If the electronic components are not being pushed out of the shutter properly and the escaper chuck is insufficiently holding the electronic components, the electronic components will be reliably transferred to the loading chuck and then from the loading chuck to the insertion chuck. There is a risk that the electronic components cannot be transferred, and the timing of receiving and transferring electronic components between each chuck needs to be synchronized, which makes the structure complex and increases the number of parts, leading to higher costs. Ta.

Therefore, this invention has an inclined shutter that has a component ejection port at the lower end and supplies electronic components, and a tilted shutter that can receive the electronic components that have been supplied to the lower end of the shutter from the component ejection port and is movable in the vertical direction. There is a component supply chuck that transfers electronic components to the insertion chuck during upward movement, and a component supply chuck that is attached to the lower end of the shooter so that it can move horizontally toward the component supply chuck side, and is linked to the vertical movement of the component supply chuck. The component positioning slider moves to a position directly above the component supply chuck when the component supply chuck moves downward, and positions the electronic component. and a component supply chuck body having a pair of movable fingers that can freely hold electronic components received at the component receiving section; and a component supply chuck drive mechanism that moves the component supply chuck body upward in conjunction with movement of a component positioning slider.

A roller 40 is attached to one end of the rotating lever 39, and the roller 40 is in rolling contact with the roller rolling contact stopper 36. It is rotatably connected in a fitted state. The tip of a cylinder rod 42 of an air cylinder 41 is rotatably attached between one end of the rotary lever 39 to which the roller 40 is attached and the pivoted bent portion of the rotary lever 39 via a connector 42a. It is being The base end of the air cylinder 41 having a cylinder rod 42 is rotatably connected to a cylinder support bracket 43 provided on the base 5. Therefore, in this embodiment, the component supply chuck drive mechanism that drives the component supply chuck 19 in the vertical direction and the component positioning slider drive mechanism that drives the component positioning slider 33 in the horizontal direction are the rotating lever 39. It is integrally formed with an air cylinder 41, and the vertical movement of the component supply chuck and the horizontal movement of the component positioning slider 33 are linked by rotation of the rotation lever 39.

Next, the action will be explained.

First, a large number of electronic components 15 are supplied to the shooter 4 and the horizontal shooter 10 from the stack magazine 3. Furthermore, without operating the air cylinder 41, the component supply chuck 19 is compressed by the compression spring 2.
The electronic component 15 is moved upward by the biasing force 5, and the component receiving portion 22 closes the component ejection port 14 of the horizontal shooter 10 to prevent the electronic component 15 from falling. At this time,
The component positioning slider 33 is a tension spring 3
The tip of the guide plate 34 attached to the component positioning slider 33 is not positioned directly above the component supply chuck 19.

Next, when the air cylinder 41 is operated to extend the cylinder rod 42, the rotating lever 39 is rotated clockwise to the position shown by the solid line, as shown in FIG. Accordingly, the component supply chuck 19 connected to one end of the rotating lever 39 via the lever mounting plate 20 and the movable slider 18 is moved down, and the component receiving section 22 faces the component ejection port 14. At the same time, the component positioning slider 3 has a roller rolling stopper 36 that presses against a roller 40 provided at the other end of the rotating lever 39.
3 is moved toward the parts supply chuck 19 side, and the tip of the guide plate 34 is moved toward the parts supply chuck 19 side.
That is, it is located directly above the component receiving section 22.

Then, when the parts receiving section 22 faces the parts ejecting port 14, the parts receiving section 2
The electronic components 15 in the horizontal shooter 10 are delivered to the terminal 2. When the electronic component 15 is delivered, the tip of the guide plate 34 is positioned directly above the component receiving section 22, so that the electronic component 15 is prevented from flying upward from the component receiving section 22. The positioning of the component 15 is reliably performed. Furthermore, the stopper 24 prevents the electronic component 15 from flying out from the component receiving section 22 in the advancing direction.

In this way, when the electronic component 15 is positioned and placed on the component receiving section 22, the piston 28 is moved by the introduction of air, and the pair of open movable fingers 23, 23 is urged in the expanding direction. The electronic component 15 is closed against the elasticity of the spring 27, and the electronic component 15 is held in the component receiving portion 22 by a pair of movable fingers 23, 23.

After that, when the operation of the air cylinder 41 is stopped, that is, the air is vented, the component supply chuck 19, which is in the lower position, is moved upward by the biasing force of the compression spring 25, and the component supply chuck 19 is moved upwardly by the biasing force of the compression spring 25.
The component positioning slider 33 on the side is slid toward the shooter 4, the pivot lever 39 is pivoted counterclockwise, and the cylinder rod 42 is withdrawn. Therefore, at this time, the tip of the guide plate 34 is also moved away from the position directly above the component supply chuck 19, and the component supply chuck 19 is moved away from the movable finger 2.
3 moves upward while holding the electronic component 15.

At the same time, the insertion head 8 of the electronic component insertion machine 1 is moving to a position directly above the component supply chuck 19, and when the component supply chuck 19 reaches the upper position, the electronic component 15 is directly inserted into the insertion chuck. Passed to 8a. Thereafter, the insertion chuck 8a moves and inserts the electronic component 15 into the printed circuit board placed on the printed circuit board support device 6.

On the other hand, when the electronic component 15 is transferred from the component supply chuck 19 to the insertion chuck 8a, the air cylinder 41 is operated again, the rotation lever 39 is rotated clockwise, and the component supply chuck 19 is moved downward. At the same time, the component positioning slider 33 is moved toward the component supply chuck 19 side. At this time, the movable finger 23 has already been opened. Then, electronic components 15 are transferred to the component receiving portion 22 of the component supply chuck 19 that has been moved down from the component ejection port 14 of the horizontal shooter 10.
is being passed on.

Thereafter, similar operations are repeated, and the electronic components 15 are successively transferred from the shooter 4 to the insertion chuck 8a.

In this embodiment, a component supply chuck drive mechanism that drives the component supply chuck 19 and a component positioning slider drive mechanism that drives the component positioning slider 33 are connected to the rotary lever 39 and the air cylinder 4.
Although the two drive mechanisms are integrally formed, it goes without saying that they may be formed separately as long as they are driven in conjunction with each other.

As explained above, according to this idea,
The configuration includes an inclined shutter that has a component ejection port at the lower end and supplies electronic components, and a tilted shutter that receives the electronic components that have been supplied to the lower end of the shutter from the component ejection port and is movable in the vertical direction. a component supply chuck which holds and transfers the electronic component to the insertion chuck during upward movement; and a component positioning slider that moves in conjunction with the vertical movement of the component supply chuck, and advances to a position directly above the component supply chuck to position the electronic component when the component supply chuck moves downward, and the component supply chuck is connected to the component ejection port. a component supply chuck body having a component receiving section that receives electronic components from the component receiving section; a component supply chuck body having a pair of movable fingers that can freely hold the electronic components received by the component receiving section; and a component supply chuck body that is linked to the movement of the component positioning slider. Since the component feeding device of the electronic component insertion machine is equipped with a component supply chuck drive mechanism that moves the component supply chuck up and down, when the electronic component is transferred from the computer to the component supply chuck, the electronic component is moved by the component positioning slider. When electronic components are positioned and transferred securely, and further transferred from the component supply chuck to the insertion chuck of the electronic component insertion machine,
The component supply chuck is moved upward by the component supply chuck drive mechanism, and when the component supply chuck is moved upward, the movable fingers are holding the electronic components placed on the component receiving section. The electronic components can be reliably delivered, and the electronic components can be delivered more simply and smoothly compared to the conventional method.
