FIG. Reference numeral 2 denotes a mounting table, and a cushion 4 is provided at the bottom of the table to increase the frictional force against a flat surface such as a worktable. Reference numeral 10 denotes a rotary support base consisting of a flat plate portion 12 and support columns 14 and 16, and this rotary support base 10 is rotatably provided on the mounting base 2 via a bearing 6 and a spacer 8. This rotational movement can be fixed by inserting the lock pin 11 attached to the flat plate part 12 into any one of the plurality of lock holes 2a provided in the mounting table 2. .

Reference numeral 17 denotes a frame that is rotatably provided with respect to the rotation support base 10, and this frame 17 includes a shaft block 20 that is rotatably provided on the support column 14 of the rotation support base via a shaft 18, and a support column. A shaft block 2 rotatably provided at 16 via a shaft 22
4, shaft rails 26, 28 fixed to the shaft blocks 20, 24, respectively, and bar frames 30, 32 slidably provided on the shaft rails 26, 28. The reason why the bar frames 30 and 32 are movable is to enable this holder to be applied to printed wiring boards of various sizes. Bar frame 30 has screw 3
4 and 36, the bar frame 32 is secured to the screw 3
8 and 40, it is possible to manually tighten and position and fix the shaft rails 26 and 28, respectively. 42 is a clamp block fixed to the support column 16 of the rotating support base;
By tightening the shaft 22 with the clamp block 42, the rotational movement of the frame 17 can be fixed. 46 is a clamp block 42
It is a fixing screw for tightening, and has a handle 44 to facilitate manual operation.

The printed wiring board holding means is constructed as follows. A fixed holding part 48 is fixed to the bar frame 32 and holds one edge of the printed wiring board 58. 50 is bar frame 30
This is a movable holding part that is provided to be slidable and rotatable relative to the printed wiring board 58, and holds the other edge of the printed wiring board 58. The movable holding part 50 is urged by a biasing member 54 in the direction of the rotation stopper 32 fixed to the bar frame 30, and the convex part 50a of the movable holding part 50 fits into the recess 52a of the rotation stopper 52. In the fitted state, the rotational movement of the movable holding part 50 is fixed, and in the unfitted state, the movable holding part 50 rotates within the range of the urging force of the urging member 54. It is becoming possible to do so.

FIG. 4 is a diagram for explaining the holding operation of the printed wiring board. First, in the state shown in FIG. a (the convex portion 50a is not fitted into the concave portion 52a), one edge of the printed wiring board 58 having the electronic component 56 is fixed to the groove 48 formed in the holding portion 48.
Loosely fit into a. Then, the movable holding part 50 is rotated to the state shown in FIG.
a), the other edge of the printed wiring board 58 is held by the groove 50b formed in the movable holding part 50.

In FIGS. 1 to 3, 74 is a pressing plate to which an elastic body 76 made of a heat-resistant material such as heat-resistant sponge is attached.
It is provided so as to be openable and closable via a hinge 72 with respect to a substantially U-shaped support member 68 fixed to the shaft block 20. A latch 78 is provided on the opposite side of the pressing plate 74 from the hinge 72, and by engaging the latch 78 with a latch receiver 80, the electronic component 56 on the held printed wiring board 58 is released. It can be pressed with an elastic body 76. The latch receiver 80 is secured to the shaft block 24 by a generally U-shaped support member 70. When it is necessary to prevent the electronic component to be mounted from being charged, a conductive sponge can be used as the material for the elastic body 76. Note that when the mechanical strength of the printed wiring board 58 is low, as shown in FIG. Therefore, it is preferable to prevent deformation of the printed wiring board 58.

When removing the printed wiring board 58 from this holder, first release the latch of the pressing plate 74, then slide the movable holder 50 to the right in FIG. 1, and then rotate it. Printed wiring board 5
It can be taken out from one edge of 8.

In this embodiment, the rotation center of the rotation support 10 is located at a position that approximately divides the held printed wiring board 58 into two, so that the rotation center of the rotation support 10 is at the rotation center of the printed wiring board 58. Since they almost match, the frame 17 holds the printed wiring board 58 and the printed wiring board 58
The electronic component 56 is mounted on the surface side of the pressing plate 74.
When the rotary support base 10 is rotated approximately 180 degrees about the vertical axis of rotation in order to perform work on the back side of the printed wiring board 58 after closing the printed wiring board 58, the rotation of the rotary support base 10 causes the printed wiring board 58 to This position is approximately the same as the previous position, making it easier to perform soldering work on the back side of the printed wiring board 58 (on which wiring patterns and the like are formed, for example). In particular, when the printed wiring board 58 is on a substantially horizontal plane and the front side of the printed wiring board 58 (the side on which the electronic component 56 is mounted) faces upward when mounting the electronic component 56, the frame 17
Even after performing an operation of rotating approximately 180 degrees about the horizontal rotation axis and an operation of rotating the rotation support 10 approximately 180 degrees about the vertical rotation axis, the upper and lower parts of the printed wiring board 56 within the operator's field of vision remain unchanged. Since the front and back sides of the printed wiring board 58 can be switched while maintaining the relationship, work efficiency is significantly improved.

Effects of the Invention According to the configuration of the printed wiring board holder of the present invention described in detail above, it becomes possible to arbitrarily change the posture of the printed wiring board with electronic components attached before being soldered and fixed. This has the effect of improving workability.

Further, by configuring the printed wiring board holding means as in the embodiment, there is an effect that the holding operation of the printed wiring board can be simplified.
