[0019] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The fully automatic three-proof coating mechanism for printed circuit boards involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] This utility model provides a fully automatic three-proof coating mechanism for printed circuit boards, including a workbench 1. Limiting plates 2 are fixedly provided at the four corners of the top surface of the workbench 1. Grooves 3 are opened on the opposite sides of the four limiting plates 2. Conveyor belts 4 are provided in the grooves of the four grooves 3. Printed circuit board bodies 5 are movably connected to the outer walls of the four conveyor belts 4. A groove 6 is opened on one side of the top surface of the workbench 1. Support frames 7 are fixedly connected to both sides of the workbench 1. Limiting grooves 8 are opened on the opposite sides of the two support frames 7.

[0021] By setting up four conveyor belts 4, which are located in four grooves 3, and the width of the four conveyor belts 4 is longer than the width of the four limiting plates 2, the two sides of the printed circuit board body 5 are located above the conveyor belts 4. The printed circuit board body 5 is placed in the middle of the worktable 1 of the left conveyor belt 4. The bottom surface of the suction cup 22 is provided with a straight tube. The printed circuit board body 5 is sucked up by the straight tube on the bottom surface of the suction cup 22 and transported to the tank 6 for dip coating. After dip coating, the suction cup 22 transports the printed circuit board body 5 to the two right conveyor belts 4. The bottom of the two right conveyor belts 4 is also part of the tank 6. After the dip coating, the printed circuit board body 5 is drained on the two right conveyor belts 4 and then transported to the dryer, thereby achieving a rapid dip coating effect and solving the problem of low production efficiency of manual dip coating and semi-automatic dip coating.

[0022] Furthermore, a threaded rod 10 is movably connected in one limiting groove 8, a support rod 13 is fixedly connected in the other limiting groove 8, a first drive motor 9 is fixedly connected to one side of a support frame 7, the transmission end of the first drive motor 9 is fixedly connected to one end of the threaded rod 10, a limiting block 11 is slidably connected in both limiting grooves 8, and a control panel 23 is fixedly connected to one side of the other support frame 7.

[0023] By setting the threaded rod 10, the operator can adjust and set the movement of the support plate 12 through the control panel 23. The control panel 23 controls the first drive motor 9 to drive the threaded rod 10 to rotate. When the threaded rod 10 rotates, it drives the limit block 11 to move in the limit groove 8. The movement of one limit block 11 drives the support plate 12 to move, and then the support plate 12 transmits the force to another limit block 11. When the other limit block 11 moves, it is limited by the support rod 13, thereby achieving the stability of the support plate 12 during movement.

[0024] Furthermore, the middle part of one limiting block 11 is threadedly connected to the outer wall of the threaded rod 10, and the middle part of the other limiting block 11 is movably connected to the outer wall of the support rod 13. Support plates 12 are fixedly connected to the opposite sides of the two limiting blocks 11.

[0025] By setting the connecting column 15, the second drive motor 18 can be controlled and set to rotate the gear body 17 through the control panel 23. The rotation of the gear body 17 meshes with several gear slots 16, thereby raising and lowering the connecting column 15, and then raising and lowering the suction cup 22 through the connecting column 15.

[0026] Furthermore, a protective block 14 is fixedly connected to the middle of one side of the support plate 12, and a connecting column 15 is movably sleeved in the middle of the protective block 14. Several gear grooves 16 are opened on one side of the outer wall of the connecting column 15, and the gear body 17 is meshed with the several gear grooves 16.

[0027] By setting up an air pump device 20, which is located on the top surface of the support plate 12 near one side, the air pump device 20 cooperates with the connecting pipe 21 so that the straight pipe under the suction cup 22 can suck up the printed circuit board body 5, thereby transporting the printed circuit board body 5 to the tank 6 for dip coating and then transporting it to the right conveyor belt 4 for draining, and finally drying it in the dryer.

[0028] Furthermore, a second drive motor 18 is connected to the middle of the gear body 17, a protective shell 19 is fixedly connected to the middle of the top surface of the support plate 12, an air pump device 20 is provided on one side of the protective shell 19, a connecting pipe 21 is fixedly connected to the bottom surface of the air pump device 20, a suction cup 22 is fixedly connected to one end of the connecting pipe 21, and the bottom end of the connecting column 15 is fixedly connected to the top surface of the suction cup 22 near one side.

[0029] By setting up control panel 23, which is located on one side of support frame 7, operators can clearly see the operation of the machine when using the equipment, thereby avoiding malfunctions.

[0030] The working principle of this utility model is as follows: Four conveyor belts 4 are located in four grooves 3, and the width of the four conveyor belts 4 is longer than the width of the four limiting plates 2. The two sides of the printed circuit board body 5 are located above the conveyor belts 4. The printed circuit board body 5 is moved from the middle of the worktable 1 of the left conveyor belt 4. The bottom surface of the suction cup 22 is provided with a straight tube. The printed circuit board body 5 is sucked up by the straight tube on the bottom surface of the suction cup 22 and transported to the tank 6 for dip coating. After dip coating, the suction cup 22 transports the printed circuit board body 5 to the two right conveyor belts 4. The bottom of the two right conveyor belts 4 is also part of the tank 6. After dip coating, the printed circuit board body 5 is drained on the two right conveyor belts 4 and then transported to the dryer, thereby achieving a rapid dip coating effect. The operator can adjust and set the movement of the moving support plate 12 through the control panel 23. The control panel 23 controls the first drive motor 9 to drive the threaded rod 10 to rotate. When the threaded rod 10 rotates, it drives the limiting block 11 to move in the limiting groove 8. The movement of the support plate 12 is driven by the movement of the support plate 11, which then transmits the force to another limiting block 11. The other limiting block 11 moves by means of the support rod 13, thereby achieving stability when the support plate 12 moves. The second drive motor 18 can be controlled and set by the control panel 23 to drive the gear body 17 to rotate. The rotation of the gear body 17 meshes with several gear slots 16, thereby raising and lowering the connecting column 15. The connecting column 15 then drives the suction cup 22 to rise and fall. The air pump device 20 is located on the top surface of the support plate 12 near one side. The air pump device 20 cooperates with the connecting pipe 21 so that the straight pipe under the suction cup 22 can hold the printed circuit board body 5, thereby transporting the printed circuit board body 5 to the tank 6 for dip coating and then transporting it to the right conveyor belt 4 for draining. Finally, it is dried in the dryer. The control panel 23 is located on one side of the support frame 7. When using the equipment, the operator can clearly see the operation of the machine, thereby avoiding malfunctions.
