Principle of embodiment:
the electric energy meter is conveyed by the feeding conveyor belt 2, then the conveying and pressing mechanism conveys the electric energy meter to the electric energy meter detection device from the feeding conveyor belt 2 for detection, the conveying and pressing mechanism presses the electric energy meter 1 on the electric energy meter detection device during detection, and the electric energy meter detection device is mature in the prior art and does not expand. After the detection is finished, the carrying and pressing mechanism carries the electric energy meter 1 to the feeding conveyor belt 2 again, the feeding conveyor belt 2 runs, the electric energy meter 1 is conveyed to the circular arc transition conveying mechanism and is conveyed to the slide 4 through the circular arc transition conveying mechanism, then the electric energy meter on the slide 4 is carried to the discharging conveyor belt 5 through the carrying mechanism, and the electric energy meter is conveyed to the next process through the discharging conveyor belt 5.
The operation principle of the conveying and pressing mechanism is as follows:
referring to fig. 5, the first stopper 18 is located at the bottom of the elongated slot 22, the electric cylinder 11 is extended, the support plate 12 is lowered, then the press plate 15 is pressed on the electric energy meter on the feeding conveyor 2, the downward pressing spring 21 is shortened, the first stopper 18 slides out of the elongated slot 22 upwards, the elastic element 26 is extended, the clamping plate 43 is folded and clamps the electric energy meter 1, the driving spring 28 is shortened, and the second stopper 20 abuts against the lower inclined surface 24, see fig. 6 and 8.
As the support plate 12 continues to move downward, the downward-pressing spring 21 further shortens, the second stopper 20 slides along the lower inclined surface 24, the downward-pressing shaft 14 stops rotating after rotating for an angle, at this time, the second stopper 20 abuts against the stop surface 25, and the lower part of the first stopper 18 corresponds to the upper inclined surface 19, see fig. 7 and 9.
The support plate 12 then runs upwards, the lower compression spring 21 is extended and the first stop 18 abuts against the upper ramp 19, see fig. 10 and 12.
As the support plate 12 further moves upward, the first stopper 18 slides along the upper slope 19, the pressing shaft 14 rotates by an angle, then the first stopper 18 is embedded into the adjacent short groove 23, when the first stopper 18 reaches the bottom of the short groove 23, the extension of the pressing spring 21 stops, at this time, the clamping plate 43 clamps the electric energy meter, and the electric energy meter and the feeding conveyor 2 are disengaged, see fig. 11 and 13.
Then the servo module 10 operates to convey the electric energy meter to the position above the electric energy meter detection device 3.
Then, the electric energy meter needs to be pressed on the electric energy meter detection device 3 for detection, and the process is as follows:
under the action of the electric cylinder 11, the electric energy meter moves downwards, when the electric energy meter 1 abuts against the electric energy meter detection device, the support plate 12 continues to move downwards, the lower pressing spring 21 shortens, the second limit block 20 abuts against the lower inclined surface 24, and the first limit block 18 slides out of the short groove 23, as shown in fig. 14 and 16.
The support plate 12 continues to move downward and the second stopper 20 slides along the lower slope 24 until the second stopper 20 abuts on the stop surface 25, during which the pressing shaft 14 rotates by an angle. The lower side of the first stopper 18 is aligned with the other upper inclined surface 19. See fig. 15 and 17.
The support plate 12 is then raised and the first stop 18 moves downwards and then abuts against the upper ramp 19. See fig. 18 and 19.
Then the support plate 12 moves upward for a certain distance, at this time, the pressing spring 21 extends for a certain distance, the first limit block 18 slides downward along the upper inclined surface 19, the first limit block 18 is scribed into the adjacent long groove 22, the pressing shaft 14 rotates for an angle, attention needs to be paid, at this time, because the electric energy meter 1 needs to be pressed on the electric energy meter detection device 3, when the first limit block 18 just slides into the upper end of the long groove 22, the support plate 12 stops moving upward, and the state is kept for detection, see fig. 20, because the pressing spring 21 is in a contracted state at this time, the pressing plate 15 presses the electric energy meter 1 on the electric energy meter detection device 3, and at this time, the clamping plate 43 clamps the electric energy meter 1 to play a good limiting role.
After the detection is finished, the supporting plate 12 moves downwards and then moves upwards to clamp the electric energy meter 1, and the process that the electric energy meter 1 is clamped from the feeding conveyor belt 2 by the conveying and pressing mechanism is referred to.
The servo module 10 is then operated to transport the electric energy meter 1 above the feeding conveyor 2, and then the support plate 12 is moved first downward and then upward, which refers to the process of pressing the electric energy meter 1 against the electric energy meter detection device 3, except that after the support plate 12 is finally moved upward, the first stopper 18 reaches the bottom of the elongated slot 22, the elastic element 26 is shortened, the driving spring 28 is extended, and the clamping plate 43 releases the electric energy meter 1.
The operation principle of the arc transition conveying mechanism is as follows:
the motor drives the disc 39 to rotate at a constant speed to drive the pushing electric cylinder 40 to rotate at a constant speed, when the pushing electric cylinder 40 moves to the position below the pushing sliding groove 38, the pushing electric cylinder 40 operates, the output shaft 41 extends upwards and enters the pushing sliding groove 38, along with the operation of the motor, when the output shaft 41 moves from one end of the pushing sliding groove 38 to the other end, the pushing electric cylinder 40 operates, the output shaft 41 moves downwards to leave the pushing sliding groove 38, and the electric energy meter 1 can be pushed to the sliding way 4 by the output shaft 41 continuously in the process.
When the electric energy meter 1 is pushed into the end of the slide rail 36 under the action of the feeding conveyor 2, the electric energy meter is pushed onto the slide way 4 by the output shaft 41 penetrating through the slide rail 36.
The operation principle of the conveying mechanism is as follows:
the elevating system moves, the manipulator 7 is close to the electric energy meter 1 on the slideway 4, the manipulator 7 clamps the electric energy meter 1, then the elevating system moves, the lifting beam 42 moves upwards, the transmission belt 9 moves, the supporting beam 6 moves on the truss 8, when the manipulator 7 moves to the upper part of the discharging conveyor belt 5, the elevating system moves, and the manipulator 7 places the electric energy meter 1 on the discharging conveyor belt 5.
