Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a contact piece insertion device for automatically inserting a contact piece of an electric signal switch into a pallet during an assembly process.

Conventionally, a contact piece insertion device has been devised that automatically inserts the contact pieces of an electrical signal switch into a pallet during the assembly process, but it requires two steps: taking out all the contact pieces once and then inserting them into the pallet. Moreover, since the size of the contact piece is small, 1 mm to 2 mm, there are problems in that the use of cams etc. complicates the device, and that it is difficult to position each part of the device in the two steps.

In view of the above drawbacks, the present invention provides a contact piece insertion device that is simple in structure and has high positioning accuracy.

In order to achieve the above object, the present invention provides a silicone for taking out the contact piece and a cylinder for inserting the contact piece to move the holder for taking out the contact piece and inserting it into the pallet, and each cylinder has only one positioning accuracy. This is a configuration that requires the following.

A contact piece insertion device according to an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a front view of a contact piece insertion device according to an embodiment of the present invention;
FIG. 2 is a plan view of the device, and FIG. 3 is a perspective view of essential parts of the device.

As shown in the figure, a contact piece insertion device according to an embodiment of the present invention includes a fixed base 1, an indexing table 2 fixed to the fixed base 1, and an insertion section 3.

The indexing chiffle 2 is equipped with a rotary plate 2ai on the upper part 7, and built-in pallets 4 are fixed at equal intervals on the upper surface of the rotary plate 2a, so that each process of assembling parts can be performed at each position. .

The insertion section 3 includes a plate-shaped bracket 5 and the bracket 5.
A unit 8 and a kneader 8 are provided on one side and transport the contact piece 6 from the previous process to the insertion section 3 through a conveying groove 7.
A contact piece 6 provided in front of the camera and carried by a shooter 8
The upper and lower cylinders (
(not shown) to a predetermined height.
and a drive unit 11 which is provided above the user 8 on one side of the bracket 5 and which takes out the contact piece 6 fed at a predetermined height by the insertion guide 10 and inserts it into the pallet 4 of the indexing table 2. .

The drive unit 11 includes a plate-shaped holding plate 12 provided vertically above the bracket 6, and the holding plate 12 and the bracket 6.
Two vertical shafts 13 are fixed in parallel to the bracket 5 by the lower part of the bracket 5, and a slider 14 that moves up and down on the other surface of the bracket 5 about the vertical shafts 13 is provided. The slider 14 includes a horizontal shaft 16 that slides inside the slider 14 in a state perpendicular to the vertical shaft 13, and two insertion plates 16 provided at one end of the horizontal shaft 15 and placed downward.
The holder 17 is installed parallel to the slider 14, and the cylinder holding plate 14a protrudes perpendicularly to the slider 14, and the movable shaft 19 is fixed horizontally by the joint 18
The insertion cylinder 2Q fixed to 7 and the slider 14
The removal cylinder 21 is fixed horizontally below the insertion cylinder 20 by a cylinder holding plate 14'b that projects vertically.

The operation of this embodiment will be explained below with reference to FIGS. 4 to 7.

As shown in FIG. 4, the contact pieces 6 carried by the conveying grooves 7 of the shooter 802 row are held in the holding grooves 10a of the insertion guide 10. The insertion guide 10 is raised from position A to position B by 1'' so that the contact piece 6 is located at the same height as the insertion plate 16 at position C.

Then, as shown in FIG. 5, the holder 17 is pushed by the movable shaft 24 of the take-out cylinder 21, the insertion plate 16 is moved to the position determined by the take-out cylinder 21, and the contact piece 6 is moved to the insertion plate 16. The contact pieces 6 hold the insertion plate 16 between them.

Then, the insertion guide 1o is lowered to its original position by the upper and lower cylinders 25, and the holder 17 is then moved to the insertion cylinder 2.
0, the insertion plate 16 moves to position E, which is positioned by the adjustment screw 22 shown in FIG.

As shown in FIG. 6, when the slider 14 descends about the lower shaft 13, the insertion plate 16 moves from position B to position F, and the contact piece 6 is placed on the pallet of the indexing table 2. 4 into the holding groove 4a.

Finally, as shown in FIG. 7, the insertion cylinder 20
As a result, the holder 17 returns to its original position with the contact piece 6 inserted into the holding groove 4a of the pallet 4, and the process of inserting the contact piece 6 is completed.

In this way, in this embodiment, when taking out the contact piece 6 from the insertion guide 1Q and inserting the contact piece 6 into the pallet 4, the horizontal positioning, which is an issue of accuracy, is done by using the take-out cylinder 21 and the adjusting screw. 22, the contact piece 6 can be inserted into the holding groove 4a of the pallet 4 reliably with good positioning accuracy without using a complicated structure using a cam etc. An insertion device can be provided.

As described above, the present invention enables the removal and insertion of the contact piece,
By operating with two cylinders, the configuration is simple and the positioning accuracy can be improved.
