Description

Technical Field

[0001] The present invention relates to the technical field of charging pile recycling, and in particular to automatic disassembly equipment and method for charging piles. Background Art

[0002] Driven by the new energy vehicle industry, charging piles have become indispensable supporting facilities and are being widely installed. According to statistics, by 2020, the number of new energy vehicles in my country will reach 6.1 million, and the number of supporting charging piles will reach 1.743 million. Charging piles generally have a lifespan of 5 to 10 years. Due to inconsistencies in charging protocols and charging interfaces, charging piles installed earlier have been gradually withdrawn from the market and urgently need to be scrapped and dismantled. As time goes by, charging piles installed in recent years will face a surge in scrapping in 3 to 5 years. Standardized dismantling of scrapped charging piles will become an indispensable part of the sustainable development of the entire new energy vehicle industry chain.

[0003] Traditionally, charging piles have been considered general electronic waste, and their dismantling has received little public attention. However, charging piles contain a large number of circuit boards, which are classified as hazardous waste according to the National List of Hazardous Wastes, classified as HW49 and coded 900-045-49. Failure to properly dismantle charging piles can cause significant environmental damage.

[0004] Traditionally, charging pile disassembly involves manually cutting the outer shell with a handheld cutter, then using scissors and electric / pneumatic screw removal tools to separate the modules. This traditional disassembly method, which relies on manual handheld cutting, poses significant safety risks and is prone to injury. Furthermore, manual disassembly is inefficient and cannot meet the needs of disassembling large quantities of scrapped charging piles, resulting in significant limitations.

[0005] The structure of existing charging piles is as follows Figure 1 As shown, it consists of a power module 1110, a power control module 1120, a display screen 1130, a billing control unit 1140, a relay module 1150, a charging gun meter module 1160, wires 1170, left and right side doors 1180, and a top and bottom lock 1190. The left and right side doors of the charging pile 1100 are provided with top and bottom locks, and the power module is provided with a pull ring 1111 for easy extraction. The power module is inserted into the charging pile box and fixed by screws on both sides. The power control module and the relay are installed symmetrically front to back. The charging gun meter module is also installed symmetrically front to back, that is, it is installed in the same position of the iron sheet of the charging box, but part of it is in the front and part of it is in the back. The iron sheet can be cut and taken out together. The billing control unit is fixed to the bracket by screws. The wires are connected to each module. White rings 1171 are provided at the ends of the wire cutting connections, which provide good positioning points for wire cutting. The wires are neatly arranged in the form of wire harnesses on the charging pile box. Figure 1 Only two wires are drawn as representatives. Summary of the Invention

The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0053] Reference Figure 4 , an automatic disassembly equipment for charging piles, comprising:

[0054] Disassembly station 100;

[0055] The rotating platform 200 includes a rotating disk 220 for loading the charging pile. The rotating platform 200 of the charging pile automatic disassembly equipment can move on the disassembly platform 100 of the charging pile automatic disassembly equipment. Figure 4 The direction of movement in is from right to left;

[0056] A plurality of robotic arms 300 are sequentially arranged on the sides of a disassembly platform (100) of the charging pile automated disassembly equipment;

[0057] Along the disassembly platform 100 of the automatic disassembly equipment for charging piles, there are sequentially provided a laser cutting device 400, a grasping device 500, a wire cutting device 600, an electromagnetic suction device 700, a suction cup extraction device 800, a ring cutting device 900 and a power module extraction device 1000. The laser cutting device 400, the grasping device 500, the wire cutting device 600, the electromagnetic suction device 700, the suction cup extraction device 800, the ring cutting device 900 and the power module extraction device 1000 of the automatic disassembly equipment for charging piles are respectively moved in three dimensions by the automatic disassembly equipment mechanical arm 300 of the charging piles.

[0058] The power module extraction device 1000 of the automatic disassembly equipment for charging piles includes a telescopic rod assembly and an extraction bracket 1010 . The telescopic rod assembly and the extraction bracket 1010 form a closed-loop structure, and the closed-loop structure of the automatic disassembly equipment for charging piles is used to buckle the pull ring 1111 of the power module 1110 .

[0059] In this embodiment, the disassembly table 100 is divided into four functional areas. A robotic arm 300 is provided on both sides of the first functional area, which are respectively equipped with a laser cutting device 400 and a grasping device 500. A robotic arm 300 is provided on one side of the second functional area, which is respectively equipped with a wire cutting device 600. A robotic arm 300 is provided on both sides of the third functional area, which are respectively equipped with an electromagnetic suction device 700 and a suction cup extraction device 800. A robotic arm 300 is provided on both sides of the fourth functional area, which are respectively equipped with a ring cutting device 900 and a power module extraction device 1000.

[0060] The specific disassembly method is as follows:

[0061] S1. The transport cart 1200 transports the charging pile 1100 to the disassembly station 100. The transport cart 1200 moves along a preset trajectory under program control and automatically aligns with the disassembly station 100.

[0062] S2. First, enter the first functional area and use the laser cutting device 400 to cut the outer handle of the charging station 1100 and the lock 1190. Then, use the grasping device 500 to open the side door. Then, use the laser cutting device 400 to cut around the installation locations of the display screen 1130, power control module 1120, charging gun meter module 1160, and billing control unit 1140. Finally, cut the connecting hinges of the left and right side doors 1180 in preparation for subsequent extraction.

[0063] S3. Use the wire cutting device 600 to cut and clamp all wires 1170. Both ends of the wires 1170 inside the charging pile 1100 are equipped with white wire ferrules 1170. By identifying the position of the white ferrules 1171, the wire 1170 can be cut to determine the location. The wire cutting device 600 is mounted on the robot arm via the robot arm connector 340. Controlling the movement of the robot arm allows the wire cutting device 600 to reach the designated clamping and cutting position.

[0064] S4. Using the electromagnetic suction device 700 and the suction cup extraction device 800 corresponding to the left and right side doors 1180, the power control module 1120, the charging gun meter module 1160, the billing control unit 1140 and the display 1130;

[0065] S5. Circular cutting device 900 is used to perform a rotary cut on the mounting screws of power module 1110, thereby cutting a circle out of the metal ring on power module 1110 to which the screws are attached. This allows power module 1110 to be extracted without disassembling the screws. This solves the problems of accurate screw positioning during intelligent disassembly and the removability of damaged screws. The power module extraction device 1000 is then used to buckle the pull ring 1111 on power module 1110 and pull it outward to extract power module 1110.

[0066] S6. Finally, the remaining charging pile 1100 shell is transported to the scrap metal recycling site using the transport vehicle 1200.

[0067] In some embodiments, the disassembly station 100 is composed of a guide rail rack, a disassembly platform, and a robotic arm mounting platform. The guide rail rack is installed on the disassembly platform to enable the rotating platform 200 to move along the disassembly platform, and the robotic arm mounting platform is used to fix the robotic arm.

[0068] In some embodiments, the rotating platform 200 is Figure 5 As shown, it includes a movable base 210 and a rotating disk 220. Gears are provided on both sides of the movable base 210, and the movable base 210 moves on the disassembly table 100 through the engagement of the gear rack. The rotating disk 220 is rotatably connected to the top of the movable base 210, and the rotation direction of the rotating disk 220 is controlled by a motor.

[0069] In some embodiments, racks are provided on both sides of the upper surface of the transport trolley 1200 so that the rotating platform 200 can be moved from the transport trolley 1200 to the disassembly platform.

[0070] In some of these embodiments, the robotic arm, such as Figure 6As shown, from bottom to top, it consists of a base 310, a rotating platform 320, an upper arm 330, a connecting member 340, a rotating sleeve 350, a small arm 360, and a gripper connecting mechanism 370. The upper arm 330 is hinged to the rotating platform 320, the rotating sleeve 350 is hinged to the upper arm 330, the two ends of the connecting member 340 are hinged to the upper arm 330 and the rotating sleeve 350, respectively, the rotating sleeve 350 is fixedly connected to the small arm 360, and the small arm 360 is hinged to the gripper connecting mechanism 370. The top of the gripper connecting mechanism 370 is used to connect various actuators, and the three-dimensional spatial movement of each actuator is achieved through the cooperation between these components.

[0071] In some embodiments, the laser cutting device 400 is as follows Figure 7 As shown, the laser cutting device 400 is composed of a nozzle 410, a focusing lens 420, a focus tracking system, and a fiber laser. The nozzle, focusing lens 420, and focus tracking system constitute the cutting blade 950 of the laser cutting device 400, which is responsible for the output of the laser, while the fiber laser is the generator of the laser. The laser cutting device 400 is mounted on a robotic arm. Driven by the robotic arm, the laser cutting device 400 first cuts off the outer handle of the lock 1190, which normally tilts upward due to the spring. The gripping device 500 then grabs the partially tilted handle and rotates it, opening the side door. The laser cutting device 400 then circumscribes the metal sheet surrounding the display screen 1130, power control module 1120, charging gun meter module 1160, and billing control unit 1140. Finally, the connecting hinges of the left and right side doors 1180 are cut, preparing for the extraction of the display screen 1130, power control module 1120 + relay module 1150, charging gun meter module 1160, billing control unit 1140, and left and right side doors 1180. The laser cutting device 400 produces an extremely small laser spot, high energy density, and fast cutting speed, resulting in excellent cutting quality.

[0072] In some embodiments, the gripping device 500 is as follows: Figure 8-9As shown, it includes a fixed frame 510, a lifting frame 520 and a first gripper. The lifting frame 520 can move up and down. The lower end surface of the lifting frame 520 is provided with two or more vertical pull rods 540. The end of the pull rod 540 is provided with a horizontal long through hole 550. The first gripper includes two or more fingers 530. Each finger 530 has a first fixed position 560 and a first movable position 570. The first fixed position 560 is hinged to the fixed frame 510, and the first movable position 570 is connected to the pull rod 540 through the long through hole 550. The up and down movement of the lifting frame 520 can drive each finger 530 to rotate around the first fixed position 560 to realize the opening and closing of the first gripper. Both the first fixed position 560 and the first movable position 570 are cylindrical rotating shafts. The rotating platform 200 first rotates the charging pile 1100 180 degrees after the laser-cut handle of the lock 1190. The robotic arm connector 340 connects the grasping device 500 to the robotic arm. The robotic arm's movable grasping device 500 moves directly in front of the lock 1190's outer handle, which has been partially lifted due to the laser cutting. The lifting frame 520 then moves up and down, allowing the first grasping device to perform an opening and closing grasping action using the first fixed position 560 as the rotation axis. Once the grasping device 500 grasps the lifted outer handle of the lock 1190, the robotic arm rotates to open the lock 1190. Once the left and right side doors are opened, the rotating platform 200 rotates the charging pile 1100 180 degrees to perform the laser cutting of the interior of the charging pile 1100. The grasping device 500 has a simple structure, requires only a single motor to complete the grasping action, and operates with high stability.

[0073] In some embodiments, the grasping device 500 further includes a lead screw 580, on which the lifting frame 520 is mounted. A nut 521 is fixed to the lifting frame 520, threading the lead screw 580 therewith. Rotation of the lead screw 580 drives the lifting frame 520 up and down. A motor is mounted on the main frame and connected to the lead screw 580. The lead screw 580 is provided with a bearing to ensure stable operation of the lead screw 580. The lead screw 580 cooperates with the nut 521, and driven by the motor, the nut 521 is pulled upward. The nut 521 is connected to the lifting frame 520, causing the lifting frame 520 to rise with it. The direction of rotation of the motor can control the lifting and lowering of the lifting frame 520.

[0074] In some embodiments, the wire cutting device 600 is Figure 10-11As shown, it includes a cutting device main frame 610, a second gripper 620, a saw wheel 630, a rotary cutting disk 640 and a movable connecting rod 650. The second gripper 620 includes two gripping rods, each gripping rod has a second fixed position 660 and a second movable position 670. The second fixed position 660 is hinged to the cutting device main frame 610, and the second movable position 670 is hinged to the connecting rod 650. The movement of the connecting rod 650 can drive each gripping rod to rotate around the second fixed position 660 to realize the opening and closing of the second gripper 620. The rotary cutting disk 640 is rotatably connected to the cutting device main frame 610 and is eccentrically connected to the saw wheel 630. White wire 1170 loops are provided at both ends of the connection of the internal wires 1170 of the charging pile 1100. It should be noted that due to the large number of wires inside the charging pile 1100, this embodiment only takes the wires 1170 as an example. By identifying the position of the white ferrule 1171, the cutting of the wire 1170 can be positioned. The wire cutting device 600 is mounted on the robotic arm via the robotic arm connector 340. Controlling the movement of the robotic arm allows the wire cutting device 600 to reach the designated clamping and cutting position. The motor drives the connecting rod 650 to push the second active position 670 on the gripping rod, causing the gripping rod to rotate around the second fixed position 660 as the center point, thereby achieving the gripping of the wire 1170. The saw wheel 630 is then driven by the motor to rotate, and the rotary cutting disk 640 is driven by another motor and driven by a worm gear. The rotation of the rotary cutting disk 640 drives the high-speed rotating saw wheel 630 to cut the wire 1170. After cutting the head and tail of the wire 1170, the wire 1170 can be clamped and removed using the gripper. The wire cutting device 600 combines cutting and gripping functions. After cutting, the wire can be immediately gripped without replacing other actuators, making operation more convenient and efficient.

[0075] In some embodiments, the wire cutting device 600 also includes a push rod 680, which is connected to the connecting rod 650. The push rod 680 is provided with a rack, and the push rod 680 is provided with a push rod 680 sleeve. The push rod 680 sleeve is fixed to the main frame 610 of the cutting device. The gear is driven by the motor, and the gear is engaged with the rack so that the push rod 680 can push the connecting rod 650 forward along the push rod 680 sleeve.

[0076] In some embodiments, the ring cutting device 900 is as follows Figure 12As shown, it includes a rotatable circular cutting head, which includes a front cover 910, a rear cover 920, a double-layer turntable 930, a knob 940 and a number of cutting knives 950 installed in a circular array on the front cover 910, the cutting knives 950 are slidably connected to the front cover 910, the double-layer turntable 930 is installed between the front cover 910 and the rear cover 920, the knob 940 is located on the rear side of the double-layer turntable 930, the front end face of the double-layer turntable 930 is provided with a flat thread and cooperates with the cutting knife thread, and the rear end face of the double-layer turntable 930 is a bevel gear and cooperates with the knob 940. First, the mechanical arm drives the mechanical arm connector 340 to move so that the ring cutting device 900 arrives at the specified position. The motor is the power source for rotary excision. The motor transmits the rotational power to the ring cutting head through the meshing of two bevel gears. The bevel gear on the knob 940 is engaged with the bevel gear on the rear end face of the double-layer turntable 930 to drive the double-layer turntable 930 to rotate. When the double-layer turntable 220 rotates, the flat thread on the front face cooperates with the thread on the cutting knife, so that the cutting knife moves outward or inward along the slide rail on the front cover 910 to achieve the adjustment of the ring cutting radius of the ring cutting head. Therefore, the ring cutting device 900 needs to adjust the ring cutting radius of the ring cutting head according to the model of the power module 1110 connecting screw before work, specifically by rotating the knob 940 to adjust. The ring cutting device 900 can adjust the ring cutting radius, which is more versatile than the traditional fixed ring cutting radius.

[0077] In some embodiments, the power module extraction device 1000 is as follows: Figure 13-15As shown, the telescopic rod 1030 assembly and the extraction bracket 1010 are comprised of a central gear 1020 and two telescopic rods 1030 located on either side of the central gear 1020. The inner sides of the telescopic rods 1030 are racks that mesh with the central gear 1020, while the outer sides are slidably connected to the extraction bracket 1010. The extraction bracket 1010 is bent toward the telescopic rods 1030 at both ends to form a bending structure 1040. Specifically, the bending structure 1040 has a bending angle of 90°. The central gear 1020 drives the two telescopic rods 1030 to move in opposite directions until they contact the bending structure 1040, forming a closed loop structure for engaging the pull ring 1111. After the cutting device 900 cuts the screws connecting the power module 1110, the power module extraction device 1000 moves to the pull ring 1111 in front of the power module 1110 through the mechanical arm. The central gear 1020 is driven to rotate by the motor and the worm gear. The central gear 1020 engages with the rack on the telescopic rod 1030, causing the telescopic rod 1030 to move in the opposite direction until it contacts the bending structure 1040, so that the extraction bracket 1010 and the telescopic rod 1030 form a closed loop structure. At this time, the pull ring 1111 has been buckled into the closed loop. Then, the mechanical arm can be moved to extract the power module 1110. The source module extraction device 1000 can buckle the two pull rings on the power module 1110 at the same time, and only a relatively light telescopic rod can be used to obtain a larger load-bearing capacity, ensuring that the power module 1110 is pulled out horizontally with less movement resistance.

[0078] In some embodiments, the bending structure 1040 is provided with a through hole 1050, and the telescopic rod 1030 can be extended into the through hole 1050. The through hole 1050 can assist the telescopic rod 1030 in bearing force, and also make the closed loop tighter and stronger, preventing the power module 1110 from falling off.

[0079] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the scope of the present invention.
