The unwinding roll 42 has a certain rotational damping so that the material strip can be straightened. The unwinding roll 42 unwinds the material strip via the guide roller 45 and unwinds it onto the guide plate 43. After the material strip passes through the separation slope, the adhesive film will be separated from the material strip and moved to the receiving plate 51. The receiving plate 51 is coated with an anti-stick coating to prevent the adhesive film from sticking to its surface, which facilitates the subsequent removal of the adhesive film.

[0051] Usage process

[0052] The material roll loaded with the film is placed on the unwinding roll 42, and the receiving roll 44 adopts the existing technology to provide rotational tension. The unwinding roll 42 has a certain rotational damping so that the material strip can be straightened. The unwinding roll 42 unwinds the material strip and unwinds it to the guide plate 43 via the guide roller 45. After the material strip passes through the separation slope, the film will be separated from the material strip and moved to the receiving plate 51. The receiving plate 51 is coated with an anti-stick coating to prevent the film from sticking to its surface, which is convenient for subsequent material collection of the film. The material roll provides rotational tension so that the material strip after separation of the film is rewound through the receiving roll 44, thereby completing the rapid feeding of the film one by one. The running directions of the horizontal linear module 12, the longitudinal linear module 14, and the lifting linear module 16 are perpendicular to each other to form a three-axis linear module, which drives the material picking gripper 2 to move to the receiving plate 51 At the top, the lifting cylinder 61 is used to drive the material picking rack 23 to move downward along the slide rail 6 so that the material picking groove 252 on the vacuum suction nozzle 25 is covered on the film. At the same time, the suction hole generates negative pressure to suck the film. The material picking rod 24 is provided with an air valve connected to the suction hole, and the air valve is connected to the vacuum generating device. After the multiple material picking components 22 on the material picking gripper 2 grab the film one by one, they are moved to the top of the detection mechanism 3 under the drive of the three-axis linear module. The rotator drives the material picking nozzle to rotate so that the detection camera can more comprehensively detect the film, and at the same time adjust the film to a suitable pasting state. After the detection camera takes a picture and detects the film sucked by the material picking gripper 2, it is driven by the three-axis linear module to move the film that has completed the inspection and adjustment to the product for pasting, thereby completing the rapid loading of the film and improving the processing efficiency.
