[0020] In order to better understand the present invention, various aspects of the present invention will be described in more detail with reference to the accompanying drawings. It should be understood that these detailed descriptions are only descriptions of embodiments of the present invention, and do not limit the scope of the present invention in any way. It should be noted that in this specification, the expressions of first, second, third, etc. are only used to distinguish one feature from another feature, and do not represent any limitation on the feature.

[0021] It should also be understood that the terms “comprises,” “including,” “having,” “includes” and / or “comprising,” when used in this specification, indicate the presence of stated features, elements and / or components, but do not exclude the presence or addition of one or more other features, elements, components and / or combinations thereof.

[0022] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by those skilled in the art to which the present invention belongs. It should also be understood that terms (such as those defined in commonly used dictionaries) should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and will not be interpreted in an idealized or overly formal sense unless explicitly defined in this article.

[0023] In order to facilitate the understanding of this application, the existing camera module is first explained. The camera module mainly includes two major components: a lens and a circuit board. A photosensitive chip is provided on the front of the circuit board to receive light from the lens and form an image, and an electronic device is provided on the back of the circuit board. In particular, the periscope camera module integrates many electronic devices on the back of the circuit board. The assembly of the camera module refers to assembling the lens and the circuit board together in a good alignment to ensure that the focal length of the lens and the circuit board can be in a better imaging position. During the assembly process of the camera module, the lens and the circuit board need to be fixed separately. In the existing assembly method, the circuit board is mainly fixed by vacuum adsorption of the back of the circuit board, and then the positional relationship between the circuit board and the lens is adjusted, and finally the fixation is completed by glue dosing. Then, as more and more electronic devices are integrated on the back of the circuit board of the camera module, the method of vacuum adsorption of the back of the circuit board will cause damage to the electronic devices, which is no longer applicable, so a new assembly jig and equipment are needed.

[0024] Please refer to Figure 1 The camera module includes a lens 30 to be assembled and a circuit board 40 to be assembled. The present invention provides a camera module assembly fixture including a lens fixing component 10 and a circuit board fixing component 20. The lens fixing component 10 is used to install the lens 30 to be assembled, and the circuit board fixing component 20 is used to install the circuit board 40 to be assembled. The circuit board fixing component 20 is arranged on one side of the lens fixing component 10, and is used to cooperate with the lens fixing component 10 to realize the assembly alignment of the lens 30 to be assembled and the circuit board 40 to be assembled.

[0025] Please refer to Figure 2 , Figure 2 A partial schematic diagram of the lens fixing assembly is provided to facilitate understanding of this solution. Figure 2 There are two lens fixing plates 120 provided in the figure, one lens fixing plate 120 and the lens mounting plate 110 are close to clamp the lens 30 to be assembled, and the other lens fixing plate 120 is in an open state so that the technical details can be seen clearly. Specifically, the lens fixing assembly 10 includes a lens mounting plate 110, a lens fixing plate 120 and a first magnetic member 130. The lens fixing plate 120 is rotatably mounted on the lens mounting plate 110. The first magnetic member 130 is disposed on the lens fixing plate 120. The first magnetic member 130 and the lens mounting plate 110 can drive the lens fixing plate 120 to approach the lens mounting plate 110 through magnetic attraction, so as to clamp the lens 30 to be assembled disposed on the lens mounting plate 110. For example, Figure 2The lens fixing plate 120 on the left side is in a closed state, clamping the lens 30 to be assembled on the lens mounting plate 110, and the lens fixing plate 120 on the right side is in an open state, and has not yet clamped the lens 30 to be assembled, so as to understand the technical details. It should be noted that in order to ensure the magnetic attraction between the first magnetic member 130 and the lens mounting plate 110, the lens mounting plate 110 can be made of metal, or a metal structure can be installed to cooperate with the first magnetic member 130.

[0026] Among them, since the lens fixing plate 120 is mounted on the lens mounting plate 110 by rotation, the first magnetic member 130 and the lens mounting plate 110 can generate magnetic attraction, thereby driving the lens fixing plate 120 close to the lens mounting plate 110, so as to clamp the lens 30 to be assembled between the lens fixing plate 120 and the lens mounting plate 110, and the magnetic clamping method can reduce the difficulty of installing the lens 30 to be assembled. It should be noted that magnetic attraction refers to adsorbing two objects together through the principle of magnetic attraction.

[0027] It should be noted that the rotatable installation method of the lens fixing plate 120 and the lens mounting plate 110 can be installed by any one of bearings, hinges, balls or rotating rods 140. For example, the lens fixing plate 120 is fixed to the inner ring of the bearing, and the lens mounting plate 110 is fixed to the outer ring of the bearing, so that the lens fixing plate 120 can be rotatably connected to the lens mounting plate 110 through the bearing. For another example, a ball is set at the connection between the lens mounting plate 110 and the lens fixing plate 120, so that the lens fixing plate 120 can be rotatably connected to the lens mounting plate 110 through the ball. The structure that can ensure the rotatable installation of the lens fixing plate 120 and the lens mounting plate 110 belongs to the protection scope of this application and will not be repeated here.

[0028] For further information, please refer to Figure 3The circuit board fixing assembly 20 includes a circuit board mounting seat 210, a circuit board fixing block 220 and a second magnetic member 230. The circuit board mounting seat 210 includes a mounting plane 211 and a limiting retaining wall 212 arranged on the mounting plane 211. The circuit board fixing block 220 is made of metal and has abutment blocks 221 arranged on the surface. The circuit board fixing block 220 and the second magnetic member 230 are respectively arranged on both sides of the limiting retaining wall 212. The circuit board fixing block 220 and the second magnetic member 230 can drive the abutment blocks 221 to move toward the limiting retaining wall 212 through magnetic attraction, so as to clamp the circuit board 40 to be assembled placed on the mounting plane 211. It should be noted that when the circuit board 40 to be assembled is placed on the mounting plane 211, its bottom surface is facing the mounting plane 211. It can be understood that the circuit board fixing block 220 can move relative to the circuit board mounting seat 210 through the second magnetic member 230, and the circuit board 40 to be assembled is installed on the mounting plane 211 of the circuit board mounting seat 210 and abuts against the limiting retaining wall 212. The circuit board fixing block 220 moves toward the circuit board mounting seat 210 under the action of the second magnetic member 230, that is, the abutting block 221 moves toward the limiting retaining wall 212, and then clamps the circuit board 40 to be assembled on the mounting plane 211. Specifically, the side of the circuit board 40 to be assembled is clamped to avoid damaging the electronic devices on the back of the circuit board 40 to be assembled or the photosensitive chip on the front. The use of magnetic clamping can also reduce the difficulty of installing the circuit board 40 to be assembled, and can quickly and conveniently clamp the circuit board 40 to be assembled.

[0029] Please refer again Figure 2 Preferably, the lens fixing assembly 10 further includes a rotating rod 140, and the lens fixing plate 120 is rotatably mounted on the lens mounting plate 110 via the rotating rod 140. Specifically, the rotating rod 140 passes through the lens mounting plate 110 and the lens fixing plate 120 respectively, so that the lens fixing plate 120 is rotatably mounted with the lens mounting plate 110 via the rotating rod 140. The rotating rod 140 in a through connection manner can ensure that the lens fixing plate 120 is stably connected with the lens mounting plate 110, thereby ensuring that the lens 30 to be assembled is stably clamped.

[0030] In one embodiment, a limiting boss 111 and an adsorption metal column 112 are provided on the lens mounting plate 110. The limiting boss 111 is used to install the lens 30 to be assembled, and the adsorption metal column 112 is used to generate magnetic attraction with the first magnetic component 130. Considering that the lens 30 to be assembled is provided with a screw through-hole structure that facilitates the subsequent installation of the camera module on the electronic product, the present design sets a limiting boss 111 on the lens mounting plate 110 to cooperate with the screw through-hole to limit the lens 30 to be assembled and ensure the stability of the installation of the lens 30 to be assembled. Furthermore, by setting the adsorption metal column 112 on the lens mounting plate 110, the adsorption capacity of the first magnetic component 130 is improved, thereby ensuring that the lens fixing plate 120 can clamp the lens 30 to be assembled.

[0031] Please refer again Figure 3 In one embodiment, an avoidance groove 2111 is further opened on the installation plane 211, and the limiting retaining wall 212 is located on one side of the avoidance groove 2111. The avoidance groove 2111 is used to avoid the circuit board 40 to be assembled from colliding with the electronic devices on the installation plane 211, thereby further avoiding the circuit board 40 to be assembled from colliding with the electronic devices during the clamping process, avoiding damage to the electronic devices, and improving the assembly yield of the camera module.

And by arranging the second magnetic member 230 opposite to the movable through hole 213, that is, the second magnetic member 230 is opposite to the circuit board fixing block 220, the magnetic attraction between the second magnetic member 230 and the circuit board fixing block 220 is improved.

[0033] In one embodiment, the circuit board fixing assembly 20 also includes a mounting screw 240 and a screw fixing seat 250, the mounting screw 240 is installed on the circuit board mounting seat 210 through the screw fixing seat 250, and the mounting screw 240 is partially located in the movable through hole 213, and the second magnetic member 230 is installed on the mounting screw 240. The second magnetic member 230 is installed on the circuit board mounting seat 210 through the mounting screw 240 and the screw fixing seat 250, so that different types or sizes of second magnetic members 230 need to be replaced according to the clamping needs of the circuit board 40 to be assembled, thereby improving the applicability of the camera module assembly jig. It should be noted that when a different second magnetic member 230 needs to be replaced, it is only necessary to remove the mounting screw 240 from the screw fixing seat 250 to replace the second magnetic member 230, which is convenient to operate.

[0034] In one embodiment, the mounting screw 240 is connected to the screw fixing seat 250 by threads, and a boss 222 is provided on the surface of the circuit board fixing block 220 facing the mounting screw 240, and the boss 222 is used to abut against the mounting screw 240. The mounting screw 240 and the screw fixing seat 250 are connected by threads, so that the mounting screw 240 is convenient to connect and easy to replace. By providing the boss 222 on the surface of the circuit board fixing block 220 facing the mounting screw 240, it is convenient to determine the specific position of the mounting screw 240 on the screw fixing seat 250, and it is also convenient to control the magnetic attraction between the second magnetic member 230 and the circuit board fixing block 220, and then it is convenient to determine the extrusion force of the circuit board 40 to be assembled by the limiting retaining wall 212 and the abutting block 221, so as to avoid excessive extrusion and clamping force to damage the circuit board 40 to be assembled.

[0035] In one embodiment, the circuit board fixing assembly 20 further includes a fixture base 260, a third magnetic member (not shown in the figure) and a fourth magnetic member 270, the circuit board mounting seat 210 is slidably mounted on the fixture base 260, the third magnetic member is mounted on the circuit board mounting seat 210, the fourth magnetic member 270 is mounted on the fixture base 260, and the third magnetic member and the fourth magnetic member 270 are arranged relative to each other, that is, the third magnetic member drives the circuit board mounting seat 210 to move toward the fourth magnetic member 270, and finally fixes the circuit board mounting seat 210 and the fixture base 260. The circuit board mounting seat 210 is slidably mounted on the fixture base 260, and the positions of the circuit board mounting seat 210 and the fixture base 260 are fixed by the magnetic attraction of the third magnetic member and the fourth magnetic member 270, ensuring the stable connection of the circuit board mounting seat 210. And the circuit board mounting seat 210 is fixed by the sliding installation method, which is also convenient for adjusting the positions of the circuit board 40 to be assembled and the lens 30 to be assembled during the assembly process, thereby improving the assembly accuracy and efficiency of the camera module.

[0037] Please refer to Figure 3 and Figure 4In one embodiment, the circuit board fixing assembly 20 further includes a locking plate 280 and a locking screw 290.
