[0042] Further, a blanking port 8 is formed in one end surface of the base 1 close to the tool holder 7.

[0043] Further, the base 1 is provided with a plurality of guide posts 9, and the substrate 2 is provided with guide sleeves 10 that cooperate with the guide posts 9.

[0044] Further, the air outlet holes 51 are inclined.

[0045] Further, a frame 11 is further included. The substrate 2 and the base 1 are both arranged inside the frame 11. A sensor 12 is arranged on the side wall of the frame 11 to detect the position of the tool 4; the distance between the bottom surface of the pressing block 5 and the tool holder 7 is less than the distance between the cutting edge part of the tool 4 and the tool holder 7. The cutting edge part of the tool 4 is the bottom of the tool 4, that is, the cutting end for cutting the battery tab. When the elastic member 14 is compressed, the distance between the bottom surface of the pressing block 5 and the tool holder 7 is greater than the distance between the cutting edge part of the tool 4 and the tool holder 7, so that the cutting edge part of the tool 4 cuts the battery tab.

[0047] The working principle of the present utility model:

[0048] The utility model is provided with a lifting component 3 to drive the substrate 2 to move up and down, so as to drive the cutting tool module to cut the battery tab. The cutting tool module has a pressing block 5 to press the battery tab. There is a vertical height difference between the cutting tool 4 and the pressing block 5. The distance between the pressing block 5 and the tool holder 7 is less than the distance between the cutting tool 4 and the tool holder 7. The battery tab first contacts the pressing block 5. After the elastic member 14 of the pressing block 5 is compressed to the maximum compression amount, it abuts against the tool holder 7 and stops moving. During the compression process of the elastic member 14, the distance between the cutting edge of the cutting tool 4 and the tool holder 7 gradually becomes less than the distance between the pressing block 5 and the tool holder 7. When the pressing block 5 abuts against the tool holder 7 and stops moving, the cutting edge of the cutting tool 4 continues to move downward through the contact surface between the pressing block 5 and the tool holder 7, so as to cut the pressed battery tab; The cutting tool module is detachably connected to the substrate 2, which is convenient for replacing the cutting tool and adjusting the cutting accuracy. The mounting unit 6 and the cutting tool 4 are detachably connected by a first locking member. The cutting tool 4 is located in the mounting groove 21, and the mounting groove 21 is vertically arranged to define the horizontal position of the cutting tool 4 and ensure the cutting accuracy after replacing the cutting tool module. The mounting unit 6 is detachably connected to the substrate 2 by a second locking member. The pressing block 5 can be fitted on the mounting unit 6 through the elastic member 14. The elastic member 14 can be selected from elastic connectors such as springs. In this embodiment, the spring is sleeved on the connecting shaft to connect the pressing block 5 to the substrate 2. Both the first locking member and the second locking member can be selected from detachable connectors such as screws or bolts for detachable fixed connection.

[0049] The lifting component 3 can be composed of a telescopic mechanism such as a cylinder. In this embodiment, the cylinder can be arranged at the center of the top of the frame 11 and penetrate through the top of the frame 11. The telescopic end of the cylinder can drive the substrate 2 to move up or down.

[0050] To improve the lifting and moving accuracy of the substrate 2, a guide post 9 and a guide sleeve 10 are provided to cooperate with each other to ensure the fitting accuracy of the up and down movement of the tool 4. High-precision guide post 9 and guide sleeve 10 are selected for this structure. In this embodiment, six guide posts 9 and six guide sleeves 10 are selected, and the accuracy requirement for movement fitting is ±0.01 mm to ensure the height accuracy movement of the substrate 2. The base 1 is equipped with a blanking port 8 with two cutting edges for removing the waste of the tab. The tool holder 7 is an installation component of the base 1. In this embodiment, both sets of tool holders 7 can be detachably connected to the base 1 by means of screw locking. The base 1 and the tool holder 7 are fixed and immovable components, and the battery tab is directly seated on the tool holder 7. The cutting tool module drives the substrate 2 to cut the battery tab. During the cutting process, a cutting-in-place sensor is provided to detect the position of the tool 4 and effectively prevent overshoot of the tool 4. In addition, when replacing the tool holder 7 or the cutting tool module manually, the positioning and locking structure 13 can be inserted into the braking hole. The braking hole is provided on the frame 11 to cooperate with the positioning and locking structure 13 to fix the position of the substrate 2 and prevent damage to the operator during the disassembly process, effectively increasing the safety protection for the operator. The present utility model is provided with two tools 4, which can be driven by a single substrate 2 to cut simultaneously, greatly improving the processing efficiency.

[0051] The tool 4 can be selected with a tungsten carbide cutting tool inserted. The cutting edge of the cutting tool is at a 45° angle. The cutting tool as a whole is also equipped with an air nozzle 52. Airflow can be introduced through the air nozzle 52. A pipeline or an air cavity can be arranged inside the pressing block 5, and the pipeline or the air cavity finally outputs the airflow through the air outlet holes 51. Multiple air outlet holes 51 can be arranged side by side obliquely, and the air outlet holes 51 can present a 60° trend, which can well blow down the cut tab waste through the air outlet. The tool 4 and the installation unit 6 are detachably fixedly connected and locked. During the process of repairing the cutting tool, the reference plane will not change, ensuring that the original position and accuracy are maintained when reinstalled into the mechanism.

[0052] The technical means disclosed in the solution of the present utility model are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present utility model.
