The number of cameras of a mobile phone on the market is more and more, the number of holes formed by camera lenses and back glue is more and more, and the back glue design of a plurality of camera holes is mostly the back glue design shown in fig. 1, and the back glue design comprises a core separating film 10, back glue 20, a shell 30 and a camera 40.
The disadvantages of the existing structural design are analyzed as follows:
1. in the existing design, as shown in fig. 2, a tearing handle 101 for a core-separating film 10 of a back adhesive 20 exists, and a certain stress exists in the core-separating film 10, which causes the core-separating film 10 to separate from the back adhesive 20 as shown in a circle position in the figure, thereby causing the influence on the adhesiveness of the back adhesive due to dust.
2. The tear handle 101 is also present away from the core film 10 as shown in fig. 3, the tear handle 101 being folded within the chassis 30. It can be seen from fig. 1 that to tear off the core separating film 10, all the core separating films on the left side are torn and separated to completely tear off the centrifugal force, and the back adhesive has strong viscosity, so that the core separating films are not easily separated, and the production efficiency is affected.

Detailed Description
The invention is further described in the following description and embodiments with reference to the drawings.
As shown in fig. 4 to 6, a method for preparing a back adhesive for a lens of a camera comprises the following steps:
s1, preparing three cutting dies, namely a first cutting die 11, a second cutting die 12 and a third cutting die 13, wherein the first cutting die 11, the second cutting die 12 and the third cutting die 13 are respectively provided with a cutting die positioning column 14, the first cutting die 11 is provided with a first cutting edge 111 for punching a camera hole, the second cutting die 12 is provided with a second cutting edge 121 for punching a tearing handle in the camera hole, the second cutting edge 121 is provided with a cutting trace cutting edge 122, and the third cutting die 13 is provided with a third cutting edge 131 for punching a shape.
S2, punching a camera hole 5, installing the first cutting die 11 on a die-cutting machine, placing the lower release core film 2 on a machine table of the die-cutting machine, then flatly paving the back adhesive 3 on the lower release core film 2, and punching the back adhesive 3 and the lower release core film 2 by using the first cutting die 11 so as to form the camera hole 5.
