Description

Technical Field

[0001] The utility model relates to the technical field of semiconductor wafers, and particularly relates to an automatic iron ring feeding device for a cassette. Background Art

[0002] An iron ring, namely a wafer ring, also known as a wafer frame ring or a wafer bonding ring, is a commonly used spare part and consumable in the semiconductor industry. It is mainly used to provide support and fixation during the processes of wafer manufacturing, packaging, and transportation. The main function of the iron ring is to support and fix the wafer. During the wafer manufacturing process, the wafer needs to go through multiple steps, such as lithography, electroplating, etc. These steps require the wafer to be kept flat and stable. Especially during operations such as dicing and cutting, the iron ring can fix the wafer to prevent it from moving or being damaged during the processing. This protection measure is crucial for ensuring the quality of the wafer and the performance of subsequent integrated circuits. During the packaging process, the iron ring is used to protect the wafer and assist in completing the packaging steps. During the transportation process, the iron ring is used to ensure that the wafer is not damaged during transportation. Through its structural design and material selection, the iron ring provides the necessary support and fixation for the wafer, ensuring that the wafer will not be damaged, deformed, or moved during the manufacturing, packaging, and transportation processes.

[0003] During the assembly process of the iron ring and the wafer, the iron rings are often placed in a cassette. When the upper cover of the cassette is opened, the iron rings inside will be skewed for various reasons and cannot be evenly spaced. Before the iron rings are taken out of the cassette, the existing method is to manually install an iron ring feeder so that the iron rings can be separated one by one in the cassette, maintaining a certain distance, and then mechanically pick up the materials automatically. However, manually installing the iron ring feeder is rather cumbersome and time-consuming, which affects the production cycle of the product. In addition, due to manual installation, the consistency of the installation position cannot be guaranteed, which may lead to poor separation of the iron rings, resulting in alarms and shutdowns in subsequent processes, and even damage to the product, thus affecting the product yield and production efficiency.

[0024] In this application, the iron ring feeding mechanism 4 includes a fixed plate 41 which is horizontally installed on the frame 1. A horizontally arranged air cylinder 42 is provided on the fixed plate 41. The piston rod of the air cylinder 42 is connected to a first mounting plate 43 which is horizontally arranged front and back.

[0029] Based on the above solution, two triangular plates 33 are connected between the lower part of the placement plate 31 and the connecting plate 32, which are used to support the placement plate 31 and ensure the stability of the placement plate 31. A second limiting plate 36 is provided below the connecting plate 32, which is used for limiting the descending position of the placement plate 31 and ensuring the safety and stability of the device.

[0030] Based on the above solution, a plurality of oblong holes are provided on the positioning plate 35 at intervals in the front and rear directions, which are used for adjusting the position of the positioning plate 35, ensuring accurate positioning of the position of the cartridge 5, and at the same time being able to position cartridges 5 with different width dimensions.
