The invention discloses a mechanical device for removing floating matter, comprising a separator connected with a sodium metaaluminate dissolving kettle, a foam collector, a water circulation vacuum pump and a floating matter storage tank, the floating matter storage tank There is a groove on one side, and there are two horizontally arranged rotating shafts in the groove. The outer rotation of the two rotating shafts is fitted with the same cover plate, which is located on one side of the float storage tank, and the outer rotation of the two rotating shafts The suit has the same skateboard, the skateboard is movably installed in the groove, a through hole is opened on one side of the skateboard, and a mounting rod welded on one side of the skateboard is arranged above the through hole, and a first sealing gasket is fixed on the outer side of the mounting rod. The first sealing gasket matches with the through hole. The invention is reasonable in design, convenient in operation, high in practical performance, easy to release the fixation of the cover plate, and convenient to pull out the slide plate from the groove. Floats inside.

The invention relates to a high-precision chip welding method for an LED full-automatic crystal-bonding machine. By improving the crystal-bonding bracket and the bracket fixture, the loading process of the crystal-bonding bracket is greatly improved, which is convenient for the staff to quickly load, and at the same time facilitates the staff from the bracket. Take out the crystal-bonding bracket from the fixture, and the bracket fixture can be quickly released by setting the compression spring, which is convenient for the staff to take out the crystal-bonding bracket from the bracket fixture, and the dust-proof tape set at the notch of the T-shaped chute can Effectively protect the T-shaped chute, so that the inside of the T-shaped chute is not easy to be affected by external debris, and it is not easy to affect the normal sliding of the slider and the connecting column. Finally, for the bracket fixture, the design of the connecting base and the connecting rod is hard and soft. Under the premise of ensuring that the main rod of the bracket and the cup of the bracket are relatively stable, the upper part of the main rod of the bracket and the cup of the bracket can be displaced in a small range within a controllable range, which is convenient for the reinforcement of the die-bonding bracket.
