In a preferred state, the specific working process of the electric energy meter detection system provided by the embodiment of the invention is as follows:
(1): after the electric energy meter 11 to be detected comes from the electric energy meter conveying device, the type of the electric energy meter 11 is identified through the image identification unit, the electric energy meter is grabbed and placed on the corresponding tray 12 through the robot, and the electric energy meter is pushed to the left by a free stroke (figure 3: a figure).
(2): after the electric energy meter is pushed to move through the free stroke, the positioning block 13 is contacted with the right edge of the positioning area at the bottom of the tray 12 (figure 3: two), at the moment, the electric energy meter 11 is crossed with the external connecting posts 10, and the external connecting posts 10 enter the electric energy meter 11 for a distance of L1; the first link 14 extends to a height H.
(3): (FIG. 3: three figures) at this point, the robot continues to push 12 pallets to the left, pushing stroke X (according to actual commissioning).
Meanwhile, the tray 12 drives the positioning block 13 to move leftwards, and the positioning block 13 drives the fixing block 17 to move the fourth connecting rod 18 leftwards. When the fourth link 18 moves to the left, the right end pulls the second link 15 and the third link 16 to move to the left, so that the first link 14 indirectly moves upwards by the travel distance y. The left end pushes the rotating wheel 19 to rotate anticlockwise, so as to drive the fifth connecting rod 20 to move rightwards, the movable plate 7 is driven to move rightwards, the inner core tensioning part 9 moves rightwards, meanwhile, the tension spring 5 is driven to expand, the external connecting column 10 expands outwards through the conical surface, and the external connecting column is further in close contact with the detection position of the electric energy meter 11.
At this time, the tension of the tension spring 5 is not enough to overcome the friction force formed by the gravity of the tray 12 and the resistance of the external connection column 10 which is expanded outwards to be in close contact with the detection position of the electric energy meter 11 through the inner core tension member 9, so that the electric energy meter 11 can be monitored safely.
During the pushing movement, since the positioning block 13 is in contact with the tray 12, the positioning block 13 is driven to move leftwards by pushing the tray 12. After the travel distance X is finished, when the fourth connecting rod 18 moves leftwards, the left-end rotating wheel 19 rotates anticlockwise, the angle included angle formed by the second connecting rod 15 and the third connecting rod 16 becomes smaller, and because the upper end of the second connecting rod 15 is fixed, the whole fourth connecting rod 18 moves upwards for a certain distance (in the process, the fourth connecting rod 18 and the base 2 are always kept in a parallel state).
Drive locating piece 13 certain distance of rebound this moment, leave certain space between locating piece 13 and the base 2, thereby make things convenient for going on of follow-up work, in this process, the bottommost of first inclined plane 24 is higher than the bottommost of second inclined plane 25, consequently when locating piece 13 distance of rebound is greater than A, second inclined plane 25 contacts with first inclined plane 24, locating piece 13 can take place certain rotation simultaneously, consequently, can make tray 12 continue to drive locating piece 13 through two inclined planes of mutual contact and move, along with the continuation motion of moving process, after the motion is accomplished, locating piece 13 distance of rebound is greater than A.
(4): after detection is completed, the robot presses the first connecting rod 14 to move downwards, and in the process, an angle formed by the second connecting rod 15 and the third connecting rod 16 is increased, so that the fourth connecting rod 18 is driven to move rightwards. In the moving process, the fourth connecting rod 18 is always parallel to the base 2, the fourth connecting rod 18 moves obliquely downward, the fourth connecting rod 18 moves downward along the elongated hole 21 under the action of the elongated hole 21, and under the action of the fixing block 17, the fixing block 17 is in a contact state with the sixth connecting rod 23, and the upper end of the sixth connecting rod 23 is hinged to the positioning block 13, so that the positioning block 13 is driven to rotate.
In this process, the lowermost end of the first inclined surface 24 is higher than the lowermost end of the second inclined surface 25, so that the positioning block 13 may rotate, and the first inclined surface 24 is an inclined surface, so that the second inclined surface 25 does not affect the rotation of the positioning block 13, and the first inclined surface 24 allows the positioning block 13 to have a sufficient rotation distance, and if the lower right corner of the positioning block 13 is set to be a right angle, the rotation distance is too small, thereby affecting the normal operation of the device.
In the process of the movement, the position of the tray 12 is ensured to be kept still all the time, and the electric energy meter 11 is kept still if the tray 12 is not moved, so that the external connecting posts 10 can be separated from the electric energy meter 11, and the electric energy meter 11 cannot be damaged.
Meanwhile, the fourth connecting rod 18 drives the rotating wheel 19 to rotate clockwise, so that the fifth connecting rod 20 moves leftwards, the movable plate 7 moves leftwards under the action of the tension spring 5, and the inner core tensioning member 9 is driven to move leftwards, so that the external connecting posts 10 are drawn close to the center.
At this time, in the previous step, the outer connecting post 10 has already moved closer to the center, and at this time, the outer connecting post 10 is separated from contact with the electric energy meter 11, so that the tray 12 can drive the electric energy meter 11 to move without hindrance.
Meanwhile, the fifth connecting rod 20 continues to move leftwards, the movable plate 7 moves leftwards under the action of the tension spring 5, the inner core tensioning member 9 moves leftwards to the initial position, and finally the external connecting column 10 is restored to the initial state.
The robot pulls the tray 12 to the right, and at this time, the positioning block 13 moves to the right due to the tray 12 and falls onto the upper surface of the base 2 again to form sliding contact.
The robot drives the tray 12 to move rightwards to finish the free travel (namely, the state of the figure 3 is recovered), and after the robot stops pulling, the electric energy meter 11 on the tray 12 is grabbed and placed on the production line for subsequent sorting.
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention.
