How to change the suction nozzle position of the head in the chip mounter

摘要

The present invention provides a chip mounter for mounting an electronic component in which a suction nozzle to be mounted on a test jig is changed to a mounting position in an arbitrary head, and then the suction nozzle position of one head is changed to automatically move the corresponding head to a specific station. The present invention relates to a method, in which the present invention initializes the control system when a mode signal for selecting an arbitrary head for mounting a test jig is input through a user interface means, and then drives a servo motor to clock or index an index. A first step of detecting an arbitrary head at a specific station among the plurality of stations by continuously rotating one step in the direction; A second process of driving a servo motor to move the arbitrary head clockwise by a predetermined pitch when the predetermined head is detected at the specific station and moving to the next station; A third step of checking whether the number of the suction nozzle at the mounting position of any head in the next station matches the number of the designated suction nozzle to which the test jig provided from the interface means is to be fitted; If the number of suction nozzles detected and the number of the designated suction nozzles coincide with each other as a result of the check in the third step, the servo motor is driven to rotate any head clockwise or counterclockwise to pre-set the predetermined jig for mounting the test jig. Moving to a station of the fourth step; If the number of the suction nozzle detected and the number of the designated suction nozzle do not match as a result of the check in the third step, the pulse motor is driven to change the designated suction nozzle in an arbitrary head to the mounting position, and then the servo motor is driven to The test jig can be removed from the position of the station that is convenient for replacement through the fifth process of rotating an arbitrary head whose position of the suction nozzle has been changed clockwise or counterclockwise to move to a predetermined station for mounting the test jig. By automatically changing the suction nozzle to be mounted to the convenient mounting position, the user can move the test jig to the pre-selected test jig mounting position. It can be mounted.
