Specific embodiments

[0020] The present utility model will be further described below in conjunction with the embodiments shown in the drawings.

[0021] A solder spraying device for an anodic aluminum-based PCB board, as Figures 1-7 shown, includes a bracket 1, a mounting box 2, a first slide rail 4, a workpiece tray 5, a motor 6, an adjustment assembly, a solder spraying machine 9 and a glue pasting mechanism. The top of the bracket 1 is fixedly connected with the mounting box 2. The front side of the mounting box 2 is open. The bottom inside the mounting box 2 is fixedly connected with the first slide rail 4. The slider of the first slide rail 4 is rotatably connected with the workpiece tray 5, which can rotate the workpiece tray 5 to adjust the angle of the PCB board. The motor 6 is installed on the top inside the mounting box 2. The output shaft of the motor 6 is connected with the adjustment assembly. The adjustment assembly is connected with the solder spraying machine 9. The glue pasting mechanism is connected to the top inside the mounting box 2. The integrated design of glue pasting and solder spraying reduces the processes and the required human resources, can reduce the overall production cost, and also reduces the risk of errors caused by human factors, improving the production efficiency.

[0022] At first, the workpiece tray 5 is located on the left side inside the mounting box 2. When performing solder spraying treatment on the PCB board, first place the PCB board on the workpiece tray 5, then perform glue pasting treatment on the edge of the PCB board through the glue pasting mechanism. After the glue pasting is completed, drive the workpiece tray 5 to move rightward to below the solder spraying machine 9 through the first slide rail 4, and then adjust the position of the solder spraying machine 9 through the adjustment assembly to facilitate solder spraying treatment on the PCB board. After the treatment is completed, take out the PCB board, and then reset the workpiece tray 5 and the solder spraying machine 9 to prepare for the next round of PCB board processing, thereby completing the glue pasting and solder spraying treatment of a PCB board.

[0023] As Figures 2-4As shown, the adjustment component includes a hinge plate 7 and a first cylinder 8. A hinge plate 7 is fixedly connected to the output shaft of the motor 6, and a first cylinder 8 is fixedly connected to the bottom of the hinge plate 7. The solder spraying machine 9 is fixedly connected to the piston rod of the first cylinder 8. The spraying angle of the solder spraying machine 9 can be adjusted through the adjustment component according to the solder spraying area required by the PCB board, which is applicable to the solder spraying treatment of different PCB boards and improves the applicability of the present solder spraying device. When performing solder spraying on the PCB board, manually rotate the connection between the hinge plate 7 and the first cylinder 8 to an appropriate angle, and then drive the hinge block to rotate through the motor 6, so that the solder spraying machine 9 can perform a complete solder spraying treatment on the PCB board.

[0024] As Figure 2 and Figure 3 shown, a groove adapted to the PCB board is opened at the top of the workpiece tray 5, and a buffer pad for protecting the PCB board is fixedly connected to the bottom of the groove. When placing the PCB board, put the PCB board into the groove of the workpiece tray 5, which can ensure the precise fixation of the PCB board on the tray and is beneficial to the gluing operation of the PCB board.

[0025] As Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 shown, the gluing mechanism includes a second slide rail 10, a third slide rail 11, a second cylinder 12, a mounting shell 13, a cover plate 14, a guide wheel 15, a rolling wheel 16, a pressing wheel 17 and a cutting mechanism. The second slide rail 10 is fixedly connected to the left side of the inner top of the mounting box body 2. A third slide rail 11 is fixedly connected to the slider of the second slide rail 10. A second cylinder 12 is fixedly connected to the slider of the third slide rail 11. A mounting shell 13 is fixedly connected to the piston rod of the second cylinder 12. A cover plate 14 is snap-connected to the front side of the mounting shell 13. A guide wheel 15, a rolling wheel 16 and a pressing wheel 17 are rotatably connected to the inner bottom of the mounting shell 13. Block-shaped protrusions are provided on the pressing wheel 17, and the block-shaped protrusions can prevent the tape from sticking to the pressing wheel 17 and interfering with gluing. Anti-slip lines are opened on the rolling wheel 16, and the rolling wheel 16 can squeeze the tape to make the tape adhere more tightly to the PCB board. A cutting mechanism for cutting the tape is connected to the bottom of the mounting shell 13.

[0026] First, take out the cover plate 14, place the tape into the installation shell 13, and then reset the cover plate 14 to fix the tape. When gluing the PCB board, tear off one end of the tape so that the smooth surface of the tape contacts the right side of the guide wheel 15 and the bottom of the rolling wheel 16 at the same time, and the adhesive surface of the tape contacts the left side of the pressing wheel 17. Drive the installation shell 13 to move downward through the second cylinder 12 to make the tape stick tightly to the PCB board, and then drive the installation shell 13 to slide to the right through the slider of the third slide rail 11. The tape is pulled and rotated, and under the combined action of the second slide rail 10, the third slide rail 11 and the second cylinder 12, the tape can glue the edges of different positions of the PCB board. After gluing, cut the tape through the cutting mechanism.

[0027] As Figure 6 and Figure 7 shown, the cutting mechanism includes a micro motor 18, a threaded rod 19 and a cutting saw blade 20. A micro motor 18 is installed at the bottom of the installation shell 13. A threaded rod 19 is fixedly connected to the output shaft of the micro motor 18. A cutting saw blade 20 is slidably connected to the bottom of the installation shell 13. Two limiting plates are fixedly connected to the bottom of the installation shell 13. The two limiting plates are respectively on the upper and lower sides of the cutting saw blade 20. The cutting saw blade 20 is threadedly connected to the threaded rod 19. After the cutting mechanism cuts the tape, the tape can still be fixed on the rolling wheel 16, and the tape will not shift after being cut, which is beneficial to subsequent gluing treatment. When the tape needs to be cut, drive the threaded rod 19 to rotate through the micro motor 18, so that the cutting saw blade 20 moves to the left to squeeze the tape, so that the serrated end of the cutting saw blade 20 cuts the tape. The serrated end of the cutting saw blade 20 leaves a tooth mark on the rolling wheel 16, and the remaining tape in the installation shell 13 is squeezed and stuck in the tooth mark, and then drive the threaded rod 19 to reverse through the micro motor 18 to reset the cutting saw blade 20.

[0028] As Figures 1-3 shown, it also includes a hinged door 3 and a bellows 21. A hinged door 3 is installed at the open front of the installation box 2. A through hole for ventilation is opened at the top of the installation box 2. A bellows 21 is installed at the top of the installation box 2. The bellows 21 is communicated with the through hole. Open the hinged door 3 and put the PCB board into the workpiece tray 5. When spraying tin on the PCB board, the hinged door 3 is in a closed state, which can prevent the tin from flying out of the installation box 2 in all directions, and use the bellows 21 to continuously pump air out of the installation box 2 to extract the scattered tin, preventing workers from inhaling tin during tin spraying and causing harm to their health.

Therefore, all equivalent changes made according to the content of the claims of the present invention should be included within the scope of the claims of the present invention.
