The diameter of the linear bearing 8062 is larger than that of the second through hole 80121, and a lifting area 809 of the second lifting device 808 is formed between the bottom of the linear bearing 8062 and the upper surface of the sixth fixing frame 8012. The sixth air cylinder 8042 controls the second lifting device 808 to lift and lower the sixth fixing frame 8012 in the lifting area 809.
After the dedusted single film material enters the film lifting mechanism 8, the film lifting device 801 is moved to the vicinity of the starting end of the single film material through the fifth air cylinder 8041, then the film sticking roller 8011 is controlled by the sixth air cylinder 8042 to press the single film material and then loosen the single film material, and then the fifth fixing frame 802 is controlled by the second lead screw module 803 to drive the film lifting device 801 to move in the horizontal direction; because the adhesive film roller 8011 with the adhesive silica gel easily generates static electricity with the FPC covering film under the action of pressure, the FPC covering film is easily separated from the base paper, the static electricity action is still existed when the FPC covering film is loosened, so that the second screw rod module 803 can drive the FPC covering film attached to the adhesive film roller 8011 to move in the opposite direction, but the adhesive film roller 8011 does not extrude the FPC covering film any more, therefore, the static electricity action can be weakened when the second screw rod module 803 moves to a certain distance, the FPC covering film is not attached to the adhesive film roller 8011 any more, and the damage to the FPC covering film when the film forming device 801 is withdrawn is avoided.
In summary, the automatic film tearing of the roll material can be completed by the automatic unwinding mechanism 1, the dust sticking mechanism 2, the backing paper pulling mechanism 3, the automatic winding mechanism 4, the cutting mechanism 5 and the automatic film pulling mechanism 6, and the automatic film tearing of a single FPC coverlay material can be completed by the film storage bin 7, the dust sticking mechanism 2, the film lifting mechanism 8, the backing paper pulling mechanism 3 and the automatic film pulling mechanism 6. After the roll material enters the dust sticking mechanism 2 through the transfer platform, the base paper is automatically recovered through the base paper pulling mechanism 3, and the FPC cover film is cut through the cutting mechanism 5 and then pulled through the automatic film pulling mechanism 6; the single film material is conveyed to the dust sticking mechanism 2 through the film storage bin 7, is subjected to film lifting through the film lifting mechanism 8, is cut through the cutting mechanism 5 and then enters the automatic film pulling mechanism 6; therefore, the automatic film tearing mechanism for the FPC coverlay can not only automatically tear a film for a rolled material, but also automatically tear a single FPC coverlay material.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the scope of the present invention, which is intended to cover any modifications, equivalents, improvements, etc. within the spirit and scope of the present invention.
