Description

Technical Field

[0001] This invention relates to the field of waste electricity meter recycling technology, and in particular to an automatic disassembly device and method for electricity meter PCB boards. Background Technology

[0002] As a typical electronic product, electricity meters have a short lifespan and contain a lot of toxic substances. The green disposal of waste electricity meters has received increasing attention, and how to carry out large-scale harmless disposal has become an urgent problem for the power industry to solve.

[0003] Chinese patent CN202223286151.7 discloses an automatic PCB board splitting machine for waste electricity meters, including a base plate. A bracket is fixedly installed on the upper surface of the base plate, and a mounting housing is fixedly installed on the bracket. An X-axis gantry mechanism is provided on the side wall of the mounting housing. The X-axis gantry mechanism includes a lead screw and a servo motor. The servo motor is fixedly installed on the side wall of the mounting housing, and the output end of the servo motor is fixedly connected to the left end of the lead screw. The other end of the lead screw is rotatably connected to the side wall of the mounting housing, and a moving block is threaded onto the lead screw. This automatic PCB board splitting machine for waste electricity meters can automatically split the PCB boards without manual splitting, saving time and labor, and improving splitting efficiency. After disassembly, the PCB boards can be re-stacked in a turnover box, and other disassembled components are transported to a designated recycling area via a conveyor.

[0004] However, this technical solution has certain shortcomings in its use. The bolt mounting holes of the meter casing are usually protected with lead seals. However, lead is a toxic heavy metal. Existing equipment usually uses a high-power motor to drive a milling cutter to mill the lead. However, after milling, some lead fragments will remain on the casing and bolts, which will affect the recycling of the casing, bolts and lead, and also pose a threat to the health of personnel. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing an automatic disassembly device and method for electricity meter PCB boards. This method uses a disassembly line in conjunction with an unsealing mechanism to remove lead seals, thus solving the problem of lead residue.

[0014] The cooling assembly includes: a cooling station mounted on the fine-tuning base plate; a bushing mounted on the top of the outer shaft; a lower liquid ring mounted below the fine-tuning base plate; a lower liquid groove located at the bottom of the lower liquid ring; an injection pipe connected through the lower liquid ring; three sets of lower liquid pipes located inside the outer shaft; a suction pipe connected through the heat-conducting block; and an inner wear-resistant sealing ring located at the bottom of the lower liquid ring.

[0015] The unloading assembly includes: a cylinder b, which is located at the bottom end of the support plate; a slide rail, which is located at the bottom end of the support plate; a gripper, which is located at one end of the output rod of the cylinder b; and a material belt, which is located below the support plate.

[0016] A method for disassembling an automatic PCB board disassembly device for electricity meters includes the following steps:

[0017] Step 1, Loading process: The mechanical gripper unpacks the stacked meter body trays and precisely positions the meter body on the shift fork line; the shift fork line conveys the trays automatically to the next station, where the labels on both sides of the meter body are removed using a high-hardness steel blade on the label cutting device.

[0018] Step 2, Preliminary Milling: The position of the milling ring is adjusted by the motor a on the transverse rail, as well as the longitudinal rail and the vertical seat. The position of the lead seal is automatically found according to the visual coordinate point. The fine-tuning seat plate is moved down by the cylinder a, so that the protruding end of the drive shaft of the motor b enters the outer guide wheel a, and it engages with the groove of the outer guide wheel a to complete the docking. The outer guide wheel a is rotated by the motor b, and the outer shaft is rotated by the connection between the belt and the outer guide wheel b. With the downward movement of the lifting device, the milling ring at the bottom of the outer shaft contacts the surface of the lead seal and opens an annular groove. The operation stops when the positioning rod is inside the lead seal.

[0019] Step 3, Dust Removal and Cooling Process: When the milling ring is aligned, the negative pressure hood will come into contact with the outer periphery of the lead seal. Due to the rebound force of the telescopic rod, it will be in close contact with the outer periphery of the lead seal to ensure the dust removal effect. The lead block debris generated during the milling process will be sucked out through the negative pressure equipment and negative pressure pipe in the negative pressure tank, reducing the safety hazards caused by lead block debris.

[0020] During milling, coolant is injected into the fixed lower liquid ring through the pump and injection pipe inside the cooling station 341. The coolant is then injected into the bushing that rotates with the outer shaft through the lower liquid groove of the lower liquid ring, and then injected into the heat-conducting block through multiple sets of lower liquid pipes to cool the contact area between the milling ring and the lead seal block. The coolant in the heat-conducting block is pumped back through the pump and extraction pipe to achieve circulating cooling of the coolant during the milling operation, so as to prevent the lead from melting and adhering to the tool and affecting subsequent use.

[0021] Step 4, Peeling Process: After milling, the positioning rod will be placed in the groove milled out of the lead seal block. Through the lifting structure, the protruding end of the drive shaft of motor b enters the inner guide wheel a, so that it engages with the slot of the inner guide wheel a to complete the docking. Motor b drives the inner guide wheel a to rotate. Through the connection between the belt and the inner guide wheel b, the inner shaft rotates slightly. The inner shaft drives the gear ring to rotate. The gears on the three sets of cams mesh with the gear ring, so that the three sets of cams can rotate synchronously. The protruding end of the cam contacts the contact block on the positioning rod and moves outward against the spring force on the seat ring. During the extension process, the power ring on the positioning rod will contact the coil ring on the sleeve, so that the circuit is connected. The coil ring will supply power to the induction coil through the wire. When the current passes through, it will quickly heat the positioning rod. The heat will soften the lead seal block locally. With the rotation and pressure of the inner shaft, the three sets of positioning rods can be quickly inserted into the lead seal block from three directions through the pointed cone to complete the fixation of the lead seal block.

[0022] During the milling operation, some of the debris is squeezed and enters the collection chamber through the collection groove at one end of the sleeve. When the positioning rod is heated, the lead block debris will melt first. After the positioning rod is inserted to the limit depth position, the coil ring is squeezed by the connecting rod and moves to the tail end of the collection chamber. This allows the molten lead to be squeezed from multiple sets of extrusion grooves onto the positioning rod. The extrusion grooves are located on the rod groove of the positioning rod and flow along multiple sets of grooves, increasing the contact surface. After the insertion is completed and the lead cools down, the lead solidifies, causing a lead seal between the positioning rod and the lead block. This greatly improves the connection effect between the positioning rod and the lead block, and avoids excessive peeling pressure that could cause it to fall off. Finally, the lead seal is peeled off by the lifting structure and the clamping device that limits and clamps the meter body.

[0023] Step 5, Collection Process: The stripped lead blocks are removed by cylinder b and grippers and placed on the conveyor belt. The conveyor belt transports the lead blocks to ton bags for collection.

[0024] Step Six, Subsequent Disassembly Process: The intelligent screw removal device uses a three-axis robot to automatically locate the screws based on visual coordinates. An intelligent screwdriver automatically unlocks the screws. A servo motor, in conjunction with a mechanical clamp, separates the upper and lower covers of the meter body to different production lines. A servo-driven automatic screwdriver is used to remove the large screws inside the junction box. For different meter bodies, industrial vision is used to identify and remove the circuit board connections. The disassembled circuit board is separated from the lower casing, and transported to a manual station via a conveyor belt. The lower casing is flipped and positioned on a shift fork line, where the embedded screws and hanging plate are removed by an embedded screw removal device. The lower casing is then transported via a conveyor belt. The circuit board and junction box are manually separated from the ton bag. The junction box is positioned on the platform, and the copper pillar is punched out by the cylinder of the stamping device. After the stamping is completed, the copper pillar and junction box are automatically collected. When the robotic arm is transporting the top cover, it is placed on the mechanism midway, rotated 180 degrees and then transported to the shift fork line. The pallet is automatically transferred to the next station. The communication box removal device uses the mechanism to automatically open the nameplate cover by rotating. The communication box is sucked up by negative pressure. The top cover is removed by the cylinder and suction cup. The observation window is stamped by the cylinder. The top cover is flipped to the shift fork line by the cylinder. The top cover button and embedded nail are punched out. The top cover is separated into the ton bag by the belt conveyor.

[0025] The beneficial effects of this invention are as follows:

[0026] (1) This invention can fully disassemble and recycle electricity meters to a large extent through a series of automated settings on the toggle line a and toggle line b. It is efficient and improves the recycling rate of resources. It is different from traditional semi-automatic or manual recycling and has good market prospects.

[0027] (2) The present invention adjusts the position of the milling ring by using the horizontal rail motor a and the longitudinal rail and vertical seat to automatically find the position of the lead seal according to the visual coordinate point. The cylinder a drives the fine adjustment seat plate to move down, so that the protruding end of the drive shaft of the motor b enters the outer guide wheel a, and it engages with the slot of the outer guide wheel a to complete the docking. The motor b drives the outer guide wheel a to rotate, and the belt connects with the outer guide wheel b to drive the outer shaft to rotate. With the downward movement of the lifting device, the bottom end of the milling ring of the outer shaft contacts the surface of the lead seal and opens an annular groove until the positioning rod is inside the lead seal, and the operation can be stopped, thus creating conditions for subsequent peeling. In addition, the cooling and dust removal structure in the milling operation effectively reduces lead pollution and the harm it causes.

[0028] (3) In this invention, the inner shaft drives the gear ring to rotate, and the gears on the three sets of cams mesh with the gear ring, thereby driving the three sets of cams to rotate synchronously. The protruding end of the cam contacts the contact block on the positioning rod and moves outward against the spring force on the seat ring. During the extension process, the power ring on the positioning rod will contact the coil ring on the sleeve, so that the circuit is connected. The coil ring will supply power to the induction coil through the wire. When the current passes through, it will quickly heat the positioning rod. The heat will cause the lead seal block to soften locally. With the rotation and pressure of the inner shaft, the three sets of positioning rods can be quickly inserted into the lead seal block from three directions through the pointed cone to complete the fixation of the lead seal block. In the milling operation, some of the chips will be squeezed and enter the collection groove at one end of the sleeve. In the collection chamber, the lead fragments melt first when the positioning rod is heated. After the positioning rod is inserted to its maximum depth, the coil ring moves to the tail end of the collection chamber by squeezing the piston ring through the connecting rod. This allows the molten lead to be extruded from multiple sets of extrusion grooves onto the positioning rod. The extrusion grooves are located on the rod groove of the positioning rod and flow along multiple sets of grooves, increasing the contact surface. After insertion is completed and the lead cools, the lead solidifies, creating a lead seal between the positioning rod and the lead block. This greatly improves the connection between the positioning rod and the lead block, preventing excessive peeling pressure from causing it to fall off. Finally, the lifting structure and clamping device limit the clamping of the meter body to peel off the lead seal, thereby reducing the harm caused by lead residue and allowing the lead block to be recycled.

[0068] The negative pressure assembly 33 includes: a negative pressure tank 331, which is mounted on the support plate 308; a negative pressure pipe 332, which is mounted on the negative pressure tank 331; a negative pressure cover 333, which is mounted at the bottom end of the negative pressure pipe 332; an inner slip ring 334, which is mounted at the center of the negative pressure cover 333; and two sets of telescopic rods 335, which are mounted at the top of the negative pressure cover 333.

[0069] In this embodiment, the negative pressure cover 333 can contact the outer periphery of the lead seal. Due to the rebound force of the telescopic rod 335, it is in close contact with the outer periphery of the lead seal to ensure the dust suction effect. The lead block debris generated during the milling process is sucked out by the negative pressure equipment in the negative pressure tank 331 and the negative pressure pipe 332, reducing the safety hazards caused by the lead block debris.

[0070] The cooling assembly 34 includes: a cooling station 341, which is mounted on the fine-tuning base plate 306; a bushing 342, which is mounted on the top of the outer shaft 314; a lower liquid ring 343, which is mounted below the fine-tuning base plate 306; a lower liquid groove 344, which is located at the bottom of the lower liquid ring 343; an injection pipe 345, which is connected through the lower liquid ring 343; three sets of lower liquid pipes 346, which are located inside the outer shaft 314; a suction pipe 347, which is connected through the heat-conducting block 3142; and an inner wear-resistant sealing ring 348, which is located at the bottom of the lower liquid ring 343.

[0071] In this embodiment, coolant is injected into the fixed lower liquid ring 343 through the pump and injection pipe 345 in the cooling station 341. The coolant is then injected into the bushing 342 that rotates with the outer shaft 314 through the lower liquid groove 344 of the lower liquid ring 343. The coolant is then injected into the heat-conducting block 3142 through multiple sets of lower liquid pipes 346 to cool the contact area between the milling ring 3143 and the lead seal block. The coolant in the heat-conducting block 3142 is then pumped back through the pump and extraction pipe 347 to achieve circulating cooling of the coolant during milling operations, preventing lead from melting and adhering to the tool and affecting subsequent use.

[0072] The unloading assembly 35 includes: a cylinder b351, which is located at the bottom of the support plate 308; a slide rail 352, which is located at the bottom of the support plate 308; a gripper 353, which is located at one end of the output rod of the cylinder b351; and a material belt 354, which is located below the support plate 308.

[0073] In this embodiment, the stripped lead blocks are removed by cylinder b351 and gripper 353 and placed on conveyor belt 354. The conveyor belt 354 then transports the lead blocks to a ton bag for collection.

[0074] Example 2: Figures 1-5 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0075] The dismantling line 1 includes a stacking section 11, which is equipped with a stacking device 111 and a mechanical gripper 112. A toggle line a12 is provided on one side of the stacking section 11. An unsealing section 13 and a disassembly section 14 are provided on the toggle line a12. A processing section 15 is provided on one side of the toggle line a12. The unsealing section 13 includes: a label cutting device 131, which is located on the toggle line a12; an intelligent screw removal device 132, which is located on the toggle line a12; a mechanical clamp 133, which is located on one side of the intelligent screw removal device 132; a transfer device 134, which is located on one side of the mechanical clamp 133; and a servo-driven automatic screw gun 135, which is a servo-driven automatic screw gun. The screwdriver 135 is mounted on the shift fork line a12; the separation device 136 is mounted on one side of the servo belt automatic screwdriver 135; the disassembly unit 14 includes: a circuit board disassembly device 141 mounted on the shift fork line a12; a belt line 142 mounted on one side of the circuit board disassembly device 141; a rivet removal device 143 mounted on one side of the circuit board disassembly device 141; and a stamping device 144 mounted on one side of the rivet removal device 143; the processing unit 15 includes: a shift fork line b151 mounted on one side of the shift fork line a12; and a communication box removal device 152 mounted on the shift fork line b151.

[0076] The meter body 2 includes a lower shell 201 located on the disassembly line 1, an upper shell 202 located on the lower shell 201, a lead seal structure 203 located in the threaded hole of the upper shell 202, and a bolt 204 connected to the threaded hole of the upper shell 202.

[0077] In this embodiment, through a series of automated settings on the toggle line a12 and toggle line b151, the electricity meter can be disassembled and recycled to a large extent, which is efficient and improves the recycling rate of resources. It is different from traditional semi-automatic or manual recycling and has good market prospects.

[0078] Example 3: Figures 1-28 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0079] A method for disassembling an automatic PCB board disassembly device for electricity meters includes the following steps:

[0080] Step 1, feeding process: The mechanical gripper 112 unpacks the stacked meter body 2 tray and accurately positions the meter body 2 onto the shift fork line; the shift fork line conveys the tray automatically to the next station, and the high-hardness steel knife on the label cutting device 131 cuts off the labels on both sides of the meter body 2.

[0081] Step 2, Preliminary Milling Process: The position of the milling ring 3143 is adjusted by the motor a302 on the transverse rail 301, as well as the longitudinal rail 303 and the vertical seat 304. The position of the lead seal is automatically found according to the visual coordinate point. The fine adjustment seat plate 306 is moved down by the cylinder a305, so that the protrusion 3134 end of the drive shaft 312 of the motor b311 enters the outer guide wheel a3131, and it engages with the slot 3133 of the outer guide wheel a3131 to complete the docking. The motor b311 drives the outer guide wheel a3131 to rotate. The belt connects the outer guide wheel b3144 to drive the outer shaft 314 to rotate. With the downward movement of the lifting device, the milling ring 3143 at the bottom of the outer shaft 314 contacts the surface of the lead seal and opens an annular groove. The operation stops when the positioning rod 325 is inside the lead seal.

[0082] Step 3, Dust Removal and Cooling Process: When the milling ring 3143 is aligned, the negative pressure cover 333 will come into contact with the outer periphery of the lead seal. Due to the rebound force of the telescopic rod 335, it will be in close contact with the outer periphery of the lead seal to ensure the dust removal effect. The lead block debris generated during the milling process will be sucked out through the negative pressure equipment in the negative pressure tank 331 and the negative pressure pipe 332, reducing the safety hazards caused by the lead block debris.

[0083] During milling, coolant is injected into the fixed lower liquid ring 343 through the pump and injection pipe 345 in the cooling station 341. The coolant is then injected into the bushing 342 that rotates with the outer shaft 314 through the lower liquid groove 344 of the lower liquid ring 343. The coolant is then injected into the heat-conducting block 3142 through multiple sets of lower liquid pipes 346 to cool the contact area between the milling ring 3143 and the lead seal block. The coolant in the heat-conducting block 3142 is then pumped back through the pump and extraction pipe 347 to achieve circulating cooling of the coolant during milling operations and prevent lead from melting and adhering to the tool, which would affect subsequent use.

[0084] Step 4, Peeling Process: After milling, the positioning rod 325 will be positioned in the groove milled by the lead seal block. Through the lifting structure, the protrusion 3134 end of the drive shaft 312 of the motor b311 enters the inner guide wheel a3132, engaging with the slot 3133 of the inner guide wheel a3132. The motor b311 drives the inner guide wheel a3132 to rotate, and the belt connecting to the inner guide wheel b3151 causes the inner shaft 315 to rotate slightly. The inner shaft 315 drives the gear ring 321 to rotate. The gears 323 on the three sets of cams 322 mesh with the gear ring 321, thus driving the three sets of cams 322 to rotate synchronously. Its protrusion... The end contacts the contact block 3251 on the positioning rod 325 and moves outward against the rebound force of the spring 3242 on the seat ring 3241. During the extension process, the power ring 3255 on the positioning rod 325 will contact the coil ring 3263 on the sleeve 326, so that the circuit is connected. The coil ring 3257 will supply power to the induction coil 3262 through the wire 3256. When the current passes through, it will quickly heat the positioning rod 325. The heat will soften the lead seal block locally. With the rotation and pressure of the inner shaft 315, the three sets of positioning rods 325 can be quickly inserted into the lead seal block from three directions through the pointed cone 3252 to complete the fixation of the lead seal block.

[0085] During the milling operation, some of the debris is squeezed and enters the collection chamber 3267 through the collection groove 328 at one end of the sleeve 326. When the positioning rod 325 is heated, the lead block debris will melt first. After the positioning rod 325 is inserted to the limit depth position, the coil ring 3263 is squeezed by the connecting rod 3265 and moves to the tail end of the collection chamber 3267. Thus, the molten lead can be squeezed from multiple sets of extrusion grooves 329 onto the positioning rod 325. The extrusion grooves 329 are located on the rod groove 3253 of the positioning rod 325 and flow along the multiple sets of grooves 3254 to increase the contact surface. Thus, after the insertion is completed and the lead cools down, the lead solidifies, causing a lead seal between the positioning rod 325 and the lead block. This greatly improves the connection effect between the positioning rod 325 and the lead block, and avoids excessive peeling pressure that may cause it to fall off. Finally, the lead seal block is peeled off by the lifting structure and the clamping device 307 limiting the clamping of the meter body 2.

[0086] Step 5, Collection Process: The stripped lead blocks are removed by cylinder b351 and gripper 353 and placed on conveyor belt 354. The lead blocks are then transported to ton bags for collection via conveyor belt 354.

[0087] Step Six, Subsequent Disassembly Process: The three-axis robot on the intelligent screw removal device 132 automatically locates the screws based on visual coordinates, and the intelligent screwdriver automatically unlocks the screws. A servo motor, in conjunction with a mechanical clamp 133, separates the upper and lower covers of the meter body 2 to different production lines. A servo-driven automatic screwdriver 135 is used to remove the large screws inside the junction box. For different meter bodies 2, the circuit board connection method is identified using industrial vision and then removed. The disassembled circuit board is separated from the lower shell 201, and the circuit board is transported to the manual station via a belt conveyor 142. The lower shell 201 is flipped and positioned on the shift fork line, and the embedded screws and hanging plate are removed by the embedded screw removal device 143. The lower shell 201 is then... 1. The circuit board is transported to the ton bag via conveyor belt 142. The circuit board and junction box are separated manually. The junction box is positioned on the platform. The copper pillar is punched out by the cylinder on the stamping device 144. After the stamping is completed, the copper pillar and junction box are automatically collected. When the robotic arm is transporting the top cover, it is placed on the mechanism midway. After rotating 180 degrees, it is transported to the shift fork line. The pallet is automatically transferred to the next station. The communication box removal device 152 automatically opens the nameplate cover by rotating the mechanism. The communication box is sucked up by negative pressure. The top cover is removed by the cylinder and suction cup. The observation window is stamped by the cylinder. The top cover is flipped to the shift fork line by the cylinder. The top cover button and embedded nail are punched out. The top cover is separated to the ton bag via conveyor belt 142.
