Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an electronic component insertion device for inserting various electronic components into a printed circuit board, and particularly for inserting various electronic components of irregular shapes such as LC filters and delay lines. The present invention relates to an electronic component insertion device suitable for the purpose of the present invention.

[Prior Art] As an example of an irregularly shaped electronic component, during the manufacturing process of the electronic component, the position of the lead may deviate from the external shape of the component when a thin coil wire is wound around the lead, soldered, and then covered with a protective cover. When grasping the main body of such a component and automatically inserting it into a hole in a printed circuit board, the lead position and the hole position in the circuit board do not match, resulting in an insertion error.

Therefore, in order to solve this problem, conventionally, for example,
As described in No. 9-156000, a gripping device for a component body is held in a floating manner within a cylinder,
It has been proposed that after positioning the lead, the component body is gripped, and the gripping device is fixed within the cylinder by the pressure of fluid into the cylinder, thereby gripping the component body based on the lead. .

[Problems to be Solved by the Invention] In the above-mentioned prior art, parts with thin lead wires that bend easily, parts with thin coil wires wound and soldered around the leads and which do not want to put a load on the leads, and parts with thin lead wires that protrude from the main body The root part of the lead is filled and fixed with resin, etc., and no consideration is given to handling parts with weak leads, which may cause the parts to be damaged or deformed, absorbing the misalignment between the part body and the lead position. There is a possibility that you may not be able to do so.

That is, in the prior art, the floatable gripping assembly is composed of an upper part and a flange part, and is also composed of a gripping actuator that drives a gripping member that grips a component, so that the weight of the gripping assembly itself is reduced. becomes larger.

and the flange portion of the floatable gripping assembly is pressed against the bearing plate by applying fluid pressure to the air chamber and radially disposed about the flange portion by removing fluid pressure from the air chamber. The center position is determined by a compressed spring.

Therefore, the flange portion of the floatable gripping assembly is brought into contact with the bearing plate due to the pressing force of the compression spring due to the weight of the gripping assembly and the actuator, so that the flange portion is in contact with the component body and the lead position. When the frictional force increases when sliding on the bearing plate by the amount of eccentricity between the lead and the lead, a load is applied to the base of the lead that is receiving this frictional force, causing damage to the part and bending of the lead. It may not be possible to absorb the amount of eccentricity with respect to the position.

SUMMARY OF THE INVENTION An object of the present invention is to solve the problems of the prior art described above, and to provide an electronic component insertion device that can absorb eccentricity between the component body and the lead position without causing damage to the component or bending of the lead. There is a particular thing.

[Means for Solving the Problems] The above object is to provide an insertion head having a component gripping body for electronic components, a holding mechanism for forcibly floating the component gripping body and fixing the component gripping body, This is achieved by providing a positioning mechanism for positioning the insertion head.

[Operation] After positioning the insertion head that grips the electronic component at a predetermined position, when the component body of the electronic component is gripped by the component gripping body of the insertion head, the component gripping body is forcibly floated. The part gripping body is moved horizontally in a horizontally movable state, and the part gripping body is moved horizontally in the locked state to grip the component body, and the gripping diameter component body is fixed, so the frictional force when the component gripping body moves horizontally is small. As a result, the load applied to the electronic components is reduced.

The air chamber 6 is opened by the air discharged from the air escape hole 641b.
According to Bernoulli's theorem, the pressure between the upper end surface of the flange 642 and the upper end surface of the flange 649 becomes equal to or higher than atmospheric pressure near the air escape 641a, but the pressure around it becomes negative pressure. In addition to this, the flange 649 floats upward due to the upward pressure of the air in the air outlet hole 645a of the lower plate 645 and is forcibly separated from the upper end surface of the lower plate 645, and the parts held by the lower plate 645 are The two chucks 601 and 602 of the gripper are now movable horizontally freely and with little force.

The function of floating the bearing 5 above the upper end surface is generally called an air slide bearing, and for details, please refer to, for example, Japanese Patent Laid-Open No. 143989/1983.

Therefore, the present invention provides a component main body 10a of the electronic component 10.
Since the center of the lead 10b is eccentric, unless the two chucks 601 and 602 are moved horizontally,
The two chucks 601 and 602 when the component main body 10a cannot be gripped or the lead 10b cannot be inserted into the hole 9a of the substrate 9.
Since the above condition is applied when moving in the horizontal direction,
The chucks 601 and 602 can be moved horizontally with little friction and small force.

After that, the two chucks 601 and 602 grip the component body 10a, or the lead 10. When the piston rod is completely inserted into the hole 9a of the substrate 9, air is supplied from the air intake port 638a into the piston rod hole 638, and the flange 649 is inserted through the clamp piston 639.
is lowered and pressed against the upper end surface of the lower plate 645, so that the component gripping body Yu is fixed to the holding mechanism U.

The vertical mechanism competition is configured as described below.

That is, 681 is a vertical mechanism main body, which is formed in a cross section and held on the side surface of the upper part of the frame 403, and is attached to the insertion head main body 6 of the holding mechanism U of the insertion head.
31 is slidably inserted in the vertical direction, and holes 682a*682b are formed in the upper and lower parts to penetrate in the vertical direction. 6
A guide bar 83 is fitted into the insertion head main body 631 so as to be movable in the vertical direction, and both ends of the guide bar in the vertical direction are fixedly supported by the vertical mechanism main body 681. 684 is a piston, and the upper large-diameter piston 684a is fitted into the cylinder 633 of the insertion head main body 631 so as to be vertically movable, and the lower small-diameter piston 684b is slid vertically into the piston hole 634. It is freely inserted and inserted into the lower hole 682b of the vertical mechanism main body 681. 685 is an air inlet, and the small diameter piston 6
It is perforated vertically from the lower end of the piston 84b and perpendicularly horizontally from near the boundary between the small-diameter piston 684b and the large-diameter piston 684a, and opens into the cylinder 633.

Therefore, when air is supplied into the cylinder 633 from the air intake port 635 of the insertion head main body 631, the insertion head main body 631 is pressed upward by the air pressure, and the air inflow port 685 causes the cylinder 633 to enter the cylinder 633.
When air is supplied inside, the insertion head main body 631 is pressed downward. Although the internal structure of the clinch main body unit is not shown, it is installed at a position below the substrate 9, that is, at a position opposite to the insertion head with respect to the substrate 9, and the insertion head opens the hole 9a of the substrate 9. The tip of the lead 10b of the electronic component 10 inserted therein is bent and the mounting state of the electronic component 10 can be inspected.

The delivery section is as shown in FIGS. 4 to 6.

It is installed at the tip of the main rail 301 of the electronic component supply section, and is configured as described below. That is, 80
Reference numeral 1 denotes a clamp plate, and the tip of one rail 301a of the rail 301 is made shorter than the tip of the other rail 301b, and is arranged so as to face the other rail 301b in the direction of the tip. Reference numeral 802 designates a compression spring for clamping, which is inserted between the opposite ends of the opposing surfaces of the other rail 301b and the clamp plate 801 so as to always keep the clamp plate 801 away from the other rail 301b with one elastic force. There is.

Reference numeral 803 designates a fixed plate, which is fixed in parallel with the clamp plate 801 at an interval, one end of which is inserted into the fixed plate 803 so as to be fixed against movement in the axial direction, and the other end is inserted into the fixed plate 803 so that movement in the axial direction is fixed. It penetrates the other rail 301b and the clamp plate 801 and is inserted into the other rail 301b so that movement in the axial direction is fixed, so that the clamp plate 801 can be freely moved in the direction toward and away from the other rail 301b. Two guide bars 804 are installed to support the guide bars 804, and their tips are constantly pressed against the outer surface of the clamp plate 801 (the opposite surface of the other rail 301b) by the elastic force of the clamp compression spring 802. ), two stopper screws 805 are installed to adjust the amount of gap between the clamp plate 801 and the other rail 301b, and a clamp cylinder 806 and an air supply inside the clamp cylinder 806 are installed in the center. A clamping piston rod 807 that moves axially toward the clamp plate 801 due to displacement.
and has been set up. A stopper 808 is fixedly supported on the tip of the other rail 301b in a direction perpendicular to the longitudinal direction of the other rail 301b.
01, and the electronic components 10 supplied thereto are stopped.

Therefore, the delivery section first adjusts the gap between the other rail 301b and the clamp plate 801 using two stopper screws 805, and then inserts the electronic component 10 from the electronic component supply main body 303 so that its lead 10b is in the guide hole. 302 and when the electronic component 10 reaches between the other rail 301b and the clamp plate 801, the clamp cylinder 80
The tip of the clamping piston rod 807 presses the clamp plate 801 due to the pressure of the air supplied to the electronic component 10, and the lead 10h of the electronic component 10 can be brought into contact with the stopper 808 and stopped while reducing the supply speed of the lead 10h. Then, when air is discharged from the clamping cylinder 806 and the tip of the clamping piston rod 807 moves inward in the axial direction, the clamping plate 801 is moved against the clamping compression spring 8.
With the elastic force of 02, the lead 10b of the electronic component 10 can be released from the fixation by moving away from the other rail 301b.

Since the electronic component device according to the present invention is configured as described above, the servo motor 401 of the X-direction positioning unit-4- and the servo motor 501 of the Y-direction positioning unit are driven in advance to move the frame 403 in the X direction. At the same time, the insertion head 6 is moved in the Y direction to position the two chucks 601 and 602 above the stopper 809 of the delivery section.

Next, the electronic component supply section y supplies the electronic component 10 to the rail 301 with its lead 10b inserted into the guide hole 302, and then supplies the electronic component 10 to the delivery section 301 to the other rail 301.

When one chuck 601 comes into contact with the component body 10a with a difference of δ between the gap amount and the gap between the chuck 602 and the component body 10a, the other chuck 602 is still in contact with the component body 10a.
Since there is a gap of δ between the flange 6 and the flange 6
49 is floating in the air chamber 647 in the horizontal direction δ/
After horizontal movement by 2, the two chucks 601 and 602 grip the component body 108 as shown in FIG.

After that, when air is supplied into the clamp cylinder 637 from the air intake port 638a of the holding mechanism, the clamp piston 639 is compressed by the clamp piston compression spring 640.
The lower end surface of the lower end surface presses the flange 649 against the upper end surface of the lower plate 645, so that the component gripping body is fixed to the holding mechanism brocade.
