Description

Technical Field

[0001] This utility model relates to the field of automated testing, and in particular to a high-precision laptop casing testing device. Background Technology

[0002] Laptop casing inspection equipment is a specialized automated system designed to inspect the quality of laptop casings. These devices typically integrate high-resolution cameras, laser scanners, precision mechanics, and advanced image processing software to automatically detect key parameters such as dimensional accuracy, surface quality, warpage, and flatness. The purpose of this inspection equipment is to ensure that laptop casings meet design specifications during the manufacturing process, thereby guaranteeing the overall quality and performance of the product.

[0003] Laptop casing inspection equipment is primarily used in the 3C electronics manufacturing industry, especially on laptop production lines. This equipment can automatically detect appearance defects, dimensional accuracy, and surface quality of the casing, ensuring that products meet quality standards. Furthermore, this inspection equipment can also be applied to other industries requiring precision inspection, such as automotive manufacturing, semiconductors and integrated circuits, photovoltaics, home appliance manufacturing, and precision machinery and instruments.

[0004] However, existing laptop casing inspection equipment has the following problems when in use:

[0005] (1) Existing casing inspection equipment often lacks precision when inspecting small gaps, especially for gaps at the corners of computer casings, which are difficult to inspect accurately due to insufficient light.

[0006] (2) Most existing casing inspection equipment is designed to adjust the position of the X, Y, and Z axes of the inspection lens so that the lens can be inspected around the computer casing. This design will concentrate most of the turning and transmission parts near the lens, which not only makes it difficult to ensure the stability of the lens during displacement, but also makes it difficult to maintain. Utility Model Content

[0007] The main objective of this invention is to provide a high-precision laptop casing inspection device, which can effectively solve the problem mentioned in the background art that existing casing inspection devices often lack precision when inspecting relatively small gaps.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A high-precision laptop casing inspection device, comprising:

[0010] Work platform;

[0011] The mounting platform is disposed on the top surface of the working platform;

[0012] The first lead screw slide is longitudinally mounted on the top surface of the mounting platform;

[0013] The second lead screw slide is mounted horizontally on the slider of the first lead screw slide.

[0014] The folding hose is provided in two sets, and the two sets of folding hoses are installed side by side on the mounting platform. The two sets of folding hoses are connected to both ends of the second lead screw slide.

[0015] An operating table, which is mounted on the slider of the second lead screw slide;

[0016] A chain plate, which is connected to the bottom surface of the operating table;

[0017] A support frame is installed in the extending direction of one end of the first lead screw slide;

[0018] A fixing plate, which is longitudinally mounted on the support frame;

[0019] A lifting cylinder, one side of which is mounted on the fixed plate;

[0020] An edge-grabbing combination lens is installed at the output end of the lifting cylinder.

[0021] The edge-grabbing combination lens also includes:

[0022] A debugging board is installed on one side of the output end of the lifting cylinder;

[0023] A baffle, one side of which is connected to the debugging board;

[0024] Slots, at least two of which are respectively provided on the debugging board and the baffle;

[0025] A high-resolution camera, which is snapped into a slot on the debugging board;

[0026] A telephoto lens, which is mounted on the lens of the high-resolution camera;

[0027] A scanning image camera, which is snapped into a slot in the baffle;

[0028] A supplementary light is located below the scanning image camera and is electrically connected to the scanning image camera;

[0030] Also includes:

[0031] A control platform is installed on one side of the working platform, and the high-pixel camera is electrically connected to the control platform.

[0037] Compared with the prior art, the beneficial effects of this utility model are:

[0038] (1) This utility model, through the combination of a high-pixel camera and a telephoto lens, can perform high-precision dimensional scanning of the laptop casing, especially for the detection of small gaps, thus improving the accuracy and reliability of the detection. Through the unique edge-gripping lens design and the non-coplanar layout of the high-pixel camera and the scanning image camera, the detection angle and range are expanded, making it more efficient, especially when detecting complex parts such as the corners of laptops.

[0039] (2) This utility model adjusts the displacement of the operating table by linking the first lead screw slide and the second lead screw slide, and distributes the displacement mechanism evenly. With the buffering of the folded hose and chain plate, it further ensures the smooth movement of the operating table during the detection process, reduces mechanical vibration, and improves the stability of the detection.

[0044] 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.

[0045] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0046] like Figure 1-2As shown, a high-precision laptop casing inspection device includes a work platform 1, a mounting platform 2, a first lead screw slide 3, a second lead screw slide 4, a folded flexible tube 5, an operating table 6, a chain plate 7, a support frame 8, a fixing plate 9, a lifting cylinder 10, and a gripping lens assembly 11. The mounting platform 2 is positioned on the top surface of the work platform 1. The first lead screw slide 3 is longitudinally mounted on the top surface of the mounting platform 2. The bottom surface of the second lead screw slide 4 is horizontally mounted on the slider of the first lead screw slide 3. Two sets of folded flexible tubes 5 are provided, and the two sets of folded flexible tubes 5 are installed side-by-side on the mounting platform 2. The two sets of folded flexible tubes 5 are connected to both ends of the second lead screw slide 4. The first lead screw slide 3 is located between the two folded flexible tubes 5. The design of the folded flexible tubes 5 provides a flexible connection, allowing the operating table 6 to move smoothly during the inspection process, while providing necessary cushioning for the equipment and reducing mechanical impact. The operating table 6 is mounted on the slider of the second lead screw slide 4. The chain plate 7 is connected to the bottom surface of the operating table 6. The operating table 6 is where the laptop casing is placed. The chain plate 7 is connected to the operating table 6, and its sliding motion ensures the stability of the operating table 6 during lateral displacement, which is crucial for accurate dimensional measurement. The support frame 8 is mounted in the extension direction of one end of the first lead screw slide 3. The fixing plate 9 is mounted longitudinally on the support frame 8. One side of the lifting cylinder 10 is mounted on the fixing plate 9, and the edge-gripping combined lens 11 is mounted on the output end of the lifting cylinder 10.

[0047] Preferably, as described above, dragging the chain plate 7 to slide the operating table 6 makes the movement of the operating table 6 more stable because the chain plate 7 has good load-bearing capacity and stable transmission characteristics. Due to the continuously movable joint design of the chain plate 7 itself, it can provide continuous and uniform power transmission, thereby ensuring the smooth movement of the operating table 6 during the inspection process. This is particularly important for precision inspection equipment, as smooth movement can reduce potential damage to the object being inspected and improve the accuracy and repeatability of the inspection data.

[0048] In this embodiment, the debugging board 111 is installed on one side of the output end of the lifting cylinder 10, and one side of the baffle 112 is connected to the debugging board 111. At least two slots 113 are respectively opened on the debugging board 111 and the baffle 112. The high-pixel camera 114 is snapped into the slot 113 of the debugging board 111, the telephoto lens 115 is installed at the lens of the high-pixel camera 114, and the scanning image camera 116 is snapped into the slot 113 of the baffle 112. The positions of the debugging board 111 and the baffle 112 are perpendicular, which means that the high-pixel camera 114 and the scanning image camera 116 are not on the same plane. This can expand the detection range of the overall edge-grabbing combination lens 11 and improve the detection efficiency, especially for the detection effect at the corner of the laptop. A supplementary light 117 is located below the scanning image camera 116 and is electrically connected to the scanning image camera 116. The design of the supplementary light 117 ensures that clear inspection images can be obtained under different lighting conditions. Especially when inspecting details such as the corners of laptops, the supplementary light 117 can reduce shadows and improve inspection quality. A displacement sensor 118 is mounted on the bottom of the debugging board 111. A control platform 12 is mounted on one side of the work platform 1, and a high-resolution camera 114 is electrically connected to the control platform 12.

[0049] This invention discloses a high-precision laptop casing inspection device. In use, the casing is placed on the operating table 6, and commands are transmitted via the control platform 12 to a high-pixel camera 114 for dimensional scanning. A telephoto lens 115 assists in detecting small gaps, improving accuracy. The first lead screw slide 3 is activated for width detection. The sliding of the slider of the first lead screw slide 3 causes the top second lead screw slide 4 to move axially relative to the operating table 6. During the sliding process, the second lead screw slide 4 pulls the folded flexible tubes 5 at both ends. The folded flexible tubes 5 are made of plastic, and when the second lead screw slide 4 slides, the folded flexible tubes 5 in the sliding direction are compressed to provide cushioning for the second lead screw slide 4. Next, the second lead screw slide 4 is activated for length detection. The sliding of the slider of the second lead screw slide 4 causes the operating platform 6 on its top to begin lateral displacement. The lateral displacement of the operating platform 6 drags the chain plate 7 on the bottom surface to slide, making the lateral displacement of the operating platform 6 more stable. After adjusting to the appropriate position, the lifting cylinder 10 is activated. The output end of the lifting cylinder 10 presses down, causing the adjustment plate 111 to move down. The displacement sensor 118 will detect the displacement segment in real time and feed it back to the control platform 12. During this detection process, the scanning image camera 116 can be activated simultaneously to detect the flatness of the corners and bends of the outer shell. If the shadow is strong, the scanning image camera 116 will activate the supplementary light 117 according to the environment to enable the camera to clearly capture the information of the measured object.

[0050] It is worth noting that the lead screw slide involved in this utility model is a commonly used technical means in this field, and the process technology is mature. Therefore, its specific structural features will not be explained.

[0051] Embodiments of the present invention have been shown and described. It will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
