The conveying belt 2 on the conveying line 1 is used for conveying. The spacing adjusting mechanism 3 is installed on the upper surface of the conveying belt 2 and is used for preliminarily limiting and adjusting the material. When the material is conveyed to the position of the uniform distribution mechanism 4, the output end of the driving cylinder 404 is engaged with the gear 405 through the toothed rod 409, thereby driving the support shaft 407 and the horizontal swing rod 402 to rotate. Since the lengths of the two horizontal swing rods 402 are different, they will produce different swing amplitudes when rotating.

The top of the threaded rod (607) passes through the long cavity (606), and the threaded rod (607) is threadedly connected to two clamping nuts (605).

8. The process of a dry-process production equipment for button cells according to any one of claims 1-7, characterized in that: The specific production process principle is as follows: First, the positive electrode shell, negative electrode shell, electrode, separator, lithium sheet and gasket of the dry battery are assembled manually and then placed on the surface of the conveyor belt (2). The material is conveyed by the conveyor belt (2) on the conveyor line (1). On the upper surface of the conveyor belt (2), a spacing adjustment mechanism (3) is installed to initially limit and adjust the material. When the material is conveyed to the position of the uniform distribution mechanism (4), when the drive cylinder (404) is started, its output end meshes with the gear (405) through the rack (409), driving the support shaft (407) and the horizontal swing arm (402) to rotate. Since the lengths of the two horizontal swing arms (402) are different, they will produce different swing amplitudes when they rotate. The two arc-shaped distribution plates (406) will alternately block the material area, thereby achieving uniform distribution of the material, so that the material can flow into the next stage evenly. Next, the material is conveyed to the position of the pressure forming mechanism (5). The pressure forming mechanism (5) includes a second U-shaped plate (501), which is fixedly connected to the conveyor line (1) with an inverted buckle. When the pressure cylinder (502) is started, its output end moves downward to pressurize and form the material. At the same time, the clamping cylinder (503) is started, and its output end clamps the material through the V-shaped clamp (504) to ensure the stability of the material during the pressure process. Finally, when the material is conveyed to the position of the leakage identification structure (6), the leakage identification structure (6) starts to work. The height limit plate (604) can limit the height of the material to ensure the consistency of the material during the conveying process. If the material is not high enough due to leakage, it will be blocked by the height limit plate (604) and slide down onto the disc (602) through the discharge channel (603), thereby realizing the identification and separation of the leakage material.
