Description

Technical Field

[0001] This utility model relates to the field of PVD electroplating technology, specifically to a PVD electroplating suspension fixture structure. Background Technology

[0002] PVD electroplating, or Physical Vapor Deposition, is an advanced surface treatment technology widely used in various fields. PVD electroplating is a technique that, under vacuum conditions, vaporizes the material source surface into gaseous atoms, molecules, or partially ionized ions using physical methods, and then deposits a thin film with specific functions onto the substrate surface through a low-pressure gas or plasma process. PVD electroplating is mainly divided into three categories: vacuum evaporation coating, vacuum sputtering coating, and vacuum ion plating. The basic principle of PVD electroplating includes three steps: vaporization of the plating material, migration of plating material atoms, molecules, or ions, and deposition of plating material atoms, molecules, or ions onto the substrate.

[0003] PVD electroplating produces virtually no harmful substances, resulting in minimal environmental pollution and aligning with green production and sustainable development requirements. It can deposit various materials onto diverse substrates, such as metals, alloys, and ceramics. PVD electroplating can produce high-purity, highly crystalline, and strongly adhesive thin films, suitable for aerospace, electronics, optics, machinery, and many other fields. PVD electroplating is widely used in decorative coatings, such as surface coatings for mobile phone cases, watches, jewelry, and eyeglasses. It is also used to deposit hard films on the surfaces of tools, drill bits, and molds, improving hardness, wear resistance, and corrosion resistance. Furthermore, PVD electroplating is used to deposit conductive and semiconductor thin films to improve the photoelectric conversion efficiency of solar cells. In semiconductor manufacturing, PVD electroplating is used to deposit metal and insulating films, significantly impacting chip performance and reliability.

[0004] In the common PVD electroplating process, the workpiece needs to be suspended inside the PVD electroplating machine using a suspension fixture. The PVD electroplating machine drives the suspension fixture to rotate, causing the workpiece to rotate inside the PVD electroplating machine, thus ensuring uniform electroplating. However, common suspension fixtures can only install workpieces by suspension, and some workpieces do not have suspension points, making it difficult to suspend them for electroplating. In view of this, this application proposes a PVD electroplating suspension fixture structure. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a PVD electroplating suspension fixture structure, which has the advantages of placing workpieces on the top of the mounting base and intermediate box for PVD electroplating. It solves the problem that common suspension fixtures can only install workpieces by suspension, and some workpieces do not have suspension points, making it difficult to suspend them for electroplating.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a PVD electroplating suspension fixture structure, including a mounting base box, a bottom support rod fixedly mounted on the top of the mounting base box, two overlapping intermediate boxes provided on the top of the bottom support rod, a middle support rod fixedly mounted on the top of the intermediate boxes, a top plate fixedly mounted on the top of the upper middle support rod, a middle hook fixedly mounted on the bottom of the intermediate boxes, and a top hook fixedly mounted on the bottom of the top plate;

[0007] A middle partition is fixedly installed on the inner side wall of the middle box. Four middle turntables are rotatably installed on the top of the middle box. Four middle transmission wheels are rotatably installed on the top of the middle partition. The top of the middle transmission wheels is fixedly connected to the bottom of the middle turntable. Adjacent middle transmission wheels are connected by belt drive.

[0008] Furthermore, an intermediate motor is fixedly installed at the bottom of the intermediate partition, and the output shaft of the intermediate motor is fixedly connected to the bottom of one of the intermediate transmission wheels.

[0009] Furthermore, an intermediate battery is fixedly installed at the bottom of the intermediate partition, an intermediate charging port adapted to the intermediate battery is fixedly installed on the surface of the intermediate housing, and an intermediate anti-slip pad is fixedly installed on the top of the intermediate turntable.

[0010] Furthermore, a bottom partition is fixedly installed on the inner side wall of the mounting base box, and four bottom turntables are rotatably installed on the top of the mounting base box, with bottom anti-slip pads fixedly installed on the top of the bottom turntables.

[0011] Furthermore, four bottom drive wheels are rotatably mounted on the top of the bottom partition, the top of the bottom drive wheels are fixedly connected to the bottom of the bottom turntable, and adjacent bottom drive wheels are connected by belt drive.

[0012] Furthermore, a bottom motor is fixedly installed on the bottom of the bottom partition, the output shaft of the bottom motor is fixedly connected to the bottom of one of the bottom transmission wheels, a bottom battery is fixedly installed on the bottom of the bottom partition, and a bottom charging port adapted to the bottom battery is fixedly installed on one side of the mounting box.

[0013] Furthermore, support side plates are fixedly installed on the two mutually distant sides of the mounting base box, and mounting screws are threaded onto the top of the support side plates. A movable wheel is rotatably installed at one end of the mounting screw located at the bottom of the support side plate via a wheel frame, and an adjustment knob is fixedly installed at the top of the mounting screw.

[0014] Compared with the prior art, this utility model provides a PVD electroplating suspension fixture structure, which has the following beneficial effects:

[0015] This PVD electroplating suspension fixture structure features a rotatable central turntable at the top of the central housing, with an anti-slip pad on top of the turntable. Besides suspending the workpiece, it can also place the workpiece on top of the anti-slip pad for PVD electroplating. During the PVD electroplating process, the central turntable rotates, causing the workpiece to rotate, resulting in more uniform electroplating. This solves the problem of common suspension fixtures that only allow workpieces to be installed by suspension, and where some workpieces lack suspension points, making it difficult to suspend them for electroplating.

[0025] An intermediate battery 9 is fixedly installed at the bottom of the intermediate partition 31, and an intermediate charging port 10 adapted to the intermediate battery 9 is fixedly installed on the surface of the intermediate housing 3.
