Description
Technical Field
[0001] The invention relates to the technical field of ITO target materials, in particular to a tooling fixture for polishing an ITO target material. Background Art
[0002] ITO target material is a black-gray ceramic semiconductor formed by mixing indium oxide and tin oxide powder in a certain proportion and then processing and shaping through a series of production processes, and then sintering in a high-temperature atmosphere (1600 degrees, sintering with oxygen). ITO film uses ITO target material as raw material, and the ITO target is gasified and sputtered onto a glass substrate or a flexible organic film through magnetron sputtering. ITO film has conductivity and light transmittance, and the thickness is generally 30 nanometers to 200 nanometers. After the ITO target material is sintered, it will be deformed to a certain extent, so it needs to be cut and plane-polished accordingly to achieve the size required by the customer. After the target material is cut, there will be cutting marks on the side, so it needs to be polished. In the polishing process, the ITO target material needs to be clamped and fixed by a fixture.

[0038] Two groups of position-limiting support frames 54 are provided and symmetrically distributed on both sides of the pressure rod 51 , and the bottom of the position-limiting support frames 54 is fixedly connected to the top of the placement table 3 .
[0039] The fixed slide 57 and the movable slide 59 are both arranged on the control circuit of the electric push rod 52 , and the bottom of the return spring 55 is fixedly connected to the inner wall of the device groove 7 .
[0040] The anti-skid device 56 includes an anti-skid plate 561, an arc-shaped groove 562 is provided on the top of the anti-skid plate 561, an anti-skid airbag 563 is installed inside the arc-shaped groove 562, a friction pad 564 is installed on the top of the anti-skid airbag 563, a groove 565 is provided at the center of the anti-skid plate 561, an air storage bag 567 is installed inside the groove 565, and the air storage bag 567 is evenly connected to a control valve 568.
[0041] There are multiple groups of arc-shaped grooves 562 evenly distributed on the anti-slip plate 561 , and there are multiple groups of friction pads 564 evenly distributed on the anti-slip airbags 563 .

The anti-skid air bag 563 is provided with multiple groups. The bottom of the anti-skid plate 561 is fixedly connected to the top of the contact plate 58.
[0043] When in use, the ITO target to be polished is placed on the placement table 3, the electric push rod 52 drives the pressure rod 51 to move, and the placed target is squeezed and fixed by the squeezing plate 53. The target is placed on the anti-skid device 56 to squeeze the reset spring 55, and the reset spring 55 is compressed into the device groove 7 by force.

[0044] Open the control valve 568 to discharge the gas inside the air storage bag 567 into the anti-skid air bag 563. The air pressure inside the anti-skid air bag 563 increases, and the gas increases, gradually expanding and deforming. After the expansion and deformation, the anti-skid air bag 563 uses the friction gasket 564 to squeeze the target material on the top, increasing the friction between the target material and the target material, effectively preventing the target material from slipping and falling off during grinding, thereby improving the grinding accuracy.
