[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0024] Please see Figure 1-7 As shown, this utility model is a convenient vacuum coating equipment, including a base 1, a processing box 2, and a coating machine body 3. A clamping mechanism 4 is provided on the top of the base 1. The clamping mechanism 4 includes a motor 41 fixedly connected to the top of the base 1, two support bars 42, and a rotating shaft 43 rotatably connected to the top of the base 1. The motor 41 is a servo geared motor, which can precisely control the rotation speed and angle of the output shaft. Its output shaft also has a reverse function; reversing the output shaft releases the clamping state. Simultaneously, its output shaft has a locking function, which locks the output shaft after clamping to ensure clamping stability. The motor 41 has a first gear 44 fixedly connected to the surface of its output shaft. A guide frame 45 is fixedly connected between two support bars 42. Two sliders 46 are slidably connected to the inner wall of the guide frame 45. A connecting shaft 47 is fixedly connected to the top of each slider 46. A quick-release clamping block assembly 48 is provided on the top of each connecting shaft 47. A second gear 49 and a rotating disk 410 are fixedly connected to the surface of the rotating shaft 43. Two connecting arms 411 are rotatably connected to the inner wall of the rotating disk 410. Through the adaptive clamping mechanism 4, workpieces of different sizes can be clamped in a suitable manner, making them stable and providing a good fixing effect.

[0025] The left quick-release clamping block assembly 48 includes a mounting strip 481 fixedly connected to the top of the left connecting shaft 47. A connecting block 482 and four positioning rods 483 are slidably connected to the mounting strip 481. A clamping plate 484 is fixedly connected between the connecting block 482 and the four positioning rods 483. Two bolts 485 are threadedly connected between the mounting strip 481 and the connecting block 482. The inner walls of the mounting strip 481 and the connecting block 482 are provided with two threaded grooves that are compatible with the adjacent bolts 485. At the same time, the clamping plate 484, which is directly used for clamping and needs to directly contact the workpiece, can be quickly disassembled and assembled through the quick-release clamping block assembly 48, so that it can be quickly replaced, which is convenient and fast.

[0026] The coating machine body 3 is fixedly connected to the processing box 2. In a vacuum coating equipment that is easy to operate, the coating machine body 3 is the core component for realizing the vacuum environment and automatic coating function. By integrating the vacuum system, coating source and automatic control system, it completes the entire material deposition process in the vacuum chamber. Through the pumping system such as mechanical pump and diffusion pump, it reduces the air pressure in the vacuum chamber to a high vacuum state below 10⁻³ Pa. This environment can avoid gas molecule interference, ensure the purity of the film layer, and at the same time reduce the material evaporation temperature and reduce the risk of thermal damage. The coating parameters (such as temperature, time and air pressure) can be preset to realize the fully automated operation. According to the preset program, the system automatically selects the coating source (such as electron beam evaporation or magnetron sputtering). The evaporation source heats the target material to a gaseous state, and atomic clusters are deposited on the workpiece surface through a film formation process (scattered points → island structure → wandering structure → layered growth). The rotating frame system drives the workpiece to rotate, ensuring uniform film coverage. After coating is completed, the system automatically shuts off the coating source and vacuum pump, slowly releasing the gas pressure inside the chamber. This is existing technology and will not be elaborated further in this article. The coating machine body 3 is electrically connected to an external power source and is controlled by an external program. A door hinge 5 is rotatably connected to the inner wall of the processing box 2. A door panel 6 is fixedly connected to the surface of the door hinge 5, and a handle 7 is fixedly connected to the front of the door panel 6.

[0027] The bottom of the processing box 2 is fixedly connected to four support columns 8. The design of multiple support columns 8 ensures the stability of the processing box 2 and all its structures. All four support columns 8 are fixedly connected to the top of the base 1.

[0028] The first gear 44 and the second gear 49 mesh together, with a transmission ratio of 5:1. The first gear 44 drives the second gear 49 to rotate, allowing for more precise control of the clamping force. The two connecting arms 411 are rotatably connected to adjacent connecting shafts 47.

[0029] The two quick-release clamping block assemblies 48 have the same structure and are symmetrically distributed on the top of the two connecting shafts 47. By using the two quick-release clamping block assemblies 48 together, the two clamping plates 484 can be quickly disassembled and replaced.

[0030] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0031] The working principle of this utility model is as follows: First, insert the connecting block 482 and four positioning rods 483 on the left into the mounting strip 481 on the left to initially install the left clamping plate 484 on the left mounting strip 481. Then, tighten the two bolts 485 to thread the connecting block 482 and the clamping plate 484 together, achieving quick installation of the left clamping plate 484. Continue this operation to quickly install the right clamping plate 484 as well. Then, place the coated workpiece in the middle of the two clamping plates 484, and start the motor 41 to drive the first gear 44 to rotate through the output shaft. When the first gear 44 rotates, it drives the second gear 49, causing the second gear 49 to rotate. The rotating shaft 43 rotates on the top of the base 1. When the rotating shaft 43 rotates, it drives the second gear 49 to rotate synchronously. When the second gear 49 rotates, it drives the two connecting shafts 47 through the two connecting arms 411. The two connecting shafts 47 slide in opposite directions through the two sliders 46 on the inner wall of the guide frame 45. When the two connecting shafts 47 move, they drive the quick-release clamping block assemblies 48 on both sides and bring the two clamping plates 484 closer together to clamp the workpiece. Then, by holding the handle 7, the door panel 6 is rotated in the inner wall of the processing box 2 through the door hinge 5 to close the door panel 6. Finally, the film machine body 3 is started to perform automatic coating work.
