1. A method for manufacturing a multi-lens assembly, comprising:
connecting a first lens and a second lens by using first glue, and the second lens is connected to a motor;
providing an air escape hole, wherein the air escape hole is located between the first lens and the second lens;
curing the first glue through baking, so that expanded gas generated in the baking of the first glue is discharged from the air escape hole; and
after the first glue is completely cured, sealing the air escape hole by using second glue that can be completely cured without baking,
wherein an upper surface of the second lens is lower than an upper surface of the motor, and the second glue is applied from a gap between the first lens and a motor carrier of the motor, to seal the air escape hole, and the second glue connects the first lens, the second lens, and the motor.
