The invention provides a method for preparing a mask with a high aperture ratio, comprising the following steps: S1, coating a photocurable material on the surface of the mask, and performing ultraviolet light on the photocurable material in the main body area of ​​the mask and the connecting bridge reserved area. Light irradiation and curing to form a low polymer, cleaning and removing the uncured light-cured material on the surface of the connecting bridge to be corroded, and then immersing the mask plate coated with a low polymer in a corrosive solution to remove the connecting bridge to be corroded Zone, to obtain a mask plate coated with low polymer on the surface; S2: remove the low polymer on the surface of the mask plate to obtain a mask plate with a high aperture ratio. The present invention can effectively increase the aperture ratio of the mask plate by reducing the width of the connecting bridge of the main body of the mask plate, specifically, the aperture ratio can be increased by 30-50%.

The invention discloses an assembly line for bonding display screen modules. The structure includes a fixed block, a cutting device, a conveyor belt, a fixed base, and an assembly cavity. In cooperation, the cutting device is installed in the fixed block. The beneficial effect of the present invention is that the reverse movement of the roller and the conveyor belt is controlled by external mechanical force, so that the brush and the soft rod rub against the surface of the conveyor belt, and the impurities on the surface are cleaned. And because the brush and the soft rod are both tough materials, the brush and the soft rod will return to their original shape after they are separated from the surface of the conveyor belt. The combination of the fixed scraper and the movable scraper is used to remove the dried rubber from both sides to the middle, and the dropped rubber enters the slag collection tank to ensure that the flatness of the conveyor belt surface is not affected by impurities.

The invention relates to a surface-mount circuit board piece module and a preparation method thereof, wherein the surface-mount circuit board piece module mainly comprises a circuit board, on which at least one electronic element is arranged, and a plurality of connectors; each connector comprises a first end part which is at least partially embedded in the circuit board, a connection part connected with the first end part, and a second end part formed by extending and bending the connection part relatively to one end of the first end part; and the surface of the second end part is stuck on asystem circuit board so that the electronic element on the circuit board is electrically connected with the system circuit board through the connectors. The surface-mount circuit board piece module utilizes the surfaces of the bent second end parts of the connection parts to be mounted on the system circuit board so as to avoid various inconveniences caused by the arrangement of the system circuit board through the interposition technology.

The invention aims to provide a spray head of an MOCVD (metal organic chemical vapor deposition) equipment reactor and a connection structure thereof so as to reduce the adverse influence of welding a bottom layer and a middle layer on a bottom surface. The spray head comprises a spray component and a top cover component, wherein the top cover component comprises a top cover; the spray component comprises a bottom layer, a middle layer and a top layer which are connected together; a cooling water channel and a cooling water cavity are formed between the bottom layer and the middle layer; a V-group gas cavity is formed between the middle layer and the top layer; a III-group cavity is formed between the top layer and the top cover; the bottom layer is an inward-concave integral member which is provided with a bottom wall and a corral side wall protruding from the bottom; and the outer side surface of the middle layer is welded with the inner side surface of the corral side wall of the bottom layer.

The invention belongs to the technical field of building construction, and specifically relates to a construction method for surface reinforcement treatment after pouring of building foundations, which is completed by mechanical cooperation of surface reinforcement treatment after pouring of building foundations, including the following steps: Step 1, construction preparation: prepare concrete, Move the machine to the top of the crack through the rollers, adjust the position of the machine so that the guide rod is parallel to the crack; Step 2, Drill the crack: Drill the crack through the drilling mechanism, and drive the drilling mechanism along the Move along the crack so that the crack becomes a V-shaped groove; Step 3: Fill the concrete: Send the concrete into the V-shaped groove through the trowel and smooth the filled concrete surface so that the repaired surface is flush with the foundation . The cracks can be fully filled when the surface reinforcement treatment machine for building foundation pouring of the present invention is used to fill the cracks, so as to ensure that there will be no gaps inside the cracks and improve building safety.
