Abstract

This utility model relates to the field of laser cutting technology for waste batteries, and discloses a laser cutting device for waste battery recycling, including a conveyor belt on which multiple sets of batteries are equidistantly distributed. Cutting frames are fixedly installed at both ends of one side of the conveyor belt, and a laser cutting machine is fixedly installed at the top center of the cutting frames. A laser cutting head is connected to the bottom of the laser cutting machine. In this utility model, the clamping and rotating assembly, when driven, drives the first gear to rotate. Since a driving arm is rotatably installed on the side wall of the first gear, and the other end of the driving arm is rotatably installed with a pressing rod, it can drive a sealing plug installed at the other end of the pressing rod to reciprocate within a sealed container.

Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology for waste batteries, specifically a laser cutting device for recycling waste batteries. Background Technology

[0002] Currently, with the rapid development of industries such as electric vehicles and portable electronic devices, the number of waste batteries has increased dramatically. Waste batteries contain a large number of harmful substances, such as heavy metals and electrolytes. If not handled properly, they will pose a serious threat to the environment and human health. Therefore, the recycling and disposal of waste batteries has become an urgent problem to be solved.

[0003] In the recycling process of waste batteries, the cutting and separation of battery casings is one of the key steps. Traditional cutting methods, such as mechanical cutting or manual cutting, have problems such as low efficiency, low cutting precision, and easy diffusion of harmful substances. In particular, traditional cutting methods are not suitable for some battery casings with special structures or materials.

[0004] Laser cutting technology has been widely used in industrial production due to its advantages such as high precision, high efficiency, and non-contact cutting. However, in the field of waste battery recycling, the application of laser cutting technology still faces some challenges. One of the most significant issues is the smoke pollution generated during the laser cutting process. This smoke contains a large number of harmful substances, and if it is directly released into the environment, it will have a serious impact on air quality and the health of operators.

[0005] Therefore, we propose a laser cutting device for recycling waste batteries. The device not only needs to have high-precision cutting capabilities, but also needs to effectively treat the fumes generated during the cutting process to protect the environment and the health of operators. Utility Model Content

[0006] The purpose of this invention is to provide a laser cutting device for recycling waste batteries, which solves the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a laser cutting device for recycling waste batteries, comprising a conveyor belt on which multiple sets of batteries are equidistantly distributed are conveyed. A cutting frame is fixedly installed at both ends of one side of the conveyor belt. A laser cutting machine is fixedly installed at the top center of the cutting frame. A laser cutting head is installed at the bottom of the laser cutting machine. The laser cutting head penetrates the top of the cutting frame and is distributed inside the top side of the cutting frame. A fumigation hood is fixedly installed on the outside of the laser cutting head. A clamping and rotating assembly is installed in the middle of both sides of the cutting frame. The battery is positioned and rotated by the clamping and rotating assembly. A negative pressure conveying mechanism is installed at one end of the clamping and rotating assembly on one side.

[0008] Optionally, the clamping and rotating assembly includes an electric push rod rotatably mounted on the middle of both sides of the cutting frame via bearings, a gear ring fixedly mounted on the side walls of both sets of electric push rods, two sets of first gears respectively meshing with the two sets of gear rings, and a second gear meshing with one set of first gears, with the central shafts of the two sets of first gears fixedly connected by a coupling.

[0009] By adopting the above technical solution, the battery can be circumferentially cut.

[0010] Optionally, a motor is fixedly installed on one side of the bottom of the cutting frame, the motor drive output end is connected to the transmission shaft, and the other end of the transmission shaft is fixedly installed to the central shaft of the second gear.

[0011] By adopting the above technical solution, the second gear can be driven to rotate.

[0012] Optionally, the negative pressure conveying mechanism includes a drive arm rotatably mounted on the outside of the first gear on one side, a squeezing rod rotatably mounted on the other side of the drive arm, a sealing plug fixedly mounted on the other end of the squeezing rod, a sealing can sealed and connected to the sealing plug, and an air inlet pipe and an air outlet pipe respectively connected and installed on both sides of the tail end of the sealing can. The sealing can is fixedly mounted on the side wall of the conveyor belt by a clamp.

[0013] By adopting the above technical solutions, the working environment can be optimized.

[0014] Optionally, the other end of the air inlet pipe is connected to a smoke pipe, and the other end of the smoke pipe passes through the side wall of the cutting frame and is connected to the top of the smoke hood.

[0015] By adopting the above technical solution, the fumes generated by laser cutting can be absorbed.

[0016] Optionally, a one-way valve is installed on both the air inlet pipe and the air outlet pipe. The flow direction of the one-way valve on the air inlet pipe is from the smoke hood to the sealed canister, and the flow direction of the one-way valve on the air outlet pipe is from the inside of the sealed canister to the outside of the sealed canister.

[0017] By adopting the above technical solution, the internal flow rate of the air inlet pipe and the air outlet pipe can be controlled.

[0018] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0019] The technical solution of this application uses a clamping and rotating assembly to drive the first gear to rotate. Since the drive arm is rotatably mounted on the side wall of the first gear, and the other end of the drive arm is rotatably mounted on the extrusion rod, the sealing plug mounted on the other end of the extrusion rod can be driven to reciprocate within the sealing tank. When the sealing plug moves to the right within the sealing tank, a negative pressure is formed in the cavity between the sealing tank and the sealing plug. This negative pressure is then transported to the fume hood through the air inlet pipe and the smoke extraction pipe, absorbing the fumes generated by the laser cutting machine and greatly purifying the working environment.

[0020] The cutting frame has clamping and rotating components installed in the middle of both sides. The batteries are positioned and rotated by the clamping and rotating components. When multiple sets of batteries are transported into the cutting frame by the conveyor belt, the electric push rods on both sides of the cutting frame are driven synchronously. The inner sides of the two sets of electric push rods clamp the two sides of the batteries. At the same time, the drive motor drives the second gear to rotate. Since the second gear meshes with the first gear and the first gear meshes with the gear ring, the two sets of electric push rods can rotate synchronously, causing the clamped batteries to rotate. This makes it easier for the laser cutting head of the laser cutting machine to perform circumferential cutting on the battery shell. Attached Figure Description

[0026] Please see Figure 1-3This utility model provides a technical solution: a laser cutting device for recycling waste batteries, including a conveyor belt 1, on which multiple sets of batteries are equidistantly distributed are conveyed. Cutting frames 11 are fixedly installed at both ends of one side of the conveyor belt 1. A laser cutting machine is fixedly installed at the top center of the cutting frame 11. A laser cutting head is installed at the bottom of the laser cutting machine 12, penetrating the top of the cutting frame 11 and distributed inside the top side of the cutting frame 11. A fume hood 13 is fixedly installed on the outside of the laser cutting head. Clamping and rotating assemblies are installed in the middle of both sides of the cutting frame 11. The batteries pass through... The clamping and rotating assembly is positioned and rotated. A negative pressure conveying mechanism is installed at one end of the clamping and rotating assembly. The negative pressure conveying mechanism includes a drive arm 3 rotatably mounted on the outside of the first gear 22 on one side, a squeezing rod 31 rotatably mounted on the other side of the drive arm 3, a sealing plug 32 fixedly mounted on the other end of the squeezing rod 31, a sealing can 33 sealed and connected to the sealing plug 32, and an air inlet pipe 34 and an air outlet pipe 35 respectively connected to both sides of the tail end of the sealing can 33. The sealing can 33 is fixedly mounted on the side wall of the conveyor belt 1 by a clamp, which can optimize the working environment.

[0027] When the clamping rotating assembly is driven, it will drive the first gear 22 to rotate. Since the drive arm 3 is rotatably installed on the side wall of the first gear 22, and the other end of the drive arm 3 is rotatably installed with the extrusion rod 31, it can drive the sealing plug 32 installed on the other end of the extrusion rod 31 to move back and forth in the sealing tank 33. When the sealing plug 32 moves to the right in the sealing tank 33, a negative pressure is formed in the cavity between the sealing tank 33 and the sealing plug 32. The negative pressure is then transported to the fume hood 13 through the air inlet pipe 34 and the smoke pipe 14, which absorbs the smoke generated by the laser cutting machine 12, greatly purifying the working environment.

[0028] In this technical solution, the clamping and rotating assembly includes an electric push rod 2 that is rotatably mounted on both sides of the cutting frame 11 via bearings, a toothed ring 21 that is fixedly mounted on the side walls of both sets of electric push rods 2, two sets of first gears 22 that are respectively meshed with the two sets of toothed rings 21, and a second gear 23 that is meshed with one set of first gears 22. The central shafts of the two sets of first gears 22 are fixedly connected by a coupling, which can perform circumferential cutting on the battery.

[0029] After multiple sets of batteries are conveyed into the cutting frame 11 via the conveyor belt 1, the electric push rods 2 on both sides of the cutting frame 11 are driven synchronously, so that the inner sides of the two sets of electric push rods 2 clamp the two sides of the battery. At the same time, the drive motor drives the second gear 23 to rotate. Since the second gear 23 meshes with the first gear 22, and the first gear 22 meshes with the gear ring 21, the two sets of electric push rods 2 can rotate synchronously, causing the clamped battery to rotate, which facilitates the laser cutting head of the laser cutting machine 12 to perform circumferential cutting on the battery shell.

[0030] In this technical solution, the other end of the air inlet pipe 34 is connected to a smoke extraction pipe 14, and the other end of the smoke extraction pipe 14 passes through the side wall of the cutting frame 11 and is connected to the top of the smoke extraction hood 13. It can absorb the smoke generated by laser cutting. Both the air inlet pipe 34 and the air outlet pipe 35 are equipped with one-way valves. The flow direction of the one-way valve on the air inlet pipe 34 is from the smoke extraction hood 13 to the sealed container 33, and the flow direction of the one-way valve on the air outlet pipe 35 is from the inside of the sealed container 33 to the outside of the sealed container 33. This can control the internal flow of the air inlet pipe 34 and the air outlet pipe 35.

[0031] The flow direction of the one-way valve on the intake pipe 34 is from the smoke hood 13 to the sealed canister 33. When the sealing plug 32 moves to the right in the sealed canister 33, a negative pressure is formed in the cavity between the sealed canister 33 and the sealing plug 32, and the smoke is transported to the smoke hood 13 through the intake pipe 34 and the smoke pipe 14. Conversely, the flow direction of the one-way valve on the exhaust pipe 35 is from the inside of the sealed canister 33 to the outside of the sealed canister 33. When the sealing plug 32 moves to the left in the sealed canister 33, the smoke collected inside the sealed canister 33 will be discharged from the exhaust pipe 35.

[0032] In this technical solution, a motor is fixedly installed on one side of the bottom of the cutting frame 11. The motor drive output end is connected to the transmission shaft, and the other end of the transmission shaft is fixedly installed on the central shaft of the second gear 23, which can drive the second gear 23 to rotate.

[0033] The second gear 23 is driven to rotate by the drive motor. Since the second gear 23 meshes with the first gear 22 and the first gear 22 meshes with the gear ring 21, the two sets of electric push rods 2 can rotate synchronously, causing the clamped battery to rotate.

[0034] In use, a large number of batteries are first placed on the conveyor belt 1 and then transported. The clamping and rotating assembly installed on the cutting frame 11 rotates the clamped batteries. The laser cutting machine 12, fixed to the top of the cutting frame 11, cuts the rotated battery casing, making it easy for the operator to remove the battery casing. Simultaneously, when the clamping and rotating assembly is driven, it drives the first gear 22 to rotate. Since the drive arm 3 is rotatably mounted on the side wall of the first gear 22, and the other end of the drive arm 3 is rotatably mounted to the extrusion rod 31, it can drive the sealing plug 32, mounted on the other end of the extrusion rod 31, to reciprocate within the sealing container 33. When the sealing plug 32 moves to the right within the sealing container 33, a negative pressure is created in the cavity between the sealing container 33 and the sealing plug 32, and this negative pressure is released through the air inlet pipe 3. 4. The smoke is conveyed to the smoke hood 13 through the smoke pipe 14, which absorbs the smoke generated by the laser cutting machine 12, greatly purifying the working environment. At the same time, the battery is positioned and rotated by the clamping and rotating components installed in the middle of both sides of the cutting frame 11. When multiple sets of batteries are conveyed into the cutting frame 11 through the conveyor belt 1, the electric push rods 2 on both sides of the cutting frame 11 are driven synchronously, so that the inner sides of the two sets of electric push rods 2 clamp the two sides of the battery. At the same time, the drive motor drives the second gear 23 to rotate. Since the second gear 23 meshes with the first gear 22, and the first gear 22 meshes with the gear ring 21, the two sets of electric push rods 2 can rotate synchronously, and the clamped battery rotates, which makes it easier for the laser cutting head of the laser cutting machine 12 to perform circumferential cutting on the battery shell.
