Description

Technical Field

[0001] This utility model belongs to the field of fluoroboric acid filling technology, and specifically relates to a filling device. Background Technology

[0002] Fluoroboric acid is a colorless liquid with a melting point of -90℃ and a boiling point of 130℃. It is miscible with water or alcohol. Fluoroboric acid is used for cleaning and corrosion of oxides and silicate films on metal surfaces, and for cleaning aluminum and alloys before electroplating. It is also used as a conductive liquid in lead-tin electroplating and as a catalyst and metal surfactant. Existing filling devices mostly use a single-head filling mode, processing only one storage bottle at a time. Failure of such single-head filling equipment can lead to production stoppages, failing to meet the needs of large-volume filling. Furthermore, existing filling devices are inconvenient for heat-sealing storage bottles, increasing the workload for subsequent workers. Therefore, we propose a new filling device.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 and Figure 2As shown, this utility model embodiment provides a filling device, including a first conveyor belt 1, a filling mechanism 2 is provided on the rear side of the first conveyor belt 1, a heat sealing mechanism 3 is provided on one side of the first conveyor belt 1, a second conveyor belt 4 is provided on one side of the heat sealing mechanism 3, and a control panel 5 is provided on the front side of the first conveyor belt 1. The filling mechanism 2 includes a first filling rack 201 and a second filling rack 203 disposed on the rear side of the first conveyor belt 1. A storage tank 202 is mounted on the surface of the first filling rack 201, and a connecting valve is mounted on the surface of the storage tank 202. A transfer tank 204 is mounted on the upper surface of the second filling rack 203. A longitudinally adjustable first electric cylinder 205 is mounted on the surface of the second filling rack 203. A movable seat 206 is mounted on the surface of the piston rod of the first electric cylinder 205. A plurality of filling heads 207 are mounted on the surface of the movable seat 206. The transfer tank 204 is connected to the plurality of filling heads 207 through a plurality of first conveying pipes 208. A booster pump 209 is mounted on the surface of the first filling rack 201. The booster pump 209 is connected to the storage tank 202 and the transfer tank 204 through a second conveying pipe 210. In this specific embodiment, multiple storage bottles can be transported by the first conveyor belt 1. Then, the first electric cylinder 205 starts its piston rod to drive the moving seat 206 and the filling head 207 to descend. The booster pump 209 starts to transport the fluoroboric acid inside the storage tank 202 to the interior of the transfer tank 204 through the second conveying pipe 210. Then, the fluoroboric acid is transported to the filling head 207 through the first conveying pipe 208, and then filled through the filling head 207. After filling, the filled storage bottles are heat-sealed by the heat-sealing mechanism 3.

[0026] Please see Figure 1 and Figure 2 As shown, mounting seats 6 are installed on the surfaces of both the first conveyor belt 1 and the second conveyor belt 4, and protective rods 7 are fixedly connected to the inner sides of the two mounting seats 6. The combined use of the mounting seats 6 and the protective rods 7 guides the storage bottles moving on the surfaces of the first conveyor belt 1 and the second conveyor belt 4, thereby reducing the probability of the storage bottles scattering. The surface of the nozzle of the filling head 207 is coated with polytetrafluoroethylene (PTFE), and a ceramic valve core is installed on the inner side of the nozzle. The PTFE coating and ceramic valve core increase the corrosion resistance of the filling head 207, thereby increasing its service life.

[0027] Please see Figure 1 and Figure 2 As shown, a first servo motor 211 is mounted on the surface of the cover plate of the storage tank 202. A rotating shaft 212 is fixedly connected to the surface of the output shaft of the first servo motor 211 inside the storage tank 202. Multiple stirring paddles 213 are fixedly connected to the surface of the rotating shaft 212. The first servo motor 211 is started, and its output shaft drives the rotating shaft 212 to rotate. The rotating shaft 212 drives the stirring paddles 213 to rotate, thereby stirring the fluoroboric acid inside the storage tank 202.

[0028] Please see Figure 1 and Figure 2 As shown, two guide rods 214 are fixedly connected to the surface of the movable seat 206. The guide rods 214 are slidably connected to the upper surface of the second filling rack 203, and a limiting ring 215 is provided on the surface of the guide rods 214. The movement of the movable seat 206 causes the guide rods 214 to slide on the surface of the second filling rack 203, thereby increasing the stability of the movable seat 206 during movement. The limiting ring 215 reduces the probability of the guide rods 214 slipping off the surface of the second filling rack 203.

[0029] Please see Figure 3 and Figure 4 As shown, the heat sealing mechanism 3 includes a heat sealing table 301 disposed on one side of the first conveyor belt 1.

Two second electric cylinders 307 are mounted on the surface of the heat sealing frame 304. A heat sealing pressure plate 308 is mounted on the surface of the piston rod of the second electric cylinder 307. Specifically, in this embodiment, multiple storage bottles can be transported via the first conveyor belt 1. Then, the first electric cylinder 205 starts its piston rod to drive the moving seat 206 and the filling head 207 to descend. The booster pump 209 starts to transport the fluoroboric acid inside the storage tank 202 to the interior of the transfer tank 204 through the second conveying pipe 210. Then, the fluoroboric acid is transported to the filling head 207 through the first conveying pipe 208, and then filled through the filling head 207. After filling, the storage bottles are moved by the electric turntable 302 and the chuck 303. The second servo motor 310 starts its output shaft to rotate, driving the second pulley 311 to rotate. At this time, under the action of the transmission belt 312 and the first pulley 309, the winding roller 305 is driven to rotate. The rotation of the winding roller 305 can drive the heat sealing film to be wound up. Then, the second electric cylinder 307 starts its piston rod to drive the heat sealing plate 308 to move, thereby heat sealing the upper surface of the storage bottle.

[0030] Please see Figure 3 and Figure 4As shown, a first pulley 309 is mounted on the surface of the take-up roller 305, a second servo motor 310 is mounted on the surface of the heat sealing frame 304, and a second pulley 311 is mounted on the surface of the output shaft of the second servo motor 310.
