Technical Field
[0001] This utility model relates to the field of LED strip adhesive application technology, and in particular to an LED strip adhesive application mechanism. Background Technology
[0002] In the production process of products such as LCD monitors and LCD panels, thermally conductive adhesive strips need to be applied to the edge of the light guide plate before assembly to protect the light strips, improve their heat dissipation capacity, and increase their service life.
[0003] Traditional LED strip tape application relies on manual application, involving peeling the tape from the release film and attaching it to the strip before assembling it with the backlight module. However, LED strips are typically made of soft materials and are long and narrow. Manual operation makes it difficult to guarantee precise adhesion; moreover, the tape is prone to wrinkling during the application process, leading to inconsistent adhesion quality. Furthermore, manual application is physically demanding, causing employee fatigue, making it difficult to control production efficiency, and resulting in high labor costs. Therefore, achieving efficient tape-to-LED strip adhesion and improving the stability of the assembly process are issues that those skilled in the art need to consider. Utility Model Content

[0016] The present invention will be further described in detail below with reference to specific embodiments: like Figures 1-9 As shown, this utility model is applied to the bonding of adhesive strips and LED strips. After the protective film of the adhesive strip is removed, it is placed with the adhesive side down on the first carrier plate. The first transfer component picks up the adhesive strip and transfers it to the assembly station, where it is bonded and assembled with the LED strip. When the assembled LED strip is transferred to the unloading station, it is transferred to the second carrier plate by the second suction cup of the second transfer device. After a preset number of LED strips are placed on the trays on the second carrier plate, they are transferred to the fifth carrier plate by the third suction cup of the second transfer component for unloading. The LED strips are manually loaded at the loading station and placed on the third carrier plate. When the LED strip moves with the turntable to the positioning station, it is positioned by the positioning device. When it moves to the assembly station, it is assembled with the adhesive strip. When it moves to the unloading station, it is unloaded. Empty trays are stored in the hopper component. When the trays on the second carrier plate are full and transferred away, the third transfer component transfers the empty trays from the hopper to the second carrier plate. Specifically: A light strip adhesive application mechanism includes a loading mechanism 2, an assembly mechanism 3, and an unloading mechanism 4, all mounted on a first transfer component frame 1.
[0017] The feeding mechanism 2 includes a first carrier plate 21 for placing adhesive strips. The first carrier plate 21 has multiple through-holes 211, and a first lifting device 22 with a push rod 221 is located below it. In this embodiment, the adhesive strip is placed on the first carrier plate 21 after being peeled off in the previous process, with the adhesive side facing down. When the first transfer component 31 transfers the adhesive strip, the first suction cup 311 picks up the adhesive strip while the first lifting device 22 drives the push rod 221 to lift the adhesive strip upwards, causing it to detach from the surface of the first carrier plate 21, facilitating stable suction by the first suction cup 311. The first lifting device 22 can be a cylinder, a motor, or other device capable of driving linear motion. The first grooves 211 not only provide sufficient space for the push rod 221 to move but also reduce the contact area between the adhesive strip and the surface of the first carrier plate 21, preventing the adhesive strip from sticking too tightly to the first carrier plate 21.
[0018] The assembly mechanism 3 includes a first transfer assembly 31 and a turntable assembly 32. The first transfer assembly 31 includes a robotic arm 312 and a first suction cup 311 connected to the robotic arm 312. The robotic arm 312 can drive the first suction cup 311 to move, and the first suction cup 311 can pick up the adhesive strip on the first carrier plate 21 and transfer it to the assembly station.
[0019] The turntable assembly 32 includes a loading station 32a for feeding LED strips, a positioning station 32b for positioning the LED strips, an assembly station 32c for assembling adhesive strips, and a unloading station 32d. Each station has a corresponding third carrier plate 33 that can support the LED strip. The third carrier plate 33 is a long plate structure with multiple mounting ends 331 along its edge, and a push groove 332 is formed between two adjacent mounting ends 331. A limiting plate 333 is also provided on the upper end of the third carrier plate 33. The LED strip is placed on the mounting end 331, with one side of its width direction abutting against the limiting plate 333, and at least a portion of its side away from the limiting plate 333 overlapping the push groove 332.
[0020] A positioning device 34 is provided at the positioning station 32b. The positioning device 34 includes a push tooth 341 and a first driving device 342 connected to the push tooth 341. The first driving device 342 drives the positioning push tooth 341 to extend into the push groove 332 to abut against the light strip, so that the light strip abuts against the limiting plate 333.
[0021] In this embodiment, at the loading station 32a, a worker places the light strip onto the third carrier plate 33. When the light strip rotates with the turntable assembly 32 to the positioning station 32b, the first driving device 342 drives the pusher tooth 341 to extend into the pusher groove 332. The end of the pusher tooth 341 abuts against the side of the light strip away from the limiting plate 333, so that the side of the light strip close to the limiting plate 333 abuts against the limiting plate 333, completing the positioning of the light strip. Afterward, when the turntable assembly 32 rotates to the assembly station 32c, the first transfer assembly 31 drives the tape to be bonded and assembled with the light strip. When the bonded light strip rotates to the unloading station 32d, it is picked up by the second transfer assembly 41 and transferred to the second carrier plate 42 for unloading.
[0022] A first vision device 5 is installed between the feeding mechanism 2 and the assembly mechanism 3. A second vision device 6 is installed above the assembly station 32c. When the first transfer component 31 drives the adhesive strip to transfer, it stops directly above the first vision device 5, where the first vision device 5 collects the position information of the adhesive strip. When the light strip rotates with the turntable component 32 to the assembly station 32c, the second vision device 6 collects the position information of the light strip. The position information of the two devices is combined to ensure the stability of the adhesive strip and light strip bonding assembly.
[0023] The unloading mechanism 4 includes a second transfer assembly 41 and a second carrier plate 42. The second transfer assembly 41 includes a second suction cup 411 and a third suction cup 412. The second suction cup 411 picks up the light strip at the unloading station 32d and transfers it to the tray on the second carrier plate 42; the third suction cup 412 picks up the tray on the second carrier plate 42 and transfers it to the fifth carrier plate 43.
[0024] The feeding mechanism 4 also includes a hopper assembly 44 for storing material trays and a third transfer assembly 45 for moving the material trays in the hopper assembly 44 to the second carrier plate 42. The hopper assembly 44 includes a fourth carrier plate 441, a third lifting device 442 disposed at the lower end of the fourth carrier plate 441, and a plurality of positioning rods 443 that are vertically arranged and penetrate through the fourth carrier plate 441 at their upper ends.
[0025] In this embodiment, the tray is placed on the fourth carrier plate 441 and positioned between multiple positioning rods 443, which then position it. After the third transfer assembly 45 removes a tray from the hopper assembly 44, the third lifting device 442 drives the fourth carrier plate 441 to move vertically upward a distance equal to the thickness of one tray, so that the third transfer assembly 45 can remove the tray again.
[0026] When the number of LED strips placed on the tray on the second carrier plate 42 reaches the preset number, the third suction cup 412 picks up the tray and transfers it to the fifth carrier plate 43 under the drive of the second transfer component 41.
