Description

Technical Field

[0001] The utility model relates to the technical field of jigs, in particular to a drilling positioning jig. Background Art

[0002] In the manufacturing process of electronic components, especially in the production process of flexible circuit boards (FPCs), the accuracy of drilling is crucial to the accuracy of subsequent component assembly. Traditionally, the drilling positioning of FPC substrates is achieved by manually measuring the distance between the direction limit hole (a small hole pre-set on the FPC substrate, used as a positioning reference point) and the edge of the substrate. The accuracy of this positioning method depends on the operator's experience and the accuracy of the operation. The positioning accuracy is limited, usually with a deviation of ±1mm, and the positioning efficiency is low. If the size or quality of the substrate edge does not meet the standard, it will further lead to a large deviation in the drilling, which will affect the subsequent processing of the product.

[0003] Therefore, there is an urgent need for a drilling positioning fixture to ensure accurate and rapid positioning of the FPC substrate and improve the accuracy and efficiency of drilling. Utility Model Content

[0008] The limiting assembly includes a fixed limiting pin installed in the fixed limiting hole and a movable limiting pin installed in the movable limiting hole.

[0009] Optionally, the limiting hole group includes a first limiting hole group and a second limiting hole group, and the first limiting hole group and the second limiting hole group both include a plurality of movable limiting holes distributed at a first interval;

It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0027] The technical solution of the present utility model will be further described below in conjunction with the accompanying drawings and through specific embodiments.

[0028] Referring to Figures 1 to 4 , the drilling positioning fixture disclosed in this embodiment includes: a fixture base plate 10 configured with an installation position and a limiting component 20 for fixing the substrate 01; the installation position is used to place the substrate 01, and the installation position includes multiple installation edges, and the multiple installation edges enclose to form the installation position;

[0029] The fixture base plate 10 is fixed on the workbench surface of the drilling machine. Along one of the installation edges on the fixture base plate 10, several groups of limiting hole groups are provided. Each limiting hole group includes a plurality of movable limiting holes 12 distributed along the direction perpendicular to one of the installation edges. Along the remaining installation edges on the fixture base plate 10, a plurality of fixed limiting holes 11 are respectively provided;

[0030] The limiting component 20 includes fixed limiting pins 21 installed in the fixed limiting holes 11 and movable limiting pins 22 installed in the movable limiting holes 12.

[0031] During use, the substrate 01 is loaded into the installation position from the side where the movable limiting holes 12 are distributed, and then the substrate 01 is fixed on the installation position of the fixture base plate 10 through the fixed limiting pins 21. Finally, according to the length of the substrate 01, the movable limiting pins 22 are installed in the appropriate movable limiting holes 12, so as to fix the remaining one edge of the substrate 01. This design ensures that the substrate 01 can be accurately and quickly fixed in the installation position. Compared with the traditional method of positioning by manually measuring the distance between the direction limiting holes and the edge of the substrate 01 board, it does not depend on the experience of the operator and the accuracy of the operation, has higher positioning accuracy, and at the same time has higher positioning efficiency, thereby improving the accuracy and efficiency of drilling; the plurality of movable limiting holes 12 are distributed along the direction perpendicular to one of the installation edges, so that it can be applicable to substrates 01 of different lengths, increasing the applicable range and flexibility of the fixture and improving the production efficiency.

[0032] In this embodiment, the substrate 01 is square. Therefore, the installation position on the fixture base plate 10 includes four installation edges. Along the extension directions of three sides of the substrate 01 on the fixture base plate 10, a plurality of fixed limiting holes 11 are respectively provided, and the plurality of fixed limiting holes 11 are arranged in a C shape. During use, the substrate 01 is loaded from the opening formed by the fixed limiting pins 21, and then the three sides of the substrate 01 are fixed on the fixture base plate 10 through the fixed limiting pins 21. Finally, according to the length of the substrate 01, the movable limiting pins 22 are installed in the appropriate movable limiting holes 12, so as to fix the other edge of the substrate 01 on the fixture base plate 10 as well. This design ensures that the substrate 01 can be accurately and quickly fixed in the installation position. The drilling positioning fixture disclosed in this application is also applicable to substrates 01 of other shapes, such as substrates 01 in the shape of a triangle.

[0033] Reference Figure 3 and Figure 4 The limiting hole group includes a first limiting hole group and a second limiting hole group, and the first limiting hole group and the second limiting hole group both include a plurality of movable limiting holes 12 distributed at a first spacing 121; wherein, along a direction perpendicular to one of the mounting edges, the second limiting hole group and the first limiting hole group leave a second spacing 122, and the second spacing 122 is smaller than the first spacing 121. This design provides fine adjustment of the movable limiting pins 22 by subdividing the spacing, thereby increasing the positioning accuracy of the substrate 01.

[0034] Furthermore, there are multiple groups of second limiting hole groups, and each group of second limiting hole groups is correspondingly provided with a different second spacing 122; along the direction of one of the mounting edges, the second spacing 122 corresponding to the next group of second limiting hole groups is greater than the second spacing 122 corresponding to the previous group of second limiting hole groups. The number of second limiting hole groups is diverse, and the spacings are differentiated. The diversified spacing design can accurately match substrates of specific sizes, thereby ensuring high precision of the drilling position and reducing errors in the processing process.

[0035] Furthermore, the difference between the second spacings 122 corresponding to two adjacent groups of second limiting holes is equal. This uniform spacing difference design ensures the positioning consistency of substrates 01 of different lengths, and helps to achieve uniform accuracy in the entire processing area.

[0036] Furthermore, a gap is provided between the fixed limiting pin 21 and the substrate 01, and the width of the gap is 0.1-0.3 mm, preferably 0.2 mm. Proper gaps are provided between the fixed limiting pin 21 and the substrate 01 to prevent the substrate 01 from being stuck too tightly and causing difficulty in removal or wrinkling of the substrate 01 when being removed.

[0037] Furthermore, at least one mounting hole 13 is provided at each of the four corners of the fixture base plate 10 , and two mounting holes 13 are provided at one of the corners of the fixture base plate 10 .

[0038] The fixture base plate 10 is fixed on the work surface of the drilling machine through the fixing pins and the mounting holes 13 , and the basic coordinates of the drilling holes are established according to the positions of the mounting holes 13 to ensure that the drilling holes on the substrate 01 can be accurately positioned.

[0039] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
