Knee pad forming device capable of eliminating bubbles for AR equipment

Abstract

The invention relates to the field of AR equipment, in particular to a knee pad forming device capable of eliminating bubbles for AR equipment. The technical purpose to be achieved by the invention is to provide a knee pad forming device capable of eliminating bubbles for AR equipment. According to the technical scheme, the knee pad forming device capable of eliminating bubbles for AR equipment comprises a chassis, a transportation assembly, an upper silica gel assembly, a forming assembly and the like; and the upper silica gel assembly is connected with the forming assembly. When the knee pad forming device is used, silica gel is automatically injected into a groove of an EVA composite shell layer by layer, so that the silica gel has sufficient time to flow into a small groove in the EVA composite shell; meanwhile, each layer of silica gel is circular, so that the silica gel is uniformly distributed; meanwhile, the upper surface of the silica gel layer is flat through vibration, and glue marks on the inner wall of the groove are removed completely; and the groove of the EVA composite shell is automatically extended and supplemented with polyurethane foaming colloid for forming operation, so that the notch phenomenon of a formed sponge body is avoided.

Description

technical field [0001] The invention relates to the field of AR equipment, in particular to a knee pad forming device for AR equipment that can eliminate air bubbles. Background technique [0002] AR technology is a technology that ingeniously integrates virtual information with the real world. One of the AR devices needs to wear knee pads during use to enhance safety. The knee pads are bowl-shaped as a whole. Inject an appropriate amount of silica gel into the groove of the EVA composite shell and dry it, then inject an appropriate amount of polyurethane foam colloid on the top of the silicone layer, and then expand it into a bowl-shaped sponge through a shaping mold and heating, and the bottom of the EVA composite shell is provided with some decorative Protrusion, that is, there are some small grooves at the bottom of the groove of the EVA composite shell. When the silica gel is directly poured into the groove of the EVA composite shell, the gas in the small groove cannot ...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the existing device when producing this kind of knee pads, since the bottom of the EVA composite shell is provided with some decorative protrusions, that is, there are some small grooves at the bottom of the groove of the EVA composite shell, directly pour the silica gel into the groove of the EVA composite shell At this time, the gas in the small groove cannot be discharged in time, resulting in air bubbles after the silica gel dries. In addition, when the existing device levels the upper surface of the silica gel layer, the upper layer of silica gel moves, leaving glue marks on the inner wall of the groove of the EVA composite shell. , In addition, when the existing device is used for molding operations, the gap between the inner extension of the EVA composite shell and the shaping mold is relatively large, and the polyurethane foam colloid for the extension is relatively small, so that the sponge body has a gap phenomenon after molding, which needs to be solved Technical problem: Provide a knee pad forming device for AR equipment that can eliminate air bubbles
