Description

Technical Field

[0002] An automatic die sorter is a high-precision automated device used in the back-end processes of semiconductor manufacturing. It is mainly used for testing, sorting, and classifying chips (dies) on wafers.

[0003] Existing sorting and testing equipment uses a robotic arm to pick up chips and place them on a testing station for inspection. Based on the inspection results, the chips are sorted and arranged. However, existing sorting equipment typically only tests one chip at a time at a single testing station. To improve inspection efficiency, more testing stations are needed. In addition, the sorting and arrangement of chips is mostly done using an integrated container divided into multiple small compartments for zoned placement. While this facilitates unified collection and use, it is not convenient for sorting and selecting chips according to actual needs, which affects production efficiency to some extent. Therefore, an eight-station automatic die sorting machine is proposed to solve the problems existing in the current technology. Utility Model Content

The bottom of the waffle box is made of magnetic material and is attracted and fixed by magnets. At the same time, it is constrained by the pressure block and the compression spring provides a fastening force to ensure that the waffle box will not shift when grasped or placed.

[0030] More specifically, the dual-chip fixing mechanism 9 includes a fixed lifting motor 91, a lifting slider 92, and a lifting guide rail 93. The fixed lifting motor 91 is installed at the end of the lifting guide rail 93. The lifting guide rail 93 is provided with two guide rails that are slidably connected to the lifting slider 92. The output shaft of the fixed lifting motor 91 is connected to the lifting slider 92. The dual-chip fixing mechanism is a lifting mechanism that descends first when the chip is placed, making it easier to place the chip. The fixed lifting motor drives the lifting slider to move on the lifting guide rail. The lifting guide rail has a dual-guide rail structure, making the movement of the lifting slider on the dual guide rails more stable.

[0031] The lifting slider 92 is provided with a fixed seat mounting column 94, and a fixed seat 95 is installed on the top of the fixed seat mounting column 94. The lifting slider moves the fixed seat mounting column under the drive of the lifting drive motor, thereby driving the fixed seat to rise and fall.

[0032] The top of the mounting base 95 is provided with two vertical chip fixing slots 96. The two chip fixing slots can place and fix two chips. The chip fixing slots are provided with multiple suction holes (not shown). The mounting base is provided with a vacuum suction tube (not shown) corresponding to the suction holes.

The output end of the front and rear linear drive motor 61 is connected to a transmission screw and threadedly connected to the drive nut. In this embodiment, the horizontal and forward / backward movement of the gripping mechanism on the machine base is achieved by setting two linear drive motors.

[0038] More specifically, the microscope inspection mechanism 2 includes a microscope 21, a microscope support 22, and a microscope moving guide rail 23.

[0039] The working principle of this utility model is as follows: The material area 5 is symmetrically divided into a feeding area 51 and a collection area 52. The left side is the feeding area 51, and the right side is the collection area 52. The material to be tested is placed in the feeding area on the left. The main control system is integrated into the machine base 1 and is specifically controlled through the button area 12 on the front side of the machine base. The detection and sorting scheme is set in the main control system. After the equipment is started, the front and rear linear drive mechanisms 6 perform self-checks and return to the initial position, i.e., the end position. The horizontal drive mechanism 7 also performs self-checks and drives the gripping mechanism 8 to move to the leftmost position. Then, it starts working according to the settings of the main control system. The gripping mechanism 8 picks up the chip from the feeding area. After the gripping is completed, the front and rear linear drive mechanisms 6 and the horizontal drive mechanism 7 are restarted, driving the gripping mechanism 8 to move forward. Depending on the detection item, it moves to different dual-chip fixed detection stations 4 in front. Since the gripping mechanism 8 has four push plates 84, which are driven to lift by dual lifting motors 81, four suction nozzles can be used. The connecting tube 85 picks up and places materials, operating on four chips at a time. The fixing seat 95 is equipped with two fixing slots 96, fixing and testing two chips at a time. After placing one chip on the fixing seat 95, it moves to the next station to place the remaining two chips. The simultaneous picking up of four chips greatly improves the material handling efficiency. During testing, the detection mechanism 10 adjusts its specific position through multiple adjusting bolts to ensure accurate movement above the fixing slot 96. The visual recognition camera 83 takes pictures of the chip for recognition, ensuring accurate placement and comparing the test items. The detection probe card 109 performs specific tests on the chip. During and after the test, the chip can be observed through the moving microscope detection mechanism 2. The program can be corrected in real time based on the observation to obtain the specific sorting requirements. After the test, the gripping mechanism 8 picks up the chip and places it into the waffle box 3. Different waffle boxes 3 can be removed as needed.
