[0057] The mobile phone screen is transported to the transport tray and the conveyor belt through the feeding pipeline 2, and then the mobile phone screen is transported to the first material platform 502 or the second material platform 503 by the four-axis robot 6. Through alternating transportation, the transportation efficiency is improved. The mobile phone screen is transported from the first material platform 502 or the second material platform 503 to the turntable mechanism 7 by the four-axis robot 6. After the code scanning and positioning are completed, it goes to the dispensing pipeline 3 for dispensing. At this time, the position of the mobile phone screen is adjusted by the adjustment mechanism 703 and the flipping mechanism 8 to facilitate entry into the dispensing pipeline 3.

[0058] The mobile phone screen is adsorbed by the dispensing platform 301, and then rotated 90° first by the second rotating motor 303, and then rotated by the first rotating motor 302, so that the dispensing needle 304 can dispense glue on the two side keys of the mobile phone screen respectively. After completion, the second rotating motor 303 rotates back to the original position, and the mobile phone screen is brought back to the linear transport line 9 by the first sliding table 306. Then, the four-axis robot 6 discharges the mobile phone screen after dispensing in the same way on the discharging pipeline 4.
