[0019] A COB packaging process for LED light strips, using the above-mentioned COB packaging device for LED light strips, specifically comprises the following steps: Step 1: Place the prepared hot melt adhesive into the container and turn on the heating component to prevent the hot melt adhesive from solidifying; Step 2: Place the LED light strip with the chip on the conveyor belt surface, and start the drive assembly to drive the LED light strip to move; Step 3: The driving clamp slightly squeezes the LED light strip to fix it, and the operation of the conveyor belt can no longer drive the LED light strip to move; Step 4: Drive the glue dispenser to apply hot melt glue to the chip on the surface of the LED light strip; Step 5: Use a brush roller to spread the glue evenly to make the glue application area larger and the adhesion stronger; Step 6: Place the glue-dispensed LED light strip into the drying device to dry the glue on the surface of the LED light strip.

[0020] Working principle: First, place the LED light strip with the chip embedded on the surface on the surface of the transmission belt 703, then turn on the first drive motor 5, the second drive motor 7 and the heating assembly on the inner wall of the glue barrel 4, the second drive motor 7 drives the transmission roller 702 to rotate, the rotation of the transmission roller 702 will drive another transmission roller 702 to rotate through the transmission belt 703, thereby driving the LED light strip to move inside the groove 101, the first drive motor 5 drives the drive shaft 501, the drive bevel gear 502 and the half-scale wheel 503 to rotate, when the half-scale wheel 503 rotates, it drives the return groove plate 504 to do a reciprocating linear motion left and right, one end of the push-pull rod 505 is fixedly installed with a piston plate 510, when the return groove plate 504 moves, it drives the push-pull rod 505 to move inside the glue extraction bin 509 , thereby driving the piston plate 510 to move inside the glue extraction bin 509. A first one-way valve 511 and a second one-way valve 512 are provided on both sides of the glue extraction bin 509. When the piston plate 510 moves to the left inside the glue extraction bin 509, the glue inside the glue barrel 4 can be drawn into the glue extraction bin 509 through the glue extraction pipe 513 through the first one-way valve 511. When the piston plate 510 moves to the right inside the glue extraction bin 509, the piston plate 510 transfers the glue to the inside of the temperature recovery component 6 through the second one-way valve 512 and the glue outlet pipe 514. Subsequently, the glue inside the temperature recovery component 6 gradually increases, and the glue will be transferred to the inside of the glue dispensing device 603 through the glue discharge pipe 601, and then the chip on the LED lamp board is glued through the glue dispensing head 604.

[0021] The driving bevel gear 502 drives the driven bevel gear 506 to rotate, thereby driving the reciprocating screw rod 507 to rotate, thereby driving the sleeve rod 508 to move back and forth on the surface of the reciprocating screw rod 507, thereby driving the slider 518 to slide inside the slide groove 103. Here, the slider 518 plays a role in limiting the push plate 515 to prevent the sleeve rod 508 from driving the push plate 515 to move too far toward the LED light strip, thereby increasing the pressure on the LED light strip and squeezing the chip out of the LED light strip. When the push plate 515 moves, it clamps and aligns the LED light strip, so that the LED light strip is in a straight state and close to the inner wall of the groove 101, and when the push plate 515 clamps the LED light strip, the push plate 515 The force of clamping the LED light strip is greater than the friction between the transmission belt 703 and the LED light strip, so the transmission belt 703 at this time cannot drive the LED light strip to continue moving. When the LED light strip is clamped, the glue dispensing device 603 starts to dispense glue. When the push plate 515 retracts, the transmission belt 703 continues to drive the LED light strip to move. When the LED light strip moves to the position corresponding to the smoothing roller 517, the push plate 515 clamps the LED light strip again. At the same time, when the push plate 515 moves, it will drive the mounting plate 516 to move, thereby driving the smoothing roller 517 to roll on the surface of the LED light strip, evenly spread the glue on the surface of the LED light board, increase the glue coating range, and make the chip and the LED light board more firmly connected.

[0022] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
