Description

Technical Field

[0002] With the rapid development of the global new energy vehicle industry, the market demand for new energy charging piles has exploded, and higher requirements have been placed on the production efficiency and assembly accuracy of charging piles. In order to improve production efficiency and quality, some companies have introduced industrial robots to participate in the assembly of charging piles. However, the existing assembly technology based on industrial robots still has many limitations. On the one hand, traditional industrial robots often need to frequently replace fixtures or adjust programs when handling screw assembly of charging piles of different specifications, resulting in long production line switching time, low flexibility, and difficulty in adapting to diverse product needs. On the other hand, during the screw tightening process, there is a lack of effective overload protection mechanism. When encountering abnormal situations such as screw jamming, it is easy to cause damage to the charging pile casing or wear of the screwdriver head, increasing equipment maintenance costs and production losses. In addition, during the screw tightening process, the stability of the charging box is difficult to guarantee, and vibration and displacement will affect the screw tightening quality, resulting in a decrease in the pass rate.

[0014] Compared with the prior art, the advantages and positive effects of the present invention are:

[0015] 1. The present invention proposes an assembly device for new energy charging piles based on industrial robots. After the industrial robot drives the mechanical arm to accurately position itself at the assembly station, the screwdriver head magnetically attracts the screw, and the second motor drives the rotating cylinder to link the slider to achieve preliminary alignment of the screwdriver head with the threaded hole. The sliding seat is adjusted by the electric slide rail to change the gear rack meshing state to adapt to screws of different lengths. The first motor drives the rotating frame, and the four groups of sliding frames are linked by the first and second rotating plates to synchronously control the rotation angle and tightening number of the four-corner screwdriver heads. Through the combination of the industrial robot with magnetic attraction and gear rack adjustment mechanism, fast and accurate screw positioning is achieved. The synchronous operation of the four corners greatly improves the assembly efficiency. It is compatible with a variety of charging pile models without frequent replacement of fixtures, which significantly enhances the flexible production capacity of the production line.

[0016] 2. The present invention proposes a new energy charging pile assembly device based on an industrial robot. When the screw is tightened normally, the cylinder pushes the screwdriver head close to the screw, and the lifting rod and the second positioning rod rigidly transmit torque through the clamping rod and the clamping slot structure. When the screw is stuck, the resistance is transmitted through the second positioning rod, and the clamping rod compression spring disengages the connecting tube from the transmission component, interrupting the power transmission. The innovative overload protection mechanism can quickly respond to abnormal resistance and interrupt the power transmission in time, effectively avoiding damage to the charging pile casing and the screwdriver head due to excessive torque, significantly improving the reliability and service life of the equipment, and reducing maintenance costs.

[0017] 3. The present invention proposes a new energy charging pile assembly device based on an industrial robot. When the screwdriver head moves downward to tighten the screw, the fixed cylinder pushes the elastic telescopic rod to squeeze the bent rod, and the four-corner stabilizing frame is pulled to clamp the charging box through the sliding groove and the sliding rod structure. After the operation is completed, the spring resets the stabilizing frame to automatically withdraw. The mechanical linkage stable clamping design can effectively limit the shaking of the charging box during the screw tightening process without the need for additional sensors, significantly improving the quality of screw tightening, and cooperating with the industrial robot to realize full-process automated error prevention, reduce manual intervention, and improve the stability and consistency of assembly.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] like Figure 1-Figure 7 As shown, a new energy charging pile assembly device based on an industrial robot includes a base 1, a robotic arm 5 is installed on the top of the base 1, and a regulating mechanism 2 is provided on the lower surface of the robotic arm 5. The regulating mechanism 2 includes a control frame 201 and a rotating rod 202. The outer surface of the rotating rod 202 is fixedly connected to the rotating frame 203, the upper surface of the rotating frame 203 is fixedly connected to the electric slide rail 204, the inner surface of the electric slide rail 204 is slidably connected to the sliding seat 205, the upper surface of the sliding seat 205 is rotatably connected to the first rotating plate 206 through a bearing, the inner surface of the control frame 201 is fixedly connected to a plurality of limit rails 207, and the inner surfaces of the plurality of limit rails 207 are fixedly connected. The surfaces are all slidably connected to the sliding frame 208, the upper surfaces of multiple sliding frames 208 are fixedly connected to the fixed rod 209, the other end of the first rotating plate 206 is rotatably connected to one of the fixed rods 209, the inner surfaces of multiple sliding frames 208 are fixedly connected to the rack 210, the lower surface of the control frame 201 is provided with multiple sliding grooves 211, the inner surfaces of multiple sliding grooves 211 are slidably connected to the slider 212, the inner surfaces of multiple sliders 212 are rotatably connected to the first positioning rod 213 through bearings, the upper surfaces of multiple first positioning rods 213 are fixedly connected to the first gear 214, and multiple first gears 214 are meshed with the rack 210.

[0029] The effect is that the rotating disk 7 rotates, and the slider 212 is pulled by the pull rod 8 to slide in the slide groove 211, driving the automatic screwdriver head 314 at the bottom to be initially aligned with the threaded hole on the charging box. At this time, the rack 210 is at the position closest to the center of the control frame 201 and is not in contact with the first gear 214. The electric slide rail 204 is started, the position of the sliding seat 205 is adjusted, and the meshing process of the first gear 214 and the rack 210 is changed, thereby controlling the number of rotations of the second rotating plate 9 and the automatic screwdriver head 314 to adapt to screws of different lengths.

[0030] like Figure 1-Figure 7As shown, the inner surface of the rotating frame 203 is rotatably connected to the rotating cylinder 6 through a bearing, the outer surface of the rotating cylinder 6 is fixedly connected to the rotating disk 7, the outer surface of the rotating disk 7 is rotatably connected to multiple pull rods 8 through bearings, the other ends of the multiple pull rods 8 are rotatably connected to the slider 212 through bearings, the robotic arm 5 is fixedly connected to the control frame 201, the outer surfaces of multiple fixed rods 209 are rotatably connected to the second rotating plate 9, and the adjacent second rotating plates 9 are rotatably connected through bearings, the rotating rod 202 is rotatably connected to the inner surface of the rotating cylinder 6, the outer surface of the rotating rod 202 is rotatably connected to the supporting cylinder 10 through a bearing, and the supporting cylinder 10 is fixedly connected to the limiting rail 207. A protection mechanism 3 is provided at the bottom of the control frame 201, and the protection mechanism 3 includes a support frame 301, and a cylinder 302 is installed on the lower surface of the support frame 301. The output end of the cylinder 302 is fixedly connected to the lifting plate 303, and the lower surface of the lifting plate 303 is fixedly connected to the fixed cylinder 304. The inner surface of the fixed cylinder 304 slides The connecting plate 305 is rotatably connected to the upper surface of the connecting plate 305, and the connecting cylinder 306 is rotatably connected to the inner surface of the first positioning rod 213. The lifting rod 307 is movably connected to the connecting cylinder 306. The inner surface of the connecting cylinder 306 near the bottom is slidably connected to the second positioning rod 308. The upper surface of the connecting cylinder 306 is provided with a card slot 309, and the outer surface of the connecting cylinder 306 near the bottom is provided with a positioning slot 310. The lifting rod 307 is connected to the second positioning rod 308. The outer surface of 8 is fixedly connected with a clamping rod 311, the top clamping rod 311 is slidably connected to the clamping slot 309, the bottom clamping rod 311 is slidably connected to the positioning slot 310, the lower surface of the connecting plate 305 is fixedly connected with a first spring 312, the other end of the first spring 312 is fixedly connected to the fixed cylinder 304, the lower surface of the second positioning rod 308 is installed with an automatic screwdriver head 314, the support frame 301 is fixedly connected to the slider 212, and the lifting plate 303 is rotatably connected to the lifting rod 307.

[0031] The effect is that the rotating frame 203 rotates, thereby adjusting the electric slide rail 204 and the sliding seat 205 to the corresponding position. At this time, the sliding seat 205 drives the first rotating plate 206 to rotate around the rotating rod 202 as the center of the circle, and the other end of the first rotating plate 206 drives the sliding frame 208 to slide along the limiting rail 207 through the fixed rod 209. Since the second rotating plate 9 connected to the outer surface of the fixed rod 209 rotates to form a linkage closed loop, the four sliding frames 208 move synchronously, driving the internal rack 210 to approach the first gear 214 and engage with it, driving the first positioning rod 213 to rotate, thereby controlling the number of rotations of the automatic screwdriver head 314. During normal screw tightening operation, the cylinder 302 pushes the lifting plate 303 downward, driving the fixed cylinder 304, the connecting cylinder 306 and the automatic screw tightening When the screwdriver bit 314 is close to the screw, the lifting rod 307 and the second positioning rod 308 cooperate with the slot 309 and the positioning slot 310 of the connecting tube 306 through the clamping rod 311 to maintain a rigid connection and transmit the torque for tightening the screw. When an overload such as the screw getting stuck occurs, the resistance on the screwdriver bit increases and is transmitted to the connecting tube 306 through the second positioning rod 308 and the clamping rod 311 thereon. At this time, the lifting rod 307 continues to rotate, and the clamping rod 311 connected to its surface pushes the connecting tube 306 downward, and at the same time compresses the first spring 312 through the connecting plate 305, the top clamping rod 311 disengages from the clamping slot 309, and the bottom clamping rod 311 moves up along the positioning slot 310, and the rigid connection between the connecting tube 306, the lifting rod 307 and the second positioning rod 308 fails, thereby avoiding damage to the equipment due to overload.

[0032] like Figure 1-Figure 7 As shown, a stabilizing mechanism 4 is provided at the bottom of the fixed cylinder 304, and the stabilizing mechanism 4 includes a stabilizing frame 401, and the outer surface of the support frame 301 is fixedly connected to a stabilizing rail 402, and the stabilizing frame 401 is slidably connected to the stabilizing rail 402, and a second spring 403 is fixedly connected between the stabilizing rail 402 and the stabilizing frame 401, and the outer surface of the support frame 301 is rotatably connected to a bent rod 404 through a bearing, and the outer surface of the stabilizing frame 401 is fixedly connected to a sliding rod 405, and a sliding groove 406 is provided on the surface of the bent rod 404, and the sliding rod 405 is slidably connected to the sliding groove 406, and the outer surface of the fixed cylinder 304 is fixed. It is connected to a connecting plate 407, and an elastic telescopic rod 408 is fixedly connected to the lower surface of the connecting plate 407. The elastic telescopic rod 408 is in contact with the bent rod 404. A first motor 11 is installed on the outer surface of the control frame 201, and the output end of the first motor 11 is fixedly connected to the rotating rod 202. The outer surface of the control frame 201 is rotatably connected to the mounting rod 12 through a bearing. The mounting rod 12 and the outer surface of the rotating cylinder 6 are both fixedly connected to the second gear 13, and the two second gears 13 are meshed together. A second motor 14 is installed on the outer surface of the control frame 201, and the output end of the second motor 14 is fixedly connected to the mounting rod 12.

[0033] The effect is that when the automatic screwdriver head 314 moves downward to tighten the screw, the fixed cylinder 304 moves downward to push the elastic telescopic rod 408, and the elastic telescopic rod 408 squeezes the bent rod 404 to make it rotate around the bearing. The rotation of the bent rod 404 cooperates with the sliding groove 406 and the sliding rod 405 to pull the stabilizing frame 401 to slide along the stabilizing rail 402 toward the charging box. The stabilizing frames 401 at the four corners jointly position and clamp the charging box. When the screw tightening is completed and the elastic telescopic rod 408 moves upward, the second spring 403 is reset and the stabilizing frame 401 leaves the charging box.

[0034] Working principle: the robot arm 5 moves to the charging box assembly station, and the internal magnetic structure of the automatic screwdriver head 314 is started to absorb the screws. At this time, the second motor 14 drives the rotating cylinder 6 to rotate through the mounting rod 12 and the meshing second gear 13, and the rotating disk 7 rotates accordingly. The slider 212 is pulled by the pull rod 8 to slide in the slide groove 211, driving the automatic screwdriver head 314 at the bottom to be initially aligned with the threaded hole on the charging box. At this time, the rack 210 is at the position closest to the center of the control frame 201 and has no contact with the first gear 214. The electric slide rail 204 is started, and the position of the sliding seat 205 is adjusted to change the meshing process of the first gear 214 and the rack 210, thereby controlling the number of rotations of the second rotating plate 9 and the automatic screwdriver head 314. For screws of the same length, the first motor 11 drives the rotating rod 202 to rotate, driving the rotating frame 203 to rotate, thereby adjusting the electric slide rail 204 and the sliding seat 205 to the corresponding position. At this time, the sliding seat 205 drives the first rotating plate 206 to rotate around the rotating rod 202 as the center of the circle, and the other end of the first rotating plate 206 drives the sliding frame 208 to slide along the limiting rail 207 through the fixed rod 209. Since the second rotating plate 9 connected to the outer surface of the fixed rod 209 rotates to form a linkage closed loop, the four sliding frames 208 move synchronously, driving the internal rack 210 to approach the first gear 214 and mesh with it, driving the first positioning rod 213 to rotate, thereby controlling the number of rotations of the automatic screwdriver head 314. During normal screw tightening operations, the cylinder 302 pushes the lifting The plate 303 moves downward, driving the fixed cylinder 304, the connecting cylinder 306 and the automatic screwdriver head 314 to approach the screw. A vertical slot is provided on the lifting rod 307, and a block is provided inside the first positioning rod 213. The block slides inside the vertical slot, so that when the first positioning rod 213 rotates, the lifting rod 307 can be driven to rotate synchronously. The lifting rod 307 and the second positioning rod 308 cooperate with the slot 309 and the positioning slot 310 of the connecting cylinder 306 through the block rod 311 to maintain a rigid connection and transmit the screw tightening torque. When an overload such as a screw jam occurs, the resistance of the screwdriver head increases and is transmitted to the connecting cylinder 306 through the second positioning rod 308 and the block rod 311 thereon. At this time, the lifting rod 307 continues to rotate, and the block rod 311 connected to its surface The connecting tube 306 is pushed downward, and the first spring 312 is compressed by the connecting plate 305 at the same time. The top clamping rod 311 is disengaged from the clamping slot 309, and the bottom clamping rod 311 moves up along the positioning slot 310. The rigid connection between the connecting tube 306 and the lifting rod 307 and the second positioning rod 308 fails to work, avoiding damage to the equipment due to overload. When the automatic screwdriver head 314 moves downward to tighten the screws, the fixed tube 304 moves downward to push the elastic telescopic rod 408. The elastic telescopic rod 408 squeezes the bent rod 404 to rotate around the bearing. The rotation of the bent rod 404 cooperates with the sliding slot 406 and the sliding rod 405 to pull the stabilizing frame 401 to slide along the stabilizing rail 402 toward the charging box. The stabilizing frames 401 at the four corners jointly position and clamp the charging box. When the screwing is completed,When the elastic telescopic rod 408 moves upward, the second spring 403 is reset and the stabilizing frame 401 leaves the charging box.

[0035] The above description is merely a preferred embodiment of the present invention and does not constitute any other form of limitation to the present invention. Any person skilled in the art may utilize the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes for application in other fields. However, any simple modification, equivalent change, and modification of the above embodiments made in accordance with the technical essence of the present invention without departing from the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
