Terminal device with camera module having optical lens and method for assembling same

An assembling method for optical camera lens, wherein the method comprises:

• pre-positioning a first lens component and a second lens component so that a first lens sheet group and a second lens sheet group constitute an imageable optical system, wherein the first lens component comprises the first lens sheet group, the second lens component comprises the second lens sheet group, the second lens sheet group comprises at least one free-form lens, and
• the second lens component has a first side and a second side opposite to the first side, and
• wherein the at least one free-form lens is adapted to deflect incident light toward the second side, so that an imaging plane of the optical system is offset toward the second side;
• performing active alignment on the first lens component and the second lens component, wherein
• the active alignment is to adjust a relative position of the first lens component and the second lens component based on an actual imaging result of the optical system;
• and
• bonding the first lens component and the second lens component, so that the relative position of the two is maintained at a relative position determined by active alignment.

An assembling method for camera module, wherein the method comprises:

• pre-positioning a first lens component, a second lens component and a photosensitive assembly so that a first lens sheet group and a second lens sheet group constitute an imageable optical system, and a photosensitive chip can receive an image formed by the optical system, wherein
• the first lens component comprises the first lens sheet group, the second lens component comprises the second lens sheet group, the second lens sheet group comprises at least one free-form lens, the second lens component has a first side and a second side opposite to the first side,
• and the photosensitive assembly comprises the photosensitive chip, and wherein the at least one free-form lens is adapted to deflect incident light toward the second side, so that an imaging plane of the optical system is offset toward the second side;
• performing active alignment on the first lens component, the second lens component and the photosensitive assembly, wherein the active alignment is to adjust a relative position of the first lens component and the second lens component, and a relative position of the second lens component and the photosensitive assembly based on an actual imaging result of the optical system;
• and
• bonding the first lens component and the second lens component, and bonding the second lens component and the photosensitive assembly, so that the relative positions of the first lens component, the second lens component, and the photosensitive assembly are all maintained at relative positions determined by active alignment.
