[0002] The battery cell outputs electrical energy through multi-layer tabs. Multi-layer tabs are usually cut by laser die-cutting to cut the multi-layer plates into tabs of special shapes.

[0003] In this regard, China's patent application number is CN201610994228.6, which discloses a laser die-cutting device for battery cell tabs. This solution mainly sprays in parallel from the side of the pole piece during the cutting process, which has a good dust removal effect; and can avoid the interference of the dust removal mechanism on the pole piece, ensuring the cutting accuracy of the tab. In addition, the present invention can achieve the cutting of tabs on both sides of the pole piece that are on the same straight line; during the cutting process, the pole piece is in a suspended state, and the cut tab will not touch obstacles and deform.

[0004] However, in the process of implementing the technical solutions in the embodiments of the present application, the inventors of the present application found that the above technology has at least the following technical problems:

[0005] 1. The side blowing method causes the dust to float, which is not convenient for dust collection. In addition, smoke and dust will appear during the laser cutting process. In order to prevent the ear from being blown out of position, a holding structure is required, which leads to a complex structure.

[0006] 2. The waste of the tabs is mostly hollow frame structures, which take up a lot of space and are entangled with each other, making them difficult to handle later. Utility Model Content

[0007] In order to make up for the above deficiencies, the present application provides a waste collection component and a multi-layer tab laser die-cutting device, aiming to improve the problems mentioned in the above background technology.

[0009] In a specific embodiment, the crushing box includes a box body, a discharge port is arranged below the box body, and a door panel is arranged on the discharge port.

[0010] In the above implementation process, the door panel is hinged on the discharge port, and the waste is discharged from the discharge port after being crushed. When the negative pressure mechanism is started, the crushing box is in a negative pressure state, and the door panel is adsorbed on the discharge port. After the negative pressure mechanism stops, the waste breaks through the door panel and is discharged.

[0011] In a specific embodiment, two crushing rollers are rotatably connected in the box body, and the two crushing rollers rotate in opposite directions. A motor is arranged on the outer wall of the box body, and the motor is power-connected to the two crushing rollers.

[0013] In a specific embodiment, each of the crushing rollers is connected to a gear, the two gears are meshed, and the output end of the motor is connected to the shaft of one of the crushing rollers.

[0014] In the above implementation process, the motor drives one of the crushing rollers to rotate, and then through the meshing of the two gears, the two crushing rollers can rotate synchronously and in opposite directions.

[0015] In a specific embodiment, the driving member includes a rocker arm, one end of the rocker arm is fixedly connected to the hinge shaft of the flap, and the other end of the rocker arm is fixedly connected to a lever.

[0016] In a specific implementation, the driving member further includes a cylinder, which is mounted on the side wall of the box body, and a cross bar is fixedly connected to the telescopic end of the cylinder, and a sliding groove adapted to the shifting rod is provided on the cross bar.

[0017] In the above implementation process, the cylinder moves the cross bar up and down when it is extended and retracted, and at the same time, the lever on the rocker arm moves in the slide slot, thereby driving the two rocker arms to deflect, and then driving the two flaps to deflect.

[0018] In a specific embodiment, the negative pressure mechanism is a vacuum cleaner.

[0019] In the above implementation process, the vacuum cleaner can be directly integrated into the side wall of the box, and can also be connected to the box through a pipeline, so as to achieve a negative pressure casing in the box.

[0020] In a second aspect, the present application further provides a multi-layer tab laser die-cutting device, comprising the above-mentioned waste collection assembly.

[0021] Compared with the prior art, the beneficial effects of the present application are: the negative pressure mechanism generates negative pressure in the crushing box, adsorbs the pole ear on the flap, facilitates cutting, and simplifies the structure. The smoke and dust can be directly sucked into the crushing box. After the cutting is completed, the drive member drives the flap to deflect and put the waste into the crushing box for crushing for subsequent processing. BRIEF DESCRIPTION OF THE DRAWINGS

The door panel 12 is hinged on the discharge port, and the waste is discharged from the discharge port after being crushed. When the negative pressure mechanism 30 is started, the crushing box 10 is in a negative pressure state, and the door panel 12 is adsorbed on the discharge port. After the negative pressure mechanism 30 stops, the waste breaks through the door panel 12 and is discharged.

[0031] See also Figure 1-Figure 4 Two crushing rollers 13 are rotatably connected in the box 11, and the two crushing rollers 13 rotate in opposite directions. A motor 14 is provided on the outer wall of the box 11, and the motor 14 is connected to the two crushing rollers 13. The motor 14 drives the two crushing rollers 13 to rotate in opposite directions, crushing the waste into small particles to avoid entanglement for subsequent processing.

[0032] See also Figure 1-Figure 4 Each crushing roller 13 is axially connected to a gear 15, and the two gears 15 are meshed. The output end of the motor 14 is connected to the shaft of one of the crushing rollers 13. The motor 14 drives one of the crushing rollers 13 to rotate, and then through the meshing of the two gears 15, the two crushing rollers 13 can rotate synchronously and in opposite directions.

[0033] See also Figure 1-Figure 4 The driving member 40 includes a rocker arm 41, one end of which is fixedly connected to the hinge shaft of the flap 20, and the other end of the rocker arm 41 is fixedly connected to a lever 42.

[0035] See also Figure 1-Figure 4 The present application further provides a multi-layer tab laser die-cutting device, including the above-mentioned waste collection component.

[0036] The working principle of the waste collection assembly is as follows: an external transport mechanism such as a manipulator places the multi-layer electrode plate on the flap 20, and the negative pressure mechanism 30 generates negative pressure in the crushing box 10 to adsorb the electrode plate on the flap 20 to prevent it from moving. The external laser cutting mechanism cuts the electrode plate into electrode ears, and the dust generated during the cutting process can be directly sucked into the crushing box 10 through the hollow flap 20. After the cutting is completed, the electrode ear is taken away by the manipulator, and then the cylinder 43 contracts to pull the cross bar 44, and the lever 42 moves in the slide slot. The two rocker arms 41 are driven to deflect, thereby driving the flap 20 to flip inward, and the waste is put into the box 11 below, and is crushed into small particles under the action of the two crushing rollers 13 for subsequent transportation and treatment. In summary, the negative pressure mechanism 30 generates negative pressure in the crushing box 10, and adsorbs the pole ear on the flap 20, which is convenient for cutting and simplifies the structure. The smoke can be directly sucked into the crushing box 10. After the cutting is completed, the flap 20 is driven to deflect by the driving member 40 to put the waste into the crushing box 10 for crushing, so as to facilitate subsequent treatment.
