Abstract: A die-cutting device includes a conveying mechanism configured to convey an electrode plate including uncoated and coated regions connected to each other, a cutting mechanism located on one side of the electrode plate in a thickness direction and configured to cut the uncoated region to form a scrap portion and a tab connected to the coated region, a first limiting member located between the electrode plate and the cutting mechanism in the thickness direction and provided with a cutting hole that allows laser light from the cutting mechanism to pass through and matches a cutting trajectory of the laser light, and a second limiting member located on a side of the electrode plate facing away from the first limiting member in the thickness direction and configured to cooperate with the first limiting member to limit the electrode plate in the thickness direction.

Abstract: Embodiments relate to the technical field of waste collection, in particular to waste collection equipment, which includes a temporary storage tank, a pressing tank and a pressing mechanism; the temporary storage tank is configured for receiving and temporarily storing wastes produced by die cutting equipment; the pressing tank is configured for carrying the wastes in the temporary storage tank; the pressing mechanism is configured for compressing the wastes in the pressing tank; the temporary storage tank is provided with a first blanking port, which is configured for communicating the temporary storage tank with the pressing tank; the first blanking port is provided with a first valve; and the first valve is configured for opening or closing the first blanking port to control whether the temporary storage tank discharges the wastes.
