Focus-fixed camera module

摘要

The present disclosure relates to a focus-free camera module minimized in height deviation of depth of focus, the focus-fixed focus-free camera module including: an image sensor; a PCB (Printed Circuit Board) mounted with the image sensor; a barrel mounted at an upper surface of the image sensor and accommodated with a lens therein; a holder attached to an upper surface of the PCB to accommodate the barrel; and adhesive means adhering an outer circumference of the barrel to an inner circumference of the holder, such that no height deviation in depth of focus is generated by adhesive structure in which a bottom distal end surface of the barrel is tightly adhered to an upper surface of an image sensor side without any separate medium.

主权项

1. A camera module, the camera module comprising:
an image sensor; a PCB (Printed Circuit Board) mounted with the image sensor; a barrel fixed at an upper surface of the image sensor and accommodated with a lens therein; and a holder attached to an upper surface of the PCB to accommodate the barrel; wherein the barrel is configured such that an inner circumference of the holder is adhered to an outer circumference of the barrel by adhesive means to allow the barrel to be fixed on the upper surface of the image sensor, wherein the barrel is taller than the holder, and wherein the adhesive means is injected on an exposed area of the outer circumference of the barrel after mounting of the barrel and holder.
