Embodiment 1

[0107] (coating device)

[0108] Such as Figure 7 As shown, the coating device 701 of this embodiment includes an X driving mechanism 702, a Y driving mechanism 703, a Z driving mechanism 704, a discharge device 705, and a control unit 709 for controlling these operations.

[0109] A Z drive mechanism 704 is provided on the X drive mechanism 702 . A workbench 710 on which an object to be coated 708 is placed is provided on the Y drive mechanism 703 . The discharge device 705 includes a storage container 706 capable of storing a liquid material, and a nozzle 707 that discharges the liquid material from the tip thereof. Although the combination of the storage container 706 and the nozzle 707 is shown as the discharge device 705, it is not limited thereto, and any device may be used as long as it has the nozzle 707.

[0110] The adjustment mechanism 301 is arranged between the Z drive mechanism 704 and the ejection device 705 . At this time, the adjustment mechanism 301, the...

Embodiment 2

[0114] (Example of a configuration in which multiple holes are provided in the positioning member)

[0115] In Example 1, although the nozzle fitting hole 104 of the positioning member 101 is one, a plurality of holes ( 805 to 809 ) with different inner diameters may be provided in order to accommodate a plurality of types of nozzle diameters assumed to be used. Figure 8 An example of this configuration is shown.

[0116] Figure 8 The illustrated positioning member 801 is composed of two members, a fitting member 802 and an abutting member 803, as in the first embodiment. In the fitting member 802, a hole 805 for fitting the most frequently used nozzle is provided at the center. Also, holes (806, 807) having a larger diameter than the central hole 805 are provided on the right side thereof, and holes (808, 809) having a smaller diameter than the central hole 805 are provided on the left side. The same tapered portion 810 as above is provided in each hole (805-809) in acco...

Abstract

The present invention provides a nozzle position correcting device which, when a liquid material is applied to a surface of a workpiece (708) by moving relative to each other by drive mechanisms (702, 703, 704) a nozzle (707) for discharging a liquid material and the workpiece (708) placed on a table (710), corrects the position of the nozzle. The device is provided with adjusting sections (304, 305, 306) for adjusting the position of the nozzle relative to the drive mechanisms, and also with a positioning member (101) having a nozzle insertion hole (104) through which the nozzle is inserted and also having a contact surface (106) making contact with the tip of the nozzle inserted through the nozzle insertion hole. The position of the nozzle can be mechanically adjusted by using a simple structure without requiring special equipment such as a camera and a sensor.

Description

technical field [0001] The present invention relates to a nozzle position correction mechanism and a coating device equipped with the mechanism. More specifically, it relates to the relative movement of a nozzle for ejecting a liquid material and a workpiece placed on a workbench by a drive mechanism. It is also a nozzle position correction mechanism that can correct the deviation of the nozzle position caused by maintenance work when coating liquid material on the workpiece surface. Background technique [0002] When performing work such as replenishment or maintenance of the liquid material, the discharge device including the nozzle or the storage container is detached from the coating device. And, when the replenishment or maintenance of the liquid material is completed, the ejection device is attached to the coating device. At this time, the position of the discharge port formed at the tip of the nozzle included in the discharge device is mostly deviated from the positi...
