Description

Technical Field

[0001] This utility model belongs to the field of optical inspection equipment technology, and specifically relates to a device for detecting microhole defects in a mid-frame. Background Technology

[0002] The fabrication of micro-holes in the mid-frame of smartphones is a crucial process in mobile phone manufacturing. These micro-holes serve functions such as weight reduction, heat dissipation, and mounting components (e.g., speakers, microphones). With the increasing thinness and high performance of smartphones, the size of these micro-holes is shrinking, leading to higher requirements for processing precision and quality. Manual inspection lines typically involve multiple inspection stages, each with varying degrees of difficulty in automating manual processes. Traditional vision inspection systems are often bulky; directly replacing a stage in the existing manual inspection process with a pre-developed traditional vision inspection device could affect the process layout density of the inspection line and potentially reduce production efficiency. The rapid pace of technological advancements in 3C digital products necessitates frequent adjustments to the inspection line. However, traditional vision inspection equipment is cumbersome, and the lens angle requires pre-adjustment, resulting in lengthy equipment handling and debugging processes during line adjustments, severely hindering efficiency improvements.

Figure 2As shown, the product moving assembly 1 includes a clamp 11, a first sliding assembly 12, and a first rotating assembly 13. A mounting groove 113 is formed by hollowing out the center of the clamp 11. A first pressing block 111 and a second pressing block 112 are respectively provided on two mutually perpendicular sides of the mounting groove 113. By placing the middle frame to be tested into the mounting groove 113 and adjusting the positions of the first pressing block 111 and the second pressing block 112, the middle frame to be tested is pressed and fixed onto the clamp 11.

The first motor 123 is located at one end of the first slide rail 121 and drives the lead screw on the first slide rail 121 to rotate via a coupling, thereby moving the first mounting bracket 122. A set of bearings is provided on the side of the first mounting bracket 122 near the clamp 11, and the bearings are rotatably connected to the rotating shaft 114 on the clamp 11. The first sliding assembly 12 enables precise horizontal movement of the clamp 11, ensuring alignment between the micro-aperture and the imaging area.

The second sliding component 26 includes a second slide rail 261 and a third motor 262, and the third sliding component 27 includes a third slide rail 271 and a fourth motor 272. The second slide rail 261 and the third slide rail 271 are arranged on the same straight line. The positions of the first refractive prism 21 and the second refractive prism 22 in the horizontal direction are adjusted by the third motor 262 and the fourth motor 272, respectively. The second sliding assembly 26 and the third sliding assembly 27 are symmetrically mounted on the second mounting bracket 28 and are detachably connected to the second mounting bracket 28. The third motor 262 and the fourth motor 272 are arranged opposite to each other. The third motor 262 is rotatably connected to the second slide rail 261 through a set of transmission wheels. The fourth motor 272 is rotatably connected to the third slide rail 271 through a set of transmission wheels. The third motor 262 is located below the second slide rail 261 and is connected through a transmission belt.

The second drive wheel 294 is rotatably connected to the second transmission wheel 292 via the second transmission belt 293. A reflecting prism 23 and a steering prism 24 are sequentially arranged on the rotating platform 291 from top to bottom. The reflecting prism 23, the first refractive prism 21, and the second refractive prism 22 are all located on the same horizontal plane. The multiple refraction and reflection design of the optical assembly helps reduce errors caused by changes in ambient light, angular shifts, or image blurring. A camera 25 is positioned near the steering prism 24 and rests on a counterweight 210, with the lens of the camera 25 facing the steering prism 24. The counterweight 210 and the second mounting bracket 28 are symmetrically arranged on both sides of the rotating platform 291. Balanced center of gravity reduces uneven stress on the rotating platform and optical components during rotation, thereby protecting these components from deformation or positional shifts and extending the equipment's lifespan.
