A component mounting machine, including a component transfer device, having a component mounting tool configured to collect and mount a component, a mounting head configured to hold the component mounting tool, and a head driving mechanism configured to horizontally drive the mounting head, which performs a mounting work of mounting the component collected from a component supply device on a predetermined coordinate position of a board carried in and positioned by a board conveyance device, and a control device configured to control the mounting work, and configured to implement a thermal correction process for reducing an influence on mounting accuracy of the component, of which influence being caused by thermal deformation due to a temperature change in at least one of the head driving mechanism and the mounting head.

Component mounting machine

A mounting device for executing a mounting process of mounting a component on a board includes: a mounting head that includes at least one pickup section for picking up the component and moves the picked up component; a storage section configured to store at least a first correction value determined at a first position on XYZ axes on which the mounting head works and a second correction value determined at a second position different from the first position; and a control section configured to execute the mounting process by using the first correction value and/or the second correction value stored in the storage section.

Mounting device and mounting method

Each of multiple component mounting machines constituting a component mounting line is configured to switch between a production mode in which a component is mounted on a circuit board that has been conveyed in and then conveyed out, a mounting accuracy measurement mode in which a mounting accuracy measurement component is mounted at a predetermined position on a mounting accuracy measurement board and the mounting accuracy is measured, and a pass mode in which a component is conveyed out without being mounted on the board conveyed in. When the control mode of two or more component mounters among the multiple component mounting machines is the mounting accuracy measurement mode, the mounting accuracy is measured by conveying the mounting accuracy measurement board along the board conveyance path, and the two or more component mounting machines sequentially use the mounting accuracy measurement board to measure the mounting accuracy.

Mounting accuracy measurement system for component mounting line, and mounting accuracy measurement method

In a control device which outputs control instructions at a constant cycle to each of a plurality of networks for executing a predetermined process according to the control instructions, a time (a required time) from when the control instruction is output to each of the plurality of networks until the predetermined process is executed is acquired for each of the plurality of networks. Among the plurality of required times, a difference (a shift time) between a short required time (required time of mounting head) and a long required time (required time of moving device) is calculated. When the shift time has elapsed after outputting the control instruction to the network of the moving device, the control instruction is output to the network of the mounting head.

Control device with constant cycle for a plurality of networks

A controller capable of transmitting and receiving an input signal from a drive circuit corresponding to a moving device, a mounting head, or the like of an electronic component mounting machine or an output signal to the drive circuit for each predetermined period (A/2), in which the controller computes an output signal based on an input signal which is received before the predetermined period, stores the output signal for a time greater than or equal to the predetermined period, and subsequently transmits the output signal to the drive circuit. It becomes possible to set a time (a delay time) from when an input signal is output until an output signal reaches a drive circuit to an arbitrary length by adjusting the storage time.
