[0029] Example:

[0030] like Figure 1 , 2 , 3, and 5, where Figure 1 This is a diagram showing the use state of the suction cup mechanism of the embodiment of the utility model; Figure 2 This is a side view of the suction cup mechanism in use according to an embodiment of the utility model; Figure 3 For the utility model embodiment Figure 2 AA section view, Figure 5 This is a diagram of the suction cup body in use according to an embodiment of the utility model.

[0031] A suction cup mechanism for an ultrasonic gas meter valve comprises a suction cup body 5; the suction cup body 5 is assembled at the bottom of a manipulator, and the suction movement of the valve 1 is realized by the movement of the manipulator. Specifically, the suction cup body 5 comprises a transverse connecting portion 50 and a longitudinal connecting portion 51, and the transverse connecting portion 50 and the longitudinal connecting portion 51 are in an L-shaped structure; a transverse air vent 56 with a horizontal axis is provided in the transverse connecting portion 50, and a grabbing guide groove 52 is formed along its height direction on the longitudinal connecting portion 51, and a guide opening 53 is formed on the side of the grabbing guide groove 52 close to the transverse connecting portion 50, and a positioning mechanism 8 for positioning the valve 1 is formed at the connection between the transverse connecting portion 50 and the longitudinal connecting portion 51; the positioning mechanism 8 is located at the top of the grabbing guide groove 52; a first longitudinal air vent 55 with a vertical axis is provided on the longitudinal connecting portion 51, one end of the first longitudinal air vent 55 is connected to the transverse air vent 56, and the other end of the longitudinal air vent 55 extends into the positioning mechanism 8, and a vacuum tube 57 is connected to the outer side of the transverse air vent 56, and the vacuum tube 57 is connected to a vacuum pump.

[0032] Through the ultrasonic gas meter valve suction cup mechanism of the present embodiment, through the connection of the vacuum pump and the vacuum tube 57, the adsorbed gas is connected to the first longitudinal vent hole 55 through the transverse vent hole 56, and then the valve 1 is adsorbed. At the same time, during the adsorption process, the positioning mechanism 8 is used to position the valve 1, avoiding the shaking of the valve 1 during the adsorption process, thereby affecting the safety of movement. The utility model adsorbs the ultrasonic gas meter valve on the suction cup body, realizes the stability of the valve adsorption assembly, and the positioning is accurate, fast and reliable, and the assembly consistency is good.

[0033] The transverse connecting portion 50 and the longitudinal connecting portion 51 are fixedly connected and integrally formed, thereby improving the structural strength and overall firmness of the entire suction cup body 5 and further ensuring the safety of the valve 1 adsorption.

[0034] like Figure 6-7 As shown, Figure 6 This is a schematic diagram of the structure of the suction cup body of the utility model embodiment; Figure 7It is a bottom view of the suction cup body of an embodiment of the utility model; wherein, the positioning mechanism 8 includes an inner groove 80, a positioning strip 81 is arranged in a ring shape inside the inner groove 80, a positioning groove 82 is formed in the middle of the inner groove 80, and the positioning groove 82 is located in the middle of the positioning strip 81; the first longitudinal vent hole 55 extends and is connected to the positioning groove 82, and a positioning cylinder 10 adapted to the positioning groove 82 is formed on the top of the valve 1, and when the valve 1 is assembled into the grabbing guide groove 52, the positioning cylinder 10 is embedded in the positioning groove 82.

[0035] A plurality of positioning blocks 83 are equidistantly arranged on the outer side of the positioning groove 82 in the circumferential direction, and the plurality of positioning blocks 83 are located in the positioning strip 81, wherein one end of the positioning block 83 is connected to the positioning strip 81, and the other end of the positioning block 83 extends to the end of the positioning groove 82; by setting the positioning blocks 83, a plurality of positioning blocks 83 are assembled in the positioning groove 82, and a second longitudinal air vent 54 is formed on the inner groove 80, and the second longitudinal air vent 54 is located between adjacent positioning blocks 83, and the second longitudinal air vent 54 is arranged parallel to the first longitudinal air vent 55, and the second longitudinal air vent 54 is connected to the transverse air vent 56, and the second longitudinal air vent 54 is used to adsorb the top of the valve 1, and cooperates with the first longitudinal air vent 55 to achieve the safety of the adsorption of the entire valve 1.

[0036] When the top of the valve 1 is adsorbed to the top of the grabbing guide groove 52, the interval between the positioning block 83 and the positioning strip 81 gives the valve 1 a certain adsorption force, and a guide notch 85 is formed in the middle of the positioning block 83. The guide notch 85 and the inner groove 80 are on the same horizontal plane. The setting of the guide notch 85 allows the inner groove 80 located in the positioning strip 81 to form a connected cavity, so that the second longitudinal vent 54 and the first longitudinal vent 55 have a balanced force when adsorbing the valve 1 at the same time, thereby improving the safety of the adsorption of the valve.

[0037] The end of the positioning block 83 and the end of the positioning strip 81 are on the same horizontal plane, so that when the valve 1 is assembled into the grabbing guide groove 52 , the positioning block 83 and the positioning strip 81 both abut against the top of the valve 1 .

[0038] The end of the positioning block 83 close to the positioning groove 82 is in the form of an arc structure 84, and the arc structure 84 gradually expands along the insertion direction of the positioning tube 10; the arc structure 84 is set so that when the valve 1 is adsorbed, the arc structure 84 increases the contact area with the positioning tube 10, which facilitates the positioning tube 10 to be quickly assembled into the positioning groove 82, thereby improving the assembly efficiency between the two, and at the same time, makes the mobile grasping action simple to realize, the positioning is accurate, fast and reliable, and the assembly consistency is good.

[0039] A groove 58 is formed along the length direction on the inner side of the grabbing guide groove 52 of the longitudinal connecting portion 51. Correspondingly, a limiting protrusion 11 is formed on the outer wall of the valve 1. When the valve 1 is adsorbed into the grabbing guide groove 52 by a vacuum pump, the limiting protrusion 11 of the valve 1 is assembled into the groove 58 and moves upward along the groove 58.

[0040] like Figure 4 As shown, Figure 4 Schematic diagram of the valve structure of an embodiment of the utility model; a limiting protrusion 11 is formed on the outer wall of the valve 1, and an inclined surface is formed on the top of the limiting protrusion 11, and the inclined surface increases successively along the insertion direction. The setting of the limiting protrusion 11 cooperates with the groove 58 to play a guiding role. At the same time, it avoids errors when adsorbing the valve 100, thereby ensuring the stability and safety of the suction cup body 5 adsorbing the valve 100.

[0041] A positioning cylinder 10 is provided at the top of the valve 1. When the valve 1 is assembled into the grabbing guide groove 52, the positioning cylinder 10 is embedded in the positioning groove 82, thereby avoiding the overall shaking of the valve 1. At the same time, when the suction cup body 5 and the valve 1 are assembled, the top part of the valve 1 fits against the inner side of the transverse connecting part 50, thereby increasing the contact surface between the valve 1 and the transverse connecting part 50, making the adsorption of the entire valve 1 safer.

[0042] The inner side of the bottom of the grabbing guide groove 52 has a guide slope 59 that gradually expands along the insertion direction of the valve 1; the setting of the guide slope 59 increases the contact area with the valve 1 when the valve 1 is adsorbed, making the mobile grabbing action simple to implement, the positioning accurate, fast and reliable, and the assembly consistency good.
