Description

Technical Field

[0001] The present invention belongs to the technical field of mobile phone middle frame processing, and specifically relates to a mobile phone middle frame processing technology. Background Art

[0002] As the name implies, the mobile phone middle frame is an important framework part of the mobile phone, located between the front panel and the back cover of the mobile phone; it carries various components inside the mobile phone, such as batteries, motherboards, cameras, flexible cables, various sensors, microphones, speakers, etc., and is the "skeleton" for these components to be fixed and installed; at the same time, the mobile phone middle frame also plays a role in protecting the internal components of the mobile phone, preventing them from being impacted and damaged by the outside world.

[0003] In the processing of existing mobile phone middle frames, it is usually necessary to perform electroplating treatment to ensure the luster of the mobile phone middle frame. However, during long-term use, the pH value of the electroplating solution will change, resulting in the phenomenon of thickening or insufficient thickness of the electroplating layer of the mobile phone middle frame, leading to the thickness of the mobile phone middle frame not meeting the standard and reducing the quality of the mobile phone middle frame. Summary of the Invention

[0004] To achieve the above object, the present invention provides the following technical solution: A mobile phone middle frame processing technology, including the following steps:

[0005] Step 1, forming processing: Take a metal blank, heat it to an appropriate temperature, put it into a mold, and apply a huge pressure through a forging device to form the metal material in the mold into a mobile phone middle frame.

[0006] Step 2, laser cutting processing: Use a laser beam with a high energy density to irradiate the mobile phone middle frame material, so that the material melts or vaporizes instantly, thereby achieving the purpose of cutting, and cutting the mobile phone middle frame into a specified shape.

[0007] Step 3, cleaning of the mobile phone middle frame: Clean the surface of the processed mobile phone middle frame to remove surface oil, dust, and metal debris. Usually, ultrasonic cleaning is used, and the cavitation effect generated by ultrasonic waves in the liquid is used to peel off impurities from the surface of the object to achieve the purpose of efficient cleaning.

[0008] Step 4, electroplating processing: Use the electrolysis principle to deposit a layer of metal or alloy on the surface of the mobile phone middle frame, so as to obtain good gloss and decoration on the surface of the middle frame, thereby improving the corrosion resistance and oxidation resistance of the mobile phone middle frame.

[0009] Step 5, quality inspection: Screen the quality of the mobile phone middle frame through appearance inspection, dimensional accuracy inspection, structural strength inspection, and function inspection, and remove products that do not meet the requirements.

[0011] Step 1: Take multiple test tubes and place them on a test tube rack.

[0012] Step 2: Use a dropper to suck electrolyte solutions from different positions and drop them into the multiple test tubes respectively, with the electrolyte solution covering 1 / 3 of the test tube.

[0013] Step 3: Use a pH meter to measure the pH values in the multiple test tubes and record them.

[0014] Step 4: Calculate the average value of multiple groups of pH values to obtain the final pH value.

It should be noted that when adding, it needs to be added slowly, and at the same time, the solution is continuously stirred to make the acid solution fully mixed with the solution evenly, avoiding local over-acidity.

[0016] As a further embodiment of the present invention, when the pH value of the electrolyte solution in Step 4 is too low, usually an alkaline regulator is added. It should be noted that when adding, it needs to be added slowly, and at the same time, the solution is fully stirred to make the alkaline substances evenly dispersed, preventing the local pH value from being too high.

[0017] As a further embodiment of the present invention, the preparation of the electrolyte solution in Step 4 includes the following steps:

[0018] Step 1: Dissolve the main salt: Add the calculated main salt into an appropriate amount of deionized water, heat while stirring to accelerate the dissolution of the main salt; and the heating temperature is controlled at 40 - 60 °C.

[0019] Step 2: Add complexing agent and additives: According to the formula requirements, add the complexing agent in sequence to improve the performance of the electroplating solution, and various additives. The additives are used to improve the quality and appearance of the coating. When adding, it should be noted to add slowly and stir fully to ensure its uniform dissolution in the solution;

[0020] Step 3: Adjust the pH value: Use a pH meter to measure the pH value of the solution and adjust it with acid or alkali as needed;

[0021] Step 4: Supplement water and make up the volume: After dissolving and adding all components, according to the total volume requirement of the solution, make up to the required scale with deionized water to make the solution reach the specified volume.

[0022] Compared with the prior art, the beneficial effects of the present invention are:
