Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, a lens module 100a in the related art includes a lens barrel 110a, a lens group 120a and a pressing ring 130a, wherein the lens barrel 110a has an inner cavity 111a and an inner peripheral wall 112a facing the inner cavity 111 a. The lens group 120a is mounted in the inner cavity 111a of the lens barrel 110a, and the lens group 120a abuts against the inner peripheral wall 112a of the lens barrel 110a, wherein the lens group 120a includes at least one lens, and a lens of the lens group 120a closest to the image side end of the lens barrel 110a abuts against the press ring 130 a. The inner peripheral wall 112a and the pressing ring 130a together define a dispensing slot 140a, and the adhesive 150a fills the dispensing slot 140 a. The press ring 130a is configured to provide a pressing force to the lens group 120a when the lens barrel 110a is fixedly connected with the adhesive 150a, so as to fasten the lens group 120a in the inner cavity 111a of the lens barrel 110 a.
However, in the dispensing process, the dispensing groove 140a needs to dispense the adhesive 150a on the inner peripheral wall 112a, and then the adhesive 150a flows into the dispensing groove 140a along the inner peripheral wall 112a due to the fluidity of the adhesive 150a, but the dispensing method may cause a portion of the adhesive 150a to remain on the inner peripheral wall 112a, and the condensed adhesive is prone to have a risk of stray light of the adhesive, so that the resolution of the lens assembly 120a is deteriorated, and the product yield of the lens module 100a and the user experience are affected.
In view of the above technical problem, as shown in fig. 3 to 6, a first embodiment of the present invention provides a lens barrel 100. The lens barrel 100 includes a barrel 110 and a protective film 120. The cylinder 110 includes an inner peripheral wall, the inner peripheral wall includes a first wall surface 111, the first wall surface 111 and the press ring 200 together define the dispensing slot 130, and the protective film layer 120 is disposed on a partial region of the first wall surface 111 close to the image-side end of the cylinder 110. It should be understood that the first wall 111 may be a single wall of the dispensing slot 130, that is, the first wall 111 and the pressing ring 200 together define the dispensing slot 130, and instead of the dispensing slot 130 being defined by only two structures, that is, the first wall 111 and the pressing ring 200 only enclose two structures, and in some embodiments, the first wall 111 may also be represented as a surface formed by splicing a plurality of walls of the dispensing slot 130. When dispensing operation is performed in the dispensing slot 130, the first wall 111 can be used to guide the adhesive 140 to slide into the dispensing slot 130. In other embodiments, the first wall 111 can be adapted to the dispensing slot 130, and the specific shape can be any shape. In this embodiment, when dispensing is performed in the dispensing slot 130, the adhesive 140 slides into the dispensing slot 130 along the protective film layer 120, and the shear viscosity between the protective film layer 120 and the adhesive 140 is smaller than the shear viscosity between the first wall 111 and the adhesive 140.
In this embodiment, the adhesive 140 does not directly contact with the portion of the first wall 111 close to the side end of the cylinder 110 in the dispensing process, and the shear viscosity between the protective film layer 120 and the adhesive 140 is smaller than the shear viscosity between the first wall 111 and the adhesive 140, so that the adhesive 140 can more easily flow into the adhesive dispensing slot 130 and does not adhere to the protective film layer 120. Therefore, in the present embodiment, the region of the first wall surface 111 close to the image side of the lens barrel 110 does not contain the adhesive 140, so that the adhesive 140 is prevented from solidifying on the first wall surface 111 to form a glue body and generating a glue flare risk. The area of the first wall 111 away from the image side of the cylinder 110 is directly bonded to the adhesive 140, so that the pressing ring 200 is fixedly connected to the lens barrel 110 through the adhesive 140. Therefore, in the embodiment, the protective film layer 120 is disposed on the area of the first wall 111 close to the image-side end of the barrel 110, so that the adhesive glue 140 can be prevented from remaining on the area of the first wall 111 close to the image-side end of the barrel 110, thereby eliminating the glue flare phenomenon of the lens barrel 100 and ensuring the resolving power of the lens group 120.
The protective film layer 120 may be attached to the first wall 111. It should be noted that the protective film layer 120 may also be formed on the first wall 111 by knife coating, slit extrusion coating, dispensing, gravure coating, comma roller coating, silk printing, spraying, etc., the present invention only illustrates the protective film layer 120 by attaching, but the present embodiment does not specifically limit the specific forming method of the protective film layer 120.
In order to ensure the reliability of the connection between the pressing ring 200 and the lens barrel 100 and the resolution of the lens group, in the embodiment, the cylinder 110 defines the optical axis 150. The first wall 111 and the protection film layer 120 are both annular, and the annular dispensing slot 130 is defined by the first wall 111 and the pressing ring 200. It should be understood that the protection film layer 120 may have any shape, and may have a regular shape or an irregular shape, for example, the protection film layer 120 having a regular shape may have a rectangular shape, a circular shape, etc., and the specific shape of the protection film layer 120 is not limited in this embodiment. The dispensing slot 130, the first wall 111 and the protection film layer 120 are disposed around the optical axis 150.
In the above embodiment, the annular first wall 111 and the protective film 120 define the annular dispensing slot 130, and it should be noted that the annular first wall and the protective film 120 are only an embodiment of the present invention, and the annular dispensing slot 130 can accommodate more adhesive 140, so as to improve the connection strength between the pressing ring 200 and the lens barrel 100. The annular protective film layer 120 can be circumferentially connected to the first wall surface 111 around the optical axis 150, so that when the dispensing operation is performed on the dispensing slot 130, the adhesive 140 can be completely prevented from directly contacting the first wall surface 111, so that the adhesive 140 can completely flow into the dispensing slot 130, and the risk of glue flare caused by the adhesive 140 remaining on the first wall surface 111 is avoided.
As shown in fig. 7-8, in the second embodiment of the present invention, the barrel 110 may further include a first top surface 112 located at the image-side end, and the first top surface 112 is adjacent to the first wall 111. The protection film layer 120 may include a first connection portion 121 and a second connection portion 122, the first connection portion 121 is connected to the first wall surface 111, and the second connection portion 122 extends from an edge of the first connection portion 121 close to the object side end toward a direction away from the optical axis 150 and is disposed on the first top surface 112. The end of the cylinder 110 facing the object is an object side end, and the end of the cylinder 110 facing away from the object is an image side end.
In this embodiment, the second connection portion 122 of the protection film layer 120 is connected to the first top surface 112, so that the adhesive 140 sputtered on the first top surface 112 can flow into the dispensing slot 130 during the dispensing operation, thereby avoiding the risk of stray light of the adhesive generated when the adhesive 140 remains on the first top surface 112.
The second connecting portion 122 may completely cover the first top surface 112, so that the second connecting portion 122 of the protection film layer 120 completely protects the first top surface 112, but is not limited thereto, and in some embodiments, the first connecting portion 121 may completely cover an inner peripheral wall surface of the lens barrel 110 except the first wall surface 111 to improve product reliability of the lens barrel 100.
As shown in fig. 9 to 10, a third embodiment of the present invention provides a lens module 10 including the lens barrel 100 in the above embodiments. The lens module 10 further includes a pressing ring 200 and a lens assembly 160, wherein the barrel 110 has an inner cavity 113, and the lens assembly 160 is disposed in the inner cavity 113 of the barrel 110. The press ring 200 abuts against the lens group 160 on one side and the inner peripheral wall of the cylinder 110 on the other side. And the peripheral surface of clamping ring 200 is provided with glue storage groove 210, and clamping ring 200 defines some glue grooves 130 with the interior perisporium wall of barrel 110 jointly.
In this embodiment, the protective film layer 120 is disposed on the first wall 111 of the lens module 10 near the image-side end of the barrel 110, so that the adhesive 140 can flow into the adhesive slot 130 more easily when the adhesive slot 130 is dispensing. And the adhesive glue 140 is not left on the area of the first wall surface 111 close to the image side end of the barrel 110, so that the risk of glue flare caused by the adhesive glue 140 solidifying to form a glue on the first wall surface 111 is avoided, and the resolving power of the lens group 160 and the imaging quality of the lens module 10 are ensured.

The pressure ring 200 further includes a first protective film layer 240, the first protective film layer 240 is located in the non-adhesive storage region 220, and the shear viscosity between the first protective film layer 240 and the adhesive is smaller than the shear viscosity between the adhesive storage region 230 and the adhesive.
In this embodiment, the adhesive 140 does not directly contact the non-adhesive storage area 220 of the adhesive storage tank 210, and the shear viscosity between the first protective film layer 240 and the adhesive 140 is smaller than the shear viscosity between the adhesive storage area 230 and the adhesive 140, so that the adhesive 140 can more easily flow into the adhesive storage tank 130. Therefore, the adhesive 140 is not retained in the non-adhesive storage area 220, so that the risk of glue flare caused by the adhesive 140 solidifying on the non-adhesive storage area 220 is avoided, and the resolving power of the lens group 160 is ensured.
