  • Patent number: 11525669
    Abstract: A laser projection module is provided. The laser projection module includes a substrate assembly, a lens barrel assembly, a light source, a diffractive optical element and a collimation element. The lens barrel assembly includes a lens barrel and a stop member connected to the lens barrel. The lens barrel is disposed on the substrate assembly and configured to define a receiving cavity together with the substrate assembly. The light source is disposed on the substrate assembly, accommodated in the receiving cavity, and configured to emit laser to the receiving cavity. The diffractive optical element and the collimation element are accommodated in the receiving cavity. The light source, the collimation element and the diffractive optical element are sequentially disposed in an optical path of the light source. The stop member is configured to prevent the diffractive optical element from moving in a light-emitting direction of the laser projection module.

  • Patent number: 11054334
    Abstract: A die casting machine melt leakage detecting device includes a pulling wire, multiple wire winding columns, a wire fixing member, an elastic wire connecting member and a trigger switch. The pulling wire is capable of withstanding temperature outside a mold during normal die casting and is melted and broken after making contact with molten metal. The multiple wire winding columns are arranged around the mold, an end of the pulling wire is connected with the wire fixing member, and another end of the pulling wire is sequentially wound around the wire winding columns and is connected with the elastic wire connecting member. The elastic wire connecting member is opposite to the trigger switch, the elastic wire connecting member is in a compressed or stretched state when the pulling wire is kept tensioned in the operating state.

  • Patent number: 10737885
    Abstract: Provided is an automatic compensation, balancing and tensioning conveying chain wherein the conveying chain can automatically adjust the guide rails to extend and retract and be automatically tensioned and balanced to avoid the influence on the conveying efficiency of the conveying chain due to the slack of the conveying chain. In addition, the guide rail position maintaining components provide a reverse compensation force to the telescopic guide rail when the guide rail pre-warning limiting switches are triggered, so as to reduce the imbalance of movements of the sliding trolleys and avoid a situation that the sliding trolley may trigger an extreme position signal in advance to cause a false alarm and stop the entire conveying chain, thereby guaranteeing a dynamic balance of two tensioning stations and completely eliminating an elasticity change of the chain.
