Detailed Description

The present invention will be further described with reference to specific embodiments for the purpose of facilitating an understanding of technical means, characteristics of creation, objectives and functions realized by the present invention, but the following embodiments are only preferred embodiments of the present invention, and are not intended to be exhaustive. Based on the embodiments in the implementation, other embodiments obtained by those skilled in the art without any creative efforts belong to the protection scope of the present invention. The experimental methods in the following examples are conventional methods unless otherwise specified, and materials, reagents and the like used in the following examples are commercially available unless otherwise specified.

Example (b):

referring to fig. 1-4, the anti-collision device after the PCB is laminated comprises a PCB 1 and anti-collision cotton 2, wherein the inner wall of the anti-collision cotton 2 is wrapped by a rubber block 4, a plurality of groups of supporting columns 7 are hot-melted and attached to the surface of the rubber block 4, the plurality of groups of supporting columns 7 penetrate through the surface of the anti-collision cotton 2, a plurality of groups of anti-slip blocks 8 are hot-melted and attached to the surfaces of the plurality of groups of supporting columns 7, and the PCB 1 is attached to the surfaces of the anti-slip blocks 8;

when using the anticollision cotton 2, earlier with 2 suit of anticollision cotton on the 4 surfaces of rubber block, and the pillar 7 of 4 surface hot melt laminating of rubber block passes rubber block 4, make the non slipping spur 8 of 7 tip hot melt laminating of pillar be higher than 2 surface 2-3cm of anticollision cotton, when placing the anticollision cotton 2, through the intensity of rubber block 4 increase anticollision cotton 2, after PCB board 1 was placed on anticollision cotton 2, PCB board 1 was laminated with the 8 surfaces of non slipping spur earlier, non slipping spur 8 increases the frictional force of PCB board 1 and anticollision cotton 2, avoid PCB board 1 to slide in the 2 surfaces of anticollision cotton.
