Description

Technical Field

[0001] The utility model relates to the technical field related to filling devices, in particular to an automatic filling device for triple-proof paint. Background Art

[0002] Conformal coating, also known as circuit board protective paint, moisture-proof oil or moisture-proof paint, is a special coating used on electronic circuit boards. Conformal coating is often used in outdoor electronic equipment, military equipment, aerospace equipment, industrial control systems, automotive electronics, etc. After the production of conformal coating, it needs to be filled into special bottles or cans to prevent it from being solidified due to long-term exposure to the air.

[0003] Since the conformal coating has a certain viscosity, impurities may be mixed into the coating during its production process and form granular solids. However, existing automatic filling devices usually do not have the function of filtering impurities. Therefore, these granular solid impurities can easily block the nozzle of the filling head when passing through the filling head, resulting in the inability to fill the conformal coating normally.

A sliding pad 10 is arranged in the placement seat 9 and a spring 11 is arranged between the pad 10 and the bottom plate of the placement seat 9. A rotatable blocking rod 12 is arranged on one side of the placement seat 9.

[0028] Among them, a mounting frame 13 fixed on the top plate of the workbench 1 is arranged between the storage tank 2 and the turntable 8, an electric push rod 14 is arranged at the top of the mounting frame 13, and an electric-controlled filling head 15 that can slide up and down is arranged at the upper end of the mounting frame 13, and the output end of the mounting frame 13 is fixed on one side of the electric-controlled filling head 15. By arranging the mounting frame 13 and the electric push rod 14, the electric push rod 14 can drive the electric-controlled filling head 15 to slide up and down when working.

[0029] Among them, the position of the electric-controlled filling head 15 corresponds to the position of the placement seat 9 on the turntable 8, and the electric-controlled filling head 15 is connected to the liquid outlet end of the liquid pump 4. By setting the electric-controlled filling head 15, the liquid pump 4 can transport the paint liquid in the storage tank 2 to the electric-controlled filling head 15, and then the electric-controlled filling head 15 fills the paint liquid into the filling bottle placed in the placement seat 9 below it.

[0030] Among them, a dust cover 16 is provided at the top of the storage tank 2, the liquid pump 4 is placed on the upper surface of the dust cover 16, and the liquid suction pipe 5 on the liquid inlet end of the liquid pump 4 passes through the dust cover 16 and enters the storage tank 2. By setting the dust cover 16, the paint liquid in the storage tank 2 can be protected from external pollution, and the installation and fixation of the liquid pump 4 can be facilitated.

[0031] Among them, one end of the filter cartridge 6 located inside the storage tank 2 is provided with dense filter holes for filtering impurities, the end of the filter cartridge 6 located outside the storage tank 2 is provided with a waste outlet 17 and a sealing cover is provided on the waste outlet 17, and one end of the central axis of the spiral blade rod 7 extends to the outside of the filter cartridge 6 and is fixedly connected with a handle.

[0033] Among them, a limit rod is provided at the center of the lower surface of the pad 10, which slides through the bottom plate of the corresponding placement seat 9, and a limit plate is provided on the limit rod below the pad 10, which is in contact with the lower surface of the placement seat 9. A protruding rod 21 is provided on one side of the lower end of the baffle rod 12, which touches the lower surface of the pad 10 when the baffle rod 12 is in an inclined state. By arranging the limit rod and the limit plate under the pad 10, the pad 10 can be prevented from resetting too quickly when it is affected by the elastic force of the spring 11. By arranging the protruding rod 21 on the baffle rod 12, the pad 10 can be pressed The protruding rod 21 can rotate the baffle rod 12 to a vertical state during the downward pressing process, allowing the upper end of the baffle rod 12 to fit on the filling bottle.

Since the filter cartridge 6 is provided with filter holes, impurities in the paint liquid can be filtered out to ensure that the paint liquid conveyed by the liquid extraction pump 4 is pure. After that, the paint liquid will be conveyed to the electric control filling head 15 under the action of the liquid extraction pump 4. When cleaning the impurities in the filter cartridge 6, it is only necessary to open the sealing plug on the waste outlet 17 and drive the spiral blade rod 7 to rotate by the handle, so that the impurities in the filter cartridge 6 can be pushed to the waste outlet 17 for discharge, which is simple and convenient to operate.

Due to the meshing relationship between the worm gear 18 and the worm 20, the servo motor 19 can drive the turntable 8 to rotate at a suitable angle, ensuring that the filling bottle in the placement seat 9 will be located directly below the electric filling head 15 after each rotation, and then the electric push rod 14 will drive the electric filling head 15 to move downward, and the injection nozzle at the lower end of the electric filling head 15 will enter the bottle mouth at the upper end of the filling bottle, and the electric filling head 15 will press the filling bottle down for a distance, and the pad 10 will be pressed to move downward, causing the spring 11 to be compressed, and because the pad 10 and the protruding rod 21 on the baffle rod 12 are matched, the baffle rod 12 can be rotated to a vertical state by pressing the protruding rod 21 at the lower end of the baffle rod 12 during the downward movement of the pad 10, so that the upper end of the baffle rod 12 can be attached to the filling bottle for reinforcement, preventing the bottle body from shaking due to the impact of the paint liquid during filling;

[0036] After the filling is completed, the electric filling head 15 will rise again driven by the electric push rod 14. In the process of the electric filling head 15 moving away from the filling bottle, the pad 10 and the filling bottle thereon will be reset under the elastic force of the spring 11. The limit rod and the limit sheet are arranged under the pad 10 to prevent the pad 10 from resetting too quickly when it is affected by the elastic force of the spring 11. When the pad 10 no longer presses the protruding rod 21 at the lower end of the baffle rod 12, the baffle rod 12 will rotate to a tilted state again, which is convenient for taking out the filling bottle.
