Nowadays, the appearance inspection of memory chips is usually carried out using a special inspection device. For the convenience of inspection, the device needs to be able to quickly pick up and put down memory chips.
[0003] Meanwhile, an integrated circuit chip appearance inspection device with application number CN202420328717.8 is disclosed. The device includes a chip appearance inspection equipment. The bottom of the chip appearance inspection equipment has an internal inspection chamber, and a disassembly and assembly assembly is installed on the left side of the inspection chamber. The disassembly and assembly assembly includes a side plate. A retaining plate is embedded in the top of the side plate through a limiting groove. Two reset springs are symmetrically connected to both sides of the bottom of the retaining plate, and the bottom of the reset springs is connected and fixed to the inner wall of the limiting groove of the side plate. The left side of the retaining plate is connected and fixed to a mating plate by bolts.
[0004] However, the following problems were found in the implementation of the relevant technology: Although the existing device can quickly pick up and put in the memory chip, it cannot accurately detect any area of the memory chip as needed when it is detected inside the device, resulting in inaccurate detection. Utility Model Content
[0005] To address the problems mentioned in the background art, this utility model provides a memory chip appearance inspection device that can simultaneously adjust the angles of the memory chip and the camera, as well as the relative height of the camera. The three work together to ensure that the camera can focus on any area of the memory chip, resulting in more accurate inspection results.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a memory chip appearance inspection device, comprising an inspection box and a first servo motor installed at the bottom of the inspection box. The output end of the first servo motor passes through the bottom of the inspection box and is connected to a support plate. An adjustment rod is screwed to the center of the top of the inspection box, and a grip is connected to the top of the adjustment rod. An adjustment frame is installed at the bottom of the adjustment rod via a bearing. A guide post is connected to one side of the top of the adjustment frame, and the guide post is movably inserted into the corresponding side of the inspection box. A second servo motor is installed on one outer wall of the adjustment frame, and the output end of the second servo motor passes through the corresponding side of the adjustment frame and is connected to a camera for inspecting the appearance of the memory chip.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figures 1 to 4 As shown, this utility model provides a memory chip appearance inspection device, including an inspection box 1 and a first servo motor 2 mounted on the bottom of the inspection box 1 via a motor mount. The output end of the first servo motor 2 passes through the bottom of the inspection box 1 and is connected to a support plate 3 by bolts. The top of the support plate 3 is used to place the memory chip. The first servo motor 2 can drive the support plate 3 to rotate by a specified angle to adjust the angle of the memory chip. An adjustment rod 4 is screwed to the center of the top of the inspection box 1, and a grip 5 is connected to the top of the adjustment rod 4 by screws. The grip 5 has a circular structure, which facilitates the application of force to rotate the adjustment rod 4. An adjustment frame 6 is mounted on the bottom of the adjustment rod 4 via a bearing. The rotation of the adjustment rod 4 can drive the adjustment frame 6 to adjust its height. A guide post 7 is threaded to one side of the top of the adjustment frame 6. The threaded connection facilitates disassembly and maintenance, and the guide post 7 is movably inserted into the corresponding side of the inspection box 1. The guide post 7 can restrict the adjustment frame 6 to prevent it from deflecting with the adjustment rod 4, ensuring that the adjustment frame 6 can be raised and lowered smoothly.
[0023] A second servo motor 8 is mounted on one outer wall of the adjustment frame 6 via a motor mount. The output end of the second servo motor 8 passes through the corresponding side of the adjustment frame 6 and is connected to a camera 9 for detecting the appearance of the memory chip. The second servo motor 8 can control the camera 9 to adjust its angle, thereby focusing on other areas of the memory chip. A rotating rod (not shown in the figure) is connected to the side of the camera 9 away from the second servo motor 8, and the rotating rod is movably inserted into the corresponding side of the adjustment frame 6 to ensure that the camera 9 remains stable when adjusting its angle.
[0024] Specifically, the bottom of the testing box 1 is fitted with a storage box 12 by multiple sets of bolts. The inner side of the storage box 12 is connected to multiple partitions by multiple sets of screws. The partitions divide the storage box 12 into multiple spaces, which facilitates the classified storage of storage chips.
[0025] Furthermore, a baffle 13 is hinged to one side of the outer wall of the storage box 12, and a handle 14 is connected to the side of the baffle 13 away from the storage box 12 by screws. The handle 14 facilitates opening or closing the baffle 13. A latch is installed between the baffle 13 and the corresponding side of the storage box 12 to fix the baffle 13. The baffle 13 can be opened by opening the latch.
[0026] Furthermore, a protective housing 11 is fitted on the outside of the first servo motor 2, and the protective housing 11 is connected to the corresponding side of the bottom of the detection box 1 by multiple screws to provide protection for the first servo motor 2 and prevent accidental contact when storing the memory chip.
[0027] It is worth noting that a silicone pad 10 is adhered to the top of the support disk 3, and the silicone pad 10 is flush with the edge of the support disk 3. This can increase the surface friction to stably support the memory chip and prevent the surface of the memory chip from being worn.
[0028] It is worth noting that a connecting frame 16 is hinged to one side of the outer wall of the test box 1, and an electromagnetic lock is installed on the corresponding side of the connecting frame 16 and the test box 1. The connecting frame 16 can be easily opened and closed by means of the electromagnetic lock.
[0029] It is worth mentioning that a transparent glass plate 17 (not shown in the illustration) is nested inside the connecting frame 16. The transparent glass plate 17 allows the view inside the detection box 1 to be seen when the connecting frame 16 is closed. Two supplementary lights 15 are symmetrically connected to the top inside the detection box 1, which can provide illumination when the light is insufficient, thus helping to improve the accuracy of the detection.
[0030] The first servo motor 2, the second servo motor 8, the camera 9, and the electromagnetic lock are existing technologies and will not be described in detail. Additionally, this utility model also includes a power supply, a controller, and switches, which are not the main technical points of this patent and will not be described in detail. The "front, back, left, and right" perspectives of this device are... Figure 1 The direction shown in the diagram is the reference.
[0031] Working principle: The memory chip is placed on top of the support plate 3. The camera 9 can focus on the surface of the memory chip for appearance inspection using existing principles. The support plate 3 can be rotated by the first servo motor 2 to control the rotation of the memory chip. The camera 9 can be rotated by a specified angle by the second servo motor 8 to drive the camera deflection. This changes the focus area of the camera 9 on the memory chip. If the camera is out of focus, the adjustment rod 4 can be turned to adjust the relative height of the camera 9 inside the adjustment frame 6, so that the camera 9 can refocus. The above structure ensures that the camera 9 can focus on any area of the memory chip, and the appearance inspection effect is more accurate.
