Description

Technical Field

[0001] This utility model relates to the field of PCB board processing and inspection technology, and in particular to a three-coordinate moving lens device for an image inspection machine. Background Technology

[0002] PCB circuit boards typically have a complex multi-layered structure containing numerous electrical connections and solder joints. During the PCB manufacturing process, the machining accuracy and depth control of the board holes become crucial to ensuring the normal functioning of the PCB circuit board. Traditional testing methods rely heavily on manual operation, which is difficult to meet the high-precision and high-efficiency testing requirements of modern electronic products.

[0003] As PCB designs become increasingly complex, the number and types of holes continue to increase. Traditional manual inspection methods are no longer efficient and accurate enough to complete the task. Furthermore, hole depth is crucial to the reliability of electrical connections. Insufficient or excessive hole depth can lead to PCB malfunction. Therefore, it is necessary to use an image inspection machine to inspect the hole depth.

[0004] However, traditional testing devices typically use fixed clamps in their clamping systems, which are difficult to adjust to accommodate PCBs of different sizes and shapes. In the manufacturing process of electronic products, there are many types of circuit boards and frequent design iterations, and the fixed nature of the clamps limits the versatility of the equipment.

[0005] Therefore, in order to improve the quality requirements of electronic products using PCB circuit boards, it is urgent to design a three-coordinate moving lens device for the image inspection machine that enables the image inspection machine to move in three coordinates to meet the conditions for the image inspection machine to detect the hole depth of the PCB circuit board at different positions, and to make the clamping system change in real time according to the size of the PCB circuit board, so as to facilitate the inspection of holes in the PCB circuit board. Utility Model Content

[0015] 1. The three-coordinate moving lens device of the image inspection machine drives the first lead screw or the second lead screw to rotate through two sets of servo motors, which can realize the reciprocating movement of the first movable block or the second movable block on the first mounting box or the second mounting box, thereby driving the placement board to also make synchronous displacement, realizing synchronous movement or individual movement in the X-axis or Y-axis direction, so as to meet the hole depth detection requirements of different PCB circuit boards.
