Description

[Detailed description of the invention] (Industrial application field) The automatic machine tool for rotating electronic components of the present invention is a tool that replaces the conventional screwdriver, and automatically measures the electrical characteristics etc. of electronic components by rotating them. It is used by being attached to automatic machines (industrial robots) such as automatic adjustment machines and automatic inspection machines that adjust and inspect.

Furthermore, when the tool for automatic machines of the present invention is set on an electronic component to be adjusted or inspected, the tool is reliably set on the electronic component even if the tool is slightly misaligned with the electronic component. be.

(Prior Art) Conventionally, in order to adjust or inspect the electrical characteristics of an electronic component, a worker would fit a screwdriver or other tool into a groove in the electronic component or place it over the rotating shaft of the electronic component. This was done by rotating the electronic components by rotating the screwdriver or other tools.

However, this method has the problem of poor workability and high labor costs because the tool must be inserted into the groove or placed over the rotating shaft.

Therefore, the inventor of the present invention has developed an automatic adjustment machine that can rotate electronic components and automatically adjust and inspect electronic components without using any human hands.
Developed automatic machines such as automatic inspection machines. In these automatic machines, when a board on which electronic components such as a volume control coil and a brake coil are mounted is conveyed to a predetermined position by a belt conveyor, etc., it automatically lowers and places a tool such as a screwdriver on the rotating shaft of the electronic component. The tool is automatically set, and once set, the tool is used to rotate the rotating shaft of the electronic component using a motor, etc. to adjust or inspect the electrical characteristics of the electronic component, and when that is completed, it is automatically raised. In this state, the belt conveyor moves to convey the next board to the bottom of the tool, and the above operation is repeated to sequentially adjust and inspect the electronic parts. be.

However, when an operator adjusts an electronic component, a tool such as a screwdriver is reliably set in the groove or rotation of the electronic component to be adjusted, but when the adjustment is done automatically, it not only rotates the electronic component, but also adjusts the electronic component. Since the tool is also set mechanically, if the tool and the electronic component are misaligned during setting, the tool may not be reliably set on the electronic component, and adjustments, inspections, etc. may not be possible.

In addition, in the case of automatic machines, when a board such as a printed circuit board on which electronic parts are mounted is conveyed to a predetermined position by a conveyor, etc., and stops, the installed tools automatically Since the tool is pressed against the component, if the tool is misaligned from the electronic component, the tool will not be set in the specified position on the electronic component and will be pressed against other parts of the component, causing damage to the electronic component or tool. Damage may occur. In such cases, work such as adjustment and inspection may be stopped.

Therefore, with the development of this type of automatic machine, there is a demand for the development of tools that can be reliably and smoothly set on electronic components.

Therefore, the inventor of the present application created a tool A as shown in FIG.
was developed. This tool A is formed into a plate shape like the tip of a conventional screwdriver, and is used by being attached to a jig B as shown in FIG. 5, which is detachable from an automatic machine. Jig B in Figure 5 is the movable part C
is connected to the base F by an axis D so that it can be swung 360 degrees in any direction from the part of the O-ring E, and by this oscillation, the tool A set on the electronic component G can be moved into the groove of the electronic component G. Even if it deviates somewhat from the shaped receiving part H, it will slide sideways and automatically fit into the receiving part H.

(Problem to be solved by the invention) However, since the tip end surface I of the conventional tool A is a flat plane, when the tool A is set in the groove-shaped receiving part H of the electronic component G, the solid line in FIG. As shown in , the widthwise central portion O of the tool A pressed against the electronic component G
When coincides with the center point P of the receiving part H, when the tool A pressed against the electronic component G is rotated in this state, the tool A rotates around the center point O in the longitudinal direction. As shown by the chain line in Figure 6, the tool A slides down into the insertion part H and is automatically inserted.
However, as shown by the solid line in FIG. 8, if the longitudinal center O of the tool A deviates from the center point P of the insertion part H
Even if the tool A pressed against the electronic component G is rotated in this state, the tool A only rotates around its center O and will not slip into the receiving part H. In this case, tool A cannot rotate electronic component G, so when electronic components are continuously conveyed using a belt conveyor or the like and adjusted in an assembly line style, there is a problem that the flow is interrupted and work efficiency decreases. It was hot.

(Purpose of the invention) The purpose of the invention is to set a tool for rotating an electronic component onto the electronic component, even if the tool pressed against the electronic component is slightly displaced from the insertion part of the electronic component. To provide a tool for an automatic machine in which when the tool is rotated while being pressed against an electronic component, the tool slides sideways into a receiving part of the electronic component and is automatically fitted into the receiving part of the electronic component.

(Means for Solving the Problems) As shown in FIG.
1, the movable part 12 is attached so that it can swing but not idle, and the base 11 and the movable part 1
2, an elastic O-ring E that is pressed when the movable part 12 swings is interposed between the automatic machine tool 4 and the movable part 12, and the automatic machine tool 4 is attached to the movable part 12 and rotated by the rotation of the movable part 12. , a fitting part 3 that fits into the receiving part H of the electronic component G is formed at the tip 2 of the tool 4, and the fitting part 3 is formed at an eccentric position from the widthwise center of the tip 2, and It is characterized in that the tip portion gradually protrudes from both sides in the width direction of the tip portion 2.

(Function) To use the automatic machine tool of the present invention, for example, do as follows.

As shown in FIG. 11, the tool 4 is attached to the movable part 12 attached to the lower part of the lower fitting plate 18 via the base 11, and in this state, the upper fitting plate 17 and the lower fitting plate 18 are lowered and the tool is removed. Press the tip of 4 against the electronic component G. In this case, if the position and orientation of the tip of the tool 4 match the position and orientation of the groove-shaped receiving part H of the electronic component, the tool 4 is automatically inserted into the receiving part H. In this state, when the base 11 and the movable part 12 are rotated by an automatic machine (not shown) to rotate the tool 4, the rotating part of the electronic component G is rotated, and the electrical characteristics of the electronic component G are adjusted, inspected, Measurements are taken. In the present invention, the insertion part 3 of the tool 4 is formed at a position eccentric to the side from the center in the width direction of the tip part 2, and protrudes gradually in a curved manner from both sides of the tip part 2 in the width direction toward the tip side. When fitting the fitting part 3 of the tool 4 into the receiving part H of the electronic component G, the fitting part 3 is slightly shifted from the receiving part H and pushed close to the receiving part H, as shown in FIGS. 2 and 3. When it hits, a diagonal force is applied to the movable part 12 of the jig 5 shown in FIG. 2, causing the movable part 12 to tilt diagonally as shown in FIG. 3. When the tool 4 is rotated in this state, the fitting part 3 of the tool 4 rotates around the receiving part H (on the annular line a in the figure) around the center line XX in FIG. When the distal end portion is rotated from the position shown by the solid line to the position shown by the imaginary line in FIG. 4, it slides into the receiving part H and is automatically fitted into the receiving part H. If the tool 4 is still rotated in this state, the rotating part of the electronic component G is rotated, and the electrical characteristics of the component are adjusted, inspected, measured, etc.

(Embodiment) FIGS. 1 to 3 show an embodiment of the automatic machine tool of the present invention. In these figures, reference numeral 4 denotes a tool for an automatic machine, which is formed into a plate shape so that it can be attached to a jig 5, and has a fitting part 3 formed at its tip 2. This fitting part 3 is formed at an eccentric position from the center in the width direction of the tip part 2 (lateral to the central axis X-X), and protrudes gradually in a curved manner from both sides of the tip part 2 in the width direction toward the tip side. ing.

As shown in FIGS. 9 and 10, the jig 5 consists of a base 11 that is attached to an automatic machine that rotates electronic components, such as an automatic adjustment machine or an automatic inspection machine, and a movable part 12 that is attached to the base 11. Further, the hexagonal ball part 15 of the connecting shaft 14 is fitted into the hexagonal hole 13 of the base 11, and the mouth part 16 of the hexagonal hole 13 is caulked to prevent the hexagonal ball part 15 from coming out from the hole 13, and the connection The shaft 14 and the movable part 12 fixed to it with a screw can be rotated at an angle θ in any direction of 360 degrees.
However, the corners of the inner circumferential surface of the hexagonal hole 13 and the corners of the outer circumferential surface of the hexagonal sphere 15 are engaged to prevent it from idling within the hexagonal hole 13.

Note that E in FIGS. 2, 3, 9, and 10 is a rubber O-ring, and when the movable part 12 swings as shown in FIG. This is to enable the movable part 12 to swing smoothly when pushed.

(Effects) The automatic machine tool of the present invention has the following effects.

When setting the fitting part 3 into the receiving part H of the electronic component G, even if the fitting part 3 is slightly shifted from the receiving part H,
If the tool 4 is rotated by the jig 5,
Since the fitting part 3 automatically fits into the receiving part H,
The setting becomes easy and reliable. Therefore, the fitting part 3 is not set into the receiving part H of the electronic component G,
Being able to adjust and inspect the electronic components G is never a problem, and adjustments and inspections can be carried out smoothly in an assembly-line manner, improving work efficiency.

If the fitting part 3 is made to protrude gradually in a curved manner from both sides in the width direction of the base material 1 toward the tip side, when the fitting part 3 is set in the receiving part H of the electronic component G, the fitting part 3 will be connected to the receiving part H. It becomes easier to fit into the receiving part H with a slight deviation.

If the tool 4 is attached to a jig 5 that can freely swing in any direction through 360 degrees, the insertion part 3 can be attached to the electronic component G.
Even if the fitting part 3 deviates slightly from the receiving part H of the electronic component G when it is set in the electronic component G, it becomes easier to fit the fitting part 3 into the receiving part H of the electronic component G.
