[0020] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0021] Please refer to Figure 1 , Figure 2 and Figure 3 As shown, a fixture 10 for preventing sputtered coating from covering alignment marks includes a fixture body 100 and a shielding assembly 200. A limiting area 110 is provided on the fixture body 100 for limiting a substrate 20. The shielding assembly 200 is disposed on the fixture body 100 and is located on the side of the limiting area. The shielding assembly 200 includes a shielding block 210. When the substrate 20 is placed on the limiting area, the shielding block 210 is located above the alignment mark of the substrate 20, and the shielding block 210 is used to shield the alignment mark of the substrate 20.

[0022] It should be noted that the substrate 20 is placed on the limiting area 110, and at the same time, the shielding assembly 200 is provided on the fixture body 100. The alignment mark on the substrate 20 is shielded by the shielding block 210 on the shielding assembly 200, so that during the sputtered coating process, the coating material can be prevented from covering the alignment mark, which may affect the subsequent process of grasping the mark for alignment.

[0023] In an embodiment, the shielding assembly 200 further includes a mounting post 230 and a mounting block 220. The mounting post 230 is disposed on the fixture body 100, and the mounting block 220 is movably sleeved on the mounting post 230. One end of the shielding block 210 is connected to the mounting block 220, and the other end of the shielding block 210 extends toward the direction close to the limiting area, so that the shielding block 210 is located above the alignment mark. Thus, the covering of the alignment mark is realized. In this embodiment, the mounting block 220 is movably sleeved on the mounting post 230, that is, the mounting block 220 is rotatably mounted on the mounting post 230. When the substrate 20 needs to be placed on the limiting area 110, the mounting block 220 can be rotated to move the mounting block 220 to an area away from the limiting area 110. In this way, the substrate 20 can be placed into the limiting area 110. After the substrate 20 is placed on the limiting area 110, the mounting block 220 is rotated back to the upper surface of the substrate 20, so as to realize the limitation of the substrate 20. For example, the mounting post 230 can be a mounting post with a threaded structure, and the mounting post 230 is threadedly connected to the fixture body 100

[0024] Preferably, the shielding block 210 has a square structure, and the size of the shielding block 210 is larger than the size of the alignment mark of the substrate, so as to ensure that the shielding block 210 can completely cover the alignment mark and prevent the alignment mark from being covered by the coating material.

[0025] In one embodiment, a clearance hole 110 is formed in the limiting area, and a limiting boss 120 is provided on the fixture body 100. The limiting boss 120 is arranged around the periphery of the clearance hole 110 and is used to abut against the peripheral side walls of the substrate. By providing the clearance hole 110, the purpose is to reduce the contact area between the substrate 20 and the fixture body 100, so as to avoid damage to the substrate caused by foreign objects on the fixture body 100.

[0026] In one embodiment, a limiting component 300 is further included. The limiting component 300 is arranged on the fixture body 100 and is arranged around the limiting area. The limiting component 300 is used to abut and limit the substrate 20 on the limiting area. By fixing the substrate on the limiting area through the limiting component 300, the substrate 20 can be fixed between the limiting boss 120 and the limiting component 300, so as to realize the limitation of the substrate 20. In another embodiment, since the fixture body is placed vertically, a limiting slot is further provided on the opposite side of the limiting component 300. First, the substrate is placed into the limiting slot, and then the limiting component 300 abuts against the substrate 20 to form a limiting fixation.

[0027] Specifically, the limiting component 300 includes a fixed block 310, a rotating block 320 and a limiting block 330. The rotating block 320 is rotatably arranged on the fixed block 310. The limiting block is installed on the rotating block, and the limiting end of the limiting block abuts against the substrate on the limiting area. When the substrate needs to be placed on the limiting area, only the rotating block 320 needs to be flipped so that the limiting block 330 is away from the limiting area. After the substrate 20 is placed on the limiting area, the rotating block 320 is flipped back to its original position so that the limiting block 330 abuts against the surface of the substrate, thereby realizing the limitation of the substrate.

[0028] Further, two limiting blocks 330 are provided. The two limiting blocks 330 are installed on the rotating block 320, and the layout of the two limiting blocks 330 is in an "eight" - shaped structure. In this way, the stability of the substrate can be further ensured.

[0029] Further, a rotating shaft is installed on the fixed block 310, and the rotating shaft passes through the rotating block 320. That is, the rotating shaft passes through the fixed block and the rotating block respectively, so that the rotating block can rotate relative to the fixed block.

[0030] In one embodiment, a first avoidance groove 130 is formed in the fixture body 100. One side of the first avoidance groove 130 extends towards the limiting boss 120 and forms an opening. Through the first avoidance groove 130 for avoidance, it is convenient for the operator to place the substrate 20 on the limiting area or take out the substrate 20 from the limiting area.

[0031] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
