Description

Technical Field

[0001] The utility model belongs to the technical field of lens modules, and specifically relates to a lens module and an electronic product. Background Art

[0002] In the lens production process, in order to ensure that the position of the lens and the screen is more accurate, AA autofocus equipment (Active Alignment technology) is generally used. When the equipment is working, the lens barrel is generally fixed first, and glue is injected into the glue groove on the lens barrel. Then the AA autofocus equipment grabs the screen bracket (with the screen inside) and puts it into the glue groove of the lens barrel. After the camera captures the display center of the screen and the center of the lens, the position of the screen bracket (X / Y / Z direction) is adjusted by the robot arm, and finally the center of the screen and the center of the lens are aligned.

[0003] Since the position of the screen needs to be adjusted, there should be a certain space between the screen bracket and the lens barrel glue groove to avoid interference during the adjustment process. In order to ensure the sealing of the lens barrel, the space between the screen bracket and the lens barrel needs to be sealed. At the same time, in order to ensure that the glue can cure quickly, UV glue needs to be selected. Use UV glue directly to fill the space between the screen bracket and the lens barrel to seal and fix. UV glue needs to be cured with UV light. During the assembly process, after the position of the screen bracket and the lens barrel is determined, use UV light to irradiate the UV glue to achieve the purpose of rapid curing, but only the external part irradiated by the UV light is cured. Due to the obstruction of the structural parts, the UV glue inside the lens barrel cannot be irradiated by the UV light, resulting in the failure of the internal UV glue to cure. The uncured part of the UV glue will be heated to produce volatiles during the high temperature test of the reliability test. The volatiles will diffuse inside the lens and eventually contaminate the screen and lens surface.

[0004] Therefore, developing a lens module and an electronic product in which the UV glue will not volatilize at high temperatures after installation, thereby avoiding contamination of the screen and the lens, is a technical problem that needs to be solved urgently. Utility Model Content

[0056] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. In the description of the implementation method, specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0059] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0060] In this embodiment, if Figures 1 to 10As shown, it relates to a lens module, which includes a lens barrel 100, a screen assembly 200 and a UV glue sealing part 300. The UV glue sealing part 300 is used for sealing between the lens barrel 100 and the screen assembly 200.

[0061] In some embodiments of the present application, the lens barrel 100 includes a lens barrel body 110 and a glue groove portion 120 .

[0062] The lens barrel body 110 has a first end and a second end that are opposite to each other. The adhesive groove 120 is disposed around the first end of the lens barrel body 110. The second end of the lens barrel body 110 is used to mount the lens 130.

[0063] The screen assembly 200 includes a screen bracket 210 .

[0064] The screen bracket 210 is used to install the screen 220 .

[0065] The screen bracket 210 includes an annular light-transmitting portion 211 , and the annular light-transmitting portion 211 is circumferentially extended along the outer edge of the screen bracket 210 .

[0066] The screen bracket 210 is connected to a first end of the lens barrel body 110 . A first annular gap 410 is formed between the annular light-transmitting portion 211 and the glue groove portion 120 .

[0067] The UV adhesive sealing part 300 is filled in the first annular gap 410 . The UV adhesive sealing part 300 is used to seal the first annular gap 410 .

[0068] UV light is irradiated onto the UV glue sealing part 300 through the annular light-transmitting part 211 to cure the UV glue sealing part 300, thereby completely curing the UV glue sealing part 300 and preventing the UV glue that is not completely cured from volatilizing during the high temperature test and causing contamination to the lens 130 and the screen 220.

[0069] The screen support 210 further includes a screen support body 212 . The annular light-transmitting portion 211 is disposed around the screen support body 212 .

[0070] The screen support body 212 is made of non-light-transmitting material.

[0071] When the UV light is irradiated on the screen bracket 210 , the UV light can be irradiated through the annular light-transmitting portion 211 and irradiated on the UV glue sealing portion 300 , so that the UV glue sealing portion 300 can be fully cured.

[0072] Since the screen support body 212 is made of non-light-transmitting material, UV light can be prevented from entering the lens barrel.

[0073] Since the adhesive groove portion 120 is disposed around the first end of the lens barrel body 110 , the lens 130 is disposed at the second end of the lens barrel body 110 .

[0074] The screen assembly 200 is connected to the first end of the lens barrel body 110 , and is at least used to prevent light from entering the screen bracket 210 and irradiating the lens 130 .

[0075] Since the screen support body 212 is made of a non-light-transmitting material, the screen support body 212 is used to prevent light from entering into the lens barrel 100 .

[0076] In order to prevent light from entering the lens barrel body 110 through the annular light-transmitting portion 211, the glue groove portion 120 is formed on the first flange 111 bent outward along the first end of the lens barrel body 110; the annular light-transmitting portion 211 is formed on the second flange 213 bent outwardly by the screen assembly 200.

[0077] Specifically, the first flange 111 and the second flange 213 both protrude outward.

[0078] Specifically, the outer edge of the first flange 111 protrudes out of the second flange 213 .

[0079] Since the first annular gap 410 is arranged around the first end of the lens barrel body 110, and the first annular gap 410 is covered by the annular light-transmitting portion 211 made of a light-transmitting material, there is a possibility that light can pass through the annular light-transmitting portion 211 and the first annular gap 410 and enter the lens barrel body 110. If the light enters the lens barrel body 110, it will affect the photographer when observing during the shooting process.

[0080] To solve this technical problem, in some embodiments of the present application, an annular light blocking portion 214 is formed and extends around the inner side of the annular light transparent portion 211 , and the annular light blocking portion 214 is extended around the inner side of the annular light transparent portion 211 .

[0081] Specifically, the annular light shielding portion 214 is extended and formed on a side of the screen support body 212 close to the lens barrel 100 .

[0082] The annular light blocking portion 214 can block light from passing through the annular light transmitting portion 211 and the first annular gap 410 and entering into the lens barrel body 110 .

[0083] Therefore, the annular light blocking portion 214 is made of a non-light-transmitting material.

[0084] In some embodiments of the present application, a second annular gap 420 is formed between the annular light shielding portion 214 and the adhesive groove portion 120. The second annular gap 420 is used for relative movement between the lens barrel 100 and the screen assembly 200 during relative position adjustment between the lens barrel 100 and the screen assembly 200.

[0085] In some embodiments of the present application, the first annular gap 410 and the second annular gap 420 are connected to each other. The second annular gap 420 is formed inside the second annular gap 410.

[0086] During the production process of the lens module, in order to ensure that the positions of the lens barrel 100 and the screen assembly 200 are more accurate, the active alignment device (AA device for short) is generally used to adjust them. When the device is working, the lens barrel 100 is generally fixed first, and glue is injected into the glue groove 120 on the lens barrel 100. Then the AA device grabs the screen bracket 210 and puts it into the glue groove 120 of the lens barrel 100. After the camera captures the display center of the screen and the center of the lens 130, the position of the screen bracket (X / Y / Z direction) is adjusted by the manipulator, and finally the center of the screen and the center of the lens 130 are aligned. In this process, since the lens barrel 100 and the screen assembly 200 need to move relative to each other, a first annular gap 410 and a second annular gap 420 that are interconnected are formed between the lens barrel 100 and the screen assembly 200.

[0087] In some embodiments of the present application, there is a possibility of glue overflow during the process of filling the UV glue sealing part 300 into the first annular gap 410 and during the process of curing the UV glue sealing part 300. Therefore, the annular light-transmitting part 211 includes an annular horizontal extension part 2111, and the UV glue sealing part 300 forms an annular horizontal glue overflow part 310 during the glue overflow process.

[0088] The annular horizontal glue overflow portion 310 is formed and extended along the gap between the annular horizontal extending portion 2111 and the glue groove portion 120 .

[0089] In order to prevent the UV glue sealing portion 300 from overflowing out of the first annular gap 410 , the annular horizontal extending portion 2111 extends to a position closer to the axial direction of the lens barrel 100 relative to the annular horizontal glue overflow portion 310 .

[0090] In some embodiments of the present application, the annular light-transmitting portion 211 further includes an annular vertical extending portion 2112 . The annular vertical extending portion 2112 is disposed around the outer side of the annular horizontal extending portion 2111 .

[0091] A first annular groove 121 and a second annular groove 122 are formed around the adhesive groove portion 120 . The first annular groove 121 is arranged around the outer side of the second annular groove 122 .

[0092] The annular vertical extension portion 2112 is inserted into the first annular groove 121 to form a first annular gap 410 .

[0093] The annular light shielding portion 214 is inserted into the second annular groove 122 to form a second annular gap 420 .

[0094] In some other embodiments of the present application, there is also an electronic product, which includes the above-mentioned lens module.

[0095] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the above embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the above embodiments, or to replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions claimed to be protected by the present invention.
