Description

Technical Field

[0001] The utility model relates to the field of detection equipment, in particular to a multi-point flatness detection device for a notebook computer shell. Background Art

[0002] The computer case flatness detection device is a device used to measure the flatness of the computer case surface. It is usually used for quality control of computer case production lines to ensure that the appearance and size of the product meet the design requirements. Flatness detection is crucial to ensuring the assembly accuracy of the case components, especially when the optical appearance and mechanical fit of the case are high. It detects the flatness of the computer case surface (usually detecting the surface deviation or warpage of the case) and provides accurate measurement data. It is suitable for computer cases of different sizes and shapes, including laptop cases, desktop cases, server cases, etc. The case surface is inspected and evaluated for flatness using sensors. The detection methods include optical, contact or non-contact measurement.

[0003] However, existing testing equipment often encounters the following problems: Traditional servo displacement detection requires precise movement of the servo system to sample each measurement point individually. This method is slow, especially when dealing with large numbers of products, and inefficient. Furthermore, the servo system requires precise mechanical movement to adjust the sensor position, which increases wear on mechanical components and leads to higher failure rates after long-term use. Utility Model Content

[0004] The main purpose of this utility model is to provide a multi-point flatness inspection device for laptop computer casings. This device effectively solves the problem mentioned in the background art of the existing conventional servo displacement inspection method, which requires each measurement point to be sampled individually through precise movement of the servo system. This method is slow in inspection speed and inefficient, especially when dealing with large quantities of products.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] In the description of the present invention, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "arranged," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0036] like Figure 1-4As shown, a multi-point flatness detection device for a laptop computer shell includes: a body 1, a base plate 2, a support rod 3, a tooling plate 4, a mounting frame 5, an infrared sensor 6, a limit groove 7, a positioning block 8, and a detection hole 9. The body 1 is erected on the ground and includes a power module, a computing module, and a control module, which are mainly used for calculation, storage, and uploading data. The base plate 2 is fixedly mounted on the top surface of the body 1, and at least four support rods 3 are distributed around the base plate 2. The bottom end of the support rod 3 is connected to the base plate 2, and the tooling plate 4 is mounted on the top of the support rod 3. The tooling plate 4 is a platform for placing the computer shell 10. The limit grooves 7 and detection holes 9 on its surface are to ensure the correct positioning of the computer shell 10 and the accurate detection of the sensor.

[0037] In this embodiment, the mounting bracket 5 is plugged into the base plate 2 through the positioning holes 15. The number of mounting brackets 5 and infrared sensors 6 corresponds to the number of detection holes 9. The mounting bracket 5 is designed to secure the infrared sensor 6. The infrared sensor 6 is connected to the top of the mounting bracket 5. A set of limit slots 7 is provided on the tooling plate 4. Positioning blocks 8 are slidably connected to the limit slots 7. A set of limit slots 7 is provided, distributed along the edges of the tooling plate 4. The combination of the limit slots 7 and positioning blocks 8 ensures that the computer housing 10 is fixed on the tooling plate 4, preventing displacement during the inspection process. A plurality of detection holes 9 are provided on the tooling plate 4, corresponding to the top positions of the infrared sensors 6. The computer housing 10 is placed on the tooling plate 4. A zero calibration plate 11 is located on one side of the computer housing 10 and is used before each batch of measurements to calibrate the infrared sensor 6 and ensure the accuracy of the inspection results. A control panel 12 is mounted on the body 1. The control panel 12 provides a user interface for controlling the detection process, displaying the detection results, and performing necessary settings and adjustments.

[0038] Preferably, a socket 13 is longitudinally defined at the top of the support rod 3, and a plugging protrusion 14 is provided on one side of the infrared sensor 6. This protrusion 14 is embedded in the socket 13, allowing vertical movement of the infrared sensor 6 to facilitate measurement at various locations on the computer housing 10. A plurality of positioning holes 15 are provided, distributed throughout the base plate 2, to which the bottom surface of the mounting bracket 5 is plugged. This design allows the infrared sensor 6 to be longitudinally moved, facilitating measurement at various locations on the computer housing 10, while also facilitating maintenance. For example, if any infrared sensor becomes damaged, it can be easily replaced by simply removing it.

[0039] It should be noted that the multi-point flatness inspection device for laptop computer cases designed in this utility model is designed to be used. Before measuring each batch of computer cases 10, a zero calibration plate 11 is placed on the tooling plate 4 and debris is wiped off. The infrared sensor 14 is then manually pushed to longitudinally displace its plug-in protrusion 14 on the plug-in port 13 to adjust its position and ensure the sensor is within its detection tolerance. At this point, the control panel 12 activates all infrared sensors via commands. The infrared sensor detection end passes through the detection hole 9 and reaches the zero calibration plate 11. The infrared sensor detects the reflection value of the zero calibration plate 11, which is the standard value minus zero. Upper and lower tolerances are set. The zero calibration plate 11 is then removed, completing the standard setup steps. After this, product testing begins. The computer cases 10 are placed on the tooling plate 4, and all positioning blocks 8 are pushed to slide within the limit slots 7 until they contact and secure the computer cases 10. Testing is complete, and the control panel 12 automatically displays the measurement results, indicating whether the product passes the test and the absolute value of the deviation at each measured point. All the measured points are detected at the same time, and dozens of points can be detected at the same time efficiently, quickly and accurately.

[0040] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the invention, and the scope of the invention is defined by the appended claims and their equivalents.
