摘要
A component mounting system includes a board transport line for transporting a board from an upstream to a downstream and a work station disposed in the board transport line and performing component mounting work. The board transport line transports a board introduced in the downstream of the work station to the work station, and transports the board from the work station to the downstream when mounting of a component on the board is completed in the work station.

The present disclosure relates to a component mounting system that manufactures a mounting board in which a component is mounted on a board, a component mounting device used in the component mounting system, and a board transport method in the component mounting system.
In a component mounting system that manufactures a mounting board in which a component is mounted on a board, board transport conveyors such as a screen printing device, a component mounting device, and a reflow device are connected to form a board transport line (for example, Japanese Patent Unexamined Publication No. 2013-214588). In recent years, a configuration has been used in which an inspection device is disposed between the component mounting device and the reflow device, a component placing state on a board before reflow is inspected to perform feedback to the component mounting device.

What is claimed is:1. A component mounting system comprising:a board transport line configured to transport a board from an upstream side to a downstream side; and a plurality of work stations disposed in the board transport line and configured to perform component mounting on the board, wherein the board transport line is configured to:transport a board from the downstream side to a work station in the upstream side in a first reverse transportation mode; and transport the board from the work station to the downstream side in a normal transportation mode when the mounting of a component on the board is completed in the work station, wherein when mounting of the component is completed in the work station, the first reverse transportation mode is automatically switched to the normal transportation mode. 2. The component mounting system of claim 1 ,wherein the board transport line is configured to prohibit another board from being carried into the work station from the upstream side until the board in the downstream side reaches the work station. 3. The component mounting system of claim 2 ,wherein the board transport line is configured to enable the other board to be carried into the work station from the upstream side when the board is carried away from the work station after the mounting of the component was completed. 4. A component mounting device comprising:a board transporter constituting a board transport line for transporting a board from an upstream side to a downstream side; and a component mounting head configure to mount a component onto the board in a work station in the middle of the board transport line, wherein the board transporter comprises:a first operation mode in which a board received from the upstream side is transported to the work station and the board is transported in the downstream side when mounting of the component on the board is completed in the work station, and a second operation mode in which a board in the downstream side is transported to the work station in the upstream side, wherein when mounting of the component is completed in the work station, the first reverse transportation mode is automatically switched to the normal transportation mode. 5. The component mounting device of claim 4 ,wherein the board transporter is configured to prohibit another board from being carried into the work station from the upstream side until the board in the work station is transported to the downstream side according to the second operation mode. 6. The component mounting device of claim 4 ,wherein the board transporter is configured to transport, to the downstream side, the board which was carried into the work station according to the second operation mode and on which the mounting of the component has been completed. 7. The component mounting device of claim 6 ,wherein the board transporter is switched to the first operation mode after the board was carried into the work station according to the second operation mode, and is configured to transport, to the downstream side, the board on which the mounting of the component is completed according to the first operation mode. 8. The component mounting device of claim 4 ,wherein the board transporter further has a third operation mode in which a board in the downstream side is transported to the upstream side. 9. A board transport method in a component mounting device including a board transporter constituting a board transport line for transporting a board from an upstream side to a downstream side, and a component mounting head mounting a component on the board in a work station in the middle of the board transport line, the method comprising:transporting a board in the downstream side to a work station in the upstream side by the board transporter in a reverse transportation mode; transporting the board toward a stop position which is set in the work station in the upstream side by the board transporter; when the board overpasses the stop position, transporting the board toward the downstream side and stopping the board at the stop position by the board transporter; and transporting the board from the work station to the downstream side in a normal mode when the mounting of a component on the board is completed in the work station in a normal transportation mode, wherein when mounting of the component is completed in the work station, the first reverse transportation mode is automatically switched to the normal transportation mode. 10. A component mounting system comprising:a board transport line configured to transport a board from an upstream side to a downstream side; and a plurality of work stations disposed in the board transport line and configured to perform component mounting on the board, wherein the board transport line is configured to:transport a board from the downstream side to a work station in the upstream side in a first reverse transportation mode; and transport the board from the work station to the downstream side in a normal transportation mode when the mounting of a component on the board is completed in the work station, wherein the board transport line comprises a first component mounting device and a second component mounting device aligned in an order, and the board transport line is further configured to transport the board from the downstream side to the first component mounting device in the upstream side by passing through the second component mounting device in a second reverse transporting mode.
