It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.
[0033] In addition, if terms such as "first", "second", etc. are only used for distinguishing descriptions, they cannot be understood as indicating or implying relative importance.
[0034] It should be noted that, without conflict, the features in the embodiments of the present utility model can be combined with each other.
[0035] Please also combine Figures 1 to 2 to describe the folding fixture for the pressure-sensitive touch product provided by the present utility model. The folding fixture for the pressure-sensitive touch product is used in a false press.
[0036] The folding fixture for the pressure-sensitive touch product includes a base 1 and a folding rod 4. The base 1 is provided with a first positioning member 21 and a second positioning member 22. Both the first positioning member 21 and the second positioning member 22 are used to position the non-folding end 102. The folding rod 4 is rotatably connected to the base 1. The folding rod 4 is provided with a third positioning member 31. The third positioning member 31 is used to position the folding end 101. By rotating the folding rod 4, the folding rod 4 drives the folding end 101 to be folded and attached to the non-folding end 102.
[0037] It can be understood that the base 1 of the folding fixture for the pressure-sensitive touch product is provided with a first positioning member 21 and a second positioning member 22. Both the first positioning member 21 and the second positioning member 22 are used to position the non-folding end 102, so that the non-folding end 102 can be fixed. The folding rod 4 is rotatably connected to the base 1. The folding rod 4 is provided with a third positioning member 31. The third positioning member 31 is used to position the folding end 101, thereby fixing the folding end 101. By rotating the folding rod 4, the folding rod 4 drives the folding end 101 to be folded and attached to the non-folding end 102, so that the folding external force during the folding process is consistent, avoiding poor accuracy when the product is folded individually, and thus improving the production quality and efficiency of the product.
[0038] In addition, by setting the first positioning member 21 and the second positioning member 22, the non-folding end 102 can be fixed on the base 1, avoiding the deviation influence caused by the alignment deviation during the fitting operation.
[0039] It should be added that the folding jig for the pressure-sensitive touch product is placed on a heating platform at 120 ± 10 °C. It can only be folded after the folding jig for the pressure-sensitive touch product has heated up to the initial adhesion temperature of the adhesive, which is 100 ± 10 °C. If the temperature is too low, the adhesion of the adhesive is insufficient, and it will rebound and separate after folding. If the temperature is too high, it will affect safe operation.
[0040] In this embodiment, two folding rods 4 are provided and symmetrically arranged on the base 1. Since the FPC module 100 has two folding ends 101 and the two folding ends 101 need to be folded and attached to the non-folding end 102, two folding rods 4 are provided to fold the two folding ends 101 simultaneously.
[0041] Specifically, the folding rod 4 is kept horizontal, and the entire length of the folding rod 4 can ensure the unity of the folding direction during the folding process, avoiding the deviation of the force direction at the folding end 101 caused by the deviation of the operator's gesture during manual operation, resulting in misalignment during attachment. When the folding rod 4 folds, the entire FPC module 100 is folded at one time, making the operation smoother and more efficient, and greatly improving the folding efficiency.
[0042] Furthermore, the first positioning member 21 and the second positioning member 22 are respectively arranged in a staggered manner with the third positioning member 31. Since positioning holes are provided in both the folding end 101 and the non-folding end 102, in order to prevent interference between the first positioning member 21 and the second positioning member 22 and the third positioning member 31 after the folding rod 4 folds, the first positioning member 21 and the second positioning member 22 are respectively arranged in a staggered manner with the third positioning member 31. In addition, after the folding rod 4 folds, the third positioning member 31 can extend into the positioning holes without the first positioning member 21 and the second positioning member 22, and the first positioning member 21 and the second positioning member 22 can extend into the positioning holes without the third positioning member 31, thus ensuring the accuracy after folding.
[0043] In one embodiment, as Figures 1 to 3 shown, the folding jig for the pressure-sensitive touch product further includes a fixing member 3, a support platform 2 and a cover plate 5. The support platform 2 is connected to the base 1. The support platform 2 is provided with a first positioning member 21 and a second positioning member 22. The fixing member 3 is installed on the base 1. The folding rod 4 is rotatably connected to the base 1. The cover plate 5 covers the fixing member 3, the folding rod 4, the folding end 101 and the non-folding end 102. An external force is applied to the cover plate 5 to make the folding end 101 coincide with the non-folding end 102. After the folded folding rod 4 is reset, the cover plate 5 is covered on the folding rod 4, the folding end 101 and the non-folding end 102, and an external force is applied to the cover plate 5 so that the cover plate 5 can overlap the folding end 101 and the non-folding end 102 together to complete the folding production.
[0044] In this embodiment, the cover plate 5 is provided with an avoidance groove 51 for avoiding the fixing member 3. This enables the force applied to the cover plate 5 to act on the folding end 101 and the non-folding end 102.
[0045] Further, the cover plate 5 is further provided with an avoidance hole 52 for avoiding the first positioning member 21, the second positioning member 22 and the third positioning member 31. The first positioning member 21, the second positioning member 22 and the third positioning member 31 can respectively penetrate through the avoidance hole 52, so that the cover plate 5 can be covered on the folded end 101 and the non-folded end 102.
[0046] In an embodiment, as Figure 1 shown, the folding jig for the pressure-sensitive touch product further includes a rotating shaft 6, and the folding rod 4 is rotatably connected to the fixing member 3 through the rotating shaft 6. By providing the rotating shaft 6, the folding rod 4 can move relative to the fixing member 3.
[0047] In this embodiment, the rotating shaft 6 is eccentrically connected to the folding rod 4 so that the folding rod 4 can be turned and pressed on the support table 2. The rotating shaft 6 is eccentrically connected to the folding rod 4, so that the folding rod 4 can rotate 180 degrees and cover on the support table 2, so that the folded end 101 can be folded.
[0048] Further, the folding jig for the pressure-sensitive touch product further includes a fastener 7. The fastener 7 penetrates through the fixing member 3 and is connected to the base 1. Specifically, the fastener 7 can be a bolt. The fastener 7 penetrates through the fixing member 3 and is threadedly connected to the base 1, so that the fixing member 3 can be stably connected to the base 1.
[0049] After adding the folding rod 4 in the present utility model, the folding action is simplified. The entire FPC product only needs to flip the folding rod 4 and rotate 180° to cover on the jig of the base 1. The folding efficiency is increased from the original 30 pieces / h to 100 pieces / h, greatly improving the production efficiency. At the same time, the folding and laminating overlap accuracy is increased from the original ±0.2 mm to ±0.1 mm, fully meeting the customer's quality requirements, and has been mass-produced.
[0050] The present utility model further provides a false press. The false press includes a pressing module and the folding jig for the pressure-sensitive touch product in any of the above embodiments. The pressing module can press the folded end 101 and the non-folded end 102 attached to the folding jig of the pressure-sensitive touch product at a preset pressure and a preset temperature.
[0051] Specifically, the FPC module 100 after folding and laminating and the folding jig for the pressure-sensitive touch product are placed in the false press together, and are pressed for a period of time under the action of a certain pressure and temperature to ensure that the adhesive on the folded end 101 can be fully adhered to the non-folded end 102 after folding.
[0052] It can be understood that the false press of the present utility model uses the folding fixture of the above-mentioned pressure-sensitive touch product, so that the base 1 of the folding fixture of the pressure-sensitive touch product is provided with a first positioning member 21 and a second positioning member 22. Both the first positioning member 21 and the second positioning member 22 are used to position the non-folding end 102, so that the non-folding end 102 can be fixed. The folding rod 4 is rotatably connected to the base 1, and the folding rod 4 is provided with a third positioning member 31. The third positioning member 31 is used to position the folding end 101, so as to fix the folding end 101. Rotate the folding rod 4, and the folding rod 4 drives the folding end 101 to be folded and attached to the non-folding end 102, so that the folding external force during the folding process is consistent, avoiding poor accuracy when the product is folded individually, thereby improving the production quality and efficiency of the product.
[0053] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.
[0054] The above-disclosed are only the preferred embodiments of the present utility model. Of course, the scope of the rights of the present utility model cannot be limited thereby. Therefore, equivalent changes made according to the claims of the present utility model still fall within the scope covered by the present utility model.
