Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically to a device for measuring dimensions. Background Technology

[0002] As the precision requirements for smartphone structural components continue to increase, the dimensional accuracy of the phone's mid-frame, as a key component connecting the screen and the back cover, has a significant impact on the overall assembly performance.

[0003] Existing methods for measuring the sides of a mobile phone's mid-frame still have several limitations: The current fixed or limited-adjustment structures using single-laser, single-vision inspection components have limitations when inspecting features on both sides of the workpiece. Because the inspection angle is relatively fixed, it is difficult to simultaneously acquire complete feature information from both sides of the workpiece, often requiring multiple adjustments to the workpiece position or equipment parameters, resulting in a cumbersome inspection process and potentially impacting efficiency. Furthermore, due to the limited observation angle, there may be instances where local feature recognition is incomplete. For workpieces with complex, multi-feature characteristics, there is still room for further optimization in terms of both convenience and accuracy.

[0004] Therefore, there is an urgent need for a size measurement device to solve the above problems. Utility Model Content

[0005] Based on the above, the purpose of this utility model is to provide a size measurement device to solve the problem of workpiece size detection.

[0043] In one embodiment of this utility model, such as Figure 1-6 As shown, a size measurement device is provided, including: a detection area 1, a first line laser profile measuring instrument 2, a second line laser profile measuring instrument 3, a first vision inspection component 4, a second vision inspection component 5, and a mounting base 6. The first line laser profile measuring instrument 2 is disposed at the top of the detection area 1 and moves repeatedly along the X, Y, and Z axes of the detection area 1. The beam of the first line laser profile measuring instrument 2 illuminates the plane of the detection area 1 at an inclined angle. The second line laser profile measuring instrument 3 is disposed to the side of the first line laser profile measuring instrument 2 and moves repeatedly along the Y and Z axes of the detection area 1 together with the first line laser profile measuring instrument 2, and moves along the X axis in the direction of the first line laser profile measuring instrument 2. The illumination direction of the second line laser profile measuring instrument 3 is opposite to or opposite to the illumination direction of the first line laser profile measuring instrument 2. The first visual detection component 4 is positioned to the side of the first linear laser profile measuring instrument 2. It moves repeatedly along the Y-axis of the detection area 1 along with the instrument. The first visual detection component 4 can also move along the X and Z axes of the detection area 1. It takes images in a direction parallel to the detection area 1. The second visual detection component 5 is positioned to the side of the first visual detection component 4. It moves repeatedly along the Y and Z axes along with the first visual detection component 4, and also moves along the X-axis in the direction of the first visual detection component 4. The image-taking direction of the second visual detection component 5 is opposite to that of the first visual detection component 4. The mounting base 6 is located within the detection area 1 and at the bottom of the first linear laser profile measuring instrument 2. It moves repeatedly along the Y and Z axes of the detection area 1. Mounting base 6 carries the workpiece. While moving along the Y and Z axes of the detection area 1, the first line laser profile measuring instrument 2 repeatedly moves along the X, Y, and Z axes. The second line laser profile measuring instrument 3 moves repeatedly along the Y and Z axes with the first line laser profile measuring instrument 2. The first vision detection component 4 moves along the Y axis with the first line laser profile measuring instrument 2, and can also move along the X and Z axes of the detection area 1. The first line laser profile measuring instrument 2 detects the three-dimensional features on one side of the workpiece. The second line laser profile measuring instrument 3 moves along the X axis, either away from or closer to the first line laser profile measuring instrument 2, and detects the three-dimensional features on the other side of the workpiece. The first vision detection component 4 detects the planar features on one side of the workpiece. The second vision detection component 5 moves along the X axis, either away from or closer to the first vision detection component 4, and detects the planar features on the other side of the workpiece.

[0044] The dimensional measurement device provided by this utility model, through the linkage structure of dual lasers (the first line laser profile measuring instrument 2 can move along the X, Y, and Z axes, and the second line laser profile measuring instrument 3 moves along the Y and Z axes and can be independently adjusted along the X axis) and dual vision detection components (the first vision detection component 4 moves along the Y axis with the laser and can be independently adjusted along the X and Z axes, and the second vision detection component 5 moves along the Y and Z axes and can be independently adjusted along the X axis), not only simultaneously completes the accurate detection of the three-dimensional and planar features on both sides of the workpiece, effectively simplifying the measurement process, but also forms a 360-degree view that surrounds the workpiece, enabling full-size detection of the workpiece and greatly improving detection efficiency, especially meeting the batch detection needs of complex multi-feature workpieces; at the same time, the corresponding detection mode of the dual lasers and dual vision detection components avoids the measurement blind spots of a single view, and the positioning stability brought by the linkage of components effectively reduces measurement errors, ensures the accuracy and consistency of dimensional data, and improves the practicality and applicability of the device.

[0045] In this embodiment, the first visual inspection component 4 and the second visual inspection component 5 can be combined from a camera, lens and light source. They can replace manual labor to complete the inspection of barcode characters, cracks, packaging, whether the surface layer is complete, dents, etc. Using a visual inspection system can effectively improve the inspection speed and accuracy of the production line, greatly increase output and quality, reduce labor costs, and prevent misjudgments caused by human eye fatigue.

[0046] In this embodiment, the system can be used to detect the full feature dimensions of the mid-frame of a mobile phone and a tablet. The first line laser profile measuring instrument 2 and the second line laser profile measuring instrument 3 are used to detect the dimensions of three-dimensional features, specifically the hole depth and step difference. The first vision detection component 4 and the second vision detection component 5 are used to detect the dimensions of planar features, specifically the length and width of the side hole and the distance between the side hole and the end face.

[0047] In this embodiment, a visual inspection component can be installed on one side of the first-line laser profile measuring instrument 2, so that stable reference coordinates can be obtained synchronously during laser inspection, eliminating the measurement deviation caused by the reference offset during laser movement, thereby ensuring that the coordinate system of three-dimensional feature detection and planar feature detection is the same, and improving the correlation and consistency of measurement data in different dimensions.

[0048] In this embodiment, as Figure 4 As shown, it also includes a first driving component 8, which is connected to the first line laser profile measuring instrument 2 and the first vision detection component 4. The first driving component 8 is used to drive the first line laser profile measuring instrument 2 to move repeatedly along the Y-axis along the detection area 1.

[0049] Specifically, the first drive assembly 8 includes a frame 801 and a first Y-axis drive source 802. The frame 801 is mounted on the top of the detection area 1, the first Y-axis drive source 802 is mounted on the top of the detection area 1, the frame 801 is mounted on the output end of the first Y-axis drive source 802, and the first line laser profile measuring instrument 2 and the first vision detection assembly 4 are both mounted on the frame 801.

[0050] This synchronizes the Y-axis movement of the laser and the vision inspection component, ensuring they maintain a fixed relative position and guaranteeing the coordinate consistency of stereo feature detection and planar feature detection in the Y-axis direction. This significantly reduces the difficulty of data stitching and calibration, improves measurement accuracy, and enhances overall inspection efficiency and reliability.

[0051] Furthermore, the device for measuring this size, such as Figure 3 As shown, it also includes a second drive component 9, which is installed between the frame 801 and the first linear laser profile measuring instrument 2, and between the frame 801 and the first vision detection component 4, respectively, to drive the first linear laser profile measuring instrument 2 and the first vision detection component 4 to move along the X and Z axes, respectively.

[0052] Specifically, the second drive assembly 9 includes a first X-axis drive source 901, a second X-axis drive source 902, a first Z-axis drive source 903, and a second Z-axis drive source 904. The first X-axis drive source 901 and the second X-axis drive source 902 are respectively mounted on both sides of the frame 801. The first Z-axis drive source 903 and the second Z-axis drive source 904 are respectively mounted on the output ends of the first X-axis drive source 901 and the second X-axis drive source 902. The first line laser profile measuring instrument 2 is mounted on the output end of the first Z-axis drive source 903. The first vision inspection assembly 4 is mounted on the output end of the second Z-axis drive source 904.

[0053] This allows the first-line laser profile measuring instrument 2 and the first vision inspection component 4 to have completely independent adjustment space in the X and Z axes. They can accurately adjust their respective inspection postures according to the actual position of the workpiece's three-dimensional and planar features, effectively eliminating mutual interference caused by linkage adjustment and avoiding blind spots in inspection. At the same time, independent drive greatly improves the equipment's adaptability to workpieces of different sizes and complex shapes, and can complete diverse inspection tasks without changing the inspection components. In addition, the clear division of labor among the drive sources reduces the load on a single drive source, extends the service life of the equipment, and further improves the stability and accuracy of inspection.

[0054] Furthermore, such as Figure 6As shown, the size measurement device also includes a third drive assembly 10, which is installed between the output end of the first Z-axis drive source 903 and the second linear laser profile measuring instrument 3, and between the output end of the second Z-axis drive source 904 and the second vision inspection assembly 5.

[0055] The third drive assembly 10 includes a third X-axis drive source 101 and a fourth X-axis drive source 102. The third X-axis drive source 101 is installed at the output end of the first Z-axis drive source 903. The second line laser profile measuring instrument 3 is installed at the output end of the third X-axis drive source 101. The fourth X-axis drive source 102 is installed at the output end of the second Z-axis drive source 904. The second vision detection assembly 5 is installed at the output end of the fourth X-axis drive source 102.

[0056] This allows the second-line laser profile measuring instrument 3 and the second vision inspection component 5 to be flexibly adjusted according to the actual X-axis position of the features on the other side of the workpiece, without being limited by the position of the first-line laser profile measuring instrument 2 and the first vision inspection component 4. This adapts to the inspection needs of features on both sides of asymmetrical and irregularly shaped workpieces, avoiding the tedious process of repeatedly adjusting the workpiece. At the same time, independent adjustment ensures that the second-line laser profile measuring instrument 3 and the second vision inspection component 5 are always in the optimal inspection position, improving the accuracy of feature inspection on both sides of the workpiece and making it easier to match the data on both sides. In addition, the drive source specifically drives a single component, resulting in a smaller load, more stable operation, further extending the service life of the equipment and broadening the applicable scenarios of the equipment.

[0057] Preferred, such as Figure 5 As shown, the size measuring device also includes a fourth drive assembly 11, which is located at the bottom of the detection area 1. The fourth drive assembly 11 is connected to the mounting base 6 and is used to drive the mounting base 6 to move repeatedly along the Y and Z axes.

[0058] Specifically, the fourth drive assembly 11 includes a second Y-axis drive source 111 and a third Z-axis drive source 112. The third Z-axis drive source 112 is installed at the output end of the second Y-axis drive source 111, and the mounting base 6 is installed at the output end of the third Z-axis drive source 112.

[0059] The fourth drive component 11 enables the Y and Z axis linkage motion of the mounting base 6, allowing the workpiece to actively adapt to the detection position of the laser and vision inspection components. This significantly reduces the adjustment frequency of the inspection components, effectively reducing errors caused by frequent adjustments and improving measurement accuracy. Simultaneously, the active movement of the workpiece expands the inspection coverage, effectively eliminating blind spots in the inspection of complex and large workpieces and enhancing the equipment's adaptability to diverse workpieces. Furthermore, the stable operation of the dual-axis drive structure ensures precise workpiece positioning, further guaranteeing the reliability and efficiency of the inspection.

[0060] Preferred, such as Figure 5 As shown, a rotary drive source 12 is mounted on the output end of the third Z-axis drive source 112, and a mounting base 6 is mounted on the output end of the rotary drive source 12. This allows the workpiece to obtain rotational freedom, enabling it to be adapted to specific feature detection without manual adjustment, significantly shortening the detection preparation time. At the same time, the rotational motion enables continuous scanning of workpiece features, avoiding data splicing errors from segmented detection and improving measurement integrity and accuracy.

[0061] The X, Y, and Z axis drive sources can be motors and screws. When each component moves along the axis, the displacement is precise and the start and stop are stable, without obvious shaking or deviation, thus ensuring the positioning accuracy of the laser detection and vision inspection components.

[0062] In this embodiment, an auxiliary slide rail 14 (the slider and the slide rail slide together, and the load-bearing component is rigidly connected to the slider) can be added next to each axis drive source (motor + screw rod) to restrict the component to a fixed trajectory when it moves along the axis, so as to avoid the swing or deviation caused by the screw rod being subjected to force on one side, thereby ensuring the linearity and stability of the movement.

[0063] In this embodiment, as Figure 4 As shown, by configuring a light source adapted to the vision inspection component (such as a coaxial light source or a ring light source, which maintains a fixed relative position with the vision inspection component), the surface features of the workpiece can be illuminated uniformly when the vision inspection component takes pictures, avoiding image blurring caused by reflections or shadows, thereby improving the imaging clarity of planar features and ensuring the edge recognition accuracy of dimensional measurements.

[0064] In this embodiment, a workbench 16 providing a stable mounting reference can be installed in the load-bearing detection area 1 and at each component, and a protective cover 17 surrounds the workbench 16, such as... Figure 1 As shown, this ensures a stable and controllable operating environment for the equipment, guarantees the installation accuracy of each drive component and detection part, thereby reducing the interference of external factors on laser detection and image acquisition, and improving the stability of measurement data.

[0065] The steps for detecting 3D and planar features in this embodiment are as follows: The workpiece is fixed to the mounting base 6. The fourth drive component 11 drives the mounting base 6 to move along the Y and Z axes. The rotation drive source 12 adjusts the workpiece angle. The positioning reference point vision detection component 7 synchronously captures the reference mark on the mounting base 6 to establish a global coordinate system. The first drive component 8 drives the frame 801 to move along the Y axis. The first line laser profile measuring instrument 2 moves synchronously with the frame 801. Simultaneously, the second drive component 9 drives it to fine-tune along the X and Z axes to scan the 3D features (such as protrusions and grooves) on one side of the workpiece at an inclined angle. The third drive component 10 drives the second line laser profile measuring instrument 3 to move closer to / away from the first line laser profile measuring instrument 2 along the X axis. The frame 801 synchronously completes the Y and Z axis movement, performing a symmetrical scan of the 3D features on the other side of the workpiece. The dual laser data is linked to the global coordinate system in real time. The first vision detection component 4 moves along the Y axis with the frame 801. The second drive component 9 independently adjusts its X and Z axis position to photograph the planar features (such as apertures and contours) on one side of the workpiece in parallel. The adapter light source 15 provides synchronous supplementary lighting. The fourth X-axis drive source 102 drives the second vision inspection component 5 to adjust along the X-axis, and together with the first vision inspection component 4, completes the Y and Z axis linkage, symmetrically capturing the planar features on the other side of the workpiece. The image edge information is calibrated based on global coordinates. The system integrates the stereo data from the dual lasers with the planar data from the dual vision inspection components, completes the dimension calculation based on a unified coordinate reference, and generates an inspection report. After the inspection is completed, the workpiece is removed.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
