By means of the conveying mechanism, balls before and after grinding can be independently conveyed, confusion of a feeding path and a recycling path is effectively prevented, the situation that the balls before and after grinding interfere with each other is avoided, meanwhile, the feeding and recycling processes do not need to be manually intervened, the ball machining continuity is guaranteed, and the machining efficiency is improved. And the ball machining efficiency is effectively improved, and the labor cost is further reduced.

This invention relates to a composite vibration-assisted flexible conformal polishing device for complex curved optical elements, comprising a gantry with a worktable positioned below it; a vertical vibration mechanism is positioned on the gantry facing the working bearing area to provide vertical vibration force; a flexible conformal polishing disk conformally and uniformly fits the optical element to its lower end; the optical element is located on a horizontal sliding vibration mechanism in the working bearing area, achieving short-distance reciprocating sliding vibration in the lateral direction; the short-distance reciprocating sliding vibration in the lateral direction and the vertical vibration combine to form a composite vibration. The vibration of the flexible conformal polishing disk in both the vertical and horizontal directions improves the material removal efficiency of the optical element and enhances the fit characteristics of the flexible conformal polishing disk to the complex curved optical element, thereby improving the smoothness of small-scale ripples. It can be used for rapid removal of defects remaining from previous processing during rough polishing, and can also be used to remove small-scale ripples after sub-aperture polishing.

The application belongs to the technical field of automobiles and discloses a front windshield lower decorative plate and an automobile, which comprise a front windshield lower decorative plate body and a side shielding plate which is detachably installed on the side of the front windshield lower decorative plate body and covers the exposed area of a sheet metal gutter assembly. The side shielding plate comprises a hard rubber part and a soft rubber part. The hard rubber part is shaped according to the contour of the exposed area of the sheet metal, and the soft rubber part is arranged on the circumferential edge of the hard rubber part and is attached to the adjacent automobile body part. The application aims to solve the problems of insufficient shielding caused by the exposed joint of the front windshield lower decorative plate and the sheet metal gutter assembly and poor sealing caused by the direct exposure of the joint gap between the two, improve the overall appearance of the front compartment area, and prevent dust and water vapor from the outside from entering the interior of the front compartment through the gap.

The utility model relates to rust cleaning brush head technical field, concretely is a rust cleaning brush head of rust cleaning machine, including power flow guide subassembly, floating brush head subassembly, the top fixed mounting of power flow guide subassembly has floating brush head subassembly, wherein, power flow guide subassembly includes connecting rod, the bottom fixed connection of connecting rod has connecting rod tail, the upper portion outside fixed connection of connecting rod has six groups of fan blade, the left top of connecting rod is provided with bolt, the right side of bolt is provided with nut. By being provided with spring in each bundle brush base bottom, constitute floating mechanism, make bundle brush can carry out local fine adjustment. The design makes floating brush head subassembly when contact uneven, with the surface of weld or crater, each group bundle brush can independently stretch according to surface profile, always keep optimum contact pressure and degree of adhesion, effectively eliminate the cleaning dead angle, significantly improved the rust cleaning uniformity and effect to uneven surface.

The utility model discloses a kind of unstacking devices, comprising: lifting mechanism, for placing by material package palletizing formed palletizing object, and can lift the palletizing object;Sucker mechanism is located above lifting mechanism;The sucker mechanism includes: suction cup, for sucking material package;Three-dimensional movement module, for driving suction cup to move in three-dimensional direction, to make suction cup move to palletizing object place and suck the material package, and move the material package sucked to discharge station, to make the material package enter material conveying line via the discharge station place.This utility model lifts palletizing object by lifting mechanism layer by layer, sucker mechanism is located above lifting mechanism, and the uppermost layer of palletizing object is guaranteed in fixed position by the lifting of lifting mechanism, reduces the movement stroke of suction cup under suction, improves unstacking efficiency.In addition, floating module is further configured above suction cup, when suction cup contacts material package, the inclination of suction cup can be adjusted according to the uneven shape of material package, so that suction cup is more suitable for adhering material package surface.

This invention belongs to the field of screen bonding technology and discloses a full bonding method using liquid adhesive. The full bonding method using liquid adhesive includes the following steps: placing a lower substrate horizontally; applying liquid adhesive to the left side of the lower substrate; aligning the upper substrate and the lower substrate horizontally, such that the right side of the upper substrate is aligned with the left side of the lower substrate in the front-back direction, while simultaneously ensuring that the projection of the right side of the upper substrate in the vertical direction falls within the liquid adhesive application area; moving the upper substrate downwards, so that a portion of the upper substrate is immersed in the liquid adhesive, while the lower surface of the upper substrate is spaced apart from the upper surface of the lower substrate; moving the upper substrate to the right until the right side of the upper substrate coincides with the right side of the lower substrate; moving the upper substrate downwards until the vertical distance between the upper and lower substrates is a preset adhesive layer thickness. This method is suitable for bonding substrates with very thin adhesive layers, results in minimal adhesive overflow, minimal liquid adhesive waste, and good bonding quality.
