Substrate supporting piece

Abstract

The invention discloses a substrate supporting piece which comprises a bush, a lifting pin and at least one bearing mechanism. The bush is provided with a longitudinal through hole penetrating through the two ends of the bush. At least part of the lifting pin is arranged in the through hole, and can move in the through hole in the longitudinal direction. The bearing mechanisms are arranged in the through hole and located on the periphery of the lifting pin to support the lifting pin in a rolling mode. Each bearing mechanism comprises two parallel first bearing pieces and two parallel second bearing pieces, the first bearing pieces are perpendicular to the second bearing pieces, the first bearing pieces and the second bearing pieces are arranged in a staggered mode in the longitudinal direction of the bush, and the lifting pin or the bearing pieces can be prevented from being broken abnormally.

Description

technical field [0001] The invention relates to the field of substrate support, and in particular to a substrate support and a receiving device for supporting a substrate. Background technique [0002] Nowadays, in the manufacturing process of many electronic devices such as OLEDs, operations such as etching, vapor deposition, deposition, coating, etc. need to be performed on a substrate (such as a glass substrate). The equipment for realizing these operations must have a receiving device for supporting the glass substrate. In existing receiving devices for supporting glass substrates, key components (such as support pins and bearings) in the receiving device are often damaged due to the bending of the glass substrate by gravity, which further affects the quality of the above operations.

AI Technical Summary

Problems solved by technology

In the existing structure of the substrate support 2, when the glass is lifted by the lifting pin 21, the entire lifting pin 21 is in an inclined state due to the bending of the glass plate 3 (such as figure 1 shown), the roller 62 in the bushing 22 (as figure 2 Shown) Excessive force on one side

Therefore, the bushing structure in this receiving device will cause the following disadvantages: (1) The inner gap of the bushing is too small, as long as a certain degree of particulate matter is accumulated, the lifting pin will be stuck in the bushing, causing fragments or breaking of the lifting pin ; (2) The volume of the drum is too small, resulting in too small contact area between the lifting pin and the drum. When the lifting pin is tilted, the force point of the drum falls at the right angle between the vertical bearings, which will make it easier to damage the drum or the bearing. It may cause the lifting pin to be stuck and cause fragments, or cause the lifting pin to bend excessively, eventually causing internal damage or even breaking the lifting pin
