PURPOSE: An apparatus for calibrating the position of a dispenser needle is provided to improve convenience of using a potting system without an additional calculation or input of a user by automatically calculating the coating pattern of a programmed semiconductor chip with respect to a dispenser needle while checking the semiconductor chip with respect to a CCD(charge coupled device) camera. CONSTITUTION: Encapsulant is formed on a semiconductor chip on a semiconductor film by using a dispenser(12). The dispenser is installed in a robot(10). The first CCD camera(16) is installed in a side of the robot. The second CCD camera(18) checks and transmits the image picture of the first CCD camera and the dispenser needle. A vision board(22) receives the image signal of the first and second CCD cameras and converts the image signal into a digital signal. A main computer(24) receives the digital signal transmitted from the vision board so as to perform an operation, an input/output control and a robot control, including an image processing algorithm operator(25), a system I/O(input/output) control(26) and an upper controller(27). A TSP(touch screen panel)(20) displays the signal transmitted from the main computer on a screen or transmits an input signal touched by a user to the main computer, connected to the main computer.
