One end of the label passes through the plurality of guide rollers 422 to the pressure plate 423, and then returns to the label wheel 421. The transfer mechanism 43 then includes a vacuum transfer head 431. The vacuum transfer head 431 is connected to a fourth lifting cylinder 432 and a second sliding cylinder 433, which are used to drive the vacuum transfer head 431 to the film-sticking mechanism 42 to tear off the label and then transfer it to the mobile phone screen 6 on the turntable mechanism 8.

[0077] Workflow

[0078] The loading assembly line 2 transports the mobile phone screen 6 to the loading mechanism 21 through the transport tray, and then the mobile phone screen 6 on the transport tray is transferred to the first material platform 71 and the second material platform 72 through the four-axis robot 5. The transportation efficiency is improved by the alternating transportation of the first material platform 71 and the second material platform 72. After arriving at the loading mechanism 21, the mobile phone screen 6 is transferred to the platform 816 through the four-axis robot 5, and then driven to rotate by the dividing turntable 81 of the turntable mechanism 8, the mobile phone screen 6 is respectively rotated from the positioning part 812 to the dust removal part, the code scanning part 813 and the film tearing part 811, and different operations are performed on different parts. At this time, the position of the mobile phone screen 6 on the platform 816 can be adjusted by the adjustment mechanism 83.

[0079] When the mobile phone screen 6 reaches the film tearing part 811, the mobile phone screen 6 is pressed against the platform 816 of the film tearing part 811 by the clamping component 221, and then the film on the circular hole is slid and torn off on the mobile phone screen 6 by the adhesive head 2221, and then it is rotated to the positioning part 812, and the mobile phone screen 6 with the film torn off on the positioning part 812 is transported to the straight transportation line 32 of the glue dispensing assembly line 3 by adsorption and flipping through the flipping mechanism 23, and then the mobile phone screen 6 is placed on the glue dispensing table 311 of the glue dispensing mechanism 31 by the four-axis robot 5 on the glue dispensing assembly line 3, and then the glue dispensing table 311 is driven to the bottom of the glue dispensing head 312 by the fourth slide 314, and the glue dispensing head 312 is driven to move for glue dispensing by the first moving module 316 and the second moving module 317. At the same time, in order to make the glue dispensing more accurate and smooth, a CCD positioning detection component 318 is also included for locating the glue dispensing position. A third rotating motor 313 is provided at the bottom of the dispensing table 311, which drives the dispensing table 311 to rotate 360° in the horizontal direction. That is, after the CCD positioning is completed, there is no need to move it again. The dispensing head 312 can directly cooperate with the third rotating motor 313, which is more accurate.

[0080] After the dispensing is completed, the mobile phone screen 6 slides to the straight transport line 32 through the fourth slide 314, and is transported to the unloading assembly line 4. The unloading assembly line 4 is similar to the loading assembly line 2 except for film tearing and film pasting. The mobile phone screen 6 on the dividing turntable 81 is labeled through the film pasting mechanism 42 and the transfer mechanism 43. Then, the unloading is performed through the first material table 71 and the second material table 72 of the unloading assembly line 4.
