Description

Technical Field

[0001] The present disclosure relates to the technical field of cameras, and particularly to a camera module, a method for manufacturing the camera module, and an electronic device. Background Art

[0002] A camera module is an important component in a terminal device. The camera module includes a base for fixing a lens module and a housing for protecting the lens module.

[0003] Currently, due to limitations in the assembly process or the accuracy of the sizes of various components in the camera, the airtightness of the camera module is poor. Based on this, when the environment where the electronic device is located changes greatly, for example, when the electronic device enters a warm indoor environment from a cold outdoor environment, the moisture in the air entering the inside of the camera housing will liquefy and adhere to the lenses in the lens module, generating water mist, which affects the use of the camera module and thus affects the user experience.

[0067] Here, the exemplary embodiments will be described in detail, and the examples are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0068] Reference Figures 1 to 3 , Figure 1 is a schematic structural diagram of a camera module provided according to an exemplary embodiment; Figure 2It is an assembly diagram of a first housing and a base shown according to an exemplary embodiment; Figure 3 It is an assembly diagram of a first housing, a lens module and a base shown according to an exemplary embodiment. Refer to Figures 1 to 3 , the camera module includes:

[0069] Base 11;

[0070] A first housing 12, located on one side of the base 11, forming an accommodation space with the base 11;

[0071] A lens module 13, located within the accommodation space;

[0072] A second housing 14, within which the base 11, the first housing 12 and the motor are located;

[0073] A first seal 15, formed at the contact position between the first housing 12 and the base 11, configured to seal a first gap between the first housing 12 and the base 11;

[0074] A second seal, formed in a second gap between an outer sidewall of a portion of the first housing 12 adjacent to the base 11 and an inner sidewall of the second housing 14.

[0075] It can be understood that the above-mentioned base 11 is used to fix the lens module 13 in the camera module, and the first housing 12 and the base 11 are assembled around the lens module 13 to protect the lens module 13 from external impacts.

[0076] In some embodiments, the shape and size of the base 11 can be determined as needed, and the embodiments of the present disclosure do not limit this.

[0077] Exemplarily, the shape of the base 11 can be set to a rectangular shape, a square shape, a circular shape, an elliptical shape, etc.

[0078] Exemplarily, considering that the lens module 13 is fixed on the base 11, therefore, the shape and size of the base 11 can also be determined according to the shape and size of the lens module 13.

[0079] In some embodiments, a metal substrate can also be assembled on a first plane of the base 11. The metal substrate can be used as a heat dissipation component of the camera module, which is beneficial for the camera motor to dissipate heat to the outside. In addition, conductive circuits can be integrated inside the metal substrate to achieve specific circuit functions.

[0080] In some embodiments, the material of the base 11 can also be set according to actual needs, and the embodiments of the present disclosure do not make specific limitations on this.

[0081] Exemplarily, the material for manufacturing the base 11 can be a metal material or an alloy material, or can also be a non-metal material. For example, a thermoplastic resin material.

[0082] In the embodiments of the present disclosure, when the material of the base 11 is metal, since the metal has good thermal conductivity, the camera module can be cooled by the base 11 made of metal. When the material of the base 11 is a thermoplastic resin material, since the thermoplastic material is easy to process and has a light weight, the overall camera module can be made lighter.

[0083] In some embodiments, the first housing 12 is located on the second plane of the base 11, where the second plane and the first plane are two opposite planes on the base 11.

[0084] In some embodiments, the size and shape of the first housing 12 can also be designed as needed, and the embodiments of the present disclosure do not limit this.

[0085] Exemplarily, the size of the first housing 12 can be determined according to the size of the lens module 13 so that at least the lens module 13 in the retracted state can be completely accommodated in the first housing 12.

[0086] Exemplarily, the shape of the first housing 12 can be set according to the shape of the base 11 so that the first housing 12 cooperates with the base 11.

[0087] For example, the size of the opening of the first housing 12 close to the base 11 is designed to be the same as the size of the second plane of the base 11.

[0088] Exemplarily, the shape of the first housing 12 can be a cylinder, a frustum of a cone, a trapezoidal prism, a square, etc. with upper and lower openings.

[0089] In some embodiments, the material of the first housing 12 can also be set as needed, and the embodiments of the present disclosure do not make specific limitations on this.

[0090] Exemplarily, the material of the first housing 12 can be a metal material, an alloy material, and a non-metal material with a certain hardness.

[0091] For example, the material of the first housing 12 can be iron, an iron alloy, or a hard plastic.

[0092] In some embodiments, the first housing 12 can be integrally formed during the manufacturing process.

[0093] In other embodiments, the first housing 12 can also be formed by enclosing a plurality of first side plates.

[0094] For example, referring to Figures 1 to 3 , the first housing 12 can be formed by enclosing four first side plates.

[0095] In some embodiments, the first housing 12 includes a third opening 121 and a fourth opening 122, wherein the third opening 121 and the fourth opening 122 are oppositely arranged. The first housing 12 contacts the base through a portion near the third opening 121, and the fourth opening 122 of the first housing is for the lens in the lens module 13 to enter and exit.

[0096] In the embodiments of the present disclosure, the first housing 12 is made of a metal material or a non-metal material with a certain hardness, which can play a certain protective role for the lens module 13 and reduce the probability of damage to the lens module 13 when the camera module is subjected to an external force.

[0097] In addition, placing the lens in the accommodation space formed by the first housing 12 and the base 11 can also reduce the interference of the external environment on the working process of the lens module 13, thereby ensuring the normal use of the lens module 13.

[0098] In some embodiments, the second housing 14 is assembled on the outer peripheries of the first housing 12 and the base 11, so that the base 11 and the first housing 12 are located in the accommodation space of the second housing 14.

[0099] In some embodiments, since both the first housing 12 and the base 11 are located inside the second housing 14, the inner diameter of the second housing 14 is greater than the outer diameters of the first housing 12 and the base 11.

[0100] In some embodiments, the shape of the first housing 12 can be designed according to the outer contour shape of the first housing 12 and the outer contour shape of the base 11 to reduce the gap between the first housing 12 and the second housing 14, thereby reducing the overall volume of the camera module.

[0101] Exemplarily, when the outer contour shape of the first housing 12 is square, the inner contour of the second housing 14 can be set to be square, and when the outer contour of the first housing 12 is cylindrical, the inner contour of the second housing 14 is also set to be cylindrical.

[0102] In some embodiments, the outer contour shape of the second housing 14 can also be set according to the internal space of the electronic device to which the camera module is to be assembled, so as to reduce the influence of the camera module on other components in the electronic device.

[0103] In some embodiments, the material of the second housing 14 can be set as needed, and the embodiments of the present disclosure do not limit this.

[0104] Exemplarily, the second housing 14 may include: a metal material, an alloy material or a non-metal material.

[0105] For example, the preparation material of the second housing 14 can be a synthetic resin with a certain hardness, or a material with a certain electromagnetic shielding effect, etc.

[0106] In the embodiments of the present disclosure, by making the second housing 14 with a material having electromagnetic shielding effect, the probability that the camera module is affected by electromagnetic interference from other electronic components can be reduced.

[0107] In some embodiments, the metal electrode plate can also be assembled in the accommodation space of the second housing 14, so that the second housing 14 can also play a protective role for the metal substrate.

[0108] In some embodiments, the above-mentioned first seal 15 and second seal can be two independent seals.

[0109] Among them, two independent seals can be understood that any one of the two seals can be replaced independently without affecting the other seal.

[0110] In other embodiments, the above-mentioned first seal 15 and second seal can be two parts of the same seal.

[0111] Exemplarily, the first seal 15 can be the horizontal part of an L-shaped seal, and the second seal can be the vertical part of the L-shaped seal.

[0112] In some embodiments, the shape of the above-mentioned first seal 15 can be designed according to the shape of the first gap between the first housing 12 and the base 11.

[0113] Exemplarily, when the shape of the first gap is a ring, the shape of the first seal 15 can also be set as a ring shape.

[0114] In some embodiments, there are various reasons for the gap between the first housing 12 and the base 11. Exemplarily, it may be due to manufacturing processes or other reasons that the base 11 or the first housing 12 is uneven, and then when the base 11 and the first housing 12 are assembled, the base 11 and the first housing 12 cannot be completely fitted to generate a gap. Therefore, the first seal 15 can be made of an elastic material, so that the first seal 15 can fill the first gap between the base 11 and the first housing 12, thereby reducing the gas from flowing through the first gap between the first housing 12 and the base 11 into the accommodation space surrounded by the first housing 12 and the base 11, and improving the airtightness between the base 11 and the first housing 12.

[0115] In some embodiments, the materials of the first seal 15 and the second seal can be rubber, graphite or a foaming composition that can generate a sealing foam.

[0116] In the embodiments of the present disclosure, by forming a first seal 15 in the first gap between the first housing 12 and the base 11 to fill the gap between the base 11 and the first housing 12, the sealing effect between the first housing 12 and the base 11 can be improved, the probability of air entering the interior of the first housing 12 from the gap between the first housing 12 and the base 11 can be reduced, and thus the probability of water mist appearing on the lens can be reduced, enhancing the user experience.

[0117] In some embodiments, the seal located in the second gap may further cover the joint between the outer sidewall of the first housing 12 and the outer sidewall of the base 11, further improving the sealing performance between the first housing 12 and the base 11.

[0118] In addition, when the second seal formed in the second gap is an elastic seal, it can also buffer the external force acting on the second housing 14 when the second housing 14 is subjected to an external force, so as to reduce the damage of the external force to the first housing 12 and the lens module 13 inside the first housing 12.

[0119] In some embodiments, the first seal 15 is formed by curing an adhesive located in the first gap;

[0120] The second seal is formed by curing an adhesive located in the second gap;

[0121] Wherein, during the process of the second housing 14 moving towards the base 11 under the action of an external force, the adhesive attached to the outer sidewall of the first housing 12 is extruded into the first gap.

[0122] It can be understood that adhesives can be filled in the first gap and the second gap, so that the cured adhesives can form the first seal 15 and the second seal, achieving the purpose of sealing the first gap between the first housing 12 and the base 11 and the second gap between the first housing 12 and the second housing 14.

[0123] In some embodiments, referring to Figure 1 , during the process of assembling the camera module, after the assembly of the first housing 12 and the base 11 is completed, an adhesive 16 can be attached to a partial area of the outer sidewall of the first housing 12 close to the base 11. During the process of assembling the second housing 14, when the second housing 14 moves towards the base 11 under the action of an external force, the adhesive 16 will be extruded into the first gap. Based on this, the adhesive located in the first gap can form the first seal 15 after curing, and the adhesive staying in the second gap can form the second seal after curing.

[0124] Exemplarily, referring to Figure 3 , an adhesive 16 can be applied in the Figure 3 dashed-line area shown.

[0125] The type of adhesive used in the embodiments of the present disclosure can be set as needed, and the embodiments of the present disclosure do not limit this.

[0126] Exemplarily, the adhesive used in the embodiments of the present disclosure can be a thermosetting adhesive, which has the characteristic of not curing at room temperature and curing after high-temperature heating. For example, epoxy resin glue.

[0127] In some embodiments, the adhesive attached to the outer sidewall of the first housing 12 can be an adhesive with poor fluidity. For example, a semi-solid adhesive. This can make the adhesive attach a certain thickness to the outer sidewall of the first housing 12.

[0128] Exemplarily, the adhesive attached to the outer sidewall of the first housing 12 can also be a photoresist.

[0129] In the embodiments of the present disclosure, during the assembly process of the camera module, by extruding the adhesive attached to the outer sidewall of the first housing 12 through the second housing 14, the adhesive can be extruded into the first gap. Compared with separately manufacturing and installing the first seal 15 and the second seal, while ensuring the sealing effect, the sealing process can also be simplified.

[0130] In addition, since in the embodiments of the present disclosure, the first gap between the first housing and the base is sealed by the adhesive, therefore, a smaller gap can be reserved between the first housing and the second housing, which can also reduce the overall volume of the camera.

[0131] In some embodiments, the second housing 14 includes a plurality of second side plates, and the plurality of second side plates enclose to form the second housing 14.

[0132] In some embodiments, each of the plurality of second side plates includes a first part and a second part. The second part is located at the end of the first part, and two adjacent second side plates are connected by the second part. A partial area of the first part of each second side plate close to the base 11 is recessed towards the inside of the second housing 14 to form a groove 141. The gap between the bottom of the groove 141 and the first housing 12 is smaller than the gap between the second part of each second side plate and the first housing 12. Based on this, when assembling the second housing 14, the adhesive attached to the outer sidewall of the first housing 12 can be extruded into the first gap through the bottom of the groove.

[0133] In another embodiment, the second housing 14 can be integrally formed. When the second housing 14 is integrally formed, a partial area of each sidewall of the second housing 14 close to the base 11 is recessed towards the inside of the second housing 14 to obtain the groove 141.

[0134] In some embodiments, the thickness of the adhesive attached to the outer sidewall of the first housing 12 is greater than the thickness of the second gap.

[0135] In some embodiments, the thickness of the adhesive 16 attached to the outer sidewall of the first housing 12 can be determined according to the size of the first gap.

[0136] Exemplarily, when the first gap is relatively large, a relatively thick adhesive 16 can be applied to the outer sidewall of the first housing 12, so that the second housing 14 can squeeze more adhesive 16 into the first gap, improving the sealing effect of the first gap between the first housing 12 and the base 11.

[0137] In some embodiments, the second housing 14 includes:

[0138] A first opening 142, and the inner sidewall of the second housing 14 near the first opening 142 contacts a part of the outer sidewall of the first housing 12;

[0139] The camera module further includes:

[0140] A third seal 17 formed between the inner sidewall of the second housing 14 near the first opening 142 and a part of the outer sidewall of the first housing 12, for sealing the third gap between the inner sidewall of the second housing 14 near the first opening 142 and a part of the outer sidewall of the first housing 12.

[0141] It can be understood that the second housing 14 further has a first opening 142 and a second opening 143, wherein the first opening 142 and the second opening 143 are oppositely arranged. Based on this, when the second housing 14 is sleeved on the outer periphery of the first housing 12 and the base 11, the inner sidewall of the second housing 14 near the first opening 142 contacts the outer sidewall of the first housing 12, and the inner sidewall of the first housing 12 near the second opening 143 contacts the sidewall of the base 11. Due to the limitations of the manufacturing process or the assembly process of the first housing 12 and the second housing 14, there is a third gap between the inner sidewall of the second housing 14 near the first opening and a part of the outer sidewall of the first housing 12. The third seal 17 in the camera module can be formed between the inner sidewall of the second housing 14 near the first opening 142 and a part of the outer sidewall of the first housing 12, for sealing the third gap between the inner sidewall of the second housing 14 near the first opening 142 and a part of the outer sidewall of the first housing 12.

[0142] In some embodiments, the shape of the third seal 17 can be set according to the shape of the first opening 142.

[0143] Exemplarily, when the first opening is a circular opening, the third seal 17 can be designed as a ring with an outer diameter the same as or close to the outer diameter of the first opening 142.

[0144] Among them, the material for manufacturing the third seal 17 can refer to the materials for manufacturing the first seal 15 and the second seal described above, and the embodiments of the present disclosure will not elaborate on this here.

[0145] In some embodiments, the third seal 17 is formed by curing an adhesive filled in the third gap.

[0146] It can be understood that an adhesive can also be filled between the inner side wall of the second housing 14 near the first opening 142 and a part of the outer side wall of the first housing 12, and the adhesive is cured. At this time, the cured adhesive can be used as the third seal 17.

[0147] Reference Figure 1 , the shape of the adhesive filled in the third gap after curing is as shown by the third seal 17 in Figure 1 .

[0148] In the embodiments of the present disclosure, since the adhesive has fluidity, it can fill the entire third gap. By sealing the gap between the inner side wall of the second housing 14 near the first opening 142 and a part of the outer side wall of the first housing 12 with the cured adhesive, the sealing effect between the first housing 12 and the second housing 14 can be improved.

[0149] In some embodiments, the first housing 12 includes:

[0150] A plurality of first side plates, which enclose to form the first housing 12, and there is an included angle between adjacent two first side plates;

[0151] A fourth seal 18 is formed at the contact position between the included angle of adjacent two first side plates and the base 11.

[0152] It can be understood that when the first housing 12 is formed by enclosing a plurality of first side plates, the adhesive 16 attached to a part of the outer side wall of the first housing 12 near the base 11 is attached to the outer side walls of each first side plate near the base 11. Based on this, when the adhesive 16 attached to the outer side walls of each first side plate near the base 11 is squeezed into the first gap by the second housing 14, the contact position between the included angle of adjacent two first side plates and the substrate may not be completely filled with the adhesive. Therefore, a fourth seal 18 can also be formed at the contact position between the included angle of adjacent two first side plates and the base 11, and the contact position between the included angle of adjacent two first side plates and the base 11 is further sealed by the fourth seal 18 to enhance the sealing performance between the first housing 12 and the base 11.

[0153] In some embodiments, the number of the first side plates enclosing the first housing 12 can be set as needed, and the embodiments of the present disclosure do not limit this.

[0154] Exemplarily, referenceFigures 1 to 3 , the first housing 12 can be formed by enclosing with four first side plates.

[0155] In some embodiments, the shape of the first side plates used to enclose and form the first housing 12 can be set as needed, and the embodiments of the present disclosure do not limit this.

[0156] Exemplarily, the first side plates used to enclose and form the first housing 12 can be flat plates or special-shaped plates.

[0157] For example, referring to Figures 1 to 3 , the two ends of the first side plate can be designed to be arc-shaped, and adjacent two first side plates are connected through an arc portion.

[0158] In another embodiment, the first housing 12 can also be integrally formed. At this time, the above-mentioned multiple first side plates can be multiple side walls of the first housing 12.

[0159] In the embodiments of the present disclosure, the integrally formed first housing 12 can further improve the sealing effect of the first housing 12.

[0160] In some embodiments, the fourth seal 18 is formed by curing the adhesive that enters the first side plate and the base 11 through the fourth gap at the angle between adjacent two first side plates.

[0161] In some embodiments, when each second side plate of the second housing 14 has a groove 141 with the bottom facing the inside of the second housing 14, there is a relatively large gap between the second part of each second side plate of the second housing 14 and the first side plate. As a result, there is a relatively large fourth gap between the angle between adjacent two first side plates and the second part of the second side plate. Based on this, the adhesive can be applied to the contact position between the angle between two adjacent first side plates and the base 11 from the fourth gap, and the adhesive that enters the contact position between the angle between two adjacent first side plates and the base 11 from the fourth gap is cured to obtain the fourth seal 18.

[0162] In some embodiments, the first gap is formed between the non-angle positions of adjacent two first side plates and the base 11.

[0163] Exemplarily, referring to Figure 3 , the first gap can be Figure 3 the gap between the first side plate directly below the dotted area in

[0164] Referring to Figure 4 , Figure 4 is a schematic flowchart of a method for manufacturing a camera module according to an exemplary embodiment. The embodiments of the present disclosure also provide a method for manufacturing a camera module, and this method includes:

[0165] S401: Assemble the second housing around the base, the first housing, and the outer periphery of the lens module; wherein, after the assembly of the second housing is completed, the base and the first housing are located inside the second housing, and the lens module is located in the accommodation space formed by the assembly of the base and the first housing;

[0166] S402: Form a first seal for the first gap between the first housing and the base;

[0167] S403: Form a second seal for the second gap between the outer sidewall of the part of the first housing close to the base and the inner sidewall of the second housing.

[0168] In some embodiments, the method for manufacturing the camera module provided by the present disclosure can be used to manufacture the camera module provided in any of the above embodiments.

[0169] In some embodiments, the assembly of the lens module 13 and the base 11 can be performed first, and then, the first housing 12 is assembled around the lens module 13 so that the lens module 13 is located in the accommodation space between the base 11 and the first housing 12. After the assembly of the first housing 12 is completed, the second housing 14 is assembled around the base 11, the first housing 12, and the lens module 13.

[0170] In some embodiments, the first seal 15 and the second seal can be seals that have been cured and formed before entering the first gap and the second gap; the first seal 15 and the second seal can also be seals formed by curing a liquid or semi-solid sealing material after entering the first gap and the second gap.

[0171] When the first seal 15 and the second seal are seals that have been cured and formed before entering the first gap and the second gap, during the process of assembling the first housing 12 and the base 11, the first seal 15 can be set between the sidewall of the first housing 12 close to the first opening 142 and the base 11, and before assembling the second housing 14, the second seal is covered on the outer sidewall of the part of the first housing 12 close to the base 11.

[0172] When the first seal 15 and the second seal are seals formed by curing a liquid or semi-solid sealing material after entering the first gap and the second gap, after the first housing 12 is assembled on the base 11, the sealing material can be attached to the outer sidewall of the first housing 12 close to the base 11. And after the assembly of the second housing 14 is completed, the liquid or semi-solid sealing material attached to the outer sidewall of the first housing 12 close to the base 11 is cured to obtain the first seal 15 and the second seal.

[0173] In some embodiments, the first seal 15 that forms the first gap between the first housing 12 and the base 11 includes:

[0174] Before assembling the second housing 14, attach the adhesive 16 to the outer sidewall of the portion of the first housing 12 near the base 11;

[0175] When assembling the second housing 14, during the process of the second housing 14 moving towards the base 11 under the action of an external force, the adhesive 16 attached to the outer sidewall of the portion of the first housing 12 near the base 11 is extruded into the first gap;

[0176] Cure the adhesive 16 located in the first gap to form the first seal 15.

[0177] In some embodiments, the liquid or semi-solid sealing material attached to the outer sidewall of the first housing 12 near the base 11 can be an adhesive. Based on this, before assembling the second housing 14, the adhesive can be applied to the outer sidewall of the portion of the first housing 12 near the base 11. During the process of assembling the second housing 14, when the second housing 14 moves towards the base 11 under the action of an external force, the adhesive 16 attached to the outer sidewall of the portion of the first housing 12 near the base 11 can be extruded into the first gap. After that, the adhesive located in the first gap can be cured to form the first seal 15.

[0178] In some embodiments, referring to Figure 3 , the adhesive can be applied to the dotted area of the outer sidewall of the first housing 12.

[0179] In some embodiments, when each sidewall or each second side plate of the second housing 14 has a groove 141, the adhesive 16 can be applied to the outer sidewall area of the first housing 12 corresponding to the bottom of the groove 141. Based on this, when assembling the second housing 14, the adhesive attached to the outer sidewall of the first housing 12 can be extruded into the first gap through the bottom area of the groove 141 on the second housing 14.

[0180] In some embodiments, the thickness of the adhesive attached to the outer sidewall of the portion of the first housing 12 near the base 11 is greater than the thickness of the second gap.

[0181] In some embodiments, the thickness of the adhesive attached to the outer sidewall of the first housing 12 can be determined according to the first gap.

[0182] Exemplarily, when the first gap is relatively large, apply a thicker adhesive to the outer sidewall of the first housing 12, so that the second housing 14 can extrude more adhesive 16 into the first gap, improving the sealing effect on the first gap between the first housing 12 and the base 11.

[0183] In some embodiments, S403 includes:

[0184] Cure the adhesive in the second gap to obtain a second seal.

[0185] It can be understood that during the process of the second housing 14 squeezing the adhesive 16 attached to the outer sidewall of the first housing 12 into the first gap, part of the adhesive 16 will still adhere to the outer sidewall of the first housing 12. Based on this, curing the adhesive still adhering to the outer sidewall of the first housing 12 can form a second seal.

[0186] In some embodiments, the method further includes:

[0187] After completing the assembly of the second housing 14, form a third seal 17 between the inner sidewall of the second housing 14 near the first opening and the first housing 12.

[0188] It can be understood that due to the limitations of the manufacturing process or assembly process of the first housing 12 and the second housing 14, there is still a third gap between the inner sidewall of the second housing 14 near the first opening and a part of the outer sidewall of the first housing 12. Therefore, a third seal 17 can also be formed between the inner sidewall of the second housing 14 near the first opening and a part of the outer sidewall of the first housing 12 to seal the third gap between the inner sidewall of the second housing 14 near the first opening and a part of the outer sidewall of the first housing 12.

[0189] In some embodiments, if the third seal 17 is a pre-formed seal before entering the third gap, then during the assembly of the second housing 14, the third seal 17 can be placed between the inner sidewall of the first opening of the second housing 14 and a part of the outer sidewall of the first housing 12.

[0190] In other embodiments, if the third seal 17 is a seal formed by curing after entering the third gap, then after completing the assembly of the second housing 14, a liquid or semi-solid sealing material can be applied to the third gap, and the liquid or semi-solid sealing material in the third gap can be cured to obtain the third seal 17.

[0191] Reference Figure 5 , Figure 5 is a flowchart showing a method for manufacturing a camera module according to another exemplary embodiment. In some embodiments, forming a third seal between the inner sidewall of the second housing near the first opening and the first housing includes:

[0192] S501: Fill the third gap between the inner sidewall of the second housing near the first opening and the first housing with an adhesive;

[0193] S502: Cure the adhesive filled in the third gap to obtain a third seal.

[0194] In some embodiments, when the above-mentioned liquid or semi-solid sealing material is an adhesive, after the assembly of the second housing 14 is completed, the adhesive can be filled into the third gap between the inner sidewall of the first housing 12 near the first opening 142 and a part of the outer sidewall of the first housing 12. After the filling of the adhesive is completed, the adhesive in the third gap is cured to form the third seal 17.

[0195] Exemplarily, referring to Figure 1 , the adhesive in the third gap can form the third seal 17 shown in Figure 1 .

[0196] In some embodiments, the method further includes:

[0197] After the adhesive in the first gap and / or the third gap is cured, the camera module is flipped;

[0198] A fourth seal 18 is formed at the contact position between the included angle of two adjacent first side plates of the first housing 12 and the base 11.

[0199] It can be understood that when the adhesive attached to the outer sidewall of each first side plate near the base 11 is squeezed into the first gap through the second housing 14, the contact position between the included angle of two adjacent first side plates and the substrate may not be completely filled with the adhesive. Therefore, after the adhesives in the first gap and the second gap are cured, the camera module can be flipped, and a fourth seal 18 is formed at the contact position between the included angle of two adjacent first side plates and the base 11. By further sealing the contact position between the included angle of two adjacent first side plates and the base 11 through the fourth seal 18, the sealing effect between the first housing 12 and the base 11 can be further improved.

[0200] In some embodiments, forming the fourth seal 18 at the contact position between the included angle of two adjacent first side plates of the first housing 12 and the base 11 includes:

[0201] Filling the adhesive from the fourth gap between the included angle of two adjacent first side plates of the first housing 12 and the second housing 14 into the contact position between the first side plate and the base 11;

[0202] Curing the adhesive that enters the contact position between the first side plate and the base 11 from the fourth gap to form the fourth seal 18.

[0203] Exemplarily, referring to Figure 1 , the adhesive that enters the contact position between the first side plate and the base 11 from the fourth gap can form the fourth seal 18 after curing.

[0204] In some embodiments, when the fourth gap is relatively narrow, an adhesive can also be directly filled into the fourth gap, and the adhesive filled into the fourth gap is cured. The cured adhesive in the fourth gap can cover the contact position between the included angle of two adjacent first side plates and the base 11, so as to also achieve the purpose of sealing the contact position between the included angle of two adjacent first side plates and the base 11.

[0205] Exemplarily, referring to Figures 1 to 3 , when the first housing 12 is formed by enclosing four first side plates, there are four included angles between the first housing 12 and the base 11. After curing the adhesive in the first gap and / or the second gap, the camera module can be flipped, and adhesives are filled into the contact positions between the four included angles and the base 11 to form four fourth seals 18.

[0206] In some embodiments, curing the adhesive includes:

[0207] Performing ultraviolet (UV) exposure treatment on the adhesive;

[0208] And / or;

[0209] Heating the adhesive.

[0210] In some embodiments, after each filling of the adhesive as described above is completed, the camera module can be directly moved into an oven, and the adhesive is heated and cured by heating.

[0211] For example, after filling the adhesives in the first gap, the second gap, and the third gap, the camera module can be directly moved into an oven, and the adhesives in the first gap, the second gap, and the third gap are heated and cured by heating.

[0212] It should be noted that if the oven is used to directly heat and cure the adhesive, during the process of moving the camera module into the oven, the positions of the first housing and the second housing can be fixed by an external force, reducing the problem that the positions of the first housing and the second housing move during the process of moving the camera module, resulting in poor precision of the camera module assembly.

[0213] In some other embodiments, UV exposure treatment can also be performed on the adhesive after each filling of the adhesive is completed to cure the adhesive.

[0214] For example, after filling the adhesives in the first gap, the second gap, and the third gap, UV exposure treatment is performed on the adhesives in the first gap, the second gap, and the third gap to cure the adhesives.

[0215] In some other embodiments, the adhesive may be preliminarily cured by ultraviolet light first, and then the camera module is moved into an oven to heat-cure the adhesive.

[0216] In some embodiments, the temperature range for heat-curing the adhesive may be from 60°C to 90°C.

[0217] In the embodiments of the present disclosure, the adhesive is first preliminarily cured by ultraviolet light, and then the camera module is moved into an oven for deep curing. Compared with directly moving the camera module into the oven to heat-cure the adhesive, it can reduce the probability that the relative movement between the unfixed components in the camera module during the process of moving the camera module into the oven affects the assembly accuracy of the camera module.

[0218] Reference Figure 6 , Figure 6 FIG. is a schematic flowchart of a method for manufacturing a camera module according to yet another exemplary embodiment. Hereinafter, the method for manufacturing the camera module provided above will be further described with a specific embodiment according to the steps shown in Figure 6 .

[0219] S601: After assembling the first housing, the base, and the lens module, an adhesive with a preset thickness is attached to the outer sidewall of a part of the first housing close to the base.

[0220] Wherein, the preset thickness is greater than the second gap between the first housing 12 and the second housing 14.

[0221] Exemplarily, the thickness of the adhesive attached to the outer sidewall of the part of the first housing 12 close to the base 11 is 1.5 to 3 times the thickness of the second gap. For example, the thickness of the adhesive attached to the outer sidewall of the part of the first housing 12 close to the base 11 is 2 times the thickness of the second gap.

[0222] S602: Assemble the second housing on the outer periphery of the first housing. Wherein, when assembling the second housing, during the process that the second housing moves towards the base under the action of an external force, the adhesive attached to the outer sidewall of the part of the first housing close to the base is extruded into the first gap.

[0223] S603: Perform UV exposure treatment on the adhesives in the first gap and the second gap.

[0224] S604: Heat-cure the adhesives in the first gap and the second gap through an oven.

[0225] S605: After the adhesives in the first gap and / or the third gap are cured, flip the camera module.

[0226] S606: Fill an adhesive at the contact position between the included angle of two first side plates adjacent to the first housing and the base.

[0227] S607: Heat and cure the adhesive filled at the contact position between the included angle of two first side plates and the base through an oven.
