Abstract: A vacuum coating device for a flexible substrate is provided, including a vacuum coating chamber and a transition chamber which are connected to each other. The vacuum coating chamber and the transition chamber communicate with each other through a slit. The vacuum coating device further includes a cooling roller, which is fixed in the transition chamber through a tension adjusting component. The cooling roller includes a roller body and a shaft, the roller body is fixedly installed on the shaft, and the roller body and the shaft are coaxial. Multiple heat dissipation passages are provided in the roller body along an axial direction of the roller body. Good cooling function is achieved and the flexible substrate is prevented from generating winkles.

Abstract: A wiring machine includes a lever group and magnets. The lever group includes a plurality of lever arms which are spaced apart and a plurality of rotary shafts on each of which one lever arm is mounted correspondingly so as to facilitate the rotate rocking motion of the lever arms. One end of each lever arm is provided with a wire gripper and the other end is provided with an attraction head. The magnets are arranged in association with the plurality of attraction heads.

Abstract: A drying box for storing solar cell chips includes a box body (1). Within the box body is installed a top cover (2) that is reversibly opened and divides an inner chamber of the box body into a storage chamber (13) at a lower part and a temporary storage chamber (14) at an upper part, and a side wall of the temporary storage chamber is provided with a purge hole (3). The drying box further includes a control cabinet (4) disposed at one end of the box body. The control cabinet is provided with a central controller as well as a purge controller and a drive device (5) electrically connected to the central controller. An inlet end of the purge controller is connected to a gas source and an outlet end is connected to the purge hole through a gas pipe. The drive device is connected to the top cover.

Abstract: The present application provides a simulation module of a solar cell module and a method for manufacturing a simulation cell chip layer. The simulation module of the solar cell module includes a support plate; a first Teflon layer placed on the support plate; a cell chip layer placed on the first Teflon layer; a second Teflon layer placed on the cell chip layer; and a foam layer placed on the second Teflon layer.

Abstract: The present disclosure discloses a sputter coating device and method for a solar cell. The sputter coating device includes a target for sputtering to a substrate, a blocking unit between the target and the substrate, and the orthographic projection of the blocking unit on the substrate partially coincides with the orthographic projection of the target on the substrate.
