates with the gear 511. When the transmission shaft 510 rotates, the rotating sleeve 503 is driven to rotate through the transmission belt 512. When the rotating sleeve 503 rotates, the limiting plate 504 inside it is driven to rotate at the same time, and the lifting slot 500 is inserted through the limiting plate 504. 6, the lifting rod 505 is driven to rotate synchronously with the rotating sleeve 503. When the lifting rod 505 rotates, the cleaning soft brush 514 is driven to rotate through the rotating plate 513. The bottom of the LED lamp bead is cleaned by the rotating cleaning soft brush 514 to avoid impurities adhering to the welding feet of the LED lamp bead, which may cause unstable welding during welding. When the translation of the lifting plate 304 is completed, the lifting rod 505 stops rotating, and the rotating plate 513 rotates away from the lifting rod 505 to the side away from the LED lamp bead. Thereafter, when the lifting plate 304 descends, the elastic force of the reset spring 508 causes the lifting rod 505 to drive the rotating plate 513 to rise and reset, so that the LED lamp bead can be put down smoothly.
