Abstract: The invention relates to the technical field of automobile door frame structures and window sealing systems. The invention includes a door body, on which a window frame is arranged, and sliding grooves. A glass body flush with the door body, and one side of the glass body has a concave surface and a convex surface on the other side. At least one side of the glass body is provided with a guide piece, and the guide piece is slidably installed in the sliding groove. An arc-shaped limiting member is arranged on the guide piece. A bump limiter is arranged on the side of the guide piece. Since the bump limiter is a solid structure and the inner side of the arc-shaped limiting member is hollowed out, the bump limiter can resist greater pressure than the arc-shaped limiting member during the glass lifting process, preventing dislocation between the door and the glass to ensure good sealing between the door body and the glass body during long-term use.

Abstract: A full-tab cell production line includes a flattening unit (1), a gluing unit (2), a shell insertion unit (3), and a current collector welding unit (4) sequentially disposed in a processing direction. The flattening unit (1) includes an ultrasonic flattening sub-unit (11) and a mechanical flattening sub-unit (12). The ultrasonic flattening sub-unit (11) performs ultrasonic flattening pretreatment on an end surface of a core. The mechanical flattening sub-unit (12) is configured to mechanical flatten the end surface of the core that has undergone the flattening pre-treatment. The gluing unit (2) is configured to wrap an insulation tape around the flattened core. The shell insertion unit (3) presses the core wrapped with the insulation tape into a shell. The current collector welding unit (4) welds the current collector to two ends of a core, welds collector plates to two ends of a core that has been inserted in the shell, and bends a tab to a pre-determined angle.

Abstract: A conveying apparatus, comprising a drive conveying sub-apparatus. The drive conveying sub-apparatus comprises a first movable supporting film (81), a second movable supporting film (82), a first fixed supporting film (71), and a drive conveying mechanism. The first movable supporting film (81) and the second movable supporting film (82) are respectively located at both sides of the first fixed supporting film (71). The first movable supporting film (81) and the second movable supporting film (82) are both slidably connected with the drive conveying mechanism, so that the drive conveying mechanism drives the first movable supporting film (81) and the second movable supporting film (82) to move up and down and move forward and backward. The first movable supporting film (81), the second movable supporting film (82), and the first fixed supporting film (71) are all provided with grooves having sizes matched with the size of an object to be conveyed.
