Description

Carrier tray receiving device and picking system

The invention relates to a receiving device, in particular to a carrier carrying device and a picking system which can be extracted.

In a semiconductor process, after a wafer is processed by deposition, sputtering, lithography, and etching, the wafer is diced to form a plurality of die, which is a functional electronic component, and then The process of packaging and testing these crystal grains completes the entire semiconductor process.

The cut die is placed in a carrier disk. The carrier structure is a rectangular structure and has a plurality of receiving grooves on the surface thereof for accommodating the cut die to facilitate the transportation of the die. Placement, packaging, and side placement. The action of placing the die on the carrier is called crystallizing, and the action of taking out or placing the die from the carrier is achieved by a chip sorter.

Please refer to FIG. 1A to FIG. CC, which are schematic diagrams of a conventional wafer carrier storage device. In the conventional technique, the wafer carrier storage device 10 is fixed to a carrier 11 and is placed on the corresponding wafer carrier after the wafer has undergone the process of inspection and classification. When the wafer carrier is full and cannot accommodate the wafer, the wafer carrier can be moved to the wafer in the disk storage device by an automated mechanism. Referring to FIG. 1B, the transfer device 12 is moved upward by the bottom side opening of the wafer carrier storage device 10, and a plurality of carrier trays 90 that have been placed on the support member 13 are lifted up and down. Movement allows wafer carrier trays 90 to be stacked in a As a result, a state as shown in FIG. 1C is formed. In the conventional technology, when the wafer carrier trays are stacked to a certain number, it is necessary for the operator to take out the wafer carrier trays stacked on each other to facilitate subsequent storage operations. However, there are a number of problems with the above-mentioned wafer carrier trays that are manually processed. 1. When using manual removal, since the stack of wafer carrier trays has no additional structural protection, the operator is liable to be shaken by fingers or careless. Collision, causing the stacked wafer carrier tray to tip over, causing serious damage.

2. Because there is no frame on the stacked wafer carrier, it is not convenient to carry out any indication to identify the wafer carrier stack of different wafer quality levels, so it is easy to cause misclassification of personnel.

In summary, there is a need for a carrier accommodating device and system to solve the problems caused by conventional techniques.

The third image capturing device can capture the image of the bottom surface of the component 5100 to determine whether the bottom surface of the component 5100 is damaged. Generally, the first image capturing device 512 and the third image capturing device 515 are CCDs. Or a component of CMOS. As for the second image capturing device 514, the image of the carrier 513 can be captured to identify the position of the carrier 513. In addition, the second image capturing device 514 can further capture the image of the component 5100 when the picking component 5110 places the component 5100 on the carrier 513 to determine whether the component 5100 is damaged. In general, the second image capturing device 514 is a component of a CCD or a CMOS.

The carrier tray conveying portions 52 and 53 are connected to the picking portion 51 and the carrier tray accommodating portion 50 to transport the carrier tray 513 of the carrier member 5100. The carrier tray transport portion 52 transports an empty carrier tray so that the pickup member 5110 can place the component 5100. When the carrier 513 is full or is to be stored in the carrier accommodating device 502 in the carrier accommodating portion 50, the carrier tray 53 moves the carrier 513 to the carrier accommodating portion 50. The corresponding carrier disk accommodating device 502 is stored. At this time, the carrier tray conveying portion 52 in turn conveys another empty carrier tray to the positioning to facilitate the pickup member 5110 to place the member 5100. The carrier tray conveying portions 52 and 53 may also be integrated into one conveying portion, which is a conventional technique and will not be described herein.
