Description

  The present invention has a component supply stage in which a large number of tape-type component supply devices can be arranged in advance instead of a component supply stage in which a large number of tape-type component supply devices are arranged in the component mounting device, and is connected to the component mounting device The present invention relates to a part supply stage carriage for a mold.

  Conventionally, in a board production line, a chip unit electronic component (hereinafter simply referred to as a component) is automatically mounted on a printed circuit board (hereinafter simply referred to as a substrate) that is carried into the apparatus from the upstream side of the line. There are parts mounting equipment that produces

  FIG. 5 (a) is an external perspective view of such a component mounting apparatus, and FIG. 5 (b) is a perspective view schematically showing an internal configuration by removing the upper and lower protective covers. As shown in FIGS. 2A and 2B, the component mounting apparatus 1 notifies the operating state both on the front and rear of the ceiling cover, on the monitor apparatus 2 composed of a CRT display, and on the left and right on the ceiling cover, respectively. An alarm lamp 3 is provided. An operation input display device 5 is provided on the front and rear surfaces of the upper protective cover 4.

  A pair of parallel and fixed substrate guide rails 7 fixed and movable at the center are placed on the lower base 6 in the direction of conveyance of the substrate 47 shown in FIG. (Upper left direction) extending horizontally. A loop-shaped transport belt (conveyor belt) in contact with the lower part of the board guide rails 7 and not shown in the drawing is disposed so as to be able to run. The conveyor belt carries a new board 8 into the apparatus, stops it during component mounting, and unloads it downstream of the line after component mounting.

  Component supply stages 8 are formed on the front and rear sides of the base 6, respectively (the component supply stage 8 at the rear portion in the upper right direction in the figure is hidden behind and cannot be seen in the figure (a). In FIG. 5 (b), the rear part supply stage 8 is not shown). On the component supply stage 8, a large number of tape-type component supply devices 10, 50 to 70, are arranged. The tape-type component supply device 10 is detachably mounted at its rear end with a tape reel 11 on which a tape containing components is attached.

  In addition, above the base 6, the two vertical fishing-type Y-axis rails 12 that are divided into the left and right sides (X-axis direction) of the main body frame and are fixed to the main body frame, and the two Y-axis rails 12 are passed. Two X-axis rails 13 that are slidably supported are arranged. A single work head 14 is suspended on each of the X-axis rails 13 so as to be slidable in the X-axis direction along the X-axis rails 13. Two mounting heads 15 are disposed on each of the work heads 14. ing. A suction nozzle 16 is detachably attached to the tip of the mounting head 15.

  The mounting head 15 of the work head 14 sucks a component supplied from the tape-type component supply device 10 with a suction nozzle 16, recognizes an image with a component recognition camera 17, corrects the position, and then fixes the component on a predetermined substrate 8. Installed at the mounting position.

  By the way, setting up and arranging a large number of tape-type component supply devices one by one on the component supply stage of the component mounting device in the setup work before the start of production by the board production line is extremely troublesome. Since the substrate production line must be stopped during this period, the overall work efficiency is greatly reduced. In addition, in recent years, the production of small-sized units for board units has increased, and it has become necessary to switch the production model of board units in a short period of time, and it has become increasingly troublesome in the setup work.

  In addition, as portable small electronic devices become widespread, the substrate incorporated in the electronic device is also reduced in size, and the components mounted on the substrate are also referred to as bumps on the bottom surface of the shape without electrode lead wires. There are an increasing number of micro components having hemispherical electrodes. These micro components are usually supplied by a tape-type component supply device for mounting a tape having a width of 8 mm, which is a minimum component tape.

  The narrower the tape-type component supply device, the greater the number of tape-type component supply devices that can be mounted on the component supply stage of the component mounting device, and the tape-type component supply device must be replaced in a tight work space. As a result, the number of setup operations described above, that is, the time, is increasingly required, and there is an increasing demand for solving the troublesome tasks in such setup operations.

And in order to cope with such a request, the modular general-purpose component mounting apparatus has become mainstream in this industry. This type of component mounting device prepares a plurality of mobile component supply stage trolleys (also referred to as transport trolleys or collective replacement trolleys) that separate the component supply stage from the device body into a trolley, and supply the components. The number and type of tape-type component supply devices necessary for the board unit to be produced next time are pre-arranged on the stage supply stage of the stage carriage, and new and old parts are used when switching the production model of the board unit. Replace the supply stage carriage, connect the new parts supply stage carriage to the parts mounting equipment, place the parts supply stage carriage parts supply stage at the position of the parts supply stage of the parts mounting equipment, and collect the tape parts A method of arranging the supply device on the component mounting device has come to be adopted. (For example, refer to Patent Document 1 or 2.)
By doing the above, only the time for attaching and detaching the component supply stage carriage without stopping the board production line for a long time to arrange the tape type component supply devices one by one on the component supply stage of the component mounting device. The substrate production line can be set up immediately by simply stopping the substrate production line.
