[0047] Figure 1 is a schematic diagram of a capping device according to an embodiment of the present invention. Figure 2 A schematic cross-sectional view is shown below.

[0048] See also Figure 1 as well as Figure 2 As shown in the figure, the capping device 100 includes a power shaft 110, a capping cover 120 and a bottle cap holder 160. The power shaft 110 is connected to the capping cover 120 to drive the capping cover 120 to rotate so as to open or close the bottle cap 220 of the bottle 200. In addition, the capping cover 120 includes an opening 130, and the bottle cap holder 160 is installed in the opening 130 of the capping cover 120 to clamp the bottle cap 220 of the bottle 200.

[0049] In some embodiments, the bottle cap holder 160 includes a gas pressure expansion ring 162, and the volume of the gas pressure expansion ring 162 can be changed according to the gas pressure, thereby clamping or loosening the bottle cap 220 of the bottle 200. Then, the bottle cap 220 of the bottle 200 is rotated in cooperation with the power shaft 110 and the cap screw cover 120 to open or close the bottle cap 220 of the bottle 200.

[0050] In some embodiments, the bottle cap holder 160 further includes a corrosion-resistant contact layer 164 disposed on the inner side of the gas pressure expansion ring 162. The corrosion-resistant contact layer 164 may be a perfluoroalkyl (PFA) contact layer to prevent the corrosive liquid from corroding the gas pressure expansion ring 162, thereby increasing the service life of the capping device 100.

[0051] In some embodiments, the PFA contact layer is a thermoplastic fluorine resin with excellent chemical, electrical and mechanical properties, and can avoid corrosion by most chemical liquids, and is a material with high chemical stability. In addition, the PFA contact layer is also suitable for continuous contact with highly active chemical liquids to increase the service life of the capping device 100.

[0052] In some embodiments, the surface of the corrosion-resistant contact layer 164 is formed with concave-convex textures to increase friction.

[0053] In some embodiments, the surface of the corrosion-resistant contact layer 164 is formed with concavo-convex patterns, and the concavo-convex patterns are complementary to the side patterns of the bottle cap 220 to increase the torsional force of rotating the bottle cap 220 .

[0054] In some embodiments, a first guiding portion 140 , a bottle body receiving area 180 , a second guiding portion 150 and a bottle cap receiving area 170 are sequentially disposed in the opening 130 of the screw cap cover 120 .

[0055] The first guide portion 140 is connected to the bottle body receiving area 180 to guide the bottle body 210 of the bottle 200 so that the bottle body 210 stably and correctly enters the bottle body receiving area 180. In addition, when the bottle cap 220 passes through the first guide portion 140, the first guide portion 140 can also effectively guide the position of the bottle 200 to guide the bottle body 210 and the bottle cap 220 of the bottle 200 to align with the center of the opening 130 of the screw cap cover 120.

[0056] In addition, the second guide portion 150 is connected to the bottle cap receiving area 170 to guide the bottle cap 220 of the bottle 200 to enter the bottle cap receiving area 170 correctly and stably. The bottle cap holder 160 is disposed in the bottle cap receiving area 170. When the bottle cap 220 correctly enters the bottle cap receiving area 170, the air pressure expansion ring 162 is activated so that the air pressure expansion ring 162 and the corrosion-resistant contact layer 164 clamp the bottle cap 220. Then the power shaft 110 rotates the capping cover 120 to rotate the bottle cap 220 of the bottle 200, thereby opening the bottle cap 220 of the bottle 200. In addition, the bottle cap holder 160 can also hold the opened bottle cap 220, and after the bottle 200 is injected with the required chemical liquid, the bottle cap 220 is rotated in the opposite direction to fit the bottle cap 220 to the bottle body 210 of the bottle 200.

[0057] In some embodiments, the power shaft 110 further has the function of moving up and down, so as to move the screw-on cover 120 and the bottle cap 220 held therein up and down.

[0058] In some embodiments, the bottle body 210 has a bottle body shoulder 240, and the bottle cap 220 has a bottle cap top 250, and the bottle body shoulder 240 and the bottle cap top 250 preferably have arc edges, so that the first guide portion 140 and the second guide portion 150 can guide the bottle 200 to align with the center of the screw-on cover 120.

[0059] In some embodiments, the height 101 of the bottle cap receiving area 170 plus the second guiding portion 150 is preferably greater than or equal to the height 102 from the bottle cap top 250 of the bottle cap 220 to the bottle body shoulder 240 of the bottle body 210 to enhance the stability and accuracy of the guidance.

[0060] In some embodiments, the capping device 100 further includes a bottle cap sensor 190 disposed in the bottle cap receiving area 170 of the capping cover 120 for detecting whether the bottle cap 220 of the bottle 200 is correctly positioned in the opening 130 of the capping cover 120 .

[0061] In some embodiments, the bottle cap sensor 190 can be a limit switch, a proximity switch, an optical sensor, a laser sensor and / or an infrared sensor to detect whether the bottle cap 220 of the bottle 200 is correctly positioned in the opening 130 of the screw cap cover 120, and can also detect the position of the bottle 200 in advance to improve the accuracy and stability of the passage, all of which do not depart from the spirit and protection scope of the present invention.

[0062] In some embodiments, the bottle 200 can be used to contain hydrofluoric acid (HF) solution, nitric acid solution, phosphoric acid solution, acetic acid solution, hydrogen peroxide solution, deionized water (DI water) and / or sulfuric acid solution required for sampling, but the present invention is not limited to this.

[0063] In summary, the capping equipment can safely and conveniently open or close the bottle caps to facilitate the acquisition of samples of chemical liquids used in semiconductor production lines, reduce the probability of human or environmental contamination, and improve the efficiency and accuracy of sample extraction, thereby increasing the yield and output of semiconductors, thereby increasing the revenue and profits of semiconductor production.
