Description
Technical Field
[0001] This utility model relates to the field of PVD preparation technology for die-cast aluminum alloys, and in particular to a novel high-efficiency PVD preparation device for die-cast aluminum alloys. Background Technology
[0002] The new high-efficiency PVD preparation device for die-cast aluminum alloys is a special coating equipment that deeply integrates physical vapor deposition technology with the processing requirements of die-cast aluminum alloy workpieces. It is optimized to address the problems of low efficiency, poor adhesion, and insufficient process adaptability of traditional PVD equipment in aluminum alloy processing.
[0003] Aluminum alloy profiles are one of the most widely used non-ferrous metal structural materials in industry, and are widely used in machinery manufacturing, transportation machinery, power machinery and aerospace industry. Aircraft fuselages, skins, compressors and other components are often made of aluminum alloys to reduce weight. Using aluminum alloys instead of steel plates for welding can reduce the structural weight by more than half. In the production process of aluminum alloy profiles, the surface needs to be polished. The traditional method is to polish them manually, which is not only labor-intensive but also inefficient.
[0004] The existing patent (publication number: CN218776347U) includes a worktable, a support, a clamping device, a left-right moving device, a front-back moving device, and a grinding and polishing device. The worktable is connected to the support and the clamping device. The support is connected to the left-right moving device and the front-back moving device. The front-back moving device is connected to the grinding and polishing device. In use, the hydraulic rod extends to push the pressure plate to clamp the material. The first motor drives the second gear and the rotating rod to rotate, causing the pad to rotate and adjust the rotation direction of the material. The second motor drives the first threaded rod to rotate, causing the sliding block to move and adjust the position of the grinding wheel. The third motor drives the third gear to rotate in the tooth groove, causing the slider to move and adjust the position of the grinding wheel. The fourth motor drives the second threaded rod to rotate, causing the sliding rod to push the grinding wheel down to approach the material. The fifth motor drives the grinding wheel to perform the grinding operation, thereby automatically completing the polishing operation of the aluminum alloy profile.
[0005] To address the aforementioned issues, existing patents have provided solutions. However, existing novel high-efficiency PVD preparation devices for die-cast aluminum alloys typically involve directly placing the aluminum alloy to be die-cast onto the top of the processing table, and then using a target assembly and heating to deposit a functional thin film on the surface of the die-cast aluminum alloy. While this method can perform film-forming operations on die-cast aluminum alloys, the film-forming efficiency is low, the function is relatively simple, and no other auxiliary effects can be achieved during the film-forming process, resulting in insufficient practicality.
[0006] To address this, a novel high-efficiency PVD preparation device for die-cast aluminum alloys is proposed. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figure 1-5 The present invention provides the following technical solution:
[0030] A novel high-efficiency PVD preparation device for die-cast aluminum alloy includes a housing 3, a preparation mechanism 1 fixedly connected to the front side of the housing 3, and auxiliary mechanisms 2 fixedly connected to the inner walls of the left and right sides of the housing 3.

The processing platform 19 is fixedly connected to the surface of the output end of the motor 18.
[0032] In this embodiment: by setting the housing 3, it can serve as a sealed frame for the equipment and is made of stainless steel to ensure the sealing of the vacuum chamber 12. By setting the preparation mechanism 1, PVD coating can be achieved. By setting the auxiliary mechanism 2, support can be provided in terms of automation control, environmental regulation, and material conveying. The two work together to achieve an integrated process of automatic feeding, vacuum coating, and precise temperature control.
[0033] Specifically, such as Figure 2 , Figure 3 , Figure 4 As shown, the auxiliary mechanism 2 includes a circulating fan 21 and a PLC controller 23. The circulating fan 21 is fixedly connected to the inner walls of the left and right sides of the housing 3, and the PLC controller 23 is fixedly connected to the front side of the housing 3.
[0034] Specifically, such as Figure 2 , Figure 3 As shown, a feeding mechanism 22 is fixedly connected to the top of the housing 3, and the bottom of the feeding mechanism 22 is fixedly connected to the inner wall of the vacuum chamber 12.
[0035] Specifically, such as Figure 2 , Figure 3 As shown, a support plate 24 is fixedly connected to the left side of the housing 3, and a vacuum pump 25 is fixedly connected to the top of the support plate 24.
[0036] In this embodiment: by setting up a feeding mechanism 22, which is a belt conveyor structure, the aluminum alloy workpiece can be automatically transported to the processing table 19, reducing manual operation. By setting up a vacuum pump 25, the vacuum level in the vacuum chamber 12 can be evacuated to the required level.
[0037] Specifically, such as Figure 3 , Figure 4 As shown, a vacuum gauge 27 is fixedly connected between the vacuum pump 25 and the vacuum chamber 12, and a temperature sensor 29 is fixedly connected to the inner rear wall of the housing 3.
[0038] Specifically, such as Figure 3 , Figure 4 As shown, a heating device 26 is fixedly connected to the rear side of the housing 3, and the front side of the heating device 26 is fixedly connected to the inner wall of the vacuum chamber 12.
[0039] In this embodiment: by setting a vacuum gauge 27, data can be monitored and fed back to the PLC controller 23 in real time; by setting a heating device 26, which can be a resistance heater, the cavity temperature can be heated to the required temperature; by setting a temperature sensor 29, the temperature can be accurately monitored to ensure the stability of the coating process.
[0040] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, a ring-shaped permanent magnet 28 is snapped into the inner wall of the preparation ring 13, and a storage box is movably connected to the front side of the housing 3.
[0041] Specifically, such as Figure 5 As shown, limit frames 4 are fixedly connected to both sides of the top of the processing table 19, and electric push rods 5 are fixedly connected to the inner wall of the limit frames 4.
[0042] In this embodiment: by setting the target assembly 11, the target material raw material for PVD coating can be provided, and the number of cathode target heads 14 distributed in a ring on the preparation ring 13 is allocated and installed according to the specific situation. By setting the ring permanent magnet 28, it can cooperate with the cathode target head 14 to enhance the plasma density and improve the coating rate. By setting the auxiliary anode 15, the electric field distribution can be adjusted to make the film deposition more uniform. By setting the motor 18, the processing table 19 can be driven to rotate to avoid uneven film thickness.
[0043] Specifically, such as Figure 5 As shown, a limit clamp is fixedly connected to one side of the electric push rod 5 facing each other, and a hydraulic rod 6 is fixedly connected to the top of the support 16.

[0045] In this embodiment: by setting an electric push rod 5 on the limiting frame 4, the limiting fixture can be driven to adaptively clamp aluminum alloy workpieces of different sizes, avoiding workpiece displacement during the coating process. By setting a hydraulic rod 6, the height of the mounting platform 17 can be adjusted to adapt to different target materials and workpiece distances, optimizing the coating effect. By setting a circulating fan 21, the airflow circulation in the vacuum chamber 12 can be promoted, improving temperature uniformity. By setting a storage box, it can be used to collect the finished products after coating, facilitating subsequent transportation.
[0046] Working Principle: When the user needs to perform PVD coating on die-cast aluminum alloy, the process parameters are first set through the PLC controller 23, such as vacuum threshold, chamber temperature, machining table 19 rotation speed, and coating time. After completion, the power is turned on and the equipment is started. The feeding mechanism 22 transports the aluminum alloy workpiece to be processed to the machining table 19 inside the vacuum chamber 12. At this time, the electric push rod 5 drives the limit clamp to clamp the workpiece, and the hydraulic rod 6 adjusts the height of the mounting table 17 to the preset position. After completion, the vacuum pump 25 starts to evacuate the chamber to the target vacuum level. The vacuum gauge 27 provides real-time data feedback. After the target is reached, the heating device 26 starts. Temperature sensor 29 monitors the cavity temperature. Once the set value is reached, target assembly 11 is activated, and cathode target head 14 generates plasma. Under the action of annular permanent magnet 28 and auxiliary anode 15, the plasma is uniformly deposited on the rotating workpiece surface. During this process, circulating fan 21 is activated and continues to work to ensure uniform cavity temperature. When the coating is completed, heating device 26 and target assembly 11 stop working, the cavity cools naturally to room temperature, vacuum pump 25 depressurizes, limit clamps are released, and feeding mechanism 22 conveys the finished product out of housing 3 and places it in storage box. If continuous processing is required, the above steps can be repeated.
[0047] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
