Description

Technical Field

[0001] The utility model relates to the technical field of camera module packaging, and in particular to a packaging cover plate, a packaging tray and a packaging component. Background Art

[0002] The mobile phone camera is mainly composed of a lens, a sensor, a capacitor, a printed circuit board assembly, a lens housing, a reinforcement plate, and a filter. The structure of the printed circuit board assembly includes a camera module, a flexible circuit board, and a connector. The camera module and the connector are respectively connected to the two ends of the flexible circuit board. During the assembly process, the camera module needs to be reinforced at the reinforcing plate reinforcement unit packaging station. During packaging, the camera module and the structure connected to it are placed on the packaging tray, and the camera module is inserted into the acupuncture point structure. Since there is a risk of the camera module being thrown out when the packaging tray is moved, it is necessary to cover the packaging cover at the top to prevent the camera module from being thrown out of the acupuncture point structure when moving.

[0003] As the size of mobile phones increases, the printed circuit board assembly becomes thicker and longer. The previous single-surface package cover design, which is only hollowed out at the camera module, will squeeze the flexible circuit board and connector. In addition, the package cover cannot be well positioned on the package tray, causing the entire printed circuit board assembly to move between the package cover and the package tray when the package cover is added. The camera module on the tray is lifted from the acupuncture point structure, causing the product to often cause the machine height measurement alarm due to the product lifting when moving to the dispensing / bonding station, affecting normal operation.

[0042] In the implementation of the assembly of a mobile phone camera, it is necessary to frequently move the printed circuit board assembly to complete the assembly process in different workstations. The structure of the printed circuit board assembly includes a camera module, a flexible circuit board and a connector. The camera module and the connector are respectively connected to both ends of the flexible circuit board. During assembly, the camera module is mainly processed. The encapsulation cover plate 100 and the encapsulation tray 200 form an encapsulation assembly for placing and moving the printed circuit board assembly.

[0043] Refer to Figure 1, the encapsulation cover plate 100 of the embodiment of the present utility model includes a cover plate main body 110 and at least one positioning structure 120. The cover plate main body 110 is used to press the printed circuit board assembly to prevent it from being thrown out of the encapsulation tray 200 during movement, causing accidents. The positioning structure 120 cooperates with the printed circuit board assembly to stably position the camera module in the acupoint structure 220 of the encapsulation tray 200.

[0044] In some embodiments, positioning holes are also formed on the cover plate main body 110 for positioning between the encapsulation cover plate 100 and the encapsulation tray 200. For example, positioning holes are formed at positions near the four corners of the cover plate main body 110, and the positioning holes cooperate with the positioning protrusions or positioning posts at corresponding positions on the encapsulation tray 200 to achieve positioning and prevent the encapsulation cover plate 100 from sliding on the encapsulation tray 200, causing the printed circuit board assembly to be driven and thrown out of the encapsulation tray 200.

[0045] Figure 2 For Figure 1 The part of structure A in Figure 2 , the positioning structure 120 includes an avoidance hole 121 and an anti-warping hole 122. The avoidance hole 121 is used to avoid the camera module to facilitate processing the camera module at different workstations. The anti-warping hole 122 is used to avoid the connector to reduce the contact area between the encapsulation cover plate 100 and the printed circuit board assembly, prevent excessive extrusion of the printed circuit board assembly, and enable the camera module to be stably embedded in the encapsulation tray 200 without warping. According to the actual situation, the relative positional relationship between the avoidance hole 121 and the anti-warping hole 122 can be adjusted to adapt to printed circuit board assemblies of different specifications. For example, change the distance between the avoidance hole 121 and the anti-warping hole 122 to adapt to printed circuit board assemblies with different flexible circuit board lengths and prevent them from warping out of the acupoint structure during product movement, affecting normal operation.

[0046] In some embodiments, the avoidance hole 121 is provided with a profiling contour corresponding to the camera module, and the anti-warping hole 122 is provided with a profiling contour corresponding to the connector to better avoid the camera module and the connector, reduce the occlusion and extrusion of the printed circuit board assembly by the encapsulation cover plate 100. According to the actual situation, the shapes of the avoidance hole 121 and the anti-warping hole 122 in the horizontal cross-section include rounded rectangles. At this time, the areas avoided by the avoidance hole 121 and the anti-warping hole 122 are larger than the areas of the camera module and the connector in the horizontal cross-section, which can prevent excessive extrusion of the printed circuit board assembly and further enable the camera module to be stably embedded in the encapsulation tray 200.

[0047] In some embodiments, the number of the positioning structures 120 is multiple and they are evenly spaced on the cover plate main body 110 to process and move multiple printed circuit board assemblies simultaneously during assembly.

[0048] Reference Figure 3 The packaging tray 200 of the embodiment of the utility model comprises a tray body 210, at least one acupuncture point structure 220 and at least one magnet 230. The packaging tray 200 is used to provide support for the printed circuit board assembly and drive the printed circuit board assembly to move between different workstations.

[0049] In some embodiments, the tray body 210 is also provided with positioning protrusions or positioning columns for cooperating with positioning holes provided on the packaging cover plate 100 for positioning, so as to prevent the packaging cover plate 100 from sliding on the packaging tray 200, causing the printed circuit board assembly to be driven and thrown out of the packaging tray 200.

[0050] Reference Figure 4 At least one acupuncture point structure 220 is provided on the tray body 210 for placing the printed circuit board assembly. The acupuncture point structure 220 includes a module slot 221 and an extension slot 222. The module slot 221 is used to place the camera module; the extension slot 222 is used to place the extended flexible circuit board and the connector. The extension slot 222 has a bending portion formed by a curved edge shape, and the shape of the bending portion is designed to be a contoured shape according to the actual specifications of the printed circuit board assembly. For example, the extension slot 222 is designed to be an S-shaped extension on the horizontal interface to better accommodate the flexible circuit board, avoid problems such as unevenness on the packaging tray 200 that affect the stability of the placement of the printed circuit board assembly, and cause the camera module to tilt and affect the operation.

[0051] According to actual conditions, the shapes and relative positions of the module slot 221 and the extension slot 222 can be adjusted to adapt to printed circuit board assemblies of different specifications. Figures 5 - 6 , increase the distance between the bent portion of the extension groove 222 and the module groove 221 to accommodate printed circuit board assemblies with different flexible circuit board bending and placement methods; reduce the curvature of the chamfered corners of the extension groove 222 to accommodate printed circuit board assemblies with flexible circuit boards of different specifications, so as to avoid them from warping up from the acupuncture point structure when the product is moved and affecting normal operation.

[0052] At least one magnet 230 is also mounted on the tray body 210. The package cover plate 100 is a ferromagnetic cover plate, and the magnet 230 can adsorb the package cover plate 100, so that the package cover plate 100 can be well positioned and more effectively protect the printed circuit board assembly, preventing it from being thrown out of the package tray 200 or moving between the package cover plate 100 and the package tray 200, causing the camera module to tilt and affect normal operation.

[0053] In some embodiments, the number of acupoint structures 220 is multiple, which is the same as the number of positioning structures 120 on the encapsulation cover plate 100. The multiple acupoint structures 220 are evenly spaced on the tray body 210 and correspond to the positions of the positioning structures 120. According to the actual situation, the arrangement of the positioning structures 120 and the acupoint structures 220 changes according to the specifications and requirements of the product.

[0054] In some embodiments, the number of magnets 230 is multiple to achieve a better adsorption effect and prevent the printed circuit board assembly from being thrown out of the encapsulation tray 200 during movement. The multiple magnets 230 are evenly spaced on the tray body 210, and the number and positions of the magnets 230 can be associated with the number and positions of the acupoint structures 220. For example, each column of magnets 230 is arranged on the upper and lower sides of the corresponding column of acupoint structures 220, so that the printed circuit board assembly placed in the encapsulation tray 200 can be stabilized on both the upper and lower sides, preventing it from moving between the encapsulation cover plate 100 and the encapsulation tray 200.

[0055] Figure 7 is a top view of an encapsulation component according to an embodiment of the present application, Figure 8 For Figure 7 the structure of part B in is locally enlarged.

[0056] For the encapsulation component composed of the encapsulation cover plate 100 and the encapsulation tray 200, refer to Figures 7 - 8 , the position of the module slot 221 corresponds to the position of the avoidance hole 121, and the position of the tail of the extension slot 222 corresponds to the position of the anti-warping hole 122. After the printed circuit board assembly is placed, the camera module is embedded in the module slot 221 and is avoided through the avoidance hole 121; part of the flexible circuit board and the connector are installed in the extension slot 222, and the connector is avoided through the anti-warping hole 122; the remaining part of the flexible circuit board is positioned by the downward pressure of the cover plate body 110. On the basis of providing effective positioning and avoidance of the camera module, further avoidance of the connector is achieved through the anti-warping hole 122, reducing the extrusion of the encapsulation cover plate 100 on the printed circuit board assembly, enabling the camera module to be stably embedded in the encapsulation tray 200 and preventing it from warping during movement, ensuring normal operation.

[0057] Since both the camera module and the connector are connected to the flexible circuit board, at this time, the printed circuit board assembly is inverted in the encapsulation tray 200, and its top surface is a long strip-shaped flexible circuit board, and the camera module is located below the flexible circuit board. Refer to Figure 9, for each column of module slots 221, the tray body 210 is recessed to form a through strip-shaped slot. On this basis, each module slot 221 is recessed to form an independent accommodation space. According to the actual situation, the inside of the module slot 221 is provided with a bump clamping structure and an avoidance structure that cooperate with the camera module. The extension slot 222 is recessed on the basis of the tray body 210, leaving a space for accommodating the flexible circuit board. At the same time, the height of the extension slot 222 is higher than the height of the strip-shaped slot where the module slot 221 is located, and a part of it extends into the strip-shaped slot. That is to say, the top surface of the tray body 210, the extension slot 222, the top surface of the strip-shaped slot, and the top surface of the module slot 221 are sequentially reduced in height. The module slot 221 communicates with the extension slot 222. After the printed circuit board assembly is placed, the downwardly protruding camera module is snapped into the module slot 221, and the extended flexible circuit board and the connector are placed in the extension slot 222. And for the flexible circuit board that does not contact the camera module and is located in the strip-shaped slot, its lower surface can be supported by the part that protrudes from the surface of the strip-shaped slot after the extension slot 222 extends into the strip-shaped slot, so that the flexible circuit board can be better accommodated by the encapsulation tray 200, avoiding uneven placement of the flexible circuit board, reducing the extrusion of the printed circuit board assembly after the encapsulation cover plate 100 is covered, and avoiding the warping of the camera module and affecting the operation.

[0058] In the embodiment of the present application, the encapsulation assembly includes an encapsulation cover plate and an encapsulation tray. The encapsulation cover plate includes a cover plate body and at least one positioning structure. The positioning structure includes an avoidance hole and an anti-warping hole; the encapsulation tray includes a tray body, at least one acupoint structure, and at least one magnet. By providing an avoidance hole and an anti-warping hole on the encapsulation cover plate, the camera module and the connector are respectively avoided, reducing the extrusion of the encapsulation cover plate on the printed circuit board assembly. The magnet can adsorb the encapsulation cover plate, position the encapsulation cover plate, and more effectively position the printed circuit board assembly to prevent it from moving, so that the camera module can be stably embedded in the encapsulation tray, avoiding it from warping out of the acupoint structure during product movement and ensuring normal operation.

[0059] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various modifications and changes can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
