Description

Technical Field

[0001] The utility model relates to the technical field of wafer picking, in particular to a wafer picking workbench. Background Art

[0002] During the semiconductor manufacturing process, after wafer lamination, dicing, and expansion, good chips are picked and placed into designated chip cassettes. The diced wafers are adhered to a sticky blue film and then covered with an expansion ring. Dies are formed on the film surface with a certain spacing. Operators manually use a suction pen to pick up the chips and place them into a tray.

[0003] When the existing staff performs the wafer picking operation, they need to hold the wafer ring with one hand and use the fingers of the same hand to push out the die, and then use the other hand to hold the suction pen to pick up the die, which is difficult for the personnel to operate. In addition, manual material removal can easily cause damage to the chip. If the operation of picking the wafer is difficult, it is more likely to cause human error, resulting in an increase in the defective chip rate.

[0004] For example, the Chinese authorized patent with announcement number CN 213650389 U (a wafer picking table): it uses a support table and a spring-pressing component to fix the wafer, which can free up one hand of the operator. There is no need to hold the wafer while ejecting the grains. After fixing the wafer with the wafer picking table, the operator can eject the grains on the fixed wafer with one hand and use the other hand to hold the suction pen to absorb the grains. And the tray is set on one side of the support table, which shortens the moving distance of the grains. The wafer picking table has a simple structure, but it greatly facilitates the wafer picking operation of the staff, reduces the time for staff to pick wafers, and reduces the impact of staff's wafer picking operation errors on the chip yield. This technical solution solves the above problems;

[0005] However, the technical solution of the utility model still has some technical problems. When the wafer picking workbench is in use, the staff needs to remove the grains from different positions on the wafer. It is inevitable that the staff needs to frequently change the position of their hands to remove the grains from different positions on the wafer. Moving the hands for a long time and at a high frequency will make the staff easily feel tired, which will seriously affect the staff's work efficiency and work accuracy.

[0006] To this end, a wafer picking workbench is proposed. Utility Model Content

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] See also Figure 1-4 The utility model provides an embodiment of a wafer picking workbench, comprising a main plate 1:

[0027] The connecting rod 2 is fixedly mounted on one side of the main body plate 1, and the upper end of the connecting rod 2 is slidably mounted with an adjusting rod 3 through a card slot. The interior of the upper end of the connecting rod 2 is threadedly mounted with an adjusting screw 17. One end of the adjusting rod 3 is fixedly mounted with an arc bracket 4. Several rotating rollers 5 are rotatably mounted inside the arc bracket 4. Installing the arc bracket 4 can clamp the wafer body 6 to prevent the wafer body 6 from shaking. At the same time, rotating rollers 5 are installed inside the arc bracket 4 to make the wafer body 6 roll more smoothly inside the arc bracket 4, which is convenient for the staff to perform crystal picking operations. Connecting brackets 7 are fixedly mounted on both ends of the outside of the arc bracket 4. Plastic brackets 8 are rotatably mounted inside the connecting bracket 7. Installing the plastic bracket 8 can support the wafer body 6 to prevent the wafer body 6 from shaking and ensure the stability of the device clamping the wafer body 6. The interior of the upper end of the connecting bracket 7 is threadedly connected with a friction adjusting bolt 19.

[0028] The movable bracket 9 is arranged inside the other side of the upper end surface of the main plate 1. The upper end of the movable bracket 9 is rotatably installed with a positioning roller 11 through a bearing. The installation of the positioning roller 11 can drive the wafer body 6 to rotate, so that the staff does not need to move their hands frequently, and the wafer body 6 is rotated to a certain angle so that the grains on its upper end can automatically approach the staff's hands. The staff only needs to move their arms slightly regularly to remove the grains on the upper end of the wafer body 6, which effectively avoids the staff's fatigue and ensures the staff's work efficiency and work accuracy. A propulsion spring 12 is fixedly installed on the side of the movable bracket 9 away from the connecting rod 2.

[0029] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , collecting baskets 16 are installed on the front and rear end surfaces of the main body plate 1, and limiting cylinders 18 are fixedly installed on the front and rear end surfaces of the lower end of the main body plate 1, and the limiting cylinder 18 is connected to the collecting basket 16 through a slot. The lower end surface of the main body plate 1 is installed with an electric telescopic rod 14, which is fixedly connected to the main body plate 1. The installation of the electric telescopic rod 14 can adjust the height of the main body plate 1, so that the main body plate 1 can be closer to the staff, so that the staff can have a more comfortable posture to perform crystal picking work, making the device more humane. The lower end surface of the electric telescopic rod 14 is installed with a supporting base 15, and the supporting base 15 is fixedly connected to the electric telescopic rod 14. The upper end of the interior of the mobile bracket 9 is fixedly installed with a driving motor 10, and the rotating driving part of the driving motor 10 is fixedly connected to the positioning roller 11. The front end on the other side of the upper end surface of the main body plate 1 is installed with a controller 13, which is connected to the main body plate 1 by screws, and the wafer body 6 is provided on the inner side of the arc bracket 4.

[0030] Working principle: When in use, the staff pulls open the positioning roller 11 and places the wafer body 6 inside the arc-shaped bracket 4 so that the outside of the wafer body 6 contacts the rotating roller 5. Then the staff rotates the plastic bracket 8 so that the plastic bracket 8 rests against the outside of the wafer body 6. Then the staff stops applying tension to the positioning roller 11. At this time, the propulsion spring 12 pushes the movable bracket 9 to move so that the outside of the positioning roller 11 contacts the outside of the wafer body 6. Then the staff performs a single crystal picking operation on the wafer body 6. When the staff finishes the single crystal picking operation, the driving motor 10 drives the positioning roller 11 to rotate a certain angle so that the unpicked area on the upper end of the wafer body 6 moves to the upper end of the staff's hand. Then the staff will perform the crystal picking operation again. When the staff has picked all the grains inside a circle area at the upper end of the wafer body 6, the staff will move their hands toward the center of the wafer body 6 by the distance of one grain, and then repeat the above operation to complete all the crystal picking operations on the wafer body 6, effectively avoiding fatigue of the staff and ensuring the work efficiency and accuracy of the staff. Finally, the staff will put the selected grains into the collection basket 16. The electric telescopic rod 14 installed in this device can adjust the height of the main plate 1, so that the main plate 1 can be closer to the staff, so that the staff can have a more comfortable posture to perform crystal picking work, making the device more humane.
