The invention discloses a six-degree-freedom entire movement restrained system of a floating platform. The six-degree-freedom entire movement restrained system of the floating platform comprises a rotating body set composed of an adjustable latticed tuning liquid column damper and a hollow rotating body with an opening at the bottom which is immerged into water; the adjustable latticed tuning liquid column damper is arranged on a certain layer of deck surface, above the water surface, in the floating platform, an upright pillar is arranged below the deck, a caisson connecting upright pillar is arranged at the bottom of the upright pillar, the top portion of the hollow rotating body with an opening at the bottom which is immerged into water is connected with a rotating arm of a sliding groove, the rotating arm of the sliding groove is provided with the sliding groove for sliding of the rotating body, one end of the rotating arm of the sliding groove is provided with a rotating shaft, and the rotating arm of the sliding groove is arranged on the upright pillar through the rotating shaft. According to the six-degree-freedom entire movement restrained system of the floating platform, the operating cost of a floating platform vibration damper is low, the operation is simple, and the use, installation, disassembly and moving are very convenient; the cost and operating expense are low, and the floating platform vibration damper is suitable for various floating platforms.

The invention relates to a liquid floating spray tray for a COF wet process. The liquid floating spray tray comprises a sealed cavity, the side wall of the sealed cavity is provided with a water inletand a water outlet hole, and a developing solution enters the sealed cavity through the water inlet and is flushed out in a liquid column node through the water outlet hole to jack a COF product located at the upper portion of the water outlet hole and perform developing effect on the COF product. In the structure mentioned above, the liquid column formed by the developing liquid is configured todirectly support the COF product with no need for other structures to be in contact with the COF product for support so as to avoid usage of a traditional segment gap roller and so as not to need theside design for the segment gap roller, and the structure is simple; and moreover, it is avoided that the structure having a support effect is in contact with the COF product to pollute or damage a dry film or a circuit of the COF product so as to improve the COF product quality.
