DETAILED DESCRIPTION

[0021] The specific implementation of the utility model will be described in further detail below in combination with the drawings and embodiments. The following embodiments are used to illustrate the utility model, but not to limit the scope of the utility model.

[0022] As Figure 1 And Figure 2As shown, the utility model provides a kind of anti-explosion system, it includes rack 1, manipulator 2, infrared thermal imaging 3, cutting assembly 4 with cutting port, anti-explosion device 5, processor 6 and the mounting platform 7 for placing to be handled material, rack 1 is the support structure of entire system, carries and fixes all other components, mounting platform 7 is installed with cutting assembly 4 in rack 1, and cutting assembly 4 is located the side of mounting platform 7, to cut to be handled material, infrared thermal imaging 3 is towards cutting port setting, can monitor the temperature distribution situation in cutting area in real time, to detect any abnormal high temperature point when material is cut;Manipulator 2 is connected with rack 1, and located above mounting platform 7, to carry to be handled material to preset position or anti-explosion device 5, manipulator 2, infrared thermal imaging 3 and cutting assembly 4 are electrically connected with processor 6.

[0023] Based on the above structure, by infrared thermal imaging 3 monitoring cutting process, so that the local overheating point that can appear in cutting process can be captured in very short time, provide earlier warning than traditional smoke alarm 10, when processor 6 receives abnormal temperature alarm, can immediately carry to be handled material to anti-explosion device 5 by manipulator 2, take measures to prevent the occurrence of fire or explosion.

[0024] The handled material of this embodiment is old battery, and the anti-explosion system is used for anti-explosion of old battery recycling cutting, and the anti-explosion device 5 can be a device for releasing fire extinguishing agent and cooling liquid or a barrel filled with fire-retardant liquid such as water, which is not particularly limited herein. It should be noted that the way of obtaining the temperature change process over time by the infrared thermal imaging 3 and the way of determining whether it is at an abnormal temperature by the processor 6 can be realized by existing methods. Understandably, the anti-explosion device 5 can be moved.

[0025] As shown in the drawings, Figure 1 Manipulator 2 includes first driving assembly 21, connecting piece 22, centering assembly 23 and pushing structure 24, first driving assembly 21 is connected with rack 1, and is connected with centering assembly 23 and pushing structure 24 through connecting piece 22, to drive centering assembly 23 to move to specified position, pushing structure 24 is located on the side of centering assembly 23 away from cutting port. Understandably, the connecting piece 22 of the embodiment is a bridge between the first driving assembly 21 and the centering assembly 23, which can be a connecting rod, a joint or other forms of mechanical coupler, to transmit power from the driving assembly and realize the required multi-degree-of-freedom motion, not only play the role of physical connection, but also allow manipulator 2 to have flexibility while maintaining rigidity.

[0026] In the process of cutting the power battery for recycling, the manipulator 2 can position the battery on the mounting platform 7 by the centering assembly 23 according to the instructions from the processor 6, and push to the specified position for cutting operation by the pushing structure 24. If the infrared thermal imager 3 detects abnormal conditions, the processor 6 can also instruct the pushing structure 24 to quickly push the battery into the safety area or the anti-explosion device 5, thereby avoiding potential safety risks, not only improving work efficiency, but also enhancing the safety of the entire system.

[0027] As shown in Figure 3 The centering assembly 23 includes two oppositely arranged clamping jaws 231 and a first driving member 232, and the output end of the first driving member 232 is connected with the corresponding clamping jaw 231 to drive the clamping jaw 231 to clamp or release.

[0028] The first driving member 232 of the embodiment can be an electric motor, a pneumatic cylinder or a hydraulic cylinder, etc., and the output end of the first driving member 232 is connected with the clamping jaw 231. When the driving member receives an instruction, it will generate a force to push or pull the clamping jaw 231, so that they approach each other (close) or move away from each other (open). By controlling the opening and closing degree of the clamping jaw 231, the embodiment can ensure that the material is firmly gripped and moved during the carrying process, preventing it from slipping or being damaged; at the same time, when the material is determined to be located on the mounting platform 7, the material is positioned so that the pushing structure 24 can push the material to the specified position for cutting.

[0029] In some embodiments, the first driving assembly 21 includes a second driving member 211, a first sliding rail 212, a chain and a mounting seat 213. The chain is installed on the first sliding rail 212, the mounting seat 213 is connected with the chain and installed on the first sliding rail 212, and the second driving member 211 is connected with the chain to drive the mounting seat 213 to slide along the length direction of the first sliding rail 212. The mounting seat 213 is connected with the centering assembly 23 through the connecting member 22.

[0030] The first sliding rail 212 of the embodiment provides a straight-line motion guide path, ensuring that the mounting seat 213 can only move in a predetermined direction (i.e. the length direction of the first sliding rail 212). The second driving member 211 is an electric motor (such as a stepper motor or a servo motor) for providing power to drive the chain to move. When the motor receives a control signal, it will rotate and transmit power to the chain through a gear or other transmission device. The chain moves and drives the mounting seat 213 connected therewith to slide along the first sliding rail 212, so that the centering assembly 23 and the pushing structure 24 carried by the mounting seat 213 are synchronously displaced with the movement of the chain, thereby realizing the spatial positioning function of the end effector (i.e. the centering assembly 23) of the entire manipulator 2.

[0031] In some embodiments, the pushing structure 24 comprises a pushing plate 241 and a second driving assembly 242, the second driving assembly 242 is connected with the connecting member 22, and the second driving assembly 242 is connected with the pushing plate 241 to drive the pushing plate 241 to push the material to be processed.

[0032] The pushing plate 241 of the embodiment is a component directly in contact with the material to be processed, which is a plate-shaped structure with a certain area and a flat surface. In the case where the material does not need to be clamped, the position of the material is adjusted by physical contact. The second driving assembly 242 is responsible for providing power to drive the pushing plate 241 to move. When the driving member receives a control signal, it will push the pushing plate 241 to move according to the set direction and force, so as to realize the operation of advancing, retreating and stopping of the pushing plate 241, and ensure that the material can be accurately pushed to the required position.

[0033] For example, in some cases, the battery may be unstable or difficult to be directly grabbed by the centering assembly 23. At this time, the pushing plate 241 can gently push the battery to the correct position without damaging the battery, facilitating the subsequent cutting operation. Or, if the infrared thermal imager 3 detects an abnormal situation, such as the battery starts to overheat, the processor 6 can immediately instruct the second driving assembly 242 to act, and quickly push the battery to the explosion-proof device 5 or other safe area through the pushing plate 241.

[0034] In some embodiments, the second driving assembly 242 comprises a through-type motor 2421, a second sliding rail 2422, a mounting block 2423, a support 2424 and a screw rod 2425. The support 2424 is connected with the connecting member 22 to provide a platform for mounting the above-mentioned structure. The second sliding rail 2422 is installed on the support 2424, and the mounting block 2423 is slidingly installed on the second sliding rail 2422. The pushing plate 241 is installed on the mounting block 2423. The second sliding rail 2422 provides a straight-line motion guide path for the mounting block 2423, ensuring that the pushing plate 241 can move smoothly along the predetermined direction. The through-type motor 2421 is installed at one end of the second sliding rail 2422, which serves as a power source to provide the necessary rotating force for the entire pushing structure 24. It can accurately control the rotation angle and speed of the screw rod 2425 according to the instructions issued by the processor 6, so as to realize the precise control of the position of the pushing plate 241. The screw rod 2425 is connected with the through-type motor 2421 and passes through the through-type motor 2421 to be connected with the pushing plate 241. When the motor rotates, the screw rod 2425 rotates, driving the pushing plate 241 connected therewith to move axially along the screw rod 2425, ensuring that the pushing plate 241 maintains high positioning accuracy and smoothness during movement.

[0035] In some embodiments, the manipulator 2 further comprises a limiting plate 25, a sensing sheet 26 and a plurality of limiting sensors 27. The limiting plate 25 is installed at the end of the screw 2425 away from the push plate 241, and functions as a mechanical limiting device, serving as a physical barrier to prevent the screw 2425 and the components connected thereto from exceeding the predetermined stroke range. The sensing sheet 26 is installed on the limiting plate 25 and moves synchronously with the screw 2425. The plurality of limiting sensors 27 are arranged on the connecting piece 22 along the length direction of the screw 2425, and are used to monitor the position of the push plate 241 to ensure that it moves within the set range, thereby limiting the maximum stroke of the push plate 241 and avoiding damage to the equipment or danger caused by unexpected situations.

[0036] As shown in Figure 4 The cutting assembly 4 comprises a first knife 41, a second knife 42, a fourth driving member 43, a third sliding rail 44 and a sliding block 45. The cutting edges of the first knife 41 and the second knife 42 are arranged facing each other to form a cutting opening. The first knife 41 is installed on the rack 1, and the second knife 42 is installed on the sliding block 45. Through the relative movement of the two knives, precise cutting operations can be performed on the material to be processed (such as a power battery), making the cutting process more stable and controllable. The sliding block 45 is slidingly installed on the third sliding rail 44, which provides a straight-line motion guide path for the sliding block 45, ensuring that the second knife 42 can move smoothly in the predetermined direction, thereby improving the accuracy and consistency of the cutting. The fourth driving member 43 is a motor (such as a stepper motor or a servo motor) installed on the rack 1, and is connected to the sliding block 45 through a gear transmission or other forms of power transmission mechanism to drive the second knife 42 to move away from or approach the first knife 41. When the fourth driving member 43 receives a control signal, it drives the sliding block 45 to move along the third sliding rail 44, thereby driving the second knife 42 to approach or move away from the first knife 41.

[0037] In some embodiments, the cutting assembly 4 further comprises a pressing plate assembly 8. The pressing plate assembly 8 comprises a pressing plate 81 and a fifth driving member 82. The pressing plate 81 is a flat plate structure located above the material to be cut (such as a power battery). The fifth driving member 82 is a motor (such as a stepper motor or a servo motor) installed on the rack 1 and connected to the pressing plate 81 to drive the pressing plate 81 to move up and down, so that the pressing plate 81 can fix the material on the mounting platform 7 by applying appropriate pressure, preventing it from moving or sliding.

[0038] In this embodiment, the pressing plate assembly 8 is provided to firmly press the power battery on the mounting platform 7 before cutting. Even if vibration or force is generated during the cutting process, the battery will not displace, thereby ensuring the accuracy of the cutting path.

[0039] In some embodiments, an outreach plate 9 is further included, which is installed on the frame 1 and connected with the infrared thermal imager 3, and provides a platform for the infrared thermal imager 3 to be placed in a more suitable position to cover a larger monitoring area or obtain a better observation angle.

[0040] An alarm 10 is further included, which is installed on the frame 1 and electrically connected with the processor 6, for alarming to prompt the staff, and a touch screen 11 can be further provided for convenient operation, and an emergency stop switch 12 can be further provided for emergency shutdown.

[0041] The working process is as follows: the power battery is placed on the installation platform 7, the second driving member 211 of the manipulator 2 drives the centering assembly 23 to move to the position of the power battery, then the first driving member 232 drives the jaws 231 to move towards each other to clamp the power battery and perform centering processing (it should be noted that the clamping force is intended to center it and does not interfere with the movement of the push plate 241), then the through-type motor 2421 is used to drive the push plate 241 to move to push the power battery to move to the cutting opening, and the fourth driving member 43 drives the second knife 42 to move towards the first knife 41 to cut the power battery; if the cutting is normal, the subsequent centering assembly 23 drives the cut power battery to retreat, and if the infrared thermal imager 3 captures a local overheating point that may occur during cutting, the processor 6 controls the push plate 241 to push the power battery to drop to the anti-explosion device 5 to avoid the occurrence of explosion.

[0042] In summary, the anti-explosion system provided by the embodiments of the present application can monitor the cutting process through the infrared thermal imager 3, so that a local overheating point that may occur during cutting can be captured in a very short time, and a more early warning than the traditional smoke alarm 10 is provided, and when the processor 6 receives an abnormal temperature alarm, the material to be processed can be immediately transported to the anti-explosion device 5 by the manipulator 2 to take measures to prevent the occurrence of fire or explosion.

[0043] The above only describes the preferred embodiments of the present application, and it should be noted that for ordinary skilled persons in the technical field, some improvements and replacements can be made without departing from the technical principles of the present application, and these improvements and replacements should also be considered as the protection scope of the present application.
