Light guide plate FPC assembling device in mobile phone backlight plate processing process

Abstract

The invention discloses a light guide plate FPC (Flexible Printed Circuit) assembly device in a mobile phone backlight plate processing process, which relates to the technical field of FPC assembly and comprises a belt conveyor I, a belt conveyor II, a mounting plate I, a mounting plate III, a film tearing mechanism for tearing release paper and a pasting mechanism for assisting pasting. A press-fitting mechanism used for pressing the flexible circuit board is arranged above the first belt conveyor. The push-out length of a piston rod is controlled through a stroke air cylinder, a first inclined block downwards extrudes and pushes an abutting plate, finally, a pressing roller tightly presses a light guide plate, a second inclined block downwards extrudes and pushes an abutting rod, a first suction cup adsorbs release paper, the stroke air cylinder is started to retract the half-stroke piston rod, and at the moment, the second inclined block relieves abutting against the abutting rod; when the stroke air cylinder retracts the piston rod, the first belt conveyor is started synchronously, one end of the release paper is fixed by the first suction cup, and the release paper on the outer wall of the light guide plate is torn off quickly and reliably.

Description

technical field [0001] The invention relates to the technical field of FPC assembly, in particular to an FPC assembly device of a light guide plate during the processing of a backlight plate of a mobile phone. Background technique [0002] During the processing of the mobile phone backlight board, when assembling the FPC assembly on the light guide plate, it is necessary to tear off the lamp glue release paper, and then paste the FPC assembly on the corresponding position on the light guide plate (generally provided with grooves), in order to ensure The sticking is firm and generally needs to be pressed at the sticking position. If the gripper robot in the prior art is used to operate, at least two machines are required, one of which is used to tear off the release paper of the lamp glue, and the other is used to grasp the FPC group. products, while the cost of two robots is higher. [0003] In view of the above problems, the Chinese Patent Application Publication No. CN208...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a light guide plate FPC assembly device in the process of mobile phone backlight plate processing, to solve the problem that the adhesion between the light guide plate and the outer wall release paper in the prior art will change, and when the release paper is torn off, The guide paper at one end of the release paper is easily torn, resulting in the failure of the release paper torn off, which affects the technical problem of the tear-off efficiency of the light guide plate release paper
