[0030] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model and not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0031] REFERENCE Figures 1-2 An embodiment provided by the utility model: a robot suction cup device, including bottom plate 1, the upper surface of bottom plate 1 is fixedly connected with vacuum pump 2, the bottom surface of bottom plate 1 is fixedly connected with vacuum chuck 3, vacuum pump 2 and vacuum chuck 3 are connected through hose, vacuum pump 2 can carry out air extraction inside vacuum chuck 3 when starting, so that vacuum chuck 3 can generate negative pressure inside, and then the adsorption of the article can be realized, the structure is all prior art means in the field, and here is not described repeatedly, the bottom surface of vacuum chuck 3 is fixedly connected with rubber ring 4, rubber ring 4 can increase the contact area of the bottom of vacuum chuck 3 and the surface of the article, so that vacuum chuck 3 can better adhere to the object.

[0032] Referring to Figures 1-3 The outer side of the bottom plate 1 is detachably connected with the side plate 5, and the bottom plate 1 can drive the side plate 5 to move synchronously when moving. The bottom surface of the side plate 5 is provided with a pressing plate 6. An extrusion unit is arranged above the pressing plate 6. The extrusion unit comprises a telescopic rod 61 which is fixedly connected to the upper surface of the pressing plate 6. The pressing plate 6 can drive the telescopic rod 61 to move synchronously when moving. Meanwhile, the telescopic rod 61 can guide and limit the movement of the pressing plate 6, so that the pressing plate 6 can only move in a straight line in the up-down direction. The upper end of the telescopic rod 61 is fixedly connected to the bottom surface of the side plate 5. A spring 62 is sleeved outside the telescopic rod 61. A telescopic hose 63 is sleeved outside the spring 62. The upper and lower ends of the spring 62 and the telescopic hose 63 are respectively fixedly connected to the upper surface of the pressing plate 6 and the bottom surface of the side plate 5. When the pressing plate 6 moves upward, the telescopic rod 61 and the spring 62 will be extruded, so that the spring 62 is compressed to generate elastic potential energy. The telescopic hose 63 can protect the outside of the telescopic rod 61 and the spring 62, avoiding dust and impurities from falling into the inside of the spring 62, which affects the compression of the spring 62.

[0033] A circular hole 7 is formed in the upper surface of the pressing plate 6. A rubber ring 4 is sleeved in the circular hole 7. A rubber pad 8 is fixedly connected to the bottom surface of the pressing plate 6. A through hole which is matched with the circular hole 7 is formed in the bottom surface of the rubber pad 8. The rubber pad 8 can avoid the hard contact between the pressing plate 6 and the rubber ring 4, and can prolong the service life of the rubber ring 4. In the initial state, the pressing plate 6 and the rubber pad 8 will slightly extrude the rubber ring 4 under the action of the elastic potential energy of the spring 62, so that the rubber ring 4 is in a downward arc bending state.

[0034] When the bottom plate 1 moves downward so that the vacuum chuck 3 and the rubber ring 4 are attached to the surface of the object, the rubber ring 4 will reset to the unfolded state, and at the same time will extrude the pressing plate 6, so that the pressing plate 6 extrudes the spring 62 upward, so that the spring 62 is compressed to generate elastic potential energy. When the rubber ring 4 and the vacuum chuck 3 are attached to the surface of the object, and the vacuum pump 2 is started to extract the air in the vacuum chuck 3 to adsorb and take the object, the pressing plate 6 will extrude the rubber ring 4 under the action of the elastic potential energy of the spring 62, so that the rubber ring 4 can be more closely attached to the surface of the object. When the rubber ring 4 and the vacuum chuck 3 are worn or deformed at the edge after long-term use, the pressing plate 6 can still make the rubber ring 4 and the vacuum chuck 3 closely attached to the surface of the object when extruding the rubber ring 4 and the vacuum chuck 3, which can prolong the service life of the rubber ring 4 and the vacuum chuck 3.

[0035] Referring to Figures 3-4The upper surface of the side plate 5 is fixedly connected with a connecting plate 9, the side plate 5 moves to drive the connecting plate 9 to move synchronously, the outer surface of the connecting plate 9 is provided with a screw hole 10, the upper surface of the bottom plate 1 is fixedly connected with a mounting plate 11, the bottom surface of the mounting plate 11 is provided with a slot 12, the connecting plate 9 is inserted into the slot 12, and the connecting plate 9 is preliminarily limited after being inserted into the slot 12; the outer side of the mounting plate 11 is provided with a bolt 13, the size of the bolt 13 is matched with the size of the screw hole 10, one end of the bolt 13 near the mounting plate 11 penetrates through the mounting plate 11, and the one end of the bolt 13 near the mounting plate 11 is in threaded connection with the inner screw hole 10; after the connecting plate 9 is completely inserted into the slot 12, the bolt 13 is aligned with the screw hole 10, the bolt 13 is screwed into the screw hole 10, and then the connecting plate 9 and the side plate 5 can be directly fixed, and the operation is simple; when the vacuum chuck 3 needs to be overhauled and replaced, the bolt 13 is directly unscrewed to release the fixation of the connecting plate 9, so that the pressing plate 6 and the side plate 5 can be directly disassembled, thereby facilitating the overhaul.

[0036] Working principle: when the bottom plate 1 drives the vacuum chuck 3 and the rubber ring 4 to move downward and adhere to the surface of an article, the rubber ring 4 pressed and bent downward by the pressing plate 6 can return to the relaxed state, and the pressing plate 6 is pressed at the same time, so that the pressing plate 6 moves upward and the spring 62 is pressed, so that the spring 62 is compressed to generate elastic potential energy; at this time, the pressing plate 6 can press the rubber ring 4 under the action of the elastic potential energy of the spring 62, so that the rubber ring 4 can better adhere to the surface of the article; when the rubber ring 4 and the vacuum chuck 3 are worn or deformed at the edge after long-term use, the pressing plate 6 can still make the rubber ring 4 and the vacuum chuck 3 tightly adhere to the surface of the article when the pressing plate 6 presses the rubber ring 4 and the vacuum chuck 3, so that the service life of the rubber ring 4 and the vacuum chuck 3 can be prolonged; when the vacuum chuck 3 needs to be overhauled and replaced, the bolt 13 is unscrewed to release the fixation of the connecting plate 9 and the side plate 5, so that the pressing plate 6 can be removed, the overhaul is facilitated, and the operation is simple.
