Abstract
Description
Technical Field
[0001] The present invention relates to the field of camera technology, and in particular to a lens and electronic equipment. Background Art
[0002] In recent years, as the requirements for lens reliability have become higher and higher, lens reliability has become an important indicator for evaluating the quality of lenses. However, the adhesives currently used in lenses are not only costly, time-consuming and inefficient to manufacture, but the reliability of lenses made with current adhesives is also poor. Summary of the invention
[0003] The object of the present invention is to provide a lens and an electronic device to solve the technical problem of poor reliability of the lens.
[0004] The present invention provides a lens, comprising a lens and a lens barrel, wherein the lens comprises an optical imaging portion and a non-imaging portion surrounding the optical imaging portion, wherein the non-imaging portion comprises an edge portion, wherein the lens is fixed in the lens barrel, and the connection between the edge portion and the lens barrel is formed by mixing and solidifying the partial structure of the edge portion and the partial structure of the lens barrel after the partial structure of the edge portion is dissolved by a solvent. The present application realizes stable bonding of the edge portion and the lens barrel through the dissolution process, mixing process and solidification process of the partial structure of the edge portion and the partial structure of the lens barrel in the solvent, so that the lens and the lens barrel can be bonded together more stably, with good reliability, and avoids the technical problem of damage to the lens caused by the separation of the lens barrel and the lens when the lens shakes. Moreover, after the lens and the lens barrel are bonded by the solvent of the present application, the lens and the lens barrel can be fused together, with good reliability.
[0005] Wherein, the partial structure of the edge portion and the partial structure of the lens barrel are both physically dissolved in the solvent; or, the partial structure of the edge portion and the partial structure of the lens barrel are both chemically dissolved in the solvent; or, one of the partial structure of the edge portion and the partial structure of the lens barrel is chemically dissolved in the solvent, and the other is physically dissolved in the solvent. The solvent dissolves the partial structure of the edge portion by either physical dissolution or chemical dissolution, and the solvent dissolves the partial structure of the edge portion and the partial structure of the lens barrel by either physical dissolution or chemical dissolution. The solvent dissolves the partial structure of the edge portion and the partial structure of the lens barrel in a flexible manner, which improves the versatility of the solvent and increases the range of solvent selection.
[0006] Wherein, the non-imaging portion also includes a transition portion, the transition portion is arranged between the optical imaging portion and the edge portion, the transition portion is a closed ring formed around the optical imaging portion, the edge portion is a closed ring formed around the transition portion, and the transition portion is made of the same material as the optical imaging portion. The optical imaging portion of the present application is used for imaging to ensure optical performance. The transition portion is made of the same material as the optical imaging portion, so that the transition portion and the optical imaging portion can be molded together to ensure eccentricity.
[0007] The edge portion includes at least two connecting portions, the centers of the at least two connecting portions are arranged at equal angles around the optical axis of the lens, and the portion of the edge portion dissolved by the solvent is the connecting portion. In this way, the at least two connecting portions can increase the bonding area between the edge portion and the lens barrel, and the equal angle arrangement of the centers of the at least two connecting portions can make the bonding position between the edge portion and the lens barrel more uniform, and the bonding between the lens and the lens barrel is more uniform and more stable.
[0008] The partial structure of the edge portion dissolved by the solvent is located at the entire periphery of the edge portion. Thus, the solvent will dissolve and bond the partial structure of the edge portion and the partial structure of the lens barrel over the entire periphery, with a large dissolved area and a good bonding effect. That is, the solvent will bond and fix the partial structure of the edge portion and the partial structure of the lens barrel within a range of 360°, and the solvent bonding range is larger, so that the lens and the lens barrel can be fixed more firmly.
[0009] Wherein, each of the connecting parts is provided with a notch connecting the image side surface and the side surface of the non-imaging part, and the connection between the lens and the lens barrel is formed by the solvent entering from the notch and dissolving the partial structure of the lens barrel and the partial structure of the connecting part adjacent to the notch, and then mixing and solidifying. Thus, the provision of the notch can make the effect of bonding the solidified edge part with the solidified lens barrel better. This will greatly improve the reliability of the lens, and the lens is reliable.
[0010] The edge portion is formed with an annular notch connecting the image side surface and the side surface of the non-imaging portion, and the connection between the lens and the lens barrel is formed by the solvent entering from the notch and dissolving the partial structure of the lens barrel and the partial structure of the edge portion adjacent to the notch, and then mixing and solidifying. Thus, the annular notch is used to accommodate the solvent, and the setting of the annular notch can allow more solvent to enter between the lens barrel and the lens, and more solvent will dissolve a larger volume of the lens barrel and a larger volume of the lens, so the amount of the dissolved edge portion and the dissolved lens barrel mixed in the solvent is more, and the mixing effect is better, and then the bonding effect of the solidified edge portion and the solidified lens barrel is better. This will greatly improve the reliability of the lens, and the lens is reliable.
[0011] Wherein, in the direction parallel to the optical axis, the ratio X of the depth of the notch to the maximum thickness of the non-imaging portion is in the range of 3 / 10≤X≤9 / 10, and the ratio Y of the width of the notch in the radial direction of the lens to the width of the non-imaging area in the radial direction of the lens is in the range of 3 / 10≤Y≤9 / 10. The depth and width of the notch are such that the amount of solvent is not too small, so that the effect of solvent dissolving and bonding the lens is not rational, and the amount of solvent is not too large, so that too much solvent affects the performance of the lens and the lens barrel.
[0012] Wherein, the lens is the lens closest to the image side end of the lens barrel in a lens group. Therefore, when the lens closest to the image side end is dissolved and bonded to the lens barrel, all the lenses in the lens group can be fixed in the lens barrel more firmly.
[0013] The outer surface of the edge portion is a curved surface, and the inner surface of the edge portion is a plane, a curved surface or a folded surface; and / or the cross-sectional shape of the edge portion is an ellipse, a crescent, an arch, a fan, a serrated, a crown or a square. The outer surface of the edge portion is a curved surface so that the edge portion can be better installed in the lens barrel.
[0014] The present invention provides an electronic device, which includes the above-mentioned lens. The electronic device of the present application achieves stable bonding between the edge portion and the lens barrel through the dissolution process, mixing process and curing process of the partial structure of the edge portion and the partial structure of the lens barrel in the solvent, so that the lens and the lens barrel can be bonded together more stably, with good reliability, and avoids the technical problem of damage to the lens caused by the separation of the lens barrel and the lens when the lens shakes. Moreover, after the lens and the lens barrel are bonded using the solvent of the present application, the lens and the lens barrel can be fused together, with good reliability.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0026] The present invention provides an electronic device, wherein the electronic device comprises a lens. The lens will be described in detail as follows.
[0027] See also Figure 1 The lens includes a lens 10 and a lens barrel 20. The lens 10 includes an optical imaging portion 101a and a non-imaging portion 40 surrounding the optical imaging portion 101a. The non-imaging portion 40 includes an edge portion 102. The lens 10 is fixed in the lens barrel 20. The connection between the edge portion 102 and the lens barrel 20 is formed by mixing and solidifying a partial structure of the edge portion 102 and a partial structure of the lens barrel 20 after the solvent 30 dissolves the mixture.
[0028] The lens may include one lens, or a lens group consisting of a plurality of lenses. When it is a lens group, the lens 10 is the lens closest to the image side end of the lens barrel 20. Therefore, when the lens closest to the image side end is dissolved and bonded to the lens barrel 20, the lenses in the lens group can be fixed relatively firmly in the lens barrel 20. In this embodiment, for ease of description, only one lens, namely the lens 10, is shown, and actual applications are not limited to this embodiment.
[0029] It is understandable that the solvent dissolves the materials of the two pre-bonded structures and mixes them with each other. After the dissolved materials are solidified, the pre-bonded structures are bonded to each other. In the present application, under the action of the solvent 30, the partial structure of the edge portion 102 and the partial structure of the lens barrel 20 are dissolved in the solvent 30, the dissolved edge portion 102 is mixed with the dissolved lens barrel 20, and after the dissolved edge portion 102 and the dissolved lens barrel 20 are solidified, the edge portion 102 and the lens barrel 20 are bonded. The solvent 30 can be an organic solvent.
[0030] Thus, the present application realizes the stable bonding of the edge portion 102 and the lens barrel 20 through the dissolution process, mixing process and curing process of the partial structure of the edge portion 102 and the partial structure of the lens barrel 20 in the solvent 30, so that the lens 10 and the lens barrel 20 can be bonded together more stably, with good reliability, and avoids the technical problem of damage to the lens caused by the separation of the lens barrel 20 and the lens 10 when the lens shakes. Moreover, after the lens 10 and the lens barrel 20 are bonded using the solvent 30 of the present application, the lens 10 and the lens barrel 20 can be fused together, with good reliability.
[0031] The thrust of the solvent 30 used in the present application is at least twice that of the glue, and the bonding performance of the solvent 30 is better than that of the glue. In other words, the solvent 30 not only has the bonding performance of the glue, but also has a better bonding effect than the glue, which can improve the production efficiency. Therefore, the use of the solvent 30 in the present application also avoids the technical problems of poor bonding performance, high process cost and low efficiency caused by the use of glue.
[0032] The edge portion 102 includes a first body and a first fixing portion connected to the first body, the first fixing portion faces the lens barrel 20, the lens barrel 20 includes a second body and a second fixing portion connected to the second body, the second fixing portion faces the edge portion 102, and the first fixing portion and the second fixing portion are fixedly connected after being dissolved by the solvent 30. Thus, the present application can achieve the fixed connection between the edge portion 102 and the lens barrel 20 only by dissolving and bonding the first fixing portion and the second fixing portion, and achieve the fixed connection between the lens 10 and the lens barrel 20. In the case where the dissolution area of the edge portion 102 and the lens barrel 20 is small, the fixed connection between the lens 10 and the lens barrel 20 is achieved. It can be understood that the volume of the first fixing portion is smaller than the volume of the first body, and the volume of the second fixing portion is smaller than the volume of the second body. It can be understood that the first fixing portion is a partial structure of the above-mentioned edge portion 102, and the second fixing portion is a partial structure of the above-mentioned lens barrel 20.
[0033] In a specific embodiment, the edge portion 102 is made of the same material as the lens barrel 20. In this way, the edge portion 102 has the same solubility and curing properties as the lens barrel 20 in the solvent 30, and the dissolved edge portion 102 can be mixed with the dissolved lens barrel 20 better. After the dissolved edge portion 102 and the dissolved lens barrel 20 are cured, the edge portion 102 can be bonded to the lens barrel 20 more firmly, and the lens 10 and the lens barrel 20 can be bonded more firmly. Moreover, the edge portion 102 of the present application is made of the same material as the lens barrel 20, and when the lens 10 and the lens barrel 20 are bonded and fixed with the solvent 30, it is necessary to fix the lens 10 and the lens barrel 20 with the help of a pressure ring of the same material as the lens barrel 20, and the pressure ring not only needs to increase the cost, increase the process, but also the technical problem of taking up space. In other words, the present application saves the use of the pressure ring, saves the cost, saves the process of the pressure ring, and does not need to set the corresponding space in the lens barrel 20 for setting the pressure ring.
[0034] Of course, in other implementations, the materials of the edge portion 102 and the lens barrel 20 can be different, as long as the edge portion 102 and the lens barrel 20 can both be dissolved in the solvent 30. In this way, the dissolved edge portion 102 and the dissolved lens barrel 20 can be mixed, and then after the dissolved edge portion 102 and the dissolved lens barrel 20 are solidified, the edge portion 102 and the lens barrel 20 can also be bonded together.
[0035] In the present application, the solvent 30 can not only dissolve the same material, but also dissolve different materials, as long as the two dissolved materials can be mixed and the two materials can be bonded together after solidification.
[0036] In a specific embodiment, the non-imaging portion 40 further includes a transition portion 101b, which is disposed between the optical imaging portion 101a and the edge portion 102. The transition portion 101b is a closed ring formed around the optical imaging portion 101a, and the edge portion 102 is a closed ring formed around the transition portion 101b. The transition portion 101b is made of the same material as the optical imaging portion 101a. The optical imaging portion 101a is used for imaging to ensure optical performance. The transition portion 101b is made of the same material as the optical imaging portion 101a, so that the transition portion 101b can be formed together with the optical imaging portion 101a to ensure eccentricity.
[0037] In a specific embodiment, the solubility of the edge portion 102 in the solvent 30 is greater than the solubility of the transition portion 101b in the solvent 30. The solubility of the edge portion 102 in the solvent 30 is greater than the solubility of the optical imaging portion 101a in the solvent 30. Specifically, when the solubility of the edge portion 102 in the solvent 30 is not only greater than that of the optical imaging portion 101a, but also greater than that of the transition portion 101b, the amount of the edge portion 102 dissolved in the solvent 30 is greater, and the amount of the dissolved edge portion 102 and the dissolved lens barrel 20 mixed in the solvent 30 is greater, the mixing effect is better, and then the effect of the solidified edge portion 102 and the solidified lens barrel 20 bonding is better. This will greatly improve the reliability of the lens, and the lens is reliable.
[0038] It can be understood that the dissolution process of the partial structure of the edge portion 102 and the partial structure of the lens barrel 20 in the solvent 30 of the present application can be that the partial structure of the edge portion 102 and the partial structure of the lens barrel 20 are physically dissolved in the solvent 30, and the materials of the edge portion 102 and the lens barrel 20 do not change. The dissolved material of the edge portion 102 and the dissolved material of the lens barrel 20 are mixed and solidified, so that the edge portion 102 and the lens barrel 20 are bonded, and the material of the edge portion 102 after solidification and the material of the lens barrel 20 after solidification do not change. Of course, the dissolution process of the partial structure of the edge portion 102 and the partial structure of the lens barrel 20 in the solvent 30 can also be that the partial structure of the edge portion 102 and the partial structure of the lens barrel 20 are chemically dissolved in the solvent 30, and the material of the edge portion 102 and the material of the lens barrel 20 are changed, and other materials are generated. After the newly generated material is solidified, the edge portion 102 and the lens barrel 20 are bonded, and the edge portion 102 and the lens barrel 20 can also be bonded. Of course, the dissolution process of the partial structure of the edge portion 102 and the partial structure of the lens barrel 20 in the solvent 30 can also be that one of them is chemically dissolved in the solvent 30 and the other is physically dissolved in the solvent 30; the dissolved edge portion 102 and the dissolved lens barrel 20 are fixedly connected after solidification.
[0039] In a specific embodiment, there is a gap between the edge portion 102 and the lens barrel 20, and the distance of the gap is within the range of 0.005mm to 0.03mm. Specifically, the edge portion 102 will have a certain eccentricity relative to the center of the optical imaging portion 101a, and the gap between the edge portion 102 and the inner wall of the lens barrel 20 can ensure that the assembly eccentricity of the lens 10 and the lens barrel 20 meets the requirements. Moreover, the gap is also more conducive to better penetration of the solvent 30 to bond the edge portion 102 and the lens barrel 20. The gap within the range of 0.005mm to 0.03mm is neither too large to cause the lens 10 to loosen relative to the lens barrel 20 and waste the solvent 30, and the gap within the range of 0.005mm to 0.03mm is not too small to meet the requirements of assembly eccentricity.
[0040] See also Figure 2 In a specific embodiment, the edge portion 102 includes at least two connecting portions 80, and the centers of the at least two connecting portions 80 are arranged at equal angles around the optical axis of the lens. The part of the structure of the edge portion 102 dissolved by the solvent 30 is the connecting portion 80. Specifically, the centers of two adjacent connecting portions 80 form an angle with the line connecting the center of the lens 10. In the circumferential direction of the lens 10, the angles formed by the centers of every two adjacent connecting portions 80 and the line connecting the center of the lens 10 are equal. In this way, the at least two connecting portions 80 can increase the bonding area between the edge portion 102 and the lens barrel 20, and the equal angle arrangement of the centers of the at least two connecting portions 80 can make the bonding position of the edge portion 102 and the lens barrel 20 more uniform, and the bonding between the lens 10 and the lens barrel 20 is more uniform and more stable.
[0041] Please continue reading Figure 2 It can be understood that there are two connecting parts 80, and the two connecting parts 80 are symmetrically arranged on opposite sides of the lens 10. The symmetrical arrangement of the two connecting parts 80 can make the bonding area between the lens barrel 20 and the edge part 102 larger, and the lens 10 and the lens barrel 20 are bonded and fixed more firmly.
[0042] It is understandable that there may be three or more connecting parts 80. The centers of the three or more connecting parts 80 are arranged at equal angles around the optical axis of the lens.
[0043] Please continue reading Figure 2 In a specific embodiment, each connecting portion 80 is provided with a notch 90 connecting the image side surface and the side surface of the non-imaging portion 40. The connection between the lens 10 and the lens barrel 20 is formed by the solvent 30 entering from the notch 90 and dissolving the partial structure of the lens barrel 20 and the partial structure of the connecting portion 80 adjacent to the notch, and then mixing and solidifying. It can be understood that the notch 90 is used to accommodate the solvent 30. The setting of the notch 90 can allow more solvent 30 to enter between the lens barrel 20 and the lens 10. More solvent 30 will dissolve a larger volume of the lens barrel 20 and a larger volume of the lens 10, and the amount of the dissolved edge portion 102 and the dissolved lens barrel 20 mixed in the solvent 30 will be greater, and the mixing effect will be better, and then the solidified edge portion 102 will have a better bonding effect with the solidified lens barrel 20. This will greatly improve the reliability of the lens, and the lens is reliable.
[0044] Therefore, the provision of the notch 90 can make the effect of bonding the cured edge portion 102 to the cured lens barrel 20 better, which will greatly improve the reliability of the lens and make the lens reliable.
[0045] See also Figure 3In a specific embodiment, the partial structure of the edge portion 102 dissolved by the solvent 30 is located on the entire periphery of the edge portion 102 . It can be understood that the connecting portion 80 is a connecting ring located on the entire periphery of the edge portion 102 .
[0046] Thus, the solvent 30 will dissolve and bond the entire periphery of the edge portion 102 and the lens barrel 20, the dissolved area is large, and the bonding effect is good. That is, the solvent 30 will bond and fix the partial structure of the edge portion 102 and the partial structure of the lens barrel 20 within a range of 360°, the scope of the solvent 30 bonding is larger, and the lens 10 and the lens barrel 20 can be fixed more firmly. This embodiment is applicable to the case where the eccentricity of the lens 10 is insensitive, or the eccentricity of the mold can be done better. The solvent 30 bonds the partial structure of the edge portion 102 for one circle and the partial structure of the lens barrel 20 for one circle, the connection range is larger, the bonding effect is better, and the lens 10 and the lens barrel 20 can be fixed more firmly.
[0047] Please continue reading Figure 3 In a specific embodiment, the edge portion 102 is formed with an annular notch 90 that connects the image side surface and the side surface of the non-imaging portion, and the connection between the lens 10 and the lens barrel 20 is formed by a solvent entering from the notch 90 and dissolving a part of the lens barrel 20 structure and a part of the edge portion 102 structure adjacent to the notch 90, and then mixing and solidifying. It can be understood that the annular notch 90 in this embodiment is located at the entire periphery of the edge portion 102.
[0048] It is understandable that the annular notch 90 is used to accommodate the solvent 30. The setting of the annular notch 90 allows more solvent 30 to enter between the lens barrel 20 and the lens 10. More solvent 30 will dissolve a larger volume of the lens barrel 20 and a larger volume of the lens 10, so that the dissolved edge portion 102 and the dissolved lens barrel 20 are mixed in the solvent 30 in a larger amount, and the mixing effect is better, and then the solidified edge portion 102 and the solidified lens barrel 20 are bonded to a better effect. This will greatly improve the reliability of the lens, and the lens is reliable.
[0049] Therefore, the provision of the annular notch 90 can make the solidified edge portion 102 and the solidified lens barrel 20 bonded better, which will greatly improve the reliability of the lens.
[0050] In a specific embodiment, in the direction parallel to the optical axis, the ratio X of the depth of the notch 90 to the maximum thickness of the non-imaging portion 40 is in the range of 3 / 10≤X≤9 / 10, and the ratio Y of the width of the notch 90 in the radial direction of the lens 10 to the width of the non-imaging area 40 in the radial direction of the lens 10 is in the range of 3 / 10≤Y≤9 / 10.
[0051] It can be understood that the length of the notch 90 in the optical axis direction is the depth, and the length of the notch 90 in the radial direction is the width.
[0052] The above-mentioned depth and width of the notch 90 can not only accommodate more solvent 30 to meet the bonding requirements of the lens 10 and the lens barrel 20, but also prevent the notch 90 from accommodating too much solvent 30 so that the solvent 30 dissolves too much lens 10 and the lens barrel 20 to affect the performance of the lens 10 and the lens barrel 20. In other words, the notch 90 of the above-mentioned depth and width will not make the amount of solvent 30 too small, so that the effect of solvent 30 dissolving and bonding the lens 10 is not rational, nor will it make the amount of solvent 30 too large, so that too much solvent 30 affects the performance of the lens 10 and the lens barrel 20. In a specific embodiment, the thickness of the edge portion 102 is greater than 0.1 mm. The edge portion 102 with a thickness greater than 0.1 mm can fully meet the bonding requirements of the edge portion 102 and the lens barrel 20.
[0053] In a specific embodiment, the outer surface of the edge portion 102 is a curved surface, and the inner surface of the edge portion is a plane, a curved surface or a folded surface. The outer surface of the edge portion 102 is a curved surface so that the edge portion 102 can be installed in the lens barrel 20 better.
[0054] Specifically, if the inner surface of the edge portion 102 is arc-shaped and the outer surface of the edge portion 102 is arc-shaped, the cross-sectional shape of the edge portion 102 is an ellipse ( Figure 4 ) or crescent-shaped ( Figure 5 If the inner surface of the edge portion 102 is a plane and the outer surface of the edge portion 102 is an arcuate surface, the cross-sectional shape of the edge portion 102 is an arcuate shape ( Figure 6 If the inner surface of the edge portion 102 is a folded surface, the folded surface includes two surfaces, and the two surfaces are arranged at an angle, then the cross-sectional shape of the edge portion 102 is a fan-shaped ( Figure 7 ); Of course, the folding surface may also include more surfaces, and the two surfaces connected by one surface extend in different directions, and the inner surface of the edge portion 102 forms a serrated shape.
[0055] If the inner surface of the edge portion 102 is a folded surface, the folded surface includes three surfaces, two adjacent surfaces are arranged at an angle, and two surfaces connected by one surface extend in the same direction, then the cross-sectional shape of the edge portion 102 can be a crown shape ( Figure 8 ), or a square-shaped ( Fig. 9 ), or other shapes. Of course, the folding surface can include more surfaces, and two surfaces connected by one surface extend in the same direction, and the edge portion 102 can form more shapes.
[0056] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, all possible combinations of the technical features in the above embodiments are not described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0057] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
