Description

Technical Field

[0001] The utility model belongs to the technical field of vacuum coating machines, and relates to auxiliary equipment of vacuum coating machines, in particular to an adjustable slide rail device of a material rack. Background Art

[0002] PVD vacuum coating technology utilizes physical processes such as evaporation or sputtering to ionize metal or non-metal materials under vacuum conditions. The ionized metal then deposits onto the substrate surface, forming a high-performance thin film. This technology requires rotating the part 360° within the vacuum coating machine to ensure the entire surface is coated, resulting in optimal performance.

[0003] In the prior art, parts are hung on a rotatable parts rack to achieve 360° rotation coating of parts. In order to make the parts rack accurately located in the center of the vacuum coating machine chamber, a slide rail is installed at the bottom of the vacuum coating machine chamber to make the parts rack slide along the slide rail to the center of the vacuum coating machine chamber. This requires that the bottom of the parts rack matches the width of the slide rail. One slide rail can only be adapted to one parts rack. However, depending on the coating requirements, one or more target materials are usually installed in the vacuum coating machine. When multiple target materials are installed, the target window will be smaller, and the surface of the part within the target window will be deposited with more target particles. The surface of the part outside the target window is blocked by the window and is less deposited with target particles. When encountering special-shaped or large parts, the coating effect of the part cannot be guaranteed when it is rotated on the parts rack to outside the coating range of the target window, resulting in different coating thickness on the part surface, affecting the performance of the part, which greatly limits the practical application of the vacuum coating machine.

[0004] Therefore, an adjustable material rack slide device is needed that can adapt to parts racks of various specifications, so that the parts to be coated are vertically located in the center of the target window, thereby improving the coating effect of the parts to be coated.

One end of the check plate 504 is tilted upward, and a spring is arranged below the upward tilted end of the check plate 504. When the tilted end of the check plate 504 is flattened, the upper surface height of the check plate 504 is the same as the upper surface height of the sliding base 503.

[0036] A latch groove 507 is provided on the side of the sliding base 503 away from the magnetic fluid tank 201, and the telescopic latches 505 are symmetrically arranged at both ends of the latch groove 507 of the sliding base 503.

[0039] Working principle:

[0040] See also Figure 3-Figure 5 As shown, the movable slide rail 5 moves to Figure 3-Figure 5 The three positions can realize the sliding of parts racks with various pulley spacings. When the movable slide rail 5 is in Figure 3 When the movable slide rail 5 is in the first state, the pulleys of the parts rack can be engaged with both ends of the first slide rail 401. At this time, the pulley spacing of the parts rack is the largest; when the movable slide rail 5 is in the Figure 4 When the movable slide rail 5 is in the second state, the pulleys of the parts rack can be engaged at both ends of the second slide rail 402 or at both ends of the third slide rail 403. This position can adapt to the sliding of parts racks of two specifications. Figure 5 The third state is when the pulley of the parts rack is in the position, the outermost side of the pulley of the parts rack is engaged with the outer side of the third slide rail 403, and slides to between the left slide rail 501 and the right slide rail 502 of the movable slide rail 5. At this time, the pulley spacing of the parts rack is the smallest. The above three states can adapt to four different specifications of parts rack pulleys.

[0041] By adjusting the different states of the two sets of movable slide rails 5, the pulleys on both sides of the parts rack are placed in the slide rails of the two movable slide rails 5 states, which can adapt to the pulley spacing of the parts rack of different specifications between the above four specifications.

[0042] By setting the check plate 504, the pulley of the part rack is stuck by the check plate 504 after sliding in, so that the part rack cannot slide out. By manually pressing the check plates 504 on both sides of the left slide rail 501 and the right slide rail 502, the part rack with the coating completed can slide out.

[0043] Instructions:

[0044] Step 1: pinch the two pull plates 506 on the sliding base 503 to drive the telescopic latch 505 to retract into the latch slot 507, so that the sliding base 503 resumes sliding. Adjust the two sliding bases 503 to different states according to the pulley spacing of the loading parts rack.

[0045] Step 2: Slide the parts rack along the unused track into the coating chamber 1, close the chamber door and start coating.

[0046] Step 3: After the coating is completed, open the chamber door, press the check plate 504 to a horizontal position, remove the parts rack, and complete the coating.
