Description

Technical Field

[0001] The utility model relates to a detection device for preventing misoperation of semiconductor chips, which is applicable to the technical field of semiconductor chip detection. Background Art

[0002] X-Ray inspection is an inspection process in the semiconductor chip packaging process. After the substrate of the semiconductor chip is plastic-sealed, it is impossible to judge whether the internal chip is qualified only by human eyes. Therefore, X-Ray inspection equipment is needed to detect the internal structure through X-rays to evaluate the chip quality. However, due to the special material or structure of some chips, they will be damaged by X-ray irradiation. Therefore, the chip substrates need to be sorted before this process. In the prior art, it is usually sorted manually according to the material information written in the material flow corresponding to the substrate, and the chip substrates that cannot be inspected by X-Ray are picked out. However, manual sorting will generate a lot of labor costs and low efficiency. On the other hand, the sorting personnel are easily fatigued or distracted during long-term work, which will reduce the sorting accuracy, resulting in some chips being damaged or missed, which will not only cause cost waste, but also reduce the product yield. Utility Model Content

[0003] In order to solve the defects of the prior art mentioned above, the utility model proposes a detection device for preventing misoperation of semiconductor chips.

[0004] The technical solution adopted by the utility model is: a detection device for preventing misoperation of semiconductor chips, including a scanning mechanism for reading two-dimensional code information attached to a detected object, a main control mechanism connected to the scanning mechanism, and a detection mechanism connected to the main control mechanism, the scanning mechanism including a base, a pair of guide edges arranged on the base and extending from one end of the base to the other end and used to limit the position of the detected object, a scanner arranged at the other end of the base and used to scan the two-dimensional code, a position sensor for detecting the position of the detected object on the base is arranged on the base, and the height of the position sensor is lower than the guide edge; the detection mechanism includes a test box with a box door, and a door control module for locking or unlocking the box door, and the main control mechanism is connected to the door control module. When testing the part to be tested, insert it from the other end of the base between a pair of guide edges, so that the part to be tested is fixed on the top of the base, and then the QR code on the part to be tested is scanned by the code scanning mechanism to read its material information, and then the main control mechanism compares the material information to determine whether the part to be tested can be tested by X-Ray. If it cannot be tested, the main control mechanism controls the access control module to lock the door to prevent the operator from putting chips that cannot be tested by X-Ray into the test box. Otherwise, the door is unlocked to facilitate the operator to test. Through the cooperation of the code scanning mechanism, the main control mechanism and the detection mechanism, the detection device can automatically control the locking or unlocking of the test box door according to the QR code information of the part to be tested, which not only improves the detection efficiency and reduces the cost, but also avoids the wrong detection or missed detection caused by the fatigue or distraction of the detection personnel, ensures the detection accuracy, avoids the waste of cost, and improves the product yield.

[0005] Furthermore, the main control mechanism includes a human-computer interaction module connected to the barcode scanner and the position sensor at one end, a computing module connected to the other end of the human-computer interaction module at one end, and a controller connected to the other end of the computing module at one end, and the other end of the controller is connected to the access control module. Specifically, the human-computer interaction module is set as a display, and the human-computer interaction module is convenient for the detection personnel to operate the detection process. For the detected parts that fail to scan the barcode, the detection personnel can manually input the information of the detected parts through the human-computer interaction module, and can intuitively feedback the information through the human-computer interaction module to improve convenience; the QR code information of the detected parts is analyzed and compared through the computing module to determine whether the detected parts can be subjected to X-Ray detection, and at the same time, the controller sends instructions to the access control module to control the locking or unlocking of the test box door.

[0006] Furthermore, a U-shaped slot is provided on the base, and a pair of guide edges are respectively provided on the inner walls on both sides of the U-shaped slot. The U-shaped slot and the guide edges facilitate the operator to insert and remove the detected part for scanning, thereby improving the scanning efficiency.

[0007] Furthermore, the position sensor is arranged in the U-shaped slot, and the position sensor is located at the end of the U-shaped slot close to the other end of the base. When the detected part is plugged into place, it will block the position sensor, thereby triggering the position sensor to send a plug-in signal, which is convenient for the barcode scanner to scan the code, without the need to manually open the barcode scanner, reducing the operation steps and improving efficiency.

[0008] Furthermore, the code scanning mechanism also includes a support frame fixed to the other end of the base, the upper part of the support frame is inclined from the other end of the base to the one end thereof from bottom to top, and the code scanner is fixed to the upper part of the support frame. The code scanner is fixed by the upper inclined support frame, so that the distance and angle between the code scanner and the detected part are fixed, and the operator only needs to repeatedly plug and unplug the detected part to quickly and conveniently complete the code scanning operation, thereby improving the convenience, efficiency and success rate of the code scanning operation.

[0009] Furthermore, the angle between the upper portion of the support frame and the surface of the base is 25

[0010] °~40°, the appropriate angle enables the scanner to quickly and error-freely identify the QR code on the inspected object, further improving the convenience, efficiency and success rate of the scanning operation.

[0011] Furthermore, a disassembly groove connected to the U-shaped slot is provided on the upper surface of the other end of the base, the dimension of the disassembly groove perpendicular to the guide edge is smaller than the dimension of the U-shaped slot perpendicular to the guide edge, and the depth of the disassembly groove is smaller than that of the U-shaped slot. The disassembly groove facilitates the inspection personnel to quickly and conveniently remove the inspected part after scanning the code, thereby improving the operation efficiency.

[0012] Due to the application of the above technical solution, the utility model has the following advantages compared with the prior art:

[0013] The detection device for preventing misoperation of semiconductor chips in the utility model cooperates with the code scanning mechanism, the main control mechanism and the detection mechanism, so that the detection device can automatically control the locking or unlocking of the test box door according to the two-dimensional code information of the detected part, which not only improves the detection efficiency and reduces the cost, but also avoids the wrong detection or missed detection caused by the fatigue or distraction of the detection personnel, ensures the detection accuracy, avoids the waste of cost, and improves the product yield.
