[0025] See also Figure 1-4The utility model provides a technical solution for a workpiece rotating assembly for a vacuum coating machine: it includes a circular base 1, the outer top surface of the circular base 1 is fixedly connected to the coating chamber 101 by bolts, and the interior of the coating chamber 101 is provided with a rotating assembly 2 for driving the workpiece to rotate, and the rotating assembly 2 includes a rotating shaft rod 1 201 rotatably mounted inside the coating chamber 101 and located at the center position of the outer top surface of the circular base 1, and a gear 1 202 and a gear 2 203 are fixedly mounted on both ends of the outer circumferential surface of the rotating shaft rod 1 201 respectively, and a rotating shaft rod 2 204 and a rotating shaft rod 3 205 arranged in a ring with equal intervals are rotatably mounted on the outer top surface of the circular base 1 and the inner top surface of the coating chamber 101 respectively. Gear three 206 is fixedly installed on the outer circumferential surface of shaft rod two 204, and gear four 207 is fixedly installed on the outer circumferential surface of the three rotating shaft rods three 205. The three gear threes 206 are meshingly connected with gear one 202, and the three gear fours 207 are meshingly connected with gear two 203. One end of rotating shaft rod one 201 is rotatably sleeved on the center position of the inner top surface of the coating chamber 101, and the other end of rotating shaft rod one 201 extends to the interior of the circular base 1 and is fixedly connected to the output end of the driving motor 208 fixedly installed on the inner bottom surface of the circular base 1. Circular plate one 209 and circular plate two 210 are respectively fixedly installed on the outer surfaces of the three rotating shaft rods two 204 and rotating shaft rod three 205 close to each other. Start the driving motor 208 to drive the rotating shaft 1 201 to drive the gear 1 202 and the gear to rotate, and under the meshing connection characteristics of the gears, drive the three gears 3 206 and the gear 4 207 to rotate at the same time, thereby driving the three rotating shafts 2 204 and the rotating shaft 3 205 to rotate around the rotating shaft 1 201, so that the workpieces clamped on the three circular plates 1 209 and the circular plate 2 210 can be fully coated, avoiding the uneven coating on the workpiece surface due to the workpiece being fixed in a certain direction, thereby improving the coating quality of the workpiece, and secondly, by tightening the bolts, the coating chamber 101 is separated from the circular base 1, which is convenient for its maintenance and replacement in the future.

[0026] The outer surfaces of the three circular plates 1 209 and 210 that are close to each other are all fixedly equipped with limit assemblies 3 for clamping workpieces of different sizes. The limit assemblies 3 include U-shaped blocks 301 fixedly installed on the outer surfaces of the three circular plates 1 209 and 210 that are close to each other. A threaded rod 302 is rotatably installed at the center position of the outer wall of several U-shaped blocks 301. A knob 303 is fixedly installed at one end of the threaded rod 302. The other end of the threaded rod 302 extends to the interior of the U-shaped block 301 and is rotatably connected to a compacting plate 304.

First, place the workpieces that need to be coated inside the U-shaped block 301 in sequence, then turn the knob 303 to drive the threaded rod 302 to rotate, and with the assistance of the slide rod 305, push the compacting plate 304 to move inside the U-shaped block 301, and then abut and compact the workpieces of different sizes placed inside the U-shaped block 301, thereby reducing the possibility of the workpiece falling off due to inertia during rotation, which is beneficial to improving the work efficiency of the coating process.

[0027] A sealed door 102 is pivotally mounted on the front outer wall of the coating chamber 101. A transparent window 103 is located at the center of the outer wall of the sealed door 102.

The transparent window 103 allows for timely observation of the workpiece's coating status, facilitating timely adjustments.

[0028] The working principle of the present invention is as follows: when in use, the workpieces that need to be coated are first placed in the U-shaped block 301 in sequence, and then the knob 303 is turned to drive the threaded rod 302 to rotate, thereby pushing the compacting plate 304 to move inside the U-shaped block 301, and the workpieces placed inside the U-shaped block 301 are abutted and compacted.

[0029] At the same time, hold the handle 104 and rotate the sealing door 102 to cover the outer wall of the coating chamber 101 to achieve the sealing of the coating chamber 101.

[0030] At the same time, the driving motor 208 is started to drive the rotating shaft 1 201 to drive the gear 1 202 and the gear to rotate, and under the meshing connection characteristics of the gears, the three gears 3 206 and the gear 4 207 are driven to rotate at the same time, thereby driving the three rotating shafts 2 204 and the rotating shaft 3 205 to rotate around the rotating shaft 1 201 as the center, so that the workpieces clamped on the three circular plates 1 209 and the circular plate 2 210 can be fully coated.

[0031] Secondly, the coating condition of the workpiece can be observed in time through the transparent window 103, so that the staff can make timely adjustments.

[0032] Finally, when the coating process is completed, hold the handle 104 again to open the sealing door 102, and then turn the knob 303 to drive the threaded rod 302 to rotate in the opposite direction to release the fixing effect of the compacting plate 304 on the workpiece. Then, the coated workpieces are taken out one by one for the next processing.

[0033] The above description is merely a preferred embodiment of the present invention.
