Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a device for supporting a circuit board when various electronic components are mounted on the circuit board.

[Conventional technology]

When mounting various electronic parts, etc. on both the front and back sides of a circuit board such as a printed circuit board, a plurality of such circuit boards are first placed on a horizontal surface such as a table with the front surface facing upward. Attach the electronic parts of
The circuit board is turned upside down so that the back surface is the upper surface, and a plurality of electronic parts are attached to the circuit board. When the circuit board is turned upside down as described above, the lower surface is The circuit board cannot be placed on and supported by a horizontal surface such as a table because the circuit board is uneven due to the mounting of electronic parts and the like.

Therefore, conventionally, a dedicated jig having an upper surface formed on an uneven surface corresponding to the uneven shape of a plurality of electronic parts or the like to be attached to the back surface of the circuit board is prepared, and the circuit board flipped over by this jig is used. I try to support it.

[Problems to be solved by the device]

However, the method of using a dedicated jig whose top surface is shaped to match the irregularities on the circuit board is as described above. Each time the number, type, and arrangement position of the jigs, etc. changes, a jig corresponding to this must be manufactured separately. Therefore, various jigs can be manufactured, jigs can be replaced, and many kinds of jigs can be replaced. Storage and management of jigs requires a great deal of labor and is inefficient, and also requires a great deal of expense.

The present invention provides a support device which has a very simple structure and can be stably and reliably supported by an extremely simple operation even if the shape of the unevenness on the front surface or the back surface of the circuit board is changed. It is intended to be provided.

[Means for Solving the Problems]

In order to achieve this object, the present invention provides a base with a plurality of support pins configured to be slidable in the vertical direction and appropriately pitched so that each of the support pins protrudes upward from the top surface of the base. Springs for separately urging the support pins in the upward direction are provided on the respective support pins, while the support pins are provided on the upper surface of the platform. The locking operation plate having a hole into which the split claw body in each of the support pins fits is arranged so as to be vertically movable, and the locking operation plate is mounted on the base. Each of the split claws is opened when it is moved downward toward the board, and each of the split claws is closed when the locking operation plate is moved upward,
A spring for urging the locking operation plate in an upward direction is provided on the locking operation plate, and further, a detachable locking for locking the locking operation plate in a lowered state on the base. It is configured to have means.

[Action]

In such a structure, when the locking operation plate is pushed down against its spring, the split claws in each of the support pins open simultaneously, so that the locking operation plate is locked by the locking means. Then, the circuit board is placed on the tip of each support pin, and the circuit board is pressed downward while the circuit board is held in a substantially horizontal state. Then, each support pin is pushed down all at once against the spring means in a state where the upper end of the support pin is in contact with the circuit board or an electronic component attached to the circuit board.

Therefore, in this state, when the locking of the locking operation plate by the locking means is released, the locking operation plate automatically moves up by its spring, and the split claw bodies in each of the support pins are released. Since the support pins can be closed all at once, the support pins can be fixed to the positions where the tips of the support pins are in contact with the circuit board or the electronic components attached to the circuit board. It is possible to support the state.

[Effect of device]

Thus, according to the present invention, the locking operation plate is locked in a depressed state, then the circuit board is placed on the tip of each support pin, the circuit board is pressed downward, and then the locking operation plate is pressed against the locking operation plate. By releasing the locking by the locking means,
Since the circuit board can be surely and stably supported in a state of being matched with the concave-convex shape of the lower surface thereof, the work efficiency in supporting the circuit board when mounting the electronic component or the like on the circuit board is remarkably high. Can be improved,
This has the effect of reducing the cost required for this.

In addition, according to the present invention, the split claw bodies fitted in the respective support pins can be simultaneously opened and closed by moving the locking operation plate up and down.
As described in Japanese Patent Laid-Open No. 34-34, the structure is remarkably simpler than that in which the clamp mechanisms provided for each of the support pins are actuated at the same time, and it can be provided at a low cost.

In addition, the locking operation plate is locked in the depressed state, the circuit board is pressed downward, and then the locking with respect to the locking operation plate is only released, and the operation is simple and quick. Therefore, it also has an effect of high workability.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. In this figure, reference numeral 1 indicates a base mounted on the upper surface of a floor 2 or the like, and the base 1 is configured to be slidable in the vertical direction. The plurality of support pins 3 are arranged in a grid pattern.

Inside the base 1, springs 4 for individually biasing the support pins 3 upward are provided at the lower end portions of the support pins 3, respectively.

On the other hand, a plate body 5 through which the support pins 3 penetrate is provided on the upper surface of the base 1, and a cylindrical split claw body 6 is fitted on the support pins 3 on the plate body 5. Stick as you do.

Further, on the upper surface of the plate body 5, a locking operation plate 7 having a hole 8 into which each of the split claw bodies 6 is fitted is arranged so as to be vertically movable.
When the locking operation plate 7 is lowered by loosening the setscrew 9 for the base plate 1, the split claw bodies 6 are opened at the same time to allow the support pins 3 to slide, and the locking operation plate 7 is moved. When rising,
The respective split claw bodies 6 are closed at the same time so that the respective support pins 3 are locked so as not to slide.

Furthermore, a spring 10 for biasing the locking operation plate 6 upward is interposed between the plate body 5 and the locking operation plate 6.

In this structure, the locking operation plate 6 is pushed down against the spring 10 thereof, and the set screw 9 is pushed down in this depressed state.
Then, the circuit board A on which a plurality of electronic components B are previously mounted is placed on the upper ends of the support pins 3 with the mounting surface of the electronic components B facing downward. Then, when the circuit board A is pressed downward while being held in a substantially horizontal state, each support pin 3 has its upper end attached to the circuit board A or the circuit board A as shown in FIG. While being in contact with the electronic components B, the springs 4 are pushed down all at once against the spring 4.

Then, by loosening the setscrew 9 for the locking operation plate 7, the locking operation plate 7 is automatically raised by its spring 10, whereby the split claw bodies 6 are closed at the same time, and each current claw is closed. Since the pin 3 is locked so that it cannot slide, the circuit board A
Can be supported in a substantially horizontal state by the respective support pins 3.
