Description

Technical Field

[0001] This utility model relates to the field of OLED manufacturing technology, and in particular to a mask support frame for OLED evaporation. Background Technology

[0002] High-pixel displays have not yet entered the Chinese market, largely due to the extreme difficulty in designing and manufacturing precision photomasks. Substandard precision photomasks have resulted in a large number of defective high-pixel display products, a problem that is difficult to solve.

[0003] Currently, the fabrication of precision photomasks involves welding horizontal shielding strips and vertical support strips onto the photomask frame. Then, segmentation photomasks are welded onto the photomask frame with the horizontal shielding strips and vertical support strips. The function of the horizontal shielding strips is to shield the gaps between the segmentation photomasks, while the vertical support strips mainly serve to support the segmentation photomasks and reduce their deformation. Since the welding of the horizontal shielding strips and vertical support strips requires external force to stretch them before welding them onto the photomask frame, this installation method is extremely inconvenient, requires multiple people to operate, and involves a large amount of labor. Utility Model Content

[0027] Please see Figure 1-6This utility model provides a technical solution: a mask support frame for OLED evaporation deposition, including a frame 1, a first connecting plate 2 on the right side of the frame 1, a first mounting plate 4 on the left side of the frame 1, a plurality of transverse shielding strips 3 fixedly connected to the left side of the first connecting plate 2, a first limiting groove 5 opened at the top of the frame 1 near the left and right sides, the transverse shielding strips 3 fixedly connected to the right side of the first mounting plate 4, the transverse shielding strips 3 movably passing through adjacent first limiting grooves 5, and a second connecting plate 14 on the rear side of the frame 1. The frame 1 has a second mounting plate 16 on the front side, and a number of vertical support bars 15 are fixedly connected to the front side of the second connecting plate 14. The top of the frame 1 is provided with second limiting grooves 17 near the front and rear sides. The vertical support bars 15 are fixedly connected to the rear side of the second mounting plate 16. The vertical support bars 15 can move through the adjacent second limiting grooves 17. The top of the horizontal blocking strip 3 is provided with a number of first grooves 18, and the bottom of the vertical support bars 15 is provided with a number of second grooves 19. The first grooves 18 and the second grooves 19 match each other.

[0028] Two limiting rods 12 are fixedly connected to the left side of the first connecting plate 2 and the front side of the second connecting plate 14. Two limiting holes 13 are opened on the rear and right sides of the frame 1. The limiting rods 12 are movably inserted into the inner cavity of the adjacent limiting holes 13. The limiting rods 12 and the limiting holes 13 match each other. A limiting frame 6 is provided on the left side of the first mounting plate 4 and the front side of the second mounting plate 16. A threaded sleeve 7 is fixedly inserted on the limiting frame 6. A screw 8 is passed through the inner cavity of the threaded sleeve 7. A bearing 9 is fixedly sleeved on one end of the screw 8. The two bearings 9 are fixedly connected to the first mounting plate 4 and the second mounting plate 16 respectively. The bearing 9 is located at the end of the screw 8 away from the nut. Two through holes 10 are opened on the first mounting plate 4 and the second mounting plate 16. Two blind holes 11 are opened on the left side and the front side of the frame 1. The limiting frame 6 movably passes through the adjacent through holes 10 and is movably inserted into the inner cavity of the adjacent blind holes 11. The cross-section of the limiting frame 6 is U-shaped.

[0029] Working principle: This utility model discloses a mask support frame for OLED evaporation. During use, the first connecting plate 2, the horizontal shielding strip 3, and the first mounting plate 4 are moved as a whole. The horizontal shielding strip 3 is inserted into the corresponding first limiting groove 5. At the same time, the limiting rod 12 on the first connecting plate 2 corresponds to the adjacent limiting hole 13. Then, the first connecting plate 2, the horizontal shielding strip 3, and the first mounting plate 4 are moved horizontally to the left, so that the limiting rod 12 on the first connecting plate 2 is inserted into the adjacent limiting hole 13. The first connecting plate 2 and the right side of the frame 1 are in contact with each other. At this time, the limiting bracket 6 on the first mounting plate 4 corresponds to the blind hole 11 on the left side of the frame 1. Then, the screw 8 on the first mounting plate 4 is turned. The screw 8 rotates in the inner cavity of the threaded sleeve 7 and the bearing 9. The threaded sleeve 7 drives the limiting bracket 6 to move. The limiting bracket 6 moves to the inner cavity of the blind hole 11, thereby fixing the first connecting plate 2, the horizontal shielding strip 3, and the first mounting plate 4 as a whole onto the frame 1.

[0030] Next, move the second connecting plate 14, vertical support bar 15, and second mounting plate 16 as a whole, so that the second groove 19 at the bottom of the vertical support bar 15 corresponds to the first groove 18 at the top of the horizontal blocking bar 3. Then, move the second connecting plate 14, vertical support bar 15, and second mounting plate 16 as a whole downward, so that the second groove 19 and the first groove 18 engage with each other. At this time, the limiting rod 12 on the second connecting plate 14 corresponds to the adjacent limiting hole 13. Then, move the second connecting plate 14 and the vertical support bar 15 forward. The second mounting plate 16 and the second connecting plate 14 are integrated together, so that the limiting rod 12 on the second connecting plate 14 is inserted into the inner cavity of the limiting hole 13. The second connecting plate 14 moves to fit against the rear side of the frame 1. Then, the screw 8 on the second mounting plate 16 is turned. The screw 8 rotates in the inner cavity of the threaded sleeve 7 and the bearing 9. The threaded sleeve 7 drives the limiting frame 6 to move. The limiting frame 6 moves to the inner cavity of the blind hole 11, thereby fixing the second connecting plate 14, the vertical support bar 15, and the second mounting plate 16 as a whole onto the frame 1.

[0031] After the horizontal shielding strip 3 and the vertical support strip 15 are installed, a mask plate is installed on the top of the device;

[0032] The device uses the limiting rod 12 and the limiting hole 13 to work together, so that the horizontal blocking strip 3 and the vertical support strip 15 can be installed more quickly and accurately. In addition, the limiting frame 6 is moved by rotating the screw 8 and inserted into the cavity of the adjacent blind hole 11, thereby fixing the horizontal blocking strip 3 and the vertical support strip 15. The operation is simple, the amount of labor is small, and it is suitable for widespread use.

[0033] The device, through the setting of the first groove 18 and the second groove 19, ensures that after the horizontal shielding strip 3 and the vertical support strip 15 are installed, the first groove 18 and the second groove 19 can limit the horizontal shielding strip 3 and the vertical support strip 15, and also ensure that the top of the horizontal shielding strip 3 and the vertical support strip 15 are in a flush state, thereby facilitating the installation of the mask plate on the top of the device.
