Description

Technical Field

[0001] This utility model relates to the field of PCB board cleaning technology, specifically to a PCB board surface tornado dust removal and cleaning position adjustment structure. Background Technology

[0002] In the electronics manufacturing industry, PCB (Printed Circuit Board) cutting is a crucial process. Although PCB depaneling machines are equipped with dust extraction devices during the cutting process, due to the characteristics of tiny dust particles and electrostatic adsorption, some dust remains on the PCB surface after cutting, making effective removal difficult. Chinese Patent CN220920260U discloses a fully automatic multi-functional PCB cleaning machine, belonging to the technical field of PCB processing equipment. This invention includes a roller brush dust extraction module, an adhesion module, and an ion bar, all horizontally mounted above a conveyor. The adhesion module is installed in a drawer-type configuration with the frame. A touchscreen and an electrical control box are respectively installed at the top and bottom of the frame. The touchscreen, conveyor, adhesion module, roller brush dust extraction module, and ion bar are all electrically connected to the electrical control box. This invention uses a roller brush dust extraction module, adhesion module, and ion bar to perform multiple cleaning processes on the PCB and remove static electricity. The contact cleaning method effectively eliminates poor soldering conditions such as cold solder joints, open solder joints, warping, and misalignment, thereby reducing potential problems and improving product quality. The distance between the adhesion cylinder and the roller in the adhesion module is adjusted by spring elasticity to remove dust from PCBs of different thicknesses, and an adjustable conveying device is used to clean PCBs of different sizes.

[0003] The existing technologies described above have the following shortcomings: When cleaning the surface of a PCB board, the existing technologies use roller brushes, adhesion cylinders, and ionizing air bars to clean dust and static electricity. Since the positions of these components are fixed, it is difficult to adjust the optimal cleaning position for PCB boards of different sizes. Therefore, a PCB board surface tornado dust removal and cleaning position adjustment structure is provided to solve the above problems. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] Please refer to the following: Figures 1-6 This utility model discloses a PCB board surface tornado dust removal and cleaning position adjustment structure, including: a top adjustment mechanism 3 and a bottom adjustment mechanism 7. The top adjustment mechanism 3 and the bottom adjustment mechanism 7 are the same size and structure. The bottom adjustment mechanism 7 includes a Z-axis lead screw module and an X-axis lead screw module. The Z-axis lead screw module includes a base plate 10, a servo motor 11, a limit frame 12, a first lead screw 13, and a lifting plate 14. The servo motor 11 and the limit frame 12 are both fixedly installed on the top of the base plate 10. The two ends of the first lead screw 13 are respectively connected to the top of the limit frame 12 and the inside of the base plate 10 through bearings. The first lead screw 13 is threaded through the back side of the lifting plate 14. The X-axis lead screw module includes a bearing seat 17, a second lead screw 18, a crank 19, a guide block 21, and a movable plate 20. The second lead screw 18 is connected to the inside of the bearing seat 17 through bearings. The crank 19 is connected to one end of the second lead screw 18. One side of the movable plate 20 is slidably connected to the inside of the guide block 21. The second lead screw 18 is threadedly connected to one side of the movable plate 20.

[0023] Combination Figure 2 and Figure 6As shown, the shaft seat 17 and the guide block 21 are both fixedly connected to one side of the lower fixed frame 8. The bottom tornado dust removal component 9 is installed on one side of the upper end of the lower fixed frame 8. The output end of the top adjustment mechanism 3 is connected to the upper fixed frame 4. The top tornado dust removal component 5 is installed inside the lower end of the upper fixed frame 4. The limit frame 12 is located on one side of the lifting plate 14 and is set on the side cover plate 15. The output end of the servo motor 11 and the first lead screw 13 are both connected to the pulley through the bottom plate 10. The pulley or gear is connected to the chain. The output end of the servo motor 11 and the first lead screw 13 are connected through the bottom plate 10 by the pulley winding belt.

[0024] The base plate 10 is equipped with a dust cover 16 on one side of the belt pulley. The lifting plate 14 is fixedly connected to one side of the movable plate 20 by screws. The bottom adjustment mechanism 7 is fixedly connected to the fixed frame 6 by screws through the limit frame 12.

[0025] Specifically, when the Z-axis adjustment of the top tornado dust removal component 5 or the bottom tornado dust removal component 9 is performed, the corresponding servo motors 11 of the top adjustment mechanism 3 and the bottom adjustment mechanism 7 can be operated to drive the pulley to rotate. The pulley drives the pulley on the first lead screw 13 to rotate through the belt, thereby causing the first lead screw 13 to rotate. The first lead screw 13 can then threadedly drive the lifting plate 14 to move up and down. The lifting plate 14 can then drive the movable plate 20 to rise and fall. The movable plate 20 can then synchronously rise and fall with the upper fixed frame 4 / lower fixed frame 8 connected on one side. The upper fixed frame 4 / lower fixed frame 8 can then adjust the height position of the top tornado dust removal component 5 and the bottom tornado dust removal component 9.

[0026] When adjusting the top tornado dust removal component 5 or the bottom tornado dust removal component 9 along the X-axis, the crank handle 19 can be manually turned to drive the second lead screw 18 to rotate. The second lead screw 18 then moves along the movable plate 20, and the upper fixed frame 4 / lower fixed frame 8 connected to the guide block 21 and the shaft seat 17 can move in the X-direction. Similarly, the upper fixed frame 4 / lower fixed frame 8 can adjust the horizontal position of the top tornado dust removal component 5 and the bottom tornado dust removal component 9, thus facilitating the adjustment to the optimal position for PCB boards of different sizes and specifications.
