Description

Technical Field

[0001] This utility model belongs to the field of chip testing technology, specifically a flipping platform for chip testing. Background Technology

[0002] With the increasing complexity of electronic devices and the rapid development of integrated circuit technology, chip quality control and reliability testing have become an indispensable part of the electronics manufacturing industry, especially in the testing process after chip packaging.

[0003] Surface inspection of chips, especially the quality inspection of the front and back sides of chips, is crucial to the reliability of chips. Packaged chips often have various problems, such as surface cracks, poor solder joints, and misaligned pins. Traditional inspection equipment can usually only observe chips from a fixed angle or direction, and operators have to manually flip the chips. Due to the small size of chips, the back inspection process is extremely troublesome. Therefore, we propose a flipping platform for chip inspection. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides the following technical solution: a flipping platform for chip inspection, comprising a first fixed frame, a motor mounted on the first fixed frame, an output shaft mounted at the output end of the motor, the output shaft rotatably passing through a second fixed frame, a flipping plate mounted on the output shaft, and an observation component mounted on the flipping plate.

[0005] The observation assembly has four sets, which are symmetrically arranged in pairs on the front and back of the flip plate. The four sets of observation assemblies are respectively arranged on both sides of the output shaft. The observation assembly includes a frame, in which a chip slot is provided. The chip slot passes through the flip plate. A rotating shaft is provided on the flip plate. A cover plate is rotatably provided on the rotating shaft. A buckle is provided on the inner side of the end of the cover plate away from the rotating shaft. A slot is provided on the flip plate, and the buckle matches the slot.

[0006] Preferably, there are two second fixing frames, which are symmetrically arranged along the output shaft axis. The flip plate is disposed between the two second fixing frames. This design can provide more stable support and prevent the flip plate from shaking when rotating.

[0007] Preferably, there are multiple chip slots, which are equidistantly distributed within the frame. This helps to improve the efficiency of chip detection, is suitable for detecting multiple chips simultaneously, improves work efficiency, and ensures that the chips do not interfere with each other or become misaligned.

[0008] Preferably, the chip slot is a square slot, which is suitable for chips with a maximum size of 40mm×40mm, and is suitable for most standardized chips, avoiding designs that are too broad or unsuitable for certain specific chips.

[0009] Preferably, the second fixing frame has a through hole, and a ball bearing is installed in the through hole. The output shaft passes through the ball bearing, which effectively reduces friction and improves the rotational efficiency and stability of the output shaft.

[0010] Preferably, the cover plate is provided with a handle, which makes it convenient for operators to open and close the chip slot, thereby improving the ease of operation.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The operator opens the front cover and places the chip to be inspected into the chip slot on the flip plate. The back cover remains closed to prevent the chip from falling during placement. The flip plate remains horizontal. The operator manually or using inspection equipment inspects the front of the chip for cracks, scratches, or other defects. After the front inspection is complete, the operator closes the front cover, the motor starts, and the output shaft rotates, causing the flip plate to rotate and flip the chip to the back. During rotation, the cover locks to the slots via latches to ensure the chip is securely fixed and prevent displacement or damage during flipping. Once the flip plate reaches the correct position, the chip enters a new horizontal position. The back cover is then opened, exposing the other side of the chip for back inspection. After both sides are inspected, the chip is removed from the chip slot. Defective chips are placed separately for screening or rework. Inspected chips can be sent to subsequent production stages, and the next batch of chips to be inspected is placed in. Repeating these steps automatically flips the chips to the front and back for inspection, reducing the need for manual intervention and improving inspection efficiency. Attached Figure Description

The output shaft 3 rotatably passes through a second fixed frame 4. A flip plate 5 is mounted on the output shaft 3, and an observation component is mounted on the flip plate 5.

[0022] The observation assembly has four sets, which are symmetrically arranged in pairs on the front and back of the flip plate 5. The four sets of observation assemblies are respectively arranged on both sides of the output shaft 3. The observation assembly includes a frame 11, in which a chip slot 6 is provided. The chip slot 6 passes through the flip plate 5. A rotating shaft 7 is provided on the flip plate 5. A cover plate 8 is rotatably provided on the rotating shaft 7. A buckle 9 is provided on the inner side of the end of the cover plate 8 away from the rotating shaft 7. A slot 10 is provided on the flip plate 5. The buckle 9 matches the slot 10.

[0023] There are two second fixing frames 4, which are symmetrically arranged along the output shaft 3. The flip plate 5 is arranged between the two second fixing frames 4. This design can provide more stable support and prevent the flip plate 5 from shaking when rotating.

[0024] There are multiple chip slots 6, which are equidistantly distributed within the frame 11. This helps to improve the efficiency of chip detection, is suitable for detecting multiple chips at the same time, improves work efficiency, and ensures that the chips do not interfere with each other or become misaligned.

[0025] Chip slot 6 is a square slot, which is suitable for chips with a maximum size of 40mm×40mm. It is suitable for most standardized chips and avoids designs that are too broad or unsuitable for certain specific chips.

[0026] The second fixed frame 4 has a through hole, and a ball bearing 12 is installed in the through hole. The output shaft 3 passes through the ball bearing 12, which effectively reduces friction and improves the rotation efficiency and stability of the output shaft 3.

[0027] The cover plate 8 is equipped with a handle 13, which makes it convenient for operators to open and close the chip slot 6, improving the ease of operation.

[0028] Working principle: The operator opens the front cover 8 and places the chip to be tested into the chip slot 6 on the flip plate 5. At this time, the back cover 8 remains closed to ensure that the chip will not fall during placement. The flip plate 5 remains in a horizontal position. The operator manually or uses testing equipment to inspect the front side of the chip for cracks, scratches, or other defects. After the front side inspection is completed, the operator closes the front cover 8, the motor 2 starts, and the output shaft 3 begins to rotate, driving the flip plate 5 to rotate and flip the chip to the back side. During the rotation, the cover 8 is locked to the slot 10 by the buckle 9 to ensure the chip is stably fixed and to prevent displacement or damage during the flipping process. After the flip plate 5 rotates to the appropriate position, the chip enters a new horizontal position. The back cover 8 is then opened, exposing the other side of the chip for back side inspection. After the front and back sides of the chip are inspected, it is removed from the chip slot 6. Unqualified chips are placed separately for screening or rework. The inspected chips can be sent to the subsequent production stage, and the next batch of chips to be tested is placed in. The above steps are repeated to automatically flip the chips to the front and back sides for inspection, reducing the need for manual intervention and improving inspection efficiency.
