[0001] The present disclosure relates to a camera module. Background Art

[0002] Due to the remarkable development of information and communication technology and semiconductor technology, the distribution and use of electronic devices are rapidly increasing. These electronic devices tend to provide various functions through convergence rather than staying in their own traditional fields.

[0003] Recently, cameras have been basically used in portable electronic devices such as smartphones, tablet PCs, and laptop computers and an auto focus (AF) function, an image stabilization function, a zoom function, etc. are added to the cameras of these portable electronic devices.

[0004] In the case where an adhesive such as epoxy resin is used to bond and fix the infrared filter of such a camera module and the sub-housing on which the infrared filter is mounted, gas is generated during curing. In order to exhaust the gas, a space for gas exhaust may be provided as a space engraved on the placement part of the sub-housing, and since the space may allow foreign matter to enter or a flare phenomenon may occur, there is a need for improvement.

[0005] The above information is presented as background information only to assist with understanding the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above may be applicable as prior art with respect to the present disclosure. Summary of the invention

[0048] The features of the examples described herein may be combined in various ways that will be apparent after understanding the present disclosure. In addition, although the examples described herein have various configurations, other configurations that will be apparent after understanding the present disclosure are also possible.

[0049] Furthermore, throughout the specification, the phrase “in a plan view” or “on a plane” means observing a target portion from the top, and the phrase “in a cross-sectional view” or “on a section” means observing a section formed by vertically cutting the target portion from the side.

[0050] refer to Figure 1 , a camera module 10 according to an embodiment will be described. Figure 1 is a schematic cross-sectional view of a camera module according to an embodiment.

[0051] First, refer to Figure 1 , the camera module 10 according to the embodiment may include a housing 100 , a lens barrel 200 , a lens driver 300 , a substrate 400 , an image sensor 500 , a sub housing 600 , and an infrared filter 700 .

[0052] The housing 100 may accommodate the lens barrel 200 and the lens driver 300. The housing 100 may have a polyhedral shape having a substantially quadrilateral (e.g., rectangular) cross section and a predetermined height. However, the shape of the housing 100 is not limited to a polyhedral shape having a quadrilateral (e.g., rectangular) cross section.

[0053] The lens barrel 200 may be a cylindrical shape with a hollow space to accommodate a plurality of lenses for imaging an object, and the plurality of lenses may be installed in the lens barrel 200 along the optical axis. A plurality of lenses may be provided in a desired number according to the design of the lens barrel 200, and the lenses may have the same or different optical properties such as refractive index. The lens barrel 200 may be moved in the optical axis direction or in a direction perpendicular to the optical axis by the driving torque of the lens driver 300 while being accommodated in the housing 100.

[0054] The lens driver 300 is a device configured to install and move the lens barrel 200, and may include an auto focus (AF) unit for adjusting the focus and an optical image stabilization (OIS) unit configured to compensate for hand shaking or shaking. For example, the lens driver 300 may adjust the focus or implement a zoom function by moving the lens barrel 200 in the optical axis direction (Z-axis direction in the drawing) using the AF unit, and may compensate for hand shaking or shaking during shooting by moving the lens barrel 200 in a direction perpendicular to the optical axis direction (X-axis direction or Y-axis direction in the drawing) using the OIS unit.

[0055] The substrate 400 may be electrically connected to the lens driver 300. The substrate 400 may be a printed circuit board.

[0056] The image sensor 500 may be mounted on the substrate 400. The image sensor 500 may be located below the lens barrel 200 along the optical axis direction. The image sensor 500 may convert light incident through the lens barrel 200 into an electrical signal. For example, the image sensor 500 may be a charge coupled device (CCD) or a complementary metal oxide semiconductor (CMOS). The electrical signal converted by the image sensor 500 may be output as an image through a display unit (not shown) of an electronic device equipped with the camera module 10. The image sensor 500 may be fixed to the substrate 400 and electrically connected to the substrate 400.

[0057] The sub-housing 600 and the infrared filter 700 mounted on the sub-housing 600 may be located between the lens barrel 200 and the substrate 400 on which the image sensor 500 is mounted. The infrared filter 700 may be arranged below the lens barrel 200 along the optical axis direction of the lens barrel 200. The infrared filter 700 may be located inside the sub-housing 600. The infrared filter 700 may be configured to block light of a specific wavelength. For example, the infrared filter 700 may be configured to block infrared rays. However, the light blocked by the infrared filter 700 is not limited to infrared rays.

[0058] The infrared filter 700 can be fixed using various methods. For example, the infrared filter 700 can be fixed by bonding with an ultraviolet (UV) curable adhesive material or a thermal curable adhesive material, and at this time, the adhesive material can be formed of an epoxy material. In addition, other available bonding means such as adhesive tape can also be used.

[0059] Thus, the housing 100 and the sub housing 600 may define an inner space configured to accommodate the lens barrel 200 , the lens driver 300 , or the image sensor 500 .

[0060] In the following, with Figure 1 Reference together Figures 2 to 6 , the sub housing 600 of the camera module 10 according to the present embodiment will be described in further detail. Figure 2 is a top plan view of a portion of a camera module according to an embodiment. Figure 3 is a perspective view of a portion of a camera module according to an embodiment.

[0061] Figure 4 A camera module according to an embodiment Figure 3 An enlarged perspective view of portion A shown in FIG.

[0062] Figure 5 It is shown along Figure 2A cross-sectional view of a camera module according to an embodiment, in which a filler material is not provided, taken along line VV′. Figure 6 It is shown along Figure 2 2 is a cross-sectional view of a portion of a camera module according to an embodiment, taken along line VV′.

[0063] The sub-housing 600 may have a rectangular planar shape. The sub-housing 600 may have an opening 603 at a central portion, and the image sensor 500 may be located in the opening 603 of the sub-housing 600. The opening 603 of the sub-housing 600 may also have a rectangular planar shape.

[0064] The sub housing 600 may have a step difference along the optical axis direction, and may include a frame portion 601 and a seating portion 602 which are sequentially connected.

[0065] The placement portion 602 may be disposed to surround an opening 603 at least partially overlapping the image sensor 500. The placement portion 602 may be located between the opening 603 and the frame portion 601. The infrared filter 700 may be accommodated and mounted on the placement portion 602. Along the optical axis direction, the height of the placement portion 602 may be lower than the height of the frame portion 601. The placement portion 602 may have a quadrilateral (e.g., rectangular) planar shape, but is not limited thereto.

[0066] The frame portion 601 may be supported by the substrate 400. The frame portion 601 may space the seating portion 602 apart from the substrate 400. The frame portion 601 may be located in an outer portion of the sub-housing 600 so as to surround the opening 603. The frame portion 601 may be disposed to surround the seating portion 602.

[0067] The frame portion 601 may include a connection portion 6012 configured to space the placement portion 602 from the substrate 400 and extend from the placement portion 602, and a support portion 6011 located between the connection portion 6012 and the substrate 400 and supported by the substrate 400. The connection portion 6012 may be in a shape extending from the placement portion 602 in a direction perpendicular to the optical axis direction. The support portion 6011 may extend from one region of the connection portion 6012 in the optical axis direction. In addition, the frame portion 601 may include a guide portion 6013 surrounding the placement portion 602 and protruding in the optical axis direction. The guide portion 6013 may guide the position on which the infrared filter 700 is placed.

[0068] Due to the opening 603 of the sub-housing 600, a space portion may be formed on the inner side of the sub-housing 600. The infrared filter 700 may be disposed above the space portion, and the image sensor 500 may be located below the space portion. The sub-housing 600 may have a gas exhaust portion 800 that penetrates the sub-housing 600. Therefore, the gas generated when the infrared filter 700 and the sub-housing 600 are joined may be exhausted from the inner space of the sub-housing 600 to the outside of the sub-housing 600.

[0069] The sub-housing 600 may have an inner surface facing the image sensor 500 and an outer surface facing the outside. Specifically, the inner surface of the sub-housing 600 may define an inner space portion accommodating the image sensor 500, and the outer surface may refer to a surface facing the outside of the sub-housing 600, excluding the inner surface.

[0070] The gas exhaust portion 800 may be located below the seating portion 602. The frame portion 601 may have the gas exhaust portion 800. The gas exhaust portion 800 may include a first channel 801 penetrating the sub-housing 600 from the inner surface of the sub-housing 600 to the outer surface of the sub-housing 600 and a second channel 802 extending from the first channel 801 to the outer surface of the sub-housing 600 along the optical axis direction.

[0071] The first channel 801 may extend from the inner surface of the frame portion 601 to the outside of the sub-housing 600. The first channel 801 may extend in a direction perpendicular to the optical axis direction. The first channel 801 may extend in a straight line. The first channel 801 may have a quadrilateral (e.g., rectangular) cross-sectional shape, but is not limited thereto, and may have any shape that allows gas to pass through the first channel 801. Reference Figure 5 , the first channel 801 can penetrate the connecting portion 6012 from the inner surface of the connecting portion 6012 to the outer surface of the connecting portion 6012.

[0072] The second channel 802 may extend from a region of the first channel 801 in the optical axis direction. The second channel 802 may extend in a straight line. The second channel 802 may have a quadrilateral (e.g., rectangular) cross-sectional shape, but is not limited thereto, and may have any shape that allows gas to pass through the second channel 802.

[0073] The sub-housing 600 may have a first opening 604 penetrated by the first passage 801 and located on the inner surface, and a second opening 605 penetrated by the first passage 801 and located on the outer surface. In other words, the first opening 604 and the second opening 605 may be located at both ends of the first passage 801, respectively. The first passage 801 may be communicated with the inner space of the sub-housing 600 through the first opening 604, and may be communicated with the outside of the sub-housing 600 through the second opening 605. When the first passage 801 extends in a straight line in a direction perpendicular to the optical axis direction, the central axes of the second opening 605 and the first opening 604 may have the same height.

[0074] The sub-housing 600 may have a third opening 606 that is penetrated from the first channel 801 by the second channel 802 in the optical axis direction and is located on the outer surface. The first end of the second channel 802 can be communicated with the outside of the sub-housing 600 through the third opening 606, and the second end can be connected to the first channel 801. When the first channel 801 extends in a straight line in a direction perpendicular to the optical axis direction, the third opening 606 and the second opening 605 can be positioned in a direction perpendicular to the optical axis direction. In other words, the second opening 605 is located on the side surface of the sub-housing 600 facing the direction perpendicular to the optical axis direction, and the third opening 606 is located on the upper surface of the sub-housing 600 in the optical axis direction.

[0075] refer to Figure 6 , the filler material 900 may be configured to fill at least a portion of the second channel 802. The filler material 900 may be configured to fill the region where the first channel 801 and the second channel 802 overlap each other along the optical axis direction. The filler material 900 may include an adhesive material. The filler material 900 may include an epoxy resin. The filler material 900 may be configured to fill at least a portion of the second channel 802 and a portion of the first channel 801 after the gas caused by the curing of the adhesive material is fully discharged to the outside. As described above, by using the filler material 900 to seal the portion through which the gas discharge portion 800 communicates with the outside, process defects caused by the entry of external flowable foreign matter through the portion opened for gas discharge can be prevented.

[0076] Since the gas exhaust portion 800 is located below the seating portion 602, the seating portion 602 may not need to be provided with an independent structure for exhausting gas. An adhesive may be provided between the seating portion 602 and the infrared filter 700, and the adhesive may be provided to cover the region where the seating portion 602 and the infrared filter 700 overlap each other. As described above, since the adhesive is applied to the entire region of the upper surface of the seating portion 602 that overlaps the infrared filter 700, a flare phenomenon may be prevented compared to a case where a groove for gas exhaust is provided on the upper surface of the seating portion 602 so that there is a region where no adhesive is applied.

[0077] In the following, reference Figure 7 , a sub housing 600 of the camera module 10 according to a modified embodiment will be described. Figure 7 It is shown along Figure 2 2 is a cross-sectional view of a portion of a camera module according to a modified embodiment taken along line VV′.

[0078] Unlike the camera module according to the embodiment described above, in the camera module according to the modified embodiment, the gas exhaust portion 800 may be located in the lower portion of the sub-housing 600 along the optical axis direction. In other words, the first channel 801 may penetrate the support portion 6011 from the inner surface of the support portion 6011 to the outer surface of the support portion 6011.

[0079] In the following, reference Figure 8 , a sub housing 600 of the camera module 10 according to another modified embodiment will be described. Figure 8 It is shown along Figure 2 2 is a cross-sectional view of a portion of a camera module according to another modified embodiment taken along line VV′.

[0080] Unlike the camera module according to the embodiment described above, in the camera module according to the modified embodiment, the first opening 604 may be located on the lower surface along the optical axis direction of the sub housing 600 .

[0081] In other words, refer to Figure 7 and Figure 8 As long as the gas exhaust portion 800 can connect the inner space portion of the sub-housing 600 to the outside by penetrating the sub-housing 600 from the inner surface to the outer surface, the position of the first channel 801 may be configured in any other scheme.

[0082] In the following, reference Fig. 9 and Fig.10 , the sub housing 600 of the camera module 10 according to another embodiment will be described in further detail.

[0084] Unlike the above-described camera module according to the embodiment, in the camera module according to the modified embodiment, the first channel 801 may have a plurality of curved portions. The first channel 801 may penetrate the connecting portion 6012 from the inner surface of the connecting portion 6012 to the outer surface of the connecting portion 6012. The first channel 801 may have a quadrilateral (e.g., rectangular) cross-sectional shape, but is not limited thereto, and may have any shape that allows gas to pass through the first channel 801.

[0085] In addition, when the first channel 801 extends in a direction perpendicular to the optical axis direction to have a plurality of curved portions, the third opening 606 and the second opening 605 can be disposed offset relative to the direction perpendicular to the optical axis direction. As described above, by forming the gas discharge portion 800 in a curved shape rather than a straight line, it is possible to effectively block entry of foreign matter from the outside while easily discharging the gas caused by the curing of the adhesive material to the outside.

[0086] In the following, reference Fig.11 , a modification of a camera module according to another embodiment will be described. Fig.11 It is shown along Figure 2 2 is a cross-sectional view of a portion of a camera module according to a modified embodiment of another embodiment, taken along line VV′ of FIG.

In other words, the first channel 801 may penetrate the support portion 6011 from the inner surface of the support portion 6011 to the outer surface of the support portion 6011. The first opening 604 may be disposed lower than the second opening 605 in the optical axis direction.

[0088] Reference together Fig.10 and Fig.11 As long as the gas exhaust portion 800 can connect the inner space portion of the sub-housing 600 to the outside by penetrating the sub-housing 600 from the inner surface to the outer surface, the position of the first channel 801 may be configured in any other scheme.

[0089] At least one of the embodiments attempts to provide a camera module that can easily discharge gas caused by curing adhesive to the outside and effectively block entry of foreign matter from the outside.
