  According to the third aspect of the present invention, since the operation handle can also be used, the number of parts can be reduced.

  A first embodiment of the present invention will be described with reference to FIGS.

  FIG. 1 shows a line configuration for forming a general circuit board. From the left side of the drawing, a board carry-in machine 1, a solder printer 2, a first surface mounting machine (surface mounting machine) 3, and a second surface mounting machine. (Surface mounter) 4, reflow oven 5, and substrate collector 6 are disposed. The first surface mounter 3 and the second surface mounter 4 have the same structure, and are connected to one line in order to be applied to mounting various types of components.

  As shown in the first surface mounter 3, each of the devices 1 to 6 constituting one line includes legs 7, 7, 8, and 8 at four corners. In the line-configured apparatus, the upper part in the figure is the operation surface side X and the lower part is the non-operation surface side Xa. Leg portions 7 and 7 are arranged on the operation surface side X, and leg portions 8 and 8 are arranged on the non-operation surface side. A direction orthogonal to the operation surface side X is defined as Y. FIG. 2 shows the first surface mounter 3 having the line configuration of FIG. 1 cut in the Y direction. FIG. 3 is an enlarged view of the operation surface side X leg portion 7 in FIG. 2, and FIG. 4 is an enlarged view of the counter operation surface side Xa leg portion 8.

  The first surface mounter 3 includes a component supply unit (not illustrated), a mounting head unit (not illustrated), a level (not illustrated), a machine frame 10, an adjustment bolt 11, a loosening prevention nut 12, and a counter-operation surface side gear 13. And a drive member 14, a handle member 17 and the like.

  Electronic components are accommodated in a component supply unit (not shown) provided in the first surface mounter (surface mounter) 3. On the upper part of the component supply unit, there is disposed a mounting head unit for taking out electronic components from the component supply unit and mounting them on a substrate (not shown). This mounting head portion is supported by the machine casing 10 so as to be movable.

  Legs 7 and 8 are provided at the bottom of the machine casing 10. These are composed of an operation surface side leg portion 7 and a counter operation surface side leg portion 8.

First, the operation surface side leg portion 7 will be described with reference to FIG.
The operation surface side leg portion 7 includes a machine frame 10, an adjustment bolt 11, and a slack prevention nut 12. The adjustment bolt 11 includes a main body portion 11a, an upper screw portion 11d, a ball-like lower portion 11b, and a leg plate 11c that fits with the ball-like lower portion 11b at the lower portion of the main body portion with play. .

  In addition, screw holes 10 a are formed at the bottom four corners of the machine casing 10. An adjustment bolt 11 is screwed into each of the screw holes 10a and is fixed so that the height can be adjusted. A loosening prevention nut 12 is attached to the top of the adjustment bolt 11 to hold the adjustment bolt 11 in a fixed state.

Next, the non-operation surface side leg portion 8 will be described with reference to FIG.
The non-operation surface side leg portion 8 includes a machine frame 10, an adjustment bolt 11, a slack prevention nut 12, a counter operation surface side gear 13, a drive member 14, and a handle member 17.

  The adjustment bolt 11 includes a main body portion 11a, an upper screw portion 11d, a ball-like lower portion 11b, and a leg plate 11c that fits with a ball-like lower portion at the lower portion of the main body portion with play. .

  In addition, screw holes 10 a are formed at the bottom four corners of the machine casing 10. An adjustment bolt 11 is screwed into each of the screw holes 10a and is fixed so that the height can be adjusted. A loosening prevention nut 12 is attached to the top of the adjustment bolt 11 to hold the adjustment bolt 11 in a fixed state.

  An adjustment bolt-equipped gear (counter operation surface side gear) 13 is fixed to the main body portion 11a of the adjustment bolt 11 on a concentric shaft. A worm wheel 14a is disposed on the outer periphery of the gear 13 with the adjusting bolt. The worm wheel 14a is vertically long and meshes with the gear 13 with the adjusting bolt.

  A worm 14b is disposed on the worm wheel 14a. The worm 14b has its axis oriented in the horizontal direction and its outer peripheral portion meshes with the worm wheel 14a. The worm wheel 14a and the worm 14b constitute a drive member (worm gear) 14.

  The worm 14 b is fixed to the outer periphery of the shaft 15. One end of the shaft 15 is rotatably supported by the machine casing 10 and extends from the non-operation surface side Xa toward the operation surface side X. The shaft 15 has a connecting portion 15a at the center thereof, and 2 are detachable. A handle 16 is attached to the other end of the shaft 15 on the operation surface side. A handle member 17 is constituted by the shaft 15 and the handle 16.

  When the handle 16 is turned, the shaft 15 rotates. When the shaft 15 rotates, the worm 14b and the worm wheel 14a rotate. This rotation is transmitted to the gear with the adjustment bolt, and the adjustment bolt 11 is rotated. By this rotation, the adjustment bolt 11 moves up and down to adjust the height of the surface mounter 3.

  The operation of the first embodiment will be described. First, the worker moves to the operation surface side X of the surface mounter 3. Next, the two adjustment bolts 11 on the operation surface side X are directly rotated and moved up and down. Next, the handle member 17 located on the operation surface side X is rotated, and the two adjustment bolts 11 on the non-operation surface side Xa are moved up and down. Then, while looking at the level, the surface mounter 3 is set within a predetermined level of horizontality while adjusting the height of the four adjustment bolts 11 on the operation surface side X.

  According to the first embodiment, the height adjustment of all the adjustment bolts 11 can be performed on the operation surface side, so that the leveling operation becomes easy.

  In particular, in the devices 1 to 6 configured in a line, for the leveling operation, as shown by the symbol W in FIG. Leveling work can be performed only by moving the operation surface side X.

  Moreover, since the drive member 14 is comprised from the worm 14b and the worm wheel 14a, the adjustment bolt 11 can be rotated with a smaller force. Further, the handle member 17 may be provided with the handle 16 individually, but the number of parts can be reduced by providing a single handle in the apparatus.

The present invention is not limited to the above embodiment and can be variously modified.
For example, in the above-described embodiment, the gear 13 is fixed to the two adjustment bolts 11 on the counter-operation surface side Xa and is connected to the handle member 17. It can be easily considered that the gear 13 is fixed to the individual adjusting bolts 11 and is connected to the handle member 17. At this time, at least one handle 16 may be provided.

  Moreover, in the said embodiment, although the shaft 15 was used as a member which transmits motive power, it replaces with this and using a belt or a chain can also be considered easily.

  In the above embodiment, the operation is performed on the operation surface side X. However, it is easily conceivable to operate the operation surface side Xa by changing the arrangement.

It is explanatory drawing of the line structure for forming a circuit board. The first surface mounter 3 having the line configuration of FIG. 1 is cut in the Y direction. FIG. 3 is an enlarged view of an operation surface side X leg portion of FIG. 2. FIG. 2 is an enlarged view of the Xa leg portion on the side opposite to the operation surface in FIG. 2.
