[0028] Reference Figure 1 and Figure 3 , an embodiment of the utility model provides an inverted conveyor line, including a punched belt 1, a driving member 2, a vacuum chamber 3 and a blowing assembly 5, wherein the driving member 2 is used to drive the punched belt 1 to drive the electrode 6 adsorbed on the punched belt 1 for transportation, and the vacuum chamber 3 is arranged in the internal space of the punched belt 1, and a negative pressure chamber 32 is arranged inside the vacuum chamber 3, and the negative pressure chamber 32 is connected to an external vacuum device through a vacuum pipe joint 4, and the negative pressure of the negative pressure chamber 32 is controlled by the external vacuum device. The bottom of the vacuum chamber 3 is provided with a plurality of adsorption holes 31 connected to the negative pressure chamber 32, when the negative pressure chamber 32 generates negative pressure, negative pressure is also generated at the adsorption holes 31, and when the punched belt 1 is transmitted, the bottom of the vacuum chamber 3 contacts the punched belt 1, thereby adsorbing the electrode 6 on the punched belt 1.

[0029] In some embodiments, reference Figure 1 The driving member 2 includes a main driving roller 22, a passing roller 25 and a servo motor 21 that drives the main driving roller 22 to rotate. The passing roller 25 is rotatably arranged at both ends of the vacuum chamber 3 through a bracket to support the punching belt 1. The main driving roller 22 and the servo motor 21 are connected to the vacuum chamber 3 through a mounting bracket 23. The servo motor 21 drives the main driving roller 22 to rotate. The main driving roller 22 abuts against the bottom of the upper section of the punching belt 1, thereby driving the punching belt 1 to transmit under the action of friction.

[0030] Further, refer to Figure 1 The driving member 2 also includes a pressure roller 24, which is rotatably arranged on the mounting frame 23. The pressure roller 24 is used to press the top of the upper section of the punching belt 1, thereby increasing the pressure between the main driving roller 22 and the punching belt 1, improving the stability of the main driving roller 22 driving the punching belt 1 to prevent the punching belt 1 from slipping during transmission.

[0031] In this embodiment, referring to Figure 5-Figure 8 The blowing assembly 5 includes a blowing block 51 and a guide block 53. A blowing channel and a negative pressure channel 531 are provided in the guide block 53. The negative pressure channel 531 is connected to the negative pressure chamber 32 in the vacuum chamber 3. A negative pressure hole 532 connected to the negative pressure channel 531 is provided at the bottom of the guide block 53. The negative pressure adsorption force generated by the negative pressure hole 532 ensures that the electrode 6 will still be adsorbed on the punching belt 1 when it is transported to the guide block 53, thereby ensuring the stable transportation effect of the good electrode 6.

[0032] In addition, the blowing channel is connected to the external positive pressure gas generating device, and the bottom of the guide block 53 is provided with a blowing hole 533 and a blowing groove 534 connected to the blowing channel. The external positive pressure gas generating device provides positive pressure gas to be blown out from the blowing hole 533 and the blowing groove 534 through the blowing channel. The force of the positive pressure gas acting on the electrode 6 is greater than the adsorption force of the negative pressure hole 532 on the electrode 6, thereby blowing the defective electrode 6 off the punching belt 1, thereby realizing the punching work of the defective electrode 6.

[0033] Further, refer to Figure 2 The punched belt 1 is provided with a circular hole 11 and an elliptical slot 12 corresponding to the blowing hole 533 and the blowing slot 534, that is, when punching, the circular hole 11 and the elliptical slot 12 on the punched belt 1 correspond to the blowing hole 533 and the blowing slot 534, and the positive pressure gas is blown out from the circular hole 11 and the elliptical slot 12, which reduces the blocking area of the positive pressure gas caused by the punched belt 1, increases the air flow of the positive pressure gas through the punched belt 1, and thereby improves the punching effect of the defective electrode 6.

[0034] In the above embodiment, referring to Figure 4 and Figure 5 The vacuum chamber 3 is provided with a mounting opening 33, and the guide block 53 is embedded in the mounting opening 33, and the bottom of the guide block 53 is flush with the bottom of the vacuum chamber 3, thereby improving the stability of the punching belt 1 in conveying the electrode 6, and improving the reliability of the blowing assembly 5 in punching out defective electrode 6. Furthermore, a mounting plate 52 is provided between the guide block 53 and the blowing block 51. Preferably, the mounting plate 52 and the guide block 53 are integrally formed, that is, the edge of the mounting plate 52 forms a lug structure protruding from the guide block 53. The size of the mounting plate 52 is larger than the size of the mounting opening 33. The end of the mounting opening 33 is provided with a stepped groove 34. The mounting plate 52 is accommodated in the stepped groove 34. The mounting plate 52 is connected to the bottom of the stepped groove 34 by screws, thereby mounting the blowing assembly 5 on the vacuum chamber 3.

[0035] In this embodiment, referring to Figure 5-Figure 8 The blowing block 51 is provided with a blowing cavity 512 and an air inlet channel 511 connected to the blowing cavity 512. The air inlet channel 511 is connected to an external positive pressure gas generating device through a pipe joint. The blowing channel includes a first blowing channel 535 and a second blowing channel 536. The blowing hole 533 is connected to the blowing cavity 512 through the first blowing channel 535, and the blowing groove 534 is connected to the blowing cavity 512 through the second blowing channel 536.

[0036] In this embodiment, a plurality of blowing areas are provided at the bottom of the guide block 53, each of which is provided with a negative pressure hole 532, a blowing hole 533 and a blowing groove 534, and the blowing cavity 512 of each blowing area is independently provided, and the air inlet pipe connected to the blowing cavity 512 is separately connected to a solenoid valve 54, Figure 9 In this embodiment, four blowing areas A, B, C, and D are provided. The width of the blowing area corresponds to the width direction of the electrode 6. In this way, the four air inlet channels 511 can be blocked to control whether each area is blown. The electrode 6 with different width ranges can adjust the position of the electrode 6 to the corresponding appropriate blowing area, so that when the defective electrode 6 is punched, the two air inlet channels 511 in the corresponding area are used for blowing.
