Description

Technical Field

[0001] The invention relates to the field of automatic detection equipment for air pressure and air flow sensors, and in particular to automatic detection equipment for air pressure and air flow sensors. Background Art

[0002] As the core component of electronic components, the accuracy and efficiency of the performance detection of air pressure and airflow sensors directly affect product quality and production efficiency. At present, the detection devices of conventional fine-sensitive sensors mostly adopt a linear assembly line layout, and various functional modules (such as loading, detection, sorting, etc.) are arranged in sequence, resulting in a long material transmission path, waiting time between detection processes, and overall low efficiency. In addition, traditional equipment relies on a single detection station and cannot achieve multi-parameter parallel detection. The degree of automation is insufficient and frequent manual intervention is required, which further restricts the improvement of detection speed. At the same time, the existing devices are prone to positioning errors during the detection process due to their loose structure and poor coordination, which affects the detection accuracy and consistency. Therefore, how to optimize the layout of the detection device and achieve efficient collaborative operation has become a technical problem that needs to be solved urgently in this field.

Each functional module is compactly arranged around the rotating detecting device, reducing the reciprocating moving distance of the material between the devices. At the same time, through the pneumatic coordinated control of the material sucking and transferring device and the material distributing and transferring device, high-speed and uninterrupted transmission is realized, significantly reducing the no-load waiting time.

The precise cooperation between the sliding table sensor and the limit component guarantees the positioning accuracy of the material sucking and transferring, avoiding the need for manual calibration. Through the limit rotation component of the rotating detecting table and the cooperation of multiple sensors, it is ensured that the rotation angle each time is strictly aligned with the detecting position. Combined with the multi-angle supplementary lighting of the double lighting device, the data reliability of the positive and negative pressure detection and image recording is effectively improved. Through the innovative spatial layout and automatic control strategy, this technical solution overcomes the technical bottlenecks of low detection efficiency and poor coordination of traditional equipment, providing a reliable guarantee for the high-volume production of sensors.
