Two sets of synchronously operating lifting hydraulic cylinders 30 are symmetrically arranged at both ends of the optical inspection stage 10. Several sets of uniformly spaced, fixed frames 40 for placing laptop casings are mounted on the top surface of the optical inspection stage 10. A linked bottom-surface high-precision area array camera group 11 and a top-surface high-precision area array camera group 21 are respectively embedded on the top surface of the optical inspection stage 10 and the bottom surface of the adjustable top mount 20. Several sets of matrix-arranged CCD inspection cameras 12 are mounted on the top surface of the bottom-surface high-precision area array camera group 11 and the bottom surface of the top-surface high-precision area array camera group 21. A limiting groove 41 is formed on the edge of the top surface of the fixed frame 40, and fixed posts 42 are installed at the four corners of the bottom surface of the fixed frame 40. Through the multi-station optical inspection stage 10 and the adjustable top mount 20, and in conjunction with the two sets of synchronously operating lifting hydraulic cylinders 30 symmetrically arranged at both ends of the optical inspection stage 10, adjustable... The height of the top mount 20 can be flexibly adjusted to meet different inspection needs; several sets of evenly spaced fixed frames 40 mounted on the top surface of the optical inspection stage 10 provide a stable placement position for the laptop casing; the bottom high-precision area array camera group 11 embedded on the top surface of the optical inspection stage 10 and the top high-precision area array camera group 21 embedded on the bottom surface of the adjustable top mount 20, as well as several sets of matrix-arranged CCD inspection cameras 12 mounted on the top surface of the bottom high-precision area array camera group 11 and the bottom surface of the top high-precision area array camera group 21, can perform multi-angle, high-precision optical inspection of the laptop casing; the limiting groove 41 opened on the edge of the top surface of the fixed frame 40 facilitates the limiting and fixing of the laptop casing, preventing its movement from affecting the inspection results; the fixing posts 42 installed at the four corners of the bottom surface of the fixed frame 40 help the fixed frame 40 to be stably installed on the optical inspection stage 10. The overall structure works together to improve the efficiency and accuracy of optical inspection of defects in the laptop casing.

[0018] Furthermore, the top surface of the optical inspection worktable 10 is provided with several sets of fixing slots 13. The bottom surface of each set of fixing posts 42 is coaxially connected with a plug 43 that is compatible with the size of the fixing slot 13 and is plugged in, so that the fixing frame 40 can be stably installed on the optical inspection worktable 10, providing a stable foundation for the placement of the notebook casing.

[0019] It is worth noting that the interference fit between the connector 43 and the fixed slot 13 effectively prevents the fixed frame 40 from shaking or shifting during the testing process, thus ensuring the accuracy and reliability of the testing.

[0022] In addition, the piston rods of the two sets of lifting hydraulic cylinders 30 are respectively connected to the bottom ends of the adjustable top seat 20. Through the synchronous operation of the lifting hydraulic cylinders 30, the height of the adjustable top seat 20 can be adjusted stably and evenly to meet the requirements of the distance between the camera group and the laptop shell in different detection scenarios.

[0023] Working principle of this multi-station linkage optical inspection equipment for laptop casing defects: First, place the laptop shells to be inspected into the fixed frames 40 on the optical inspection worktable 10 in sequence. Use the limiting grooves 41 on the top edge of the fixed frame 40 to limit and fix the laptop shells to ensure that they will not move during the inspection process. Next, according to the testing requirements, the lifting hydraulic cylinders 30 that work synchronously at both ends of the optical inspection worktable 10 are activated to adjust the height of the adjustable top seat 20 so that the high-precision area array camera group 21 on the bottom surface of the adjustable top seat 20 is at a suitable testing distance from the laptop shell. Then, the bottom high-precision area array camera group 11 and the top high-precision area array camera group 21 are activated, and the CCD inspection cameras 12 arranged in a matrix on them start to work, performing comprehensive and high-precision optical inspection of the laptop shell from the bottom and the top respectively. During the testing process, the operator can view the testing data of each station in real time through the data display screen 22 on the outer wall of the adjustable top seat 20, which corresponds to the position of the fixed frame 40. After the inspection is completed, the laptop casing is removed, and the inspection data is recorded and analyzed in order to promptly identify and address any defects in the laptop casing.
