BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component mounting apparatus for mounting components on a substrate, and more particularly to a component mounting device for easily and properly supporting a substrate in a horizontal state.

[0002]

[Prior art]

FIGS. 4 to 6 show a component mounting apparatus. The component mounting apparatus includes a board 1 supported in a horizontal state.
This is a device for installing electronic components such as a diode and an LSI at a predetermined position with respect to a (substrate of an electric device).

In FIG. 1, reference numeral 5 denotes support means, which supports the substrate 1 in a horizontal state, and comprises two belt conveyors on which both end portions of the substrate 1 are placed as shown in FIG. The board 1 can be moved in the direction shown by the arrow Y so as to facilitate insertion and removal of the board 1 from the component mounting apparatus. Reference numeral 4 denotes a component transfer unit. The component transfer unit 4 includes a moving arm 3 provided above the substrate 1 supported in a horizontal state as shown in FIG. It is configured.

The moving arm 3 comprises an X moving arm 3a movable in the X direction in the figure and a Y moving arm 3b provided on the X moving arm 3a and movable in the Y direction. Is provided at the lower end of the Y moving arm 3b so as to face the substrate 1. Reference numeral 9 denotes component supply means. The component supply means 9 supports a plurality of types of support members 7 which support component reels 6 on which electronic components are wound at predetermined intervals, as shown in FIG. A plurality (60 to 100) of supply cylinders 8 (see FIG. 5) are provided to drive the component reels 6 so as to take out the components from the plurality of component reels 6, respectively.

In the component mounting apparatus provided with the above-described respective means, after the substrate 1 is moved to a predetermined position by the support means 5, the moving arm 3 of the component transfer means 4 is moved between the component reel body 6 and the substrate 1. The movement of holding the components of the component reel 6 by the suction unit 2 and mounting the components to a predetermined position on the substrate 1 is performed a plurality of times. The component supply means 9 is driven so that the next component to be supplied can be taken out while the component transfer means 4 is transferring the component, and the supply cylinder 8 is connected to an air supply source (not shown) and the air control means 10 respectively. The air is supplied only when necessary by the air control means 10.

By the way, in this component mounting apparatus, the substrate 1 which is supported horizontally by the support means 5 so that both end portions are mounted, the central portion is bent by the weight, and the component cannot be installed at an appropriate position. Inconvenience occurs. Since the components are also provided on the back surface of the substrate 1, the upper surface of the support means 5 cannot be formed wide so as to reach the back surface of the substrate 1.

For this reason, a substrate stabilizing means shown in FIG. 6 has been proposed today. In FIG. 6, reference numeral 12 denotes an iron plate. The iron plate 12 can be moved up and down while maintaining a horizontal state by a vertical foot 12a and a support plate 12b that supports the vertical foot 12a so as to pass therethrough. Reference numeral 13 denotes a cylinder that fixes the advance / retreat portion to the iron plate 12 and moves the iron plate 12 up and down.

Reference numeral 14 denotes a support member. The support member 14 has a magnet at its lower end and a vertical bar extending vertically as shown in FIG. The upper end is in contact with the bottom surface of the substrate 1. By mounting a plurality (three in the figure) of the support members 14 on the iron plate 12, the substrate 1
Can be solved.

[0010]

However, the above-mentioned conventional component transfer apparatus has the following problems. The board stabilizing means of the conventional component mounting apparatus uses an iron plate 1 to prevent the components from being damaged by contact with the components installed on the back surface of the board 1.
The support member 14 must be installed at an appropriate position on the upper surface of the substrate 2, and this installation operation has to be performed with a complicated and time-consuming operation while checking the back surface of the substrate 1.

In particular, in recent years, high-mix low-volume production has been required, and the position of the support member 14 has to be changed complicatedly every time various substrates are replaced, which causes a decrease in work efficiency and production efficiency. Had become.

According to the present invention, there is provided a support means for supporting a substrate in a horizontal state, a component supply means for storing and holding components, and a moving means provided to move in the X and Y directions on the substrate. A component transfer means comprising a suction unit provided at a lower end of the arm and the moving arm, wherein the component of the component supply means is sucked and held by the suction unit, moved to the substrate, and the component can be placed on the substrate; X below the substrate supported by the support means
A plurality of support rods arranged in rows and columns in the Y-direction and having an upper end capable of contacting the bottom surface of the substrate, and a plurality of air separately connected to the support rods and raising the support rod to a position where the tip comes into contact with the bottom surface of the substrate by action. A cylinder and an air-control means for selectively operating the air cylinder, wherein the component transfer device includes: a protruding portion provided on the outer periphery of an intermediate portion of each of the support rods; The upper surface is arranged so as to be movable in the lateral direction between the protrusions, and the protrusion of each support rod forms a plurality of through holes that can be individually penetrated, and the upper surface that can be engaged with the lower surface of the protrusion when moving in one direction. A contact plate having
This is achieved by preventing the lowering of the support rod by the engagement between the lower surface of the protrusion and the upper surface of the contact plate.

[0013]

In the component mounting apparatus according to the present invention, a plurality of lifting cylinders each having a support rod suitable for supporting the back surface of the substrate are raised by switching a plurality of air control means.

Then, the contact plate is moved in the lateral direction, and the contact plate is brought into contact with the protruding portion of the support rod to prevent the raised support rod from descending and release the lifting of the lifting cylinder by the air control means. To properly support the substrate. When the component mounting apparatus is driven, the air control means controls only the driving of the supply cylinder.
