Abstract

A split lens assembly module, comprising: a focusing mechanism; and a lens assembly, wherein the lens assembly comprises at least two optical lenses, at least one lens barrel member and a bearing structure, each of the at least one lens barrel member holds at least one optical lens to form at least one to-be-adjusted lens assembly, the bearing structure holds at least one optical lens to form a fixing lens assembly, the to-be-adjusted lens assembly is pre-assembled on the fixing lens assembly, the to-be-adjusted lens assembly is suitable for being adjusted relative to an assembly position of the fixing lens assembly, the fixing lens assembly is mounted inside the focusing mechanism through the bearing structure, and moves as the focusing mechanism is powered on, which is suitable for focusing.

First claim

What is claimed is:

1. A split lens assembly module, comprising:
a focusing mechanism; and
a lens assembly, wherein the lens assembly comprises at least two optical lenses, at least one lens barrel member and a bearing structure, each of the at least one lens barrel member holds at least one optical lens to form at least one to-be-adjusted lens assembly, the bearing structure holds at least one optical lens to form a fixing lens assembly, the to-be-adjusted lens assembly is pre-assembled on the fixing lens assembly by glue to realize a pre-assembly of the to-be-adjusted lens assembly and the fixing lens assembly, the to-be-adjusted lens assembly is suitable for being adjusted relative to an assembly position of the fixing lens assembly, the bearing structure and the focusing mechanism are formed to be one body, and the fixing lens assembly is mounted inside the focusing mechanism through the bearing structure, and moves as the focusing mechanism is powered on, which is suitable for focusing,
wherein the glue used in the pre-assembly is a mixed adhesive of a UV adhesive and a thermosetting adhesive, the glue is semi-cured by ultraviolet exposure to realize the pre-assembly, in the pre-assembly the to-be-adjusted lens assembly is adjustable relative to the assembly position of the fixing lens assembly by the semi-cured glue, wherein the semi-cured glue is completely cured by a baking treatment to fix the entire split lens assembly module.

2. The split lens assembly module according to claim 1 , wherein a bottom end surface of the lens barrel member is pre-assembled on a top end surface of the bearing structure by the glue to realize the pre-assembly of the to-be-adjusted lens assembly and the fixing lens assembly.

3. The split lens assembly module according to claim 1 , wherein the bearing structure has at least one adjustment channel, the adjustment channel connects an internal space of the bearing structure to an external environment, the adjustment channel corresponds to the at least one optical lens of the at least one to-be-adjusted lens assembly.

4. The split lens assembly module according to claim 1 , wherein an assembly position of the to-be-adjusted lens assembly is suitable for being adjusted in at least one direction.

5. The split lens assembly module according to claim 1 , wherein an assembly position of the to-be-adjusted lens assembly is suitable for being adjusted in at least one direction.

6. The split lens assembly module according to claim 1 , wherein the focusing mechanism is suitable for being selected from a voice coil motor, a piezoelectric ceramic motor or a liquid crystal motor.

7. The split lens assembly module according to claim 1 , wherein the bearing structure is mounted inside the focusing mechanism and moves along the focusing mechanism.

8. The split lens assembly module according to claim 6 , wherein the bearing structure is mounted inside the focusing mechanism and moves along the focusing mechanism.

9. The split lens assembly module according to claim 7 , wherein a top end surface of the bearing structure is higher than a top end surface of the focusing mechanism.

10. The split lens assembly module according to claim 7 , wherein one optical lens is fixed in an internal space of the lens barrel member, and three optical lenses are fixed in an internal space of the bearing structure along a height direction of the bearing structure.

11. The split lens assembly module according to claim 5 , wherein the assembly position of the to-be-adjusted lens assembly is suitable for being adjusted in six directions.
