Description

Technical Field

[0001] This invention patent relates to an automatic sorting and stacking device for waste power meters, which is compatible with three-phase, single-phase and terminal versions of meters, avoids interference from external lead seals, and realizes actions such as rapid grabbing, angle correction and accurate stacking. Background Technology

[0002] With the innovation of power grid technology and the iteration of metering instruments, a large number of obsolete meters have emerged. The sorting process of obsolete meters is crucial for resource recycling and utilization. Considering the isolation of toxic and hazardous substances exposed during the process, automated sorting and dismantling is particularly important. Furthermore, differences in version and condition of obsolete meters during recycling require manual identification and sorting to facilitate subsequent processing.

[0003] Discarded meters often bear lead seals, typically located on the upper left corner, right side, and right programming cover of the meter, with the right side being more common. These seals are made of a hard material, and the more common type, the lanyard-style seal, is connected to the meter via copper wire and suspends on the side. This can affect the stability of the clamping mechanism during sorting and stacking, and excessive clamping force can damage the mechanism, requiring careful avoidance. Furthermore, when placing meters into the transfer box, the lead seals on adjacent meters can impact the clamping mechanism, causing damage or misalignment. Therefore, the equipment needs to achieve efficient sorting and stacking, strong compatibility with various meter types, and the ability to avoid the lead seals as much as possible. Summary of the Invention

[0004] The present invention aims to overcome the above-mentioned shortcomings in the prior art and provides an automatic meter reading device for electricity meters, wherein the gripper mechanism is designed with a lead seal avoidance mechanism to minimize the impact of the external lead seal on the gripping and placement of the electricity meter.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: This application discloses an automatic meter reading device for electricity meters, comprising a material conveying device, a three-coordinate robotic arm, a rotating mechanism, and a gripper mechanism. The gripper mechanism is connected to the rotating mechanism, which is installed at the end of the three-coordinate robotic arm. The gripper mechanism includes an electric gripper and an extension gripper, which are respectively installed at the two ends of the electric gripper. The extension gripper includes a first gripper body and a second gripper body. The first gripper body is a single-finger gripper structure, and the second gripper body is a two-finger gripper structure with a clearance notch in the middle.

[0006] Preferably, the first claw body is provided with a lead seal avoidance mechanism, which includes a positioning collar, a lever, and a swing drive mechanism; the positioning collar is sleeved on the claw end of the electric gripper, the upper end of the lever is hinged to the positioning collar, and the swing drive mechanism is used to drive the lever to swing from the position close to the extended gripper to both sides.

[0007] Preferably, the swing drive mechanism includes a slide rod, a drive link, and a mounting plate. A slide rod is provided on each side of the electric gripper, and the two ends of the two slide rods are connected by the mounting plate. The mounting plate and the two ends of the electric gripper are slidably connected vertically. One end of the drive link is slidably connected to the slide rod, and the other end is hinged to the middle of the lever. When the mounting plate slides upward, it raises the slide rod and lifts the lever through the drive link. The mounting plate is provided with a lifting mechanism to drive its vertical sliding.

[0008] Preferably, the lifting mechanism includes a trigger rod, the upper end of which is connected to a mounting plate, and the lower end of which extends vertically downward.

[0009] Preferably, the lower end of the trigger rod is provided with a buffer crossbar.

[0010] Preferably, the lifting mechanism includes an electromagnetic push rod, which is mounted on the side of the electric gripper, and the push rod end of the electromagnetic push rod is connected to a mounting plate.

[0011] Preferably, the three-coordinate robotic arm includes an X-axis electric slide rail, an X-axis auxiliary support, a Y-axis electric slide rail, and a Z-axis guide rod electric cylinder.

The two ends of the turntable are respectively connected to an electric gripper and a Z-axis guide rod electric cylinder. The slip ring is sleeved on the rotating shaft of the turntable, and the electric gripper is connected to the slip ring through an electrical circuit.

[0013] Therefore, the present invention has the following beneficial effects: (1) The terminal for grasping the electricity meter consists of an electric turntable, a multi-functional slip ring, and an electric gripper. With the currently mature image recognition technology, it can grasp the electricity meter at different angles in a horizontal state; (2) The first claw and the second claw adopt different shapes to avoid interference from the external lead seal as much as possible; (3) The first claw is located on the right side of the electricity meter, which is the side with more lead seals.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1 , Figure 2 As shown, an automatic meter reading device for electricity includes a material conveying device, a three-coordinate robotic arm, a rotating mechanism, and a gripper mechanism. The gripper mechanism is connected to the rotating mechanism, which is installed at the end of the three-coordinate robotic arm. The gripper mechanism includes an electric gripper 6 and an extended gripper 7, respectively installed at the two ends of the electric gripper 6. The extended gripper 7 includes a first gripper body 701 and a second gripper body 702. The first gripper body 701 is a single-finger gripper structure, and the second gripper body 702 is a two-finger gripper structure with a clearance notch in the middle. The single-finger gripper structure of the first gripper body 701 is to reduce the contact area and avoid interference from the lead seal as much as possible. The clearance notch of the second gripper body 702 is to reduce the weight of the structure while maximizing gripping stability.

[0023] The three-coordinate robotic arm includes an X-axis electric slide rail 1, an X-axis auxiliary support 4, a Y-axis electric slide rail 2, and a Z-axis guide rod electric cylinder 3. The X-axis electric slide rail 1 and the X-axis auxiliary support 4 are arranged in parallel. The two ends of the Y-axis electric slide rail 2 are slidably connected to the X-axis electric slide rail 1 and the X-axis auxiliary support 4, respectively. The Z-axis guide rod electric cylinder 3 is arranged vertically and slidably connected to the Y-axis electric slide rail 2.

[0024] like Figure 3 , Figure 4 As shown, the rotating mechanism includes a turntable motor 11, a slip ring 12, and a turntable 5. The two ends of the turntable 5 are respectively connected to an electric gripper 6 and a Z-axis guide rod electric cylinder 3. The slip ring 12 is sleeved on the rotating shaft of the turntable 5, and the electric gripper 6 is connected to the slip ring 12 through a circuit.

[0025] The terminal for grabbing electricity meters consists of an electric turntable, a multi-functional slip ring, and an electric gripper. With the help of the relatively mature image recognition technology, it can grab electricity meters at different angles in a horizontal state. The first and second grippers have different shapes to avoid interference from the external lead seal as much as possible.

[0026] like Figure 5 As shown, the first claw body 701 is provided with a lead seal avoidance mechanism, which includes a positioning collar 1302, a lever 1303 and a swing drive mechanism; the positioning collar 1302 is sleeved on the claw end of the electric gripper 6, the upper end of the lever 1303 is hinged to the positioning collar 1302 and is provided with a return torsion spring, and the swing drive mechanism is used to drive the lever 1303 to swing from the position close to the extended gripper 7 to both sides.

[0027] The swing drive mechanism includes a slide rod 1401, a drive link 1402, and a mounting plate 1403. A slide rod 1401 is installed on each side of the electric gripper 6, and the two ends of the two slide rods 1401 are connected by the mounting plate 1403. The mounting plate 1403 and the two ends of the electric gripper 6 are slidably connected vertically. One end of the drive link 1402 is slidably connected to the slide rod 1401, and the other end is hinged to the middle of the lever 1303. When the mounting plate 1403 slides upward, it raises the slide rod 1401 and lifts the lever 1303 via the drive link 1402. The mounting plate 1404 is equipped with a lifting mechanism to drive its vertical sliding. The drive link 1402 consists of two hinged small connecting rods and can also be used to open the lead seal.

[0028] The electric gripper 6 is a power mechanism used to drive the first gripper body 701 and the second gripper body 702 to approach and separate. The lever 1303 moves synchronously with the first gripper body 701 through the positioning collar 1302 to accommodate meters of different widths. The linkage structure between the slide bar 1401 and the drive linkage 1402 allows the lever 1303 to swing even when it moves at different synchronous positions.

[0029] The lifting mechanism includes a trigger rod 1404, the upper end of which is connected to the mounting plate 1403, and the lower end of the trigger rod 1404 extends vertically downward.

[0030] The lower end of the trigger rod 1304 is provided with a buffer crossbar 1405.

[0031] like Figure 6 In another embodiment, the lifting mechanism includes an electromagnetic push rod 1406, which is mounted on the side of the electric gripper 6, and the push rod end of the electromagnetic push rod 1406 is connected to the mounting plate 1403.

[0032] The first claw body, located on the right side of the energy meter 9, is the side with the most lead seals. The first claw body is equipped with a lead seal avoidance mechanism. A lever protects the claw body structure on both sides, and simultaneously swings the lever and drive linkage outwards to the external lead seals, preventing them from affecting the grasping of the energy meter. This also reduces the accuracy requirements of the control system for grasping and positioning, and lowers software costs.

[0033] When the electricity meter is placed into the transfer box 8, the lever and drive linkage, together with the first claw body, are inserted into the gap of the adjacent electricity meter. Before the electricity meter is fully placed, the lever swings to open the lead seal of the adjacent electricity meter, so as to prevent the lead seal on the already placed adjacent electricity meter from impacting the claw mechanism and causing damage or misalignment.
