[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 phone's mid-frame have several problems: they generally use prism reflection, which results in low measurement accuracy and is greatly affected by ambient light, leading to low detection precision; setting up a measuring tool on one side and then using a clamp to rotate multiple times for multi-angle measurements is not only cumbersome and inefficient, but also allows for the measurement of only one surface at a time. Furthermore, it is prone to introducing errors during clamping and rotation, making it impossible to ensure the absolute levelness and consistent positioning of the phone's mid-frame.

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

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0042] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Furthermore, the terms "first" and "second" are used merely for descriptive distinction and have no specific meaning.

[0043] In one embodiment of this utility model, such as Figure 1-5As shown, a side measurement device for a mobile phone frame is provided, including: a detection component 1 and a fixture 2. The detection component 1 comprises at least two symmetrically arranged groups, each group including a laser projection module 101 and an image acquisition module 102; a detection area is formed between the opposing detection component 1 blocks; the laser projection module 101 is used to measure the three-dimensional dimensions of the side of the mobile phone frame; the image acquisition module 102 is used to measure the planar dimensions of the side of the mobile phone frame.

[0044] Fixture 2 is set in the detection area and is used to load the mobile phone frame.

[0045] The side measurement device for mobile phone mid-frame provided in this utility model achieves non-contact high-precision measurement through symmetrically arranged laser projection module 101 and image acquisition module 102, effectively avoiding measurement errors caused by traditional prism reflection methods. The laser-image combined measurement method has good environmental adaptability, reduces external light interference, and improves measurement stability. Through at least two sets of oppositely arranged detection components 1, at least two opposite sides of the mobile phone mid-frame can be measured simultaneously, avoiding errors introduced by multiple clamping or rotation.

[0046] Preferably, the projection direction of the laser projection module 101 intersects with the clamping and positioning direction of the fixture 2. The laser projection module 101 is used to measure the three-dimensional dimensions of the side of the mobile phone frame, specifically the hole depth and step difference. The acquisition direction of the image acquisition module 102 is perpendicular to the clamping and positioning direction of the fixture 2. The image acquisition module 102 is used to measure the planar dimensions of the side of the mobile phone frame, specifically the length and width of the side hole and the distance between the side hole and the end face.

[0047] Specifically, the laser projection module 101 consists of a line laser 111, and the image acquisition module 102 consists of a camera 121 and a lens 122. The line laser 111 and the camera 121 are arranged side by side and move synchronously. The lens 122 is mounted on the imaging end of the camera 121. The line laser 111, camera 121, and lens 122 all measure along the outer side of the clamping part of the mobile phone frame of the fixture 2. This achieves simultaneous measurement of the three-dimensional and planar dimensions of the features on the side of the mobile phone frame.

[0048] The side measurement device for the mid-frame of a mobile phone also includes a worktable 3, the surface of which is used to place the detection component 1 and the fixture 2. Additionally, a protective cover 4 can be installed on the worktable 3 to protect and cover the detection area, isolate it from external light interference, and prevent dust from entering the measurement space.

[0049] In this embodiment, a data processing module is also included. The data processing module is electrically connected to the laser projection module 101 and the image acquisition module 102 respectively. The data processing module is used to receive the three-dimensional coordinates of the laser projection module 101 and the image information acquired by the image acquisition module 102, and process them to obtain measurement data of the side features of the mobile phone frame.

[0050] In this embodiment, the laser projection module 101 is composed of a line laser 111, and the image acquisition module 102 is composed of a camera 121 and a lens 122. The line laser 111 and the camera 121 are arranged side by side and move synchronously, and the lens 122 is mounted on the imaging end of the camera 121. The line laser 111, the camera 121, and the lens 122 all perform linear scanning along the outer side of the clamping frame of the mobile phone in the fixture 2.

[0051] Among them, the line laser 111 scans synchronously with the camera 121, and can be combined with the autofocus technology of the lens 122 to effectively identify the side features to be measured on the middle frame of the mobile phone.

[0052] Preferably, each set of detection components 1 can move towards or away from each other to adjust the relative distance between the two sets of detection components 1, so as to adapt to the variable distance detection requirements of mobile phone frames with different length and width dimensions.

[0053] In this embodiment, the detection component 1 is mounted on the worktable 3 via the slide 14, wherein at least one set of detection components 1 is mounted on the output end of the slide 14, and another set of detection components 1 is fixed on the worktable 3 or separately mounted on another slide 14. By activating the slide 14, the spacing between the detection components 1 can be adjusted.

[0054] The side measurement device for the mobile phone frame also includes a drive component 5 mounted on the worktable 3. The drive component 5 is used to drive the detection component 1 to move the detection area to fully scan the mobile phone frame.

[0055] Specifically, the drive assembly 5 includes a first drive source 501 (such as a slide table 14), a second drive source 502 (such as a slide table 14), and a third drive source 503 (such as a cylinder), which are used to control the precise movement of the detection assembly 1 in the longitudinal, lateral, and vertical directions, respectively. The first drive source 501 drives the overall structure to move along the horizontal longitudinal direction, realizing the adjustment of the front and rear position of the detection assembly 1; the second drive source 502 is installed at the output end of the first drive source 501, driving the detection assembly 1 to move along the horizontal lateral direction to adapt to the mid-frame structure with different widths; the third drive source 503 controls the lifting and lowering action of the detection assembly 1 in the vertical direction, which facilitates avoiding the mid-frame of the mobile phone or adjusting the measurement height. Through three-degree-of-freedom linkage control, multi-dimensional and high-precision position adjustment of the detection assembly 1 is realized, improving the compatibility and measurement flexibility of the device for different types of mobile phone mid-frames, while providing reliable motion platform support for automated detection.

[0056] The side measurement device for the mobile phone frame also includes an auxiliary guide rail 6 mounted on the worktable 3. The auxiliary guide rail 6 has a first guide rail 601, a second guide rail 602, and a third guide rail 603 respectively at the output ends of the first drive source 501, the second drive source 502, and the third drive source 503. Through the arrangement of these guide rails, the displacement of each drive source in its corresponding motion direction can be effectively guided and stabilized, improving the smoothness and guiding accuracy during movement. Simultaneously, the auxiliary guide rail 6 can effectively reduce the frictional resistance between sliding components, reduce motion errors, and enhance the overall stability and repeatability of the device, thereby further ensuring the accuracy and reliability of the detection component 1 in multi-degree-of-freedom movement and improving the consistency and credibility of the measurement results.

[0057] Preferably, at least two clamps 2 are provided to form a dual-station structure, and the surface of the worktable 3 is provided with double openings 13, with the two clamps 2 respectively disposed in the double openings 13.

[0058] In practical use, the clamp 2 can quickly clamp and accurately position the mobile phone frame through pin positioning, magnetic suction cup or other adaptable structures to ensure that it maintains a stable posture during the measurement process. Among them, pin positioning is suitable for frame structures with standard holes, while magnetic suction cup is suitable for metal frames. It can achieve non-marking clamping, convenient operation, and effectively improve loading and unloading efficiency and measurement repeatability accuracy.

[0059] Preferably, at least two fixtures 2 are provided to form a dual-station structure, and the surface of the worktable 3 is provided with two openings 13, with the two fixtures 2 respectively embedded in the corresponding openings 13. By setting up a dual-station structure, multiple mobile phone frames can be inspected simultaneously on the same equipment, effectively improving measurement efficiency; at the same time, the alternating operation of the dual stations can also realize the parallel operation of loading and unloading and inspection processes, further improving the automation level and capacity utilization of the equipment. In addition, the cooperative layout of the fixtures 2 and the openings 13 of the worktable 3 helps to optimize the spatial structure, making the workpiece to be measured closer to the inspection component 1, improving measurement accuracy and stability.

[0060] To accommodate the dual-station fixture 2, the second drive source 502 moves the detection component 1 horizontally, precisely aligning it with different positions on the fixture 2. Simultaneously, the third drive source 503 controls the vertical lifting and lowering of the detection component 1 to adapt to and avoid different fixture 2 positions. This structure allows the detection component 1 to flexibly switch between multiple stations, ensuring high-precision measurement of the mobile phone frame at each station, further improving the automation level and detection efficiency of the equipment.

[0061] The side measurement device for the mobile phone frame also includes a first power source 10 (such as a slide table 14). The output end of the first power source 10 moves forward or backward in the horizontal direction. The output end of the first power source 10 is equipped with a second power source 11 (such as the slide table 14), and the output end of the second power source 11 moves up or down in the vertical direction. A fixture 2 is installed at the output end of the second power source 11. The fixture 2 is used to support and position the mobile phone frame to be measured. The fixture 2 can achieve two-dimensional precise movement in both the horizontal and vertical directions, thereby flexibly adjusting the relative position between the frame to be measured and the detection component 1 to adapt to the measurement needs of products of different sizes.

[0062] Preferably, the clamp 2 is connected to the second power source 11 via a rotation source 12 (such as a cylinder). The rotation source 12 is installed at the output end of the second power source 11, and the clamp 2 is fixed to the output end of the rotation source 12, so as to realize the vertical lifting and rotational movement of the clamp 2 around the axis. This structure allows the clamp 2 to drive the mobile phone frame to make multi-angle adjustments during the measurement process, which facilitates the continuous scanning of the long and short sides of the frame by the detection component 1, and improves the measurement adaptability and completeness.

[0063] The process of measuring the two long sides of the mobile phone frame of this utility model is as follows: First, the mobile phone frame to be tested is placed on the fixture 2. Then, the drive component 5 is started, which drives the line laser 111, camera 121 and lens 122 to move along the set path. At the same time, the fixture 2 moves along the detection area. When the fixture 2 moves to the detection area, the lens 122 starts to locate the reference point and simultaneously detects the planar dimensional features (such as the whole length, the length and width of the side hole and the distance of the side hole from the end face) on the two long sides of the mobile phone frame. At the same time, the line laser 111 measures the three-dimensional dimensional features (such as the hole depth and the step difference) on the side of the long side of the mobile phone frame.

[0064] The process of measuring the width of both sides of the mobile phone frame in this utility model is as follows: the clamp 2 drives the mobile phone frame to rotate through the rotation source 12, so that the width of the mobile phone frame faces the lens 122.

[0065] The drive slide 14 adjusts the distance between the two sets of detection components 1 to accommodate changes in the orientation of the phone's mid-frame on the fixture 2, ensuring that the detection components 1 and the mid-frame of the phone under test maintain the optimal measurement position. Then, the dimensional features of the wide sides of the phone's mid-frame are detected by the line laser 111, camera 121, and lens 122.

[0066] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. 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. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
