Description

Technical Field

[0001] The utility model relates to the technical field of FPC panel splicing, and more specifically, to an FPC panel splicing structure. Background Art

[0002] With the rapid development of modern electronic technology, electronic devices are increasingly evolving towards the direction of being thinner, lighter, smaller, and more multifunctional. Under this background, flexible printed circuit boards (FPCs), as a kind of electronic material with excellent flexibility and bendability, are widely used in various electronic devices, especially those with extremely strict space requirements, such as smart phones, tablet computers, wearable devices, etc.; during the production process of FPCs, copper foil, as its core component, its processing accuracy and utilization rate directly affect the overall performance and production cost of FPCs. However, traditional FPC cutting methods often seem inadequate when dealing with FPCs with irregular shapes.

[0003] Traditional cutting lines are usually single straight-line cutting lines, which directly cut along the upper and lower edges of the FPC after layout. This method is highly efficient when dealing with FPCs with regular shapes, but once faced with FPCs with irregular shapes, its drawbacks are immediately revealed. Since the waste area near the edge is relatively large after the layout of FPCs with irregular shapes, and the straight-line cutting line cannot be flexibly adjusted according to the specific shape of the FPC monomer, the waste area is further increased. This not only wastes valuable material resources, but also reduces the number of FPC monomers in the layout, thereby increasing the production cost and reducing the competitiveness of the product. Therefore, we have made improvements in this regard and proposed an FPC panel splicing structure. Summary of the Utility Model

[0004] The technical problem to be solved by the embodiments of the present utility model is that traditional cutting lines usually adopt single straight-line cutting lines. Since the waste area near the edge is relatively large after the layout of FPCs with irregular shapes, and the straight-line cutting line cannot be flexibly adjusted according to the specific shape of the FPC monomer, the waste area increases.

[0005] To solve the above technical problem, the present utility model adopts the following technical solutions:

[0006] An FPC panel structure includes: an FPC panel main body, on which several single-piece FPC main bodies are provided. The several single-piece FPC main bodies are divided into multiple rows, and a bending cutting line located on the FPC panel main body is provided between adjacent rows of single-piece FPC main bodies. The bending cutting line is bent. In this application, according to the waste area formed by the shape of the single-piece FPC main body, the bending cutting line is designed. The bending cutting line is bent and adapted to the shape of the single-piece FPC main body, which can reduce the area of the waste area. Thus, the typesetting quantity of the single-piece FPC main body can be increased under the same typesetting area, the utilization rate of the FPC panel main body material is improved, the production cost is reduced, and the competitiveness of the product is enhanced.

[0007] As an improved mode of the utility model, several positioning holes are provided on the FPC panel main body, and the positioning holes are used for positioning the FPC panel main body.

[0008] As an improved mode of the utility model, a support fixture is provided on the bottom surface of the FPC panel main body, and the support fixture is used for supporting and limiting the FPC panel main body.

[0009] As an improved mode of the utility model, the support fixture is composed of several support fixing mechanisms, and the several support fixing mechanisms are detachably connected.

[0010] As an improved mode of the utility model, the support fixing mechanism includes a support table, a positioning rod is fixedly connected to the top of the support table, and the outer surface of the positioning rod is inserted into the positioning hole.

[0011] As an improved mode of the utility model, a connection plug board is fixedly connected to one side of the support table, a slot is opened on the other side of the support table, and the outer surface of the connection plug board is inserted into the adjacent slot.

[0012] As an improved mode of the utility model, a hook and a buckle are fixedly installed on the side surface of the support table, and the buckle is buckled with the adjacent hook.

[0013] As an improved mode of the utility model, a groove is opened on the side of the top of the support table, and the shape and position of the groove are adapted to the shape and position of the bending cutting line.

[0014] As an improved mode of the utility model, a first vacuum groove is opened in the support table, several first vacuum adsorption holes are opened on the top of the support table, the first vacuum adsorption holes are communicated with the first vacuum groove, and a first connecting pipe communicated with the first vacuum groove is fixedly connected to one side of the support table.

[0015] As an improved form of the present utility model, a second vacuum groove located below the first vacuum groove is further opened in the support table. A plurality of second vacuum adsorption holes are opened at the top of the support table. The second vacuum adsorption holes are communicated with the second vacuum groove. One side of the [description missing in the original] is fixedly connected with a second connecting pipe communicated with the first vacuum groove.

[0016] Compared with the prior art, the embodiments of the present utility model mainly have the following beneficial effects:

[0017] To solve the problem in the prior art that the traditional cutting line usually adopts a single straight-line cutting line. Since the waste area near the edge is relatively large after the FPC with a special-shaped structure is typeset, and the straight-line cutting line cannot be flexibly adjusted according to the specific shape of the single FPC monomer, resulting in an increase in the waste area. According to the waste area formed by the outer shape of a single FPC main body, the present application designs a bent cutting line. The bent cutting line is bent and adapted to the outer shape of the single FPC main body, which can reduce the waste area. Thus, the typesetting quantity of the single FPC main body can be increased under the same typesetting area, improving the utilization rate of the main material of the FPC layout, reducing the production cost, and enhancing the competitiveness of the product.

Detailed implementation mode

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this utility model belongs; the terms used in the specification of this application are only for the purpose of describing specific embodiments, and are not intended to limit this utility model. The mention of "embodiment" in this article means that a specific feature, structure or characteristic described in connection with the embodiment can be included in at least one embodiment of this utility model. The appearance of this phrase at various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0027] As recorded in the background art, traditional cutting lines are usually single straight-line cutting lines, which are directly cut along the upper and lower edges of the FPC after typesetting. This method is efficient when dealing with regular-shaped FPCs, but once faced with FPCs with special-shaped structures, its disadvantages are fully revealed. Since the waste area near the edge is large after the FPC with special-shaped structure is typeset, and the straight cutting line cannot be flexibly adjusted according to the specific shape of the FPC monomer, resulting in a further increase in the waste area. This not only wastes precious material resources, but also reduces the typesetting quantity of the FPC monomer, thereby increasing production costs and reducing the competitiveness of products.

[0028] To solve this technical problem, this utility model provides an FPC panel structure.

[0029] Specifically, please refer to Figure 1 - Figure 2 , the FPC panel structure specifically includes:

[0030] An FPC panel main body 1 is provided with a plurality of single-piece FPC main bodies 3. The plurality of single-piece FPC main bodies 3 are divided into multiple rows, and a bent cutting line 2 located on the FPC panel main body 1 is provided between adjacent rows of single-piece FPC main bodies 3. The bent cutting line 2 is bent.

[0031] The FPC panel structure provided by the present utility model designs a bending cutting line 2 according to the waste material area formed by the shape of a single FPC main body 3. The bending cutting line 2 is bent and adapted to the shape of the single FPC main body 3, which can reduce the area of the waste material area. Thus, the typesetting quantity of the single FPC main body 3 can be increased under the same typesetting area, improving the utilization rate of the material of the FPC panel main body 1, reducing the production cost, and enhancing the competitiveness of the product.

[0032] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings.

[0033] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments can be combined with each other.

[0034] It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0035] Embodiment 1 of the FPC panel structure of the present utility model

[0036] Please refer to Figure 1 - Figure 2 , the FPC panel structure of the present utility model includes: an FPC panel main body 1, on which several single FPC main bodies 3 are arranged. The several single FPC main bodies 3 are divided into multiple rows, and a bending cutting line 2 located on the FPC panel main body 1 is arranged between adjacent two rows of single FPC main bodies 3. The bending cutting line 2 is bent. The present application designs the bending cutting line 2 according to the waste material area formed by the shape of the single FPC main body 3. The bending cutting line 2 is bent and adapted to the shape of the single FPC main body 3, which can reduce the area of the waste material area. Thus, the typesetting quantity of the single FPC main body 3 can be increased under the same typesetting area, improving the utilization rate of the material of the FPC panel main body 1, reducing the production cost, and enhancing the competitiveness of the product.

[0037] Furthermore, as Figure 1 - Figure 2 shown, several positioning holes 4 are arranged on the FPC panel main body 1. The positioning holes 4 are used for positioning the FPC panel main body 1 to reduce the situation that the FPC panel main body 1 moves during cutting.

[0038] Referring to Figure 3 , Figure 3 shows the comparison between cutting with a straight cutting line and cutting with the bending cutting line 2. The shaded part marked at A is the material saved by the present application.

[0039] The bending cutting line 2 is designed according to the outer shape of the single-piece FPC main body 3 and is bent to adapt to the outer shape of the single-piece FPC main body 3. This design enables minimizing the waste generated during cutting to increase the typesetting quantity of the single-piece FPC main body 3 under the same typesetting area, achieving the purpose of improving the material utilization rate.

[0040] Embodiment 2 of the FPC layout structure of the present utility model

[0041] Furthermore, for the FPC layout structure of the present utility model, as Figure 4 - Figure 6 shown, a support fixture is provided on the bottom surface of the FPC layout main body 1. The support fixture is used for the support and positioning of the FPC layout main body 1. By supporting and positioning the FPC layout main body 1 through the support fixture, the stability of the FPC layout main body 1 during the cutting process can be improved, movement can be reduced, and the cutting accuracy can be enhanced.

[0042] Furthermore, as Figure 5 shown, the support fixture is composed of several support fixing mechanisms 5. The several support fixing mechanisms 5 are detachably connected, so that the number of support fixing mechanisms 5 can be adjusted according to the length of the FPC layout main body 1, improving the applicable range of this application.

[0043] Furthermore, as Figure 4 - Figure 6 shown, the support fixing mechanism 5 includes a support table 501. A positioning rod 511 is fixedly connected to the top of the support table 501. The outer surface of the positioning rod 511 is inserted into the positioning hole 4. By inserting the positioning rod 511 into the positioning hole 4, the FPC layout main body 1 can be fixed, reducing the situation where the position of the FPC layout main body 1 moves.

[0044] Furthermore, as Figure 5 - Figure 6 shown, a connecting plug board 504 is fixedly connected to one side of the support table 501, and a slot 505 is provided on the other side of the support table 501. The outer surface of the connecting plug board 504 is inserted into the adjacent slot 505. By inserting the connecting plug board 504 into the adjacent slot 505, the adjacent two support fixing mechanisms 5 can be supported, making the two support fixing mechanisms 5 more stable.

[0045] Furthermore, as Figure 5 and Figure 6As shown, a hook 502 and a buckle 503 are fixedly installed on the side of the support platform 501. The buckle 503 is engaged with the adjacent hook 502. Through the mutual cooperation of the hook 502 and the buckle 503, the adjacent two support fixing mechanisms 5 can be fixed. The support fixing mechanisms 5 are connected by the insertion of a connecting plug board 504 and a slot 505, and are fixed in cooperation with the engagement of the hook 502 and the buckle 503. This connection method is simple and fast, and the number of support fixing mechanisms 5 can be increased or decreased according to the length of the FPC panel main body 1 to meet the requirements of different lengths.

[0046] Further, as Figure 5 - Figure 6 shown, a groove 506 is formed on the edge side of the top of the support platform 501. The shape and position of the groove 506 are adapted to the shape and position of the bending and cutting line 2. The setting of the groove 506 can provide corresponding space for the cutting blade during the cutting process, reduce interference with the support platform 501, and improve the smoothness and accuracy of cutting.

[0047] Embodiment III of the FPC panel structure of the present utility model

[0048] Further, as Figure 5 shown, a first vacuum groove is formed in the support platform 501. A plurality of first vacuum adsorption holes 507 are formed on the top of the support platform 501. The first vacuum adsorption holes 507 are communicated with the first vacuum groove. One side of the support platform 501 is fixedly connected with a first connecting pipe 508 communicated with the first vacuum groove. A vacuum device is used to evacuate through the first connecting pipe 508, the first vacuum groove and the first vacuum adsorption holes 507, so that the single FPC main body 3 can be fixed on the support fixing mechanism 5.

[0049] Further, as Figure 5 shown, a second vacuum groove is further formed in the support platform 501 below the first vacuum groove. The second vacuum groove is not communicated with the first vacuum groove, so as not to cause interference. A plurality of second vacuum adsorption holes 509 are formed on the top of the support platform 501. The second vacuum adsorption holes 509 are communicated with the second vacuum groove. One side is fixedly connected with a second connecting pipe 510 communicated with the first vacuum groove. A vacuum device is used to evacuate through the second connecting pipe 510, the second vacuum groove and the second vacuum adsorption holes 509, so that the FPC panel main body 1 can be fixed on the support fixing mechanism 5, thereby realizing the fixation of the position of the FPC panel main body 1. Moreover, the position of the second vacuum adsorption holes 509 is close to the groove 506, so as to facilitate the fixation of the part of the FPC panel main body 1 beside the bending and cutting line 2 during the cutting process, prevent movement during cutting, and further improve the cutting accuracy and efficiency.

[0050] In use, select the corresponding number of support and fixing mechanisms 5 according to the length of the FPC layout main body 1. After inserting the connecting plug board 504 into the adjacent slot 505, buckle the buckle 503 with the adjacent hook 502. Then connect the first connecting pipe 508 and the second connecting pipe 510 to the vacuum device. Place the FPC layout main body 1 on the top of the support table 501 and make the positioning rod 511 insert into the positioning hole 4. Then cut along the trajectory of the bending cutting line 2 on the FPC layout main body 1.
