摘要： An embodiment of the present invention provides a secondary battery electrode production system comprising a notching portion, wherein the notching portion includes a laser portion configured to irradiate the electrode material with a laser beam along a notching line, and a pusher portion disposed above the electrode material, and the pusher portion comprises a pusher in contact with the electrode material and an air blower connected to the pusher, wherein the pusher, during notching, makes contact with an area of the electrode material excluding the notching line, fixing the electrode material while fixing both a coated portion and a non-coated portion of the electrode material, wherein the pusher includes a lower block in contact with the electrode material, an upper block coupled to the lower block, and an air nozzle portion that corresponds to a gap between the lower block and the upper block, and the pusher includes a first pusher and a second pusher, wherein the first pusher and the second pusher are spaced apart from each other in a front-and-rear direction, and the first pusher presses both the coated portion and the non-coated portion, while the second pusher presses only the coated portion, wherein the first pusher includes a body in contact with the coated portion, and an extension portion in contact with both the non-coated portion and the coated portion and the air nozzle portion includes a first air nozzle disposed along the front-and-rear direction on the body and configured to spray air from behind scrap and a second air nozzle disposed along a left-and-right direction on the extension portion and configured to spray air from the side of the scrap.

摘要： A laser welding copper nozzle, a laser welding auxiliary device, and a laser welding apparatus. The laser welding copper nozzle has: air inlets (1) used for communication with air inlet channels (2), so that during laser welding, an air blowing apparatus blows air to the air inlets (1) through the air inlet channels (2); air outlets (3) used for communication with air extraction channels (4), so that during the laser welding, a suctioning apparatus extracts air from the air outlets (3) through the air extraction channels (4), the axis of each air inlet (1) and the axis of the corresponding air outlet (3) being on a same straight line, and a laser channel for allowing laser light to pass through during the laser welding being formed between the air inlet (1) and the air outlet (3). The axis of the air inlet (1) and the axis of the air outlet (3) are on the same straight line, so that shielding gas can be independently controlled when flowing from the air inlet (1) to the air outlet (3), such that the shielding gas forms a stable stratosphere in a welding region, so as to improve a welding protection effect, and avoid complex eddy flow or turbulent flow of the shielding gas, thus avoiding occurrence of false welding.

摘要： A processing machine (10) performs additive manufacturing processing for a workpiece with a molten material. Processing machine (10) includes a first cover (21) having a first wall (23) and a second wall (25) that face each other in a horizontal direction and forming a processing area (51) between first wall (23) and second wall (25). First wall (23) is provided with a first opening (31) allowing air to flow into processing area (51). Processing machine (10) further includes an induction flow generator (41) that generates an air flow flowing from below to upward along second wall (25). First cover (21) is provided with a second opening (33) allowing the air to flow out of processing area (51).
