[0068] A method for preparing integrated mobile phone accessories comprises the following steps:

[0069] Specifically, the main material wires of all components of mobile phone accessories can be cut into the required width size using a circular knife, and then the following steps can be performed.

[0070] Step 1: After positioning, die-cut the adhesive protective film, and then superimpose the non-adhesive part obtained by die-cutting on the adhesive protective film;

[0071] Positioning can be performed through a positioning film, and after positioning, it is convenient to determine the position of the adhesive protective film, and to facilitate die-cutting of the adhesive protective film; during die-cutting, the internal shape of the adhesive protective film is positioned by die-cutting, the handle of the adhesive protective film is positioned by a dismantling knife, and the handle position of the subsequent imitation film, and the left and right side roads are used to die-cut the outer shape of the adhesive protective film, which is convenient for alignment; specifically, a Charge Coupled Device automatic alignment system (i.e., CCD) for alignment can also be provided for alignment.

[0072] The anti-wear print layer, battery buffer layer, decorative adhesive and fingerprint layer can be die-cut on the adhesive protective film first, leaving die-cutting marks to facilitate the subsequent positioning of the anti-wear print layer, battery buffer layer, decorative adhesive and fingerprint layer.

[0073] According to the partial die-cutting marks of the appearance of the above-mentioned anti-wear print layer, battery buffer layer, decorative back glue and fingerprint layer, the glue-free parts corresponding to the top anti-wear print layer, bottom anti-wear print layer, left anti-wear print layer and right anti-wear print layer are positioned and placed, so as to facilitate the subsequent die-cutting and superimposing setting of the top anti-wear print layer, bottom anti-wear print layer, left anti-wear print layer and right anti-wear print layer.

Specifically, the lining portion corresponds to the through hole on the battery buffer layer, which can assist in the die-cutting of the battery buffer layer. The lining portion can pad the battery buffer layer to facilitate the discharge of waste inside the battery buffer layer.

[0076] Step 3: superimposing the fingerprint layer obtained by die-cutting on the adhesive protective film, and superimposing the decorative adhesive obtained by die-cutting on the adhesive protective film;

If the thickness is relatively large or small, it will affect the subsequent die-cutting of the adhesive surface 13, making it difficult for the adhesive surface 13 to adhere to the adhesive surface of the anti-wear printing layer, the battery buffer layer 4, the decorative adhesive 7 and the fingerprint layer 8, making the anti-wear printing layer, the battery buffer layer 4, the decorative adhesive 7 and the fingerprint layer 8 easily displaced, affecting the product yield.

[0123] Specifically, the padding layers of the top anti-wear print layer 2 and the bottom anti-wear print layer 3 only serve to raise the height. When used subsequently, the padding layers need to be connected to the adhesive protective film 11 and torn off for use; and the function of the first padding layer is to stick to the adhesive protective film 11, and the function of the second padding layer is to increase the height, which can be set according to the actual needs of the customer; the function of the third padding layer is to separate from the Mylar layer to prevent the Mylar layer from being torn off when the padding layer is torn off.

[0129] Comparative Example 1 is a method for preparing integrated mobile phone accessories, which differs from Example 1 only in that there is no step of superimposing the die-cut lining part in step 2. Die-cutting easily discharges the product along with the waste during the waste discharge process.

[0130] Comparative Example 2 is a method for preparing integrated mobile phone accessories. The only difference from Example 1 is that in step 2, when die-cutting the top anti-wear printing layer and the bottom anti-wear printing layer, the top anti-wear printing layer and the bottom anti-wear printing layer are not cut apart by a cutting line. Due to the problem of the stress point, the product will be stuck by the waste and discharged.

[0131] Comparative Example 3 is a method for preparing an integrated mobile phone accessory component, which is different from Example 1 only in that the fingerprint layer is die-cut first and then the lining layer is die-cut.

[0132] Comparative Example 4 is a method for preparing integrated mobile phone accessories. The only difference from Example 1 is that the top anti-wear printing layer and the bottom anti-wear printing layer do not contain a cushioning layer. The anti-wear printing layer and the bottom anti-wear printing layer are height-restricted relative to the surrounding adhesive. When the customer reassembles, the adhesive layer cannot be activated and cannot be bonded due to the height difference.

[0133] Comparative Example 5 is a method for preparing an integrated mobile phone accessory component, which is different from Example 1 only in that no positioning holes are provided on the decorative rubber surface.

[0134] Comparative Example 6, a method for preparing integrated mobile phone accessories, differs from Example 1 only in that there is no step of stacking a mobile phone base film on the adhesive surface. After die-cutting, the mobile phone base film can be sorted by automated equipment for convenient packaging, while also preventing secondary defects caused by adhesion between products.

[0135] Among them, in Example 1 and Comparative Examples 1 to 6, people are set up to check each step of the mobile phone auxiliary parts in the preparation process. First, the size and appearance are detected by CCD photography, and then the defective products are simply discharged according to the appearance through manual sampling to prevent the mixing of good and defective products and affect the subsequent preparation steps; at the same time, when the mobile phone auxiliary parts in the preparation process are glued, they are manually processed. Finally, the inspectors and quality control personnel will carefully inspect the appearance again, and then organize the packaging and put it into a special blister box.

[0136] Among them, the mobile phone accessories prepared in Example 1 are as follows Fig. 9 shown.

[0137] The mobile phone accessories prepared in Example 1 and Comparative Examples 1 to 6 were subjected to the following tests, and the test result data table obtained is shown in the following table.

[0138] Yield test: two-dimensional dimension measurement and manual appearance inspection.

[0139] Preparation cycle test: the time required for the entire preparation process of a product (mobile phone accessories).

[0140] Table 1 Test results of Example 1 and Comparative Examples 1 to 6

[0141] Yield rate (%) Preparation cycle (h) Can it be produced continuously? Embodiment 1 92 24 yes Comparative Example 1 72 18 no Comparative Example 2 80 20 no Comparative Example 3 81 24 no Comparative Example 4 83 20 no Comparative Example 5 85 24 no Comparative Example 6 89 20 no

[0142] According to Table 1, the preparation method of Example 1 can continuously produce mobile phone accessories, the preparation cycle of a mobile phone accessory is short, and the yield rate of the prepared mobile phone accessories is high, and less manpower is required to check the yield rate.

[0143] In Comparative Examples 1 to 6, at least two or more people need to be set up at each step node to manually check the yield rate, and perform auxiliary operations such as waste discharge and anti-sticking. Among them, in Comparative Examples 1, 2 and 6, due to the lack of some steps, the preparation cycle is shortened, but at the same time the yield rate drops significantly, and manual positioning, waste discharge, anti-sticking and other operations are required in the middle, making it difficult to carry out continuous production; in Comparative Example 3, since the fingerprint layer is small, the fingerprint layer is die-cut first, which may lead to inaccurate positioning of the fingerprint layer, and then affect the positioning and die-cutting of the subsequent lining layer and battery buffer layer, resulting in a decrease in the yield rate; in Comparative Example 4, there is a lack of a cushioning layer setting that can make the anti-wear printing layer basically level with the large backing glue, making it difficult to accurately position some components of the mobile phone accessories, resulting in a decrease in the client assembly yield rate and the failure of the product fitting due to the inability to maintain pressure to activate the product double-sided adhesive; in Comparative Example 5, there is a lack of positioning holes for positioning, which makes the positioning operation more complicated and the accuracy is reduced, reducing the yield rate.

[0144] In summary, the present application provides a mobile phone accessory and its integrated preparation method and integrated die-cutting device. After positioning, the integrated preparation method of mobile phone accessories can integrally place the non-glue part obtained by die-cutting, the top anti-wear print layer and the bottom anti-wear print layer, the left anti-wear print layer and the right anti-wear print layer, the fingerprint layer, the decorative glue, the battery buffer layer, the imitation film of the large glue, the glue surface of the large glue and the mobile phone accessory bottom film in sequence on the glue protective film of the large glue, so as to prepare the mobile phone accessories; the whole preparation step is simple, and the mobile phone accessories can be assembled in an integrated manner, and the preparation efficiency is high.
