Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of camera modules, in particular to a structure that is easy to identify the fracture of the FPC board of the module. Background Art
[0002] For a camera module with an FPC board, the structure of its substrate is generally a combination of an FPC board and a PCB board. Since the PCB board is made of hard material and the FPC board is made of soft material. Therefore, in actual tests and use, the FPC board will be bent multiple times, and due to the thickness difference between the FPC board and the PCB board, there are upper and lower steps, which further causes the FPC board to be torn due to multiple bends.
[0003] In the related art, usually glue is added at the step between the FPC board and the PCB board to enhance the elasticity of the FPC board, thereby increasing the number of bending times. However, even so, the two side edges of the FPC board are most likely to be torn because they are subjected to greater stress during the bending process. Since the tear at this position is relatively hidden and is blocked by glue, it is difficult to visually detect the tear, thus increasing the probability of defective products. Summary of the Utility Model
[0004] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a structure that is easy to identify the fracture of the FPC board of the module, which can timely detect the fracture of the FPC board, thereby reducing the probability of defective products.
[0005] The purpose of the utility model is achieved by the following technical solutions:
[0006] The first aspect of the present application provides a structure that is easy to identify the fracture of the FPC board of the module, including: a first plate body; a second plate body, the first plate body is disposed on the second plate body, and a clearance area is provided between the first plate body and the second plate body; a colloid, the colloid is disposed in the clearance area; an identification component, the identification component includes a first bending block and a second bending block, the first bending block is disposed on one side of the second plate body, and the second bending block is disposed on the other side of the second plate body.
[0007] The first bending block and the second bending block are flush with each other.
[0008] A first hollow area is provided between the first bending block and the second plate body.
[0009] A second hollow area is provided between the second bending block and the second plate body.
[0010] The width of the first hollow area is the same as the width of the second hollow area.
[0011] The first bending block has an "L"-shaped cross-sectional structure.
[0012] The second bending block has an "L"-shaped cross-sectional structure.
[0013] The width of the colloid is the same as the width of the second plate body.
[0014] The second plate body is an FPC board.
[0015] It further includes a camera module, and the camera module is arranged on the first plate body.
[0016] Compared with the prior art, the present utility model has at least the following advantages:
[0017] The first bending block and the second bending block are respectively on both sides of the second plate body. By arranging the first bending block and the second bending block, on the one hand, the bending force on the second plate body can be reduced, increasing the number of times it can be bent. On the other hand, when the forces on both sides of the edge of the second plate body are too large, the first bending block and the second bending block will also break, so that the operator can timely identify the damaged second plate body and screen out defective products in time. BRIEF DESCRIPTION OF THE DRAWINGS
[0018] In order to more clearly illustrate the technical solutions of the embodiments of the present utility model, the drawings required to be used in the embodiments will be briefly introduced below.
[0019] Figure 1 It is a schematic structural diagram of a structure for easily identifying the fracture of an FPC board of a module in an embodiment of the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] The embodiments of the present application will be described in more detail below with reference to the drawings. Although the embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present application more thorough and complete, and to fully convey the scope of the present application to those skilled in the art.
[0021] It should be understood that although terms such as "first", "second", and "third" may be used in the present application to describe various information, these information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present application, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, the meaning of "a plurality" is two or more, unless otherwise specifically defined.
[0022] Unless otherwise clearly defined and limited, terms such as "installation", "connection", "linkage", "fixation" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral one; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0023] At present, due to the thickness difference between the FPC board and the PCB board, there are upper and lower steps. Therefore, glue is applied at the steps between the FPC board and the PCB board to enhance the elasticity of the FPC board, thereby increasing the number of bending times. However, despite this, the two side edges of the FPC board are most likely to be torn because they are subjected to greater forces during the bending process. Since the tearing at this position is relatively hidden and is blocked by glue, it is difficult to visually detect the tearing, thus increasing the probability of defective products.
[0024] In view of the above problems, the embodiment of the present application provides a structure for easily identifying the fracture of the module FPC board, which can timely detect the fracture of the FPC board, thereby reducing the probability of defective products.

In order to improve the elasticity of the second board body 200, glue is applied at the clearance area.
