LIQUID DISCHARGE APPARATUS, LIQUID DISCHARGE METHOD, MOLDING APPARATUS, AND ARTICLE MANUFACTURING METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 17871822 titled 'LIQUID DISCHARGE APPARATUS, LIQUID DISCHARGE METHOD, MOLDING APPARATUS, AND ARTICLE MANUFACTURING METHOD

Simplified Explanation

The liquid discharge apparatus described in this patent application includes a substrate stage that can move while holding a substrate, a discharge unit with nozzles for discharging a liquid, a control unit that controls the discharge unit, and a position acquisition unit that acquires the position of a movement target object at a specific timing.

• The control unit determines the timing for discharging the liquid based on the difference between the acquired position of the movement target object and the target position of the object at that timing.
• The apparatus can be used in various applications such as inkjet printing, coating, or cleaning processes where precise liquid discharge is required.
• The position acquisition unit ensures accurate positioning of the movement target object, allowing for precise control of the liquid discharge.
• The control unit's ability to adjust the discharge timing based on the difference in positions improves the accuracy and efficiency of the liquid discharge process.

Potential Applications

• Inkjet printing: The apparatus can be used in printers to precisely discharge ink onto substrates, enabling high-quality printing.
• Coating processes: It can be utilized in coating applications where precise liquid deposition is crucial, such as in the manufacturing of electronic components or optical films.
• Cleaning processes: The apparatus can be employed in cleaning systems to discharge cleaning agents accurately onto surfaces that require cleaning.

Problems Solved

• Inaccurate liquid discharge: The apparatus solves the problem of inaccurate liquid discharge by controlling the timing of the discharge based on the position of the movement target object.
• Inefficient liquid deposition: By adjusting the discharge timing, the apparatus ensures efficient and precise liquid deposition, reducing waste and improving overall process efficiency.

Benefits

• Improved accuracy: The control unit's ability to adjust the discharge timing based on position differences ensures precise liquid discharge, resulting in high-quality output.
• Enhanced efficiency: The apparatus optimizes the liquid discharge process, reducing waste and improving overall productivity.
• Versatile applications: The apparatus can be utilized in various industries and processes that require precise liquid discharge, providing flexibility and adaptability.

Original Abstract Submitted

A liquid discharge apparatus includes a substrate stage configured to move while holding a substrate, a discharge unit including nozzles for discharging a liquid, a control unit configured to control the discharge unit to discharge the liquid from the discharge unit, and a position acquisition unit configured to acquire a position of a movement target object at a predetermined timing while the substrate stage or the discharge unit is moved as the movement target object. The control unit controls a discharge timing for discharging the liquid from the discharge unit, based on a difference between the position of the movement target object acquired by the position acquisition unit at the predetermined timing and a target position of the movement target object at the predetermined timing.
