Description

Detailed Description of the Invention [Industrial Field of Application] The present invention provides an electrode material coating device for coating an electrode material on an element, in which a large number of elements and a coating screen are connected together.
This invention relates to a nine-electrode material coating and setting device that automatically aligns and arranges a large number of devices on a flat 11tllii material coating jig.

[Conventional technology]

Conventional It electrode material coating equipment has been used to coat a large number of electrode material pastes, for example 16 pieces, at one time when applying an electrode material paste to a fired body of a piezoelectric element (hereinafter referred to as an element). 16
In order to align the 16 elements with the electrode material application screen, there is one in the electrode material application jig which has been machined with highly precise recesses that can accommodate 16 elements.

A worker used to set and apply the product by hand, but it took a lot of time, and on top of that, the machining of the jig required precision of 1.
There was a drawback that the electrode material application jig was expensive.

[Problem that the invention seeks to solve]

In view of the above-mentioned circumstances, the present invention determines the position of the element by the position of the through hole of the holder in which the element is stored.
sThe elements placed horizontally are transferred onto the jig using an air chuck.The jig is a flat plate without any processing that requires precision, and each element is set into the recess of the jig by hand. There is no need to do this, and the jig can be a flat plate, reducing costs and speeding up the electrode material application process.

[Means for solving problems]

The invention will be explained with reference to the drawings.

Conventional jig IK is one in which a large number of elements 2, for example 16, are lined up.Jig A1 is placed on top of the electrode material coating device 3, and after placement, the cables 2 are placed in the recesses 12 of the jig 1 by hand. Set it up, friend.

After setting element 2 on jig 1, print screen 4
The IC@ is sent to the IC@, silver paste (electrode material) is applied, and it returns to its original position.

The automatic electrode material application device 3 is divided into an electrode material application section 5 and a drying oven 6, and the jig 1 is I! The electrode material is applied at the electrode material application section, returned to the original position 9, and then sent to the drying oven 6KI1.

The electrode material application section 5 is moved to the drying oven 6 by one reciprocating movement.
The movement is in one direction, and the jig 1 that has passed through the furnace 6
The element 2 is then taken out, the element 2 is turned over, an electrode material is applied to the back surface, and then the element 2 is moved to the drying oven 6.

In the present invention, in such an electrode material coating device 3, the jig 1 does not have a recess 12, and when arranging the elements 2 on the flat jig l, the position of the elements 2 can be determined with high accuracy using the holder 7. 7 is as shown in the first vlJK. That is, the holder 7 is a box shaped like a rectangular parallelepiped, and a through hole 8 corresponding to the size of the element 2 is bored with high accuracy, and the accuracy of the hole 8 corresponds to the arrangement accuracy of the element 2. Further, the number of holes 8 corresponds to the number of arrays of cords 2. A step 9 of the element 2 is formed in the lower part of the hole 8, and the element 2 is stopped by the stopper, and the element 2 is accumulated thereon. A hole 10 is drilled in the stopper, and a push-up rod 11 of the element 2 which can move up and down is inserted into the hole 10, and when the element 2 is sucked one by one from the upper part of the hole 8 by the air chuck, It has a structure in which the suction member 2 is pushed up downward and the suction is always carried out at a constant height. Therefore, the element 2 is always placed in a fixed position at the upper end of the hole 8.

For example, the height of the element 2 is detected by a sensor, and the push-up rod 11 is adjusted until a certain height is achieved.

In the present invention, the element 2 is sucked up from the upper surface of the holder 7 using an air chuck, the element 2 is placed on a jig 1 shown in FIG. The elements 2 are sucked up and stored in another holder 7. Next, the cords 2 stored in the holder 7 are turned over and an electrode material is applied to the back side of the element 2.

Although the air chuck is not shown, it is used to suck up air using a vacuum, and commercially available vacuum assemblies are required for the number of elements 2, and the arrangement must be the same as that of elements 2.
It must be accurate and accurate.

〔Effect of the invention〕

The present invention consists of a holder holder and a conveying device mainly consisting of an air chuck that sucks up the nine elements 2 accumulated in the holder 7. The air chuck sucks up the elements and places them on a jig. 8 is the same arrangement, and the element sucked up through the hole 8 of the holder is directly transferred onto the jig 1, so the jig AIK
A flat plate can be used without machining the recesses 12, etc., and the work of arranging the elements 2 one by one by hand is eliminated, and a large number of elements can be transported at the same time with high precision using an air chuck. The coating process has become more than twice as efficient as the conventional process. The Maku jig uses a flat plate to keep the initial cost of the jig low, and compared to the conventional bamboo and chisel method, it is possible to rationalize and improve the efficiency of the equipment and lower the cost of the jig type.
