[0017] In summary, the beneficial effects of the present application at least include:

[0018] 1) Through precise structural design, the cutting mechanism of the present application ensures the accuracy of the cutting position. The coordinated cooperation of the lower pressing plate, the lower punch head and the lower punch block, as well as the application of the buffer spring, make the control of the force and position during the cutting process very precise, thus achieving high-precision cutting, reducing cutting errors, and improving the consistency and quality of the product.

[0019] 2) The design of the suction component ensures that the cut NTC can be safely sucked and transported, avoiding the dropping or damage of the NTC during cutting and transportation.

[0031] An embodiment of the present application discloses a material plate cutting device.

[0032] Refer to Figure 1, The material plate cutting device includes a fixed platform 5, an NTC material plate 1, a gantry 3, a suction component 2, and a lower punching component 6. The NTC material plate 1 is arranged on the fixed platform 5. The gantry 3 is installed on one side of the fixed platform 5 and above the NTC material plate 1. A linear module 4 is provided on the gantry 3. The linear module 4 is horizontally arranged, and the suction component 2 is arranged on the linear module 4. The lower punching component 6 is arranged below the NTC material plate 1. A sensor 7 is provided on one side of the suction component 2. The sensor 7 is one of a photoelectric sensor, a capacitive proximity sensor, or a laser sensor. The setting of the sensor can detect whether the NTC material plate 1 is correctly placed on the fixed platform 5. Before cutting, if the sensor does not detect the material plate, the system can stop the operation to avoid empty cutting or damaging the equipment.

[0033] Referring to Figure 1 and Figure 2 , the suction component 2 includes a first bottom plate 21, a second bottom plate 23, and a first cylinder 22. The first bottom plate 21 is installed on the linear module 4. The first cylinder 22 is fixedly installed at the top of the first bottom plate 21. The second bottom plate 23 is slidably arranged on the first bottom plate 21 and can slide in the vertical direction. The piston rod of the first cylinder 22 is connected to the top of the second bottom plate 23. A connecting block 29 is provided on the second bottom plate 23. The connecting block 29 is slidably arranged on the second bottom plate 23 and can move in the vertical direction. A suction nozzle 26 is vertically provided at the bottom end of the connecting block 29. The bottom end of the connecting block 29 is fixedly connected to the top end of the suction nozzle 26. A second cylinder 24 and a return spring 25 are also fixedly installed on the second bottom plate 23. The return spring 25 is vertically arranged. The top end of the return spring 25 is connected to the piston rod of the second cylinder 24, and the bottom end of the return spring 25 is connected to the connecting block 29. The second cylinder 24 is fixedly installed on the second bottom plate 23, and its piston rod is connected to the top end of the return spring 25. The action of the second cylinder 24 directly affects the up and down movement of the connecting block 29, thereby adjusting the specific position of the suction nozzle 26 inside the lower pressing plate 27. By precisely controlling the position of the suction nozzle 26, the second cylinder 24 ensures that the suction nozzle 26 can correctly contact the NTC and complete the suction operation.

[0034] Referring to Figure 2 and Figure 3 , a lower pressing plate 27 is also fixedly installed on the second bottom plate 23. The lower pressing plate 27 is located below the connecting block 29. The inside of the lower pressing plate 27 is hollow. The bottom end of the suction nozzle 26 is slidably arranged inside the lower pressing plate 27. The bottom end of the lower pressing plate 27 and the bottom end of the suction nozzle 26 are on the same horizontal plane. A relief groove 28 for the NTC to enter is also provided at the bottom end of the suction nozzle 26.

[0035] Referring to Figure 1 and Figure 2The lower punch assembly 6 includes a top plate 63, an intermediate plate 62 and a bottom plate 61 which are arranged in sequence from top to bottom. The bottom plate 61 is fixed to the bottom of the NTC material plate 1 through a support column 65. The top surface of the top plate 63 fits the bottom surface of the NTC material plate 1. A lifting cylinder 64 is fixedly installed on the bottom surface of the bottom plate 61. A lower punch block 67 is fixedly installed on the top surface of the top plate 63. A mounting plate 69 is placed on the top surface of the intermediate plate 62. A lower punch 66 is penetrated on the mounting plate 69. The lower punch 66 is vertically arranged and fixedly connected to the mounting plate 69. The bottom end of the lower punch 66 passes through the intermediate plate 62 and is connected to the piston rod of the lifting cylinder 64. Figure 3 The lower punch block 67 is hollow inside, and the top of the lower punch 66 is slidably set inside the lower punch block 67. The top of the lower punch 66 is the same shape as the NTC, and the top of the lower punch 66 and the top of the lower punch block 67 are located at the same horizontal plane. A buffer spring 68 is vertically arranged between the mounting plate 69 and the top plate 63, and the top of the buffer spring 68 is connected to the bottom surface of the top plate 63, and the bottom of the buffer spring 68 is connected to the top surface of the mounting plate 69. When the lifting cylinder 64 drives the lower punch 66 to move upward and punch the NTC, the spring provides a buffering effect to avoid excessive punching force causing damage to the mechanism or inaccurate punching. The presence of the spring can absorb part of the impact force to ensure that the cutting process proceeds smoothly. After the punching is completed, the spring's rebound force will help restore the lower punch 66 to its original position. This not only prepares for the next cycle, but also ensures that the entire device maintains a consistent working state during operation.

[0036] Reference Figure 1 and Figure 2 In the implementation, the first cylinder 22 is first started to drive the lower pressing plate 27 to move downward until the lower pressing plate 27 is against the top surface of the NTC material plate 1, and then the lifting cylinder 64 is started to drive the lower punch 66 to punch the NTC material plate 1 upward, and then the lower punch 66 drives the punched NTC to enter the lower pressing plate 27, and the suction nozzle 26 moves upward, combined with Figure 3 At this time, the suction nozzle 26 is started to suck the NTC in the clearance groove 28, and the cylinder 64 is lifted to drive the lower punch 66 to reset. Due to the setting of the reset spring 25, the suction nozzle 26 can also drive the punched NTC back to the opening of the lower pressing plate 27. Finally, the linear module 4 is driven to remove the cut NTC.

[0037] In summary, through the precise cooperation of the lower pressing plate 27 and the lower punch 66, this solution can ensure the stable position and uniform cutting force of the NTC material plate during cutting. The design of the lower punch 66 matches the shape of the NTC, ensuring the accuracy of cutting. The setting of the buffer spring 68 effectively absorbs the impact force during punching, avoiding inaccurate cutting or equipment damage caused by excessive impact force. The nozzle 26 in the suction component 2 can stably suck the NTC immediately after cutting, ensuring the safe handling of the NTC. The coordinated cooperation between the nozzle 26 and the lower pressing plate 27, together with the support of the return spring 25, ensures that the cut NTC can be smoothly removed from the cutting position, avoiding the dropping or damage of the NTC. Through these designs, the entire cutting process achieves high precision and high efficiency, and ensures the integrity of the NTC, solving the technical problems of controlling the position and force and stably taking out the NTC during the cutting process of the NTC material plate.

[0038] The above are all preferred embodiments of this application. Without restricting the protection scope of this application accordingly, therefore: Any equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
