This hinders continuous operation and reduces work efficiency. This phenomenon has become a problem that urgently needs to be solved by those in the field. Utility Model Content

[0020] Please see Figure 1-3 This utility model provides a technical solution: a precision glue application device for PCB board processing, including a glue application worktable 1, movable supports 2 movably arranged on both sides of the glue application worktable 1, a movable slider 3 movably arranged on the crossbeam at the top of the movable supports 2, a glue application component 4 arranged on one side of the movable slider 3, a fixed support 5 fixedly connected to the top of the glue application worktable 1, a drive motor 6 fixedly connected to the inner wall of the fixed support 5, a drive shaft 7 fixedly connected to the output shaft of the drive motor 6 via a coupling, a drive sun gear 8 and a cooling fan blade 9 fixedly connected to the outer wall of the drive shaft 7, a planetary support 10 movably connected to the outer wall of the drive shaft 7, a driven shaft 11 movably connected to the inner wall of the planetary support 10, a movable plate 12 fixedly connected to one end of the driven shaft 11, a positioning block 13 fixedly connected to the outer wall of the movable plate 12, and a positioning block 13 fixedly connected to the other end of the driven shaft 11. Driven planetary gear 14, fixed gear ring 15 is fixedly connected to the top of the glue application table 1 near the fixed bracket 5. By setting up the glue application table 1, moving bracket 2, movable slider 3, glue application assembly 4, fixed bracket 5, drive motor 6, drive shaft 7, drive sun gear 8, cooling fan blade 9, planetary bracket 10, driven shaft 11, movable plate 12, positioning block 13, driven planetary gear 14 and fixed gear ring 15, it is convenient to drive PCB boards at different angles to be placed on top for glue application. It also allows PCB boards at other angles to be installed or removed during the glue application process, which is conducive to continuous operation and improves work efficiency. In addition, during the angle adjustment, the cooling fan blade 9 can be driven to rotate, thereby quickly cooling the glued PCB board and effectively improving the curing efficiency of the PCB board after glue application.

[0021] Preferably, the cooling fan blade 9 is linked to the driving sun gear 8 via the driving shaft 7, and there is a gap between the cooling fan blade 9 and one end of the movable plate 12. Specifically, there is a gap between the cooling fan blade 9 and the driven shaft 11, thereby ensuring the effective rotation of the cooling fan blade 9, so that cooling can be performed through the cooling fan blade 9.

[0022] Preferably, the driving sun gear 8 meshes with the driven planetary gear 14, and the driven planetary gear 14 is distributed at equal angles along the axial centerline of the driving sun gear 8. Specifically, the size of the driving sun gear 8 is larger than the size of the driven planetary gear 14, which facilitates the driving sun gear 8 to drive the driven planetary gear 14 to rotate in an accelerated state.

[0023] Preferably, the planetary support 10 is rotatably connected to the drive shaft 7 via a bearing, and the drive shaft 7 passes through the planetary support 10 via a bearing, which facilitates the support of the planetary support 10 and ensures the effective rotation of the planetary support 10.

[0024] Preferably, the planetary support 10 is arranged in a "*" shape, and the driven shaft 11 is rotatably connected to the planetary support 10 through a bearing. Specifically, the driven shaft 11 is connected to the planetary support 10 through a bearing, which facilitates the driven planetary gear 14 to drive the movable plate 12 to rotate through the driven shaft 11 when it rotates.

[0025] Preferably, the movable plate 12 is distributed at equal angles along the axial center line of the cooling fan blade 9, and a groove is formed between the movable plate 12 and the inner wall of the positioning block 13. Specifically, the positioning block 13 is symmetrically distributed at both ends of the movable plate 12, which facilitates the positioning of the PCB board through the groove formed by the movable plate 12 and the positioning block 13, and improves the stability of the PCB board adhesive application.

[0026] Preferably, the driven planetary gear 14 meshes with the inner wall of the fixed gear ring 15, and the inner wall of the fixed gear ring 15 is provided with circularly distributed through slots. Specifically, the inner wall of the through slot of the fixed gear ring 15 is provided with tooth blocks at equal angles, which facilitates the driven planetary gear 14 to revolve around the through slot of the fixed gear ring 15 while rotating.

[0027] In use, the PCB board is first fixed by the slot formed between the movable plate 12 and the positioning block 13. Then, the drive motor 6 is started, which drives the drive shaft 7 to rotate. The drive shaft 7 drives the drive sun gear 8 to rotate, which in turn drives the driven planetary gear 14 to rotate. The driven planetary gear 14 revolves by meshing with the tooth block on the inner wall of the slot of the fixed gear ring 15. Subsequently, the planetary support 10 drives the movable plate 12 at different angles to be placed under the glue application assembly 4 for glue application. This achieves the effect of multi-station fixation, which is beneficial for installing or removing PCB boards at other stations while one station is applying glue. This solves the problem of low efficiency caused by workers stopping during the glue application process.

[0028] At the same time, when the driven planetary gear 14 rotates, it will drive the movable plate 12 to rotate through the driven shaft 11, so that the movable plate 12 drives the PCB board to rotate. When the drive shaft 7 rotates, it drives the cooling fan blades 9 to rotate synchronously, so that the cooling fan blades 9 can quickly cool the rotating PCB board, so that the adhesive on the PCB board can solidify quickly, further improving the efficiency of PCB board adhesive application.
