However, the fixed-angle spraying method is prone to dead zones and cannot achieve comprehensive and uniform spraying of the wafer surface. This not only affects the coverage of the spraying effect, but may also lead to insufficient spraying uniformity, thereby reducing the efficiency and quality of coating and developing machine spraying. To solve the above problems, we propose a multi-angle spraying device for coating and developing machines. Utility Model Content

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figures 1-4 As shown, in this embodiment, a multi-angle spraying device for a coating and developing machine includes a body 1. A support 8 is slidably connected between the inner walls of the body 1. A lifting assembly is provided inside the body 1 to move the support 8. A dispensing pipe 14 is rotatably connected between the inner walls of the support 8. An adjusting assembly is provided inside the support 8 to rotate the dispensing pipe 14. A nozzle 15 is provided on the outer side of the dispensing pipe 14. A first folding telescopic pipe 16 and a second folding telescopic pipe 28 are provided between the dispensing pipe 14 and the body 1. A liquid storage tank 2 is fixedly connected to the top of the body 1. The inner walls of the liquid storage tank 2 are fixedly connected... A partition 26 is connected to the liquid storage tank 2. A liquid inlet 3 and a glue inlet 25 are provided on one side of the liquid storage tank 2. A liquid guide pipe 4 is provided between the liquid storage tank 2 and the machine body 1. The liquid guide pipe 4 communicates with the interior of the first folding telescopic pipe 16. A spray table 7 is fixedly connected to the bottom of the inner side of the machine body 1. A liquid supply pump 17 and a glue supply pump 27 are fixedly installed between the inner walls of the liquid storage tank 2. The liquid supply pump 17 and the glue supply pump 27 are located on both sides of the partition 26. One end of the liquid guide pipe 4 extends into the interior of the liquid storage tank 2 and is fixedly connected to the output end of the liquid supply pump 17. The top end of the second folding telescopic pipe 28 extends into the interior of the liquid storage tank 2 and is fixedly connected to the output end of the glue supply pump 27.

[0023] When performing coating and developing operations in the coating and developing machine, the developer and adhesive are first injected into the storage tank 2 through the injection port 3 and the adhesive injection port 25, respectively, and separated by the partition 26. Then, the wafer is placed on the spray table 7. Subsequently, according to the spraying operation requirements, the lifting component drives the support 8 to move between the inner walls of the machine body 1, thereby adjusting the nozzle 15 to a suitable spraying height. At the same time, the adjusting component drives the dispensing pipe 14 to rotate between the inner walls of the support 8, thereby adjusting the nozzle 15 to a suitable spraying angle. Meanwhile, the machine body 1 is connected to an external power source and powered on. The controller then starts the adhesive supply pump 27, which delivers the adhesive along the guide pipe 4 and the first folded telescopic pipe 16 to the dispensing pipe 14. The nozzle 15 then uses the adhesive to evenly spray the adhesive onto the wafer, thus completing the coating operation.

[0024] After the adhesive on the wafer solidifies, the developer is pumped by the supply pump 17 along the second folded telescopic tube 28 to the distribution tube 14. Then, the developer is sprayed evenly onto the wafer in a mist form by the nozzle 15 to remove excess and uncured adhesive from the wafer, ensuring that the wafer surface is clean and tidy. This completes the developing operation and improves the spraying efficiency and quality of the spraying device.

[0025] like Figures 1-4 As shown, the adjustment assembly includes a first rotating shaft 23 and a second rotating shaft 24. The first rotating shaft 23 and the second rotating shaft 24 are rotatably connected to both sides inside the bracket 8. One end of the first rotating shaft 23 and the second rotating shaft 24 are fixedly connected to the liquid separator 14. A worm gear 13 is fixedly connected to the outer side of the first rotating shaft 23. A mounting plate 9 and an auxiliary plate 10 are fixedly connected to one side inside the bracket 8. A worm 11 is rotatably connected between the mounting plate 9 and the auxiliary plate 10. The worm 11 meshes with the worm gear 13. An adjustment motor 12 is fixedly installed on one side of the mounting plate 9. The output end of the adjustment motor 12 passes through the mounting plate 9 and is fixedly connected to the worm 11.

[0026] By adjusting the motor 12 to drive the worm gear 11 to rotate between the mounting plate 9 and the auxiliary plate 10, and by utilizing the meshing between the worm gear 11 and the worm wheel 13, the first rotating shaft 23 is driven to rotate. Then, in conjunction with the second rotating shaft 24, the liquid distribution pipe 14 is driven to rotate between the inner walls of the bracket 8, thereby improving the spraying effect of the spraying device.

[0027] like Figures 1-4As shown, the lifting assembly includes a lifting groove 5 and a guide groove 18. The lifting groove 5 and the guide groove 18 are respectively opened on both sides inside the body 1. A threaded rod 6 is rotatably connected between the inner walls of the lifting groove 5. A lifting block 21 is threadedly connected to the outer side of the threaded rod 6. One side of the lifting block 21 is fixedly connected to the bracket 8. A guide rod 19 is fixedly connected between the inner walls of the guide groove 18. A guide block 22 is slidably connected to the outer side of the guide rod 19. One side of the guide block 22 is fixedly connected to the bracket 8. A lifting motor 20 is fixedly installed on the top of the body 1. The output end of the lifting motor 20 extends into the interior of the lifting groove 5 and is fixedly connected to the threaded rod 6.

[0028] The lifting motor 20 drives the threaded rod 6 to rotate between the inner walls of the lifting groove 5, thereby driving the lifting block 21 to move. In conjunction with the guide block 22 that moves on the guide rod 19 inside the guide groove 18, the bracket 8 is driven to move between the inner walls of the body 1, thereby improving the adjustment flexibility of the spraying device.

[0029] This utility model provides a multi-angle spraying device for a coating and developing machine. The specific working principle is as follows: When the coating and developing machine is performing coating and developing operations, the developing solution and adhesive are first injected into the storage tank 2 through the injection port 3 and the adhesive injection port 25 respectively, and separated by a partition 26. Next, the wafer is placed on the spraying table 7. Then, according to the spraying operation requirements, the machine body 1 is connected to an external power source and powered on. The controller then starts the lifting motor 20, which drives the threaded rod 6 to rotate between the inner walls of the lifting groove 5, thereby driving the lifting block 21 to move. This, in conjunction with the guide block 22 moving on the guide rod 19 inside the guide groove 18, drives the... The bracket 8 moves between the inner walls of the machine body 1 to adjust the nozzle 15 to a suitable spraying height. At the same time, the motor 12 drives the worm gear 11 to rotate between the mounting plate 9 and the auxiliary plate 10. The meshing between the worm gear 11 and the worm wheel 13 drives the first rotating shaft 23 to rotate. Then, in conjunction with the second rotating shaft 24, the liquid distribution pipe 14 is driven to rotate between the inner walls of the bracket 8, thereby adjusting the nozzle 15 to a suitable spraying angle. Meanwhile, the glue supply pump 27 delivers glue along the liquid guide pipe 4 and the first folded telescopic pipe 16 to the liquid distribution pipe 14. The nozzle 15 then uses the glue to evenly spray the glue onto the wafer, thus completing the glue coating operation.

[0030] After the adhesive on the wafer solidifies, the developer is pumped by the supply pump 17 along the second folded telescopic tube 28 to the distribution tube 14. Then, the developer is sprayed evenly onto the wafer in a mist form by the nozzle 15 to remove excess and uncured adhesive from the wafer, ensuring that the wafer surface is clean and tidy. This completes the developing operation and enables the use of the multi-angle spraying device.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
