[0002] In the production process of liquor, some stations in the process of screening and feeding cylindrical bottle caps rely on manual picking, which is monotonous in nature and reduces efficiency over long periods of time. Industrial robots can be used to replace manual labor, improve efficiency, and achieve automation. Due to the different types of wine bottles, the sizes of cylindrical bottle caps are different, and some bottle caps have protrusions on the bottom. When conveyed on the belt line, the axis of the bottle cap will have a certain inclination angle with the normal direction of the belt, and the inclination directions of different bottle caps will also be different.

[0045] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention application are described in detail below in conjunction with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures, or characteristics in one or more embodiments may be combined in any suitable form.

[0046] In the description of the present invention, it should be clarified that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, but are not necessarily used to describe a specific order or sequence; the terms "vertical", "lateral", "longitudinal", "front", "rear", "left", "right", "up", "down", "horizontal", etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention, and do not mean that the referred device or element must have a specific direction or position, and therefore cannot be understood as a limitation on the present invention.

[0047] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] like Figure 8 and 9 As shown, in the production process of liquor, some stations in the process of screening and loading cylindrical bottle caps (material 10) are manually picked up, the nature of the work is single, and the efficiency is reduced for a long time. Industrial robots can be used to replace manual labor, improve efficiency, and realize automation. Due to the different types of wine bottles, the sizes of cylindrical bottle caps are different, and some bottle caps have some protrusions 101 on the bottom. When conveyed on the belt line, the axis of the bottle cap will have a certain tilt angle with the normal direction of the belt of the belt line 11, and the tilt directions of different bottle caps will also be different. If only a single suction component is used to suck the bottle caps, it is difficult to ensure that the bottle caps at different angles are sucked at the same angle at the same position of the suction suction component after suction, resulting in low material picking efficiency and interference during assembly, resulting in a low assembly success rate.

[0049] Example 1

[0050] like Figure 1-7 As shown, an embodiment of the present invention provides a material taking mechanism, and the material taking mechanism includes:

[0051] Mounting plate 1,

[0052] A suction assembly 2, which is telescopically arranged on the mounting plate 1;

[0053] A correction component 3 connected to both the mounting plate 1 and the suction component 2;

[0054] When the suction component 2 retracts, it can drive the correction component 3 to correct the material 10 clamped by itself, so that the axis of the material coincides with the preset position of the suction component 2 in the extension direction. The preset position can be a position parallel to or coincident with the axis of the suction component 2.

[0055] In this embodiment, the material picking mechanism includes a mounting plate 1, a suction component 2 and a correction component 3. The suction component 2 is retractably arranged on the mounting plate 1. The suction component 2 can absorb the material 10 when it is retracted and moved. After the absorption is completed, the mounting plate 1 is driven by the moving mechanism to move the material 10. The correction component 3 is connected to both the mounting plate 1 and the suction component 2. Since the suction component 2 of this embodiment can drive the correction component 3 to correct the material 10 clamped by itself when it retracts, the axis of the material 10 coincides with the preset position of the retracting direction of the suction component 2. The retracting direction of the suction component 2 is vertical and upward and downward, and the preset position can be parallel to or coincide with the axis of the suction component 2. Therefore, it can be ensured that materials 10 of different sizes and angles are all adsorbed at the same position of the suction component 2 at the same angle, which is convenient for the material picking mechanism to accurately position the material 10, and the material picking mechanism does not need to reposition the material 10, thereby improving the material picking efficiency and assembly success rate of the material picking mechanism.

[0056] In some embodiments, the suction component 2 includes a telescopic drive unit 21 and an adsorption unit 22. The telescopic drive unit 21 is arranged on the mounting plate 1. The telescopic drive unit 21 has a telescopic part 211 that can be telescoped. The adsorption unit 22 is arranged at the end of the telescopic part 211 to adsorb the material 10.

[0057] In this embodiment, the telescopic driving unit 21 is set on the mounting plate 1, and the adsorption unit 22 is set at the end of the telescopic part 211 of the telescopic driving unit 21 of the adsorption component 2. The telescopic part 211 of the telescopic driving unit 21 of the adsorption component 2 is telescopically driven to drive the adsorption unit 22 to move, thereby adsorbing the material 10.

[0058] In some embodiments, the telescopic drive unit 21 includes a pneumatic cylinder or an electric cylinder; and / or the adsorption unit 22 includes a magnetic suction head or a suction cup. When the material 10 can be magnetically attracted, the adsorption unit 22 can be a magnetic suction head, and the suction cup can be a vacuum suction cup or a corrugated suction cup, etc.

[0059] In some embodiments, the correction assembly 3 includes at least three clamping jaws 31 and at least three connecting rod members 32, the three connecting rod members 32 are hinged to the telescopic portion 211 and the mounting plate 1, and are distributed along the circumference of the telescopic portion 211, and at least three clamping jaws 31 are connected to the three connecting rod members 32 in a one-to-one correspondence;

[0060] When the telescopic portion 211 is extended or retracted, the connecting rod member 32 can drive the clamping claw 31 to move away from or closer to the telescopic portion 211 in the radial direction, so that the material 10 coincides with the axis of the adsorption unit 22 that adsorbs the material 10 .

[0061] In the present embodiment, when the telescopic portion 211 is extended or retracted, the connecting rod member 32 drives the clamping jaws 31 to move radially away from or closer to the telescopic portion 211. At least three clamping jaws 31 move radially away from or closer to the telescopic portion 211, preferably three clamping jaws 31. Therefore, the connecting rod member 32 of the present embodiment drives the clamping jaws 31 to make materials 10 of different sizes and angles coincide with the axis of the adsorption unit 22 that adsorbs them, ensuring that materials 10 of different sizes and angles are adsorbed at the same position of the suction component 2 at the same angle, which facilitates the precise positioning of the material 10 by the material picking mechanism, eliminates the need for secondary positioning of the material 10 by the material picking mechanism, and improves the material picking efficiency and assembly success rate of the material picking mechanism.

[0062] It should be noted that the axis of the telescopic portion 211 coincides with the axis of the adsorption unit 22, and the structures of the connecting rod members 32 can be the same. When the structures of the connecting rod members 32 are the same, the distances between at least three clamps 31 and the axis of the adsorption unit 22 are always the same.

[0063] Furthermore, the connecting rod member 32 drives the clamping jaw 31 to make the material 10 coincide with the axis of the magnetic suction head or suction cup of the suction unit 22 that adsorbs the material 10.

[0064] In some embodiments, the link member 32 includes a first link 321, a second link 322, and a third link 323, one end of the first link 321, one end of the second link 322, and one end of the clamp 31 are coaxially hinged, the other end of the first link 321 is hinged to the mounting plate 1, the other end of the second link 322 is hinged to the telescopic portion 211, the two ends of the third link 323 are respectively hinged to the telescopic portion 211 and the clamp 31, and the third link 323 is located on the side of the second link 322 away from the mounting plate 1. The cooperation of the first link 321, the second link 322, and the third link 323 of this embodiment with the telescopic drive unit 21 and the clamp 31 realizes that when the telescopic portion 211 is extended and retracted, the link member 32 drives the clamp 31 to move away from or close to the telescopic portion 211 in the radial direction.

[0065] In some embodiments, at least three connecting rod members 32 are evenly distributed along the circumference of the telescopic portion 211, so that at least three clamping jaws 31 are evenly distributed along the circumference of the telescopic portion 211, and this structure ensures that the distances between at least three clamping jaws 31 and the axis of the adsorption unit 22 are always the same, so that the three clamping jaws 31 are automatically centered.

[0066] In some embodiments, the connecting rod member 32 also includes a polygonal columnar connecting portion 33 connected between the telescopic portion 211 and the adsorption unit 22, the number of sides of the polygonal columnar connecting portion 33 is consistent with the number of the connecting rod members 32, and the second connecting rods 322 and the third connecting rods 323 of the multiple connecting rod members 32 are hinged to the multiple side walls of the polygonal columnar connecting portion 33 one by one, and the polygonal columnar connecting portion 33 facilitates the assembly of the multiple connecting rod members 32 corresponding thereto.

[0067] In some embodiments, the material taking mechanism further includes a first control valve 4 , which is disposed on the mounting plate 1 and connected to the telescopic driving unit 21 to control the telescopic movement of the telescopic portion 211 .

[0068] In some embodiments, the material taking mechanism further includes a second control valve 5 , which is disposed on the mounting plate 1 and connected to the adsorption unit 22 to control the adsorption of the adsorption unit 22 or release of the material 10 .

[0069] In some embodiments, there are multiple suction components 2 and correction components 3, which are connected one by one, and each correction component 3 is connected to the mounting plate 1. In this embodiment, multiple materials 10 can be sucked simultaneously or alternately through the cooperation between multiple suction components 2 and the correction components 3 connected one by one, thereby improving the suction efficiency.

[0070] At least three clamping jaws 31 have a certain range of contraction, which can be compatible with the clamping of materials 10 with diameters within a certain range of sizes. And automatic correction of the coaxial line is performed.

[0072] The embodiment of the present invention further provides a driving device, which includes a moving mechanism and the material taking mechanism of embodiment 1, wherein the moving mechanism is connected to the mounting plate 1 to drive the mounting plate 1 to move.

[0073] The moving mechanism can be a three-axis or more-axis moving device such as a robot, so as to drive the installation plate 1 to move in up-down, left-right, front-back and other directions.
