摘要： A reciprocating glue dispenser dispensing switch includes a switching device main body, a needle holding base, a sliding wear-resistant plate, and a driving device. The switching device main body is equipped with a double liquid inlet, the needle holding base is equipped with a mixed glue outlet, the sliding wear-resistant plate is installed between the switching device main body and the needle holding base, and the sliding wear-resistant plate is equipped with a sliding wear-resistant plate opening. The driving device is utilized to move the sliding wear-resistant plate. A mixed double-liquid glue passes through the double liquid inlet, the sliding wear-resistant plate opening and the glue outlet to dispense a mixed double-liquid glue while the double liquid inlet, the sliding wear-resistant plate opening and the glue outlet are overlapped. In addition, a double liquid dispensing equipment is also disclosed herein.

摘要： The present invention discloses a fluid control structure of a dispensing apparatus, comprising: a dispensing unit, a fluid supply unit, and a control unit. The present invention is characterized by its dispensing apparatus which includes a needle head, a thimble, and a valve body, wherein the valve body is provided with an accommodating space for accommodating the needle head and the thimble. The needle head is being formed a hollow space, and the space is tapered towards the direction of a nozzle, the nozzle disposed at one end of the needle head; the thimble is moved up and down along the valve body, having the same tapered as the inner diameter of the needle head. The fluid control structure of the dispensing apparatus of the present invention is to solve the shortcoming of prior art that the residual pressure in the dispensing process cause the fluid being dropped or leaked on the dispensing surface.

摘要： A dual-valve automatic calibration system comprises a primary positioner, a first secondary positioner and a second secondary positioner: the first secondary positioner and the second secondary positioner are connected with a first fluid coating unit and a second fluid coating unit, respectively; the primary positioner comprises a primary X-axis positioner and a primary Y-axis positioner; both the first secondary positioner and the second secondary positioner are connected with the primary X-axis positioner. In contrast to the prior art that a secondary positioner is installed on a primary Z-axis positioner, a dual-valve automatic calibration system contributes to promotion of positioning precision on the Z-axis and reduction of a burden imposed on the Z-axis.

摘要： A mass transferring system and the method thereof are provided. The system includes two platforms and a plurality of picking and placing units. When the mass transferring process is performed for one of the substrates, the replacing process and the aligning process are simultaneously executed for another one of the substrates, such that the mass transferring process and the replacing process can be performed at the same time. Compared with the conventional mass transferring processes, the efficiency of the mass transferring system and the method thereof according to the present invention can be increased by 90%.
