[0028] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner, and thus only show components related to the present invention.
[0029] Please refer to Figure 1-4 A suction cup for automatic weighing of pole pieces includes an upper shell 1, an inner core 2 and a plurality of patches 3. The inner core 2 is arranged inside the upper shell 1, and the upper shell 1 is fixedly connected to the inner core 2. The plurality of patches 3 are arranged around the upper shell 1 and on the bottom surface of the inner core 2. The surface of the upper shell 1 is provided with a blowing hole 11 and a blowing hole 2 12. The blowing hole 11 is connected to the air jet holes 26 around the inner core 2, and the blowing hole 2 12 is vertically arranged and passes through the inner core 2.
[0030] The suction cup is used for picking up the pole piece during weighing. When in use, the bottom of the suction cup is close to the surface of the pole piece, and then the air enters the inner core 2 from the blowing hole 11, and then is ejected to the surroundings through the jet hole 26, while the blowing hole 2 12 is injected into the hollow space just below the suction cup. During the fluid flow process, the gas flow rate is compressed and increased inside the inner core. According to the Bernoulli principle, the air pressure flowing through the gap decreases, thereby forming a low-pressure area between the suction cup and the pole piece, and the surrounding air pressure drop is higher, thereby pushing the pole piece to the low-pressure area, so that the pole piece is adsorbed by the suction cup, which is convenient for taking and placing the pole piece during the weighing process.
[0031] Please refer to the structure of the upper shell 1 Figure 5-6A step 14 is provided inside the upper shell 1, and the inner core 2 is installed in the step 14. An outward-inclined slope 15 is provided around the step 14, and the jet hole 26 corresponds to the slope 15; that is, the jet hole 26 sprays air onto the slope 15. Since the slope 15 is inclined outward, the compressed air adjusts the flow angle and diffuses, thereby increasing the adsorption strength and adsorption area of the low-pressure area, making it more stable when adsorbing the electrode.
[0032] The structure of the inner core 2 can be found in Figure 7-8 The surface of the inner core 2 is provided with a boss 1 21 and a boss 2 22. The setting of the boss 1 21 and the boss 2 22 is to better match the step 14 in the upper shell. The boss 1 21 and the boss 2 22 are both provided with an assembly hole 24. The boss 1 21 is also provided with a through hole 23. The through hole 23 corresponds to the blowing hole 2 12, and the assembly hole 24 corresponds one-to-one with the connecting hole 13.
[0033] When the inner core 2 is assembled with the upper shell 1, the surfaces of boss 1 21 and boss 2 22 contact the inner top surface of the upper shell 1, and the surface of the inner core 2 contacts the surface of the step 14. At this time, the through hole 23 corresponds to the blowing hole 2 12, and the assembly hole 24 corresponds to the connecting hole 13 one by one, and then the two are fixedly connected at the connecting hole 13 by screws; after connection, since boss 1 21 and boss 2 22 are higher than the surface of the inner core 2, a cavity 25 is formed around boss 1 21 and boss 2 22, and the jet holes 26 are evenly arranged around the inside of the cavity 25, that is, one end of the jet hole 26 is connected to the cavity 25, and the other end is connected to the outside, wherein the blowing hole 11 is connected to the cavity 25 between boss 1 21 and boss 2 22.
[0034] At this time, when air is blown into the first blowing hole 11, the air first enters the narrow cavity 25, is compressed in the cavity, increases the flow rate, and flows out from the air jet hole 26 and diffuses. When air is blown into the second blowing hole 12, the internal vacuum environment is broken, which facilitates a better adsorption effect.
[0035] Based on the above embodiment, the inner diameter of the through hole 23 gradually decreases from top to bottom in order to increase the air flow rate.
[0036] For the structure of patch 3, please refer to Figure 9 , the multiple patches 3 are fixed on the upper shell 1 and the inner core 2 by gluing.
[0037] There is a gap between each two adjacent patches 3 at the bottom of the upper shell 1, and the air injection hole 26 corresponds to the gap; please refer to the following for details. Figure 10 There is a gap between each two adjacent patches, and the air injection hole 26 is set between the two patches so that it corresponds to the gap, which facilitates the air flow to flow and diffuse outward from the gap, improves the internal low pressure effect, and increases the adsorption strength.
[0038] Based on the above embodiment, corresponding avoidance notches 4 are provided on the upper shell 1 and the patch 3. The avoidance notches 4 are semicircular. The avoidance notches 4 are provided to facilitate the overall coordination of the suction cup with the external device to avoid position conflicts with the external device.
[0039] Based on the above embodiment, the patch 3 is made of PP material, PVC material, PE material or FRP material, and has acid-proof and corrosion-resistant effects. When in use, the suction cup adsorbs the electrode, and after adsorption, the electrode adheres to the bottom surface of the patch. Since the patch is acid-proof and corrosion-resistant, it can also effectively protect the electrode; the thickness of the patch 3 is 1 mm.
[0040] Based on the above embodiment, the holes on both sides of the surface of the upper shell 1 are sensor bracket mounting holes, the sensor bracket mounting hole is 4×M4, the overall width of the suction cup is 60mm, the length is 120mm, the inner diameter of the avoidance gap is 15mm, and the blowing hole 11 and the blowing hole 2 12 are externally connected to the φ6 air pipe.
[0041] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
