Description

Technical Field

[0002] LED light strip refers to LEDs assembled on a strip-shaped FPC or PCB hard board. It is named because its product shape is like a strip. It has gradually emerged in various decoration industries because of its long service life, energy saving and green environmental protection. During the processing of LED light strips, it is necessary to stick tape on the back of the light strip.

[0003] For example, a gluing machine provided by announcement number CN118850862A includes a machine for gluing and cutting materials, and includes a tape pulling mechanism, a vacuum adsorption mechanism, a cutting mechanism and a transport mechanism. The tape pulling mechanism includes a rotating mechanism and a glue material, and the glue material is detachably mounted on the rotating mechanism so that the rotating mechanism can drive the glue material to rotate; the vacuum adsorption mechanism is used to adsorb the glue material; the cutting mechanism is used to cut the material after gluing; and the transport mechanism is used to transport the material to the cutting mechanism via the vacuum adsorption mechanism. The tape is adhered to the end of the light strip, and the light strip after gluing is pulled to the cutting mechanism via the transport mechanism, so that the light strip and the tape are automatically adhered. When the cutting mechanism cuts part of the light strip after gluing, the vacuum adsorption mechanism adsorbs the tape, thereby adsorbing the light strip after gluing, and the remaining light strip continues to be pulled to the cutting mechanism via the transport mechanism, and there is no need to manually re-adhere the tape to the end of the light strip, which saves time, improves the efficiency of gluing, and improves economic benefits.
