The invention discloses a large flexible printed circuit (FPC) and belongs to the technical field of flexible printed circuit manufacture. The FPC comprises a plurality of FPC units arranged on the FPC and the plurality of FPC units are arranged in a staggered mode on the large FPC page. The invention further discloses a typeset method of manufacturing the FPC. The plurality of FPC units are arranged in the staggered mode on the large FPC page. According to staggered arrangement of the FPC units, stress generated is dispersed so that stress intensity is lessened, a bending ratio is reduced and yield in the process of the large FPC manufacturing and large FPC blanking is improved. The typeset method of manufacturing the FPC can be used in the manufacturing process of the FPC.

The invention relates to a weaving-in honeycomb paperboard and paper core molding structure, which is specifically used to be installed on the frame of a honeycomb board production line in a complete set of honeycomb board manufacturing equipment in the packaging industry, and belongs to the technical field of packaging machinery molding devices. The feature is that the guide groove is used to install the frame, the first forming clamp is installed on the frame, the second forming clamp is installed on the first forming clamp, the conduit is installed on the frame, and the ejector rod is installed in the conduit. The two ends of the ejector rod respectively resist the cam and the first forming clamping die. The cam shaft is installed on the frame, and the cam is installed on the cam shaft. One end of the shuttle plate is installed in the guide groove, and the other end is equipped with a mold head. Positioning pins are installed on the clamping mold. The invention has a simple, compact and reasonable structure; it can adapt to the simultaneous molding of honeycomb paperboards and paper cores of various specifications, and can be made into multi-layer honeycomb paper cores after cutting; it occupies a small area, has low manufacturing cost, no pollution, no noise, and can One person operates multiple paper core forming machines.

The robot controller is connected with the industrial robot by connecting cables. The robot controller has a case for storing the actuator controller. One side of the box has a stepped portion. The stepped portion has a connection portion, and the connection cable is extended along the one side surface in a state where the connection cable is arranged on the one side surface. A connection cable is connected to the connection part. Therefore, the robot controller can save space.

The invention provides a unipolar current cross-connected three-level sub-module, and belongs to the field of a power electronic technology and power transmission and distribution. The sub-module comprises a first DC capacitor, a second DC capacitor, a first fully-controlled power electronic switch device, a second fully-controlled power electronic switch device, a fully-controlled power electronic switch unit, a first diode, a second diode and a diode unit; and two structures of the unipolar current cross-connected three-level sub-module with forward current outflow and the unipolar current cross-connected three-level sub-module with forward current inflow are provided according to different forward current directions. According to the unipolar current cross-connected three-level sub-module provided by the invention, the quantity of output levels of the sub-module can be improved when DC fault ride-through of a modular multilevel converter is achieved; the power density of the sub-module is improved; the cost is reduced; and auxiliary drive equipment and the spatial volume are saved.

The invention discloses a box-type transformer facilitating maintenance of an internal device. The box-type transformer comprises a box, a servo motor, a transformer body and a cooling fan, wherein aside plate is arranged on one side face of the box, a first sealing door is installed at one end of a motor shaft, a lower corner of a second sealing door is connected with the side plate through a movable shaft, the other end of the motor shaft is sleeved with a first gear, a second gear is connected with a third gear through a chain, a connecting shaft penetrates through the third gear, the outer side of the connecting shaft is sleeved with a sleeve block, a fixed cylinder is fixed to the top of the transformer body, the top of a connecting rod is connected with a line storage box through aconnecting block, and a fixed rod is fixed to one side of the line storage box. Through the box-type transformer facilitating maintenance of the internal device, the transformer body in the box can beautomatically driven to slide out, the situation that a large amount of manpower needs to be consumed in a maintenance process is avoided, and the open sealing doors cannot occupy outside space.

An object of the present invention is to provide a refrigerator capable of suppressing an unnecessary space waste. The refrigerator of the present invention comprises: an operation panel (20) having afront surface member (21); a control substrate (31) provided on the back side of the front surface member (21); a substrate housing portion (41) for housing the control substrate (31) and fixing thefront surface member (21); and a heat insulating box (10) provided with a foam heat insulating material and a vacuum heat insulating material (50) between an outer case (11) and an inner case (12) forconfiguring the operation panel (20) on a side wall (12a) of the inner case (12), wherein there is no foam heat insulating material present at least near the center in the gap between the vacuum heatinsulating material (50) or the outer case (11) and the bottom of the substrate housing portion (41).

An underbody panel for a motor vehicle is composed of a lightweight sandwich material and is configured as a single part with at least one continuous folding connection (12) that extends in a transverse direction of the underbody panel and is arranged between first and second portions of the underbody panel (14). The first and second portions can be folded together via the folding connection (12)and, in the folded state, are substantially parallel to each other to reduce a size of the underbody panel during transport and storage. In this way, the underbody panel configured as a single part isprovided, storage space and transportation volume of the underbody panel can be saved, and the underbody panel is gap-free when installed on a motor vehicle.
