Description

Technical Field

[0001] The patent of this invention relates to an automatic sorting and stacking device for waste electric meter markers, which is compatible with three-phase, single-phase, and terminal versions of various meter types, avoids interference from external lead seals, and realizes actions such as rapid grasping, angle correction, and accurate stacking. Background Art

[0002] With the innovation of power grid technology and the iteration of meter products, a large number of obsolete meters have appeared. The sorting process of obsolete meters is related to the recycling and utilization of resources. Considering the isolation of toxic and hazardous substances exposed during the operation, automated sorting and disassembly are particularly important. In addition, the differences in versions and meter conditions that appear during the recycling of discarded meters require personnel to identify, sort and stack them for the convenience of subsequent process operations.

[0003] The discarded meters are sealed with lead seals, which are usually set in the upper left corner, right side and right programming cover of the electricity meter, and are usually more common on the right side of the electricity meter. The lead seal material is hard, and the more commonly used hanging rope type lead seal is connected to the electricity meter through copper wire and will be suspended on the side of the electricity meter. On the one hand, it will affect the clamping stability during the clamping and meter retrieval process of the sorting and stacking device. Excessive clamping force will also damage the clamping mechanism, which needs to be avoided. On the other hand, when the electricity meter is placed in the transfer box, the lead seal on the adjacent electricity meter that has been placed will also impact the clamping mechanism, causing damage or misalignment. Therefore, the equipment needs to achieve efficient sorting and stacking, have strong compatibility with various meter types, and be able to avoid lead seals as much as possible.

DETAILED DESCRIPTION

[0022] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] like Figure 1 , Figure 2 As shown, an automatic code meter device for an electric energy meter includes a material conveying device, a three-coordinate mechanical arm, a rotating mechanism and a clamping mechanism, wherein the clamping mechanism is connected to the rotating mechanism, and the rotating mechanism is installed at the end of the three-coordinate mechanical arm; the clamping mechanism includes an electric clamping jaw 6 and an extended clamping jaw 7 respectively installed at the two claw ends of the electric clamping jaw 6; the extended clamping jaw 7 includes a first claw body 701 and a second claw body 702, wherein the first claw body 701 is a single-finger claw structure, and the second claw body 702 is a two-finger claw structure with an avoidance notch in the middle. The single-finger claw structure of the first claw body 701 is to reduce the contact area and avoid the interference of the lead seal as much as possible, and the avoidance notch of the second claw body 702 is to reduce the weight of the structure while maximizing the grasping stability.

[0024] The three-coordinate robot arm includes an X-axis electric slide 1, an X-axis auxiliary support 4, a Y-axis electric slide 2 and a Z-axis guide rod electric cylinder 3. The X-axis electric slide 1 and the X-axis auxiliary support 4 are arranged in parallel, and the two ends of the Y-axis electric slide 2 are respectively slidably connected to the X-axis electric slide 1 and the X-axis auxiliary support 4; the Z-axis guide rod electric cylinder 3 is vertically arranged and slidably connected to the Y-axis electric slide 2.

[0025] like Figure 3 , Figure 4 As shown, the rotating mechanism includes a turntable motor 11, a collector slip ring 12, and a rotating table 5. The two ends of the rotating table 5 are respectively connected to an electric clamp 6 and a Z-axis screw module 3. The collector slip ring 12 is sleeved on the rotating shaft of the rotating table 5, and the electric clamp 6 is connected to the collector slip ring 12 through a circuit.

[0026] The terminal used to grab the electric energy meter is composed of an electric turntable, a multifunctional slip ring, and an electric clamp. Combined with the currently more mature image recognition technology, it can realize the grabbing of the electric energy meter at different angles in the horizontal state; the first claw body and the second claw body adopt different shapes to avoid interference with the external lead seal as much as possible.

[0027] like Figure 5 As shown, the first claw body 701 is provided with a lead seal avoidance mechanism, which includes a positioning ring 1302, a lever 1303 and a swing drive mechanism; the positioning ring 1302 is sleeved on the claw end of the electric clamp 6, the upper end of the lever 1303 and the positioning ring 1302 are hinged and provided with a reset torsion spring, and the swing drive mechanism is used to drive the lever 1303 to swing from a position close to the extended clamp 7 to both sides.

[0028] The swing drive mechanism includes a slide bar 1401, a driving connecting rod 1402, and a mounting plate 1403. A slide bar 1401 is provided on each side of the electric clamp 6. The two ends of the two slide bars 1401 are connected by the mounting plate 1403. The mounting plate 1403 and the two ends of the electric clamp 6 are connected in an up-and-down sliding manner. One end of the driving connecting rod 1402 is connected in a sliding manner to the slide bar 1401, and the other end is hinged to the middle of the lever 1303. When the mounting plate 1403 slides upward, the slide bar 1401 is raised, and the lever 1303 is lifted by the driving connecting rod 1402. The mounting plate 1404 is provided with a lifting mechanism that drives it to slide up and down. The driving connecting rod 1402 is composed of two hinged small connecting rods, which can also play the role of opening the lead seal.

[0029] The electric clamp 6 is a power mechanism for driving the first claw body 701 and the second claw body 702 to move closer and apart. The lever 1303 is synchronized with the first claw body 701 through the positioning collar 1302 to adapt to different width types of electric meters. The linkage structure of the slide bar 1401 and the driving connecting rod 1402 allows the lever 1303 to move synchronously at different positions and still drive the lever 1303 to swing.

[0030] The lifting mechanism includes a trigger rod 1404, the upper end of the trigger rod 1404 is connected to the mounting plate 1403, and the lower end of the trigger rod 1404 extends vertically downward.

[0031] According to the automatic code meter device of claim 4, it is characterized in that a buffer cross bar 1405 is provided at the lower end of the trigger rod 1304.

[0032] like Figure 6 In another embodiment, the lifting mechanism includes an electromagnetic push rod 1406 , which is installed on the side of the electric clamp 6 , and the push rod end of the electromagnetic push rod 1406 is connected to the mounting plate 1403 .

[0033] The first claw body is located on the right side of the electric energy meter 9, which is the side with more lead seals. The first claw body is provided with a lead seal avoidance mechanism, wherein the lever can protect the claw body structure on both sides of the first claw body, and at the same time can swing the lever and drive the connecting rod external lead seal outward to avoid its influence on the grasping of the electric energy meter. This can also reduce the control system's requirements for the accuracy of grasping and positioning, and reduce software costs.

[0034] When placing the electric energy meter into the transfer box 8, the lever and the driving connecting rod are inserted into the gap between the adjacent electric energy meters together with the first claw body. When the electric energy meter is not completely lowered, the lever swings to open the lead seal of the adjacent electric energy meter to prevent the lead seal on the adjacent electric energy meter that has been placed from impacting the clamping mechanism and causing damage or misalignment.
