[0053] Example 1

[0054] See also Figure 1 Embodiment 1 of the present invention discloses a method for printing a mobile phone rear cover, the method comprising:

[0055] S1: defining the relative position relationship between the hollow baffle plate and the mobile phone back cover so that the hollow portion of the hollow baffle plate overlaps with the to-be-printed area of ​​the mobile phone back cover;

[0056] Specifically, a hollow baffle is attached to the back shell of the mobile phone so that the hollow part of the hollow baffle overlaps with the to-be-printed area of ​​the back shell of the mobile phone, and the non-hollow part is used to cover and protect the area on the mobile phone that does not need to be printed, thereby protecting other areas of the mobile phone. The material of the hollow baffle is not limited, and it can be a sticky plastic film, or a hollow baffle with a fixed structure can be selected to achieve the effect of not falling off and protecting the non-printing area. The shape of the hollow part of the hollow baffle is determined according to the to-be-printed area. In this embodiment, the hollow baffle uses a sticky plastic film, which can be attached to the back shell of the mobile phone. Figure 2As shown in the figure, the rectangular shaded part is the area to be printed, and the non-shaded part is the non-printing area. The shape of the hollow baffle is rectangular so as to coincide with the area to be printed on the back shell of the mobile phone. The area to be printed is not the size of the actual printing pattern, but an area convenient for printing is set according to the shape and size of the pattern to be printed, such as Figure 3 As shown, the sticky hollow baffle is attached to the back shell of the mobile phone so that the hollow part of the hollow baffle overlaps with the to-be-printed area of ​​the back shell of the mobile phone.

[0057] S2: Surface tension modification treatment of the area to be printed;

[0058] Specifically, because the back shell of the finished mobile phone has been treated with anti-fingerprint, anti-oil, and dust-proof treatments, these treatments will affect the printing effect. If the pattern is directly printed on the to-be-printed area of ​​the back shell of the mobile phone without surface modification treatment, the printing effect is not good. Therefore, it is necessary to change the surface tension of the back shell of the mobile phone to achieve a better printing effect. After the hollow baffle is attached to the back shell of the mobile phone, the surface tension modification treatment of the to-be-printed area on the back shell of the mobile phone is started. The purpose is to change the physical properties of the area to increase the adhesion of the area and achieve a better printing effect. The treatment method for changing the surface tension of the back shell of the mobile phone includes: The method for performing surface tension modification treatment on the material includes: plasma treatment, generating plasma through high-voltage discharge, and the active particles in the plasma react with the surface of the back shell of the mobile phone to change its surface tension; the flame treatment surface modification method uses the high temperature generated by the flame to change the chemical composition of the material surface, thereby increasing its surface tension.

[0059] In one embodiment, the step S2: performing surface tension modification treatment on the area to be printed includes:

[0060] S21: Acquire plasma processing parameters, wherein the plasma processing parameters at least include: plasma processing time and power;

[0061] S22: performing plasma treatment on the area to be printed according to the plasma treatment parameters.

[0062] Specifically, plasma treatment is to generate plasma through high-voltage discharge. The active particles in the plasma react with the surface of the mobile phone back shell to change its surface tension. The parameters of plasma treatment need to be determined according to the characteristics of the mobile phone back shell, such as the material of the mobile phone back shell, the surface treatment condition and other factors. The parameters include plasma treatment time and discharge power. These data can be obtained through experiments based on actual conditions. Which set of parameters can better improve the surface tension of the mobile phone back shell? According to the parameters obtained from the experiment, the hollow part of the hollow baffle, that is, the area to be printed, is subjected to plasma treatment. After the plasma treatment is completed, wait for the mobile phone back shell to cool to room temperature, that is, the surface tension modification treatment of the mobile phone back shell is completed. Plasma treatment can effectively improve the surface adhesion of the area to be printed on the mobile phone back shell, ensuring that the ink in the subsequent coating and UV printing process can better adhere to the mobile phone back shell.

[0063] In one embodiment, the step S2: performing surface tension modification treatment on the area to be printed includes:

[0064] S23: Acquire flame treatment parameters, wherein the flame treatment parameters at least include: flame treatment time and flame temperature;

[0065] S24: performing flame treatment on the area to be printed according to the flame treatment parameters.

[0066] Specifically, the method of flame treatment surface modification is to use the high temperature generated by the flame to change the chemical composition of the material surface, thereby increasing its surface tension. The parameters of the flame treatment are determined according to the characteristics of the mobile phone back shell, such as material, surface treatment status, etc. The main influencing parameters are the temperature of the flame and the time of the flame treatment. These data can be obtained through experiments based on actual conditions. Which set of parameters can better improve the surface tension of the mobile phone back shell? According to the parameters obtained from the experiment, the hollow part of the hollow baffle, that is, the area to be printed, is flame treated. The flame treatment equipment is controlled by manual or automated equipment to move evenly along the area to be printed to ensure that the printing area can receive the flame treatment. After the flame treatment is completed, wait for the mobile phone back shell to cool to room temperature. The flame treatment can effectively improve the surface adhesion of the area to be printed on the mobile phone back shell. By improving the surface adhesion, it can be ensured that the ink in the subsequent coating and UV printing process can better adhere to the back shell of the mobile phone.

[0067] S3: Setting a coating on the area to be printed;

[0068] Specifically, after completing the treatment of changing the surface tension of the area to be printed, in order to further improve the adhesion of the ink on the back shell of the mobile phone so that the ink can be stably printed on the back shell of the mobile phone, it is necessary to apply a coating to the treated area to be printed. The coating can serve as a base layer for UV ink, which helps to improve the quality of the printed pattern, making it clearer, more vivid and durable. The coating can increase the durability of the printed pattern, so that the pattern maintains a good appearance under different environmental conditions such as high and low temperatures, boiling, etc., and the coating can quickly absorb the ink, reduce the diffusion and penetration time of the ink on the surface of the printing medium, thereby accelerating the drying speed and preventing the ink from forming uneven patterns on the surface of the printing medium. The coating also helps the ink to be evenly distributed on the surface of the printing medium, avoiding spots or stripes and improving the printing quality. The method of applying the coating includes: silk screen printing, hand rubbing the coating or machine printing.

[0069] In one embodiment, see Figure 4 , the step S3: providing a coating on the area to be printed comprises:

[0070] S31: Get the set coating thickness;

[0071] S32: Setting a screen plate on the area to be printed;

[0072] S33: applying the coating to the area to be printed through a screen plate according to the coating thickness;

[0073] S34: Drying the coating on the area to be printed.

[0074] Specifically, according to the physical properties of the back shell of the mobile phone, the coating thickness is set, and the coating thickness can be obtained by testing, for example, coatings of different thicknesses are applied on a back shell of the mobile phone to be tested, and which thickness can provide sufficient ink adhesion without affecting the printing quality of the subsequent steps. Set a screen plate that matches the area to be printed. The mesh size on the screen plate should be selected according to the coating material and the required coating thickness. Place the screen plate above the area to be printed on the back shell of the mobile phone, ensure that the screen plate is in close contact with the back shell of the mobile phone, without air bubbles or gaps, use a clamp or other fixing device to keep the screen plate stable to avoid movement during the coating process, use a scraper to evenly pass the coating material through the mesh of the screen plate and apply it to the area to be printed. According to the required coating thickness, repeat this process until the required coating thickness is reached. The coating thickness can be measured manually or by machine vision, which is not limited here. After the coating is completed, wait for natural air drying or use hot air to accelerate the drying process. Using a screen plate to apply the coating can ensure that the coating is evenly distributed over the entire area to be printed, further making the adhesion of the back shell of the mobile phone uniform and improving the quality of subsequent printing.

[0075] S4: Control the printer to print ink on the coating layer of the area to be printed.

[0076] Specifically, the coating of the area to be printed is completed, the ink adhesion of the surface of the back shell of the mobile phone is improved, and then the ink is printed on the coating of the area to be printed to form a printed pattern. The ink includes: white ink, color ink, varnish and other inks. In this process, in order to improve the accuracy of the ink at the position to be printed, positioning points can be printed on the hollow baffle plate. According to the positioning points, the hollow area of ​​the hollow baffle plate is positioned using a visual positioning system to determine the position of the hollow area of ​​the hollow baffle plate to ensure the accuracy of the position during the printing process.

[0077] In one embodiment, see Figure 5 , the step S4: controlling the printer to print ink on the coating of the area to be printed comprises:

[0078] S41: Acquire position information of a positioning point on the hollow baffle plate;

[0079] S42: acquiring the position of the to-be-printed area according to the position information of the positioning point;

[0080] S43: Printing the print image onto the coating layer of the area to be printed according to the position of the area to be printed.

[0081] Specifically, a positioning point for positioning is printed on the hollow baffle in advance. The positioning point is also called a Mark point. The form of the positioning point is not limited. The form of the positioning point includes a commonly used circular point, a cross, a color block or other easily identifiable marks, such as Figure 6 As shown, two cross-shaped Mark points are printed on the hollow baffle. When the hollow baffle is fixed on the back shell of the mobile phone, the hollow position of the hollow baffle coincides with the area to be printed. When the image of the positioning point of the hollow baffle is obtained, the physical coordinates of the positioning point are calculated, so as to further calculate the position information of the area to be printed. Specifically, it can be to use a visual recognition device, such as a CCD camera, to capture the image of the Mark point on the hollow baffle, perform coordinate conversion on the image, calculate the position information of the Mark point, and calculate the exact position of the area to be printed on the back shell of the mobile phone based on the position information of the Mark point and the size of the hollow baffle. The calculated position information of the area to be printed is used to adjust the nozzle position of the UV printer to ensure that the print head is aligned with the area to be printed, and print the pattern to be printed to the area to be printed. This method ensures that the printed image falls accurately on the area to be printed, improves printing accuracy, uses visual recognition equipment for automatic positioning, reduces manual errors, and improves printing efficiency.

[0082] In one embodiment, see Figure 7 The step S43: printing the print image on the area to be printed according to the position of the area to be printed comprises:

[0083] S431: Acquire print data of a print image;

[0084] S432: printing one or more of white ink, color ink, and varnish on the coating of the to-be-printed area in sequence according to the printing data and the position of the to-be-printed area;

[0085] S433: UV curing is performed on the area to be printed.

[0086] Specifically, an image file to be printed is obtained, which contains the pattern and color information to be printed, and the image file is converted into a format compatible with the printer, such as PDF, TIFF or a special printing instruction format. If the image requirements are high in the scenario, the image file can be preprocessed, such as adjusting the resolution, color correction and other image processing operations. According to the position of the area to be printed obtained above, the nozzle position of the printer is adjusted according to the position of the area to be printed, and it is ensured that the print head is aligned with the area to be printed. If a white background is required to enhance the contrast of the color pattern, first print a layer of white ink on the coating of the area to be printed, and then print color ink on the white ink layer according to the color information in the image file to form the required pattern, and print a layer of varnish on the color ink layer to protect the printed pattern and increase the gloss. Printing white ink as a background color can enhance the saturation and contrast of the color, and printing varnish can increase the gloss while protecting the printed pattern from scratches and wear, thereby improving the overall quality and aesthetics of the printed pattern on the back cover of the mobile phone.

[0087] In summary, the mobile phone back shell printing processing method in this embodiment first defines the relative position relationship between the hollow baffle and the mobile phone back shell, so that the hollow part of the hollow baffle overlaps with the to-be-printed area of ​​the mobile phone back shell, performs surface tension modification treatment on the to-be-printed area, sets a coating on the to-be-printed area, and controls the printer to print ink on the coating in the to-be-printed area. The adhesion of the printing ink on the mobile phone back shell is improved, so that the printed pattern is not easy to wear or fall off, and while printing exquisite patterns, other parts of the mobile phone back shell are protected, and the printing accuracy is high and the printing effect is good.

[0088] Example 2

[0089] Embodiment 2 of the present invention discloses a method for printing and processing mobile phone back shells, which is suitable for printing patterns on a large number of mobile phone back shells at the same time to improve printing efficiency. When there are multiple mobile phone back shells, the relative position relationship between the limited hollow baffle plate and the mobile phone back shell is made so that the hollow part of the first hollow baffle plate coincides with the to-be-printed area of ​​the mobile phone back shell, and also includes: fixing the multiple mobile phone back shells in a positioning jig, the positioning jig includes sub-positioning areas corresponding to the number of mobile phone back shells, and the hollow baffle includes hollow parts corresponding to the number of mobile phone back shells.

[0090] Specifically, Figure 8 As shown, the positioning fixture includes a plurality of sub-positioning areas that can be fixed, and a plurality of mobile phone back shells can be placed. The plurality of mobile phone back shells are accurately placed in the fixed groove positions of the positioning fixture. The hollow baffle can be selected as follows Figure 2 The hollow baffle in the embodiment may also be a whole hollow baffle adapted to the positioning fixture. In order to adapt to the positioning fixture, the whole hollow baffle has multiple hollow areas corresponding to the to-be-printed areas of multiple mobile phone back shells. The whole hollow baffle can be fixed on the positioning fixture by a positioning structure, such as a positioning pin, such as Fig. 9 The figure shows a whole hollow baffle plate, which can be set with Mark points. The visual recognition device can identify the Mark points to determine the hollow position, so that the pattern can be accurately printed on the back shell of the mobile phone. Similarly, the hollow baffle plate is fixed on multiple mobile phone back shells of the positioning fixture so that the hollow part of the hollow baffle plate coincides with the area to be printed on the back shell of the mobile phone, and then the area to be printed is subjected to surface tension modification treatment. The surface tension modification treatment can use any one of the surface tension modification treatment methods in Example 1, and then a coating is set in the area to be printed. Finally, the printer is controlled to print ink on the coating in the area to be printed. This method realizes the simultaneous printing process of multiple mobile phone back shells, greatly improving the efficiency of the printing process.

[0095] Coating setting module 203: used to set a coating on the area to be printed;

[0096] Ink printing module 204: used to control the printer to print ink on the coating of the area to be printed.

[0097] In summary, in the mobile phone back shell printing processing device in this embodiment, the position fixing module is used to limit the relative position relationship between the hollow baffle and the mobile phone back shell, so that the hollow part of the hollow baffle coincides with the to-be-printed area of ​​the mobile phone back shell, the modification processing module is used to perform surface tension modification processing on the to-be-printed area, the coating setting module is used to set the coating in the to-be-printed area, and the ink printing module is used to control the printer to print ink on the coating in the to-be-printed area.
