Description

Technical Field

[0001] The present application relates to the technical field of flexible circuit boards, and in particular to an FPC dispensing method and an FPC. Background Art

[0002] As their use becomes increasingly widespread, FPCs (Flexible Printed Circuits) are not only becoming smaller, shorter, thinner, and more flexible, but are also becoming larger and longer. Since conventional flexible circuit boards are relatively small, the sizes that can be processed by their corresponding dispensing equipment are also limited.

[0003] When dealing with long flexible circuit boards, there are two traditional dispensing methods: segmented processing or using longer dispensing equipment. Segmented processing not only increases processing time and costs, but also requires customizing the equipment, which also increases costs. Summary of the Invention

It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0031] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0033] References to "one embodiment," "some embodiments," or "an embodiment" in this specification mean that a particular feature, structure, or characteristic described in conjunction with that embodiment is included in one or more embodiments of the present invention. Thus, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," and "in other embodiments" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. Furthermore, in one or more embodiments, particular features, structures, or characteristics may be combined in any suitable manner.

[0034] In order to illustrate the technical solution of the present application, the following description is given with reference to specific drawings and embodiments.

[0035] Please refer to Figure 1 and Figure 2 The embodiment of the first aspect of the present application provides an FPC dispensing method, comprising:

[0036] S100 : providing an FPC 10 , wherein the FPC 10 has a plurality of glue-dispensing sections 12 and a non-glue-dispensing section 11 disposed between two adjacent glue-dispensing sections 12 .

[0037] Specifically, the FPC 10 is relatively long, and the non-glue-dispensing section 11 does not need to be glued, but the plurality of glue-dispensing sections 12 all need to be glued.

[0038] It can be understood that a non-glue section 11 is provided between all adjacent two glue dispensing sections 12, for example, multiple non-glue sections 11 can be provided; or, a non-glue section 11 is provided between only some adjacent two glue dispensing sections 12, for example, a non-glue section 11 is provided between only two adjacent glue dispensing sections 12.

[0039] S200 : providing a fixture 20 , the fixture 20 including a carrying plate 21 , the carrying plate 21 having a carrying surface 211 , and a receiving hole 212 being provided on the carrying surface 211 .

[0040] Specifically, the carrying surface 211 on the carrying plate 21 is used to place the FPC 10. The overall length of the fixture 20 is smaller than the overall length of the FPC 10. Therefore, the entire FPC 10, that is, the non-glue dispensing section 11 and multiple glue dispensing sections 12 cannot be placed on the carrying surface 211 for glue dispensing at the same time.

[0041] It can be understood that when multiple non-dispensing sections 11 are provided, multiple accommodating holes 212 can be provided at intervals.

[0042] S300 : placing a plurality of glue-dispensing segments 12 on the carrying surface 211 , and bending the non-glue-dispensing segment 11 and placing it into the receiving hole 212 .

[0043] Specifically, multiple dispensing segments 12 are supported by the supporting surface 211. After the non-dispensing segment 11 is bent and placed in the accommodating hole 212, the distance between the multiple dispensing segments 12 becomes shorter, so they can be placed on the supporting surface 211 at the same time for dispensing, thereby eliminating the need to replace a longer-sized jig 20 or dispensing equipment.

[0044] It is understandable that the entire non-glue-dispensing section 11 may be bent and placed into the accommodating hole 212 , or a portion of the non-glue-dispensing section 11 may be bent and placed into the accommodating hole 212 .

[0045] It can be understood that the non-glue-dispensing section 11 has a certain degree of flexibility and can recover normally after bending.

[0046] S400: performing glue dispensing on a plurality of glue dispensing sections 12 .

[0047] Specifically, the dispensing equipment can be used to automatically dispense glue according to the designed dispensing route and dispensing amount, without the need to perform segmented processing on multiple dispensing sections 12, thereby saving processing time and improving processing accuracy.

[0048] It can be understood that the fixture 20 and FPC10 can be placed on the track of the dispensing equipment according to the direction, the positioning points can be collected and the dispensing route and dispensing amount can be designed, and then the dispensing equipment can be used to automatically dispense glue according to the designed dispensing route and dispensing amount.

[0049] The FPC dispensing method provided in the embodiment of the present application is to first place the multiple dispensing segments 12 of the FPC 10 on the bearing surface 211 of the jig 20, and then bend the non-dispensing segment 11 and place it in the accommodating hole 212 on the bearing surface 211, and then dispense the multiple dispensing segments 12. Therefore, the dispensing of the multiple dispensing segments 12 of the FPC 10 can be completed at one time without replacing the longer dispensing equipment, without the need for segmented processing, and the processing time is short, the production efficiency is high, the precision is high, and the cost is low.

[0050] Optionally, after dispensing glue on the plurality of dispensing sections 12, the thickness and position of the glue dots are checked to see if they meet the quality requirements. In this way, the quality of subsequent dispensing can be guaranteed.

[0051] The effective processing length of conventional dispensing equipment is 590mm, while the FPC dispensing method provided in the embodiment of the present application can perform one-time processing and dispensing of new energy flexible circuit boards with a product length exceeding 1000mm or even exceeding 1500mm, without the need for segmented dispensing (i.e., performing multiple processing on FPC10 in the same process).

[0052] Please refer to Figure 2 and Figure 4 In some embodiments, the jig 20 further includes a carrying box 22 disposed on one side of the carrying plate 21, a receiving hole 212 passes through the carrying plate 21, and the carrying box 22 is connected to an end of the receiving hole 212 away from the carrying surface 211; when a plurality of dispensing segments 12 are placed on the carrying surface 211, the non-dispensing segment 11 is bent and placed into the receiving hole 212 and the carrying box 22.

[0053] By adopting the above solution, it is possible to avoid the non-glue-dispensing section 11 placed in the accommodating hole 212 and the carrying box 22 from being suspended in the air, which may cause scratches and wrinkles after being pulled.

[0054] Optionally, the carrying box 22 and the carrying plate 21 are detachably connected, such as by a snap connection or a magnetic connection. In this way, when the non-glue-dispensing segment 11 needs to be removed from the accommodating hole 212 and the carrying box 22, the carrying box 22 only needs to be removed from the carrying plate 21 first, and then the non-glue-dispensing segment 11 can be removed from the accommodating hole 212. This operation is simple and convenient for removing the non-glue-dispensing segment 11 from the accommodating hole 212 and the carrying box 22.

[0055] Please refer to Figure 2 In some embodiments, in order to facilitate the placement of the non-glue dispensing segment 11 into the accommodating hole 212 and prevent the hole wall of the accommodating hole 212 from scratching the non-glue dispensing segment 11, the width of the accommodating hole 212 is greater than the width of the non-glue dispensing segment 11 in the direction perpendicular to the arrangement of the multiple glue dispensing segments 12.

[0056] In some embodiments, the side edge of the accommodating hole 212 near the supporting surface 211 is rounded to prevent the side edge of the accommodating hole 212 near the supporting surface 211 from scratching the non-dispensing section 11.

[0057] Please refer to Figure 2 、 Figure 4 and Figure 5 In some embodiments, a positioning portion 121 is provided on the dispensing segment 12, and a matching portion 213 is provided on the carrying surface 211; when multiple dispensing segments 12 are placed on the carrying surface 211, the positioning portion 121 is matched and connected with the matching portion 213.

[0058] By adopting the above solution, the multiple glue dispensing segments 12 can be accurately positioned when they are placed on the carrying surface 211, so as to perform a precise glue dispensing operation subsequently.

[0059] Alternatively, the positioning portion 121 is configured as a positioning hole and the mating portion 213 is configured with a positioning post; or the positioning portion 121 is configured as a positioning post and the mating portion 213 is configured with a positioning hole. This can simplify the structures of the positioning portion 121 and the mating portion 213 and facilitate processing.

[0060] In this embodiment, the positioning portion 121 is configured as a positioning hole, and the matching portion 213 is provided with a positioning post.

[0061] Optionally, the side of the positioning post away from the end of the supporting plate 21 is rounded, so that the positioning hole can be conveniently sleeved on the positioning post.

[0062] Please refer to Figure 2 、 Figure 4 and Figure 5 The bearing surface 211 is further provided with a limiting groove 214 for accommodating the dispensing segment 12. It is understood that the limiting groove 214 is adapted to the shape of the plurality of dispensing segments 12, or the length and width of the limiting groove 214 are both greater than the length and width of the plurality of dispensing segments 12.

[0063] After placing multiple glue dispensing segments 12 on the supporting surface 211 and before dispensing glue on the multiple glue dispensing segments 12, the FPC dispensing method also includes: covering the FPC 10 with a cover plate 30, with the side of the cover plate 30 close to the supporting plate 21 being in contact with the supporting surface 211, and the side of the glue dispensing segment 12 away from the supporting plate 21 being in contact with the side of the cover plate 30 close to the supporting plate 21.

[0064] By adopting the above solution, the dispensing section 12 can be made smoother before dispensing, thereby facilitating subsequent precise dispensing, and also preventing the cover plate 30 from crushing the plurality of dispensing sections 12 .

[0065] It is understood that the length and width of the cover plate 30 should ensure that the side of the dispensing section 12 away from the carrier plate 21 can be completely in contact with the side of the cover plate 30 close to the carrier plate 21 .

[0066] Optionally, the cover plate 30 and the carrier plate 21 are connected by magnetic attraction, for example, a magnet is provided on the cover plate 30 and the carrier plate 21 is provided with a magnetic metal material. In this way, the connection process and the separation process of the cover plate 30 and the carrier plate 21 can be made more convenient.

[0067] Please continue to refer to Figure 2 、 Figure 4 and Figure 5In some embodiments, the dispensing section 12 has a dispensing position 122 ; the cover plate 30 is provided with an avoidance hole 31 ; after the cover plate 30 is used to cover the FPC 10 , the avoidance hole 31 exposes the dispensing position 122 .

[0068] By adopting the above solution, the glue dispensing section 12 can be made smoother, and the glue dispensing at the glue dispensing position 122 on the glue dispensing section 12 is not affected.

[0069] It can be understood that there is a welding device that needs to be glued at the glue dispensing position 122.

[0070] In this embodiment, a positioning hole is also provided at the glue dispensing position 122 .

[0071] Optionally, the cover plate 30 is provided with a through hole 32; when the cover plate 30 is placed on the FPC 10, the through hole 32 is positioned over the positioning post. This allows for more precise positioning of the cover plate 30, the FPC 10, and the carrier plate 21, ensuring that the cover plate 30 flattens the multiple dispensing sections 12 and that the avoidance holes 31 fully expose the dispensing positions 122.

[0072] In some embodiments, after the glue dispensing is performed on the plurality of glue dispensing segments 12 , the plurality of glue dispensing segments 12 are subjected to a curing process, such as UV curing or high temperature curing. The curing method is selected according to the properties of the glue used.

[0073] By adopting the above solution, the dispensed glue can be quickly solidified.

[0074] Optionally, after the plurality of glue-dispensing sections 12 are cured, the cover plate 30 is first removed from the FPC 10 , and then the bent non-glue-dispensing section 11 is removed from the accommodating hole 212 and the carrying box 22 .

[0075] It can be understood that when removing the curved non-glue section 11 from the accommodating hole 212 and the carrying box 22, the glue section 12 should be separated from the carrying surface 211 first, and then the curved non-glue section 11 should be removed from the accommodating hole 212 and the carrying box 22. This process should avoid tearing the FPC 10.

[0076] Optionally, after the bent non-glue-dispensing section 11 is taken out from the accommodating hole 212 and the carrying box 22 , the FPC 10 is subjected to product inspection and subsequent functional testing.

[0077] An embodiment of the second aspect of the present application provides an FPC 10, which is manufactured by the FPC dispensing method of the first aspect.

[0078] The FPC 10 provided in the embodiment of the present application first places the multiple glue-dispensing sections 12 of the FPC 10 on the bearing surface 211 of the jig 20, and then bends the non-glue-dispensing section 11 and places it into the receiving hole 212 on the bearing surface 211, and then glue-dispensing is performed on the multiple glue-dispensing sections 12. Therefore, the glue-dispensing work of the multiple glue-dispensing sections 12 of the FPC 10 can be completed at one time without replacing a longer-sized glue-dispensing device, without the need for segmented processing, resulting in a shorter processing time, higher production efficiency, higher precision, and lower cost.

[0079] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. 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 various embodiments of the present application, and should all be included in the scope of protection of the present application.
