The invention relates to a horizontal electroless nickel / immersion gold assembly line and an electroless nickel / immersion gold method. The horizontal electroless nickel / immersion gold assembly line comprises an automatic plate placing machine, a first micro-etching bath, a first rinsing bath set, a sand blasting machine, a second rinsing bath set, an oil removing bath set, a third rinsing bath set, a second micro-etching bath, a fourth rinsing bath set, a pre-soaking bath, an activated bath set, a fifth rinsing bath set, a pickling bath, a sixth rinsing bath set, a first surface treatment system, a seventh rinsing bath set, a second surface treatment system, a gold recovery bath, an eighth rinsing bath set, an operation station, a ninth rinsing bath set, a blowing-drying bath set, an automatic plate collecting machine and a conveying mechanism which are sequentially arranged. The horizontal electroless nickel / immersion gold assembly line has the effects of being short, suitable for installation and use in general small factories, high in electroless nickel / immersion gold efficiency and high in electroless nickel / immersion gold quality.

The invention relates to a powder cleaning-free gluing production method of laminated glass, which comprises the following steps: S1, preparing a solution of silica powder with silica powder and water and filtering the solution; S2, spraying silica powder solution on the air surface of outer plate glass and drying sprayed solution to obtain an uniform and thin silica powder layer; S3, matching the outer plate glass processed by the step S2 with inner plate glass; S4, carrying out hot bending of the glass processed by the step S3; and S5, putting a glue sheet between the two pieces of glass processed by the step S4 directly to carry out gluing. The laminated glass does not need to be cleaned in the process of the gluing; and the thin silica powder layer is absorbed by the glue sheet in thehigh-pressure process without influencing the light transmittance of the glass and can overcome the defect of cleaning the silica powder by the water in the prior art. The method at least has the advantages that: because the laminated glass is not needed to be cleaned by the water, sheet washing machines are saved and the obvious effects of energy conservation and consumption reduction are achieved; and the glass is not cleaned by the water, the existence of water stains between the glass are avoided, and problems of the quality, such as degumming, bubbles and the like are prevented.

The invention discloses a blurred vision preventing windscreen wiper which comprises a motor, a speed reducer, a four-bar mechanism, a water-wiping arm and a water-wiping slice, wherein the horizontal section of the water-wiping slice comprises three layers, namely, a first brush layer, a spongy layer and a second brush layer; an extruding structure is respectively connected with each of the two sides of the water-wiping arm; a first motor is fixedly arranged on the upper surface of the water-wiping arm; the extruding structure comprises a first guide rail, a second guide rail, a slide rod, a bracket, an extruding plate, a hauling cable and a return spring. The windscreen wiper further comprises a control structure, wherein the control structure comprises a button switch and an operation rod. The first motor is connected with a power supply through the button switch, the reasonable design of the windscreen wiper is realized, the glass surface is difficult to be blurred in the use process, the water spots are difficult to generate, the observation vision of the driver is not influenced and the technical effect of eliminating potential safety hazard is achieved.

The invention relates to a liquid crystal display, a liquid crystal display substrate and a formation method thereof. The method for forming the liquid crystal display substrate comprises the following steps: forming a gate metal layer in a short-circuiting bar area and a pad area on a substrate and forming a gate electrode in a pixel unit area; sequentially forming a gate electrode insulation layer and an amorphous silicon composite layer which cover the gate metal layer and the gate electrode on the substrate; etching the amorphous silicon composite layer and the gate electrode insulation layer in the short-circuiting bar area and the pad area until the gate metal layer is exposed to form a short-circuiting bar area contact hole and a pad area contact hole; etching the amorphous silicon composite layer and reserving the amorphous silicon composite layer at a position corresponding to the gate electrode in the pixel unit area; forming a source / drain electrode metal layer on the gate electrode and the amorphous silicon composite layer and in the short-circuiting bar area contact hole and the pad area contact hole; and etching the source / drain electrode metal layer to form a source / drain electrode and a conducting channel in the pixel unit area and electrically connect the gate electrode metal layer with the source / drain electrode metal layer in the short-circuiting bar area. The liquid crystal display and the liquid crystal display substrate and the formation method thereof improve the reliability of a device and the efficiency of product quality analysis.
