The present invention provides a solder ball separation device, including a hopper for storing solder balls, a machine platform for supporting the hopper, a cover body covering the hopper, and a material transfer mechanism for removing solder balls from the hopper, wherein the hopper is located in the cover body, and the cover body is provided with a material taking port for a suction head of a manipulator to extend into the cover body; the material transfer mechanism includes a material transfer column arranged in the hopper and a first linear drive mechanism for driving the material transfer column to transfer the solder balls to the material taking port position for the suction head to absorb, the first linear drive mechanism is arranged on the machine platform, and the material transfer column is connected to the first linear drive mechanism. When in use, the first linear drive mechanism drives the material transfer column to transfer the solder balls in the hopper to the material taking port position on the cover body, so that the solder balls in the hopper can be automatically separated quickly and efficiently, and there will be no ball jamming. The solder ball separation efficiency is high, and it can also be applicable to the separation of solder balls of different sizes, without the need to configure a variety of different solder ball separation devices for solder balls of different sizes.

This invention discloses a connector and a detachable amphibious robot, comprising: a first mounting base and a second mounting base, wherein the first mounting base is provided with a guide rail, and the second mounting base is provided with a guide block that matches the guide rail; and a rotating disk, which is rotatably disposed at the top of the first mounting base, and the rotating disk is provided with a plurality of stop blocks, with a gap between adjacent two stop blocks, and the stop blocks are used to prevent the guide block from disengaging from the top of the guide rail; wherein, the rotating disk is used to rotate under pressure to a first position and a second position when the second mounting base moves up and down relative to the first mounting base, and in the first position, the guide block matches or disengages from the guide rail through the gap, and in the second position, the stop blocks correspondingly prevent the guide block from disengaging from the guide rail.

The invention belongs to the technical field of super-hydrophobic fabrics. The invention provides a preparation method of a wear-resistant corrosion-resistant super-hydrophobic fabric. The method comprises the following steps: S1, immersing a fabric into a mixed solution of a citric acid solution and a copper nitrate solution, and stirring; s2, adding a sodium sulfide solution into the mixed solution with the fabric, and stirring; s3, continuously adding the solution containing the low-surface-energy substance and stirring; s4, taking out the fabric, washing and drying to obtain the wear-resistant and corrosion-resistant super-hydrophobic fabric. The preparation method is economical, environmentally friendly and easy to operate, the surface of the super-hydrophobic cotton fabric prepared through the preparation method has excellent hydrophobicity and lipophilicity, and rapid and efficient oil-water separation and cyclic separation can be achieved; and the coating also has good self-cleaning property, wear resistance and corrosion resistance, and can be recycled for a long time.
