Embodiment Construction

[0022] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0023] figure 1 In , the configuration of a control system of a component mounting machine that mounts electronic components on a circuit board is shown as a block diagram. In the component mounting machine, an X-axis servo motor 2 and a Y-axis servo motor 3 are provided, and encoders 6 and 7 for detecting respective rotational speeds and rotational positions are attached to these motors. When the X-axis servomotor 2 is driven by the instruction of the controller 1 composed of CPU, RAM, ROM, etc., the moving head unit 10 moves in the X-axis direction, and when the Y-axis servomotor 3 is driven, the moving head unit 10 Move along the Y axis.

[0024] Further, the moving head unit 10 is provided with a nozzle holding member 12 and a suction nozzle 13 held on the central axis thereof. The nozzle holding part 12 and the suction nozzle 13 can be rotated around ...

Abstract

The present invention provides a parts assembling machine and self_diagnosing method thereof. To provide constitution which can judge surely abnormality which occurs in connection with the drive portion for moving a head unit in a component arrangement machine. The drive mechanism such as servo motors (2-5) moves a movement (head unit 10, suction nozzle 13) in the directions of X-axis, Y-axis, Z-axis and R-axis. When the drive mechanism is normal and the movement is moved along a prescribed movement stroke, control deviation such as velocity deviation and position deviation which are generated in a prescribed movement region is stored in a controller (1) as the default of the control deviation. When self-diagnosis of each drive mechanism is performed, the control deviation which is generated in the movement region when the movement (10) is moved along the movement stroke by each of the drive mechanism is compared with the stored default. Based on the comparison result, abnormality of the drive mechanism is judged.

Description

technical field [0001] The present invention relates to a component mounting machine and a self-diagnosis method thereof, and particularly relates to a component mounting machine which uses a moving head unit having a suction nozzle to absorb electronic components such as ICs, moves the moving head unit to a circuit board, and mounts the components on the circuit board and its self-diagnosis method. Background technique [0002] Patent Document 1: JP-A-6-276000 (paragraphs [0020] to [0030], Figure 6 ~ Figure 9 ). [0003] Conventionally, for example, the above-mentioned patent document 1 and the like have known a structure for self-diagnosing the location of a failure in the above-mentioned component mounting machine or a so-called chip mounter. Patent Document 1 describes a method of diagnosing whether a drive control system that drives a DC servo motor 6 that moves a table of a chip mounter in the X and Y directions is good. Thus, first, a pulse indicating the amount of...
