It should also be understood that terms (such as terms defined in commonly used dictionaries) should be interpreted as having the same meaning as their meaning in the context of the relevant technology, and will not be interpreted in an idealized or overly formalized manner unless explicitly defined in this article.

[0037] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0038] The features, principles and other aspects of the present application are described in detail below.

[0039] During the assembly of the camera module, when the camera module needs to be heated twice or multiple times due to process selection and other reasons, the gas in the closed space of the camera module will expand due to heat, causing the air pressure in the space to increase. This will cause the photosensitive device placed in the space to be easily damaged or deformed under the action of air pressure, and the lens mount is also prone to deformation or displacement, thereby affecting the imaging of the camera module. However, if the internal space of the camera module is not sealed, water vapor, dust, etc. will enter, thereby affecting the imaging quality of the camera module.

[0040] In view of the above problems, the present invention provides a simple, convenient and safe camera module manufacturing method. Figure 1 The flowchart of the manufacturing method of the camera module of the embodiment of the present application is shown in FIG. Figure 1 As shown, the manufacturing method includes the following steps.

[0041] Step 10: Curing the first adhesive disposed between the lens holder and the substrate by heating, so that the lens holder and the substrate bonded by the cured first adhesive surround and form a receiving space with air holes.

[0042] Step 20: Add waterproof and breathable material into the vent holes.

[0043] Step 30: Curing the second adhesive disposed between the lens mount and the lens by heating, thereby bonding the lens to the lens mount.

[0044] The lens can be a single lens component or a lens assembly with a motor.

[0045] When the first adhesive is cured by heating, a vent is usually required to discharge the air in the accommodation space that expands due to heat. When the fixing between the lens mount and the substrate and the fixing between the lens mount and the lens are performed at different positions (for example, workstations), it may be necessary to move the fixed lens mount and the lens. During this movement, impurities such as dust may enter the accommodation space through the vent to affect the photosensitive device. However, if this opening is closed with an ordinary adhesive, when the lens mount needs to be reheated due to process selection and other reasons, the air in the accommodation space may cause damage to the photosensitive device or the lens mount, the substrate, etc. during the expansion process. The present application adopts a solution of filling the vent with a waterproof and breathable material. On the one hand, dust can be prevented from entering the accommodation space. On the other hand, when the camera module is reheated to cure the second adhesive, the gas expanded by heat in the accommodation space is discharged through the vent, thereby preventing the device in the accommodation space from being damaged.

[0046] In an exemplary embodiment, before curing the first adhesive by heating, the manufacturing method includes: pre-curing the first adhesive by light. The first adhesive is placed between the lens holder and the substrate, and the first adhesive is irradiated with light to give it a certain degree of adhesion, thereby preliminarily fixing the lens holder and the substrate.

[0047] In an exemplary embodiment, the first adhesive is a UV thermosetting adhesive, and the irradiation of light may be ultraviolet light.

[0048] In an exemplary embodiment, the waterproof breathable material is a waterproof breathable glue. The waterproof breathable glue is at least partially placed in the vent hole. To this end, the waterproof breathable material may be, for example, a waterproof breathable glue with a small thixotropy so as to facilitate the flow into the vent hole. When the gas in the accommodation space expands due to heat, the expanded air can be discharged through the waterproof breathable glue. In addition, the waterproof breathable glue may adopt a curing method different from the thermosetting method, such as moisture curing or light curing (e.g., UV curing).

[0049] In an exemplary embodiment, the vent hole is disposed on a side of the lens holder adjacent to the lens, and the vent hole does not overlap with the region where the second adhesive is disposed. In this case, the second adhesive and the waterproof breathable material are prevented from reacting due to contact with each other, thereby preventing the second adhesive or the waterproof breathable material from failing due to such reaction.

[0050] In an exemplary embodiment, the vent hole is disposed on a side of the lens mount adjacent to the lens, the vent hole at least partially overlaps with the area where the second adhesive is disposed, and the second adhesive has the same composition as the waterproof breathable adhesive. In this case, since the second adhesive has the same composition as the waterproof breathable adhesive, the position of the vent hole can be more selective, thereby reducing the design and processing tolerances. In addition, in this case, the size of the lens mount can be designed to be smaller, and the overall size of the module can also be made smaller.

[0051] In an exemplary embodiment, the vent hole is disposed on the side wall of the lens mount, and the side wall of the lens mount is not connected to the substrate and the lens. In this case, since the opening position of the vent hole and the position where the second adhesive is disposed are not on the same surface, the position of the vent hole can be more selective, thereby reducing the design and processing tolerances. In addition, in this case, the size of the lens mount can be designed to be smaller, and the overall size of the module can also be made smaller.

[0052] In an exemplary embodiment, the first adhesive disposed between the lens mount and the substrate forms a pattern having an opening, and the air vent is formed at the opening. The pattern may be a non-closed pattern according to the setting requirements. For example, the pattern may be an open circle or rectangle. After the lens mount is connected to the substrate, the opening forms an air vent through the cooperation of the lens mount and the substrate to form a gas escape channel.

[0053] In an exemplary embodiment, the manufacturing method further includes providing a reinforcing adhesive at the connection between the connecting belt, the lens mount and the substrate, wherein the connecting belt is used to transmit the data collected by the camera module to the external

[0054] In an exemplary embodiment, the reinforcing glue at least partially overlaps with the vent hole, and the reinforcing glue and the waterproof breathable glue have the same composition to ensure that while the reinforcing glue is used to enhance the connection strength between the lens holder and the substrate, the gas in the accommodating space can still be discharged through the vent hole.

[0055] The present application also provides a camera module obtained by the above-mentioned manufacturing method.

[0056] Example 1

[0057] Figure 2 Schematic diagram showing the structure of a camera module according to Embodiment 1 of the present application. Figure 2As shown, the camera module includes a lens holder 100, a substrate 101 and a lens 102. The lens holder 100 may include a color filter 103 and a lens holder body carrying the color filter 103. At the first station, the lens holder 100 is fixedly connected to the substrate 101 electrically connected to the photosensitive device 107 through a first adhesive 104.

[0058] A first adhesive 104 is provided at the connection between the lens holder 100 and the substrate 101. The first adhesive 104 can be pre-cured by irradiation with light. The pre-cured first adhesive 104 has a certain adhesiveness, which can initially fix the lens holder 100 and the substrate 101.

[0059] Preferably, the first adhesive 104 may be a UV thermosetting adhesive, and the first adhesive 104 may be cured by irradiating ultraviolet light. Then, the lens holder 100 and the substrate 101 after bonding are heated to cure the first adhesive 104, thereby achieving a fixed connection between the lens holder 100 and the substrate 101. Preferably, the lens holder 100 and the substrate 101 after bonding may be baked to achieve a fixed connection between the lens holder 100 and the substrate 101.

[0060] After the lens holder 100 is fixedly connected to the substrate 101 , the lens holder 100 and the substrate 101 that are fixedly connected to each other can be moved to a second station for further assembly.

[0061] Before the module is moved, a waterproof and breathable material 109 may be placed in the air hole 105. This can prevent dust from entering the accommodation space through the air hole 105 during the movement of the module.

[0062] At the second station, the lens 102 and the lens holder 100 are fixedly connected by the second adhesive 108, and the curing process is the same as the curing process in the above step. For example, the second adhesive 108 composed of UV thermosetting adhesive can be pre-cured by light, and then the second adhesive 108 can be further cured by baking. For example, in some assembly process flows, when the lens 102 and the lens holder 100 are bonded, a photo identification and alignment process is generally required. After the relative position has been aligned and the second adhesive 108 is pre-cured, the assembly is placed in an oven for baking to further cure the second adhesive 108.

[0063] Due to the provision of the waterproof breathable material 109 , during the secondary heating process, the air expanded by heat in the accommodation space 106 formed by the lens holder 100 and the substrate 101 can be discharged to the outside through the waterproof breathable material 109 .

[0064] In this embodiment, the second adhesive 108 and the waterproof breathable material 109 may be made of different components. For example, the second adhesive 108 may be made of a high-strength UV thermosetting agent, and the waterproof breathable material 109 may be made of a highly breathable waterproof breathable glue. In this case, the vent 105 may be arranged so as not to overlap with the area where the second adhesive 108 is arranged to avoid mixing of the second adhesive 108 and the waterproof breathable material 109.

[0065] In this embodiment, the vent hole 105 is disposed on a side of the lens holder 100 adjacent to the lens to be mounted, and the vent hole 105 may be disposed so as not to overlap with the area where the second adhesive 108 is disposed.

[0066] Example 2

[0067] Figure 3 Schematic diagram showing the structure of a camera module according to Embodiment 2 of the present application. Figure 3 As shown, the camera module includes a lens holder 100, a substrate 101 and a lens 102. The lens holder 100 may include a color filter plate 103 and a lens holder body carrying the color filter plate 103.

[0068] At the first station, the lens holder 100 is fixedly connected to the substrate 101 electrically connected to the photosensitive device 107 by means of a first adhesive 104 .

[0069] A first adhesive 104 is provided at the connection between the lens holder 100 and the substrate 101. The first adhesive 104 can be pre-cured by irradiation with light. The pre-cured first adhesive 104 has a certain adhesiveness, which can initially fix the lens holder 100 and the substrate 101.

[0070] Preferably, the first adhesive 104 may be a UV thermosetting adhesive, and the first adhesive 104 may be cured by irradiating ultraviolet light. Then, the lens holder 100 and the substrate 101 after bonding are heated to cure the first adhesive 104, thereby achieving a fixed connection between the lens holder 100 and the substrate 101. Preferably, the lens holder 100 and the substrate 101 after bonding may be baked to achieve a fixed connection between the lens holder 100 and the substrate 101.

[0071] After the lens holder 100 is fixedly connected to the substrate 101 , the lens holder 100 and the substrate 101 that are fixedly connected to each other can be moved to a second station for further assembly.

[0072] Before the module is moved, a waterproof and breathable material 109 may be placed in the air hole 105. This can prevent dust from entering the accommodation space through the air hole 105 during the module movement.

[0073] At the second working station, the lens 102 and the lens holder 100 are fixedly connected by a second adhesive 108 .

[0074] Due to the provision of the waterproof breathable material 109 , during the secondary heating process, the air expanded by heat in the accommodation space 106 formed by the lens holder 100 and the substrate 101 can be discharged to the outside through the waterproof breathable material 109 .

[0075] In this embodiment, the vent hole 105 can be arranged to partially overlap with the area where the second adhesive 108 is arranged, thereby improving the flexibility of the area where the vent hole is arranged to reduce the difficulty of processing. For example, the vent hole 105 is arranged on the side of the lens holder 100 adjacent to the lens to be installed, and the vent hole 105 can be arranged to at least partially overlap with the area where the second adhesive 108 is arranged. In this case, the second adhesive 108 and the waterproof breathable material 109 can use the same component, for example, both select a waterproof and breathable adhesive component. In this embodiment, the second adhesive 108 and the waterproof breathable material 109 can both use a highly breathable waterproof and breathable glue.

[0076] Example 3

[0077] Figure 4 Schematic diagram showing the structure of a camera module according to Embodiment 3 of the present application. Figure 4 As shown, the camera module includes a lens holder 100, a substrate 101 and a lens 102. The lens holder 100 may include a color filter plate 103 and a lens holder body carrying the color filter plate 103.

[0078] At the first station, the lens holder 100 is fixedly connected to the substrate 101 electrically connected to the photosensitive device 107 by means of a first adhesive 104 .

[0079] A first adhesive 104 is provided at the connection between the lens holder 100 and the substrate 101. The first adhesive 104 can be pre-cured by irradiation with light. The pre-cured first adhesive 104 has a certain adhesiveness, which can initially fix the lens holder 100 and the substrate 101.

[0080] Preferably, the first adhesive 104 may be a UV thermosetting adhesive, and the first adhesive 104 may be cured by irradiating ultraviolet light. Then, the lens holder 100 and the substrate 101 after bonding are heated to cure the first adhesive 104, thereby achieving a fixed connection between the lens holder 100 and the substrate 101. Preferably, the lens holder 100 and the substrate 101 after bonding may be baked to achieve a fixed connection between the lens holder 100 and the substrate 101.

[0081] After the lens holder 100 is fixedly connected to the substrate 101 , the lens holder 100 and the substrate 101 that are fixedly connected to each other can be moved to a second station for further assembly.

[0082] Before the module is moved, a waterproof and breathable material 109 may be placed in the air hole 105. This can prevent dust from entering the accommodation space through the air hole 105 during the module movement.

[0083] At the second station, the lens 102 and the lens holder 100 are fixedly connected by the second adhesive 108, and the curing process is the same as the curing process in the above step. For example, the second adhesive 108 composed of UV thermosetting adhesive can be pre-cured by light, and then further cured by baking.

[0084] Due to the provision of the waterproof breathable material 109 , during the secondary heating process, the air expanded by heat in the accommodation space 106 formed by the lens holder 100 and the substrate 101 can be discharged to the outside through the waterproof breathable material 109 .

[0085] In this embodiment, the air hole 105 is provided on the side wall of the lens mount 100. The side wall of the lens mount 100 is not connected to the substrate 101 and the lens 102. In this case, the waterproof breathable material 109 and the first adhesive 104 and the second adhesive 108 are provided on different surfaces. Therefore, on the one hand, the risk of the waterproof breathable material 109 mixing with the first adhesive 104 and the second adhesive 108 is reduced; on the other hand, the design flexibility of the air hole 105 on the side wall is increased. Based on this, the air hole 105 can be a through hole on the side wall of the lens mount 100, and the through hole does not contact the edge of the side wall. On the other hand, the air hole 105 can also be a notch on the bottom edge of the side wall of the lens mount 100 to reduce the difficulty of molding the lens mount 100 (not shown in the figure).

[0086] Example 4

[0087] Figure 5 1 is a schematic diagram showing the structure of a camera module according to Embodiment 4 of the present application. The overall structure of the camera module of Embodiment 4 is substantially the same as that of Embodiments 1-3, except that the position and arrangement of the air vent 105 are different. Figure 5 As shown, the first adhesive 104 disposed between the lens holder and the substrate 101 forms a pattern with openings, and the air holes 105 are formed at the openings. For example, the pattern can be a circle or rectangle with openings.

[0088] In this embodiment, the position of the vent hole 105 can be away from the connection belt 110 connected to the substrate 101, or can be on any side of the pattern formed by the first adhesive 104. The connection belt 110 can transmit the image information collected by the photosensitive device 107 to the outside in the form of an electrical signal.

[0089] The first adhesive 104 can be pre-cured by irradiation with light. The pre-cured first adhesive 104 has a certain adhesiveness, which can initially fix the lens holder 100 and the substrate 101.

[0090] Preferably, the first adhesive 104 may be a UV thermosetting adhesive, and the first adhesive 104 may be cured by irradiating ultraviolet light. Then, the lens holder 100 and the substrate 101 after bonding are heated to cure the first adhesive 104, thereby achieving a fixed connection between the lens holder 100 and the substrate 101. Preferably, the lens holder 100 and the substrate 101 after bonding may be baked to achieve a fixed connection between the lens holder 100 and the substrate 101.

[0091] After the lens holder 100 is fixedly connected to the substrate 101, a vent hole 105 is formed at the opening of the first adhesive 104. The lens holder 100 and the substrate 101 fixedly connected to each other are moved to the second station for further assembly.

[0092] Before the module is moved, a waterproof and breathable material 109 may be placed in the air hole 105. This can prevent dust from entering the accommodation space through the air hole 105 during the movement of the module.

[0093] At the second station, the lens 102 and the lens holder 100 are fixedly connected by the second adhesive 108, and the curing process is the same as the curing process in the above step. For example, the second adhesive 108 composed of UV thermosetting adhesive can be pre-cured by light, and then further cured by baking.

[0094] Due to the provision of the waterproof breathable material 109, during the secondary heating process, the air expanded by heat in the accommodation space 106 formed by the lens holder 100 and the substrate 101 can be discharged to the outside through the waterproof breathable material 109. At the same time, in this embodiment, the breathable hole 105 can be obtained without drilling a hole in the lens holder 100, saving process and cost.

[0096] Figure 6 Schematic diagram showing the structure of a camera module according to Embodiment 5 of the present application. Figure 6 As shown, the camera module includes a lens holder 100, a substrate 101 and a lens 102. The lens holder 100 may include a color filter 103 and a lens holder body carrying the color filter 103. At the first station, the lens holder 100 is fixedly connected to the substrate 101 electrically connected to the photosensitive device 107 through a first adhesive 104.

[0097] A first adhesive 104 is provided at the connection between the lens holder 100 and the substrate 101. The first adhesive 104 can be pre-cured by irradiation with light. The pre-cured first adhesive 104 has a certain adhesiveness, which can initially fix the lens holder 100 and the substrate 101.

[0098] Preferably, the first adhesive 104 may be a UV thermosetting adhesive, and the first adhesive 104 may be cured by irradiating ultraviolet light. Then, the lens holder 100 and the substrate 101 after bonding are heated to cure the first adhesive 104, thereby achieving a fixed connection between the lens holder 100 and the substrate 101. Preferably, the lens holder 100 and the substrate 101 after bonding may be baked to achieve a fixed connection between the lens holder 100 and the substrate 101.

[0099] After the lens holder 100 is fixedly connected to the substrate 101 , the lens holder 100 and the substrate 101 that are fixedly connected to each other can be moved to a second station for further assembly.

[0100] Before the module is moved, a waterproof and breathable material 109 may be placed in the air hole 105. This can prevent dust from entering the accommodation space through the air hole 105 during the module movement.

[0101] At the second station, the lens 102 and the lens holder 100 are fixedly connected by the second adhesive 108, and the curing process is the same as the curing process in the above step. For example, the second adhesive 108 composed of UV thermosetting adhesive can be pre-cured by light, and then further cured by baking.

[0102] Due to the provision of the waterproof breathable material 109 , during the secondary heating process, the air expanded by heat in the accommodation space 106 formed by the lens holder 100 and the substrate 101 can be discharged to the outside through the waterproof breathable material 109 .

[0103] In this embodiment, the vent hole 105 is disposed on the side wall of the lens mount 100. The side wall of the lens mount 100 is not connected to the substrate 101 and the lens 102.

[0104] The vent hole 105 faces a connecting belt 110 connected to the substrate 101. The connecting belt 110 can transmit the electrical signal collected by the photosensitive device 107 to the outside.

[0105] In this embodiment, in order to enhance the connection strength between the connection belt and the lens mount 100 and the substrate 101, a reinforcing glue 111 is provided at the connection between the connection belt 110 and the lens mount 100 and the substrate 101. When the composition of the reinforcing glue 111 is different from that of the waterproof breathable material 109, the coverage area of ​​the reinforcing glue 111 does not include the breathable hole 105. On the contrary, when the composition of the reinforcing glue 111 is the same as that of the waterproof breathable material 109, the reinforcing glue 111 can cover the breathable hole 105.

[0107] Figure 71 is a schematic diagram showing the structure of a camera module according to Embodiment 6 of the present application. This embodiment is substantially the same as Embodiment 4, except for the opening direction of the first adhesive 104. In this embodiment, the opening of the first adhesive 104 faces the connecting strip 110 connected to the substrate 101. The connecting strip 110 can transmit the electrical signal collected by the photosensitive device 107 to the outside.

[0108] The first adhesive 104 can be pre-cured by irradiation with light. The pre-cured first adhesive 104 has a certain adhesiveness, which can initially fix the lens holder 100 and the substrate 101.

[0109] Preferably, the first adhesive 104 may be a UV thermosetting adhesive, and the first adhesive 104 may be cured by irradiating ultraviolet light. Then, the lens holder 100 and the substrate 101 after bonding are heated to cure the first adhesive 104, thereby achieving a fixed connection between the lens holder 100 and the substrate 101. Preferably, the lens holder 100 and the substrate 101 after bonding may be baked to achieve a fixed connection between the lens holder 100 and the substrate 101.

[0110] After the lens holder 100 is fixedly connected to the substrate 101, a vent hole 105 is formed at the opening of the first adhesive 104. The lens holder 100 and the substrate 101 fixedly connected to each other are moved to the second station for further assembly.

[0111] Before the module is moved, a waterproof and breathable material 109 may be placed in the air hole 105. This can prevent dust from entering the accommodation space through the air hole 105 during the movement of the module.

[0112] At the second station, the lens 102 and the lens holder 100 are fixedly connected by the second adhesive 108, and the curing process is the same as the curing process in the above step. For example, the second adhesive 108 composed of UV thermosetting adhesive can be pre-cured by light, and then further cured by baking.

[0113] Due to the provision of the waterproof breathable material 109 , during the secondary heating process, the air expanded by heat in the accommodation space 106 formed by the lens holder 100 and the substrate 101 can be discharged to the outside through the waterproof breathable material 109 .

[0114] Similar to the fourth embodiment, in this embodiment, the air vent 105 can be obtained without drilling a hole on the lens holder 100, thus saving process steps and costs.

[0115] In addition, in this embodiment, in order to enhance the connection strength between the connection belt 110 and the lens holder 100 and the substrate 101 , a reinforcing glue 111 may be provided at the connection between the connection belt 110 and the lens holder 100 and the substrate 101 .

[0116] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the above features are replaced with the technical features with similar functions disclosed in this application (but not limited to) by each other.
