AI Technical Summary
在现有的技术中，会使用一个定位柱穿入FPC部件和NFC部件的定位孔的方式实现对位，并且为了避免0.3mm的加工公差问题导致无法对位，定位柱的直径会比FPC部件和NFC部件的定位孔的直径小0.3mm，而在FPC部件和NFC部件上会均设置直径相同的定位孔，这会造成在对位时导致对位精度不高、对位作业时效慢、损坏物料等问题的发生
[0010]采用上述方案，本实用新型的有益效果在于：采用模组FPC的定位孔和NFC中定位孔尺寸不同的方式，通过具有两段不同直径的定位柱体来对应模组FPC和NFC中的定位孔，不仅方便拿取，也可以通过在对位完成后通过NFC和模组FPC由于孔径尺寸差在定位孔位处漏出的尺寸判断对位效果，可以提高FPC和NFC组装对位精度，在对位组装完成后方便直观检查对位效果。

Abstract
Description
Technical Field
[0001] This utility model relates to the field of display module technology, and in particular to a structure that facilitates the alignment of FPC modules. Background Technology
[0002] In display modules, especially in wearable devices, it is sometimes necessary to bend and fold two FPC components together, or to stack FPC components with other materials (such as NFC components). In these cases, high alignment accuracy is required. Current technology uses a positioning post inserted into the positioning holes of both the FPC and NFC components for alignment. To avoid misalignment due to a 0.3mm machining tolerance, the diameter of the positioning post is 0.3mm smaller than the diameter of the positioning holes in the FPC and NFC components. However, both the FPC and NFC components have positioning holes of the same diameter. This leads to problems such as low alignment accuracy, slow alignment time, and material damage during alignment.
[0003] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content
[0004] The purpose of this invention is to overcome at least some of the shortcomings of the prior art and to provide a structure that facilitates the alignment of module FPCs.
[0005] The technical solution of this utility model is as follows: This utility model provides a structure for facilitating the alignment of a module FPC, used for the alignment of a module FPC, including: a first component with a first positioning hole, a second component with a second positioning hole, and a positioning post. The first component and the second component are positioned by a positioning post penetrating the corresponding first positioning hole and second positioning hole. The first component includes at least two first positioning holes with a diameter of 'a' mm, and the second component includes at least two second positioning holes with a diameter of 'b' mm. The positioning post includes a connected first positioning post body and a second positioning post body. The first positioning post body and the second positioning post body are both cylinders and coaxially arranged. The first positioning post body is used to pass through the first positioning hole during positioning, and the second positioning post body is used to pass through the second positioning hole during positioning. The diameter of the first positioning post body is a-0.2 mm, and the diameter of the second positioning post body is b-0.6 mm.
[0006] Furthermore, the first component is a module FPC, and the second component is an NFC, wherein the NFC is attached to the module FPC and electrically connected to the module FPC.
[0007] Furthermore, the height of the first positioning post is 0.5 mm, and the height of the second positioning post is 0.25 mm.
[0008] Furthermore, the edge distance between the two first positioning holes is greater than or equal to 5 mm.
[0009] Furthermore, the diameter of the first positioning hole is 1 mm, and the diameter of the second positioning hole is 1.6 mm.
[0010] The beneficial effects of this utility model by adopting the above solution are as follows: by using different sizes of positioning holes in the module FPC and the NFC, positioning columns with two different diameters are used to correspond to the positioning holes in the module FPC and the NFC. This not only makes it convenient to pick up, but also allows for the judgment of the alignment effect by the size of the hole difference between the NFC and the module FPC at the positioning hole position after alignment. This can improve the alignment accuracy of FPC and NFC assembly, and facilitate intuitive inspection of the alignment effect after alignment assembly. Attached Figure Description

[0012] Figure 2 This is a schematic diagram of the structure of the first and second positioning holes of the module FPC after it is aligned with the NFC in one embodiment of the present invention.
[0013] Figure 3 This is a schematic diagram of the positioning column according to an embodiment of the present invention. Detailed Implementation
[0014] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0015] Please refer to the following: Figures 1 to 3In this embodiment, the present invention provides a structure for facilitating the alignment of a module FPC, comprising: a first component 1 having a first positioning hole 11, a second component 2 having a second positioning hole 21, and a positioning post 3. The first component 1 and the second component 2 are positioned by a positioning post 3 penetrating the corresponding first positioning hole 11 and second positioning hole 21. The first component 1 includes at least two first positioning holes 11 with a diameter of 1 mm, and the second component 2 includes at least two second positioning holes 21 with a diameter of 1.6 mm. The positioning post 3 includes a connecting first positioning post 31 and a second positioning post 31. 32. Both the first positioning post 31 and the second positioning post 32 are cylindrical and coaxially arranged. The first positioning post 31 is used to pass through the first positioning hole 11 during positioning, and the second positioning post 32 is used to pass through the second positioning hole 21 during positioning. The diameter of the first positioning post 31 is 0.8 mm, which is 0.2 mm smaller in diameter and 0.1 mm smaller in radius on one side compared to the 1 mm diameter of the first positioning hole 11, thus improving positioning accuracy. The diameter of the second positioning post 32 is 1 mm, used to align with the 1.6 mm second positioning hole, and its radius on one side is 0.3 mm smaller, which can cover the positioning inaccuracy caused by the 0.3 mm machining tolerance. When using the positioning post 3 for alignment, the first positioning post 31 is inserted into the first positioning hole 11, and the second positioning post 32 is inserted into the second positioning hole 21. The alignment effect can be adjusted by the size exposed at the first positioning hole 11 and the second positioning hole 21 due to the difference in hole diameter, thus achieving more precise alignment.
[0016] Furthermore, the first component 1 is a module FPC, and the second component 2 is an NFC, wherein the NFC is attached to the module FPC and electrically connected to the module FPC.
[0017] Furthermore, the height of the first positioning post 31 is 0.5 mm, and the height of the second positioning post 32 is 0.25 mm, to avoid excessive length affecting alignment.
[0018] Furthermore, the edge distance between the two first positioning holes 11 is greater than or equal to 5 mm to avoid the problem of inaccurate positioning caused by the distance between the two positioning holes being too close.
[0019] In summary, the beneficial effects of this solution are as follows: by using positioning holes of different sizes in the module FPC and the NFC, and by using positioning posts with two different diameters to correspond to the positioning holes in the module FPC and the NFC, it is not only convenient to handle, but also allows for the judgment of the alignment effect by the size of the hole difference between the NFC and the module FPC at the positioning hole position after alignment. This can improve the alignment accuracy of FPC and NFC assembly, and facilitate intuitive inspection of the alignment effect after alignment assembly.
[0020] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
