Description

Technical Field

[0001] The present invention relates to material conveying equipment for lithium battery production, and in particular to a laser forklift AGV clip automatic docking system in the front process section of lithium batteries. Background Art

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloys as the negative electrode material and a non-aqueous electrolyte solution. They are widely used in vehicles such as automobiles and electric vehicles. Laser forklift AGVs are primarily used for flat-bed storage, shelf storage, line connection, stacking, clamping, and flipping operations. Laser forklift AGVs primarily consist of an AGV frame assembly, a safety protection system, an automatic charging system, a dispatching system, a laser navigation system, an information collection system, a wireless network system, and other ancillary equipment.

[0003] Lithium batteries are characterized by high energy, environmental friendliness, long lifespan, and portability. The production of lithium battery pole pieces is a key step in the production process. Pole piece die-cutting involves using a die-cutting machine to cut a large pole piece strip into multiple smaller strips, tailored to the specific battery model or style. The smaller strips are then stacked and placed in clips for transport.

[0004] In the lithium battery electrode supply area of ​​the lithium battery front-end process, multiple clips are placed on a tooling pallet. The clips contain stacked lithium battery electrodes. The tooling pallet with clips is pushed onto the roller cart through the entrance and exit. The roller cart is manually pushed to the nearby clip transfer area. The tooling pallet is then manually transported to a laser forklift AGV, which transports the tooling pallet with clips to the more distant lithium battery electrode utilization area.

[0051] The embodiment of the present invention solves the shortcomings of the prior art of frequently manually transporting tooling pallets containing magazines to the laser forklift AGV by providing an automatic docking system for magazines in the front process of lithium batteries, thereby achieving the technical effect of improving transportation efficiency.

[0052] The technical solution in the embodiment of the present invention is to solve the above-mentioned shortcomings. The overall idea is as follows: the laser forklift AGV of the first magazine transport vehicle moves to the area of ​​the positioning platform. A QR code for docking is affixed to the ground in front of the positioning platform. The second magazine transport vehicle carries the tooling pallet into the positioning port of the positioning platform to avoid shaking of the frame of the second magazine transport vehicle when the magazine is docked. The entrance and exit of the first roller conveyor device is aligned with the entrance and exit of the second roller conveyor device. The hook of the mobile hook device moves forward, the hook hooks the ring hook of the tooling pallet, and the hook retreats to drag the tooling pallet with the magazine to the first roller conveyor device, thereby conveniently transferring the tooling pallet with the magazine and completing the automatic docking of the magazine. The laser forklift AGV carries the tooling pallet to the next process section.

[0053] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0054] See Figures 1 to 20 , a preferred embodiment of the present invention.

[0055] A lithium battery front-end process section laser forklift AGV magazine automatic docking system includes: a first magazine transport vehicle 1, a second magazine transport vehicle 2 and a positioning seat 3, the first magazine transport vehicle 1 includes a laser forklift AGV 11, a first roller 122 type conveying device 12 and a mobile hook device 13, the second transport includes a frame 21 and a second roller 222 type conveying device 22; in this embodiment, there are six magazines 5 on the tooling tray 4, each magazine is 360mm in length, 240mm in width and 350mm in height, and the maximum load of the magazine is 25kg. The tooling pallet 4 has a fixed ring hook 41, and the tooling pallet 4 is located on the second roller 222 type conveying device 22 of the second magazine transport vehicle 2. The second magazine transport vehicle 2 enters the positioning seat 3, and the laser forklift AGV11 of the first magazine transport vehicle 1 approaches the positioning seat 3. The first roller 122 type conveying device 12 is aligned with the entrance and exit of the second roller 222 type conveying device 22, and the hook 134 of the mobile hook device 13 automatically moves forward, hooks the ring hook 41 of the tooling pallet 4, and drags the tooling pallet 4 to the first roller 122 type conveying device 12 to complete the automatic docking of the magazine.

[0056] The first roller 122 type conveying device 12 includes a first frame 121 and a first roller 122. The first roller 122 is rotatably connected to the first frame 121. Multiple first rollers 122 are arranged at intervals. The first frame 121 is slidingly connected to the body of the laser forklift AGV11. The position of the first frame 121 on the body of the laser forklift AGV11 can be adjusted to better align with the entrance and exit of the second roller 222 type conveying device 22.

[0057] The mobile hook device 13 includes a first guide rail 131, a first support base 132, a lifting drive mechanism 133, and a hook 134. The first guide rail 131 is fixedly connected to the first frame 121, the first support base 132 is slidably connected to the first guide rail 131, and the lifting drive mechanism 133 is fixedly mounted on the first support base 132. The lifting end of the lifting drive mechanism 133 is fixedly connected to the hook 134. The lifting drive mechanism 133 is an electric push rod. The mobile hook device 13 also includes a right-angle arm 135, the vertical portion of which is fixedly connected to the first support base 132, and the horizontal portion of which is fixedly connected to the lifting drive mechanism 133. The first support seat 132 is driven by an existing motor drive mechanism. The first support seat 132 moves forward from the initial position along the first guide rail 131 with the lifting drive mechanism 133. The lifting drive mechanism 133 raises the hook 134. When the hook 134 reaches the ring hook 41 of the tooling pallet 4, the lifting drive mechanism 133 lowers the hook 134, and the hook 134 hooks the ring hook 41 of the tooling pallet 4. The first support seat 132 retreats, and the hook 134 drags the tooling pallet 4 to the first roller 122 conveyor 12. The tooling pallet 4 moves on the first roller 122 until the first support seat 132 returns to its initial position and stops. When the laser forklift AGV 11 moves to the next process section, the hook 134 always hooks the ring hook 41 of the tooling pallet 4 to prevent the tooling pallet 4 from falling during transportation.

[0058] The second roller 222 type conveying device 22 includes a second frame 221 and a second roller 222. The second roller 222 is rotatably connected to the second frame 221. The second frame 221 is fixed to the top of the frame 21. Multiple second rollers 222 are arranged at intervals. The second roller 222 and the first roller 122 are in rolling contact with the tooling pallet 4, effectively reducing the friction when the tooling pallet 4 moves.

[0059] The positioning seat 3 is provided with a positioning opening 31 , the size of which matches the frame 21 , and the frame 21 of the second magazine transporter enters the positioning opening 31 to prevent the frame 21 of the second magazine transporter 2 from shaking when the magazine 5 is docked.

[0060] The first magazine transport vehicle 1 further includes a vertical drive device 14, which includes a second guide rail 141, a second support base 142, and a support arm 143. The second guide rail 141 is fixedly connected to the body of the laser forklift AGV 11, the second support base 142 is slidably connected to the second guide rail 141, the support arm 143 is fixedly connected to the second support base 142, and the first frame 121 is fixedly connected to the support arm 143. The vertical drive device 14 controls the second support base 142 to move up and down along the second guide rail 141, thereby adjusting the height of the first roller 122-type conveyor device 12 located on the support arm 143.

[0061] The first magazine transport vehicle 1 also includes a first visual sensor 15, which is fixed to the bottom surface of the first frame 121. A docking QR code 32 is affixed to the ground in front of the positioning platform. The first visual sensor 15 is used to scan and detect the QR code 32 located on the ground in front of the positioning seat 3. The docking QR code 32 is 1000 mm long. The first visual sensor 15 scans and detects this QR code, and the laser forklift AGV 11 approaches the positioning seat 3 along this QR code. The first visual sensor 15 then feeds back a signal to the mobile hook device 13, causing the hook 134 of the mobile hook device 13 to begin moving forward.

[0062] The first roller 122-type conveyor device 12 also includes a second visual sensor 16, which is fixed to the top surface of the first frame 121. Two second visual sensors 16 are respectively located on either side of the entrance and exit of the first frame 121. When a tooling pallet 4 passes through the entrance and exit of the first frame 121, the second visual sensor 16 scans the QR code attached to the magazine 5 on the tooling pallet 4 and uploads the magazine 5 information to the control platform, which records the logistics information of the magazine 5.

[0063] The first frame 121 has a left groove 1211, a middle groove 1212, and a right groove 1213. The first guide rail 131 is located in the middle groove 1212. The first rollers 122 are located in both the left groove 1211 and the right groove 1213. Thus, when the hook 134 drags the tooling tray 4, the first rollers 122 in the left groove 1211 and the right groove 1213 support the bottom sides of the tooling tray 4, making the movement of the tooling tray 4 more stable.

[0064] The first roller 122 conveying device 12 further includes guide plates 123, which are respectively fixed to the top outer edges of the left groove 1211 and the right groove 1213. The tooling tray 4 smoothly enters the first roller 122 conveying device 12 along the guide plates 123, preventing the tooling tray 4 from deviating from its position.

[0065] The second magazine transporter 2 also includes an anti-backward device 23, which is installed at the entrance and exit of the vehicle frame 21. The anti-backward device 23 includes a bracket 231, a positioning tube 232, a compression spring 233, a connecting rod 234, and a limiting seat 235. The bracket 231 is fixedly connected to the vehicle body. Strip holes 2311 are formed on both sides of the bracket 231. The connecting rod 234 is fixedly connected to the limiting seat 235. The ends of the connecting rod 234 are respectively connected to the two strip holes 2311 for vertical sliding connection. The positioning tube 232 is fixedly connected to the bracket 231. The lower end of the compression spring 233 is fixedly mounted inside the positioning tube 232, and the upper end of the compression spring 233 abuts the bottom surface of the limiting seat 235. There are multiple positioning tubes 232 and compression springs 233, which are spaced apart below the limiting seat 235. When the limiting seat 235 is subjected to a certain downward force, such as a worker pressing the limiting seat 235, the compression spring 233 begins to compress, causing the limiting seat 235 to move downward. When the top surface of the limiting seat 235 is lower than the bottom surface of the tooling tray 4, the tooling tray 4 can be pushed into or out of the vehicle frame 21 through the entrance and exit of the vehicle frame 21. When the limiting seat 235 is not subjected to a downward force, the compression spring 233 begins to reset, causing the limiting seat 235 to move upward. When the compression spring 233 is in its initial state, the top surface of the limiting seat 235 is higher than the bottom surface of the tooling tray 4, so that the tooling tray 4 on the vehicle frame 21 is blocked by the limiting seat 235. When the vehicle frame 21 of the second magazine transport vehicle is manually pushed to transport the tooling tray 4, the limiting seat 235 of the anti-backward device 23 blocks the tooling tray 4, preventing the tooling tray 4 from escaping from the entrance and exit of the vehicle frame 21, thereby enabling stable and convenient transportation of the tooling tray 4.

[0066] The top of the stopper 235 has a chamfered corner 2351. The compression spring 233 is selected with an appropriate elastic coefficient so that, when the frame 21 of the second magazine transporter 2 is transporting the tooling pallet 4, even if the tooling pallet 4 strikes the chamfered corner 2351 of the stopper 235 due to inertia, the inertial force is small, and even if the stopper 235 slightly drops, the top surface of the stopper 235 will not drop below the bottom surface of the tooling pallet 4. When an additional driving force is applied to the tooling pallet 4, this driving force causes the tooling pallet 4 to advance. When it strikes the chamfered corner 2351 of the stopper 235, the greater driving force causes the stopper 235 to drop significantly, compressing the compression spring 233. Once the top surface of the stopper 235 drops below the bottom surface of the tooling pallet 4, the stopper 235 releases its restraint on the tooling pallet 4, allowing the tooling pallet 4 to exit the frame 21 through the entrance or exit of the frame 21. The driving force is the pulling force exerted by the hook 134 of the movable hook device 13 in this embodiment to move the tooling tray 4 .

[0067] Four universal wheels 211 are installed at the bottom of the frame 21, which facilitate the turning of the frame 21 when moving, and facilitate the frame 21 to enter the positioning port 31 of the positioning seat 3. The frame 21 is spliced ​​from aluminum profiles, and the frame 21 is fixed with a loading plate 212, which is located below the second roller 222 type conveying device 22, thereby increasing the loading space of the frame 21. A baffle 213 is fixed on the top of the frame 21, and the baffle 213 is arranged opposite to the anti-backward device 23. On one side of the baffle 213, the frame 21 is installed with a push handle 214, and the staff holds the push handle 214 to push the frame 21. The baffle 213 prevents the tooling tray 4 from moving in the direction of the push handle 214.

[0068] The second roller 222 type conveying device 22 also includes a PLC. The second roller 222 is an electric roller, and the PLC is electrically connected to the electric roller. The first visual sensor 15 scans the QR code of the docking angle. When the hook 134 of the mobile hook device 13 moves forward, the first visual sensor 15 sends a signal to the PCL via wireless means. After receiving the signal, the PLC controls the electric roller to rotate, moving the tooling pallet 4 on the second roller 222 toward the anti-backward device 23. The anti-backward device 23 then blocks the tooling pallet 4. The hook 134 reaches above the ring hook 41 of the tooling pallet 4 and hooks downward on the ring hook 41. The hook 134 retreats, applying tension to the tooling pallet 4. The tooling pallet 4 forces the limit seat 235 of the anti-backward device 23 to move downward. The tooling pallet 4 passes the anti-backward device 23 and enters the first roller 122 type conveying device 12.

[0069] The working method of the laser forklift AGV magazine automatic docking system for the lithium battery front process section of the present invention is as follows: (1) The laser forklift AGV 11 of the first magazine transport vehicle 1 moves to the area of ​​the positioning seat 3, and the staff pushes the second magazine transport vehicle 2. The second magazine transport vehicle 2 carries the tooling tray 4 loaded with magazines 5, and the second magazine transport vehicle 2 enters the positioning port 31 of the positioning seat 3. (2) The first visual sensor 15 of the first magazine transport vehicle 1 scans the QR code 32 for docking located on the ground in front of the positioning seat 3. The laser forklift AGV 11 moves along the QR code and approaches the positioning seat 3. Then, the vertical drive device 14 adjusts the height of the first roller 122 type conveying device 12 so that the entrance and exit of the first roller 122 type conveying device 12 are aligned with the entrance and exit of the second roller 222 type conveying device 22. The first visual sensor 15 sends a signal to the mobile hook device 13. At the same time, the first visual sensor 15 sends a signal to the PLC of the second magazine transport vehicle 2 by wireless means. (3) The hook 134 of the mobile hook device 13 moves forward, and the PCL controls the rotation of the second roller 222. The tooling tray 4 on the second roller 222 moves toward the anti-backward device 23. The anti-backward device 23 blocks the tooling tray 4. The hook 134 reaches above the ring hook 41 of the tooling tray 4 and hooks downward on the ring hook 41 of the tooling tray 4. (4) The hook 134 moves backward, applying a pulling force to the tooling tray 4. The tooling tray 4 forces the limit seat 235 of the anti-backward device 23 to move downward. The tooling tray 4 passes over the anti-backward device 23 and enters between the guide plates 123 of the first roller 122 conveying device 12. (5) The second visual sensor 16 scans the QR code attached to the magazine 5 on the tooling tray 4 and uploads the information of the magazine 5 to the control platform. The control platform then records the logistics information of the magazine 5 and makes production scheduling in advance. (6) The hook 134 returns to the initial position, and the laser forklift AGV11 of the first magazine transport vehicle 1 carries the tooling tray 4 containing the magazine 5 to the lithium battery electrode use area of ​​the next process section.
