Through the coordinated operation of the above devices, the entire dual-station laser engraving and matte finish integrated solution for the smartphone mid-frame and the automated post-laser engraving oiling solution are completed.

[0038] The principle of this utility model is:

[0039] The servo motor at station A moves the product to the center of the laser, while station B loads and unloads the product. After the laser engraving of the product at station A is completed, station A moves to the waiting position, and station B moves to the center of the laser for laser engraving. Station A then starts loading and unloading the product. The laser-engraved product is placed on the sandblasting fixture on the rotating table inside the 2D sandblasting machine. A clean, dust-free cloth is wrapped around the wiping head, and the automatic oil spraying device is set to spray protective oil onto the wiping head once at a certain interval. The start button is pressed, and the wiping head begins to rotate at high speed. The rotating worktable begins to rotate, moving the product to the designated position. The wiping head then begins to apply the protective oil evenly to the surface of the phone's frame according to the set trajectory.

[0040] This invention enables dual-station servo motors and laser engraving machines to be connected to a computer for signal linkage, thereby achieving dual-station operation, reducing waiting time for loading and unloading materials, and improving production efficiency; it also utilizes a 2D sandblasting machine to achieve automatic oiling, replacing manual oiling, increasing efficiency by 200%, and ensuring product quality.

[0041] To more clearly demonstrate the technical solution and effects provided by this utility model, the following detailed description of the embodiments of this utility model is provided with reference to specific examples.

[0042] Example 1

[0043] like Figure 1 , Figure 2 As shown:

[0044] The preferred embodiment of the dual-station laser engraving and matte finish solution for the mid-frame of a smartphone and the automated post-laser engraving oiling device of this utility model is as follows:

[0045] Turn on the laser engraving machine beforehand, open the engraving software, bring up the laser engraving drawing of the mobile phone frame, set the process parameters, open the control panel, and start the equipment reset.

[0046] After all the motors and pressing cylinders are reset, place the mobile phone frame on the engraving fixture 4 / 7 of station A / B, press the start button, and the pressing cylinder 1 / 9 of station A / B will push the pressing fixture 2 / 8 of station A / B to fix the product on the engraving fixture 4 / 7 of station A / B.

[0047] After the equipment detects that the pressing cylinders 1 / 9 of stations A and B have reached their positions, the servo motor 5 of station A moves the product on the engraving fixture 4 to the designated position to begin four-sided laser engraving. After the laser engraving is completed, the product returns to the waiting position, and the pressing cylinder 1 of station A opens. After the equipment detects that the product on the engraving fixture 4 of station A has returned to the waiting position, the servo motor 6 of station B begins to move the product on the engraving fixture 7 of station B to the designated position to begin four-sided laser engraving, and the product on the engraving fixture 4 of station A begins loading and unloading. After the laser engraving at station B is completed and the product returns to the waiting position, the servo motor 5 of station A again moves the product on the engraving fixture 4 of station A to the designated position to begin laser engraving, and the product on the engraving fixture 7 of station B begins loading and unloading, and so on.

[0048] Turn on the 2D sandblasting machine 11, and the equipment will begin to reset. Open the mobile phone frame oiling drawing, install the laser-engraved mobile phone frame onto the oiling fixture 14, wrap a clean lint-free cloth around the oiling head 12, and use the automatic oiling device 13 to spray protective oil onto the lint-free cloth on the oiling head 12. Press the start button, and the sandblasting machine's rotating worktable 15 will move the oiling fixture 14 to the designated position. The oiling head will begin to rotate at a high speed and move along the trajectory set in the drawing, evenly applying the protective oil to the surface of the mobile phone frame. After wiping, the sandblasting machine's rotating worktable 15 will start to rotate, moving the product on the other oiling fixture 14 to the designated position to begin the oiling operation. The wiped product returns to the loading position, and the loading and unloading operation begins, repeating this process.

[0049] In the oiling assembly of the sandblasting machine:

[0050] 1. The oil wiping head 12 includes a metal shaft core, which can be connected to the central shaft of the servo motor to achieve high-speed rotation, and can be quickly replaced using a quick connector; sponges can be attached to the upper and lower parts of the metal shaft core, such as two sponges with a width of 18mm and a thickness of 6mm, and wrapped with an anti-static dustproof cloth.

[0051] 2. The oil wiping action is performed synchronously by the rotational and vertical movements of the servo motor. The oil wiping head is fixed on the central shaft of the servo motor, which can achieve high-speed rotation. At the same time, the servo motor module is installed on the Z-axis vertical motion module, which can achieve synchronous vertical movement.

[0052] 3. The 2D sandblasting machine comes with an X / Y / Z three-axis module. The servo motor is mounted on the three-axis module. The motion trajectory program can be programmed through motion control software. The X / Y / Z three-axis module moves the wiping head according to the set motion trajectory program. The X / Y axis determines the planar motion trajectory of the wiping head, and the Z axis determines the up and down movement of the wiping head.

[0053] 4. The 2D sandblasting machine comes with a four-station turntable, with a product positioning fixture installed at each station. When the third station is performing oiling operations, the first station is operated by manual or robotic arms to pick up and place products. The second and fourth stations are operated in the same way, alternating between stations.

[0054] This invention enables automated dual-station laser engraving and matte finish production of smartphone mid-frames, as well as automated post-laser engraving oiling, improving production efficiency and product yield, avoiding product defects, and generating significant economic benefits.

[0055] In this embodiment of the invention, the laser engraving machine and sandblasting machine were purchased commercially. Specifically:

[0056] 1) The moving device of the A station component and the B station component of the laser engraving machine is not the inventive point of this application. Any solution in the prior art can be adopted. For example, the simplest option is to place the moving trolley on the guide rail and then install the relevant parts on the trolley, so that it can move on the guide rail.

[0057] 2) The relationship between the engraving component and the sandblasting component is not the inventive point of this application. The positional relationship between the engraving component and the sandblasting component is sufficient to satisfy the requirement that "the laser-engraved product is placed on the sandblasting fixture". Generally, the parts can be picked up and placed by a robot arm, or the most rudimentary manual picking up and placing is also acceptable, with no special requirements.

[0058] 3) This application essentially comprises two steps:

[0059] Process 1, glossy and matte laser engraving, the so-called "glossy and matte in one body" means that one part is glossy (formed by other processes) and the other part is matte laser engraving. This application improves the existing matte laser engraving technology from a single station to a dual station. There are two stations, one for matte laser engraving and the other for picking up and placing parts, which are carried out alternately, thus improving efficiency.

[0060] Step 2, Automatic Oiling: This application implies an inventive point, namely, improving the existing sandblasting machine into an oiling machine;

[0061] The sandblasting machine 11 was originally used for sandblasting, and the rotating worktable 15 of the sandblasting machine was originally used to place the parts to be sandblasted; their positions corresponded. This application improves upon this by:

[0062] The rotating worktable 15 of the sandblasting machine is equipped with multiple oiling fixtures 14 around its perimeter for fixing the laser-engraved machine housing; the sandblasting machine 11 is equipped with an oiling head 12 and an automatic oil spraying device 13, the automatic oil spraying device 13 sprays oil onto the oiling head 12, the oiling head 12 is used for oiling.

[0063] The above description is merely a preferred embodiment of this utility model, but the scope of protection of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this utility model should be included within the scope of protection of this utility model. Therefore, the scope of protection of this utility model should be determined by the scope of the claims. The information disclosed in the background section is intended only to enhance the understanding of the overall background technology of this utility model and should not be construed as an admission or implication in any way that such information constitutes prior art known to those skilled in the art.
