[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4The utility model provides a technical solution: a reinforcing steel sheet that is easy to install, including a patch 1, with films 2 connected on both sides of the patch 1, the upper surface of the film 2 is a glue surface 3, the width of the film 2 is longer than the thickness of the patch 1, the upper surface of the patch 1 is provided with thermosetting glue, and the lower surface of the patch 1 is connected with a self-adhesive 4, the two ends of the self-adhesive 4 extend toward the film 2, the length of the self-adhesive 4 is longer than the distance between the two films 2, the two ends of the self-adhesive 4 are not sticky, the side lengths of the film 2 and the patch 1 are the same, and the patch 1 is made of stainless steel.

[0025] During operation, the upper surface of the patch 1 is attached to the corresponding position on the FPC board, one end of the self-adhesive tape 4 is pulled upward to drive the corresponding film 2 to bend upward, and the film 2 is pressed toward the patch 1 to make the adhesive surface 3 adhere to the side of the patch 1, and the film 2 adhere to the side of the patch 1. At this time, there is still a part of the film 2 and the adhesive surface 3 that is not adhered to the patch 1, and this part is higher than the patch 1 and the FPC board. This part is bent toward the patch 1 to make the adhesive surface 3 adhere to the side of the surface of the FPC board, so that the film 2 adheres to the side of the surface of the FPC board, and the other end of the self-adhesive tape 4 is pulled upward and the above operation is repeated, so that the films 2 on both sides can be connected to the two sides of the surface of the FPC board respectively, so that the patch 1 and the FPC board are initially adhered and fixed, and then the thermosetting adhesive is melted by hot pressing, so that the patch 1 is installed on the FPC board.

[0026] See also Figure 1-4 The utility model provides a technical solution: both sides of the lower surface of the adhesive label 4 are connected with rubber sheets 6.

[0027] During operation, the thickness of both sides of the adhesive tape 4 can be increased by setting the rubber sheet 6, so that the two ends of the adhesive tape 4 can be easily held by hand, thereby pulling up the two ends of the adhesive tape 4.

[0028] See also Figure 1-4 The utility model provides a technical solution: the film 2 is made of polyimide.

[0029] When working, the polyimide film 2 can provide good waterproof and wear-resistant properties for the FPC flexible circuit board.

[0030] See also Figure 1-4 The utility model provides a technical solution: a rubber strip 5 is connected to the upper surface of the film 2, the distance between the rubber strip 5 and the patch 1 is the same as the thickness of the patch 1, and the rubber strip 5 is parallel to the side of the patch 1.

[0031] During operation, after the film 2 is adhered to the side of the patch 1, the adhesive strip 5 will stay at the outer side of the upper surface of the patch 1, and the adhesive strip 5 is in contact with the surface of the patch 1. The adhesive strip 5 can play a limiting role to prevent the film 2 from deflecting when it is bent, which is conducive to the adhesion of the film 2 to the outer side of the FPC board surface.

[0032] See also Figure 1-4 The utility model provides a technical solution: the outer surface of the rubber sheet 6 is provided with anti-slip textures.

[0033] During operation, the anti-skid pattern can enhance the friction force on the surface of the rubber sheet 6 , making it easier to hold the rubber sheet 6 by hand.

[0034] See also Figure 1-4 The utility model provides a technical solution: the adhesive strip 5 is made of hot melt adhesive and is semi-cylindrical.

[0035] During operation, the adhesive strip 5 will melt during the subsequent hot pressing, so that the adhesive strip 5 can act as an adhesive, thereby improving the connection stability between the film 2 and the FPC board.

[0036] See also Figure 1-4 The utility model provides a technical solution: the length of the rubber strip 5 is smaller than the length of the film 2 .

[0037] During operation, the adhesive strip 5 is set shorter so that it is not easy to overflow from between the film 2 and the FPC board when the adhesive strip 5 melts.

[0038] In summary, the upper surface of the patch 1 is attached to the corresponding position on the FPC board, and one end of the adhesive 4 is pulled upward to drive the corresponding film 2 to bend upward. At the same time, the adhesive strip 5 will stay at the outer position of the upper surface of the patch 1, and the adhesive strip 5 is attached to the surface of the patch 1. The adhesive strip 5 can play a limiting role to prevent the film 2 from deflecting during subsequent bending. The film 2 is pressed toward the patch 1 so that the adhesive surface 3 is adhered to the side of the patch 1, and the film 2 is adhered to the side of the patch 1. At this time, there is still a gap between the film 2 and the adhesive surface 3. Part of it is not adhered to patch 1, and this part is higher than patch 1 and FPC board. Bend this part toward patch 1 to make the adhesive surface 3 adhere to the side of the FPC board surface, so that the film 2 adheres to the side of the FPC board surface. Pull the other end of the adhesive 4 upward and repeat the above operation to connect the films 2 on both sides to the two sides of the FPC board surface respectively, so that patch 1 and FPC board are initially adhered and fixed. Subsequently, the thermosetting adhesive is melted by hot pressing to install patch 1 on the FPC board.
