Apparatus for attaching insulation tape on shield can for camera module}

The present invention relates to a device for attaching an insulating tape for a camera module shield can for attaching an insulating tape to an outer surface and an inner surface of the shield can for a camera module so that radio wave interference and a short circuit do not occur in the camera module.

In general, a camera module is a compact and lightweight camera that is mounted on portable electronic devices such as smartphones, tablets, and notebook computers, and refers to a product that is integrated to simplify assembly.

In general, these camera modules are connected to a main board on which various electronic devices are mounted to drive electronic devices, and in particular, electronic devices used in mobile communication terminals are composed of integrated modules, so they are exposed to severe radio interference. It is easy, and in this case, malfunctions of electronic devices occur.

A typical way to solve this problem is to use a shieldcase.

The shield can is a rectangular shield with an open bottom made of a metal plate or plastic with conductive metals (Fe, Cu, Ni, etc.) added, and is the same as a memory chip mounted on a printed circuit board (PCB) embedded in an electronic device. The electronic component is covered to block EMI (Electro Magnetic Interference) generated from the electronic component.

However, in order for the shield can to exhibit shielding performance, insulation treatment is required. Conventionally, a method of depositing insulating ink on the inner sidewalls and the bottom of the shield can has been used, but the shield can on which the insulating ink is deposited is applied to the electronic device. Insulation ink is peeled off or damaged by tweezers or electronic devices when attaching, and thus a short circuit may occur because insulation is not performed. In recent years, a method of attaching an insulating tape instead of the insulating ink is mainly adopted.

As a method of attaching an insulating tape, a device for attaching an insulating tape for a shield can for a camera module disclosed through Korean Patent Publication No. 10-1699360 and a method for attaching the same is known.

However, the above method follows the method of attaching the insulation tape to the inside of the narrow insertion grooves of the jig, and attaching the insulation tape to the shield can by applying heat and pressure after inserting the shield can into the insertion groove to which the insulation tape is attached. Therefore, it is difficult to perform the work and it takes a long work time, and there is a problem that it is difficult to implement a continuous process because the jig must be removed after the work is completed.

In particular, due to the characteristics of the camera module, it is sometimes necessary to attach insulating tape to both the inner and outer surfaces of the shield can. However, it is impossible to attach the insulating tape to the inner and outer surfaces of the shield can by the above method.
