The invention relates to a filler dripping device which comprises an accommodating tube, a magnetic piece, a first coil, a second coil and a control structure, wherein the accommodating tube is used for accommodating a filler; a filler outlet is formed in one end of the accommodating tube; the magnetic piece is accommodated in the filler of the accommodating tube; under the first state, the magnetic piece leaves the filler outlet and moves in the length direction of the accommodating tube to a first position; under the second state, the magnetic piece moves reversely from the first position toblock off the filler outlet; the first coil and the second coil are twined on the peripheral surface of the accommodating tube and are arranged at a preset distance in the length direction of the accommodating tube; the first coil is close to the filler outlet; the control structure is used for controlling the parameters of a magnetic field generated by the first coil and the second coil to switch over the magnetic piece between the first state and the second state; and the parameters comprise whether the first coil and the second coil are electrified or not, and / or the interval of the electrifying and outage switching time, and / or the current size of the first coil and the second coil under the electrifying state.
Description
technical field [0001] The invention relates to the technical field of display product production, in particular to a filler dropping device. Background technique [0002] As a new lighting and display technology, Organic Light-Emitting Device (OLED) has its unique advantages and has been widely used. Improving the performance of OLED devices is a subject to be studied at present. The effect of the encapsulation process has an important impact on the life of the OLED device, and the stability of the encapsulation glue affects the result of the encapsulation process to a large extent. [0003] The traditional filler dripping device is mainly composed of an electromagnet, a liquid holding tube, and a striker. The electromagnet provides a magnetic field. To hit the outlet of the liquid tube to control its blockage and then control the dripping of the filler. The dripping amount is mainly controlled by the falling height of the firing pin and the switching time of the firing p...
