As shown in fig. 1 and fig. 2, an embodiment of the first aspect of the present invention provides a lens holder 100, where the lens holder 100 includes a holder body 10 and a concave-convex pattern 20. Wherein, a bonding region for applying glue is provided at the top of the seat body 10, and the concave-convex lines 20 are formed in the bonding region.
According to the embodiment of the present invention, the lens mount 100 is provided with a bonding area at the top of the mount body 10, wherein the bonding area is used for coating glue, so as to be connected with the lens in a gluing manner. Concave-convex lines 20 are formed in the bonding region, and the arrangement of the concave-convex lines 20 can improve the infiltration degree of glue on the surface of the lens seat 100, so that the contact point density between the glue and the lens seat 100 is increased, the bonding strength between the lens seat 100 and a lens is further improved, and the bonding firmness between the glue and the lens is improved.
In some embodiments of the present invention, as shown in fig. 3, the concave-convex pattern 20 includes a plurality of spaced and parallel linear shallow grooves 201, the linear shallow grooves 201 form a concave portion in the concave-convex pattern 20, and the structure between the two linear shallow grooves 201 forms a convex portion in the concave-convex pattern 20. The straight shallow groove 201 is easy to process, and can effectively increase the contact point density between the glue and the lens holder 100, thereby improving the bonding strength between the lens holder 100 and the lens.
Further, the distance between two adjacent straight-type shallow grooves 201 is 0.1 to 0.5 mm. If the interval between the linear shallow grooves 201 is too large, the number of the linear shallow grooves 201 formed in the bonding region is small, that is, the grain distribution is thin, in which case the contact point density between the glue and the lens holder 100 cannot be increased significantly, resulting in an insignificant effect of improving the bonding strength between the lens holder 100 and the lens. Conversely, if the pitch between the straight-type shallow grooves 201 is too small, the effective contact area between the lens holder 100 and the lens is significantly reduced, and the connection strength between the lens holder 100 and the lens is weakened. Through a large number of numerical simulations and experimental verifications, the distance between every two adjacent linear shallow grooves 201 is set within the range of 0.1 to 0.5mm, so that the problems in the two aspects can be effectively overcome, and the effect of obviously improving the bonding strength between the lens mount 100 and the lens is further achieved.
In some embodiments of the present invention, as shown in fig. 4, the concave-convex patterns 20 include a plurality of first linear shallow grooves 202 arranged in parallel at intervals and a plurality of second linear shallow grooves 203 arranged in parallel at intervals, and the first linear shallow grooves 202 and the second linear shallow grooves 203 are arranged in a crossing manner to form a grid-shaped shallow grooves. In the present embodiment, the concave-convex pattern 20 is a grid-shaped shallow groove formed by intersecting the plurality of first straight-line shallow grooves 202 and the plurality of second straight-line shallow grooves 203, so that the contact point density between the glue and the lens holder 100 can be greatly increased, and the bonding strength between the lens holder 100 and the lens can be greatly improved.
Further, the pitch between two adjacent first straight-line shallow grooves 202 is 0.1 to 0.5mm, and the pitch between two adjacent second straight-line shallow grooves 203 is 0.1 to 0.5 mm. Since the grid-shaped shallow grooves are formed by two sets of straight-line shallow grooves 201, namely the first straight-line shallow groove 202 and the second straight-line shallow groove 203, the preferable range of the distance between two adjacent straight-line shallow grooves 201 is 0.1 to 0.5mm for each set of straight-line shallow grooves 201 (for the reason that please refer to the foregoing). Therefore, in the case where the pitch between the adjacent two first straight-line type shallow grooves 202 is 0.1 to 0.5mm and the pitch between the adjacent two second straight-line type shallow grooves 201 is 0.1 to 0.5mm, the adhesive strength between the lens holder 100 and the lens can be greatly improved.
In some embodiments of the utility model, concave-convex lines 20 include a plurality of interval arrangement's broken line type shallow slot (not shown), compare in linear type shallow slot 201, and the broken line type shallow slot can further increase the shared area of concave-convex lines 20 to increase the contact point density between glue and the lens mount 100, and then improve the bonding strength between lens mount 100 and the camera lens.
Further, the distance between two adjacent broken line type shallow grooves is 0.1 to 0.5mm, so that on one hand, the contact point density between the glue and the lens mount 100 can be obviously increased, and the effective contact area between the lens mount 100 and the lens can not be obviously reduced, therefore, the effect of obviously improving the bonding strength between the lens mount 100 and the lens can be obtained.
In some embodiments of the present invention, the width of the concave-convex lines 20 is 0.1 to 0.5mm, and the depth of the concave-convex lines is 0.1 to 0.5 mm. It should be noted that the width and depth of the concave-convex vein 20 herein refer to the width and depth of each vein (i.e. shallow groove) included in the concave-convex vein 20. For example, for an embodiment in which the uneven pattern 20 includes a plurality of spaced and parallel straight shallow grooves 201, the width of each straight shallow groove 201 is 0.1 to 0.5mm, and the depth of each straight shallow groove 201 is 0.1 to 0.5 mm. For another example, for an embodiment in which the concave-convex vein 20 includes a plurality of first straight-line shallow grooves 202 and a plurality of second straight-line shallow grooves 203, and the first straight-line shallow grooves 202 intersect with the second straight-line shallow grooves 203 to form a grid-shaped shallow groove, the width and depth of each first straight-line shallow groove 202 are 0.1 to 0.5mm, and the width and depth of each second straight-line shallow groove 203 are 0.1 to 0.5 mm. Through a large number of numerical simulations and experiments, the adhesive strength between the lens holder 100 and the lens is strongest under the condition that the width of the concave-convex lines 20 is 0.1 to 0.5mm and the depth is 0.1 to 0.5 mm.

In this embodiment, the adhesive region is disposed on the protrusion 30, which is beneficial to ensure sufficient contact between the adhesive region and the lens, thereby promoting a more firm adhesion between the lens holder 100 and the lens.
In some embodiments of the present invention, the seat body 10 is formed with a containing cavity 11 for containing the image sensor, the top of the seat body 10 is formed with a light hole, the protruding portion 20 is an annular structure, and the inner cavity of the annular structure is communicated with the containing cavity 11 through the light hole. When assembling the lens mount 100 with the lens, the image sensor is first disposed in the accommodating cavity 11 of the mount body 10 and disposed corresponding to the light-transmitting hole, and then the lens is bonded to the top surface of the protrusion 20, so that light passing through the lens can be imaged on the image sensor. The accommodating cavity 11 is configured to provide a stable working environment for the image sensor, so that the image sensor can effectively receive light signals to form an image.
An embodiment of the second aspect of the present invention provides an image capturing apparatus, which includes a lens and a lens mount 100, wherein the lens mount 100 is the lens mount in any of the above embodiments. The lens is attached to the adhesive area of the lens holder 100 by gluing.
